Exhibit 99.1

ALLEGHANY CORPORATION REPORTS 2010 SECOND QUARTER RESULTS — STOCKHOLDERS’ EQUITY PER COMMON SHARE INCREASES 2.1 PERCENT SINCE 2009 YEAR END

     NEW YORK, NY, August 5, 2010 — Stockholders’ equity per common share of Alleghany Corporation (NYSE-Y) at June 30, 2010 was $306.91, an increase of 2.1% from stockholders’ equity per common share of $300.69 at December 31, 2009 (all as adjusted for the stock dividend declared in February 2010), Weston M. Hicks, President and chief executive officer of Alleghany, announced today. The increase in stockholders’ equity per common share primarily reflects earnings in the first half of 2010, partially offset by a negative total return on Alleghany’s equity portfolio for the six month period. Consolidated cash and invested assets of approximately $4.4 billion at June 30, 2010 were essentially unchanged from December 31, 2009.

     Alleghany’s 2010 second quarter net earnings were $66.3 million, or $7.41 per common share (presented on a basic basis throughout), compared with net earnings of $46.0 million, or $5.01 per common share, in the second quarter of 2009. For the first six months of 2010, net earnings were $124.4 million, or $13.85 per common share, compared with net earnings of $90.6 million, or $9.73 per common share in the first six months of 2009. Net earnings amounts include the following components:

(1)	Alleghany Insurance Holdings LLC (“AIHL”) the holding company for Alleghany’s property and casualty and surety insurance operating units consisting of RSUI Group, Inc. (“RSUI”), Capitol Transamerica Corporation and Platte River Insurance Company (collectively, “CATA”) and Pacific Compensation Corporation (“PCC”), formerly known as Employers Direct Corporation, as well as AIHL Re LLC (“AIHL Re”).
(2)	Represents net premiums earned less loss and loss adjustment expenses and commission, brokerage and other underwriting expenses, all as determined in accordance with GAAP, and does not include net investment income, net realized capital gains, other-than-temporary impairment losses or other income, less other expenses. Please refer to “Comment on Regulation G” elsewhere herein.
(3)	Reflects impairment charges for unrealized losses related to Alleghany’s investment portfolio that are required to be charged against earnings as realized losses.
(4)	Corporate activities consist of Alleghany Properties Holdings LLC, Alleghany’s investments in Homesite Group Incorporated (“Homesite”) and ORX Exploration, Inc. (“ORX”), and corporate activities at the parent level.

     Results for the second quarter and first six months of 2010, compared with the corresponding 2009 periods, primarily reflect an increase in AIHL’s pre-tax earnings, partially offset by pre-tax net losses at Corporate activities. The increase in AIHL’s pre-tax earnings in the second quarter and first six months of 2010 primarily reflects:

• a decrease in PCC’s underwriting loss primarily reflecting no adverse development recorded by PCC in the 2010 periods, compared with $34.5 million of adverse reserve development recorded in the first six months of 2009 (all of which was recorded in the second quarter);

• an increase in net realized capital gains, primarily due to gains on sales of certain energy sector equity securities; and

2

• a decrease in other-than-temporary impairment losses due primarily to improved equity market conditions since the 2009 first quarter.

The pre-tax net losses at Corporate activities in the second quarter and first six months of 2010 primarily reflect a substantial decrease in net realized capital gains as a result of the absence of sales of common stock of Burlington Northern Santa Fe Corporation in such periods, compared with significant sales of such common stock during the second quarter and first six months of 2009.

     Mr. Hicks commented that “The first half of 2010 saw the continuation of a competitive property and casualty insurance market and a challenging investment environment. Despite continued pricing pressure, RSUI and CATA produced underwriting profits in the first half of 2010 and will continue to strive to maintain disciplined pricing in this environment. Pacific Compensation continues to execute on its plan to re-emerge as an agency carrier during 2010. On a consolidated basis, the total return on our investments, excluding other invested assets consisting primarily of our Homesite and ORX investments, was 2.3% in the first six months of 2010, with our fixed income portfolio providing a total return of 3.7% and our equity portfolio providing a negative total return of 7.5%, slightly behind the S&P 500’s negative total return of 6.6% for the same period.”

