Use of Non-GAAP Financial Measures This presentation includes certain financial information that is calculated and presented on the basis of methodologies that are not in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”). These non-GAAP financial measures include pre-tax pre-provision return on average assets, pre-tax pre- provision return on average equity, tangible book value, tangible common equity, tangible assets and efficiency ratio. The non-GAAP financial measures included in this presentation do not replace the presentation of FVCB’s GAAP financial results, should not be considered as a substitute for operating results determined in accordance with GAAP and may not be comparable to other similarly titled measures of other companies. These measurements provide supplemental information to assist management, as well as certain investors, in analyzing FVCB’s core business, capital position and results of operations. FVCB has chosen to provide this additional information to investors because it believes that these measures are meaningful in assisting investors to evaluate FVCB’s core ongoing operations, results and financial condition.
