"George (bio below) is a respected veteran of the defence and security industry, with extensive international experience in the public safety market from many years leading the Canadian and International Red Cross and Red Crescent.

Forward-looking statements included in this include, but are not limited to: management's belief of sufficiency of available financial resources to support forecasted activities in 2026 based on cash on hand, anticipated revenue streams and planned expenditures in the fiscal year, subject to execution of the Company's operating plan and other risks and factors described in its public filings; interest in DEFSEC Lightning™ 2.0 or other products and services as well as timing of full implementation, subscription uptake or commercial release thereof; the Company's estimates of program billings on an annualized go-forward basis and increases to annualized gross margin on a go-forward basis and extent thereof, if any; the outcome and timing of test and evaluation activities for BLISS™ at the United States Army Yuma Test Center and whether such activities result in follow-on orders; the ability to sustain full-rate production of, and demand for, ARWEN® 40mm baton ammunition; the stage of scaled production for the PARA SHOT™ technology into new training cartridges and timing of release thereof; the intended use of net proceeds from the June 2026 registered direct offering and concurrent private placement and whether any warrants are exercised; and management's belief that its extensive customer base of law enforcement agencies for ARWEN® throughout North America is a ready market for its new products like PARA SHOT™ as well as DEFSEC Lightning™.

Although DEFSEC's management believes that the assumptions underlying such forward-looking statements are reasonable, they may prove to be incorrect. The forward-looking statements discussed in this news release may not occur by certain specified dates or at all and could differ materially as a result of known and unknown risk factors and uncertainties affecting DEFSEC, including DEFSEC's inability to execute on its current operating plan and/or fiscal 2026 forecasted activities, DEFSEC's inability to secure contracts and subcontracts (on the timelines, size and scale expected or at all), statements of work and orders for its products in fiscal 2026 and onwards for reasons beyond its control, the renewal or extension of agreements beyond their original term, the granting of patents applied for by DEFSEC, inability to finance the scale up to full commercial production levels for its physical products, inability to secure key partnership agreements to facilitate the outsourcing and logistics for its ARWEN® and PARA SHOT™ products, inability to commercialize DEFSEC's Battlespace Laser Identification Sensor System (BLISS™), inability to secure or complete the execution of government contracts, inability to drive growth in DEFSEC's ARWEN® product line, inability to advance the commercialization of DEFSEC's PARA SHOT™ products, delay or inability to grow subscriptions for DEFSEC's Lightning™ 2.0 SaaS offering, lower than expected or delayed demand for DEFSEC's BLISS™, overall interest in DEFSEC's products being lower than anticipated or expected; general economic and stock market conditions; a stagnation or decrease in North American defence and public safety spending, adverse industry events; future legislative and regulatory developments in Canada, the United States and elsewhere, including changes to the continued listing requirements of the Nasdaq Capital Market and the TSX Venture Exchange; the inability of DEFSEC to implement and execute its business strategies; the Company's ability to raise additional capital when required and on acceptable terms; risks and uncertainties detailed from time to time in DEFSEC's filings with the Canadian Security Administrators and the United States Securities and Exchange Commission, and many other factors beyond the control of DEFSEC.
