Shares in NexGen Energy Ltd (ASX: NXG) fell around 5% today after the Canadian uranium developer reported a third-quarter loss of C$129 million, widening significantly from a profit of C$10 million in the same period a year ago.
NextGen Energy shares are trading at a share price of $12.80 on the ASX at the time of writing.
The company's quarterly report provided investors with a closer look at the progress made toward developing its massive Rook I uranium project, one of the most promising deposits in the world.
However, despite long-term optimism in the uranium market, today's results highlighted why an investment in NexGen Energy remains a patience game.
Big plans ahead
NexGen's flagship Rook I project in Canada's Athabasca Basin could become a global powerhouse, potentially producing up to 30 million pounds of uranium per year once operational. But it's still in the development stage, and that means a longer period of heavy spending before any revenue comes.
In the September quarter, NexGen's losses were primarily driven by a C$95 million mark-to-market loss on convertible debentures and an additional C$11 million in interest expense on those instruments.
On the balance sheet, the company ended the quarter with C$306 million in cash and exploration assets worth over C$731 million to support the convertible debentures of $592 million.
This underscores how capital-intensive it is to bring Rook I to life, but NexGen is approaching the final steps before a mining licence can be issued. It achieved a key milestone this year when the Canadian Nuclear Safety Commission accepted its final Environmental Impact Statement and set public hearing dates for late 2025 and early 2026.
That's a positive sign, but with no revenue and pre-production capital costs now estimated at roughly C$2.2 billion, investors are grappling with how to underwrite their investment given the level of dilution or debt required to reach production.
Foolish bottom line
NexGen remains one of the most strategically significant uranium developers globally, and the scale of Rook I has the potential to dwarf ASX peers like Paladin Energy Ltd (ASX: PDN) and Boss Energy Ltd (ASX: BOE).
Today's 5% slide, however, suggests that while the uranium story remains hot, investors want to see shovels in the ground, not just feasibility studies and financing rounds. When that day comes, NexGen shares could really soar.
