6K Additive completes AUS$48M IPO to boost powder capacity
6K Additive, a division of 6K, based in North Andover, Massachusetts, USA, has announced the successful completion of its IPO on the Australian Stock Exchange (ASX), raising AUS$48 million at an offer price of AUS$1.00 per CDI. It will trade as 6KA.
At the Offer Price, 6K Additive has an initial market capitalisation of approximately AUS$267 million and an enterprise value of approximately AUS$206 million. The IPO was said to have attracted strong support from a range of new institutional, family office and sophisticated investors in Australia and overseas, together with existing shareholders.
“The IPO and resulting capital fast-track the realisation of our vision and achieve the scale with attractive unit economics and unique material breadth required by customers in defence, aerospace, energy, and medical markets,” said Frank Roberts, CEO and Managing Director of 6K Additive. “As a strategic supplier to the US 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.”

Expansion plan
The combination of IPO proceeds and a US$23.4 million grant from the US Department of Defense’s Defense Production Act Title III is expected to enable 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 said to already be underway at 6K’s 45-acre global headquarters in Burgettstown. Plans include expanding the existing powder-production operations with space for up to ten additional UniMelt machines, 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$27.4 million Export-Import Bank low-cost long-term loan facility (EXIM Loan). The EXIM Loan builds upon the DPA Title III Grant of US$23.4 million to finance the construction of four new buildings and the acquisition of advanced equipment to produce titanium, nickel powders and alloy additions.
Sales pipeline to grow to US$240 million
6K Additive also announced that its sales pipeline has expanded to US$240 million as of end of November 2025, marking a US$10 million increase over the past two months. As the company expects demand to continue to grow, 6K Additive will continue to focus on scaling production and optimising operating metrics to deliver greater value to its customers and partners.
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 organisation has in the coming three to five years.”
