Exhibit 99.1

For Immediate Release

HOLLY CORPORATION REPORTS RECORD SECOND QUARTER RESULTS

     Dallas, Texas, August 2, 2006 — Holly Corporation (NYSE-HOC) (“Holly” or the “Company”) today reported record quarterly net income of $93.1 million ($1.62 per basic and $1.60 per diluted share) for the three months ended June 30, 2006, compared to net income of $52.4 million ($0.83 per basic and $0.81 per diluted share) for the three months ended June 30, 2005. Net income was $139.9 million ($2.42 per basic and $2.37 per diluted share) for the six months ended June 30, 2006, compared to net income of $66.1 million ($1.05 per basic and $1.02 per diluted share) for the six months ended June 30, 2005.

     As previously reported, on March 31, 2006 we sold our petroleum refinery in Great Falls, Montana (the “Montana Refinery”) to a subsidiary of Connacher Oil and Gas Limited. Accordingly, the results of operations of the Montana Refinery and a gain on the sale of $14.0 million, net of income taxes of $8.3 million, are shown in discontinued operations. Income from continuing operations for the three months ended June 30, 2006 was $87.7 million ($1.53 per basic and $1.51 per diluted share) as compared to $51.1 million ($0.81 per basic and $0.79 per diluted share) for the three months ended June 30, 2005. Income from continuing operations for the six months ended June 30, 2006 was $118.9 million ($2.06 per basic and $2.01 per diluted share) as compared to $65.5 million ($1.04 per basic and $1.01 per diluted share) for the six months ended June 30, 2005.

     Income from continuing operations increased $36.6 million for the second quarter of 2006 and $53.4 million for the first six months of 2006 as compared to the second quarter and first six months of 2005, respectively, due principally to improved refined product margins experienced in the current year. In addition, earnings benefited in 2006 from the start-up in December 2005

of our ROSE unit (the ROSE unit converts a significant portion of lower value asphalt into high value transportation fuels) that contributed to higher refinery yields in the current year, and revenues in the 2006 second quarter attributable to sales of $12.0 million of sulfur credits generated because our Navajo Refinery is making gasoline that is substantially lower in sulfur than required by EPA regulations. These favorable factors were partially offset by the effects of reduced production volumes and higher operating costs and expenses. Overall refinery production levels from continuing operations showed a decrease of 12% in the 2006 second quarter and 7% for the six months ended June 30, 2006, as compared to the same periods in 2005 due primarily to production downtime arising from planned capital and refinery maintenance projects at our Navajo and Woods Cross Refineries. Refinery gross margins from continuing operations were $22.37 per produced barrel for the second quarter of 2006 compared to margins of $14.02 per produced barrel for the second quarter of 2005, and $16.95 per produced barrel for the six months ended June 30, 2006 compared to margins of $10.74 per produced barrel for the six months ended June 30, 2005.

     Sales and other revenues from continuing operations increased 54% for the second quarter of 2006 and 41% for the first six months of 2006 as compared to the second quarter and first six months of 2005, respectively, due principally to increased refined product prices. Cost of products sold was higher in the second quarter and first six months of 2006 due principally to the higher costs of purchased crude oil. Operating expenses increased due principally to higher utility costs (natural gas and electricity) and refinery maintenance, partially offset by the exclusion of operating costs of Holly Energy Partners, L.P. (“HEP”) in the first six months of 2006 resulting from the deconsolidation of HEP effective July 1, 2005. General and administrative expenses increased due primarily to increased equity-based incentive compensation. The Company’s effective tax rate decreased in 2006 as compared to 2005 primarily due to the impact of the American Jobs Creation Act of 2004 that provides tax incentives for small business refiners incurring costs to produce ultra low sulfur diesel fuel.

