SUPPLEMENT TO PROXY STATEMENT

FOR THE ANNUAL MEETING OF STOCKHOLDERS

To be Held on May 24, 2018

This proxy statement supplement, dated May 17, 2018 (the “Supplement”), supplements the definitive proxy statement (which we refer to as the “Proxy Statement”) of the Board of Directors of Axon Enterprise, Inc. (the “Company”) filed with the U.S. Securities and Exchange Commission on April 13, 2018 relating to the annual meeting of stockholders of the Company to be held at 10:00 a.m. (local time) on Thursday, May 24, 2018, at the Company's headquarters located at 17800 North 85th Street, Scottsdale, AZ 85255. The purpose of this Supplement is to revise information with respect to the number of meetings of the board of directors during 2017 and director attendance at such meetings. Except as described in this Supplement, the information disclosed in the Proxy Statement continues to apply. To the extent that information in this supplement differs from information disclosed in the proxy statement, the information in this Supplement applies.

The Company determined during a review of its corporate records that a telephonic call involving members of the board of directors to update them about certain Company matters was inadvertently classified as a meeting of the board of directors. This update call was not an officially noticed or convened meeting of the board of directors. The Company is filing this Supplement to revise the section in the Proxy Statement titled “Meetings of the Board of Directors” as reflected below.

As Originally Disclosed:

Meetings of the Board of Directors

During the year ended December 31, 2017, the Board held five meetings. During 2017, each director, with the exception of Bret Taylor, attended at least 75% of all regular Board and applicable committee meetings.

As Revised:

Meetings of the Board of Directors

During the year ended December 31, 2017, the Board held five four meetings. During 2017, each director, with the exception of Bret Taylor, attended at least 75% of all regular Board and applicable committee meetings.

Meetings of the Board of Directors

During the year ended December 31, 2017, the Board held four meetings. During 2017, each director attended at least 75% of all regular Board and applicable committee meetings.

The Proxy Statement, together with this Supplement, have been filed with the Securities and Exchange Commission and are also available for viewing at the website maintained for the annual meeting at www.proxyvote.com (as well as on the Company’s website at www.investor.axon.com). The Company will furnish a copy of the Supplement to any stockholder by mail upon written or verbal request to the Company at Axon Enterprise, Inc., 17800 North 85th Street, Scottsdale, AZ 85255, Attn: Investor Relations, or at ir@axon.com.
