Items 1 and 2. Business and Properties

OVERVIEW

Holly Energy Partners, L.P. (“HEP”) is a Delaware limited partnership engaged principally in the business of operating a system of petroleum product and crude pipelines, storage tanks, distribution terminals, loading rack facilities and refinery processing units in Texas, New Mexico, Utah, Nevada, Oklahoma, Wyoming, Kansas, Idaho and Washington. We were formed in Delaware in 2004 and maintain our principal corporate offices at 2828 N. Harwood, Suite 1300, Dallas, Texas 75201-1507. Our telephone number is 214-871-3555 and our internet website address is www.hollyenergy.com. The information contained on our website does not constitute part of this Annual Report on Form 10-K. A copy of this Annual Report on Form 10-K will be provided without charge upon written request to the Vice President, Investor Relations at the above address. A direct link to our filings at the U.S. Securities and Exchange Commission (“SEC”) website is available on our website on the Investors page. Also available on our website are copies of our Governance Guidelines, Audit Committee Charter, Compensation Committee Charter, and Code of Business Conduct and Ethics, all of which will be provided without charge upon written request to the Vice President, Investor Relations at the above address. In this document, the words “we,” “our,” “ours” and “us” refer to HEP and its consolidated subsidiaries or to HEP or an individual subsidiary and not to any other person. “HFC” refers to HollyFrontier Corporation and its subsidiaries, excluding HEP and its subsidiaries and Holly Logistic Services, L.L.C. (“HLS”), a subsidiary of HollyFrontier Corporation that is the ultimate general partner of HEP and manages HEP.

Through our subsidiaries and joint ventures we own and/or operate petroleum product and crude pipelines, terminal, tankage and loading rack facilities, and refinery processing units that support the refining and marketing operations of HFC and other refineries in the Mid-Continent, Southwest and Northwest regions of the United States. At December 31, 2021, HFC owned approximately 57% of our outstanding common units as well as a non-economic general partner interest. Our assets are categorized into a Pipelines and Terminals segment and a Refinery Processing Unit segment. Segment disclosures are discussed in Note 16 to our consolidated financial statements in Part II, Item 8.

We generate revenues by charging tariffs for transporting petroleum products and crude oil through our pipelines, by charging fees for terminalling and storing refined products and other hydrocarbons, providing other services at our storage tanks and terminals and charging a tolling fee per barrel or thousand standard cubic feet of feedstock throughput in our refinery processing units. We do not take ownership of products that we transport, terminal, store or process, and therefore, we are not directly exposed to changes in commodity prices.

We have a long-term strategic relationship with HFC that has historically facilitated our growth. Our future growth plans include organic projects around our existing assets and select investments or acquisitions that enhance our service platform while creating accretion for our unitholders. While in the near term, any acquisitions would be subject to the economic conditions discussed in “Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations -Overview - Impact of COVID-19 on Our Business” below, we also expect over the longer term to continue to work with HFC on logistic asset acquisitions in conjunction with HFC’s refinery acquisition strategies.

On August 2, 2021, HFC, Hippo Parent Corporation, a wholly owned subsidiary of HFC (“New Parent”), Hippo Merger Sub, Inc., a wholly owned subsidiary of New Parent (“Parent Merger Sub”), The Sinclair Companies (“Sinclair”), and Hippo Holding LLC, a wholly owned subsidiary of Sinclair (the “Target Company”), entered into a Business Combination Agreement (the “Business Combination Agreement”), pursuant to which HFC will acquire the Target Company. HFC will acquire the Target Company by effecting (a) a holding company merger in accordance with Section 251(g) of the Delaware General Corporation Law whereby HFC will merge with and into Parent Merger Sub, with HFC surviving such merger as a direct wholly owned subsidiary of New Parent (the “HFC Merger”) and (b) immediately following the HFC Merger, a contribution whereby Sinclair will contribute all of the equity interests of the Target Company to New Parent in exchange for shares of New Parent, resulting in the Target Company becoming a direct wholly owned subsidiary of New Parent (together with the HFC Merger, the “HFC Transaction”).

Additionally, on August 2, 2021, HEP, Sinclair and Sinclair Transportation Company, a wholly owned subsidiary of Sinclair (“STC”), entered into a Contribution Agreement (the “Contribution Agreement”) pursuant to which HEP will acquire all of the outstanding shares of STC in exchange for 21 million newly issued common units of HEP and cash consideration equal to $325 million (the “HEP Transaction” and together with the HFC Transaction, the “Sinclair Transactions”), subject to downward adjustment if, as a condition to obtaining antitrust clearance for the Sinclair Transactions, HEP agrees to divest a portion of its equity interest in UNEV Pipeline, LLC (“UNEV”) and the sales price for such interests does not exceed the threshold provided in the Contribution Agreement. The Sinclair Transactions are expected to close in 2022, subject to customary closing conditions and regulatory clearance, including the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust

- 7 -

Improvements Act (the “HSR Act”). The HEP Transaction is conditioned on the closing of the transactions contemplated by the Business Combination Agreement, which will occur immediately following the HEP Transaction.

PIPELINES AND TERMINALS

Pipelines

Our refined product pipelines transport light refined products from HFC’s Navajo refinery in New Mexico and a third party's refinery in Texas to their customers in the metropolitan and rural areas of Texas, New Mexico, Arizona, and Oklahoma and from various refineries in Utah, Wyoming, and Montana (including HFC's Woods Cross refinery in Utah) to Las Vegas, Nevada and Cedar City, Utah. The refined products transported in these pipelines include conventional gasolines, federal, state and local specification reformulated gasoline, low-octane gasoline for oxygenate blending, distillates that include high- and low-sulfur diesel and jet fuel and liquefied petroleum gases (“LPGs”) (such as propane, butane and isobutane).

Our intermediate product pipelines consist principally of three parallel pipelines that connect the Navajo refinery, Lovington and Artesia facilities. These pipelines primarily transport intermediate feedstocks and crude oil for HFC’s refining operations in New Mexico. We also own pipelines that transport intermediate product and gas between HFC's Tulsa East and West refinery facilities.

Our crude pipelines consist of crude oil trunk, gathering and connection pipelines located in West Texas, New Mexico, Kansas, Oklahoma, Utah and Wyoming that deliver crude oil to HFC's Navajo, El Dorado, Tulsa and Woods Cross refineries as well as other unaffiliated refineries.

Our pipelines are regularly inspected. Generally, other than as may be provided in certain pipelines and terminal agreements, substantially all of our pipelines are unrestricted as to the direction in which product flows and the types of crude and refined products that we can transport on them. The Federal Energy Regulatory Commission (“FERC”) regulates the transportation tariffs for interstate shipments on our refined product and crude oil pipelines and state regulatory agencies regulate the transportation tariffs for intrastate shipments on our pipelines.

HFC shipped an aggregate of 69% of the petroleum products transported on our refined product pipelines, 100% of the throughput volumes transported on our intermediate pipelines, and 68% of the throughput on our crude pipelines in 2021.

The following table details the average aggregate daily number of barrels of petroleum products transported on our pipelines in each of the periods set forth below for HFC and for third parties.

	Years Ended December 31,
	2021	2020	2019	2018	2017
Volumes transported for barrels per day (“bpd”):
HFC	513,506	529,905	633,270	622,088	556,516
Third parties	178,440	156,376	204,052	187,717	99,847
Total	691,946	686,281	837,322	809,805	656,363
Total barrels in thousands (“mbbls”)	252,560	251,178	305,623	295,579	239,572

Terminals, Loading Racks and Refinery and Renewable Diesel Facility Tankage

Our refined product terminals receive products from pipelines connected to HFC’s refineries and other third party refineries. We then distribute them to HFC and third parties, who in turn deliver them to end-users and retail outlets. Our terminals are generally complementary to our pipeline assets and serve the marketing activities of HFC and other customers. Terminals play a key role in moving product to the end-user market by providing the following services:

•distribution;

•blending to achieve specified grades of gasoline and diesel, including the blending of butane, ethanol and biodiesel;

•other ancillary services that include the injection of additives and filtering of jet fuel; and

•storage and inventory management.

Typically, our refined product terminal facilities consist of multiple storage tanks and are equipped with automated truck loading equipment that operates 24 hours a day. This automated system provides for control of security, allocations, and credit and carrier certification by remote input of data by our customers. In addition, nearly all of our terminals are equipped with truck loading racks capable of providing automated blending to individual customer specifications.

Our refined product terminals derive most of their revenues from terminalling fees paid by customers. We charge a fee for transferring refined products from the terminal to trucks or to pipelines connected to the terminal. In addition to terminalling fees, we generate revenues by charging our customers fees for storage, blending, injecting additives, and filtering jet fuel. HFC currently accounts for the substantial majority of our refined product terminal revenues.

Our crude terminal receives crude from Osage Pipe Line Company, LLC's (“Osage”) pipeline and derives most of its revenues from throughput charges.

The table below sets forth the total average throughput for our refined product and crude terminals in each of the periods presented:

CONTROL OPERATIONS OF PIPELINES AND TERMINALS

All of our pipelines are operated via satellite, microwave and radio systems from our central control room located in Artesia, New Mexico. We also monitor activity at our terminals from this control room. The control center operates with state-of-the-art Supervisory Control and Data Acquisition, or SCADA, systems. Our control center is equipped with computer systems designed to continuously monitor operational data, including refined product and crude oil throughput, flow rates, and pressures. In addition, the control center monitors alarms and throughput balances. The control center operates remote pumps, motors, engines, and valves associated with the delivery of refined products and crude oil. The computer systems are designed to enhance leak-detection capabilities, sound automatic alarms if operational conditions outside of pre-established parameters occur, and provide for remote-controlled shutdown of pump stations on the pipelines.

REFINERY PROCESSING UNITS

Our refinery processing units are integrated in HFC's El Dorado, Kansas refinery and HFC's Woods Cross, Utah refinery and are used to support their daily operations, which chemically transform crude oil into various petroleum products, including gasoline, diesel, LPGs and asphalt.

HFC has committed to supply these units with a minimum feedstock throughput for each calendar quarter. HEP has committed that these units yield a certain level of petroleum product. The initial terms for the refinery processing units at HFC's El Dorado and Woods Cross refineries extend through 2030 and 2031, respectively.

The El Dorado units were first operational in the third and fourth quarters of 2015 and the Woods Cross units were first operational in the second quarter of 2016. These units operate on a daily basis until they are taken down for large-scale maintenance, which can be every two to four years and could last from two to four weeks. During this maintenance period (turnaround), the minimum feedstock throughput is adjusted so that HFC is not penalized for HEP's maintenance requirements.

HEP's revenue is primarily generated from the minimum throughput commitments, and HEP charges a tolling fee per barrel or thousand standard cubic feet of throughput. The tolling fee is meant to provide HEP with revenue that surpasses the amount of its expected operating costs, which include natural gas and maintenance. On any calendar month where the cost of natural gas exceeds what is included in the tolling fee, HEP will charge HFC for recovery of this additional cost. Additionally, if turnaround costs are more than expected after the first turnaround for each unit, the tolling fee will be permanently adjusted, one time, to recover these costs.

Our refinery processing units are managed by refinery personnel seconded from HFC; significant assets are grouped accordingly and described below.

El Dorado Refinery

Naphtha Fractionation Unit - El Dorado, Kansas refinery facility

The feedstock used by the naphtha fractionation unit is desulfurized naphtha, which is produced by the refinery earlier in the refining process. Desulfurized naphtha is a key component in gasoline, and this unit is used to reduce the level of benzene precursors. This allows the resulting product to be processed further to produce gasoline that meets regulatory requirements. The unit's feedstock capacity is 50,000 bpd of desulfurized naphtha.

Hydrogen Generation Unit - El Dorado, Kansas refinery facility

The hydrogen unit primarily uses natural gas as a feedstock to produce hydrogen gas that is used in HFC's operation of its El Dorado, Kansas refinery. This feedstock is supplied from purchased natural gas. The hydrogen unit's natural gas feedstock capacity is 6,100 thousand standard cubic feet per day.

Woods Cross Refinery

Crude Unit - Woods Cross, Utah refinery facility

The crude unit is comprised of several components, primarily an atmospheric distillation tower, a desalter and heat exchangers, together referred to as the crude unit. The crude unit uses black wax and other crudes as feedstock and is the first step in the refining process to separate crude into refined products. This process is accomplished by heating the crude until it is distilled into various intermediate streams. These intermediate streams are further refined downstream of the crude unit. The initial rejection of major contaminants is also performed by the crude unit. Its feedstock capacity is 15,000 bpd of crude oil.

- 16 -

Fluid Catalytic Cracking Unit - Woods Cross, Utah refinery facility

The fluid catalytic cracking unit (“FCC”) is used to convert the high-boiling, high-molecular weight hydrocarbon fractions of crude oil to more valuable products like gasoline, diesel and LPGs. This conversion is performed by the cracking of petroleum hydrocarbons achieved from extremely high temperatures and fluidized catalyst. The FCC's capacity is 8,000 bpd of atmospheric tower bottoms from the crude unit, discussed above, and gas oil.

Polymerization Unit - Woods Cross, Utah refinery facility

The polymerization unit uses the LPGs, propylene and butylene, from the FCC unit and polymerizes them into high octane gasoline blendstock using heat and catalysts. This gasoline blendstock is combined with other blendstocks in the refinery to make finished gasoline. The polymerization unit's feedstock capacity is 2,500 bpd.

INVESTMENT IN JOINT VENTURE

On October 2, 2019, HEP Cushing LLC (“HEP Cushing”), a wholly-owned subsidiary of HEP, and Plains Marketing, L.P., a wholly-owned subsidiary of Plains, formed a 50/50 joint venture, Cushing Connect Pipeline & Terminal LLC (the “Cushing Connect Joint Venture”), for (i) the development, construction, ownership and operation of a new 160,000 barrel per day common carrier crude oil pipeline (the “Cushing Connect Pipeline”) that will connect the Cushing, Oklahoma crude oil hub to the Tulsa, Oklahoma refining complex owned by a subsidiary of HFC and (ii) the ownership and operation of 1.5 million barrels of crude oil storage in Cushing, Oklahoma (the “Cushing Connect JV Terminal”). The Cushing Connect JV Terminal went in service during the second quarter of 2020, and the Cushing Connect Pipeline was placed into service at the end of the third quarter of 2021. Long-term commercial agreements have been entered into to support the Cushing Connect Joint Venture assets.

The Cushing Connect Joint Venture has contracted with an affiliate of HEP to manage the construction and operation of the Cushing Connect Pipeline and with an affiliate of Plains to manage the operation of the Cushing Connect JV Terminal. The total Cushing Connect Joint Venture investment will generally be shared equally among HEP and Plains. However, we are solely responsible for any Cushing Connect Pipeline construction costs that exceed the budget by more than 10%. HEP estimates its share of the cost of the Cushing Connect JV Terminal contributed by Plains and Cushing Connect Pipeline construction costs are approximately $70 million to $75 million, including $4 million to $6 million of Cushing Connect Pipeline construction costs exceeding the budget by more than 10% to be borne solely by HEP.

The investment above and the basis of presentation is described further in Note 3 in notes to consolidated financial statements of HEP, and the description in Note 3 is incorporated herein by reference.

AGREEMENTS WITH HFC

We serve HFC's refineries under long-term pipeline, terminal, tankage and refinery processing unit throughput agreements expiring from 2022 to 2036. Under these agreements, HFC agrees to transport, store, and process throughput volumes of refined products, crude oil and feedstocks on our pipelines, terminal, tankage, loading rack facilities and refinery processing units that result in minimum annual payments to us. These minimum annual payments or revenues are subject to annual rate adjustments on July 1st each year based on the PPI or the FERC index. On December 17, 2020, FERC established a new price index for the five-year period commencing July 1, 2021 and ending June 30, 2026, in which common carriers charging indexed rates are permitted to adjust their indexed ceilings annually by Producer Price Index plus 0.78%. FERC received requests for rehearing of its December 17, 2020 order, and on January 20, 2022, FERC revised the index level used to determine annual changes to interstate oil pipeline rate ceilings to Producer Price Index minus 0.21%. The order requires the recalculation of the July 1, 2021 index ceilings to be effective as of March 1, 2022. This revision in rates will not have a material adverse effect on our results of operations. As of December 31, 2021, our agreements with HFC required minimum annualized payments to us of $352.8 million.

If HFC fails to meet its minimum volume commitments under the agreements in any quarter, it will be required to pay us the amount of any shortfall in cash by the last day of the month following the end of the quarter. Under certain of the agreements, a shortfall payment may be applied as a credit in the following four quarters after minimum obligations are met.

A significant reduction in revenues under these agreements could have a material adverse effect on our results of operations.

Furthermore, if new laws or regulations that affect terminals or pipelines are enacted that require us to make substantial and unanticipated capital expenditures at the pipelines or terminals, we will have the right after we have made efforts to mitigate their effects to negotiate a monthly surcharge on HFC for the use of the terminals or to file for an increased tariff rate for use of the pipelines to cover HFC’s pro rata portion of the cost of complying with these laws or regulations including a reasonable rate

- 17 -

of return. In such instances, we will negotiate in good faith with HFC to agree on the level of the monthly surcharge or increased tariff rate.

On June 1, 2020, HFC announced plans to permanently cease petroleum refining operations at its Cheyenne refinery and to convert certain assets at that refinery to renewable diesel production. HFC subsequently began winding down petroleum refining operations at its Cheyenne refinery on August 3, 2020.

As of December 31, 2020, our throughput agreement with HFC required minimum annualized payments to us of approximately $17.6 million related to our Cheyenne assets. However, HEP and HFC reached an agreement to terminate the existing minimum volume commitments for HEP's Cheyenne assets and enter into new agreements, which were finalized and executed on February 8, 2021, with the following terms, in each case effective January 1, 2021: (1) a ten-year lease with two five-year renewal option periods for HFC’s use of certain HEP tank and rack assets in the Cheyenne refinery to facilitate renewable diesel production with an annual lease payment of approximately $5 million, (2) a five-year contango service fee arrangement that will utilize HEP tank assets inside the Cheyenne refinery where HFC will pay a base tariff to HEP for available crude oil storage and HFC and HEP will split any profits generated on crude oil contango opportunities, and (3) a $10 million one-time cash payment from HFC to HEP for the termination of the existing minimum volume commitment.

Omnibus Agreement

Under certain provisions of an omnibus agreement we have with HFC (the “Omnibus Agreement”), we pay HFC an annual administrative fee ($2.6 million in 2021) for the provision by HFC or its affiliates of various general and administrative services to us. This fee includes expenses incurred by HFC to perform centralized corporate functions, such as executive management, legal, accounting, treasury, information technology and other corporate services, including the administration of employee benefit plans. This fee does not include the salaries of personnel employed by HFC who perform services for us on behalf of HLS or the cost of their employee benefits, which are separately charged to us by HFC. We also reimburse HFC and its affiliates for direct expenses they incur on our behalf. In addition, we also pay for our own direct general and administrative costs, including costs relating to operating as a separate publicly held entity, such as costs for preparation of partners’ K-1 tax information, SEC filings, directors’ compensation, and registrar and transfer agent fees.

Under HLS’s secondment agreement with HFC (the “Secondment Agreement”), certain employees of HFC are seconded to HLS, our ultimate general partner, to provide operational and maintenance services for certain of our processing, refining, pipeline and tankage assets, and HLS reimburses HFC for its prorated portion of the wages, benefits, and other costs of these employees for our benefit.

COMPETITION

As a result of our physical integration with HFC’s refineries, our contractual relationship with HFC under the Omnibus Agreement and the HFC pipelines and terminals, tankage and throughput agreements, we believe that we will not face significant competition for barrels of crude oil transported to or refined products transported from HFC’s refineries, particularly during the terms of our long-term transportation agreements with HFC expiring between 2022 and 2036.

However, we do face competition from other pipelines that may be able to supply the end-user markets of HFC or other customers with refined products on a more competitive basis. Additionally, if HFC’s wholesale customers reduced their purchases of refined products due to the increased availability of cheaper product from other suppliers, decreased demand for refined products or for other reasons, the volumes transported through our pipelines could be reduced, which, subject to the minimum revenue commitments, could cause a decrease in cash and revenues generated from our operations.

The petroleum refining business is highly competitive. Among HFC’s competitors are some of the world’s largest integrated petroleum companies, which have their own crude oil supplies and distribution and marketing systems. HFC competes with independent refiners as well. Competition in particular geographic areas is affected primarily by the amounts of refined products produced by refineries located in such areas and by the availability of refined products and the cost of transportation to such areas from refineries located outside those areas.

In addition, we face competition from trucks that deliver product in a number of areas we serve. Although their costs may not be competitive for longer hauls or large volume shipments, trucks compete effectively for incremental and marginal volumes in many areas we serve. The availability of truck transportation places some competitive constraints on us.

Our refined product terminals compete with other independent terminal operators as well as integrated oil companies based on terminal location, price, versatility and services provided. Our competition primarily comes from integrated petroleum companies, refining and marketing companies, independent terminal companies and distribution companies with marketing and trading arms. Historically, the significant majority of the throughput at our terminal facilities has come from HFC.

GOVERNMENTAL REGULATION

Safety and Maintenance

Many of our pipelines are subject to regulation by the Pipeline and Hazardous Materials Safety Administration (“PHMSA”) of the Department of Transportation. PHMSA has promulgated regulations governing, among other things, maximum operating pressures, pipeline patrols and leak surveys, control room management, and emergency procedures, as well as other matters intended to prevent accidents and failures. Additionally, PHMSA has promulgated regulations requiring pipeline operators to develop and implement integrity management programs for certain pipelines that, in the event of a pipeline leak or rupture, could affect “high consequence areas,” which are areas where a release could have the most significant adverse consequences, including high-population areas, certain drinking water sources and unusually sensitive ecological areas.

In addition, many states have adopted regulations, similar to, or which go above and beyond, existing PHMSA regulations, for certain intrastate pipelines. For example, Texas has developed regulatory programs that largely parallel the federal regulatory scheme and impose additional requirements for certain pipelines. Furthermore, other related programs, such as the EPA’s Risk Management Program and the Occupational Safety and Health Administration’s Process Safety Management standard apply to some of our terminals and associated facilities.

We perform preventive and normal maintenance on all of our pipeline and terminal systems and make repairs and replacements when necessary or appropriate. We also conduct routine and required inspections of our pipelines and other assets as required by regulations. Corrosion inhibitors, external coatings and impressed current cathodic protection systems are used to protect against internal and external corrosion. We regularly monitor, test and record the effectiveness of these corrosion-control systems. We monitor the structural integrity of covered segments of our pipeline systems through a program of periodic internal inspections using electronic “smart pigs”, hydrostatic testing, and other measures. We follow these inspections with a review of the data, and we make repairs as necessary to maintain the integrity of the pipeline. We have initiated a risk-based approach to prioritizing the pipeline segments for future smart pig runs or other appropriate integrity testing methods. This approach is intended to allow the pipelines that have the greatest risk potential to receive the highest priority in being scheduled for inspections or pressure tests for integrity. Nonetheless, the adoption of new or amended regulations or the reinterpretation of existing laws and regulations by PHMSA or states that result in more stringent or costly pipeline integrity management or safety standards could possibly have a substantial effect on us and similarly situated midstream operators.

Maintenance facilities containing equipment for pipe repairs, spare parts, and trained response personnel are located along the pipelines. Employees participate in simulated spill response exercises on a regular basis. They also participate in actual spill response boom deployment exercises in planned spill scenarios in accordance with Oil Pollution Act of 1990 requirements.

At our terminals, tanks designed for gasoline storage are equipped with internal or external floating roofs that minimize emissions and prevent potentially flammable vapor accumulation between fluid levels and the roof of the tank. Our terminal facilities have facility response plans, spill prevention and control plans, and other plans and programs to respond to emergencies.

Many of our terminal loading racks are protected with water deluge systems activated by either heat sensors or an emergency switch. Several of our terminals are also protected by foam systems that are activated in case of fire. All of our terminals participate in a comprehensive environmental management program to assure compliance with applicable air, solid waste and wastewater regulations.

For further information on pipeline safety and regulatory requirements related to maintenance, see our risk factor “Our operations are subject to evolving federal, state and local laws, regulations and permit/authorization requirements regarding our business, capital projects, environmental protection, health, operational safety and product quality. Potential liabilities arising from these laws, regulations and requirements could affect our operations and adversely affect our performance.”

Rate Regulation

Some of our existing pipelines are considered interstate common carrier pipelines subject to regulation by FERC under the Interstate Commerce Act (the “ICA”). The ICA requires that the rates charged for transportation on oil pipelines, a category that includes crude oil and petroleum product pipelines, be just and reasonable and not unduly discriminatory. The FERC regulations implementing the ICA further require that the rates and rules for transportation service on our oil pipelines be filed with the FERC. The ICA permits interested persons to challenge newly proposed or changed rates or rules and authorizes FERC to suspend the effectiveness of such proposed rates or rules for a period of up to seven months and to investigate such rates. If, upon completion of an investigation, FERC finds that the proposed rate is unlawful, it is authorized to require the carrier to refund the revenues collected during the pendency of the investigation that are in excess of the amount the FERC determines to be just and reasonable. FERC also may investigate, upon complaint or on its own motion, rates that are already in effect and

- 19 -

may order a carrier to change its rates prospectively. Upon an appropriate showing, a shipper may obtain reparations for damages sustained during the two years prior to the filing of a complaint.

Oil pipeline carriers may change their rates in accordance with a FERC-approved indexing methodology, which allows oil pipeline carriers to charge rates up to a prescribed ceiling level that changes annually based on the year-to-year change in the U.S. Producer Price Index for Finished Goods (“PPI”). Shippers may protest rate increases made within the ceiling levels, but such protests must show that the portion of the rate increase resulting from application of the index is substantially in excess of the oil pipeline’s increase in costs from the previous year. Oil pipeline carriers as a general rule utilize this indexing methodology to change their rates. Cost-of-service ratemaking, market-based rates and settlement rates are alternatives to the indexing approach and may be used in certain specified circumstances to change rates.

For the five-year period ending June 30, 2021, oil pipeline carriers were permitted to adjust the indexed rate ceiling annually by PPI plus 1.23%. On December 17, 2020, the FERC issued a final rule setting the index for the five-year period beginning July 1, 2021 at PPI plus 0.78%. Because the index was negative, oil pipeline carriers, including our pipelines, were required to reduce rates that would otherwise be above the indexed rate ceiling. Several shippers requested rehearing of the FERC’s order and, on January 20, 2022, the FERC issued an order further reducing the index to PPI minus 0.21%. As a result, oil pipeline carriers are required to further reduce rates that would be above the new indexed rate ceiling by March 1, 2022. Such reduced rates will be in effect from March 1, 2022 until July 1, 2022. Prior to June 1, 2022, the FERC will issue a revised index, which could be positive or negative. Rates reflecting this revised index will become effective on July 1, 2022.

The Energy Policy Act of 1992 deemed oil pipeline tariff rates that were (i) in effect for the 365-day period ending on the date of enactment or (ii) in effect on the 365th day preceding enactment and had not been subject to complaint, protest or investigation during the 365-day period, in each case, to be just and reasonable or “grandfathered” under the ICA. The Energy Policy Act also limited the circumstances under which a complaint can be made against such grandfathered rates.

While FERC regulates the rates for interstate shipments on our refined product pipelines, the New Mexico Public Regulation Commission regulates the rates for intrastate shipments in New Mexico, the Texas Railroad Commission regulates the rates for intrastate shipments in Texas and the Oklahoma Corporation Commission regulates the rates for intrastate shipments in Oklahoma. These state commissions have generally not been aggressive in regulating common carrier pipelines and generally have not investigated the rates or practices of petroleum pipelines in the absence of shipper complaints, and we do not believe the intrastate tariffs now in effect are likely to be challenged. However, a state regulatory commission could investigate our rates if such a challenge were filed.

In addition, if any of our pipelines were found to have provided services or otherwise operated in violation of the ICA, this could result in the imposition of administrative and criminal remedies and civil penalties, as well as a requirement to disgorge charges collected for such services in excess of the rate established by the FERC. Any of the foregoing could adversely affect revenues and cash flow related to the affected assets.

Our operation of pipelines, terminals, and associated facilities in connection with the transportation and storage of refined products and crude oil is subject to stringent and complex federal, state, and local laws and regulations governing the potential discharge of materials into the environment, or otherwise relating to the protection of human health and the environment and natural resources. These laws and regulations may require us to obtain permits for our operations or result in the imposition of strict requirements relating to air emissions, and characteristics and composition of gasoline and diesel fuels, biodiversity, wastewater discharges, waste management, process safety and risk management, spill planning and prevention and the remediation of spills, leaks and other contamination. As with the industry generally, compliance with existing, changing, and new laws, regulations, interpretations and guidance increases our overall cost of business, including our capital costs to construct, maintain, upgrade and operate equipment and facilities. These laws and regulations affect our operations, maintenance, capital expenditures and net income, as well as those of our competitors. These existing and any new laws and regulations, and the interpretation or enforcement thereof, are subject to frequent change by regulatory authorities, and we are unable to predict the ongoing cost to us of complying with these laws and regulations or the future impact of these laws and regulations on our operations. Violation of environmental laws, regulations, and permits can result in the imposition of significant administrative, civil and criminal penalties, and injunctions, construction bans or delays; delays in the permitting, development or expansion of projects; limitations or prohibitions on certain operations; and reputational harm. In addition, many environmental laws contain citizen suit provisions, allowing environmental groups to bring suits to enforce compliance with environmental laws. Environmental groups frequently challenge pipeline infrastructure projects. Moreover, a major discharge of hydrocarbons or hazardous substances into the environment could, to the extent the event is not insured, subject us to substantial expense, including the cost of remediation and restoration of any damaged natural resources, the cost to comply with applicable laws and regulations, and claims made by employees, neighboring landowners and other third parties for personal injury and property damage.

Contamination resulting from spills of refined products and crude oil is not unusual within the petroleum pipeline industry. Historic spills along our existing pipelines and terminals as a result of past operations have resulted in contamination of the environment, including soils and groundwater. Some environmental laws impose liability without regard to fault or the legality of the original act on certain classes of persons that contributed to the releases of hazardous substances or petroleum hydrocarbon substances into the environment. These persons include the owner or operator of the site or sites where the release occurred and companies that disposed of, or arranged for the disposal of, the hazardous substances found at the site. Such persons may be subject to strict, joint and several liability for the costs of cleaning up the hazardous substances that have been released into the environment, for damages to natural resources, and for the costs of certain health studies. Site conditions, including soils and groundwater, are being evaluated at a few of our properties where operations may have resulted in releases of hydrocarbons and other wastes, none of which we believe will have a significant effect on our operations since the remediation of such releases would be covered under environmental indemnification agreements.

Under the Omnibus Agreement and certain transportation agreements and purchase agreements with HFC, HFC has agreed to indemnify us, subject to certain monetary and time limitations, for environmental noncompliance and remediation liabilities associated with certain assets transferred to us from HFC and occurring or existing prior to the date of such transfers.

We have an environmental agreement with Delek with respect to pre-closing environmental costs and liabilities relating to the pipelines and terminals acquired from Delek in 2005, under which Delek will indemnify us subject to certain monetary and time limitations.

There are environmental remediation projects that are currently in progress that relate to certain assets acquired from HFC. Certain of these projects were underway prior to our purchase and represent liabilities of HFC as the obligation for future remediation activities was retained by HFC. At December 31, 2021, we have an accrual of $3.9 million that relates to environmental clean-up projects for which we have assumed liability or for which the indemnity provided for by HFC has expired. The remaining projects, including assessment and monitoring activities, are covered under the HFC environmental indemnification discussed above and represent liabilities of HFC.

We may experience future releases into the environment from our pipelines and terminals or discover historical releases that were previously unidentified or not assessed. Although we maintain an extensive inspection and audit program designed, as applicable, to prevent, detect and address these releases promptly, damages and liabilities incurred due to any future environmental releases from our assets have the potential to substantially affect our business.

CAPITAL REQUIREMENTS

Our pipeline and terminalling operations are capital intensive, requiring investments to maintain, expand, upgrade or enhance existing operations and to meet environmental and operational regulations. Our capital requirements have consisted of, and are expected to continue to consist of, maintenance capital expenditures and expansion capital expenditures. “Maintenance capital expenditures” represent capital expenditures to replace partially or fully depreciated assets to maintain the operating capacity of existing assets. Maintenance capital expenditures include expenditures required to maintain equipment reliability, tankage and pipeline integrity, safety and to address environmental regulations. “Expansion capital expenditures” represent capital expenditures to expand the operating capacity of existing or new assets, whether through construction or acquisition. Expansion capital expenditures include expenditures to acquire assets, to grow our business and to expand existing facilities, such as projects that increase throughput capacity on our pipelines and in our terminals. Repair and maintenance expenses associated with existing assets that are minor in nature and do not extend the useful life of existing assets are charged to operating expenses as incurred.

Each year the board of directors of HLS, our ultimate general partner, approves our annual capital budget, which specifies capital projects that our management is authorized to undertake. Additionally, at times when conditions warrant or as new opportunities arise, additional projects may be approved. The funds allocated for a particular capital project may be expended over a period in excess of a year, depending on the time required to complete the project. Therefore, our planned capital expenditures for a given year consist of expenditures approved for capital projects included in the current year's capital budget as well as, in certain cases, expenditures approved for capital projects in capital budgets for prior years. Our current 2022 capital forecast is comprised of approximately $15 million to $20 million for maintenance capital expenditures, $35 million to $50 million for refinery unit turnarounds and $5 to $10 million for expansion capital expenditures, excluding any expenditures related to the HEP Transaction. In addition to our capital budget, we may spend funds periodically to perform capital upgrades or additions to our assets where a customer reimburses us for such costs. The upgrades or additions would generally benefit the customer over the remaining life of the related service agreements.

- 21 -

We expect that our currently planned sustaining and maintenance capital expenditures, as well as expenditures for capital development projects, will be funded with cash generated by operations. We expect that, to the extent necessary, we can raise additional funds from time to time through equity or debt financings in the public and private capital markets.

Under the terms of the transaction to acquire HFC's 75% interest in UNEV, we issued to HFC a Class B unit comprising a noncontrolling equity interest in a wholly-owned subsidiary subject to redemption to the extent that HFC is entitled to a 50% interest in our share of annual UNEV earnings before interest, income taxes, depreciation and amortization above $30 million beginning July 1, 2015, and ending in June 2032, subject to certain limitations. However, to the extent earnings thresholds are not achieved, no redemption payments are required. No redemption payments have been required to date.

HUMAN CAPITAL

Our People

We are managed by HLS, our ultimate general partner. HLS is a subsidiary of HFC. The employees providing services to us are either provided by HLS, which utilizes people employed by HFC to perform services for us, or seconded to us by subsidiaries of HFC, as neither we nor our ultimate general partner have any employees. Under the Secondment Agreement with HFC, certain employees of HFC are seconded to HLS, our ultimate general partner, to provide operational and maintenance services for certain of our processing, refining, pipeline and tankage assets, and HLS reimburses HFC for its prorated portion of the wages, benefits, and other costs of these employees for our benefit. In addition, as more fully described under Part III, Item 11. Executive Compensation, certain executive officers of HLS are also executive officers of HFC and devote as much of their professional time as necessary to oversee the management our business and affairs.

The “One HFC Culture” focuses on five key values – safety, integrity, teamwork, ownership and inclusion. These values influence decisions, shape behaviors and provide the opportunity for employees to thrive. Safety is first. We care about our people and have implemented policies and procedures designed to help make sure they return home safely every day. We focus on integrity and doing the right thing. We champion a culture of teamwork and ownership by supporting each other and empowering employees to take action where they see a need or opportunity. Inclusion reflects our desire to foster a work environment in which employees feel valued and included in decisions, opportunities and challenges.

As of December 31, 2021, 302 HFC employees were dedicated to our business in addition to HFC employees seconded to HLS for a portion of their time to provide services to our business as described above. From time to time, a portion of HFC’s employees that are seconded to us, are covered by collective bargaining agreements having various expiration dates between 2022 and 2024. We have experienced no material interruptions of operations due to disputes with those employees and management believes that positive working relationships exist between HFC and local unions and their members.

Oversight

As a result of our secondment arrangements with HFC, strategic oversight for human capital management is shared between the HLS Board of Directors and board committees and the HFC Board of Directors and board committees. As further discussed under Part III, Item 11. Executive Compensation, the HLS Compensation Committee determines cash and bonus compensation for HLS’s Chief Executive Officer, President or Chief Financial Officer if such officers are solely dedicated to HLS. The HFC Board of Directors and Board committees provide oversight on strategies and policies related to the human capital management of HFC employees seconded to, and shared with, HLS. The HFC Compensation Committee is responsible for periodically reviewing HFC’s strategies and policies regarding the promotion of employee diversity, equity and inclusion, talent and performance management, pay equity and employee engagement, as well as executive succession planning. The HLS Board of Directors and HFC’s Nominating, Governance and Social Responsibility Committee oversee policies and practices regarding human rights in their respective operations and supply chain. This high level oversight is designed to ensure that our actions are well aligned with our strategies in attracting, retaining and developing a workforce that aligns with our values and strategies.

Diversity & Inclusion

HLS and HFC leadership is committed to attracting, retaining and developing a highly engaged, high-performing, diverse workforce and cultivating an inclusive workplace where all employees feel valued and have a sense of belonging. Increasing diversity and inclusion efforts is an organizational priority for HLS and HFC. HFC has introduced diversity awareness programs focused on increasing the number of underrepresented persons in engineering roles. HFC’s university recruiting team has partnered with historically black colleges and universities to offer full-time and summer internship opportunities and various diversity and inclusion organizations at universities to sponsor and participate in events, such as the North Texas Women’s Energy Network and the National Society of Black Engineers Convention. In addition, to help foster a culture of inclusion, HFC has two employee resource groups, one focused on developing talent at HFC by fostering relationships through education, networking and leadership development opportunities and the other focused on veterans. In 2021, HFC formed an

- 22 -

Inclusion and Diversity Working Group to develop and further implement HFC’s inclusion and diversity initiatives, to gather and report best practices related to inclusion and diversity, and to assist in developing ongoing inclusion and diversity goals and objectives.

Health & Safety

The safety of our employees, contractors and communities is an overarching priority and fundamental to our operational success. We have a comprehensive Pipeline Excellence Program that builds upon best practices and processes and is designed to advance organizational safety and performance, drive reliability and deliver strong results. Our approach allows for flexibility in unique operations and environments and provides a model for continuous improvement and fosters a strong culture of safety within our company. Pipelines are a vital component of our nation’s infrastructure, making it imperative that we safeguard our pipelines against any type of damage. We have implemented rigorous awareness and damage prevention programs that aim to educate the public and other key stakeholders and continually invest in the maintenance and integrity of our assets, including inspection and repair programs to comply with federal and state regulations. In response to the COVID-19 pandemic, and with the health and safety of all of our employees as a top priority, we have modified our business practices by limiting employee and contractor presence at our facilities to essential operating personnel, using a work from home policy, restricting travel, and quarantining personnel when necessary.

Total Rewards & Development

We believe that the health of our company is linked to the performance and health of our people. The HFC employees that provide service to us are eligible to participate in the same comprehensive and competitive total rewards programs that are provided to employees of HFC generally. HFC’s benefit offerings are designed to support employee health, financial and emotional needs, inclusive of comprehensive coverage for health care, a competitive retirement savings benefit, vacation and holiday time and other income protection and work life benefits. HFC also provides tools to help recognize and reward employee performance consistent with the One HFC Culture.

Consistent with the HFC culture values of ownership and growth, HFC offers training, development and engagement programs to its employees that provide services to us which provide employees the opportunity to develop their career by enhancing skills and capabilities consistent with the needs of the business. In 2019, HFC launched LEAD. It stands for Leadership Excellence and Development and is comprised of a number of programs focused on developing current and future leaders, including Future HFC Leader Development, Front Line Leader, and Leading the HFC Way programs.

Item 1A.Risk Factors

Risk Factor Summary

Investing in us involves a degree of risk. You should carefully consider all information in this Form 10-K, including the Management’s Discussion & Analysis section and the financial statements and related notes, prior to investing in our common units. These risks and uncertainties include, but are not limited to, the following:

Risks Related to our Business/Industry:

•We depend on HFC for a substantial portion of our revenues. A significant reduction in those revenues or a material deterioration of HFC's financial condition could reduce our revenues materially.

•Due to our lack of asset and geographic diversification, an adverse development in our businesses could materially and adversely affect our financial condition, results of operations, or cash flows.

•The COVID-19 pandemic, actions taken in response thereto, and certain global oil market developments have had and may continue to have a material adverse effect on our business.

•A material decrease in the supply, or a material increase in the price, of crude oil or other materials available to HFC's refineries and our pipelines and terminals, and a corresponding decrease in demand for refined products in the markets served by our pipelines and terminals, could reduce our revenues materially.

•Competition from other pipelines that may be able to supply our shippers' customers with refined products at a lower price could cause us to reduce our rates or could reduce our revenues. Any reduction in the capacity of, or the allocations to, our shippers on interconnecting, third-party pipelines could cause a reduction of volumes transported in our pipelines and through our terminals.

•Our business may suffer due to a change in the composition of our Board of Directors, the departure of any of our key senior executives or other key employees who provide services to us.

•If we are unable to complete capital projects at their expected costs or in a timely manner, incur increased maintenance or repair costs on assets, or if assumed market conditions deteriorate, our financial condition, results of operations, or cash flows could be materially and adversely affected.

•We may not be able to fully execute our growth strategy if we encounter illiquid capital markets or increased competition for investment opportunities, if our assumptions concerning population growth are inaccurate, or if an agreement cannot be reached with HFC for the acquisition of assets on which we have a right of first offer.

•Our operations are subject to catastrophic losses, operational hazards and unforeseen interruptions for which we may not be adequately insured. We could be subject to damages based on claims brought against us by our customers or lose customers as a result of the failure of products we distribute to meet certain quality specifications.

•We do not own all of the land on which our pipeline systems and other assets are located, which could result in disruptions to our operations. Regulatory changes related to a state’s use of eminent domain could inhibit our ability to secure rights-of-way for future pipeline construction projects.

•Terrorist attacks, and the threat of terrorist attacks or vandalism, have resulted in increased costs to our business. Global hostilities may adversely impact our results of operations.

•We own certain of our systems through joint ventures, and our control of such systems is limited by provisions of the agreements we have entered into with our joint venture partners and by our percentage ownership in such enterprises.

Risks Related to our Acquisition Strategy and Recent/Pending Acquisitions

•We may be unsuccessful in integrating the operations of acquired assets and in realizing the anticipated benefits of any such acquisitions.

•The pending Sinclair Transactions may not be consummated on a timely basis or at all. To complete the Sinclair Transactions, HFC and Sinclair must obtain certain governmental approvals, and if such approvals are not granted or are granted with conditions that become applicable to the parties, completion of the transactions may be jeopardized or prevented or the anticipated benefits of the transactions could be reduced. The actual value of the consideration we will pay to Sinclair at closing may exceed the value allocated at the time we entered into the Contribution Agreement.

•We will issue a large number of common units in connection with the Sinclair Transactions, which will result in dilution to our existing unitholders and may cause the market price of our common units to decline as a result of sales of our common units owned by Sinclair stockholders or current HEP unitholders. Our unitholders may not realize a benefit commensurate with the ownership dilution they will experience.

- 24 -

•Litigation relating to the Sinclair Transactions could result in substantial costs or an injunction preventing the completion of the HEP Transaction.

Risks Related to Government Regulation

•Our operations are subject to evolving federal, state and local laws, regulations, oversight by governmental agencies and permit/authorization requirements regarding our business, capital projects and environmental protection (including greenhouse gases and climate change protection), health, operational safety and product quality, any of which could result in potential liabilities, increased operating costs, and reduced demand for our services.

Risks Related to Cybersecurity, Data Security and Information Technology

•Cyberattacks, security breaches, information technology system failures, terrorist attacks or global hostilities could have a material adverse effect on our business, financial condition, results of operations or cash flows. We are subject to laws, rules, regulations and policies regarding data privacy and security, and may be subject to additional related laws and regulations in jurisdictions in which we operate or expand.

Risks Related to Liquidity, Financial Instruments and Credit

•We may not be able to retain existing customers or acquire new customers.

•Our leverage or volatile credit/capital markets may limit our ability to borrow funds on acceptable terms, service our indebtedness or capitalize on business opportunities. Increases in interest rates could adversely affect our business. The expected phase out of LIBOR could impact the interest rates paid on our variable rate indebtedness and could cause our interest expense to increase.

•If we are unable to generate sufficient cash flow, our ability to pay quarterly distributions to our common unitholders at current levels or to increase our quarterly distributions in the future could be impaired materially.

•We are exposed to the credit risks and certain other risks, of our or our joint ventures' key customers, vendors, and other counterparties. Adverse changes in our and/or our general partner's credit ratings and risk profile may negatively affect us.

Risks to Common Unitholders

•HFC and its affiliates may have conflicts of interest and limited fiduciary duties, which may permit them to favor their own interests or engage in limited competition with us.

•Cost reimbursements and fees due to our general partner and its affiliates for services provided are substantial. Our general partner may reduce the amount of cash in reserve available for distribution to unitholders. Even if unitholders are dissatisfied, they cannot remove our general partner without its consent. The control of our general partner may be transferred to a third party without unitholder consent.

•We may issue additional limited partner units without unitholder approval, which would dilute an existing unitholder's ownership interests. Our general partner has a limited call right that may require a unitholder to sell its common units at an undesirable time or price.

Tax Risks to Common Unitholders

•Our tax treatment depends on our status as a partnership for U.S. federal income tax purposes, and not being subject to a material amount of entity-level taxation. Our cash available for distribution to unitholders may be substantially reduced if we become subject to entity-level taxation as a result of the Internal Revenue Service (“IRS”) treating us as a corporation or legislative, judicial or administrative changes, and it may also be reduced by any audit adjustments if imposed directly on the partnership.

•Even if unitholders do not receive any cash distributions from us, unitholders will be required to pay taxes on their share of our taxable income. Unitholders may be subject to limitation on their ability to deduct interest expense incurred by us.

•Tax-exempt entities and non-U.S. unitholders face unique tax issues from owning our common units that may result in adverse tax consequences to them. The IRS may challenge certain tax positions, treatment methodologies or allocations, which could adversely affect the value of our common units.

Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also materially and adversely affect our business operations. If any of the following risks were to actually occur, our business, financial condition, results of operations or treatment of unitholders could be materially and adversely affected. The headings provided in this Item 1A. are for convenience and reference purposes only and shall not affect or limit the extent or interpretation of the risk factors.

RISKS RELATED TO OUR BUSINESS/INDUSTRY

We depend on HFC (particularly its Navajo and Woods Cross refineries) for a substantial portion of our revenues; if those revenues were significantly reduced or if HFC's financial condition materially deteriorated, there would be a material adverse effect on our results of operations.

For the year ended December 31, 2021, HFC accounted for 67% of the revenues of our petroleum product and crude pipelines, 88% of the revenues of our terminals, tankage, and truck loading racks, and 100% of the revenue from our refinery processing units. We expect to continue to derive a majority of our revenues from HFC for the foreseeable future. If HFC satisfies only its minimum obligations under the long-term pipeline and terminal, tankage and throughput agreements that it has with us or is unable to meet its minimum annual payment commitment for any reason, including due to prolonged downtime or a shutdown at its refineries, our revenues and cash flow would decline.

Any significant reduction in production at HFC’s Navajo or Woods Cross refineries could reduce throughput in our pipelines, terminals and refinery processing units, resulting in materially lower levels of revenues and cash flow for the duration of the shutdown. For the year ended December 31, 2021, production from HFC's Navajo and Woods Cross refineries accounted for approximately 50% of the throughput volumes transported by our refined product, intermediate and crude pipelines. Our Woods Cross refinery processing units also accounted for 72% of our refinery processing units revenues.

Operations at any of HFC's refineries could be partially or completely shut down, temporarily or permanently, as the result of:

•competition from other refineries and pipelines that may be able to supply the refinery's end-user markets on a more cost-effective basis;

•operational problems such as catastrophic events at the refinery, terrorist or cyberattacks, vandalism, labor difficulties, public health crisis such as COVID-19, or government response thereto, environmental proceedings or other litigation that cause a stoppage of all or a portion of the operations at the refinery;

•planned maintenance or capital projects;

•increasingly stringent environmental laws and regulations, such as the U.S. Environmental Protection Agency's gasoline and diesel sulfur control requirements that limit the concentration of sulfur in motor gasoline and diesel fuel for both on-road and non-road usage as well as various state and federal emission requirements that may affect the refinery itself and potential future climate change regulations;

•an inability to obtain crude oil for the refinery at competitive prices; or

•a general reduction in demand for refined products in the area due to:

◦a local or national recession, public health crisis such as COVID-19, or other adverse event or economic condition that results in lower spending by businesses and consumers on gasoline and diesel fuel;

◦higher gasoline prices due to higher crude oil costs, higher taxes or stricter environmental laws or regulations; or

◦a shift by consumers to more fuel-efficient or alternative fuel vehicles or an increase in fuel efficiency, whether as a result of technological advances by manufacturers, legislation either mandating or encouraging higher fuel efficiency or the increased use of alternative fuel sources or otherwise.

For example, on June 1, 2020, HFC announced plans to permanently cease petroleum refining operations at its Cheyenne refinery and to convert certain assets at that refinery to renewable diesel production. HFC subsequently began winding down petroleum refining operations at its Cheyenne refinery on August 3, 2020.

The effect on us of any shutdown would depend on the length of the shutdown and the extent of the refinery operations affected by the shutdown. We have no control over the factors that may lead to a shutdown or the measures HFC may take in response to a shutdown. HFC makes all decisions at each of its refineries concerning levels of production, regulatory compliance, refinery turnarounds (planned shutdowns of individual process units within the refinery to perform major maintenance activities), labor relations, environmental remediation, emission control and capital expenditures and is responsible for all related costs. HFC is not under contractual obligation to us to maintain operations at its refineries.

Furthermore, HFC's obligations under the long-term pipeline and terminal, tankage, tolling and throughput agreements with us would be temporarily suspended during the occurrence of a force majeure event that renders performance impossible with respect to an asset for at least 30 days. If such an event were to continue for a year, we or HFC could terminate the agreements. The occurrence of any of these events could reduce our revenues and cash flows.

- 26 -

Due to our lack of asset and geographic diversification, an adverse development in our businesses could materially and adversely affect our financial condition, results of operations or cash flows.

A large concentration of our pipeline assets serve HFC's Navajo refinery. Due to our limited asset and geographic diversification, an adverse development in our business (including adverse developments as a result of catastrophic events or weather, terrorist or cyberattacks, vandalism, public health crisis, decreased supply of crude oil and feedstocks and/or decreased demand for refined petroleum products), could have a significantly greater impact on our financial condition, results of operations or cash flows than if we maintained more diverse assets in more diverse locations.

The COVID-19 pandemic or any other widespread outbreak of an illness or pandemic or other public health crisis, and actions taken in response thereto, as well as certain developments in the global oil markets, have had and may continue to have a material adverse effect on our operations, business, financial condition, results of operations or cash flows.

Our business depends in large part on the demand for the various petroleum products we transport, terminal and store in the markets we serve. COVID-19’s spread across the globe and government regulations in response thereto have negatively affected worldwide economic and commercial activity, impacted global demand for oil, gas and refined products, and created significant volatility and disruption of financial and commodity markets. Other factors expected to impact crude oil supply include production levels implemented by OPEC members, other large oil producers such as Russia and domestic and Canadian oil producers. Please see “Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Impact of COVID-19 on Our Business”.

In addition, the volume of crude oil or refined products we transport, terminal or store depends on many other factors outside of our control, some of which include:

•changes in domestic demand for, and the marketability of, refined products, and in turn, for crude oil and its transportation, due to governmental regulations, including travel bans and restrictions, quarantines, shelter in place orders, and shutdowns;

•the ability of HFC, our other customers or our joint ventures’ other customers to fulfill their respective contractual obligations or any material reduction in, or loss of, revenue from our customers or our joint ventures’ customers;

•increased price volatility, including the prices our customers or our joint ventures’ customers pay for crude oil and other raw materials and receive for their refined and finished lubricant products;

•the health of our workforce, including contractors and subcontractors, and their access to our facilities, which could result in a full or partial shutdown of our facilities if a significant portion of the workforce at a facility is impacted or if a significant portion of the workforce in our control room is impacted;

•the availability, distribution and effectiveness of vaccines for COVID-19;

•the ability or willingness of our or our joint ventures’ current vendors and suppliers to provide the equipment or parts for our or our joint ventures’ operations or otherwise fulfill their contractual obligations, potentially causing our delay or failure in construction projects or to deliver crude oil or refined products on a timely basis or at all;

•increased potential for the occurrence of operational hazards, including terrorism, cyberattacks or vandalism, as well as information system failures or communication network disruptions;

•increasing cost and reduced availability of capital for additional liquidity, growth or capital expenditures;

•delay by government authorities in issuing or maintaining permits necessary for our business or our capital projects;

•shareholder activism and activities by non-governmental organizations to limit sources of funding for the energy sector;

•increasing costs of operation in relation to the COVID-19 outbreak, which costs may not be fully recoverable or adequately covered by insurance; and

•the impact of any economic downturn, recession or other disruption of the U.S. and global economies and financial and commodity markets.

Adverse developments in the global economy or in regional economies could also negatively impact our customers and suppliers, and therefore have a negative impact on our business or financial condition. In the event of adverse developments or stagnation in the economy or financial markets, our customers may experience deterioration of their businesses, reduced demand for their products, cash flow shortages and difficulty obtaining financing. As a result, existing or potential customers might delay or cancel plans to use our services and may not be able to fulfill their obligations to us in a timely fashion. Further, suppliers may experience similar conditions, which could impact their ability to fulfill their obligations to us.

