Rhea-AI Summary

Passage Bio, Inc. (PASG) has executed a material corporate action by approving and implementing a 1-for-20 reverse stock split of its common stock. The company filed a Certificate of Amendment with the Delaware Secretary of State on 11 July 2025 to amend its Amended and Restated Certificate of Incorporation. The split will become effective at 12:01 a.m. (ET) on 14 July 2025 and the shares will begin trading on a split-adjusted basis the same day under a new CUSIP number, 702712 209.

The board’s decision follows prior stockholder authorization (May 28, 2025) that granted discretion for a reverse split ratio between 1-for-5 and 1-for-50; on 26 June 2025 the board selected the 1-for-20 ratio. Immediately prior to the split, approximately 62,405,898 shares were outstanding; post-split, this number will be approximately 3,120,295.

Key mechanics include: every 20 shares automatically combine into one share; no fractional shares will be issued—amounts will be rounded up to the nearest whole share. The action does not affect the par value, authorized share count, voting rights, or relative ownership percentages, though proportionate adjustments will be made to all outstanding equity awards and share reserve plans.

A press release announcing the action is filed as Exhibit 99.1. Additional documentation includes the full Certificate of Amendment (Exhibit 3.1) and related XBRL cover data (Exhibit 104).

Rhea-AI Summary

Amendment No. 7 to Schedule 13D reveals that OrbiMed Advisors LLC and OrbiMed Capital GP VII LLC, through OrbiMed Private Investments VII, LP ("OPI VII"), now beneficially own 5,923,534 Passage Bio (PASG) common shares, equal to 9.5 % of the 62.15 million shares outstanding. The update is required because the group’s ownership fell more than one percentage point since the prior amendment.

Share-sale activity: Between 24 June and 9 July 2025, OPI VII sold an aggregate 726,466 shares in open-market transactions at prices ranging from $0.33 to $0.48 per share. The largest daily sale was 231,600 shares on 24 June at $0.35. These disposals reduced the position to its current level.

OrbiMed retains shared voting and dispositive power over the entire 5.9 million-share stake via OPI VII. No other concrete plans—such as seeking board seats, launching a merger, or altering Passage Bio’s capital structure—are disclosed, but the filing states that OrbiMed will continue to monitor the company and may buy or sell shares as market conditions warrant.

Key take-aways for investors:

  • A prominent life-sciences investor has trimmed its holding yet remains Passage Bio’s largest known shareholder.
  • Sales occurred at prices well below $1, highlighting persistent share-price weakness.
  • With 9.5 % ownership, OrbiMed still has potential influence, but the reduced stake may lessen alignment incentives.
