Rhinebeck Bancorp, Inc.

Under the supervision and with the participation of our management, including our Principal Executive Officer and Principal Financial Officer, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the fiscal year (the “Evaluation Date”). Based upon that evaluation, the Principal Executive Officer and Principal Financial Officer concluded that, as of the Evaluation Date, our disclosure controls and procedures were effective.

Our management is responsible for establishing and maintaining effective internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Under the supervision and with the participation of our management, including our Principal Executive Officer and Principal Financial Officer, we evaluated the effectiveness of our internal control over financial reporting based on criteria established in “Internal Control — Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment, management, including our Principal Executive Officer and Principal Financial Officer, concluded that our internal control over financial reporting was effective and met the criteria of the “Internal Control — Integrated Framework (2013)” as of December 31, 2025.

Not applicable because the Company is a non-accelerated filer.

There were no changes in our internal control over financial reporting that occurred during the fourth quarter of fiscal 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
