MACKINAC FINANCIAL CORPORATION
REPORTS FIRST QUARTER 2011 RESULTS

(Manistique, Michigan) — Mackinac Financial Corporation (Nasdaq: MFNC), the bank holding company for mBank (the “Bank”) today announced first quarter 2011 income of $.256 million or $.07 per share compared to net income of $3.526 million, or $1.03 per share for the first quarter of 2010. Operating results for the first quarter of 2010 included the recognition of a $3.500 million deferred tax benefit related to NOL carry-forwards. The Corporation’s primary asset, mBank, recorded net income of $.529 million

Some highlights for the quarter included:

• Nonperforming assets at the end of the first quarter of 2011 totaled $15.045 million, a reduction of $1.080 million from 2010 year end balances.

• In the first quarter of 2011, the corporation did not record a provision for loan losses as compared to the $.900 million provision recorded in the first quarter of 2010.

• ORE write-downs/gains and losses of $.467 million

• Core deposit growth of $25.024 million primarily in transactional accounts, accounting for $17.743 million of this growth.

• A stable and improving net interest margin of 3.92% for the quarter.

• SBA/USDA loan sale premium income of $.236 million with a solid pipeline of new loans for sale entering into the second quarter which should enable the company to exceed first quarter totals. We still see premium pricing in the 108% to 110% range on these transactions.

Margin Analysis

Net interest margin in the first quarter of 2011 increased to $4.141 million, 3.92%, compared to $4.022 million, or 3.51%, in the first quarter of 2010. The interest margin increase was largely due to decreased funding costs. Kelly W. George, President and Chief Executive Officer of mBank, stated, “In the first quarter of 2011, we experienced continued margin improvement from decreased rates on deposit funding, increases in low cost transactional accounts, and also our disciplined loan pricing, which can include floor rates with regard to variable rate loans. We expect our margin to improve as we progress through the year with increased funding of new loans and further repayment of maturing brokered deposits.”

Loans and Non-performing Assets

Total loans at March 31, 2011 were $374.609 million, a .72% decrease from the $377.311 million at March 31, 2010 and down $8.477 million from year-end 2010 total loans of $383.086 million. George stated, “Loan growth in the first quarter was impacted by normal principal reduction and pay-downs. The $8.477 million in reductions included $2.384 million in SBA loan sales, and the move of $.800 million of nonperforming loans to OREO, along with a reduction of $1.4 million on another nonperforming loan relationship that was sold. Our first quarter new loan production was satisfactory given the seasonality of our business where the first quarter routinely is the slowest. In the first quarter, we had $16.8 million of production occurring in all regions, including $4.9 million in secondary market mortgage production. Our strongest region was the Upper Peninsula with $11.4 million total production.

The decrease in nonperforming assets in the first quarter is the result of aggressive remediation of nonperforming assets, problem borrowers and related workout programs. George, commenting on credit quality, stated “We continue to aggressively market our OREO properties and believe our aggressive write-downs reflect current market values, and will result in sales later this year. We remain highly focused on overall asset quality metrics given the still challenging overall Michigan economy but believe that things have begun to stabilize. We are encouraged by our Texas Ratio of 24.96% for the quarter, which is among the lowest of the 15 largest public banks headquartered in Michigan.”

Deposits

Total deposits of $400.783 million at March 31, 2011 were down 1.09% from deposits of $405.212 million on March 31, 2010 due to decreased levels of brokered deposits, which declined from $138.812 million on March 31, 2010, to $63.342 million on March 31, 2011. First quarter 2011 deposits were up $14.004 million from year-end 2010 deposits of $386.779 million. The overall increase in deposits for the first quarter of 2011 is comprised of a decrease in noncore deposits of $11.020 million which was offset with increased core deposits of $25.024 million. George, commenting on the increased core deposits, stated, “In the first quarter of 2011, we continued to grow core deposits at a steady rate. We will remain focused on this as a primary strategic objective to reduce our overall dependency on wholesale funding sources for future margin improvements and decreased regulatory costs.”

Noninterest Income/Expense

Noninterest income, at $.577 million in the first quarter of 2011, decreased $.230 million from the first quarter 2010 level of $.807 million. Noninterest income in the first quarter of 2010 includes $.215 million of security gains which the Corporation does not consider recurring or core earnings provider. The other most significant decrease for the 2011 first quarter was fees on deposit accounts, due mostly to lower overdraft fees in 2011, a trend that appears to be industry wide given heightened regulatory scrutiny, pending regulations and customers being more aware and diligent in managing their accounts.

Noninterest expense totaled $4.059 million in the first quarter of 2011, an increase of $.430 million, or 11.85% from the first quarter of 2010. Increased expenses in the first quarter continue to reflect the added cost of aggressive nonperforming asset remediation, along with an increase in FDIC insurance premiums of $.063 million. The expenses related to nonperforming assets were primarily write-downs and gains/losses on OREO of $.467 million. The Corporation continues to look for ways to control costs and remains below peer level in terms of salary and benefits and total operating expenses as a percentage of total assets.

Assets and Capital

Total assets of the Corporation at March 31, 2011 were $492.790 million, down 1.92% from the $502.427 million reported at March 31, 2010. First quarter 2011 total assets were up 2.94% from the $478.696 million of total assets at year-end 2010. Common Shareholders’ equity at March 31, 2011 totaled $43.340 million, or $12.67 per share, compared to $48.160 million, or $14.08 per share on March 31, 2010. The Corporation and the Bank are both “well-capitalized” with Tier 1 Capital at the Corporation of 9.70% and 8.54% at the Bank.

Paul D. Tobias, Chairman and Chief Executive Officer, concluded, “We believe that 2011 will be the year where MFNC begins to demonstrate the earning capability of the franchise as the credit environment and our credit metrics improve. In the 2011 first quarter we experienced good growth in core deposits. We expect good loan growth for the remainder of 2011, which will translate into fee income from sales of SBA/USDA loans, along with good balance sheet growth to enhance our net

interest margin. We have also begun to explore the merits of the Small Business Loan Fund as an inexpensive temporary source of capital and a source of repayment of our TARP funding.”
