6K ADDITIVE | GROUP OVERVIEW

MARKET OPPORTUNITIES / TAILWINDS

ADDITIVE MANUFACTURING (AM)

Forecasted to expand at a 25% 5-year CAGR, outpacing the broader metal powder market; 6KA derives most of its revenue from AM, with growing penetration into PM.

==> picture [44 x 44] intentionally omitted <==

STRUCTURAL SHIFT

Metal AM is undergoing a structural shift from prototyping to serial production, which now account for 68% of the metal AM equipment market (2024)[1] . Aerospace and defense are the primary catalysts, driving demand for complex, high-temperature components manufactured from nickel, titanium and refractory alloys.

==> picture [47 x 47] intentionally omitted <==

==> picture [51 x 51] intentionally omitted <==

==> picture [80 x 63] intentionally omitted <==

THE US SUPPRESSOR MARKET

Estimated at ~US$400-500M (2024), has seen demand accelerate sharply following the January 2026 elimination of the US$200 NFA tax stamp. The ATF processed ~150,000 eForms on January 1, ~60x the typical daily volume and leading manufacturers project 2026 sales could double YoY[4] . Suppressors are an ideal AM application due to complex internal geometries, and AM penetration is expected to rise from ~4% (2023) to ~30% by 2030[4] .

METAL POWDER MARKET GROWTH ($B)

Reported by Smartech (2024)

==> picture [42 x 42] intentionally omitted <==

AEROSPACE AND DEFENCE AM

The market is forecast to grow 18% in 2026 to US$6B, reaching US$11.5B by 2030 (17% CAGR)[2] . The U.S. DoD's 2026 budget allocates US$3.3B to AM projects - up 83% YoY - the single largest annual increase, signaling a long-term structural commitment[3] . Across the broader defense industrial base, demand for hightemperature refractory alloys continues to accelerate, driven by next-generation missile systems, propulsion, armor, and hypersonics.

Industry leading premium powder portfolio of 20+ alloys including refractories, titanium, and nickel

OPERATIONAL HIGHLIGHTS

FINANCIAL HIGHLIGHTS

• Customer base expanded significantly in 2025, with 20% of revenue derived from new customers (accelerating to 32% in 4Q25).

• Sustained demand for 6KA’s powder is primarily driven by customers using it in production parts, creating a consumable revenue profile.

• 6KA is experiencing strong customer demand driven by the underlying demand from the suppressor market across both nickel and titanium powders.

• The DLA program with 6KA demonstrated upcycling of government sourced C103 niobium and titanium scrap into premium powders for defense applications, bolstering supply chains and future market demand.

• Powder revenue was flat YoY with fundraising delays as the key reason. Revenue accelerated into 2H25 with HoH growth of 37% highlighting accelerating sales and production momentum, which continued to improve again into 4Q25.

• Revenue growth was very strong for nickel driven by the successful commissioning of the atomizer . Refractories and titanium were also strong.

• Gross margin loss reduced in 2025 with accelerating improvement into 2H25 dropping 80% HoH.
