BRENTWOOD, Tenn., Feb. 19, 2019 (GLOBE NEWSWIRE) -- Delek US Holdings, Inc. DK ("Delek US") today announced financial results for its fourth quarter ended December 31, 2018. Delek US reported fourth quarter 2018 net income of $121.6 million, or $1.48 per diluted share, versus net income of $211.1 million, or $2.56 per diluted share, for the quarter ended December 31, 2017.  On an adjusted basis, Delek US reported adjusted net income of $129.8 million, or $1.59 per diluted share for the fourth quarter 2018. This compares to adjusted net income of $47.6 million, or $0.58 per diluted share, in the prior-year period. Adjusted earnings before interest, taxes, depreciation and amortization ("Adjusted EBITDA") was $251.4 million compared to Adjusted EBITDA of $165.1 million in the prior-year period. Reconciliations of net income reported under U.S. GAAP to adjusted net income and Adjusted EBITDA are included in the financial tables attached to this release.

Quarterly results improved year-over-year primarily due to better performance in the refining segment. The refining segment contribution margin increased to $235.3 million in the fourth quarter 2018, compared to a contribution margin of $185.8 million in the prior-year period. The improved results in refining benefited from favorable crude oil differentials and lower RINs expense, which more than offset a lower crack spread environment. The logistics segment contribution margin improved to $45.0 million during the quarter compared to $32.7 million in the prior-year period, as it primarily benefited from the drop down of the Big Spring refinery logistics assets that was effective March 1, 2018.  The retail segment contribution margin was $13.1 million during the quarter compared to $13.3 million in the prior year period.

For the full year 2018, Delek US reported net income of $345.6 million, or $4.02 per diluted share, compared to net income of $288.8 million, or $4.00 per diluted share in 2017. On an adjusted basis, net income was $406.3 million, or $4.80 per diluted share in 2018, compared to net income of $95.4 million, or $1.33 per diluted share in 2017. This increase in the adjusted results on a year-over-year basis was primarily due to a full year of contribution from the Alon USA operations acquired effective July 1, 2017, and a larger Midland WTI to Cushing crude oil price discount during 2018.  Adjusted EBITDA was $854.4 million compared to Adjusted EBITDA of $417.8 million in the prior year period.

Uzi Yemin, Chairman, President and Chief Executive Officer of Delek US, stated, "2018 was a great year for Delek US. We achieved record EBITDA and strong cash flow allowing us to invest $322 million in our business, while returning $445 million to shareholders, or approximately 16 percent of our current market capitalization, through dividends and share repurchases. In addition, we successfully integrated the Alon acquisition, captured approximately $135 million of synergies, improved the Krotz Springs refinery and simplified our corporate structure. We ended the year with approximately $1.1 billion of cash, and we are well positioned with the financial flexibility to execute our midstream growth initiatives that are expected to support a projected $370 to $390 million of EBITDA from our midstream operations by 2022. We are constructing our Big Spring Gathering system in the Permian Basin and will manage our capital spending based on our producers' acreage development plans during the year. We continue to develop our long-haul crude oil pipeline strategy, and believe that a potential combination with another pipeline could create a more capital efficient and better utilized project for all partners. In addition to investing in our business, our capital allocation program includes returning excess cash flow to investors. To that end, we increased our dividend and expect to repurchase $50 million of Delek US stock during the first quarter 2019. We remain focused on operating reliable and efficient operations, returning cash to our shareholders, investing in our business and exploring opportunities to provide future growth to create long term value for our shareholders."

Regular Quarterly Dividend and Share Repurchase
Delek US announced today its Board of Directors declared a regular quarterly cash dividend of $0.27 per share. This represents a 3.8 percent increase from our previous regular quarterly dividend. Shareholders of record on March 5, 2019 will receive this cash dividend payable on March 19, 2019.

During the fourth quarter 2018, Delek US repurchased approximately 4.2 million shares of Delek US common stock for approximately $157.9 million, with an average price of $37.81 per share.  For the year ended December 31, 2018, Delek US repurchased approximately 9.0 million shares for approximately $365.3 million, with an average price of $40.49 per share.  At December 31, 2018, there was approximately $409.7 million of total available authorization remaining to repurchase shares.  Delek US expects to repurchase approximately $50 million of Delek US common stock during the first quarter 2019.

Liquidity
As of December 31, 2018, Delek US had a cash balance of $1,079.3 million and total consolidated debt of $1,783.3 million, resulting in net debt of $704.0 million.  As of December 31, 2018, Delek US' subsidiary, Delek Logistics, had $700.4 million of total debt and $4.5 million of cash, which is included in the consolidated amounts on Delek US' balance sheet. Excluding Delek Logistics, Delek US had approximately $1,074.8 million in cash and $1,082.9 million of debt, or an $8.1 million net debt position.

