STAR GROUP, L.P. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1) Organization

Star Group, L.P. (“Star,” the “Company,” “we,” “us,” or “our”) is a full service provider specializing in the sale of home heating and air conditioning products and services to residential and commercial home heating oil and propane customers. The Company has one reportable segment for accounting purposes. We also sell diesel fuel, gasoline and home heating oil on a delivery only basis. We believe we are the nation’s largest retail distributor of home heating oil based upon sales volume.

The Company is organized as follows:

•Star is a limited partnership, which at December 31, 2023, had outstanding 35.6 million Common Units (NYSE: “SGU”), representing a 99.1% limited partner interest in Star, and 0.3 million general partner units, representing a 0.9% general partner interest in Star. Our general partner is Kestrel Heat, LLC, a Delaware limited liability company (“Kestrel Heat” or the “general partner”). The Board of Directors of Kestrel Heat (the “Board”) is appointed by its sole member, Kestrel Energy Partners, LLC, a Delaware limited liability company (“Kestrel”). Although Star is a partnership, it is taxed as a corporation and its distributions to unitholders are treated as taxable dividends.

•Star owns 100% of Star Acquisitions, Inc. (“SA”), a Minnesota corporation that owns 100% of Petro Holdings, Inc. (“Petro”). SA and its subsidiaries are subject to Federal and state corporate income taxes. Star’s operations are conducted through Petro and its subsidiaries. Petro is primarily a Northeast and Mid-Atlantic U.S. region retail distributor of home heating oil and propane that at December 31, 2023 served approximately 404,800 full service residential and commercial home heating oil and propane customers and 57,600 customers on a delivery only basis. We also sell gasoline and diesel fuel to approximately 26,900 customers. We install, maintain, and repair heating and air conditioning equipment and to a lesser extent provide these services outside our heating oil and propane customer base including approximately 21,200 service contracts for natural gas and other heating systems.

•Petroleum Heat and Power Co., Inc. (“PH&P”) is a wholly owned subsidiary of Star. PH&P is the borrower and Star is the guarantor of the sixth amended and restated credit agreement’s $165 million five-year senior secured term loan and the $400 million ($550 million during the heating season of December through April of each year) revolving credit facility, both due July 6, 2027. (See Note 11—Long-Term Debt and Bank Facility Borrowings).

2) Summary of Significant Accounting Policies

Basis of Presentation

The Consolidated Financial Statements include the accounts of Star and its subsidiaries. All material intercompany items and transactions have been eliminated in consolidation.

The financial information included herein is unaudited; however, such information reflects all adjustments (consisting solely of normal recurring adjustments), which are, in the opinion of management, necessary for the fair statement of financial condition and results for the interim periods. Due to the seasonal nature of the Company’s business, the results of operations and cash flows for the three-month period ended December 31, 2023 are not necessarily indicative of the results to be expected for the full year.

These interim financial statements of the Company have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) for interim financial information and Rule 10-01 of Regulation S-X of the U.S. Securities and Exchange Commission (the “SEC”) and should be read in conjunction with the financial statements included in the Company’s Annual Report on Form 10-K for the year ended September 30, 2023.

Comprehensive Income

Comprehensive income is comprised of Net income and Other comprehensive income. Other comprehensive income consists of the unrealized gain on amortization on the Company’s pension plan obligation for its two frozen defined benefit pension plans, unrealized gain on available-for-sale investments, unrealized loss on interest rate hedges and the corresponding tax effects.

8

Cash, Cash Equivalents, and Restricted Cash

The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. At December 31, 2023, the $20.2 million of cash, cash equivalents, and restricted cash on the Condensed Consolidated Statements of Cash Flows is composed of $19.9 million of cash and cash equivalents and $0.3 million of restricted cash. At September 30, 2023, the $45.4 million of cash, cash equivalents, and restricted cash on the Condensed Consolidated Statements of Cash Flows is composed of $45.2 million of cash and cash equivalents and $0.3 million of restricted cash. Restricted cash represents deposits held by our captive insurance company that are required by state insurance regulations to remain in the captive insurance company as cash.

Fair Value Valuation Approach

The Company uses valuation approaches that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels:

•Level 1 inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date.

•Level 2 inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability.

•Level 3 inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date.

Captive Insurance Collateral

The captive insurance collateral is held by our captive insurance company in an irrevocable trust as collateral for certain workers’ compensation and automobile liability claims. The collateral is required by a third party insurance carrier that insures per claim amounts above a set deductible. If we did not deposit cash into the trust, the third party carrier would require that we issue an equal amount of letters of credit, which would reduce our availability under the sixth amended and restated credit agreement. Due to the expected timing of claim payments, the nature of the collateral agreement with the carrier, and our captive insurance company’s source of other operating cash, the collateral is not expected to be used to pay obligations within the next twelve months.

Unrealized gains and losses, net of related income taxes, are reported as accumulated other comprehensive income (loss), except for losses from impairments which are determined to be other-than-temporary. Realized gains and losses, and declines in value judged to be other-than-temporary on available-for-sale securities are included in the determination of net income and are included in Interest expense, net, at which time the average cost basis of these securities are adjusted to fair value.

Weather Hedge Contract

To partially mitigate the adverse effect of warm weather on cash flows, the Company has used weather hedge contracts for a number of years. Weather hedge contracts are recorded in accordance with the intrinsic value method defined by the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 815-45-15 Derivatives and Hedging, Weather Derivatives (EITF 99-2). The premium paid is included in the caption “Prepaid expenses and other current assets” in the accompanying balance sheets and amortized over the life of the contract, with the intrinsic value method applied at each interim period.

The Company entered into weather hedge contracts for fiscal years 2023 and 2024. The hedge period runs from November 1 through March 31, taken as a whole. The “Payment Thresholds,” or strikes, are set at various levels and are referenced against degree days for the prior ten year average. Under these contracts the maximum amount the Company can receive is $12.5 million annually. For the contracts applicable to fiscal 2023, we were additionally obligated to make an annual payment capped at $5.0 million if degree days exceeded the Payment Threshold. This obligation does not exist under the contract applicable to 2024.

In accordance with ASC 815-45, we recorded a $1.0 million benefit to delivery and branch expenses for the first quarter of fiscal 2024. The final settlement under this weather hedge contract for fiscal 2024 may differ depending on the actual degree-days recorded in the period January 1, 2024 through March 31, 2024. For the first quarter of fiscal 2023, we recorded an expense of $0.4 million which was subsequently reversed as the actual degree-days for the second quarter of fiscal 2023 were warmer than the Payment Thresholds and the Company recorded a benefit of $12.9 million in the second quarter of fiscal 2023.

New England Teamsters and Trucking Industry Pension Fund (“the NETTI Fund”) Liability

As of December 31, 2023, we had $0.3 million and $15.9 million balances included in the captions “Accrued expenses and other current liabilities” and “Other long-term liabilities,” respectively, on our Condensed Consolidated Balance Sheet representing the remaining balance of the NETTI Fund withdrawal liability. As of September 30, 2023, we had $0.3 million and $16.0 million balances reflected in these categories respectively. Based on the borrowing rates currently available to the Company for long-term financing of a similar maturity, the fair value of the NETTI Fund withdrawal liability as of December 31, 2023 and September 30, 2023 was $19.6 million and $18.5 million, respectively. We utilized Level 2 inputs in the fair value hierarchy of valuation techniques to determine the fair value of this liability.

Recently Adopted Accounting Pronouncements

In October 2021, the FASB issued ASU No. 2021-08, Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires accounting for contract assets and liabilities from contracts with customers in a business combination to be accounted for in accordance with ASC No. 606. The Company adopted the ASU effective October 1, 2023. The Company's adoption of the ASU did not have an impact on the Company's condensed consolidated financial statements and related disclosures.

Recently Issued Accounting Pronouncements

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to income tax disclosures, which requires that an entity, on an annual basis, disclose additional income tax information, primarily related to the rate reconciliation and income taxes paid. The standard is effective for fiscal years beginning after December 15, 2024. Adoption is either with a prospective method or a fully retrospective method of transition. Early adoption is permitted. The Company has not determined the timing of adoption and is currently evaluating the impact of the new standard on its condensed consolidated financial statements.

3) Revenue Recognition

The following disaggregates our revenue by major sources for the three months ended December 31, 2023 and December 31, 2022:

	Three Months Ended December 31,
(in thousands)	2023		2022
Petroleum Products:
Home heating oil and propane	$	351,214	$	435,523
Other petroleum products		97,336		134,406
Total petroleum products		448,550		569,929
Installations and Services:
Equipment installations		34,315		32,789
Equipment maintenance service contracts		28,916		28,716
Billable call services		16,315		16,753
Total installations and services		79,546		78,258
Total Sales	$	528,096	$	648,187

Deferred Contract Costs

We recognize an asset for incremental commission expenses paid to sales personnel in conjunction with obtaining new residential customer product and equipment maintenance service contracts. We defer these costs only when we have determined the commissions are, in fact, incremental and would not have been incurred absent the customer contract. Costs to obtain a contract are amortized and recorded ratably as delivery and branch expenses over the period representing the transfer of goods or services to which the assets relate. Costs to obtain new residential product and equipment maintenance service contracts are amortized as expense over the estimated customer relationship period of approximately five years. Deferred contract costs are classified as current or non-current within “Prepaid expenses and other current assets” and “Deferred charges and other assets, net,” respectively. At December 31, 2023, the amount of deferred contract costs included in “Prepaid expenses and other current assets” and “Deferred charges and other assets, net” was $3.3 million and $5.6 million, respectively. At September 30, 2023, the amount of deferred contract costs included in “Prepaid expenses and other current assets” and “Deferred charges and other assets, net” was $3.3 million and $5.4 million, respectively. For the three months ended December 31, 2023 and December 31, 2022 we recognized expense of $1.0 million

associated with the amortization of deferred contract costs within “Delivery and branch expenses” in the Condensed Consolidated Statement of Operations.

Contract Liability Balances

The Company has contract liabilities for advanced payments received from customers for future oil deliveries (primarily amounts received from customers on “smart pay” budget payment plans in advance of oil deliveries) and obligations to service customers with equipment maintenance service contracts. Contract liabilities are recognized straight-line over the service contract period, generally one year or less. As of December 31, 2023 and September 30, 2023 the Company had contract liabilities of $161.9 million and $170.3 million, respectively. During the three months ended December 31, 2023, the Company recognized $91.6 million of revenue that was included in the September 30, 2023 contract liability balance. During the three months ended December 31, 2022 the Company recognized $85.6 million of revenue that was included in the September 30, 2022 contract liability balance.

Receivables and Allowance for Doubtful Accounts

Accounts receivables from customers are recorded at the invoiced amounts. Finance charges may be applied to trade receivables that are more than 30 days past due, and are recorded as finance charge income.

The allowance for doubtful accounts is the Company’s estimate of the amount of trade receivables that may not be collectible. The allowance is determined at an aggregate level by grouping accounts based on certain account criteria and its receivable aging. The allowance is based on both quantitative and qualitative factors, including historical loss experience, historical collection patterns, overdue status, aging trends, current and future economic conditions. The Company has an established process to periodically review current and past due trade receivable balances to determine the adequacy of the allowance. No single statistic or measurement determines the adequacy of the allowance. The total allowance reflects management’s estimate of losses inherent in its trade receivables at the balance sheet date. Different assumptions or changes in economic conditions could result in material changes to the allowance for doubtful accounts.

