Rainier Acquisition (RNAQ) 10% Owner Jonas Grossman Buys Stock

What Happened

• Jonas Grossman, a 10% owner (sole managing member of Ravenna 7 LLC), purchased Units in Rainier Acquisition Corp in a private placement on 2026-09-02. The filing shows acquisition of 5,625 Units (each Unit = 1 Class A ordinary share + 1/4 warrant) at $10.00 per Unit for $56,250, plus a derivative line reflecting 1,407 warrant interests at $10.00 for $14,070 — total cash paid $70,320. This is a purchase transaction (not a sale).

Key Details

• Transaction date: 2026-09-02
• Price: $10.00 per Unit; totals: $56,250 (5,625 Units/shares) + $14,070 (1,407 derivative warrant units) = $70,320
• Form type: Private placement purchase of Units from the issuer (per footnote)
• Shares owned after transaction: Not specified in the provided filing extract
• Beneficial ownership note: Shares are held directly by Ravenna 7 LLC; Mr. Grossman is sole managing member and disclaims beneficial ownership except to the extent of any pecuniary interest (footnote)
• Filing timing: Reported and filed with the SEC on 2026-09-02 (same-day filing per provided dates)

Context

• The Units include one-quarter of a warrant each; the reported 1,407 derivative units reflect the warrant component. Each whole warrant (when exercisable) allows purchase of one Class A share at $11.50 per share, subject to adjustment (see footnote).
• Warrants become exercisable on the later of (i) August 28, 2026 and (ii) the completion of the issuer’s initial business combination, and expire five years after that business combination (or earlier upon redemption/liquidation).
• As a 10% owner transacting through an LLC, this is institutional/insider ownership disclosure rather than an executive payroll transaction; the filing disclaims direct beneficial ownership by Mr. Grossman except for any pecuniary interest.
