PROXY STATEMENT

General Information

This proxy statement is furnished to you and other stockholders of AmTrust Financial Services, Inc. (“AmTrust,” “the Company,” “our,” “us,” or “we”) in connection with the solicitation of proxies by our Board of Directors to be used at a Special Meeting of Stockholders to be held at our headquarters at 59 Maiden Lane, 43rd Floor, New York, New York 10038, on Tuesday, December 15, 2015, at 10:00 a.m. (Eastern time) and any adjournment or postponement thereof. All stockholders are entitled to attend the Special Meeting in person. This proxy statement, the form of proxy and voting instructions are being made available to stockholders on or about November 12, 2015.

All shares of common stock represented by properly executed proxies received pursuant to this solicitation will be voted in accordance with the stockholder’s directions specified on the proxy. If no directions have been specified by marking the appropriate squares on the accompanying proxy card, the shares will be voted “FOR” approval of the amendment to our Amended and Restated Certificate of Incorporation. In connection with any other business that may properly come before the Special Meeting, all properly executed proxies delivered pursuant to this solicitation and not revoked will be voted in the discretion of persons appointed as proxies. Stockholders wishing to revoke a proxy prior to its exercise may do so by giving written notice of revocation to our Corporate Secretary, by submitting a proxy with a later date, or by attending the Special Meeting, revoking the proxy and voting in person. If you are a beneficial owner, you must have a legal proxy from your bank, broker or nominee in order to vote in person at the Special Meeting.

We will pay all expenses in connection with this solicitation of proxies. We will reimburse custodians, nominees or other persons for their out-of-pocket expenses in sending proxy materials to beneficial owners and seeking instructions related thereto. Our directors, officers and certain other individuals authorized by us may personally solicit proxies and will not be receiving any special compensation for taking such actions.

Voting

The Board has fixed the close of business on October 30, 2015 as the record date for determining the holders of common stock entitled to notice of and to vote at the Special Meeting. Each such stockholder is entitled to one vote per share. As of the record date, there were 82,914,099 shares of common stock outstanding.

In voting by proxy with regard to the approval of the amendment to our Amended and Restated Certificate of Incorporation, stockholders may vote FOR or AGAINST the proposal, or may abstain from voting.

A majority of the outstanding common stock, represented in person or by proxy, constitutes a quorum for the transaction of business at the Special Meeting. In accordance with the applicable provisions of Delaware law, approval of Proposal 1 requires the affirmative vote of a majority of the outstanding shares of our common stock entitled to vote.

Abstentions will be treated as shares that are present and entitled to vote for the purpose of determining the presence of a quorum, but as unvoted for the purpose of determining the approval of any matter submitted to the stockholders for a vote. Since approval of the proposed amendment to our Amended and Restated Certificate of Incorporation requires a majority of the outstanding shares of our common stock entitled to vote, an abstention will have the same effect as a vote AGAINST the amendment.

PROPOSAL 1: APPROVAL OF AN AMENDMENT TO OUR AMENDED AND RESTATED

CERTIFICATE OF INCORPORATION TO INCREASE THE NUMBER OF AUTHORIZED

SHARES OF COMMON STOCK FROM 150,000,000 SHARES TO 500,000,000 SHARES

The Board of Directors has recommended and is seeking stockholder approval of an amendment to our Amended and Restated Certificate of Incorporation to increase the number of our authorized shares of common stock from 150,000,000 to 500,000,000 shares to provide the Company the flexibility to effectuate a stock split and for other future business needs. The text of the proposed amendment to our Amended and Restated Certificate of Incorporation reflecting the increase in our authorized capital is set forth below:

Section 4.1 Classes of Stock. The total number of shares of all classes of stock that the Corporation shall have authority to issue is 510,000,000 shares of capital stock, consisting of 500,000,000 shares of common stock, $0.01 par value per share (the “Common Stock”) and 10,000,000 shares of preferred stock, $0.01 par value per share (the “Preferred Stock”).

