Delek US Holdings, Inc.

Notes to Condensed Consolidated Financial Statements (Unaudited)

1. Organization and Basis of Presentation

Delek US Holdings, Inc. is the sole shareholder or owner of membership interests of Delek Refining, Inc. ("Refining"), Delek Finance, Inc., Delek Marketing & Supply, LLC, Lion Oil Company ("Lion Oil"), Delek Renewables, LLC, Delek Rail Logistics, Inc., Delek Logistics Services Company, MAPCO Express, Inc. ("MAPCO Express"), MAPCO Fleet, Inc., NTI Investments, LLC, GDK Bearpaw, LLC, Delek Helena, LLC, Commerce Way Insurance Company, Inc., Delek Transportation, LLC and Delek Land Holdings, LLC. Unless otherwise indicated or the context requires otherwise, the terms "we," "our," "us," "Delek" and the "Company" are used in this report to refer to Delek US Holdings, Inc. and its consolidated subsidiaries. Delek is listed on the New York Stock Exchange under the symbol "DK."

Our condensed consolidated financial statements include the accounts of Delek and its consolidated subsidiaries. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. Generally Accepted Accounting Principles ("GAAP") have been condensed or omitted, although management believes that the disclosures herein are adequate to make the financial information presented not misleading. Our unaudited condensed consolidated financial statements have been prepared in conformity with GAAP applied on a consistent basis with those of the annual audited financial statements included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission ("SEC") on February 29, 2016 (the "Annual Report on Form 10-K") and in accordance with the rules and regulations of the SEC. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto for the year ended December 31, 2015 included in our Annual Report on Form 10-K.

Our condensed consolidated financial statements include Delek Logistics Partners, LP ("Delek Logistics"), a variable interest entity. As the general partner of Delek Logistics, we have the sole ability to direct the activities of Delek Logistics that most significantly impact its economic performance. We are also considered to be the primary beneficiary for accounting purposes and are Delek Logistics' primary customer. As Delek Logistics does not derive an amount of gross margin material to us from third parties, there is limited risk to Delek associated with Delek Logistics' operations. However, in the event that Delek Logistics incurs a loss, our operating results will reflect Delek Logistics' loss, net of intercompany eliminations, to the extent of our ownership interest in Delek Logistics.

In the opinion of management, all adjustments necessary for a fair presentation of the financial position and the results of operations for the interim periods have been included. All significant intercompany transactions and account balances have been eliminated in consolidation. All adjustments are of a normal, recurring nature. Operating results for the interim period should not be viewed as representative of results that may be expected for any future interim period or for the full year.

Certain prior period amounts have been reclassified in order to conform to the current year presentation. Additionally, we corrected an immaterial error in the prior period in the consolidated statement of cash flows.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

New Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board ("FASB") issued guidance that requires organizations to use historical experience, current conditions, reasonable and supportable forecasts and forward-looking information in the measurement of all expected credit losses on financial instruments to more accurately estimate those losses. This guidance is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted after December 15, 2018, and interim periods within those fiscal years. We expect to adopt this guidance on or before the effective date and are currently evaluating the impact adopting this new guidance will have on our business, financial condition or results of operations.

In March 2016, the FASB issued guidance that simplifies several aspects of the accounting for share-based payment award transactions, including the accounting for excess tax benefits and deficiencies, classification of awards as either equity or liabilities and classification of excess tax benefits on the statement of cash flows. This guidance is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years and can be early adopted for any interim or annual financial statements that have not yet been issued. Early adoption is permitted. We expect to adopt this guidance on or before the effective date and are currently evaluating the impact adopting this new guidance will have on our business, financial condition or results of operations.

In February 2016, the FASB issued guidance that requires the recognition of a lease liability and a right-of-use asset, initially measured at the present value of the lease payments, in the statement of financial position for all leases previously accounted for as operating leases. This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is

7

permitted. We expect to adopt this guidance on or before the effective date and are currently evaluating the impact adopting this new guidance will have on our business, financial condition or results of operations.

In February 2015, the FASB issued guidance that amends and simplifies the requirements for consolidation and provides additional guidance to reporting entities in evaluating whether certain legal entities, such as limited partnerships, limited liability corporations and securitization structures, should be consolidated. This guidance is effective for interim and annual periods beginning after December 15, 2015. We adopted this guidance on the effective date and the adoption did not have a material impact on our business, financial condition or results of operations.

2. Delek Logistics

Delek Logistics is a publicly traded limited partnership that was formed by Delek to own, operate, acquire and construct crude oil and refined products logistics and marketing assets. A substantial majority of Delek Logistics' assets are integral to Delek’s refining and marketing operations. As of June 30, 2016, we owned a 59.7% limited partner interest in Delek Logistics, consisting of 14,798,516 common units, and a 95.1% interest in Logistics GP, which owns the entire 2.0% general partner interest, consisting of 495,975 general partner units, in Delek Logistics and all of the incentive distribution rights.

We have agreements with Delek Logistics that, among other things, establish fees for certain administrative and operational services provided by us and our subsidiaries to Delek Logistics, provide certain indemnification obligations and establish terms for fee-based commercial logistics and marketing services provided by Delek Logistics and its subsidiaries to us.

Delek Logistics is a variable interest entity as defined under GAAP and is consolidated into our condensed consolidated financial statements. With the exception of intercompany balances which are eliminated in consolidation, the Delek Logistics condensed consolidated balance sheets as of June 30, 2016 and December 31, 2015, as presented below, are included in the consolidated balance sheets of Delek (unaudited, in millions).

3. Equity Method Investments

On May 14, 2015, Delek acquired from Alon Israel Oil Company, Ltd. ("Alon Israel") approximately 33.7 million shares of common stock (the "ALJ Shares") of Alon USA Energy, Inc. (NYSE: ALJ) ("Alon USA") pursuant to the terms of a stock purchase agreement with Alon Israel dated April 14, 2015 (the "Alon Acquisition"). The ALJ Shares represented an equity interest in Alon USA of approximately 48%. We acquired the ALJ Shares for the following combination of cash, stock and seller-financed debt:

• Delek issued 6,000,000 restricted shares of its common stock, par value $0.01 per share, to Alon Israel;

• Delek issued an unsecured $145.0 million term promissory note payable to Alon Israel (the "Alon Israel Note") (see Note 6 for further information);

• Delek paid Alon Israel $200.0 million in cash at closing funded with a combination of cash on hand and borrowings under the Lion Term Loan (as defined in Note 6); and

• Delek agreed to pay Alon Israel $5.0 million of additional cash consideration, to be paid ratably in annual installments over a period of five years.

Delek will also issue an additional 200,000 restricted shares of its common stock to Alon Israel if the closing price of Delek's common stock is greater than $50.00 per share for at least 30 consecutive trading days that end on or before May 14, 2017.

As of June 30, 2016, our investment balance in Alon USA was $526.4 million and the excess of our initial investment over our net equity in the underlying net assets of Alon USA was approximately $258.1 million. This excess is included in equity method investments in our consolidated balance sheet and a portion has been attributed to property, plant and equipment and definite lived intangible assets. These portions of the excess are being amortized as a reduction to earnings from equity method investments on a straight-line basis over the lives of the related assets. The earnings or losses from this equity method investment reflected in our consolidated statements of income include our share of net earnings or losses directly attributable to this equity method investment, and amortization of the excess of our investment balance over the underlying net assets of Alon USA. As of June 30, 2016, the market value of our ALJ Shares was $218.3 million, based on quoted market prices. We evaluated our investment in Alon USA as of June 30, 2016 and have determined that the decline in the market value of the ALJ Shares is not other than temporary and, therefore, it was not necessary to record an impairment charge on our investment at June 30, 2016. In determining whether the decline is other than temporary, we considered the cyclical nature of our industry, Alon USA's historical performance, its performance in relation to its peers and the current economic environment.

Below is summarized financial information of the financial position and results of operations of Alon USA (in millions):

Balance Sheet Information	June 30, 2016		December 31, 2015

Also, in March 2015, Delek Logistics entered into two joint ventures that are currently constructing logistics assets, which will serve third parties and subsidiaries of Delek. Delek Logistics' investment in these joint ventures is expected to be financed through a combination of cash from operations and borrowings under the DKL Revolver (as defined in Note 6). As of June 30, 2016, Delek Logistics' investment balance in these joint ventures was $73.4 million and was accounted for using the equity method. One of the joint venture projects is expected to be operational in August 2016.

4. Inventory

Refinery inventory consists of crude oil, work-in-process, refined products and blendstocks which are stated at the lower of cost or market.

Cost of inventory for the El Dorado refinery is determined on a first-in, first-out ("FIFO") basis. Cost of crude oil, refined product and feedstock inventories in excess of market value are charged to cost of goods sold.

Logistics inventory consists of refined products which are stated at the lower of FIFO cost or market.

Retail inventory consists of gasoline, diesel fuel, other petroleum products, cigarettes, beer, convenience merchandise and food service merchandise. Fuel inventories are stated at the lower of FIFO cost or market. Non-fuel inventories are stated at estimated cost as determined by the retail inventory method.

Carrying value of inventories consisted of the following (in millions):

	June 30, 2016		December 31, 2015
Refinery raw materials and supplies	$	154.7	$	85.9
Refinery work in process	39.7		27.8
Refinery finished goods	165.8		146.8
Retail fuel	10.2		9.5
Retail merchandise	27.6		27.1
Logistics refined products	9.8		10.5
Total inventories	$	407.8	$	307.6

Due to a lower crude oil and refined product pricing environment experienced since the end of 2014, market prices have declined to a level below the average cost of our inventories. At June 30, 2016, we recorded a pre-tax lower of cost or market reserve of $32.8 million, of which $31.7 million related to LIFO inventory, which is subject to reversal in subsequent periods, not to exceed LIFO cost, should market prices recover. At December 31, 2015, we recorded a pre-tax lower of cost or market reserve of $50.9 million, of which $49.8 million related to LIFO inventory, which reversed in the first quarter of 2016, as the inventories associated with the valuation adjustment at the end of 2015 were sold or used. We recognized net lower of cost or market gains of $13.0 million and $16.9 million for the three and six months ended June 30, 2016, respectively, and $29.9 million and $31.9 million for the three and six months ended June 30, 2015, respectively. These gains were recorded as a component of cost of goods sold in the consolidated statements of income.

At June 30, 2016 and December 31, 2015, the excess of replacement cost (FIFO) over the carrying value (LIFO) of the Tyler refinery inventories was $0.5 million and $0.1 million, respectively.

Permanent Liquidations

We incurred a permanent reduction in a LIFO layer resulting in a liquidation gain (loss) in our refinery inventory of $0.9 million and $(2.4) million during the three and six months ended June 30, 2016, respectively, and $(6.6) million and $(10.2) million during the three and six months ended June 30, 2015, respectively. These liquidations were recognized as a component of cost of goods sold.

5. Crude Oil Supply and Inventory Purchase Agreement

Delek has a Master Supply and Offtake Agreement (the "Supply and Offtake Agreement") with J. Aron & Company ("J. Aron"). Throughout the term of the Supply and Offtake Agreement, which will expire on April 30, 2017, Lion Oil and J. Aron will identify mutually acceptable contracts for the purchase of crude oil from third parties and J. Aron will supply up to 100,000 barrels per day ("bpd") of crude to the El Dorado refinery. Crude oil supplied to the El Dorado refinery by J. Aron will be purchased daily at an estimated average monthly market price by Lion Oil. J. Aron will also purchase all refined products from the El Dorado refinery at an estimated market price daily, as they are produced. These daily purchases and sales are trued-up on a monthly basis in order to reflect actual average monthly prices. We have recorded a payable related to this monthly settlement of $3.4 million and $11.4 million as of June 30, 2016 and December 31, 2015, respectively. Also pursuant to the Supply and Offtake Agreement and other related agreements, Lion Oil will endeavor to arrange potential sales by either Lion Oil or J. Aron to third parties of the products produced at the El Dorado refinery or purchased from third parties. In instances where Lion Oil is the seller to such third parties, J. Aron will first transfer the applicable products to Lion Oil.

While title to the inventories is retained by J. Aron, this arrangement is accounted for as a product financing arrangement. Delek incurred fees payable to J. Aron of $2.6 million and $5.0 million during the three and six months ended June 30, 2016, respectively, and $2.8 million and $5.3 million during the three and six months ended June 30, 2015, respectively. These amounts are included as a component of interest expense

10

in the condensed consolidated statements of income. Upon any termination of the Supply and Offtake Agreement, including in connection with a force majeure event, the parties are required to negotiate with third parties for the assignment to us of certain contracts, commitments and arrangements, including procurement contracts, commitments for the sale of product, and pipeline, terminalling, storage and shipping arrangements.

Upon the expiration of the Supply and Offtake Agreement on April 30, 2017, or upon any earlier termination, Delek will be required to repurchase the consigned crude oil and refined products from J. Aron at then prevailing market prices. At June 30, 2016, Delek had 3.0 million barrels of inventory consigned for J. Aron, and we have recorded liabilities associated with this consigned inventory of $129.8 million in the condensed consolidated balance sheet.

MAPCO Revolver

Our subsidiary, MAPCO Express, has a revolving credit facility with Fifth Third Bank, as administrative agent, and a syndicate of lenders that was amended and restated on May 6, 2014 (the "MAPCO Revolver"). The MAPCO Revolver consists of a $160.0 million revolving credit limit which includes (i) a $10.0 million swing line loan sub-limit; (ii) a $40.0 million letter of credit sub-limit; and (iii) an accordion feature which permits an increase in borrowings by up to $50.0 million, subject to additional lender commitments. As of June 30, 2016, we had $106.5 million outstanding under the MAPCO Revolver, as well as letters of credit issued of $2.9 million, with approximately $50.6 million of unused credit commitments. Borrowings under the MAPCO Revolver are secured by (i) substantially all the assets of MAPCO Express and its subsidiaries, subject to certain exceptions and limitations, (ii) all of Delek’s shares in MAPCO Express, and (iii) a limited guaranty provided by Delek of up to $50.0 million in obligations. The MAPCO Revolver will mature on May 6, 2019. The MAPCO Revolver bears interest based on predetermined pricing grids which allow us to choose between base rate loans or London Interbank Offered Rate ("LIBOR") rate loans. At June 30, 2016, the weighted average borrowing rate under the MAPCO Revolver was approximately 3.1%. Additionally, the MAPCO Revolver requires us to pay a leverage ratio dependent quarterly fee on the average unused revolving commitment. As of June 30, 2016, this fee was 0.35% per year.

DKL Revolver

Delek Logistics has a $700.0 million senior secured revolving credit agreement with Fifth Third Bank, as administrative agent, and a syndicate of lenders (the "DKL Revolver"). Delek Logistics and each of its existing subsidiaries are borrowers under the DKL Revolver. The DKL Revolver contains a dual currency borrowing tranche that permits draw downs in U.S. or Canadian dollars and an accordion feature whereby Delek Logistics can increase the size of the credit facility to an aggregate of $800.0 million, subject to receiving increased or new commitments from lenders and the satisfaction of certain other conditions precedent.

The obligations under the DKL Revolver are secured by a first priority lien on substantially all of Delek Logistics' tangible and intangible assets. Additionally, a subsidiary of Delek provides a limited guaranty of Delek Logistics' obligations under the DKL Revolver. The guaranty is (i) limited to an amount equal to the principal amount, plus unpaid and accrued interest, of a promissory note made by Delek in favor of the

11

subsidiary guarantor (the "Holdings Note") and (ii) secured by the subsidiary guarantor's pledge of the Holdings Note to the DKL Revolver lenders. As of June 30, 2016, the principal amount of the Holdings Note was $102.0 million.

The DKL Revolver will mature on December 30, 2019. Borrowings under the DKL Revolver bear interest at either a U.S. base rate, Canadian prime rate, LIBOR, or a Canadian Dealer Offered Rate, in each case plus applicable margins, at the election of the borrowers and as a function of draw down currency. The applicable margin, in each case, varies based upon Delek Logistics' leverage ratio, which is defined as the ratio of total funded debt to EBITDA for the most recently ended four fiscal quarters. At June 30, 2016, the weighted average borrowing rate was approximately 2.8%. Additionally, the DKL Revolver requires Delek Logistics to pay a leverage ratio dependent quarterly fee on the average unused revolving commitment. As of June 30, 2016, this fee was 0.40% per year. As of June 30, 2016, Delek Logistics had approximately $362.6 million of outstanding borrowings under the credit facility, as well as letters of credit issued of $7.5 million. Unused credit commitments under the DKL Revolver, as of June 30, 2016, were approximately $329.9 million.

Wells ABL

Our subsidiary, Delek Refining, Ltd., has an asset-based loan credit facility with Wells Fargo Bank, National Association, as administrative agent, and a syndicate of lenders (the "Wells ABL") that consists of (i) a $600.0 million revolving loan (the "Wells Revolving Loan"), which includes a $55.0 million swing line loan sub-limit and a $550.0 million letter of credit sub-limit, (ii) a $70.0 million delayed single draw term loan (the "Wells Term Loan"), and (iii) an accordion feature which permits an increase in the size of the revolving credit facility to an aggregate of $875.0 million, subject to additional lender commitments and the satisfaction of certain other conditions precedent. The Wells Revolving Loan matures on January 16, 2019 and the Wells Term Loan matures on December 31, 2016. The Wells Term Loan is subject to repayment in level principal installments of approximately $5.8 million per quarter, with a final balloon payment due on December 31, 2016. As of June 30, 2016, under the Wells ABL, we had letters of credit issued totaling approximately $91.5 million and no amounts outstanding under the Wells Revolving Loan; under the Wells Term Loan we had approximately $29.2 million outstanding. The obligations under the Wells ABL are secured by (i) substantially all the assets of Refining and its subsidiaries, with certain limitations, (ii) a limited guarantee provided by Delek in an amount up to $15.0 million and (iii) a limited guarantee provided by Lion Oil in an amount equal to the sum of the face amount of all letters of credit issued on behalf of Lion Oil under the Wells ABL and any loans made by Refining or its subsidiaries to Lion Oil. Under the facility, revolving loans and letters of credit are provided subject to availability requirements which are determined pursuant to a borrowing base calculation as defined in the credit agreement. The borrowing base as calculated is primarily supported by cash, certain accounts receivable and certain inventory. Borrowings under the Wells Revolving Loan and Wells Term Loan bear interest based on separate predetermined pricing grids which allow us to choose between base rate loans or LIBOR rate loans. At June 30, 2016, the weighted average borrowing rate under the Wells Term Loan was approximately 4.2%. Additionally, the Wells ABL requires us to pay a quarterly unused credit commitment fee. As of June 30, 2016, this fee was approximately 0.38% per year. Unused borrowing base availability, as calculated and reported under the terms of the Wells ABL credit facility, as of June 30, 2016, was $244.2 million.

Reliant Bank Revolver

We have a revolving credit agreement with Reliant Bank, which was amended on May 26, 2016 (the "Reliant Bank Revolver"). The Reliant Bank Revolver provides for unsecured loans of up to $17.0 million. As of June 30, 2016, we had $17.0 million outstanding under this facility. The Reliant Bank Revolver matures on June 28, 2018, and bears interest at a fixed rate of 5.25% per annum. The Reliant Bank Revolver requires us to pay a quarterly fee of 0.50% per year on the average available revolving commitment. As of June 30, 2016, we had no unused credit commitments under the Reliant Bank Revolver.

