Mackinac Financial Corporation Announces
2008 Results of Operations

((Manistique, Michigan) — Mackinac Financial Corporation (Nasdaq: MFNC), the holding company for mBank, has reported net income of $1.872 million, or $.55 per share, for the year ended December 31, 2008, compared to a net income of $10.163 million, or $2.96 per share, for 2007. Weighted average shares outstanding amounted to 3,422,012 in 2008 and 3,428,695 in 2007.

The 2008 results included the positive effect, $3.475 million of a lawsuit settlement and the negative effect, $.425 million, of a severance agreement. The results for 2007 included the recognition of a $7.500 million deferred tax benefit for NOL and tax credit carryforward and $.470 million of proceeds from the settlement of a lawsuit against the Corporation’s former accountants.

In 2008, we experienced one of the most difficult and trying times in modern banking history. Our results for 2008 were significantly impacted by the current economic environment. The Prime Rate, currently at 3.25% and the overnight investment rates at near zero, provide evidence of the seriousness in which the Federal Reserve Bank views this recession. This historically low interest rate environment made it extremely difficult to maintain adequate interest margins which stymied our ability to generate earnings growth. We are not satisfied with our operating results. In 2008, we focused our efforts on watchful diligence of our current loan portfolio by shoring up potential problem credits, repricing loans to align our returns with both credit and interest rate risks and by pursuing early resolution of nonperforming assets.

5

At 2008 year-end, the Corporation’s loans stood at $370.280 million, an increase of $15.201 million, or 4.3%, from 2007 year-end balances of $355.079 million. Total loan originations in 2008 amounted to $61.6 million. Loan amortization and principal payoffs totaled $51.2 million. A good portion of these payoffs pertained to loan relationships that no longer met our pricing or credit standards. Loan growth was primarily from the Upper Peninsula markets where the economy is more stable.

Total assets of the Corporation at December 31, 2008 were $451.431 million, an increase of $42.551 million, or 10.4% from total assets of $408.880 million reported at December 31, 2007.

Asset quality remains relatively strong when compared to our peers, particularly considering the state of the Michigan economy. Nonperforming loans totaled $4.887 million, or 1.32% of total loans at December 31, 2008. Nonperforming assets at December 31, 2008, were $7.076 million, 1.57% of total assets, compared to $5.234 million or 1.28% of total assets at December 31, 2007. However, we are not immune to the current economic crisis and we are seeing rapid change in Southeast Michigan as the auto industry and manufacturing businesses struggle to survive. This economic risk has caused us to take an extremely hard and cautious look at our entire portfolio of loans in this market and we have been aggressive in our early identification of problem credits. We increased our fourth quarter loan loss provision to provide a specific reserve for one large loan in Southeast Michigan.

Total deposits grew from $320.827 million at December 31, 2007, to $371.097 million at December 31, 2008, an increase of $50.270 million, or 15.7%. This increase is composed of an increase in wholesale brokered deposits of $52.225 million and a decline in bank deposits of $1.955 million. During 2008, we significantly increased our balance sheet liquidity which was funded primarily by issuance of brokered deposits since rates on these deposits were priced lower than in-market bank deposits. We continue to focus our efforts on growing transactional accounts. We have had success in this area as demand, money market and NOW accounts grew from $119.2 million at 2007 year-end to $121.4 million at 2008 year-end. However, overall deposit totals have fallen as we have refused to compete for CDs that are overpriced.

Net interest income for the year ended December 31, 2008 was $12.864 million compared to $13.417 million for the year ended December 31, 2007, a decrease of $.553 million. The margin percentage for 2008 was 3.23% compared to 3.60% in 2007 and 3.51% in 2006. We believe that our margin has seen its low point in December when it fell to 3.01%. During 2008, the prime rate decreased from 7.25% to 3.25%, which created significant margin pressure since a majority of the commercial loan portfolio re-priced downward with each prime rate change, which the majority of the bank’s funding sources had significant lag time in re-pricing. We experienced additional margin pressure due to our brokered deposits, which did not re-price in line with prime rate reductions, due to the overall market liquidity crisis.

We recognize the importance of cost control, especially in times of economic slowdown. Excluding extraordinary items, noninterest expense totaled $12.1 million in 2008 compared to $12.1 million in 2007 and $11.6 million in 2006. Salaries and benefits were reduced from $6.8 million in 2007 to $6.5 million in 2008. Assets per employee totaled $4.6 million

6

Shareholders’ equity totaled $41.552 million at December 31, 2008, compared to $39.321 million at the end of 2007, an increase of $2.231 million. This increase reflects consolidated net income of $1.872 million, the capital contribution impact of stock options and also the increase in equity due to the increase in the market value of held-for-sale investments, which amounted to $.385 million and the purchase of odd lot shares for $.110 million. The book value per share at December 31, 2008, amounted to $12.15 compared to $11.47 at the end of 2007.

Late in 2008, the corporation elected to apply for $11 million in equity participation under the Troubled Asset Relief Program (TARP). We have received preliminary approval from the US Treasury Department and are now evaluating the merits of the program. Participation in this program would provide additional capital for future growth during a time when other sources for additional capital are scarce and expensive.
