United States Antimony Corporation enters tomorrow's Q1 earnings call at 4:15 PM ET with one of the tightest short-positioning setups in the small-cap mining universe — a fully locked lending market, a CFO transition, and short interest running at more than a fifth of the free float.
Short positioning here is genuinely extreme, and the lending market reflects it. Short interest is running at roughly 20.3% of the free float — about 28.5 million shares — and availability has collapsed to under 2% of the outstanding short position. That means virtually every share available to borrow has already been lent out. Availability has matched its 52-week low for most of the past month, spending nearly every session since early April at or near zero. That is not a normal borrow condition. Cost to borrow, at 2.7%, has actually eased considerably from the 5%+ levels seen in early April — down close to 40% over the past month — which is a notable divergence. Borrow demand is near maximum, yet the price of that borrow has softened, suggesting the existing short book is rolling over cheaply rather than new shorts piling in at premium rates.
Short interest itself tells a nuanced story for the week. The headline number edged up 0.7% on Tuesday but fell roughly 6% across the five-day period, pulling back from a peak above 30 million shares touched in late April and early May. The ORTEX short score, at 70.0, has drifted lower from 70.5 a week ago — still elevated, ranking in just the 2nd percentile among peers on the short score scale, but the directional drift is marginally less aggressive than the peak. Options positioning leans slightly more defensive than usual: the put/call ratio is 0.26, running above its 20-day mean of 0.23 and roughly 1.7 standard deviations elevated. Still, the absolute PCR level remains low, sitting well below the 52-week high of 0.73. Overall, positioning is tight rather than panicked — the lending market says capacity is exhausted, but the cost of that position is easing.
The Street view rests on a single recent data point. HC Wainwright raised its price target to $11.50 from $10.25 in late March while maintaining its Buy rating, citing the dramatic re-rating in antimony pricing — from roughly $6 per pound to close to $29 per pound year-over-year — and a 12% lift in sales volumes. The analyst's mean target of $12.67 carries roughly 20% upside to Tuesday's close of $10.50. Bulls point to management's reiterated 2026 revenue target of $125 million and domestic supply investments in Alaska and Montana. Bears flag the net loss of $3.9 million in the most recent quarter, driven heavily by share-based compensation, and the risk that geopolitical supply disruptions could unwind as fast as they appeared. The EV/EBITDA multiple has compressed sharply — down roughly 33% in 30 days to around 91.7x — which reflects the price rally of the past month outrunning earnings recovery, not a fundamental cheapening. The stock is up 25.6% over the past month and closed Tuesday at $10.50, ending the week down 5.8%.
Management changes add another layer of uncertainty into the print. The company appointed Shawn Winkler as interim CFO on May 4, replacing Richard Isaak, with an 8-K filed the same day. An interim CFO is rarely a comforting signal ahead of an earnings call, and a Q1 print will be his first public facing event in the role. Insider activity from late March and early April reinforces the mixed picture: executive director Lloyd Bardswich and director Blaise Aguirre sold a combined roughly $1.6 million in shares between March 26 and April 2, mostly in the $8–9 range — well below today's price. Those sales look different in hindsight but remain the most recent disclosed insider activity, and the net insider position over 90 days is a positive $7.7 million, suggesting the broader insider base added more than it trimmed.
The most comparable recent event was the March 19 earnings release, which sent the stock down 12.6% on the day and a further 5.2% over the following week. Against that backdrop, the Q1 print tomorrow — and the first call under an interim CFO — is where the next chapter for UAMY gets written. Close peers MP Materials and USAR both fell on the week, dropping 3.6% and 6.8% respectively, suggesting sector-wide pressure on critical-minerals names. With availability fully exhausted and short interest still near 20%, the reaction to tomorrow's numbers will determine whether this week's modest short covering extends — or reverses.
