BURGETTSTOWN, Pa., Dec. 4, 2025 /PRNewswire/ -- 6K Additive, a global leader in advanced metal powders and alloy additions, today announced the successful completion of its IPO on the Australian Stock Exchange (ASX), raising A$48m at an offer price of A$1.00 per CDI (Offer Price). At the Offer Price, 6K Additive has an initial market capitalization of approximately A$267m and an enterprise value of approximately A$206m. The Company's CDIs will trade on ASX under the ticker symbol 6KA. The IPO attracted strong support from a range of new institutional, family office and sophisticated investors in Australia and overseas, together with existing shareholders. Trusted by leading organizations across aerospace, defense, space, medical, energy, and automotive sectors, 6K Additive plans to use the newly secured capital to support its expansion plan to better serve its growing customer base and broaden its product offerings.

Expansion plan

The combination of IPO proceeds and a US$23.4m grant from the US Department of War's Defense Production Act Title III enables 6K Additive to scale its metal-powder production capacity to over five times its current output, from ~200 metric tons to 1,000 metric tons, and initiate commercial ingot production capability. Construction is already underway at the Company's 45-acre global headquarters in Burgettstown, PA. Plans include expanding the existing powder-production operations with space for up to ten additional UniMelt® systems, adding new structures for feedstock preparation, melting operations for ingots, and building a dedicated refractory production facility.

Newly Secured EXIM Loan

The IPO comes on the heels of 6K Additive's recent media release of the approval of a US$27.4m Export-Import Bank low-cost long-term loan facility (EXIM Loan). The EXIM Loan builds upon the DPA Title III Grant of US$23.4m to finance the construction of four new buildings and the acquisition of advanced equipment to produce titanium, nickel powders and alloy additions.

With the combination of IPO proceeds, the DPA Title III Grant, and the new EXIM Loan, 6K Additive is well-capitalised to:

• Complete its near-term capacity expansion program at its global headquarters campus in Burgettstown, PA on schedule;
• Invest in additional UniMelt® plasma systems and downstream processing equipment to significantly scale titanium and high-performance nickel alloy powder production; and
• Pursue strategic growth opportunities with key clients in the aerospace, defence, energy, and industrial sectors.

Sales Pipeline Grows to US$240m

6K Additive's sales pipeline has expanded to US$240m as at end of November 2025, marking a US$10m increase over the past two months. This growth highlights the strong demand for 6K Additive's premium metal powders. As demand is expected to continue to grow, 6K Additive remains committed to scaling production and optimizing operating metrics to deliver exceptional value to its customers and partners.

"The IPO and resulting capital fast-track the realization of our vision and achieve the scale with attractive unit economics and unique material breadth required by customers in defense, aerospace, energy, and medical markets," said Frank Roberts, CEO and Managing Director of 6K Additive. "As a strategic supplier to the U.S. Department of War and its Tier-1 contractors, our products, production processes and technology have been qualified in their supply chains, reinforcing these relationships. This growth enables a domestic supply of critical materials for applications such as hypersonics, nuclear fusion, medical implants, and rocket-engine development."

David Seldin, 6K Additive Chairman of the Board and Managing Partner of Anzu Partners commented, "As an institutional investor in 6K Additive from its inception, I witnessed this organisation grow to the leading domestic provider of metal powders and alloy additions. The breadth and quality of 6K Additive's products, the trusted relationship with the US Department of War and the dedicated employee talent, underscores the potential this organization has in the coming 3-5 years."

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.
