MACKINAC FINANCIAL CORPORATION
REPORTS SECOND QUARTER AND SIX MONTHS 2006 RESULTS OF OPERATIONS

(Manistique, Michigan) — Mackinac Financial Corporation (Nasdaq: MFNC), the bank holding company for mBank (the “Bank”) today announced second quarter 2006 income of $190,000 or $.05 per share compared to a loss of $577,000 or $.17 per share for the second quarter of 2005. Net income for the first six months of 2006 totaled $688,000, or $.20 per share, compared to a loss of $5.818 million, $1.70 per share, for the same period in 2005. The 2006 six months operations include a $600,000 negative provision, recorded in the first quarter, in recognition of improved credit quality. The 2005 results include a penalty of $4.320 million on the prepayment of $48.555 million of the FHLB borrowings. Excluding the provision adjustment and the prepayment penalty, the net income in the first half of 2006 amounted to $88,000, compared to an adjusted loss of $1.498 million for the same period in 2005. The six month 2006 results also include $158,000 of stock option expense, required under the new accounting rules for stock compensation plans, as well as $240,000 of expenses incurred to pursue legal action against the Corporation’s former accountants. The costs associated with the Corporation’s legal action include approximately $185,000 for the retention of and subsequent research performed by an expert witness.

Paul Tobias, Chairman and Chief Executive Officer commented, “The first half of 2006 reflects the Corporation’s growth that has established our foundation for profitability. The balance sheet growth we have attained in the last year has resulted in profitability each month in 2006 at mBank, our principal subsidiary. This balance sheet growth reflects excellent commercial loan production without compromising the bank’s strong credit profile.

Total assets of the Corporation at June 30, 2006 were $352.497 million, up 27.67 percent from the $276.111 million in total assets reported at June 30, 2005. June 30, 2006 total assets were up 18.00 percent from the $298.722 million of total assets at year-end 2005.

Total loans at June 30, 2006 were $283.110 million, up from $204.503 million at June 30, 2005 or a 38.44 percent increase. Total loans at June 30, 2006 increased $43.339 million, or 18.08 percent from year-end 2005 total loans of $239.771 million. Tobias stated, “This loan growth resulted from the successful execution of our market strategy, which is driven by highly qualified commercial lenders, supported by a skilled and responsive credit review team. We have also experienced a resurgence of consumer loan activity in our northern branch locations, which we believe demonstrates our progress in reestablishing trust and confidence within our markets.”

Total deposits of $284.164 million at June 30, 2006 were up 36.74 percent from deposits of $207.814 million on June 30, 2005. Deposits were up $51.532 million, or 22.15 percent from year-end 2005 deposits of $232.632 million. Deposit growth in 2006 includes increases in out of market brokerage deposits totaling $33.588 million with the remaining $17.944 million representing bank core deposit growth of 9.50%. Mr. Tobias added, “Bank deposit growth is a key element of our strategic plan to build franchise value and maintain adequate interest margins. We are continually reviewing our deposit products and offering rates in our efforts to increase core deposits.”

The Bank’s credit quality remains excellent, with total nonperforming assets at June 30, 2006 of $.498 million. Tobias commenting on credit quality stated, “Credit quality is critical. We recognize that with high levels of loan production there is a need for more diligence on the front end credit review process.”

Shareholders’ equity at June 30, 2006 totaled $27.179 million, or $7.93 per share. The Corporation is well capitalized with Tier 1 capital in excess of 8% and total risk-based capital in excess of 10%.

Tobias concluded, “The first six months of 2006 show that we continue to make progress towards our goal of robust profitability, despite the new costs associated with stock options and pursuit of legal action against former accountants of the Corporation. We are optimistic about the remainder of 2006. We remain focused on our plan elements of quality loan production, increasing core deposits, and controlling noninterest expense.