Promissory Notes

In 2011, Delek began construction on new MAPCO Mart convenience stores (each a "Build-to-Suit Development" or "BTS"). In order to fund these construction projects, we entered into separate notes for each BTS project with Standard Insurance Company (collectively, the "Notes") varying in size from approximately $1.0 million to $2.2 million. The Notes bear interest at fixed rates, ranging from 5.0% to approximately 6.4% per annum. Each of the Notes is secured by the land or leasehold interest, as applicable, and the building and equipment of its respective completed MAPCO Mart. Under the terms of each Note, beginning on the first day of the eleventh month following the initial fund advancement, payments of principal on each respective Note are due over a ten-year term calculated using a 25-year amortization schedule. If any Note is not paid in full after the initial ten-year period, we may continue to make monthly payments under the Note; however, the interest rate will reset pursuant to the terms of the Note. There is also an additional interest rate reset after the first 20-year period. The final maturity dates of the Notes range from June 1, 2036 to December 1, 2041. As of June 30, 2016, we had amounts drawn under 33 Notes related to these BTS projects, for a total amount of approximately $53.0 million outstanding under the Notes.

On April 29, 2011, Delek entered into a $50.0 million promissory note (the "Ergon Note") with Ergon, Inc. ("Ergon") in connection with the closing of our acquisition of Lion Oil. As of June 30, 2016, $10.0 million was outstanding under the Ergon Note. The Ergon Note requires Delek to make annual amortization payments of $10.0 million each, commencing April 29, 2013. The Ergon Note matures on April 29, 2017. Interest under the Ergon Note is computed at a fixed rate equal to 4.00% per annum.

12

On May 14, 2015, in connection with the closing of the Company’s acquisition of the ALJ Shares, the Company issued the Alon Israel Note, which was payable to Alon Israel. The Alon Israel Note bears interest at a fixed rate of 5.50% per annum and requires five annual principal amortization payments of $25.0 million beginning in January 2016 followed by a final principal amortization payment of $20.0 million at maturity on January 4, 2021. In October 2015, we prepaid the first annual principal amortization payment in the amount of $25.0 million, along with all interest due on the prepaid amount. On December 22, 2015, Alon Israel assigned the remaining $120.0 million of principal and all accrued interest due under the Alon Israel Note to assignees under four new notes in substantially the same form and on the same terms as the Alon Israel Note (collectively, the "Alon Successor Notes"). The $120.0 million in total principal of the four Alon Successor Notes collectively require the same principal amortization payments and schedule as under the Alon Israel Note, with payments due under each Alon Successor Note commensurate to such note's pro rata share of $120.0 million in assigned principal. As of June 30, 2016, a total principal amount of $120.0 million was outstanding under the Alon Successor Notes.

Lion Term Loan

Our subsidiary, Lion Oil, has a term loan credit facility with Fifth Third Bank, as administrative agent, and a syndicate of lenders, which was amended and restated on May 14, 2015 in connection with the Company’s closing of the Alon Acquisition to, among other things, increase the total loan size from $99.0 million to $275.0 million (the "Lion Term Loan"). The Lion Term Loan requires Lion Oil to make quarterly principal amortization payments of approximately $6.9 million each, commencing on September 30, 2015, with a final balloon payment due at maturity on May 14, 2020. The Lion Term Loan is secured by, among other things, (i) substantially all the assets of Lion Oil and its subsidiaries (excluding inventory and accounts receivable), (ii) all shares in Lion Oil, (iii) any subordinated and common units of Delek Logistics held by Lion Oil, and (iv) the ALJ Shares. Additionally, the Lion Term Loan is guaranteed by Delek and the subsidiaries of Lion Oil. Interest on the unpaid balance of the Lion Term Loan is computed at a rate per annum equal to LIBOR or a base rate, at our election, plus the applicable margins, subject in each case to an all-in interest rate floor of 5.50% per annum. As of June 30, 2016, $247.5 million was outstanding under the Lion Term Loan and the weighted average borrowing rate was 5.50%.

Restrictive Covenants

Under the terms of our MAPCO Revolver, Wells ABL, DKL Revolver, Reliant Bank Revolver and Lion Term Loan, we are required to comply with certain usual and customary financial and non-financial covenants. Further, although we were not required to comply with separate fixed charge coverage ratio financial covenants under the Wells ABL and the Lion Term Loan during the three and six months ended June 30, 2016, we may be required to comply with these covenants at times when certain trigger thresholds are met, as defined in each of the Wells ABL and Lion Term Loan agreements. We believe we were in compliance with all covenant requirements under each of our credit facilities as of June 30, 2016.

Certain of our credit facilities contain limitations on the incurrence of additional indebtedness, making of investments, creation of liens, dispositions of property, making of restricted payments and transactions with affiliates. Specifically, these covenants may limit the payment, in the form of cash or other assets, of dividends or other distributions, or the repurchase of shares with respect to the equity of our subsidiaries. Additionally, certain of our credit facilities limit our ability to make investments, including extensions of loans or advances to, or acquisitions of equity interests in, or guarantees of obligations of, any other entities.

Interest-Rate Derivative Instruments

Delek had an interest rate cap agreement in place for a notional amount of $45.0 million, which matured in February 2016. This agreement, and similar interest rate hedge agreements in place that matured during 2015, were intended to economically hedge floating interest rate risk related to a portion of our existing debt. However, as we have elected not to apply the permitted hedge accounting treatment, including formal hedge designation and documentation, in accordance with the provisions of Accounting Standards Codification ("ASC") 815, Derivatives and Hedging ("ASC 815"), the fair value of the derivatives is recorded in other current assets in the accompanying condensed consolidated balance sheets with the offset recognized in interest expense in the accompanying condensed consolidated statements of income. The interest rate cap agreement had no fair value as of December 31, 2015.

In accordance with ASC 815, we recorded expense representing cash settlements and changes in estimated fair value of the interest rate derivative agreements of $0.1 million and $0.2 million for the three and six months ended June 30, 2015. This amount is included in interest expense in the accompanying consolidated statement of income. There was no expense related to interest rate derivative agreements for the three and six months ended June 30, 2016.

While Delek has not elected to apply permitted hedge accounting treatment for these interest rate derivatives in accordance with the provisions of ASC 815 in the past, we may choose to apply that treatment for future transactions.

Dividends

During the six months ended June 30, 2016, our Board of Directors declared the following dividends:

Date Declared	Dividend Amount Per Share	Record Date	Payment Date
February 25, 2016	$0.15	March 15, 2016	March 29, 2016
May 4, 2016	$0.15	May 24, 2016	June 14, 2016

Stock Repurchase Program

In February 2016, our Board of Directors authorized common stock repurchases in the aggregate amount of up to $125.0 million. Any repurchases may be implemented through open market transactions or in privately negotiated transactions, in accordance with applicable securities laws. The timing, price, and size of repurchases will be made at the discretion of management and will depend upon prevailing market prices, general economic and market conditions and other considerations. The stock repurchase authorization does not obligate us to acquire any particular amount of stock and any unused portion of the authorization will expire on December 31, 2016. During the three and six months ended June 30, 2016, 205,881 and 386,090 shares of our common stock were repurchased, for a total of $3.2 million and $6.0 million, respectively, under the stock repurchase authorization.

9. Income Taxes

Under ASC 740, Income Taxes (“ASC 740”), companies are required to apply an estimated annual tax rate to interim period results on a year-to-date basis; however, the estimated annual tax rate should not be applied to interim financial results if a reliable estimate cannot be made.  In this situation, the interim tax rate should be based on actual year-to-date results.  Based on our current projections, which have fluctuated as a result of changes in oil prices and the related crack spread, we believe that using actual year-to-date results to compute our effective tax rate will produce a more reliable estimate of our tax expense or benefit for the three and six months ended June 30, 2016.  As such, in contrast with our previous methods of recording income tax expense, we recorded a tax provision for the three and six months ended June 30, 2016 based on actual year-to-date results, in accordance with ASC 740.

15

Our effective tax rate was 93.8% and 58.2% for the three and six months ended June 30, 2016, respectively, compared to 21.5% and 17.0% for the three and six months ended June 30, 2015, respectively. The increase in our effective tax rate in the three and six months ended June 30, 2016 was primarily due to the change in methodology from using an estimated annual effective tax rate to an actual three and six month effective tax rate, as well as the benefit that we received from certain tax credits and other favorable permanent items impacting our quarterly results.

10. Equity-Based Compensation

Delek US Holdings, Inc. 2006 Long-Term Incentive Plan

Compensation expense for Delek equity-based awards amounted to $3.7 million ($2.4 million, net of taxes) and $7.4 million ($4.8 million, net of taxes) for the three and six months ended June 30, 2016, respectively, and $3.8 million ($2.5 million, net of taxes) and $7.0 million ($4.5 million, net of taxes) for the three and six months ended June 30, 2015, respectively. These amounts are included in general and administrative expenses in the accompanying condensed consolidated statements of income.

As of June 30, 2016, there was $29.7 million of total unrecognized compensation cost related to non-vested share-based compensation arrangements, which is expected to be recognized over a weighted-average period of 1.8 years.

We issued 32,166 and 72,632 shares of common stock as a result of exercised stock options, stock appreciation rights, and vested restricted stock units during the three and six months ended June 30, 2016, respectively, and 118,340 and 198,683 shares during the three and six months ended June 30, 2015, respectively. These amounts do not include shares withheld to satisfy employee tax obligations related to the exercises and vestings. Such withheld shares totaled 15,396 and 27,579 during the three and six months ended June 30, 2016, respectively, and 138,984 and 202,157 shares during the three and six months ended June 30, 2015, respectively.

Delek US Holdings, Inc. 2016 Long-Term Incentive Plan

On May 5, 2016, our stockholders approved our 2016 Long-Term Incentive Plan (the “2016 Plan”). The 2016 Plan succeeds our 2006 Long-Term Incentive Plan, which expired in April 2016. The 2016 Plan allows Delek to grant stock options, SARs, restricted stock, RSUs, performance awards and other stock-based awards of up to 4,400,000 shares of Delek's common stock to certain directors, officers, employees, consultants and other individuals who perform services for Delek or its affiliates.  Stock options and SARs issued under the 2016 Plan are granted at prices equal to (or greater than) the fair market value of Delek's common stock on the grant date and are generally subject to a vesting period of one year or more. No awards will be made under the 2016 Plan after May 5, 2026.

Delek Logistics GP, LLC 2012 Long-Term Incentive Plan

Compensation expense for Delek Logistics GP equity-based awards was $0.4 million ($0.3 million, net of taxes) and $0.8 million ($0.5 million, net of taxes) for the three and six months ended June 30, 2016, respectively, and $0.7 million ($0.5 million, net of taxes) and $1.1 million ($0.7 million, net of taxes) for the three and six months ended June 30, 2015, respectively. These amounts are included in general and administrative expenses in the accompanying condensed consolidated statements of income.

As of June 30, 2016, there was $2.7 million of total unrecognized compensation cost related to non-vested share-based compensation arrangements, which is expected to be recognized over a weighted-average period of 1.8 years.

11. Earnings (Loss) Per Share

Basic and diluted earnings per share are computed by dividing net income (loss) by the weighted average common shares outstanding. The common shares used to compute Delek’s basic and diluted earnings (loss) per share are as follows:

	Three Months Ended		Six Months Ended

12. Segment Data

We aggregate our operating units into three reportable segments: refining, logistics and retail. Our corporate activities, results of certain immaterial operating segments, our equity method investment in Alon USA and intercompany eliminations are reported in the corporate, other and eliminations segment. Decisions concerning the allocation of resources and assessment of operating performance are made based on this segmentation. Management measures the operating performance of each of the reportable segments based on the segment contribution margin.

Segment contribution margin is defined as net sales less cost of sales and operating expenses, excluding depreciation and amortization. Operations which are not specifically included in the reportable segments are included in the corporate and other category, which primarily consists of operating expenses, depreciation and amortization expense and interest income and expense associated with our corporate headquarters.

The refining segment processes crude oil and other purchased feedstocks for the manufacture of transportation motor fuels, including various grades of gasoline, diesel fuel, aviation fuel, asphalt and other petroleum-based products that are distributed through owned and third-party product terminals. The refining segment has a combined nameplate capacity of 155,000 bpd, including the 75,000 bpd Tyler refinery and the 80,000 bpd El Dorado refinery. The refining segment also owns and operates two biodiesel facilities involved in the production of biodiesel fuels and related activities.

Our logistics segment owns and operates crude oil and refined products logistics and marketing assets. The logistics segment generates revenue and subsequently contribution margin by charging fees for gathering, transporting and storing crude oil and for marketing, distributing, transporting and storing intermediate and refined products.

Our retail segment markets gasoline, diesel, other refined petroleum products and convenience merchandise through a network of company-operated retail fuel and convenience stores throughout the southeastern United States. As of June 30, 2016, we had 348 stores in total, consisting of 187 located in Tennessee, 89 in Alabama, 42 in Georgia, 12 in Arkansas, eight in Virginia, six in Kentucky and four in Mississippi. The retail fuel and convenience stores operate under Delek's MAPCO Express^®, MAPCO Mart^®, East Coast^®, Fast Food and Fuel^TM, Favorite Markets^®, Delta Express^® and Discount Food Mart^TM brands. The retail segment also supplied fuel to approximately 65 contracted dealer locations as of June 30, 2016. In the retail segment, management reviews operating results on a divisional basis, where a division represents a specific geographic market. These divisional operating segments exhibit similar economic characteristics, provide the same products and services, and operate in such a manner such that aggregation of these operations is appropriate for segment presentation.

Our refining segment has a services agreement with our logistics segment, which, among other things, requires the refining segment to pay service fees based on the number of gallons sold at the Tyler refinery and a sharing of a portion of the margin achieved in return for providing marketing, sales and customer services. This intercompany transaction fee was $4.2 million and $8.1 million during the three and six months ended June 30, 2016, respectively, and $3.8 million and $6.8 million during the three and six months ended June 30, 2015, respectively. Additionally, the refining segment pays crude transportation, terminalling and storage fees to the logistics segment for the utilization of pipeline, terminal and storage assets. These fees were $30.7 million and $61.7 million during the three and six months ended June 30, 2016, respectively, and $31.9 million and $59.5 million during the three and six months ended June 30, 2015, respectively. The logistics segment also sold $1.4 million and $2.9 million of Renewable Identification Numbers ("RINs") to the refining segment during the three and six months ended June 30, 2016, respectively, and $2.3 million and $3.9 million during the three and six months ended June 30, 2015, respectively. The refining segment

17

recorded sales and fee revenues from the retail and logistics segments in the amount of $97.1 million and $188.5 million during the three and six months ended June 30, 2016, respectively, and $188.9 million and $315.2 million during the three and six months ended June 30, 2015, respectively. All inter-segment transactions have been eliminated in consolidation.

In accordance with ASC 360, Property, Plant & Equipment, Delek evaluates the realizability of property, plant and equipment as events occur that might indicate potential impairment.

13. Fair Value Measurements

The fair values of financial instruments are estimated based upon current market conditions and quoted market prices for the same or similar instruments. Management estimates that the carrying value approximates fair value for all of Delek’s assets and liabilities that fall under the scope of ASC 825, Financial Instruments.

Delek applies the provisions of ASC 820, Fair Value Measurements ("ASC 820"), which defines fair value, establishes a framework for its measurement and expands disclosures about fair value measurements. ASC 820 applies to our interest rate and commodity derivatives that are measured at fair value on a recurring basis. The standard also requires that we assess the impact of nonperformance risk on our derivatives. Nonperformance risk is not considered material at this time.

ASC 820 requires disclosures that categorize assets and liabilities measured at fair value into one of three different levels depending on the observability of the inputs employed in the measurement. Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Level 2 inputs are observable inputs other than quoted prices included within Level 1 for the asset or liability, either directly or indirectly through market-corroborated inputs. Level 3 inputs are unobservable inputs for the asset or liability reflecting our assumptions about pricing by market participants.

Over the counter ("OTC") commodity swaps, physical commodity purchase and sale contracts and interest rate swaps and caps are generally valued using industry-standard models that consider various assumptions, including quoted forward prices, spot prices, interest rates, time value, volatility factors and contractual prices for the underlying instruments, as well as other relevant economic measures. The degree to which these inputs are observable in the forward markets determines the classification as Level 2 or 3. Our contracts are valued based on exchange pricing and/or price index developers such as Platts or Argus and are, therefore, classified as Level 2.

The U.S. Environmental Protection Agency ("EPA") requires certain refiners to blend biofuels into the fuel products they produce pursuant to the EPA’s Renewable Fuel Standard - 2.  Alternatively, credits called RINs, which may be generated and/or purchased, can be used to satisfy this obligation instead of physically blending biofuels ("RINs Obligation"). Our RINs Obligation surplus or deficit is based on the amount of RINs we must purchase, net of amounts internally generated and the price of those RINs as of the balance sheet date. The RINs Obligation surplus or deficit is categorized as Level 2 and is measured at fair value based on quoted prices from an independent pricing service.

20

The fair value hierarchy for our financial assets and liabilities accounted for at fair value on a recurring basis at June 30, 2016 and December 31, 2015, was as follows (in millions):

	As of June 30, 2016

Net liabilities	$	—	$	(61.4	)	$	—	$	(61.4	)

The derivative values above are based on analysis of each contract as the fundamental unit of account as required by ASC 820. Derivative assets and liabilities with the same counterparty are not netted where the legal right of offset exists. This differs from the presentation in the financial statements which reflects our policy under the guidance of ASC 815-10-45, wherein we have elected to offset the fair value amounts recognized for multiple derivative instruments executed with the same counterparty and where the legal right of offset exists. As of June 30, 2016 and December 31, 2015, $20.5 million and $23.9 million, respectively, of cash collateral was held by counterparty brokerage firms and has been netted with the net derivative positions with each counterparty.

14. Derivative Instruments

We use derivatives to reduce normal operating and market risks with the primary objective of reducing the impact of market price volatility on our results of operations. As such, our use of derivative contracts is aimed at:

• limiting the exposure to price fluctuations of commodity inventory above or below target levels at each of our segments;

• managing our exposure to commodity price risk associated with the purchase or sale of crude oil, feedstocks and finished grade fuel products at each of our segments; and

• limiting the exposure to interest rate fluctuations on our floating rate borrowings.

We primarily utilize OTC commodity swaps, generally with maturity dates of three years or less, and interest rate swap and cap agreements to achieve these objectives. OTC commodity swap contracts require cash settlement for the commodity based on the difference between a fixed or floating price and the market price on the settlement date. Interest rate swap and cap agreements economically hedge floating rate debt by exchanging interest rate cash flows, based on a notional amount from a floating rate to a fixed rate. At this time, we do not believe there is any material credit risk with respect to the counterparties to these contracts.

21

In accordance with ASC 815, certain of our OTC commodity swap contracts have been designated as cash flow hedges and the effective portion of the change in fair value between the execution date and the end of period has been recorded in other comprehensive income. The effective portion of the fair value of these contracts is recognized in income at the time the positions are closed and the hedged transactions are recognized in income.

From time to time, we also enter into futures contracts with supply vendors that secure supply of product to be purchased for use in the normal course of business at our refining and retail segments. These contracts are priced based on an index that is clearly and closely related to the product being purchased, contain no net settlement provisions and typically qualify under the normal purchase exemption from derivative accounting treatment under ASC 815.

