FIRSTBANK CORPORATION DECLARES STOCK DIVIDEND

Alma, Michigan (FBMI) – Thomas R. Sullivan, President and Chief Executive Officer of Firstbank Corporation, announced that a 5% stock dividend will be paid December 31, 2003 to shareholders of record as of December 18, 2003.

Mr. Sullivan stated, “This is the twelfth consecutive year Firstbank Corporation has declared a 5% stock dividend, which is in addition to the 2 for 1 stock splits issued in 1993 and 1998. While quarter-to-quarter earnings comparisons currently are being affected by the end of the mortgage refinance boom, the stock dividend is consistent with the underlying earnings power of the company and the strong capital position.” Sullivan continued, “The Board of Directors is pleased to share these strengths with our shareholders. Additionally, cash dividends, including the effect of stock dividends and splits, have increased at a compound annual growth rate of 11% per year over the past five years.”

Firstbank Corporation, headquartered in Alma, Michigan is currently a five bank financial services company with assets of $765 million and 35 banking offices located in central and northeast Michigan. Bank subsidiaries include: Firstbank – Alma; Firstbank (Mt. Pleasant); Firstbank – West Branch; Firstbank – Lakeview: and Firstbank – St. Johns.

Firstbank Corporation Announces Update to Share Repurchase Program

Alma, Michigan (FBMI) – Thomas R. Sullivan, President and Chief Executive Officer of Firstbank Corporation, announced the authorization by Firstbank Corporation’s Board of Directors for the continuation of the company’s common stock repurchase program announced on July 23, 2002.

In the fourth quarter of 2003, through November 21, the company has repurchased 72,900 shares. Combined with expenditures for these share repurchases and those disclosed previously, the company has spent approximately $8.2 million of the $10 million previously authorized. The update announced today will re-establish authorization to repurchase shares for an aggregate amount of up to $10 million from this point forward.

Mr. Sullivan stated, “The updated authorization allows shares to be repurchased from time to time in keeping with the company’s capital needs and desire to maintain a ‘well capitalized’ regulatory capital rating. We continue to have growth objectives and expectations, and plan to retain appropriate capital in the company to support growth opportunities.” Sullivan continued, “Firstbank Corporation plans to continue to rely primarily on open market purchases using selected brokerage firms, on a rotating basis, to conduct its share repurchase activity.”

The timing and amount of share repurchases will be determined by the company’s management based on its evaluation of market and economic conditions and other factors. The company reported that the repurchased shares will be available for use in connection with the company’s stock option plans, employee stock purchase and other stock benefit plans, and for general corporate purposes, including acquisitions.
