BRENTWOOD, Tenn.-- November 7, 2023 -- Delek US Holdings, Inc. (NYSE: DK) (“Delek US”, "Company") today announced financial results for its third quarter ended September 30, 2023.

"We achieved strong financial results in the third quarter by capturing favorable margins across our refining, logistics and retail businesses," said Avigal Soreq, President and Chief Executive Officer of Delek US. "Operating safely, reliably and in an environmentally responsible manner is our top priority. In the third quarter, we continued to build upon our solid foundation and drive results. In Refining, we ran well and achieved record total throughput. In Logistics, we are benefiting from our Permian location and investing in the continued growth of our business, which delivered record quarterly earnings once again. Our Retail business contributed the highest quarterly earnings since COVID."

“Financial strength and flexibility, as well as returning value to shareholders, remain key components of our strategy. During the quarter, we reduced debt by $175.6 million, we paid an increased dividend, and repurchased $25.0 million of stock. In the 4th quarter, the board of directors increased the quarterly dividend for the fifth consecutive quarter to $0.24 per share, and we repurchased an additional $20.0 million of stock. Year-to-date, we reduced debt by $415.7 million and returned $130.3 million of capital to shareholders through dividends and share repurchases,” Soreq continued.

"We remain focused on our long-term strategic objectives. We continued efforts to unlock value from our business and advanced our cost efficiency measures. In our operations, we have made progress at each refinery streamlining processes and improving reliability. We are well positioned to operate under mid-cycle market conditions,” Soreq concluded.

The refining segment Adjusted EBITDA was $285.5 million in the third quarter 2023 compared with $355.7 million in the same quarter last year, which reflects other inventory impacts of $(28.2) million and $279.5 million for third quarter 2023 and 2022, respectively. The decrease over 2022 is primarily due to lower refining crack spreads, partially offset by higher sales volume (including purchased product). During the third quarter 2023, Delek US's benchmark crack spreads were down an average of 8.2% from prior-year levels.

The logistics segment Adjusted EBITDA in the third quarter 2023 was $96.5 million compared with $91.5 million in the prior year quarter. The increase over last year's third quarter was driven by strong contributions from the Midland Gathering system and Delaware Gathering system in addition to annual rate increases.

For the third quarter 2023, Adjusted EBITDA for the retail segment was $16.2 million compared with $13.5 million in the prior-year period. The increase was primarily driven by increased average fuel margins and increased inside store margins.

Adjusted EBITDA from Corporate, Other and Eliminations was a loss of $(53.1) million in the third quarter 2023 compared with a loss of $(46.7) million in the prior-year period. The higher losses are driven by general and administrative costs, primarily related to employee benefit expenses.

On November 1, 2023, the Board of Directors approved the regular quarterly dividend of $0.240 per share that will be paid on November 20, 2023 to shareholders of record on November 13, 2023.

As of September 30, 2023, Delek US had a cash balance of $901.7 million and total consolidated long-term debt of $2,638.0 million, resulting in net debt of $1,736.3 million. As of September 30, 2023, Delek Logistics Partners, LP (NYSE: DKL) ("Delek Logistics") had $4.2 million of cash and $1,741.4 million of total long-term debt, which are included in the consolidated amounts on Delek US' balance sheet. Excluding Delek Logistics, Delek US had $897.5 million in cash and $896.6 million of long-term debt, or a $0.9 million net cash 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 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) and unrealized hedging (gain) loss;

•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.

(1) In the first quarter 2023, we reassessed the classification of certain expenses and made certain reclassification adjustments to better represent the nature of those expenses. Accordingly, we have made reclassifications to the prior period in order to conform to this revised current period classification, which resulted in a decrease in the prior period general and administrative expenses and an increase in the prior period operating expenses of approximately $3.1 million and $10.2 million for the three and nine months ended September 30, 2022.

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 third quarter 2023, we recorded restructuring costs totaling $3.5 million ($2.8 million after-tax) associated with our business transformation. These costs are recorded in general and administrative expenses in our consolidated statements of income and are reported in our Corporate segment.

"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 FIFO 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.

For the third quarter 2023, we recognized an additional $8.0 million ($6.2 million after-tax) for uncovered litigation, claims and assessments associated with the 2021 fire at the El Dorado refinery, which are included in operating expenses in the consolidated statements of income.
