(“PyroGenesis” or the “Company”) (TSX: PYR) (OTCQX: PYRGF) (FRA: 8PY1), a leader in ultra-high temperature processes and engineering innovation, and a plasma-based technology provider to heavy industry &amp; defense, today announces its first contract toward a new titanium powder supply agreement with a U.S.-based materials distributor (the “Client”). The powder for this order has been produced by PyroGenesis’ NexGen™ plasma atomization process and is to be shipped this week. The Client’s identity and contract details will remain confidential for competitive reasons. As disclosed in the Outlook section of the Company’s Q2 2026 earnings release, dated August 6, 2026, the Company has been in discussion with several companies regarding titanium powder orders, including a US-based materials distributor for a monthly supply agreement of up to 500 kg. Today’s contract represents the first commercial order arising from those discussions. The Client has since indicated that its potential monthly requirements could reach 1,000 kg (1 tonne); however, no commitment for recurring orders at that volume has been made. The order is for Ti64 “fine” cut powder, with a particle size range of 20-80µm (microns). This powder is typically used in laser powder bed fusion (LPBF), an additive manufacturing technology widely used to produce complex, high-density components for aerospace, healthcare, and automotive industries. The Client supplies U.S. customers in the aerospace, defense, energy, and broader advanced manufacturing sectors. “The contract announced today directly supports the strategic goals outlined in our April 29, 2026, press release: positioning the Additive Manufacturing Division for its next level of growth, with operations anticipated to be several times larger than those currently in place,” said Mr. P. Peter Pascali, President and CEO of PyroGenesis. “This relationship with a well-connected materials distributor serving both the aerospace and defense sectors will help us expand our customer base in these two key industries that we have identified as central to achieving those strategic goals.” PyroGenesis’ Technology Development for Additive Manufacturing PyroGenesis is the inventor of the plasma atomization process and in fact coined the term “plasma atomization” in its original patent. Plasma atomization is often considered the gold standard process for the production of metal powder for additive manufacturing, also referred to as metal 3D printing. After years of R&amp;D, PyroGenesis redesigned its plasma atomization technology and launched NexGen™ to re-enter the powder production market by targeting higher quality and yields, at lower operating costs. The Company has since taken a deliberate approach to commercialization, progressing from gram-scale customer samples to 100-kg orders, and its first tonne-scale order in May 2023. PyroGenesis produces titanium powders in particle size distribution ranges across three “cuts”: <ul type="disc"><li>Fine Cut, in particle sizes between 15–63 µm for use in laser powder bed fusion (LPBF).</li><li>Coarse Cut, in particle sizes between 45–106 µm for use in electron beam melting (EBM) and 45–150 µm in directed energy deposition (DED).</li><li>Off-Cuts, in particle sizes not currently used by the existing range of commercial printers, but which offers a high-quality feedstock for use in the production of high-quality metal alloys.</li></ul> <img alt="PyroGenesis’ titanium metal powder as produced by its NexGen™ plasma atomization system." height="361" name="GNW_RichHtml_IMG" src="https://ml.globenewswire.com/Resource/Download/5b8b5bea-6909-44b7-ac08-2664cd5c55ab/2228.jpg" width="600" data-dpi="96" data-caption="PyroGenesis’ titanium metal powder as produced by its NexGen™ plasma atomization system." data-filename="2228.jpg" /> Image: PyroGenesis’ titanium metal powder as produced by its NexGen™ plasma atomization system. INDUSTRY AND MARKET CONTEXT <ul type="disc"><li>The global 3D printing market specific to titanium powder is expected to increase from $214 million in 2023 to $1.4 billion by 2032.1</li><li>Titanium is classified as a critical mineral by both Canada2 and the U.S.3</li><li>Titanium is used by multiple industries, including space, aerospace, defense, consumer electronics, medical, hydrogen, and electric vehicles, due to its high strength-to-weight ratio and corrosion resistance.</li></ul> About PyroGenesis Inc.