The following table presents the fair value of our derivative instruments as of June 30, 2016 and December 31, 2015. The fair value amounts below are presented on a gross basis and do not reflect the netting of asset and liability positions permitted under our master netting arrangements, including cash collateral on deposit with our counterparties. We have elected to offset the recognized fair value amounts for multiple derivative instruments executed with the same counterparty in our financial statements. As a result, the asset and liability amounts below differ from the amounts presented in our condensed consolidated balance sheets (in millions):

⁽¹⁾  As of June 30, 2016 and December 31, 2015, we had open derivative positions representing 11,726,590 barrels and 6,413,150 barrels, respectively, of crude oil and refined petroleum products. Of these open positions, contracts representing 1,983,600 barrels and 3,324,400 barrels were designated as hedging instruments as of June 30, 2016 and December 31, 2015, respectively.

⁽²⁾  As of June 30, 2016 and December 31, 2015, $20.5 million and $23.9 million, respectively, of cash collateral held by counterparties has been netted with the derivatives with each counterparty.

Total (losses) gains on our commodity derivatives recorded in cost of goods sold on the condensed consolidated statements of income for the three and six months ended June 30, 2016 and 2015 are as follows (in millions):

	Three Months Ended June 30,						Six Months Ended June 30,

Total	$	(18.7	)	$	(15.3	)	$	(26.5	)	$	(7.0	)

We also recorded expenses representing cash settlements and changes in estimated fair value of our interest rate derivative agreements of $0.1 million and $0.2 million for the three and six months ended June 30, 2015, respectively. These amounts are included in interest expense in the accompanying consolidated statements of income. There were no interest rate derivative agreements in place as of June 30, 2016 and we recognized no expense related to interest rate derivative agreements for the three and six months ended June 30, 2016.

For cash flow hedges, no component of the derivative instruments’ gains or losses was excluded from the assessment of hedge effectiveness for the three and six months ended June 30, 2016 or 2015. As of June 30, 2016 and December 31, 2015, losses of $25.2 million and $39.7 million, respectively, on cash flow hedges, net of tax, primarily related to future purchases of crude oil and the associated sale of finished grade fuel, remained in accumulated other comprehensive income. Losses of $4.6 million and $9.4 million, net of tax, on settled contracts were reclassified into cost of sales during the three and six months ended June 30, 2016, respectively. (Losses) gains of $(3.5) million and $1.5 million, net of tax, on settled contracts were reclassified into cost of sales during the three and six months ended June 30, 2015, respectively. We estimate that $49.3 million of deferred losses will be reclassified into cost of sales over the next 12 months as a result of hedged transactions that are forecasted to occur. For the six months ended June 30, 2016 and June 30, 2015, there were no amounts reclassified from accumulated other comprehensive income into income as a result of the discontinuation of cash flow hedge accounting.

15. Commitments and Contingencies

Litigation

In the ordinary conduct of our business, we are from time to time subject to lawsuits, investigations and claims, including environmental claims and employee-related matters.

In 2013, we experienced a security breach by third-party hackers that may have compromised the credit/debit card information of certain of our retail segment customers. The incident involved credit/debit card payments for transactions at certain retail locations between March 19-25, 2013, April 14-15, 2013 and April 20-21, 2013, and several lawsuits have been brought against us as a result of this incident. Although we are unable to definitively determine the extent of any potential losses related to this breach, we do not believe that this incident will have a material adverse effect on our business, financial condition or results of operations.

Although we cannot predict with certainty the ultimate resolution of lawsuits, investigations and claims asserted against us, including civil penalties or other enforcement actions, we do not believe that any currently pending legal proceeding or proceedings to which we are a party will have a material adverse effect on our business, financial condition or results of operations.

Self-insurance

Delek is self-insured for workers’ compensation claims up to $1.0 million on a per-accident basis. We self-insure for general liability claims up to $4.0 million on a per-occurrence basis. We self-insure for auto liability up to $4.0 million on a per-accident basis.

We have umbrella liability insurance available to each of our segments in an amount determined reasonable by management.

23

Environmental, Health and Safety

We are subject to extensive federal, state and local environmental and safety laws and regulations enforced by various agencies, including the EPA, the United States Department of Transportation, the Occupational Safety and Health Administration, the Texas Commission on Environmental Quality, the Railroad Commission of Texas, the Arkansas Department of Environmental Quality (the "ADEQ") and the Tennessee Department of Environment and Conservation as well as other state and federal agencies. These laws and regulations govern the discharge of materials into the environment, waste management practices, pollution prevention measures and the composition of the fuels we produce, as well as the safe operation of our plants and pipelines and the safety of our workers and the public. Numerous permits or other authorizations are required under these laws and regulations for the operation of our refineries, biodiesel facilities, terminals, pipelines, underground storage tanks ("USTs"), trucks, rail cars and related operations, and may be subject to revocation, modification and renewal.

These laws and permits raise potential exposure to future claims and lawsuits involving environmental and safety matters which could include soil and water contamination, air pollution, personal injury and property damage allegedly caused by substances which we manufactured, handled, used, released or disposed of, transported, or that relate to pre-existing conditions for which we have assumed responsibility. We believe that our current operations are in substantial compliance with existing environmental and safety requirements. However, there have been and will continue to be ongoing discussions about environmental and safety matters between us and federal and state authorities, including notices of violations, citations and other enforcement actions, some of which have resulted or may result in changes to operating procedures and in capital expenditures. While it is often difficult to quantify future environmental or safety related expenditures, we anticipate that continuing capital investments and changes in operating procedures will be required for the foreseeable future to comply with existing and new requirements, as well as evolving interpretations and more strict enforcement of existing laws and regulations.

As of June 30, 2016, we have recorded an environmental liability of approximately $8.5 million, primarily related to the estimated probable costs of remediating or otherwise addressing certain environmental issues of a non-capital nature at the Tyler and El Dorado refineries. This liability includes estimated costs for ongoing investigation and remediation efforts, which were already being performed by the former operators of the Tyler and El Dorado refineries prior to our acquisition of those facilities, for known contamination of soil and groundwater, as well as estimated costs for additional issues which have been identified subsequent to the acquisitions. We expect approximately $0.4 million of this amount to be reimbursable by a prior owner of the El Dorado refinery and have recorded $0.4 million in other current assets in our condensed consolidated balance sheet as of June 30, 2016. Approximately $1.8 million of the total liability is expected to be expended over the next 12 months with most of the balance expended by 2022. In the future, we could be required to extend the expected remediation period or undertake additional investigations of our refineries, pipelines and terminal facilities or convenience stores, which could result in additional remediation liabilities.

We have experienced several crude oil releases from pipelines owned by our logistics segment, including, but not limited to, a release at Magnolia Station in March 2013, a release near Fouke, Arkansas in April 2015 and a release near Woodville, Texas in January 2016. In June 2015, the United States Department of Justice notified Delek Logistics that they were evaluating an enforcement action on behalf of the EPA with regard to potential Clean Water Act violations arising from the March 2013 Magnolia Station release. We are currently attempting to negotiate a resolution to this matter with the EPA and the ADEQ, which may include monetary penalties and/or other relief. Based on current information available to us, we do not believe the total costs associated with these events, whether alone or in the aggregate, including any fines or penalties, will have a material adverse effect upon our business, financial condition or results of operations.

Vendor Commitments

We maintain an agreement with a significant vendor that requires our retail segment to purchase certain general merchandise exclusively from this vendor over a specified period of time. Additionally, we maintain agreements with certain fuel suppliers that contain terms which generally require our retail segment to purchase predetermined quantities of third-party branded fuel for a specified period of time. In certain fuel vendor contracts, penalty provisions exist if our retail segment does not purchase certain minimum quantities of fuel.

Letters of Credit

As of June 30, 2016, we had in place letters of credit totaling approximately $104.6 million with various financial institutions securing obligations primarily with respect to our crude oil purchases for the refining segment, our gasoline and diesel purchases for the logistics segment and our workers’ compensation and general liability self-insurance programs. No amounts were drawn by beneficiaries of these letters of credit at June 30, 2016.

16. Subsequent Events

Dividend Declaration

On August 2, 2016, our Board of Directors voted to declare a quarterly cash dividend of $0.15 per share of our common stock, payable on September 13, 2016 to shareholders of record on August 23, 2016.

ITEM 2.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Management’s Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") is management’s analysis of our financial performance and of significant trends that may affect our future performance. The MD&A should be read in conjunction with our condensed consolidated financial statements and related notes included elsewhere in this Quarterly Report on Form 10-Q and in the Annual Report on Form 10-K filed with the Securities and Exchange Commission ("SEC") on February 29, 2016 (the "Annual Report on Form 10-K"). Those statements in the MD&A that are not historical in nature should be deemed forward-looking statements that are inherently uncertain. Unless the context otherwise requires, references to "Delek," "the Company," and "we," "our," or "us," and like terms refer to Delek US Holdings, Inc. and its consolidated subsidiaries.

Forward-Looking Statements

This Quarterly Report on Form 10-Q contains "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act").

Forward-looking statements include, among other things, the information concerning our possible future results of operations, business and growth strategies, financing plans, expectations that regulatory developments or other matters will or will not have a material adverse effect on our business or financial condition, our competitive position and the effects of competition, the projected growth of the industry in which we operate, and the benefits and synergies to be obtained from our completed and any future acquisitions, statements of management’s goals and objectives, and other similar expressions concerning matters that are not historical facts. Words such as "may," "will," "should," "could," "would," "predicts," "potential," "continue," "expects," "anticipates," "future," "intends," "plans," "believes," "estimates," "appears," "projects" and similar expressions, as well as statements in future tense, identify forward-looking statements.

Forward-looking statements should not be read as a guarantee of future performance or results, and will not necessarily be accurate indications of the times at, or by, which such performance or results will be achieved. Forward-looking information is based on information available at the time and/or management’s good faith belief with respect to future events, and is subject to risks and uncertainties that could cause actual performance or results to differ materially from those expressed in the statements. Important factors that, individually or in the aggregate, could cause such differences include, but are not limited to:

• volatility in our refining margins or fuel gross profit as a result of changes in the prices of crude oil, other feedstocks and refined petroleum products;

• our ability to execute our strategy of growth through acquisitions and the transactional risks inherent in such acquisitions;

• acquired assets may suffer a diminishment in fair value, which may require us to record a write-down or impairment;

• reliability of our operating assets;

• competition;

• changes in, or the failure to comply with, the extensive government regulations applicable to our industry segments;

• diminution in value of long-lived assets may result in an impairment in the carrying value of the asset on our balance sheet and a resultant loss recognized in the statement of operations;

• general economic and business conditions, particularly levels of spending relating to travel and tourism or conditions affecting the southeastern United States;

• volatility of derivative instruments;

• dependence on one wholesaler for a significant portion of our convenience store merchandise;

• deterioration of creditworthiness or overall financial condition of a material counterparty (or counterparties);

• unanticipated increases in cost or scope of, or significant delays in the completion of, our capital and periodic turnaround projects;

• risks and uncertainties with respect to the quantities and costs of refined petroleum products supplied to our pipelines and/or held in our terminals;

• operating hazards, natural disasters, casualty losses and other matters beyond our control;

In light of these risks, uncertainties and assumptions, our actual results of operations and execution of our business strategy could differ materially from those expressed in, or implied by, the forward-looking statements, and you should not place undue reliance upon them. In addition, past financial and/or operating performance is not necessarily a reliable indicator of future performance and you should not use our historical performance to anticipate future results or period trends. We can give no assurances that any of the events anticipated by any forward-looking statements will occur or, if any of them do, what impact they will have on our results of operations and financial condition.

Forward-looking statements speak only as of the date the statements are made. We assume no obligation to update forward-looking statements to reflect actual results, changes in assumptions or changes in other factors affecting forward-looking information except to the extent required by applicable securities laws. If we do update one or more forward-looking statements, no inference should be drawn that we will make additional updates with respect thereto or with respect to other forward-looking statements.

Executive Summary and Strategic Overview

Business Overview

We are an integrated downstream energy business focused on petroleum refining, the wholesale distribution of refined products and convenience store retailing. Our business consists of three operating segments: (1) refining, (2) logistics, and (3) retail. Our refining segment operates refineries in Tyler, Texas (the "Tyler refinery") and El Dorado, Arkansas (the "El Dorado refinery") with a combined design crude throughput capacity of 155,000 barrels per day ("bpd"). Our logistics segment gathers, transports and stores crude oil and markets, distributes, transports and stores refined products in select regions of the southeastern United States and west Texas for our refining segment and third parties. Our retail segment markets gasoline, diesel, other refined petroleum products and convenience merchandise through a network of 348 company-operated retail fuel and convenience stores located in Alabama, Arkansas, Georgia, Kentucky, Mississippi, Tennessee and Virginia.

We own a 59.7% limited partner interest in Delek Logistics Partners, LP ("Delek Logistics") and a 95.1% interest in the entity that owns the entire 2.0% general partner interest in Delek Logistics and all of the incentive distribution rights. Delek Logistics was formed by Delek in 2012 to own, operate, acquire and construct crude oil and refined products logistics and marketing assets. Delek Logistics' initial assets were contributed by us and included certain assets formerly owned or used by certain of our subsidiaries. A substantial majority of Delek Logistics' assets are currently integral to our refining and marketing operations.

Our profitability in the refining segment is substantially determined by the difference between the cost of the crude oil feedstocks we purchase and the price of the refined products we sell, referred to as the "crack spread", "refining margin" or "refined product margin." The cost to acquire feedstocks and the price of the refined petroleum products we ultimately sell from our refineries depend on numerous factors beyond our control, including the supply of, and demand for, crude oil, gasoline and other refined petroleum products which, in turn, depend on, among other factors, changes in domestic and foreign economies, weather conditions such as hurricanes or tornadoes, local, domestic and foreign political affairs, global conflict, production levels, the availability of imports, the marketing of competitive fuels and government regulation. Other significant factors that influence our results in the refining segment include operating costs (particularly the cost of natural gas used for fuel and the cost of electricity), seasonal factors, refinery utilization rates and planned or unplanned maintenance activities or turnarounds. Moreover, while the fluctuations in the cost of crude oil are typically reflected in the prices of light refined products, such as gasoline and diesel fuel, the price of other residual products, such as asphalt, coke, carbon black oil and liquefied petroleum gas ("LPG"), are less likely to move in parallel with crude cost. This could cause additional pressure on our realized margin during periods of rising or falling crude oil prices. Additionally, our margins are impacted by the pricing differentials of the various types and sources of crude oil we use at our two refineries and their relation to product pricing, such as the differentials between Midland West Texas Intermediate crude oil ("WTI") and Cushing WTI or Cushing WTI and Brent crude oil.

26

For our Tyler refinery, we compare our per barrel refined product margin to a well established industry metric: the U.S. Gulf Coast 5-3-2 crack spread ("Gulf Coast crack spread"). The Gulf Coast crack spread is used as a benchmark for measuring a refinery's product margins by measuring the difference between the market price of light products and crude oil. It represents the approximate gross margin resulting from processing one barrel of crude oil into three-fifths of a barrel of gasoline and two-fifths of a barrel of high-sulfur diesel. We calculate the Gulf Coast crack spread using the market value of U.S. Gulf Coast Pipeline CBOB and U.S. Gulf Coast Pipeline No. 2 Heating Oil (high sulfur diesel) and the first month futures price of WTI on the New York Mercantile Exchange ("NYMEX"). U.S. Gulf Coast CBOB is a grade of gasoline commonly blended with biofuels and marketed as Regular Unleaded at retail locations. U.S. Gulf Coast Pipeline No. 2 Heating Oil is a petroleum distillate that can be used as either a diesel fuel or a fuel oil. This is the standard by which other distillate products (such as ultra low sulfur diesel) are priced. The NYMEX is a commodities trading exchange where contracts for the future delivery of petroleum products are bought and sold.

The crude oil and product slate flexibility of the El Dorado refinery allows us to take advantage of changes in the crude oil and product markets; therefore, we anticipate that the quantities and varieties of crude oil processed and products manufactured at the El Dorado refinery will continue to vary. Thus, we do not believe that it is possible to develop a reasonable refined product margin benchmark that would accurately portray our refined product margins at the El Dorado refinery.

The cost to acquire the refined fuel products we sell to our wholesale customers in our logistics segment and to retail customers at our convenience stores in our retail segment depends on numerous factors beyond our control, including the supply of, and demand for, crude oil, gasoline and other refined petroleum products which, in turn, depend on, among other factors, changes in domestic and foreign economies, weather conditions, domestic and foreign political affairs, production levels, the availability of imports, the marketing of competitive fuels and government regulation. Our retail merchandise sales are driven by our ability to offer competitive prices on the products we offer, the accessibility of our convenience store locations, our ability to offer a high level of customer service and our ability to effectively promote our convenience brand in the regional markets we serve. Motor fuel margin is defined as gross sales less the delivered cost of fuel and motor fuel taxes and is measured on a cents per gallon basis. Our motor fuel margins are impacted by local supply, demand, weather, competitor pricing, blending of renewable fuels and product brand.

We also own a non-controlling equity interest of approximately 48% of the outstanding shares in Alon USA Energy, Inc. (NYSE: ALJ) ("Alon USA"). Alon USA is an independent refiner and marketer of petroleum products, operating primarily in the South Central, Southwestern and Western regions of the United States. Alon USA owns 100% of the general partner and 81.6% of the limited partner interests in Alon USA Partners, LP (NYSE: ALDW), which owns a crude oil refinery in Big Spring, Texas with a crude oil throughput capacity of 73,000 bpd and an integrated wholesale marketing business. In addition, Alon USA directly owns a crude oil refinery in Krotz Springs, Louisiana with a crude oil throughput capacity of 74,000 bpd. Alon USA also owns crude oil refineries in California, which have not processed crude oil since 2012. Alon USA is a leading marketer of asphalt, which they distribute primarily through asphalt terminals located predominately in the Southwestern and Western United States. Alon USA is the largest 7-Eleven licensee in the United States and operates approximately 300 convenience stores which market motor fuels in Central and West Texas and New Mexico. Our investment in Alon USA is accounted for as an equity method investment and the earnings from this equity method investment reflected in our consolidated statements of income include our share of net earnings directly attributable to this equity method investment, and amortization of the excess of our investment balance over the underlying net assets of Alon USA.

As of June 30, 2016, due to the decline in the quoted market price of Alon USA below the carrying amount of our investment, we evaluated our investment in Alon USA for potential impairment. We have determined that the decline in the market value of the ALJ Shares is not other than temporary and, therefore, it was not necessary to record an impairment charge on our investment at June 30, 2016. In determining whether the decline is other than temporary, we considered the cyclical nature of our industry, Alon USA's historical performance, its performance in relation to its peers and the current economic environment. However, future conditions in the industry, operating performance and performance in relation to peers and the future economic environment may vary from those informing our current assessment of recoverability. Such future conditions could therefore cause us to determine that a decline in fair value is other than temporary. If we later determine that the decline is other than temporary, we will record a write-down in the carrying value of our asset to the then-current fair market value.

As part of our overall business strategy, we regularly evaluate opportunities to expand our portfolio of businesses and may at any time be discussing or negotiating a transaction that, if consummated, could have a material effect on our business, financial condition, liquidity or results of operations.

Recent Developments

Return to Shareholders

Dividends

On June 14, 2016, we paid a regular dividend of $0.15 per share of our common stock, declared on May 4, 2016 to shareholders of record on May 24, 2016. On August 2, 2016, our Board of Directors voted to declare a quarterly cash dividend of $0.15 per share of our common stock, payable on September 13, 2016 to shareholders of record on August 23, 2016.

