Amaero (AMRO.US), a supplier of titanium and refractory metal powders for defense and aerospace 3D printing, unveiled its Nasdaq IPO terms on Tuesday. The Tennessee-based company plans to issue 7.5 million shares at an assumed price of $7.06 per share, targeting gross proceeds of $53 million.

The $7.06 figure is derived from the closing price of its Australian Securities Exchange-listed shares (ticker: 3DA) on September 11, converted at prevailing exchange rates. Based on that offering price, Amaero's fully diluted market capitalization would be approximately $221 million. The company will list under the ticker AMRO on Nasdaq, with Stifel and Baird serving as joint book-runners. Pricing is expected on Tuesday, September 22.

Where the company fits

Amaero manufactures spherical powders of refractory metals and titanium alloys for additive manufacturing, alongside large near-net-shape components produced via powder metallurgy hot isostatic pressing (PM-HIP). Its powder portfolio includes niobium, tungsten, tantalum, molybdenum, rhenium, and titanium alloys, engineered for 3D printing of components used in hypersonic weapon systems, satellite propulsion, strategic missiles, aerospace, and medical applications. Founded in 2013, the company reported revenue of $12 million for the twelve months ended June 30, 2026.

This is not a newly formed entity. The business originated in Australia in 2013 as Amaero Engineering Pty Ltd, completed its ASX listing in December 2019 under the 3DA ticker, and was renamed Amaero Ltd in April 2025. A US restructuring followed—Amaero Inc. was incorporated in Delaware on February 20, 2026, with the redomiciliation completed on June 22. The company filed confidentially on July 10 and submitted its formal S-1 registration document on August 28. In short, this Nasdaq offering represents a venue change for a company already publicly traded in Australia for nearly seven years, rather than a first-time capital markets debut.

Rapid growth, persistent losses

Financially, Amaero sits in a classic "high revenue growth, not yet profitable" phase. In fiscal 2026 (ended June 30), revenue reached A$18.1 million, up 376% year over year, with the fourth quarter setting a record A$7.8 million in revenue, up 417%. Contract backlog stood at A$23.1 million, equivalent to 128% of fiscal 2026 revenue.

Two landmark orders stand out. On July 22, the company secured a A$6.5 million (approximately $4.5 million) contract from the US Department of Defense for alternative refractory alloy powder development, spanning 13 months through August 2027 and centered on C103 niobium-hafnium-titanium alloy for hypersonic and space propulsion use. In April, Amaero signed a titanium powder supply agreement with a private equity-backed advanced materials customer worth a minimum of A$7.8 million, running from July 2026 through June 2027—a deal the company says roughly equals its entire fiscal 2026 titanium powder sales. It plans to approximately double titanium powder output in fiscal 2027.

Profitability, however, remains elusive. According to aggregated data from Simply Wall St, the company posted a net loss of A$36.52 million over the trailing twelve months, with a gross margin of -26.12% and a price-to-sales ratio of approximately 13.9 times. Separate figures from HDIN Research indicate 23,833,200 common shares outstanding as of June 30, 2026, with cumulative losses of $75.5 million.

Growth and losses expanding simultaneously is a shared characteristic of materials companies in this capacity-ramp-up stage. Amaero sits at the tightest link in the 3D printing chain: metal additive manufacturing has expanded rapidly in recent years, but the supply of "qualified powders" has not kept pace. High-performance titanium and refractory powders have historically been sourced overseas, leaving US defense and aerospace programs exposed to long lead times and export control pressures.

What sets the technology apart

Amaero's bet centers on filling that gap. Its core platform is Electrode Induction Melting Gas Atomization (EIGA)—a "non-contact" gas atomization process that differs from crucible-contact melting, enabling production of high-purity spherical titanium and refractory alloy powders while avoiding contamination of reactive, high-melting-point metals. According to Pitt Street Research, Amaero's EIGA Premium platform achieves a spherical titanium powder yield of roughly 50%, nearly double the approximate 25% yield of conventional EIGA processes, at a production cost of about half that of plasma atomization or spheroidization routes.

Capacity is a verifiable metric. The company's McDonald, Tennessee facility operates three EIGA atomizers—two for titanium alloys and one for refractory alloys—representing combined capacity of approximately 480 tonnes per year for titanium alloy powder and roughly 200 tonnes per year for refractory alloy powder, totaling about 680 tonnes annually. A third unit was brought online ahead of schedule in August. A three-year, A$72 million capital expenditure program has been completed on time and on budget, and the company has disclosed raising A$32.3 million to accelerate a fourth atomizer targeted for production in June 2027.

Amaero describes itself as the largest domestic US producer of spherical titanium and refractory powders, with a product line spanning grades such as C103 niobium-based powder for rocket engines and hypersonic applications.

The second pillar is PM-HIP: powder is loaded into sealed containers and subjected to high temperature and pressure, yielding large near-net-shape components with properties approaching forged parts. For the US submarine and maritime industrial base, this path can bypass lengthy cast-and-forge queues. The company says it is advancing multiple first-article qualification programs with prime defense contractors—an essential gateway from prototypes to volume production that distinguishes it from "laboratory companies." Amaero holds ISO 9001/AS9100 certifications and maintains ITAR registration.

Why the timing works

Amaero's decision to pursue a US listing now comes amid broad warming across the materials segment. On the demand side, refractory metals are the tightest. Industry publication PowderSight estimates global demand for spherical refractory metal powders in additive manufacturing will reach 21,000 tonnes, growing at 23.6% year over year. A single hypersonic program can require annual demand in the hundreds of kilograms, yet the number of companies with reliable global supply capability is limited.

The publication also notes that the Asia-Pacific region surpassed North America for the first time this year as the world's largest metal 3D printing materials market, with China accounting for 68% of Asia-Pacific volume. Aerospace contributes roughly 35% of global metal 3D printing revenue.

Supply-side dynamics are policy-driven. US domestic sponge titanium capacity has essentially vanished, leaving the country heavily import-dependent, while China accounts for about 70% of global sponge titanium production. The Pentagon's domestic supply chain strategy (DFARS compliance) has designated domestic titanium and refractory powders as critical materials, with "de-risking" efforts continuously intensifying—a strategic direction that directly determines where orders flow.

Peer activity provides supporting evidence. ATI reported fiscal-quarter revenue of $1.26 billion, up 11% year over year, with adjusted EBITDA up 37% to $284 million and backlog at an all-time high of $4.4 billion; premium titanium alloy lead times have extended to 20 months. IperionX secured a second US Army SBIR Phase 3 task order on August 31, with a base amount of $18.5 million (of which $11.5 million has been funded, with options raising the ceiling to $25.4 million), part of an IDIQ contract with a $99 million total cap, targeting titanium powder capacity of approximately 200 tonnes per year by the end of 2026. 6K Additive posted first-half revenue of $13.27 million, up 73%.

Adjacent moves are equally active: Elmet Group signed an agreement to acquire ams OSRAM's tungsten-molybdenum business in Schwabmünchen, Germany, establishing its first EU production base. Plansee extended its Upper East tungsten mine supply agreement with miner Almonty to 21 years. Kennametal launched KAF82, its first commercial additive tungsten carbide grade.

Capital market temperatures can be read even more directly: on September 16, the A-share 3D printing sector index rose more than 2%.
