SDI Announces Corporate Update

Wakefield, Massachusetts – July 24, 2018 (TSX-V: SDZ) (OTCQB: SDEV) Security Devices International Inc. (“SDI” or “the Company”) continues the development on their less lethal Personal Security Devices (“PSD”), announces changes to officers of the Company and Board of Directors, and issues securities to officer.

Development of Less Lethal Personal Security Devices

On April 15, 2018, the Company announced its acquisition of patents and related Intellectual Property (“IP”) focused on a new less lethal platform that delivers chemical irritants from a handgun-like Personal Security Device. As its first product offering utilizing the new IP, the Company is planning the introduction of a small, light-weight, .68 caliber hand-held PSD equipped with a 7-round magazine and capable of accurately and effectively engaging a target at up to 60 feet – less lethally and without causing serious injury. Targeted at home owners and enthusiasts who want protection without the burdens of gun ownership, the Company has already secured a commitment for 1,000 PSD’s from one of the leading distributors of firearms and accessories on the African continent.

Change to the Board of Directors

The Company is delighted to announce the addition of Paul Jensen to the SDI Board of Directors. Mr. Jensen, a graduate of the United States Military Academy at West Point, will bring his global network of contacts along with extensive product development experience to the Board as the Company expands outside of North America and continues to bring innovative security products to market.

Paul Jensen has been appointed Chief Executive Officer of the Company from his current position as President & COO and will continue to steer our product development and move the Company into new markets that require less lethal platforms and munitions. Bryan Ganz has been appointed President of the Company from his current position of Executive Chairman and will be responsible for capital markets, investor relations, and some of our larger partners.
