Harbour Island Acquisition I, a blank check company targeting technology components and infrastructure, robotics, and aerospace, lowered the proposed deal size for its upcoming IPO on Thursday.
The Palm Beach, FL-based company now plans to raise $80 million by offering 8 million units at $10. The company had previously filed to offer 10 million units at the same price. Each unit consists of one share of common stock and one whole warrant to purchase a share, exercisable at $11.50. At the revised deal size, Harbour Island Acquisition I will raise 20% less in proceeds than previously anticipated. The amended filing also disclosed an increase in the initial trust per share, from $10.075 to $10.10.
Harbour Island Acquisition I is led by CEO and Chairman McAndrew Rudisill, the CEO and Chairman of Forum Markets (Nasdaq: FRMM) and the former CIO of Bridger Aerospace Group Holdings (Nasdaq: BAER), and CFO Samuel Knipper, who has served as a contract CFO with Brio Financial Group. The SPAC plans to target businesses within the semiconductor, data infrastructure, robotics, and aerospace and defense sectors, along with the industrial materials supporting them.
Harbour Island Acquisition I was founded in 2026. It plans to list on the Nasdaq under the symbol HRIAU. Clear Street is the sole bookrunner on the deal.
