Shares will move to the OTC or cease trading entirely as the company goes dark. Given only 5 holders of record, this is a definitive end to public market participation — any remaining CNTA equity is essentially illiquid. Traders should close any positions immediately; there is no future catalyst path that restores public reporting.

Executive Summary
Centessa Pharmaceuticals filed a Form 15-12G on July 6, 2026, to voluntarily deregister its ordinary shares and American Depositary Shares under Section 12(g) of the Exchange Act, terminating its SEC reporting obligations. The filing follows a Nasdaq delisting notice (Form 25-NSE) filed June 24, 2026, confirming a complete exit from public markets with only 5 holders of record. This represents a terminal liquidity event for remaining shareholders who will lose all public company transparency and most secondary trading access.
Key Facts
- Centessa Pharmaceuticals filed Form 15-12G to terminate registration under Section 12(g) of the Securities Exchange Act of 1934
- Deregistration covers both Ordinary Shares and American Depositary Shares (ADSs)
- Approximate number of holders of record as of certification date: 5
- Filed concurrently with a Form 25-NSE (delisting notice) from June 24, 2026, confirming the securities were already being removed from Nasdaq
- No securities remain registered; no other classes have a duty to file reports under Section 13(a) or 15(d)
Financial Impact
Complete loss of SEC reporting transparency; no public market liquidity for remaining shares; no financial figures disclosed in filing
Risk Factors
- Complete loss of SEC financial reporting creates information asymmetry for remaining shareholders
- Illiquidity — no exchange listing means wide bid-ask spreads or no secondary market at all
- Potential for zero return on remaining equity if no going-private transaction accompanies the deregistration