The spread of COVID-19 has caused us to modify our business practices (including limiting employee and contractor presence at our work locations and to sequester employees critical to the operation of our control room from time to time as needed), and we may take further actions as may be required by government authorities or that we determine are in the best interests of our employees, contractors, customers, suppliers and communities. There is no certainty that such measures will be sufficient to mitigate the risks posed by the virus, and our ability to perform critical functions could be adversely impacted.

- 27 -

The effects of COVID-19 are difficult to predict and the duration of any potential business disruption or the extent to which it may negatively affect our operating results or our liquidity is uncertain. The extent to which the pandemic will continue to impact our business results and operations remains uncertain in light of the rapidly evolving environment, duration and severity of the spread of the virus, emerging variants, vaccine and booster effectiveness, public acceptance of safety protocols, and government measures, including vaccine mandates, designed to slow and contain the spread of COVID-19, among others, and, all of which are beyond our control. In addition, if the volatility and seasonality in the oil and gas industry were to increase, the demand for our services may decline. We continue to monitor the situation to assess further possible implications to our business and to take actions in an effort to mitigate adverse consequences. These effects of the COVID-19 pandemic, as well as the volatility in global oil markets, while uncertain, have, and may continue to, materially adversely affect our business, financial condition, results of operations and/or cash flows, as well as our ability to pay distributions to our common unitholders.

A material decrease in the supply, or a material increase in the price, of crude oil or other materials available to HFC's refineries and our pipelines and terminals, and a corresponding decrease in demand for refined products in the markets served by our pipelines and terminals, could reduce our revenues materially.

The volume of refined products we transport in our refined product pipelines depends on the level of production of refined products from HFC's refineries, which, in turn, depends on the availability of attractively-priced crude oil produced in the areas accessible to those refineries. In order to maintain or increase production levels at their refineries, our shippers must continually contract for new crude oil supplies. A material decrease in crude oil production from the fields that supply their refineries, as a result of depressed commodity prices, decreased demand, lack of drilling activity, natural production declines, catastrophic events or otherwise, could result in a decline in the volume of crude oil our shippers refine, absent the availability of transported crude oil to offset such declines. Such an event would result in an overall decline in volumes of refined products transported through our pipelines and therefore a corresponding reduction in our cash flow. In addition, the future growth of our shippers' operations will depend in part upon whether our shippers can contract for additional supplies of crude oil at a greater rate than the rate of natural decline in their currently connected supplies.

Fluctuations in crude oil prices can greatly affect production rates and investments by third parties in the development of new oil reserves. Drilling activity generally decreases as crude oil prices decrease. We and our shippers have no control over producers or their production decisions, which are affected by, among other things, prevailing and projected energy prices, demand for hydrocarbons, geological considerations, governmental regulation, global market conditions, actions by foreign nations and the availability and cost of capital, or over the level of drilling activity in the areas of operations, the amount of reserves underlying the wells and the rate at which production from a well will decline. Similarly, a material increase in the price of crude oil supplied to refineries without an increase in the market value of the products produced by the refineries, either temporary or permanent, which causes a reduction in the production of refined products at the refineries, would cause a reduction in the volumes of refined products we transport, and our cash flow could be adversely affected.

In addition, periods of disruption in the global supply chain, including as a result of COVID-19, have caused shortages in the equipment and parts necessary to operate our facilities and to complete our capital projects. Certain suppliers have experienced, and may continue to experience, delays related to a variety of factors, including logistical delays and component shortages from vendors. We continue to monitor the situation and work closely with our suppliers to minimize disruption to our operations as a result of supply chain interruptions.

Finally, our business depends in large part on the demand for the various petroleum products we gather, transport and store in the markets we serve. Reductions in that demand adversely affect our business. Market demand varies based upon the different end uses of the petroleum products we gather, transport and store. We cannot predict the impact of future fuel conservation measures, alternate fuel requirements, government regulation, global pandemic, technological advances in fuel economy and energy-generation devices, exploration and production activities, and actions by foreign nations, any of which could reduce the demand for the petroleum products in the areas we serve.

Competition from other pipelines that may be able to supply our shippers' customers with refined products at a lower price could cause us to reduce our rates or could reduce our revenues.

We and our shippers could face increased competition if other pipelines are able to supply our shippers' end-user markets competitively with refined products. For example, increased supplies of refined product delivered by Kinder Morgan's El Paso to Phoenix pipeline could result in additional downward pressure on wholesale-refined product prices and refined product margins in El Paso and related markets. Additionally, further increases in products from Gulf Coast refiners entering the El Paso and Arizona markets on this and other pipelines and a resulting increase in the demand for shipping product on the interconnecting common carrier pipelines could cause a decline in the demand for refined product from HFC. This could reduce our opportunity to earn revenues from HFC in excess of its minimum volume commitment obligations.

- 28 -

An additional factor that could affect some of HFC's markets is excess pipeline capacity from the West Coast into our shippers' Arizona markets. Additional increases in shipments of refined products from the West Coast into our shippers' Arizona markets could result in additional downward pressure on refined product prices that, if sustained over the long term, could influence product shipments by HFC to these markets.

Any reduction in the capacity of, or the allocations to, our shippers on interconnecting, third-party pipelines could cause a reduction of volumes transported in our pipelines and through our terminals.

HFC and the other users of our pipelines and terminals are dependent upon connections to third-party pipelines to receive and deliver crude oil and refined products. Any reduction of capacities of these interconnecting pipelines due to testing, line repair, reduced operating pressures, catastrophic events, terror or cyberattacks, vandalism or other causes could result in reduced volumes transported in our pipelines or through our terminals. Similarly, if additional shippers begin transporting volumes of refined products over interconnecting pipelines, the allocations to existing shippers in these pipelines would be reduced, which could also reduce volumes transported in our pipelines or through our terminals.

Our business may suffer due to a change in the composition of our Board of Directors, the departure of any of our key senior executives or other key employees who provide services to us, or if certain of our executive officers, who also allocate time to our general partner and its affiliates, do not have enough time to dedicate to our business. Furthermore, a shortage of skilled labor or disruptions in the labor force that provides services to us may make it difficult for us to maintain labor productivity.

Our future performance depends to a significant degree upon the continued contributions of HLS's Board of Directors, key senior executives and key senior employees who provide services to us. Also, our business depends on the continuing ability to recruit, train and retain highly qualified employees in all areas of our operations, including accounting, business operations, finance and other key back-office and mid-office personnel. The competition for these employees is intense, and the loss of these executives or employees could harm our business. If any of these executives or other key personnel resign or become unable to continue in their present roles and are not adequately replaced, our business operations could be materially adversely affected. We do not currently maintain “key person” life insurance for any executives. Furthermore, our operations require skilled and experienced laborers with proficiency in multiple tasks. A shortage of trained workers due to retirements or otherwise could have an adverse impact on productivity and costs, which could adversely affect our operations.

Our general partner shares officers and administrative personnel with HFC to operate both our business and HFC's business. These officers face conflicts regarding the allocation of their and other employees' time, which may affect adversely our results of operations, cash flows and financial condition.

A portion of HFC's employees that are seconded to us from time to time are represented by labor unions under collective bargaining agreements with various expiration dates. HFC may not be able to renegotiate the collective bargaining agreements when they expire on satisfactory terms or at all. A failure to do so may increase our costs. In addition, existing labor agreements may not prevent a future strike or work stoppage, and any work stoppage could negatively affect our results of operations and financial condition.

If we are unable to complete capital projects at their expected costs or in a timely manner, if we incur increased maintenance or repair costs on assets, or if the market conditions assumed in our project economics deteriorate, our financial condition, results of operations, or cash flows could be materially and adversely affected.

Delays or cost increases related to capital spending programs involving construction of new facilities (or improvements and increased maintenance or repair expenditures on our existing facilities) could adversely affect our ability to achieve forecasted operating results. Although we evaluate and monitor each capital spending project and try to anticipate difficulties that may arise, such delays or cost increases may arise as a result of numerous factors, such as:

•third-party challenges to, denials, or delays in issuing requisite regulatory approvals and/or permits;

•societal and political pressures and other forms of opposition;

•compliance with or liability under environmental or pipeline safety regulations;

•unplanned increases in the cost of construction materials or labor;

•disruptions in transportation of modular components and/or construction materials;

•severe adverse weather conditions, natural disasters, terror or cyberattacks, domestic vandalism other events (such as equipment malfunctions, explosions, fires or spills) affecting our facilities, or those of vendors and suppliers;

•shortages of sufficiently skilled labor, or labor disagreements resulting in unplanned work stoppages;

•market-related increases in a project's debt or equity financing costs; and/or

•nonperformance or force majeure by, or disputes with, vendors, suppliers, contractors, or sub-contractors involved with a project.

We may not be able to fully execute our growth strategy if we encounter illiquid capital markets or increased competition for investment opportunities, if our assumptions concerning population growth are inaccurate, or if an agreement cannot be reached with HFC for the acquisition of assets on which we have a right of first offer.

Our strategy contemplates growth through the development and acquisition of crude, intermediate and refined products transportation and storage assets while maintaining a strong balance sheet. This strategy includes constructing and acquiring additional assets and businesses, either from HFC or third parties, to enhance our ability to compete effectively and diversifying our asset portfolio, thereby providing more stable cash flow. We regularly consider and enter into discussions regarding, and are currently contemplating and/or pursuing, potential joint ventures, stand-alone projects or other transactions that we believe will present opportunities to realize synergies, expand our role in our chosen businesses and increase our market position.

We will require substantial new capital to finance the future development and acquisition of assets and businesses. Any limitations on our access to capital will impair our ability to execute this strategy. If the cost of such capital becomes too expensive, or if the development or acquisition opportunities are on terms that do not allow us to obtain appropriate financing, our ability to develop or acquire accretive assets will be limited. We may not be able to raise the necessary funds on satisfactory terms, if at all. The primary factors that influence our cost of equity include market conditions, fees we pay to underwriters and other offering costs, which include amounts we pay for legal and accounting services. The primary factors influencing our cost of borrowing include interest rates, credit spreads, credit ratings, covenants, underwriting or loan origination fees and similar charges we pay to lenders.

In addition, we experience competition for the types of assets and businesses we have historically purchased or acquired. High competition, particularly for a limited pool of assets, may result in higher, less attractive asset prices, and therefore, we may lose to more competitive bidders. Such occurrences limit our ability to execute our growth strategy, which may materially adversely affect our ability to maintain or pay higher distributions in the future.

Our growth strategy also depends upon:

•the accuracy of our assumptions about growth in the markets that we currently serve or have plans to serve in the Southwestern, Northwest and Mid-Continent regions of the United States;

•HFC's willingness and ability to capture a share of additional demand in its existing markets; and

•HFC's willingness and ability to identify and penetrate new markets in the Southwestern, Northwest and Mid-Continent regions of the United States.

If our assumptions about increased market demand prove incorrect, HFC may not have any incentive to increase refinery capacity and production or shift additional throughput to our pipelines, which would adversely affect our growth strategy.

Our Omnibus Agreement with HFC provides us with a right of first offer on certain of HFC’s existing or acquired logistics assets. The consummation and timing of any future acquisitions of these assets will depend upon, among other things, our ability to negotiate acceptable purchase agreements and commercial agreements with respect to the assets and our ability to obtain financing on acceptable terms. We can offer no assurance that we will be able to successfully consummate any future acquisitions pursuant to our right of first offer. In addition, certain of the assets covered by our right of first offer may require substantial capital expenditures in order to maintain compliance with applicable regulatory requirements or otherwise make them suitable for our commercial needs. For these or a variety of other reasons, we may decide not to exercise our right of first offer if and when any assets are offered for sale, and our decision will not be subject to unitholder approval. In addition, our right of first offer may be terminated upon a change of control of HFC.

Our operations are subject to catastrophic losses, operational hazards and unforeseen interruptions for which we may not be adequately insured.

Our operations are subject to catastrophic losses, operational hazards and unforeseen interruptions such as natural disasters, adverse weather, earthquakes, accidents, fires, explosions, hazardous materials releases or spills, terror or cyberattacks, vandalism, power failures, mechanical failures and other events beyond our control. These events could result in an injury, loss of life, or property damage or destruction, as well as a curtailment or interruption in our operations. In addition, third-party damage, mechanical malfunctions, undetected leaks in pipelines, faulty measurement or other errors may result in significant costs or lost revenues.

We may not be able to maintain or obtain insurance of the type and amount we desire at commercially reasonable rates and exclusions from coverage may limit our ability to recover the amount of the full loss in all situations. As a result of market conditions, premiums and deductibles for certain of our insurance policies could increase. In some instances, certain insurance could become unavailable or available only for reduced amounts of coverage.

- 30 -

There can be no assurance that insurance will cover all or any damages and losses resulting from these types of hazards. We are not fully insured against all risks or incidents to our business and therefore, we self-insure certain risks. We are not insured against all environmental accidents that might occur. Our property insurance includes business interruption coverage for lost profit arising from physical damage to our facilities. If a significant accident or event occurs that is self-insured or not fully insured, our operations could be temporarily or permanently impaired, our liabilities and expenses could be significant and it could have a material adverse effect on our financial position. Because our partnership agreement requires us to distribute all available cash (less operating surplus cash reserves) to our unitholders, we do not have the same flexibility as other legal entities to accumulate cash to protect against under insured or uninsured losses.

We could be subject to damages based on claims brought against us by our customers or lose customers as a result of the failure of products we distribute to meet certain quality specifications. In addition, we could be required to make substantial expenditures in the event of any changes in product quality specifications.

A significant portion of our operating responsibility on refined product pipelines is to ensure the quality and purity of the products loaded at our loading racks. If our quality control measures fail, off-specification product could be sent out to public gasoline stations. This type of incident could result in liability claims regarding damages caused by the off-specification fuel or could impact our ability to retain existing customers or to acquire new customers, any of which could have a material adverse impact on our results of operations and cash flows.

In addition, various federal, state and local agencies have the authority to prescribe specific product quality specifications of refined products. Changes in product quality specifications or blending requirements could reduce our throughput volume, require us to incur additional handling costs or require capital expenditures. For example, different product specifications for different markets impact the fungibility of the products in our system and could require the construction of additional storage. If we are unable to recover these costs through increased revenues, our cash flows and ability to pay cash distributions could be adversely affected. In addition, changes in the product quality of the products we receive on our petroleum products pipeline system could reduce or eliminate our ability to blend products.

We do not own all of the land on which our pipeline systems and other assets are located, which could result in disruptions to our operations. Additionally, a change in the regulations related to a state’s use of eminent domain could inhibit our ability to secure rights-of-way for future pipeline construction projects. Finally, certain of our assets are located on or adjacent to Native American tribal lands.

We do not own all of the land on which our pipeline systems and other assets are located, and we are, therefore, subject to the risk of increased costs or more burdensome terms to maintain necessary land use. We obtain the right to construct and operate pipelines and other assets on land owned by third parties and government agencies for specified periods. If we were to lose these rights through an inability to renew leases, right-of-way contracts or similar agreements, we may be required to relocate our pipelines or other assets and our business could be adversely affected. Additionally, it may become more expensive for us to obtain new rights-of-way or leases or to renew existing rights-of-way or leases. If the cost of obtaining or renewing such agreements increases, it may adversely affect our operations and the cash flows available for distribution to unitholders.

The adoption or amendment of laws and regulations that limit or eliminate a state’s ability to exercise eminent domain over private property in a state in which we operate could make it more difficult or costly for us to secure rights-of-way for future pipeline construction and other projects.

Certain of our pipelines are located on or adjacent to Native American tribal lands. Various federal agencies, along with each Native American tribe, promulgate and enforce regulations, including environmental standards, regarding operations on Native American tribal lands. In addition, each Native American tribe is a sovereign nation having the right to enforce laws and regulations (including various taxes, fees, and other requirements and conditions) and to grant approvals independent from federal, state and local statutes and regulations. Following a decision issued in May 2017 by the federal Tenth Circuit Court of Appeals, tribal ownership of even a very small fractional interest in an allotted land, that is, tribal land owned or at one time owned by an individual Native American landowner, bars condemnation of any interest in the allotment. Consequently, the inability to condemn such allotted lands under circumstances where existing pipeline rights-of-way may soon lapse or terminate serves as an additional impediment for pipeline operations. Separately, in 2020, the Supreme Court ruled in McGirt v. Oklahoma that the Muscogee (Creek) Nation reservation in Eastern Oklahoma has not been disestablished, and several state courts have subsequently used the analysis therein to find that other reservations in the state have not been disestablished. Although the ruling in McGirt indicates that it is limited to criminal law, the ruling has significant potential implications for civil law. At this time, we cannot predict how these jurisdictional issues may ultimately be resolved. These factors may increase our cost of doing business on Native American tribal lands.

In addition, our industry is subject to potentially disruptive activities by those concerned with the possible environmental impacts of pipeline routes. Activists, non-governmental organizations and others may seek to restrict the transportation of crude oil and refined products by exerting social or political pressure to influence when, and whether, such rights-of-way or permits

- 31 -

are granted. This interference could impact future pipeline development, which could interfere with or block expansion or development projects and could have a material adverse effect on our business, financial condition, results of operations and our ability to make cash distributions to our unitholders.

Terrorist attacks, and the threat of terrorist attacks or vandalism, have resulted in increased costs to our business. Global hostilities may adversely impact our results of operations.

The long-term impact of (and threat of future) terrorist attacks and vandalism, on the energy transportation industry in general, and on us in particular, is unknown. Any attack on our facilities, those of our customers and, in some cases, those of other pipelines could have a material adverse effect on our business. Increased security measures taken by us as a precaution against possible terrorist attacks or vandalism have resulted in increased costs to our business.

The U.S. government has issued public warnings that indicate that pipelines and other assets might be specific targets of terrorist organizations. These potential targets might include our pipeline systems or operating systems and may affect our ability to operate or control our pipeline assets or our operations could be disrupted. The occurrence of one of these events could cause a substantial decrease in revenues, increased costs to respond or other financial loss, damage to reputation, increased regulation or litigation and or inaccurate information reported from our operations. These developments may subject our operations to increased risks, as well as increased costs, and, depending on their ultimate magnitude, could have a material adverse effect on our business, results of operations and financial condition.

Uncertainty surrounding global hostilities or other sustained military campaigns, and the possibility that infrastructure facilities could be direct targets of, or indirect casualties of, an act of terror, may affect our operations in unpredictable ways, including disruptions of crude oil supplies and markets for refined products or instability in the financial markets that could restrict our ability to raise capital.

In addition, changes in the insurance markets attributable to terrorist attacks, vandalism, or cyberattacks or extortion could make certain types of insurance more difficult for us to obtain. Moreover, the insurance that may be available to us may be significantly more expensive than our existing insurance coverage. Instability in the financial markets as a result of terrorism, cyberattacks, vandalism or war could also affect our ability to raise capital, including our ability to repay or refinance debt.

We own certain of our systems through joint ventures, and our control of such systems is limited by provisions of the agreements we have entered into with our joint venture partners and by our percentage ownership in such joint ventures.

Although our subsidiary is the operator of the UNEV pipeline and we own a majority interest in the joint venture that owns the UNEV pipeline, the joint venture agreement for the UNEV pipeline generally requires consent of our joint venture partner(s) for specified extraordinary transactions, such as reversing the flow of the pipeline or increasing the fees paid to our subsidiary pursuant to the operating agreement.

In addition, certain of our systems are operated by joint venture entities for which we do not serve as the operator, or in which we do not have an ownership stake that permits us to control the business activities of the entity. We have limited ability to influence the business decisions of such joint venture entities.

Because we have partial ownership in the joint ventures, we may be unable to control the amount of cash we will need for capital projects or will receive from the operation and could be required to contribute significant cash to fund our share of their projects and operations, which could adversely affect our ability to distribute cash to our unitholders.

An impairment of our long-lived assets or goodwill could reduce our earnings or negatively impact our financial condition and results of operations.

An impairment of our long-lived assets or goodwill could reduce our earnings or negatively impact our results of operations and financial condition. We continually monitor our business, the business environment and the performance of our operations to determine if an event has occurred that indicates that a long-lived asset or goodwill may be impaired. If a triggering event occurs, which is a determination that involves judgment, we may be required to utilize cash flow projections to assess our ability to recover the carrying value based on the ability to generate future cash flows. We may also conduct impairment testing based on both the guideline public company and guideline transaction methods. Our long-lived assets and goodwill impairment analyses are sensitive to changes in key assumptions used in our analysis, estimates of future tariff rates, forecasted throughput levels, operating costs and capital expenditures. If the assumptions used in our analysis are not realized, it is possible a material impairment charge may need to be recorded in the future. We cannot accurately predict the amount and timing of any additional impairments of long-lived assets or goodwill in the future.

- 32 -

During the years ended December 31, 2021 and December 31, 2020, we recorded a goodwill impairment charge of $11.0 million and $35.7 million, respectively, related to our Cheyenne reporting unit. A reasonable expectation exists that further deterioration in our operating results or overall economic conditions could result in an impairment of goodwill and/or additional long-lived asset impairments at some point in the future. Future impairment charges could be material to our results of operations.

Growing our business by constructing new pipelines and terminals, or expanding existing ones, subjects us to construction risks.

One of the ways we may grow our business is through the construction of new pipelines and terminals or the expansion of existing ones. The construction of a new pipeline or the expansion of an existing pipeline, by adding horsepower or pump stations or by adding a second pipeline along an existing pipeline, involves numerous regulatory, environmental, political, and legal uncertainties, most of which are beyond our control. For example, the Biden Administration has temporarily suspended the grant of certain authorizations for oil and gas activities on federal lands, although this does not affect existing authorizations. Pipeline construction projects requiring federal approvals are generally subject to environmental review requirements under the National Environmental Policy Act, and must also comply with other natural resource review requirements imposed pursuant to the Endangered Species Act and the National Historic Preservation Act. For over 35 years, the Corps has authorized construction, maintenance, and repair of pipelines under a streamlined Nationwide Permit (“NWP”) program; however, in April 2020, the U.S. District Court for the District of Montana determined that NWP 12 failed to comply with consultation requirements under the federal Endangered Species Act, vacated NWP 12, and enjoined the issuance of new authorizations for oil and gas pipeline projects under NWP 12. While the district court’s order has subsequently been limited pending appeal, we cannot predict the ultimate outcome of this case. Additionally, in response to the vacatur, the Corps has announced a reissuance of the NWP 12 for oil and natural gas pipeline activities, including certain revisions to the conditions for the use of NWP 12; however, the rulemaking may be subject to litigation or to further revision under the Biden Administration. While the full extent and impact of the vacatur is unclear at this time, we could face significant delays and financial costs if we must obtain individual permit coverage from the Corps for our projects. These projects may not be completed on schedule (or at all) or at the budgeted cost. In addition, our revenues may not increase immediately upon the expenditure of funds on a particular project. For instance, if we build a new pipeline, the construction will occur over an extended period of time and we will not receive any material increases in revenues until after completion of the project.

Moreover, we may construct facilities to capture anticipated future growth in demand for refined products in a region in which such growth does not materialize. As a result, new facilities may not be able to attract enough throughput to achieve our expected investment return, which could adversely affect our earnings, results of operations and financial condition.

RISKS RELATED TO OUR ACQUISITION STRATEGY AND RECENT/PENDING ACQUISITIONS

We may be unsuccessful in integrating the operations of the assets we have acquired or may acquire with our operations, and in realizing all or any part of the anticipated benefits of any such acquisitions.

From time to time, we evaluate and acquire assets and businesses that we believe complement our existing assets and businesses. Acquisitions may require substantial capital or the incurrence of substantial indebtedness. Our capitalization and results of operations may change significantly as a result of completed or future acquisitions. Acquisitions and business expansions involve numerous risks, including difficulties in the assimilation of the assets and operations of the acquired businesses, inefficiencies and difficulties that arise because of unfamiliarity with new assets and the businesses associated with them, and new geographic areas and the diversion of management's attention from other business concerns. Further, unexpected costs and challenges may arise whenever businesses with different operations or management are combined, and we may experience unanticipated delays in realizing the benefits of an acquisition. Also, following an acquisition, we may discover previously unknown liabilities associated with the acquired business or assets for which we have no recourse under applicable indemnification provisions.

The pending Sinclair Transactions may not be consummated on a timely basis or at all. Failure to complete the acquisition within the expected timeframe or at all could adversely affect our common unit price and our future business and financial results.

On August 2, 2021, we entered into the Contribution Agreement with Sinclair and certain other parties thereto to acquire all of the issued and outstanding capital stock of STC. We expect the Sinclair Transactions to close in 2022. The Sinclair Transactions are subject to closing conditions. If these conditions are not satisfied or waived, the Sinclair Transactions will not be consummated. If the closing of the Sinclair Transactions is substantially delayed or does not occur at all, or if the terms of the acquisition are required to be modified substantially, we may not realize the anticipated benefits of the acquisition fully or at all, or they may take longer to realize than expected. The closing conditions include, among others, the absence of a law or order

- 33 -

prohibiting the transactions contemplated by the Business Combination Agreement and the termination or expiration of any waiting periods under the Hart-Scott Rodino Act, as amended (the “HSR Act”), with respect to the Sinclair Transactions. On August 23, 2021, each of HFC and Sinclair filed its respective premerger notification and report regarding the Sinclair Transactions with the U.S. Department of Justice and the U.S. Federal Trade Commission (the “FTC”) under the HSR Act. On September 22, 2021, HFC and Sinclair each received a request for additional information and documentary material (“Second Request”) from the FTC in connection with the FTC’s review of the Sinclair Transactions. Issuance of the Second Request extends the waiting period under the HSR Act until 30 days after both HFC and Sinclair have substantially complied with the Second Request, unless the waiting period is terminated earlier by the FTC or the parties otherwise commit not to close the Sinclair Transactions for some additional period of time. HFC and Sinclair are cooperating with the FTC staff in its review and are working diligently to satisfy the closing conditions as soon as possible. We have incurred and will continue to incur substantial transaction costs whether or not the Sinclair Transactions are completed. Any failure to complete the Sinclair Transactions could have a material adverse effect on our common unit price, our competitiveness and reputation in the marketplace, and our future business and financial results, including our ability to execute on our strategy to return capital to our unitholders.

In order to complete the Sinclair Transactions, HFC and Sinclair must obtain certain governmental approvals, and if such approvals are not granted or are granted with conditions that become applicable to the parties, completion of the transactions may be jeopardized or prevented or the anticipated benefits of the transactions could be reduced.

Completion of the Sinclair Transactions is conditioned upon the expiration or termination of the waiting period relating to the Sinclair Transactions under the HSR Act. Although HFC, HEP and Sinclair have agreed in the Business Combination Agreement and Contribution Agreement to use their reasonable best efforts, subject to certain limitations, to make the necessary filings under the HSR Act and obtain the required governmental approvals, there can be no assurance that the relevant waiting period will expire or terminate and no assurance that the Sinclair Transactions will be completed. In addition, the FTC has broad discretion in administering the governing laws and regulations, and may take into account various facts and circumstances in their consideration of the Sinclair Transactions, including other potential transactions in the oil and gas industry or other industries. The FTC may be affected by government shutdowns, which could result in delays regarding any potential approvals or other actions. The FTC may initiate proceedings seeking to prevent, or otherwise seek to prevent, the Sinclair Transactions. As a condition to the approval of the Sinclair Transactions, the FTC may also impose requirements, limitations or costs, require divestitures or place restrictions on the conduct of the parties’ business after completion of the Sinclair Transactions. Under the terms of the Business Combination Agreement and Contribution Agreement, HFC and HEP are obligated to use reasonable best efforts to complete the transactions, but are not required to take any actions or agree to any terms or conditions in connection with obtaining any regulatory approvals for completing the Sinclair Transactions beyond those specifically described in the Business Combination Agreement and Contribution Agreement.

In the Contribution Agreement, HEP and Sinclair agreed that the consideration to be paid by HEP to Sinclair in connection with the HEP Transaction would be adjusted downward if, as a condition to obtaining antitrust clearance for the Sinclair Transactions, the FTC requires HEP to divest a portion of its equity interest in UNEV and the sales price for such interests does not exceed the threshold provided in the Contribution Agreement. In the Business Combination Agreement, HFC and Sinclair agreed that the stock consideration to be issued to Sinclair would be reduced if, as a condition to obtaining antitrust clearance for the Sinclair Transactions, the FTC requires HFC to divest its refinery in Davis County, Utah (the “Woods Cross Refinery”) and certain related assets and the sales price for such assets does not exceed a threshold provided in the Business Combination Agreement. In addition, HEP and HFC entered into a Letter Agreement (“Letter Agreement”), which provides that if, as a condition to obtaining antitrust clearance for the Sinclair Transactions, HFC enters into a definitive agreement to divest the Woods Cross Refinery, then HEP would sell certain assets located at, or relating to, the Woods Cross Refinery to HFC in exchange for cash consideration equal to $232.5 million plus the certain accounts receivable of HEP in respect of such assets, with such sale to be effective immediately prior to the closing of the sale of the Woods Cross Refinery by HFC. The Letter Agreement also provides that HEP’s right to future revenues from HFC in respect of such Woods Cross Refinery assets will terminate at the closing of such sale. If as a condition to the approval of the Sinclair Transactions the FTC requires HFC and HEP to divest the assets specified in the Business Combination Agreement, Contribution Agreement and Letter Agreement, the cash flows relating to the divested assets would also be lost, the anticipated benefits of the Sinclair Transactions would be reduced and the combined company’s financial position, results of operations and cash flows may be materially and adversely affected.

However, notwithstanding the provisions of the Business Combination Agreement and Contribution Agreement, HFC, HEP or Sinclair could agree to become subject to terms or conditions beyond those required in the Business Combination Agreement and Contribution Agreement in connection with the expiration or termination of such waiting period, the imposition of which could adversely affect HFC’s and HEP’s ability to integrate Sinclair’s operations with their operations, reduce the anticipated benefits of the transactions or otherwise materially and adversely affect the combined company’s financial position, results of operations and cash flows after completion of the transactions.

- 34 -

The actual value of the consideration we will pay to Sinclair at closing may exceed the value allocated to such consideration at the time we entered into the Contribution Agreement.

Under the Contribution Agreement, at closing, we will pay Sinclair a cash payment of $325 million and issue Sinclair 21 million common units, which represents a transaction value of approximately $758 million based on the closing price of our common units as of July 30, 2021. Neither we nor the Sinclair stockholders are permitted to “walk away” from the transaction solely because of changes in the market price of our common units between the signing of the Contribution Agreement and the closing. Our common units have historically experienced volatility. Common unit price changes may result from a variety of factors that are beyond our control, including changes in our business, operations and prospects, regulatory considerations and general market and economic conditions. The closing price of our common units on the New York Stock Exchange on July 30, 2021, was $20.60; and on February 18, 2022, the closing price of our common units was $17.69. The value of the common units we issue in connection with the closing of the Sinclair Transactions may be significantly higher at the closing than when we entered into the Contribution Agreement.

We will issue a large number of common units in connection with the Sinclair Transactions, which will result in dilution to our existing unitholders and may cause the market price of our common units to decline in the future as the result of sales of our common units owned by Sinclair stockholders or current HEP unitholders. Our unitholders may not realize a benefit from the Sinclair Transactions commensurate with the ownership dilution they will experience.

At the closing of the Sinclair Transactions, we will issue 21 million common units to Sinclair. Our issuance of such common units will result in dilution of our existing unitholders’ ownership interests and may also have an adverse impact on our net income per unit in fiscal periods that include (or follow) the closing. The Unitholders Agreement (the “Unitholders Agreement”) between HEP, its ultimate general partner, certain other parties, and the stockholders of Sinclair (the “Sinclair Parties”) also subjects 15.75 million of the HEP common units issued to the Sinclair Parties (the “Restricted Units”) to a “lock-up” period commencing on the closing date, during which the Sinclair Parties will be prohibited from selling the Restricted Units, except for certain permitted transfers. One-third of such Restricted Units will be released from such restrictions on the date that is six months after the closing date, one-third of the Restricted Units will be released from such restrictions on the first anniversary of the closing date, and the remainder will be released from such restrictions on the date that is 15 months from the closing date. In addition, the Unitholders Agreement contains customary registration rights, requiring us to file, within five business days following the closing date, a shelf registration statement on Form S-3 under the Securities Act, to permit the public resale of all the registrable securities held by the Sinclair Parties once such securities are no longer subject to a lock-up.

Following their receipt of common units as consideration in the HEP Transaction, subject to release from the associated lock-up provisions and the filing of a resale registration statement or satisfaction of the requirements of Rule 144, the Sinclair Parties may seek to sell the common units delivered to them. Other HEP unitholders may also seek to sell our common units held by them following, or in anticipation of, completion of the HEP Transaction. These sales (or the perception that these sales may occur), coupled with the increase in the outstanding number of common units, may affect the market for, and the market price of, our common units in an adverse manner.

If we are unable to realize the strategic and financial benefits currently anticipated from the Sinclair Transactions, our unitholders will have experienced dilution of their ownership interest without receiving commensurate benefit, and we may be unable to execute on our strategy to return capital to our unitholders that was described in our press release and investor presentation announcing the Sinclair Transactions.

Litigation relating to the Sinclair Transactions could result in substantial costs to HEP or an injunction preventing the completion of the Sinclair Transactions.

Securities class action lawsuits, derivative and related lawsuits are often brought against public companies that have entered into acquisition, merger or other business combination agreements. Even if such a lawsuit is without merit, defending against these claims can result in substantial costs and divert the time and resources of management. An adverse judgment could result in monetary damages, which could have a negative impact on HEP’s liquidity and financial condition.

Lawsuits that may be brought against us and/or our directors, or have been or may be brought against HFC and/or HFC’s directors, could also seek, among other things, injunctive relief or other equitable relief, including a request to rescind parts of the acquisition agreement already implemented, issue additional disclosures and to otherwise enjoin the parties from consummating the Sinclair Transactions. HFC and the members of HFC’s board of directors were named as defendants in a lawsuit filed in Harris County, Texas, brought by an alleged HFC shareholder challenging the Sinclair Transactions and seeking, among other things, injunctive relief to enjoin and/or rescind the acquisition agreement and require the defendants to amend the related proxy statement, declare a breach of fiduciary duties, provide correct and complete disclosures (or enjoin or unwind the acquisition and share issuance if they do not), rescissory and compensatory damages, and interest, attorney’s fees and other costs. Seven additional lawsuits were filed in federal courts on behalf of individual alleged HFC shareholders: Gerald Lovoi v. HollyFrontier Corp., et al., Case No. 1:21-cv-08805 (S.D.N.Y.); Jared Abrams v. HollyFrontier Corp., et al., Case No. 1:21-cv-09309 (S.D.N.Y.); Christopher Quayle v. HollyFrontier Corp., et al., Case No. 1:21-cv-03079 (D. Colo.); Shannon

Jenkins v. HollyFrontier Corp., et al., Case No. 1:21-cv-09497 (S.D.N.Y.); William Bancroft v. HollyFrontier Corp., et al., Case No. 1:21-cv-09878 (S.D.N.Y.); Stanley Jacobs v. HollyFrontier Corp., et al., Case No. 1:21-cv-01668 (D. Del.); and Timothy Dolan v. HollyFrontier Corp., et al., Case No. 1:21-cv-01670 (D. Del.). All asserted claims under Section 14(a) of the Securities Exchange Act of 1934 (the “Exchange Act”) and SEC Rule 14a-9 and claims under Section 20(a) of the Exchange Act against HFC and the members of HFC’s board of directors, and seek, among other things, to enjoin and/or rescind the acquisition agreement and require defendants to amend the related proxy statement, and, if they do not, to recover damages. Additional lawsuits in connection with the Sinclair acquisition may be filed in the future in federal or state courts.

HFC believes that the lawsuits described above are without merit, and that no further disclosure was required under applicable law. However, HFC made supplemental disclosures on November 30, 2021 to reduce the risk that the lawsuits may delay or otherwise adversely affect the consummation of the Acquisition and to minimize the expense of defending such action. HFC entered into a Settlement Agreement with the plaintiff in the lawsuit filed in Harris County, Texas and the lawsuit was voluntarily dismissed with prejudice. Since the HFC shareholder vote on December 8, 2021, five of the lawsuits filed in federal courts have also been voluntarily dismissed: Bancroft v. HollyFrontier Corp. was voluntarily dismissed on December 13, 2021; Quayle v. HollyFrontier Corp. was voluntarily dismissed on December 21, 2021; Lovoi v. HollyFrontier Corp. was voluntarily dismissed on January 7, 2022; Abrams v. HollyFrontier Corp. was voluntarily dismissed on January 7, 2022; and Jenkins v. HollyFrontier Corp. was voluntarily dismissed on January 25, 2022. With respect to the two outstanding lawsuits, HFC’s additional disclosures moot the claims therein.

The outcome of the remaining lawsuits or any other lawsuit that may be filed challenging the Sinclair Transactions is uncertain. One of the conditions to the closing of the Sinclair Transactions is that no injunction by any court or other tribunal of competent jurisdiction has been entered and continues to be in effect and no law has been adopted or is effective, in either case, that prohibits or makes illegal the closing of the Sinclair Transactions. Consequently, if a plaintiff is successful in obtaining an injunction prohibiting completion of the Sinclair Transactions that injunction may delay or prevent the Sinclair Transactions from being completed within the expected timeframe or at all, which could result in substantial costs to us and may adversely affect our business, financial position, results of operations and cash flows. Relatedly, the defense or settlement of any lawsuit or claim that remains unresolved at the time the Sinclair Transactions are completed may adversely affect our business, financial condition, results of operations and cash flows and result in substantial costs to us.

The HEP Transaction will require management to devote significant attention and resources to integrating the Sinclair business with our business.

The HEP Transaction will require management to devote significant attention and resources to integrating the Sinclair business with our business. Potential difficulties that may be encountered in the integration process include, among others:

•the inability to successfully integrate the Sinclair business into the HEP business in a manner that permits us to achieve the revenue and cost savings that we announced as anticipated from the acquisition;

•complexities associated with managing the larger, integrated business;

•potential unknown liabilities and unforeseen expenses, delays or regulatory conditions associated with the acquisition;

•integrating personnel from the two companies while maintaining focus on providing consistent, high-quality products and services;

•loss of key employees;

•integrating relationships with customers, vendors and business partners;

•performance shortfalls at one or both of the companies as a result of the diversion of management’s attention caused by completing the acquisition and integrating Sinclair’s operations into HEP; and

•the disruption of, or the loss of momentum in, each company’s ongoing business or inconsistencies in standards, controls, procedures and policies.

Delays or difficulties in the integration process could adversely affect our business, financial results, financial condition and common unit price. Even if we are able to integrate our business operations successfully, there can be no assurance that this integration will result in the realization of the full benefits of synergies, cost savings, innovation and operational efficiencies that we currently expect or have communicated from this integration or that these benefits will be achieved within the anticipated time frame.

RISKS RELATED TO GOVERNMENT REGULATION

Our operations are subject to evolving federal, state and local laws, regulations and permit/authorization requirements regarding our business, capital projects and environmental protection, health, operational safety and product quality. Potential liabilities arising from these laws, regulations and requirements could affect our operations and have a material adverse effect on our business.

Our pipelines and terminal, tankage and loading rack operations are subject to increasingly stringent federal, state, and local laws, regulations and oversight regarding, among other things, the generation, storage, handling, use, transportation and distribution of petroleum and hazardous substances by pipeline, truck, rail, ship and barge, the emission and discharge of

- 36 -

materials into the environment, waste management, and characteristics and composition of gasoline and diesel fuels, and other matters otherwise relating to the protection of human health and the environment.

Environmental laws and regulations have raised operating costs for the oil and refined products industry, and compliance with such laws and regulations may cause us, the HFC refineries, and other refineries that we support to incur potentially material expenditures associated with the construction, maintenance, and upgrading of equipment and facilities. Future environmental, health and safety requirements (or changed interpretations of existing requirements), may impose new and/or more stringent requirements on our assets and operations and require us to incur potentially material expenditures to comply. Failure to comply with any applicable laws, regulations, and requirements of regulatory authorities could subject us to substantial penalties and fines.

Our operations require numerous authorizations and permits under various laws and regulations, including environmental and worker health and safety laws and regulations. These authorizations and permits are subject to revocation, renewal, modification, or third-party challenge, and can require operational changes that may involve significant costs to limit impacts or potential impacts on the environment and/or worker health and safety. For example, in May 2015, the EPA published a greatly expanded definition of “waters of the United States” (“WOTUS”) under the federal Clean Water Act (“CWA”) and the jurisdiction of the Corps. Many courts blocked this rule from going into effect, and the EPA and Corps rescinded the WOTUS rule in September 2019. On January 23, 2020, the EPA and the Corps finalized the Navigable Waters Protection Rule, which narrowed the definition of WOTUS relative to the prior 2015 rulemaking and became effective on June 22, 2020, but some courts have blocked this rule as well. The EPA and the Corps are no longer implementing the Navigable Waters Protection Rule and are instead enforcing the WOTUS definition as it was promulgated in 1986. The government is also proposing a rule that would formally rescind the Navigable Waters Protection Rule and, again, greatly expand the definition of WOTUS. Any increase in scope could result in increased costs and delays with respect to obtaining permits for dredge and fill activities in wetland areas. A violation of authorization or permit conditions or other legal or regulatory requirements could result in substantial fines, criminal sanctions, permit revocations and injunctions prohibiting our operations. In addition, major modifications of our operations could require modifications to our existing permits or expensive upgrades to our existing pollution control equipment that could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We may also be required to address conditions that require environmental response actions or remediation. The transportation and storage of refined products produces a risk that refined products and other hydrocarbons may be suddenly or gradually released into the environment, potentially causing substantial expenditures for a response action, significant government penalties, liability to government agencies for natural resources damages, personal injury or property damages to private parties and significant business interruption. Further, we own or lease a number of properties that have been used to store or distribute refined products for many years. Many of these properties have also been operated by third parties whose handling, disposal, or release of hydrocarbons and other wastes were not under our control. Environmental laws can impose strict, joint and several liability for releases of oil and hazardous substances into the environment, and we could be held liable for past releases caused by third parties. If we were to incur a significant liability pursuant to environmental laws or regulations, it could have a material adverse effect on us.

Our operations are also subject to various laws and regulations relating to occupational health and safety. We maintain safety, training and maintenance programs as part of our ongoing efforts to comply with applicable laws and regulations but cannot guarantee that these efforts will always be successful. Compliance with applicable health and safety laws and regulations has required and continues to require substantial expenditures. Failure to appropriately manage occupational health and safety risks associated with our business could also adversely impact our employees, communities, reputation and results of operations.

We may incur significant costs and liabilities resulting from performance of pipeline integrity programs and related repairs.

We are regulated under federal pipeline safety statutes by DOT through the Pipeline and Hazardous Materials Safety Administration (“PHMSA”). PHMSA sets and enforces pipeline safety regulations. Failure to comply with PHMSA or comparable state pipeline safety regulations could result in a number of consequences which may have a materially adverse effect on our operations. PHMSA’s enforcement authority includes the ability to assess civil penalties for violations of pipeline safety regulations, issue orders directing compliance, and issue orders directing corrective action to abate hazardous conditions. Among other things, pipeline safety laws and regulations require pipeline operators to develop integrity management programs, including more frequent inspections and other measures for pipelines located in “high consequence areas,” which are areas where a release could have the most significant adverse consequences, including certain population areas, certain drinking water sources and unusually sensitive ecological areas. These regulations require operators of covered pipelines to perform a variety of heightened assessment, analysis, prevention and repair activities. Routine assessments under the integrity management program may result in findings that require repairs or other actions.

Moreover, changes to pipeline safety laws by Congress and regulations by PHMSA or states that result in more stringent or costly pipeline integrity management or safety standards could possibly have a substantial effect on us and similarly situated

- 37 -

midstream operators. In December 2020, Congress passed the PIPES Act, some elements of which could affect our operations. The Safety of Hazardous Liquid Pipelines final rule (effective July 1, 2020) expands PHMSA’s regulation of the safety of hazardous liquid pipelines by extending reporting requirements to certain hazardous liquid gravity pipelines and rural gathering pipelines, establishing additional integrity management requirements for hazardous liquid pipelines that could affect high consequence areas, adding new assessment and integrity requirements for certain other hazardous liquid pipelines, and expanding various inspection and leak detection requirements. These final rules are expected to result in additional operations and maintenance costs in the coming years.

Rate regulation, changes to rate-making rules, or a successful challenge to the rates we charge on our pipeline systems may reduce our revenues and the amount of cash we generate.

Some of our pipelines are considered interstate common carrier pipelines subject to regulation by the Federal Energy Regulatory Commission (“FERC”) under the Interstate Commerce Act (“ICA”). The ICA requires that the rates charged for transportation on oil pipelines, a category that includes crude oil and petroleum product pipelines, be “just and reasonable” and not unduly discriminatory. The FERC regulations implementing the ICA further require the rates and rules for transportation service on our oil pipelines be filed with the FERC. The ICA permits interested persons to challenge newly proposed or changed rates and authorizes the FERC to suspend the effectiveness of such proposed rates for a period of up to seven months and to investigate such rates. If, upon completion of an investigation, the FERC finds that the proposed rate is unlawful, it is authorized to require the carrier to refund the revenues in excess of the prior tariff collected during the pendency of the investigation. The FERC also may investigate, upon complaint or on its own motion, rates that are already in effect and may order a carrier to change its rates prospectively. Upon an appropriate showing, a shipper may obtain reparations for damages sustained during the two years prior to the filing of a complaint.

Oil pipeline carriers may change their rates in accordance with a FERC-approved indexing methodology, which allows oil pipeline carriers to charge rates up to a prescribed ceiling level that changes annually based on the year-to-year change in the U.S. Producer Price Index for Finished Goods (“PPI”). Shippers may protest rate increases made within the ceiling levels, but such protests must show that the portion of the rate increase resulting from application of the index is substantially in excess of the pipeline’s increase in costs from the previous year. Oil pipeline carriers, as a general rule, utilize this indexing methodology to change their rates.

On December 17, 2020, the FERC established a new price index for the five-year period commencing July 1, 2021 and ending June 30, 2026, in which common carriers charging indexed rates are permitted to adjust their indexed ceilings annually by the PPI plus 0.78%. The FERC received requests for rehearing of its December 17, 2020 order. On January 20, 2022, the FERC issued an order granting rehearing requests and reduced the index to PPI minus 0.21%. As a result, the FERC directed oil pipeline carriers to, by March 1, 2022, reduce rates not subject to agreement between such pipeline and a shipper that would be above the new indexed rate ceiling. Such reduced rates will be in effect from March 1, 2022 until July 1, 2022. Prior to June 1, 2022, the FERC will issue a revised index, which could be positive or negative. Rates reflecting this revised index will become effective on July 1, 2022.

Cost-of-service ratemaking, market-based rates and settlement rates are alternatives to the indexing approach and may be used in certain specified circumstances to change rates. However, these methodologies could limit an oil pipeline carrier’s ability to set rates based on actual costs or may delay implementation of any proposed increase in rates. Adverse decisions by the FERC in approving our oil pipelines’ rates could adversely affect our financial position, results of operations and cash flows.

In addition to maintaining rules and rates on file at FERC for interstate movements, we are also required to maintain rates on file with certain state regulatory authorities for intrastate movements on our petroleum products and crude oil pipelines. Tariff rates for some of our intrastate pipeline services may be subject to challenge by complaint by interested parties or by the independent action of the state regulatory authorities who have jurisdiction over our intrastate pipelines rates.

The profitability of our regulated pipelines is influenced by fluctuations in costs and our ability to recover any increases in our costs in the rates charged to our shippers. To the extent that our costs increase in an amount greater than what we are permitted by the FERC or state regulatory authorities to recover in our rates, or to the extent that there is a lag before we can file for and obtain rate increases, such events can have a negative impact on our operating results. In addition, the FERC, state regulatory authorities, or our customers could initiate proceedings or file complaints challenging the tariff rates charged by our pipelines, which could have an adverse impact on us. HFC and other third party shippers have agreed not to challenge, or to cause others to challenge or assist others in challenging, our tariff rates in effect during the terms of their respective pipelines and terminals agreements; however, other current or future shippers may still challenge our tariff rates. Finally, FERC and state regulatory authorities periodically implement new rules, regulations, and policies that may adversely affect our terms and conditions of service as well as the rates charged for our services or our costs of operation. Failure to comply with the FERC’s regulations and applicable governing statutes could result in civil penalty liability of up to approximately $14,536 per violation per day.

There are various risks associated with greenhouse gases, climate change legislation or regulations, and increasing societal expectations that companies address climate change that could result in increased operating costs, reduced demand for our services and reduced access to capital markets.

Climate change continues to attract considerable attention in the United States. Numerous proposals have been made and could continue to be made at the national, regional and state levels of government to monitor and limit existing emissions of greenhouse gases (“GHGs”) as well as to limit or eliminate future emissions. In 2021, President Biden issued several executive orders that committed to substantial action on climate change and called for, among other things, the increased use of zero-emission vehicles by the federal government, the elimination of subsidies provided to the fossil fuel industry, and increased emphasis on climate-related risk across governmental agencies and economic sectors. As a result, our operations, and those of our customers, are subject to a series of regulatory, political, litigation, and financial risks associated with the transport of fossil fuels and emission of GHGs.

The EPA has adopted rules that, among other things, establish construction and operating permit reviews for GHG emissions from certain large stationary sources, require the monitoring and annual reporting of GHG emissions from certain petroleum and natural gas sources in the United States or require control or reduction of emissions of GHGs, including methane, from such sources. In 2021, the EPA announced its intent to reconsider and revise these rules to further reduce GHG emissions and issued a proposed rule that would extend to existing petroleum and natural gas sources. In addition, the EPA, together with the DOT, implemented GHG emission and corporate average fuel economy standards for vehicles manufactured in the United States, which were revised in December 2021 to impose more stringent requirements for emissions reductions. These and other federal efforts to reduce GHG emissions from the transportation sector could increase our operating costs or reduce demand for our customers’ products.

Internationally, the United Nations-sponsored Paris Agreement requires member nations to submit non-binding, individually determined emissions reduction goals every five years after 2020. In 2021, the United States rejoined the Paris Agreement and issued its corresponding “nationally determined contribution” (“NDC”) to reduce economy-wide net GHG emissions 50-52% below 2005 levels by 2030. While the NDC does not identify specific actions necessary to achieve these reductions, it lists several sectors as pathways for reductions, including the power, transportation, building, industrial, and agricultural sectors. The administration has acknowledged that a combination of regulatory actions and legislation will be necessary to achieve the U.S. NDC. In regards to legislation, in November 2021 the United States enacted a nearly $1 trillion bipartisan infrastructure law, which provided significant funding for electric vehicles and clean energy technologies. A separate climate spending bill known as the Build Back Better Act, which could impose a fee on methane emissions, among other GHG provisions, remains under consideration in the U.S. Congress. Ultimately, the impacts of these orders, and the terms of any legislation or regulation to implement the United States’ commitment under the Paris Agreement remain unclear at this time.

Additionally, various states and groups of states have adopted or are considering adopting legislation, regulations or other regulatory initiatives that are focused on such areas as GHG cap and trade programs, carbon taxes, reporting and tracking programs, restriction of emissions, electric vehicle mandates and combustion engine phaseouts. Any such legislation or regulatory programs could also increase the cost of consuming, and thereby reduce demand for, the crude oil and refined products that we deliver.

Increasing societal expectations that companies address climate change and use of substitutes for energy commodities may result in increased costs, reduced demand for our customers’ products and our services, reduced profits, increased investigations and litigation, and negative impacts on our unit price and access to capital markets. To the extent that societal pressures or political or other factors are involved, it is possible that such liability could be imposed on us without regard to our causation of or contribution to the asserted damage, or to other mitigating factors.

Furthermore, large institutional lenders have begun to announce their own policies to meet publicly announced climate commitments, which often involve commitments to shift lending activities in the energy sector to meet particular GHG emissions goals. As a result, certain institutional lenders may decide not to provide funding to us based on environmental concerns, which could adversely affect our financial condition and access to capital for potential growth projects. These impacts could be intensified if United States’ financial regulators were to promulgate climate change requirements in the future.

RISKS RELATED TO CYBERSECURITY, DATA SECURITY, AND INFORMATION TECHNOLOGY

We may be subject to information technology system failures, communications network disruptions and data breaches.

We depend on the efficient and uninterrupted operation of hardware and software systems and infrastructure, including our operating, communications and financial reporting systems. These systems are critical in meeting customer expectations, effectively tracking, maintaining and operating our equipment, directing and compensating our employees, and interfacing with our financial reporting system. We have implemented safeguards and other preventative measures to protect our systems and

- 39 -

data, including sophisticated network security and internal control measures; however, our information technology systems and communications network, and those of our information technology and communication service providers, remain vulnerable to interruption by natural disasters, power loss, telecommunications failure, terrorist attacks, vandalism, Internet failures, computer malware, ransomware, cyberattacks, data breaches and other events unforeseen or generally beyond our control. Additionally, the implementation of social distancing measures and other limitations on our employees, service providers and other third parties in response to the COVID-19 pandemic have necessitated in certain cases to switching to remote work arrangements on less secure systems and environments. The increase in companies and individuals working remotely has increased the risk of cyberattacks and potential cybersecurity incidents, both deliberate attacks and unintentional events.

In addition, information technology system failures, network disruptions (whether intentional by a third party or due to natural disaster), breaches of network or data security, or disruption or failure of the network system used to monitor and control pipeline and terminal operations could disrupt our operations by impeding our processing of transactions, our ability to protect customer or company information and our financial reporting. Although we have taken steps to address these concerns by implementing sophisticated network security and internal control measures, a system failure or data security breach could have a material adverse effect on our financial condition, results of operations or cash flows.

Cyberattacks or security breaches could have a material adverse effect on our business, financial condition, results of operations or cash flows.