Changes in the allowance for credit losses are as follows:

(in thousands)	Credit Loss Allowance
Balance at September 30, 2023	$	8,375
Current period provision		649
Write-offs, net and other		(950	)
Balance as of December 31, 2023	$	8,074

4) Common Unit Repurchase and Retirement

In July 2012, the Board adopted a plan to repurchase certain of the Company’s Common Units (the “Repurchase Plan”). Through May 2023, the Company had repurchased approximately 20.5 million Common Units under the Repurchase Plan. In May 2023, the Board authorized an increase of the number of Common Units that remained available for the Company to repurchase from 1.1 million to a total of 2.6 million, of which, approximately 2.3 million were available for repurchase in open market transactions and approximately 0.3 million were available for repurchase in privately-negotiated transactions. There is no guarantee of the number of units that will be purchased under the Repurchase Plan and the Company may discontinue purchases at any time. The Repurchase Plan does not have a time limit. The Board may also approve additional purchases of units from time to time in private transactions. The Company’s repurchase activities take into account SEC safe harbor rules and guidance for issuer repurchases. All of the Common Units purchased under the Repurchase Plan will be retired.

Under the Company’s sixth amended and restated credit agreement dated July 6, 2022, as amended, in order to pay distributions and repurchase Common Units, we must maintain Availability (as defined in the sixth amended and restated credit agreement) of $60 million, 15.0% of the facility size of $400 million (assuming no borrowings under the seasonal advance) on a historical pro forma and forward-looking basis, and a fixed charge coverage ratio of not less than 1.0 through February 27, 2024 and 1.15 thereafter measured as of the date of repurchase or distribution. (See Note 11—Long-Term Debt and Bank Facility Borrowings).

6) Derivatives and Hedging—Disclosures and Fair Value Measurements

The Company uses derivative instruments such as futures, options and swap agreements in order to mitigate exposure to market risk associated with the purchase of home heating oil for price-protected customers, physical inventory on hand, inventory in transit, priced purchase commitments and internal fuel usage. FASB ASC 815-10-05 Derivatives and Hedging, established accounting and reporting standards requiring that derivative instruments be recorded at fair value and included in the consolidated balance sheet as assets or liabilities, along with qualitative disclosures regarding the derivative activity. The Company has elected not to designate its commodity derivative instruments as hedging derivatives, but rather as economic hedges whose change in fair value is recognized in its statement of operations in the caption “(Increase) decrease in the fair value of derivative instruments.” Depending on the risk being economically hedged, realized gains and losses are recorded in cost of product, cost of installations and services, or delivery and branch expenses.

As of December 31, 2023, to hedge a substantial majority of the purchase price associated with heating oil gallons anticipated to be sold to its price-protected customers, the Company held the following derivative instruments that settle in future months to match anticipated sales: 14.2 million gallons of swap contracts, 8.8 million gallons of call options, 6.6 million gallons of put options, and 61.4 million net gallons of synthetic call options. To hedge its physical inventory on hand, inventory in transit and basis risk, the Company, as of December 31, 2023, held 0.2 million gallons of swap contracts and 20.7 million gallons of short future contracts that settle in future months. To hedge its internal fuel usage and other activities for fiscal 2024, the Company held 5.3 million gallons of swap contracts that settle in future months.

As of December 31, 2022, to hedge a substantial majority of the purchase price associated with heating oil gallons anticipated to be sold to its price-protected customers, the Company held the following derivative instruments that settle in future months to match anticipated sales: 9.4 million gallons of swap contracts, 23.2 million gallons of call options, 4.3 million gallons of put options, and 61.3 million net gallons of synthetic call options. To hedge its physical inventory on hand, inventory in transit and basis risk, the Company, as of December 31, 2022, held 25.3 million gallons of swap contracts and 7.3 million gallons of short future contracts that settle in future months. To hedge its internal fuel usage and other activities for fiscal 2023, the Company held 3.7 million gallons of swap contracts that settle in future months.

As of December 31, 2023, the Company has interest rate swap agreements in order to mitigate exposure to market risk associated with variable rate interest on $54.6 million, or 38%, of its long term debt. The Company has designated its interest rate swap agreements as cash flow hedging derivatives. To the extent these derivative instruments are effective and the accounting standard’s documentation requirements have been met, changes in fair value are recognized in other comprehensive income (loss) until the underlying hedged item is recognized in earnings. As of December 31, 2023 the fair value of the swap contracts was $0.6 million. As of September 30, 2023, the notional value of the swap contracts was $55.5 million and the fair value of the swap contracts was $1.6 million. We utilized Level 2 inputs in the fair value hierarchy of valuation techniques to determine the fair value of the swap contracts.

The Company’s derivative instruments are with the following counterparties: Bank of America, N.A., Bank of Montreal, Cargill, Inc., Citibank, N.A., JPMorgan Chase Bank, N.A., Key Bank, N.A. and Wells Fargo Bank, N.A. The Company assesses counterparty credit risk and considers it to be low. We maintain master netting arrangements that allow for the non-conditional offsetting of amounts receivable and payable with counterparties to help manage our risks and record derivative positions on a net basis. The Company generally does not receive cash collateral from its counterparties and does not restrict the use of cash collateral it maintains at counterparties. At December 31, 2023, the aggregate cash posted as collateral in the normal course of business at counterparties was $1.6 million and recorded in “Prepaid expense and other current assets.” Positions with counterparties who are also parties to our credit agreement are collateralized under that facility. As of December 31, 2023, $15.7 million hedge positions or payable amounts were secured under the credit facility.

The Company’s Level 1 derivative assets and liabilities represent the fair value of commodity contracts used in its hedging activities that are identical and traded in active markets. The Company’s Level 2 derivative assets and liabilities represent the fair value of commodity and interest rate contracts used in its hedging activities that are valued using either directly or indirectly observable inputs, whose nature, risk and class are similar. No significant transfers of assets or liabilities have been made into and out of the Level 1 or Level 2 tiers. All derivative instruments were non-trading positions and were either a Level 1 or Level 2 instrument. The Company had no Level 3 derivative instruments. The fair market value of our Level 1 and Level 2 derivative assets and liabilities are calculated by our counter-parties and are independently validated by the Company. The Company’s calculations are, for Level 1 derivative assets and liabilities, based on the published New York Mercantile Exchange (“NYMEX”) market prices for the commodity contracts open at the end of the period. For Level 2 derivative assets and liabilities the calculations performed by the Company are based on a combination of the NYMEX published market prices and other inputs, including such factors as present value, volatility and duration.

(b)Carrying amounts are net of unamortized debt issuance costs of $0.6 million as of December 31, 2023 and $0.7 million as of September 30, 2023.

On July 6, 2022, the Company refinanced its five-year term loan and the revolving credit facility with the execution of the sixth amended and restated revolving credit facility agreement (the “credit agreement”) with a bank syndicate comprised of ten participants, which enables the Company to borrow up to $400 million ($550 million during the heating season of December through April of each year) on a revolving credit facility for working capital purposes (subject to certain borrowing base limitations and coverage ratios), provides for a $165 million five-year senior secured term loan (“Term Loan”), allows for the issuance of up to $25 million in letters of credit, and has a maturity date of July 6, 2027.

The Company can increase the revolving credit facility size by an additional $200 million without the consent of the bank group. However, the bank group is not obligated to fund the $200 million increase. If the bank group elects not to fund the increase, the Company can add additional lenders to the group, with the consent of the Agent (as defined in the credit agreement), which shall not be unreasonably withheld. Obligations under the credit agreement are guaranteed by the Company and its subsidiaries and are secured by liens on substantially all of the Company’s assets, including accounts receivable, inventory, general intangibles, real property, fixtures and equipment.

All amounts outstanding under the sixth amended and restated revolving credit facility become due and payable on the facility termination date of July 6, 2027. The Term Loan is repayable in quarterly payments of $4.1 million, the first of which was made December 30, 2022, plus an annual payment equal to 25% of the annual Excess Cash Flow as defined in the credit agreement (an amount not to exceed $8.5 million annually), less certain voluntary prepayments made during the year, with final payment at maturity. In the first quarter of 2024 the Company repaid $4.0 million of additional loan repayments due to Excess Cash Flow related to fiscal 2023. There was no additional loan repayments due to Excess Cash Flow in the first quarter of fiscal 2023 related to fiscal 2022. The $4.1 million quarterly payment for the quarter ended December 31, 2023 was made on January 2, 2024.

The interest rate on the revolving credit facility and the term loan is based on a margin over Adjusted Term Secured Overnight Financing Rate ("SOFR") or a base rate. At December 31, 2023, the effective interest rate on the term loan (considering the impact of interest rate hedges) and revolving credit facility borrowings was approximately 7.4% and 8.6%, respectively, compared to 6.6% and 6.3%, respectively at September 30, 2023.

The commitment fee on the unused portion of the revolving credit facility is 0.30% from December through April, and 0.20% from May through November.

The credit agreement requires the Company to meet certain financial covenants, including a fixed charge coverage ratio (as defined in the credit agreement) of not less than 1.1 as long as the Term Loan is outstanding or revolving credit facility availability is less than 12.5% of the facility size. In addition, as long as the Term Loan is outstanding, a senior secured leverage ratio cannot be more than 3.0 as calculated as of the quarters ending June or September, and no more than 5.5 as calculated as of the quarters ending December or March.

On September 26, 2023, the Company signed a first amendment (the “Amendment”) to its Sixth Amended and Restated Credit Agreement with a group of banks, which provides temporary relief from certain financial covenants under the Credit Agreement that must be satisfied in order for the Company to make distributions and unit repurchases or, if availability under the Credit Agreement drops below a minimum threshold due to, among other things, the Company making acquisitions. In particular, the Amendment reduces the minimum fixed charge coverage ratio for distributions and unit repurchases during the period commencing October 31, 2023 and ending February 27, 2024 (the “Relief Period”) from 1.15-to-1.00 down to 1.00-to-1.00. The Amendment also reduces the minimum fixed charge coverage ratio that must be maintained by the Company if availability under the under the Credit Agreement drops below 12.5% of the facility size during the Relief Period from 1.10-to-1.00 down to 1.00-to-1.00. The Company’s fixed charge coverage ratio as of December 31, 2023 was 1.39 to 1.00.

Certain restrictions are also imposed by the sixth amended and restated credit agreement, including restrictions on the Company’s ability to incur additional indebtedness, to pay distributions to unitholders, to pay certain inter-company dividends or distributions, repurchase units, make investments, grant liens, sell assets, make acquisitions and engage in certain other activities.

At December 31, 2023, $144.5 million of the Term Loan was outstanding, $51.9 million was outstanding under the revolving credit facility, $15.7 million hedge positions were secured under the credit agreement, and $3.2 million of letters of credit were issued and outstanding. At September 30, 2023, $148.5 million of the term loan was outstanding, $0.2 million was outstanding under the revolving credit facility, $0.1 million hedge positions were secured under the credit agreement and $3.2 million of letters of credit were issued and outstanding.

At December 31, 2023, availability was $189.2 million, and the Company was in compliance with the financial covenants. At September 30, 2023, availability was $202.1 million, and the Company was in compliance with the financial covenants.

12) Income Taxes

The accompanying financial statements are reported on a fiscal year, however, the Company and its corporate subsidiaries file Federal and State income tax returns on a calendar year.

The current and deferred income tax expense for the three months ended December 31, 2023 and December 31, 2022 are as follows:

	Three Months Ended
	December 31,
(in thousands)	2023			2022
Income before income taxes	$	18,153		$	19,002
Current income tax expense		6,765			6,687
Deferred income tax expense (benefit)		(1,591	)		(1,224	)
Total income tax expense	$	5,174		$	5,463

At December 31, 2023, we did not have unrecognized income tax benefits.

