PYROGENESIS SIGNS AGREEMENT WITH U.S. DEFENSE CONTRACTOR TO JOINTLY PURSUE CHEMICAL WEAPON DESTRUCTION CONTRACTS IN SYRIA

PyroGenesis Inc. has signed an agreement with the national security and defence division of a U.S. multinational engineering infrastructure corporation to jointly pursue contracts for the safe destruction of chemical weapons in Syria. The partner's name is being withheld for competitive and confidentiality reasons at the request of the client.

Project highlights

Purpose:  the safe destruction of the remaining chemical weapons in Syria that were produced and stored by the previous regime

Scope:  design, engineering, and supply of PyroGenesis's PACWADS (plasma arc chemical warfare agent destruction system), including all auxiliary systems, set-up, engineering/training support, and after-sales service and support

Timeline:  responding to tendered projects during 2026

Strategic impact:  supports the global need to safely eliminate weapons of mass destruction, especially chemical weapons such as those listed under the United Nations' Chemical Weapons Convention by the Organization for the Prohibition of Chemical Weapons (OPCW)

As outlined in the outlook section of PyroGenesis's Q2 2025 earnings report (see press release dated Aug. 6, 2025), PyroGenesis was in negotiations with a multinational defence contractor for the potential sale of a PyroGenesis PACWADS for destroying chemical weapons (CWs). The agreement announced today is a progression of that initial discussion, with the two companies teaming to jointly pursue contracts that are expected to be tendered during 2026, for CW destruction specific to stockpiles located in and around Syria.

Under this agreement, and if these pursuits are successful, PyroGenesis would provide its PACWADS technology, associated auxiliary systems, and various engineering, training, operational and after-sales services to various locations where required in conjunction with its defence partner, the Syrian government, and organizations related to the prohibition and remediation of chemical weapons. The exact number and scale of the PACWAD units required is to be determined during the coming tendering process.

PyroGenesis's tactical PACWADS is a safe, versatile, efficient and mobile destruction system, which uses high-temperature electric plasma to eliminate a variety of dangerous biological warfare agents and chemicals, including sarin, mustard gas, soman, VX and others. The tactical PACWADS system was originally funded and developed with the Defense Advanced Research Projects Agency (DARPA), the central research and development organization of the U.S. Department of Defense. With a 99.9999-per-cent (or 6N) destruction efficiency, the PACWADS leaves only a non-toxic salt effluent that can be safely disposed of. These systems are typically designed for use in the field or near conflict zones, and they serve several key purposes, including protecting human lives, environmental preservation, compliance with international treaties, operational efficiency and mobility.

"We are honoured to be invited to partner on this important initiative," said P. Peter Pascali, president and chief executive officer of PyroGenesis. "Chemical weapons pose one of the gravest threats to global security, and, if our joint bids are successful, PyroGenesis's PACWAD technology will play a vital role in ensuring these weapons of mass destruction never fall into the hands of terrorists or others with malicious intent."

Industry and market context

Since the First World War, where chemical weapons caused nearly 100,000 deaths, more than one million subsequent global casualties instigated the creation of various global initiatives to prohibit chemical weapon use and eliminate stockpiles.

During the Syrian Civil War, the government of President Bashar al-Assad used chemical weapons more than 300 times against its own citizens, leading to thousands of casualties.

According to the United Nations, more than 100 locations in Syria may have been involved in chemical-weapons-related activities in the country. The United States, the OPCW and other governments have long assessed that Syria had not previously declared all its chemical weapons stocks and facilities to the OPCW and more may be still undiscovered.

Since the overthrow of the al-Assad regime, the current Syrian administration has committed to destroying any remaining stockpiles produced during Mr. al-Assad's reign.

Plasma-based chemical weapons destruction offers a cleaner, safer, more scalable alternative to traditional destruction methods that utilize incineration or neutralization.