     “We are especially pleased with our 2006 second quarter results, as we realized solid refined product margins and completed significant capital projects,” said Matthew Clifton, Chief Executive Officer of Holly. “Our income from continuing operations was at a record quarterly level, and we generated $146.4 million of earnings before interest, taxes and depreciation

- 2 -

(“EBITDA”) for the quarter. I am very pleased that both our Navajo and Woods Cross refineries completed major capital projects in the second quarter allowing the refineries to meet the industry-wide requirements for ultra low sulfur diesel specifications and providing a 9% expansion of the crude capacity at the Navajo Refinery. Our employees and support teams are to be commended for their fine contributions on these projects that allowed us to meet the required clean diesel fuel standards by the June 2006 deadline.”

     “During the 2006 second quarter, our shareholders benefited from a two-for-one stock split and we continued with our $200 million share repurchase program, purchasing 676,300 shares during the quarter at an average cost of $40.03. In addition to the stock repurchase program, in this era of high profitability, we are reinvesting significant sums in capital projects at our refineries aimed at maximizing shareholder return. Together with our just completed clean diesel fuel projects at both of our refineries, we completed the first phase of an expansion at the Navajo Refinery to 82,000 barrels-per-day, and with the ROSE unit completed in late 2005, we expect a very favorable overall return on these investments. Additionally, as previously reported, our Board of Directors is evaluating proposed projects to significantly enhance our feedstock flexibility at the Navajo and Woods Cross refineries and to expand the capacity of both refineries.”

     “Looking forward, we remain convinced that the strong industry fundamentals will remain in our favor, as demand for refined products should continue to press the country’s refining supply capabilities. This, combined with our sour crude oil processing capabilities and our continued execution of value-added refining projects, should favorably impact our future earnings levels. With respect to Holly Energy Partners, we continue to be extremely pleased with its operations to date and look forward to its continued success,” said Clifton.

     On May 11, 2006, we announced that our Board of Directors approved a two-for-one stock split payable in the form of a stock dividend of one share of common stock for each issued and outstanding share of common stock. The dividend was paid on June 1, 2006 to all holders of record of common stock at the close of business on May 22, 2006. All references to the number of shares of common stock and per share amounts have been adjusted to reflect the split on a retrospective basis.

     Due to the sale of the Montana Refinery, we have reclassified certain amounts previously reported and now report as discontinued operations. Also, as previously reported, we adopted Statement of Financial Accounting Standards (“SFAS”) 123 (revised) on July 1, 2005 based on modified retrospective application with early application under SFAS 123 (revised) to earlier quarters in 2005, resulting in a previously reported restatement to the financial statements for the three months ended June 30, 2005.

Our sole reportable business segment is Refining after the deconsolidation of HEP effective July 1, 2005. From the closing of the initial public offering of HEP on July 13, 2004 through June 30, 2005, our segments reflected two business divisions, Refining and HEP. The HEP segment did not have any activity subsequent to the deconsolidation effective July 1, 2005.

(1) The Refining segment involves the purchase and refining of crude oil and wholesale and branded marketing of refined products, such as gasoline, diesel fuel and jet fuel, and includes our Navajo Refinery and Woods Cross Refinery. Although we previously included the Montana Refinery in the Refining segment, the results from the Montana Refinery are now reported in discontinued operations and are not included in the above tables. The petroleum products produced by the Refining segment are marketed in Texas, New Mexico, Arizona, Utah, Wyoming, Idaho, Washington and northern Mexico. The Refining segment also includes certain crude oil pipelines that we own and operate in conjunction with our refining operations as part of the supply networks of the refineries. 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 include the operations of NK Asphalt Partners in our consolidated financial statements. NK Asphalt Partners, doing business as 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 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 a 70% interest in Rio Grande which provides petroleum products transportation. 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 and from its interest in Rio Grande. Our operations not included in the reportable segment or 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 charges as well as a small-scale oil and gas exploration and production program. The consolidations and eliminations amount includes the elimination of the revenue associated with pipeline transportation services between us and HEP, prior to July 1, 2005.

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. We are reporting EBITDA from continuing operations.

Set forth below is our calculation of EBITDA from continuing operations.

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 Statements of Income.

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