Results of Review of Interim Financial Information

We have reviewed the accompanying interim consolidated financial information of The First Bancorp, Inc. and Subsidiary as of June 30, 2026 and 2025 and for the three-month and six-month periods then ended, and the related notes (collectively referred to as the "interim financial information"). Based on our reviews, we are not aware of any material modifications that should be made to the accompanying interim financial information for them to be in conformity with accounting principles generally accepted in the United States of America.

Basis for Review Results

This consolidated interim financial information is the responsibility of the Company's management. We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.
