Executive Summary
Apellis Pharmaceuticals filed Form 15-12G to terminate its SEC registration and suspend reporting obligations, effective May 26, 2026, following the completion of Biogen's acquisition. The company's common stock was delisted via a prior 25-NSE filing, and there is now only one holder of record, reflecting the acquisition's consummation. This is a procedural step after the merger, with no further impact on public shareholders.
Key Facts
- Form 15-12G filed to terminate registration under Section 12(g) of the Securities Exchange Act.
- Approximate number of holders of record as of certification date: one (1).
- Deregistration follows the completion of Biogen's acquisition (previous 25-NSE delisting on May 14, 2026).
- Common stock will cease SEC reporting obligations effective immediately.
Financial Impact
Shareholders received $41.00 per share plus contingent value rights (CVRs) from the Biogen acquisition; no new financial impact from this filing.
Risk Factors
- CVR value may fluctuate based on Apellis' clinical and regulatory outcomes under Biogen.
- Future litigation or liabilities may arise post-deregistration with limited public disclosure.
