Holly Corporation Reports First Quarter Results

DALLAS, May 5 /PRNewswire-FirstCall/ -- Holly Corporation today reported quarterly net income of $13.1 million ($0.41 per basic and diluted share) for the three months ended March 31, 2005, compared to net income of $14.0 million ($0.45 per basic and $0.43 per diluted share) for the three months ended March 31, 2004.

Earnings for the first quarter of 2005 as compared to the first quarter of 2004 were down by $0.9 million as an increase in refinery production was offset by higher related operating expenses and by the attribution in the first quarter of 2005 of approximately half of the income from our refined product pipelines and terminals to owners (other than the Company) of interests in Holly Energy Partners, L.P. ("HEP"). HEP has since July 2004 owned and operated product pipelines and terminals previously 100% owned by the Company. Overall refinery production levels increased 7% with first quarter total production at 116,000 barrels per day ("bpd"), due to increased production at all facilities. Company-wide refinery margins were $7.55 per barrel for the first quarter of 2005 compared to reported margins of $8.47 per barrel for the first quarter of 2004; however, refinery margins for the first quarter of 2005 were reduced by pipeline and terminalling fees to HEP for transportation services that were not charged against margins in the first quarter of 2004. Excluding pipeline and terminalling fees to HEP for the 2005 quarter, company-wide refinery margins were $8.47 for the first quarters of both 2005 and 2004.

Sales and other revenues increased 41% for the first quarter of 2005 as compared to the first quarter of 2004, due principally to higher refined product sales prices, and to a lesser degree, increased volumes sold from our Navajo and Woods Cross refineries. Overall refined product sales volumes increased 12% for the first quarter as compared to the prior year's first quarter. Cost of products sold was also higher for the first quarter of 2005 year due to higher costs of purchased crude oil and the higher volumes. Operating expenses increased due to higher production levels, increased utility costs, and the inclusion of the NK Asphalt Partners joint venture (now doing business as Holly Asphalt Company) in the 2005 consolidated statements, following our February 2005 purchase of the other partner's interest. Selling, general and administrative expenses decreased from the first quarter of 2004 to the first quarter of 2005 due primarily to $3.7 million of legal costs we incurred in the 2004 first quarter associated with the litigation with Frontier Oil Corporation, partially offset by additional employee compensation expense in 2005 from the addition of personnel in 2004 and increased equity-based incentive compensation. Additionally, after the transfer of the Company's product pipeline and terminal assets to HEP in July 2004, earnings were reduced by the share of pipeline and terminalling fees charged to the Company by HEP that is attributable to holders of units other than the Company (which owned approximately 51% until the end of February 2005 and currently owns approximately 48% of HEP).

"We are pleased with our 2005 first quarter operations, as we generated $33.4 million of earnings before interest, taxes and depreciation ("EBITDA") in the quarter," said Mathew Clifton, President of Holly. "While refinery margins started 2005 at seasonally reduced levels, especially at the Woods Cross Refinery, they rebounded nicely at all refineries through the quarter and are currently at very high levels. Additionally in the 2005 first quarter, we took major steps in the execution of our previously announced value-added refinery initiatives for 2005 to improve profitability, including strides to improve higher valued product yields and raise refinery utilization rates at our facilities. With the large sour crude discounts continuing to be experienced in the market place, we are benefiting from our 80% sour crude oil capabilities and will move forward in our efforts to further increase our capacity to process sour crude oil. We will continue to explore operational improvement initiatives and prudently deploy capital to improve the profitability of our existing operations. With respect to Holly Energy Partners, we are pleased with their operations, and their successful integration of pipelines and terminals acquired from Alon USA, Inc. at the end of February. On the refining side, we believe industry fundamentals are in our favor for the foreseeable future as growth in demand for refined products should continue to exceed refining supply. As we look ahead, we will strive to operate our assets safely, reliably and in an environmentally responsible manner, while continuing to look for opportunities for strategic acquisition and organic growth opportunities, where we can leverage our strong financial condition."

Our two major business segments are: Refining and HEP. The Refining segment presented in the March 31, 2004 quarterly report on Form 10-Q is not the same Refining segment as presented below. The Refining segment for the three months ended March 31, 2004 has been restated to include results of operations involving assets included in HEP prior to the contribution on July 13, 2004. The HEP segment will not have any activity for the three months ended March 31, 2004 as HEP was not formed until July 13, 2004.