Our business is dependent upon information technology systems and other digital technologies for controlling our plants and pipelines, processing transactions and summarizing and reporting results of operations. The secure processing, maintenance and transmission of information is critical to our operations. We monitor our information technology systems on a 24/7 basis in an effort to detect cyberattacks, security breaches or unauthorized access. Preventative and detective measures we utilize include independent cybersecurity audits and penetration tests. We implemented these efforts along with other risk mitigation procedures to detect and address unauthorized and damaging activity on our network, stay abreast of the increasing cybersecurity threat landscape and improve our cybersecurity posture. While there have been immaterial incidents of unauthorized access to our information technology systems, we have not experienced any impact on our business or operations from these attacks. In addition, information technology system failures, communications network disruptions (whether intentional by a third party or due to natural disaster), and security breaches could still impact equipment and software used to control plants and pipelines, resulting in improper operation of our assets, potentially including delays in the delivery or availability of our customers’ products, contamination or degradation of the products we transport, store or distribute, or releases of hydrocarbon products and other damage to our facilities for which we could be held liable.

Despite our security measures, our information technology systems may become the target of cyberattacks or security breaches (including employee error, malfeasance or other breaches), which could result in the theft or loss of the stored information, misappropriation of assets, disruption of transactions and reporting functions, our ability to protect confidential information and our financial reporting. Moreover, we may not be able to anticipate, detect or prevent cyberattacks or security breaches, particularly because the methodologies used by attackers change frequently or may not be recognized until such attack is launched, and because attackers are increasingly using technologies specifically designed to circumvent cybersecurity measures and avoid detection. Even with insurance coverage for cyberattacks, data breaches or unauthorized access of our information technology systems, a claim could be denied or coverage delayed. In addition, as technologies evolve, and cyberattacks become increasingly sophisticated, we may incur significant costs to modify, upgrade or enhance our security measures to protect against such cyberattacks and we may face difficulties in fully anticipating or implementing adequate security measures or mitigating potential harm. A cyberattack or security breach could result in liability under data privacy laws, regulatory penalties, damage to our reputation, or additional costs for remediation and modification or enhancement of our information systems to prevent future occurrences, all of which could have a material and adverse effect on our business, financial condition, results of operations or cash flows.

Our business is subject to complex and evolving laws, regulations and security standards regarding privacy, cybersecurity and data protection (“data protection laws”). Many of these data protection laws are subject to change and uncertain interpretation, and could result in claims, changes to our business practices, monetary penalties, increased cost of operations or other harm to our business.

The constantly evolving regulatory and legislative environment surrounding data privacy and protection poses increasingly complex compliance challenges, and complying with such data protection laws could increase the costs and complexity of compliance. While we do not collect significant amounts of personal information from consumers, we do have personal information from our employees, job applicants and some business partners, such as contractors and distributors. Any failure, whether real or perceived, by us to comply with applicable data protection laws could result in proceedings or actions against us by governmental entities or others, subject us to significant fines, penalties, judgments, and negative publicity, require us to change our business practices, increase the costs and complexity of compliance, and adversely affect our business. Our compliance with emerging privacy/security laws, as well as any associated inquiries or investigations or any other government actions related to these laws, may increase our operating costs.

- 40 -

In the second quarter of 2021, the Department of Homeland Security’s Transportation Security Administration (“TSA”) announced two new security directives. These directives require critical pipeline owners to comply with mandatory reporting measures, including, among other things, to appoint personnel, report confirmed and potential cybersecurity incidents to the DHS Cybersecurity and Infrastructure Security Agency (“CISA”) and provide vulnerability assessments. As legislation continues to develop and cyber incidents continue to evolve, we may be required to expend significant additional resources to respond to cyberattacks, to continue to modify or enhance our protective measures, or to detect, assess, investigate and remediate any critical infrastructure security vulnerabilities and report any cyber incidents to the applicable regulatory authorities. Any failure to remain in compliance with these government regulations may results in enforcement actions which may have a material adverse effect on our business and operations.

RISKS RELATED TO LIQUIDITY, FINANCIAL INSTRUMENTS AND CREDIT

We may not be able to retain existing customers or acquire new customers.

The renewal or replacement of existing contracts with our customers at rates sufficient to maintain current revenues and cash flows depends on a number of factors outside our control, including competition from other pipelines and the demand for refined products in the markets that we serve. Our long-term pipeline and terminal, tankage and refinery processing unit throughput agreements with HFC and a third party customer will expire beginning in 2022 through 2036. On September 30, 2019, Delek exercised its first renewal option (the “Renewal”) under this agreement for an additional five-year period beginning April 1, 2020, but only with respect to specific assets. For the refined product pipelines and refined product terminals that were not subject to the Renewal and which accounted for approximately $15 million to $16 million of our annual revenues from Delek as of December 31, 2019, the agreement terminated as of March 31, 2020. We reached a short-term agreement with Delek on a majority of the pipeline and terminal assets that were not part of the Renewal. We continue to explore avenues that will maximize value of the non-Renewal assets.

Our leverage may limit our ability to borrow additional funds, comply with the terms of our indebtedness or capitalize on business opportunities.

As of December 31, 2021, the principal amount of our total outstanding debt was $1,340 million. On February 4, 2020, we closed a private placement of $500 million 5.0% senior notes due 2028 (the “5% Senior Notes”). Various limitations in our Credit Agreement and the indenture for our 5% Senior Notes may reduce our ability to incur additional debt, to engage in some transactions and to capitalize on business opportunities. Any subsequent refinancing of our current indebtedness or any new indebtedness could have similar or greater restrictions.

Our leverage could have important consequences. We require substantial cash flow to meet our payment obligations with respect to our indebtedness. Our ability to make scheduled payments, to refinance our indebtedness or our ability to obtain additional financing in the future will depend on our financial and operating performance, which, in turn, is subject to then-current economic conditions and to financial, business, competitive, regulatory and other factors. We believe that we will have sufficient cash flow from operations and available borrowings under our Credit Agreement to service our indebtedness. However, a significant downturn in our business or other development adversely affecting our cash flow could materially impair our ability to service our indebtedness. We cannot guarantee that we would be able to refinance our existing indebtedness at maturity or otherwise or sell assets on terms that are commercially reasonable.

The instruments governing our debt contain restrictive covenants that may prevent us from engaging in certain transactions. The agreements governing our debt generally require us to comply with various affirmative and negative covenants including the maintenance of certain financial ratios and restrictions on incurring additional debt, entering into mergers, consolidations and sales of assets, making investments and granting liens. Our leverage may adversely affect our ability to fund future working capital, capital expenditures and other general partnership requirements, future acquisitions, construction or development activities, or to otherwise realize fully the value of our assets and opportunities because of the need to dedicate a substantial portion of our cash flow from operations to payments on our indebtedness or to comply with any restrictive terms of our indebtedness. Our leverage also may make our results of operations more susceptible to adverse economic and industry conditions by limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate and may place us at a competitive disadvantage as compared to our competitors that have less debt.

We may not be able to obtain funding on acceptable terms or at all because of volatility and uncertainty in the credit and capital markets. This may hinder or prevent us from meeting our future capital needs.

The domestic and global financial markets and economic conditions are disrupted and volatile from time to time due to a variety of factors, including low consumer confidence, high unemployment, geoeconomic and geopolitical issues, including U.S. government shutdowns, weak economic conditions and uncertainty in the financial services sector. In addition, the fixed-income markets have experienced periods of extreme volatility, which negatively impacted market liquidity conditions. As a

- 41 -

result, the cost of raising money in the debt and equity capital markets has increased substantially at times while the availability of funds from these markets diminished significantly. In particular, as a result of concerns about the stability of financial markets generally and the solvency of lending counterparties specifically, the cost of obtaining money from the credit markets may increase as many lenders and institutional investors increase interest rates, enact tighter lending standards, refuse to refinance existing debt on similar terms or at all and reduce, or in some cases cease, to provide funding to borrowers. In addition, lending counterparties under existing revolving credit facilities and other debt instruments may be unwilling or unable to meet their funding obligations.

Due to these factors, we cannot be certain that new debt or equity financing will be available on acceptable terms. If funding is not available when needed, or is available only on unfavorable terms, we may be unable to:

•continue our business as currently structured and/or conducted;

•meet our obligations as they come due;

•execute our growth strategy;

•complete future acquisitions or construction projects;

•take advantage of other business opportunities; or

•respond to competitive pressures.

Any of the above could have a material adverse effect on our revenues and results of operations.

Increases in interest rates could adversely affect our business.

We use both fixed and variable rate debt, and we are exposed to market risk due to the floating interest rates on our credit facility. In addition, interest rates on future debt offerings could be higher, causing our financing costs to increase accordingly. Our results of operations, cash flows and financial position could be adversely affected by significant increases in interest rates.

The expected phase out of LIBOR could impact the interest rates paid on our variable rate indebtedness and could cause our interest expense to increase.

A portion of our borrowing capacity and outstanding indebtedness bears interest at a variable rate based on the London Interbank Offered Rate (“LIBOR”). The ICE Benchmark Administration Limited (“IBA”) announced that it will cease calculating and publishing all USD LIBOR tenors on June 30, 2023 and cease calculating and publishing certain USD LIBOR tenors on December 31, 2021. Further, U.K. and U.S. regulatory authorities recently issued statements encouraging banks to cease entering into new USD LIBOR based loans by no later than December 31, 2021 and to continue to transition away from USD LIBOR based loans in preparation of IBA ceasing to calculate and publish LIBOR based rates on June 30, 2023. These developments may cause fluctuations in LIBOR rates and pricing of USD LIBOR based loans that are not transitioned to a new benchmark rate.

The agreements that govern our variable rate indebtedness contain customary transition and fallback provisions in contemplation of the cessation of LIBOR. Nevertheless, at this time, it is not possible to predict the effect that these developments, any discontinuance, modification or other reforms to LIBOR or any other reference rate, or the establishment of alternative reference rates may have on LIBOR, other benchmarks or variable rate indebtedness. Uncertainty as to the nature of such potential discontinuance, modification, alternative reference rates or other reforms may materially adversely affect the trading market for securities linked to such benchmarks. Furthermore, the use of alternative reference rates or other reforms could cause the market value of, the applicable interest rate on and the amount of interest paid on our variable rate indebtedness to be materially different than expected and could cause our interest expense to increase.

If we are unable to generate sufficient cash flow, our ability to pay quarterly distributions to our common unitholders at current levels or to increase our quarterly distributions in the future could be impaired materially.

Our ability to pay quarterly distributions depends primarily on cash flow (including cash flow from operations, financial reserves and credit facilities) and not solely on profitability, which is affected by non-cash items. As a result, we may pay cash distributions during periods of losses and may be unable to pay cash distributions during periods of income. Our ability to generate sufficient cash from operations is largely dependent on our ability to manage our business successfully which may also be affected by economic, financial, competitive, regulatory, and other factors that are beyond our control. Because the cash we generate from operations will fluctuate from quarter to quarter, quarterly distributions may also fluctuate from quarter to quarter.

We are exposed to the credit risks and certain other risks, of our or our joint ventures' key customers, vendors, and other counterparties.

We are subject to risks of loss resulting from nonpayment or nonperformance by our or our joint ventures' customers, vendors or other counterparties. We and our joint ventures derive a significant portion of our revenues from contracts with key

- 42 -

customers, particularly HFC, under its pipelines and terminals, tankage, tolling and throughput agreements. To the extent that our or our joint ventures' customers are unable to meet the specifications of their customers, we would be adversely affected unless we were able to make comparably profitable arrangements with other customers.

Mergers among our existing customers could provide strong economic incentives for the combined entities to use systems other than ours, and we could experience difficulty in replacing lost volumes and revenues. Because a significant portion of our operating costs are fixed, a reduction in volumes would result not only in a reduction of revenues, but also a decline in net income and cash flow of a similar magnitude, which would reduce our ability to meet our financial obligations and make distributions to unitholders.

If any of our or our joint ventures' key customers default on their obligations, our financial results could be adversely affected. Furthermore, some of our or our joint ventures' customers may be highly leveraged and subject to their own operating and regulatory risks. In addition, nonperformance by vendors who have committed to provide us with products or services could result in higher costs or interfere with our ability to successfully conduct our business.

Any substantial increase in the nonpayment and/or nonperformance by our or our joint ventures' customers or vendors could have a material adverse effect on our results of operations and cash flows.

In addition, in connection with the acquisition of certain of our assets, we have entered into agreements pursuant to which various counterparties, including HFC, have agreed to indemnify us, subject to certain limitations, for:

•certain pre-closing environmental liabilities discovered within specified time periods after the date of the applicable acquisition;

•certain matters arising from the pre-closing ownership and operation of assets; and

•ongoing remediation related to the assets.

Our business, results of operation, cash flows and our ability to make cash distributions to our unitholders could be adversely affected in the future if third parties fail to satisfy an indemnification obligation owed to us.

Adverse changes in our and/or our general partner's credit ratings and risk profile may negatively affect us.

Our ability to access capital markets is important to our ability to operate our business. Regional and national economic conditions, increased scrutiny of the energy industry and regulatory changes, as well as changes in our economic performance, could result in credit agencies reexamining our credit rating.

We are in compliance with all covenants or other requirements set forth in our Credit Agreement. Further, we do not have any rating downgrade triggers that would automatically accelerate the maturity dates of any debt.

While credit ratings reflect the opinions of the credit agencies issuing such ratings and may not necessarily reflect actual performance, a downgrade in our credit rating could affect adversely our ability to borrow on, renew existing, or obtain access to new financing arrangements, could increase the cost of such financing arrangements, could reduce our level of capital expenditures and could impact our future earnings and cash flows.

The credit and business risk profiles of our general partner, and of HFC as the indirect owner of our general partner, may be factors in credit evaluations of us as a master limited partnership due to the significant influence of our general partner and its indirect ownership over our business activities, including our cash distribution policy, acquisition strategy and business risk profile. Another factor that may be considered is the financial condition of our general partner and its owners, including the degree of their financial leverage and their dependence on cash flow from the partnership to service their indebtedness.

RISKS TO COMMON UNITHOLDERS

HFC and its affiliates may have conflicts of interest and limited fiduciary duties, which may permit them to favor their own interests.

Currently, HFC and certain of its subsidiaries collectively own a 57% limited partner interest and a non-economic general partner interest in us and controls HLS, the general partner of our general partner, HEP Logistics. Conflicts of interest may arise between HFC and its affiliates, including our general partner, on the one hand, and us, on the other hand. As a result of these conflicts, the general partner may favor its own interests and the interests of its other affiliates over our interests. These conflicts include, among others, the following situations:

- 43 -

•HFC, as a shipper on our pipelines, has an economic incentive not to cause us to seek higher tariff rates or terminalling fees, even if such higher rates or terminalling fees would reflect rates that could be obtained in arm's -length, third-party transactions;

•HFC's directors and officers have a fiduciary duty to make business decisions in the best interests of the stockholders of HFC;

•our general partner is allowed to take into account the interests of parties other than us, such as HFC, in resolving conflicts of interest;

•our partnership agreement provides for modified or reduced fiduciary duties for our general partner, and also restricts the remedies available to our unitholders for actions that, without the limitations, might constitute breaches of fiduciary duty;

•our general partner determines which costs incurred by HFC and its affiliates are reimbursable by us;

•our partnership agreement does not restrict our general partner from causing us to pay it or its affiliates for any services rendered to us or entering into additional contractual arrangements with any of these entities on our behalf;

•our general partner may, in some circumstances, cause us to borrow funds to make cash distributions, even where the purpose or effect of the borrowing benefits our general partner or affiliates;

•our general partner determines the amount and timing of our asset purchases and sales, capital expenditures and borrowings, each of which can affect the amount of cash available to us; and

•our general partner controls the enforcement of obligations owed to us by our general partner and its affiliates, including the pipelines and terminals agreement with HFC.

Cost reimbursements, which will be determined by our general partner, and fees due to our general partner and its affiliates for services provided, are substantial.

Under our Omnibus Agreement, we are obligated to pay HFC an administrative fee of currently $2.6 million per year for the provision by HFC or its affiliates of various general and administrative services for our benefit. The administrative fee is subject to an annual upward adjustment for changes in PPI. In addition, we are required to reimburse HFC pursuant to the secondment arrangement for the wages, benefits, and other costs of HFC employees seconded to HLS to perform services at certain of our processing, refining, pipeline and tankage assets. We can neither provide assurance that HFC will continue to provide us the officers and employees that are necessary for the conduct of our business nor that such provision will be on terms that are acceptable to us. If HFC fails to provide us with adequate personnel, our operations could be adversely impacted.

The administrative fee and secondment allocations are subject to annual review and may increase if we make an acquisition that requires an increase in the level of general and administrative services that we receive from HFC or its affiliates. Our general partner will determine the amount of general and administrative expenses that will be allocated to us in accordance with the terms of our partnership agreement. In addition, our general partner and its affiliates are entitled to reimbursement for all other expenses they incur on our behalf, including the salaries of and the cost of employee benefits for employees of HLS who provide services to us.

Prior to making any distribution on the common units, we will reimburse our general partner and its affiliates, including officers and directors of the general partner, for all expenses incurred on our behalf, plus the administrative fee. The reimbursement of expenses and the payment of fees could adversely affect our ability to make distributions. The general partner has sole discretion to determine the amount of these expenses. Our general partner and its affiliates also may provide us other services for which we are charged fees as determined by our general partner.

Increases in interest rates could adversely impact our unit price and our ability to issue additional equity to make acquisitions, fund expansion capital expenditures, or for other purposes.

As with other yield-oriented securities, our unit price is impacted by the level of our cash distributions and implied distribution yield. The distribution yield is often used by investors to compare and rank related yield-oriented securities for investment decision-making purposes. Therefore, changes in interest rates, either positive or negative, may affect the yield requirements of investors who invest in our units and a rising interest rate environment could have an adverse impact on our unit price and our ability to issue additional equity to make acquisitions, fund expansion capital expenditures or for other purposes. If we then issue additional equity at a significantly lower price, material dilution to our existing unitholders could result.

Even if unitholders are dissatisfied, they cannot remove our general partner without its consent.

Unlike the holders of common stock in a corporation, unitholders have only limited voting rights on matters affecting our business and, therefore, limited ability to influence management's decisions regarding our business. Unitholders did not elect our general partner or the board of directors of HLS and have no right to do so on an annual or other continuing basis. The board of directors of HLS is chosen by the sole member of HLS. If unitholders are dissatisfied with the performance of our

- 44 -

general partner, they will have little ability to remove our general partner. As a result of these limitations, the price at which the common units trade could be diminished because of the absence or reduction of a takeover premium in the trading price.

The vote of the holders of at least 66 2/3% of all outstanding units voting together as a single class is required to remove the general partner. Unitholders will be unable to remove the general partner without its consent because the general partner and its affiliates own sufficient units to prevent its removal. Unitholders' voting rights are further restricted by the partnership agreement provision providing that any units held by a person that owns 20% or more of any class of units then outstanding (other than the general partner, its affiliates, their transferees, and persons who acquired such units with the prior approval of the board of directors of the general partner's general partner) cannot vote on any matter; however, no such person currently exists. Our partnership agreement also contains provisions limiting the ability of unitholders to call meetings, acquire information about our operations, and influence the manner or direction of management.

The control of our general partner may be transferred to a third party without unitholder consent.

Our general partner may transfer its general partner interest to a third party in a merger or in a sale of all or substantially all of its assets without the consent of the unitholders. Furthermore, our partnership agreement does not restrict the ability of the partners of our general partner from transferring their respective partnership interests in our general partner to a third party. The new partners of our general partner would then be in a position to replace the board of directors and officers of the general partner of our general partner with their own choices and to control the decisions made by the board of directors and officers.

We may issue additional limited partner units without unitholder approval, which would dilute an existing unitholder's ownership interests.

Under our partnership agreement, provided there is no significant decrease in our operating performance, we may issue an unlimited number of limited partner interests of any type without the approval of our unitholders, and HEP currently has a shelf registration on file with the SEC pursuant to which it may issue up to $2.0 billion in additional common units. On May 10, 2016, HEP established a continuous offering program under the shelf registration statement pursuant to which HEP may issue and sell common units from time to time, representing limited partner interests, up to an aggregate gross sales amount of $200 million. As of December 31, 2021, HEP has issued 2.4 million units under this program for gross consideration of $82.3 million.

The issuance by us of additional common units or other equity securities of equal or senior rank will have the following effects:

•our unitholders' proportionate ownership interest in us will decrease;

•the amount of cash available for distribution on each unit may decrease;

•the relative voting strength of each previously outstanding unit may be diminished; and

•the market price of the common units may decline.

Our partnership agreement does not give our unitholders the right to approve our issuance of equity securities ranking junior to the common units at any time.

In establishing cash reserves, our general partner may reduce the amount of cash available for distribution to unitholders.

Our partnership agreement requires us to distribute all available cash to our unitholders; however, it also requires our general partner to deduct from operating surplus cash reserves that it establishes are necessary to fund our future operating expenditures. In addition, our partnership agreement permits our general partner to reduce available cash by establishing cash reserves for the proper conduct of our business, to comply with applicable law or agreements to which we are a party, or to provide funds for future distributions to partners. These cash reserves will affect the amount of cash available to make the required payments to our debt holders or distributions on our common units every quarter.

HFC and its affiliates may engage in limited competition with us.

HFC and its affiliates may engage in limited competition with us. Pursuant to the Omnibus Agreement, HFC and its affiliates agreed not to engage in the business of operating intermediate or refined product pipelines or terminals, crude oil pipelines or terminals, truck racks or crude oil gathering systems in the continental United States. The Omnibus Agreement, however, does not apply to:

•any business operated by HFC or any of its subsidiaries at the closing of our initial public offering;

•any business or asset that HFC or any of its subsidiaries acquires or constructs that has a fair market value or construction cost of less than $5 million; and

- 45 -

•any business or asset that HFC or any of its subsidiaries acquires or constructs that has a fair market value or construction cost of $5 million or more if we have been offered the opportunity to purchase the business or asset at fair market value, and we decline to do so.

In the event that HFC or its affiliates no longer control our partnership or there is a change of control of HFC, the non-competition provisions of the Omnibus Agreement will terminate.

Our general partner has a limited call right that may require a unitholder to sell its common units at an undesirable time or price.

If at any time our general partner and its affiliates own more than 80% of the common units (which it does not presently), our general partner will have the right (which it may assign to any of its affiliates or to us) but not the obligation to acquire all, but not less than all, of the common units held by unaffiliated persons at a price not less than their then-current market price. As a result, a holder of common units may be required to sell its units at a time or price that is undesirable to it and may not receive any return on its investment. A common unitholder may also incur a tax liability upon a sale of its units.

A unitholder may not have limited liability if a court finds that unitholder actions constitute control of our business or that we have not complied with state partnership law.

Under Delaware law, a unitholder could be held liable for our obligations to the same extent as a general partner if a court determined that the right of unitholders to remove our general partner or to take other action under our partnership agreement constituted participation in the “control” of our business. Our general partner generally has unlimited liability for our obligations, such as our debts and environmental liabilities, except for those contractual obligations that are expressly made without recourse to our general partner.

In addition, Section 17-607 and 17-804 of the Delaware Revised Uniform Limited Partnership Act provides that under some circumstances, a unitholder may be liable to us for the amount of a distribution for a period of three years from the date of the distribution.

Further, we conduct business in a number of states. In some of those states the limitations on the liability of limited partners for the obligations of a limited partnership have not been clearly established. The unitholders might be held liable for the partnership's obligations as if they were a general partner if a court or government agency determined that we were conducting business in the state but had not complied with the state's partnership statute.

HFC may sell units in the public or private markets, and such sales could have an adverse impact on the trading price of the common units. Additionally, HFC may pledge or hypothecate its common units or its interest in us.

HFC currently holds 59,630,030 of our common units, which is approximately 57% of our outstanding common units. The sale of these units in the public or private markets could have an adverse impact on the trading price of our common units. Additionally, we agreed to provide HFC registration rights with respect to our common units that it holds. HFC may pledge or hypothecate its common units, and such pledge or hypothecation may include terms and conditions that might result in an adverse impact on the trading price of our common units.

TAX RISKS TO COMMON UNITHOLDERS

Our tax treatment depends on our status as a partnership for U.S. federal income tax purposes and not being subject to a material amount of entity-level taxation by individual states. If the IRS were to treat us as a corporation for U.S. federal income tax purposes or if we were to become subject to additional amounts of entity-level taxation for federal or state tax purposes, our cash available for distribution to our unitholders could be substantially reduced.

The anticipated after-tax economic benefit of an investment in our common units depends largely on our being treated as a partnership for U.S. federal income tax purposes.

Despite the fact that we are organized as a limited partnership under Delaware law, we would be treated as a corporation for U.S. federal income tax purposes unless we satisfy a “qualifying income” requirement. Based upon our current operations and current Treasury Regulations, we believe we satisfy the qualifying income requirement. Failing to meet the qualifying income requirement or a change in current law could cause us to be treated as a corporation for U.S. federal income tax purposes or otherwise subject us to taxation as an entity.

If we were treated as a corporation for U.S. federal income tax purposes, we would pay U.S. federal income tax on our taxable income at the corporate tax rate. Distributions to unitholders would generally be taxed again as corporate distributions, and no

- 46 -

income, gains, losses or deductions would flow through to unitholders. Because a tax would be imposed upon us as a corporation, our cash available for distribution to unitholders could be substantially reduced. Therefore, our treatment as a corporation could result in a material reduction in the anticipated cash flow and after-tax return to unitholders, likely causing a substantial reduction in the value of our common units.

At the entity level, if we were subject to U.S. federal income tax, we would also be subject to the income tax provisions of many states. Moreover, states are evaluating ways to independently subject partnerships to entity-level taxation through the imposition of state income taxes, franchise taxes and other forms of taxation. For example, we are required to pay Texas margin tax on any income apportioned to Texas, despite our status as a partnership. Imposition of any additional such taxes or an increase in the existing tax rates could reduce the cash available for distributions to our unitholders. Our partnership agreement provides that if a law is enacted or existing law is modified or interpreted in a manner that subjects us to taxation as a corporation or otherwise subjects us to entity-level taxation for federal, state or local income tax purposes, the minimum quarterly distribution amount and the target distribution amounts may be adjusted to reflect the impact of that law on us.

The tax treatment of publicly traded partnerships or an investment in our common units could be subject to potential legislative, judicial or administrative changes or differing interpretations, possibly applied on a retroactive basis.

The present U.S. federal income tax treatment of publicly traded partnerships or an investment in our common units may be modified by administrative, legislative or judicial changes and differing interpretations at any time. Members of Congress have frequently proposed and considered similar substantive changes to the existing U.S. federal income tax laws that would affect publicly traded partnerships, including proposals that would eliminate our ability to qualify for partnership tax treatment.

In addition, the Treasury Department has issued, and in the future may issue, regulations interpreting those laws that affect publicly traded partnerships. There can be no assurance that there will not be further changes to U.S. federal income tax laws or the Treasury Department’s interpretation of the qualifying income rules in a manner that could impact our ability to qualify as a partnership in the future, which could also negatively impact the value of an investment in our common units. Any modification to the U.S. federal income tax laws and interpretations thereof may be applied retroactively and could make it more difficult or impossible for us to meet the qualifying income requirement to be treated as a partnership for U.S. federal income tax purposes. You are urged to consult with your own tax advisor with respect to the status of legislative, regulatory or administrative developments and proposals and their potential effect on your investment in our common units.

If the IRS contests the U.S. federal income tax positions we take, the market for our common units may be adversely impacted, and the cost of any IRS contest will reduce our cash available for distribution to our unitholders.

The IRS may adopt positions that differ from the positions we have taken or may take on tax matters. It may be necessary to resort to administrative or court proceedings to sustain some or all of the positions we take, and a court may not agree with some or all of the positions we take. Any contest with the IRS may materially and adversely impact the market for our common units and the price at which they trade. In addition, the costs of any contest with the IRS would be borne indirectly by our unitholders and general partner because the costs will reduce our cash available for distribution.

If the IRS makes audit adjustments to our income tax returns for tax years beginning after December 31, 2017, it (and some states) may assess and collect any taxes (including any applicable penalties and interest) resulting from such audit adjustment directly from us, in which case our cash available for distribution to our unitholders might be substantially reduced, and our current and former unitholders may be required to indemnify us for any taxes (including any applicable penalties and interest) resulting from such audit adjustments that were paid on their behalf.

Pursuant to the Bipartisan Budget Act of 2015, for tax years beginning after December 31, 2017, if the IRS makes audit adjustments to our income tax returns, it (and some states) may assess and collect any taxes (including any applicable penalties and interest) resulting from such audit adjustment directly from us. Under our partnership agreement, our general partner is permitted to make elections under these rules to either pay the taxes (including any applicable penalties and interest) directly to the IRS or, if we are eligible, issue a revised information statement to each affected current and former unitholder with respect to an audited and adjusted return. Although our general partner may elect to have our affected current and former unitholders take such audit adjustment into account and pay any resulting taxes (including any applicable penalties and interest) in accordance with their interests in us during the tax year under audit, there can be no assurance that such election will be practical, permissible or effective in all circumstances. As a result, our current unitholders may bear some or all of the tax liability resulting from such audit adjustment, even if such unitholders did not own units in us during the tax year under audit. If, as a result of any such audit adjustment, we are required to make payments of taxes, penalties or interest, our cash available for distribution to our unitholders might be substantially reduced, and our current and former unitholders may be required to indemnify us for any taxes (including any applicable penalties and interest) resulting from such audit adjustments that were paid on their behalf. These rules are not applicable for tax years beginning on or prior to December 31, 2017.

- 47 -

Even if unitholders do not receive any cash distributions from us, they will be required to pay taxes on their share of our taxable income.

Unitholders will be required to pay U.S. federal income taxes and, in some cases, state and local income taxes, on their share of our taxable income, whether or not they receive cash distributions from us. For example, if we sell assets and use the proceeds to repay existing debt or fund capital expenditures, unitholders may be allocated taxable income and gain resulting from the sale and our cash available for distribution would not increase. Similarly, taking advantage of opportunities to reduce our existing debt, such as debt exchanges, debt repurchases, or modifications of our existing debt, could result in “cancellation of indebtedness income” being allocated to unitholders as taxable income without any increase in our cash available for distribution. Unitholders may not receive cash distributions from us equal to their share of our taxable income or even equal to the actual tax due from the unitholder with respect to that income.

Tax gain or loss on the disposition of our common units could be more or less than expected.

If a unitholder disposes of common units, it will recognize gain or loss equal to the difference between the amount realized and its tax basis in those common units. Because distributions in excess of a unitholder's allocable share of our net taxable income result in a decrease of the unitholder's tax basis in its common units, the amount, if any, of such prior excess distributions with respect to the units sold will, in effect, become taxable income to the unitholder if it sells such units at a price greater than its tax basis in those units, even if the price the unitholder receives is less than its original cost. In addition, because the amount realized includes a unitholder's share of our nonrecourse liabilities, if unitholders sell their units, they may incur a tax liability in excess of the amount of cash they receive from the sale.

A substantial portion of the amount realized from the sale of a unitholder's common units, whether or not representing gain, may be taxed as ordinary income to the unitholder due to potential recapture items, including depreciation recapture. Thus, the unitholder may recognize both ordinary income and capital loss from the sale of such units if the amount realized on a sale of such units is less than the unitholder's adjusted basis in the units. Net capital loss may only offset capital gains and, in the case of individuals, up to $3,000 of ordinary income per year. In the taxable period in which the unitholder sells its units, the unitholder may recognize ordinary income from our allocations of income and gain to the unitholder prior to the sale and from recapture items that generally cannot be offset by any capital loss recognized upon the sale of units.

Unitholders may be subject to limitation on their ability to deduct interest expense incurred by us.

We are generally entitled to a deduction for interest paid or accrued on indebtedness properly allocable to our trade or business during our taxable year. However, under the Tax Cuts and Jobs Act, for taxable years beginning after December 31, 2017, our deduction for “business interest” is limited to the sum of our business interest income and 30% of our “adjusted taxable income.” For the purposes of this limitation, our adjusted taxable income is computed without regard to any business interest expense or business interest income, and in the case of taxable years beginning before January 1, 2022, any deduction allowable for depreciation, amortization, or depletion to the extent such depreciation, amortization, or depletion is not capitalized into cost of goods sold with respect to inventory.

If our business interest is subject to limitation under these rules, it could result in an increase in the taxable income allocable to a unitholder for such taxable year without any corresponding increase in the cash available for distribution to such unitholder.

Tax-exempt entities face unique tax issues from owning our common units that may result in adverse tax consequences to them.

Investment in our common units by tax-exempt entities, such as employee benefit plans and individual retirement accounts (known as IRAs) raises issues unique to them. For example, virtually all of our income allocated to organizations that are exempt from U.S. federal income tax, including IRAs and other retirement plans, will be unrelated business taxable income and will be taxable to them. Tax-exempt entities should consult a tax advisor before investing in our common units.

Non-U.S. unitholders will be subject to U.S. taxes and withholding with respect to their income and gain from owning our units.

Non-U.S. unitholders are generally taxed and subject to U.S. income tax filing requirements on income effectively connected with a U.S. trade or business (“effectively connected income”). Income allocated to our unitholders and any gain from the sale of our units will generally be considered to be effectively connected with a U.S. trade or business. As a result, distributions to a non-U.S. unitholder will be subject to withholding at the highest applicable effective tax rate, and a non-U.S. unitholder who sells or otherwise disposes of a unit will also be subject to U.S. federal income tax on the gain realized from the sale or disposition of that unit.

- 48 -

Moreover, the transferee of an interest in a partnership that is engaged in a U.S. trade or business is generally required to withhold 10% of the “amount realized” by the transferor unless the transferor certifies that it is not a foreign person. While the determination of a partner’s amount realized generally includes any decrease of a partner’s share of the partnership’s liabilities, the Treasury Regulations provide that the amount realized on a transfer of an interest in a publicly traded partnership, such as our common units, will generally be the amount of gross proceeds paid to the broker effecting the applicable transfer on behalf of the transferor, and thus will be determined without regard to any decrease in that partner’s share of a publicly traded partnership’s liabilities. The Treasury Regulations further provide that withholding on a transfer of an interest in a publicly traded partnership will not be imposed on a transfer that occurs prior to January 1, 2022, and administrative guidance from the IRS further provides that such withholding obligation has been deferred until January 1, 2023. For a transfer of interests in a publicly traded partnership that is effected through a broker on or after January 1, 2023, the obligation to withhold is imposed on the transferor’s broker. Prospective foreign unitholders should consult their tax advisors regarding the impact of these rules on an investment in our common units.

We treat each purchaser of common units as having the same tax benefits without regard to the actual common units purchased. The IRS may challenge this treatment, which could adversely affect the value of the common units.

Because we cannot match transferors and transferees of common units, we have adopted depreciation and amortization positions that may not conform to all aspects of existing Treasury Regulations. A successful IRS challenge to those positions could adversely affect the amount of tax benefits available to our unitholders. It also could affect the timing of these tax benefits or the amount of gain from unitholders' sale of common units and could have a negative impact on the value of our common units or result in audit adjustments.

We generally prorate our items of income, gain, loss and deduction between transferors and transferees of our units each month based upon the ownership of our units on the first day of each month, instead of on the basis of the date a particular unit is transferred. The IRS may challenge this treatment, which could change the allocation of items of income, gain, loss and deduction among our unitholders.

We generally prorate our items of income, gain, loss and deduction between transferors and transferees of our units each month based upon the ownership of our units on the first day of each month (the “Allocation Date”) instead of on the date a particular unit is transferred. Similarly, we generally allocate certain deductions for depreciation of capital additions, gain or loss realized on a sale or other disposition of our assets and, in the discretion of the general partner, any other extraordinary item of income, gain, loss or deduction based upon ownership on the Allocation Date. Treasury Regulations allow a similar monthly simplifying convention, but such regulations do not specifically authorize all aspects of our proration method. If the IRS were to challenge our proration method, we may be required to change the allocation of items of income, gain, loss and deduction among our unitholders.

A unitholder whose units are the subject of a securities loan (e.g., a loan to a “short seller” to cover a short sale of units) may be considered as having disposed of those units. If so, it would no longer be treated for tax purposes as a partner with respect to those units during the period of the loan and may recognize gain or loss from the disposition.

Because there are no specific rules governing the U.S. federal income tax consequences of loaning a partnership interest, a unitholder whose units are the subject of a securities loan may be considered as having disposed of the loaned units. In that case, such unitholder may no longer be treated for tax purposes as a partner with respect to those units during the period of the loan to the short seller and the unitholder may recognize gain or loss from such disposition. Moreover, during the period of the loan, any of our income, gain, loss or deduction with respect to those units may not be reportable by the unitholder and any cash distributions received by the unitholder as to those units could be fully taxable as ordinary income. Unitholders desiring to assure their status as partners and avoid the risk of gain recognition from a securities loan are urged to modify any applicable brokerage account agreements to prohibit their brokers from borrowing their units.

We have adopted certain valuation methodologies in determining a unitholder's allocations of income, gain, loss and deduction. The IRS may challenge these methodologies or the resulting allocations, which could adversely affect the value of our common units.

In determining the items of income, gain, loss and deduction allocable to our unitholders, we must routinely determine the fair market value of our assets. Although we may, from time to time, consult with professional appraisers regarding valuation matters, we make many fair market value estimates using a methodology based on the market value of our common units as a means to measure the fair market value of our assets. The IRS may challenge these valuation methods and the resulting allocations of income, gain, loss and deduction.

A successful IRS challenge to these methods or allocations could adversely affect the amount of taxable income or loss being allocated to our unitholders. It also could affect the amount of gain recognized from our unitholders' sale of common units and

- 49 -

could have a negative impact on the value of the common units or result in audit adjustments to our unitholders' tax returns without the benefit of additional deductions.

Unitholders likely will be subject to state and local taxes and return filing requirements as a result of investing in our common units.

In addition to U.S. federal income tax, unitholders likely will be subject to other taxes, such as state and local income taxes, unincorporated business taxes and estate, inheritance, or intangible taxes that are imposed by the various jurisdictions in which we do business or own property now or in the future. Unitholders likely will be required to file state and local income tax returns and pay state and local income taxes in some or all of these various jurisdictions, even if they do not live in these jurisdictions. Further, unitholders may be subject to penalties for failure to comply with those requirements. We currently own property and conduct business in Texas, New Mexico, Utah, Idaho, Oklahoma, Washington, Kansas, Wyoming and Nevada. We may also own property or conduct business in other states or foreign countries in the future, including following the closing of the HEP Transaction. It is the unitholder's responsibility to file all federal, state, local and foreign tax returns.

Item 1B.Unresolved Staff Comments

We do not have any unresolved SEC staff comments.

Item 3.Legal Proceedings

In the ordinary course of business, we may become party to legal, regulatory or administrative proceedings or governmental investigations, including environmental and other matters. Damages or penalties may be sought from us in some matters and certain matters may require years to resolve. While the outcome and impact of these proceedings and investigations on us cannot be predicted with certainty, based on advice of counsel, management believes that the resolution of these proceedings and investigations, through settlement or adverse judgment, will not, either individually or in the aggregate, have a material adverse effect on our financial condition, results of operations or cash flows.

Item 4.Mine Safety Disclosures

Not applicable.

PART II

Item 5.Market for the Registrant’s Common Units, Related Unitholder Matters and Issuer Purchases of Common Units

Our common limited partner units are traded on the New York Stock Exchange under the symbol “HEP.”

As of February 15, 2022, we had approximately 17,216 common unitholders, including beneficial owners of common units held in street name.

We consider regular cash distributions to unitholders on a quarterly basis, although there is no assurance as to future cash distributions since they are dependent upon future earnings, cash flows, capital requirements, financial condition and other factors. See “Liquidity and Capital Resources” under Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” for a discussion of conditions and limitations prohibiting distributions under the Credit Agreement and indentures relating to our senior notes.

Item 7.Management’s Discussion and Analysis of Financial Condition and Results of Operations

This Item 7, including but not limited to the sections under “Results of Operations” and “Liquidity and Capital Resources,” contains forward-looking statements. See “Forward-Looking Statements” at the beginning of Part I and Item 1A. “Risk Factors.” In this document, the words “we,” “our,” “ours” and “us” refer to Holly Energy Partners, L.P. (“HEP”) and its consolidated subsidiaries or to HEP or an individual subsidiary and not to any other person.

OVERVIEW

HEP is a Delaware limited partnership. Through our subsidiaries and joint ventures we own and/or operate petroleum product and crude oil pipelines, terminal, tankage and loading rack facilities and refinery processing units that support the refining and marketing operations of HollyFrontier Corporation (“HFC”) and other refineries in the Mid-Continent, Southwest and Northwest regions of the United States. HEP, through its subsidiaries and joint ventures, owns and/or operates petroleum product and crude pipelines, tankage and terminals in Texas, New Mexico, Washington, Idaho, Oklahoma, Utah, Nevada, Wyoming and Kansas as well as refinery processing units in Utah and Kansas. HFC owned 57% of our outstanding common units and the non-economic general partner interest as of December 31, 2021.

We generate revenues by charging tariffs for transporting petroleum products and crude oil through our pipelines, by charging fees for terminalling and storing refined products and other hydrocarbons, providing other services at our storage tanks and terminals and charging a tolling fee per barrel or thousand standard cubic feet of feedstock throughput in our refinery processing units. We do not take ownership of products that we transport, terminal or store, and therefore we are not directly exposed to changes in commodity prices.

We believe global refined product demand and US crude production should support high utilization rates for the refineries we serve, which in turn will support volumes in our product pipelines, crude gathering system and terminals.

On August 2, 2021, HEP, The Sinclair Companies (“Sinclair”), and Sinclair Transportation Company, a wholly owned subsidiary of Sinclair (“STC”), entered into a Contribution Agreement (the “Contribution Agreement”) pursuant to which HEP will acquire all of the outstanding shares of STC in exchange for 21 million newly issued common units of HEP and cash consideration equal to $325 million (the “HEP Transaction”), subject to downward adjustment if, as a condition to obtaining antitrust clearance for the Sinclair Transactions (as defined below), HEP agrees to divest a portion of its equity interest in UNEV Pipeline, LLC and the sales price for such interests does not exceed the threshold provided in the Contribution Agreement.

The Sinclair Transactions are expected to close in 2022, subject to customary closing conditions and regulatory clearance, including the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act (the “HSR Act”). On August 23, 2021, each of HFC and Sinclair filed its respective premerger notification and report regarding the Sinclair Transactions with the U.S. Department of Justice and the U.S. Federal Trade Commission (the “FTC”) under the HSR Act. On September 22, 2021, HFC and Sinclair each received a request for additional information and documentary material (“Second Request”) from the FTC in connection with the FTC’s review of the Sinclair Transactions. Issuance of the Second Request extends the waiting period under the HSR Act until 30 days after both HFC and Sinclair have substantially complied with the Second Request, unless the waiting period is terminated earlier by the FTC or the parties otherwise commit not to close the Sinclair Transactions for some additional period of time. HFC and Sinclair are cooperating with the FTC staff in its review and are working diligently to satisfy the closing conditions as soon as possible. In addition, the HEP Transaction is conditioned on the closing of the transactions contemplated by that certain Business Combination Agreement, dated as of August 2, 2021, by and among HFC, Sinclair and certain other parties, which will occur immediately following the HEP Transaction (the “HFC Transaction,” and together with the HEP Transaction, the “Sinclair Transactions”). See Note 2 of Notes to Consolidated Financial Statements included in “Item 1. Financial Statements” for additional information.

Impact of COVID-19 on Our Business

Our business depends in large part on the demand for the various petroleum products we transport, terminal and store in the markets we serve. The initial impact of the COVID-19 pandemic on the global macroeconomy created diminished demand, as well as lack of forward visibility, for refined products and crude oil transportation, and for the terminalling and storage services that we provide. Since the declines in demand at the beginning of the COVID-19 pandemic, we began to see improvement in demand for these products and services beginning late in the second quarter of 2020 that continued through the fourth quarter of 2021, with aggregate volumes approaching pre-pandemic levels. We expect our customers will continue to adjust refinery production levels commensurate with market demand and ultimately expect demand to return to pre-COVID-19 levels.

- 52 -

Most of our employees have returned to work at our locations, and we continue to follow Centers for Disease Control and local government guidance. We will continue to monitor developments in the COVID-19 pandemic and the dynamic environment it has created to properly address these policies going forward.

In 2022, HEP expects to hold its quarterly distribution constant at $0.35 per unit, or $1.40 on an annualized basis. HEP remains committed to its distribution strategy focused on funding all capital expenditures and distributions within operating cash flow and maintaining distributable cash flow coverage of 1.3x or greater with the goal of reducing leverage to 3.0-3.5x.

On March 27, 2020, the United States government passed the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), an approximately $2 trillion stimulus package that included various provisions intended to provide relief to individuals and businesses in the form of tax changes, loans and grants, among others. At this time, we have not sought relief in the form of loans or grants from the CARES Act; however, we have benefited from certain tax deferrals in the CARES Act and may benefit from other tax provisions if we meet the requirements to do so.

The extent to which HEP’s future results are affected by the COVID-19 pandemic will depend on various factors and consequences beyond our control, such as the duration and scope of the pandemic, the effects of any new variant strains of the underlying virus, additional actions by businesses and governments in response to the pandemic and the speed and effectiveness of responses to combat the virus. However, we have long-term customer contracts with minimum volume commitments, which have expiration dates from 2022 to 2036. These minimum volume commitments accounted for approximately 76% of our total revenues in 2021. We are currently not aware of any reasons that would prevent such customers from making the minimum payments required under the contracts or potentially making payments in excess of the minimum payments. In addition to these payments, we also expect to collect payments for services provided to uncommitted shippers. There have been no material changes to customer payment terms due to the COVID-19 pandemic.

The COVID-19 pandemic, and the volatile regional and global economic conditions stemming from it, could also exacerbate the risk factors identified in this Form 10-K under “Risk Factors” in Item 1A. The COVID-19 pandemic may also materially adversely affect our results in a manner that is either not currently known or that we do not currently consider to be a significant risk to our business.

Investment in Joint Venture

On October 2, 2019, HEP Cushing LLC (“HEP Cushing”), a wholly-owned subsidiary of HEP, and Plains Marketing, L.P., a wholly-owned subsidiary of Plains All American Pipeline, L.P. (“Plains”), formed a 50/50 joint venture, Cushing Connect Pipeline & Terminal LLC (the “Cushing Connect Joint Venture”), for (i) the development, construction, ownership and operation of a new 160,000 barrel per day common carrier crude oil pipeline (the “Cushing Connect Pipeline”) that will connect the Cushing, Oklahoma crude oil hub to the Tulsa, Oklahoma refining complex owned by a subsidiary of HFC and (ii) the ownership and operation of 1.5 million barrels of crude oil storage in Cushing, Oklahoma (the “Cushing Connect JV Terminal”). The Cushing Connect JV Terminal went in service during the second quarter of 2020, and the Cushing Connect Pipeline was placed into service at the end of the third quarter of 2021. Long-term commercial agreements have been entered into to support the Cushing Connect Joint Venture assets.

The Cushing Connect Joint Venture has contracted with an affiliate of HEP to manage the construction and operation of the Cushing Connect Pipeline and with an affiliate of Plains to manage the operation of the Cushing Connect JV Terminal. The total Cushing Connect Joint Venture investment will generally be shared equally among the partners. However, we are solely responsible for any Cushing Connect Pipeline construction costs that exceed the budget by more than 10%. HEP estimates its share of the cost of the Cushing Connect JV Terminal contributed by Plains and Cushing Connect Pipeline construction costs are approximately $70 million to $75 million, including $4 million to $6 million of Cushing Connect Pipeline construction costs exceeding the budget by more than 10% to be borne solely by HEP.

Agreements with HFC

We serve HFC's refineries under long-term pipeline, terminal, tankage and refinery processing unit throughput agreements expiring from 2022 to 2036. Under these agreements, HFC agrees to transport, store, and process throughput volumes of refined product, crude oil and feedstocks on our pipelines, terminal, tankage, loading rack facilities and refinery processing units that result in minimum annual payments to us. These minimum annual payments or revenues are subject to annual rate adjustments on July 1st each year based on the PPI or the FERC index. On December 17, 2020, FERC established a new price index for the five-year period commencing July 1, 2021 and ending June 30, 2026, in which common carriers charging indexed rates are permitted to adjust their indexed ceilings annually by Producer Price Index plus 0.78%. FERC received requests for rehearing of its December 17, 2020 order, and on January 20, 2022, FERC revised the index level used to determine annual changes to interstate oil pipeline rate ceilings to Producer Price Index minus 0.21%. The order requires the recalculation of the July 1, 2021

- 53 -

index ceilings to be effective as of March 1, 2022. As of December 31, 2021, these agreements with HFC required minimum annualized payments to us of $352.8 million.

If HFC fails to meet its minimum volume commitments under the agreements in any quarter, it will be required to pay us the amount of any shortfall in cash by the last day of the month following the end of the quarter. Under certain of the agreements, a shortfall payment may be applied as a credit in the following four quarters after minimum obligations are met.

A significant reduction in revenues under the HFC agreements could have a material adverse effect on our results of operations.

On June 1, 2020, HFC announced plans to permanently cease petroleum refining operations at its Cheyenne refinery and to convert certain assets at that refinery to renewable diesel production. HFC subsequently began winding down petroleum refining operations at its Cheyenne refinery on August 3, 2020.

On February 8, 2021, HEP and HFC finalized and executed new agreements for HEP's Cheyenne assets with the following terms, in each case effective January 1, 2021: (1) a ten-year lease with two five-year renewal option periods for HFC’s use of certain HEP tank and rack assets in the Cheyenne refinery to facilitate renewable diesel production with an annual lease payment of approximately $5 million, (2) a five-year contango service fee arrangement that will utilize HEP tank assets inside the Cheyenne refinery where HFC will pay a base tariff to HEP for available crude oil storage and HFC and HEP will split any profits generated on crude oil contango opportunities and (3) a $10 million one-time cash payment from HFC to HEP for the termination of the existing minimum volume commitment.

Under certain provisions of an omnibus agreement that we have with HFC (“Omnibus Agreement”), we pay HFC an annual administrative fee ($2.6 million in 2021), for the provision by HFC or its affiliates of various general and administrative services to us. This fee does not include the salaries of personnel employed by HFC who perform services for us on behalf of HLS or the cost of their employee benefits, which are separately charged to us by HFC. We also reimburse HFC and its affiliates for direct expenses they incur on our behalf.

Under HLS’s Secondment Agreement with HFC, certain employees of HFC are seconded to HLS to provide operational and maintenance services for certain of our processing, refining, pipeline and tankage assets, and HLS reimburses HFC for its prorated portion of the wages, benefits, and other costs of these employees for our benefit.

We have a long-term strategic relationship with HFC that has historically facilitated our growth. Our future growth plans include organic projects around our existing assets and select investments or acquisitions that enhance our service platform while creating accretion for our unitholders. While in the near term, any acquisitions would be subject to economic conditions discussed in “Overview - Impact of COVID-19 on Our Business” above, we also expect over the longer term to continue to work with HFC on logistic asset acquisitions in conjunction with HFC’s refinery acquisition strategies.

Furthermore, we plan to continue to pursue third-party logistic asset acquisitions that are accretive to our unitholders and increase the diversity of our revenues.

A more detailed discussion of our financial condition at December 31, 2021 and 2020 and operating results for the years ended December 31, 2021 and 2020 is presented in the following sections. Discussions of year-over-year comparisons for 2020 and 2019 can be found in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Part II, Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2020.

(1)Earnings before interest, taxes, depreciation and amortization (“EBITDA”) is calculated as net income attributable to the partners plus (i) interest expense, net of interest income, (ii) state income tax and (iii) depreciation and amortization. Adjusted EBITDA is calculated as EBITDA plus (i) loss on early extinguishment of debt, (ii) goodwill impairment, (iii) pipeline tariffs not included in revenues due to impacts from lease accounting for certain pipeline tariffs minus (iv) gain on sales-type leases, (v) gain on significant asset sales, (vi) HEP's pro-rata share of gain on business interruption settlement and (vii) pipeline lease payments not included in operating costs and expenses. Portions of our minimum guaranteed pipeline tariffs for assets subject to sales-type lease accounting are recorded as interest income with the remaining amounts recorded as a reduction in net investment in leases. These pipeline tariffs were previously recorded as revenues prior to the renewal of the throughput agreement, which triggered sales-type lease accounting. Similarly, certain pipeline lease payments were previously recorded as operating costs and expenses, but the underlying lease was reclassified from an operating lease to a financing lease, and these payments are now recorded as interest expense and reductions in the lease liability. EBITDA and Adjusted EBITDA are not calculations based upon generally accepted accounting principles (“GAAP”). However, the amounts included in the EBITDA and Adjusted EBITDA calculations are derived from amounts included in our consolidated financial statements. EBITDA and Adjusted EBITDA should not be considered as alternatives to net income attributable to the partners or operating income, as indications of our operating performance or as alternatives to operating cash flow as a measure of liquidity. EBITDA and Adjusted EBITDA are not necessarily comparable to similarly titled measures of other companies. EBITDA and Adjusted EBITDA are presented here because they are widely used financial indicators used by investors and analysts to measure performance. EBITDA and Adjusted EBITDA are also used by our management for internal analysis and as a basis for compliance with financial covenants.

(2)Distributable cash flow is not a calculation based upon GAAP. However, the amounts included in the calculation are derived from amounts presented in our consolidated financial statements, with the general exception of maintenance capital expenditures. Distributable cash flow should not be considered in isolation or as an alternative to net income or operating income as an indication of our operating performance or as an alternative to operating cash flow as a measure of liquidity. Distributable cash flow is not necessarily comparable to similarly titled measures of other companies. Distributable cash flow is presented here because it is a widely accepted financial indicator used by investors to compare partnership performance. It is also used by management for internal analysis and for our performance units. We believe that this measure provides investors an enhanced perspective of the operating performance of our assets and the cash our business is generating.

