Deep Yellow stock plunged 11% to EUR 0.93, erasing weekly gains, but nuclear fuel demand from AI data centers and 20+ nations' pledges supports long-term outlook. Management holds off on final investment decision for Tumas project.

The rollercoaster week for Deep Yellow came to a bruising end on Friday, with the stock plunging 11 percent to EUR 0.93. The sharp reversal wiped out the gains from what had been a promising stretch just a day earlier, when the shares had been trading at EUR 1.05. That high-water mark now looks distant — the stock sits more than 40 percent below its 52-week peak of EUR 1.64.

The rout caught many investors off guard, coming on the heels of renewed optimism around the nuclear fuel cycle. Yet the underlying thesis for the sector remains as compelling as ever. More than 20 nations have pledged to triple their nuclear power capacity by 2050, positioning uranium as a cornerstone of low-carbon baseload electricity. The explosive energy demands of artificial intelligence data centres are also pushing utilities to lock in long-term supply agreements, while Western buyers steadily shift away from Russian-origin material. Chronic underinvestment in new mines over the past decade has only tightened the supply picture.

Deep Yellow sits squarely in the middle of this narrative, with two major projects in Namibia and Australia that give it significant leverage to rising uranium prices. The flagship Tumas project in Namibia has reached 68 percent completion on its technical design and 91 percent on earthworks. Yet management is holding back on a final investment decision, arguing the current uranium price does not yet guarantee sufficient economics. The market's patience is wearing thin — the stock now trades roughly 10 percent below its 50-day moving average, and investors are looking for catalysts such as offtake agreements or a binding green light on construction.

Should investors sell immediately? Or is it worth buying Deep Yellow?

Further out, the Mulga Rock project in Western Australia is undergoing a feasibility study that will examine not only uranium but also rare earths and other critical minerals. The company aims to boost the mine's scalability. Deep Yellow has ample financial runway to support these efforts: as of late March 2026, it held AUD 171.6 million in liquid assets. The next major milestone comes in the third quarter of 2026, when the Mulga Rock feasibility study results are due.

Until then, the stock remains hostage to the wild swings of the global uranium market. Friday's selloff may have erased this week's recovery, but the structural case for nuclear fuel — and for Deep Yellow's project pipeline — has not gone away. The question is whether management can convert that promise into a final decision before investor patience runs any thinner.