Our continuing practice is to recognize interest and penalties related to income tax matters as a component of income tax expense. We file U.S. Federal income tax returns and various state and local returns. A number of years may elapse before an uncertain tax position is audited and finally resolved. For our Federal income tax returns we have four tax years subject to examination. In our major state tax jurisdictions of New York, Connecticut and Pennsylvania, we have four years that are subject to examination. In the state tax jurisdiction of New Jersey we have five tax years that are subject to examination. While it is often difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, based on our assessment of many factors, including past experience and interpretation of tax law, we believe that our provision for income taxes reflect the most probable outcome. This assessment relies on estimates and assumptions and may involve a series of complex judgments about future events.

14) Commitments and Contingencies

The Company’s operations are subject to the operating hazards and risks normally incidental to handling, storing and transporting and otherwise providing for use by consumers hazardous liquids such as home heating oil and propane. In the ordinary course of business, the Company is a defendant in various legal proceedings and litigation. The Company records a liability when it is probable that a loss has been incurred and the amount is reasonably estimable. We do not believe these matters, when considered individually or in the aggregate, could reasonably be expected to have a material adverse effect on the Company’s results of operations, financial position or liquidity.

The Company maintains insurance policies with insurers in amounts and with coverages and deductibles we believe are reasonable and prudent. However, the Company cannot assure that this insurance will be adequate to protect it from all material expenses related to current and potential future claims, legal proceedings and litigation, as certain types of claims may be excluded from our insurance coverage. If we incur substantial liability and the damages are not covered by insurance, or are in excess of policy limits, or if we incur liability at a time when we are not able to obtain liability insurance, then our business, results of operations and financial condition could be materially adversely affected.

* In any accounting period where the Company’s aggregate net income exceeds its aggregate distribution for such period, the Company is required to present net income per Limited Partner unit as if all of the earnings for the period were distributed, based on the terms of the Partnership agreement, regardless of whether those earnings would actually be distributed during a particular period from an economic or practical perspective. This allocation does not impact the Company’s overall net income or other financial results.

16) Subsequent Events

Quarterly Distribution Declared

In January 2024, we declared a quarterly distribution of $0.1625 per unit, or $0.65 per unit on an annualized basis, on all Common Units with respect to the first quarter of fiscal 2024, paid on January 31, 2024, to holders of record on January 22, 2024. The amount of distributions in excess of the minimum quarterly distribution of $0.0675 are distributed in accordance with our Partnership Agreement, subject to the management incentive compensation plan. As a result, $5.8 million was paid to the Common Unit holders, $0.3 million to the General Partner unit holders (including $0.3 million of incentive distribution as provided in our Partnership Agreement) and $0.3 million to management pursuant to the management incentive compensation plan which provides for certain members of management to receive incentive distributions that would otherwise be payable to the General Partner.

Acquisitions

Subsequent to December 31, 2023, the Company purchased the customer list and assets of one propane business and one heating oil business for an aggregate amount of approximately $19.9 million.

Liquid Product Price Volatility

Volatility, which is reflected in the wholesale price of liquid products, including home heating oil, propane and motor fuels, has a larger impact on our business when prices rise. Home heating oil consumers are sensitive to heating cost increases, and this often leads to customer conservation and increased gross customer losses. As a commodity, the price of home heating oil is generally impacted by many factors, including economic and geopolitical forces and is closely linked to the price of diesel fuel. The volatility in the wholesale cost of diesel fuel as measured by the New York Mercantile Exchange (“NYMEX”), for the fiscal years ending September 30, 2020, through 2024, on a quarterly basis, is illustrated in the following chart (price per gallon):

	Fiscal 2024				Fiscal 2023				Fiscal 2022				Fiscal 2021				Fiscal 2020

Income Taxes

Book versus Tax Deductions

The amount of cash flow generated in any given year depends upon a variety of factors including the amount of cash income taxes required, which will increase as depreciation and amortization decreases. The amount of depreciation and amortization that we deduct for book (i.e., financial reporting) purposes will differ from the amount that the Company can deduct for Federal tax purposes. The table below compares the estimated depreciation and amortization for book purposes to the amount that we expect to deduct for Federal tax purposes, based on currently owned assets. While we file our tax returns based on a calendar year, the amounts below are based on our September 30 fiscal year, and the tax amounts include any bonus depreciation available for fixed assets purchased. However, this table does not include any forecast of future annual capital purchases.

Estimated Depreciation and Amortization Expense

(In thousands) Fiscal Year	Book		Tax
2024	$	29,986	$	25,741
2025		24,386		22,580
2026		19,818		21,667
2027		17,650		19,781
2028		14,003		18,467
2029		12,026		15,818

Weather Hedge Contracts

Weather conditions have a significant impact on the demand for home heating oil and propane because certain customers depend on these products principally for space heating purposes. Actual weather conditions may vary substantially from year to year, significantly affecting the Company’s financial performance. To partially mitigate the adverse effect of warm weather on cash flow, we have used weather hedging contracts for a number of years with several providers.

The Company entered into weather hedge contracts for fiscal years 2023 and 2024. The hedge period runs from November 1 through March 31, taken as a whole. The “Payment Thresholds,” or strikes, are set at various levels and are referenced against degree days for the prior ten year average. Under these contracts the maximum amount the Company can receive is $12.5 million annually. For the contracts applicable to fiscal 2023, we were additionally obligated to make an annual payment capped at $5.0 million if degree days exceeded the Payment Threshold. This obligation does not exist under the contract applicable to 2024.

In accordance with ASC 815-45, we recorded a $1.0 million benefit to delivery and branch expenses for the first quarter of fiscal 2024. The final settlement under this weather hedge contract for fiscal 2024 may differ depending on the actual degree-days recorded in the period January 1, 2024 through March 31, 2024. For the first quarter of fiscal 2023, we recorded an expense of $0.4 million which was subsequently reversed as the actual degree-days for the second quarter of fiscal 2023 were warmer than the Payment Thresholds and the Company recorded a benefit of $12.9 million in the second quarter of fiscal 2023.

Per Gallon Gross Profit Margins

We believe home heating oil and propane margins should be evaluated on a cents per gallon basis before the effects of increases or decreases in the fair value of derivative instruments, as we believe that such per gallon margins are best at showing profit trends in the underlying business without the impact of non-cash changes in the market value of hedges before the settlement of the underlying transaction.

A significant portion of our home heating oil volume is sold to individual customers under an arrangement pre-establishing a ceiling price or fixed price for home heating oil over a set period of time, generally twelve to twenty-four months (“price-protected” customers). When these price-protected customers agree to purchase home heating oil from us for the next heating season, we purchase option contracts, swaps and futures contracts for a substantial majority of the heating oil that we expect to sell to these customers. The amount of home heating oil volume that we hedge per price-protected customer is based upon the estimated fuel consumption per average customer per month. In the event that the actual usage exceeds the amount of the hedged volume on a monthly basis, we may be required to obtain additional volume at unfavorable costs. In addition, should actual usage in any month be less than the hedged volume, our hedging costs and losses could be greater, thus reducing expected margins.

Derivatives

FASB ASC 815-10-05 Derivatives and Hedging requires that derivative instruments be recorded at fair value and included in the consolidated balance sheet as assets or liabilities. To the extent our interest rate derivative instruments designated as cash flow hedges are effective, as defined under this guidance, changes in fair value are recognized in other comprehensive income (loss) until the forecasted hedged item is recognized in earnings. We have elected not to designate our commodity derivative instruments as hedging instruments under this guidance and, as a result, the changes in fair value of the derivative instruments are recognized in our

21

statement of operations. Therefore, we experience volatility in earnings as outstanding derivative instruments are marked to market and non-cash gains and losses are recorded prior to the sale of the commodity to the customer. The volatility in any given period related to unrealized non-cash gains or losses on derivative instruments can be significant to our overall results. However, we ultimately expect those gains and losses to be offset by the cost of product when purchased.

Customer Attrition

We measure net customer attrition on an ongoing basis for our full service residential and commercial home heating oil and propane customers. Net customer attrition is the difference between gross customer losses and customers added through marketing efforts. Customers added through acquisitions are not included in the calculation of gross customer gains. However, additional customers that are obtained through marketing efforts or lost at newly acquired businesses are included in these calculations from the point of closing going forward. Customer attrition percentage calculations include customers added through acquisitions in the denominators of the calculations on a weighted average basis from the closing date. Gross customer losses are the result of a number of factors, including price competition, move-outs, credit losses, conversions to natural gas and service disruptions. When a customer moves out of an existing home, we count the “move out” as a loss, and, if we are successful in signing up the new homeowner, the “move in” is treated as a gain. The impact of certain geopolitical forces on liquid product prices could increase future attrition due to higher losses from credit related issues.

For the three months ended December 31, 2023, the Company lost 700 accounts (net), or 0.2% of its home heating oil and propane customer base, compared to 7,000 accounts gained (net), or 1.7% of its home heating and oil propane customer base in the prior year comparable period. Gross customer gains were 9,400 less than the prior year's comparable period primarily due to market conditions with regard to physical supply in the first quarter of fiscal 2023 that did not repeat in the current fiscal year, warmer weather and less customer move-ins. Gross customer losses were 1,700 less primarily due to reduction in number of customer relocations.

During the three months ended December 31, 2023, we estimate that we lost 0.4% of our home heating oil and propane accounts to natural gas and electricity conversions versus 0.4% for the three months ended December 31, 2022 and 0.4% for the three months ended December 31, 2021. Losses to natural gas and electricity in our footprint for the heating oil and propane industry could be greater or less than the Company’s estimates.

Acquisitions

The timing of acquisitions and the types of products sold by acquired companies impact year-over-year comparisons. During the three months ended December 31, 2023, the Company acquired two heating oil businesses for approximately $2.5 million and in February 2024 purchased the customer list and assets of one propane business and one heating oil business for an aggregate amount of

22

approximately $19.9 million. During fiscal 2023 the Company acquired one propane and two heating oil businesses for approximately $19.8 million. The following tables detail the Company’s acquisition activity and the associated volume sold during the 12-month period prior to the date of acquisition.

Sale of Certain Assets

In October 2022 we sold certain assets, which included a customer list of approximately 6,500 customers, for $2.7 million (including a deferred purchase price of $0.5 million). The following table details sales generated from the assets sold:

	Years Ended September 30,

Protected Price Account Renewals

A substantial majority of the Company’s price-protected customers have agreements with us that are subject to annual renewal in the period between April and November of each fiscal year. If a significant number of these customers elect not to renew their price-protected agreements with us and do not continue as our customers under a variable price-plan, the Company’s near term profitability, liquidity and cash flow will be adversely impacted.

Seasonality

The Company’s fiscal year ends on September 30. All references to quarters and years, respectively, in this document are to the fiscal quarters and fiscal years unless otherwise noted. The seasonal nature of our business has resulted, on average, during the last five years, in the sale of approximately 30% of the volume of home heating oil and propane in the first fiscal quarter and 50% of the volume in the second fiscal quarter, the peak heating season. Approximately 25% of the volume of motor fuel and other petroleum products is sold in each of the four fiscal quarters. We generally realize net income during the quarters ending December and March and net losses during the quarters ending June and September. In addition, sales volume typically fluctuates from year to year in response to variations in weather, wholesale energy prices and other factors.

