Exhibit 99.1

TASER Q1 Revenues Increase 19 Percent to $30.4 Million

Video Segment Revenues Increase 32 Percent Sequentially

SCOTTSDALE, Ariz., April 25, 2013 — TASER International, Inc. (NASDAQ: TASR), today announced financial results for the first quarter of 2013 ended March 31, 2013.

Financial Summary:

“The Smart Weapon platform that we have built over the last two years with the X2 and X26P provides compelling new capabilities for our customers to upgrade their aging weapons,” remarked Rick Smith, CEO of TASER International, Inc. “Sales of the newly released X26P Smart Weapon were very strong in the first quarter, accounting for more than 10% of our CEW sales, and we expect that trend to continue in the future as agencies recognize the benefits of our new Smart Platform. X2 CEW sales reflected continued growth in the first quarter. We also saw growth in the number of agencies embracing on-officer recording systems through sales of AXON Flex™ on-officer cameras and EVIDENCE.com service. We continue to receive positive feedback from the marketplace about the value-add of these products and are excited about the future as we look to expand our customer base in the Video segment.

“We believe that digital video and multi-media will become the centerpiece of law enforcement records in the future and TASER is well positioned to deliver an end-to-end solution that enables new capabilities that leverage a cloud-based model to allow for rapid, easy implementation for our customers. In both of our segments, we will continue to invest in the sales force as we look to grow the top-line, as well as the infrastructure necessary to deliver operational excellence to all of our customers, ultimately executing our strategy to drive profitable growth and value for our stakeholders while generating significant operating cash flows.” concluded Smith.

A reconciliation of GAAP to the non-GAAP financial measures is presented at the end of the release.
