SPAC IPO closes with $460M in trust; 24–27 month clock starts.

Bain Capital GSS Investment Corp. completed a SPAC IPO of 46,000,000 units at $10.00 each, plus a sponsor purchase of 900,000 private units. Each unit carries one share and one-fifth of a warrant; whole warrants are exercisable at $11.50.

Gross proceeds of $460,000,000 were deposited into a trust, consistent with SPAC structures. Release of funds is tied to a business combination, specified redemption events, or shareholder-approved charter amendments that affect redemption timing/rights.

The operating window is 24 months from IPO closing, extendable to 27 months if a letter of intent is executed. Actual impact depends on identifying and closing a qualifying transaction within this timeframe under the stated terms.
