Bain Capital GSS Investment, a blank check company formed by Bain Capital targeting long-term growth, filed on Tuesday with the SEC to raise up to $400 million in an initial public offering.
The Boston, MA-based company plans to raise $400 million by offering 40 million units at a price of $10. Each unit contains one share of common stock and one-fifth of one warrant, exercisable at $11.50. At the proposed deal size, Bain Capital GSS Investment would command a market cap of $509 million.
The company is being led by CEO and Director Angelo Rufino, who is currently a Partner at Bain Capital, previously serving as a Managing Partner at Brookfield Asset Management, and CFO Patrick Dury, who currently serves as CFO of Bain Capital Special Situations, and previously served as interim CFO of Bain Capital Specialty Finance. Previously, Bain Capital Life Sciences formed a SPAC in 2020, BCLS Acquisition (BLSA), which liquidated in 2022 after failing to consummate a merger. Bain Capital GSS Investment plans to focus on companies that have long-term growth potential.
The Boston, MA-based company was founded in 2025 and plans to list on the NYSE under the symbol BCSS.U. Citi is the sole bookrunner on the deal.
