DISCLOSURES Forward-Looking Statements Except for historical information, the matters discussed may include “forward-looking statements.” Those statements are subject to material risks and uncertainties. 1st Source cautions readers not to place undue reliance on any forward-looking statements, which speak only as of the date made. The audience is advised that various important factors could cause 1st Source’s actual results or circumstances for future periods to differ materially from those anticipated or projected in such forward-looking statements. Please refer to our press releases, Form 10-Qs, and 10-Ks concerning factors that could cause actual results to differ materially from any forward-looking statements of which we undertake no obligation to publicly update or revise. Non-GAAP Financial Measures The accounting and reporting policies of 1st Source conform to generally accepted accounting principles (“GAAP”) in the United States and prevailing practices in the banking industry. However, certain non-GAAP performance measures are used by management to evaluate and measure the Company’s performance. Although these non-GAAP financial measures are frequently used by investors to evaluate a financial institution, they have limitations as analytical tools, and should not be considered in isolation, or as a substitute for analyses of results as reported under GAAP. These include taxable-equivalent net interest income (including its individual components), net interest margin (including its individual components), the efficiency ratio, tangible common equity-to-tangible assets ratio, pre-tax pre-provision income and tangible book value per common share. Management believes that these measures provide users of the Company’s financial information a more meaningful view of the performance of the interest-earning assets and interest- bearing liabilities and of the Company’s operating efficiency. Other financial holding companies may define or calculate these measures differently. See the slides titled “Reconciliation of Non-GAAP Financial Measures” for a reconciliation of certain non-GAAP financial measures used by the Company with their most closely related GAAP measures. 2page
