Dallas, Texas, August 3, 2023 ‑ HF Sinclair Corporation (NYSE: DINO) (“HF Sinclair” or the “Company”) today reported second quarter net income attributable to HF Sinclair stockholders of $507.7 million, or $2.62 per diluted share, for the quarter ended June 30, 2023, compared to $1,221.3 million, or $5.43 per diluted share, for the quarter ended June 30, 2022. Excluding the adjustments shown in the accompanying earnings release table, adjusted net income attributable to HF Sinclair stockholders for the second quarter of 2023 was $503.8 million, or $2.60 per diluted share, compared to $1,258.5 million, or $5.59 per diluted share, for the second quarter of 2022, which excludes certain items that collectively decreased net income by $37.3 million.

HF Sinclair’s CEO, Tim Go, commented, “HF Sinclair’s strong second quarter results were driven by healthy product margins in our refining segment, coupled with solid performances from our lubricants, marketing and midstream businesses. With the majority of the planned turnaround work behind us, we believe our diversified portfolio is well positioned to capture the margins available to us for the remainder of the year. We remain focused on the reliability and integration of our asset base to further strengthen the earnings profile and free cash flow generation of HF Sinclair.”

Refining segment income before interest and income taxes was $589.8 million for the second quarter of 2023 compared to $1,558.1 million for the second quarter of 2022. The segment reported EBITDA of $702.6 million for the second quarter of 2023 compared to $1,660.9 million for the second quarter of 2022. Excluding the lower of cost or market inventory valuation charge of $26.8 million, Adjusted EBITDA in the second quarter of 2023 was $729.5 million. This decrease was principally driven by lower refining margins in both the West and Mid-Continent regions and lower refined product sales volumes, which resulted in lower refining segment earnings in the quarter. Consolidated refinery gross margin was $22.22 per produced barrel, a 39% decrease compared to $36.36 for the second quarter of 2022. Crude oil charge averaged 553,940 barrels per day (“BPD”) for the second quarter of 2023 compared to 627,310 BPD for the second quarter of 2022. This decrease was primarily a result of turnarounds at our Navajo, Parco and El Dorado refineries in the second quarter of 2023.

Renewables segment income before interest and income taxes was $4.4 million for the second quarter of 2023 compared to a loss of $(73.2) million for the second quarter of 2022. The segment reported EBITDA of $23.4 million for the second quarter of 2023 compared to $(62.8) million for the second quarter of 2022. Excluding the lower of cost or market inventory valuation adjustment, the segment reported Adjusted EBITDA of $(11.3) million for the second quarter of 2023 compared to $(28.3) million for the second quarter of 2022. Total sales volumes were 50 million gallons for the second quarter of 2023 as compared to 26 million gallons for the second quarter of 2022.

Marketing segment income before interest and income taxes was $18.6 million for the second quarter of 2023 compared to $19.5 million for the second quarter of 2022. The segment reported EBITDA of $24.6 million for the second quarter of 2023 compared to $23.9 million for the second quarter of 2022.

Lubricants and Specialty Products segment income before interest and income taxes was $51.2 million for the second quarter of 2023 compared to $135.1 million in the second quarter of 2022. The segment reported EBITDA of $71.7 million for the second quarter of 2023 compared to $155.7 million in the second quarter of 2022. This decrease was largely driven by a lower FIFO benefit from consumption of lower priced feedstock inventory for the second quarter of 2023 of $0.5 million as compared to $71.0 million for the second quarter of 2022.

Holly Energy Partners, L.P. (“HEP”) reported EBITDA of $82.2 million for the second quarter of 2023 compared to $79.8 million for the second quarter of 2022 and Adjusted EBITDA of $102.2 million for the second quarter of 2023 compared to $104.2 million for the second quarter of 2022.

Earnings before interest, taxes, depreciation and amortization, referred to as EBITDA, is calculated as net income attributable to HF Sinclair stockholders plus (i) interest expense, net of interest income, (ii) income tax provision and (iii) depreciation and amortization. Adjusted EBITDA is calculated as EBITDA plus or minus (i) lower of cost or market inventory valuation adjustments, (ii) decommissioning costs, (iii) HF Sinclair's pro-rata share of HEP's share of Osage environmental remediation costs and (iv) acquisition integration and regulatory costs.

EBITDA and Adjusted EBITDA are not calculations provided for under accounting principles generally accepted in the United States; however, the amounts included in these calculations are derived from amounts included in our consolidated financial statements. EBITDA and Adjusted EBITDA should not be considered as alternatives to net income or operating income as an indication of our operating performance or as an alternative to operating cash flow as a measure of liquidity. EBITDA and Adjusted EBITDA are not necessarily comparable to similarly titled measures of other companies. These are presented here because they are widely used financial indicators used by investors and analysts to measure performance. EBITDA and Adjusted EBITDA are also used by our management for internal analysis and as a basis for financial covenants.