Share Repurchase Program

In February 2016, the Board of Directors authorized a share repurchase program for up to $125.0 million of our common stock. Any share repurchases under the repurchase program may be implemented through open market transactions or in privately negotiated transactions, in accordance with applicable securities laws. The timing, price, and size of repurchases will be made at the discretion of management and will depend on prevailing market prices, general economic and market conditions and other considerations. The repurchase program does not obligate us to acquire any particular amount of stock, and any unused portion of the authorization will expire on December 31, 2016. During the three and six months ended June 30, 2016, 205,881 and 386,090 shares of our common stock were repurchased, for a total of $3.2 million and $6.0 million, respectively, under the stock repurchase authorization.

Market Trends

Our results of operations are significantly affected by fluctuations in the prices of certain commodities, including, but not limited to, crude oil, gasoline, distillate fuel, biofuels and natural gas and electricity, among others. Historically, our profitability has been affected by commodity price volatility, specifically as it relates to the price of crude oil and refined products.

The table below reflects the quarterly high, low and average prices of Cushing WTI crude oil for each of the quarterly periods in 2015 and the quarterly periods during the six months ended June 30, 2016.

We continue to experience significant volatility in the energy markets. We believe that the fluctuation in the price of Cushing WTI crude oil in 2015 and the first six months of 2016 is primarily attributable to local and global oversupply, driven by an increase in domestic production and foreign exports. Fluctuations in the price of Cushing WTI crude oil impact the cost of raw materials processed at our refineries, as well as the price of finished products sold by all three of our operating segments.

28

The table below reflects the quarterly high, low and average 5-3-2 crack spread for each of the quarterly periods in 2015 and the quarterly periods during the six months ended June 30, 2016.

The average Gulf Coast 5-3-2 crack spread declined to $8.74 during the first six months of 2016 from $16.81 during the first six months of 2015. The wholesale price of refined products contributed to the decline in the Gulf Coast 5-3-2 crack spread in the six months ended June 30, 2016, with the U.S. Gulf Coast price of gasoline declining 23.1%, from an average of $1.70 per gallon in the first six months of 2015 to $1.21 per gallon in the first six months of 2016 and the U.S. Gulf Coast price of High Sulfur Diesel declining 30.4%, from an average of $1.62 per gallon in the first six months of 2015 to $1.06 per gallon in the first six months of 2016. The charts below illustrate the the price of U.S. Gulf Coast Gasoline and U.S. High Sulfur Diesel for each of the quarterly periods in 2015 and the quarterly periods during the six months ended June 30, 2016.

30

Our Tyler and El Dorado refineries both continue to have greater access to Midland WTI and Midland WTI-linked crude feedstocks compared to certain of our competitors. As new pipelines increased the ability to ship price-advantaged crude oil supplies to and from the mid-continent region, we have experienced a decline in certain crude oil price differentials favorable to us. As these price differentials decrease, so does our competitive advantage created by our access to WTI-linked crude oil. The chart below illustrates the differentials of both Brent crude oil and Midland WTI crude oil as compared to Cushing WTI crude oil for each of the quarterly periods in 2015 and the quarterly periods during the six months ended June 30, 2016.

31

Environmentalregulations continue to affect our margins in the form of the increasing cost of RINs. On a consolidated basis, we work to balance our RINs obligations in order to minimize the effect of RINs on our results. While we generate RINs in all three operating segments through our ethanol blending and biodiesel production, our refining segment needs to purchase additional RINs to satisfy its obligations. As a result, increases in the price of RINs adversely affected our results of operations. It is not possible at this time to predict with certainty what future volumes or costs may be, but given the increase in required volumes and the volatile price of RINs, the cost of purchasing sufficient RINs could have an adverse impact on our results of operations if we are unable to recover those costs in the price of our refined products. The chart below illustrates the volatile nature of the price for RINs for each of the quarterly periods in 2015 and the quarterly periods during the six months ended June 30, 2016.

Seasonality

Demand for gasoline, convenience merchandise and asphalt products is generally lower during the winter months due to seasonal decreases in motor vehicle traffic and road and home construction. Additionally, varying vapor pressure requirements between the summer and winter months tighten summer gasoline supply. As a result, our operating results are generally lower during the first and fourth quarters of the year.

Contractual Obligations

There have been no material changes to our contractual obligations and commercial commitments during the six months ended June 30, 2016, from those disclosed in our Annual Report on Form 10-K.

Critical Accounting Policies

The preparation of our consolidated 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. The SEC has defined critical accounting policies as those that are both most important to the portrayal of our financial condition and results of operations and require our most difficult, complex or subjective judgments or estimates. Based on this definition and as further described in our Annual Report on Form 10-K, we believe our critical accounting policies include the following: (i) determining our inventory using the last-in, first-out valuation method, (ii) evaluating impairment for property, plant and equipment and definite life intangibles, (iii) valuing goodwill and potential impairment, and (iv) estimating environmental expenditures. For all financial statement periods presented, there have been no material modifications to the application of these critical accounting policies or estimates since our most recently filed Annual Report on Form 10-K.

Results of Operations

Consolidated Results of Operations — Comparison of the Three Months EndedJune 30, 2016 versus the Three Months EndedJune 30, 2015

Net Income

Consolidated net loss for the second quarter of 2016 was $7.0 million, or $0.11 per basic share, compared to net income of $48.3 million, or $0.79 per basic share, for the second quarter of 2015.

Net Sales

In the second quarters of 2016 and 2015, we generated net sales of $1,426.4 million and $1,693.1 million, respectively, a decrease of $266.7 million, or 15.8%. The decrease in net sales was primarily due to the effects of decreases in the price of finished petroleum products on all three operating segments in the second quarter of 2016, compared to the same period in 2015 and a decline in sales volumes at the El Dorado refinery, resulting from lower throughputs and production as operations matched commercial demand. These decreases were partially offset by an increase in merchandise sales in the retail segment.

Cost of Goods Sold

Cost of goods sold was $1,253.9 million for the second quarter of 2016 compared to $1,438.2 million for the second quarter of 2015, a decrease of $184.3 million, or 12.8%. The decrease in cost of goods sold primarily resulted from the decrease in the cost of both crude oil feedstocks in the refining segment and refined products in both the retail and logistics segments, partially offset by net RINs costs of $10.9 million for the second quarter of 2016, as compared to $0.5 million for the second quarter of 2015.

Operating Expenses

Operating expenses were $90.3 million for the second quarter of 2016 compared to $106.0 million for the second quarter of 2015, a decrease of $15.7 million, or 14.8%. The decrease in operating expenses was primarily due to decreases in spill remediation and utilities expense in the refining segment, decreases in maintenance expenses in the logistics segment and decreases in insurance and credit card expenses in our retail segment.

General and Administrative Expenses

General and administrative expenses were $29.3 million and $34.3 million for the second quarter of 2016 and 2015, respectively, a decrease of $5.0 million, or 14.6%. The decrease in general and administrative expenses was primarily due to a decrease in employee compensation related expenses. We do not allocate general and administrative expenses to our operating segments.

Depreciation and Amortization

Depreciation and amortization was $37.3 million for the second quarter of 2016 compared to $34.9 million for the second quarter

of 2015, an increase of $2.4 million, or 6.9%. The increase in depreciation expense was primarily attributable to the turnaround and expansion of the Tyler refinery completed in the first quarter of 2015, as well as capital expenditures and acquisitions completed in 2015.

Interest Expense

Interest expense was $15.4 million for the second quarter of 2016 compared to $17.3 million for the second quarter of 2015, a decrease of $1.9 million, or 11.0%. The decrease was primarily attributable to $3.9 million in one-time fees associated with the amendment of the Lion Term Loan in the second quarter of 2015, partially offset by interest costs associated with increased debt levels in the second quarter of 2016, related to the investment in Alon USA, compared to the same period in 2015.

Results from Equity Method Investments

During the second quarter of 2016, we recognized a loss from equity method investments of $10.6 million, compared to income from equity method investments of $7.4 million for the second quarter of 2015. Results from equity method investments for the second quarters of 2016 and 2015 was primarily attributable to our proportionate share of the net (loss) income from our investment in Alon USA of $(9.7) million and $9.2 million, respectively and $(0.7) million and $(1.7) million, respectively, in amortization of the excess of our investment over our equity in the underlying net assets of Alon USA.

Income Taxes

Under ASC 740, Income Taxes (“ASC 740”), companies are required to apply an estimated annual tax rate to interim period results on a year-to-date basis; however, the  estimated annual tax rate should not be applied to interim financial results if a reliable estimate cannot be made.  In this situation, the interim tax rate should be based on actual year-to-date results.  Based on our current projections, which have fluctuated as a result of changes in oil prices and related crack spread, we believe that using actual year-to-date results to compute our effective tax rate will produce a more reliable estimate of our tax expense for the three months ended June 30, 2016.  As such, in contrast with our previous methods of recording income tax expense, we recorded a tax provision for the three months ended June 30, 2016 based on actual year-to-date results, in accordance with ASC 740.

Income tax benefit was $9.0 million for the second quarter of 2016, compared to expense of $15.1 million for the second quarter of 2015, an increase in benefit of $24.1 million. The increase in benefit was primarily attributable to a pre-tax loss of $9.6 million in the second quarter of 2016, as compared to pre-tax income of $70.2 million for the second quarter of 2015. Our effective tax rate was 93.8% for the second quarter of 2016, compared to 21.5% for the second quarter of 2015. The increase in our effective tax rate in the second quarter of 2016 was primarily due to the change in methodology from using an estimated annual effective tax rate to an actual three month effective tax rate, as well as the benefit that we received from certain tax credits and other favorable permanent items impacting our quarterly results.

Consolidated Results of Operations — Comparison of the Six Months EndedJune 30, 2016 versus the Six Months EndedJune 30, 2015

Net Income

Consolidated net loss for the six months ended June 30, 2016 was $36.2 million, or $0.58 per basic share, compared to net income of $32.2 million, or $0.54 per basic share, for the six months ended June 30, 2015.

Net Sales

For the six months ended June 30, 2016 and 2015, we generated net sales of $2,532.3 million and $2,843.7 million, respectively, a decrease of $311.4 million, or 11.0%. The decrease in net sales was primarily due to the effects of decreases in the price of finished petroleum products on all three operating segments in the six months ended June 30, 2016, compared to the same period in 2015. These decreases were partially offset by an increase in sales volumes at the Tyler refinery, which was attributable to the lower volumes in the first quarter of 2015 due to downtime at the Tyler refinery for a turnaround and expansion project. Further offsetting the decrease was an increase in fuel volumes and merchandise sales in the retail segment.

Cost of Goods Sold

Cost of goods sold was $2,245.0 million for the six months ended June 30, 2016, compared to $2,444.3 million for the six months ended June 30, 2015, a decrease of $199.3 million, or 8.2%. The decrease in cost of goods sold primarily resulted from the decrease in the cost of both crude oil feedstocks in the refining segment and refined products in both the retail and logistics segments, partially offset by an increase in sales volumes at the Tyler refinery, net RINs costs of $19.4 million for the six months ended June 30, 2016, as compared to $0.4 million for the six months ended June 30, 2015 and losses associated with our hedging program of $26.5 million for the six months ended June 30, 2016, compared to losses of $7.0 million for the six months ended June 30, 2015.

Operating Expenses

Operating expenses were $192.2 million for the six months ended June 30, 2016 compared to $197.4 million for the six months ended June 30, 2015, a decrease of $5.2 million, or 2.6%. The decrease in operating expenses was primarily due to decreases in outside services, insurance and utilities expenses in the refining segment, maintenance expenses in the logistics segment and insurance, credit card and maintenance expenses in the retail segment. These decreases were partially offset by a full quarter of operating expenses at the Tyler refinery for the six months ended June 30, 2016 as compared to reduced expenses resulting from the downtime associated with the turnaround and expansion project during the first quarter of 2015, increased expenses associated with an internal tank contamination at one of our terminal locations in the logistics segment and an increase in salaries and lease expense in the retail segment.

Insurance proceeds — business interruption

We recognized proceeds from business interruption insurance claims of $42.4 million for the six months ended June 30, 2016, associated with a litigation settlement. We did not record any insurance proceeds for the six months ended June 30, 2015.

General and Administrative Expenses

General and administrative expenses were $63.9 million and $67.0 million for the six months ended June 30, 2016 and 2015, respectively, a decrease of $3.1 million, or 4.6%. The decrease in general and administrative expenses was primarily due to a decrease in employee compensation related expenses, partially offset by an increase in outside services associated with various marketing and procurement projects during the six months ended June 30, 2016, as compared to the same period of 2015. We do not allocate general and administrative expenses to our operating segments.

Depreciation and Amortization

Depreciation and amortization was $73.4 million for the six months ended June 30, 2016 compared to $63.2 million for the six months ended June 30, 2015, an increase of $10.2 million, or 16.1%. The increase in depreciation expense was primarily attributable to the turnaround and expansion of the Tyler refinery completed in the first quarter of 2015, as well as capital expenditures and acquisitions completed in 2015.

Interest Expense

Interest expense was $30.4 million for the six months ended June 30, 2016 compared to $27.4 million for the six months ended June 30, 2015, an increase of $3.0 million, or 10.9%. The increase was primarily attributable to interest costs associated with increased debt levels related to the investment in Alon USA. The increase was partially offset by $3.9 million in one-time fees associated with the amendment of the Lion Term Loan in the second quarter of 2015.

Results from Equity Method Investments

During the six months ended June 30, 2016, we recognized a loss from equity method investments of $28.6 million, compared to income of $7.4 million for the six months ended June 30, 2015, Results from equity method investments for the six months ended June 30, 2016 and 2015 are primarily attributable to our proportionate share of the net (loss) income from our investment in Alon USA of $(26.8) million and $9.2 million, respectively, and $(1.4) million and $(1.7) million in amortization of the excess of our investment over our equity in the underlying net assets of Alon USA.

Income Taxes

Under ASC 740, Income Taxes (“ASC 740”), companies are required to apply an estimated annual tax rate to interim period results on a year-to-date basis; however, the  estimated annual tax rate should not be applied to interim financial results if a reliable estimate cannot be made.  In this situation, the interim tax rate should be based on actual year-to-date results.  Based on our

35

current projections, which have fluctuated as a result of changes in oil prices and related crack spread, we believe that using actual year-to-date results to compute our effective tax rate will produce a more reliable estimate of our tax expense for the six months ended June 30, 2016.  As such, in contrast with our previous methods of recording income tax expense, we recorded a tax provision for the six months ended June 30, 2016 based on actual year-to-date results, in accordance with ASC 740.

Income tax benefit was $34.1 million for the six months ended June 30, 2016, compared to income tax expense of $9.1 million for the six months ended June 30, 2015, an increase of $43.2 million. The increase was primarily attributable to a pre-tax loss of $58.6 million for the six months ended June 30, 2016, compared to pre-tax income of $53.5 million for the six months ended June 30, 2015. Our effective tax rate was 58.2% for the six months ended June 30, 2016, compared to 17.0% for the six months ended June 30, 2015. The increase in our effective tax rate for the six months ended June 30, 2016 was primarily due to the change in methodology from using an estimated annual effective tax rate to an actual quarterly effective tax rate, as well as the benefit that we received from certain tax credits and other favorable permanent items impacting our quarterly results.

Operating Segments

We report operating results in three reportable segments: refining, logistics and retail. Decisions concerning the allocation of resources and assessment of operating performance are made based on this segmentation. Management measures the operating performance of each of its reportable segments based on the segment contribution margin.

Refining Segment Operational Comparison of the Three Months EndedJune 30, 2016 versus the Three Months EndedJune 30, 2015

Net Sales

Net sales for the refining segment were $1,077.7 million for the second quarter of 2016 compared to $1,336.8 million for the second quarter of 2015, a decrease of $259.1 million, or 19.4%. The decrease in net sales primarily resulted from declines in the price of U.S. Gulf Coast gasoline and Ultra-Low-Sulfur diesel ("ULSD") in the second quarter of 2016 as compared to the second quarter of 2015, as well as a decline in sales volumes at the El Dorado refinery resulting from lower throughputs and production as operations matched commercial demand.

Cost of Goods Sold

Cost of goods sold for the second quarter of 2016 for the refining segment was $988.1 million compared to $1,164.8 million for the second quarter of 2015, a decrease of $176.7 million, or 15.2%. This decrease was primarily attributable to a decrease in the cost of WTI crude oil, from an average of $57.80 per barrel in the second quarter of 2015 to an average of $45.56 in the second quarter of 2016, and a decrease in sales volumes at the El Dorado refinery.

These decreases were partially offset by an increase in the cost of RINs.

Our refining segment has multiple service agreements with our logistics segment which, among other things, require the refining segment to pay terminalling and storage fees based on the throughput volume of crude and finished product in the logistics segment pipelines and the volume of crude and finished product stored in the logistics segment storage tanks. These fees were $30.7 million and $31.9 million during the second quarters of 2016 and 2015, respectively. We eliminate these intercompany fees in consolidation.

Operating Expenses

Operating expenses for the refining segment were $49.6 million for the second quarter of 2016 compared to $60.0 million for the second quarter of 2015, a decrease of $10.4 million, or 17.3%. The decrease in operating expenses was primarily due to a decrease in oil spill remediation costs and a decrease in utilities expenses, primarily due to a reduction in natural gas prices and consumption, as well as certain cost reduction initiatives at both refineries.

Contribution Margin

Contribution margin for the refining segment decreased to $40.0 million, or 48.7% of our consolidated segment contribution margin, in the second quarter of 2016, compared to $112.0 million, or 75.2% of our consolidated segment contribution margin, in the second quarter of 2015. The refining segment contribution margin decrease was primarily attributable to a decline in gross margins at both the Tyler and El Dorado refineries, partially offset by a decline in operating expenses at both refineries.

38

Margins at both refineries were negatively impacted by a 47% decline in the average Gulf Coast 5-3-2 crack spread and a 70.0% decline in the average differential between WTI Midland crude oil and WTI Cushing crude oil in the second quarter of 2016 compared to the second quarter of 2015. Further contributing to the decline in margins were increases in RINs costs, to $12.3 million in the second quarter of 2016, compared to $2.4 million in the second quarter of 2015. These decreases were partially offset by a contango futures market in both the first quarters of 2016 and 2015, which lowered crude purchase prices by $1.43 per barrel in the second quarter of 2016, compared to $1.77 per barrel in the second quarter of 2015.

Refining Segment Operational Comparison of the Six Months EndedJune 30, 2016 versus the Six Months EndedJune 30, 2015

Net Sales

Net sales for the refining segment were $1,905.0 million for the six months ended June 30, 2016 compared to $2,163.8 million for the six months ended June 30, 2015, a decrease of $258.8 million, or 12.0%. The decrease in net sales resulted from declines in the price of U.S. Gulf Coast gasoline and Ultra-Low-Sulfur diesel ("ULSD") in the six months ended June 30, 2016 as compared to

the six months ended June 30, 2015. These decreases were partially offset by an increase in sales volumes at the Tyler refinery.

