BAR HARBOR BANKSHARES

Except as set forth below, there were no material changes to the risk factors discussed in Part I, Item 1A. “Risk Factors” of our Form 10-K.

The Company may fail to realize the anticipated benefits of its previously announced merger with Guaranty Bancorp, Inc.

The Company and Guaranty entered into an Agreement and Plan of Merger, dated as of March 11, 2025 (the “Merger Agreement”), pursuant to which Guaranty will merge with and into the Company (the “Merger”). The Company and Guaranty have operated independently and will continue to do so until the completion of the Merger. The success of the Merger, including anticipated benefits and cost savings, will depend on, among other things, the Company’s ability to successfully combine the businesses of the Company and Guaranty, including by minimizing any disruptions to the existing customer relationships and business functions of the Company or Guaranty, and avoiding any inconsistencies in standards, controls, procedures and policies. If the Company is not able successfully to achieve these objectives, the anticipated benefits of the Merger may not be realized fully, or at all, or may take longer to realize than expected. Failure to achieve these anticipated benefits could result in increased costs, decreases in the amount of expected revenues and diversion of management’s time and energy and could have an adverse effect on the Company’s business, financial condition, operating results and prospects.

The Company will incur integration costs in connection with the Merger.

The Company will incur integration costs following the completion of the Merger, including facilities and systems consolidation costs and employment-related costs. There can be no assurances that the expected benefits and efficiencies related to the integration of the businesses will be realized to offset these transaction and integration costs over time. The Company may also incur additional costs to maintain employee morale and to retain key employees.
