Energy Fuels heads into its June 24 earnings print with short interest rising sharply — and the stock lagging behind a uranium sector that is broadly moving higher.
Short sellers have been accumulating positions at an accelerating pace. Short interest jumped 16% in a single session on June 19, pushing the total to 3.4% of free float — up 19% on the week and 20% over the past month. That is a meaningful and sustained build, not a one-day blip. The borrow market remains accessible: availability is 31%, which is tight but not stressed, and the cost to borrow is modest at around 1.1%. The 52-week peak for borrow availability was nearly 93%, so the current lending pool has tightened considerably from that high, though it has eased from an even tighter 15–20% range seen in late May. Borrowing costs have risen 29% over the past month even as they dipped slightly on the week — a sign that demand for shorts is building without yet triggering a full squeeze dynamic.
That short-side pressure sits in contrast to what peers are doing. Over the past week, uranium and critical minerals names have broadly rallied: UEC gained 8.9%, DML rose 10.7%, and added 8.4%. Energy Fuels managed only a 4.6% weekly gain and fell 2.3% on Monday — the weakest performance in its peer group. The ORTEX short score crossed above 50 for the first time in weeks on June 19, marking a directional shift in bearish pressure even as the sector wind blew the other way.
The fundamental tension heading into the print is real. The bull case rests on Energy Fuels' diversification into rare earth processing — a strategically attractive pivot given critical minerals policy tailwinds — and its track record of exceeding uranium production guidance. Van Eck Associates, the largest reported holder at 6.2% of shares, added over 3.3 million shares in the most recent filing period, signalling conviction from a specialist resource manager. Bears focus on the financial profile: the company carries a deeply negative earnings yield and an EV/EBITDA multiple that, while compressing sharply over 30 days, remains at levels that price in considerable optimism. Quality metrics are weak — negative ROA, negative free cash flow, and a low Piotroski score — all of which leave the stock exposed if the narrative on rare earth timelines slips.
The earnings release will test whether the company's diversification story is gaining traction fast enough to justify the premium embedded in the stock, at a moment when short sellers are signalling growing doubt and the wider sector is beginning to leave EFR behind.