Cost of Goods Sold

Cost of goods sold for the refining segment for the six months ended June 30, 2016 was $1,776.0 million, compared to $1,921.7 million for the six months ended June 30, 2015, a decrease of $145.7 million, or 7.6%. This decrease was primarily attributable to a decrease in the cost of WTI crude oil, from an average of $53.33 per barrel for the six months ended June 30, 2015 to an average of $39.65 for the six months ended June 30, 2016. The decrease in crude oil prices was partially offset by the increase in sales volumes at the Tyler refinery resulting from the lower volumes in the first half of 2015 due to downtime at the Tyler refinery related to the turnaround and expansion project completed in the first quarter of 2015, an increase in the cost of RINs, and losses on derivative positions of $25.0 million for the six months ended June 30, 2016, compared to losses of $7.2 million for the six months ended June 30, 2015.

Our refining segment has multiple service agreements with our logistics segment which, among other things, require the refining segment to pay terminalling and storage fees based on the throughput volume of crude and finished product in the logistics segment pipelines and the volume of crude and finished product stored in the logistics segment storage tanks. These fees were $61.7 million and $59.5 million during the six months ended June 30, 2016 and 2015, respectively. We eliminate these intercompany fees in consolidation.

Operating Expenses

Operating expenses for the refining segment were $107.9 million for the six months ended June 30, 2016 compared to $108.2 million for the six months ended June 30, 2015, a decrease of $0.3 million, or 0.3%. The decrease in operating expenses was primarily due to a decrease in insurance expenses and utilities expenses, primarily due to a reduction in natural gas prices and consumption, as well as certain cost reduction initiatives at both refineries. These were partially offset by a full period of operating expenses at the Tyler refinery for the six months ended June 30, 2016, as compared to

39

reduced expenses resulting from downtime associated with the turnaround and expansion project completed in the first quarter of 2015.

Contribution Margin

Contribution margin for the refining segment decreased to $63.5 million, or 46.2% of our consolidated segment contribution margin, in the six months ended June 30, 2016, compared to $133.9 million, or 66.3% of our consolidated segment contribution margin, in the six months ended June 30, 2015. The refining segment contribution margin decrease was primarily attributable to a decline in operating margins at both refineries, which were partially offset by business interruption insurance proceeds of $42.4 million associated with a settlement of litigation received in the first quarter of 2016, as well as an increase in sales volumes at the Tyler refinery in the first half of 2016 attributable to the lower volumes in the same period of 2015 due to downtime at the Tyler refinery related to the turnaround and expansion project completed in the first quarter of 2015.

Margins at both refineries were negatively impacted by the decline in the average differential between WTI Midland crude oil and WTI Cushing crude oil and a decline in the Gulf Coast 5-3-2 crack spread. Further contributing to the decline in margins were losses on derivative positions of $25.0 million for the six months ended June 30, 2016, compared to losses of $7.2 million for the six months ended June 30, 2015 and an increase in RINs costs, to $22.5 million for the six months ended June 30, 2016, compared to $4.3 million for the six months ended June 30, 2015. These decreases were partially offset by a contango futures market in both the six months ended June 30, 2016 and 2015, which lowered crude purchase prices by $1.62 per barrel in the six months ended June 30, 2016, compared to $1.23 per barrel during the six months ended June 30, 2015.

Logistics Segment Operational Comparison of the Three Months EndedJune 30, 2016 versus the Three Months EndedJune 30, 2015

Net Sales

Net sales for the logistics segment were $111.8 million in the second quarter of 2016, compared to $172.1 million for the second quarter of 2015, a decrease of $60.3 million, or 35.0%. The decrease was primarily attributable to decreases in the average sales prices per gallon of gasoline and diesel and in diesel volumes sold in our west Texas marketing operations. Further contributing to the decrease were declines in fuel surcharge revenues and fees on our Paline Pipeline System. Partially offsetting the decreases were increased throughput at most of our terminals, including our terminals in El Dorado, Arkansas and Tyler, Texas.

Net sales included $4.2 million and $3.8 million of net service fees paid by our refining segment to our logistics segment during the second quarter of 2016 and 2015, respectively. These service fees are based on the number of gallons sold and a shared portion of the margin achieved in return for providing sales and customer support services. Net sales also included crude and refined product transportation, terminalling and storage fees paid by our refining segment to our logistics segment. These fees were $30.7 million and $31.9 million in the second quarter of 2016 and 2015, respectively. The logistics segment also sold $1.4 million and $2.3 million of RINs to the refining segment in the second quarter of 2016 and 2015, respectively. These intercompany sales and fees are eliminated in consolidation.

41

Cost of Goods Sold

Cost of goods sold for the logistics segment decreased $59.4 million, or 44.8%, to $73.1 million in the second quarter of 2016, compared to $132.5 million in the second quarter of 2015. The decrease in cost of goods sold was primarily attributable to decreases in average cost per gallon of gasoline and diesel and in diesel volumes purchased in our west Texas marketing operations. The average cost per gallon of gasoline decreased $0.46 during the second quarter of 2016 compared to the second quarter of 2015, while the average cost per gallon of diesel decreased $0.51 during the second quarter of 2016 compared to the second quarter of 2015.

Operating Expenses

Operating expenses for the logistics segment were approximately $8.7 million and $10.8 million for the second quarter of 2016 and 2015, respectively, a decrease of $2.1 million, or 19.4%. The decrease in operating expenses was primarily due to decreases in maintenance costs as a result of the completion of maintenance projects at our tank farms, the East Texas Crude Logistics System, the SALA Gathering System and two of our terminals in the west Texas area. Further contributing to the decrease were decreases in insurance expense related to our trucking assets and one of our terminals and reduced expenses associated with the El Dorado offloading rack assets. Partially offsetting these decreases were increases in costs associated with the operation of our trucking assets.

Contribution Margin

Contribution margin for the logistics segment increased to $30.0 million, or 36.5% of our consolidated segment contribution margin, in the second quarter of 2016, compared to $28.8 million, or 19.3% of our consolidated segment contribution margin, in the second quarter of 2015. The increase in contribution margin was attributable to increased throughput at most of our terminals, including our terminals in El Dorado, Arkansas and Tyler, Texas, and higher margins in our west Texas operations. Higher margins in our west Texas operations were achieved as a result of a more favorable supply/demand balance due to a third-party pipeline outage in the region in late May and early June 2016, compared to the second

quarter of 2015. Also contributing to the increase were reduced operating expenses.

Logistics Segment Operational Comparison of the Six Months EndedJune 30, 2016 versus the Six Months EndedJune 30, 2015

Net Sales

Net sales for the logistics segment were $215.9 million during the six months ended June 30, 2016, compared to $315.6 million during the six months ended June 30, 2015, a decrease of $99.7 million, or 31.6%. The decrease was primarily attributable to decreases in the average sales prices per gallon of gasoline and diesel and in diesel volumes sold in our west Texas marketing operations. Partially offsetting the decreases were increased throughput at most of our terminals, including our terminals in El Dorado, Arkansas and Tyler, Texas, increased fees and lower pipeline allowance losses on our Paline Pipeline System, and the effects of the throughput and tankage agreements with the refining segment, pursuant to which the logistics segment generated revenue on assets acquired from the refining segment during the six months ended June 30, 2016, with no comparable revenue earned during the six months ended June 30, 2015. Volumes and fees increased primarily as a result of the turnaround that occurred at the Tyler Refinery in the second quarter of 2015, during which the refinery was not fully operational. Offsetting the increases were decreases in fuel surcharge revenues associated with our trucking assets.

Net sales included $8.1 million and $6.8 million of net service fees paid by our refining segment to our logistics segment during the six months ended June 30, 2016 and 2015, respectively. These service fees are based on the number of gallons sold and a shared portion of the margin achieved in return for providing sales and customer support services. Net sales also included crude and refined product transportation, terminalling and storage fees paid by our refining segment to our logistics segment. These fees were $61.7 million and $59.5 million in the six months ended June 30, 2016 and 2015, respectively. The logistics segment also sold $2.9 million and $3.9 million of RINs to the refining segment in the six months ended June 30, 2016 and 2015, respectively. These intercompany sales and fees are eliminated in consolidation.

42

Cost of Goods Sold

Cost of goods sold for the logistics segment decreased $101.0 million, or 41.9%, to $139.9 million in the six months ended June 30, 2016, compared to $240.9 million in the six months ended June 30, 2015. The decrease in cost of goods sold was primarily attributable to decreases in average cost per gallon of gasoline and diesel and in diesel volumes purchased in our west Texas marketing operations. The average cost per gallon of gasoline decreased $0.47 during the six months ended June 30, 2016 compared to the six months ended June 30, 2015, while the average cost per gallon of diesel decreased $0.57 during the six months ended June 30, 2016 compared to the six months ended June 30, 2015.

Operating Expenses

Operating expenses for the logistics segment were approximately $19.2 million and $21.6 million for the six months ended June 30, 2016 and 2015, respectively, a decrease of $2.4 million, or 11.1%. The decrease in operating expenses was primarily due to decreases in maintenance costs as a result of the completion of maintenance projects at our tank farms, the East Texas Crude Logistics System, the SALA Gathering System and two of our terminals in the west Texas area. Partially offsetting these decreases were increases in costs associated with the operation and maintenance of our storage tanks at the El Dorado refinery and an increase in operating expense for one of our terminal locations related to internal tank contamination.

Contribution Margin

Contribution margin for the logistics segment increased to $56.8 million, or 41.3% of our consolidated segment contribution margin, for the six months ended June 30, 2016, compared to $53.1 million, or 26.3% of our consolidated segment contribution margin, for the six months ended June 30, 2015. The increase in contribution margin was primarily attributable to the increases in net sales discussed above, as well as the decreases in cost of sales and operating expenses, also described above. These increases were partially offset by a decline in margins in our west Texas operations.

Retail Segment

The table below sets forth certain information concerning our retail segment operations ($ in millions, except per gallon amounts):

Retail Segment Operational Comparison of the Three Months EndedJune 30, 2016 versus the Three Months EndedJune 30, 2015

Net Sales

43

Net sales for the retail segment in the second quarter of 2016 decreased $40.1 million, or 9.8%, to $369.8 million from $409.9 million in the second quarter of 2015. The decrease in net sales was primarily due to a decrease in the retail fuel price per gallon. The decrease in retail fuel prices was partially offset by an increase in merchandise sales in the second quarter of 2016, as compared with the same period in 2015.

Retail fuel gallons sold for the retail segment were 115.3 million gallons for the second quarter of 2016, compared to 116.2 million gallons for the second quarter of 2015. Same-store retail fuel gallons sold decreased 2.4% for the second quarter of 2016, compared to the second quarter of 2015. Total fuel sales, including wholesale dollars, decreased 13.9% to $258.8 million in the second quarter of 2016, compared to $300.7 million in the second quarter of 2015. The reduction in retail fuel sales volume is primarily due to pricing programs in the second quarter of 2016 focused on improving margin.

Merchandise sales for the retail segment increased 1.7% to $111.0 million in the second quarter of 2016, compared to $109.2 million in the second quarter of 2015. Same-store merchandise sales increased 1.7%, primarily due to increases in the cigarette and cold fountain beverage categories, partially offset by a decline in the bottled soft drinks category during the second quarter of 2016 as compared to the same period in 2015.

Cost of Goods Sold

Cost of goods sold for the retail segment decreased $41.5 million, or 11.5%, to $318.5 million in the second quarter of 2016 from $360.0 million in the second quarter of 2015. This decrease was primarily due to a decrease in the average retail fuel cost per gallon.

Operating Expenses

Operating expenses for the retail segment were $33.1 million in the second quarter of 2016 as compared to $35.6 million in the second quarter of 2015, a decrease of $2.5 million, or 7.0%. This decrease was primarily attributable to declines in insurance and credit expenses in the second quarter of 2016 as compared to the second quarter of 2015.

Contribution Margin

Contribution margin for the retail segment increased to $18.2 million, or 22.1% of our consolidated segment contribution margin, in the second quarter of 2016, compared to $14.3 million, or 9.6% of our consolidated segment contribution margin, in the second quarter of 2015. The increase was primarily due to increases in retail fuel margins and merchandise sales, as well as a decline in operating expenses in the second quarter of 2016, as compared to the second quarter of 2015.

Retail Segment Operational Comparison of the Six Months EndedJune 30, 2016 versus the Six Months EndedJune 30, 2015

Net Sales

44

Net sales for the retail segment in the six months ended June 30, 2016 decreased $76.5 million, or 10.2%, to $671.4 million from $747.9 million in the six months ended June 30, 2015. The decrease in net sales was primarily due to a decrease in the retail fuel price per gallon. The decrease in retail fuel prices was partially offset by an increase in fuel sales volumes and merchandise sales in the six months ended June 30, 2016, as compared with the same period in 2015.

Retail fuel gallons sold for the retail segment were 226.5 million gallons for the six months ended June 30, 2016, compared to 224.8 million gallons for the six months ended June 30, 2015. Same-store retail fuel gallons sold decreased 1.0% for the six months ended June 30, 2016, compared to the six months ended June 30, 2015. Total fuel sales, including wholesale dollars, decreased 15.3% to $460.9 million in the six months ended June 30, 2016, compared to $544.1 million in the six months ended June 30, 2015.

Merchandise sales for the retail segment increased 3.3% to $210.4 million in the six months ended June 30, 2016, compared to $203.8 million in the six months ended June 30, 2015. Same-store merchandise sales increased 3.2%, primarily due to increases in the cigarette and food service categories, partially offset by a decline in the soft drinks category during the six months ended June 30, 2016 as compared to the same period in 2015.

Cost of Goods Sold

Cost of goods sold for the retail segment decreased $78.5 million, or 12.0%, to $574.7 million in the six months ended June 30, 2016 from $653.2 million in the six months ended June 30, 2015. This decrease was primarily due to a decrease in the average retail fuel cost per gallon, partially offset by an increase in fuel sales volumes.

Operating Expenses

Operating expenses for the retail segment were $66.5 million in the six months ended June 30, 2016 as compared to $68.1 million in the six months ended June 30, 2015, a decrease of $1.6 million, or 2.3%. This decrease was primarily attributable to a decrease in insurance, credit and maintenance expenses, partially offset by an

increase in salaries and lease expenses in the six months ended June 30, 2016 as compared to the six months ended June 30, 2015.

Contribution Margin

Contribution margin for the retail segment increased to $30.2 million, or 22.0% of our consolidated segment contribution margin, in the six months ended June 30, 2016, compared to $26.6 million, or 13.2% of our consolidated segment contribution margin, in the six months ended June 30, 2015. The increase was primarily due to an increase in merchandise sales and retail fuel margins, as well as a decline in operating expenses in the six months ended June 30, 2016, as compared to the six months ended June 30, 2015.

Liquidity and Capital Resources

Our primary sources of liquidity are cash generated from our operating activities and borrowings under our credit facilities. We believe that our cash flows from operations and borrowings under or refinancings of our current credit facilities will be sufficient to satisfy the anticipated cash requirements associated with our existing operations and capital expenditures for at least the next 12 months.

Cash Flows

The following table sets forth a summary of our consolidated cash flows for the six months ended June 30, 2016 and 2015 (in millions):

	Six Months Ended June 30,
	2016			2015
Cash Flow Data:
Operating activities	$	156.6		$	73.7
Investing activities	(59.4		)	(344.2		)
Financing activities	(22.3		)	204.8
Net increase (decrease)	$	74.9		$	(65.7	)

Cash Flows from Operating Activities

Net cash provided by operating activities was $156.6 million for the six months ended June 30, 2016, compared to $73.7 million for the comparable period of 2015. The increase in cash flows from operations was primarily due to changes in working capital due to the full quarter of operations at the Tyler refinery in the first six months of 2016, as compared to the downtime in the first quarter of 2015 associated with the turnaround and expansion of the Tyler refinery, as well as a decrease in receivables, primarily related to the collection of $87.6 million of prior period tax related receivables in the first six months of 2016. These increases were partially offset by the net loss for the six months ended June 30, 2016 of $24.5 million, compared to net income of $44.4 million in the same period of 2015. The net loss for the six months ended June 30, 2016 included $42.4 million of business interruption proceeds associated with a litigation settlement. The total litigation settlement received was approximately $49.0 million, of which a total of $6.8 million was recognized as a reduction in general and administrative expenses in the fourth quarter of 2015 and the first quarter of 2016, related to legal expenses incurred as part of the litigation.

Cash Flows from Investing Activities

Net cash used in investing activities was $59.4 million for the first six months of 2016, compared to $344.2 million in the comparable period of 2015. The decrease was primarily due to the cash paid for our equity method investment in Alon USA in the second quarter of 2015, as well as a decline in our capital expenditures in the six months ended June 30, 2016, as compared to the same period in 2015.

Cash used in investing activities includes the cash portion of our capital expenditures, which was $28.3 million and $119.7 million for the six months ended June 30, 2016 and 2015, respectively. Total capital expenditures during the first six months of 2016 were $19.6 million, of which $6.9 million was spent on projects in the refining segment, $4.4 million was spent in the retail segment, $1.9 million was spent in the logistics segment and $6.4 million was spent at the holding company level. During the six months ended June 30, 2015, we spent $138.4 million, of which $123.2 million was spent on projects in our refining segment, $3.5 million was spent in our retail segment, $9.8 million was spent in our logistics segment and $1.9 million was spent at the holding company level.

Cash Flows from Financing Activities

Net cash used in financing activities was $22.3 million for the six months ended June 30, 2016, compared to net cash provided of $204.8 million in the comparable 2015 period. The decrease in net cash from financing activities was primarily due to net repayments under our revolving credit facilities of $0.9 million in the six months ended June 30, 2016, compared to net borrowings of $88.1 million in the comparable period of 2015, as well as net repayments under our term loans of $34.1 million during the six months ended June 30, 2016, compared to borrowings of $149.1 million in the comparable 2015 period. These decreases were partially offset by $50.4 million in proceeds from product financing agreements in the six months ended June 30, 2016. We did not have any proceeds from product financing agreements in the comparable period of 2015.

Cash Position and Indebtedness

As of June 30, 2016, our total cash and cash equivalents were $377.1 million and we had total indebtedness of approximately $941.4 million. Unused credit commitments and borrowing base availability under our four separate revolving credit facilities, as applicable, was approximately $624.7 million and we had letters of credit issued of $104.6 million. We believe we were in compliance with our covenants in all debt facilities as of June 30, 2016. See Note 6 of the condensed consolidated financial statements in Item 1, Financial Statements, for additional information about our four separate revolving credit facilities.

46

Capital Spending

A key component of our long-term strategy is our capital expenditure program. Our capital expenditures for the six months ended June 30, 2016 were $19.6 million, of which approximately $6.9 million was spent in our refining segment, $4.4 million in our retail segment, $1.9 million in our logistics segment and $6.4 million at the holding company level. The following table summarizes our actual capital expenditures for the six months ended June 30, 2016 and planned capital expenditures for the full year 2016 by operating segment and major category (in millions):

	Full Year 2016 Forecast		Six Months Ended June 30, 2016
Refining:
Sustaining maintenance, including turnaround activities	$	16.7	$	4.4
Regulatory	3.0		0.1
Discretionary projects	8.1		2.4
Refining segment total	27.8		6.9
Logistics:
Regulatory	1.5		0.1
Sustaining maintenance	9.3		1.3
Discretionary projects	3.5		0.5
Logistics segment total	14.3		1.9
Retail:
Sustaining maintenance	8.2		2.5
Growth/profit improvements	4.6		1.7
Retrofit/rebrand/re-image	0.2		—
Raze and rebuild/new/land	0.2		0.2
Retail segment total	13.2		4.4
Other:
Growth/profit improvements	7.5		4.8
New builds/land	1.1		1.6
Other total	8.6		6.4
Total capital spending	$	63.9	$	19.6

Our total capital spending forecast for 2016 of $63.9 million is a substantial reduction as compared to our actual spending for the year ended 2015 of $218.6 million, during which we completed significant maintenance and improvement capital projects. The 2016 forecast is focused primarily on maintenance spending.

