AML3D (ASX:AL3) is an Adelaide-founded additive-manufacturing company whose proprietary ARCEMY wire-arc metal 3D-printing systems build large metal components layer by layer. Over the past two years it has pivoted hard toward the United States naval shipbuilding Supply chain, and that bet is now the central pillar of its Investment case. For a small-cap industrial that has long promised more than it delivered, FY26 was the year the numbers finally started to move.

The question of whether AML3D can surprise the market is really a question about scale: can a company with a strong order book and a marquee customer base convert that into sustained, profitable revenue?

A record year, but still loss-making

For FY26, AML3D reported Revenue of about AUD 12.5 million, up roughly 70% year on year, with Gross Profit rising 54% to AUD 7.8 million at a 63% gross margin. The net loss after tax narrowed to AUD 4.5 million, a 38% improvement, and while the full year remained EBITDA-negative at around AUD 4.2 million, the second half delivered a small EBITDA profit of about AUD 608,000 — the company’s first profitable half at that level.

Just as important is the pipeline. AML3D exited FY26 with a peak order book of roughly AUD 29 million during the year and about AUD 16.8 million of orders rolled into FY27, up 87% on the prior rollover. It finished the year with about AUD 26.7 million in cash, giving it runway to invest.

The US defence engine

The growth story is overwhelmingly a US one. American customers accounted for the bulk of first-half revenue, and AML3D has stacked up orders tied to the US Navy’s submarine and maritime industrial base. Notable wins during the year included a roughly AUD 2.6 million order in March 2026 for submarine components via BlueForge Alliance, and a AUD 9.9 million follow-on order from shipbuilder Newport News in June 2026 for additional ARCEMY systems, with delivery flagged for early 2027.

The strategy is twofold: sell printed parts, and sell the ARCEMY machines themselves to defence primes and contractors so they can print in-house. Success on the second front turns AML3D from a jobbing manufacturer into an equipment and technology supplier with a broader footprint.

Why it matters to investors

AML3D sits at the intersection of two powerful themes — the AUKUS-driven build-out of allied submarine capability and the wider adoption of additive Manufacturing for defence and heavy industry. A growing, US-weighted order book and an improving Margin trajectory are the tangible evidence that the pivot is gaining traction.

Catalysts to watch include conversion of the FY27 order book into recognised revenue, commissioning of the newly ordered ARCEMY systems, any further US Navy or prime-contractor orders, and whether the second-half EBITDA profit can be sustained across a full year.

Risks to weigh

The risks are considerable. AML3D remains loss-making at the net level and depends heavily on a small number of large US customers, so timing slippage on a single contract can swing results. Revenue in the first half of FY26 actually fell before the second-half recovery, underscoring how lumpy the Business is. The company is also exposed to US defence procurement cycles and currency movements, and continued growth may require further investment.

AML3D has moved from promise toward proof, but the next phase must show that a record order book can become durable, profitable revenue rather than another peak that fades.
