Fair value · Akari Therapeutics Plc (AKTX) · updated 2026-10-22 · from 20-F FY2025

Akari Therapeutics trades at $8.09. We are not reading assumptions out of that price: this is a depositary receipt whose filed share count matches neither the ordinary share count nor the number of receipts outstanding, so we cannot show its per-share figures are on the same scale as our price and these methods are withheld.

Everything below is unaffected: the filed statements, the filing they came from, and AKTX’s growth history are all as reported.

At least two methods need a usable value to draw a range with these inputs.

Range with preset inputs

No preset range for this company yet.

The two ranges are identical because every input sits on a preset.

We don’t tell you what AKTX is worth. Every tab OPENS on what today’s price implies for that method’s key assumption; you decide whether that assumption is reasonable — the growth matrix has AKTX’s filed history and the AI chat will reason it through with you — and the range you build is yours. Our presets are filed history and reference settings, never a recommendation.