Degree Day

A “degree day” is an industry measurement of temperature designed to evaluate energy demand and consumption. Degree days are based on how far the average daily temperature departs from 65°F. Each degree of temperature above 65°F is counted as one cooling degree day, and each degree of temperature below 65°F is counted as one heating degree day. Degree days are accumulated

23

each day over the course of a year and can be compared to a monthly or a long-term (multi-year) average to see if a month or a year was warmer or cooler than usual. Degree days are officially observed by the National Weather Service.

Every ten years, the National Oceanic and Atmospheric Administration (“NOAA”) computes and publishes average meteorological quantities, including the average temperature for the last 30 years by geographical location, and the corresponding degree days. The latest and most widely used data covers the years from 1991 to 2020. Our calculations of “normal” weather are based on these published 30 year averages for heating degree days, weighted by volume for the locations where we have existing operations.

Consolidated Results of Operations

The following is a discussion of the consolidated results of operations of the Company and its subsidiaries and should be read in conjunction with the historical financial and operating data and Notes thereto included elsewhere in this Quarterly Report.

24

Three Months Ended December 31, 2023

Compared to the Three Months Ended December 31, 2022

Volume

For the three months ended December 31, 2023, retail volume of home heating oil and propane sold decreased by 9.1 million gallons, or 10.2%, to 80.1 million gallons, compared to 89.2 million gallons for the three months ended December 31, 2022. For those locations where we had existing operations during both periods, which we sometimes refer to as the “base business” (i.e., excluding acquisitions), temperatures (measured on a heating degree day basis) for the three months ended December 31, 2023 were 9.6% warmer than the three months ended December 31, 2022 and 13.8% warmer than normal, as reported by NOAA. For the twelve months ended December 31, 2023, net customer attrition for the base business was 5.4%. The impact of fuel conservation, along with any period-to-period differences in delivery scheduling, the timing of accounts added or lost during the fiscal years, equipment efficiency, and other volume variances not otherwise described, are included in the chart below under the heading “Other.” An analysis of the change in the retail volume of home heating oil and propane, which is based on management’s estimates, sampling, and other mathematical calculations and certain assumptions, is found below:

(in millions of gallons)	Heating Oil and Propane
Volume - Three months ended December 31, 2022		89.2
Net customer attrition		(5.3	)
Impact of warmer temperatures		(8.5	)
Acquisitions		0.8
Sale of certain assets		(0.1	)
Other (a)		4.0
Change		(9.1	)
Volume - Three months ended December 31, 2023		80.1

(a) This favorable change may reverse in subsequent periods over the balance of 2024.

The following chart sets forth the percentage by volume of total home heating oil sold to residential variable-price customers, residential price-protected customers and commercial/industrial/other customers for the three months ended December 31, 2023, compared to the three months ended December 31, 2022:

	Three Months Ended
Customers	December 31, 2023			December 31, 2022
Residential Variable		42.1	%		42.7	%
Residential Price-Protected (Ceiling and Fixed Price)		43.8	%		43.9	%
Commercial/Industrial		14.1	%		13.4	%
Total		100.0	%		100.0	%

Volume of motor fuel and other petroleum products sold decreased by 3.2 million gallons, or 9.2%, to 32.4 million gallons for the three months ended December 31, 2023, compared to 35.6 million gallons for the three months ended December 31, 2022.

Product Sales

For the three months ended December 31, 2023, product sales decreased by $121.3 million, or 21.3%, to $448.6 million, compared to $569.9 million for the three months ended December 31, 2022, due to a decrease in total volume sold of 9.9% and a decrease in average selling prices. Selling prices decreased largely due to a decrease in wholesale product cost of $0.6605 per gallon, or 19.7%, compared to the three months ended December 31, 2022. Product volumes and wholesale product cost include heating oil, propane, motor fuels and other petroleum products.

Installations and Service

For the three months ended December 31, 2023, installation and service revenue increased by $1.2 million, or 1.6%, to $79.5 million, compared to $78.3 million for the three months ended December 31, 2022 driven by an increase in installation sales.

25

Cost of Product

For the three months ended December 31, 2023, cost of product decreased $115.8 million, or 27.6%, to $303.3 million, compared to $419.1 million for the three months ended December 31, 2022, due to a decrease in total volume sold of 9.9% and a decrease in wholesale product cost of $0.6605 per gallon, or 19.7%. Product volumes and wholesale product cost include heating oil, propane, motor fuels and other petroleum products.

Gross Profit — Product

The table below calculates our per gallon margins and reconciles product gross profit for home heating oil and propane and motor fuel and other petroleum products. We believe the change in home heating oil and propane margins should be evaluated before the effects of increases or decreases in the fair value of derivative instruments, as we believe that realized per gallon margins should not include the impact of non-cash changes in the market value of hedges before the settlement of the underlying transaction. On that basis, home heating oil and propane margins for the three months ended December 31, 2023 increased by $0.1306 per gallon, or 8.5%, to $1.6758 per gallon, from $1.5452 per gallon during the three months ended December 31, 2022. Going forward, we cannot assume that per gallon margins realized during the three months ended December 31, 2023 are sustainable especially with the volatility in heating oil and propane costs. Product sales and cost of product include home heating oil, propane, other petroleum products and liquidated damages billings.

	Three Months Ended

Sales	$	448.5	$	569.9
Cost	$	303.3	$	419.1
Gross Profit	$	145.2	$	150.8

For the three months ended December 31, 2023, total product gross profit was $145.2 million, which was $5.6 million, or 3.7%, lower than the three months ended December 31, 2022, due to a decrease in home heating oil and propane volume sold ($14.0 million) and decrease in gross profit from other petroleum products ($2.1 million), that was partially offset by an increase in home heating oil and propane margins ($10.5 million).

Cost of Installations and Service

Total installation costs for the three months ended December 31, 2023 increased by $0.8 million or 2.8%, to $27.5 million, compared to $26.7 million of installation costs for the three months ended December 31, 2022. This increase was largely due to higher installation sales. Installation costs as a percentage of installation sales were 80.1% for the three months ended December 31, 2023 and 81.6% for the three months ended December 31, 2022. Gross profit from installation increased by $0.8 million.

Service expense decreased by $2.2 million, or 4.4%, to $47.6 million for the three months ended December 31, 2023, representing 105.3% of service sales, versus $49.8 million, or 109.5% of service sales, for the three months ended December 31, 2022. The warmer temperatures drove a decrease in service calls and related expenses. In addition, a large proportion of our service expenses are incurred under fixed-fee prepaid service contract arrangements, therefore trends in service expenses may not directly correlate to trends in the related revenues. Gross loss from service decreased by $1.9 million.

26

We realized a combined gross profit from service and installation of $4.4 million for the three months ended December 31, 2023 compared to a gross profit of $1.7 million for the three months ended December 31, 2022, a $2.7 million increase.

(Increase) Decrease in the Fair Value of Derivative Instruments

During the three months ended December 31, 2023, the change in the fair value of derivative instruments resulted in a $19.0 million charge as a decrease in the market value for unexpired hedges (a $19.1 million charge) was partially offset by a $0.1 million credit due to the expiration of certain hedged positions.

During the three months ended December 31, 2022, the change in the fair value of derivative instruments resulted in a $17.6 million charge due to a decrease in the market value for unexpired hedges (a $9.6 million charge) and an $8.0 million charge due to the expiration of certain hedged positions.

Delivery and Branch Expenses

For the three months ended December 31, 2023, delivery and branch expense decreased $3.5 million, or 3.6%, to $94.4 million, compared to $97.9 million for the three months ended December 31, 2022. During the first quarter of fiscal 2024, the company recorded a benefit under the weather hedge of $1.0 million compared to a charge of $0.4 million in the prior year’s comparable quarter that accounts for a decrease in expense of $1.4 million. The decrease was also driven by a $2.9 million, or 9.0% reduction in delivery expenses due to the 10.2% decline in home heating oil and propane volume, a $1.0 million decrease in sales and marketing expenses due to a lower level of customer gains and related expenses, and $0.5 million of other net expense reductions. These decreases were partially offset by a $2.3 million increase in insurance expenses due to increasing premiums and expected claim costs.

Depreciation and Amortization Expenses

For the three months ended December 31, 2023, depreciation and amortization expenses increased $0.6 million, or 7.0%, to $8.4 million, compared to $7.8 million for the three months ended December 31, 2022, primarily due to acquisitions.

General and Administrative Expenses

For the three months ended December 31, 2023, general and administrative expenses increased by $0.1 million or 2.4%, to $7.0 million, from $6.9 million for the three months ended December 31, 2022, due to a $0.3 million increase in salaries and benefits expenses and $0.1 million of other net expense increases, that were partially offset by a $0.3 million decrease in profit sharing expense. The Company accrues approximately 6.0% of Adjusted EBITDA as defined in its profit sharing plan for distribution to its employees. This amount is payable when the Company achieves Adjusted EBITDA of at least 70% of the amount budgeted. The dollar amount of the profit sharing pool adjusts accordingly based on Adjusted EBITDA levels achieved.

Finance Charge Income

For the three months ended December 31, 2023, finance charge income decreased by $0.5 million or 41.5% to $0.8 million, from $1.3 million for the three months ended December 31, 2022, due to less late customer payment charges received on aged receivables.

Interest Expense, Net

For the three months ended December 31, 2023, net interest expense decreased by $1.1 million, or 24.7%, to $3.2 million compared to $4.3 million for the three months ended December 31, 2022. The year-over-year change was driven by a decrease in average borrowings of $87.7 million from $244.3 million for the three months ended December 31, 2022 to $156.6 million for the three months ended December 31, 2023 that was partially offset by an increase in the weighted average interest rate from 6.1% for the three months ended December 31, 2022 to 7.4% for the three months ended December 31, 2023. To hedge against rising interest rates, the Company utilizes interest rate swaps. At December 31, 2023, approximately 38% of borrowings under Star's variable-rate long term debt were not subject to interest rate increases as a result of interest rate swaps.

Amortization of Debt Issuance Costs

For the three months ended December 31, 2023, amortization of debt issuance cost was $0.3 million, essentially unchanged from the three months ended December 31, 2022.

27

Income Tax Expense

For the three months ended December 31, 2023, the Company’s income tax expense decreased by $0.3 million to $5.2 million, from $5.5 million for the three months ended December 31, 2022. The decrease in the income tax expense was driven by a $0.8 million decline in income before income taxes.

Net Income

For the three months ended December 31, 2023, Star’s net income decreased $0.6 million, to $13.0 million, compared to the three months ended December 31, 2022, primarily due to an unfavorable change in the fair value of derivative instruments of $1.4 million and a $0.6 million increase in depreciation and amortization expenses that was partially offset by a $1.1 million decrease in interest expense and a $0.3 million decrease in income tax expense.

Adjusted EBITDA

For the three months ended December 31, 2023, Adjusted EBITDA was $49.0 million, essentially unchanged from the three months ended December 31, 2022, as an increase in home heating oil and propane per gallon margins, an increase in service and installation profitability and lower operating costs offset a 9.1 million gallon decrease in home heating oil and propane volume sold.

