PBHC · Pathfinder Bancorp, Inc.

Pathfinder Bancorp, Inc. and Castle Creek Capital Partners VII, L.P. executed the Fourth Amendment to the Registration Rights Agreement on May 4, 2026, further extending the company's obligation to file a resale registration statement for securities sold in the 2019 private placement. This marks the fourth such extension, following amendments in 2023, 2024, and 2025, each granting an additional year. The updated Filing Deadline is now the eighth anniversary of the May 8, 2019 Closing Date, effectively May 8, 2027, with adjustment for non-business days. For investors, this amendment provides continued flexibility in compliance timing without altering other terms of the original agreement, signaling ongoing dialogue between the parties but potential delays in liquidity for the registered securities.
