Rainier Acquisition Corp Announces Separate Trading of Shares and Warrants

What Happened

• Rainier Acquisition Corp filed an 8-K on September 11, 2026, announcing that holders of the units issued in its IPO may elect to separate each Unit (one Class A ordinary share + 1/4 warrant) so the Class A ordinary shares and warrants can trade separately. The separate securities will begin trading on the Nasdaq Capital Market on September 15, 2026.

Key Details

• Each Unit originally contains one Class A ordinary share and one-quarter of one redeemable warrant; only whole warrants will trade after separation (no fractional warrants issued).
• Each whole warrant entitles the holder to purchase one Class A ordinary share at an $11.50 exercise price.
• Separation elections commence September 14, 2026; after separation, shares will trade as "RNAQ" and warrants as "RNAQW"; unsplit Units continue to trade as "RNAQU."
• Holders must have their brokers contact Continental Stock Transfer & Trust Company (the transfer agent) to effect the separation. A press release was attached as Exhibit 99.1 to the filing.

Why It Matters

• Separating the shares and warrants lets the market value and trade the equity and the warrant portions independently, which can increase liquidity and allow investors to buy or sell just the shares or just the warrants.
• Practical for holders: you must act through your broker and be aware that fractional warrants will not be issued (fractions will be eliminated), and the warrants carry an $11.50 exercise price that matters if you plan to exercise later.
• This is an operational/structural update — not a change to company financials or management — but important for trading and portfolio decisions for current and prospective investors.
