What ownership stake does Deep Track report in RAPT (RAPT)?
Deep Track and related reporting persons disclose beneficial ownership of 110,448 RAPT common shares, equal to 0.40% of the class as of December 31, 2025. They hold shared voting and dispositive power over all these shares.
How was the 0.40% ownership in RAPT (RAPT) calculated?
The 0.40% ownership is based on 27,710,871 RAPT common shares outstanding as of November 3, 2025, according to the company’s Form 10-Q. Dividing Deep Track’s 110,448 shares by this total yields the disclosed percentage of the class.
Who are the reporting persons in this RAPT (RAPT) Schedule 13G/A?
The filing lists three reporting persons: Deep Track Capital, LP, Deep Track Biotechnology Master Fund, Ltd., and David Kroin. Each reports the same 110,448 RAPT common shares as beneficially owned, with shared voting and shared dispositive power.
Does Deep Track seek control of RAPT (RAPT) through this stake?
The reporting persons certify the RAPT shares were not acquired and are not held for the purpose of changing or influencing control of the issuer. They also state the holdings are not in connection with any transaction having that control-related purpose or effect.
What does ‘ownership of 5 percent or less’ mean for RAPT (RAPT)?
The filing states “Ownership of 5 percent or less of a class,” confirming the reported 0.40% RAPT stake is below the 5% threshold. This language indicates the holding is relatively small compared with the total common stock outstanding.
What powers do the reporting persons have over RAPT (RAPT) shares?
The reporting persons disclose no sole voting or dispositive power and shared voting and dispositive power over 110,448 shares of RAPT common stock. This means decisions to vote or sell these shares are made on a shared, rather than individual, basis.
