This Amendment No. 1 (“Amendment No. 1”) to Schedule 13D relates to the common stock, par value $0.01 per share (the “Common Stock”), of Enterprise Bancorp, Inc., a Massachusetts corporation (the “Issuer”), and amends and supplements the initial statement on Schedule 13D filed on December 8, 2023 (the “Schedule 13D”). Except as specifically amended by this Amendment No. 1, the Schedule 13D remains in full force and effect. The principal executive offices of the Issuer are located at 222 Merrimack Street, Lowell, MA 01852.

The shares of Common Stock were sold through a trade order executed by a broker-dealer at a price of $25.25 per share of Common Stock. As a result of these sales, the Trust now owns 720,802 shares of Common Stock. The Trust sold the shares of Common Stock to pay for certain taxes associated with estate of Mr. Ansin’s father. In the future, Mr. Ansin may determine to sell additional shares of Common Stock for tax, estate or other economic planning purposes. Otherwise, Mr. Ansin has no plans to engage in any of the kinds of transactions enumerated in Item 4(a)-(j).
