Another US milestone, another share price drop: What’s going on with this ASX stock?

Metallium Ltd (ASX: MTM) shares are under pressure on Tuesday, even as the company chalks up another milestone in its US expansion strategy.

In midday trade, the Metallium share price is down 2.42% to 60.5 cents.

That leaves the stock down roughly 42% since the start of 2026, despite still sitting well above where it traded a year ago after a huge 12-month run.

The weaker move suggests investors may be weighing valuation and execution after a string of strong US announcements over recent months.

Let’s take a closer look.

US defence work moves into the next phase

Today’s update confirmed Metallium has successfully completed Phase I of its Small Business Innovation Research (SBIR) contract. The project was run in partnership with the US Department of War’s Defence Logistics Agency (DLA).

The program focused on recovering gallium from semiconductor and electronic waste streams using the company’s Flash Joule Heating technology.

Management said all technical milestones were achieved or exceeded, with the work completed in 6 months, around half the usual SBIR Phase I timeline.

Gallium is used in radar systems, semiconductors, satellite electronics, and advanced communications. The United States currently relies almost entirely on imports for this supply.

Metallium said its process could help recover gallium from alternative waste feedstocks, supporting domestic supply chain security and reducing dependence on overseas production.

The company also noted the successful completion may support a potential Phase II SBIR funding round worth up to US$1 million. This is expected to help fund further development and pilot-scale deployment.

Why the shares may still be under pressure

Despite the positive milestone, today’s weakness may reflect a market that was already expecting further progress in the company’s US strategy.

Metallium has been highly active in Texas, where it is scaling its Gator Point Technology Campus and targeting 8,000 tonnes per annum of PCB feedstock throughput by the end of 2026.

With a market capitalisation of about $449 million, the stock has already delivered a one-year return of about 388%, even after the 2026 pullback.

At this stage, investors may be waiting for the next major update to come from commercial revenues, additional US government funding, or further progress at the Texas facility.

What to watch next

The next key item to watch is whether Metallium can convert this successful defence contract into Phase II funding.

Longer term, investors will also be watching for commercial gallium recovery lines to emerge at its Texas campus.

If that happens, today’s pullback could look more like a pause after such a strong run.