The amount of our capital expenditure budget is subject to change due to unanticipated increases in the cost, scope and completion time for our capital projects. For example, we may experience increases in the cost of and/or timing to obtain necessary equipment required for our continued compliance with government regulations or to complete improvement projects or scheduled maintenance activities. Additionally, the scope and cost of employee or contractor labor expense related to installation of that equipment could exceed our projections. Our capital expenditure budget may also be revised

as management continues to evaluate projects for reliability or profitability.

Price Risk Management Activities. At times, we enter into commodity derivative contracts to manage our price exposure to our inventory positions, future purchases of crude oil and ethanol, future sales of refined products or to fix margins on future production. In accordance with ASC 815, Derivatives and Hedging ("ASC 815"), all of these commodity contracts are recorded at fair value, and any change in fair value between periods has historically been recorded in the profit and loss section of our consolidated financial statements, unless, at inception, the Company elects to designate the contracts as cash flow hedges under ASC 815. Gains or losses on commodity derivative contracts accounted for as cash flow hedges are recognized in other comprehensive income on the consolidated balance sheets and, ultimately, when the forecasted transactions are completed in net sales or cost of goods sold in the consolidated statements of income.

Unless otherwise provided in a separate agreement between you and Delek US Holdings, Inc. (the “Company”), the following terms and conditions apply to your award of restricted stock units (“RSUs”) under the Delek US Holdings, Inc. 2016 Long-Term Incentive Plan (the “Plan”). The RSU award is made with respect to shares of the Company’s Common Stock, $0.01 par value (the “Common Stock”), upon the terms and conditions set forth herein and the Plan. Capitalized terms used but not defined herein shall have the meanings ascribed to such terms in the Plan.

1.Award. The Company hereby grants, and you accept, an award of RSUs pursuant to the Plan. RSUs constitute an unfunded and unsecured promise of the Company to deliver to you, subject to the satisfaction of vesting conditions and the other terms and conditions of this Agreement and the Plan, that number of shares of Common Stock referenced by the RSUs. Until such delivery, you shall have the rights of a general unsecured creditor of the Company with respect to the RSUs and shall not have any rights as a stockholder of the Company.

2. Vesting. All vesting is subject to your continuous employment or other service with the Company or its affiliates through each applicable vesting date. You will forfeit the unvested portion of the RSUs upon the termination of your employment or other service with the Company or its affiliates.

3.Issuance / Delivery of Shares. Except as otherwise provided herein, a stock certificate registered in your name representing the shares of Common Stock referenced by the vested portion of the RSUs shall be issued and delivered to you promptly following the vesting date. You shall have no right to receive any dividend or distribution with respect to such shares if the record date for such dividend or distribution is prior to the vesting date of the RSUs.

4.Dividend Equivalents. You shall be credited with dividend equivalents for any cash dividends paid on the number of shares of Common Stock covered by the RSUs as a cash deferral which deferral shall be settled in cash upon vesting of the related RSUs, subject to the same terms and conditions as such RSUs.

5.     Withholding / Consents. The delivery of shares of Common Stock represented by RSUs is conditioned on your satisfaction of any applicable withholding taxes in accordance with the Plan and any other agreement(s) between you and the Company. Your rights in respect of the RSUs are conditioned on the receipt to the full satisfaction of the Company of any required consents that the Company may determine to be necessary or advisable, including, without limitation, consents to deductions from wages or other arrangements satisfactory to the Company.

6.Nontransferability. You may not pledge, hypothecate or otherwise encumber the RSUs or subject them to any lien, obligation or liability of yours to any party (other than the Company or an affiliate thereof), or assign or transfer (collectively, “Transfer”) by you other than by will or the laws of descent and distribution or to a beneficiary upon your death. Any attempt by you or any other person claiming against, through or under you to cause the RSUs or any part of it to

be Transferred in any manner and for any purpose shall be null and void and without effect upon the Company, you or any other person.

7.Compliance with Law / Transfer Orders / Legends. The Company will not be obligated to issue or deliver shares of Common Stock pursuant to this award unless the issuance and delivery of such shares complies with applicable law, including, without limitation, the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, and the requirements of any stock exchange or market upon which the Common Stock may then be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance.

The Company may cause a legend or legends to be placed on any such certificates to make appropriate reference to such restrictions.

8.No Employment or Other Rights. Nothing contained in the Plan or this award shall confer any right upon you with respect to the continuation of your employment or other service with the Company or its affiliates or interfere in any way with the right of the Company and its affiliates at any time to terminate such employment or other service or to increase or decrease, or otherwise adjust, the other terms and conditions of your employment or other service.

9.Provisions of the Plan / Electronic Delivery. The provisions of the Plan shall govern if and to the extent that there are inconsistencies between those provisions and the provisions hereof.

Exhibit 10.6

GENERAL TERMS AND CONDITIONS FOR

STOCK APPRECIATION RIGHTS AWARDS UNDER THE

DELEK US HOLDINGS, INC. 2016 LONG-TERM INCENTIVE PLAN

Delek US Holdings, Inc. (the “Company”) hereby grants, and you accept, an award of stock-settled stock appreciation rights (“SARs”) under the Company’s 2016 Long-Term Incentive Plan (the “Plan”). Unless otherwise provided in a separate agreement between you and the Company, the following terms and conditions apply to your award of SARs. The SAR award is made with respect to shares of the Company’s Common Stock, $0.01 par value (the “Common Stock”), upon the terms and conditions set forth herein and the Plan. Capitalized terms used but not defined herein shall have the meanings ascribed to such terms in the Plan.

1.Base Price. The base price of the SARs is the fair market value of Common Stock (the “FMV”) on the date the SAR was granted (the “Grant Date”). For purposes of establishing the base price of the SARs, the FMV shall be the New York Stock Exchange (“NYSE”) closing price of our Common Stock on the Grant Date (or the last previous NYSE closing price if the Grant Date occurs on a day when the NYSE is not open for trading).

2.Vesting / Term. All vesting is conditioned upon your continuous employment or other service with the Company or its affiliates through the applicable vesting dates. The term of the SARs shall be for a period of ten years from the Grant Date, subject to earlier termination as provided herein and the Plan.

3.Termination of Employment or Other Service.

(a)Death / Disability. If your employment or other service with the Company or its affiliates is terminated due to your death or Disability (unless the Company determines that such death or Disability occurs as a result of conduct that constitutes Cause), then: (i) that portion of the SARs, if any, that is not vested and exercisable on the date of your termination of employment or other service shall automatically become exercisable and (ii) the SARs shall remain exercisable by you (or, in the event of death, your beneficiary) during the one year period following the date of termination but in no event after expiration of the stated term hereof and, to the extent not exercised during such period, shall thereupon terminate.

(b)Termination for Cause. If your employment or other service is terminated by the Company or its affiliates for Cause, then the SAR (whether or not then vested and exercisable) shall immediately terminate and cease to be exercisable. For purposes hereof, “Cause” shall have the meaning ascribed to such term in any employment agreement between you and the Company or, if there is no employment agreement or such term is not defined in the employment agreement, then, for the purposes hereof, the term “Cause” shall have the meaning ascribed to it in the Plan.

(c)Other Termination. If your employment or other service with the Company or its affiliates is terminated for any reason other than those set forth in Section 3(a) or 3(b) above, then: (i) that portion of the SARs, if any, that is vested and exercisable on the date of termination shall remain exercisable by you during the 30 calendar day period following the date of termination but in no event after expiration of the stated term hereof and, to the extent not exercised during such period, shall thereupon terminate, and (ii) that portion of the SARs, if any, that is not vested and exercisable on the date of termination shall thereupon terminate.

4.Exercise / Payment.

(a)Subject to the provisions hereof and the Plan, upon the exercise of an SAR hereunder, you (or your beneficiary, as the case may be) shall be entitled to receive, in the Company’s sole discretion, cash and/or a number of whole shares having a FMV equal to the product of X and Y, where:

X = the number of whole SAR shares being exercised, and

Y = the excess of (i) the FMV on the date of exercise over (ii) the base price per share with respect to the SARs being exercised.

(b)    You may exercise SARs that are vested and exercisable hereunder by delivering to the Secretary of the Company (i) a written notice of such exercise specifying the number of shares of Common Stock covered by such exercise, and (ii) payment in full of the withholding taxes due in connection with the exercise, unless other arrangements satisfactory to the Company are made for the satisfaction of such payment.

(c)    Upon the exercise of an SAR hereunder, the applicable tax withholding obligation may be paid (i) in cash or by check (including the withholding of cash sufficient to cover the withholding obligation from the proceeds of a cash settlement of the SARs); (ii) at the discretion of the Compensation Committee of the

Company’s Board of Directors (the “Committee”), by (A) the delivery of previously-owned shares of Common Stock, (B) means of a cashless exercise procedure in connection with a stock settlement (including, without limitation, the withholding of shares from the settlement or through a broker-assisted cashless exercise), (C) any other legal means that may be acceptable to the Committee, or (D) by a combination of the foregoing; or (iii) at the discretion of the Committee, in any combination of the above.

5.Rights as Stockholder. If and to the extent SARs are settled in shares of Common Stock, no such shares shall be issued until the applicable tax withholding obligation is fully satisfied. You have no rights as a stockholder with respect to any shares covered by SARs unless, until and except to the extent that such shares are issued to you.

6.Nontransferability. You may not pledge, hypothecate or otherwise encumber the SARs or subject them to any of your liens, obligations or liabilities to any party (other than the Company or an affiliate thereof), or assigned or transferred (collectively, “Transferred”) by you other than by will or the laws of descent and distribution or to a beneficiary upon your death, and the SAR may be exercised during your lifetime only by you or your guardian or legal representative. Any attempt by you or any other person claiming against, through or under you to cause the SAR or any part of it to be Transferred in any manner and for any purpose shall be null and void and without effect upon the Company, you or any other person.

7.Compliance With Law / Transfer Orders / Legends. If and to the extent the SARs are settled in the form of shares of Common Stock, the Company will not be obligated to issue or deliver such shares unless the issuance and delivery of such shares complies with applicable law, including, without limitation, the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, and the requirements of any stock exchange or market upon which the Common Stock may then be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance. All certificates for shares of Common Stock delivered under the SARs shall be subject to such stock-transfer orders and other restrictions as the Company may deem advisable under the rules, regulations, and other requirements of the United States Securities and Exchange Commission, any stock exchange or market upon which the Common Stock may then be listed, and any applicable federal or state securities law. The Company may cause a legend or legends to be placed on any such certificates to make appropriate reference to such restrictions.

8.No Employment or Other Rights. Nothing contained in these terms or in the Plan shall confer upon you any right with respect to the continuation of your employment or other service with the Company or its affiliates or interfere in any way with the right of the Company and its affiliates at any time to terminate your employment or other service or to modify the terms and conditions of your employment or other service.

9.Provisions of the Plan / Electronic Delivery. The provisions of the Plan shall govern if and to the extent that there are inconsistencies between those provisions and the provisions hereof. As a participant in the Plan, you are entitled to receive certain information regarding the Plan and its operations and such information is available to you electronically at www.benefitsonline.com. You may receive a paper copy of this information at no cost to you if you contact the Company by telephone at (615) 771-6701 or by regular United States mail at 7102 Commerce Way, Brentwood, Tennessee 37027. By accepting this award, you hereby consent to the electronic delivery of the Plan to you as set forth herein and acknowledge receipt of a copy of the Plan prior to your acceptance of this award.

10.Miscellaneous. These terms and conditions shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns. These terms and conditions shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to its principles of conflicts of law. These terms and conditions constitute the entire agreement between the parties with respect to the subject matter hereof and, except as otherwise provided in the Plan, may not be modified other than by written instrument executed by the parties.

Organization and Basis of Presentation

Delek US Holdings, Inc. is the sole shareholder or owner of membership interests of Delek Refining, Inc. ("Refining"), Delek Finance, Inc., Delek Marketing & Supply, LLC, Lion Oil Company ("Lion Oil"), Delek Renewables, LLC, Delek Rail Logistics, Inc., Delek Logistics Services Company, MAPCO Express, Inc. ("MAPCO Express"), MAPCO Fleet, Inc., NTI Investments, LLC, GDK Bearpaw, LLC, Delek Helena, LLC, Commerce Way Insurance Company, Inc., Delek Transportation, LLC and Delek Land Holdings, LLC. Unless otherwise indicated or the context requires otherwise, the terms "we," "our," "us," "Delek" and the "Company" are used in this report to refer to Delek US Holdings, Inc. and its consolidated subsidiaries. Delek is listed on the New York Stock Exchange under the symbol "DK."

Our condensed consolidated financial statements include the accounts of Delek and its consolidated subsidiaries. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. Generally Accepted Accounting Principles ("GAAP") have been condensed or omitted, although management believes that the disclosures herein are adequate to make the financial information presented not misleading. Our unaudited condensed consolidated financial statements have been prepared in conformity with GAAP applied on a consistent basis with those of the annual audited financial statements included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission ("SEC") on February 29, 2016 (the "Annual Report on Form 10-K") and in accordance with the rules and regulations of the SEC. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto for the year ended December 31, 2015 included in our Annual Report on Form 10-K.

Our condensed consolidated financial statements include Delek Logistics Partners, LP ("Delek Logistics"), a variable interest entity. As the general partner of Delek Logistics, we have the sole ability to direct the activities of Delek Logistics that most significantly impact its economic performance. We are also considered to be the primary beneficiary for accounting purposes and are Delek Logistics' primary customer. As Delek Logistics does not derive an amount of gross margin material to us from third parties, there is limited risk to Delek associated with Delek Logistics' operations. However, in the event that Delek Logistics incurs a loss, our operating results will reflect Delek Logistics' loss, net of intercompany eliminations, to the extent of our ownership interest in Delek Logistics.

In the opinion of management, all adjustments necessary for a fair presentation of the financial position and the results of operations for the interim periods have been included. All significant intercompany transactions and account balances have been eliminated in consolidation. All adjustments are of a normal, recurring nature. Operating results for the interim period should not be viewed as representative of results that may be expected for any future interim period or for the full year.

Certain prior period amounts have been reclassified in order to conform to the current year presentation. Additionally, we corrected an immaterial error in the prior period in the consolidated statement of cash flows.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

New Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board ("FASB") issued guidance that requires organizations to use historical experience, current conditions, reasonable and supportable forecasts and forward-looking information in the measurement of all expected credit losses on financial instruments to more accurately estimate those losses. This guidance is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted after December 15, 2018, and interim periods within those fiscal years. We expect to adopt this guidance on or before the effective date and are currently evaluating the impact adopting this new guidance will have on our business, financial condition or results of operations.

In March 2016, the FASB issued guidance that simplifies several aspects of the accounting for share-based payment award transactions, including the accounting for excess tax benefits and deficiencies, classification of awards as either equity or liabilities and classification of excess tax benefits on the statement of cash flows. This guidance is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years and can be early adopted for any interim or annual financial statements that have not yet been issued. Early adoption is permitted. We expect to adopt this guidance on or before the effective date and are currently evaluating the impact adopting this new guidance will have on our business, financial condition or results of operations.

In February 2016, the FASB issued guidance that requires the recognition of a lease liability and a right-of-use asset, initially measured at the present value of the lease payments, in the statement of financial position for all leases previously accounted for as operating leases. This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. We expect to adopt this guidance on or before the effective date and are currently evaluating the impact adopting this new guidance will have on our business, financial condition or results of operations.

In February 2015, the FASB issued guidance that amends and simplifies the requirements for consolidation and provides additional guidance to reporting entities in evaluating whether certain legal entities, such as limited partnerships, limited liability corporations and securitization structures, should be consolidated. This guidance is effective for interim and annual periods beginning after December 15, 2015. We adopted this guidance on the effective date and the adoption did not have a material impact on our business, financial condition or results of operations.

Schedule of Equity Method Investments [Line Items]

Equity Method Investments and Joint Ventures Disclosure [Text Block]

Equity Method Investments

On May 14, 2015, Delek acquired from Alon Israel Oil Company, Ltd. ("Alon Israel") approximately 33.7 million shares of common stock (the "ALJ Shares") of Alon USA Energy, Inc. (NYSE: ALJ) ("Alon USA") pursuant to the terms of a stock purchase agreement with Alon Israel dated April 14, 2015 (the "Alon Acquisition"). The ALJ Shares represented an equity interest in Alon USA of approximately 48%. We acquired the ALJ Shares for the following combination of cash, stock and seller-financed debt:

• Delek issued 6,000,000 restricted shares of its common stock, par value $0.01 per share, to Alon Israel;

• Delek issued an unsecured $145.0 million term promissory note payable to Alon Israel (the "Alon Israel Note") (see Note 6 for further information);

• Delek paid Alon Israel $200.0 million in cash at closing funded with a combination of cash on hand and borrowings under the Lion Term Loan (as defined in Note 6); and

• Delek agreed to pay Alon Israel $5.0 million of additional cash consideration, to be paid ratably in annual installments over a period of five years.

Delek will also issue an additional 200,000 restricted shares of its common stock to Alon Israel if the closing price of Delek's common stock is greater than $50.00 per share for at least 30 consecutive trading days that end on or before May 14, 2017.

As of June 30, 2016, our investment balance in Alon USA was $526.4 million and the excess of our initial investment over our net equity in the underlying net assets of Alon USA was approximately $258.1 million. This excess is included in equity method investments in our consolidated balance sheet and a portion has been attributed to property, plant and equipment and definite lived intangible assets. These portions of the excess are being amortized as a reduction to earnings from equity method investments on a straight-line basis over the lives of the related assets. The earnings or losses from this equity method investment reflected in our consolidated statements of income include our share of net earnings or losses directly attributable to this equity method investment, and amortization of the excess of our investment balance over the underlying net assets of Alon USA. As of June 30, 2016, the market value of our ALJ Shares was $218.3 million, based on quoted market prices. We evaluated our investment in Alon USA as of June 30, 2016 and have determined that the decline in the market value of the ALJ Shares is not other than temporary and, therefore, it was not necessary to record an impairment charge on our investment at June 30, 2016. In determining whether the decline is other than temporary, we considered the cyclical nature of our industry, Alon USA's historical performance, its performance in relation to its peers and the current economic environment.

Below is summarized financial information of the financial position and results of operations of Alon USA (in millions):

Also, in March 2015, Delek Logistics entered into two joint ventures that are currently constructing logistics assets, which will serve third parties and subsidiaries of Delek. Delek Logistics' investment in these joint ventures is expected to be financed through a combination of cash from operations and borrowings under the DKL Revolver (as defined in Note 6). As of June 30, 2016, Delek Logistics' investment balance in these joint ventures was $73.4 million and was accounted for using the equity method. One of the joint venture projects is expected to be operational in August 2016.

