Item 2.02 Results of Operations and Financial Condition

On February 28, 2014 the jury in the commercial litigation case of AA & Saba Consultants, Inc. v. TASER International, Inc. returned a verdict of $3,300,000 against the Company. Judgment has not yet been entered and the judgment is subject to an award of attorneys’ fees. The Company believes the verdict is not supported by the evidence and intends to appeal.

The Company had previously reserved $750,000 related to this case based on a previous settlement offer to plaintiff; as such, in accordance with generally accepted accounting principles, the Company will record additional expense of $2,550,000 in the fourth quarter of 2013 resulting in a net impact, after income taxes, on the Company’s previously reported fourth quarter 2013 financial results, of approximately $1,548,000, or $0.03 per share on a basic and diluted basis. Should the plaintiff be awarded reimbursement of legal fees, additional expense will be recorded by the Company.
