Avidia Bancorp, Inc. (the “Company”) (NYSE: “AVBC”), the holding company of Avidia Bank, today reported third quarter financial results.

Concurrent with the mutual-to-stock conversion of Avidia Bank’s former mutual holding company and as described in the prospectus for the Company’s initial public offering (“IPO”), the Company made a $10 million, one-time donation, of 900 thousand shares of common stock at a total market value of $9.0 million and a $1.0 million cash contribution to the Avidia Bank Charitable Foundation, Inc. This contribution resulted in a net loss of $907 thousand for the third quarter of 2025, or ($0.05) per share, compared to net income of $3.9 million reported for the prior quarter.

“We are pleased with the results for our initial quarter as a publicly traded company” said Robert Cozzone, President and Chief Executive Officer. “Our core metrics are solid, and we are well positioned for the future.”
