Current Stock Performance

As of 17 September 2025, Silex shares traded at A$4.82, placing the company’s market capitalisation at approximately A$1.11–1.17 billion. Over the past year, the stock has seen a wide trading range, touching a low of A$2.28 and a high of A$6.62. Liquidity has been supported by average daily turnover of over 1 million shares, with peaks coinciding with major announcements or policy developments in nuclear and quantum sectors.

Financial Metrics

For the trailing twelve months, Silex reported revenue of A$13.68 million, derived from licence and milestone payments, alongside early silicon isotope shipments and collaboration income. The company recorded a net loss of A$42.56 million, reflecting significant research and development expenditure, joint venture contributions, and scale-up costs. Earnings per share were negative at −A$0.18. Conventional valuation measures such as the price-to-earnings ratio remain non-meaningful given the development-stage profile, while the price-to-book ratio stands at around 11–12x.

Outlook and Considerations

Silex’s near-term performance is closely linked to regulatory progress for GLE under the US Nuclear Regulatory Commission, milestones in silicon isotope demonstration, and funding pathways for scale-up activities. The absence of a dividend reflects the company’s focus on reinvestment into R&D and joint ventures.
