Sandy Spring Bancorp’s forward-looking statements may also be subject to other risks and uncertainties, including those that it may discuss elsewhere in this presentation or in its filings with the SEC, accessible on the SEC’s Web site at www.sec.gov. All forward-looking statements attributable to Sandy Spring Bancorp are expressly qualified in their entirety by these cautionary statements. Forward-looking statements speak only as of the date on which such statements are made. Except as required by law, Sandy Spring Bancorp disclaims any obligation to update these forward-looking statements, whether as a result of new information, future events or otherwise. There is no assurance that future results, levels of activity, performance or goals will be achieved. 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.

The negative impact to market value, due to a 100 basis point upward shock, was reduced by 23% following the repositioning. • The investment portfolio strategy for 2022 is to continue to reinvest maturing cash flows in short term securities with limited average life extension. • The interest bearing deposit beta in the up 100bp scenario is 35%. • At December 31, 2021, floating rate loans represented 24% of total loans and 52% of floating loans were at their floor. 31 Source: Company documents 31

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 Subtitle used in this presentation consist of the following: Copy • efficiency ratio • pre-provision net revenue • tangible common equity • core return on average assets 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 excludes intangible asset amortization, loss on FHLB redemption, and merger and acquisition expense from non-interest expense, securities gains from non-interest income and adds the tax- equivalent adjustment to net interest 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. Pre-Provision Net Revenue. Pre-provision net revenue is a non-GAAP financial measure calculated using GAAP amounts, equal to net interest income plus non-interest income less non- interest expense. 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 pre-provision net revenue, this presentation may not be comparable to other similarly titled measures calculated by other companies. 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 Return on Average Assets. Core return on average assets is a non-GAAP financial measure calculated using GAAP amounts. Core earnings reflect net income for the period exclusive of the provision for credit losses, provision for unfunded commitments, merger and acquisition expense, amortization of intangible assets, loss on FHLB redemption, and investment securities gain, 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. 43 43
