Exhibit 99

                           MBT FINANCIAL CORP. UPDATES
                          FULL YEAR FINANCIAL GUIDANCE

Monroe, Michigan --MBT Financial Corp. (NASDAQ: MBTF) reported today that it
does not expect its net income per share for the full year to be in the $1.15 to
$1.20 range that was reported following its second quarter earnings
announcement. A recent development with an individual credit relationship
required the company to add $5.5 million to its allowance for loan losses. This
additional provision to the company's allowance for loan losses will negatively
impact the company's earnings for the quarter ended September 30, 2003. The
company expects a reduction in earnings per share of $0.19 for the third quarter
as a result of this additional provision to its allowance for loan losses. The
company now expects its full year earnings per share to be in the $0.95 to $1.00
range. The company plans to announce its third quarter earnings on October 15,
2003.