EBITDA and Adjusted EBITDA should not be considered as an alternative to net income, as an indicator of operating performance, or as an alternative to cash flow, as a measure of liquidity or ability to service debt obligations, but provides additional information for evaluating the Company’s ability to make the Minimum Quarterly Distribution. EBITDA and Adjusted EBITDA are calculated as follows:

(a)EBITDA (Earnings from continuing operations before net interest expense, income taxes, depreciation and amortization) and Adjusted EBITDA (Earnings from continuing operations before net interest expense, income taxes, depreciation and amortization, (increase) decrease in the fair value of derivatives, other income (loss), net, multiemployer pension plan withdrawal charge, gain or loss on debt redemption, goodwill impairment, and other non-cash and non-operating charges) are non-GAAP financial measures that are used as supplemental financial measures by management and external users of our financial statements, such as investors, commercial banks and research analysts, to assess:

• our compliance with certain financial covenants included in our debt agreements;

• our financial performance without regard to financing methods, capital structure, income taxes or historical cost basis;

• our operating performance and return on invested capital compared to those of other companies in the retail distribution of refined petroleum products, without regard to financing methods and capital structure;

28

• our ability to generate cash sufficient to pay interest on our indebtedness and to make distributions to our partners; and

• the viability of acquisitions and capital expenditure projects and the overall rates of return of alternative investment opportunities.

The method of calculating Adjusted EBITDA may not be consistent with that of other companies, and EBITDA and Adjusted EBITDA both have limitations as analytical tools and so should not be viewed in isolation but in conjunction with measurements that are computed in accordance with GAAP. Some of the limitations of EBITDA and Adjusted EBITDA are:

• EBITDA and Adjusted EBITDA do not reflect our cash used for capital expenditures.

• Although depreciation and amortization are non-cash charges, the assets being depreciated or amortized often will have to be replaced and EBITDA and Adjusted EBITDA do not reflect the cash requirements for such replacements;

• EBITDA and Adjusted EBITDA do not reflect changes in, or cash requirements for, our working capital requirements;

• EBITDA and Adjusted EBITDA do not reflect the cash necessary to make payments of interest or principal on our indebtedness; and EBITDA and Adjusted EBITDA do not reflect the cash required to pay taxes.

29

DISCUSSION OF CASH FLOWS

We use the indirect method to prepare our Consolidated Statements of Cash Flows. Under this method, we reconcile net income to cash flows provided by operating activities by adjusting net income for those items that impact net income but do not result in actual cash receipts or payment during the period.

Operating Activities

Due to the seasonal nature of our business, cash is generally used in operations during the winter (our first and second fiscal quarters) as we require additional working capital to support the high volume of sales during this period, and cash is generally provided by operating activities during the spring and summer (our third and fourth fiscal quarters) when customer payments exceed the cost of deliveries.

During the three months ended December 31, 2023, cash used in operating activities decreased $32.4 million, to $60.3 million, compared to $92.7 million in cash used in operating activities during the three months ended December 31, 2022. The decrease was driven by an increase in collection of trade receivables on a comparable basis (including accounts receivable and customer credit balance accounts) of $34.4 million, a $10.0 million increase in collection of derivative settlement receivables on a comparative basis and a $1.9 million decrease in cash required to purchase liquid product inventory. Further, we paid $5.2 million less in payroll taxes in the first fiscal quarter of 2024 versus the first fiscal quarter of 2023 as the result of deferring payment of certain payroll tax withholdings in first quarter of fiscal 2021 to the first fiscal quarter of fiscal 2023. The increases were partially offset by an $11.3 million unfavorable change in accounts payable due to timing of inventory purchases, a $6.8 million increase in net cash paid for certain hedge positions, a $0.5 million decrease in cash flows from operations and $0.5 million of other net changes in working capital.

Investing Activities

During the three months ended December 31, 2023, the Company acquired two heating oil businesses for an aggregate price of approximately $2.5 million in cash. The gross purchase price was allocated $2.7 million to intangible assets, $0.2 million to goodwill, $0.8 million to fixed assets and reduced by $1.2 million of negative working capital.

Our capital expenditures for the three months ended December 31, 2023 totaled $3.2 million, as we invested in computer hardware and software ($0.3 million), refurbished certain physical plants ($0.9 million), expanded our propane operations ($0.4 million) and made additions to our fleet and other equipment ($1.6 million).

During the three months ended December 31, 2023, $0.4 million of earnings were reinvested into an irrevocable trust established in connection with our captive insurance company. The cash deposited into the trust is shown on our balance sheet as captive insurance collateral and, correspondingly, reduced cash on our balance sheet. We believe that investments into the irrevocable trust lower our letter of credit fees, increase interest income on invested cash balances, and provide us with certain tax advantages attributable to a captive insurance company.

During the three months ended December 31, 2022, the Company sold certain assets for cash proceeds of $2.2 million and acquired two heating oil businesses for an aggregate price of approximately $1.2 million in cash. The gross purchase price was allocated $1.7 million to intangible assets, $0.2 million to goodwill, $0.2 million to fixed assets and reduced by $0.9 million of negative working capital.

Our capital expenditures for the three months ended December 31, 2022 totaled $3.1 million, as we invested in computer hardware and software ($0.1 million), refurbished certain physical plants ($0.3 million), expanded our propane operations ($0.2 million) and made additions to our fleet and other equipment ($2.5 million).

During the three months ended December 31, 2022, $0.2 million of earnings were reinvested into the irrevocable trust.

Financing Activities

During the three months ended December 31, 2023, we repaid $4.0 million of our term loan, borrowed $51.6 million under our revolving credit facility, repurchased fewer than 0.1 million Common Units, at an average price paid of $11.27 per unit, for $0.2 million, in connection with our unit repurchase plan, and paid distributions of $5.8 million to our Common Unit holders and $0.3 million to our General Partner unit holders (including $0.3 million of incentive distributions as provided in our Partnership Agreement).

30

During the three months ended December 31, 2022, we repaid $4.1 million of our term loan, borrowed $116.3 million under our revolving credit facility, repurchased 0.4 million Common Units for $3.6 million, in connection with our unit repurchase plan, and paid distributions of $5.5 million to our Common Unit holders and $0.3 million to our General Partner unit holders (including $0.3 million of incentive distributions as provided in our Partnership Agreement).

FINANCING AND SOURCES OF LIQUIDITY

Liquidity and Capital Resources Comparatives

Our primary uses of liquidity are to provide funds for our working capital, capital expenditures, distributions on our units, acquisitions and unit repurchases. Our ability to provide funds for such uses depends on our future performance, which will be subject to prevailing economic, financial, geopolitical and business conditions, weather, the ability to collect current and future accounts receivable, the ability to pass on the full impact of high product costs to customers, the effects of high net customer attrition, conservation, inflation and other factors. Capital requirements, at least in the near term, are expected to be provided by cash flows from operating activities, cash on hand as of December 31, 2023 ($19.9 million) or a combination thereof. We believe that these cash sources will also be sufficient to satisfy our capital requirements in the longer-term. However, if they are not sufficient, we anticipate that working capital will be financed by our revolving credit facility, as discussed below, and from subsequent seasonal reductions in inventory and accounts receivable. As of December 31, 2023, we had accounts receivable of $187.1 million of which $139.8 million is due from residential customers and $47.3 million is due from commercial customers. Our ability to borrow from our bank group is based in part on the aging of these accounts receivable. If these balances do not meet the eligibility tests as defined in our sixth amended and restated credit agreement, our ability to borrow will be reduced and our anticipated cash flow from operating activities will also be reduced. As of December 31, 2023, we had $51.9 million of borrowings under our revolving credit facility, $144.5 million outstanding under our term loan, $3.2 million in letters of credit outstanding and $15.7 million hedge positions were secured under the credit agreement.

Under the terms of the sixth amended and restated credit agreement, as amended, we are required to maintain at all times a fixed charge coverage ratio of not less than 1.0 through February 27, 2024 and 1.15 thereafter if Availability (borrowing base less amounts borrowed and letters of credit issued) is less than 12.5% of the maximum facility size. We are also required to maintain a senior secured leverage ratio that cannot be more than 3.0 as of June 30th or September 30th, and no more than 5.5 as of December 31st or March 31st. As of December 31, 2023, Availability, as defined in the sixth amended and restated revolving credit facility agreement, as amended, was $189.2 million and we were in compliance with the financial covenants.

Maintenance capital expenditures for the remainder of fiscal 2024 are estimated to be approximately $9.0 million to $10.0 million, excluding the capital requirements for leased fleet. In addition, we plan to invest $1.0 million to $2.0 million in our propane operations. If, and only to the extent that, cash distributions to our unitholders remain at the current quarterly level of $0.1625 per unit for the balance of fiscal 2024, the Company would make aggregate payments of approximately $17.3 million to Common Unit holders, $1.0 million to our General Partner (including $0.9 million of incentive distribution as provided for in our Partnership Agreement) and $0.9 million to management pursuant to the management incentive compensation plan which provides for certain members of management to receive incentive distributions that would otherwise be payable to the General Partner. The amount of cash distributions payable to our unitholders, if any, depends on the amount of cash flow generated by the Company and our compliance with certain financial covenants under our sixth amended and restated revolving credit facility agreement. Under the terms of our sixth amended and restated revolving credit facility agreement, our term loan is repayable in quarterly payments of $4.1 million and we expect to pay $16.5 million for the remainder of fiscal 2024. Further, subject to any additional liquidity issues or concerns resulting from wholesale price volatility and our compliance with the financial covenants under our sixth amended and restated revolving credit facility agreement, we may repurchase Common Units pursuant to our unit repurchase plan, as amended from time to time, and seek attractive acquisition opportunities within the Availability constraints of our revolving credit facility and funding resources.

Contractual Obligations and Off-Balance Sheet Arrangements

There has been no material change to Contractual Obligations and Off-Balance Sheet Arrangements since our September 30, 2023 Form 10-K disclosure and therefore, the table has not been included in this Form 10-Q.

Recent Accounting Pronouncements

Refer to Note 2 – Summary of Significant Accounting Policies for discussion regarding the impact of accounting standards that were recently adopted and issued but not yet effective, on our consolidated financial statements.

Critical Accounting Policy and Critical Accounting Estimates

We believe that there have been no significant changes to our critical accounting policy and critical accounting estimates during the three months ended December 31, 2023 as compared to those we disclosed in Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our annual report on Form 10-K for the fiscal year ended September 30, 2023. While our critical accounting policies and estimates have not changed in any significant way during the three months ended December 31, 2023, the following provides disclosures about our critical accounting policy and critical accounting estimates.

Critical Accounting Policy

Fair Values of Derivatives

FASB ASC 815-10-05, Derivatives and Hedging, requires that derivative instruments be recorded at fair value and included in the consolidated balance sheet as assets or liabilities. The Company has elected not to designate its commodity derivative instruments as hedging instruments under this guidance, and therefore the change in fair value of those derivative instruments are recognized in our statement of operations.

We have established the fair value of our derivative instruments using estimates determined by our counterparties and subsequently evaluated them internally using established index prices and other sources. These values are based upon, among other things, futures prices, volatility, time-to-maturity value and credit risk. The estimate of fair value we report in our financial statements changes as these estimates are revised to reflect actual results, changes in market conditions, or other factors, many of which are beyond our control.

Critical Accounting Estimates

Self-Insurance Liabilities

We currently self-insure a portion of workers’ compensation, auto, general liability and medical claims. We establish and periodically evaluate self-insurance liabilities based upon expectations as to what our ultimate liability may be for outstanding claims using developmental factors based upon historical claim experience, including frequency, severity, demographic factors and other actuarial assumptions, supplemented with the support of a qualified third-party actuary. As of September 30, 2023, we had approximately $77.5 million of self-insurance liabilities. The ultimate resolution of these claims could differ materially from the assumptions used to calculate the self-insurance liabilities, which could have a material adverse effect on results of operations.

32

Item 3.

Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

We are exposed to interest rate risk primarily through our bank credit facilities. We utilize these borrowings to meet our working capital needs.