Set forth below is our calculation of EBITDA and Adjusted EBITDA.

EBITDA attributable to our Refining segment is presented below:

(1)Income before interest and income taxes of our Refining segment represents income plus (i) interest expense, net of interest income and (ii) income tax provision.

EBITDA and Adjusted EBITDA attributable to our Renewables segment is set forth below:

(1)Income (loss) before interest and income taxes of our Renewables segment represents income (loss) plus (i) interest expense, net of interest income and (ii) income tax provision.

EBITDA attributable to our Marketing segment is set forth below:

(1)Income before interest and income taxes of our Marketing segment represents income plus (i) interest expense, net of interest income and (ii) income tax provision.

EBITDA attributable to our Lubricants and Specialty Products segment is set forth below.

Refinery gross margin and net operating margin are non-GAAP performance measures that are used by our management and others to compare our refining performance to that of other companies in our industry. We believe these margin measures are helpful to investors in evaluating our refining performance on a relative and absolute basis. Refinery gross margin per produced barrel sold is total Refining segment revenues less total Refining segment cost of products sold, exclusive of lower of cost or market inventory valuation adjustments, divided by sales volumes of produced refined products sold. Net operating margin per barrel sold is the difference between refinery gross margin and refinery operating expenses per produced barrel sold. These two margins do not include the non-cash effects of lower of cost or market inventory valuation adjustments or depreciation and amortization. Each of these component performance measures can be reconciled directly to our consolidated statements of income. Other companies in our industry may not calculate these performance measures in the same manner.

Renewables gross margin and net operating margin are non-GAAP performance measures that are used by our management and others to compare our renewables performance to that of other companies in our industry. We believe these margin measures are helpful to investors in evaluating our renewables performance on a relative and absolute basis. Renewables gross margin per produced gallon sold is total Renewables segment revenues less total Renewables segment cost of products sold, exclusive of lower of cost or market inventory valuation adjustments, divided by sales volumes of produced renewables products sold. Net operating margin per produced gallon sold is the difference between renewables gross margin and renewables operating expenses per produced gallon sold. These two margins do not include the non-cash effects of lower of cost or market inventory valuation adjustments and depreciation and amortization. Each of these component performance measures can be reconciled directly to our consolidated statements of income. Other companies in our industry may not calculate these performance measures in the same manner.

Marketing gross margin is a non-GAAP performance measure that is used by our management and others to compare our marketing performance to that of other companies in our industry. We believe this margin measure is helpful to investors in evaluating our marketing performance on a relative and absolute basis. Marketing gross margin per gallon sold is total Marketing segment revenues less total Marketing segment cost of products sold divided by sales volumes of marketing products sold. This margin does not include the non-cash effects of depreciation and amortization. This component performance measure can be reconciled directly to our consolidated statements of income. Other companies in our industry may not calculate these performance measures in the same manner.

Reconciliation of net income attributable to HF Sinclair stockholders to adjusted net income attributable to HF Sinclair stockholders

Adjusted net income attributable to HF Sinclair stockholders is a non-GAAP financial measure that excludes non-cash lower of cost or market inventory valuation adjustments, decommissioning costs, HEP's share of Osage environmental remediation costs and acquisition integration and regulatory costs. We believe this measure is helpful to investors and others in evaluating our financial performance and to compare our results to that of other companies in our industry. Similarly titled performance measures of other companies may not be calculated in the same manner.

(1)Represents adjustment to GAAP income tax expense to arrive at adjusted income tax expense, which is computed as follows:

(2)Non-GAAP income tax expense is computed by (a) adjusting HF Sinclair’s consolidated estimated Annual Effective Tax Rate (“AETR”) for GAAP purposes for the effects of the above Non-GAAP adjustments, (b) applying the resulting Adjusted Non-GAAP AETR to Non-GAAP adjusted income before income taxes and (c) adjusting for discrete tax items applicable to the period.

(3)Adjusted earnings per share - diluted is calculated as adjusted net income attributable to HF Sinclair stockholders divided by the average number of shares of common stock outstanding assuming dilution, which is based on weighted-average diluted shares outstanding as that used in the GAAP diluted earnings per share calculation. Income allocated to participating securities, if applicable, in the adjusted earnings per share calculation is calculated the same way as that used in GAAP diluted earnings per share calculation.
