Alpha HPA (ASX:A4N), a specialty materials and technology company, said it has started low volume supply to the pharmaceutical sector, according to a Wednesday Australian bourse filing.

The company continues production at the stage 1 HPA First project across its full range of high-purity alumina materials and is building stage 2 of the project, the filing said.

The company is also in talks with Japanese end-users regarding further thermal filler supply contracts this fiscal year, the filing added.

Meanwhile, expected and existing demand for fiscal 2026 and 2027 are higher than the existing capacity, and the company said it is reviewing a number of ways to manage capacity allocation and increase capacity.

Development of its nano alumina slurry product is also close to completion, and the company expects to start high volume manufacturing of the alumina dispersion in March, per the filing.

Shares of the company fell nearly 1% in recent Wednesday trade.
