ISBC 2017 Form 10-K & 2018 Proxy Statement

3 How do I vote shares held in Investors Bancorp benefit plans? If you are a participant in our Employee Stock Ownership Plan or 401(k) Plan, or any other benefit plans sponsored by us through which you own shares of our common stock, you will have received a Notice Regarding the Availability of Proxy Materials. Under the terms of these plans, the trustee or administrator votes all shares held by the plan, but each participant may direct the trustee or administrator how to vote the shares of our common stock allocated to his or her plan account. If you own shares through any of these plans and you do not vote by May 17, 2018, the respective plan trustees or administrators will vote your shares in accordance with the terms of the respective plans. Can I change my vote after submitting my proxy? You may revoke your proxy at any time before the vote is taken at the Annual Meeting. You may revoke your proxy by: • submitting written notice of revocation to the Corporate Secretary of Investors Bancorp prior to the voting of such proxy; • submitting a properly executed proxy bearing a later date; • voting again by telephone or Internet (provided such vote is received on a timely basis); or • voting in person at the Annual Meeting; however, simply attending the Annual Meeting without voting will not revoke an earlier proxy. Written notices of revocation and other communications regarding the revocation of your proxy should be addressed to: Investors Bancorp, Inc. 101 JFK Parkway Short Hills, New Jersey 07078 Attention: Brian F. Doran, Esq., Corporate Secretary If your shares are held in street name, you should follow your broker’s instructions regarding the revocation of proxies. Who pays the expenses of this proxy solicitation? Investors Bancorp will bear the entire cost of soliciting proxies. In addition to solicitation of proxies by mail, Investors Bancorp will request that banks, brokers and other holders of record send proxies and proxy material to the beneficial owners of Investors Bancorp common stock and secure their voting instructions, if necessary. Investors Bancorp will reimburse such holders of record for their reasonable expenses in taking those actions. Laurel Hill Advisory Group, LLC will assist us in soliciting proxies and we have agreed to pay them a fee of $7,500 plus reasonable expenses for their services. Innisfree M&A Incorporated, which has been providing assistance in connection with stockholder advisory services, will also assist in soliciting proxies and we have agreed to pay them a fee of $20,000. If necessary, Investors Bancorp may also use several of its regular employees, who will not be specially compensated, to solicit proxies from stockholders, personally or by telephone, facsimile or letter. In the event there are not sufficient votes for a quorum, or to approve or ratify any matter being presented at the time of this Annual Meeting, the Annual Meeting may be adjourned in order to permit the further solicitation of proxies.