Refining Segment
Refining segment contribution margin was $235.3 million in the fourth quarter 2018 compared to $185.8 million in the fourth quarter 2017. On a year-over-year basis, results benefited from a wider discount for the Midland to Cushing differential, and lower RINs expense, which more than offset a lower crack spread environment. In the fourth quarter 2018, results included an approximate $16.0 million reduction in operating expenses related to environmental indemnification proceeds at the idled Bakersfield, California location. The Gulf Coast 5-3-2 crack spread decreased to $12.50 per barrel for the fourth quarter 2018, compared to $14.66 per barrel for the same period in 2017.

Results during the fourth quarter 2018 do not fully reflect the Midland to Cushing market differential during the period due to an inventory timing effect. The estimated realized Midland to Cushing differential included in reported results was approximately $10.68 per barrel during the fourth quarter 2018, taking into consideration an inventory timing effect.

During the fourth quarter 2018, the Midland WTI crude oil differential to Brent crude oil was an average discount of $15.05 per barrel compared to $5.95 per barrel in the prior-year period. The Midland WTI crude oil differential to Cushing WTI was an average discount of $8.59 per barrel in fourth quarter 2018 compared to an average discount of $0.28 per barrel in the fourth quarter 2017.  Backwardation in the oil futures market was $0.12 per barrel in the fourth quarter 2018, compared to contango of $0.39 per barrel in the fourth quarter 2017.

Logistics Segment
The logistics segment contribution margin in the fourth quarter 2018 increased to $45.0 million compared to $32.7 million in the fourth quarter 2017. The primary factor that increased contribution margin was a benefit from the drop down of the Big Spring refinery logistics assets that was effective March 1, 2018, which was partially offset by a lower gross margin in west Texas wholesale marketing.

Retail Segment
For the fourth quarter 2018, contribution margin was $13.1 million compared to $13.3 million in the prior year period for the retail segment. Merchandise sales were approximately $81.0 million with an average retail margin of 30.2% in the fourth quarter 2018, compared to merchandise sales of approximately $84.2 million with an average retail margin of 31.5% in the prior year period. Approximately 53.3 million retail fuel gallons were sold at an average margin of $0.30 per gallon in the fourth quarter 2018 compared to 53.2 million retail fuel gallons sold at an average margin of $0.17 per gallon in the fourth quarter 2017. On a same store sales basis in the fourth quarter 2018, merchandise sales decreased 0.7% and fuel gallons sold increased 0.1% compared to the prior-year period.

Corporate/Other Segment
Contribution margin from the Corporate/Other segment was a loss of $8.0 million in the fourth quarter 2018 compared to a loss of $17.5 million in the prior-year period. The net hedging gain included in this segment in the fourth quarter 2018 was $11.3 million compared to a net hedging loss of $4.0 million in the prior-year period.

Investors are cautioned that the following important factors, among others, may affect these forward-looking statements. These factors include, but are not limited to: uncertainty related to timing and amount of future share repurchases and dividend payments; risks and uncertainties with respect to the quantities and costs of crude oil we are able to obtain and the price of the refined petroleum products we ultimately sell; risks related to Delek US' exposure to Permian Basin crude oil, such as supply, pricing, gathering, production and transportation capacity; gains and losses from derivative instruments; management's ability to execute its strategy of growth through acquisitions and the transactional risks associated with acquisitions and dispositions; acquired assets may suffer a diminishment in fair value as a result of which we may need to record a write-down or impairment in carrying value of the asset; changes in the scope, costs, and/or timing of capital and maintenance projects; the ability to obtain commitments and construct the pipeline; operating hazards inherent in transporting, storing and processing crude oil and intermediate and finished petroleum products; our competitive position and the effects of competition; the projected growth of the industries in which we operate; general economic and business conditions affecting the southern United States; and other risks described in Delek US' filings with the United States Securities and Exchange Commission (the "SEC"), including risks disclosed in our Annual Report on Form 10-K, Quarterly Reports on Form 10-Q and other filings and reports with the SEC.

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 GAAP financial information presented in accordance with U.S. GAAP. These financial and operational non-GAAP measures are important factors in assessing our operating results and profitability and include:

• Adjusted net income (loss) - calculated as net income attributable to Delek adjusted for certain identified infrequently occurring items, non-cash items and items that are not attributable to our on-going operations (collectively, "Adjusting Items") recorded during the period;
  
  
• Adjusted unrealized hedging (gains) losses - calculated as GAAP unrealized (gains) losses on commodity derivatives that are economic hedges but not designated as hedging instruments adjusted to exclude unrealized (gains) losses where the instrument has matured but where it has not cash settled as of the balance sheet date. This adjustment more appropriately aligns matured commodity derivatives gains and losses with the recognition of the related cost of materials and other. There are no premiums paid or received at the inception of the derivative contracts, and upon settlement there is no cost recovery associated with these contracts;
  
  
• 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 attributable to Delek adjusted to add back interest expense, income tax expense, depreciation and amortization;
  
  
• Adjusted EBITDA - calculated as EBITDA adjusted for the 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 the difference between total refining revenues and total cost of materials and other; and
  
  
• Refining margin per throughput barrel - calculated as refining margin divided by our average refining throughput in barrels per day multiplied by 1,000 and multiplied by the number of days in the period.

