Explanatory Note

This Amendment No. 1 on Form 10-K/A (Amendment No. 1) amends the Annual Report on Form 10-K of TASER International,
Inc. (the Company) for the year ended December 31, 2011, originally filed with the Securities Exchange Commission (the SEC) on March 13, 2012.

The Company is filing Amendment No. 1 to replace Exhibit 32  Certification Pursuant to 18. U.S.C. Section 1350 As Adopted
Pursuant to Section 906 of the Sarbanes-Oxley Act of 2002 (Exhibit 32). In the original filing there was a typographical error within Exhibit 32 which indicated the Chief Executive Officer and the Chief Financial Officer were
certifying the Annual Report on Form 10-K of the Company for the year ending December 31, 2010. The intent of Exhibit 32 was to certify the Annual Report on Form 10-K of the Company for the year ending December 31, 2011, not
December 31, 2010. As such, the Company is filing this Amendment No. 1 solely to correct the dates in Exhibit 32 and Amendment No. 1 does not amend any other information set forth in the original filing, and the Company has not
updated disclosures included therein to reflect any events that occurred subsequent to December 31, 2011.
