Subsidiary Huron Valley State Bank Opens.
Shareholders’ Rights Offering Completed.                                 For Immediate Release

        CLARKSTON, Mich., Feb. 3, 2006 — Clarkston Financial Corporation (OTCBB: CKSB), the holding company for Clarkston State Bank and Huron Valley State Bank, posted net income of $102,000, or $0.09 per diluted share, for the fourth quarter, and a net loss of $24,000, or $0.02 per diluted share, for the 12-months ended December 31, 2005, Edwin L. Adler, Board Chairman, and J. Grant Smith, President, jointly announced today.

        The 2005 results compare with net income of $327,000, or $0.31 per diluted share, for Q4-2004, and net income of $1,277,000, or $1.20 per diluted share, for all of 2004.

        Clarkston Financial Corporation is the holding company for Clarkston State Bank and Huron Valley State Bank. Clarkston State Bank opened in January 1999 and operates five branches and one loan center in Clarkston, Waterford, and Independence Township. After a successful rights offering and capital raising campaign Huron Valley State Bank opened in Milford, Mich., in August 2005. Clarkston Financial Corp. owns 55% of the 820,000 common shares outstanding, with Milford-area investors owning the balance.

        “We have not lost momentum. We saw good top-line growth, but our earnings were impaired by non-recurring start-up and operating costs of $590,000 (equal to $0.47 per diluted share) for our new subsidiary Huron Valley State Bank, and a loss from operations of $295,000 (equal to $.23 per diluted share) from our investment in our new mortgage operation,” Mr. Adler said.

        Operating results were also negatively affected by increases in the loan loss provision, which was increased to $104,000 for Q4-2005 and $1,367,000 for all of 2005. The provision expense was $35,000 for Q4-2004 and $330,000 for all of 2004. The increases were necessitated by a small number of loans.

        Despite the net loss for the year, most income metrics were positive. Net interest income rose 12% for Q4 and 18% for the year, reflecting loan growth and improvement in NIM. Noninterest income was off 44% for the quarter, from lower mortgage fees and gains from the sale of mortgages, but up 18% for the full year, from higher bank charges and fees.

        At the close of the year, assets were up 20% to $195,576,000, loans jumped 19% to $133,544,000, and deposits totaled $161,332,000 – up 21% despite tough competition and the rising interest-rate environment.

        Mr. Smith said, “We are moving forward with implementing our strategic objectives and growth plans. We are committed to the communities that we serve and we are not sidetracked at all as a result of our financial performance for 2005. The non-recurring, one time provisions made for a small number of bad credits required us to add to our loan-loss reserve during the year. Moreover, this performance was exacerbated by onetime costs for the start-up of the new Bank. Going forward, we expect the new Bank to continue on its planned growth path throughout 2006, and we’re looking for high single-digit top-line growth and a strong return to profitability.”
