Exhibit 99.1

Core-Mark Sales Grow by more than 12% in the Third Quarter and 10% Year to Date

South San Francisco, California — November 8, 2010 — Core-Mark Holding Company, Inc. (Nasdaq: CORE), one of the largest marketers of fresh and broad-line supply solutions to the convenience retail industry in North America, announced financial results for the third quarter and nine months ended September 30, 2010.

Third Quarter

Net sales were $1.99 billion for the third quarter of 2010 compared to $1.78 billion for the same period in 2009, a 12.2% increase. On a constant currency basis, net sales increased 11.3%. The primary drivers were increased volume to new and existing customers, excise tax inflation and additional sales to the customers of Finkle Distributor, Inc. (FDI) which the Company recently acquired.

Gross profit for the third quarter of 2010 was $106.1 million compared to $101.9 million for the same period last year. Remaining gross profit, which excludes cigarette holding profits, other tobacco tax gains and LIFO expense, was $109.0 million this quarter compared to $101.6 million in the third quarter of 2009, a 7.3% increase, or a 6.2% increase excluding an immaterial out of period adjustment related to the recognition of deferred vendor income.

The Company’s operating expenses for the third quarter of 2010 increased to $92.5 million compared to $85.8 million in the same quarter in 2009. Operating expenses in this year’s third quarter included $1.2 million of integration costs associated with the FDI acquisition. As a percent of net sales, total operating expenses decreased by 19 basis points.

Net income for the third quarter of 2010 was $8.7 million, or $0.78 per diluted share compared to $11.3 million, or $1.02 per diluted share for the same period in 2009. Diluted earnings per share were impacted by several items, which are reconciled in the attached table. Excluding these items, diluted earnings per share on a non-GAAP basis would have been $0.86 for the third quarter in both years.

“We view the third quarter as decent and consistent with our expectations. Sales remain healthy, particularly in our key strategic categories and we continue to focus on margin improvement,” said Michael Walsh, President and Chief Executive Officer of Core-Mark. “We are extremely pleased in welcoming our new family of customers through the Finkle acquisition. I am very proud of the hard work and success of our folks in achieving an exceptionally smooth integration.”

First Nine Months of 2010

Net sales were $5.41 billion for the first nine months of 2010 compared to $4.88 billion for the same period in 2009, a 10.9% increase. On a constant currency basis, net sales increased 9.0%. The primary drivers were volume increases in the non-cigarette categories, excise tax inflation and cigarette price inflation, in part due to the State Children’s Health Insurance Program legislation.

Gross profit for the first nine months of 2010 was $291.0 million compared to $307.5 million for the same period last year. Cigarette holding profits, net of Federal Excise Tax (FET) and manufacturer’s reimbursements, were $24.5 million in the first nine months of 2009 compared to $3.0 million for the same period this year. Remaining gross profit, which excludes cigarette holding profits, other tobacco tax gains, FET and LIFO expense, was $295.2 million in the first nine months of 2010 compared to $288.6 million in 2009, an increase of $6.6 million. However, the first nine months of this year included approximately $5.6 million less in non-cigarette income mainly in floor stock gains than the same period last year.

The Company’s operating expenses for the first nine months of 2010 increased to $262.3 million compared to $251.2 million for the same period in 2009. This increase included a $3.5 million increase in net fuel expense. In addition, operating expenses this year included $1.0 million related to the settlement of an auto liability claim previously assumed from the Fleming bankruptcy and $1.3 million of integration costs associated with the FDI acquisition. The first nine months of 2009 included $0.9 million in conversion costs related to the New England division. As a percent of net sales, total operating expenses decreased by 30 basis points.

Net income for the first nine months of 2010 was $16.8 million, or $1.47 per diluted share compared to $38.8 million or $3.59 per diluted share for the same period in 2009. Diluted earnings per share were impacted by several items, including the large disparity in cigarette holding profits, which are reconciled in the attached table. Excluding these items, diluted earnings per share on a non-GAAP basis would have been $1.73 for the first nine months this year compared to $2.09 in the first nine months of 2009.

Guidance for 2010

The Company reiterated its annual sales guidance of $7.1 billion for 2010, including expected sales from its recently announced FDI acquisition. However, management lowered its expectation for capital expenditures from $19 to $17 million for 2010.

SEC Regulation G — Non-GAAP Information

This press release includes non-GAAP diluted earnings per share. We believe this non-GAAP financial measure provides meaningful supplemental information for investors regarding the performance of our business and facilitates a meaningful period to period evaluation of our diluted earnings per share. Management uses this non-GAAP financial measure in order to have comparable financial results to analyze changes in our underlying business. This non-GAAP measure should be considered as a supplement to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP.

Safe Harbor

Except for historical information, the statements made in this press release are forward-looking statements made pursuant to the safe-harbor provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are based on certain assumptions or estimates, discuss future expectations, describe future plans and strategies, contain projections of results of operations or of financial conditions or state other forward-looking information. Our ability to predict results or the actual effect of future plans or strategies is inherently uncertain.

Although we believe that the expectations reflected in such forward-looking statements are based on reasonable assumptions, actual results and performance could differ materially from those set forth in the forward-looking statements. Forward-looking statements in some cases can be identified by the use of words such as “may,” “will,” “should,” “potential,” “intend,” “expect,” “seek,” “anticipate,” “estimate,” “believe,” “could,” “would,” “project,” “predict,” “continue,” “plan,” “propose” or other similar words or expressions. These forward-looking statements are based on the current plans and expectations of our management and are subject to certain risks and uncertainties that could cause actual results to differ materially from historical results or those discussed in such forward-looking statements.

Factors that might cause or contribute to such differences include, but are not limited to, our dependence on the convenience retail industry for our revenues; uncertain economic conditions; competition; price increases; our dependence on relatively few suppliers; the low-margin nature of cigarette and consumable goods distribution; certain distribution centers’ dependence on a few relatively large customers; competition in the labor market; product liability claims and manufacturer recalls of products; fuel price increases; our dependence on our senior management; our ability to successfully integrate acquired businesses; currency exchange rate fluctuations; our ability to borrow additional capital; governmental regulations and changes thereto, including the Family Smoking Prevention and Tobacco Control Act which was signed into law in June 2009 and granted the U.S. federal Food & Drug Administration the authority to regulate the production and marketing of tobacco products in the U.S.; earthquake and natural disaster damage; failure or disruptions to our information systems; a greater decline than anticipated in cigarette sales volume; our ability to implement marketing strategies; our reliance on manufacturer discount and incentive programs; tobacco and other product liability claims; and competition from sales of deep-discount cigarette brands and illicit and other low priced sales of cigarettes. Refer to the “Risk Factors” section of our Annual Report on Form 10-K for the year ended December 31, 2009 filed with the SEC on March 12, 2010 and Part II, Item 1A, “Risk Factors” of any quarterly report on Form 10-Q subsequently filed by us. Except as provided by law, we undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.