Results of Operations — Year Ended December 31, 2021 Compared with Year Ended December 31, 2020

Summary

Net income attributable to the partners for the year ended December 31, 2021, was $214.9 million, a $44.5 million increase compared to the year ended December 31, 2020. Results for the year ended December 31, 2021 reflect special items that collectively increased net income attributable to HEP by a total of $18.9 million. These items include a gain on sales type leases of $24.7 million, a gain on significant asset sales of $5.3 million and a goodwill impairment charge of $11.0 million related to our Cheyenne reporting unit. In addition, net income attributable to HEP for the year ended December 31, 2020 included a goodwill impairment charge of $35.7 million related to our Cheyenne reporting unit, a charge of $25.9 million related to the early redemption of our previously outstanding $500 million aggregate principal amount of 6% Senior Notes due in 2024, a gain on sales-type leases of $33.8 million and a $6.1 million gain related to HEP's pro-rata share of a business interruption insurance claim settlement resulting from a loss at HFC's Woods Cross refinery. Excluding these items, net income attributable to the partners for the year ended December 31, 2021 was $196.0 million ($1.86 per basic and diluted limited partner unit) compared to $192.1 million ($1.82 per basic and diluted limited partner unit) in 2020.

Revenues

Revenues for the year ended December 31, 2021, were $494.5 million, a $3.4 million decrease compared to the same period in 2020. The decrease was mainly attributable to lower on-going revenues from our Cheyenne assets as a result of the conversion of the HFC Cheyenne refinery to renewable diesel production, lower volumes on our product pipelines servicing HFC's Navajo refinery and Delek's Big Spring refinery, and recording certain tariffs and fees as interest income under sales-type lease accounting that were previously recorded as revenue in the year ended December 31, 2020, partially offset by higher revenues from our crude pipeline systems in Wyoming and Utah and our Woods Cross and El Dorado refinery processing units mainly due to higher recovery of natural gas costs.

Revenues from our refined product pipelines were $107.4 million, a decrease of $9.5 million, on shipments averaging 158.1 mbpd compared to 161.5 mbpd for the year ended December 31, 2020. The volume and revenue decreases were mainly due to lower volumes on pipelines servicing HFC's Navajo refinery and Delek's Big Spring refinery.

Revenues from our intermediate pipelines were $30.1 million, an increase of $0.1 million, on shipments averaging 125.2 mbpd compared to 137.1 mbpd for the year ended December 31, 2020. The decrease in volumes was mainly due to lower throughputs on our intermediate pipelines servicing HFC's Tulsa and Navajo refineries while revenue remained relatively constant mainly due to contractual minimum volume guarantees.

Revenues from our crude pipelines were $125.6 million, an increase of $6.7 million, on shipments averaging 408.6 mbpd compared to 387.7 mbpd for the year ended December 31, 2020. The increases were mainly attributable to increased volumes on our crude pipeline systems in Wyoming and Utah partially offset by lower volumes on our pipeline systems servicing HFC's Navajo refinery. Volumes also increased due to the addition of volumes on our Cushing Connect Pipeline in Oklahoma which went into service at the end of the third quarter of 2021.

Revenues from terminal, tankage and loading rack fees were $142.3 million, a decrease of $9.4 million compared to the year ended December 31, 2020. Refined products and crude oil terminalled in the facilities averaged 442.9 mbpd compared to 442.2 mbpd for the year ended December 31, 2020. Revenues decreased mainly due to lower on-going revenues on our Cheyenne assets as a result of the conversion of HFC's Cheyenne refinery to renewable diesel production and recording certain tariffs and fees as interest income under sales-type lease accounting that were previously recorded as revenue in the year ended December 31, 2020.

Revenues from refinery processing units were $89.1 million, an increase of $8.8 million on throughputs averaging 69.6 mbpd compared to 61.4 mbpd for the year ended December 31, 2020. The increase in volumes was mainly due to increased throughput for both our Woods Cross and El Dorado processing units. Revenues increased mainly due to higher recovery of natural gas costs as well as higher throughputs.

Operations Expense

Operations (exclusive of depreciation and amortization) expense for the year ended December 31, 2021, increased by $22.8 million compared to the year ended December 31, 2020. The increase was mainly due to an increase in employee costs, maintenance costs, pipeline rental costs and natural gas costs.

Depreciation and Amortization

Depreciation and amortization for the year ended December 31, 2021, decreased by $5.8 million compared to the year ended December 31, 2020. The decrease was mainly due to the retirements in Cheyenne operations and sale of El Paso 6-inch pipeline assets.

General and Administrative

General and administrative costs for the year ended December 31, 2021, increased by $2.6 million compared to the year ended December 31, 2020 primarily due to costs related to the HEP Transaction.

Total	$	12,432	$	6,647

- 59 -

Equity in earnings of Osage Pipe Line Company, LLC increased for the year ended December 31, 2021, mainly due to higher throughput volumes. Equity in earnings of Cheyenne Pipeline LLC increased for the year ended December 31, 2021, mainly due to the recognition in revenue of prior contractual minimum commitment billings. Equity in earnings of Cushing Connect Terminal Holdings LLC increased for the year ended December 31, 2021 as the terminal started operations in the second quarter of 2020.

Interest Expense

Interest expense for the year ended December 31, 2021, totaled $53.8 million, a decrease of $5.6 million compared to the year ended December 31, 2020. The decrease was mainly due to lower outstanding balances under our senior secured revolving credit facility. Our aggregate weighted-average interest rates were 3.7% and 3.8% for the years ended December 31, 2021 and 2020, respectively.

Interest Income

Interest income for the year ended December 31, 2021, totaled $29.9 million, an increase of $19.3 million compared to the year ended December 31, 2020. The increase was due to recording certain tariffs and fees as interest income under sales-type lease accounting that were previously recorded as revenue in 2020 as underlying agreements were classified as sales-type leases when the agreements were modified or renewed. See Note 5 of our consolidated financial statements for further discussion of lease accounting.

State Income Tax

We recorded state income tax expense of $32,000 and $167,000 for the years ended December 31, 2021 and 2020, respectively. All state income tax expense is solely attributable to the Texas margin tax.

Results of Operations—Year Ended December 31, 2020 Compared with Year Ended December 31, 2019

Summary

Net income attributable to the partners for the year ended December 31, 2020, was $170.5 million, a $54.4 million decrease compared to the year ended December 31, 2019. Results for the year ended December 31, 2020 reflect special items that collectively decreased net income attributable to HEP by a total of $21.7 million. These items include a goodwill impairment charge of $35.7 million related to our Cheyenne reporting unit, a charge of $25.9 million related to the early redemption of our previously outstanding $500 million aggregate principal amount of 6% Senior Notes due in 2024, a gain on sales type leases of $33.8 million and a $6.1 million gain related to HEP's pro-rata share of a business interruption insurance claim settlement resulting from a loss at HFC's Woods Cross refinery. In addition, net income attributable to HEP for the year ended December 31, 2019 included a gain on sales-type leases of $35.2 million. Excluding these items, net income attributable to the partners for the year ended December 31, 2020 was $192.1 million ($1.82 per basic and diluted limited partner unit) compared to $189.7 million ($1.80 per basic and diluted limited partner unit) in 2019.

Revenues

Revenues for the year ended December 31, 2020, were $497.8 million, a $34.9 million decrease compared to the same period of 2019. The decrease was mainly attributable to an 18% reduction in overall crude and product pipeline volumes predominantly in our Southwest and Northwest regions.

Revenues from our refined product pipelines were $116.9 million, a decrease of $15.4 million, on shipments averaging 161.5 mbpd compared to 195.5 mbpd for the year ended December 31, 2019. The volume and revenue decreases were mainly due to lower volumes on pipelines servicing HFC's Navajo refinery, Delek's Big Spring refinery and our UNEV pipeline largely as a result of demand destruction associated with the COVID-19 pandemic as well as the recording of certain pipeline tariffs as interest income as the related throughput contract renewals were determined to be sales-type leases.

Revenues from our intermediate pipelines were $30.0 million, an increase of $0.5 million, on shipments averaging 137.1 mbpd compared to 140.6 mbpd for the year ended December 31, 2019.

Revenues from our crude pipelines were $118.9 million, a decrease of $11.8 million, on shipments averaging 387.7 mbpd compared to 501.2 mbpd for the year ended December 31, 2019. The decreases were mainly attributable to decreased volumes on our crude pipeline systems in the Permian Basin, Wyoming and Utah largely as a result of demand destruction associated with the COVID-19 pandemic.

Revenues from terminal, tankage and loading rack fees were $151.7 million, a decrease of $8.8 million compared to the year ended December 31, 2019. Refined products and crude oil terminalled in the facilities averaged 442.2 mbpd compared to 483.2

- 60 -

mbpd for the year ended December 31, 2019. The revenue and volume decreases were mainly as a result of demand destruction associated with the COVID-19 pandemic across many of our facilities.

Revenues from refinery processing units were $80.3 million, an increase of $0.6 million on throughputs averaging 61.4 mbpd compared to 68.8 mbpd for 2019. The decrease in volumes was mainly due to reduced throughput for both our Woods Cross and El Dorado processing units largely as a result of demand destruction associated with the COVID-19 pandemic. Revenues remained relatively constant due to contractual minimum volume guarantees.

Operations Expense

Operations (exclusive of depreciation and amortization) expense for the year ended December 31, 2020, decreased by $14.3 million compared to the year ended December 31, 2019. The decrease was mainly due to lower rental expenses, property taxes and variable costs such as electricity and chemicals associated with lower volumes.

Depreciation and Amortization

Depreciation and amortization for the year ended December 31, 2020, increased by $2.9 million compared to the year ended December 31, 2019. The increase was mainly due to the acceleration of depreciation on certain of our Cheyenne tanks.

General and Administrative

General and administrative costs for the year ended December 31, 2020, decreased by $0.3 million compared to the year ended December 31, 2019, mainly due to lower legal expenses.

Interest Expense

Interest expense for the year ended December 31, 2020, totaled $59.4 million, a decrease of $17.4 million compared to the year ended December 31, 2019. The decrease was mainly due to market interest rate decreases under our senior secured revolving credit facility and refinancing our $500 million aggregate principal amount of 6% senior notes due 2024 to $500 million aggregate principal amount of 5% Senior Notes due 2028. Our aggregate weighted-average interest rates were 3.8% and 5.4% for the years ended December 31, 2020 and 2019, respectively.

State Income Tax

We recorded state income tax expense of $167,000 and 41,000 for the years ended December 31, 2020 and 2019, respectively. All state income tax expense is solely attributable to the Texas margin tax.

LIQUIDITY AND CAPITAL RESOURCES

Overview

We have a $1.2 billion senior secured revolving credit facility (the “Credit Agreement”) expiring in July 2025. The Credit Agreement is available to fund capital expenditures, investments, acquisitions, distribution payments and working capital and for general partnership purposes. The Credit Agreement is also available to fund letters of credit up to a $50 million sub-limit and continues to provide for an accordion feature that allows us to increase commitments under the Credit Agreement up to a maximum amount of $1.7 billion.

During the year ended December 31, 2021, we received advances totaling $480.5 million and repaid $554.0 million, resulting in a net decrease of $73.5 million under the Credit Agreement and an outstanding balance of $840.0 million at December 31, 2021. As of December 31, 2021, we had no letters of credit outstanding under the Credit Agreement, and the available capacity under the Credit Agreement was $360.0 million.

- 61 -

On February 4, 2020, we closed a private placement of $500 million in aggregate principal amount of 5% senior unsecured notes due in 2028 (the “5% Senior Notes”). On February 5, 2020, we redeemed the existing $500 million 6% Senior Notes at a redemption cost of $522.5 million, at which time we recognized a $25.9 million early extinguishment loss consisting of a $22.5 million debt redemption premium and unamortized financing costs of $3.4 million. We funded the $522.5 million redemption with proceeds from the issuance of our 5% Senior Notes and borrowings under our Credit Agreement.

We have a continuous offering program under which we may issue and sell common units from time to time, representing limited partner interests, up to an aggregate gross sales amount of $200 million. As of December 31, 2021, HEP had issued 2,413,153 units under this program, providing $82.3 million in gross proceeds.

Under our registration statement filed with the Securities and Exchange Commission (“SEC”) using a “shelf” registration process, we currently have the authority to raise up to $2.0 billion by offering securities, through one or more prospectus supplements that would describe, among other things, the specific amounts, prices and terms of any securities offered and how the proceeds would be used. Any proceeds from the sale of securities are expected to be used for general business purposes, which may include, among other things, funding acquisitions of assets or businesses, working capital, capital expenditures, investments in subsidiaries, the retirement of existing debt and/or the repurchase of common units or other securities.

We believe our current sources of liquidity, including cash balances, future internally generated funds, and funds available under the Credit Agreement, as well as our access to additional bank financing, and public or private capital markets, will provide sufficient resources to meet our working capital liquidity, capital expenditure and quarterly distribution needs for the foreseeable future, including funding the cash portion of the HEP Transaction. Future securities issuances, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors.

In February, May, August and November 2021, we paid regular quarterly cash distributions of $0.3500, $0.3500, $0.3500 and $0.3500, respectively, on all units in an aggregate amount of $149.4 million. In February 2022, we paid a regular quarterly cash distribution of $0.3500 on all units in an aggregate amount of $37.0 million.

Cash and cash equivalents decreased by $7.6 million during the year ended December 31, 2021. The cash flows provided by operating activities of $294.1 million were less than the cash flows used for investing and financing activities of $78.5 million and $223.2 million, respectively. Working capital increased by $3.2 million to a surplus of $17.5 million at December 31, 2021 from a surplus of $14.2 million at December 31, 2020.

Additionally, we paid $273.2 million in regular quarterly cash distributions to HEP unitholders and $9.0 million to our noncontrolling interests.

Capital Requirements

Our pipeline and terminalling operations are capital intensive, requiring investments to maintain, expand, upgrade or enhance existing operations and to meet environmental and operational regulations. Our capital requirements have consisted of, and are expected to continue to consist of, maintenance capital expenditures and expansion capital expenditures. “Maintenance capital expenditures” represent capital expenditures to replace partially or fully depreciated assets to maintain the operating capacity of existing assets. Maintenance capital expenditures include expenditures required to maintain equipment reliability, tankage and pipeline integrity, safety and to address environmental regulations. “Expansion capital expenditures” represent capital expenditures to expand the operating capacity of existing or new assets, but exclude acquisitions. Expansion capital expenditures include expenditures to grow our business and to expand existing facilities, such as projects that increase throughput capacity on our pipelines and in our terminals. Repair and maintenance expenses associated with existing assets that are minor in nature and do not extend the useful life of existing assets are charged to operating expenses as incurred.

Each year the board of directors of HLS, our ultimate general partner, approves our annual capital budget, which specifies capital projects that our management is authorized to undertake. Additionally, at times when conditions warrant or as new opportunities arise, additional projects may be approved. The funds allocated for a particular capital project may be expended over a period in excess of a year, depending on the time required to complete the project. Therefore, our planned capital expenditures for a given year consist of expenditures approved for capital projects included in the current year’s capital budget as well as, in certain cases, expenditures approved for capital projects in capital budgets for prior years. Our current 2022 capital forecast is comprised of approximately $15 million to $20 million for maintenance capital expenditures, $35 million to $50 million for refinery unit turnarounds and $5 to $10 million for expansion capital expenditures, excluding any expenditures related to the HEP Transaction. In addition to our capital budget, we may spend funds periodically to perform capital upgrades or additions to our assets where a customer reimburses us for such costs. The upgrades or additions would generally benefit the customer over the remaining life of the related service agreements.

We expect that our currently planned sustaining and maintenance capital expenditures, as well as expenditures for capital development projects, will be funded with cash generated by operations. We expect that, to the extent necessary, we can raise additional funds from time to time through equity or debt financings in the public and private capital markets.

Under the terms of the transaction to acquire HFC’s 75% interest in UNEV, we issued to HFC a Class B unit comprising a noncontrolling equity interest in a wholly-owned subsidiary subject to redemption to the extent that HFC is entitled to a 50% interest in our share of annual UNEV earnings before interest, income taxes, depreciation, and amortization above $30 million beginning July 1, 2015, and ending in June 2032, subject to certain limitations. However, to the extent earnings thresholds are not achieved, no redemption payments are required. No redemption payments have been required to date.

Credit Agreement

We have a $1.2 billion senior secured revolving credit facility (the “Credit Agreement”) expiring in July 2025. The Credit Agreement is available to fund capital expenditures, investments, acquisitions, distribution payments and working capital and for general partnership purposes. The Credit Agreement is also available to fund letters of credit up to a $50 million sub-limit and continues to provide for an accordion feature that allows us to increase commitments under the Credit Agreement up to a maximum amount of $1.7 billion. As of December 31, 2021, we had outstanding borrowings of $840.0 million under the Credit Agreement, no letters of credit outstanding, and the available capacity was $360.0 million.

Our obligations under the Credit Agreement are collateralized by substantially all of our assets, and indebtedness under the Credit Agreement is guaranteed by our material wholly-owned subsidiaries. The Credit Agreement requires us to maintain compliance with certain financial covenants consisting of total leverage, senior secured leverage and interest coverage. It also limits or restricts our ability to engage in certain activities. If, at any time prior to the expiration of the Credit Agreement, HEP obtains two investment grade credit ratings, the Credit Agreement will become unsecured and many of the covenants, limitations, and restrictions will be eliminated.

We may prepay all loans at any time without penalty, except for tranche breakage costs. If an event of default exists under the Credit Agreement, the lenders will be able to accelerate the maturity of all loans outstanding and exercise other rights and remedies. We were in compliance with all covenants as of December 31, 2021.

Indebtedness under the Credit Agreement bears interest, at our option, at either (a) the reference rate as announced by the administrative agent plus an applicable margin (ranging from 0.50% to 1.50%) or (b) at a rate equal to LIBOR plus an applicable margin (ranging from 1.50% to 2.50%). In each case, the applicable margin is based upon the ratio of our funded debt (as defined in the Credit Agreement) to EBITDA (earnings before interest, taxes, depreciation and amortization, as defined in the Credit Agreement). The weighted-average interest rates on our Credit Agreement borrowings for the years ending December 31, 2021 and 2020, were 2.30% and 2.58%, respectively. We incur a commitment fee on the unused portion of the Credit Agreement at an annual rate ranging from 0.25% to 0.50% based upon the ratio of our funded debt to EBITDA for the four most recently completed fiscal quarters.

Senior Notes

As of December 31, 2021, we had $500 million in aggregate principal amount of 5% Senior Notes due in 2028.

On February 4, 2020, we closed the private placement of $500 million in aggregate principal amount of 5% senior unsecured notes due in 2028 (the “5% Senior Notes”). On February 5, 2020, we redeemed the existing $500 million 6% Senior Notes at a redemption cost of $522.5 million, at which time we recognized a $25.9 million early extinguishment loss consisting of a $22.5 million debt redemption premium and unamortized financing costs of $3.4 million. We funded the $522.5 million redemption with proceeds from the issuance of our 5% Senior Notes and borrowings under our Credit Agreement.

The 5% Senior Notes are unsecured and impose certain restrictive covenants, including limitations on our ability to incur additional indebtedness, make investments, sell assets, incur certain liens, pay distributions, enter into transactions with affiliates, and enter into mergers. We were in compliance with the restrictive covenants for the 5% Senior Notes as of December 31, 2021. At any time when the 5% Senior Notes are rated investment grade by either Moody’s or Standard & Poor’s and no default or event of default exists, we will not be subject to many of the foregoing covenants. Additionally, we have certain redemption rights at varying premiums over face value under the 5% Senior Notes.

Indebtedness under the 5% Senior Notes is guaranteed by all of our existing wholly-owned subsidiaries (other than Holly Energy Finance Corp. and certain immaterial subsidiaries).

Long-term debt consists of outstanding principal under the Credit Agreement and the 5% Senior Notes. Interest on the Credit Agreement is calculated using the rate in effect at December 31, 2021.

Site service fees consist of site service agreements with HFC, expiring in 2058 through 2066, for the provision of certain facility services and utility costs that relate to our assets located at HFC’s refinery facilities. We are presenting obligations for the full term of these agreements; however, the agreements can be terminated with 180 day notice if we cease to operate the applicable assets.

The pipeline finance lease amounts above reflect the exercise of the second 10-year extension, expiring in 2027, on our lease agreement for the refined products pipeline between White Lakes Junction and Kuntz Station in New Mexico.

Most of our right-of-way agreements are renewable on an annual basis, and the right-of-way agreements payments above include only obligations under the remaining non-cancelable terms of these agreements at December 31, 2021. For the foreseeable future, we intend to continue renewing these agreements and expect to incur right-of-way expenses in addition to the payments listed.

Other contractual obligations include capital lease obligations related to vehicles leases, office space leases, and other.

Impact of Inflation

After being relatively moderate in recent years, inflation in the United States increased significantly during 2021. However, inflation did not have a material impact on our results of operations for the years ended December 31, 2021, 2020 and 2019. PPI has increased an average of 2.9% annually over the past five calendar years, including an increase of 8.9% in 2021 and a decrease of 1.3% in 2020.

The substantial majority of our revenues are generated under long-term contracts that provide for increases or decreases in our rates and minimum revenue guarantees annually for increases or decreases in the PPI. Most of these annual PPI percentage rate increases or decreases go into effect on July 1st of the following year. Certain of these contracts have provisions that limit the level of annual PPI percentage rate increases or decreases. A significant and prolonged period of high inflation or a significant and prolonged period of negative inflation could adversely affect our cash flows and results of operations if costs increase at a rate greater than the fees we charge our shippers.

Environmental Matters

Our operation of pipelines, terminals, and associated facilities in connection with the transportation and storage of refined products and crude oil is subject to stringent and complex federal, state, and local laws and regulations governing the discharge of materials into the environment, or otherwise relating to the protection of the environment. As with the industry generally, compliance with existing and anticipated laws and regulations increases our overall cost of business, including our capital costs to construct, maintain, and upgrade equipment and facilities. While these laws and regulations affect our maintenance capital expenditures and net income, we believe that they do not affect our competitive position given that the operations of our competitors are similarly affected. However, these laws and regulations, and the interpretation or enforcement thereof, are subject to frequent change by regulatory authorities, and we are unable to predict the ongoing cost to us of complying with these laws and regulations or the future impact of these laws and regulations on our operations. Violation of environmental laws, regulations, and permits can result in the imposition of significant administrative, civil and criminal penalties, injunctions, and construction bans or delays. A major discharge of hydrocarbons or hazardous substances into the environment could, to the extent the event is not insured, subject us to substantial expense, including both the cost to comply with applicable laws and regulations and claims made by employees, neighboring landowners and other third parties for personal injury and property damage.

Contamination resulting from spills of refined products and crude oil is not unusual within the petroleum pipeline industry. Historic spills along our existing pipelines and terminals as a result of past operations have resulted in contamination of the environment, including soils and groundwater. Site conditions, including soils and groundwater, are being evaluated at a few of our properties where operations may have resulted in releases of hydrocarbons and other wastes, none of which we believe will have a significant effect on our operations since the remediation of such releases would be covered under environmental indemnification agreements.

Under the Omnibus Agreement and certain transportation agreements and purchase agreements with HFC, HFC has agreed to indemnify us, subject to certain monetary and time limitations, for environmental noncompliance and remediation liabilities associated with certain assets transferred to us from HFC and occurring or existing prior to the date of such transfers.

We have an environmental agreement with Delek with respect to pre-closing environmental costs and liabilities relating to the pipelines and terminals acquired from Delek in 2005, under which Delek will indemnify us subject to certain monetary and time limitations.

There are environmental remediation projects in progress that relate to certain assets acquired from HFC. Certain of these projects were underway prior to our purchase and represent liabilities retained by HFC. As of December 31, 2021, we have an accrual of $3.9 million that relates to environmental clean-up projects for which we have assumed liability or for which the indemnity provided for by HFC has expired. The remaining projects, including assessment and monitoring activities, are covered under the HFC environmental indemnification discussed above and represent liabilities of HFC.

CRITICAL ACCOUNTING ESTIMATES

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities as of the date of the financial statements. Actual results may differ from these estimates under different assumptions or conditions. We consider the following policies to be the most critical to understanding the judgments that are involved and the uncertainties that could impact our results of operations, financial condition and cash flows.

Revenue Recognition

Revenues are generally recognized as products are shipped through our pipelines and terminals, feedstocks are processed through our refinery processing units or other services are rendered. The majority of our contracts with customers meet the definition of a lease since (1) performance of the contracts is dependent on specified property, plant, or equipment and (2) the possibility is remote that one or more parties other than the customer will take more than a minor amount of the output associated with the specified property, plant, or equipment. Prior to the adoption of the new lease standard (see below), we bifurcated the consideration received between lease and service revenue. The new lease standard allows the election of a practical expedient whereby a lessor does not have to separate non-lease (service) components from lease components under certain conditions. The majority of our contracts meet these conditions, and we have made this election for those contracts. Under this practical expedient, we treat the combined components as a single performance obligation in accordance with Accounting Standards Codification (“ASC”) 606, which largely codified ASU 2014-09, if the non-lease (service) component is

- 66 -

the dominant component. If the lease component is the dominant component, we treat the combined components as a lease in accordance with ASC 842, which largely codified ASU 2016-02.

Several of our contracts include incentive or reduced tariffs once a certain quarterly volume is met. Revenue from the variable element of these transactions is recognized based on the actual volumes shipped as it relates specifically to rendering the services during the applicable quarter.

The majority of our long-term transportation contracts specify minimum volume requirements, whereby, we bill a customer for a minimum level of shipments in the event a customer ships below their contractual requirements. If there are no future performance obligations, we will recognize these deficiency payments in revenue.

In certain of these throughput agreements, a customer may later utilize such shortfall billings as credit towards future volume shipments in excess of its minimum levels within its respective contractual shortfall make-up period. Such amounts represent an obligation to perform future services, which may be initially deferred and later recognized as revenue based on estimated future shipping levels, including the likelihood of a customer’s ability to utilize such amounts prior to the end of the contractual shortfall make-up period. We recognize these deficiency payments in revenue when we do not expect we will be required to satisfy these performance obligations in the future based on the pattern of rights projected to be exercised by the customer.

Leases

We adopted ASC 842 effective January 1, 2019, and elected to adopt using the modified retrospective transition method and practical expedients, both of which are provided as options by the standard and further defined below.

Lessee Accounting - At inception, we determine if an arrangement is or contains a lease. Right-of-use assets represent our right to use an underlying asset for the lease term, and lease liabilities represent our payment obligation under the leasing arrangement. Right-of-use assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. We use our estimated incremental borrowing rate (“IBR”) to determine the present value of lease payments as most of our leases do not contain an implicit rate. Our IBR represents the interest rate which we would pay to borrow, on a collateralized basis, an amount equal to the lease payments over a similar term in a similar economic environment. We use the implicit rate when readily determinable.

Operating leases are recorded in operating lease right-of-use assets and current and noncurrent operating lease liabilities on our consolidated balance sheet. Finance leases are included in properties and equipment, current finance lease liabilities and noncurrent finance lease liabilities on our consolidated balance sheet.

When renewal options are defined in a lease, our lease term includes an option to extend the lease when it is reasonably certain we will exercise that option. Leases with a term of 12 months or less are not recorded on our balance sheet, and lease expense is accounted for on a straight-line basis. In addition, as a lessee, we separate non-lease components that are identifiable and exclude them from the determination of net present value of lease payment obligations.

Lessor Accounting - Customer contracts that contain leases are generally classified as either operating leases, direct finance leases or sales-type leases. We consider inputs such as the lease term, fair value of the underlying asset and residual value of the underlying assets when assessing the classification.

Goodwill and Long-Lived Assets

Goodwill represents the excess of our cost of an acquired business over the fair value of the assets acquired, less liabilities assumed. Goodwill is not amortized. We test goodwill at the reporting unit level for impairment annually and between annual tests if events or changes in circumstances indicate the carrying amount may exceed fair value. Our goodwill impairment testing first entails a comparison of our reporting unit fair values relative to their respective carrying values, including goodwill. If carrying value exceeds the estimated fair value for a reporting unit, we measure goodwill impairment as the excess of the carrying amount of the reporting unit over the estimated fair value of the reporting unit.

The changes due to our new agreements with HFC related to our Cheyenne assets resulted in an increase in the net book value of our Cheyenne reporting unit during the first quarter of 2021 due to sales-type lease accounting, which led us to determine indicators of potential goodwill impairment for our Cheyenne reporting unit were present. Therefore, we performed an interim quantitative review of our Cheyenne reporting unit goodwill for the first quarter of 2021.

- 67 -

The estimated fair value of our Cheyenne reporting unit was derived using a combination of income and market approaches. The income approach reflects expected future cash flows based on anticipated gross margins, operating costs and capital expenditures. The market approaches include both the guideline public company and guideline transaction methods. Both methods utilize pricing multiples derived from historical market transactions of other like-kind assets. These fair value measurements involve significant unobservable inputs (Level 3 inputs). See Note 6 for further discussion of Level 3 inputs.

Our interim impairment testing of our Cheyenne reporting unit goodwill identified an impairment charge of $11.0 million, which was recorded in the three months ended March 31, 2021.

Our annual goodwill impairment testing was performed on a qualitative basis during the third quarter of 2021. We assessed qualitative factors such as macroeconomic conditions, cost factors, and reporting unit financial performance and determined it was not more likely than not that fair value of our reporting units was less than the respective carrying value. Therefore, in accordance with GAAP, further testing was not required.

In 2020, our annual goodwill testing was performed on a quantitative basis with the estimated fair value of our reporting units derived using a combination of both income and market approaches as described above. Our annual testing of goodwill did not identify any impairments other than our Cheyenne reporting unit, which reported goodwill impairment charges of $35.7 million for the year ending December 31, 2020.

We evaluate long-lived assets, including finite-lived intangible assets, for potential impairment by identifying whether indicators of impairment exist and, if so, assessing whether the long-lived assets are recoverable from estimated future undiscounted cash flows. The actual amount of impairment loss, if any, to be recorded is equal to the amount by which a long-lived asset’s carrying value exceeds its fair value.

RISK MANAGEMENT

The market risk inherent in our debt positions is the potential change arising from increases or decreases in interest rates as discussed below.

At December 31, 2021, we had an outstanding principal balance of $500 million on our 5% Senior Notes. A change in interest rates generally would affect the fair value of the 5% Senior Notes, but not our earnings or cash flows. At December 31, 2021, the fair value of our 5% Senior Notes was $502.7 million. We estimate a hypothetical 10% change in the yield-to-maturity applicable to the 5% Senior Notes at December 31, 2021, would result in a change of approximately $12.9 million in the fair value of the underlying 5% Senior Notes.

For the variable rate Credit Agreement, changes in interest rates would affect cash flows, but not the fair value. At December 31, 2021, borrowings outstanding under the Credit Agreement were $840.0 million. A hypothetical 10% change in interest rates applicable to the Credit Agreement would not materially affect our cash flows.

Borrowings under our variable rate Credit Agreement bear interest at a variable rate based on the London Interbank Offered Rate (“LIBOR”). The ICE Benchmark Administration Limited (“IBA”) announced that it will cease calculating and publishing all USD LIBOR tenors on June 30, 2023, and ceased calculating and publishing certain USD LIBOR tenors on December 31, 2021. Further, U.K. and U.S. regulatory authorities issued statements encouraging banks to cease entering into new USD LIBOR based loans by no later than December 31, 2021 and to continue to transition away from USD LIBOR based loans in preparation of IBA ceasing to calculate and publish LIBOR based rates on June 30, 2023. These developments may cause fluctuations in LIBOR rates and pricing of USD LIBOR based loans that are not transitioned to an alternative reference rate. While we do not expect the transition to an alternative reference rate to have a significant impact on our business or operations, it is possible that the use of alternative reference rates or other reforms could cause the market value of, the applicable interest rate on and the amount of interest paid on our variable rate indebtedness to be materially different than expected and could cause our interest expense to increase.

Our operations are subject to normal hazards of operations, including fire, explosion and weather-related perils. We maintain various insurance coverages, including business interruption insurance, subject to certain deductibles. We are not fully insured against certain risks because such risks are not fully insurable, coverage is unavailable, or premium costs, in our judgment, do not justify such expenditures.

- 68 -

We have a risk management oversight committee that is made up of members from our senior management. This committee monitors our risk environment and provides direction for activities to mitigate, to an acceptable level, identified risks that may adversely affect the achievement of our goals.

Item 7A.Quantitative and Qualitative Disclosures about Market Risk

Market risk is the risk of loss arising from adverse changes in market rates and prices. See “Risk Management” under “Management’s Discussion and Analysis of Financial Condition and Results of Operations” for a discussion of market risk exposures that we have with respect to our long-term debt. We utilize derivative instruments to hedge our interest rate exposure, as discussed under “Risk Management.”

Since we do not own products shipped on our pipelines or terminalled at our terminal facilities, we do not have direct market risks associated with commodity prices.

Item 8.Financial Statements and Supplementary Data

MANAGEMENT’S REPORT ON ITS ASSESSMENT OF THE PARTNERSHIP’S INTERNAL CONTROL OVER FINANCIAL REPORTING

Management of Holly Energy Partners, L.P. (the “Partnership”) is responsible for establishing and maintaining adequate internal control over financial reporting.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

Management assessed the Partnership’s internal control over financial reporting as of December 31, 2021, using the criteria for effective control over financial reporting established in “Internal Control – Integrated Framework” issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on this assessment, management concluded that, as of December 31, 2021, the Partnership maintained effective internal control over financial reporting.

The Partnership’s independent registered public accounting firm has issued an attestation report on the effectiveness of the Partnership’s internal control over financial reporting as of December 31, 2021. That report appears on page 70.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Unitholders of Holly Energy Partners, L.P. and the Board of Directors of Holly Logistic Services, L.L.C.

Opinion on Internal Control Over Financial Reporting

We have audited Holly Energy Partners, L.P.’s internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Holly Energy Partners, L.P. (the Partnership) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Partnership as of December 31, 2021 and 2020, the related consolidated statements of income, cash flows, and equity for each of the three years in the period ended December 31, 2021, and the related notes and our report dated February 23, 2022 expressed an unqualified opinion thereon.

Basis for Opinion

The Partnership’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on its Assessment of the Partnership’s Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Partnership’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

	Revenue Recognition
Description of the Matter	For the year ended December 31, 2021, the Partnership’s total revenues were $494.5 million. As discussed in Note 1 and Note 4 of the financial statements, revenues are generally recognized as products are shipped through pipelines and terminals, feedstocks are processed through the refinery processing units or other services are rendered. The majority of the Partnership’s long-term throughput agreements with customers specify minimum volume requirements. In the event a customer does not fulfill minimum volume requirements during a contractual period, the Partnership can bill the customer for the minimum level. In certain contracts, a customer may later utilize these shortfall billings as credit towards future throughput volumes in excess of minimum levels within a respective contractual shortfall make-up period. Shortfall billing amounts represent an obligation to provide future shipping services and may be initially deferred and later recognized as revenue. Recognition is based on estimated future throughput volumes, including the likelihood of a customer’s ability to utilize such amounts prior to the end of the contractual shortfall make-up period or when the Partnership does not expect to be required to satisfy these performance obligations in the future based on the pattern of rights exercised by the customer. Auditing the measurement of the Partnership’s revenue was complex and judgmental due to various contractual provisions used in customer agreements and measurement uncertainty associated with management’s estimates of deferred revenue related to the future utilization of shortfall billings.
How We Addressed the Matter in Our Audit	We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Partnership’s revenue recognition process. This included testing relevant controls over the review of the accounting analysis upon execution of a customer contract, as well as controls over management’s estimates affecting deferred revenue associated with shortfall billings. Our audit procedures over the Partnership’s revenue included, among others, testing a sample of revenue transactions to evaluate whether revenue was recorded in accordance with the contract terms, performing recalculations of the deferred revenue amounts related to shortfall billings, and testing management’s estimation of deferred revenue based on historical pattern of rights exercised by the customer and expected future usage.
	Sales-Type Lease Accounting
Description of the Matter	As disclosed in Note 5 of the financial statements, the Partnership entered into new agreements and amended other agreements which met the criteria of sales-type leases since the underlying assets are not expected to have an alternative use at the end of the lease terms. Under sales-type lease accounting, the lessor recognizes a net investment in the lease and derecognizes the underlying asset with the difference recorded as a gain or loss at the lease commencement date. During the year ended December 31, 2021, the Partnership recorded total net investment in the leases of $148.4 million and recognized gains on the sales-type leases totaling $24.7 million. Auditing management’s accounting for certain sales-type leases, specifically those related to lube racks constructed in prior years, was complex and highly judgmental due to the estimation uncertainty in determining the fair value of the underlying leased assets at the commencement date of the leases. The fair value of the underlying leased assets is factored into the Partnership’s determination of the net investment in the leases. The fair value estimates for these assets were sensitive to significant assumptions and inputs used based on a replacement cost valuation method, such as estimates of the replacement cost and the effective age of the assets. These assumptions have a significant effect on the fair value estimate.

- 74 -

How We Addressed the Matter in Our Audit We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Partnership's evaluation of the lease classification and related accounting for the sales-type leases. For example, we tested controls over management's review of the significant inputs and assumptions used in estimating the fair value of the underlying leased assets.
To test the Partnership’s accounting for the sales-type leases involving the previously constructed lube racks, including the estimated fair value of the underlying leased assets, we performed audit procedures that included, among others, assessing methodologies and testing the significant assumptions discussed above and the underlying data used by the Partnership in its analysis. We compared the significant replacement cost assumptions used by management to recent expenditures for similar assets. We also inspected supporting documentation, such as evidence related to maintenance records, to assess the effective age of the assets. In addition, we involved our valuation specialists to assist with our evaluation of the methodologies and significant assumptions included in the fair value estimates.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2021

Note 1:Description of Business and Summary of Significant Accounting Policies

Holly Energy Partners, L.P. (“HEP”) together with its consolidated subsidiaries, is a publicly held master limited partnership. As of December 31, 2021, HollyFrontier Corporation (“HFC”) and its subsidiaries own a 57% limited partner interest and the non-economic general partner interest in HEP. We commenced operations on July 13, 2004, upon the completion of our initial public offering. In these consolidated financial statements, the words “we,” “our,” “ours” and “us” refer to HEP unless the context otherwise indicates.

We own and operate petroleum product and crude oil pipelines, terminal, tankage and loading rack facilities and refinery processing units that support the refining and marketing operations of HFC and other refineries in the Mid-Continent, Southwest and Northwest regions of the United States. Additionally, we own a 75% interest in the UNEV Pipeline, LLC (“UNEV”), a 50% interest in Osage Pipe Line Company, LLC (“Osage”), a 50% interest in Cheyenne Pipeline LLC, and a 50% interest in Cushing Connect Pipeline & Terminal LLC.

On June 1, 2020, HFC announced plans to permanently cease petroleum refining operations at its Cheyenne refinery (the “Cheyenne Refinery”) and to convert certain assets at that refinery to renewable diesel production. HFC subsequently began winding down petroleum refining operations at the Cheyenne refinery on August 3, 2020.

On February 8, 2021, HEP and HFC finalized and executed new agreements for HEP’s Cheyenne assets with the following terms, in each case effective January 1, 2021: (1) a ten-year lease with two five-year renewal option periods for HFC’s use of certain HEP tank and rack assets in the Cheyenne refinery to facilitate renewable diesel production with an annual lease payment of approximately $5 million, (2) a five-year contango service fee arrangement that will utilize HEP tank assets inside the Cheyenne refinery where HFC will pay a base tariff to HEP for available crude oil storage and HFC and HEP will split any profits generated on crude oil contango opportunities and (3) a $10 million one-time cash payment from HFC to HEP for the termination of the existing minimum volume commitment.

On April 1, 2021, we sold our 156-mile, 6-inch refined product pipeline that connected HFC’s Navajo refinery to terminals in El Paso for gross proceeds of $7.0 million and recognized a gain on sale of $5.3 million.

We operate in two reportable segments, a Pipelines and Terminals segment and a Refinery Processing Unit segment. Disclosures around these segments are discussed in Note 16.

Our Pipelines and Terminals segment consists of:

•26 main pipeline segments

•Crude gathering networks in Texas and New Mexico

•10 refined product terminals

•1 crude terminal

•1 lube terminal

•31,800 track feet of rail storage located at two facilities

•7 locations with truck and/or rail racks

•Tankage at 6 of HFC's refining and renewable diesel facility locations

Our Refinery Processing Unit segment consists of five refinery processing units at two of HFC's refining facility locations.

We generate revenues by charging tariffs for transporting petroleum products and crude oil through our pipelines, by charging fees for terminalling and storing refined products and other hydrocarbons, providing other services at our storage tanks and terminals and by charging fees for processing hydrocarbon feedstocks through our refinery processing units. We do not take ownership of products that we transport, terminal, store or process, and therefore, we are not exposed directly to changes in commodity prices.

Principles of Consolidation

The consolidated financial statements include our accounts and those of subsidiaries and joint ventures that we control through an ownership interest greater than 50% or through a controlling financial interest with respect to variable interest entities. All

- 80 -

significant intercompany transactions and balances have been eliminated. Certain prior period balances have been reclassified for consistency with current year presentation.

Use of Estimates

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Cash and Cash Equivalents

For purposes of the statements of cash flows, we consider all highly liquid investments with maturities of three months or less at the time of purchase to be cash equivalents. The carrying amounts reported on the balance sheets approximate fair value due to the short-term maturity of these instruments.

Accounts Receivable

The majority of the accounts receivable are due from affiliates of HFC or independent companies in the petroleum industry. Credit is extended based on evaluation of the customer's financial condition, and in certain circumstances, collateral such as letters of credit or guarantees, may be required. We reserve for doubtful accounts based on our historical loss experience as well as expected credit losses from current economic conditions and management’s expectations of future economic conditions. Credit losses are charged to the allowance for doubtful accounts when an account is deemed uncollectible and historically have been minimal.

Properties and Equipment

Properties and equipment are stated at cost. Properties and equipment acquired from HFC while under common control of HFC are stated at HFC's historical basis. Depreciation is provided by the straight-line method over the estimated useful lives of the assets, primarily 15 to 25 years for terminal facilities and tankage, 25 to 30 years for pipelines, 25 years for refinery processing units and 3 to 10 years for corporate and other assets. We depreciate assets acquired under capital leases over the lesser of the lease term or the economic life of the assets. Maintenance, repairs and minor replacements are expensed as incurred. Costs of replacements constituting improvements are capitalized.

Intangible Assets

Intangible assets include transportation agreements and acquired customer relationship intangible assets. Intangible assets are stated at acquisition date fair value and are being amortized over their useful lives using the straight-line method.

Goodwill and Long-Lived Assets

Goodwill represents the excess of our cost of an acquired business over the fair value of the assets acquired, less liabilities assumed. Goodwill is not amortized. We test goodwill at the reporting unit level for impairment annually and between annual tests if events or changes in circumstances indicate the carrying amount may exceed fair value. Our goodwill impairment testing first entails a comparison of our reporting unit fair values relative to their respective carrying values, including goodwill. If carrying value exceeds the estimated fair value for a reporting unit, we measure goodwill impairment as the excess of the carrying amount of the reporting unit over the estimated fair value of the reporting unit.

The changes due to our new agreements with HFC related to our Cheyenne assets resulted in an increase in the net book value of our Cheyenne reporting unit during the first quarter of 2021 due to sales-type lease accounting, which led us to determine indicators of potential goodwill impairment for our Cheyenne reporting unit were present. Therefore, we performed an interim quantitative review of our Cheyenne reporting unit goodwill for the first quarter of 2021.

The estimated fair value of our Cheyenne reporting unit was derived using a combination of income and market approaches. The income approach reflects expected future cash flows based on anticipated gross margins, operating costs, and capital expenditures. The market approaches include both the guideline public company and guideline transaction methods. Both methods utilize pricing multiples derived from historical market transactions of other like-kind assets. These fair value measurements involve significant unobservable inputs (Level 3 inputs). See Note 6 for further discussion of Level 3 inputs.

Our interim impairment testing of our Cheyenne reporting unit goodwill identified an impairment charge of $11.0 million, which was recorded in the three months ended March 31, 2021.

- 81 -

Our annual goodwill impairment testing for 2021 and 2019 was performed on a qualitative basis during the third quarters of 2021 and 2019. We assessed qualitative factors such as macroeconomic conditions, industry considerations, cost factors and reporting unit financial performance and determined it was not more likely than not that the fair value of our reporting units were less than the respective carrying value. Therefore, in accordance with GAAP, further testing was not required.

Our annual impairment testing for 2020 was performed on a quantitative basis during the third quarter of 2020. The estimated fair value of our reporting units were derived using a combination of both income and market approaches as described above. Our annual testing of goodwill in 2020 identified an impairment charge of $35.7 million, which was recorded in the third quarter of 2020, related to our Cheyenne reporting unit.

The following is a summary of our goodwill balances:

	December 31, 2021		December 31, 2020
	(In thousands)
Goodwill	$	270,336	$	270,336
Accumulated impairment losses	(46,686)		(35,652)
	$	223,650	$	234,684

We evaluate long-lived assets, including finite-lived intangible assets, for potential impairment by identifying whether indicators of impairment exist and, if so, assessing whether the long-lived assets are recoverable from estimated future undiscounted cash flows. The actual amount of impairment loss, if any, to be recorded is equal to the amount by which a long-lived asset’s carrying value exceeds its fair value.

Investment in Equity Method Investments

We account for our interests in noncontrolling joint venture interests using the equity method of accounting, whereby we record our pro-rata share of earnings of these companies, and contributions to and distributions from the joint ventures as adjustments to our investment balances. The difference between the cost of an investment and our proportionate share of the underlying equity in net assets recorded on the investee's books is allocated to the various assets and liabilities of the equity method investment.

The following table summarizes our recorded investments compared to our share of underlying equity for each investee. We are amortizing the differences as adjustments to our pro-rata share of earnings over the useful lives of the underlying assets of these joint ventures.

Cushing Connect Terminal Holdings LLC	54,049		39,456		14,593
Total	$	93,196	$	120,544	$	(27,348)

Asset Retirement Obligations

We record legal obligations associated with the retirement of certain of our long-lived assets that result from the acquisition, construction, development and/or the normal operation of our long-lived assets. The fair value of the estimated cost to retire a tangible long-lived asset is recorded in the period in which the liability is incurred and when a reasonable estimate of the fair value of the liability can be made. For our pipeline assets, the right-of-way agreements typically do not require the dismantling, removal and reclamation of the right-of-way upon cessation of the pipeline service. Additionally, management is unable to predict when, or if, our pipelines and related facilities would become obsolete and require decommissioning. Accordingly, we have recorded no liability or corresponding asset related to an asset retirement obligation for the majority of our pipelines as both the amounts and timing of such potential future costs are indeterminable. For our remaining assets, at December 31, 2021 and 2020, we have asset retirement obligations of $8.7 million and $9.0 million, respectively, that are recorded under “Other long-term liabilities” in our consolidated balance sheets.

Class B Unit

Under the terms of the transaction to acquire HFC's 75% interest in UNEV, we issued HFC a Class B unit comprising a noncontrolling equity interest in a wholly-owned subsidiary subject to redemption to the extent that HFC is entitled to a 50% interest in our share of annual UNEV earnings before interest, income taxes, depreciation, and amortization above $30 million beginning July 1, 2015, and ending in June 2032, subject to certain limitations. Such contingent redemption payments are limited to the unredeemed value of the Class B Unit. However, to the extent earnings thresholds are not achieved, no redemption payments are required. No redemption payments have been required to date.

Pursuant to the terms of the transaction agreements, the Class B unit increases by the amount of each foregone incentive distribution and by a 7% factor compounded annually on the outstanding unredeemed balance through its expiration date. At our option, we may redeem, in whole or in part, the Class B unit at the current unredeemed value based on the calculation described. The Class B unit had a carrying value of $56.5 million at December 31, 2021, and $52.9 million at December 31, 2020.

Revenue Recognition

Revenues are generally recognized as products are shipped through our pipelines and terminals, feedstocks are processed through our refinery processing units or other services are rendered. The majority of our contracts with customers meet the definition of a lease since (1) performance of the contracts is dependent on specified property, plant, or equipment and (2) it is remote that one or more parties other than the customer will take more than a minor amount of the output associated with the specified property, plant, or equipment. Prior to the adoption of the new lease standard (see below), we bifurcated the consideration received between lease and service revenue. The new lease standard allows the election of a practical expedient whereby a lessor does not have to separate non-lease (service) components from lease components under certain conditions. The majority of our contracts meet these conditions, and we have made this election for those contracts. Under this practical expedient, we treat the combined components as a single performance obligation in accordance with Accounting Standards Codification (“ASC”) 606, which largely codified ASU 2014-09, if the non-lease (service) component is the dominant component. If the lease component is the dominant component, we treat the combined components as a lease in accordance with ASC 842, which largely codified ASU 2016-02.

Several of our contracts include incentive or reduced tariffs once a certain quarterly volume is met. Revenue from the variable element of these transactions is recognized based on the actual volumes shipped as it relates specifically to rendering the services during the applicable quarter.

- 83 -

The majority of our long-term transportation contracts specify minimum volume requirements, whereby, we bill a customer for a minimum level of shipments in the event a customer ships below their contractual requirements. If there are no future performance obligations, we will recognize these deficiency payments in revenue.

In certain of these throughput agreements, a customer may later utilize such shortfall billings as credit towards future volume shipments in excess of its minimum levels within its respective contractual shortfall make-up period. Such amounts represent an obligation to perform future services, which may be initially deferred and later recognized as revenue based on estimated future shipping levels, including the likelihood of a customer’s ability to utilize such amounts prior to the end of the contractual shortfall make-up period. We recognize these deficiency payments in revenue when we do not expect we will be required to satisfy these performance obligations in the future based on the pattern of rights projected to be exercised by the customer. During the years ended December 31, 2021, 2020 and 2019, we recognized $17.5 million, $20.8 million and $16.0 million, respectively, of these deficiency payments in revenue, of which $0.5 million, $0.7 million and $0.6 million, respectively, related to deficiency payments billed in prior periods. As of December 31, 2021, deferred revenue reflected in our consolidated balance sheet related to shortfalls billed was $4.2 million.

We have other cost reimbursement provisions in our throughput/storage agreements providing that customers (including HFC) reimburse us for certain costs. Such reimbursements are recorded as revenue or deferred revenue depending on the nature of the cost. Deferred revenue is recognized over the remaining contractual term of the related throughput agreement.

Taxes billed and collected from our pipeline and terminal customers are recorded on a net basis with no effect on net income.

Leases

We adopted ASC 842 effective January 1, 2019, and elected to adopt using the modified retrospective transition method and practical expedients, both of which are provided as options by the standard and further defined below.

Lessee Accounting - At inception, we determine if an arrangement is or contains a lease. Right-of-use assets represent our right to use an underlying asset for the lease term, and lease liabilities represent our payment obligation under the leasing arrangement. Right-of-use assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. We use our estimated incremental borrowing rate (“IBR”) to determine the present value of lease payments as most of our leases do not contain an implicit rate. Our IBR represents the interest rate which we would pay to borrow, on a collateralized basis, an amount equal to the lease payments over a similar term in a similar economic environment. We use the implicit rate when readily determinable.

Operating leases are recorded in operating lease right-of-use assets and current and noncurrent operating lease liabilities on our consolidated balance sheet. Finance leases are included in properties and equipment, current finance lease liabilities and noncurrent finance lease liabilities on our consolidated balance sheet.

When renewal options are defined in a lease, our lease term includes an option to extend the lease when it is reasonably certain we will exercise that option. Leases with a term of 12 months or less are not recorded on our balance sheet, and lease expense is accounted for on a straight-line basis. In addition, as a lessee, we separate non-lease components that are identifiable and exclude them from the determination of net present value of lease payment obligations.

Lessor Accounting - Customer contracts that contain leases are generally classified as either operating leases, direct finance leases or sales-type leases. We consider inputs such as the lease term, fair value of the underlying asset and residual value of the underlying assets when assessing the classification.

Environmental Costs

Environmental costs are expensed if they relate to an existing condition caused by past operations and do not contribute to current or future revenue generation. Liabilities are recorded when site restoration and environmental remediation, cleanup and other obligations are either known or considered probable and can be reasonably estimated. Such estimates require judgment with respect to costs, time frame and extent of required remedial and clean-up activities and are subject to periodic adjustments based on currently available information.

Under the Omnibus Agreement and certain transportation agreements and purchase agreements with HFC, HFC has agreed to indemnify us, subject to certain monetary and time limitations, for environmental noncompliance and remediation liabilities associated with certain assets transferred to us from HFC occurring or existing prior to the date of such transfers. We have an

- 84 -

environmental agreement with Delek with respect to pre-closing environmental costs and liabilities relating to the pipelines and terminals acquired from Delek in 2005, under which Delek will indemnify us subject to certain monetary and time limitations. Environmental costs recoverable through insurance, indemnification agreements or other sources are included in other assets to the extent such recoveries are considered probable.

Income Tax

We are subject to the Texas margin tax that is based on our Texas sourced taxable margin. The tax is calculated by applying a tax rate to a base that considers both revenues and expenses and therefore has the characteristics of an income tax.

We are organized as a pass-through entity for U.S. federal income tax purposes. As a result, our partners are responsible for U.S. federal income taxes based on their respective share of taxable income.

Net income for financial statement purposes may differ significantly from taxable income reportable to unitholders as a result of differences between the tax basis and financial reporting basis of assets and liabilities and the taxable income allocation requirements under the partnership agreement.

Accounting Pronouncement Adopted During the Periods Presented

Goodwill Impairment Testing

In January 2017, Accounting Standard Update (“ASU”) 2017-04, “Simplifying the Test for Goodwill Impairment,” was issued amending the testing for goodwill impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measured a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under this standard, goodwill impairment is measured as the excess of the carrying amount of the reporting unit over the related fair value. We adopted this standard effective in the second quarter of 2019, and the adoption of this standard had no effect on our financial condition, results of operations or cash flows for the year ended December 31, 2019.

