EXHIBIT 99.1 [MERCANTILE BANK CORPORATION LOGO] FOR FURTHER INFORMATION: AT MERCANTILE BANK CORPORATION: FOR MEDIA: Gerald R. Johnson, Jr. Charles Christmas Linda Margolin Chairman & CEO Chief Financial Officer Margolin & Associates, Inc. 616-406-3700 616-406-3750 216-765-0953 gjohnson@mercbank.com cchristmas@mercbank.com lmm@margolinIR.com MERCANTILE BANK CORPORATION ANNOUNCES 2004 FISCAL YEAR NET INCOME OF $13.7 MILLION, UP 37.0% FOURTH QUARTER NET INCOME ROSE 48.9% WYOMING, MICH., January 12, 2005 -- Mercantile Bank Corporation (Nasdaq: MBWM) reported net income for the fiscal year ended December 31, 2004 of $13.7 million, up 37.0 percent from the $10.0 million reported for the fiscal year ended December 31, 2003. Earnings for 2004 include an $845,000 ($548,000 after-tax) write-off associated with the unamortized balance of issuance costs related to the redemption of the $16.0 million trust preferred offering issued in 1999. Excluding this one-time charge, earnings were $14.3 million, a 42.5 percent increase over 2003. Reported diluted earnings per share were $1.87 compared with $1.61 reported for the prior fiscal year, an increase of 16.1 percent. Excluding the one-time charge, earnings per share were $1.94, an increase of 20.5 percent. Per share results reflect a common stock offering completed in the fourth quarter of 2003, which increased average fully diluted shares outstanding by 1.1 million, or 18.3 percent. For the fourth quarter of 2004, Mercantile reported net income of $4.5 million, up 48.9 percent from the $3.0 million reported in the fourth quarter of 2003. Reported diluted earnings per share were $0.61 compared with the $0.42 reported for the prior-year period, a 45.2 percent increase. Gerald R. Johnson, Jr., Chairman and CEO, commented, "2004 was another record year for Mercantile. Our company's strong performance continues to be driven by commercial loan growth; we have been uniquely successful lending to small and mid-sized businesses attracted by our lending expertise and high service levels. West Michigan is well-known for its entrepreneurial environment, as is Mercantile Bank of West Michigan. We have structured our product line, hired our staff, and built an infrastructure to provide our small business leaders with the best in banking. Our earnings and profitability growth reflect our success at this strategy. "We passed the $1.5 billion mark in assets during the fourth quarter of 2004. In anticipation of our continuing growth needs, we added an additional $16.0 million in trust preferred securities to our capital base, and we strengthened our physical infrastructure through the investment in a new headquarters building and Holland branch facility. The Holland facility opened in November, 2004 and the headquarters building is scheduled to be completed by May, 2005. These moves should position us for a strong business environment in 2005." Total revenue, comprised of net interest income and non-interest income, was $46.7 million for the 2004 fiscal year, an increase of 31.0 percent over the $35.7 million earned during 2003. Mr. Johnson noted, "Effective management of our net interest margin allowed us to benefit from the more favorable interest rate environment, although strong loan growth continues to be the main driver of our revenue growth." Net interest income increased 35.7 percent to $42.4 million, reflecting a combination of 31.6 percent growth in average earning assets and an eight basis point improvement in the net interest margin to 3.30 percent. Non-interest income for 2004 was $4.3 million, slightly below the $4.4 million reported for 2003. The $545,000 decline in residential mortgage fees in 2004 was replaced by increased income in virtually all other categories. Total revenue for the fourth quarter of 2004 was $13.2 million, an increase of 31.4 percent over the $10.0 million earned in the prior-year period. Net interest income increased 35.2 percent to $12.1 million as a result of a 28.0 percent increase in average earning assets and a 17 basis point increase in the net interest margin to 3.43 percent. Non-interest income for the fourth quarter of 2004 was $1.1 million, virtually unchanged from the prior-year level. Revenue growth continues to outpace expense growth. Non-interest expense for the 2004 fiscal year was $23.2 million, an increase of 28.4 percent over the prior-year period. Excluding the one-time write-off of trust preferred issuance costs during the third quarter of 2004, non-interest expense increased 23.7 percent. Salaries and benefits, up 22.7 percent, represented the largest increase in non-interest expense, and primarily reflected a 20.5 percent increase in FTE employees. Mercantile's efficiency ratio improved to 49.64 percent for 2004 compared with 50.66 percent for 2003. Excluding the one-time write-off, its 2004 efficiency ratio was 47.84 percent. Non-interest expense for the fourth quarter of 2004 was $6.2 million, an increase of 26.7 percent over the prior-year period. Salaries and benefits, the largest component of that increase, grew 15.8 percent. Non-interest expense was increased by $386,000 relating to the purchase of rehabilitation tax credits. The transaction resulted in a $414,000 reduction in federal income tax expense, and enabled Mercantile to provide additional support to a valued customer. Fourth quarter efficiency improved to 47.22 percent compared with 48.98 percent for the year-ago quarter. Asset quality continues to be excellent. Mr. Johnson commented, "As a West Michigan-based community bank, we excel in our knowledge of our local customers and our marketplace. Superb credit administration and lending expertise are core competencies at Mercantile and an integral component of our commercial lending strategy. Our low level of loan losses continues to contribute to our growing profitability levels." Net charge-offs for 2004 were $1.2 million, or 0.10 percent of average loans. Non-performing assets were 0.19 percent of total assets at December 31, 2004, compared with 0.20 percent at September 30, 2004, and 0.15 percent at December 31, 2003. Loan and lease loss reserves were $17.8 million, or 1.35 percent of total loans and leases at December 31, 2004. Total assets were $1.5 billion at December 31, 2004, an increase of $332.8 million, or 27.7 percent, from last year. Loans rose $281.2 million, or 27.1 percent, during the same time period, primarily funded by a $256.3 million, or 28.4 percent, increase in deposits. Non-interest bearing deposits rose 32.9 percent, to $101.7 million. Shareholders' equity at December 31, 2004 was $141.6 million, a twelve-month increase of $11.4 million, or 8.8 percent. Total shares outstanding at quarter end were 7,192,461. Mercantile's total risk-based capital ratio at quarter-end was 13.03 percent. Mr. Johnson concluded, "Our business model, with its focus on commercial lending and quality service delivered efficiently, has worked exceptionally well in the Western Michigan market. We look forward to a continuation of that success in 2005." About Mercantile Bank Corporation Mercantile Bank Corporation is the bank holding company for Mercantile Bank of West Michigan.
