Akari Therapeutics heads into tomorrow's earnings report having shed nearly half its value in a week, making the print less a routine update and more a reckoning.
The price collapse is the dominant fact here. The stock closed at $3.06 on Tuesday — down 40.6% on the day and 45.6% over the week. That is a pre-earnings rout, not a post-earnings one. It follows a more moderate 20% decline over the prior month, suggesting the selling accelerated sharply in the final days before the report. For a clinical-stage biotech with zero revenue and a net loss running at roughly $15.2 million annually, the share price at any given moment is almost entirely a function of trial expectations and cash runway — which makes the scale of this move notable.
The short interest story is quiet by comparison, which is itself meaningful. Short interest against the free float is effectively negligible — under 0.05% — and it has been falling, dropping around 16% over the past week and more than 80% over the past month. The borrow market is also loosening. Availability remains ample, and cost to borrow has eased to roughly 9.3% from above 11% earlier in May. None of this resembles a stock that short sellers are piling into ahead of bad news. The selling pressure, whatever its source, is not coming from the short side.
Past earnings reactions for AKTX have been volatile and asymmetric. The April 2026 print produced a 10.6% gain on the day and a 25% gain over the following five days. The November 2025 event saw a 9.8% one-day decline but only modest further erosion. The point is not that any pattern holds — it is that the stock has historically moved sharply in both directions around catalysts, and the entry point this time is already dramatically lower.
The CEO, Abizer Gaslightwala, was a persistent open-market buyer through mid-2025 and into August — accumulating shares at prices between $0.90 and $1.27. Those purchases, made at a fraction of Tuesday's close (even after the crash), are a reminder of how far this stock has already traveled. The insider data is now stale by more than eight months, so it cannot be read as a near-term signal, but it does speak to the directional conviction management held at much lower levels.
Tomorrow's print will test whether whatever triggered this week's collapse — trial data, cash position, or something else entirely — is already in the price.