Leases

In February 2016, ASU No. 2016-02, “Leases” (“ASC 842”) was issued requiring leases to be measured and recognized as a lease liability, with a corresponding right-of-use asset on the balance sheet. We adopted this standard effective January 1, 2019, and we elected to adopt using the modified retrospective transition method, whereby comparative prior period financial information will not be restated and will continue to be reported under the lease accounting standard in effect during those periods. We also elected practical expedients provided by the new standard, including the package of practical expedients and the short-term lease recognition practical expedient, which allows an entity to not recognize on the balance sheet leases with a term of 12 months or less. Upon adoption of this standard, we recognized $78.4 million of lease liabilities and corresponding right-of-use assets on our consolidated balance sheet. See Notes 4 and 5 of Notes to the Consolidated Financial Statements for additional information on our lease policies.

Credit Losses Measurement

In June 2016, ASU 2016-13, “Measurement of Credit Losses on Financial Instruments,” was issued requiring measurement of all expected credit losses for certain types of financial instruments, including trade receivables, held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. This standard was effective January 1, 2020. Adoption of the standard did not have a material impact on our financial condition, results of operations or cash flows.

Accounting Pronouncements - Not Yet Adopted

In October 2021, Accounting Standards Update 2021-08, “Accounting for Contract Assets and Contract Liabilities from Contracts with Customers” was issued requiring that an acquiring entity recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Accounting Standards Codification (“ASC”) 606 – Revenue from Contracts with Customers. This standard is effective for fiscal years beginning after December 15, 2022, and early adoption is permitted. We will evaluate the impact of this standard and consider early adoption, if applicable.

Note 2:Sinclair Acquisition

HEP Transaction

On August 2, 2021, HEP, The Sinclair Companies (“Sinclair”) and Sinclair Transportation Company, a wholly owned subsidiary of Sinclair (“STC”), entered into a Contribution Agreement (the “Contribution Agreement”) pursuant to which HEP will acquire all of the outstanding shares of STC in exchange for 21 million newly issued common units of HEP and cash consideration equal to $325 million (the “HEP Transaction”). On the same date, HFC, Sinclair and certain other parties entered into a Business Combination Agreement pursuant to which Sinclair will contribute all of the equity interests of Hippo Holding LLC, which owns Sinclair Oil Corporation, to a new HFC parent holding company that will be named “HF Sinclair Corporation” in exchange for 60,230,036 shares of common stock in HF Sinclair Corporation (the “HFC Transaction”, and together with the HEP Transaction, the “Sinclair Transactions”).

The cash consideration for the HEP Transaction is subject to customary adjustments at closing for working capital of STC. The number of HEP common units to be issued to Sinclair at closing is subject to downward adjustment if, as a condition to obtaining antitrust clearance for the Sinclair Transactions, HEP agrees to divest a portion of its equity interest in UNEV Pipeline, LLC and the sales price for such interests does not exceed the threshold provided in the Contribution Agreement.

The Contribution Agreement contains customary representations, warranties and covenants of HEP, Sinclair, and STC. The HEP Transaction is expected to close in 2022, subject to the satisfaction or waiver of certain customary conditions, including, among others, the receipt of certain required regulatory consents and clearance, including the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act (the “HSR Act”), and the consummation of the HFC Transaction. On August 23, 2021, each of HFC and Sinclair filed its respective premerger notification and report regarding the Sinclair Transactions with the U.S. Department of Justice and the U.S. Federal Trade Commission (the “FTC”) under the HSR Act. On September 22, 2021, HFC and Sinclair each received a request for additional information and documentary material (“Second Request”) from the FTC in connection with the FTC’s review of the Sinclair Transactions. Issuance of the Second Request extends the waiting period under the HSR Act until 30 days after both HFC and Sinclair have substantially complied with the Second Request, unless the waiting period is terminated earlier by the FTC or the parties otherwise commit not to close the Sinclair Transactions for some additional period of time. HFC and Sinclair are cooperating with the FTC staff in its review and are working diligently to satisfy the closing conditions as soon as possible.

The Contribution Agreement automatically terminates if the HFC Transaction is terminated, and contains other customary termination rights, including a termination right for each of HEP and Sinclair if, under certain circumstances, the closing does not occur by May 2, 2022 (the “Outside Date”), except that the Outside Date can be extended by either party by up to two 90 day periods to obtain any required antitrust clearance.

Upon closing of the HEP Transaction, HEP’s existing senior management team will continue to operate HEP. Under the definitive agreements, Sinclair will be granted the right to nominate one director to the HEP board of directors at the closing. The Sinclair stockholders have also agreed to certain customary lock-up restrictions and registration rights for the HEP common units to be issued to the stockholders of Sinclair. HEP will continue to operate under the name Holly Energy Partners, L.P.

See Note 12 for a description of the Letter Agreement between HFC and HEP entered into in connection with the Contribution Agreement.

Note 3:Investment in Joint Venture

On October 2, 2019, HEP Cushing LLC (“HEP Cushing”), a wholly-owned subsidiary of HEP, and Plains Marketing, L.P. (“PMLP”), a wholly-owned subsidiary of Plains All American Pipeline, L.P. (“Plains”), formed a 50/50 joint venture, Cushing Connect Pipeline & Terminal LLC (the “Cushing Connect Joint Venture”), for (i) the development and construction of a new 160,000 barrel per day common carrier crude oil pipeline (the “Cushing Connect Pipeline”) that connected the Cushing, Oklahoma crude oil hub to the Tulsa, Oklahoma refining complex owned by a subsidiary of HFC and (ii) the ownership and operation of 1.5 million barrels of crude oil storage in Cushing, Oklahoma (the “Cushing Connect JV Terminal”). The Cushing Connect JV Terminal went in service during the second quarter of 2020, and the Cushing Connect Pipeline was placed into service during the third quarter of 2021. Long-term commercial agreements were entered into to support the Cushing Connect Joint Venture assets.

The Cushing Connect Joint Venture contracted with an affiliate of HEP to manage the construction and operation of the Cushing Connect Pipeline and with an affiliate of Plains to manage the operation of the Cushing Connect JV Terminal. The total Cushing Connect Joint Venture investment will generally be shared equally among the partners. However, we are solely responsible for any Cushing Connect Pipeline construction costs that exceed the budget by more than 10%. HEP estimates its share of the cost of the Cushing Connect JV Terminal contributed by Plains and Cushing Connect Pipeline construction costs are approximately $70 million to $75 million, including $4 million to $6 million of Cushing Connect Pipeline construction costs exceeding the budget by more than 10% to be borne solely by HEP.

The Cushing Connect Joint Venture legal entities are variable interest entities (“VIEs”) as defined under GAAP. A VIE is a legal entity if it has any one of the following characteristics: (i) the entity does not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support; (ii) the at risk equity holders, as a group, lack the characteristics of a controlling financial interest; or (iii) the entity is structured with non-substantive voting rights. The Cushing Connect Joint Venture legal entities did not have sufficient equity at risk to finance their activities without additional financial support. Since HEP constructed and is operating the Cushing Connect Pipeline, HEP has more ability to direct the activities that most significantly impact the financial performance of the Cushing Connect Joint Venture and Cushing Connect Pipeline legal entities. Therefore, HEP consolidates those legal entities. We do not have the ability to direct the activities that most significantly impact the Cushing Connect JV Terminal legal entity, and therefore, we account for our interest in the Cushing Connect JV Terminal legal entity using the equity method of accounting. HEP's maximum exposure to loss as a result of its involvement with the Cushing Connect JV Terminal legal entity is not expected to be material due to the long-term terminalling agreements in place to support its operations.

With the exception of the assets of HEP Cushing, creditors of the Cushing Connect Joint Venture legal entities have no recourse to our assets. Any recourse to HEP Cushing would be limited to the extent of HEP Cushing's assets, which other than its investment in Cushing Connect Joint Venture, are not significant. Furthermore, our creditors have no recourse to the assets of the Cushing Connect Joint Venture legal entities.

Note 4:Revenues

Revenues are generally recognized as products are shipped through our pipelines and terminals, feedstocks are processed through our refinery processing units or other services are rendered. See Note 1 for further discussion of revenue recognition.

Disaggregated revenues are as follows:

	Years Ended December 31,
	2021		2020		2019
	(In thousands)
Pipelines	$	263,110	$	265,834	$	292,631
Terminals, tanks and loading racks	142,267		151,692		160,467
Refinery processing units	89,118		80,322		79,679
	$	494,495	$	497,848	$	532,777

- 87 -

Affiliates and third parties revenues on our consolidated statements of income were composed of the following lease and service revenues:

	Years Ended December 31,
	2021		2020		2019
	(In thousands)
Lease revenues	$	336,062	$	360,598	$	378,311
Service revenues	158,433		137,250		154,466
	$	494,495	$	497,848	$	532,777

A contract liability exists when an entity is obligated to perform future services to a customer for which the entity has received consideration. Since HEP may be required to perform future services for these deficiency payments received, the deferred revenues on our balance sheets were considered contract liabilities. A contract asset exists when an entity has a right to consideration in exchange for goods or services transferred to a customer. Our consolidated balance sheets included the contract assets and liabilities in the table below.

	December 31, 2021		December 31, 2020
	(In thousands)
Contract assets	$	6,637	$	6,306
Contract liabilities	$	(4,185)	$	(500)

The contract assets and liabilities include both lease and service components. During the years ended December 31, 2021 and 2020, we recognized $0.5 million and $0.7 million, respectively, of revenue that was previously included in contract liability as of December 31, 2020 and 2019, respectively. During the twelve months ended December 31, 2021, 2020 and 2019, we also recognized $0.3 million and $0.6 million and $3.9 million, respectively, of revenue included in contract assets at December 31, 2021.

As of December 31, 2021, we expect to recognize $1.6 billion in revenue related to our unfulfilled performance obligations under the terms of our long-term throughput agreements and operating leases expiring in 2022 through 2036. These agreements provide for changes in the minimum revenue guarantees annually for increases or decreases in the Producer Price Index (“PPI”) or Federal Energy Regulatory Commission (“FERC”) index, with certain contracts having provisions that limit the level of the rate increases or decreases. We expect to recognize revenue for these unfulfilled performance obligations as shown in the table below (amounts shown in table include both service and lease revenues):

Years Ending December 31,	(In millions)
2022	312
2023	275
2024	238
2025	172
2026	157
Thereafter	484
Total	$	1,638

Payment terms under our contracts with customers are consistent with industry norms and are typically payable within 10 to 30 days of the date of invoice.

- 88 -

Note 5:Leases

We adopted ASC 842 effective January 1, 2019, and elected to adopt using the modified retrospective transition method and practical expedients, both of which are provided as options by the standard and further defined in Note 1. See Note 1 for further discussion of lease accounting.

Lessee Accounting

As a lessee, we lease land, buildings, pipelines, transportation and other equipment to support our operations. These leases can be categorized into operating and finance leases.

Our leases have remaining terms of less than 1 year to 23 years, some of which include options to extend the leases for up to 10 years.

Finance Lease Obligations

We have finance lease obligations related to vehicle leases with initial terms of 33 to 48 months. The total cost of assets under finance leases was $6.0 million and $6.4 million as of December 31, 2021 and December 31, 2020, respectively, with accumulated depreciation of $3.6 million and $3.4 million as of December 31, 2021 and December 31, 2020, respectively. We include depreciation of finance leases in depreciation and amortization in our consolidated statements of income.

In addition, we have a finance lease obligation related to a pipeline lease with an initial term of 10 years with one remaining subsequent renewal option for an additional 10 years.

Lessor Accounting

As discussed in Note 1, the majority of our contracts with customers meet the definition of a lease. See Note 1 for further discussion of the impact of adoption of this standard on our activities as a lessor.

Substantially all of the assets supporting contracts meeting the definition of a lease have long useful lives, and we believe these assets will continue to have value when the current agreements expire due to our risk management strategy for protecting the residual fair value of the underlying assets by performing ongoing maintenance during the lease term. HFC generally has the option to purchase assets located within HFC refinery boundaries, including refinery tankage, truck racks and refinery processing units, at fair market value when the related agreements expire.

During the year ended December 31, 2021, we entered into new agreements, and amended other agreements, with HFC related to our Cheyenne assets, Tulsa West lube racks, various crude tanks and new Navajo tanks, and the agreements we previously entered into relating to the Cushing Connect Pipeline became effective. These agreements met the criteria of sales-type leases since the underlying assets are not expected to have an alternative use at the end of the lease terms to anyone other than HFC. Under sales-type lease accounting, at the commencement date, the lessor recognizes a net investment in the lease, based on the estimated fair value of the underlying leased assets at contract inception, and derecognizes the underlying assets with the difference recorded as selling profit or loss arising from the lease. Therefore, we recognized a gain on sales-type leases during the year ended December 31, 2021 composed of the following:

- 91 -

	(In thousands)
Net investment in leases	$	148,419
Properties and equipment, net	(130,301)
Deferred Revenue	6,559
Gain on sales-type leases	$	24,677

During the year ended December 31, 2020, one of our throughput agreements with Delek US Holdings, Inc. (“Delek”) was partially renewed. A component of this agreement met the criteria of a sales-type lease since the underlying asset is not expected to have an alternative use at the end of the lease term to anyone other than Delek. We recognized a gain on sales-type leases during the year ended December 31, 2020 composed of the following:

	(In thousands)
Net investment in leases	$	35,319
Properties and equipment, net	(1,485)
Gain on sales-type leases	$	33,834

These sales-type lease transactions, including the related gains, were non-cash transactions.

Lease income recognized was as follows:

	Years Ended December 31,
	2021		2020
	(In thousands)
Operating lease revenues	$	326,902	$	350,668
Direct financing lease interest income	2,089		2,096
Gain on sales-type leases	24,677		33,834
Sales-type lease interest income	27,836		8,481
Lease revenues relating to variable lease payments not included in measurement of the sales-type lease receivable	9,160		9,929

For our sales-type leases, we included customer obligations related to minimum volume requirements in guaranteed minimum lease payments. Portions of our minimum guaranteed pipeline tariffs for assets subject to sales-type lease accounting are recorded as interest income with the remaining amounts recorded as a reduction in net investment in leases. We recognized any billings for throughput volumes in excess of minimum volume requirements as variable lease payments, and these variable lease payments were recorded in lease revenues.

- 92 -

Annual minimum undiscounted lease payment receipts under our leases were as follows as of December 31, 2021:

Note 6:Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are derived using inputs (assumptions that market participants would use in pricing an asset or liability) including assumptions about risk. GAAP categorizes inputs used in fair value measurements into three broad levels as follows:

•(Level 1) Quoted prices in active markets for identical assets or liabilities.

•(Level 2) Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, similar assets and liabilities in markets that are not active or can be corroborated by observable market data.

•(Level 3) Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes valuation techniques that involve significant unobservable inputs.

Financial Instruments

Our financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, and debt. The carrying amounts of cash equivalents, accounts receivable and accounts payable approximate fair value due to the short-term maturity of these instruments. Debt consists of outstanding principal under our revolving credit agreement (which approximates fair value as interest rates are reset frequently at current interest rates) and our fixed interest rate senior notes.

- 93 -

The carrying amounts and estimated fair values of our senior notes were as follows:

		December 31, 2021				December 31, 2020
Financial Instrument	Fair Value Input Level	Carrying Value		Fair Value		Carrying Value		Fair Value
		(In thousands)
Liabilities:
5% Senior Notes	Level 2	$	493,049	$	502,705	$	492,103	$	506,540

Level 2 Financial Instruments

Our senior notes are measured at fair value using Level 2 inputs. The fair value of the senior notes is based on market values provided by a third-party bank, which were derived using market quotes for similar type debt instruments. See Note 10 for additional information.

Non-Recurring Fair Value Measurements

For gains on sales-type leases recognized during the years ended December 31, 2021 and 2020, the estimated fair value of the underlying leased assets at contract inception and the present value of the estimated unguaranteed residual asset at the end of the lease term are used in determining the net investment in leases and related gain on sales-type leases recorded. The asset valuation estimates include Level 3 inputs based on a replacement cost valuation method.

During the years ended December 31, 2021 and 2020, we recognized goodwill impairment based on fair value measurements utilized during our goodwill testing (see Note 1). The fair value measurements were based on a combination of valuation methods including discounted cash flows and the guideline public company and guideline transaction methods; all of which are Level 3 inputs.

Note 7:Properties and Equipment 

The carrying amounts of our properties and equipment are as follows:

	December 31, 2021		December 31, 2020
	(In thousands)
Pipelines, terminals and tankage	$	1,527,697	$	1,575,815
Refinery assets	348,882		348,882
Land and right of way	98,837		87,076
Construction in progress	26,446		58,467
Other	48,203		46,201
	2,050,065		2,116,441
Less accumulated depreciation	(721,037)		(665,756)
	$	1,329,028	$	1,450,685

Depreciation expense was $79.2 million, $85.0 million, and $82.6 million for the years ended December 31, 2021, 2020 and 2019, respectively, and includes depreciation of assets acquired under capital leases. Asset abandonment charges of $1.1 million, $1.0 million and $1.3 million for assets permanently removed from service were included in depreciation expense for the years ended December 31, 2021, 2020 and 2019, respectively.

Note 8:Intangible Assets

Intangible assets include transportation agreements and customer relationships that represent a portion of the total purchase price of certain assets acquired from Delek in 2005, from HFC in 2008 prior to HEP becoming a consolidated VIE of HFC, from Plains in 2017, and from other minor acquisitions in 2018.

- 94 -

The carrying amounts of our intangible assets are as follows:

	Useful Life	December 31, 2021		December 31, 2020
		(In thousands)
Delek transportation agreement	30 years	$	59,933	$	59,933
HFC transportation agreements	10-15 years	75,131		75,131
Customer relationships	10 years	69,683		69,683
Other	20 years	50		50
		204,797		204,797
Less accumulated amortization		(131,490)		(117,482)
Intangible assets, net		$	73,307	$	87,315

Amortization expense was $14.0 million for the years ended December 31, 2021, 2020 and 2019, respectively. We estimate amortization expense to be $14.0 million for 2022, $9.9 million for 2023, and $9.1 million for 2024, 2025, and 2026.

We have additional transportation agreements with HFC resulting from historical transactions consisting of pipeline, terminal and tankage assets contributed to us or acquired from HFC. These transactions occurred while we were a consolidated variable interest entity of HFC; therefore, our basis in these agreements is zero and does not reflect a step-up in basis to fair value.

Note 9: Employees, Retirement and Incentive Plans

Direct support for our operations is provided by Holly Logistic Services, L.L.C., (“HLS”), an HFC subsidiary, which utilizes personnel employed by HFC who are dedicated to performing services for us. Their costs, including salaries, bonuses, payroll taxes, benefits and other direct costs, are charged to us monthly in accordance with an omnibus agreement that we have with HFC. These employees participate in the retirement and benefit plans of HFC. Our share of retirement and benefit plan costs was $8.7 million, $7.9 million and $7.3 million for the years ended December 31, 2021, 2020 and 2019, respectively. These costs include retirement costs of $3.7 million, $3.4 million and $3.4 million for the years ended December 31, 2021, 2020 and 2019, respectively.

Under HLS’s secondment agreement with HFC (the “Secondment Agreement”), certain employees of HFC are seconded to HLS to provide operational and maintenance services for certain of our processing, refining, pipeline and tankage assets, and HLS reimburses HFC for its prorated portion of the wages, benefits, and other costs related to these employees.

We have a Long-Term Incentive Plan for employees and non-employee directors who perform services for us. The Long-Term Incentive Plan consists of five components: restricted or phantom units, performance units, unit options, unit appreciation rights and cash awards. Our accounting policy for the recognition of compensation expense for awards with pro-rata vesting (a significant proportion of our awards) is to expense the costs ratably over the vesting periods.

As of December 31, 2021, we have two types of unit-based awards outstanding, which are described below. The compensation cost charged against income was $2.6 million, $2.2 million and $2.5 million for the years ended December 31, 2021, 2020 and 2019, respectively. We currently purchase units in the open market instead of issuing new units for settlement of all unit awards under our Long-Term Incentive Plan. As of December 31, 2021, 2,500,000 units were authorized to be granted under our Long-Term Incentive Plan, of which 753,425 have not yet been granted, assuming no forfeitures of the unvested units and full achievement of goals for the unvested performance units.

Phantom Units

Under our Long-Term Incentive Plan, we grant phantom units to non-employee directors and selected employees who perform services for us, with most awards vesting over a period of one to three years. Although full ownership of the units does not transfer to the recipients until the units vest, the recipients have distribution rights on these units from the date of grant.

The fair value of each phantom unit award is measured at the market price as of the date of grant and is amortized on a straight-line basis over the requisite service period for each separately vesting portion of the award.

- 95 -

A summary of phantom unit activity and changes during the year ended December 31, 2021, is presented below: 

Phantom Units	Units	Weighted- Average Grant-Date Fair Value
Outstanding at January 1, 2021 (nonvested)	295,992	$	14.48
Granted	51,670	18.93
Vesting and transfer of common units to recipients	(137,566)	15.56
Forfeited	(6,833)	15.54
Outstanding at December 31, 2021 (nonvested)	203,263	14.85

The grant date fair values of restricted or phantom units that were vested and transferred to recipients during the years ended December 31, 2021, 2020 and 2019 were $2.1 million, $2.0 million and $2.1 million, respectively. As of December 31, 2021, there was $1.8 million of total unrecognized compensation expense related to unvested phantom unit grants, which is expected to be recognized over a weighted-average period of 1.4 years. For the years ended December 31, 2020 and 2019, the grant date price applied to the number of restricted or phantom units awarded was $11.92 and $23.52, respectively.

Performance Units

Under our Long-Term Incentive Plan, we grant performance units to selected executives who perform services for us. Performance units granted are payable in common units at the end of a three-year performance period based upon meeting certain criteria over the performance period. Under the terms of our performance unit grants, some awards are subject to the growth in our distributable cash flow per common unit over the performance period while other awards are subject to “financial performance” and “market performance.” Financial performance is based on meeting certain earnings before interest, taxes, depreciation and amortization (“EBITDA”) targets, while market performance is based on the relative standing of total unitholder return achieved by HEP compared to peer group companies. The number of units ultimately issued under these awards can range from 0% to 200%.

Although common units are not transferred to the recipients until the performance units vest, the recipients have distribution rights with respect to the target number of performance units subject to the award from the date of grant at the same rate as distributions paid on our common units.

A summary of performance unit activity and changes for the year ended December 31, 2021, is presented below:

Performance Units	Units
Outstanding at January 1, 2021 (nonvested)	77,472
Granted	10,128
Vesting and transfer of common units to recipients	(10,881)
Outstanding at December 31, 2021 (nonvested)	76,719

The grant date fair values of performance units vested and transferred to recipients were $0.4 million, $0.4 million and $0.3 million for the years ended December 31, 2021, 2020 and 2019, respectively. Based on the weighted average fair value of performance units outstanding at December 31, 2021, of $1.4 million, there was $0.6 million of total unrecognized compensation expense related to nonvested performance units, which is expected to be recognized over a weighted-average period of 1.5 years.

During the year ended December 31, 2021, we paid $2.0 million for the purchase of our common units in the open market for the issuance and settlement of unit awards under our Long-Term Incentive Plan.

Note 10:Debt

Credit Agreement

In April 2021, we amended our senior secured revolving credit facility (the “Credit Agreement”) decreasing the size of the facility from $1.4 billion to $1.2 billion and extending the maturity date to July 27, 2025. The Credit Agreement is available to fund capital expenditures, investments, acquisitions, distribution payments, working capital and for general partnership purposes. The Credit Agreement is also available to fund letters of credit up to a $50 million sub-limit and continues to provide for an accordion feature that allows us to increase commitments under the Credit Agreement up to a maximum amount of $1.7 billion.

Our obligations under the Credit Agreement are collateralized by substantially all of our assets, and indebtedness under the Credit Agreement is guaranteed by our material, wholly-owned subsidiaries. The Credit Agreement requires us to maintain compliance with certain financial covenants consisting of total leverage, senior secured leverage, and interest coverage. It also limits or restricts our ability to engage in certain activities. If, at any time prior to the expiration of the Credit Agreement, HEP obtains two investment grade credit ratings, the Credit Agreement will become unsecured and many of the covenants, limitations, and restrictions will be eliminated.

We may prepay all loans at any time without penalty, except for tranche breakage costs. If an event of default exists under the Credit Agreement, the lenders will be able to accelerate the maturity of all loans outstanding and exercising other rights and remedies. We were in compliance with the covenants as of December 31, 2021.

Senior Notes

On February 4, 2020, we closed a private placement of $500 million in aggregate principal amount of 5% senior unsecured notes due in 2028 (the “5% Senior Notes”). On February 5, 2020, we redeemed the existing $500 million 6% Senior Notes at a redemption cost of $522.5 million, at which time we recognized a $25.9 million early extinguishment loss consisting of a $22.5 million debt redemption premium and unamortized financing costs of $3.4 million. We funded the $522.5 million redemption with proceeds from the issuance of our 5% Senior Notes and borrowings under our Credit Agreement.

The 5% Senior Notes are unsecured and impose certain restrictive covenants, including limitations on our ability to incur additional indebtedness, make investments, sell assets, incur certain liens, pay distributions, enter into transactions with affiliates, and enter into mergers. At any time when the 5% Senior Notes are rated investment grade by either Moody’s or Standard & Poor’s and no default or event of default exists, we will not be subject to many of the foregoing covenants. Additionally, we have certain redemption rights at varying premiums over face value under the 5% Senior Notes.

Indebtedness under the 5% Senior Notes is guaranteed by our wholly-owned subsidiaries (other than Holly Energy Finance Corp. and certain immaterial subsidiaries).

Note 11:Commitments and Contingencies

We lease certain facilities and pipelines under operating leases and finance leases, most of which contain renewal options. These operating leases have various termination dates through 2035. See Note 5 for a schedule of annual minimum undiscounted lease payments under our leases as of December 31, 2021. As of December 31, 2021, we expect to receive aggregate payments totaling $1.0 million over the life of our noncancelable sublease of office space, expiring in 2026.

We also have other long-term contractual obligations consisting of long-term site service agreements with HFC, expiring in 2058 through 2066, for the provision of certain facility services and utility costs that relate to our assets located at HFC’s refinery and renewable diesel facilities. We are presenting obligations for the full term of these agreements; however, the agreements can be terminated with 180 day notice if we cease to operate the applicable assets.

In addition, we have long-term contractual obligations associated with rights-of-way agreements, which have various termination dates through 2099. The related payments below include only obligations under the remaining non-cancelable terms of these agreements at December 31, 2021.

At December 31, 2021, these minimum future contractual obligations and other miscellaneous obligations having terms in excess of one year are as follows:

Thereafter	218,941
Total	$	256,210

We are a party to various legal and regulatory proceedings, none of which we believe will have a material adverse impact on our financial condition, results of operations or cash flows.

We filed a business interruption claim with our insurance carriers related to a loss at HFC's Woods Cross Refinery that occurred in the first quarter 2018. During the year ended December 31, 2020, we reached a final settlement agreement regarding the amounts owed to us pursuant to our business interruption coverage, and we recognized a gain of $7.3 million, which was included in gain on sale of assets and other on our income statement for the year ended December 31, 2020.

Note 12:Related Party Transactions

We serve HFC’s refinery and renewable diesel facilities under long-term pipeline, terminal and tankage throughput agreements, and refinery processing unit tolling agreements expiring from 2022 to 2036, and revenues from these agreements accounted for approximately 79% of our total revenues for the year ended December 31, 2021. Under these agreements, HFC agrees to transport, store, and process throughput volumes of refined product, crude oil and feedstocks on our pipelines, terminals, tankage, loading rack facilities and refinery processing units that result in minimum annual payments to us. These minimum annual payments or revenues are generally subject to annual rate adjustments on July 1st each year based on increases or decreases in the Producer Price Index (“PPI”) or FERC index. As of December 31, 2021, these agreements with HFC require minimum annualized payments to us of $352.8 million.

If HFC fails to meet its minimum volume commitments under the agreements in any quarter, it will be required to pay us the amount of any shortfall in cash by the last day of the month following the end of the quarter. Under certain of these agreements, a shortfall payment may be applied as a credit in the following four quarters after its minimum obligations are met.

Under certain provisions of the Omnibus Agreement, we pay HFC an annual administrative fee (currently $2.6 million) for the provision by HFC or its affiliates of various general and administrative services to us. This fee does not include the salaries of personnel employed by HFC who perform services for us on behalf of HLS or the cost of their employee benefits, which are charged to us separately by HFC. Also, we reimburse HFC and its affiliates for direct expenses they incur on our behalf.

Related party transactions with HFC are as follows:

•Revenues received from HFC were $390.8 million, $399.8 million and $411.8 million for the years ended December 31, 2021, 2020 and 2019, respectively.

•HFC charged us general and administrative services under the Omnibus Agreement of $2.6 million for each of the years ended December 31, 2021, 2020 and 2019.

•We reimbursed HFC for costs of employees supporting our operations of $61.2 million, $55.8 million and $55.1 million for the years ended December 31, 2021, 2020 and 2019, respectively.

•HFC reimbursed us $7.9 million, $10.0 million and $13.9 million for the years ended December 31, 2021, 2020 and 2019, respectively, for expense and capital projects.

•We distributed $83.5 million, $95.2 million and $150.0 million in the years ended December 31, 2021, 2020 and 2019 respectively, to HFC as regular distributions on its common units.

•Accounts receivable from HFC were $56.2 million and $48.0 million at December 31, 2021 and 2020, respectively.

•Accounts payable to HFC were $11.7 million and $18.1 million at December 31, 2021 and 2020, respectively.

•Revenues for the years ended December 31, 2021, 2020 and 2019 include $0.4 million, $0.5 million and $0.5 million, respectively, of shortfall payments billed to HFC in 2020, 2019 and 2018, respectively. Deferred revenue in the consolidated balance sheets at December 31, 2021 and 2020, includes $4.1 million and $0.4 million, respectively, relating to certain shortfall billings to HFC.

•We received direct financing lease payments from HFC for use of our Artesia and Tulsa railyards of $2.1 million for each of the years ended December 31, 2021, 2020 and 2019 .

•We recorded a gain on sales-type leases with HFC of $24.7 million and $35.2 million during the year ended December 31, 2021 and December 31, 2019, respectively, and we received sales-type lease payments of $28.9 million, $9.5 million and $4.8 million from HFC that were not included in revenues for the years ended December 31, 2021, 2020 and 2019, respectively.

•HEP and HFC reached an agreement to terminate the existing minimum volume commitments for HEP's Cheyenne assets and enter into new agreements, which were finalized and executed on February 8, 2021, with the following terms, in each case effective January 1, 2021: (1) a ten-year lease with two five-year renewal option periods for HFC’s use of certain HEP tank and rack assets in the Cheyenne refinery to facilitate renewable diesel production with an annual lease payment of approximately $5 million, (2) a five-year contango service fee arrangement that will utilize HEP tank assets inside the Cheyenne refinery where HFC will pay a base tariff to HEP for available crude oil storage

- 99 -

and HFC and HEP will split any profits generated on crude oil contango opportunities and (3) a $10 million one-time cash payment from HFC to HEP for the termination of the existing minimum volume commitment.

On August 2, 2021, in connection with the Sinclair Transactions (described in Note 2 above), HEP and HFC entered into a Letter Agreement (“Letter Agreement”) pursuant to which, among other things, HEP and HFC agreed, upon the consummation of the Sinclair Transactions, to enter into amendments to certain of the agreements by and among HEP and HFC, including the master throughput agreement, to include within the scope of such agreements the assets to be acquired by HEP pursuant to the Contribution Agreement (described in Note 2 above).

In addition, the Letter Agreement provides that if, as a condition to obtaining antitrust clearance for the Sinclair Transactions, HFC enters into a definitive agreement to divest its refinery in Davis County, Utah (the “Woods Cross Refinery”), then HEP would sell certain assets located at, or relating to, the Woods Cross Refinery to HFC in exchange for cash consideration equal to $232.5 million plus the certain accounts receivable of HEP in respect of such assets, with such sale to be effective immediately prior to the closing of the sale of the Woods Cross Refinery by HFC. The Letter Agreement also provides that HEP’s right to future revenues from HFC in respect of such Woods Cross Refinery assets will terminate at the closing of such sale.

Note 13: Partners’ Equity, Income Allocations and Cash Distributions

At December 31, 2021, HFC held 59,630,030 of our common units, constituting a 57% limited partner interest in us and held the non-economic general partner interest.

Continuous Offering Program

We have a continuous offering program under which we may issue and sell common units from time to time, representing limited partner interests, up to an aggregate gross sales amount of $200 million. As of December 31, 2021, HEP had issued 2,413,153 units under this program, providing $82.3 million in gross proceeds.

Allocations of Net Income

Net income attributable to the partners is allocated to the partners based on their weighted-average ownership percentage during the period.

Cash Distributions

We consider regular cash distributions to unitholders on a quarterly basis, although there is no assurance as to the future cash distributions since they are dependent upon future earnings, cash flows, capital requirements, financial condition and other factors.

Within 45 days after the end of each quarter, we distribute all of our available cash (as defined in our partnership agreement) to unitholders of record on the applicable record date. The amount of available cash generally is all cash on hand at the end of the quarter; less the amount of cash reserves established by our general partner to provide for the proper conduct of our business, comply with applicable laws, any of our debt instruments, or other agreements; or provide funds for distributions to our unitholders and to our general partner for any one or more of the next four quarters; plus all cash on hand on the date of determination of available cash for the quarter resulting from working capital borrowings made after the end of the quarter.

On January 21, 2022, we announced our cash distribution for the fourth quarter of 2021 of $0.35 per unit. The distribution was payable on all common units and was paid February 11, 2022, to all unitholders of record on February 1, 2022.

We paid cash distributions totaling $149.4 million, $174.4 million and $273.2 million for the years ended December 31, 2021, 2020 and 2019, respectively.

Note 14: Net Income Per Limited Partner Unit

Basic net income per unit applicable to the limited partners is calculated as net income attributable to the partners, adjusted for participating securities’ share in earnings, divided by the weighted average limited partners’ units outstanding. Diluted net

- 100 -

income per unit assumes, when dilutive, the issuance of the net incremental units from phantom units and performance units. To the extent net income attributable to the partners exceeds or is less than cash distributions, this difference is allocated to the partners based on their weighted-average ownership percentage during the period. Our dilutive securities are immaterial for all periods presented.

Net income per limited partner unit is computed as follows:

	Years Ended December 31,
	2021		2020		2019
	(In thousands, except per unit data)

Limited partners' per unit interest in earnings - basic and diluted	$	2.03	$	1.61	$	2.13

Note 15:Environmental

We expensed $1.9 million, $1.6 million and $0.5 million for the years ended December 31, 2021, 2020 and 2019, respectively, for environmental remediation obligations. The accrued environmental liability related to environmental clean-up projects for which we have assumed liability or for which indemnity provided by HFC has expired reflected in our consolidated balance sheets was $3.9 million and $4.5 million as of December 31, 2021 and 2020, respectively, of which $2.4 million and $2.5 million, respectively, were classified as other long-term liabilities. These accruals include remediation and monitoring costs expected to be incurred over an extended period of time.

Under the Omnibus Agreement and certain transportation agreements and purchase agreements with HFC, HFC has agreed to indemnify us, subject to certain monetary and time limitations, for environmental noncompliance and remediation liabilities associated with certain assets transferred to us from HFC and occurring or existing prior to the date of such transfers. As of December 31, 2021 and 2020, our consolidated balance sheets included additional accrued environmental liabilities of $0.3 million and $0.5 million for HFC indemnified liabilities, respectively, and other assets included equal and offsetting balances representing amounts due from HFC related to indemnifications for environmental remediation liabilities.

Note 16:Operating Segments

Although financial information is reviewed by our chief operating decision makers from a variety of perspectives, they view the business in two reportable operating segments: (1) pipelines and terminals and (2) refinery processing units. These segments adhere to the accounting polices used for our consolidated financial statements. For a discussion of these accounting policies and a summary of our reportable operating segments' assets and derivation of revenue, see Note 1.

Pipelines and terminals have been aggregated as one reportable segment as both pipelines and terminals (1) have similar economic characteristics, (2) similarly provide logistics services of transportation and storage of petroleum products, (3) similarly support the petroleum refining business, including distribution of its products, (4) have principally the same customers and (5) are subject to similar regulatory requirements.

We evaluate the performance of each segment based on its respective operating income. Certain general and administrative expenses and interest and financing costs are excluded from segment operating income as they are not directly attributable to a specific reportable segment. Identifiable assets are those used by the segment, whereas other assets are principally equity method investments, cash, deposits and other assets that are not associated with a specific reportable segment.

Note 17: Supplemental Guarantor/Non-Guarantor Financial Information

Obligations of HEP (“Parent”) under the 5% Senior Notes have been jointly and severally guaranteed by each of its direct and indirect 100% owned subsidiaries (“Guarantor Subsidiaries”). These guarantees are full and unconditional, subject to certain customary release provisions. These circumstances include (i) when a Guarantor Subsidiary is sold or sells all or substantially all of its assets, (ii) when a Guarantor Subsidiary is declared “unrestricted” for covenant purposes, (iii) when a Guarantor Subsidiary's guarantee of other indebtedness is terminated or released and (iv) when the requirements for legal defeasance or covenant defeasance or to discharge the senior notes have been satisfied.

Item 10. Directors, Executive Officers and Corporate Governance

Holly Logistic Services, L.L.C. (“HLS”), the general partner of HEP Logistics Holdings, L.P. (“HEP Logistics”), our general partner, manages our operations and activities. Neither our general partner nor our directors are elected by our unitholders. Unitholders are not entitled to directly or indirectly participate in our management or operations. The sole member of HLS, which is a subsidiary of HFC, appoints the directors of HLS to serve until their death, resignation or removal.

Our general partner owes a fiduciary duty to our unitholders. Our general partner is liable, as general partner, for all of our debts (to the extent not paid from our assets), except for indebtedness or other obligations that are made specifically non-recourse to it. Whenever possible, our general partner intends to incur indebtedness or other obligations that are non-recourse.

Board Leadership Structure

The Board is responsible for selecting the Board leadership structure that is in the best interest of HLS and HEP. Currently, Mr. Jennings serves as Chairperson of the Board and as the Chief Executive Officer of HLS. Independent directors and management have different perspectives and roles in strategy development. The independent directors on the Board bring experience, oversight and expertise from outside HLS, HEP and the industry, while the Chief Executive Officer brings HLS and HEP experience and expertise. The Board believes the combined role of Chairperson of the Board and Chief Executive Officer working with the lead independent director (the “Presiding Director”), is in the best interest of unitholders at this time because the combined role for HLS provides balance between strategy development and independent oversight of management, both of which are particularly useful in HLS’s role as general partner.

None of our directors reported any litigation that is required to be reported in this Annual Report on Form 10-K. There are no family relationships among any of our directors or executive officers.

Chairperson of the Board

Mr. Jennings was selected by the directors of HLS to serve as the Chairperson of the Board. The Chairperson has the following responsibilities:

•designating and calling meetings of the Board;

•presiding at all Board meetings;

•consulting with management on Board and committee meeting agendas;

•facilitating teamwork and communication between the Board and management; and

•acting as a liaison between management and the Board.

Presiding Director

Larry R. Baldwin, an independent director, was appointed by the non-management directors of HLS to serve as the Presiding Director of the Board. The Presiding Director has the following responsibilities:

•presiding at all executive sessions of the non-management directors of the Board;

•consulting with management on Board and committee meeting agendas;

•facilitating teamwork and communication between the non-management directors and management; and

•acting as a liaison in appropriate instances between management and the non-management directors, including advising the Chairperson of the Board and Chief Executive Officer on the efficiency of the Board meetings

Persons wishing to communicate with the non-employee directors are invited to email the Presiding Director at presiding.director.HEP@hollyenergy.com or write to: Larry R. Baldwin, Presiding Director, c/o Secretary, Holly Logistic Services, L.L.C., 2828 N. Harwood, Suite 1300, Dallas, Texas 75201-1507. Communications to the Board generally may be sent by certified mail to Holly Logistic Services, L.L.C., 2828 N. Harwood, Suite 1300, Dallas, Texas 75201-1507, Attention: Secretary. The Secretary will forward all communication to the appropriate director or directors, other than those communications that are merely solicitations for products or services or relate to matters that are of a type that are clearly improper or irrelevant to the functioning of the Board or the business and affairs of HLS and HEP.

- 111 -

Risk Management

The Board has an active role in overseeing management of the risks affecting HLS and HEP. The Board regularly reviews information regarding HLS and HEP’s credit, liquidity, business, operations and cybersecurity, as well as the risks associated with each. The Board committees are also engaged in overseeing risk associated with HLS and HEP.

•The Compensation Committee oversees the management of risks relating to HLS’s compensation plans and arrangements.

•The Audit Committee oversees management of financial reporting and controls risks.

•The Conflicts Committee oversees specific matters that it or the Board believes may involve conflicts of interest with HFC.

While each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire Board is ultimately responsible for the risk management of HLS and HEP and is regularly informed on these matters through committee and senior management presentations.

The sole member of HLS manages risks associated with the independence of the Board. The Board also receives input and reports from HLS’s risk management oversight committee on management’s views of the risks facing HLS and HEP. The risk management oversight committee is made up of management personnel, none of whom serve on the Board and all of whom have a range of different backgrounds, skills and experiences with regard to the operational, financial and strategic risk profile of HLS and HEP. The risk management oversight committee supports the efforts of the Board and the Board committees to monitor and evaluate guidelines and policies governing HLS’s and HEP’s risk assessment and management.

Director Qualifications

The Board believes that it is necessary for each of HLS’s directors to possess a variety of qualities and skills. When searching for new candidates, the sole member of HLS considers the evolving needs of the Board and searches for candidates that fill any current or anticipated future needs. The Board also believes that all directors must possess a considerable amount of business management, business leadership and educational experience. When considering director candidates, the sole member of HLS first considers a candidate’s management experience and then considers issues of judgment, background, stature, conflicts of interest, integrity, ethics, industry knowledge, ability to commit adequate time to the Board, and commitment to the goal of maximizing unitholder value. The sole member of HLS also focuses on issues of diversity, such as diversity of race, gender, age, culture, thought and geography. In considering candidates for the Board, the sole member of HLS considers the entirety of each candidate’s credentials in the context of these standards. All our directors bring to the Board executive leadership experience derived from their service in many areas.

Pursuant to the Governance Guidelines of HLS and HEP, a director must submit his or her resignation to the Board in the first quarter of the calendar year in which the director will attain the age of 75 or greater. If the resignation is accepted by the Board, the resignation will be effective on December 31 of the year in which the resignation was accepted by the Board.

Director Independence

The Board has determined that Larry R. Baldwin, Christine B. LaFollete, James H. Lee and Eric L. Mattson meet the applicable criteria for independence under the currently applicable rules of the New York Stock Exchange (“NYSE”). Mr. Jennings is not independent because he is an officer of HLS and an employee of HFC.

Audit Committee. The Audit Committee of HLS is currently composed of three directors, Messrs. Baldwin, Lee and Mattson. The Board has determined that each member of the Audit Committee is “independent” as defined by the NYSE listing standards and Rule 10A-3 of the Securities Exchange Act of 1934 (the “Exchange Act”).

Conflicts Committee. The Conflicts Committee of HLS is currently composed of three directors, Messrs. Baldwin and Mattson and Ms. LaFollette. The Board has determined that each member of the Conflicts Committee is “independent” as defined by the NYSE listing standards and Rule 10A-3 of the Exchange Act, as required by the Conflicts Committee Charter.

Compensation Committee. The Compensation Committee of HLS is currently composed of three directors, Messrs. Jennings and Lee and Ms. LaFollette. The Board has determined that Mr. Lee and Ms. LaFollette are “independent” as defined by the NYSE listing standards. Because we are a master limited partnership, Rule 303A.05 of the NYSE Listed Company

- 112 -

Manual, which requires a publicly traded company to have a compensation committee composed entirely of independent directors, does not apply to us.

Code of Business Conduct and Ethics

HLS has adopted a Code of Business Conduct and Ethics (the “Code”) that applies to all of its officers, directors and employees, including HLS’s principal executive officer, principal financial officer, and principal accounting officer. The purpose of the Code is to, among other things, affirm HLS’s and HEP’s commitment to a high standard of integrity and ethics. The Code sets forth a common set of values and standards to which all of HLS’s officers, directors and employees must adhere. We will post information regarding an amendment to, or a waiver from, the Code on our website.

Copies of our Governance Guidelines, Audit Committee Charter, Compensation Committee Charter, and the Code are available on our website at www.hollyenergy.com. Copies of these documents may also be obtained free of charge upon written request to Holly Energy Partners, L.P., Attention: Vice President, Investor Relations, 2828 N. Harwood, Suite 1300, Dallas, Texas, 75201-1507.

_____________________________________________________________________________________________

None of our directors reported any litigation for the period from 2012 to 2022 that is required to be reported in this Annual Report on Form 10-K. There are no family relationships among any of our directors or executive officers.

The Board

Under the Company’s Governance Guidelines, Board members are expected to prepare for, attend and participate in all meetings of the Board and Board committees on which they serve. During 2021, the Board held eleven meetings. Each director attended at least 75% of the total number of meetings of the Board and committees on which he or she served.

Board Committees

The Board currently has three standing committees:

•an Audit Committee;

•a Compensation Committee; and

•a Conflicts Committee.

Each of these committees operates under a written charter adopted by the Board.

During 2021, the Audit Committee held eight meetings, the Conflicts Committee held twenty-six meetings, and the Compensation Committee held four meetings.

The Board appoints committee members annually. The following table sets forth the current composition of our committees:

Name	Audit Committee	Compensation Committee	Conflicts Committee
Larry R. Baldwin	x (Chair)		x
Michael C. Jennings		x (Chair)
Christine B. LaFollette		x	x
James H. Lee	x	x
Eric L. Mattson	x		x (Chair)

Audit Committee

The functions of the Audit Committee pursuant to its charter include the following:

•selecting, compensating, retaining and overseeing our independent registered public accounting firm and conducting an annual review of the independence and performance of that firm;

•confirming with the independent registered public accounting firm its compliance with the partner rotation requirements established by the SEC;

•reviewing and evaluating the lead partner of the independent registered public accounting firm;

- 115 -

•reviewing the scope and the planning of the annual audit performed by the independent registered public accounting firm;

•overseeing matters related to the internal audit function;

•reviewing and discussing with the internal auditor any significant reports to management prepared by the internal auditor and any responses from management;

•reviewing the audit report issued by the independent registered public accounting firm;

•reviewing HEP’s annual and quarterly financial statements with management and the independent registered public accounting firm;

•discussing with management HEP’s significant financial risk exposures and the actions management has taken to monitor and control such exposures;

•reviewing and, if appropriate, approving transactions involving conflicts of interest, including related party transactions, consistent with the Code and Related Party Transaction Policy;

•reviewing the Related Party Transaction Policy on an annual basis;

•reviewing and discussing HEP’s internal controls over financial reporting with management and the independent registered public accounting firm;

•establishing procedures for the receipt, retention and treatment of complaints received by HEP regarding accounting, internal accounting controls or accounting matters, potential violations of applicable laws, rules and regulations or of our codes, policies and procedures;

•reviewing the type and extent of any non-audit work to be performed by the independent registered public accounting firm and its compatibility with their continued objectivity and independence, and to the extent consistent, pre-approving all non-audit services to be performed;

•reviewing and approving the Audit Committee Report to be included in the Annual Report on Form 10-K; and

•reviewing the adequacy of the Audit Committee charter on an annual basis.

Each current member of the Audit Committee has the ability to read and understand fundamental financial statements. The Board has determined that Mr. Baldwin meets the requirements of an “audit committee financial expert” as defined by the rules of the SEC.

Conflicts Committee

The functions of the Conflicts Committee include reviewing specific matters that the Board or the Conflicts Committee believes may involve conflicts of interest with HFC. The Conflicts Committee determines if the resolution of the conflict of interest is fair and reasonable to HEP. Any matters approved by the Conflicts Committee will be conclusively deemed to be fair and reasonable to us, approved by all of our partners, and not a breach by our general partner of any duties it may owe us or our unitholders. In addition, the Conflicts Committee reviews the adequacy of the Conflicts Committee charter on an annual basis.

Compensation Committee

The functions of the Compensation Committee pursuant to its charter include:

•reviewing and approving the goals and objectives of HLS and HEP relevant to the compensation of the officers of HLS for whom the Compensation Committee determines compensation;

•determining compensation for the officers of HLS for whom the Compensation Committee determines compensation;

- 116 -

•reviewing director compensation and making recommendations to the Board regarding the same;

•overseeing the preparation of the Compensation Discussion and Analysis to be included in the Annual Report and preparing the Compensation Committee Report to be included in the Annual Report;

•reviewing the Company’s executive compensation plans with respect to behavioral, operational and other risks;

•administering and making recommendations to the Board with respect to HEP’s equity plan and HLS’s annual incentive plan; and

•reviewing the adequacy of the Compensation Committee charter on an annual basis.

Since the Compensation Committee is not comprised of all independent directors, equity awards, including performance goals applicable to such awards, if applicable, are approved by the full Board.

In January 2018, the Compensation Committee engaged Meridian Compensation Partners, LLC (“Meridian”), as the compensation consultant, to provide advice relating to executive, non-management director compensation, including benchmarking of the compensation peer group for non-management director compensation, and employee long-term equity incentive awards. At the time the Compensation Committee selected Meridian as its independent compensation consultant, and during the first quarter of every year since engaging Meridian, the Compensation Committee has assessed the independence of Meridian pursuant to SEC rules and considered, among other things, whether Meridian provides any other services to HLS or us, the fees paid by us to Meridian as a percentage of Meridian’s total revenues, the policies of Meridian that are designed to prevent any conflict of interest between Meridian, the Compensation Committee, HLS and us, any personal or business relationship between Meridian and a member of the Compensation Committee or one of HLS’s executive officers and whether Meridian owned any of our common units. In addition to the foregoing, the Compensation Committee annually receives an independence letter from Meridian, as well as other documentation addressing the firm’s independence. Meridian reports exclusively to the Compensation Committee and does not provide any additional services to HLS or us. The Compensation Committee has discussed these considerations and has concluded that Meridian is independent and that neither we nor HLS have any conflicts of interest with Meridian.

Report of the Audit Committee for the Year Ended December 31, 2021

Management of Holly Logistic Services, L.L.C. is responsible for Holly Energy Partners, L.P.’s system of internal controls over financial reporting. The Audit Committee selected, and the Board approved the selection of, Ernst & Young LLP as Holly Energy Partners, L.P.’s independent registered public accounting firm to audit the books, records and accounts of Holly Energy Partners, L.P. for the year ended December 31, 2021. Ernst & Young LLP is responsible for performing an independent audit of Holly Energy Partners, L.P.’s consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (“PCAOB”) and to issue a report thereon. The Audit Committee also is responsible for selecting, engaging and overseeing the work of the independent registered public accounting firm, which reports directly to the Audit Committee, and evaluating its qualifications and performance. Among other things, to fulfill its responsibilities, the Audit Committee:

•reviewed and discussed Holly Energy Partners, L.P.’s quarterly unaudited consolidated financial statements and its audited annual consolidated financial statements for the year ended December 31, 2021 with management and Ernst & Young LLP, including a discussion of the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments and the clarity of disclosures in the financial statements, including those in management’s discussion and analysis thereof;

•discussed with Ernst & Young LLP the matters required to be discussed by the applicable requirements of the PCAOB, the SEC and the NYSE;

•discussed with Ernst & Young LLP matters relating to its independence and received the written disclosures and letter from Ernst & Young LLP required by applicable requirements of the PCAOB regarding the independent accountant’s communications with the Audit Committee concerning the firm’s independence;

•discussed with Holly Energy Partners, L.P.’s internal auditors and Ernst & Young LLP the overall scope and plans for their respective audits and met with the internal auditors and Ernst & Young LLP, with and without management

- 117 -

present, to discuss the results of their examinations, their evaluations of our internal controls and the overall quality of Holly Energy Partners, L.P.’s financial reporting; and

•considered whether Ernst & Young LLP’s provision of non-audit services to Holly Energy Partners, L.P. is compatible with the auditor’s independence.

The Audit Committee charter requires the Audit Committee to approve in advance all audit and non-audit services to be provided by our independent registered public accounting firm. All fees for audit, audit-related and tax services as well as all other fees presented under Item 14 “Principal Accountant Fees and Services” were approved by the Audit Committee in accordance with its charter.

Based on the foregoing review and discussions and such other matters the Audit Committee deemed relevant and appropriate, the Audit Committee recommended to the Board that the audited consolidated financial statements of Holly Energy Partners, L.P. for the year ended December 31, 2021 be included in Holly Energy Partners, L.P.’s Annual Report on Form 10-K for the year ended December 31, 2021 for filing with the SEC.

Members of the Audit Committee:

Larry R. Baldwin, Chairperson

James H. Lee

Eric L. Mattson

Director Compensation

The Compensation Committee annually evaluates the compensation program for members of the Board who are not officers or employees of HLS or HFC (“non-employee directors”). Directors who also serve as officers or employees of HLS or HFC do not receive additional compensation for serving on the Board. We reimburse directors for all reasonable expenses incurred in attending Board and Board committee meetings and director continuing education sessions upon submission of appropriate documentation. No meeting fees are paid for Board or Board committee meetings.

For 2021, non-employee directors were entitled to receive an annual cash retainer, payable in cash, in addition to an annual equity retainer in the form of an award of phantom units described in the table below.

Larry R. Baldwin has served as Presiding Director of HLS since February 2020 when Mr. Jennings, Chairperson of the Board of HLS, became an executive officer of HFC and HLS. As an executive officer of HFC and HLS, Mr. Jennings does not receive any compensation for his service on the Board.

In October 2021, the Board approved non-employee director compensation for 2022. The only change from 2021 was a $10,000 increase in the annual equity retainer from $105,000 to $115,000. The awards that were granted in October 2021 (for 2022 services) were in the form of phantom units.

