Dear Fellow Sandy Spring Bancorp Shareholder: The annual meeting of shareholders of Sandy Spring Bancorp, Inc. will be held on May 24, 2023, and we need your support. In addition to electing directors and approving our auditors, shareholders are being asked to modernize our corporate governance through updates to our Articles of Incorporation, as described in the enclosed materials. The changes we are proposing are intended to give shareholders greater ability to influence governance policies and hold management accountable by providing for the annual election of all directors and by making it easier for shareholders to approve future changes to our Articles of Incorporation. Your participation is critically important – and it takes just a few minutes to return the enclosed proxy card or to vote electronically or by phone using the instructions on the card. If we do not receive your proxy, you may receive a phone call from a representative of our proxy solicitor, Georgeson, reminding you to exercise your right to vote. We are proud of our 155 years of supporting our clients and communities and we ask that you support us by voting. Thank you for your interest and investment in Sandy Spring Bancorp, Inc. Sincerely, 
Daniel J. Schrider Chair, President and Chief Executive Officer |
