Cornerstone Bank, a subsidiary of PeoplesBancorp, and Athol Savings Bank announced the execution of a merger agreement, pursuant to which Athol Savings Bank (ASB) will merge with and into Cornerstone Bank, which will expand Cornerstone into a new and vibrant region in north central Massachusetts. As part of the merger, ASB will operate as a division of Cornerstone Bank, maintaining its name and five branch locations. This strategic move allows Cornerstone Bank to bring its full suite of digital banking services and customer-focused innovations to an expanded clientele, while preserving the trusted local brand that ASB has built.

“This is an incredibly exciting time for us,” said Todd Tallman, CEO of Cornerstone Bank. “We are growing. Athol Savings Bank has a great team, and its mission, values and commitment to mutuality align seamlessly with ours. This move will strengthen our ability to serve our communities while preserving our focus on customer service. Our combined scale will make us more efficient, expand product offerings and improve customer service through shared resources and technology. In today’s industry, scale matters.”

ASB’s strong financial performance and customer-first approach align well with Cornerstone’s commitment to growth and innovation. Customers can expect the same seamless, local service with even better technology and improved access to financial planning tools on a robust digital platform, elevating their overall banking experience. Further, as a combined organization, it will allow for enhanced commitment to charitable giving, community involvement and volunteerism in the North Quabbin region.

ASB staff will be retained and fully supported throughout the transition, with significant focus made to ensure continuity in roles by offering the same or similar positions. This collaboration is rooted in growth, not reduction.

In a key leadership transition, Daniel J. Zona, the current President and Chief Executive Officer of ASB, will assume the role of President of Cornerstone Bank, succeeding Randal Webber, who announced in March he will be retiring. The Cornerstone Bank Board of Directors will also expand to welcome four new members, including Zona, helping to round out leadership representation across the newly expanded region the bank will now serve.

“I’m honored to lead Cornerstone Bank into this next chapter,” said Zona. “Both banks share a commitment to our community, employees and customers. Together, we can achieve strategic growth while maintaining a community-first approach rooted in mutual values.”

Completion of the transaction remains subject to approval by the corporators of ASB, as well as regulatory approval. The closing is expected to be final in the first quarter of 2026.