	Compensation in 2021		Compensation in 2022
Annual cash retainer	$	100,000	$	100,000
Annual cash retainer for the Presiding Director	$	25,000	$	25,000
Annual equity retainer (1)	$	105,000	$	115,000
Annual cash retainer for the Chairperson of the Board (2)	$	75,000	$	75,000
Annual cash retainer for Chairperson of committees (2)	$	25,000	$	25,000

__________________

(1)	The annual award is comprised of a number of phantom units equal to the annual equity retainer divided by the closing price of a common unit on the date of grant, with the number of phantom units rounded up in the case of fractional shares.
(2)	As an executive officer of HFC and HLS, Mr. Jennings does not receive any compensation for serving as Chairperson of the Board or Chairperson of the Compensation Committee of HLS.

- 118 -

Annual Equity Awards

Non-employee directors receive an annual equity award grant under the Holly Energy Partners, L.P. Amended and Restated Long-Term Incentive Plan (the “Long-Term Incentive Plan”) in the form of phantom units, with the number of awards calculated as described above. Continued service on the Board through the vesting date, which is approximately one year following the date of grant, is required for the awards to vest. Vesting of all unvested units will accelerate upon a change in control of HFC, HLS, HEP or HEP Logistics. In addition, vesting of unvested units will accelerate on a pro-rata basis upon the director’s death, total and permanent disability or retirement. Directors are entitled to receive all distribution equivalents paid with respect to outstanding awards, and these distribution equivalents are paid at approximately the same time as distributions are paid on our common units. The distribution equivalents are not subject to forfeiture.

Non-Qualified Deferred Compensation

Non-employee directors are eligible to participate in the HollyFrontier Corporation Executive Nonqualified Deferred Compensation Plan, which is not tax-qualified under Section 401 of the Internal Revenue Code and allows participants to defer receipt of certain compensation (the “NQDC Plan”). The NQDC Plan allows non-employee directors the ability to defer up to 100% of their cash retainers for a calendar year. Participating directors have full discretion over how their contributions to the NQDC Plan are invested among the investment options. Earnings on amounts contributed to the NQDC Plan are calculated in the same manner and at the same rate as earnings on actual investments. Neither HLS nor HFC subsidizes a participant’s earnings under the NQDC Plan.

None of our non-employee directors participated in the NQDC Plan in 2021. For additional information on the NQDC Plan, see “Compensation Discussion and Analysis–Overview of 2021 Executive Compensation Components and Decisions–Retirement and Benefit Plans–Deferred Compensation Plan” and the narrative preceding the “Nonqualified Deferred Compensation Table.”

Unit Ownership and Retention Policy for Directors

Our directors, other than those who serve as officers of HLS, are subject to the HEP unit ownership and retention policy. Pursuant to the policy, each director is required to hold during service on the Board common units equal in value to at least three times the annual equity retainer paid to non-employee directors. Each subject director is required to meet the applicable requirements within five years of first being subject to the policy.

Directors are also required to continuously own sufficient units to meet the unit ownership and retention requirements once attained. Until directors meet the requirements, they will be required to hold 25% of the units received from any equity award. If a director attains compliance with the policy and subsequently falls below the requirement because of a decrease in the price of our common units, the director will be deemed in compliance provided that the director retains the units then held.

As of December 31, 2021, all of our then-current directors were in compliance with the unit ownership and retention policy.

Anti-Hedging and Anti-Pledging Policy

All of our directors are subject to our Insider Trading Policy, which, among other things, prohibits directors from entering into short sales or hedging or pledging our common units and HFC common stock. The anti-hedging policy contained in our Insider Trading Policy specifically prohibits directors and their designees from purchasing financial instruments or otherwise engaging in transactions that hedge or offset or are designed to hedge or offset any decrease in the market value of HEP or HFC securities (or derivatives thereof), including through, among other mechanisms, the purchase of financial instruments (such as prepaid variable forward contracts, equity swaps, collars, and exchange funds) or other transactions that are designed to hedge or offset any decrease in the market value of shares of our common stock, regardless of how the securities (or derivatives thereof) were acquired. Additionally, all employees, including our named executive officers, are prohibited from holding shares of our common stock in a margin account or otherwise pledging shares of our common stock as collateral for a loan.

Eric L. Mattson	$	125,000	$	115,019	$	240,019

__________________

(1)     Mr. Jennings is not included in this table because he received no additional compensation for his service on the Board during 2021, since he was an executive officer of HFC and HLS. The compensation paid by HFC to Mr. Jennings in 2021 will be shown in HFC’s 2022 Proxy Statement. A portion of the compensation paid to Mr. Jennings by HFC in 2021 is allocated to the services he performed for us in his capacity as an executive officer of HLS and is disclosed in the “Summary Compensation Table” below.

(2)    Reflects the aggregate grant date fair value of phantom units granted to non-employee directors, computed in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718 (“FASB ASC Topic 718”), determined without regard to forfeitures. See Note 9 to our consolidated financial statements for the fiscal year ended December 31, 2021, for a discussion of the assumptions used in determining the FASB ASC Topic 718 grant date fair value of these awards.

On October 27, 2021, Messrs. Baldwin, Lee and Mattson and Ms. LaFollette received an award of 6,076 phantom units that vests on December 1, 2022, subject to continued service on the Board. As of December 31, 2021, these are the only phantom units held by our current non-employee directors. For additional information regarding the annual phantom unit grants, please refer to the “Director Compensation” narrative above.

Item 11. Executive Compensation

Compensation Discussion and Analysis

This Compensation Discussion and Analysis provides information about our compensation objectives and policies for the HLS executive officers who are our “Named Executive Officers” for 2021 to the extent the Compensation Committee and the Board, or our Chief Executive Officer determines the compensation of these individuals and about the compensation for our other Named Executive Officers that is allocated to us pursuant to Compensation Committee action or SEC rules. In addition, the Compensation Discussion and Analysis is intended to place in perspective the information contained in the executive compensation tables that follow this discussion and provide a description of our policies relating to reimbursement to HFC and HLS for compensation expenses.

Overview

We are managed by HLS, the general partner of HEP Logistics, our general partner. HLS is a subsidiary of HFC. The employees providing services to us are either provided by HLS, which utilizes people employed by HFC to perform services for us, or seconded to us by subsidiaries of HFC, as we do not have any employees.

- 120 -

For 2021, our “Named Executive Officers” were:

Name	Position with HLS in 2021
Michael C. Jennings	Chief Executive Officer
John Harrison	Senior Vice President, Chief Financial Officer and Treasurer
Richard L. Voliva III	President
Mark T. Cunningham	Senior Vice President, Operations and Engineering
Vaishali S. Bhatia	Senior Vice President, General Counsel and Secretary

        

In October 2021, Mr. Cunningham announced his future retirement from all officer and employee positions, to be effective February 18, 2022. In preparation for his retirement, his responsibilities were transferred to four other individuals at HLS, effective January 1, 2022.

Certain of our Named Executive Officers are also officers of HFC or provide services to HFC. During 2021:

•Mr. Cunningham spent all of his professional time managing our business and affairs and did not provide any services to HFC.

•Messrs. Jennings, Voliva and Harrison and Ms. Bhatia, who we generally refer to as the “HFC Shared Officers,” also served as executive officers of HFC and devoted as much of their professional time as was necessary to oversee the management of our business and affairs. All compensation paid to such executive officers by HFC is paid and determined by HFC, without input from the Compensation Committee.

Compensation Committee Interlocks and Insider Participation

The members of the Compensation Committee of the Board are Messrs. Jennings and Lee and Ms. LaFollette. Mr. Jennings also serves as the Chief Executive Officer of HLS. None of the members who served on the Compensation Committee at any time during 2021 had any relationship requiring disclosure under Item 13 of this annual report on Form 10-K entitled “Certain Relationships and Related Transactions, and Director Independence.” No executive officer of HLS served as a member of the compensation committee of another entity that had an executive officer serving as a member of our Board or our Compensation Committee. No executive officer of HLS served as a member of the board of another entity that had an executive officer serving as a member of our Compensation Committee, except that Mr. Jennings also serves as the Chief Executive Officer of HFC.

Fees and Reimbursements for Compensation of Named Executive Officers

•Administrative Fee Covers HFC Shared Officers. Under the terms of the Omnibus Agreement we pay an annual administrative fee to HFC (currently $2.6 million) for the provision of general and administrative services for our benefit, which may be increased or decreased as permitted under the Omnibus Agreement. The administrative services covered by the Omnibus Agreement include, without limitation, the costs of corporate services provided to us by HFC such as accounting, tax, information technology, human resources, in-house legal support and office space, furnishings and equipment. None of the services covered by the administrative fee are assigned any particular value individually. Although the administrative fee covers the services provided to us by the Named Executive Officers who are HFC Shared Officers, no portion of the administrative fee is specifically allocated to services provided by those Named Executive Officers to us. Rather, the administrative fee generally covers services provided to us by HFC and, except as described below, there is no reimbursement by us for the specific costs of such services. Typically we reflect our allocated amounts into cash compensation columns of the Summary Compensation Table, namely within the Base Salary column. For the 2021 year, the portion of compensation for certain Named Executive Officers exceeded base salaries, so there was a portion of compensation allocations that were reported in the “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table reflecting amounts earned pursuant to the HFC annual incentive bonus plan. A discussion of the non-equity incentive compensation payable by HFC will be disclosed in HFC’s 2022 Proxy Statement. See Item 13, “Certain Relationships and Related Transactions, and Director Independence” of this Annual Report on Form 10-K for additional discussion of our relationships and transactions with HFC.

•Reimbursements for Compensation of Dedicated HLS Officers. Under the Omnibus Agreement, we also reimburse HFC for certain expenses incurred on our behalf, such as for salaries and employee benefits for certain personnel employed by HFC who perform services for us on behalf of HLS, including the dedicated HLS officers, as described in greater detail below. The partnership agreement provides that our general partner will determine the expenses that

- 121 -

are allocable to us. In 2021, we reimbursed HFC for 100% of the compensation expenses incurred by HFC for salary, bonus, retirement and other benefits provided to Mr. Cunningham. With respect to equity compensation paid by us to Mr. Cunningham, HLS purchases the units delivered pursuant to awards under our Long-Term Incentive Plan, and we reimburse HLS for the purchase price of the units.

Compensation Decisions for Dedicated HLS Officers

•Generally. The Compensation Committee, pursuant to its charter, determines cash and bonus compensation only for HLS’s Chief Executive Officer, President or Chief Financial Officer if such officers are solely dedicated to HLS and are not HFC Shared Officers. During 2021, HLS’s Chief Executive Officer, President and Chief Financial Officer were HFC Shared Officers, and as a result, the Compensation Committee did not set cash and bonus compensation for any executive officer. For 2021, the Compensation Committee made compensation recommendations, which were subsequently approved by the Board, for Mr. Cunningham only with respect to long-term equity incentive awards. All other compensation provided to Mr. Cunningham for 2021, other than with respect to pension and retirement benefits as described below, was determined by the Chief Executive Officer and President of HLS and is reported, in accordance with SEC rules, in the tables that follow.

•Pension and Retirement Benefits. The Compensation Committee does not review or approve pension or retirement benefits for any of the Named Executive Officers. Rather, all pension and retirement benefits provided to the executives are the same pension and retirement benefits that are provided to employees of HFC generally, and such benefits are sponsored and administered entirely by HFC without input from HLS or the Compensation Committee. The pension and retirement benefits provided to Mr. Cunningham in 2021 are described below and were charged to us monthly in accordance with the Omnibus Agreement.

Allocation of Compensation and Compensation Decisions for HFC Shared Officers

•Generally. HFC makes all decisions regarding the compensation paid to the HFC Shared Officers, which compensation is covered by the administrative fee under the Omnibus Agreement (and therefore not subject to reimbursement by us); however, in accordance with SEC rules, for purposes of these disclosures, a portion of the compensation paid by HFC to the HFC Shared Officers for 2021 is allocated to the services they performed for us during 2021. The allocation was made based on the assumption that each of Messrs. Jennings, Voliva and Harrison and Ms. Bhatia spent, in the aggregate, the following percentage of his or her professional time on our business and affairs in 2021:

Name	Percentage of Time
Michael C. Jennings	20%
John Harrison	25%
Richard L. Voliva III	30%
Vaishali S. Bhatia	25%

Because HFC made all decisions regarding the compensation paid to Messrs. Jennings, Voliva, Harrison and Ms. Bhatia for 2021, those decisions are not discussed in this Compensation Discussion and Analysis. The total compensation paid by HFC to Messrs. Jennings and Voliva and Ms. Bhatia in 2021 will be disclosed in HFC’s 2022 Proxy Statement. The compensation paid by HFC to Mr. Harrison is discussed and disclosed in the tables that follow.

Objectives of Compensation Program

Our compensation program is designed to attract and retain talented and productive executives who are motivated to protect and enhance our long-term value for the benefit of our unitholders. Our objective is to be competitive with our industry and encourage high levels of performance from our executives.

In supporting our objectives, in applicable years, the Compensation Committee considers the cash compensation to be received by the dedicated HLS officers when determining equity compensation for the dedicated HLS officers; however, the Compensation Committee has not adopted any formal policies for allocating compensation among salary, bonus and long-term equity compensation.

- 122 -

In the fourth quarter of 2020, the Compensation Committee, with the assistance of the Chief Executive Officer and President, reviewed the mix and level of cash and long-term equity incentive compensation for Mr. Cunningham with a goal of providing competitive compensation for 2021 to retain him, while at the same time providing him incentives to maximize long-term value for us and our unitholders.

Role of the Compensation Consultant and the Compensation Committee in the Compensation Setting Process

Since 2018, the Compensation Committee has retained Meridian, a consulting firm specializing in executive compensation, to advise the Compensation Committee on matters related to executive and non-employee director compensation, including benchmarking of the compensation peer group for non-employee director compensation, and long-term equity incentive awards. The Compensation Consultant provided the Compensation Committee with market data, updates on related trends and developments, advice on program design, and input on compensation decisions for executive officers and non-employee directors. As discussed above under “The Board, Its Committees and Director Compensation–Board Committees–Compensation Committee,” the Compensation Committee has concluded that we do not have any conflicts of interest with Meridian.

The Compensation Committee generally makes compensation decisions for a given fiscal year in the fourth quarter of the prior year. The Compensation Consultant does not have authority to determine the ultimate compensation paid to executive officers or non-employee directors, and the Compensation Committee is under no obligation to utilize the information provided by the Compensation Consultant when making compensation decisions. The Compensation Consultant provides external context and other input to the Compensation Committee prior to the Compensation Committee approving salaries and fees, awarding bonuses and equity compensation or establishing awards for the upcoming year. Meridian provided information and advice to the Compensation Committee in 2020 with respect to matters related to non-management director compensation, including benchmarking of the compensation peer group for non-employee director compensation, and employee long-term equity incentive awards for 2021. The Compensation Committee is aware that Meridian is also providing similar services to the compensation committee at HFC but our Compensation Committee manages its relationship with Meridian independently of the relationship that Meridian has with the HFC compensation committee. The aggregate amount of fees HLS paid to Meridian for the services it engaged Meridian to perform during the 2021 fiscal year was approximately $19,907. The aggregate amount of fees HFC paid to Meridian for the services it engaged Meridian to perform during the 2021 fiscal year was approximately $263,000.

The Compensation Committee, pursuant to its charter, determines cash and annual incentive compensation for only HLS’s Chief Executive Officer, President or Chief Financial Officer, if such officers are solely dedicated to HLS and are not HFC Shared Officers. For all HLS officers who are eligible to receive equity awards under HEP’s equity plans, the Compensation Committee will review and recommend to the Board for approval, long-term equity incentive compensation.

Review of Market Data

Market pay levels are one of many factors considered by the Compensation Committee in setting equity compensation for the Named Executive Officers. In 2020, the Compensation Committee reviewed comparison data provided by the Compensation Consultant with respect to annual incentive levels and long-term incentive levels as one point of reference in evaluating the reasonableness and competitiveness of the incentive compensation paid to our executive officers as compared to companies with which we compete for executive talent. In addition, the Compensation Committee reviewed such data to evaluate whether our incentive compensation reflects practices of comparable companies of generally similar size and scope of operations. The Compensation Consultant obtained market information primarily from SEC filings of publicly traded companies that the Compensation Consultant and the Compensation Committee consider appropriate peer group companies and, from time to time, from published compensation surveys (such as the Liquid Pipeline Roundtable Compensation Survey). The purpose of the peer group is to provide a frame of reference with respect to executive equity compensation at companies of generally comparable size and scope of operations, rather than to set specific benchmarks for the compensation provided to the Named Executive Officers. We select peer group companies that we believe provide relevant data points for our consideration.

The peer group used in determining 2021 equity compensation included the following companies, which are representative of the companies with which we compete for talent:

Antero Midstream Corporation	Enable Midstream Partners, LP
Black Stone Minerals, L.P.	EnLink Midstream Partners, LP
Callon Petroleum Company	Phillips 66 Partners LP
Centennial Resource Development, Inc.	Shell Midstream Partners, L.P.
Crestwood Equity Partners LP	Summit Midstream Partners, LP
Delek Logistics Partners, LP	TC Pipelines, LP

The peer group used for 2021 compensation was adjusted from the peer group used with respect to 2020 compensation due to consolidation and simplification across the midstream industry sector and recommendations from the Compensation Consultant.

For years in which we make the compensation decisions for our executive officers, our objective generally is to position pay at levels approximately in the middle range of market practice, taking into account median levels derived from our peer group analysis. Following advice from the Compensation Consultant, we consider our salary and non-salary compensation components relative to the median compensation levels generally within the peer group rather than to an exact percentile above or below the median. For these purposes, if compensation is generally within plus or minus 20% of the market median, it is considered to be in the middle range of the market. As noted, however, this market analysis is just one of many factors considered when making overall compensation decisions for our executives.

Role of Named Executive Officers in Determining Executive Compensation

In making executive equity compensation decisions for 2021 for Mr. Cunningham, the Compensation Committee reviewed the total compensation provided to him in the prior year, his overall performance and market data provided by the Compensation Consultant. The Compensation Committee also considered recommendations by the Chief Executive Officer and President and other factors in determining the appropriate final equity compensation amounts to recommend to the Board.

Various members of management facilitated the Compensation Committee’s consideration of equity compensation for Named Executive Officers by providing data for the Compensation Committee’s review. This data includes, but is not limited to, performance evaluations, performance-based compensation provided to the Named Executive Officers in previous years, tax-related considerations and accounting-related considerations. Given the day-to-day familiarity that management has with the work performed, the Compensation Committee values management’s recommendations, although no Named Executive Officer has authority to determine or comment on compensation decisions directly related to himself or herself. As described above, the Compensation Committee reviewed and made a recommendation to the Board as to the long-term equity compensation of Mr. Cunningham for 2021.

In the fourth quarter of 2020, the Chief Executive Officer and President reviewed information similar to that provided to the Compensation Committee for purposes of determining salary and bonus compensation for Mr. Cunningham for 2021. The Chief Executive Officer sets compensation for his direct reports who are solely dedicated to HLS and who do not serve as President of HLS, and the President sets compensation for his direct reports who are solely dedicated to HLS and who do not serve as Chief Financial Officer of HLS.

Overview of 2021 Executive Compensation Components and Decisions

The components of compensation received by Mr. Cunningham in 2021 are as follows:

•base salary;

•annual incentive cash bonus compensation;

•long-term equity incentive compensation;

•severance and change in control benefits;

•health and retirement benefits; and

•perquisites.

- 124 -

Each of these components is described in further detail in the narratives and/or tables that follow.

Base Salary

Base salary for Mr. Cunningham for 2021 was determined by the President of HLS in the fourth quarter of 2020. The President considered Mr. Cunningham’s position, level of responsibility and performance in 2020. The President also reviewed competitive market data relevant to his position. Following a review of the various factors listed above, Mr. Cunningham’s 2021 base salary was $342,505, which was effective January 1, 2021 and which represented a 2.7% increase from Mr. Cunningham’s 2020 base salary of $333,500.

Annual Incentive Cash Bonus Compensation

Target awards and performance metrics for the 2021 annual incentive plan for Mr. Cunningham were determined by the President of HLS in the fourth quarter of 2020.

The following table sets forth the minimum, target and maximum award opportunities (as a percentage of annual base salary) for Mr. Cunningham for 2021, and the portion of Mr. Cunningham’s target award opportunity that is allocated to each performance measure (as a percentage of his annual base salary). These target percentages were unchanged from the 2020 year.

	Award Opportunities			Allocation Among Performance Measures (as a percentage of annual base salary)
Name	Minimum	Target	Maximum	Financial Measures	Operational Measures	Strategic and Individual Measures
Mark T. Cunningham	22.5%	45.0%	90.0%	18%	18%	9%

The financial measures are weighted equally with the operational measures. Awards are capped to avoid encouraging an excessive short-term focus, potentially at the expense of long-term performance.

To facilitate timely determination of award payouts, the measurement period for each of the above metrics covers four consecutive quarters starting with the fourth quarter of the preceding year (2020) and ending with the third quarter of the following year (2021).

These awards were subject to our achievement of specified levels of performance with respect to financial, operational and strategic and individual performance measures. The following table sets forth the various components for each measure.

Performance Measure (percentage of the annual bonus awards)	Components (percentage of each performance measure)	How It’s Measured (percentage of each component)
Financial (40%)	EBITDA	Cumulative EBITDA performance of HEP vs. Cumulative Target for HEP
Operational (40%)	• Environmental, Health and Safety (40%)(1) • Reliability (40%) (2) • Operating Expense vs. Budget (20%) (3)	• Recordable Injury Rate • Lost Time Injuries • Vehicle Incidents • Employee Based Environmental Releases • Solomon Liquid Pipeline Availability
Strategic and Individual (20%)	Relevant individual metrics for each named executive officer	Mark T. Cunningham  • Safety and environmental  • Capital project management

- 125 -

(1)The EHS metric is divided into the following four equally weighted measures:

•Recordable Injury Rate, which is based on the number of employees out of 100 that have been involved in a recordable event.

•Lost Time Injury, which is based on the number of injuries causing an employee to miss work.

•Vehicle Incidents, which is based on the number of incidents generating greater than $5,000 of property damage per 1,000,000 miles driven by HEP employees.

•Employee Based Environmental Releases, which is based on loss of containment caused by an employee that is reportable to either a state or federal agency.

(2)The reliability metric is based on the weighted average Solomon Liquid Pipeline Availability.

(3)Operating Expense includes all direct and controllable cash operating costs, which includes Selling, General and Administrative (SG&A) costs. Budgeted costs exclude asset write-downs, impairments, inventory valuation charges, unbudgeted litigation and legal settlement costs, environmental charges resulting from events which occurred prior to the beginning of the performance period, variable energy and utility costs, and unbudgeted bonus expenses and costs related to unbudgeted new capital assets brought online and acquisitions made during the period. The metric is based on the actual cash operating expense of each segment versus the budgeted cash operating expense for each segment.

Financial Measures

The table below sets forth the threshold, target and maximum performance levels for each financial measure and the actual results for the financial measures in 2021:

Metric	Threshold (50%)	Target (100%)	Maximum (200%)	Actual for 2021	Percent of Target Bonus Achievement

Mark T. Cunningham	45%	21.6%	38.5%	11.3%	71.3%	158.4%

Long-Term Equity Incentive Compensation

The Long-Term Incentive Plan was adopted by the Board in August 2004 with the objective of:

•promoting our interests by providing equity incentive compensation awards to eligible individuals;

•enhancing our ability to attract and retain the services of individuals who are essential for our growth and profitability;

•encouraging those individuals to devote their best efforts to advancing our business; and

•aligning the interests of those individuals with the interests of our unitholders.

The Compensation Committee and the Board typically grant long-term equity incentive awards to dedicated HLS officers on an annual basis. Annual long-term equity incentive award grants are made in the fourth quarter of the year preceding the year to which the award relates, in order to align the timing of the long-term equity incentive award grants with the timing of the other compensation decisions made for the dedicated HLS officers. As a result, annual long-term equity incentive awards for the 2021 year were granted in October 2020 to the individuals who were dedicated HLS officers at that time. Pursuant to SEC rules, the long-term equity incentive awards granted in October 2020 for the 2021 year are disclosed as 2020 compensation in the Summary Compensation Table (with respect to those Named Executive Officers who received long-term equity incentive awards from us in October 2020) and are not included in the 2021 Grants of Plan-Based Awards table; however, because these awards relate to the 2021 year, they are described in greater detail below.

In determining the appropriate amount and type of long-term equity incentive awards to be granted each year, the Compensation Committee and the Board consider the executive’s position, scope of responsibility, base salary and available compensation information for executives in comparable positions in similar companies. Our goal is to reward the creation of value and strong performance with variable compensation dependent on that performance.

For the 2021 year, the Board awarded both phantom units and performance units to Mr. Cunningham. Due to SEC rules regarding the timing of disclosures, Mr. Cunningham’s awards with respect to the 2021 year are reflected in the Executive Compensation Tables below as awards granted in the 2020 year. It is generally our practice not to make long-term equity incentive award grants to the HFC Shared Officers. Any equity compensation awards granted by HFC for 2021 to any of the HFC Shared Officers will be disclosed in HFC’s 2022 Proxy Statement to the extent such individuals are “named executive officers” of HFC for the 2021 year.

Phantom Unit Awards

In October 2020, Mr. Cunningham was granted phantom units with respect to 2021 services. The number of phantom units awarded was initially recommended by the Compensation Committee, and approved by the Board. Mr. Cunningham’s award was in a dollar amount established according to his pay grade. The award is then converted to a number of units by dividing the targeted dollar amount by the closing price of our common units on the grant date of the award. The following table sets forth the number of phantom units awarded to Mr. Cunningham in October 2020 for the 2021 fiscal year:

Name	Number of Phantom Units
Mark T. Cunningham	13,635

Phantom unitholders have the right to receive distribution equivalents and other distributions paid with respect to such phantom units, and these distribution equivalents are paid at approximately the same time as distributions are paid on our common units. The distribution equivalents are not subject to forfeiture.

The phantom units granted to Mr. Cunningham in October 2020 vest in three equal annual installments according to the schedule below, subject to continued employment by the unitholder.

Phantom Unit Vesting Criteria
Vesting Date (1)	Cumulative Amount of Phantom Units Vested
Immediately following December 1, 2021	1/3
Immediately following December 1, 2022	2/3
Immediately following December 1, 2023	All

    (1) Vesting will occur on the first business day following the vesting date set forth above if the vesting date falls on a Saturday or a Sunday. The provisions affecting the vesting of these awards upon a change in control or certain terminations of employment are described in greater detail below in the section titled “Potential Payments upon Termination and Change in Control.”

In connection with Mr. Cunningham's retirement on February 18, 2022, 2,092 phantom units granted under his 2020 phantom unit award described above vested on a pro rata basis in an amount attributable to the portion of the period of service Mr. Cunningham completed during the applicable vesting period and the remainder of the unvested phantom unit award was forfeited.

Performance Unit Awards

A performance unit is a notational phantom unit that entitles the grantee to receive a common unit upon the attainment of pre-established performance targets over a specified performance period, which may include the achievement of specified financial objectives determined by the Compensation Committee and the Board, and satisfaction of certain continued service conditions.

In October 2020, Mr. Cunningham was granted performance units with a performance period that began on January 1, 2021 and ends on December 31, 2023. An executive officer generally must remain employed through the end of the performance period to be eligible to earn any of the performance units. The provisions affecting the vesting of these awards upon a change in control or certain terminations of employment are described below in the section titled “Potential Payments upon Termination and Change in Control.”

With respect to the performance unit awards for the 2021 year, Mr. Cunningham was granted a target number of performance units. The target number was initially recommended by the Compensation Committee, and approved by the Board, in dollar amounts established according to the pay grade of the executive officer. The target award is then converted to a number of units by dividing the targeted dollar amount by the closing price of our common units on the grant date of the award. The

- 128 -

following table sets forth the target number of performance units granted to Mr. Cunningham in October 2020 for the 2021 year:

Name	Target Number of Performance Units
Mark T. Cunningham	13,635

The Board determined that performance metrics for the October 2020 grants would consist of (a) actual EBITDA compared to target EBITDA and (b) total unitholder return during the performance period as measured against that of the following incentive peer group:

Archrock Partners, L.P.	PBF Logistics LP
Crestwood Equity Partners LP	Phillips 66 Partners LP
Delek Logistics Partners, LP	Shell Midstream Partners, L.P.
Enable Midstream Partners, LP	Summit Midstream Partners, LP
EnLink Midstream Partners, LP	TC Pipelines, LP
MPLX LP

For the performance unit awards granted in October 2020 for the 2021 fiscal year:

•“EBITDA,” which determines 50% of the units earned at the end of the performance period, is defined as our earnings before interest, taxes, depreciation and amortization for each calendar year during the performance period. The Board believes EBITDA is an appropriate metric because it measures HEP’s profitability before the effects of items such as financings, capital expenditures and taxes.

•“total unitholder return,” which determines 50% of the units earned at the end of the performance period, is defined as (a) the appreciation in our unit price during the performance period (in dollars) plus cumulative distributions paid during the performance period plus any additional value or compensation received by unitholders such as units received from spinoffs, divided by (b) the closing price of our common units on the first business day of the performance period. The Compensation Committee believes total unitholder return is an appropriate metric because it (i) aligns the interests of management with the interests of unitholders and (ii) provides a useful means of comparing our overall performance relative to the overall performance of our incentive peer group.

The actual number of performance units earned at the end of the performance period will be equal to (a) the target number of performance units granted multiplied by (b) our average performance unit payout with respect to the performance metrics. The average performance unit payout is determined by adding our performance unit payout percentage with respect to each performance metric and dividing the sum by two.

For the EBITDA metric, actual aggregate EBITDA achieved during the performance period is compared to the aggregate Target EBITDA during the performance period and payout is determined in accordance with the following table:

EBITDA Achievement Relative to Target EBITDA	EBITDA Performance Percentage
Target EBITDA plus 2.5%	Maximum (200% of Target)
< Target EBITDA plus 2.5% but > Target EBITDA	Interpolate between 100% and 200%
Target EBITDA	Target (100%)
<Target EBITDA but > Target EBITDA minus 5%	Interpolate between 50% and 100%
Target EBITDA minus 5%	50% of Target (Minimum)
< Target EBITDA minus 5%	Zero

“Target EBITDA” is defined as the sum of the EBITDA targets established by the Compensation Committee for each calendar year during the performance period. Target EBITDA is communicated to the performance unit holder within the first quarter of each calendar year within the performance period.

- 129 -

For the total unitholder return metric, a percentile ranking of our total unitholder return versus the total unitholder return of each entity in our incentive peer group will be calculated at the end of the performance period and payout is determined in accordance with the following table:

Ranking of the Partnership within Peer Group	Total Unitholder Return Performance Percentage
>90th percentile	Maximum (200% of Target)
<90th percentile but > 50th percentile	Interpolate between 100% and 200%
50th percentile	Target (100%)
<50th percentile but > 25th percentile	Interpolate between 25% and 100%
25th percentile	25% of Target (Minimum)
<25th percentile	Zero

Earned performance unit awards will be paid in the form of fully vested common units. Prior to vesting, distributions are paid on each outstanding performance unit, based on the target number of performance units subject to the award, at the same rate as distributions paid on our common units. The distributions are not subject to forfeiture.

In connection with Mr. Cunningham’s retirement on February 18, 2022, 10,889 performance units granted under his 2020 performance unit award described above vested on a pro rata basis in an amount attributable to the portion of the period of service Mr. Cunningham completed during the applicable vesting period multiplied by the target number of performance units awarded and the remainder of the unvested 2020 performance unit award was forfeited.

Acquisition of Common Units for Long-Term Incentive Plan Awards

Common units delivered in connection with long-term equity incentive awards may be common units acquired by HLS on the open market, common units already owned by HLS, common units acquired by HLS directly from us or any other person or any combination of the foregoing. We currently do not hold treasury units. HLS is entitled to reimbursement by us for the cost of acquiring the common units utilized for the grant or settlement of long-term equity incentive awards.

Retirement and Other Benefits

Our Named Executive Officers participate in certain retirement plans sponsored and maintained by HFC. The cost of retirement benefits for dedicated HLS officers is charged monthly to us in accordance with the terms of the Omnibus Agreement. The terms of these benefit arrangements are described below.

Defined Contribution Plan

For 2021, Mr. Cunningham was eligible to participate in the HollyFrontier Corporation 401(k) Retirement Savings Plan, a tax qualified defined contribution plan (the “401(k) Plan”). Employees who are not eligible to participate in the NQDC Plan may contribute amounts between 0% and 75% of their eligible compensation to the 401(k) Plan, while employees who participate in the NQDC Plan may contribute amounts between 0% and 50% of their eligible compensation to the 401(k) Plan. Employee contributions that were made on a tax-deferred basis were generally limited to $19,500 for 2021, with employees 50 years of age or over able to make additional tax-deferred contributions of $6,500.

For 2021, all employees received an employer retirement contribution to the 401(k) Plan of 3% to 8% of the participating employee’s eligible compensation under the 401(k) Plan, subject to applicable Internal Revenue Code limitations, based on years of service, as follows:

Years of Service	Retirement Contribution (as percentage of eligible compensation)
Less than 5 years	3%
5 to 10 years	4%
10 to 15 years	5.25%
15 to 20 years	6.5%
20 years and over	8%

- 130 -

In addition to the retirement contribution, in 2021, employees received employer matching contributions to the 401(k) Plan equal to 100% of the first 6% of the employee’s eligible compensation contributed to the 401(k) plan up to compensation limits. Matching contributions vest immediately, and retirement contributions are subject to a three-year cliff-vesting period.

The 401(k) Plan benefits for Mr. Cunningham were charged to us in 2021 pursuant to the Omnibus Agreement.

Deferred Compensation Plan

In 2021, Mr. Cunningham was eligible to participate in the NQDC Plan. The NQDC Plan provides certain management and other highly compensated employees an opportunity to defer compensation in excess of qualified retirement plan limitations on a pre-tax basis and accumulate tax-deferred earnings to achieve their financial goals.

Participants in the NQDC Plan can contribute between 1% and 50% of their eligible earnings, which includes base salary and bonuses, to the NQDC Plan. Participants in the NQDC Plan may also receive certain employer-provided contributions, matching restoration contributions, retirement restoration contributions, and nonqualified nonelective contributions. Matching restoration contributions and retirement restoration contributions represent contribution amounts that could not be made under the 401(k) Plan due to Internal Revenue Code limitations on tax-qualified plans. Participants in the NQDC Plan are entitled to make independent deferral elections to the NQDC Plan and the 401(k) Plan, regardless of whether the individual has met the contribution limitations under the 401(k) Plan. See the narrative preceding the “Nonqualified Deferred Compensation Table” for additional information regarding these contributions and the other terms and conditions of the NQDC Plan.

The NQDC Plan benefits for Mr. Cunningham were charged to us in 2021 pursuant to the Omnibus Agreement.

Other Benefits and Perquisites

Our Named Executive Officers are eligible to participate in the same health and welfare benefit plans, including medical, dental, life insurance, and disability programs sponsored and maintained by HFC, that are generally made available to all full-time employees of HFC. Health and welfare benefits for Mr. Cunningham were charged to us in 2021 pursuant to the Omnibus Agreement.

It is the Compensation Committee’s policy to provide only limited perquisites to our Named Executive Officers. We provided a reserved parking space for Mr. Cunningham in 2021. In addition, we may also reimburse our executive officers for limited entertainment expenses that we deem to serve a business purpose and provide personal benefits to our executive officers in limited circumstances associated with executive team-building and strategy planning events.

Change in Control Agreements

Neither we nor HLS has entered into any employment agreements with any of the Named Executive Officers. On February 14, 2011, the Board adopted the Holly Energy Partners, L.P. Change in Control Policy (the “Change in Control Policy”) and the related form of Change in Control Agreement for certain officers of HLS (each, a “Change in Control Agreement”). The Change in Control Agreements contain “double-trigger” payment provisions that require not only a change in control of HFC, HLS or HEP, but also a qualifying termination of the executive’s employment within a specified period of time following the change in control in order for an officer to be entitled to benefits. We believe the Change in Control Agreements provide for management continuity in the event of a change in control and provide competitive benefits for the recruitment and retention of executives.

We entered into a Change in Control Agreement with Mr. Voliva, effective as of April 28, 2014, and Mr. Cunningham, effective as of February 14, 2011, in accordance with the Change in Control Policy. The Change in Control Agreement with Mr. Voliva was terminated effective October 31, 2016 when Mr. Voliva entered into a Change in Control Agreement with HFC. The Change in Control Agreement with Mr. Cunningham was terminated effective February 18, 2022 when Mr. Cunningham retired, however, pursuant to SEC disclosure rules, the material terms of that agreement as in effect on December 31, 2021 are still required to be described herein. See the section below titled “Potential Payments upon Termination or Change in Control” for additional details.

HFC has entered into Change in Control Agreements with Messrs. Jennings, Voliva and Harrison and Ms. Bhatia, which were in effect during 2021 and the costs of which are fully borne by HFC (the “HFC Change in Control Agreements”). Payments and benefits under the HFC Change in Control Agreements are triggered only upon a change in control of HFC. The material terms,

- 131 -

and the qualification, of the potential amounts payable under the HFC Change in Control Agreements with Messrs. Jennings and Voliva and Ms. Bhatia will be described in HFC’s 2022 Proxy Statement.

Unit Ownership and Retention Policy for Executives

The Board, the Compensation Committee and our executive officers recognize that ownership of our common units is an effective means by which to align the interests of our officers with those of our unitholders. The dedicated HLS officers are subject to the HEP unit ownership and retention policy. The unit retention requirement for Mr. Cunningham prior to his retirement was as follows:

Executive Officer	Value of Units
Mark T. Cunningham	1x Base Salary

Each covered officer is required to meet the applicable requirements within five years of first being subject to the policy. Officers are required to continuously own sufficient units to meet the unit ownership and retention requirements once attained. Until the officers attain compliance with the unit ownership and retention policy, the officers will be required to hold 25% of the units received from any equity award, net of any units used to pay the exercise price or tax withholdings. If an officer attains compliance with the unit ownership and retention policy and subsequently falls below the requirement because of a decrease in the price of our common units, the officer will be deemed in compliance provided that the officer retains the units then held.

As of December 31, 2021, Mr. Cunningham was in compliance with the unit ownership and retention policy.

Anti-Hedging and Anti-Pledging Policy

All of our employees, including our named executive officers, are subject to our Insider Trading Policy, which, among other things, prohibits employees from entering into short sales or hedging or pledging shares of our common units and HFC common stock. The anti-hedging policy contained in our Insider Trading Policy specifically prohibits employees, including our named executive officers, and their designees from purchasing financial instruments or otherwise engaging in transactions that hedge or offset or are designed to hedge or offset any decrease in the market value of HEP or HFC securities (or derivatives thereof), including through, among other mechanisms, the purchase of financial instruments (such as prepaid variable forward contracts, equity swaps, collars, and exchange funds) or other transactions that are designed to hedge or offset any decrease in the market value of shares of our common stock, regardless of how the securities (or derivatives thereof) were acquired. Additionally, all employees, including our named executive officers, are prohibited from holding shares of our common stock in a margin account or otherwise pledging shares of our common stock as collateral for a loan.

Tax and Accounting Implications

We account for equity compensation expenses under the rules of FASB ASC Topic 718, which requires us to estimate and record an expense for each award of equity compensation over the vesting period of the award. Accounting rules also require us to record cash compensation as an expense at the time the obligation is accrued. The Compensation Committee has taken into account the tax implications to us in its decision to grant long-term equity incentive compensation awards in the form of phantom units and performance units as opposed to options or unit appreciation rights.

Recoupment of Compensation

In October 2021, the Board revised its formal clawback policy originally adopted by the Board in 2018 (the “Clawback Policy”) to expand the applicability of the policy to former employees who are determined to have engaged in conduct in violation of the policy during their employment and to add a misconduct prong permitting the clawback of compensation for employees and former employees who are determined to have engaged in Misconduct (as defined below). The Clawback Policy provides that upon the occurrence of a material restatement of our financial statements (other than due to a change in accounting policy or applicable law) or upon certain acts of Misconduct, the Board may recover bonus and other incentive and equity based compensation (the “Incentive Compensation”) awarded to Board appointed officers of HLS and our subsidiaries. The Clawback Policy applies to both current and former employees who are Board appointed officers of HLS and our subsidiaries; provided, however, that the Clawback Policy only applies to Incentive Compensation awarded on or after November 1, 2021 for Board appointed officers who are former employees.

- 132 -

In the case of a material restatement of our financial statements (other than due to a change in accounting policy or applicable law), the Board may recover Incentive Compensation that was paid or awarded during the 24-month period preceding the restatement from such officers. In the event of such material restatement, if the Incentive Compensation would have been lower had it been calculated based on such restated results, the Compensation Committee may (as determined in its sole discretion and to the extent permitted by governing law and as appropriate under the circumstances) seek to recover for our benefit all or a portion of such Incentive Compensation awarded to any covered employee. In determining whether to seek recovery, the Compensation Committee may take into account any considerations as it deems appropriate, including whether the error was caused by intentional misconduct or fraud. The amount of any recovery and the source of such recovery (whether from unvested equity compensation or future compensation payable to the covered employee) will be determined in the sole discretion of the Compensation Committee.

In any instance in which a current Board appointed officer of HLS or our subsidiaries or a former Board appointed officer employed by HLS or our subsidiaries at any point during the twelve-month period preceding the date the Compensation Committee is notified of an event of Misconduct, which is defined to include any of the following acts or events (each an act of “Misconduct”):

•an act or acts of dishonesty constituting a felony or serious misdemeanor and resulting or intended to result directly in gain or personal enrichment at the expense of HLS, HEP or any of its subsidiaries;

•gross or willful and wanton negligence in the performance of such officer’s material and substantial duties of employment with HLS, HEP and its subsidiaries; or

•conviction of a felony involving moral turpitude;

the Compensation Committee may (as determined in its sole discretion and to the extent permitted by governing law and as appropriate under the circumstances) cause HLS to (a) seek recovery of Incentive Compensation that such officer was awarded or vested within the prior 24-month period or at any time during or following the Misconduct and/or (b) cancel such officer’s unvested, unearned or unsettled Incentive Compensation without consideration; provided, however, that recoupment of Incentive Compensation from former employees only applies to Incentive Compensation awarded on or after November 1, 2021.

Additionally, equity awards granted to Named Executive Officers are subject to the terms of the Long-Term Incentive Plan, which states that such awards may be cancelled, repurchased and/or recouped to the extent required by applicable law or any clawback policy that we adopt. In addition, the award agreements for our outstanding long-term incentive compensation awards state that the award and amounts paid or realized with respect to the award may be subject to reduction, cancellation, forfeiture or recoupment to the extent required by applicable law or any clawback policy that we adopt.

2022 Compensation Decisions

Long-Term Equity Incentive Compensation

On October 27, 2021, Mr. Cunningham notified the Board that he was retiring from all officer positions and as an employee of HLS and its subsidiaries effective February 18, 2022. Due to Mr. Cunningham’s retirement, no long-term equity incentive awards were granted to Mr. Cunningham in 2021 for the 2022 year. The Board did not grant any long-term equity incentive awards to any of the other Named Executive Officers in 2021 for the 2022 year.

(1)    Represents the aggregate grant date fair value of awards of equity awards made in the year indicated computed in accordance with FASB ASC Topic 718, determined without regard to forfeitures, and does not reflect the actual value that may be recognized by the executive. See Note 9 to our consolidated financial statements for the fiscal year ended December 31, 2021 for a discussion of the assumptions used in determining the FASB ASC Topic 718 grant date fair value of these awards.

For Mr. Cunningham, awards for the 2020 fiscal year granted in November 2019 are reported in the “Unit Awards” column of the Summary Compensation Table for 2019 and awards for the 2021 fiscal year granted in October 2020 are reported in the “Unit Awards” column of the Summary Compensation Table for 2020, in each case, in accordance with SEC rules. Mr. Cunningham did not receive an award for the 2022 fiscal year due to his retirement in February 2022.

For Mr. Voliva, the award reflected in 2020 was a grant of phantom units in recognition of his contributions to the Company for the 2020 fiscal year, including his advancement of business development opportunities and his oversight of growth projects.

The terms of the equity awards granted in October 2021 are described under “Compensation Discussion and Analysis-2022 Compensation Decision-Long-Term Equity Incentive Compensation.” For additional information on outstanding equity awards, see below under “Outstanding Equity Awards at Fiscal Year End.”

(2)    Represents the annual incentive amount, if any, paid under our Annual Incentive Plan. The 2021 award amounts under our Annual Incentive Plan are described above in greater detail under “Compensation Discussion and Analysis–Overview of 2021 Executive Compensation Components and Decisions–Annual Incentive Cash Bonus Compensation.” See Note 5 to the Summary Compensation Table for a discussion of the amounts reported as “Non-Equity Incentive Plan Compensation” with respect to Messrs. Jennings and Voliva and Ms. Bhatia for 2021. Although these amounts are reported in the “Non-

- 134 -

Equity Incentive Plan Compensation” column, they represent incentive compensation determined by and earned pursuant to the HFC annual incentive bonus program.

(3)    For 2021, includes the compensation as described under “All Other Compensation” below.

(4)    During 2021, each of these officers split their professional time between HFC and us, and all compensation paid to the officer for 2021 was determined and paid by HFC. In accordance with SEC rules, for purposes of these disclosures, a portion of the total compensation paid by HFC to these officers for 2021 is allocated to the services the officer performed for us during 2021. The allocation was made based on the assumption that each officer spent, in the aggregate, approximately the following percentage of his professional time in 2021 on our business and affairs:

Name	Percentage of Time
Michael C. Jennings	20%
Richard L. Voliva III	30%
Vaishali S. Bhatia	25%

    As a result, only the designated percentage of the total amount of compensation each officer received from HFC for 2021 has been reported in this table, and the allocated amount has been solely attributed in the table above to the officer’s base salary and non-equity incentive plan compensation. This amount represents the aggregate dollar value of total compensation paid to the officer by HFC (including base salary, non-equity incentive plan compensation, equity awards and other compensation), calculated pursuant to SEC rules, multiplied by the percentage set forth next to his name above. The total compensation paid by HFC to Messrs. Jennings and Voliva and Ms. Bhatia (including the portion of their salary and non-equity incentive compensation reported in this table), and a discussion of how the total amount of the officer’s non-equity incentive plan compensation for 2021 was determined, will be disclosed in HFC’s 2022 Proxy Statement.

(5)    During 2021, Mr. Harrison split his professional time between HFC and us, and all compensation paid to him for 2021 was determined and paid by HFC. In accordance with SEC rules, for purposes of these disclosures, a portion of the total compensation paid by HFC to him for 2021 is allocated to the services he performed for us during 2021. The allocation was made based on the assumption that he spent, in the aggregate, approximately 25% of his professional time in 2021 on our business and affairs.

As a result, only the designated percentage of the total amount of compensation Mr. Harrison received from HFC for 2021 has been reported in this table, and the allocated amount has been solely attributed in the table above to his base salary. This amount represents the aggregate dollar value of total compensation paid to him by HFC (including base salary, non-equity incentive plan compensation, equity awards and other compensation), calculated pursuant to SEC rules, multiplied by 25%. The total compensation paid by HFC to Mr. Harrison in 2021 (including the portion of his salary reported in this table) is as follows: (i) salary of $298,646 for the entirety of 2021, (ii) a one-time discretionary bonus of $70,000 relating to a successful corporate acquisition consummated in 2021, (iii) stock awards of $266,722, which reflect the aggregate grant date fair value of awards of restricted stock units and performance share units granted by HFC to Mr. Harrison in November 2021 (3,927 restricted stock units and 3,927 performance share units (at target), based on a grant date closing price of $33.96 for HFC’s common stock), calculated in accordance with FASB ASC Topic 718, (iv) a cash incentive award pursuant to the Long-Term Incentive Plan of $133,335, which vests over a three-year period in increments of one-third starting on December 1, 2022, (v) $252,122 pursuant to HFC’s 2021 annual incentive cash compensation program, (vi) $36,250 in 401(k) plan matching contributions and retirement contributions in 2021, and (vii) $32,416 in NQDC Plan matching contributions and retirement contributions in 2021. For additional information regarding HFC’s compensation arrangements, please refer to HFC’s 2022 Proxy Statement.

______________

(1)The value of the perquisites provided by us to our Named Executive Officers in 2021 did not exceed $10,000 in the aggregate, and therefore, in accordance with SEC rules, are not included in the table above or described in this footnote.

Grants of Plan-Based Awards

The following table sets forth information about plan-based awards granted to our Named Executive Officers under our equity and non-equity incentive plans during 2021. In this table, awards are abbreviated as “AICP” for the annual incentive cash awards under our Annual Incentive Plan.

Annual long-term equity incentive awards are made once each year in the fourth quarter of the year preceding the year to which the award relates in order to align the timing of the long-term equity incentive award grants with the timing of the other compensation decisions made for our executive officers. However, none of our Named Executive Officers received equity plan-based awards from us during 2021 for the 2022 fiscal year.

	Type	Grant  Date	Estimated Possible Payouts Under Non-Equity Incentive Plan Awards (1)			Estimated Future Payouts Under Equity Incentive Plan Awards			All Other Equity Awards	Grant Date Fair Value
Name			Threshold	Target	Maximum	Threshold	Target	Maximum
Michael C. Jennings	—	—	—	—	—	—	—	—	—	—
John Harrison	—	—	—	—	—	—	—	—	—	—
Richard L. Voliva	—	—	—	—	—	—	—	—	—	—
Mark T. Cunningham	AICP		$77,353	$154,706	$309,412
Vaishali S. Bhatia	—	—	—	—	—	—	—	—	—	—

(1)    Represents the potential payouts for awards granted under our annual incentive cash compensation program, which were subject to achieving certain performance targets with respect to financial measures, operational measures and strategic and individual measures. Amounts reported (a) in the “Threshold” column reflect 50% of the named executive officer’s target award opportunity under the annual incentive cash compensation program, which, in accordance with SEC rules, is the minimum amount payable for a certain level of performance under the award, (b) in the “Target” column reflect 100% of the named executive officer’s target award opportunity under the annual incentive cash compensation program, which is the target amount payable under the award, and (c) in the “Maximum” column reflect 200% of the named executive officer’s target award opportunity under the annual incentive cash compensation program, which is the maximum amount payable under the award. If less than minimum levels of performance, as described in the “Threshold” column, are attained with respect to the financial measures, operational measures and strategic and individual measures under the annual incentive cash compensation program, then 0% of the named executive officer’s target award opportunity will be earned. The performance targets and target awards are described under “Compensation Discussion and Analysis–Overview of 2021 Executive Compensation Components and Decisions–Annual Incentive Cash Bonus Compensation.” Although these awards were granted in the fourth quarter of 2020, they represent the 2021 Annual Incentive Plan awards and any payouts with respect to these awards are reported in the “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table for 2021. Amounts paid to Messrs. Jennings, Harrison and Voliva and Ms. Bhatia for 2021 were earned and paid pursuant to the HFC annual incentive bonus program and are not included in this Grants of Plan-Based Awards table. A full discussion and reporting of the amounts paid to Messrs. Jennings and Voliva and Ms. Bhatia will be disclosed in HFC’s 2021 Proxy Statement. The amount paid to Mr. Harrison is reported in Note 5 to the Summary Compensation Table above.

Outstanding Equity Awards at Fiscal Year End

The following table sets forth information regarding outstanding phantom units and performance units held by each Named Executive Officer as of December 31, 2021, including awards that were granted prior to 2021. The value of these awards was calculated based on a price of $16.49 per unit, the closing price of our common units on December 31, 2021. Messrs. Jennings and Harrison and Ms. Bhatia do not hold any outstanding equity awards under our Long-Term Incentive Plan, and the table below does not reflect any outstanding HFC equity awards held by any of our Named Executive Officers. Mr. Cunningham received accelerated vesting of certain awards shown in the table below in connection with his February 2022 retirement, described in more detail within the section below titled “Potential Payments Upon Termination or Change in Control.”

Under SEC rules, the number and value of performance units reported is based on the number of units payable at the end of the performance period assuming the target level of performance is achieved for the awards granted in 2019, and maximum with respect to the awards granted in 2020. In this table, awards are abbreviated as “PHUA” for phantom unit awards and “PUA” for performance unit awards. The provisions applicable to these awards upon certain terminations of employment or a change in control are described below in the section titled “Potential Payments upon Termination or Change in Control.”

Name	Award Type	Number of Units That Have Not Vested (1)	Market Value of Units That Have Not Vested		Equity Incentive Plan Awards: Number of Unearned Units or Other Rights That Have Not Vested (2)	Equity Incentive Plan Awards: Market or Payout Value of Unearned Units or Other Rights That Have Not Vested
Michael C. Jennings	—	—	—		—	—
John Harrison	—	—	—		—	—
Richard L. Voliva III	PHUA	36,354	$	599,477	—	—
Mark T. Cunningham	PHUA	11,216	$	184,952
	PUA				33,648	$	554,856
Vaishali S. Bhatia	—	—	—		—	—

(1)    Includes the following phantom unit awards granted by us:

•in October 2019 to Mr. Cunningham (2,126), which will vest on December 1, 2022; and

•in October 2020 to Mr. Voliva (36,354) and to Mr. Cunningham (9,090), half of which will vest on December 1, 2022 and the remaining half vests on December 1, 2023.

(2)    Includes the following performance unit awards granted by us (the amounts included in the parentheticals reflect the target number of performance units subject to each award):

•in October 2019 to Mr. Cunningham (6,378 at target), with a performance period that ends on September 30, 2022 and a service period that ends on December 1, 2022 (or the first business day thereafter if such date is a Saturday or a Sunday); and

•in October 2020 to Mr. Cunningham (13,635 at target, 27,270 at maximum), with a performance period that ends on September 30, 2023 and a service period that ends on December 1, 2023 (or the first business day thereafter if such date is a Saturday or a Sunday).

