PRESS RELEASE

Sound Credit Union, a leading not-for-profit financial institution serving Washington State, and Washington Business Bank (OTCPK: WBZB), a premier commercial bank headquartered in Olympia, Washington, announced today they have entered into a definitive agreement in which Sound Credit Union will acquire Washington Business Bank. The transaction is structured as a purchase agreement with Sound Credit Union purchasing substantially all assets and assuming substantially all liabilities of Washington Business Bank.

The acquisition helps Sound Credit Union grow its presence in the Olympia market, diversify its assets, and add talent and expertise. Washington Business Bank customers will become members of Sound Credit Union with full access to all Sound Credit Union’s products and services.

“Washington Business Bank has served as a cornerstone for local business owners for more than twenty years,” said Don Clark, President and CEO of Sound Credit Union. “We look forward to providing these new members the same level of excellent service, an expanded suite of products and services, as well as all the benefits membership in a credit union brings to help their businesses and families thrive.”

The transaction has been unanimously approved by the boards of directors of both institutions. Following the completion of the transaction, Washington Business Bank will liquidate and dissolve and distribute its remaining assets to its shareholders. When finalized, the combined institution will have approximately $3.0 billion in assets, $2.3 billion in loans, $2.5 billion in deposits, serve more than 170,000 members, and will have 27 branches throughout King, Pierce, Snohomish, and Thurston Counties. In connection with the transaction, the shareholders of Washington Business Bank will receive approximately $34.00 – $36.00 in cash for each share of Washington Business Bank common stock, subject to certain adjustments at closing.

Washington Business Bank provides deposit, lending, and cash management services to their business clients as well as personal deposits and safe deposit boxes for retail consumers. Once becoming Sound Credit Union members, those customers can expect expanded borrowing, saving, investment, and insurance options along with additional account management and support tools.

“Since our founding, our mission has been to work alongside small business owners across Washington to help them become more successful,” said Jon M. Jones, President and CEO of Washington Business Bank. “We know these owners will find the same level of partnership with the Sound Credit Union team for years to come.”

The transaction is expected to be completed in the fourth quarter of 2024, subject to receiving all regulatory approvals, Washington Business Bank shareholder approval, and other customary closing conditions.

Once complete, Sound Credit Union will continue to operate Washington Business Bank’s current location in downtown Olympia at 5^th Avenue and Franklin Street, providing Sound Credit Union members with two full-service Olympia locations including its branch at Martin Way and Lilly Road.
