BRENTWOOD, Tenn.-- August 6, 2025 -- Delek US Holdings, Inc. (NYSE: DK) (“Delek US”, "Company") today announced financial results for its second quarter ended June 30, 2025.

“We continue to make progress in achieving our Sum of the Parts goals and improving the overall profitability of the company by achieving our original $120 million EOP target one quarter in advance,” said Avigal Soreq, President and Chief Executive Officer of Delek US. “Our EOP efforts are exceeding expectations and today we have increased our run-rate cash flow improvement target to $130 to 170 million. DKL's processing plant further strengthens DKL's premier position in the Permian basin. The new processing plant, ongoing AGI initiatives, and DKL's increasing economic separation from DK are getting us closer to unlocking the full value of our midstream assets."

"Looking ahead, we will continue to execute on our priorities of running safe and reliable operations, making further progress on midstream deconsolidation, improving cash flow generation, and delivering shareholder value while maintaining our financial strength and flexibility," Soreq concluded.

The refining segment Adjusted EBITDA was $113.6 million in the second quarter 2025 compared with $42.1 million in the same quarter last year, which reflects other inventory impacts of $41.9 million and $14.6 million for second quarter 2025 and 2024, respectively. The increase over 2024 is primarily due to an increase in refining margin driven by increased crack spreads. During the second quarter 2025, Delek US's benchmark crack spreads were up an average of 11.4% from prior-year levels.

The logistics segment Adjusted EBITDA in the second quarter 2025 was $120.2 million compared with $100.6 million in the prior-year quarter. The increase over last year's second quarter was driven by the impact of the W2W dropdown and incremental contribution due to the H2O Midstream Acquisition on September 11, 2024, the Gravity Acquisition on January 2, 2025, and the increase in wholesale margins.

On July 30, 2025, the Board of Directors approved the regular quarterly dividend of $0.255 per share that will be paid on August 18, 2025 to shareholders of record on August 11, 2025.

As of June 30, 2025, Delek US had a cash balance of $615.5 million and total consolidated long-term debt of $3,100.7 million, resulting in net debt of $2,485.2 million. As of June 30, 2025, Delek Logistics Partners, LP (NYSE: DKL) ("Delek Logistics") had $1.4 million of cash and $2,211.4 million of total long-term debt, which are included in the consolidated amounts on Delek US' balance sheet. Excluding Delek Logistics, Delek US had $614.1 million in cash and $889.3 million of long-term debt, or a $275.2 million net debt position.

Our management uses certain “non-GAAP” operational measures to evaluate our operating segment performance and non-GAAP financial measures to evaluate past performance and prospects for the future to supplement our financial information presented in accordance with United States ("U.S.") Generally Accepted Accounting Principles ("GAAP"). These financial and operational non-GAAP measures are important factors in assessing our operating results and profitability and include:

•Adjusting items - certain identified infrequently occurring items, non-cash items, and items that are not attributable to or indicative of our on-going operations or that may obscure our underlying results and trends;

•Adjusted net income (loss) - calculated as net income (loss) attributable to Delek US adjusted for relevant Adjusting items recorded during the period;

•Adjusted net income (loss) per share - calculated as Adjusted net income (loss) divided by weighted average shares outstanding, assuming dilution, as adjusted for any anti-dilutive instruments that may not be permitted for consideration in GAAP earnings per share calculations but that nonetheless favorably impact dilution;

•Earnings before interest, taxes, depreciation and amortization ("EBITDA") - calculated as net income (loss) attributable to Delek US adjusted to add back interest expense, income tax expense, depreciation and amortization;

•Adjusted EBITDA - calculated as EBITDA adjusted for the relevant identified Adjusting items in Adjusted net income (loss) that do not relate to interest expense, income tax expense, depreciation or amortization, and adjusted to include income (loss) attributable to non-controlling interests;

•Refining margin - calculated as gross margin (which we define as sales minus cost of sales) adjusted for operating expenses and depreciation and amortization included in cost of sales;

•Adjusted refining margin - calculated as refining margin adjusted for other inventory impacts, net inventory LCM valuation loss (benefit), unrealized hedging (gain) loss and intercompany lease impacts;

•Refining production margin - calculated based on the regional market sales price of refined products produced, less allocated transportation, Renewable Fuel Standard volume obligation and associated feedstock costs. This measure reflects the economics of each refinery exclusive of the financial impact of inventory price risk mitigation programs and marketing uplift strategies;

•Refining production margin per throughput barrel - calculated as refining production margin divided by our average refining throughput in barrels per day (excluding purchased barrels) multiplied by 1,000 and multiplied by the number of days in the period; and

•Net debt - calculated as long-term debt including both current and non-current portions (the most comparable GAAP measure) less cash and cash equivalents as of a specific balance sheet date.