Option Exercises and Units Vested

The following table provides information regarding the vesting in 2021 of phantom unit and/or performance unit awards held by the Named Executive Officers. Messrs. Jennings and Harrison and Ms. Bhatia do not currently hold any equity awards under our Long-Term Incentive Plan, and they did not have any equity awards under our Long-Term Incentive Plan that vested during 2021. The table below does not reflect any information regarding the vesting in 2021 of any HFC equity awards held by any of our Named Executive Officers. To date, we have not granted any unit options.

The value realized from the vesting of restricted unit and phantom unit awards is generally equal to the closing price of our common units on the vesting date (or, if the vesting date is not a trading day, on the trading day immediately following the

- 137 -

vesting date, unless provided otherwise by the applicable award agreement) multiplied by the number of units acquired on vesting. The value is calculated before payment of any applicable withholding or other income taxes.

Named Executive Officer	Unit Awards
	Number of Units Acquired on Vesting	Value Realized on Vesting
Michael C. Jennings	—	—
John Harrison	—	—
Richard L. Voliva III	18,177	$298,466
Mark T. Cunningham (1)	11,804	$201,762
Vaishali S. Bhatia	—	—

(1)Includes the following number of common units (shown in column (b) below) that became payable to the executive officer on February 9, 2022 following the Board’s certification that the applicable standards for the target performance units granted to the executive officer in November 2018 (shown in column (a) below), the performance period for which ended December 31, 2021, had been met (based on a performance percentage of 65%), which performance units are treated, in accordance with SEC rules, as vesting during 2021:

Name	Performance Units Granted in November 2018 (a)	Number of Common Units (b)
Mark T. Cunningham	5,220	3,393

Nonqualified Deferred Compensation

In 2021, all of the Named Executive Officers participated in the NQDC Plan. The NQDC Plan is a nonqualified plan (i.e., not tax-qualified under Section 401 of the Code) that, in 2021, functioned as a pour-over plan, allowing key employees to defer tax on income in excess of Internal Revenue Code limits that apply under the 401(k) Plan. For 2021, the annual deferral contribution limit under the 401(k) Plan was $19,500, and the annual compensation limit was $290,000. Deferral elections made by eligible employees under the NQDC Plan apply to the total amount of eligible earnings the employees want to contribute across both the 401(k) Plan and the NQDC Plan. Prior to 2020, participants in the NQDC Plan were required to contribute the maximum contribution allowed under the 401(k) Plan before deferrals would be permitted in the NQDC Plan. On and after January 1, 2020, participants in the NQDC Plan are entitled to make independent deferral elections to the NQDC Plan and the 401(k) Plan prior to meeting the contribution limitations under the 401(k) Plan. Federal and state income taxes are generally not payable on income deferred under the NQDC Plan until funds are withdrawn.

Eligible participants may make salary deferral contributions between 1% and 50% of eligible earnings to the NQDC Plan. Eligible earnings include base pay, bonuses and overtime, but exclude extraordinary pay such as severance, accrued vacation, equity compensation and certain other items. In 2021, eligible participants were required to make catch-up contributions to the 401(k) Plan before any contributions will be deposited into the NQDC Plan. For 2021, the catch-up contribution limit was $6,500. Deferral elections are irrevocable for an entire plan year and must be made prior to December 31 of the year immediately preceding the plan year. Elections will carry over to the next plan year unless changed or otherwise revoked.

Participants in the NQDC Plan are eligible to receive a matching restoration contribution with respect to their elective deferrals made up to 6% of the participant’s eligible earnings for the plan year in excess of the limits under Section 401(k) of the Internal Revenue Code. These matching restoration contributions are fully vested at all times. In addition, participants are eligible for a retirement restoration contribution ranging from 3% to 8% of the participant’s eligible earnings for the plan year in excess of the limits under Section 401(k) of the Internal Revenue Code, based on years of service, as follows:

- 138 -

Years of Services	Retirement Contribution (as percentage of eligible compensation)
Less than 5 years	3%
5 to 10 years	4%
10 to 15 years	5.25%
15 to 20 years	6.5%
20 years and over	8%

Retirement restoration contributions are subject to a three-year cliff vesting period and will become fully vested in the event of the participant’s death or a change in control. Participants may also receive nonqualified nonelective contributions under the NQDC Plan, which contributions may be subject to a vesting schedule determined at the time the contributions are made.

Participating employees have full discretion over how their contributions to the NQDC Plan are invested among the offered investment options, and earnings on amounts contributed to the NQDC Plan are calculated in the same manner and at the same rate as earnings on actual investments. Neither HLS nor HFC subsidizes a participant’s earnings under the NQDC Plan. During 2021, the investment options offered under the NQDC Plan were the same as the investment options available to participants in the 401(k) Plan, except as follows:

•the 401(k) Plan offers the Mid Cap Value R1 Fund, Principal Stable Value Z Fund, Principal Self-Directed Brokerage Account, and the stock of HFC; and

•the NQDC Plan instead offers the American Century Mid-Cap Value I Fund, and Vanguard Federal Money Market Investor Fund.

The following table lists the investment options for the NQDC Plan in 2021 with the annual rate of return for each fund:

Investment Funds	Rate of Return
American Century Mid-Cap Value I Fund	23.30%

Benefits under the NQDC Plan may be distributed upon the earliest to occur of a separation from service (subject to a six month payment delay for certain specified employees under Section 409A of the Internal Revenue Code), the participant’s death, a change in control or a specified date selected by the participant in accordance with the terms of the NQDC Plan. Benefits are distributed from the NQDC Plan in the form of a lump sum payment or, in certain circumstances if elected by the participant, in the form of annual installments for up to a five-year period.

Nonqualified Deferred Compensation Table

The NQDC Plan benefits for Mr. Cunningham were charged to us in 2021 pursuant to the Omnibus Agreement. The following table provides information regarding all contributions to, and the year-end balance of, the NQDC Plan account for Mr. Cunningham. Even though Messrs. Jennings, Harrison, Voliva and Ms. Bhatia were also participants in the NQDC Plan in 2021, we have not provided any disclosure with respect to their NQDC Plan benefits since those benefits were entirely paid for by HFC during 2021. Additional information regarding the NQDC Plan, and participation in the NQDC Plan by Messrs. Jennings and Voliva and Ms. Bhatia will be provided in HFC’s 2022 Proxy Statement.

We reported executive and company contributions for Mr. Cunningham in the Summary Compensation Table in the following aggregate amounts:

Name	2021	Years Prior to 2021
Mark T. Cunningham	$88,739	$1,205,306

Potential Payments upon Termination or Change in Control

We had a Change in Control Agreement with Mr. Cunningham until his retirement on February 18, 2022 and we maintain the Long-Term Incentive Plan, which provides for severance compensation and/or accelerated vesting of equity compensation in the event of a termination of employment following a change in control or under other specified circumstances. These arrangements are summarized below.

Change in Control Agreements

HFC has entered into a Change in Control Agreement with each of Messrs. Jennings, Voliva and Harrison and Ms. Bhatia. Payments and benefits under the HFC Change in Control Agreements are triggered only upon certain termination events in connection with a change in control of HFC. A summary of the terms of the HFC Change in Control Agreements, and a quantification of potential benefits under the HFC Change in Control Agreement with Messrs. Jennings and Voliva and Ms. Bhatia, will be disclosed in HFC’s 2022 Proxy Statement.

We entered into a Change in Control Agreement with Mr. Cunningham, effective as of February 14, 2011, and his agreement terminated effective upon his retirement on February 18, 2022. For purposes of the disclosures below, we have continued to provide information on Mr. Cunningham’s potential benefits pursuant to that agreement as it was still in effect on December 31,

- 140 -

2021, although we have also provided a description of the actual amounts that he received in connection with his retirement in the 2022 year below. We entered into a Change in Control Agreement with Mr. Voliva, effective as of April 28, 2014, and such agreement terminated on October 31, 2016 when he entered into a Change in Control Agreement with HFC. Therefore, there are no Change in Control Agreements that we currently maintain with a Named Executive Officer as of the date of this filing.

Each Change in Control Agreement under our Change in Control Policy terminates on the day prior to the three-year anniversary of its effective date, and thereafter automatically renews for successive one-year terms (on each anniversary date thereafter) unless a cancellation notice is given by us 60 days prior to the automatic extension date. The Change in Control Agreements provide that if, in connection with or within two years after a “Change in Control” of HFC, HLS, HEP Logistics or HEP (1) the executive’s employment is terminated by HFC, HLS, HEP Logistics or HEP without “Cause,” by the employee for “Good Reason,” or as a condition of the occurrence of the transaction constituting the “Change in Control,” or (2) the executive does not remain employed by HFC, HLS, HEP Logistics or HEP or any of their respective affiliates or the executive is not offered employment with HFC, HLS, HEP, HEP Logistics or any of their affiliates on substantially the same terms in the aggregate as his previous employment within 30 days after the termination, then the executive will receive the following cash severance amounts paid by us:

•an amount equal to his accrued and unpaid salary, unreimbursed expenses and accrued vacation pay; and

•a lump sum amount equal to a designated multiplier times (i) the executive’s annual base salary as of the date of termination or the date immediately prior to the “Change in Control,” whichever is greater, and (ii) the executive’s annual bonus amount, calculated as the average annual bonus paid to him for the prior three years. The severance multiplier was 1.0 for Mr. Cunningham prior to his retirement.

The executive will also receive continued participation by the executive and his or her dependents in medical and dental benefits for the number of years equal to the executive’s designated severance multiplier, which, in the case of Mr. Cunningham, is one year.

For purposes of the Change in Control Agreements, a “Change in Control” occurs if:

•a person or group of persons (other than HFC or any of its wholly-owned subsidiaries; HLS, HEP, HEP Logistics or any of their subsidiaries) becomes the beneficial owner of more than 50% of the combined voting power of the then outstanding securities of HFC, HLS, HEP or HEP Logistics or more than 50% of the outstanding common stock or membership interests, as applicable of HFC or HLS;

•the individuals who as of the date of grant constituted a majority of HFC’s Board of Directors and individuals whose election by HFC’s Board of Directors, or nomination for election by the holders of the voting securities of HFC, was approved by a vote of at least two-thirds of the directors, cease for any reason to constitute a majority of HFC’s Board of Directors;

•the consummation of a merger, consolidation or recapitalization of HFC, HLS, HEP or HEP Logistics resulting in the holders of voting securities of HFC, HLS, HEP or HEP Logistics, as applicable, prior to the merger or consolidation owning less than 50% of the combined voting power of the voting securities of HFC, HLS, HEP or HEP Logistics, as applicable, or a recapitalization of HFC, HLS, HEP or HEP Logistics in which a person or group becomes the beneficial owner of securities of HFC, HLS, HEP or HEP Logistics, as applicable, representing more than 50% of the combined voting power of the then outstanding securities of HFC, HLS, HEP or HEP Logistics, as applicable;

•the holders of voting securities of HFC or HEP approve a plan of complete liquidation or dissolution of HFC or HEP, as applicable; or

•the holders of voting securities of HFC or HEP approve the sale or disposition of all or substantially all of the assets of HFC or HEP, as applicable, other than to an entity holding at least 60% of the combined voting power of the voting securities immediately prior to such sale or disposition.

For purposes of the Change in Control Agreements, “Cause” is defined as:

•the engagement in any act of willful gross negligence or willful misconduct on a matter that is not inconsequential; or

•conviction of a felony.

For purposes of the Change in Control Agreements, “Good Reason” is defined as, without the express written consent of the executive:

•a material reduction in the executive’s (or his supervisor’s) authority, duties or responsibilities;

- 141 -

•a material reduction in the executive’s base compensation; or

•the relocation of the executive to an office or location more than 50 miles from the location at which the executive normally performed the executive’s services, except for travel reasonably required in the performance of the executive’s responsibilities.

All payments and benefits due under the Change in Control Agreements will be conditioned on the execution and non-revocation by the executive of a release of claims for the benefit of HFC, HLS, HEP and HEP Logistics and their related entities and agents. The Change in Control Agreements also contain confidentiality provisions pursuant to which each executive agrees not to disclose or otherwise use the confidential information of HFC, HLS, HEP or HEP Logistics. Violation of the confidentiality provisions entitles HFC, HLS, HEP or HEP Logistics to complete relief, including injunctive relief. Further, in the event of a breach of the confidentiality covenants, the executive could be terminated for Cause (provided the breach constituted willful gross negligence or misconduct on the executive’s part that is not inconsequential). The agreements do not prohibit the waiver of a breach of these covenants.

If amounts payable to an executive under a Change in Control Agreement (together with any other amounts that are payable by HFC, HLS, HEP or HEP Logistics as a result of a change in ownership or control) exceed the amount allowed under Section 280G of the Internal Revenue Code for such executive by 10% or more, we will pay the executive an amount necessary to allow the executive to retain a net amount equal to the total present value of the payments on the date they are to be paid. Conversely, if the payments exceed the 280G limit for the executive by less than 10%, the payments will be reduced to the level at which no excise tax applies.

Long-Term Equity Incentive Awards

The outstanding long-term equity incentive awards granted under the Long-Term Incentive Plan to our Named Executive Officers vest upon a “Special Involuntary Termination,” which occurs when, within 60 days prior to or at any time after a “Change in Control”:

•the executive’s employment is terminated, other than for “Cause,” or

•the executive resigns within 90 days following an “Adverse Change.”

All outstanding performance units granted in 2019 will vest at 200% in the event of a Special Involuntary Termination and all outstanding performance units granted during 2020 or thereafter will vest at 100% (target) in the event of a Special Involuntary Termination.

In the event of an executive’s death, disability or retirement, phantom units and performance units vest as follows:

•Phantom Units: Upon death or disability, the executive will vest with respect to a pro rata number of units attributable to the period of service completed during the applicable vesting period and will forfeit any unvested units. Under the phantom units granted in or after November 2019, upon “Retirement,” the executive will vest with respect to a pro rata number of units attributable to the period of service completed during the applicable vesting period and will forfeit any unvested units.

•Performance Units: Pursuant to the terms of the performance unit award agreements for grants awarded in or after November 2019, upon “Retirement”, and in the case of the October 2020 performance unit awards, upon death or disability, the executive becomes vested in a number of performance units attributable to the period of service completed during the applicable vesting period multiplied by the target number of performance units awarded and will forfeit any unvested units. Pursuant to the terms of the October 2019 and October 2020 performance unit award agreements, upon death or disability, the executive will remain eligible to vest with respect to a pro-rata number of units attributable to the period of service completed during the applicable performance period (rounded up to include the month of termination) and will forfeit any unvested units. For the October 2019 and October 2020 performance unit award agreements, the Compensation Committee will determine the number of remaining performance units earned and the amount to be paid to the executive as soon as administratively possible after the end of the performance period based upon the performance actually attained for the entire performance period. For the October 2019 and October 2020 performance unit award agreements, the foregoing also applies if the executive separates from employment for any other reason other than a voluntary separation, Special Involuntary Termination or for “Cause.”

- 142 -

For purposes of the long-term equity incentive awards, a “Change in Control” occurs if:

•a person or group of persons (other than HFC or any of its wholly-owned subsidiaries or HLS, HEP, HEP Logistics or any of their subsidiaries) becomes the beneficial owner of more than 40% of the combined voting power of the then outstanding securities of HFC, HLS, HEP or HEP Logistics;

•the individuals who as of the date of grant constituted a majority of HFC’s Board of Directors cease for any reason to constitute a majority of HFC’s Board of Directors;

•the consummation of a merger, consolidation or recapitalization of HFC, HLS, HEP or HEP Logistics resulting in the holders of voting securities of HFC, HLS, HEP or HEP Logistics, as applicable, prior to the merger or consolidation owning less than 60% of the combined voting power of the voting securities of HFC, HLS, HEP or HEP Logistics, as applicable, or a recapitalization of HFC, HLS, HEP, or HEP Logistics in which a person or group becomes the beneficial owner of securities of HFC, HLS, HEP or HEP Logistics, as applicable, representing more than 40% of the combined voting power of the then outstanding securities of HFC, HLS, HEP or HEP Logistics, as applicable;

•the holders of voting securities of HFC, HLS, HEP or HEP Logistics approve a plan of complete liquidation or dissolution of HFC, HLS, HEP or HEP Logistics, as applicable; or

•the holders of voting securities of HFC, HLS, HEP or HEP Logistics approve the sale or disposition of all or substantially all of the assets of HFC, HLS, HEP or HEP Logistics, as applicable, other than to an entity holding at least 60% of the combined voting power of the voting securities immediately prior to such sale or disposition.

For purposes of the phantom unit awards and the performance units, “Retirement” is defined as a termination of employment other than for Cause on or after the date on which the executive: (i) has achieved ten years of continuous service and (ii) has attained age sixty.

For purposes of the performance unit awards, “Adverse Change” is defined as, without the consent of the executive:

•a change in the executive’s principal office of employment of more than 25 miles from the executive’s work address at the time of grant of the award;

•a material increase (without adequate consideration) or material reduction in the duties to be performed by the executive; or

•a material reduction in the executive’s base compensation (other than bonuses and other discretionary items of compensation) that does not apply generally to employees.

For purposes of the long-term equity incentive awards, “Cause” is defined as:

•an act of dishonesty constituting a felony or serious misdemeanor and resulting (or intended to result in) gain or personal enrichment to the executive at the expense of HLS;

•gross or willful and wanton negligence in the performance of the executive’s material and substantial duties; or

•conviction of a felony involving moral turpitude.

The long-term equity incentive awards granted in 2019 and 2020 were granted to our Named Executive Officers with certain restrictive covenants that generally mirror the release requirements and confidentiality restrictions found in our Change in Control Agreements described above. The awards were also granted with non-solicitation provisions that generally prevent the Named Executive Officers from soliciting any employee or service provider of us or our affiliates for one year following a termination of employment.

Quantification of Benefits

The following table summarizes the compensation and other benefits that would have been payable to the Named Executive Officers under the arrangements described above assuming their employment terminated under various scenarios, including in connection with a change in control, on December 31, 2021. For these purposes, our common unit price was assumed to be $16.49, which was the closing price per unit on December 31, 2021.

In reviewing the table, please note the following:

•For purposes of determining amounts under the “Cash Payments” column, accrued and unpaid salary and unreimbursed expenses were assumed to equal zero.

- 143 -

•Accrued vacation for a specific year is not allowed to be carried over to a subsequent year, so we assumed all accrued vacation for the 2021 year was taken prior to December 31, 2021. Because we accrue vacation in any given year for the following year, amounts reported as “Cash Payments” include vacation amounts for Mr. Cunningham of $39,521 accrued in 2021 for the 2022 year.

•For amounts payable to the Named Executive Officers with respect to performance units, either through a pro-rata settlement or based on actual performance, we assumed the performance units would settle at 100% at the time of the calculation. The number of units paid at the end of the performance period may vary from the amounts reflected in the following tables, based on our actual achievement compared to the performance targets.

•Mr. Cunningham was eligible for retirement as of December 31, 2021. Assuming that Mr. Cunningham had retired on December 31, 2021 instead of in the 2022 year, his retirement benefits would have consisted of accelerated vesting of phantom units valued at $14,353 and accelerated vesting of performance units valued at $159,416. We assumed that Mr. Cunningham’s performance units granted in 2020 and 2019 would vest according to the pro-rata formula within his award agreements.

•The amount shown for “Value of Welfare Benefits” represents amounts equal to the monthly premium payable pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), for medical and dental premiums, multiplied by 12 months for Mr. Cunningham.

•In calculating whether any tax reimbursements were owed to the Named Executive Officers, we used the following assumptions: (a) no amounts will be discounted as attributable to reasonable compensation, (b) all cash severance payments are contingent upon a change in control and (c) the presumption required under applicable regulations that the equity awards granted in 2021 were contingent upon a change in control could be rebutted. Based on these assumptions, none of the Named Executive Officers would receive any tax reimbursement or “gross-up” payments with respect to any amounts reported in the table below.

•No amounts potentially payable pursuant to the NQDC Plan are included in the table below since neither the form nor amount of any such benefits would be enhanced nor vesting or other provisions accelerated in connection with any of the triggering events disclosed below. Please refer to the section titled “Nonqualified Deferred Compensation” for additional information regarding these benefits.

Retirement Arrangements with Mark T. Cunningham

On October 27, 2021, Mr. Cunningham notified the Board of HLS that he was retiring from all officer positions and as an employee of HLS and its subsidiaries, effective February 18, 2022. Due to his expertise, history with HLS, involvement in current projects and the need to orderly transition his duties and knowledge to other individuals at HLS, starting on February 19, 2022, Mr. Cunningham will provide consulting services to HLS and its subsidiaries on a month-to-month basis for a period of twelve months. In connection with his consulting arrangement, Mr. Cunningham agreed to keep information about HLS and its subsidiaries obtained during his time as a consultant confidential. As consideration for his services, HLS will pay Mr. Cunningham a retainer of $50,000 per month to provide up to 40 hours of services per month to HLS and its subsidiaries as requested by senior management from time to time.

- 144 -

The outstanding equity awards that Mr. Cunningham held on February 18, 2022 received accelerated vesting. A total of 2,092 of his phantom units and 10,889 of his performance units were accelerated, for an aggregate value of $229,634 as of his retirement date. His vested phantom unit and performance unit awards will be settled six months following his retirement date, as Mr. Cunningham is subject to certain executive officer level deferral requirements imposed by Section 409A of the Code.

Compensation Practices as They Relate To Risk Management

Although a significant portion of the compensation provided to the Named Executive Officers is performance-based, we believe our compensation programs do not encourage excessive and unnecessary risk taking by executive officers (or other employees) because these programs are designed to encourage employees to remain focused on both our short- and long-term operational and financial goals.

While annual cash-based incentive bonus awards play an appropriate role in the executive compensation program, the Compensation Committee believes that payment determined based on an evaluation of our performance on a variety of measures, including comparing our performance over the last year to our past performance, mitigates excessive risk-taking that could produce unsustainable gains in one area of performance at the expense of our overall long-term interests. In addition, we set performance goals that we believe are reasonable in light of our past performance and market conditions.

For Named Executive Officers performing all of their services for us, an appropriate part of total compensation is fixed, while another portion is variable and linked to performance. A portion of the variable compensation we provide is comprised of long-term incentives. A portion of the long-term incentives we provide is in the form of phantom units subject to time-based vesting conditions, which retains value even in a depressed market, so executives are less likely to take unreasonable risks. With respect to our performance units, payouts result in some compensation at levels below full target achievement, in lieu of an “all or nothing” approach. Further, our unit ownership guidelines require certain of our executives to hold at least a specified level of units (in addition to unvested and unsettled equity-based awards), which aligns an appropriate portion of their personal wealth to our long-term performance and the interests of our unitholders.

Also, our Clawback Policy requires the return of annual and long-term incentive compensation for:

•the occurrence of a material financial restatement (other than due to a change in accounting policy or applicable law);

•certain acts of dishonesty constituting a felony or serious misdemeanor and resulting or intending to result directly in gain or personal enrichment at the expense of HLS, HEP or any of its subsidiaries;

•gross or willful and wanton negligence in the performance of material and substantial duties of employment with HLS, HEP and its subsidiaries; and

•felony convictions involving moral turpitude.

Based on the foregoing and our annual review of our compensation programs, we do not believe that our compensation policies and practices are reasonably likely to have a material adverse effect on us or our unitholders.

CEO Pay Ratio

The employees providing services to us are either provided by HLS, which utilizes people employed by HFC to perform services for us, or seconded to us by subsidiaries of HFC, as we do not have any employees for purposes of the pay ratio rules. Rather than providing a pay ratio disclosure that contemplates no employees, we have determined that the disclosure that would be most aligned with the spirit of the pay ratio rules and that would provide our unitholders with more meaningful information would be to provide a ratio using the median employee from the HFC employee population. As a result, we have used the same median employee that was identified by HFC following HFC’s examination of the 2021 taxable wages for all individuals who were employed by HFC in the U.S., Canada, and the Netherlands on December 15, 2021.

HFC identified the median employee by examining the 2021 taxable wages for all of its U.S., Canadian and Netherlands employees, including its CEO, who were employed by HFC on December 15, 2021. HFC included all U.S., Canadian and Netherlands employees, whether employed on a full-time, part-time, temporary or seasonal basis. As of December 15, 2021 HFC employed 4,176 such persons. As permitted by the SEC rules, HFC excluded its 50 employees located in Austria, China, Germany, and the U.K. since those employees comprise less than 5% of HFC’s 4,226 worldwide employees. HFC did not make any assumptions, adjustments or estimates with respect to the taxable wages other than deducting stock vesting from the taxable wages, and HFC did not annualize the wages for any employees that were not employed by HFC for all of 2021. HFC

- 145 -

believes the use of taxable wages is the most appropriate compensation measure since it allows for a consistent measurement for employees in different countries.

After identifying the median employee based on total taxable wages, HFC calculated annual 2021 compensation for the median employee using the methodology provided in the SEC rules. HFC’s median employee’s annual 2021 compensation was as follows:

Name	Year	Salary	Bonus	Stock Awards	Non-Equity Incentive Plan Compensation	All Other Compensation	Total
Median Employee	2021	$103,189	—	—	$20,312	$12,350	$135,851

Our 2021 ratio of chief executive officer total compensation to the HFC median employee’s total compensation is reasonably estimated to be 17:1.

Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Unitholder Matters

The following table sets forth as of February 15, 2022 the beneficial ownership of common units of HEP held by:

•each person known to us to be a beneficial owner of 5% or more of the common units;

Equity Compensation Plan Table

The following table summarizes information about our equity compensation plans as of December 31, 2021:

Plan Category (1)	Number of securities to be issued upon exercise of outstanding options, warrants and rights	Weighted average exercise price of outstanding options, warrants and rights	Number of securities remaining available for future issuance under equity compensation plans
Equity compensation plans approved by security holders (2)	356,701 (3)	—	753,425
Equity compensation plans not approved by security holders	—	—	—
Total	356,701	—	753,425

(1)All stock-based compensation plans are described in Note 9 to our consolidated financial statements for the fiscal year ended December 31, 2021.

(2)On April 25, 2012, at a Special Meeting of the Unitholders of the Partnership, the unitholders approved the Long-Term Incentive Plan, which, among other things, provided for an increase in the maximum number of common units reserved for delivery with respect to awards under the Long-Term Incentive Plan to 2,500,000 common units (as adjusted to reflect the two-for-one common unit split that occurred on January 16, 2013). All securities reported as available for future issuances are available from the additional common units approved by unitholders under the Long-Term Incentive Plan. At the time the Long-Term Incentive Plan was originally adopted in 2004, it was not required to be approved by HEP’s unitholders.

(3)Includes 153,438 units subject to performance units granted to key individuals under the Long-Term Incentive Plan assuming the maximum payout level. If the performance units are paid at the target payout level, 76,719 units would be issued upon the vesting of such performance units. Performance units granted in November 2018 with a performance period that ended on December 31, 2021 were not settled until certification by the Board in February 2022 that a performance percentage of 65% was attained for these performance units; however, such awards are not included in this column as outstanding since they are treated for purposes of the preceding executive compensation tables as vesting during 2021 in accordance with SEC rules.

For more information about our Long-Term Incentive Plan, refer to Item 11, “Executive Compensation - Overview of 2021 Executive Compensation Components and Decisions - Long-Term Incentive Equity Compensation.”

Item 13.Certain Relationships and Related Transactions, and Director Independence

Our general partner and its affiliates own 59,630,030 of our common units representing a 57% limited partner interest in us. In addition, the general partner owns the non-economic general partner interest in us. Transactions with our general partner are discussed later in this section.

DISTRIBUTIONS AND PAYMENTS TO THE GENERAL PARTNER AND ITS AFFILIATES

The following table summarizes the distributions and payments to be made by us to our general partner and its affiliates in connection with the ongoing operation and liquidation of HEP. These distributions and payments were determined by and among affiliated entities and, consequently, are not the result of arm’s-length negotiations.

- 148 -

Operational stage

Distributions of available cash to our general partner and its affiliates

We currently distribute all of our available cash to unitholders of record on the applicable record date within 45 days after the end of each quarter, pro rata.

Payments to our general partner and its affiliates

We pay HFC or its affiliates an administrative fee, currently $2.6 million per year, for the provision of various general and administrative services for our benefit. The administrative fee may increase if we make an acquisition that requires an increase in the level of general and administrative services that we receive from HFC or its affiliates. In addition, the general partner is entitled to reimbursement for all expenses it incurs on our behalf, including other general and administrative expenses. These reimbursable expenses include the salaries and the cost of employee benefits of employees of HFC who provide services to us on behalf of HLS. Finally, HLS is required to reimburse HFC for our benefit pursuant to the secondment arrangement for the wages, benefits, and other costs of HFC employees seconded to HLS to perform services at certain of our pipelines and tankage assets. Please read “Omnibus Agreement” and “Secondment Arrangement” below. Our general partner determines the amount of these expenses.

Liquidation stage

Liquidation Upon our liquidation, the partners, including our general partner, will be entitled to receive liquidating distributions according to their particular capital account balances.

OMNIBUS AGREEMENT

Our Omnibus Agreement with HFC and our general partner that addresses the following matters:

•our obligation to pay HFC an annual administrative fee, in the amount of $2.6 million for 2021, for the provision by HFC of certain general and administrative services;

•HFC’s and its affiliates’ agreement not to compete with us under certain circumstances and our right to notice of, and right of first offer to purchase, certain logistics assets constructed by HFC and acquired as part of an acquisition by HFC of refining assets;

•an indemnity by HFC for certain potential environmental liabilities;

•our obligation to indemnify HFC for environmental liabilities related to our assets existing on the date of our initial public offering to the extent HFC is not required to indemnify us; and

•HFC’s right of first refusal to purchase our assets that serve HFC’s refineries.

Payment of general and administrative services fee

Under the Omnibus Agreement, we pay HFC an annual administrative fee, in the amount of $2.6 million for 2021, for the provision of various general and administrative services for our benefit. This fee is subject to annual adjustment for changes in the Producer Price Index Commodities - Finished Goods, et al. Our general partner may agree to further increases in connection with expansions of our operations through the acquisition or construction of new assets or businesses.

The administrative fee includes expenses incurred by HFC and its affiliates to perform centralized corporate functions, such as legal, accounting, treasury, information technology and other corporate services, including the administration of employee benefit plans. The fee does not include salaries of pipeline and terminal personnel or other employees of HFC who perform services for us on behalf of HLS or the cost of their employee benefits, such as 401(k), pension, and health insurance benefits, which are separately charged to us by HFC. We also reimburse HFC and its affiliates for direct general and administrative expenses they incur on our behalf.

Noncompetition

HFC and its affiliates have agreed, for so long as HFC controls our general partner, not to engage in, whether by acquisition or otherwise, the business of operating crude oil pipelines or terminals, refined product pipelines or terminals, intermediate pipelines or terminals, truck racks or crude oil gathering systems in the continental United States. This restriction will not apply to:

•any business operated by HFC or any of its affiliates at the time of the closing of our initial public offering;

- 149 -

•any business conducted by HFC with the approval of our general partner;

•any business or asset that HFC or any of its affiliates acquires or constructs that has a fair market value or construction cost of less than $5 million; and

•any business or asset that HFC or any of its affiliates acquires or constructs that has a fair market value or construction cost of $5 million or more if we have been offered the opportunity to purchase the business or asset at fair market value, and we decline to do so.

The limitations on the ability of HFC and its affiliates to compete with us will terminate if HFC ceases to control our general partner.

Indemnification

Under the Omnibus Agreement, certain transportation agreements and purchase agreements with HFC, HFC has agreed to indemnify us, subject to certain limitations, for environmental noncompliance and remediation liabilities associated with certain assets transferred to us from HFC and occurring or existing prior to the date of such transfers. The Omnibus Agreement provides environmental indemnification with respect to certain transferred assets of up to $7.5 million through 2023 and $15 million through 2026. HFC's indemnification obligations under the Omnibus Agreement do not apply to assets we acquire from third parties, assets we construct or assets we relocate after they are transferred to us from HFC. For the Tulsa loading racks acquired from HFC in August 2009 and the Tulsa logistics and storage assets acquired from Sinclair in December 2009, HFC agreed to indemnify us for environmental liabilities arising from our pre-ownership operations of these assets. Additionally, HFC agreed to indemnify us for any liabilities arising from its operation of our loading racks located at HFC's Tulsa refinery west facility.

We have indemnified HFC and its affiliates against environmental liabilities related to events that occur on our assets after the date we acquired such asset.

Right of first refusal to purchase our assets

The Omnibus Agreement also contains the terms under which HFC has a right of first refusal to purchase our assets that serve its refineries. Before we enter into any contract to sell pipeline and terminal assets serving HFC’s refineries, we must give written notice of the terms of such proposed sale to HFC. The notice must set forth the name of the third-party purchaser, the assets to be sold, the purchase price, all details of the payment terms and all other terms and conditions of the offer. To the extent the third-party offer consists of consideration other than cash (or in addition to cash), the purchase price shall be deemed equal to the amount of any such cash plus the fair market value of such non-cash consideration, determined as set forth in the Omnibus Agreement. HFC will then have the sole and exclusive option for a period of thirty days following receipt of the notice, to purchase the subject assets on the terms specified in the notice.

SECONDMENT ARRANGEMENT

Under HLS’s secondment arrangement with HFC, certain employees of HFC are seconded to HLS, our general partner’s general partner, to provide operational and maintenance services with respect to certain of our pipelines, terminals and refinery processing units, including routine operational and maintenance activities. During their period of secondment, the seconded employees are under the management and supervision of HLS. HLS is required to reimburse HFC for our benefit for the cost of the seconded employees, including their wages and benefits, based on the percentage of the employee’s time spent working for HLS. The secondment arrangement continues until HLS’s mutual agreement with HFC to terminate.

PIPELINE AND TERMINAL, TANKAGE AND THROUGHPUT AGREEMENTS

We serve HFC’s refineries and renewable diesel facilities under long-term pipeline, terminal, tankage and refinery processing unit throughput agreements expiring in 2022 to 2036. Under these agreements, HFC agrees to transport, store and process throughput volumes of refined product, crude oil and feedstocks on our pipelines, terminal, tankage and loading rack facilities and refinery processing units that result in minimum annual payments to us. These minimum annual payments or revenues are subject to annual tariff rate adjustments on July 1st each year, based on the PPI or the FERC index. As of December 31, 2021, these agreements with HFC require minimum annualized payments to us of $352.8 million. However, as previously disclosed, our agreements with HFC were modified to account for the conversion of the Cheyenne refinery to renewable diesel production as discussed below, and as of January 1, 2021, require minimum annualized payments to us of $351.1 million.

HFC’s obligations under these agreements will not terminate if HFC and its affiliates no longer own the general partner. These agreements may be assigned by HFC only with the consent of our conflicts committee.

REVIEW, APPROVAL OR RATIFICATION OF TRANSACTIONS WITH RELATED PERSONS

The Board of Directors of our general partner adopted a written related party transactions policy to document procedures for the notification, review, approval, ratification and disclosure of related party transactions. Under the policy, a “related person” includes any director, director nominee, executive officer, or holder (together with any of its controlling or controlled affiliates) of more than 5% percent of our voting units or an immediate family member of any of the foregoing persons or an entity that is owned or controlled by any of the foregoing persons, any of the foregoing persons have a substantial ownership interest or control, or an entity in which any of the foregoing persons is an executive officer or general partner, or holds a similar position. The policy applies to any transaction, arrangement, or relationship or series of similar transactions, arrangements or relationships (including indebtedness or guarantee of indebtedness) in which (i) the aggregate amount involved will or may be expected to exceed $120,000 in any fiscal year, (ii) we, HLS or our subsidiaries are a participant, and (iii) a related person has a direct or indirect material interest.

Certain transactions, including compensation for services provided to a related person, such as an executive officer or director, are pre-approved under the policy. Any transactions between us, our general partner, any of our subsidiaries, on the one hand, and HFC or any of its subsidiaries, on the other hand, shall be submitted to the Conflicts Committee of our general partner for review and approval in accordance with the process established, and under the authority delegated by the Board of Directors of our general partner to the Conflicts Committee of our general partner for the review, evaluation and approval of intercompany transactions and shall not constitute a related party transaction under the policy.

The policy provides that the Audit Committee of our general partner will be responsible for reviewing and approving related party transactions that may arise within our partnership. The Audit Committee will review the material facts of all related party transactions that require the committee’s approval and either approve or disapprove of the entry into the related party transaction. The policy prohibits any director from participating in any discussion or approval of a related party transaction for which such director is a related person, except that such director is required to provide all material information concerning the interested transaction to the committee. Related party transactions required to be disclosed in our SEC reports are reported through our disclosure controls and procedures.

The Code of Business Conduct and Ethics governs conflicts of interests involving employees who are not covered by the related party transaction policy described above. Conflict of interest transactions may be authorized if they are found to be in the best interest of the Partnership based on all relevant facts. Pursuant to the Code of Business Conduct and Ethics, conflicts of interest are to be disclosed to and reviewed by a supervisor who does not have a conflict of interest, the Human Resources Department or the Legal and Compliance Department, and approval must be obtained prior to proceeding with the potentially conflicted situation.

On August 2, 2021, in connection with the Sinclair Transactions, HEP and HFC entered into that certain Letter Agreement pursuant to which, among other things, HEP and HFC agreed, upon the consummation of the Sinclair Transactions, to enter into amendments to certain of the agreements by and among HEP and its affiliates, on the one hand, and HFC and its affiliates (other than HEP and its affiliates), on the other hand, including the Seventh Amended and Restated Master Throughput Agreement, dated February 8, 2021 (as amended from time to time, the “Master Throughput Agreement”), to include within the scope of such agreements the assets to be acquired by HEP pursuant to the Contribution Agreement. The amendment to the Master Throughput Agreement will include minimum volume commitments by HFC in respect of the certain assets acquired by HEP pursuant to the Contribution Agreement, as further described in the Letter Agreement. The amendments to certain of the other agreements between HEP and HFC are described in the Letter Agreement. HFC is the parent company of HLS, our ultimate general partner.

In addition, the Letter Agreement provides that if, as a condition to obtaining antitrust clearance for the Sinclair Transactions, HFC enters into a definitive agreement to divest the Woods Cross Refinery, then HFC and HEP will enter into a purchase agreement in substantially the form attached to the Letter Agreement, pursuant to which HEP and its affiliates would sell their assets located at, or relating to, the Woods Cross Refinery (the “Partnership WX Assets”) to HFC in exchange for cash consideration equal to $232.5 million plus the amount of all accounts receivable of HEP and its affiliates in respect of the Partnership WX Assets as of the closing date, with such sale to be effective immediately prior to the closing of the sale of the Woods Cross Refinery by HFC. The Letter Agreement also provides that HEP’s right to future revenues from HFC in respect of the Partnership WX Assets will terminate at the closing of such sale.

There are no other transactions required to be disclosed in this Item 13 entered into since January 1, 2021, that were required to be reviewed, ratified or approved pursuant to our Related Party Transaction Policy or Code of Business Conduct and Ethics or with respect to which our policies and procedures with respect to conflicts of interest were not followed.

Description of Business and Summary of Significant Accounting Policies

Description of Business and Summary of Significant Accounting Policies

Holly Energy Partners, L.P. (“HEP”) together with its consolidated subsidiaries, is a publicly held master limited partnership. As of December 31, 2021, HollyFrontier Corporation (“HFC”) and its subsidiaries own a 57% limited partner interest and the non-economic general partner interest in HEP. We commenced operations on July 13, 2004, upon the completion of our initial public offering. In these consolidated financial statements, the words “we,” “our,” “ours” and “us” refer to HEP unless the context otherwise indicates.

We own and operate petroleum product and crude oil pipelines, terminal, tankage and loading rack facilities and refinery processing units that support the refining and marketing operations of HFC and other refineries in the Mid-Continent, Southwest and Northwest regions of the United States. Additionally, we own a 75% interest in the UNEV Pipeline, LLC (“UNEV”), a 50% interest in Osage Pipe Line Company, LLC (“Osage”), a 50% interest in Cheyenne Pipeline LLC, and a 50% interest in Cushing Connect Pipeline & Terminal LLC.

On June 1, 2020, HFC announced plans to permanently cease petroleum refining operations at its Cheyenne refinery (the “Cheyenne Refinery”) and to convert certain assets at that refinery to renewable diesel production. HFC subsequently began winding down petroleum refining operations at the Cheyenne refinery on August 3, 2020.

On February 8, 2021, HEP and HFC finalized and executed new agreements for HEP’s Cheyenne assets with the following terms, in each case effective January 1, 2021: (1) a ten-year lease with two five-year renewal option periods for HFC’s use of certain HEP tank and rack assets in the Cheyenne refinery to facilitate renewable diesel production with an annual lease payment of approximately $5 million, (2) a five-year contango service fee arrangement that will utilize HEP tank assets inside the Cheyenne refinery where HFC will pay a base tariff to HEP for available crude oil storage and HFC and HEP will split any profits generated on crude oil contango opportunities and (3) a $10 million one-time cash payment from HFC to HEP for the termination of the existing minimum volume commitment.

On April 1, 2021, we sold our 156-mile, 6-inch refined product pipeline that connected HFC’s Navajo refinery to terminals in El Paso for gross proceeds of $7.0 million and recognized a gain on sale of $5.3 million.

We operate in two reportable segments, a Pipelines and Terminals segment and a Refinery Processing Unit segment. Disclosures around these segments are discussed in Note 16.

Our Pipelines and Terminals segment consists of:

•26 main pipeline segments

•Crude gathering networks in Texas and New Mexico

•10 refined product terminals

•1 crude terminal

•1 lube terminal

•31,800 track feet of rail storage located at two facilities

•7 locations with truck and/or rail racks

•Tankage at 6 of HFC's refining and renewable diesel facility locations

Our Refinery Processing Unit segment consists of five refinery processing units at two of HFC's refining facility locations.

We generate revenues by charging tariffs for transporting petroleum products and crude oil through our pipelines, by charging fees for terminalling and storing refined products and other hydrocarbons, providing other services at our storage tanks and terminals and by charging fees for processing hydrocarbon feedstocks through our refinery processing units. We do not take ownership of products that we transport, terminal, store or process, and therefore, we are not exposed directly to changes in commodity prices.

Principles of Consolidation

The consolidated financial statements include our accounts and those of subsidiaries and joint ventures that we control through an ownership interest greater than 50% or through a controlling financial interest with respect to variable interest entities. All

significant intercompany transactions and balances have been eliminated. Certain prior period balances have been reclassified for consistency with current year presentation.

Use of Estimates

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Cash and Cash Equivalents

For purposes of the statements of cash flows, we consider all highly liquid investments with maturities of three months or less at the time of purchase to be cash equivalents. The carrying amounts reported on the balance sheets approximate fair value due to the short-term maturity of these instruments.

Accounts Receivable

The majority of the accounts receivable are due from affiliates of HFC or independent companies in the petroleum industry. Credit is extended based on evaluation of the customer's financial condition, and in certain circumstances, collateral such as letters of credit or guarantees, may be required. We reserve for doubtful accounts based on our historical loss experience as well as expected credit losses from current economic conditions and management’s expectations of future economic conditions. Credit losses are charged to the allowance for doubtful accounts when an account is deemed uncollectible and historically have been minimal.

Properties and Equipment

Properties and equipment are stated at cost. Properties and equipment acquired from HFC while under common control of HFC are stated at HFC's historical basis. Depreciation is provided by the straight-line method over the estimated useful lives of the assets, primarily 15 to 25 years for terminal facilities and tankage, 25 to 30 years for pipelines, 25 years for refinery processing units and 3 to 10 years for corporate and other assets. We depreciate assets acquired under capital leases over the lesser of the lease term or the economic life of the assets. Maintenance, repairs and minor replacements are expensed as incurred. Costs of replacements constituting improvements are capitalized.

Intangible Assets

Intangible assets include transportation agreements and acquired customer relationship intangible assets. Intangible assets are stated at acquisition date fair value and are being amortized over their useful lives using the straight-line method.

Goodwill and Long-Lived Assets

Goodwill represents the excess of our cost of an acquired business over the fair value of the assets acquired, less liabilities assumed. Goodwill is not amortized. We test goodwill at the reporting unit level for impairment annually and between annual tests if events or changes in circumstances indicate the carrying amount may exceed fair value. Our goodwill impairment testing first entails a comparison of our reporting unit fair values relative to their respective carrying values, including goodwill. If carrying value exceeds the estimated fair value for a reporting unit, we measure goodwill impairment as the excess of the carrying amount of the reporting unit over the estimated fair value of the reporting unit.

The changes due to our new agreements with HFC related to our Cheyenne assets resulted in an increase in the net book value of our Cheyenne reporting unit during the first quarter of 2021 due to sales-type lease accounting, which led us to determine indicators of potential goodwill impairment for our Cheyenne reporting unit were present. Therefore, we performed an interim quantitative review of our Cheyenne reporting unit goodwill for the first quarter of 2021.

The estimated fair value of our Cheyenne reporting unit was derived using a combination of income and market approaches. The income approach reflects expected future cash flows based on anticipated gross margins, operating costs, and capital expenditures. The market approaches include both the guideline public company and guideline transaction methods. Both methods utilize pricing multiples derived from historical market transactions of other like-kind assets. These fair value measurements involve significant unobservable inputs (Level 3 inputs). See Note 6 for further discussion of Level 3 inputs.

Our interim impairment testing of our Cheyenne reporting unit goodwill identified an impairment charge of $11.0 million, which was recorded in the three months ended March 31, 2021.

Our annual goodwill impairment testing for 2021 and 2019 was performed on a qualitative basis during the third quarters of 2021 and 2019. We assessed qualitative factors such as macroeconomic conditions, industry considerations, cost factors and reporting unit financial performance and determined it was not more likely than not that the fair value of our reporting units were less than the respective carrying value. Therefore, in accordance with GAAP, further testing was not required.

Our annual impairment testing for 2020 was performed on a quantitative basis during the third quarter of 2020. The estimated fair value of our reporting units were derived using a combination of both income and market approaches as described above. Our annual testing of goodwill in 2020 identified an impairment charge of $35.7 million, which was recorded in the third quarter of 2020, related to our Cheyenne reporting unit.

The following is a summary of our goodwill balances:

	December 31, 2021		December 31, 2020
	(In thousands)
Goodwill	$	270,336	$	270,336
Accumulated impairment losses	(46,686)		(35,652)
	$	223,650	$	234,684

We evaluate long-lived assets, including finite-lived intangible assets, for potential impairment by identifying whether indicators of impairment exist and, if so, assessing whether the long-lived assets are recoverable from estimated future undiscounted cash flows. The actual amount of impairment loss, if any, to be recorded is equal to the amount by which a long-lived asset’s carrying value exceeds its fair value.

Investment in Equity Method Investments

We account for our interests in noncontrolling joint venture interests using the equity method of accounting, whereby we record our pro-rata share of earnings of these companies, and contributions to and distributions from the joint ventures as adjustments to our investment balances. The difference between the cost of an investment and our proportionate share of the underlying equity in net assets recorded on the investee's books is allocated to the various assets and liabilities of the equity method investment.

The following table summarizes our recorded investments compared to our share of underlying equity for each investee. We are amortizing the differences as adjustments to our pro-rata share of earnings over the useful lives of the underlying assets of these joint ventures.

Total	$	93,196	$	120,544	$	(27,348)

Asset Retirement Obligations

We record legal obligations associated with the retirement of certain of our long-lived assets that result from the acquisition, construction, development and/or the normal operation of our long-lived assets. The fair value of the estimated cost to retire a tangible long-lived asset is recorded in the period in which the liability is incurred and when a reasonable estimate of the fair value of the liability can be made. For our pipeline assets, the right-of-way agreements typically do not require the dismantling, removal and reclamation of the right-of-way upon cessation of the pipeline service. Additionally, management is unable to predict when, or if, our pipelines and related facilities would become obsolete and require decommissioning. Accordingly, we have recorded no liability or corresponding asset related to an asset retirement obligation for the majority of our pipelines as both the amounts and timing of such potential future costs are indeterminable. For our remaining assets, at December 31, 2021 and 2020, we have asset retirement obligations of $8.7 million and $9.0 million, respectively, that are recorded under “Other long-term liabilities” in our consolidated balance sheets.

Class B Unit

Under the terms of the transaction to acquire HFC's 75% interest in UNEV, we issued HFC a Class B unit comprising a noncontrolling equity interest in a wholly-owned subsidiary subject to redemption to the extent that HFC is entitled to a 50% interest in our share of annual UNEV earnings before interest, income taxes, depreciation, and amortization above $30 million beginning July 1, 2015, and ending in June 2032, subject to certain limitations. Such contingent redemption payments are limited to the unredeemed value of the Class B Unit. However, to the extent earnings thresholds are not achieved, no redemption payments are required. No redemption payments have been required to date.

Pursuant to the terms of the transaction agreements, the Class B unit increases by the amount of each foregone incentive distribution and by a 7% factor compounded annually on the outstanding unredeemed balance through its expiration date. At our option, we may redeem, in whole or in part, the Class B unit at the current unredeemed value based on the calculation described. The Class B unit had a carrying value of $56.5 million at December 31, 2021, and $52.9 million at December 31, 2020.

Revenue Recognition

Revenues are generally recognized as products are shipped through our pipelines and terminals, feedstocks are processed through our refinery processing units or other services are rendered. The majority of our contracts with customers meet the definition of a lease since (1) performance of the contracts is dependent on specified property, plant, or equipment and (2) it is remote that one or more parties other than the customer will take more than a minor amount of the output associated with the specified property, plant, or equipment. Prior to the adoption of the new lease standard (see below), we bifurcated the consideration received between lease and service revenue. The new lease standard allows the election of a practical expedient whereby a lessor does not have to separate non-lease (service) components from lease components under certain conditions. The majority of our contracts meet these conditions, and we have made this election for those contracts. Under this practical expedient, we treat the combined components as a single performance obligation in accordance with Accounting Standards Codification (“ASC”) 606, which largely codified ASU 2014-09, if the non-lease (service) component is the dominant component. If the lease component is the dominant component, we treat the combined components as a lease in accordance with ASC 842, which largely codified ASU 2016-02.

Several of our contracts include incentive or reduced tariffs once a certain quarterly volume is met. Revenue from the variable element of these transactions is recognized based on the actual volumes shipped as it relates specifically to rendering the services during the applicable quarter.

The majority of our long-term transportation contracts specify minimum volume requirements, whereby, we bill a customer for a minimum level of shipments in the event a customer ships below their contractual requirements. If there are no future performance obligations, we will recognize these deficiency payments in revenue.

In certain of these throughput agreements, a customer may later utilize such shortfall billings as credit towards future volume shipments in excess of its minimum levels within its respective contractual shortfall make-up period. Such amounts represent an obligation to perform future services, which may be initially deferred and later recognized as revenue based on estimated future shipping levels, including the likelihood of a customer’s ability to utilize such amounts prior to the end of the contractual shortfall make-up period. We recognize these deficiency payments in revenue when we do not expect we will be required to satisfy these performance obligations in the future based on the pattern of rights projected to be exercised by the customer. During the years ended December 31, 2021, 2020 and 2019, we recognized $17.5 million, $20.8 million and $16.0 million, respectively, of these deficiency payments in revenue, of which $0.5 million, $0.7 million and $0.6 million, respectively, related to deficiency payments billed in prior periods. As of December 31, 2021, deferred revenue reflected in our consolidated balance sheet related to shortfalls billed was $4.2 million.

We have other cost reimbursement provisions in our throughput/storage agreements providing that customers (including HFC) reimburse us for certain costs. Such reimbursements are recorded as revenue or deferred revenue depending on the nature of the cost. Deferred revenue is recognized over the remaining contractual term of the related throughput agreement.

Taxes billed and collected from our pipeline and terminal customers are recorded on a net basis with no effect on net income.

Leases

We adopted ASC 842 effective January 1, 2019, and elected to adopt using the modified retrospective transition method and practical expedients, both of which are provided as options by the standard and further defined below.

Lessee Accounting - At inception, we determine if an arrangement is or contains a lease. Right-of-use assets represent our right to use an underlying asset for the lease term, and lease liabilities represent our payment obligation under the leasing arrangement. Right-of-use assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. We use our estimated incremental borrowing rate (“IBR”) to determine the present value of lease payments as most of our leases do not contain an implicit rate. Our IBR represents the interest rate which we would pay to borrow, on a collateralized basis, an amount equal to the lease payments over a similar term in a similar economic environment. We use the implicit rate when readily determinable.

Operating leases are recorded in operating lease right-of-use assets and current and noncurrent operating lease liabilities on our consolidated balance sheet. Finance leases are included in properties and equipment, current finance lease liabilities and noncurrent finance lease liabilities on our consolidated balance sheet.

When renewal options are defined in a lease, our lease term includes an option to extend the lease when it is reasonably certain we will exercise that option. Leases with a term of 12 months or less are not recorded on our balance sheet, and lease expense is accounted for on a straight-line basis. In addition, as a lessee, we separate non-lease components that are identifiable and exclude them from the determination of net present value of lease payment obligations.

Lessor Accounting - Customer contracts that contain leases are generally classified as either operating leases, direct finance leases or sales-type leases. We consider inputs such as the lease term, fair value of the underlying asset and residual value of the underlying assets when assessing the classification.

Environmental Costs

Environmental costs are expensed if they relate to an existing condition caused by past operations and do not contribute to current or future revenue generation. Liabilities are recorded when site restoration and environmental remediation, cleanup and other obligations are either known or considered probable and can be reasonably estimated. Such estimates require judgment with respect to costs, time frame and extent of required remedial and clean-up activities and are subject to periodic adjustments based on currently available information.