Three Months Ended March 31, 2005 2004 (In thousands) Sales and other revenue (A) Refining $644,277 $462,681 HEP 16,513 --- Corporate and Other 365 490 Consolidations and Eliminations (9,430) (114) Consolidated $651,725 $463,057 Income (loss) from operations (A) Refining $30,377 $36,753 HEP 7,785 --- Corporate and Other (12,253) (11,687) Consolidated $25,909 $25,066 (A) The Refining segment includes our principal refinery in Artesia, New Mexico, which is operated in conjunction with refining facilities in Lovington, New Mexico (collectively, the "Navajo Refinery"), the Woods Cross Refinery near Salt Lake City, Utah, and our refinery in Great Falls, Montana. The petroleum products marketed by the Refining segment are marketed in Texas, New Mexico, Arizona, Utah, Wyoming, Montana, Idaho, Washington and northern Mexico. Included in the Refining segment are costs relating to certain crude oil and intermediate product pipelines that we still own and operate in conjunction with our refining operations as part of the supply networks of the refineries. The Refining segment also includes the purchasing of crude oil and wholesale and branded marketing of refined products. The Refining segment also includes the equity in earnings from our 49% interest in NK Asphalt Partners prior to February 2005. In February 2005, we acquired the other 51% interest in the joint venture from our other partner; subsequent to the purchase, we are including the operations of NK Asphalt Partners in our consolidated financial statements. NK Asphalt Partners, dba Holly Asphalt Company, manufactures and markets asphalt and asphalt products in Arizona, New Mexico, Texas and California. The cost of pipeline transportation and terminal services provided by HEP is included in the Refining segment. The HEP segment involves all of the operations of HEP, including approximately 1,300 miles (780 miles prior to the Alon asset acquisition) of its pipeline assets principally in Texas, New Mexico and Oklahoma and refined product terminals in several Southwest and Rocky Mountain states. The HEP segment also includes its 70% interest in the Rio Grande Pipeline Company which provides petroleum products transportation. Revenues from the HEP segment were 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 and from its interest in the Rio Grande Pipeline Company. Results of operations involving the assets included in the HEP segment prior to July 13, 2004 are included in the Refining segment for reporting purposes. Our operations not included in the other two reportable segments are included in Corporate and Other, which includes costs of Holly Corporation, the parent company, consisting primarily of general and administrative expenses and interest changes as well as a small-scale oil and gas exploration and production program, and a small equity investment in retail gasoline stations and convenience stores. The elimination column includes the elimination of the revenue and costs associated with our pipeline transportation services between us and HEP as well as the elimination of our equity in earnings of HEP.

(H) For comparability purposes, if amounts paid to HEP for transportation were excluded, as was the case prior to HEP's initial public offering, the refinery gross margins for the three months ended March 31, 2005 prior to the inclusion of those transportation costs were $10.02 for Navajo Refinery, $3.37 for Woods Cross Refinery, and $8.47 for the consolidated operations.

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 plus (i) interest expense net of interest income, (ii) income tax provision, and (iii) depreciation, depletion and amortization. EBITDA is not a calculation based upon 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. Three Months Ended March 31, 2005 2004 (In thousands) Net income $13,066 $13,962 Add provision for income tax 8,180 8,882 Add interest expense 1,544 955 Subtract interest income (1,168) (77) Add depreciation and amortization 11,819 9,924 EBITDA $33,441 $33,646

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.

We calculate refinery gross margin and net operating margin using net sales, cost of products and operating expenses, in each case averaged per produced barrel sold. These two margins do not include the effect of depreciation, depletion and amortization. Each of these component performance measures can be reconciled directly to our Statement of Income.

Other companies in our industry may not calculate these performance measures in the same manner.

Refinery Gross Margin

Refinery gross margin per barrel is the difference between average net sales price and average cost of products per barrel of produced refined products. Refinery gross margin for each of our refineries and for all of our refineries on a consolidated basis is calculated as shown below.

Three Months Ended March 31, 2005 2004 Average per produced barrel: Navajo Refinery Net sales $57.50 $44.98 Less cost of products 48.68 35.10 Refinery gross margin $8.82 $9.88 Woods Cross Refinery Net sales $54.23 $43.84 Less cost of products 51.06 40.13 Refinery gross margin $3.17 $3.71 Montana Refinery Net sales $54.08 $40.41 Less cost of products 45.60 32.95 Refinery gross margin $8.48 $7.46 Consolidated Net sales $56.61 $44.52 Less cost of products 49.06 36.05 Refinery gross margin $7.55 $8.47 Net Operating Margin

Net operating margin per barrel is the difference between refinery gross margin and refinery operating expenses per barrel of produced refined products. Net operating margin for each of our refineries and for all of our refineries on a consolidated basis is calculated as shown below.

Three Months Ended March 31, 2005 2004 Average per produced barrel: Navajo Refinery Refinery gross margin $8.82 $9.88 Less refinery operating expenses 3.09 3.07 Net operating margin $5.73 $6.81 Three Months Ended March 31, 2005 2004 Average per produced barrel: Woods Cross Refinery Refinery gross margin $3.17 $3.71 Less refinery operating expenses 4.33 4.13 Net operating margin $(1.16) $(0.42) Montana Refinery Refinery gross margin $8.48 $7.46 Less refinery operating expenses 9.31 8.12 Net operating margin $(0.83) $(0.66) Consolidated Refinery gross margin $7.55 $8.47 Less refinery operating expenses 3.66 3.53 Net operating margin $3.89 $4.94

Below are reconciliations to our Statement of Income for (i) net sales, cost of products 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.