Due to a lower crude oil and refined product pricing environment experienced since the end of 2014, market prices have declined to a level below the average cost of our inventories. At June 30, 2016, we recorded a pre-tax lower of cost or market reserve of $32.8 million, of which $31.7 million related to LIFO inventory, which is subject to reversal in subsequent periods, not to exceed LIFO cost, should market prices recover. At December 31, 2015, we recorded a pre-tax lower of cost or market reserve of $50.9 million, of which $49.8 million related to LIFO inventory, which reversed in the first quarter of 2016, as the inventories associated with the valuation adjustment at the end of 2015 were sold or used. We recognized net lower of cost or market gains of $13.0 million and $16.9 million for the three and six months ended June 30, 2016, respectively, and $29.9 million and $31.9 million for the three and six months ended June 30, 2015, respectively. These gains were recorded as a component of cost of goods sold in the consolidated statements of income.

At June 30, 2016 and December 31, 2015, the excess of replacement cost (FIFO) over the carrying value (LIFO) of the Tyler refinery inventories was $0.5 million and $0.1 million, respectively.

Permanent Liquidations

We incurred a permanent reduction in a LIFO layer resulting in a liquidation gain (loss) in our refinery inventory of $0.9 million and $(2.4) million during the three and six months ended June 30, 2016, respectively, and $(6.6) million and $(10.2) million during the three and six months ended June 30, 2015, respectively. These liquidations were recognized as a component of cost of goods sold.

Crude Oil Supply and Inventory Purchase Agreement [Abstract]

Crude Oil Supply and Inventory Purchase Agreement

Crude Oil Supply and Inventory Purchase Agreement

Delek has a Master Supply and Offtake Agreement (the "Supply and Offtake Agreement") with J. Aron & Company ("J. Aron"). Throughout the term of the Supply and Offtake Agreement, which will expire on April 30, 2017, Lion Oil and J. Aron will identify mutually acceptable contracts for the purchase of crude oil from third parties and J. Aron will supply up to 100,000 barrels per day ("bpd") of crude to the El Dorado refinery. Crude oil supplied to the El Dorado refinery by J. Aron will be purchased daily at an estimated average monthly market price by Lion Oil. J. Aron will also purchase all refined products from the El Dorado refinery at an estimated market price daily, as they are produced. These daily purchases and sales are trued-up on a monthly basis in order to reflect actual average monthly prices. We have recorded a payable related to this monthly settlement of $3.4 million and $11.4 million as of June 30, 2016 and December 31, 2015, respectively. Also pursuant to the Supply and Offtake Agreement and other related agreements, Lion Oil will endeavor to arrange potential sales by either Lion Oil or J. Aron to third parties of the products produced at the El Dorado refinery or purchased from third parties. In instances where Lion Oil is the seller to such third parties, J. Aron will first transfer the applicable products to Lion Oil.

While title to the inventories is retained by J. Aron, this arrangement is accounted for as a product financing arrangement. Delek incurred fees payable to J. Aron of $2.6 million and $5.0 million during the three and six months ended June 30, 2016, respectively, and $2.8 million and $5.3 million during the three and six months ended June 30, 2015, respectively. These amounts are included as a component of interest expense in the condensed consolidated statements of income. Upon any termination of the Supply and Offtake Agreement, including in connection with a force majeure event, the parties are required to negotiate with third parties for the assignment to us of certain contracts, commitments and arrangements, including procurement contracts, commitments for the sale of product, and pipeline, terminalling, storage and shipping arrangements.

Upon the expiration of the Supply and Offtake Agreement on April 30, 2017, or upon any earlier termination, Delek will be required to repurchase the consigned crude oil and refined products from J. Aron at then prevailing market prices. At June 30, 2016, Delek had 3.0 million barrels of inventory consigned for J. Aron, and we have recorded liabilities associated with this consigned inventory of $129.8 million in the condensed consolidated balance sheet.

MAPCO Revolver

Our subsidiary, MAPCO Express, has a revolving credit facility with Fifth Third Bank, as administrative agent, and a syndicate of lenders that was amended and restated on May 6, 2014 (the "MAPCO Revolver"). The MAPCO Revolver consists of a $160.0 million revolving credit limit which includes (i) a $10.0 million swing line loan sub-limit; (ii) a $40.0 million letter of credit sub-limit; and (iii) an accordion feature which permits an increase in borrowings by up to $50.0 million, subject to additional lender commitments. As of June 30, 2016, we had $106.5 million outstanding under the MAPCO Revolver, as well as letters of credit issued of $2.9 million, with approximately $50.6 million of unused credit commitments. Borrowings under the MAPCO Revolver are secured by (i) substantially all the assets of MAPCO Express and its subsidiaries, subject to certain exceptions and limitations, (ii) all of Delek’s shares in MAPCO Express, and (iii) a limited guaranty provided by Delek of up to $50.0 million in obligations. The MAPCO Revolver will mature on May 6, 2019. The MAPCO Revolver bears interest based on predetermined pricing grids which allow us to choose between base rate loans or London Interbank Offered Rate ("LIBOR") rate loans. At June 30, 2016, the weighted average borrowing rate under the MAPCO Revolver was approximately 3.1%. Additionally, the MAPCO Revolver requires us to pay a leverage ratio dependent quarterly fee on the average unused revolving commitment. As of June 30, 2016, this fee was 0.35% per year.

DKL Revolver

Delek Logistics has a $700.0 million senior secured revolving credit agreement with Fifth Third Bank, as administrative agent, and a syndicate of lenders (the "DKL Revolver"). Delek Logistics and each of its existing subsidiaries are borrowers under the DKL Revolver. The DKL Revolver contains a dual currency borrowing tranche that permits draw downs in U.S. or Canadian dollars and an accordion feature whereby Delek Logistics can increase the size of the credit facility to an aggregate of $800.0 million, subject to receiving increased or new commitments from lenders and the satisfaction of certain other conditions precedent.

The obligations under the DKL Revolver are secured by a first priority lien on substantially all of Delek Logistics' tangible and intangible assets. Additionally, a subsidiary of Delek provides a limited guaranty of Delek Logistics' obligations under the DKL Revolver. The guaranty is (i) limited to an amount equal to the principal amount, plus unpaid and accrued interest, of a promissory note made by Delek in favor of the subsidiary guarantor (the "Holdings Note") and (ii) secured by the subsidiary guarantor's pledge of the Holdings Note to the DKL Revolver lenders. As of June 30, 2016, the principal amount of the Holdings Note was $102.0 million.

The DKL Revolver will mature on December 30, 2019. Borrowings under the DKL Revolver bear interest at either a U.S. base rate, Canadian prime rate, LIBOR, or a Canadian Dealer Offered Rate, in each case plus applicable margins, at the election of the borrowers and as a function of draw down currency. The applicable margin, in each case, varies based upon Delek Logistics' leverage ratio, which is defined as the ratio of total funded debt to EBITDA for the most recently ended four fiscal quarters. At June 30, 2016, the weighted average borrowing rate was approximately 2.8%. Additionally, the DKL Revolver requires Delek Logistics to pay a leverage ratio dependent quarterly fee on the average unused revolving commitment. As of June 30, 2016, this fee was 0.40% per year. As of June 30, 2016, Delek Logistics had approximately $362.6 million of outstanding borrowings under the credit facility, as well as letters of credit issued of $7.5 million. Unused credit commitments under the DKL Revolver, as of June 30, 2016, were approximately $329.9 million.

Wells ABL

Our subsidiary, Delek Refining, Ltd., has an asset-based loan credit facility with Wells Fargo Bank, National Association, as administrative agent, and a syndicate of lenders (the "Wells ABL") that consists of (i) a $600.0 million revolving loan (the "Wells Revolving Loan"), which includes a $55.0 million swing line loan sub-limit and a $550.0 million letter of credit sub-limit, (ii) a $70.0 million delayed single draw term loan (the "Wells Term Loan"), and (iii) an accordion feature which permits an increase in the size of the revolving credit facility to an aggregate of $875.0 million, subject to additional lender commitments and the satisfaction of certain other conditions precedent. The Wells Revolving Loan matures on January 16, 2019 and the Wells Term Loan matures on December 31, 2016. The Wells Term Loan is subject to repayment in level principal installments of approximately $5.8 million per quarter, with a final balloon payment due on December 31, 2016. As of June 30, 2016, under the Wells ABL, we had letters of credit issued totaling approximately $91.5 million and no amounts outstanding under the Wells Revolving Loan; under the Wells Term Loan we had approximately $29.2 million outstanding. The obligations under the Wells ABL are secured by (i) substantially all the assets of Refining and its subsidiaries, with certain limitations, (ii) a limited guarantee provided by Delek in an amount up to $15.0 million and (iii) a limited guarantee provided by Lion Oil in an amount equal to the sum of the face amount of all letters of credit issued on behalf of Lion Oil under the Wells ABL and any loans made by Refining or its subsidiaries to Lion Oil. Under the facility, revolving loans and letters of credit are provided subject to availability requirements which are determined pursuant to a borrowing base calculation as defined in the credit agreement. The borrowing base as calculated is primarily supported by cash, certain accounts receivable and certain inventory. Borrowings under the Wells Revolving Loan and Wells Term Loan bear interest based on separate predetermined pricing grids which allow us to choose between base rate loans or LIBOR rate loans. At June 30, 2016, the weighted average borrowing rate under the Wells Term Loan was approximately 4.2%. Additionally, the Wells ABL requires us to pay a quarterly unused credit commitment fee. As of June 30, 2016, this fee was approximately 0.38% per year. Unused borrowing base availability, as calculated and reported under the terms of the Wells ABL credit facility, as of June 30, 2016, was $244.2 million.

Reliant Bank Revolver

We have a revolving credit agreement with Reliant Bank, which was amended on May 26, 2016 (the "Reliant Bank Revolver"). The Reliant Bank Revolver provides for unsecured loans of up to $17.0 million. As of June 30, 2016, we had $17.0 million outstanding under this facility. The Reliant Bank Revolver matures on June 28, 2018, and bears interest at a fixed rate of 5.25% per annum. The Reliant Bank Revolver requires us to pay a quarterly fee of 0.50% per year on the average available revolving commitment. As of June 30, 2016, we had no unused credit commitments under the Reliant Bank Revolver.

Promissory Notes

In 2011, Delek began construction on new MAPCO Mart convenience stores (each a "Build-to-Suit Development" or "BTS"). In order to fund these construction projects, we entered into separate notes for each BTS project with Standard Insurance Company (collectively, the "Notes") varying in size from approximately $1.0 million to $2.2 million. The Notes bear interest at fixed rates, ranging from 5.0% to approximately 6.4% per annum. Each of the Notes is secured by the land or leasehold interest, as applicable, and the building and equipment of its respective completed MAPCO Mart. Under the terms of each Note, beginning on the first day of the eleventh month following the initial fund advancement, payments of principal on each respective Note are due over a ten-year term calculated using a 25-year amortization schedule. If any Note is not paid in full after the initial ten-year period, we may continue to make monthly payments under the Note; however, the interest rate will reset pursuant to the terms of the Note. There is also an additional interest rate reset after the first 20-year period. The final maturity dates of the Notes range from June 1, 2036 to December 1, 2041. As of June 30, 2016, we had amounts drawn under 33 Notes related to these BTS projects, for a total amount of approximately $53.0 million outstanding under the Notes.

On April 29, 2011, Delek entered into a $50.0 million promissory note (the "Ergon Note") with Ergon, Inc. ("Ergon") in connection with the closing of our acquisition of Lion Oil. As of June 30, 2016, $10.0 million was outstanding under the Ergon Note. The Ergon Note requires Delek to make annual amortization payments of $10.0 million each, commencing April 29, 2013. The Ergon Note matures on April 29, 2017. Interest under the Ergon Note is computed at a fixed rate equal to 4.00% per annum.

On May 14, 2015, in connection with the closing of the Company’s acquisition of the ALJ Shares, the Company issued the Alon Israel Note, which was payable to Alon Israel. The Alon Israel Note bears interest at a fixed rate of 5.50% per annum and requires five annual principal amortization payments of $25.0 million beginning in January 2016 followed by a final principal amortization payment of $20.0 million at maturity on January 4, 2021. In October 2015, we prepaid the first annual principal amortization payment in the amount of $25.0 million, along with all interest due on the prepaid amount. On December 22, 2015, Alon Israel assigned the remaining $120.0 million of principal and all accrued interest due under the Alon Israel Note to assignees under four new notes in substantially the same form and on the same terms as the Alon Israel Note (collectively, the "Alon Successor Notes"). The $120.0 million in total principal of the four Alon Successor Notes collectively require the same principal amortization payments and schedule as under the Alon Israel Note, with payments due under each Alon Successor Note commensurate to such note's pro rata share of $120.0 million in assigned principal. As of June 30, 2016, a total principal amount of $120.0 million was outstanding under the Alon Successor Notes.

Lion Term Loan

Our subsidiary, Lion Oil, has a term loan credit facility with Fifth Third Bank, as administrative agent, and a syndicate of lenders, which was amended and restated on May 14, 2015 in connection with the Company’s closing of the Alon Acquisition to, among other things, increase the total loan size from $99.0 million to $275.0 million (the "Lion Term Loan"). The Lion Term Loan requires Lion Oil to make quarterly principal amortization payments of approximately $6.9 million each, commencing on September 30, 2015, with a final balloon payment due at maturity on May 14, 2020. The Lion Term Loan is secured by, among other things, (i) substantially all the assets of Lion Oil and its subsidiaries (excluding inventory and accounts receivable), (ii) all shares in Lion Oil, (iii) any subordinated and common units of Delek Logistics held by Lion Oil, and (iv) the ALJ Shares. Additionally, the Lion Term Loan is guaranteed by Delek and the subsidiaries of Lion Oil. Interest on the unpaid balance of the Lion Term Loan is computed at a rate per annum equal to LIBOR or a base rate, at our election, plus the applicable margins, subject in each case to an all-in interest rate floor of 5.50% per annum. As of June 30, 2016, $247.5 million was outstanding under the Lion Term Loan and the weighted average borrowing rate was 5.50%.

Restrictive Covenants

Under the terms of our MAPCO Revolver, Wells ABL, DKL Revolver, Reliant Bank Revolver and Lion Term Loan, we are required to comply with certain usual and customary financial and non-financial covenants. Further, although we were not required to comply with separate fixed charge coverage ratio financial covenants under the Wells ABL and the Lion Term Loan during the three and six months ended June 30, 2016, we may be required to comply with these covenants at times when certain trigger thresholds are met, as defined in each of the Wells ABL and Lion Term Loan agreements. We believe we were in compliance with all covenant requirements under each of our credit facilities as of June 30, 2016.

Certain of our credit facilities contain limitations on the incurrence of additional indebtedness, making of investments, creation of liens, dispositions of property, making of restricted payments and transactions with affiliates. Specifically, these covenants may limit the payment, in the form of cash or other assets, of dividends or other distributions, or the repurchase of shares with respect to the equity of our subsidiaries. Additionally, certain of our credit facilities limit our ability to make investments, including extensions of loans or advances to, or acquisitions of equity interests in, or guarantees of obligations of, any other entities.

Interest-Rate Derivative Instruments

Delek had an interest rate cap agreement in place for a notional amount of $45.0 million, which matured in February 2016. This agreement, and similar interest rate hedge agreements in place that matured during 2015, were intended to economically hedge floating interest rate risk related to a portion of our existing debt. However, as we have elected not to apply the permitted hedge accounting treatment, including formal hedge designation and documentation, in accordance with the provisions of Accounting Standards Codification ("ASC") 815, Derivatives and Hedging ("ASC 815"), the fair value of the derivatives is recorded in other current assets in the accompanying condensed consolidated balance sheets with the offset recognized in interest expense in the accompanying condensed consolidated statements of income. The interest rate cap agreement had no fair value as of December 31, 2015.

In accordance with ASC 815, we recorded expense representing cash settlements and changes in estimated fair value of the interest rate derivative agreements of $0.1 million and $0.2 million for the three and six months ended June 30, 2015. This amount is included in interest expense in the accompanying consolidated statement of income. There was no expense related to interest rate derivative agreements for the three and six months ended June 30, 2016.

While Delek has not elected to apply permitted hedge accounting treatment for these interest rate derivatives in accordance with the provisions of ASC 815 in the past, we may choose to apply that treatment for future transactions.

Income Taxes (Notes)

Income Taxes [Abstract]

Income Taxes

Income Taxes

Under ASC 740, Income Taxes (“ASC 740”), companies are required to apply an estimated annual tax rate to interim period results on a year-to-date basis; however, the estimated annual tax rate should not be applied to interim financial results if a reliable estimate cannot be made.  In this situation, the interim tax rate should be based on actual year-to-date results.  Based on our current projections, which have fluctuated as a result of changes in oil prices and the related crack spread, we believe that using actual year-to-date results to compute our effective tax rate will produce a more reliable estimate of our tax expense or benefit for the three and six months ended June 30, 2016.  As such, in contrast with our previous methods of recording income tax expense, we recorded a tax provision for the three and six months ended June 30, 2016 based on actual year-to-date results, in accordance with ASC 740.

Our effective tax rate was 93.8% and 58.2% for the three and six months ended June 30, 2016, respectively, compared to 21.5% and 17.0% for the three and six months ended June 30, 2015, respectively. The increase in our effective tax rate in the three and six months ended June 30, 2016 was primarily due to the change in methodology from using an estimated annual effective tax rate to an actual three and six month effective tax rate, as well as the benefit that we received from certain tax credits and other favorable permanent items impacting our quarterly results.

	June 30,		June 30,
	2016	2015	2016	2015
Weighted average common shares outstanding	61,827,201	60,555,444	61,979,604	58,931,705
Dilutive effect of equity instruments	—	559,027	—	539,224
Weighted average common shares outstanding, assuming dilution	61,827,201	61,114,471	61,979,604	59,470,929

Outstanding common share equivalents totaling 3,114,732 and 2,958,334 were excluded from the diluted earnings per share calculation for the three and six months ended June 30, 2016, respectively, compared to 1,345,220 and 2,236,977 common share equivalents for the three and six months ended June 30, 2015, respectively, as these common share equivalents did not have a dilutive effect under the treasury stock method. These amounts include outstanding common share equivalents totaling 196,540 and 226,860 that were excluded from the diluted earnings per share calculation due to the net loss for the period for the three and six months ended June 30, 2016, respectively.

Segment Data [Abstract]

Segment Data

Segment Data

We aggregate our operating units into three reportable segments: refining, logistics and retail. Our corporate activities, results of certain immaterial operating segments, our equity method investment in Alon USA and intercompany eliminations are reported in the corporate, other and eliminations segment. Decisions concerning the allocation of resources and assessment of operating performance are made based on this segmentation. Management measures the operating performance of each of the reportable segments based on the segment contribution margin.

Segment contribution margin is defined as net sales less cost of sales and operating expenses, excluding depreciation and amortization. Operations which are not specifically included in the reportable segments are included in the corporate and other category, which primarily consists of operating expenses, depreciation and amortization expense and interest income and expense associated with our corporate headquarters.

The refining segment processes crude oil and other purchased feedstocks for the manufacture of transportation motor fuels, including various grades of gasoline, diesel fuel, aviation fuel, asphalt and other petroleum-based products that are distributed through owned and third-party product terminals. The refining segment has a combined nameplate capacity of 155,000 bpd, including the 75,000 bpd Tyler refinery and the 80,000 bpd El Dorado refinery. The refining segment also owns and operates two biodiesel facilities involved in the production of biodiesel fuels and related activities.

Our logistics segment owns and operates crude oil and refined products logistics and marketing assets. The logistics segment generates revenue and subsequently contribution margin by charging fees for gathering, transporting and storing crude oil and for marketing, distributing, transporting and storing intermediate and refined products.

