HollyFrontier Corporation (NYSE:HFC) (“HollyFrontier” or the “Company”) today reported second quarter net income attributable to HollyFrontier stockholders of $360.8 million or $1.88 per diluted share for the quarter ended June 30, 2015, compared to $176.4 million or $0.89 per diluted share for the quarter ended June 30, 2014. Included in the current quarter results was a non-cash inventory valuation adjustment that increased earnings by $82.7 million, after-tax, or $0.43 per share.

HollyFrontier also announced today that its Board of Directors declared a regular quarterly dividend of $0.33 per share. This dividend will be paid on September 25, 2015 to holders of record of common stock on September 2, 2015.

For the second quarter, net income attributable to our stockholders, excluding the lower of cost or market inventory valuation adjustment, increased by $101.7 million compared to the same period of 2014, principally reflecting improved margins and strong refining results across our system. Crude oil charges averaged 446,000 barrels per day ("BPD"), the highest level achieved since the HollyFrontier merger in July 2011. Production levels averaged approximately 460,000 BPD. On a per barrel basis, consolidated refinery gross margin was $17.42 per produced barrel, a 20% increase compared to $14.54 for the second quarter of 2014. Total operating expenses for the quarter were $246.2 million compared to $271.7 million for the second quarter of last year, and refining operating expenses averaged $5.14 per produced barrel sold compared to $5.69 per barrel for the same period of 2014.

HollyFrontier’s President & CEO, Mike Jennings, commented, “Second quarter earnings reflect excellent operational reliability across our refining system. We reported a record quarter in terms of utilization rate, averaging 446,000 BPD of crude. Strong operations, improved realized margins and lower costs drove a greater than 60% increase in earnings per share compared to the second quarter of 2014. During the quarter we significantly reduced our share count through repurchases. Together with our quarterly dividend we returned $388.0 million in cash to shareholders, 108% of reported net income. July refinery performance continues to be strong with several of our plants currently operating at record crude processing levels. We expect high refinery utilization rates together with a constructive margin environment to drive solid financial results for the remainder of the year.”

For the second quarter of 2015, net cash provided by operations totaled $323.0 million. We executed $325.0 million in share repurchases: $25.0 million in open market purchases and $300.0 million through an accelerated share repurchase program for which we received 5.5 million shares of our common stock. The remaining shares to be repurchased under the program are expected to be determined and received in the third quarter. We declared and paid a $0.33 regular dividend to shareholders in the second quarter totaling approximately $63.0 million. Additionally, we redeemed our $150 million aggregate principal amount of 6.875% senior notes at a redemption cost of $155.2 million. At June 30, 2015, our combined balance of cash and short-term investments totaled $626.2 million and our consolidated debt was $933.2 million. Our debt, exclusive of Holly Energy Partners' debt, which is nonrecourse to HollyFrontier, was $32.3 million at June 30, 2015. We had no cash borrowings or outstanding principal under our credit facility during the quarter.

The Company has scheduled a webcast conference call for today, August 5, 2015, at 8:30 AM Eastern Time to discuss second quarter financial results. This webcast may be accessed at: https://event.webcasts.com/starthere.jsp?ei=1069761. An audio archive of this webcast will be available using the above noted link through August 19, 2015.

Segment Information

Our operations are organized into two reportable segments, Refining and HEP. Our operations that are not included in the Refining and HEP segments are included in Corporate and Other. Intersegment transactions are eliminated in our consolidated financial statements and are included in Consolidations and Eliminations. The Refining segment includes the operations of our El Dorado, Tulsa, Navajo, Cheyenne and Woods Cross refineries and NK Asphalt (aggregated as a reportable segment). Refining activities involve the purchase and refining of crude oil and wholesale and branded marketing of refined products, such as gasoline, diesel fuel and jet fuel. These petroleum products are primarily marketed in the Mid-Continent, Southwest and Rocky Mountain regions of the United States. Additionally, the Refining segment includes specialty lubricant products produced at our Tulsa refineries that are marketed throughout North America and are distributed in Central and South America. NK Asphalt operates various asphalt terminals in Arizona, New Mexico and Oklahoma.

The HEP segment involves all of the operations of HEP, a consolidated variable interest entity, which owns and operates logistics assets consisting of petroleum product and crude oil pipelines and terminal, tankage and loading rack facilities in the Mid-Continent, Southwest and Rocky Mountain regions of the United States. The HEP segment also includes a 75% interest in the UNEV Pipeline (a consolidated subsidiary of HEP) and a 25% interest in the SLC Pipeline. Revenues from the HEP segment are earned through transactions with unaffiliated parties for pipeline transportation, rental and terminalling operations as well as revenues relating to pipeline transportation services provided for our refining operations. Due to certain basis differences, our reported amounts for the HEP segment may not agree to amounts reported in HEP's periodic public filings.

Reconciliations to Amounts Reported Under Generally Accepted Accounting Principles

Reconciliations of earnings before interest, taxes, depreciation and amortization (“EBITDA”) to amounts reported under generally accepted accounting principles in financial statements.

Earnings before interest, taxes, depreciation and amortization, which we refer to as EBITDA, is calculated as net income attributable to HollyFrontier stockholders plus (i) interest expense, net of interest income, (ii) income tax provision, and (iii) depreciation and amortization. EBITDA is not a calculation provided for under accounting principles generally accepted in the United States; however, the amounts included in the EBITDA calculation are derived from amounts included in our consolidated financial statements. EBITDA should not be considered as an alternative 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 is not necessarily comparable to similarly titled measures of other companies. EBITDA is presented here because it is a widely used financial indicator used by investors and analysts to measure performance. EBITDA is also used by our management for internal analysis and as a basis for financial covenants.

Set forth below is our calculation of EBITDA.

Reconciliations of refinery operating information (non-GAAP performance measures) to amounts reported under generally accepted accounting principles in financial statements.

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 barrel is the difference between average net sales price and average cost of products per barrel of produced refined products. Net operating margin per barrel is the difference between refinery gross margin and refinery operating expenses per barrel of produced refined products. 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.

Refinery Gross and Net Operating Margins

Below are reconciliations to our consolidated statements of income for (i) net sales, cost of products (exclusive of lower of cost or market inventory valuation adjustment) and operating expenses, in each case averaged per produced barrel sold, and (ii) net operating margin and refinery gross margin. Due to rounding of reported numbers, some amounts may not calculate exactly.

(1)

We purchase finished products to facilitate delivery to certain locations or to meet delivery commitments.

(2)

We purchase crude oil that at times exceeds the supply needs of our refineries. Quantities in excess of our needs are sold at market prices to purchasers of crude oil that are recorded on a gross basis with the sales price recorded as revenues and the corresponding acquisition cost as inventory and then upon sale as cost of products sold. Additionally, at times we enter into buy/sell exchanges of crude oil with certain parties to facilitate the delivery of quantities to certain locations that are netted at cost.

(3)

Other refining segment revenue includes the incremental revenues associated with NK Asphalt, product purchased and sold forward for profit as market conditions and available storage capacity allows and miscellaneous revenue.

(4)

Other refining segment cost of products sold includes the incremental cost of products for NK Asphalt, the incremental cost associated with storing product purchased and sold forward as market conditions and available storage capacity allows and miscellaneous costs.

(5)