Under the Omnibus Agreement and certain transportation agreements and purchase agreements with HFC, HFC has agreed to indemnify us, subject to certain monetary and time limitations, for environmental noncompliance and remediation liabilities associated with certain assets transferred to us from HFC occurring or existing prior to the date of such transfers. We have an

environmental agreement with Delek with respect to pre-closing environmental costs and liabilities relating to the pipelines and terminals acquired from Delek in 2005, under which Delek will indemnify us subject to certain monetary and time limitations. Environmental costs recoverable through insurance, indemnification agreements or other sources are included in other assets to the extent such recoveries are considered probable.

Income Tax

We are subject to the Texas margin tax that is based on our Texas sourced taxable margin. The tax is calculated by applying a tax rate to a base that considers both revenues and expenses and therefore has the characteristics of an income tax.

We are organized as a pass-through entity for U.S. federal income tax purposes. As a result, our partners are responsible for U.S. federal income taxes based on their respective share of taxable income.

Net income for financial statement purposes may differ significantly from taxable income reportable to unitholders as a result of differences between the tax basis and financial reporting basis of assets and liabilities and the taxable income allocation requirements under the partnership agreement.

Accounting Pronouncement Adopted During the Periods Presented

Goodwill Impairment Testing

In January 2017, Accounting Standard Update (“ASU”) 2017-04, “Simplifying the Test for Goodwill Impairment,” was issued amending the testing for goodwill impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measured a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under this standard, goodwill impairment is measured as the excess of the carrying amount of the reporting unit over the related fair value. We adopted this standard effective in the second quarter of 2019, and the adoption of this standard had no effect on our financial condition, results of operations or cash flows for the year ended December 31, 2019.

Leases

In February 2016, ASU No. 2016-02, “Leases” (“ASC 842”) was issued requiring leases to be measured and recognized as a lease liability, with a corresponding right-of-use asset on the balance sheet. We adopted this standard effective January 1, 2019, and we elected to adopt using the modified retrospective transition method, whereby comparative prior period financial information will not be restated and will continue to be reported under the lease accounting standard in effect during those periods. We also elected practical expedients provided by the new standard, including the package of practical expedients and the short-term lease recognition practical expedient, which allows an entity to not recognize on the balance sheet leases with a term of 12 months or less. Upon adoption of this standard, we recognized $78.4 million of lease liabilities and corresponding right-of-use assets on our consolidated balance sheet. See Notes 4 and 5 of Notes to the Consolidated Financial Statements for additional information on our lease policies.

Credit Losses Measurement

In June 2016, ASU 2016-13, “Measurement of Credit Losses on Financial Instruments,” was issued requiring measurement of all expected credit losses for certain types of financial instruments, including trade receivables, held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. This standard was effective January 1, 2020. Adoption of the standard did not have a material impact on our financial condition, results of operations or cash flows.

Accounting Pronouncements - Not Yet Adopted

In October 2021, Accounting Standards Update 2021-08, “Accounting for Contract Assets and Contract Liabilities from Contracts with Customers” was issued requiring that an acquiring entity recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Accounting Standards Codification (“ASC”) 606 – Revenue from Contracts with Customers. This standard is effective for fiscal years beginning after December 15, 2022, and early adoption is permitted. We will evaluate the impact of this standard and consider early adoption, if applicable.

Sinclair Acquisition

Sinclair Acquisition

HEP Transaction

On August 2, 2021, HEP, The Sinclair Companies (“Sinclair”) and Sinclair Transportation Company, a wholly owned subsidiary of Sinclair (“STC”), entered into a Contribution Agreement (the “Contribution Agreement”) pursuant to which HEP will acquire all of the outstanding shares of STC in exchange for 21 million newly issued common units of HEP and cash consideration equal to $325 million (the “HEP Transaction”). On the same date, HFC, Sinclair and certain other parties entered into a Business Combination Agreement pursuant to which Sinclair will contribute all of the equity interests of Hippo Holding LLC, which owns Sinclair Oil Corporation, to a new HFC parent holding company that will be named “HF Sinclair Corporation” in exchange for 60,230,036 shares of common stock in HF Sinclair Corporation (the “HFC Transaction”, and together with the HEP Transaction, the “Sinclair Transactions”).

The cash consideration for the HEP Transaction is subject to customary adjustments at closing for working capital of STC. The number of HEP common units to be issued to Sinclair at closing is subject to downward adjustment if, as a condition to obtaining antitrust clearance for the Sinclair Transactions, HEP agrees to divest a portion of its equity interest in UNEV Pipeline, LLC and the sales price for such interests does not exceed the threshold provided in the Contribution Agreement.

The Contribution Agreement contains customary representations, warranties and covenants of HEP, Sinclair, and STC. The HEP Transaction is expected to close in 2022, subject to the satisfaction or waiver of certain customary conditions, including, among others, the receipt of certain required regulatory consents and clearance, including the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act (the “HSR Act”), and the consummation of the HFC Transaction. On August 23, 2021, each of HFC and Sinclair filed its respective premerger notification and report regarding the Sinclair Transactions with the U.S. Department of Justice and the U.S. Federal Trade Commission (the “FTC”) under the HSR Act. On September 22, 2021, HFC and Sinclair each received a request for additional information and documentary material (“Second Request”) from the FTC in connection with the FTC’s review of the Sinclair Transactions. Issuance of the Second Request extends the waiting period under the HSR Act until 30 days after both HFC and Sinclair have substantially complied with the Second Request, unless the waiting period is terminated earlier by the FTC or the parties otherwise commit not to close the Sinclair Transactions for some additional period of time. HFC and Sinclair are cooperating with the FTC staff in its review and are working diligently to satisfy the closing conditions as soon as possible.

The Contribution Agreement automatically terminates if the HFC Transaction is terminated, and contains other customary termination rights, including a termination right for each of HEP and Sinclair if, under certain circumstances, the closing does not occur by May 2, 2022 (the “Outside Date”), except that the Outside Date can be extended by either party by up to two 90 day periods to obtain any required antitrust clearance.

Upon closing of the HEP Transaction, HEP’s existing senior management team will continue to operate HEP. Under the definitive agreements, Sinclair will be granted the right to nominate one director to the HEP board of directors at the closing. The Sinclair stockholders have also agreed to certain customary lock-up restrictions and registration rights for the HEP common units to be issued to the stockholders of Sinclair. HEP will continue to operate under the name Holly Energy Partners, L.P.

See Note 12 for a description of the Letter Agreement between HFC and HEP entered into in connection with the Contribution Agreement.

Equity Method Investments and Joint Ventures [Abstract]

Investment in Joint Venture

Investment in Joint Venture

On October 2, 2019, HEP Cushing LLC (“HEP Cushing”), a wholly-owned subsidiary of HEP, and Plains Marketing, L.P. (“PMLP”), a wholly-owned subsidiary of Plains All American Pipeline, L.P. (“Plains”), formed a 50/50 joint venture, Cushing Connect Pipeline & Terminal LLC (the “Cushing Connect Joint Venture”), for (i) the development and construction of a new 160,000 barrel per day common carrier crude oil pipeline (the “Cushing Connect Pipeline”) that connected the Cushing, Oklahoma crude oil hub to the Tulsa, Oklahoma refining complex owned by a subsidiary of HFC and (ii) the ownership and operation of 1.5 million barrels of crude oil storage in Cushing, Oklahoma (the “Cushing Connect JV Terminal”). The Cushing Connect JV Terminal went in service during the second quarter of 2020, and the Cushing Connect Pipeline was placed into service during the third quarter of 2021. Long-term commercial agreements were entered into to support the Cushing Connect Joint Venture assets.

The Cushing Connect Joint Venture contracted with an affiliate of HEP to manage the construction and operation of the Cushing Connect Pipeline and with an affiliate of Plains to manage the operation of the Cushing Connect JV Terminal. The total Cushing Connect Joint Venture investment will generally be shared equally among the partners. However, we are solely responsible for any Cushing Connect Pipeline construction costs that exceed the budget by more than 10%. HEP estimates its share of the cost of the Cushing Connect JV Terminal contributed by Plains and Cushing Connect Pipeline construction costs are approximately $70 million to $75 million, including $4 million to $6 million of Cushing Connect Pipeline construction costs exceeding the budget by more than 10% to be borne solely by HEP.

The Cushing Connect Joint Venture legal entities are variable interest entities (“VIEs”) as defined under GAAP. A VIE is a legal entity if it has any one of the following characteristics: (i) the entity does not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support; (ii) the at risk equity holders, as a group, lack the characteristics of a controlling financial interest; or (iii) the entity is structured with non-substantive voting rights. The Cushing Connect Joint Venture legal entities did not have sufficient equity at risk to finance their activities without additional financial support. Since HEP constructed and is operating the Cushing Connect Pipeline, HEP has more ability to direct the activities that most significantly impact the financial performance of the Cushing Connect Joint Venture and Cushing Connect Pipeline legal entities. Therefore, HEP consolidates those legal entities. We do not have the ability to direct the activities that most significantly impact the Cushing Connect JV Terminal legal entity, and therefore, we account for our interest in the Cushing Connect JV Terminal legal entity using the equity method of accounting. HEP's maximum exposure to loss as a result of its involvement with the Cushing Connect JV Terminal legal entity is not expected to be material due to the long-term terminalling agreements in place to support its operations.

With the exception of the assets of HEP Cushing, creditors of the Cushing Connect Joint Venture legal entities have no recourse to our assets. Any recourse to HEP Cushing would be limited to the extent of HEP Cushing's assets, which other than its investment in Cushing Connect Joint Venture, are not significant. Furthermore, our creditors have no recourse to the assets of the Cushing Connect Joint Venture legal entities.

Revenues

Revenues are generally recognized as products are shipped through our pipelines and terminals, feedstocks are processed through our refinery processing units or other services are rendered. See Note 1 for further discussion of revenue recognition.

Disaggregated revenues are as follows:

Lease revenues	$	336,062	$	360,598	$	378,311
Service revenues	158,433		137,250		154,466
	$	494,495	$	497,848	$	532,777

A contract liability exists when an entity is obligated to perform future services to a customer for which the entity has received consideration. Since HEP may be required to perform future services for these deficiency payments received, the deferred revenues on our balance sheets were considered contract liabilities. A contract asset exists when an entity has a right to consideration in exchange for goods or services transferred to a customer. Our consolidated balance sheets included the contract assets and liabilities in the table below.

	December 31, 2021		December 31, 2020
	(In thousands)
Contract assets	$	6,637	$	6,306
Contract liabilities	$	(4,185)	$	(500)

The contract assets and liabilities include both lease and service components. During the years ended December 31, 2021 and 2020, we recognized $0.5 million and $0.7 million, respectively, of revenue that was previously included in contract liability as of December 31, 2020 and 2019, respectively. During the twelve months ended December 31, 2021, 2020 and 2019, we also recognized $0.3 million and $0.6 million and $3.9 million, respectively, of revenue included in contract assets at December 31, 2021.

As of December 31, 2021, we expect to recognize $1.6 billion in revenue related to our unfulfilled performance obligations under the terms of our long-term throughput agreements and operating leases expiring in 2022 through 2036. These agreements provide for changes in the minimum revenue guarantees annually for increases or decreases in the Producer Price Index (“PPI”) or Federal Energy Regulatory Commission (“FERC”) index, with certain contracts having provisions that limit the level of the rate increases or decreases. We expect to recognize revenue for these unfulfilled performance obligations as shown in the table below (amounts shown in table include both service and lease revenues):

Years Ending December 31,	(In millions)
2022	312
2023	275
2024	238
2025	172
2026	157
Thereafter	484
Total	$	1,638

Payment terms under our contracts with customers are consistent with industry norms and are typically payable within 10 to 30 days of the date of invoice.

Leases

We adopted ASC 842 effective January 1, 2019, and elected to adopt using the modified retrospective transition method and practical expedients, both of which are provided as options by the standard and further defined in Note 1. See Note 1 for further discussion of lease accounting.

Lessee Accounting

As a lessee, we lease land, buildings, pipelines, transportation and other equipment to support our operations. These leases can be categorized into operating and finance leases.

Our leases have remaining terms of less than 1 year to 23 years, some of which include options to extend the leases for up to 10 years.

Finance Lease Obligations

We have finance lease obligations related to vehicle leases with initial terms of 33 to 48 months. The total cost of assets under finance leases was $6.0 million and $6.4 million as of December 31, 2021 and December 31, 2020, respectively, with accumulated depreciation of $3.6 million and $3.4 million as of December 31, 2021 and December 31, 2020, respectively. We include depreciation of finance leases in depreciation and amortization in our consolidated statements of income.

In addition, we have a finance lease obligation related to a pipeline lease with an initial term of 10 years with one remaining subsequent renewal option for an additional 10 years.

Lessor Accounting

As discussed in Note 1, the majority of our contracts with customers meet the definition of a lease. See Note 1 for further discussion of the impact of adoption of this standard on our activities as a lessor.

Substantially all of the assets supporting contracts meeting the definition of a lease have long useful lives, and we believe these assets will continue to have value when the current agreements expire due to our risk management strategy for protecting the residual fair value of the underlying assets by performing ongoing maintenance during the lease term. HFC generally has the option to purchase assets located within HFC refinery boundaries, including refinery tankage, truck racks and refinery processing units, at fair market value when the related agreements expire.

During the year ended December 31, 2021, we entered into new agreements, and amended other agreements, with HFC related to our Cheyenne assets, Tulsa West lube racks, various crude tanks and new Navajo tanks, and the agreements we previously entered into relating to the Cushing Connect Pipeline became effective. These agreements met the criteria of sales-type leases since the underlying assets are not expected to have an alternative use at the end of the lease terms to anyone other than HFC. Under sales-type lease accounting, at the commencement date, the lessor recognizes a net investment in the lease, based on the estimated fair value of the underlying leased assets at contract inception, and derecognizes the underlying assets with the difference recorded as selling profit or loss arising from the lease. Therefore, we recognized a gain on sales-type leases during the year ended December 31, 2021 composed of the following:

	(In thousands)
Net investment in leases	$	148,419
Properties and equipment, net	(130,301)
Deferred Revenue	6,559
Gain on sales-type leases	$	24,677

During the year ended December 31, 2020, one of our throughput agreements with Delek US Holdings, Inc. (“Delek”) was partially renewed. A component of this agreement met the criteria of a sales-type lease since the underlying asset is not expected to have an alternative use at the end of the lease term to anyone other than Delek. We recognized a gain on sales-type leases during the year ended December 31, 2020 composed of the following:

	(In thousands)
Net investment in leases	$	35,319
Properties and equipment, net	(1,485)
Gain on sales-type leases	$	33,834

These sales-type lease transactions, including the related gains, were non-cash transactions.

Lease income recognized was as follows:

Sales-type lease interest income	27,836		8,481
Lease revenues relating to variable lease payments not included in measurement of the sales-type lease receivable	9,160		9,929

For our sales-type leases, we included customer obligations related to minimum volume requirements in guaranteed minimum lease payments. Portions of our minimum guaranteed pipeline tariffs for assets subject to sales-type lease accounting are recorded as interest income with the remaining amounts recorded as a reduction in net investment in leases. We recognized any billings for throughput volumes in excess of minimum volume requirements as variable lease payments, and these variable lease payments were recorded in lease revenues.

Annual minimum undiscounted lease payment receipts under our leases were as follows as of December 31, 2021:

Lessor Accounting

As discussed in Note 1, the majority of our contracts with customers meet the definition of a lease. See Note 1 for further discussion of the impact of adoption of this standard on our activities as a lessor.

Substantially all of the assets supporting contracts meeting the definition of a lease have long useful lives, and we believe these assets will continue to have value when the current agreements expire due to our risk management strategy for protecting the residual fair value of the underlying assets by performing ongoing maintenance during the lease term. HFC generally has the option to purchase assets located within HFC refinery boundaries, including refinery tankage, truck racks and refinery processing units, at fair market value when the related agreements expire.

During the year ended December 31, 2021, we entered into new agreements, and amended other agreements, with HFC related to our Cheyenne assets, Tulsa West lube racks, various crude tanks and new Navajo tanks, and the agreements we previously entered into relating to the Cushing Connect Pipeline became effective. These agreements met the criteria of sales-type leases since the underlying assets are not expected to have an alternative use at the end of the lease terms to anyone other than HFC. Under sales-type lease accounting, at the commencement date, the lessor recognizes a net investment in the lease, based on the estimated fair value of the underlying leased assets at contract inception, and derecognizes the underlying assets with the difference recorded as selling profit or loss arising from the lease. Therefore, we recognized a gain on sales-type leases during the year ended December 31, 2021 composed of the following:

	(In thousands)
Net investment in leases	$	148,419
Properties and equipment, net	(130,301)
Deferred Revenue	6,559
Gain on sales-type leases	$	24,677

During the year ended December 31, 2020, one of our throughput agreements with Delek US Holdings, Inc. (“Delek”) was partially renewed. A component of this agreement met the criteria of a sales-type lease since the underlying asset is not expected to have an alternative use at the end of the lease term to anyone other than Delek. We recognized a gain on sales-type leases during the year ended December 31, 2020 composed of the following:

	(In thousands)
Net investment in leases	$	35,319

For our sales-type leases, we included customer obligations related to minimum volume requirements in guaranteed minimum lease payments. Portions of our minimum guaranteed pipeline tariffs for assets subject to sales-type lease accounting are recorded as interest income with the remaining amounts recorded as a reduction in net investment in leases. We recognized any billings for throughput volumes in excess of minimum volume requirements as variable lease payments, and these variable lease payments were recorded in lease revenues.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are derived using inputs (assumptions that market participants would use in pricing an asset or liability) including assumptions about risk. GAAP categorizes inputs used in fair value measurements into three broad levels as follows:

•(Level 1) Quoted prices in active markets for identical assets or liabilities.

•(Level 2) Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, similar assets and liabilities in markets that are not active or can be corroborated by observable market data.

•(Level 3) Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes valuation techniques that involve significant unobservable inputs.

Financial Instruments

Our financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, and debt. The carrying amounts of cash equivalents, accounts receivable and accounts payable approximate fair value due to the short-term maturity of these instruments. Debt consists of outstanding principal under our revolving credit agreement (which approximates fair value as interest rates are reset frequently at current interest rates) and our fixed interest rate senior notes.

The carrying amounts and estimated fair values of our senior notes were as follows:

		December 31, 2021				December 31, 2020
Financial Instrument	Fair Value Input Level	Carrying Value		Fair Value		Carrying Value		Fair Value
		(In thousands)
Liabilities:
5% Senior Notes	Level 2	$	493,049	$	502,705	$	492,103	$	506,540

Level 2 Financial Instruments

Our senior notes are measured at fair value using Level 2 inputs. The fair value of the senior notes is based on market values provided by a third-party bank, which were derived using market quotes for similar type debt instruments. See Note 10 for additional information.

Non-Recurring Fair Value Measurements

For gains on sales-type leases recognized during the years ended December 31, 2021 and 2020, the estimated fair value of the underlying leased assets at contract inception and the present value of the estimated unguaranteed residual asset at the end of the lease term are used in determining the net investment in leases and related gain on sales-type leases recorded. The asset valuation estimates include Level 3 inputs based on a replacement cost valuation method.

During the years ended December 31, 2021 and 2020, we recognized goodwill impairment based on fair value measurements utilized during our goodwill testing (see Note 1). The fair value measurements were based on a combination of valuation methods including discounted cash flows and the guideline public company and guideline transaction methods; all of which are Level 3 inputs.

Intangible Assets

Intangible AssetsIntangible assets include transportation agreements and customer relationships that represent a portion of the total purchase price of certain assets acquired from Delek in 2005, from HFC in 2008 prior to HEP becoming a consolidated VIE of HFC, from Plains in 2017, and from other minor acquisitions in 2018.

The carrying amounts of our intangible assets are as follows:

Amortization expense was $14.0 million for the years ended December 31, 2021, 2020 and 2019, respectively. We estimate amortization expense to be $14.0 million for 2022, $9.9 million for 2023, and $9.1 million for 2024, 2025, and 2026.

We have additional transportation agreements with HFC resulting from historical transactions consisting of pipeline, terminal and tankage assets contributed to us or acquired from HFC. These transactions occurred while we were a consolidated variable interest entity of HFC; therefore, our basis in these agreements is zero and does not reflect a step-up in basis to fair value.

Share-based Payment Arrangement [Abstract]

Employees, Retirement and Incentive Plans

Employees, Retirement and Incentive Plans

Direct support for our operations is provided by Holly Logistic Services, L.L.C., (“HLS”), an HFC subsidiary, which utilizes personnel employed by HFC who are dedicated to performing services for us. Their costs, including salaries, bonuses, payroll taxes, benefits and other direct costs, are charged to us monthly in accordance with an omnibus agreement that we have with HFC. These employees participate in the retirement and benefit plans of HFC. Our share of retirement and benefit plan costs was $8.7 million, $7.9 million and $7.3 million for the years ended December 31, 2021, 2020 and 2019, respectively. These costs include retirement costs of $3.7 million, $3.4 million and $3.4 million for the years ended December 31, 2021, 2020 and 2019, respectively.

Under HLS’s secondment agreement with HFC (the “Secondment Agreement”), certain employees of HFC are seconded to HLS to provide operational and maintenance services for certain of our processing, refining, pipeline and tankage assets, and HLS reimburses HFC for its prorated portion of the wages, benefits, and other costs related to these employees.

We have a Long-Term Incentive Plan for employees and non-employee directors who perform services for us. The Long-Term Incentive Plan consists of five components: restricted or phantom units, performance units, unit options, unit appreciation rights and cash awards. Our accounting policy for the recognition of compensation expense for awards with pro-rata vesting (a significant proportion of our awards) is to expense the costs ratably over the vesting periods.

As of December 31, 2021, we have two types of unit-based awards outstanding, which are described below. The compensation cost charged against income was $2.6 million, $2.2 million and $2.5 million for the years ended December 31, 2021, 2020 and 2019, respectively. We currently purchase units in the open market instead of issuing new units for settlement of all unit awards under our Long-Term Incentive Plan. As of December 31, 2021, 2,500,000 units were authorized to be granted under our Long-Term Incentive Plan, of which 753,425 have not yet been granted, assuming no forfeitures of the unvested units and full achievement of goals for the unvested performance units.

Phantom Units

Under our Long-Term Incentive Plan, we grant phantom units to non-employee directors and selected employees who perform services for us, with most awards vesting over a period of one to three years. Although full ownership of the units does not transfer to the recipients until the units vest, the recipients have distribution rights on these units from the date of grant.

The fair value of each phantom unit award is measured at the market price as of the date of grant and is amortized on a straight-line basis over the requisite service period for each separately vesting portion of the award.

A summary of phantom unit activity and changes during the year ended December 31, 2021, is presented below: 

Phantom Units	Units	Weighted- Average Grant-Date Fair Value
Outstanding at January 1, 2021 (nonvested)	295,992	$	14.48
Granted	51,670	18.93
Vesting and transfer of common units to recipients	(137,566)	15.56
Forfeited	(6,833)	15.54
Outstanding at December 31, 2021 (nonvested)	203,263	14.85

The grant date fair values of restricted or phantom units that were vested and transferred to recipients during the years ended December 31, 2021, 2020 and 2019 were $2.1 million, $2.0 million and $2.1 million, respectively. As of December 31, 2021, there was $1.8 million of total unrecognized compensation expense related to unvested phantom unit grants, which is expected to be recognized over a weighted-average period of 1.4 years. For the years ended December 31, 2020 and 2019, the grant date price applied to the number of restricted or phantom units awarded was $11.92 and $23.52, respectively.

Performance Units

Under our Long-Term Incentive Plan, we grant performance units to selected executives who perform services for us. Performance units granted are payable in common units at the end of a three-year performance period based upon meeting certain criteria over the performance period. Under the terms of our performance unit grants, some awards are subject to the growth in our distributable cash flow per common unit over the performance period while other awards are subject to “financial performance” and “market performance.” Financial performance is based on meeting certain earnings before interest, taxes, depreciation and amortization (“EBITDA”) targets, while market performance is based on the relative standing of total unitholder return achieved by HEP compared to peer group companies. The number of units ultimately issued under these awards can range from 0% to 200%.

Although common units are not transferred to the recipients until the performance units vest, the recipients have distribution rights with respect to the target number of performance units subject to the award from the date of grant at the same rate as distributions paid on our common units.

A summary of performance unit activity and changes for the year ended December 31, 2021, is presented below:

Performance Units	Units
Outstanding at January 1, 2021 (nonvested)	77,472
Granted	10,128
Vesting and transfer of common units to recipients	(10,881)
Outstanding at December 31, 2021 (nonvested)	76,719

The grant date fair values of performance units vested and transferred to recipients were $0.4 million, $0.4 million and $0.3 million for the years ended December 31, 2021, 2020 and 2019, respectively. Based on the weighted average fair value of performance units outstanding at December 31, 2021, of $1.4 million, there was $0.6 million of total unrecognized compensation expense related to nonvested performance units, which is expected to be recognized over a weighted-average period of 1.5 years.

During the year ended December 31, 2021, we paid $2.0 million for the purchase of our common units in the open market for the issuance and settlement of unit awards under our Long-Term Incentive Plan.

Credit Agreement

In April 2021, we amended our senior secured revolving credit facility (the “Credit Agreement”) decreasing the size of the facility from $1.4 billion to $1.2 billion and extending the maturity date to July 27, 2025. The Credit Agreement is available to fund capital expenditures, investments, acquisitions, distribution payments, working capital and for general partnership purposes. The Credit Agreement is also available to fund letters of credit up to a $50 million sub-limit and continues to provide for an accordion feature that allows us to increase commitments under the Credit Agreement up to a maximum amount of $1.7 billion.

Our obligations under the Credit Agreement are collateralized by substantially all of our assets, and indebtedness under the Credit Agreement is guaranteed by our material, wholly-owned subsidiaries. The Credit Agreement requires us to maintain compliance with certain financial covenants consisting of total leverage, senior secured leverage, and interest coverage. It also limits or restricts our ability to engage in certain activities. If, at any time prior to the expiration of the Credit Agreement, HEP obtains two investment grade credit ratings, the Credit Agreement will become unsecured and many of the covenants, limitations, and restrictions will be eliminated.

We may prepay all loans at any time without penalty, except for tranche breakage costs. If an event of default exists under the Credit Agreement, the lenders will be able to accelerate the maturity of all loans outstanding and exercising other rights and remedies. We were in compliance with the covenants as of December 31, 2021.

Senior Notes

On February 4, 2020, we closed a private placement of $500 million in aggregate principal amount of 5% senior unsecured notes due in 2028 (the “5% Senior Notes”). On February 5, 2020, we redeemed the existing $500 million 6% Senior Notes at a redemption cost of $522.5 million, at which time we recognized a $25.9 million early extinguishment loss consisting of a $22.5 million debt redemption premium and unamortized financing costs of $3.4 million. We funded the $522.5 million redemption with proceeds from the issuance of our 5% Senior Notes and borrowings under our Credit Agreement.

The 5% Senior Notes are unsecured and impose certain restrictive covenants, including limitations on our ability to incur additional indebtedness, make investments, sell assets, incur certain liens, pay distributions, enter into transactions with affiliates, and enter into mergers. At any time when the 5% Senior Notes are rated investment grade by either Moody’s or Standard & Poor’s and no default or event of default exists, we will not be subject to many of the foregoing covenants. Additionally, we have certain redemption rights at varying premiums over face value under the 5% Senior Notes.

Indebtedness under the 5% Senior Notes is guaranteed by our wholly-owned subsidiaries (other than Holly Energy Finance Corp. and certain immaterial subsidiaries).

Commitments and Contingencies

We lease certain facilities and pipelines under operating leases and finance leases, most of which contain renewal options. These operating leases have various termination dates through 2035. See Note 5 for a schedule of annual minimum undiscounted lease payments under our leases as of December 31, 2021. As of December 31, 2021, we expect to receive aggregate payments totaling $1.0 million over the life of our noncancelable sublease of office space, expiring in 2026.

We also have other long-term contractual obligations consisting of long-term site service agreements with HFC, expiring in 2058 through 2066, for the provision of certain facility services and utility costs that relate to our assets located at HFC’s refinery and renewable diesel facilities. We are presenting obligations for the full term of these agreements; however, the agreements can be terminated with 180 day notice if we cease to operate the applicable assets.

In addition, we have long-term contractual obligations associated with rights-of-way agreements, which have various termination dates through 2099. The related payments below include only obligations under the remaining non-cancelable terms of these agreements at December 31, 2021.

At December 31, 2021, these minimum future contractual obligations and other miscellaneous obligations having terms in excess of one year are as follows:

Related Party Transactions

Related Party Transactions

We serve HFC’s refinery and renewable diesel facilities under long-term pipeline, terminal and tankage throughput agreements, and refinery processing unit tolling agreements expiring from 2022 to 2036, and revenues from these agreements accounted for approximately 79% of our total revenues for the year ended December 31, 2021. Under these agreements, HFC agrees to transport, store, and process throughput volumes of refined product, crude oil and feedstocks on our pipelines, terminals, tankage, loading rack facilities and refinery processing units that result in minimum annual payments to us. These minimum annual payments or revenues are generally subject to annual rate adjustments on July 1st each year based on increases or decreases in the Producer Price Index (“PPI”) or FERC index. As of December 31, 2021, these agreements with HFC require minimum annualized payments to us of $352.8 million.

If HFC fails to meet its minimum volume commitments under the agreements in any quarter, it will be required to pay us the amount of any shortfall in cash by the last day of the month following the end of the quarter. Under certain of these agreements, a shortfall payment may be applied as a credit in the following four quarters after its minimum obligations are met.

Under certain provisions of the Omnibus Agreement, we pay HFC an annual administrative fee (currently $2.6 million) for the provision by HFC or its affiliates of various general and administrative services to us. This fee does not include the salaries of personnel employed by HFC who perform services for us on behalf of HLS or the cost of their employee benefits, which are charged to us separately by HFC. Also, we reimburse HFC and its affiliates for direct expenses they incur on our behalf.

Related party transactions with HFC are as follows:

•Revenues received from HFC were $390.8 million, $399.8 million and $411.8 million for the years ended December 31, 2021, 2020 and 2019, respectively.

•HFC charged us general and administrative services under the Omnibus Agreement of $2.6 million for each of the years ended December 31, 2021, 2020 and 2019.

•We reimbursed HFC for costs of employees supporting our operations of $61.2 million, $55.8 million and $55.1 million for the years ended December 31, 2021, 2020 and 2019, respectively.

•HFC reimbursed us $7.9 million, $10.0 million and $13.9 million for the years ended December 31, 2021, 2020 and 2019, respectively, for expense and capital projects.

•We distributed $83.5 million, $95.2 million and $150.0 million in the years ended December 31, 2021, 2020 and 2019 respectively, to HFC as regular distributions on its common units.

•Accounts receivable from HFC were $56.2 million and $48.0 million at December 31, 2021 and 2020, respectively.

•Accounts payable to HFC were $11.7 million and $18.1 million at December 31, 2021 and 2020, respectively.

•Revenues for the years ended December 31, 2021, 2020 and 2019 include $0.4 million, $0.5 million and $0.5 million, respectively, of shortfall payments billed to HFC in 2020, 2019 and 2018, respectively. Deferred revenue in the consolidated balance sheets at December 31, 2021 and 2020, includes $4.1 million and $0.4 million, respectively, relating to certain shortfall billings to HFC.

•We received direct financing lease payments from HFC for use of our Artesia and Tulsa railyards of $2.1 million for each of the years ended December 31, 2021, 2020 and 2019 .

•We recorded a gain on sales-type leases with HFC of $24.7 million and $35.2 million during the year ended December 31, 2021 and December 31, 2019, respectively, and we received sales-type lease payments of $28.9 million, $9.5 million and $4.8 million from HFC that were not included in revenues for the years ended December 31, 2021, 2020 and 2019, respectively.

•HEP and HFC reached an agreement to terminate the existing minimum volume commitments for HEP's Cheyenne assets and enter into new agreements, which were finalized and executed on February 8, 2021, with the following terms, in each case effective January 1, 2021: (1) a ten-year lease with two five-year renewal option periods for HFC’s use of certain HEP tank and rack assets in the Cheyenne refinery to facilitate renewable diesel production with an annual lease payment of approximately $5 million, (2) a five-year contango service fee arrangement that will utilize HEP tank assets inside the Cheyenne refinery where HFC will pay a base tariff to HEP for available crude oil storage

and HFC and HEP will split any profits generated on crude oil contango opportunities and (3) a $10 million one-time cash payment from HFC to HEP for the termination of the existing minimum volume commitment.

On August 2, 2021, in connection with the Sinclair Transactions (described in Note 2 above), HEP and HFC entered into a Letter Agreement (“Letter Agreement”) pursuant to which, among other things, HEP and HFC agreed, upon the consummation of the Sinclair Transactions, to enter into amendments to certain of the agreements by and among HEP and HFC, including the master throughput agreement, to include within the scope of such agreements the assets to be acquired by HEP pursuant to the Contribution Agreement (described in Note 2 above).

In addition, the Letter Agreement provides that if, as a condition to obtaining antitrust clearance for the Sinclair Transactions, HFC enters into a definitive agreement to divest its refinery in Davis County, Utah (the “Woods Cross Refinery”), then HEP would sell certain assets located at, or relating to, the Woods Cross Refinery to HFC in exchange for cash consideration equal to $232.5 million plus the certain accounts receivable of HEP in respect of such assets, with such sale to be effective immediately prior to the closing of the sale of the Woods Cross Refinery by HFC. The Letter Agreement also provides that HEP’s right to future revenues from HFC in respect of such Woods Cross Refinery assets will terminate at the closing of such sale.

At December 31, 2021, HFC held 59,630,030 of our common units, constituting a 57% limited partner interest in us and held the non-economic general partner interest.

Continuous Offering Program

We have a continuous offering program under which we may issue and sell common units from time to time, representing limited partner interests, up to an aggregate gross sales amount of $200 million. As of December 31, 2021, HEP had issued 2,413,153 units under this program, providing $82.3 million in gross proceeds.

Allocations of Net Income

Net income attributable to the partners is allocated to the partners based on their weighted-average ownership percentage during the period.

Cash Distributions

We consider regular cash distributions to unitholders on a quarterly basis, although there is no assurance as to the future cash distributions since they are dependent upon future earnings, cash flows, capital requirements, financial condition and other factors.

Within 45 days after the end of each quarter, we distribute all of our available cash (as defined in our partnership agreement) to unitholders of record on the applicable record date. The amount of available cash generally is all cash on hand at the end of the quarter; less the amount of cash reserves established by our general partner to provide for the proper conduct of our business, comply with applicable laws, any of our debt instruments, or other agreements; or provide funds for distributions to our unitholders and to our general partner for any one or more of the next four quarters; plus all cash on hand on the date of determination of available cash for the quarter resulting from working capital borrowings made after the end of the quarter.

On January 21, 2022, we announced our cash distribution for the fourth quarter of 2021 of $0.35 per unit. The distribution was payable on all common units and was paid February 11, 2022, to all unitholders of record on February 1, 2022.

We paid cash distributions totaling $149.4 million, $174.4 million and $273.2 million for the years ended December 31, 2021, 2020 and 2019, respectively.

Net Income Per Limited Partner Unit

Net Income per Limited Partner Unit [Abstract]

Net Income per Limited Partner Unit

Net Income Per Limited Partner Unit Basic net income per unit applicable to the limited partners is calculated as net income attributable to the partners, adjusted for participating securities’ share in earnings, divided by the weighted average limited partners’ units outstanding. Diluted net

income per unit assumes, when dilutive, the issuance of the net incremental units from phantom units and performance units. To the extent net income attributable to the partners exceeds or is less than cash distributions, this difference is allocated to the partners based on their weighted-average ownership percentage during the period. Our dilutive securities are immaterial for all periods presented.

Net income per limited partner unit is computed as follows:

Environmental Remediation Obligations [Abstract]

Environmental

We expensed $1.9 million, $1.6 million and $0.5 million for the years ended December 31, 2021, 2020 and 2019, respectively, for environmental remediation obligations. The accrued environmental liability related to environmental clean-up projects for which we have assumed liability or for which indemnity provided by HFC has expired reflected in our consolidated balance sheets was $3.9 million and $4.5 million as of December 31, 2021 and 2020, respectively, of which $2.4 million and $2.5 million, respectively, were classified as other long-term liabilities. These accruals include remediation and monitoring costs expected to be incurred over an extended period of time.

Under the Omnibus Agreement and certain transportation agreements and purchase agreements with HFC, HFC has agreed to indemnify us, subject to certain monetary and time limitations, for environmental noncompliance and remediation liabilities associated with certain assets transferred to us from HFC and occurring or existing prior to the date of such transfers. As of December 31, 2021 and 2020, our consolidated balance sheets included additional accrued environmental liabilities of $0.3 million and $0.5 million for HFC indemnified liabilities, respectively, and other assets included equal and offsetting balances representing amounts due from HFC related to indemnifications for environmental remediation liabilities.

Segment Reporting [Abstract]

Operating Segments

Operating Segments

Although financial information is reviewed by our chief operating decision makers from a variety of perspectives, they view the business in two reportable operating segments: (1) pipelines and terminals and (2) refinery processing units. These segments adhere to the accounting polices used for our consolidated financial statements. For a discussion of these accounting policies and a summary of our reportable operating segments' assets and derivation of revenue, see Note 1.

Pipelines and terminals have been aggregated as one reportable segment as both pipelines and terminals (1) have similar economic characteristics, (2) similarly provide logistics services of transportation and storage of petroleum products, (3) similarly support the petroleum refining business, including distribution of its products, (4) have principally the same customers and (5) are subject to similar regulatory requirements.

We evaluate the performance of each segment based on its respective operating income. Certain general and administrative expenses and interest and financing costs are excluded from segment operating income as they are not directly attributable to a specific reportable segment. Identifiable assets are those used by the segment, whereas other assets are principally equity method investments, cash, deposits and other assets that are not associated with a specific reportable segment.

Supplemental Guarantor / Non-Guarantor Financial Information [Abstract]

Supplemental Guarantor / Non-Guarantor Financial Information

Supplemental Guarantor/Non-Guarantor Financial Information Obligations of HEP (“Parent”) under the 5% Senior Notes have been jointly and severally guaranteed by each of its direct and indirect 100% owned subsidiaries (“Guarantor Subsidiaries”). These guarantees are full and unconditional, subject to certain customary release provisions. These circumstances include (i) when a Guarantor Subsidiary is sold or sells all or substantially all of its assets, (ii) when a Guarantor Subsidiary is declared “unrestricted” for covenant purposes, (iii) when a Guarantor Subsidiary's guarantee of other indebtedness is terminated or released and (iv) when the requirements for legal defeasance or covenant defeasance or to discharge the senior notes have been satisfied.

The following financial information presents condensed consolidating balance sheets, statements of comprehensive income, and statements of cash flows of the Parent, the Guarantor Subsidiaries and the Non-Guarantor subsidiaries. The information has been presented as if the Parent accounted for its ownership in the Guarantor Subsidiaries and the Guarantor Restricted Subsidiaries accounted for the ownership of the Non-Guarantor Non-Restricted Subsidiaries, using the equity method of accounting.

Description of Business and Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2021

Accounting Policies [Abstract]

Principles of Consolidation

Principles of Consolidation

The consolidated financial statements include our accounts and those of subsidiaries and joint ventures that we control through an ownership interest greater than 50% or through a controlling financial interest with respect to variable interest entities. All

significant intercompany transactions and balances have been eliminated. Certain prior period balances have been reclassified for consistency with current year presentation.

Use of Estimates

Use of Estimates

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Cash and Cash Equivalents

Cash and Cash Equivalents

For purposes of the statements of cash flows, we consider all highly liquid investments with maturities of three months or less at the time of purchase to be cash equivalents. The carrying amounts reported on the balance sheets approximate fair value due to the short-term maturity of these instruments.

Accounts Receivable

Accounts Receivable

The majority of the accounts receivable are due from affiliates of HFC or independent companies in the petroleum industry. Credit is extended based on evaluation of the customer's financial condition, and in certain circumstances, collateral such as letters of credit or guarantees, may be required. We reserve for doubtful accounts based on our historical loss experience as well as expected credit losses from current economic conditions and management’s expectations of future economic conditions. Credit losses are charged to the allowance for doubtful accounts when an account is deemed uncollectible and historically have been minimal.

Properties and Equipment

Properties and Equipment

Properties and equipment are stated at cost. Properties and equipment acquired from HFC while under common control of HFC are stated at HFC's historical basis. Depreciation is provided by the straight-line method over the estimated useful lives of the assets, primarily 15 to 25 years for terminal facilities and tankage, 25 to 30 years for pipelines, 25 years for refinery processing units and 3 to 10 years for corporate and other assets. We depreciate assets acquired under capital leases over the lesser of the lease term or the economic life of the assets. Maintenance, repairs and minor replacements are expensed as incurred. Costs of replacements constituting improvements are capitalized.

Intangible Assets

Intangible Assets

Intangible assets include transportation agreements and acquired customer relationship intangible assets. Intangible assets are stated at acquisition date fair value and are being amortized over their useful lives using the straight-line method.

Goodwill and Long-Lived Assets

Goodwill and Long-Lived Assets

Goodwill represents the excess of our cost of an acquired business over the fair value of the assets acquired, less liabilities assumed. Goodwill is not amortized. We test goodwill at the reporting unit level for impairment annually and between annual tests if events or changes in circumstances indicate the carrying amount may exceed fair value. Our goodwill impairment testing first entails a comparison of our reporting unit fair values relative to their respective carrying values, including goodwill. If carrying value exceeds the estimated fair value for a reporting unit, we measure goodwill impairment as the excess of the carrying amount of the reporting unit over the estimated fair value of the reporting unit.

The changes due to our new agreements with HFC related to our Cheyenne assets resulted in an increase in the net book value of our Cheyenne reporting unit during the first quarter of 2021 due to sales-type lease accounting, which led us to determine indicators of potential goodwill impairment for our Cheyenne reporting unit were present. Therefore, we performed an interim quantitative review of our Cheyenne reporting unit goodwill for the first quarter of 2021.

The estimated fair value of our Cheyenne reporting unit was derived using a combination of income and market approaches. The income approach reflects expected future cash flows based on anticipated gross margins, operating costs, and capital expenditures. The market approaches include both the guideline public company and guideline transaction methods. Both methods utilize pricing multiples derived from historical market transactions of other like-kind assets. These fair value measurements involve significant unobservable inputs (Level 3 inputs). See Note 6 for further discussion of Level 3 inputs.

Our interim impairment testing of our Cheyenne reporting unit goodwill identified an impairment charge of $11.0 million, which was recorded in the three months ended March 31, 2021.

Our annual goodwill impairment testing for 2021 and 2019 was performed on a qualitative basis during the third quarters of 2021 and 2019. We assessed qualitative factors such as macroeconomic conditions, industry considerations, cost factors and reporting unit financial performance and determined it was not more likely than not that the fair value of our reporting units were less than the respective carrying value. Therefore, in accordance with GAAP, further testing was not required.

Our annual impairment testing for 2020 was performed on a quantitative basis during the third quarter of 2020. The estimated fair value of our reporting units were derived using a combination of both income and market approaches as described above. Our annual testing of goodwill in 2020 identified an impairment charge of $35.7 million, which was recorded in the third quarter of 2020, related to our Cheyenne reporting unit.

The following is a summary of our goodwill balances:

	December 31, 2021		December 31, 2020
	(In thousands)
Goodwill	$	270,336	$	270,336
Accumulated impairment losses	(46,686)		(35,652)
	$	223,650	$	234,684

We evaluate long-lived assets, including finite-lived intangible assets, for potential impairment by identifying whether indicators of impairment exist and, if so, assessing whether the long-lived assets are recoverable from estimated future undiscounted cash flows. The actual amount of impairment loss, if any, to be recorded is equal to the amount by which a long-lived asset’s carrying value exceeds its fair value.

Investment in Equity Method Investments

Investment in Equity Method Investments

We account for our interests in noncontrolling joint venture interests using the equity method of accounting, whereby we record our pro-rata share of earnings of these companies, and contributions to and distributions from the joint ventures as adjustments to our investment balances. The difference between the cost of an investment and our proportionate share of the underlying equity in net assets recorded on the investee's books is allocated to the various assets and liabilities of the equity method investment.

Asset Retirement Obligations

Asset Retirement Obligations We record legal obligations associated with the retirement of certain of our long-lived assets that result from the acquisition, construction, development and/or the normal operation of our long-lived assets. The fair value of the estimated cost to retire a tangible long-lived asset is recorded in the period in which the liability is incurred and when a reasonable estimate of the fair value of the liability can be made. For our pipeline assets, the right-of-way agreements typically do not require the dismantling, removal and reclamation of the right-of-way upon cessation of the pipeline service. Additionally, management is unable to predict when, or if, our pipelines and related facilities would become obsolete and require decommissioning. Accordingly, we have recorded no liability or corresponding asset related to an asset retirement obligation for the majority of our pipelines as both the amounts and timing of such potential future costs are indeterminable. For our remaining assets, at December 31, 2021 and 2020, we have asset retirement obligations of $8.7 million and $9.0 million, respectively, that are recorded under “Other long-term liabilities” in our consolidated balance sheets.

Class B Unit

Class B Unit

Under the terms of the transaction to acquire HFC's 75% interest in UNEV, we issued HFC a Class B unit comprising a noncontrolling equity interest in a wholly-owned subsidiary subject to redemption to the extent that HFC is entitled to a 50% interest in our share of annual UNEV earnings before interest, income taxes, depreciation, and amortization above $30 million beginning July 1, 2015, and ending in June 2032, subject to certain limitations. Such contingent redemption payments are limited to the unredeemed value of the Class B Unit. However, to the extent earnings thresholds are not achieved, no redemption payments are required. No redemption payments have been required to date.

Pursuant to the terms of the transaction agreements, the Class B unit increases by the amount of each foregone incentive distribution and by a 7% factor compounded annually on the outstanding unredeemed balance through its expiration date. At our option, we may redeem, in whole or in part, the Class B unit at the current unredeemed value based on the calculation described. The Class B unit had a carrying value of $56.5 million at December 31, 2021, and $52.9 million at December 31, 2020.

Revenue Recognition

Revenue Recognition

Revenues are generally recognized as products are shipped through our pipelines and terminals, feedstocks are processed through our refinery processing units or other services are rendered. The majority of our contracts with customers meet the definition of a lease since (1) performance of the contracts is dependent on specified property, plant, or equipment and (2) it is remote that one or more parties other than the customer will take more than a minor amount of the output associated with the specified property, plant, or equipment. Prior to the adoption of the new lease standard (see below), we bifurcated the consideration received between lease and service revenue. The new lease standard allows the election of a practical expedient whereby a lessor does not have to separate non-lease (service) components from lease components under certain conditions. The majority of our contracts meet these conditions, and we have made this election for those contracts. Under this practical expedient, we treat the combined components as a single performance obligation in accordance with Accounting Standards Codification (“ASC”) 606, which largely codified ASU 2014-09, if the non-lease (service) component is the dominant component. If the lease component is the dominant component, we treat the combined components as a lease in accordance with ASC 842, which largely codified ASU 2016-02.

Several of our contracts include incentive or reduced tariffs once a certain quarterly volume is met. Revenue from the variable element of these transactions is recognized based on the actual volumes shipped as it relates specifically to rendering the services during the applicable quarter.

The majority of our long-term transportation contracts specify minimum volume requirements, whereby, we bill a customer for a minimum level of shipments in the event a customer ships below their contractual requirements. If there are no future performance obligations, we will recognize these deficiency payments in revenue.

In certain of these throughput agreements, a customer may later utilize such shortfall billings as credit towards future volume shipments in excess of its minimum levels within its respective contractual shortfall make-up period. Such amounts represent an obligation to perform future services, which may be initially deferred and later recognized as revenue based on estimated future shipping levels, including the likelihood of a customer’s ability to utilize such amounts prior to the end of the contractual shortfall make-up period. We recognize these deficiency payments in revenue when we do not expect we will be required to satisfy these performance obligations in the future based on the pattern of rights projected to be exercised by the customer. During the years ended December 31, 2021, 2020 and 2019, we recognized $17.5 million, $20.8 million and $16.0 million, respectively, of these deficiency payments in revenue, of which $0.5 million, $0.7 million and $0.6 million, respectively, related to deficiency payments billed in prior periods. As of December 31, 2021, deferred revenue reflected in our consolidated balance sheet related to shortfalls billed was $4.2 million.

We have other cost reimbursement provisions in our throughput/storage agreements providing that customers (including HFC) reimburse us for certain costs. Such reimbursements are recorded as revenue or deferred revenue depending on the nature of the cost. Deferred revenue is recognized over the remaining contractual term of the related throughput agreement.

Taxes billed and collected from our pipeline and terminal customers are recorded on a net basis with no effect on net income.

Lessee Accounting

Lessee Accounting - At inception, we determine if an arrangement is or contains a lease. Right-of-use assets represent our right to use an underlying asset for the lease term, and lease liabilities represent our payment obligation under the leasing arrangement. Right-of-use assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. We use our estimated incremental borrowing rate (“IBR”) to determine the present value of lease payments as most of our leases do not contain an implicit rate. Our IBR represents the interest rate which we would pay to borrow, on a collateralized basis, an amount equal to the lease payments over a similar term in a similar economic environment. We use the implicit rate when readily determinable.

Operating leases are recorded in operating lease right-of-use assets and current and noncurrent operating lease liabilities on our consolidated balance sheet. Finance leases are included in properties and equipment, current finance lease liabilities and noncurrent finance lease liabilities on our consolidated balance sheet.

When renewal options are defined in a lease, our lease term includes an option to extend the lease when it is reasonably certain we will exercise that option. Leases with a term of 12 months or less are not recorded on our balance sheet, and lease expense is accounted for on a straight-line basis. In addition, as a lessee, we separate non-lease components that are identifiable and exclude them from the determination of net present value of lease payment obligations.

Lessor Accounting

Lessor Accounting - Customer contracts that contain leases are generally classified as either operating leases, direct finance leases or sales-type leases. We consider inputs such as the lease term, fair value of the underlying asset and residual value of the underlying assets when assessing the classification.

Environmental Costs

Environmental Costs

Environmental costs are expensed if they relate to an existing condition caused by past operations and do not contribute to current or future revenue generation. Liabilities are recorded when site restoration and environmental remediation, cleanup and other obligations are either known or considered probable and can be reasonably estimated. Such estimates require judgment with respect to costs, time frame and extent of required remedial and clean-up activities and are subject to periodic adjustments based on currently available information.

Under the Omnibus Agreement and certain transportation agreements and purchase agreements with HFC, HFC has agreed to indemnify us, subject to certain monetary and time limitations, for environmental noncompliance and remediation liabilities associated with certain assets transferred to us from HFC occurring or existing prior to the date of such transfers. We have an

environmental agreement with Delek with respect to pre-closing environmental costs and liabilities relating to the pipelines and terminals acquired from Delek in 2005, under which Delek will indemnify us subject to certain monetary and time limitations. Environmental costs recoverable through insurance, indemnification agreements or other sources are included in other assets to the extent such recoveries are considered probable.

Income Tax

Income Tax

We are subject to the Texas margin tax that is based on our Texas sourced taxable margin. The tax is calculated by applying a tax rate to a base that considers both revenues and expenses and therefore has the characteristics of an income tax.

We are organized as a pass-through entity for U.S. federal income tax purposes. As a result, our partners are responsible for U.S. federal income taxes based on their respective share of taxable income.

Net income for financial statement purposes may differ significantly from taxable income reportable to unitholders as a result of differences between the tax basis and financial reporting basis of assets and liabilities and the taxable income allocation requirements under the partnership agreement.

Accounting Pronouncement Adopted During the Periods Presented

Accounting Pronouncement Adopted During the Periods Presented

Goodwill Impairment Testing

In January 2017, Accounting Standard Update (“ASU”) 2017-04, “Simplifying the Test for Goodwill Impairment,” was issued amending the testing for goodwill impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measured a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under this standard, goodwill impairment is measured as the excess of the carrying amount of the reporting unit over the related fair value. We adopted this standard effective in the second quarter of 2019, and the adoption of this standard had no effect on our financial condition, results of operations or cash flows for the year ended December 31, 2019.

Leases

In February 2016, ASU No. 2016-02, “Leases” (“ASC 842”) was issued requiring leases to be measured and recognized as a lease liability, with a corresponding right-of-use asset on the balance sheet. We adopted this standard effective January 1, 2019, and we elected to adopt using the modified retrospective transition method, whereby comparative prior period financial information will not be restated and will continue to be reported under the lease accounting standard in effect during those periods. We also elected practical expedients provided by the new standard, including the package of practical expedients and the short-term lease recognition practical expedient, which allows an entity to not recognize on the balance sheet leases with a term of 12 months or less. Upon adoption of this standard, we recognized $78.4 million of lease liabilities and corresponding right-of-use assets on our consolidated balance sheet. See Notes 4 and 5 of Notes to the Consolidated Financial Statements for additional information on our lease policies.

Credit Losses Measurement

In June 2016, ASU 2016-13, “Measurement of Credit Losses on Financial Instruments,” was issued requiring measurement of all expected credit losses for certain types of financial instruments, including trade receivables, held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. This standard was effective January 1, 2020. Adoption of the standard did not have a material impact on our financial condition, results of operations or cash flows.

Accounting Pronouncements - Not Yet Adopted

In October 2021, Accounting Standards Update 2021-08, “Accounting for Contract Assets and Contract Liabilities from Contracts with Customers” was issued requiring that an acquiring entity recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Accounting Standards Codification (“ASC”) 606 – Revenue from Contracts with Customers. This standard is effective for fiscal years beginning after December 15, 2022, and early adoption is permitted. We will evaluate the impact of this standard and consider early adoption, if applicable.

Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are derived using inputs (assumptions that market participants would use in pricing an asset or liability) including assumptions about risk. GAAP categorizes inputs used in fair value measurements into three broad levels as follows:

•(Level 1) Quoted prices in active markets for identical assets or liabilities.

•(Level 2) Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, similar assets and liabilities in markets that are not active or can be corroborated by observable market data.

•(Level 3) Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes valuation techniques that involve significant unobservable inputs.
