NKLR enters its August 25 earnings print with the call-skewed options positioning documented in Monday's preview note still firmly in place — but the borrow market has shifted meaningfully in just 24 hours, and that gap between bullish options and a still-elevated lending cost is the central tension heading into the week.
The clearest update since Monday's earnings-preview note is in the borrow. Cost to borrow dropped sharply on Tuesday to 25.5%, down from 39% the day before — a one-day fall of roughly a third. That brings CTB to its lowest level in three weeks, though it remains more than double where it was in early July. Availability has also continued to ease, now at 38% compared to the near-zero reading on August 5 when the pool was almost entirely lent out. The direction of travel is meaningfully looser, but 38% availability still represents a constrained lending environment — roughly one share available for every two and a half currently borrowed. Short interest dipped another 3% on Tuesday to 3.0% of the free float, extending a week-long retreat that has taken shorts down from a recent peak above 3.4% of float on August 11.
Options positioning remains the standout bull signal. The put/call ratio held at 0.79 Tuesday — still more than two standard deviations below its 20-day average of 0.95, and still the most call-heavy reading in the past year. The 52-week low on the PCR is 0.0, but the current reading represents a decisive break from July's defensive stance, when the ratio was trading above 1.20 for much of the month. The ORTEX short score has also eased off its recent peak: it registered 72.7 Tuesday, down from 79.2 on August 5 and from 75.5 as recently as August 11. The direction of the score — lower — aligns with the short-interest retreat and borrow loosening, even if the absolute level remains elevated.
The Street picture warrants caution in interpretation. Analyst data is stale — the consensus buy rating and mean price target of $16.80 reflect information as of February 2026, making those figures unreliable at the current $5.86 price. The most recent action on record is HC Wainwright's July reiteration of a Buy with a $25 target, which implies substantial upside on paper but dates from well before the stock's subsequent volatility. Valuation multiples tell a loss-making story: the price-to-earnings ratio runs negative at roughly -23x and EV/EBITDA is negative at -21.8x, consistent with a pre-profit growth name. Price-to-book has expanded 25% over the past month to 1.9x, tracking the stock's 28% one-month price gain to $5.86.
The peer backdrop on Tuesday was uniformly weak. SMR fell 6% on the day and lost 12.6% over the week. NNE dropped 6.8% Tuesday. CHPT gave back 5.3%. Against that peer pressure, NKLR's 2.2% single-day decline looks relatively contained, and its flat one-week performance compares favourably with most of the correlated names. That relative resilience, against a sector that sold off hard, adds texture to the call-heavy options positioning.
Earnings history for NKLR is uniformly negative on the first-day reaction: the last four announcements produced moves of -2.4%, -6.1%, -1.6%, and -15.1% on the day of the print, with only one showing meaningful five-day recovery. The August 25 print is therefore the critical test of whether the bullish options repositioning of the past two weeks — and the notable easing of borrow costs Tuesday — reflects genuine confidence in the forthcoming result, or simply short-term momentum chasing into an event that has historically punished the stock.
