Exhibit 99.1

Fremont Michigan InsuraCorp Agrees to be Acquired by

Auto Club Insurance Association

Fremont, Mich., and Dearborn, Mich. — April 18, 2011—Fremont Michigan InsuraCorp, Inc. (OTCQB:FMMH), a Michigan-exclusive property and casualty insurer, and Auto Club Insurance Association (ACIA), a Michigan-domiciled reciprocal inter-insurance exchange, today announced that they have entered into a definitive merger agreement. Under the terms of the agreement, ACIA will acquire all of the outstanding shares of Fremont for $36.15 per share in cash, for an aggregate purchase price of approximately $67.7 million.

The $36.15 per share purchase price represents a premium of approximately 35% over the $26.75 per share closing price of FMMH on April 15, 2011, the last trading day prior to today’s announcement. The purchase price equals approximately 1.4 times the GAAP book value of Fremont at Dec. 31, 2010.

Richard E. Dunning, President and CEO of Fremont, said, “This transaction delivers significant value to our shareholders. Additionally, I see this as a positive transaction for our agents, employees and the Fremont community as ACIA plans to maintain Fremont’s franchise and our Fremont, Mich. executive offices, and work with Fremont to increase its independent agency distribution in the state of Michigan and surrounding states. With an A.M. Best Financial Strength Rating of “A” (Excellent), ACIA is one of the most respected insurance companies in Michigan, and our current and future insureds will benefit from the added financial strength and products ACIA is able to provide. I would like to recognize our agents and employees for their dedication and commitment to Fremont, as they are the driving force behind the ongoing success of our company.”

Charles H. Podowski, President and CEO of ACIA, said, “Fremont is a highly regarded brand that enjoys strong connectivity to its independent agents and has a deep commitment to serving its local community. It is a high performing and well-run company, with a sound management team and values similar in many ways to our own. The breadth of Fremont’s product offerings, distribution of business in the western and northern parts of Michigan, long-standing relationships with independent agencies, and robust financial performance will immediately benefit the enterprise. As has been the case with each of our acquisitions, we are confident this transaction will provide longer-term opportunities and possibilities for our business.”

The Board of Directors of Fremont has determined the transaction to be in the best interest of Fremont’s shareholders, unanimously approving the proposed transaction and recommending that Fremont’s shareholders vote to approve the merger. The Board of Governors of ACIA also voted in support of the merger. The transaction is subject to customary closing conditions, including the receipt of regulatory approvals, and approval by a majority of Fremont’s shareholders. There is no financing condition and the purchase price will be made with ACIA’s available cash. The transaction is expected to close in the third quarter of 2011.

Sardar Biglari, Chairman and CEO of Biglari Holdings Inc., holder of approximately 9.7% of the stock of Fremont, voiced support for the transaction, saying “I have enjoyed working with Fremont’s Chairman of the Special Committee in our effort to realize the full value of Fremont’s shares. The merger with ACIA represents a victory for all Fremont stockholders. We applaud the Committee’s efforts.”

Certain other stockholders representing approximately 16% of Fremont’s stock, including Mitchell Partners, L.P., holder of approximately 9.9% of Fremont’s stock, have signed a shareholders agreement committing to vote their shares in favor of the transaction, subject to the terms of the shareholders agreement.

Given the Special Meeting of Shareholders that will be called in the near future, the Board of Directors of Fremont has decided to delay the 2011 Annual Meeting of Shareholders usually held in May. Shareholders will be provided a Notice of the Special Meeting along with proxy materials when the date is set.

Fremont filed its Annual Report on Form 10-K for the year ending Dec. 31, 2010 with the Securities and Exchange Commission (SEC) on March 30, 2011. Investors and security holders may access the Form 10-K document at the SEC’s website, www.sec.gov.
