Deep Yellow Limited has delayed making a final investment decision on Tumas, its uranium development in Namibia, pushing the milestone past the fourth quarter of 2026 after citing weak equity-market conditions that were limiting financing options for uranium developers.

A final investment decision is the point at which a company formally commits the capital needed to move a project from preparatory work into full-scale construction. Deep Yellow had been working toward making that commitment on Tumas within the fourth quarter of 2026.

The Australian Securities Exchange-listed company said equity markets remained challenging across the uranium sector, constraining the funding avenues available to project developers. It said it considered it prudent to defer the Tumas final investment decision beyond the fourth quarter of this year rather than proceed on the original schedule.

Deep Yellow managing director and chief executive officer Greg Field said "challenging equity market conditions continue to constrain funding options for uranium developers." Field said the company is "progressing our funding strategy to ensure Tumas is well positioned to advance when market conditions improve."

Construction-related work at the Tumas site was continuing despite the deferred decision, the company said. Civil works under way included concrete preparation, installation of reinforcing steel, and off-site pre-casting, and all of this work was being funded from Deep Yellow's existing cash reserves rather than from new capital raised for the project.

Alongside the ongoing construction, Deep Yellow was finalizing an optimization study and an updated value case for Tumas. The company said the two would be released together as part of a comprehensive project update once they were complete. It did not give a revised date for when the final investment decision might now be announced, saying only that the deferral would extend beyond the fourth quarter of 2026.

Despite the delay, Deep Yellow said it retained confidence in Tumas, describing the project as a future "next-generation, secure and reliable supplier of uranium." Field pointed to what he called "compelling global uranium market fundamentals" as grounds for that confidence, even as he acknowledged that near-term conditions for raising project financing remained difficult.

The company had previously been targeting an announcement on the Tumas final investment decision within the fourth quarter of 2026, before confirming this week that the timeline would slip. Deep Yellow did not disclose the amount of capital the project still required or the size of its cash reserves at that time, saying only that the civil works then under way were fully funded without the need for additional financing at that stage.

The company said construction momentum at the site would be maintained while it continued work on its financing arrangements, and that further detail on Tumas's funding strategy and project economics would follow once the optimization study and value case were finalized.