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 comparability between periods through the exclusion of certain items that we believe are not indicative of our core operating performance and they may obscure our underlying results and trends.

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 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.

Consolidated Balance Sheets (Unaudited)

Delek US Holdings, Inc.
Consolidated Statements of Income (Unaudited) ⁽¹⁾

⁽¹⁾  Certain changes to presentation of the prior period statements of income have been made in order to conform to the current period presentation, primarily relating to the addition of a subtotal entitled 'cost of sales' which includes all costs directly attributable to the generation of the related revenue, as defined by GAAP, and the retitling of what was previously referred to as 'cost of goods sold' to 'cost of materials and other'. Operating expenses and depreciation and amortization related to the wholesale business and the retail business are excluded from cost of sales because they primarily relate to costs associated with selling the products.

⁽²⁾   Net revenues and cost of materials and other for the year ended December 31, 2018 reflect a correction of an intercompany elimination related to the nine months ended September 30, 2018, which resulted in an increase in net revenues and cost of materials and other of $347.1 million not previously reflected on the unaudited consolidated financial statements in our September 30, 2018 Quarterly Report on Form 10-Q filed on November 9, 2018, of which $73.3 million related to the three and six months ended June 30, 2018 not previously reflected on the unaudited consolidated financial statements in our June 30, 2018 Quarterly Report on Form 10-Q filed on August 9, 2018.

⁽¹⁾  The condensed statements of cash flows for the three months ended December 31, 2018 and 2017 have been derived from taking the difference between the year-to-date statements of cash flows for the year ended December 31, 2018 and 2017 compared to the nine months ended September 30, 2018 and 2017 (as previously reported on our Quarterly Reports on Forms 10-Q), respectively. Therefore, any changes in presentation that occurred in year-to-date cash flow results for the years ended December 31, 2018 or 2017 are reflected in the three-month periods then ended, as no retrospective changes in presentation to statements previously reported on our Quarterly Reports on Forms 10-Q have been made.

⁽¹⁾ Assets held for sale of $160.0 million are included in the corporate, other and eliminations segment as of December 31, 2017.

⁽²⁾ The corporate, other and eliminations segment results of operations for the year ended December 31, 2018 includes Canada trading activity which was previously included and reported in the refining segment for the three months ended March 31, 2018.

⁽³⁾ Net revenues and cost of materials and other for the year ended December 31, 2018 reflect a correction of an intercompany elimination in the refining segment related to the nine months ended September 30, 2018, which resulted in an increase in net revenues and cost of materials and other of $347.1 million not previously reflected on the unaudited consolidated financial statements in our September 30, 2018 Quarterly Report on Form 10-Q filed on November 9, 2018, of which $73.3 million related to the three and six months ended June 30, 2018 not previously reflected on the unaudited consolidated financial statements in our June 30, 2018 Quarterly Report on Form 10-Q filed on August 9, 2018.

⁽⁴⁾ Capital spending excludes transaction costs capitalized in the amount of $0.4 million during the year ended December 31, 2018, that relate to the Big Spring logistics assets acquisition.

⁽¹⁾  Total sales volume includes 2,106 and 986 bpd sold to the logistics segment during the three months and year ended December 31, 2018, respectively, and 3,792 and 1,592 bpd during the three months and year ended December 31, 2017, respectively.  Total sales volume also includes sales of 164 and 193 bpd of intermediate and finished products to the El Dorado refinery during the three months and year ended December 31, 2018, respectively, and 154 and 129 bpd during the three months and year ended December 31, 2017, respectively.  Total sales volume also includes 284 and 399 bpd of produced finished product sold to the Big Spring refinery and 476 and 232 bpd sold to the Krotz Springs refinery during the three months and year ended December 31, 2018, respectively. Total sales volume excludes 4,015 and 4,444 bpd of wholesale activity during the three months and year ended December 31, 2018, respectively, and 3,238 and 4,209 bpd of wholesale activity during the three months and year ended December 31, 2017, respectively.

