Adjusted EBITDA	$ 60.6	$ 209.8	$ 949.7	$ 1,169.8

Refining Segment

The refining segment Adjusted EBITDA was $(10.4) million in the fourth quarter 2023 compared with $170.9 million in the same quarter last year, which reflects other inventory impacts of $48.6 million and $193.6 million for fourth quarter 2023 and 2022, respectively. The decrease over 2022 is primarily due to lower refining crack spreads, partially offset by higher sales volume. During the fourth quarter 2023, Delek US's benchmark crack spreads were down an average of 50.7% from prior-year levels.

Logistics Segment

The logistics segment Adjusted EBITDA in the fourth quarter 2023 was $99.4 million compared with $90.6 million in the prior year quarter. The increase over last year's fourth quarter was driven by strong contributions from the Midland Gathering and Delaware Gathering systems in addition to annual rate increases.

Retail Segment

For the fourth quarter 2023, Adjusted EBITDA for the retail segment was $9.3 million compared with $7.8 million in the prior-year period. The increase was primarily driven by higher inside store margins and total retail fuel gallons sold.

Corporate and Other Activity

Adjusted EBITDA from Corporate, Other and Eliminations was a loss of $(37.7) million in the fourth quarter 2023 compared with a loss of $(59.5) million in the prior-year period. The improvement was driven by lower general and administrative costs, primarily related to employee benefit expenses.

Shareholder Distributions

On February 20, 2024, the Board of Directors approved the regular quarterly dividend of $0.245 per share that will be paid on March 8, 2024 to shareholders of record on March 1, 2024.

Liquidity

As of December 31, 2023, Delek US had a cash balance of $822.2 million and total consolidated long-term debt of $2,599.8 million, resulting in net debt of $1,777.6 million. As of December 31, 2023, Delek Logistics Partners, LP (NYSE: DKL) ("Delek Logistics") had $3.8 million of cash and $1,703.8 million of total long-term debt, which are included in the consolidated amounts on Delek US' balance sheet. Excluding Delek Logistics, Delek US had $818.4 million in cash and $896.0 million of long-term debt, or a $77.6 million net debt position.

Capital Program

The Delek US 2024 Capital Program is forecasted to be approximately $330 million, with $255 million for sustaining and regulatory capital and $75 million for growth capital. The 2024 Capital Program compares with the 2023 Capital Program of $372 million, which includes $17 million of insurance proceeds, growth capital partially funded by producers, as well as other reimbursements. Excluding these proceeds, 2023 capital expenditures were $389 million.

For 2024, in the Refining segment, Delek US plans to invest $220 million, with 93% of the capital dedicated towards sustaining and regulatory projects and 7% for projects focused on improving the efficiency and yield of Delek refineries. Most of Refining's capital expenditures are for the Krotz Spring Refinery major turnaround scheduled during the fourth quarter of 2024, as well as projects at Big Spring Refinery to improve capture rates.

In the Logistics segment, the company expects the capital program to be approximately $70 million. This includes approximately $20 million of sustaining and regulatory capital, and $50 million of growth capital. Growth capital is to advance new connections in both the Midland and Delaware gathering systems, enabling continued volume growth at the partnership.

The Retail segment capital expenditures are expected to be approximately $15 million. Funds are dedicated to maintaining Delek's 250 convenience stores, including interior rebranding and reimaging initiatives.

Non-GAAP Disclosures:

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) 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.

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 $6.1 million and $16.3 million for the three and twelve months ended December 31, 2022, respectively.

Significant Transactions During the Quarter Impacting Results:

Restructuring Costs

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 fourth quarter 2023, we recorded restructuring costs totaling $31.4 million ($24.3 million after-tax) associated with our business transformation. The fourth quarter 2023 included a $23.1 million impairment related to leased crude oil tanks in Canada that were not needed to support the future growth of our business. Restructuring costs of $23.1 million are recorded in asset impairment, $7.1 million are recorded in general and administrative expenses and $1.2 million are included in cost of materials and other in our consolidated statements of income.

Other Inventory Impact

"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 our Tyler and El Dorado refineries, we compare our per barrel refining product margin to the Gulf Coast 5-3-2 crack spread consisting of (Argus pricing) WTI Cushing crude, U.S. Gulf Coast CBOB gasoline and U.S. Gulf Coast Pipeline No. 2 heating oil (ultra low sulfur diesel). For our Big Spring refinery, we compare our per barrel refining margin to the Gulf Coast 3-2-1 crack spread consisting of (Argus pricing) WTI Cushing crude, U.S. Gulf Coast CBOB gasoline and Gulf Coast ultra-low sulfur diesel. Starting in Q1 2023, for our Krotz Springs refinery, we compare our per barrel refining margin to the Gulf Coast 2-1-1 crack spread consisting of (Argus pricing) LLS crude oil, (Argus pricing) U.S. Gulf Coast CBOB gasoline and 50% of (Argus pricing) U.S. Gulf Coast Pipeline No. 2 heating oil (high sulfur diesel) and 50% of (Platts pricing) U.S. Gulf Coast Pipeline No. 2 heating oil (high sulfur diesel). Historical Gulf Coast 2-1-1 crack spread measures have been revised to conform to current period presentation. The Tyler refinery's crude oil input is primarily WTI Midland and East Texas, while the El Dorado refinery's crude input is primarily a combination of WTI Midland, local Arkansas and other domestic inland crude oil. The Big Spring refinery's crude oil input is primarily comprised of WTS and WTI Midland. The Krotz Springs refinery's crude oil input is primarily comprised of LLS and WTI Midland.
