Forward-Looking Statements This presentation may contain forward-looking statements within the meaning of the securities laws that are based on various facts and derived utilizing important assumptions, present expectations, estimates and projections about Sandy Spring Bancorp, Inc. and its subsidiaries (“Sandy Spring”, “SASR” or “the Company”), and Revere Bank. Statements preceded by, followed by or that otherwise include the words “believes,” “expects,” “continues,” “anticipates,” “intends,” “projects,” “estimates,” “potential,” “plans” and similar expressions or future or conditional verbs such as “will,” “should,” “would,” “may” and “could” are generally forward-looking in nature and not historical facts, although not all forward-looking statements include the foregoing words. Forward-looking statements include information concerning Sandy Spring’s and Revere Bank’s future financial performance, business and growth strategy, projected plans and objectives, as well as projections of macroeconomic and industry trends, which are inherently unreliable due to the multiple factors that impact economic trends, and any such variations may be material. Such forward-looking statements are not guarantees of future performance and are subject to risks and uncertainties, many of which are outside of Sandy Spring’s and Revere Bank’s control, which may cause actual results to differ materially from those expressed or implied by the forward-looking statements. These risks and uncertainties include but are not limited to whether Sandy Spring can: continue to develop and maintain new and existing customer and community relationships; successfully implement its growth strategy, including identifying suitable acquisition targets and integrating the businesses of acquired companies and banks, including in connection with its pending acquisition of Revere Bank; sustain its current internal growth rate; provide quality and competitive products and services that appeal to its customers; continue to have access to debt and equity capital markets; and achieve its performance objectives. These and various other risk factors are discussed in Sandy Spring’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018 and in other reports and statements Sandy Spring has filed with the Securities and Exchange Commission (“SEC”). Copies of such filings are available for download free of charge from the Investor Relations section of Sandy Spring’s website at www.sandyspringbank.com. In addition to the above factors and those previously disclosed in Sandy Spring’s reports filed with the SEC, the following factors among others, could cause actual results to differ materially from those in its forward-looking statements: (i) the possibility that any of the anticipated benefits of the proposed transaction between Sandy Spring and Revere Bank will not be realized or will not be realized within the expected time period; (ii) the risk that integration of operations of Revere Bank with those of Sandy Spring will be materially delayed or will be more costly or difficult than expected; (iii) the inability to complete the proposed transaction due to the failure to obtain the required shareholder approvals; (iv) the failure to satisfy other conditions to completion of the proposed transaction, including receipt of required regulatory and other approvals; (v) the failure of the proposed transaction to close for any other reason; (vi) the effect of the announcement of the transaction on customer relationships and operating results; (vii) the possibility that the transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events; (viii) general economic conditions and trends, either nationally or locally; (ix) conditions in the securities markets; (x) changes in interest rates; (xi) changes in deposit flows, and in the demand for deposit, loan, and investment products and other financial services; (xii) changes in real estate values; (xiii) changes in the quality or composition of Sandy Spring’s or Revere Bank’s loan or investment portfolios; (xiv) changes in competitive pressures among financial institutions or from non-financial institutions; (xv) the ability to retain key members of management; and (xvi) changes in legislation, regulations, and policies. Any forward-looking statement made by Sandy Spring in this presentation speaks only as of the date on which it is made. Factors or events that could cause Sandy Spring’s actual results to differ may emerge from time to time, and it is not possible for Sandy Spring to predict all of them. Sandy Spring undertakes no obligation to publicly update any forward-looking statement, whether as a result of new information, future developments or otherwise, except as may be required by law. Preliminary Results As of and For the Three Months Ended September 30, 2019 This presentation contains SASR’s preliminary results as of and for the three months ended September 30, 2019. SASR has not filed its Quarterly Report on Form 10-Q for the quarter ended September 30, 2019. As a result, all financial results as of and for the three months ended September 30, 2019 described herein should be considered preliminary and are subject to change to reflect any changes resulting from the completion of normal quarter-end closing and review procedures. SASR’s actual results may differ materially from these estimates due to the completion of financial closing procedures, final adjustments and other developments that may arise between the date of this presentation and the time SASR files its Quarter Report on Form 10-Q. Forward Looking Statements and Non-GAAP Financial Information

Non-GAAP Financial Measures This presentation includes certain non-GAAP financial measures. In accordance with the SEC’s rules, Sandy Spring classifies a financial measure as being a non-GAAP financial measure if that financial measure excludes or includes amounts, or is subject to adjustments that have the effect of excluding or including amounts, that are included or excluded, as the case may be, in the most directly comparable measure calculated and presented in accordance with generally accepted accounting principles as in effect from time to time in the United States in our statements of income, balance sheet or statements of cash flows. Non-GAAP financial measures do not include operating and other statistical measures or ratios or statistical measures calculated using exclusively either financial measures calculated in accordance with GAAP, operating measures or other measures that are not non-GAAP financial measures or both. The non-GAAP financial measures discussed herein should not be considered in isolation or as a substitute for the most directly comparable or other financial measures calculated in accordance with GAAP. Moreover, the manner in which Sandy Spring calculates the non-GAAP financial measures may differ from that of other companies reporting measures with similar names. You should understand how such other banking organizations calculate their financial measures similar or with names similar to the non-GAAP financial measures when comparing such non-GAAP financial measures. Sandy Spring believes these non-GAAP financial measures provide useful information to management and investors that is supplementary to our financial condition, results of operations and cash flows computed in accordance with GAAP; however, such non-GAAP financial measures have a number of limitations. As such, you should not view these disclosures as a substitute for results determined in accordance with GAAP, and they are not necessarily comparable to non-GAAP financial measures that other companies use. Please refer to the reconciliation of these non-GAAP financial measures to their most comparable GAAP measure in the appendix to this presentation.

Appendix

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; and tangible common equity. 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. Non-interest expenses used in the calculation of the non-GAAP efficiency ratio exclude merger expenses, goodwill impairment losses, litigation expenses, the amortization of intangibles, and other non-recurring expenses. Income for the non-GAAP ratio includes the favorable effect of tax-exempt income, and excludes securities gains and losses, which vary widely from period to period without appreciably affecting operating expenses, and non-recurring gains. 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.
