6K Additive Breaks Ground on Major Facility Expansion in Burgettstown, Powered by DPA Title III Grant and Recent IPO Capital

BURGETTSTOWN, Pa., April 7, 2026 /PRNewswire/ -- 6K Additive, Inc. (ASX: 6KA) a leader in the domestic production of high-performance metal powders, reached a major milestone on March 30th with the official groundbreaking of its 45-acre global headquarters and manufacturing campus expansion. The project is fueled by a $23.4 million Defense Production Act (DPA) Title III grant and the successful completion of the company's Initial Public Offering (IPO) on the Australian Securities Exchange (ASX: 6KA) last December, which raised A$48 million (US$31.4 million).

This milestone is of strategic importance and marks a transformative leap for 6K Additive, enabling a five-fold increase in production capacity, scaling from 200 metric tons to a targeted 1,000 metric tons annually. The project also introduces new commercial capabilities, including tripling the footprint of its existing powder production building for nickel, titanium and stainless-steel metals, adding dedicated facilities for refractory metals and ingot melting, solidifying a 100% domestic supply chain for materials critical to U.S. national security.

"The combination of federal support through the DPA Title III grant and the capital from our successful IPO allows us to fast-track our vision of a secure, sustainable, and domestic supply of critical metals," said Frank Roberts, CEO of 6K Additive. "We aren't just adding floor space and buildings; we're constructing a world-class industrial campus to anchor a secure supply chain across the defense, aerospace, and energy industries."

Securing the Domestic Supply Chain

The expansion directly addresses the critical need for high-performance materials in extreme environments. By leveraging its proprietary metal powder and alloy compacts production capabilities, 6K Additive will produce spherical powders and alloy additions essential for:

• Hypersonics & Defense: High-temperature materials like tungsten, rhenium, and C-103 for missile systems and flight surfaces.
• Nuclear & Energy: Specialized alloys for advanced reactors and fusion energy.
• Aerospace: High-strength nickel and titanium components for next-generation propulsion.

Strategic Funding and Regional Impact

The DPA Title III grant, awarded through the Department of Defense's Manufacturing Capability Expansion and Investment Prioritization (MCEIP) office, covers 50% of the expansion costs. When paired with the IPO proceeds, 6K Additive is fully capitalized to complete the renovation, acquire advanced equipment, and hire over 17 new skilled employees in engineering and technical operations and support the local economic base with 37 constructions jobs.

The project involves the construction of four new buildings, including an alloy warehouse, a dedicated melt building for ingot production, and a pre and post processing production facility funded through the grant and IPO funds with a dedicated state-of-the-art refractory facility being constructed in 2027. Initial production at the expanded Burgettstown site is expected by the end of 2026.

Restriction on purchases of CDIs by US persons

6K Additive is incorporated in the US State of Delaware and its CDIs have not been registered under the US Securities Act of 1933 or the laws of any state or other jurisdiction in the United States. Trading of the CDIs on the ASX is not subject to the registration requirements of the US Securities Act in reliance on Regulation S under the US Securities Act and a related 'no action' letter issued by the US Securities and Exchange Commission to the ASX in 2000. As a result, the CDIs are "restricted securities" (as defined in Rule 144 under the US Securities Act) and may not be sold or otherwise transferred except in transactions exempt from, or not subject to, the registration requirements of the US Securities Act. For instance, US persons may purchase CDIs if they are "qualified institutional buyers" ("QIBs", as defined in and in reliance on the exemption from registration provided by Rule 144A under the US Securities Act). To enforce the transfer restrictions, the CDIs bear a FOR Financial Product designation on the ASX. This designation restricts any CDIs from being sold on ASX to US persons excluding QIBs. In addition, hedging transactions with regard to the CDIs may only be conducted in compliance with the US Securities Act.