We believe these non-GAAP operational and financial measures are useful to investors, lenders, ratings agencies and analysts to assess our ongoing performance because, when reconciled to their most comparable GAAP financial measure, they provide improved relevant comparability between periods, to peers or to market metrics through the inclusion of retroactive regulatory or other adjustments as if they had occurred in the prior periods they relate to, or through the exclusion of certain items that we believe are not indicative of our core operating performance and that may obscure our underlying results and trends. “Net debt,” also a non-GAAP financial measure, is an important measure to monitor leverage and evaluate the balance sheet.

Non-GAAP measures have important limitations as analytical tools, because they exclude some, but not all, items that affect net earnings and operating income. These measures should not be considered substitutes for their most directly comparable U.S. GAAP financial measures. Additionally, because Adjusted net income or loss, Adjusted net income or loss per share, EBITDA and Adjusted EBITDA, Adjusted Refining Margin and Refining Production Margin or any of our other identified non-GAAP measures may be defined differently by other companies in its industry, Delek US' definition may not be comparable to similarly titled measures of other companies. See the accompanying tables in this earnings release for a reconciliation of these non-GAAP measures to the most directly comparable GAAP measures.

We review investments held at cost quarterly for indicators of impairment. During the three months ended June 30, 2025, we recorded an $8.6 million ($6.7 million, after-tax) of impairment in connection to two investments held at cost.

We incurred $3.9 million ($3.0 million after-tax) of additional transaction related costs in connection with the previously announced acquisition of interests in H2O Midstream Intermediate, LLC, H2O Midstream Permian LLC, and H2O Midstream LLC (the "H2O Midstream Acquisition"), intercompany agreement amendments and acquisition of interests in Gravity Water Intermediate Holdings LLC ("Gravity Acquisition") during the three months ended June 30, 2025.

In 2022, we announced that we are progressing a business transformation focused on enterprise-wide opportunities to improve the efficiency of our cost structure. For the second quarter 2025, we recorded restructuring costs totaling $25.5 million ($19.8 million after-tax) associated with our business transformation. Restructuring costs of $22.1 million are recorded in general and administrative expenses and $3.4 million are included in operating expenses in our condensed consolidated statements of income.

Excluding transaction costs and restructuring costs, general and administrative expenses were $50.5 million for the three months ended June 30, 2025.

On May 1, 2025, we transferred the Delek Permian Gathering ("DPG") purchasing and blending activities to Delek Logistics (the "DPG Dropdown”). The operating results of DPG are now reported in our Logistics segment, while previously recorded in the Refining segment. The dropdown has no impact to Delek US consolidated results as these amounts eliminate in consolidation.

"Other inventory impact" is primarily calculated by multiplying the number of barrels sold during the period by the difference between current period weighted average purchase cost per barrel directly related to our refineries and per barrel cost of materials and other for the period recognized on a first-in, first-out basis directly related to our refineries. It assumes no beginning or ending inventory, so that the current period average purchase cost per barrel is a reasonable estimate of our market purchase cost for the current period, without giving effect to any build or draw on beginning inventory. These amounts are based on management estimates using a methodology including these assumptions. However, this analysis provides management with a means to compare hypothetical refining margins to current period average crack spreads, as well as provides a means to better compare our results to peers.

As a result of amendments to intercompany lease agreements in August 2024, we had to reassess lease classification for the agreements that contain leases under Accounting Standards Codification 842. As a result of these lease assessments, certain of these agreements met the criteria to be accounted for as sales-type leases for Delek Logistics and finance leases for the Refining segment. Therefore, portions of the minimum volume commitments under these agreements subject to sales-type lease accounting are recorded as interest income with the remaining amounts recorded as a reduction in net investment in leases. Prior to the amendments, these agreements were accounted for as operating leases and these minimum volume commitments were recorded as revenues in the Logistics segment. Similarly, these minimum volume commitments were previously recorded as costs of sales for the Refining segment, as the underlying lease was reclassified from an operating lease to a finance lease, and these payments are now recorded as interest expense and reductions in the lease liability. These accounting changes have no impact to the Delek US consolidated results as these amounts eliminate in consolidation.