Our retail segment markets gasoline, diesel, other refined petroleum products and convenience merchandise through a network of company-operated retail fuel and convenience stores throughout the southeastern United States. As of June 30, 2016, we had 348 stores in total, consisting of 187 located in Tennessee, 89 in Alabama, 42 in Georgia, 12 in Arkansas, eight in Virginia, six in Kentucky and four in Mississippi. The retail fuel and convenience stores operate under Delek's MAPCO Express^®, MAPCO Mart^®, East Coast^®, Fast Food and Fuel^TM, Favorite Markets^®, Delta Express^® and Discount Food Mart^TM brands. The retail segment also supplied fuel to approximately 65 contracted dealer locations as of June 30, 2016. In the retail segment, management reviews operating results on a divisional basis, where a division represents a specific geographic market. These divisional operating segments exhibit similar economic characteristics, provide the same products and services, and operate in such a manner such that aggregation of these operations is appropriate for segment presentation.

Our refining segment has a services agreement with our logistics segment, which, among other things, requires the refining segment to pay service fees based on the number of gallons sold at the Tyler refinery and a sharing of a portion of the margin achieved in return for providing marketing, sales and customer services. This intercompany transaction fee was $4.2 million and $8.1 million during the three and six months ended June 30, 2016, respectively, and $3.8 million and $6.8 million during the three and six months ended June 30, 2015, respectively. Additionally, the refining segment pays crude transportation, terminalling and storage fees to the logistics segment for the utilization of pipeline, terminal and storage assets. These fees were $30.7 million and $61.7 million during the three and six months ended June 30, 2016, respectively, and $31.9 million and $59.5 million during the three and six months ended June 30, 2015, respectively. The logistics segment also sold $1.4 million and $2.9 million of Renewable Identification Numbers ("RINs") to the refining segment during the three and six months ended June 30, 2016, respectively, and $2.3 million and $3.9 million during the three and six months ended June 30, 2015, respectively. The refining segment recorded sales and fee revenues from the retail and logistics segments in the amount of $97.1 million and $188.5 million during the three and six months ended June 30, 2016, respectively, and $188.9 million and $315.2 million during the three and six months ended June 30, 2015, respectively. All inter-segment transactions have been eliminated in consolidation.

Fair Value Measurements [Abstract]

Fair Value Measurements

Fair Value Measurements

The fair values of financial instruments are estimated based upon current market conditions and quoted market prices for the same or similar instruments. Management estimates that the carrying value approximates fair value for all of Delek’s assets and liabilities that fall under the scope of ASC 825, Financial Instruments.

Delek applies the provisions of ASC 820, Fair Value Measurements ("ASC 820"), which defines fair value, establishes a framework for its measurement and expands disclosures about fair value measurements. ASC 820 applies to our interest rate and commodity derivatives that are measured at fair value on a recurring basis. The standard also requires that we assess the impact of nonperformance risk on our derivatives. Nonperformance risk is not considered material at this time.

ASC 820 requires disclosures that categorize assets and liabilities measured at fair value into one of three different levels depending on the observability of the inputs employed in the measurement. Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Level 2 inputs are observable inputs other than quoted prices included within Level 1 for the asset or liability, either directly or indirectly through market-corroborated inputs. Level 3 inputs are unobservable inputs for the asset or liability reflecting our assumptions about pricing by market participants.

Over the counter ("OTC") commodity swaps, physical commodity purchase and sale contracts and interest rate swaps and caps are generally valued using industry-standard models that consider various assumptions, including quoted forward prices, spot prices, interest rates, time value, volatility factors and contractual prices for the underlying instruments, as well as other relevant economic measures. The degree to which these inputs are observable in the forward markets determines the classification as Level 2 or 3. Our contracts are valued based on exchange pricing and/or price index developers such as Platts or Argus and are, therefore, classified as Level 2.

The U.S. Environmental Protection Agency ("EPA") requires certain refiners to blend biofuels into the fuel products they produce pursuant to the EPA’s Renewable Fuel Standard - 2.  Alternatively, credits called RINs, which may be generated and/or purchased, can be used to satisfy this obligation instead of physically blending biofuels ("RINs Obligation"). Our RINs Obligation surplus or deficit is based on the amount of RINs we must purchase, net of amounts internally generated and the price of those RINs as of the balance sheet date. The RINs Obligation surplus or deficit is categorized as Level 2 and is measured at fair value based on quoted prices from an independent pricing service.

The fair value hierarchy for our financial assets and liabilities accounted for at fair value on a recurring basis at June 30, 2016 and December 31, 2015, was as follows (in millions):

	As of June 30, 2016
	Level 1		Level 2			Level 3		Total

Total liabilities	—		(369.5		)	—		(369.5		)
Net liabilities	$	—	$	(61.4	)	$	—	$	(61.4	)

The derivative values above are based on analysis of each contract as the fundamental unit of account as required by ASC 820. Derivative assets and liabilities with the same counterparty are not netted where the legal right of offset exists. This differs from the presentation in the financial statements which reflects our policy under the guidance of ASC 815-10-45, wherein we have elected to offset the fair value amounts recognized for multiple derivative instruments executed with the same counterparty and where the legal right of offset exists. As of June 30, 2016 and December 31, 2015, $20.5 million and $23.9 million, respectively, of cash collateral was held by counterparty brokerage firms and has been netted with the net derivative positions with each counterparty.

Derivative Instruments [Abstract]

Derivative Instruments

Derivative Instruments

We use derivatives to reduce normal operating and market risks with the primary objective of reducing the impact of market price volatility on our results of operations. As such, our use of derivative contracts is aimed at:

• limiting the exposure to price fluctuations of commodity inventory above or below target levels at each of our segments;

• managing our exposure to commodity price risk associated with the purchase or sale of crude oil, feedstocks and finished grade fuel products at each of our segments; and

• limiting the exposure to interest rate fluctuations on our floating rate borrowings.

We primarily utilize OTC commodity swaps, generally with maturity dates of three years or less, and interest rate swap and cap agreements to achieve these objectives. OTC commodity swap contracts require cash settlement for the commodity based on the difference between a fixed or floating price and the market price on the settlement date. Interest rate swap and cap agreements economically hedge floating rate debt by exchanging interest rate cash flows, based on a notional amount from a floating rate to a fixed rate. At this time, we do not believe there is any material credit risk with respect to the counterparties to these contracts.

In accordance with ASC 815, certain of our OTC commodity swap contracts have been designated as cash flow hedges and the effective portion of the change in fair value between the execution date and the end of period has been recorded in other comprehensive income. The effective portion of the fair value of these contracts is recognized in income at the time the positions are closed and the hedged transactions are recognized in income.

From time to time, we also enter into futures contracts with supply vendors that secure supply of product to be purchased for use in the normal course of business at our refining and retail segments. These contracts are priced based on an index that is clearly and closely related to the product being purchased, contain no net settlement provisions and typically qualify under the normal purchase exemption from derivative accounting treatment under ASC 815.

The following table presents the fair value of our derivative instruments as of June 30, 2016 and December 31, 2015. The fair value amounts below are presented on a gross basis and do not reflect the netting of asset and liability positions permitted under our master netting arrangements, including cash collateral on deposit with our counterparties. We have elected to offset the recognized fair value amounts for multiple derivative instruments executed with the same counterparty in our financial statements. As a result, the asset and liability amounts below differ from the amounts presented in our condensed consolidated balance sheets (in millions):

⁽¹⁾  As of June 30, 2016 and December 31, 2015, we had open derivative positions representing 11,726,590 barrels and 6,413,150 barrels, respectively, of crude oil and refined petroleum products. Of these open positions, contracts representing 1,983,600 barrels and 3,324,400 barrels were designated as hedging instruments as of June 30, 2016 and December 31, 2015, respectively.

⁽²⁾  As of June 30, 2016 and December 31, 2015, $20.5 million and $23.9 million, respectively, of cash collateral held by counterparties has been netted with the derivatives with each counterparty.

Total (losses) gains on our commodity derivatives recorded in cost of goods sold on the condensed consolidated statements of income for the three and six months ended June 30, 2016 and 2015 are as follows (in millions):

	Three Months Ended June 30,						Six Months Ended June 30,

Total	$	(18.7	)	$	(15.3	)	$	(26.5	)	$	(7.0	)

We also recorded expenses representing cash settlements and changes in estimated fair value of our interest rate derivative agreements of $0.1 million and $0.2 million for the three and six months ended June 30, 2015, respectively. These amounts are included in interest expense in the accompanying consolidated statements of income. There were no interest rate derivative agreements in place as of June 30, 2016 and we recognized no expense related to interest rate derivative agreements for the three and six months ended June 30, 2016.

For cash flow hedges, no component of the derivative instruments’ gains or losses was excluded from the assessment of hedge effectiveness for the three and six months ended June 30, 2016 or 2015. As of June 30, 2016 and December 31, 2015, losses of $25.2 million and $39.7 million, respectively, on cash flow hedges, net of tax, primarily related to future purchases of crude oil and the associated sale of finished grade fuel, remained in accumulated other comprehensive income. Losses of $4.6 million and $9.4 million, net of tax, on settled contracts were reclassified into cost of sales during the three and six months ended June 30, 2016, respectively. (Losses) gains of $(3.5) million and $1.5 million, net of tax, on settled contracts were reclassified into cost of sales during the three and six months ended June 30, 2015, respectively. We estimate that $49.3 million of deferred losses will be reclassified into cost of sales over the next 12 months as a result of hedged transactions that are forecasted to occur. For the six months ended June 30, 2016 and June 30, 2015, there were no amounts reclassified from accumulated other comprehensive income into income as a result of the discontinuation of cash flow hedge accounting.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Commitments and Contingencies

Litigation

In the ordinary conduct of our business, we are from time to time subject to lawsuits, investigations and claims, including environmental claims and employee-related matters.

In 2013, we experienced a security breach by third-party hackers that may have compromised the credit/debit card information of certain of our retail segment customers. The incident involved credit/debit card payments for transactions at certain retail locations between March 19-25, 2013, April 14-15, 2013 and April 20-21, 2013, and several lawsuits have been brought against us as a result of this incident. Although we are unable to definitively determine the extent of any potential losses related to this breach, we do not believe that this incident will have a material adverse effect on our business, financial condition or results of operations.

Although we cannot predict with certainty the ultimate resolution of lawsuits, investigations and claims asserted against us, including civil penalties or other enforcement actions, we do not believe that any currently pending legal proceeding or proceedings to which we are a party will have a material adverse effect on our business, financial condition or results of operations.

Self-insurance

Delek is self-insured for workers’ compensation claims up to $1.0 million on a per-accident basis. We self-insure for general liability claims up to $4.0 million on a per-occurrence basis. We self-insure for auto liability up to $4.0 million on a per-accident basis.

We have umbrella liability insurance available to each of our segments in an amount determined reasonable by management.

Environmental, Health and Safety

We are subject to extensive federal, state and local environmental and safety laws and regulations enforced by various agencies, including the EPA, the United States Department of Transportation, the Occupational Safety and Health Administration, the Texas Commission on Environmental Quality, the Railroad Commission of Texas, the Arkansas Department of Environmental Quality (the "ADEQ") and the Tennessee Department of Environment and Conservation as well as other state and federal agencies. These laws and regulations govern the discharge of materials into the environment, waste management practices, pollution prevention measures and the composition of the fuels we produce, as well as the safe operation of our plants and pipelines and the safety of our workers and the public. Numerous permits or other authorizations are required under these laws and regulations for the operation of our refineries, biodiesel facilities, terminals, pipelines, underground storage tanks ("USTs"), trucks, rail cars and related operations, and may be subject to revocation, modification and renewal.

These laws and permits raise potential exposure to future claims and lawsuits involving environmental and safety matters which could include soil and water contamination, air pollution, personal injury and property damage allegedly caused by substances which we manufactured, handled, used, released or disposed of, transported, or that relate to pre-existing conditions for which we have assumed responsibility. We believe that our current operations are in substantial compliance with existing environmental and safety requirements. However, there have been and will continue to be ongoing discussions about environmental and safety matters between us and federal and state authorities, including notices of violations, citations and other enforcement actions, some of which have resulted or may result in changes to operating procedures and in capital expenditures. While it is often difficult to quantify future environmental or safety related expenditures, we anticipate that continuing capital investments and changes in operating procedures will be required for the foreseeable future to comply with existing and new requirements, as well as evolving interpretations and more strict enforcement of existing laws and regulations.

As of June 30, 2016, we have recorded an environmental liability of approximately $8.5 million, primarily related to the estimated probable costs of remediating or otherwise addressing certain environmental issues of a non-capital nature at the Tyler and El Dorado refineries. This liability includes estimated costs for ongoing investigation and remediation efforts, which were already being performed by the former operators of the Tyler and El Dorado refineries prior to our acquisition of those facilities, for known contamination of soil and groundwater, as well as estimated costs for additional issues which have been identified subsequent to the acquisitions. We expect approximately $0.4 million of this amount to be reimbursable by a prior owner of the El Dorado refinery and have recorded $0.4 million in other current assets in our condensed consolidated balance sheet as of June 30, 2016. Approximately $1.8 million of the total liability is expected to be expended over the next 12 months with most of the balance expended by 2022. In the future, we could be required to extend the expected remediation period or undertake additional investigations of our refineries, pipelines and terminal facilities or convenience stores, which could result in additional remediation liabilities.

We have experienced several crude oil releases from pipelines owned by our logistics segment, including, but not limited to, a release at Magnolia Station in March 2013, a release near Fouke, Arkansas in April 2015 and a release near Woodville, Texas in January 2016. In June 2015, the United States Department of Justice notified Delek Logistics that they were evaluating an enforcement action on behalf of the EPA with regard to potential Clean Water Act violations arising from the March 2013 Magnolia Station release. We are currently attempting to negotiate a resolution to this matter with the EPA and the ADEQ, which may include monetary penalties and/or other relief. Based on current information available to us, we do not believe the total costs associated with these events, whether alone or in the aggregate, including any fines or penalties, will have a material adverse effect upon our business, financial condition or results of operations.

Vendor Commitments

We maintain an agreement with a significant vendor that requires our retail segment to purchase certain general merchandise exclusively from this vendor over a specified period of time. Additionally, we maintain agreements with certain fuel suppliers that contain terms which generally require our retail segment to purchase predetermined quantities of third-party branded fuel for a specified period of time. In certain fuel vendor contracts, penalty provisions exist if our retail segment does not purchase certain minimum quantities of fuel.

Letters of Credit

As of June 30, 2016, we had in place letters of credit totaling approximately $104.6 million with various financial institutions securing obligations primarily with respect to our crude oil purchases for the refining segment, our gasoline and diesel purchases for the logistics segment and our workers’ compensation and general liability self-insurance programs. No amounts were drawn by beneficiaries of these letters of credit at June 30, 2016.

Our unaudited condensed consolidated financial statements have been prepared in conformity with GAAP applied on a consistent basis with those of the annual audited financial statements included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission ("SEC") on February 29, 2016 (the "Annual Report on Form 10-K") and in accordance with the rules and regulations of the SEC.

Consolidation of variable interest entity policy

Our condensed consolidated financial statements include Delek Logistics Partners, LP ("Delek Logistics"), a variable interest entity. As the general partner of Delek Logistics, we have the sole ability to direct the activities of Delek Logistics that most significantly impact its economic performance. We are also considered to be the primary beneficiary for accounting purposes and are Delek Logistics' primary customer. As Delek Logistics does not derive an amount of gross margin material to us from third parties, there is limited risk to Delek associated with Delek Logistics' operations. However, in the event that Delek Logistics incurs a loss, our operating results will reflect Delek Logistics' loss, net of intercompany eliminations, to the extent of our ownership interest in Delek Logistics.

Consolidation, Policy

All significant intercompany transactions and account balances have been eliminated in consolidation. All adjustments are of a normal, recurring nature.

Reclassification, Policy [Policy Text Block]

Certain prior period amounts have been reclassified in order to conform to the current year presentation.

Use of estimates policy

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

New Accounting Pronouncements, Policy [Policy Text Block]

New Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board ("FASB") issued guidance that requires organizations to use historical experience, current conditions, reasonable and supportable forecasts and forward-looking information in the measurement of all expected credit losses on financial instruments to more accurately estimate those losses. This guidance is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted after December 15, 2018, and interim periods within those fiscal years. We expect to adopt this guidance on or before the effective date and are currently evaluating the impact adopting this new guidance will have on our business, financial condition or results of operations.

In March 2016, the FASB issued guidance that simplifies several aspects of the accounting for share-based payment award transactions, including the accounting for excess tax benefits and deficiencies, classification of awards as either equity or liabilities and classification of excess tax benefits on the statement of cash flows. This guidance is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years and can be early adopted for any interim or annual financial statements that have not yet been issued. Early adoption is permitted. We expect to adopt this guidance on or before the effective date and are currently evaluating the impact adopting this new guidance will have on our business, financial condition or results of operations.

In February 2016, the FASB issued guidance that requires the recognition of a lease liability and a right-of-use asset, initially measured at the present value of the lease payments, in the statement of financial position for all leases previously accounted for as operating leases. This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. We expect to adopt this guidance on or before the effective date and are currently evaluating the impact adopting this new guidance will have on our business, financial condition or results of operations.

In February 2015, the FASB issued guidance that amends and simplifies the requirements for consolidation and provides additional guidance to reporting entities in evaluating whether certain legal entities, such as limited partnerships, limited liability corporations and securitization structures, should be consolidated. This guidance is effective for interim and annual periods beginning after December 15, 2015. We adopted this guidance on the effective date and the adoption did not have a material impact on our business, financial condition or results of operations.

Inventory [Abstract]

Inventory policy

Refinery inventory consists of crude oil, work-in-process, refined products and blendstocks which are stated at the lower of cost or market. Cost of inventory for the Tyler refinery is determined under the last-in, first- out ("LIFO") valuation method. Cost of inventory for the El Dorado refinery is determined on a first-in, first-out ("FIFO") basis. Cost of crude oil, refined product and feedstock inventories in excess of market value are charged to cost of goods sold.

Logistics inventory consists of refined products which are stated at the lower of FIFO cost or market.

Retail inventory consists of gasoline, diesel fuel, other petroleum products, cigarettes, beer, convenience merchandise and food service merchandise. Fuel inventories are stated at the lower of FIFO cost or market. Non-fuel inventories are stated at estimated cost as determined by the retail inventory method.

Segment Reporting [Abstract]

Segment Reporting, Policy [Policy Text Block]

We aggregate our operating units into three reportable segments: refining, logistics and retail. Our corporate activities, results of certain immaterial operating segments, our equity method investment in Alon USA and intercompany eliminations are reported in the corporate, other and eliminations segment. Decisions concerning the allocation of resources and assessment of operating performance are made based on this segmentation. Management measures the operating performance of each of the reportable segments based on the segment contribution margin.

Property, Plant and Equipment, Policy [Policy Text Block]

In accordance with ASC 360, Property, Plant & Equipment, Delek evaluates the realizability of property, plant and equipment as events occur that might indicate potential impairment.

Fair Value Measurements [Abstract]

Fair value of financial Instruments policy

ASC 820 requires disclosures that categorize assets and liabilities measured at fair value into one of three different levels depending on the observability of the inputs employed in the measurement. Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Level 2 inputs are observable inputs other than quoted prices included within Level 1 for the asset or liability, either directly or indirectly through market-corroborated inputs. Level 3 inputs are unobservable inputs for the asset or liability reflecting our assumptions about pricing by market participants.
