6K Additive Awarded US$1.95M by U.S. Defense Agency to Advance U.S. Strategic Metals Independence

Burgettstown, PA, March 5th, 2026 – 6K Additive (ASX: 6KA) is pleased to announce that it has been awarded a new Phase II contract with a total value of US$1.95 million over an 18-month term and is subject to standard U.S. government contract terms, including performance milestones and termination rights ( Award ). The Award aims to lessen the U.S. military's dependence on foreign sources for critical strategic metals. The initiative focuses on converting domestic scrap including Nickel, Titanium, Tungsten, and Niobium—into high-value metal powders for additive manufacturing and defense readiness. The goal of the award is to maximize the value of end-of-life components, high demand and high value metal alloys leveraging the baseline processes developed in previous 6K Additive U.S. Defense awards.

Background

The U.S. defense industrial base currently faces a strategic vulnerability due to its heavy reliance on imported metals. According to Statista China controls over 80% of global Tungsten production, and the U.S. depends entirely on imports for Niobium, primarily from Brazil and Canada. Titanium imports have also been flagged by the Department of Commerce as a threat to national security.

"The U.S. Government has made it clear that to advance our defense readiness we cannot rely on geopolitically sensitive regions for the materials essential to our most advanced weapon systems," said Frank Roberts, CEO of 6K Additive. "By upcycling domestic scrap we are creating a circular, secure, and sustainable supply chain for the US defense sector."

At the heart of this initiative is 6K Additive’s three IP technology pillars:

• the company’s strategic process for sizing solid scrap into angular powder;

• the use of our UniMelt platform; and

• in-house post-processing capabilities that combined enable transformation of scrap, such as machine turnings and end-of-life parts, into premium spherical powders.

Project Timeline and Impact

The Award has an 18-month timeline, and the program aims to prove the concept of an automated sorting prototype and the deliver certified batches of tungsten, titanium, and niobium powders. By converting domestic waste into high-performance feedstock, 6K Additive is ensuring that American innovation is powered by American materials.

6K Additive’s strategic importance to the United States national defense regime is validated by strong and growing government support, including:

• US$23.4 million Defense Production Act Title III grant

• US$12.4 million in Defense Logistics Agency programs over recent years, including the conversion of titanium and nickel into high-value powder and, in 2025, a US$1.8 million program for the processing of niobium and titanium scrap – all from the U.S. military depots

• US$27.4 million Export-Import Bank approved loan facility

As previously advised to the market, this support reflects the recognition of 6K Additive as a critical supplier to U.S. national security and industrial resilience.

Approved by 6K Additive Board of Directors

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.