At December 31, 2023, we had outstanding borrowings totaling $196.4 million, of which $141.8 million are subject to variable interest rates under our credit agreement. In the event that interest rates associated with this facility were to increase 100 basis points, the after tax impact on annual future cash flows would be a decrease of $1.0 million.

Market Risk

We regularly use derivative financial instruments to manage our exposure to market risk related to changes in the current and future market price of home heating oil and vehicle fuels. The value of market sensitive derivative instruments is subject to change as a result of movements in market prices. Sensitivity analysis is a technique used to evaluate the impact of hypothetical market value changes. Based on a hypothetical ten percent increase in the cost of product at December 31, 2023, the potential impact on our hedging activity would be to increase the fair market value of these outstanding derivatives by $6.7 million to a fair market value of $(8.3) million; and conversely a hypothetical ten percent decrease in the cost of product would decrease the fair market value of these outstanding derivatives by $4.1 million to a fair market value of $(19.2) million.

Item 4.

Controls and Procedures

a) Evaluation of disclosure controls and procedures

The General Partner’s chief executive officer and chief financial officer evaluated the effectiveness of the Company’s disclosure controls and procedures (as that term is defined in Rule 13a-15(e) of the Securities Exchange Act of 1934, as amended) as of December 31, 2023. Based on that evaluation, such chief executive officer and chief financial officer concluded that the Company’s disclosure controls and procedures were effective as of December 31, 2023 at the reasonable level of assurance. For purposes of Rule 13a-15(e), the term disclosure controls and procedures means controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by the issuer in the reports that it files or submits under the Securities Exchange Act of 1934, as amended (the “Act”) (15 U.S.C. 78a et seq.) is recorded, processed, summarized and reported, within the time periods specified in the Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Act is accumulated and communicated to the issuer’s management, including its chief executive officer and chief financial officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

b) Change in internal control over financial reporting

No changes in the Company’s internal control over financial reporting occurred during the Company’s most recent fiscal quarter that has materially affected or is reasonably likely to materially affect the Company’s internal control over financial reporting.

c) Other

The General Partner and the Company believe that a controls system, no matter how well designed and operated, cannot provide absolute assurance that the objectives of the controls system are met, and no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a Company have been detected. Therefore, a control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Our disclosure controls and procedures are designed to provide such reasonable assurances of achieving our desired control objectives, and the chief executive officer and chief financial officer of the General Partner have concluded, as of December 31, 2023, that our disclosure controls and procedures were effective in achieving that level of reasonable assurance.

Accounting Policies [Abstract]

Organization

1) Organization

Star Group, L.P. (“Star,” the “Company,” “we,” “us,” or “our”) is a full service provider specializing in the sale of home heating and air conditioning products and services to residential and commercial home heating oil and propane customers. The Company has one reportable segment for accounting purposes. We also sell diesel fuel, gasoline and home heating oil on a delivery only basis. We believe we are the nation’s largest retail distributor of home heating oil based upon sales volume.

The Company is organized as follows:

•Star is a limited partnership, which at December 31, 2023, had outstanding 35.6 million Common Units (NYSE: “SGU”), representing a 99.1% limited partner interest in Star, and 0.3 million general partner units, representing a 0.9% general partner interest in Star. Our general partner is Kestrel Heat, LLC, a Delaware limited liability company (“Kestrel Heat” or the “general partner”). The Board of Directors of Kestrel Heat (the “Board”) is appointed by its sole member, Kestrel Energy Partners, LLC, a Delaware limited liability company (“Kestrel”). Although Star is a partnership, it is taxed as a corporation and its distributions to unitholders are treated as taxable dividends.

•Star owns 100% of Star Acquisitions, Inc. (“SA”), a Minnesota corporation that owns 100% of Petro Holdings, Inc. (“Petro”). SA and its subsidiaries are subject to Federal and state corporate income taxes. Star’s operations are conducted through Petro and its subsidiaries. Petro is primarily a Northeast and Mid-Atlantic U.S. region retail distributor of home heating oil and propane that at December 31, 2023 served approximately 404,800 full service residential and commercial home heating oil and propane customers and 57,600 customers on a delivery only basis. We also sell gasoline and diesel fuel to approximately 26,900 customers. We install, maintain, and repair heating and air conditioning equipment and to a lesser extent provide these services outside our heating oil and propane customer base including approximately 21,200 service contracts for natural gas and other heating systems.

•Petroleum Heat and Power Co., Inc. (“PH&P”) is a wholly owned subsidiary of Star. PH&P is the borrower and Star is the guarantor of the sixth amended and restated credit agreement’s $165 million five-year senior secured term loan and the $400 million ($550 million during the heating season of December through April of each year) revolving credit facility, both due July 6, 2027. (See Note 11—Long-Term Debt and Bank Facility Borrowings).

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

2) Summary of Significant Accounting Policies

Basis of Presentation

The Consolidated Financial Statements include the accounts of Star and its subsidiaries. All material intercompany items and transactions have been eliminated in consolidation.

The financial information included herein is unaudited; however, such information reflects all adjustments (consisting solely of normal recurring adjustments), which are, in the opinion of management, necessary for the fair statement of financial condition and results for the interim periods. Due to the seasonal nature of the Company’s business, the results of operations and cash flows for the three-month period ended December 31, 2023 are not necessarily indicative of the results to be expected for the full year.

These interim financial statements of the Company have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) for interim financial information and Rule 10-01 of Regulation S-X of the U.S. Securities and Exchange Commission (the “SEC”) and should be read in conjunction with the financial statements included in the Company’s Annual Report on Form 10-K for the year ended September 30, 2023.

Comprehensive Income

Comprehensive income is comprised of Net income and Other comprehensive income. Other comprehensive income consists of the unrealized gain on amortization on the Company’s pension plan obligation for its two frozen defined benefit pension plans, unrealized gain on available-for-sale investments, unrealized loss on interest rate hedges and the corresponding tax effects.

Cash, Cash Equivalents, and Restricted Cash

The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. At December 31, 2023, the $20.2 million of cash, cash equivalents, and restricted cash on the Condensed Consolidated Statements of Cash Flows is composed of $19.9 million of cash and cash equivalents and $0.3 million of restricted cash. At September 30, 2023, the $45.4 million of cash, cash equivalents, and restricted cash on the Condensed Consolidated Statements of Cash Flows is composed of $45.2 million of cash and cash equivalents and $0.3 million of restricted cash. Restricted cash represents deposits held by our captive insurance company that are required by state insurance regulations to remain in the captive insurance company as cash.

Fair Value Valuation Approach

The Company uses valuation approaches that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels:

•Level 1 inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date.

•Level 2 inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability.

•Level 3 inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date.

Captive Insurance Collateral

The captive insurance collateral is held by our captive insurance company in an irrevocable trust as collateral for certain workers’ compensation and automobile liability claims. The collateral is required by a third party insurance carrier that insures per claim amounts above a set deductible. If we did not deposit cash into the trust, the third party carrier would require that we issue an equal amount of letters of credit, which would reduce our availability under the sixth amended and restated credit agreement. Due to the expected timing of claim payments, the nature of the collateral agreement with the carrier, and our captive insurance company’s source of other operating cash, the collateral is not expected to be used to pay obligations within the next twelve months.

Unrealized gains and losses, net of related income taxes, are reported as accumulated other comprehensive income (loss), except for losses from impairments which are determined to be other-than-temporary. Realized gains and losses, and declines in value judged to be other-than-temporary on available-for-sale securities are included in the determination of net income and are included in Interest expense, net, at which time the average cost basis of these securities are adjusted to fair value.

Weather Hedge Contract

To partially mitigate the adverse effect of warm weather on cash flows, the Company has used weather hedge contracts for a number of years. Weather hedge contracts are recorded in accordance with the intrinsic value method defined by the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 815-45-15 Derivatives and Hedging, Weather Derivatives (EITF 99-2). The premium paid is included in the caption “Prepaid expenses and other current assets” in the accompanying balance sheets and amortized over the life of the contract, with the intrinsic value method applied at each interim period.

The Company entered into weather hedge contracts for fiscal years 2023 and 2024. The hedge period runs from November 1 through March 31, taken as a whole. The “Payment Thresholds,” or strikes, are set at various levels and are referenced against degree days for the prior ten year average. Under these contracts the maximum amount the Company can receive is $12.5 million annually. For the contracts applicable to fiscal 2023, we were additionally obligated to make an annual payment capped at $5.0 million if degree days exceeded the Payment Threshold. This obligation does not exist under the contract applicable to 2024.

In accordance with ASC 815-45, we recorded a $1.0 million benefit to delivery and branch expenses for the first quarter of fiscal 2024. The final settlement under this weather hedge contract for fiscal 2024 may differ depending on the actual degree-days recorded in the period January 1, 2024 through March 31, 2024. For the first quarter of fiscal 2023, we recorded an expense of $0.4 million which was subsequently reversed as the actual degree-days for the second quarter of fiscal 2023 were warmer than the Payment Thresholds and the Company recorded a benefit of $12.9 million in the second quarter of fiscal 2023.

New England Teamsters and Trucking Industry Pension Fund (“the NETTI Fund”) Liability

As of December 31, 2023, we had $0.3 million and $15.9 million balances included in the captions “Accrued expenses and other current liabilities” and “Other long-term liabilities,” respectively, on our Condensed Consolidated Balance Sheet representing the remaining balance of the NETTI Fund withdrawal liability. As of September 30, 2023, we had $0.3 million and $16.0 million balances reflected in these categories respectively. Based on the borrowing rates currently available to the Company for long-term financing of a similar maturity, the fair value of the NETTI Fund withdrawal liability as of December 31, 2023 and September 30, 2023 was $19.6 million and $18.5 million, respectively. We utilized Level 2 inputs in the fair value hierarchy of valuation techniques to determine the fair value of this liability.

Recently Adopted Accounting Pronouncements

In October 2021, the FASB issued ASU No. 2021-08, Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires accounting for contract assets and liabilities from contracts with customers in a business combination to be accounted for in accordance with ASC No. 606. The Company adopted the ASU effective October 1, 2023. The Company's adoption of the ASU did not have an impact on the Company's condensed consolidated financial statements and related disclosures.

Recently Issued Accounting Pronouncements

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to income tax disclosures, which requires that an entity, on an annual basis, disclose additional income tax information, primarily related to the rate reconciliation and income taxes paid. The standard is effective for fiscal years beginning after December 15, 2024. Adoption is either with a prospective method or a fully retrospective method of transition. Early adoption is permitted. The Company has not determined the timing of adoption and is currently evaluating the impact of the new standard on its condensed consolidated financial statements.

Deferred Contract Costs

We recognize an asset for incremental commission expenses paid to sales personnel in conjunction with obtaining new residential customer product and equipment maintenance service contracts. We defer these costs only when we have determined the commissions are, in fact, incremental and would not have been incurred absent the customer contract. Costs to obtain a contract are amortized and recorded ratably as delivery and branch expenses over the period representing the transfer of goods or services to which the assets relate. Costs to obtain new residential product and equipment maintenance service contracts are amortized as expense over the estimated customer relationship period of approximately five years. Deferred contract costs are classified as current or non-current within “Prepaid expenses and other current assets” and “Deferred charges and other assets, net,” respectively. At December 31, 2023, the amount of deferred contract costs included in “Prepaid expenses and other current assets” and “Deferred charges and other assets, net” was $3.3 million and $5.6 million, respectively. At September 30, 2023, the amount of deferred contract costs included in “Prepaid expenses and other current assets” and “Deferred charges and other assets, net” was $3.3 million and $5.4 million, respectively. For the three months ended December 31, 2023 and December 31, 2022 we recognized expense of $1.0 million

associated with the amortization of deferred contract costs within “Delivery and branch expenses” in the Condensed Consolidated Statement of Operations.

