Exhibit 99.1 Harleysville Group Reports Third Quarter 2006 Results Third quarter highlights: -- Operating earnings rise 28 percent to $0.69 per share -- Statutory combined ratio improves by 4 points to 98.5 percent -- Strong cash flow drives 14 percent net investment income growth -- Annual dividend increases by 9 percent HARLEYSVILLE, Pa.--(BUSINESS WIRE)--Oct. 26, 2006--Harleysville Group Inc. (NASDAQ: HGIC) today reported diluted operating income of $0.69 per share for the third quarter of 2006, compared to $0.54 per share in the third quarter of 2005. For the nine-month periods, the company reported diluted operating income of $1.94 per share in 2006 and $1.41 per share in 2005. Operating income is a non-GAAP financial measure defined by the company as net income excluding after-tax realized gains and losses on investments, and the cumulative effect of an accounting change, net of income tax. "We're pleased that our third quarter results continue to reflect the ongoing, steady improvement in our operating performance," commented Michael L. Browne, Harleysville Group's president and chief executive officer. "Our statutory combined ratio for the quarter was 98.5 percent--which is 4 points better than a year ago--and we produced an operating return on equity of 12.8 percent. In addition, our operating earnings for the third quarter were $0.69 per share, which is much improved from the $0.54 a share we reported in the third quarter of 2005, and we increased our annual dividend by 9 percent. We continue to maintain our solid capital base and a strong balance sheet, a modest debt-to-capital ratio of 15 percent(1),a high-quality investment portfolio, and a premium-to-surplus ratio of 1.3 to 1--all of which provide the sound financial position necessary for us to write our agents' best business." The company reported diluted net income of $0.69 per share in the third quarter of 2006, compared to $0.54 per share in the third quarter of 2005. There were essentially no realized investment gains in the third quarter of either year. For the nine-month periods, diluted net income was $2.81 per share in 2006 and $1.41 per share in 2005. For the nine months, the company reported $0.84 per share of realized investment gains in 2006, compared to none in 2005. The majority of the realized gains in the nine months of 2006 are the result of actions taken by the company in the second quarter of this year to reduce its holding of equity investments by approximately $120 million as part of its efforts to manage enterprise-wide risk. The first nine months of 2006 also includes an after-tax benefit of $0.03 per share for the cumulative effect of a change in accounting principle resulting from the adoption of Statement of Financial Accounting Standards No. 123R, "Share-Based Payment." This statement requires that the cost resulting from all share-based payment transactions be recognized in the financial statements. Harleysville Group's overall statutory combined ratio(2) was 98.5 percent in the third quarter of 2006, compared to 102.5 percent in the third quarter of 2005. For the nine months, the statutory combined ratio was 98.8 percent in 2006, versus 102.8 percent in 2005. Third quarter net written premiums were $207.3 million in 2006, compared to $206.6 million in the same period in 2005. Net written premiums through nine months were $635.2 million in 2006 and $640.6 million in 2005. Third quarter pretax investment income increased 14 percent to $26.4 million, while after-tax investment income grew 9 percent in the third quarter to $19.2 million. For the nine months, pretax investment income was up 12 percent to $75.3 million, while after-tax investment income rose 8 percent to $55.6 million. Operating cash flow through nine months was $114.0 million in 2006, compared to $115.9 million in 2005. Commercial lines -- Net written premiums in commercial lines were $168.5 million in the third quarter of 2006, up 1 percent from the same period in 2005. For the nine months, net written premiums were essentially unchanged at $526.4 million. The commercial lines statutory combined ratio was 99.5 percent in the third quarter of 2006, versus 104.7 percent in the third quarter of 2005. For the nine months, the statutory combined ratio was 100.4 percent in 2006, compared to 103.9 percent in 2005. Personal lines -- Harleysville Group's personal lines statutory combined ratio was 93.6 percent in the third quarter of 2006, versus 92.8 percent during the third quarter of 2005. For the nine months, the statutory combined ratio was 91.2 percent in 2006, compared to 97.9 percent in 2005. Net written premiums decreased 1 percent to $38.8 million in the third quarter of 2006, and were down 3 percent to $108.7 million through nine months. Outlook -- "Through the balance of 2006, and longer term, we will remain focused on the basics of our business as we seek to consistently produce the quality results we are reporting today--improving earnings, profitable underwriting, operating return on equity over 12 percent and smart growth for the long term--while always maintaining a healthy balance sheet," Browne said. "At the same time, we will not compromise underwriting quality to chase a near-term growth goal. That's especially important in light of current market conditions. Instead, we will remain focused on maintaining our discipline as we seek a sustained overall underwriting profit and long-term improvement in our performance. And, we will continue to work closely with our agency force and rely heavily on them for their assistance in order to position us for further success in 2007 and beyond." Webcast -- The company will host a live Webcast today, October 26, 2006, at 8 a.m. (ET) to discuss its third quarter results. The Webcast and a replay will be available from the Investors section of the company's Web site (www.harleysvillegroup.com). GAAP and non-GAAP financial measures -- The company uses a non-GAAP financial measure called "operating income" that management believes is useful to investors because it illustrates the performance of normal, ongoing operations, which is important in understanding and evaluating the company's financial condition and results of operations. While this measure is utilized by investors to evaluate performance, it is not a substitute for the U.S. GAAP financial measure of net income. Therefore, a reconciliation of this non-GAAP financial measure to the U.S. GAAP financial measure of net income is provided following the Consolidated Statements of Income contained in this release. Management also uses operating income for, among other things, goal setting, determining employee and senior management compensation, and evaluating performance.

(2) "Statutory combined ratio" is a non-GAAP measure of underwriting profitability and is based on numbers determined under statutory accounting practices as filed with state insurance regulators. It is the sum of the ratio of losses to premiums earned plus the ratio of underwriting expenses to premiums written. A ratio of less than 100 percent indicates underwriting profitability. Certain of the statements contained herein (other than statements of historical facts) are forward-looking statements. Such forward-looking statements are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 and include estimates and assumptions related to economic, competitive and legislative developments.

There can be no assurance that future developments will be in accordance with management's expectations so that the effect of future developments on Harleysville Group will be those anticipated by management. Actual financial results including operating return on equity, premium growth and underwriting results could differ materially from those anticipated by Harleysville Group depending on the outcome of certain factors, which may include changes in property and casualty loss trends and reserves; catastrophe losses; the insurance product pricing environment; changes in applicable law; government regulation and changes therein that may impede the ability to charge adequate rates; changes in accounting principles; performance of the financial markets; fluctuations in interest rates; availability and price of reinsurance; and the status of the labor markets in which the company operates.
