Non-GAAP Reconciliation This presentation contains financial information and performance measures determined by methods other than in accordance with generally accepted accounting principles in the United States (“GAAP”). Sandy Spring Bancorp’s management believes that the supplemental non-GAAP information provides a better comparison of period-to-period operating performance. Additionally, Sandy Spring Bancorp believes this information is utilized by regulators and market analysts to evaluate a company’s financial condition and, therefore, such information is useful to investors. Non-GAAP measures used in this presentation consist of the following: • efficiency ratio • tangible common equity • core earnings Efficiency Ratio. Management views the GAAP efficiency ratio as an important financial measure of expense performance and cost management. The ratio expresses the level of non-interest expenses as a percentage of total revenue (net interest income plus total non-interest income). Lower ratios indicate improved productivity. In general, the efficiency ratio is non-interest expenses as a percentage of net interest income plus non-interest income. Noninterest expenses used in the calculation of the non-GAAP efficiency ratio excludes intangible asset amortization and non-recurring or extraordinary items. Non-interest income is adjusted to exclude securities gains and losses and nonrecurring or extraordinary items, and net interest income is adjusted to include tax-equivalent income. The measure is different from the GAAP efficiency ratio, which also is presented in this document. The GAAP measure is calculated using non-interest expense and income amounts as shown on the face of the Consolidated Statements of Income. The GAAP and non-GAAP efficiency ratios are reconciled and provided in the following table. Tangible Common Equity. Tangible equity, tangible assets and tangible book value per share are non-GAAP financial measures calculated using GAAP amounts. Tangible common equity and tangible assets exclude the balances of goodwill and other intangible assets from stockholder’s equity and total assets, respectively. Management believes that this non-GAAP financial measure provides information to investors that may be useful in understanding our financial condition. Because not all companies use the same calculation of tangible equity and tangible assets, this presentation may not be comparable to other similarly titled measures calculated by other companies. Core Earnings. Core earnings is a non-GAAP financial measure calculated using GAAP amounts. Core earnings reflect net income for the period exclusive of merger, acquisition and disposal expense, amortization of intangible assets, and other nonrecurring or extraordinary items, in each case net of tax. Management believes that this non-GAAP financial measure provides helpful information to investors in understanding the Company’s core operating earnings and provides a better comparison of period-to-period operating performance of the Company. 24