The Company has contract liabilities for advanced payments received from customers for future oil deliveries (primarily amounts received from customers on “smart pay” budget payment plans in advance of oil deliveries) and obligations to service customers with equipment maintenance service contracts. Contract liabilities are recognized straight-line over the service contract period, generally one year or less. As of December 31, 2023 and September 30, 2023 the Company had contract liabilities of $161.9 million and $170.3 million, respectively. During the three months ended December 31, 2023, the Company recognized $91.6 million of revenue that was included in the September 30, 2023 contract liability balance. During the three months ended December 31, 2022 the Company recognized $85.6 million of revenue that was included in the September 30, 2022 contract liability balance.

Receivables and Allowance for Doubtful Accounts

Accounts receivables from customers are recorded at the invoiced amounts. Finance charges may be applied to trade receivables that are more than 30 days past due, and are recorded as finance charge income.

The allowance for doubtful accounts is the Company’s estimate of the amount of trade receivables that may not be collectible. The allowance is determined at an aggregate level by grouping accounts based on certain account criteria and its receivable aging. The allowance is based on both quantitative and qualitative factors, including historical loss experience, historical collection patterns, overdue status, aging trends, current and future economic conditions. The Company has an established process to periodically review current and past due trade receivable balances to determine the adequacy of the allowance. No single statistic or measurement determines the adequacy of the allowance. The total allowance reflects management’s estimate of losses inherent in its trade receivables at the balance sheet date. Different assumptions or changes in economic conditions could result in material changes to the allowance for doubtful accounts.

Changes in the allowance for credit losses are as follows:

Common Unit Repurchase and Retirement

4) Common Unit Repurchase and Retirement

In July 2012, the Board adopted a plan to repurchase certain of the Company’s Common Units (the “Repurchase Plan”). Through May 2023, the Company had repurchased approximately 20.5 million Common Units under the Repurchase Plan. In May 2023, the Board authorized an increase of the number of Common Units that remained available for the Company to repurchase from 1.1 million to a total of 2.6 million, of which, approximately 2.3 million were available for repurchase in open market transactions and approximately 0.3 million were available for repurchase in privately-negotiated transactions. There is no guarantee of the number of units that will be purchased under the Repurchase Plan and the Company may discontinue purchases at any time. The Repurchase Plan does not have a time limit. The Board may also approve additional purchases of units from time to time in private transactions. The Company’s repurchase activities take into account SEC safe harbor rules and guidance for issuer repurchases. All of the Common Units purchased under the Repurchase Plan will be retired.

Under the Company’s sixth amended and restated credit agreement dated July 6, 2022, as amended, in order to pay distributions and repurchase Common Units, we must maintain Availability (as defined in the sixth amended and restated credit agreement) of $60 million, 15.0% of the facility size of $400 million (assuming no borrowings under the seasonal advance) on a historical pro forma and forward-looking basis, and a fixed charge coverage ratio of not less than 1.0 through February 27, 2024 and 1.15 thereafter measured as of the date of repurchase or distribution. (See Note 11—Long-Term Debt and Bank Facility Borrowings).

The following table shows repurchases under the Repurchase Plan:

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives and Hedging-Disclosures and Fair Value Measurements

6) Derivatives and Hedging—Disclosures and Fair Value Measurements

The Company uses derivative instruments such as futures, options and swap agreements in order to mitigate exposure to market risk associated with the purchase of home heating oil for price-protected customers, physical inventory on hand, inventory in transit, priced purchase commitments and internal fuel usage. FASB ASC 815-10-05 Derivatives and Hedging, established accounting and reporting standards requiring that derivative instruments be recorded at fair value and included in the consolidated balance sheet as assets or liabilities, along with qualitative disclosures regarding the derivative activity. The Company has elected not to designate its commodity derivative instruments as hedging derivatives, but rather as economic hedges whose change in fair value is recognized in its statement of operations in the caption “(Increase) decrease in the fair value of derivative instruments.” Depending on the risk being economically hedged, realized gains and losses are recorded in cost of product, cost of installations and services, or delivery and branch expenses.

As of December 31, 2023, to hedge a substantial majority of the purchase price associated with heating oil gallons anticipated to be sold to its price-protected customers, the Company held the following derivative instruments that settle in future months to match anticipated sales: 14.2 million gallons of swap contracts, 8.8 million gallons of call options, 6.6 million gallons of put options, and 61.4 million net gallons of synthetic call options. To hedge its physical inventory on hand, inventory in transit and basis risk, the Company, as of December 31, 2023, held 0.2 million gallons of swap contracts and 20.7 million gallons of short future contracts that settle in future months. To hedge its internal fuel usage and other activities for fiscal 2024, the Company held 5.3 million gallons of swap contracts that settle in future months.

As of December 31, 2022, to hedge a substantial majority of the purchase price associated with heating oil gallons anticipated to be sold to its price-protected customers, the Company held the following derivative instruments that settle in future months to match anticipated sales: 9.4 million gallons of swap contracts, 23.2 million gallons of call options, 4.3 million gallons of put options, and 61.3 million net gallons of synthetic call options. To hedge its physical inventory on hand, inventory in transit and basis risk, the Company, as of December 31, 2022, held 25.3 million gallons of swap contracts and 7.3 million gallons of short future contracts that settle in future months. To hedge its internal fuel usage and other activities for fiscal 2023, the Company held 3.7 million gallons of swap contracts that settle in future months.

As of December 31, 2023, the Company has interest rate swap agreements in order to mitigate exposure to market risk associated with variable rate interest on $54.6 million, or 38%, of its long term debt. The Company has designated its interest rate swap agreements as cash flow hedging derivatives. To the extent these derivative instruments are effective and the accounting standard’s documentation requirements have been met, changes in fair value are recognized in other comprehensive income (loss) until the underlying hedged item is recognized in earnings. As of December 31, 2023 the fair value of the swap contracts was $0.6 million. As of September 30, 2023, the notional value of the swap contracts was $55.5 million and the fair value of the swap contracts was $1.6 million. We utilized Level 2 inputs in the fair value hierarchy of valuation techniques to determine the fair value of the swap contracts.

The Company’s derivative instruments are with the following counterparties: Bank of America, N.A., Bank of Montreal, Cargill, Inc., Citibank, N.A., JPMorgan Chase Bank, N.A., Key Bank, N.A. and Wells Fargo Bank, N.A. The Company assesses counterparty credit risk and considers it to be low. We maintain master netting arrangements that allow for the non-conditional offsetting of amounts receivable and payable with counterparties to help manage our risks and record derivative positions on a net basis. The Company generally does not receive cash collateral from its counterparties and does not restrict the use of cash collateral it maintains at counterparties. At December 31, 2023, the aggregate cash posted as collateral in the normal course of business at counterparties was $1.6 million and recorded in “Prepaid expense and other current assets.” Positions with counterparties who are also parties to our credit agreement are collateralized under that facility. As of December 31, 2023, $15.7 million hedge positions or payable amounts were secured under the credit facility.

The Company’s Level 1 derivative assets and liabilities represent the fair value of commodity contracts used in its hedging activities that are identical and traded in active markets. The Company’s Level 2 derivative assets and liabilities represent the fair value of commodity and interest rate contracts used in its hedging activities that are valued using either directly or indirectly observable inputs, whose nature, risk and class are similar. No significant transfers of assets or liabilities have been made into and out of the Level 1 or Level 2 tiers. All derivative instruments were non-trading positions and were either a Level 1 or Level 2 instrument. The Company had no Level 3 derivative instruments. The fair market value of our Level 1 and Level 2 derivative assets and liabilities are calculated by our counter-parties and are independently validated by the Company. The Company’s calculations are, for Level 1 derivative assets and liabilities, based on the published New York Mercantile Exchange (“NYMEX”) market prices for the commodity contracts open at the end of the period. For Level 2 derivative assets and liabilities the calculations performed by the Company are based on a combination of the NYMEX published market prices and other inputs, including such factors as present value, volatility and duration.

The Company had no assets or liabilities that are measured at fair value on a nonrecurring basis subsequent to their initial recognition. The Company’s commodity financial assets and liabilities measured at fair value on a recurring basis are listed on the following table.

(b)Carrying amounts are net of unamortized debt issuance costs of $0.6 million as of December 31, 2023 and $0.7 million as of September 30, 2023.

On July 6, 2022, the Company refinanced its five-year term loan and the revolving credit facility with the execution of the sixth amended and restated revolving credit facility agreement (the “credit agreement”) with a bank syndicate comprised of ten participants, which enables the Company to borrow up to $400 million ($550 million during the heating season of December through April of each year) on a revolving credit facility for working capital purposes (subject to certain borrowing base limitations and coverage ratios), provides for a $165 million five-year senior secured term loan (“Term Loan”), allows for the issuance of up to $25 million in letters of credit, and has a maturity date of July 6, 2027.

The Company can increase the revolving credit facility size by an additional $200 million without the consent of the bank group. However, the bank group is not obligated to fund the $200 million increase. If the bank group elects not to fund the increase, the Company can add additional lenders to the group, with the consent of the Agent (as defined in the credit agreement), which shall not be unreasonably withheld. Obligations under the credit agreement are guaranteed by the Company and its subsidiaries and are secured by liens on substantially all of the Company’s assets, including accounts receivable, inventory, general intangibles, real property, fixtures and equipment.

All amounts outstanding under the sixth amended and restated revolving credit facility become due and payable on the facility termination date of July 6, 2027. The Term Loan is repayable in quarterly payments of $4.1 million, the first of which was made December 30, 2022, plus an annual payment equal to 25% of the annual Excess Cash Flow as defined in the credit agreement (an amount not to exceed $8.5 million annually), less certain voluntary prepayments made during the year, with final payment at maturity. In the first quarter of 2024 the Company repaid $4.0 million of additional loan repayments due to Excess Cash Flow related to fiscal 2023. There was no additional loan repayments due to Excess Cash Flow in the first quarter of fiscal 2023 related to fiscal 2022. The $4.1 million quarterly payment for the quarter ended December 31, 2023 was made on January 2, 2024.

The interest rate on the revolving credit facility and the term loan is based on a margin over Adjusted Term Secured Overnight Financing Rate ("SOFR") or a base rate. At December 31, 2023, the effective interest rate on the term loan (considering the impact of interest rate hedges) and revolving credit facility borrowings was approximately 7.4% and 8.6%, respectively, compared to 6.6% and 6.3%, respectively at September 30, 2023.

The commitment fee on the unused portion of the revolving credit facility is 0.30% from December through April, and 0.20% from May through November.

The credit agreement requires the Company to meet certain financial covenants, including a fixed charge coverage ratio (as defined in the credit agreement) of not less than 1.1 as long as the Term Loan is outstanding or revolving credit facility availability is less than 12.5% of the facility size. In addition, as long as the Term Loan is outstanding, a senior secured leverage ratio cannot be more than 3.0 as calculated as of the quarters ending June or September, and no more than 5.5 as calculated as of the quarters ending December or March.

