Akari Therapeutics, a pre‑clinical biotechnology company focused on antibody‑drug conjugates (ADCs), completed a $5 million equity financing that will extend its cash runway beyond September 2025 and provide working capital for continued research and development of its next‑generation ADC platform.
The transaction consists of a registered direct offering of 10,043,774 American Depositary Shares (ADSs) priced at $0.3883 per ADS and a concurrent private placement of 2,564,000 ADSs priced at $0.4041 per ADS. Each ADS represents 2,000 ordinary shares, and the private placement includes unregistered Series G warrants exercisable at the same price as the ADSs. In addition, the company converted roughly $2.5 million of outstanding debt into pre‑funded warrants, reducing its debt burden and improving its capital structure.
Akari’s cash balance stood at $2.58 million as of March 31 2025, while its accumulated deficit was approximately $251 million. The new proceeds will be used primarily for continued R&D of its PH1 payload technology, which is a spliceosome‑modulating agent intended to enhance the potency and selectivity of ADCs, as well as for general corporate purposes and working capital. The financing is expected to close on or about December 17 2025, subject to customary closing conditions.
The deal is significant because it provides the company with the liquidity needed to pursue key preclinical milestones and to position itself for future clinical development. Insider participation in the offering—through the purchase of ADSs and warrants by directors, officers, and executive management—signals confidence in the company’s technology and strategy. The financing also underscores the competitive pressure in the ADC market, where early‑stage companies must secure capital to sustain development timelines and to compete with larger, better‑funded peers.
By extending its runway, Akari gains additional time to advance its ADC pipeline, potentially accelerating the transition from preclinical to clinical stages. The capital raise also improves the company’s balance sheet, reducing leverage and providing a buffer against the high costs associated with drug development. Overall, the financing strengthens Akari’s position to pursue strategic partnerships and to continue investing in its proprietary PH1 payload, which could differentiate its ADC candidates in a crowded market.