If approved by stockholders, the amendment to our Amended and Restated Certificate of Incorporation will become effective upon its filing with the Secretary of State of the State of Delaware, which is anticipated to occur promptly after the meeting.

Reasons for and Effect of the Increase to Authorized Common Stock

As of September 30, 2015, 98,227,312 shares of our common stock, $0.01 par value, were issued, of which 82,908,030 shares were outstanding and 15,319,282 shares were held as treasury shares. Additionally, approximately 7,333,000 shares were reserved for issuance pursuant to our 2010 Omnibus Incentive Plan, 237,000 shares were reserved for issuance upon conversion of our 5.50% Convertible Senior Notes due 2021 and 2,830,000 shares were reserved for issuance upon conversion of our 2.75% Convertible Senior Notes due 2044. These shares reserved for issuance may be issued from treasury shares or from unissued shares.

Assuming the increase in the number of authorized shares of common stock was effective as of September 30, 2015, the same number of shares would be outstanding, held by the Company as treasury shares, reserved for issuance pursuant to our 2010 Omnibus Incentive Plan, reserved for issuance upon conversion of our 5.50% Convertible Senior Notes due 2021 and reserved for issuance upon conversion of our 2.75% Convertible Senior Notes due 2044, and approximately 406,692,000 shares would be unissued and unreserved, and authorized and available for issuance.

The Board of Directors is recommending the amendment to our Amended and Restated Certificate of Incorporation to increase the number of our authorized shares of common stock, primarily because the Board presently intends to declare a two-for-one stock split in the form of a stock dividend payable to stockholders, subject to approval of this Proposal 1 by the stockholders. If the amendment is approved by stockholders, the stock split would become effective at a time to be designated by the Board. The Board’s decision as to whether and when to effect the stock split will be based on a number of factors, including market conditions and existing and expected trading prices for our common stock. Even if stockholders approve the amendment, subject to market conditions, the Company reserves the right to adjust or abandon the stock split if the Board does not deem it to be in the best interests of the Company and its stockholders to effect the stock split at a rate of two-for-one, or at all.

In addition to enabling the stock split, our Board believes that it is in the best interest of the Company and our stockholders to increase the number of authorized shares of our common stock in order to maintain sufficient authorized but unissued and unreserved shares available for issuance to meet valid business needs as they arise. Such business needs may include stock dividends or splits, equity or debt financings, acquisitions, adopting new or modifying current employee benefit plans and other proper corporate purposes identified by our Board in the future. If the proposed amendment is approved, the additional shares will be available for issuance from time to

time by the Company, in the discretion of our Board, without further authorization or vote of our stockholders unless such authorization is required by Delaware law or the rules of NASDAQ or any other securities exchange on which shares of our common stock are then listed. We may seek a further increase in authorized shares from time to time in the future as considered appropriate by our Board of Directors.

The additional common stock to be authorized will become part of the existing class of common stock. This proposal will not affect the rights of the holders of currently outstanding common stock, except for effects incidental to increasing the number of shares of common stock outstanding, such as dilution of the earnings per share and voting rights of current holders of common stock. The additional shares of our common stock for which authorization is sought will have the same par value, voting rights, rights to dividends and distributions and will be identical in all other respects to the shares of our common stock currently authorized. Our stockholders do not have preemptive rights with respect to our common stock. Should the board of directors elect to issue additional shares of common stock, existing stockholders would not have any preferential rights to purchase such shares.

Anti-Takeover Effects of the Proposed Amendment

The proposed increase in the number of authorized shares of common stock could be deemed to have an anti-takeover effect by discouraging an attempt by a third party to acquire control of AmTrust because we could issue the additional authorized shares of common stock in an effort to dilute the common share ownership of the person seeking to obtain control or increase the voting power of persons who would support the Board of Directors in opposing the takeover attempt. However, the proposal to increase the authorized number of shares of common stock is not in response to any current effort of which we are aware to obtain control of AmTrust, and given the current common stock ownership of AmTrust, such an effort would likely be unsuccessful even if we did not increase our authorized shares of common stock.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE “FOR” PROPOSAL 1.
