Item 8.01 Other Events

Bluevine Relationship

On September 28, 2026, Bluevine, Inc. (“Bluevine”), a financial technology partner of Coastal Community Bank (the “Bank”), announced that it entered into a definitive agreement to be acquired by Valley National Bancorp, the parent company of Valley Bank (the “Transaction”). The Transaction remains subject to regulatory approvals and other customary closing conditions. Bluevine and the Bank have maintained a productive relationship for many years.

As of June 30, 2026, CCBX had 22 active partner relationships across a diversified range of products and services. Given the scale of the CCBX platform and the Bank’s established sweep capability, the Company does not currently expect the Transaction, or any resulting changes to the Bluevine deposit relationship, to have a material adverse effect on the Company’s liquidity or funding profile. The Company will provide additional information in connection with its third quarter earnings.

As of September 25, 2026, approximately $447 million of Bluevine-related deposits were held on the Bank’s balance sheet, an amount that fluctuates in the ordinary course based on customer activity, balance sheet management and utilization of the Bank’s deposit sweep arrangements. This relationship represents one part of a broader and diversified CCBX deposit platform.

The Bank’s funding alternatives, including the ability to bring sweep deposits back onto its balance sheet, provide flexibility to replace Bluevine-related deposits.

All statements, other than statements of historical fact, including statements regarding the anticipated impact of the Transaction, are forward-looking statements.

The Company cannot guarantee that any forward-looking statement will be accurate.

Readers are, therefore, cautioned not to place undue reliance on any forward-looking statement. Any forward-looking statement speaks only as of the date of this Current Report on Form 8-K, and, except as required by law, the Company does not undertake any obligation to update any forward-looking statement to reflect new information, events or circumstances.
