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.

Actionable Insight

No further trading action required — APLS shares are no longer publicly traded. Monitor CVR-related events for Biogen's acquisition consideration.

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.