⁽²⁾  Total sales volume includes 1,035 and 1,387 bpd of produced finished product sold to the Tyler refinery during the three months and year ended December 31, 2018, respectively, and 189 and 514 bpd during the three months and year ended December 31, 2017, respectively; 39,999 and 27,048 bpd of produced finished product sold to the Krotz Springs refinery during the three months and year ended December 31, 2018, respectively; 32 and 302 bpd of produced finished product sold to the Big Spring refinery during the three months and year ended December 31, 2018, respectively; 14 and 140 bpd of produced finished product sold to logistics segment during the three months and year ended December 31, 2018, and 0 and 0 bpd during the year ended December 31, 2017, respectively; 0 and 17 bpd of produced finished product sold to the retail segment  during the three months and year ended December 31, 2018, respectively; and 617 and 406 bpd of produced finished product sold to Alon Asphalt Company during the three months and year ended December 31, 2018, respectively.  Total sales volume excludes 42,447 and 47,422 bpd of wholesale activity during the three months and year ended December 31, 2018, respectively, and 43,627 and 25,750 bpd of wholesale activity during the year ended December 31, 2017, respectively.

⁽³⁾  Total sales volume includes 728 and 554 bpd sold to the Tyler refinery, 13,647 and 13,967 bpd sold to the retail segment, 9,099 and 10,005 bpd sold to the logistics segment and 1,997 and 1,688 bpd sold to Alon Asphalt Company during the three months and year ended December 31, 2018, respectively.

⁽⁴⁾  Sales volume includes 1,200 and 19,039 bpd sold to the El Dorado refinery and 0 and 606 bpd sold to the Tyler refinery during the three months and year ended December 31, 2018, respectively.

⁽⁵⁾  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 WTI Cushing crude, U.S. Gulf Coast CBOB and U.S, Gulf Coast Pipeline No. 2 heating oil (high sulfur diesel).  For our Big Spring refinery, we compare our per barrel refined product margin to the Gulf Coast 3-2-1 crack spread consisting of WTI Cushing crude, Gulf Coast 87 Conventional gasoline and Gulf Coast ultra low sulfur diesel, and for our Krotz Springs refinery, we compare our per barrel refined product margin to the Gulf Coast 2-1-1 crack spread consisting of LLS crude oil, Gulf Coast 87 Conventional gasoline and U.S, Gulf Coast Pipeline No. 2 heating oil (high sulfur diesel).  The Tyler refinery's crude oil input is primarily WTI Midland and east Texas, while the El Dorado refinery's crude input is primarily 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.  The Big Spring and Krotz Springs refineries were acquired July 1, 2017 as part of the Delek US/Alon USA Merger, so Gulf Coast 3-2-1 and 2-1-1 crack spreads, LLS and WTS statistics are presented only for the period Delek US owned these refineries.

⁽¹⁾  Adjusted refining margin per barrel is presented to provide a measure to evaluate performance excluding inventory valuation adjustments and other items at the individual refinery level. Delek US believes that the presentation of adjusted measures provides useful information to investors in assessing its results of operations at each refinery. Because adjusted refining margin per barrel may be defined differently by other companies in its industry, Delek US' definition may not be comparable to similarly titled measures of other companies.

⁽²⁾  Tyler adjusted refining margins exclude the following items.

Net inventory valuation benefit (loss) - There was approximately $(38.8) million and $14.8 million of valuation benefit (loss) in the fourth quarter 2018 and 2017, respectively. There was approximately $(37.9) million and $14.5 million of valuation benefit (loss) in the year ended December 31, 2018 and 2017, respectively. These amounts resulted from lower of cost or market adjustments on LIFO inventory in the respective periods.

Biodiesel tax credit allocation - In the first quarter 2018, approximately $15.4 million related to the biodiesel tax credit for 2017 that is included in the renewables portion of the refining segment was allocated to Tyler.

Non-cash RINs inventory mark-to-market - Relates to a mark-to-market of the Renewable Identification Numbers ("RINs") inventory position in the amount of $21.0 million in the second quarter 2018. The inventory position was higher due to the waiver received by the El Dorado refinery in March 2018.

⁽⁴⁾  Big Spring adjusted refining margins exclude the following items.

Net inventory valuation benefit (loss) - There were approximately $(3.5) million and $(0.4) million of valuation benefit (loss) in the fourth quarter 2018 and 2017, respectively. There was approximately $(3.5) million and $(0.4) million of valuation benefit (loss) in the year ended December 31, 2018 and 2017, respectively. These amounts resulted from lower of cost or market adjustments on FIFO inventory in the respective period.

RIN waiver - In March 2018, the Krotz Springs, Louisiana refinery received approval from the Environmental Protection Agency for a small refinery exemption from the requirements of the renewable fuel standard for the 2017 calendar year. This waiver equated to a benefit of approximately $31.6 million recognized in the first quarter 2018.

Non-cash RINs inventory mark-to-market - Relates to a mark-to-market of the Renewable Identification Numbers ("RINs") inventory position in the amount of $5.9 million in the second quarter 2018. The inventory position was higher due to the waiver received by the Krotz Springs refinery in March 2018.