     Information regarding the pre-tax results of AIHL’s operating units is attached asExhibit A. During the first six months of 2010, Alleghany purchased in the open market an aggregate of 207,133 shares of its common stock for approximately $59.8 million, at an average price per share of $288.78 (such share and average price amounts are not adjusted for the stock dividend declared in February 2010), pursuant to the previously announced authorization by its Board of Directors to repurchase up to $300.0 million of Alleghany’s common stock. In July 2010, the Board of Directors authorized Alleghany to repurchase additional shares of its common stock, at such times and at such prices as management may determine advisable, up to an aggregate of $300.0 million upon completion of the current program. As of August 2, 2010, Alleghany had 8,833,790 shares of its common stock outstanding, adjusted to reflect the stock dividend declared in February 2010.

     Additional information regarding Alleghany’s results for the second quarter and first six months of 2010, including management’s discussion and analysis of Alleghany’s financial condition and results of operations for the second quarter and first six months of 2010, is contained in Alleghany’s Quarterly Report on Form 10-Q for the period ended June 30, 2010, to be filed with the U.S. Securities and Exchange Commission on or about August 5, 2010. The Form 10-Q will be available on Alleghany’s website at www.alleghany.com and on the Securities and Exchange Commission’s website at www.sec.gov. Readers are urged to review the Form 10-Q for a more complete discussion of Alleghany’s financial performance.

Comment on Regulation G

     This press release includes certain non-GAAP financial measures. The reconciliations of such measures to the most comparable GAAP financial measures are included inExhibit A of this press release. Throughout this press release Alleghany presents its operations in the way it believes will be most meaningful and useful to the investing public and others who use such information in evaluating Alleghany’s results.

3

     Alleghany shows earnings before income taxes (a GAAP financial measure), as well as underwriting profit (a non-GAAP financial measure), which is earnings before income taxes, adjusted to exclude the impact of net investment income, net realized capital gains, other-than-temporary impairment losses and other income, less other expenses. The presentation of underwriting profit is intended to enhance the understanding of AIHL’s insurance operating units’ operating results by highlighting earnings attributable to their underwriting performance.

     With respect to AIHL’s insurance operating units, earnings before income taxes may show a profit despite an underlying underwriting loss. If underwriting losses persist over extended periods, an insurance company’s ability to continue as an ongoing concern may be at risk. Investors should consider the non-GAAP measures contained herein in addition to, and not as a substitute for, measures of financial performance prepared in accordance with GAAP.

(1)	Represent components of total revenues.
(2)	Commission, brokerage and other underwriting expenses represent commission and brokerage expenses and that portion of salaries, administration and other operating expenses attributable to underwriting activities, whereas the remainder constitutes other expenses.
(3)	Represents net premiums earned less loss and loss adjustment expenses and commission, brokerage and other underwriting expenses, all as determined in accordance with GAAP, and does not include net investment income, net realized capital gains, other-than-temporary impairment losses, other income and other expenses. Underwriting profit does not replace net earnings determined in accordance with GAAP as a measure of profitability; rather, we believe that underwriting profit, which does not include net investment income, net realized capital gains, other-than-temporary impairment losses, other income and other expenses, enhances the understanding of AIHL’s insurance operating units’ operating results by highlighting net earnings attributable to their underwriting performance. With the addition of net investment income, net realized capital gains, other-than-temporary impairment losses, other income and other expenses, reported pre-tax net earnings (a GAAP measure) may show a profit despite an underlying underwriting loss. Where underwriting losses persist over extended periods, an insurance company’s ability to continue as an ongoing concern may be at risk. Therefore, we view underwriting profit as an important measure in the overall evaluation of performance.
(4)	Loss and loss adjustment expenses divided by net premiums earned, all as determined in accordance with GAAP.
(5)	Commission, brokerage and other underwriting expenses divided by net premiums earned, all as determined in accordance with GAAP.
(6)	The sum of the loss ratio and expense ratio, all as determined in accordance with GAAP, representing the percentage of each premium dollar an insurance company has to spend on losses (including loss adjustment expenses) and commission, brokerage and other underwriting expenses.
