Grand River Commerce, Inc. Announces Plans to Suspend Its SEC Reporting

Grandville, MI (June 29, 2012) – Grand River Commerce, Inc. (OTCBB: GNRV), the holding company for Grand River Bank (the “Bank”), announced today that, pursuant to the provisions of the Jumpstart Our Business Startups Act (the “JOBS Act”), its board of directors has approved the filing of a Form 15 with the United States Securities and Exchange Commission (“SEC”) to deregister the Company’s common stock and suspend the Company’s reporting obligations under Sections 12(g) and 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The JOBS Act, which was signed into law on April 5, 2012, increases the threshold under which banks and bank holding companies are permitted to deregister from the Exchange Act from 300 record shareholders to 1,200 record shareholders. The Company has 648 shareholders of record, and therefore qualifies for deregistration.

The Company intends to file the Form 15 on or about June 29, 2012 and expects it to become effective 90 days after its filing, or September 26, 2012. Once the Form 15 is effective, the obligations of the Company to file periodic reports with the SEC, including reports on Forms 10-K, 10-Q and 8-K, as well as proxy materials, will cease.

“The decision to suspend reporting was made after careful consideration of the advantages and disadvantages of continuing as an SEC reporting company. This action should reduce our operating expenses and result in a significant benefit to the Company’s stockholders.” said Robert P. Bilotti, Chairman and CEO of Grand River Commerce, Inc. “Our shareholders will continue to have access to Company performance information on our website and via our publicly available regulatory reports.”

The Company’s common stock is currently quoted on the OTCBB, and the Company anticipates that listing will continue.
