Rhea-AI Filing Summary

DEFSEC Technologies Inc. announced that its U.S. contract manufacturer received an ATF determination that the single-shot ARWEN Micro (Pro-1) is not a “Destructive Device” under U.S. federal firearms law; it remains an “Any Other Weapon” (AOW). An ATF open letter dated October 9, 2026 indicated the agency would not enforce AOW tax-stamp requirements or require federal approval or registration for AOW manufacture or purchase. The federal process is similar to that for a pistol or handgun, while state and local laws continue to apply. The launcher fires .67-cal pepper-powder projectiles and has a stated 60-ft effective range.

Design and functional evaluation is largely complete, and DEFSEC completed initial low-rate production in Canada for markets outside the United States. Most tooling for full-scale ammunition production is complete at its U.S. contract manufacturer. DEFSEC is planning U.S. launcher production and preparing its market introduction, including any regulatory permits and authorizations for production, sale and distribution, and selection of U.S.-based component sources. It expects to begin civilian sales as early as Q2 of calendar 2027.

How this balance works

Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.

It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.

Rhea-AI Sentiment measures something else, the tone of the wording.

4 terms

Destructive Device regulatory

"not a “Destructive Device” under U.S. federal firearms law"

A legal classification for weapons and devices that are designed, modified, or intended to cause widespread damage, injury, or destruction; the exact items covered vary by jurisdiction but commonly include explosive or incendiary devices (bombs, grenades), certain rocket or missile systems, chemical or biological agents, and large-caliber firearms or barrels above a statutory size. Which specific objects and size or capability thresholds qualify as a destructive device is set by statute or regulation in each jurisdiction, and that designation triggers special criminal prohibitions and licensing, registration, transfer, and storage rules separate from ordinary firearms laws.

Any Other Weapon regulatory

"remains classified as an “Any Other Weapon”"

Low Energy Cartridge technical

"Company’s patented “Low Energy Cartridge” technology"

low-rate initial production technical

"completed initial low-rate initial production"

Low-rate initial production is a controlled, small-scale manufacturing run used to build a limited number of units to validate production processes, supply chains, and product performance before committing to full-scale output. For investors, it signals that a product has moved beyond development toward commercialization but will generate only modest near-term revenue while reducing technical and manufacturing risk—think of it as a rehearsal before opening the factory doors wide.

DEFSEC Receives Favorable ATF Classification for Arwen Micro Non-Lethal Irritant Launcher, Clearing Path to U.S. Civilian Market

OTTAWA, ON, Nov. 3, 2026 /CNW/ -- DEFSEC Technologies Inc. (TSXV: DFSC) (TSXV: DFSC.WT.U) (NASDAQ: DFSC) (NASDAQ: DFSCW) ("DEFSEC" or the "Company") announces that its U.S. contract manufacturer has received a determination from the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives ("ATF") that the single-shot ARWEN Micro ("Pro-1") is not a "Destructive Device" under U.S. federal firearms law. The Pro-1 is based on the Company's patented "Low Energy Cartridge" ("LEC") technology, and remains classified as an "Any Other Weapon" ("AOW").

The ATF determination removes a significant barrier to selling U.S.-manufactured Pro-1 units to civilian buyers. "Destructive devices" are subject to substantial regulatory and cost burdens. Further, as of October 9, 2026, an open letter from the ATF¹ indicated that it will not enforce the tax stamp requirements associated with AOWs and will not require federal approval or registration for the manufacturing or purchase of AOWs. This results in a federal process that is similar to that of a pistol or handgun. State and local laws continue to apply. Pro-1

• A compact single-shot non-lethal device firing .67-cal pepper-powder projectiles that burst on impact; built-in light and laser sight; 60-ft effective range.
• Cartridge-based, not air-powered: no CO², compressed air, or gunpowder for high cartridge reliability with no gas to leak, no seals or O-rings to fail, no cold-weather pressure loss -- always ready to fire reliably and consistently.
• Inert rounds will also be sold for practice enabling users to become familiar and proficient with the product.

These present a significant advantage over third-party legacy products in the market.

"This ATF determination opens the U.S. civilian personal-safety market. With almost 83 million gun owners in the United States², this is a significant opportunity for DEFSEC. With tooling already in place and the product proven through initial production in Canada, we are well positioned to move quickly to U.S. production and launch." said Sean Homuth, President and Chief Executive Officer of DEFSEC. "The Pro-1 was developed to be a non-lethal alternative for personal protection (and public safety) enabling safe conclusions to incidents without the use of lethal force"

Production and market readiness

Design and functional evaluation of the Pro-1 is largely complete. DEFSEC has completed initial low-rate initial production at its Canadian manufacturing operations in preparation for markets outside the United States. The majority of tooling for full-scale production of Pro-1 ammunition is complete at DEFSEC's U.S. contract manufacturer for the U.S. market.

The Company is now planning U.S. production of the launcher and is preparing its U.S. market introduction plan, including any regulatory permits and authorisations for the production, sale and distribution of the products, and the selection of U.S.-based sources of supply for various components. DEFSEC expects to begin selling the Pro-1 to the U.S. civilian market as early as Q2 of calendar 2027.

Such forward-looking statements are based on the current expectations of DEFSEC's management and are based on assumptions and subject to risks and uncertainties that are documented in detail in the Company's public filings. 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 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™ 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 success of U.S. production of the launcher and the Company's U.S. market introduction plan, acquisition of the required regulatory permits and authorizations, 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 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 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.

Except as required by applicable securities laws, forward-looking statements speak only as of the date on which they are made and DEFSEC undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.
