Nationwide Insurance and Harleysville Insurance Agree to Combine

Strategic combination will expand Nationwide’s distribution footprint, increase its P&C commercial lines business and provide a broader product portfolio for agents and customers

Nationwide Mutual Insurance Company (“Nationwide Mutual”) and Harleysville Mutual Insurance Company (“Harleysville Mutual”) and Harleysville Group Inc. (NASDAQ:HGIC - News) (“Harleysville Group”) today announced that they have entered into a definitive agreement under which Harleysville will combine with Nationwide. Under the terms of the agreement, Harleysville Mutual policyholders will become policyholders and members of Nationwide Mutual and Nationwide Mutual will acquire all of the publicly held shares of common stock of Harleysville Group for $60.00 per share in cash.

Joining with the Harleysville companies will further strengthen and diversify Nationwide’s business, expand its distribution footprint, and increase its property and casualty (“P&C”) commercial lines business. The combined organization, which will have an estimated net surplus of more than $13.5 billion and over $16 billion in annual direct written premiums, will be well positioned for growth.

“This combination brings together two best-in-class companies that share a mutual heritage and a focus on meeting the long-term needs of our policyholders,” said Steve Rasmussen, Chief Executive Officer of Nationwide. “With Harleysville’s expertise in commercial lines and Nationwide’s complementary geographic distribution, there will be a substantial opportunity to increase market share, while also providing our combined agents and customers access to a broader portfolio of insurance, financial and banking products.”

“Harleysville is very pleased to join forces with Nationwide in a transaction that will enable us to expand our business for our independent agency partners and to enter important new markets from a position of even greater strength,” said Michael Browne, President and Chief Executive Officer of Harleysville. “We are proud of our 96-year history and the longstanding success we and our independent agencies have enjoyed as a result of our partnership with one another. We remain committed to our trusted independent agency partners and to the independent agency system. I am confident that the combined organization will allow us to deliver the best products and services available to grow our independent agents’ books of business with us more effectively and efficiently. We look forward to working with Nationwide’s talented team and are very pleased that Nationwide has committed to maintaining the Harleysville brand.”

Mr. Rasmussen added, “This transaction supports and accelerates our strategy and mission to make it easy for agents and customers to do business with Nationwide however they desire. Nationwide has invested heavily in independent agent distribution, beginning with our acquisition of Allied Insurance in 1998. While the Harleysville transactions would expand our independent agency distribution nationally, Nationwide also maintains a strong commitment to its exclusive agency partners. We’re committed to making strategic investments in all of our distribution channels as each is vital and contributes to our mission.”

Transaction Structure and Terms

Under the terms of the agreement, Harleysville Mutual would merge into Nationwide Mutual and Harleysville Group, Harleysville Mutual’s publicly traded subsidiary, would be merged with a newly formed subsidiary of Nationwide Mutual. Each public stockholder of Harleysville Group would receive $60.00 per share in cash. Upon closing, Harleysville Group would be a wholly owned subsidiary of Nationwide.

Through the combination, Harleysville will join Nationwide’s P&C independent agency business unit under the Harleysville brand. In addition, Harleysville’s current headquarters in Harleysville, PA, will serve as an integral part of the combined company’s national, independent agency-based platform. Mr. Browne will become the President and Chief Operating Officer of the Harleysville company.

The transactions are subject to customary closing conditions, including, among others, approvals from stockholders of Harleysville Group; policyholders of Harleysville Mutual and Nationwide Mutual; the Pennsylvania Insurance Department; the Ohio Department of Insurance; and various other regulatory bodies.