On September 26, 2023, the Company signed a first amendment (the “Amendment”) to its Sixth Amended and Restated Credit Agreement with a group of banks, which provides temporary relief from certain financial covenants under the Credit Agreement that must be satisfied in order for the Company to make distributions and unit repurchases or, if availability under the Credit Agreement drops below a minimum threshold due to, among other things, the Company making acquisitions. In particular, the Amendment reduces the minimum fixed charge coverage ratio for distributions and unit repurchases during the period commencing October 31, 2023 and ending February 27, 2024 (the “Relief Period”) from 1.15-to-1.00 down to 1.00-to-1.00. The Amendment also reduces the minimum fixed charge coverage ratio that must be maintained by the Company if availability under the under the Credit Agreement drops below 12.5% of the facility size during the Relief Period from 1.10-to-1.00 down to 1.00-to-1.00. The Company’s fixed charge coverage ratio as of December 31, 2023 was 1.39 to 1.00.

Certain restrictions are also imposed by the sixth amended and restated credit agreement, including restrictions on the Company’s ability to incur additional indebtedness, to pay distributions to unitholders, to pay certain inter-company dividends or distributions, repurchase units, make investments, grant liens, sell assets, make acquisitions and engage in certain other activities.

At December 31, 2023, $144.5 million of the Term Loan was outstanding, $51.9 million was outstanding under the revolving credit facility, $15.7 million hedge positions were secured under the credit agreement, and $3.2 million of letters of credit were issued and outstanding. At September 30, 2023, $148.5 million of the term loan was outstanding, $0.2 million was outstanding under the revolving credit facility, $0.1 million hedge positions were secured under the credit agreement and $3.2 million of letters of credit were issued and outstanding.

At December 31, 2023, availability was $189.2 million, and the Company was in compliance with the financial covenants. At September 30, 2023, availability was $202.1 million, and the Company was in compliance with the financial covenants.

At December 31, 2023, we did not have unrecognized income tax benefits.

Our continuing practice is to recognize interest and penalties related to income tax matters as a component of income tax expense. We file U.S. Federal income tax returns and various state and local returns. A number of years may elapse before an uncertain tax position is audited and finally resolved. For our Federal income tax returns we have four tax years subject to examination. In our major state tax jurisdictions of New York, Connecticut and Pennsylvania, we have four years that are subject to examination. In the state tax jurisdiction of New Jersey we have five tax years that are subject to examination. While it is often difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, based on our assessment of many factors, including past experience and interpretation of tax law, we believe that our provision for income taxes reflect the most probable outcome. This assessment relies on estimates and assumptions and may involve a series of complex judgments about future events.

Commitments and Contingencies

14) Commitments and Contingencies

The Company’s operations are subject to the operating hazards and risks normally incidental to handling, storing and transporting and otherwise providing for use by consumers hazardous liquids such as home heating oil and propane. In the ordinary course of business, the Company is a defendant in various legal proceedings and litigation. The Company records a liability when it is probable that a loss has been incurred and the amount is reasonably estimable. We do not believe these matters, when considered individually or in the aggregate, could reasonably be expected to have a material adverse effect on the Company’s results of operations, financial position or liquidity.

The Company maintains insurance policies with insurers in amounts and with coverages and deductibles we believe are reasonable and prudent. However, the Company cannot assure that this insurance will be adequate to protect it from all material expenses related to current and potential future claims, legal proceedings and litigation, as certain types of claims may be excluded from our insurance coverage. If we incur substantial liability and the damages are not covered by insurance, or are in excess of policy limits, or if we incur liability at a time when we are not able to obtain liability insurance, then our business, results of operations and financial condition could be materially adversely affected.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The Consolidated Financial Statements include the accounts of Star and its subsidiaries. All material intercompany items and transactions have been eliminated in consolidation.

The financial information included herein is unaudited; however, such information reflects all adjustments (consisting solely of normal recurring adjustments), which are, in the opinion of management, necessary for the fair statement of financial condition and results for the interim periods. Due to the seasonal nature of the Company’s business, the results of operations and cash flows for the three-month period ended December 31, 2023 are not necessarily indicative of the results to be expected for the full year.

These interim financial statements of the Company have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) for interim financial information and Rule 10-01 of Regulation S-X of the U.S. Securities and Exchange Commission (the “SEC”) and should be read in conjunction with the financial statements included in the Company’s Annual Report on Form 10-K for the year ended September 30, 2023.

Comprehensive Income

Comprehensive Income

Comprehensive income is comprised of Net income and Other comprehensive income. Other comprehensive income consists of the unrealized gain on amortization on the Company’s pension plan obligation for its two frozen defined benefit pension plans, unrealized gain on available-for-sale investments, unrealized loss on interest rate hedges and the corresponding tax effects.

Cash, Cash Equivalents, and Restricted Cash

Cash, Cash Equivalents, and Restricted Cash

The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. At December 31, 2023, the $20.2 million of cash, cash equivalents, and restricted cash on the Condensed Consolidated Statements of Cash Flows is composed of $19.9 million of cash and cash equivalents and $0.3 million of restricted cash. At September 30, 2023, the $45.4 million of cash, cash equivalents, and restricted cash on the Condensed Consolidated Statements of Cash Flows is composed of $45.2 million of cash and cash equivalents and $0.3 million of restricted cash. Restricted cash represents deposits held by our captive insurance company that are required by state insurance regulations to remain in the captive insurance company as cash.

Fair Value Valuation Approach

Fair Value Valuation Approach

The Company uses valuation approaches that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels:

•Level 1 inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date.

•Level 2 inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability.

•Level 3 inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date.

Captive Insurance Collateral

Captive Insurance Collateral

The captive insurance collateral is held by our captive insurance company in an irrevocable trust as collateral for certain workers’ compensation and automobile liability claims. The collateral is required by a third party insurance carrier that insures per claim amounts above a set deductible. If we did not deposit cash into the trust, the third party carrier would require that we issue an equal amount of letters of credit, which would reduce our availability under the sixth amended and restated credit agreement. Due to the expected timing of claim payments, the nature of the collateral agreement with the carrier, and our captive insurance company’s source of other operating cash, the collateral is not expected to be used to pay obligations within the next twelve months.

Unrealized gains and losses, net of related income taxes, are reported as accumulated other comprehensive income (loss), except for losses from impairments which are determined to be other-than-temporary. Realized gains and losses, and declines in value judged to be other-than-temporary on available-for-sale securities are included in the determination of net income and are included in Interest expense, net, at which time the average cost basis of these securities are adjusted to fair value.

Weather Hedge Contract

Weather Hedge Contract

To partially mitigate the adverse effect of warm weather on cash flows, the Company has used weather hedge contracts for a number of years. Weather hedge contracts are recorded in accordance with the intrinsic value method defined by the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 815-45-15 Derivatives and Hedging, Weather Derivatives (EITF 99-2). The premium paid is included in the caption “Prepaid expenses and other current assets” in the accompanying balance sheets and amortized over the life of the contract, with the intrinsic value method applied at each interim period.

The Company entered into weather hedge contracts for fiscal years 2023 and 2024. The hedge period runs from November 1 through March 31, taken as a whole. The “Payment Thresholds,” or strikes, are set at various levels and are referenced against degree days for the prior ten year average. Under these contracts the maximum amount the Company can receive is $12.5 million annually. For the contracts applicable to fiscal 2023, we were additionally obligated to make an annual payment capped at $5.0 million if degree days exceeded the Payment Threshold. This obligation does not exist under the contract applicable to 2024.

In accordance with ASC 815-45, we recorded a $1.0 million benefit to delivery and branch expenses for the first quarter of fiscal 2024. The final settlement under this weather hedge contract for fiscal 2024 may differ depending on the actual degree-days recorded in the period January 1, 2024 through March 31, 2024. For the first quarter of fiscal 2023, we recorded an expense of $0.4 million which was subsequently reversed as the actual degree-days for the second quarter of fiscal 2023 were warmer than the Payment Thresholds and the Company recorded a benefit of $12.9 million in the second quarter of fiscal 2023.

New England Teamsters and Trucking Industry Pension Fund ("the NETTI Fund") Liability

New England Teamsters and Trucking Industry Pension Fund (“the NETTI Fund”) Liability

As of December 31, 2023, we had $0.3 million and $15.9 million balances included in the captions “Accrued expenses and other current liabilities” and “Other long-term liabilities,” respectively, on our Condensed Consolidated Balance Sheet representing the remaining balance of the NETTI Fund withdrawal liability. As of September 30, 2023, we had $0.3 million and $16.0 million balances reflected in these categories respectively. Based on the borrowing rates currently available to the Company for long-term financing of a similar maturity, the fair value of the NETTI Fund withdrawal liability as of December 31, 2023 and September 30, 2023 was $19.6 million and $18.5 million, respectively. We utilized Level 2 inputs in the fair value hierarchy of valuation techniques to determine the fair value of this liability.

Recently Adopted Accounting Pronouncements

Recently Adopted Accounting Pronouncements

In October 2021, the FASB issued ASU No. 2021-08, Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires accounting for contract assets and liabilities from contracts with customers in a business combination to be accounted for in accordance with ASC No. 606. The Company adopted the ASU effective October 1, 2023. The Company's adoption of the ASU did not have an impact on the Company's condensed consolidated financial statements and related disclosures.

Recently Issued Accounting Pronouncements

Recently Issued Accounting Pronouncements

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to income tax disclosures, which requires that an entity, on an annual basis, disclose additional income tax information, primarily related to the rate reconciliation and income taxes paid. The standard is effective for fiscal years beginning after December 15, 2024. Adoption is either with a prospective method or a fully retrospective method of transition. Early adoption is permitted. The Company has not determined the timing of adoption and is currently evaluating the impact of the new standard on its condensed consolidated financial statements.

Deferred Contract Costs

Deferred Contract Costs

We recognize an asset for incremental commission expenses paid to sales personnel in conjunction with obtaining new residential customer product and equipment maintenance service contracts. We defer these costs only when we have determined the commissions are, in fact, incremental and would not have been incurred absent the customer contract. Costs to obtain a contract are amortized and recorded ratably as delivery and branch expenses over the period representing the transfer of goods or services to which the assets relate. Costs to obtain new residential product and equipment maintenance service contracts are amortized as expense over the estimated customer relationship period of approximately five years.

Receivables and Allowance for Doubtful Accounts

Receivables and Allowance for Doubtful Accounts

Accounts receivables from customers are recorded at the invoiced amounts. Finance charges may be applied to trade receivables that are more than 30 days past due, and are recorded as finance charge income.

The allowance for doubtful accounts is the Company’s estimate of the amount of trade receivables that may not be collectible. The allowance is determined at an aggregate level by grouping accounts based on certain account criteria and its receivable aging. The allowance is based on both quantitative and qualitative factors, including historical loss experience, historical collection patterns, overdue status, aging trends, current and future economic conditions. The Company has an established process to periodically review current and past due trade receivable balances to determine the adequacy of the allowance. No single statistic or measurement determines the adequacy of the allowance. The total allowance reflects management’s estimate of losses inherent in its trade receivables at the balance sheet date. Different assumptions or changes in economic conditions could result in material changes to the allowance for doubtful accounts.

Derivatives and Hedging

The Company uses derivative instruments such as futures, options and swap agreements in order to mitigate exposure to market risk associated with the purchase of home heating oil for price-protected customers, physical inventory on hand, inventory in transit, priced purchase commitments and internal fuel usage. FASB ASC 815-10-05 Derivatives and Hedging, established accounting and reporting standards requiring that derivative instruments be recorded at fair value and included in the consolidated balance sheet as assets or liabilities, along with qualitative disclosures regarding the derivative activity. The Company has elected not to designate its commodity derivative instruments as hedging derivatives, but rather as economic hedges whose change in fair value is recognized in its statement of operations in the caption “(Increase) decrease in the fair value of derivative instruments.” Depending on the risk being economically hedged, realized gains and losses are recorded in cost of product, cost of installations and services, or delivery and branch expenses.
