 to a distribution pursuant to the registration statement of which this prospectus forms a part. The selling stockholders may also sell shares under Rule 144 or any other exemption from registration under the Securities Act, if available, rather than under this prospectus supplement. Broker-dealers engaged by the selling stockholders may arrange for other broker-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling stockholders (or, if any broker- dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated, but, except as set forth in a prospectus supplement, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2121. Any broker-dealers or agents that are involved in selling the shares may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each of the selling stockholders has informed the Company that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the shares. We have agreed with the selling stockholders to keep the registration statement of which this prospectus supplement constitutes a part effective until the earliest to occur of (i) the date on which all of the shares of our common stock covered by this prospectus supplement have been sold, (ii) such time as each selling stockholder is eligible to sell all of such shares of our common stock under Rule 144 of the Securities Act without any limitation as to volume or manner of sale or (iii) the six-monthanniversary of the issuance of such shares to the selling stockholders, subject to certain exceptions. We have agreed to indemnify the selling stockholders against S-16

certain liabilities in connection with the offering of the shares and will pay certain expenses of the registration of the shares offered hereby, including the SEC filing fees.

If any selling stockholder notifies us that it has a material arrangement with a broker-dealer for the resale of the shares, then we would be
required to amend the registration statement of which this prospectus supplement is a part, and file a prospectus supplement to describe the agreement between such selling stockholder and the broker-dealer.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale
