Merlin Labs, Inc. and Inflection Point Acquisition Corp. IV Announce Upsizing of PIPE Investment to More Than $200 Million

Inflection Point and investors increase PIPE commitments to more than $200 million, including over $85 million of pre-funded PIPE capital

Boston, Mass. — November 17, 2025 — Merlin Labs, Inc. (“Merlin”), a leading developer of assured, autonomous flight technology for defense customers, and Inflection Point Acquisition Corp. IV (Nasdaq: BACQ) (“Inflection Point”) today announced a significant increase to their previously disclosed private investment in public equity (“PIPE”). The increase comes from both new investors and existing investors increasing their commitments, bringing total PIPE commitments to more than $200 million, of which over $85 million has already been funded.

This represents a substantial increase from the more than $125 million in committed capital announced at the signing of the Business Combination Agreement on August 13, 2025, and will further strengthen Merlin’s balance sheet ahead of and upon closing the proposed transaction, which is expected to occur in early 2026.

As previously disclosed, the transaction is expected to drive rapid capability delivery for customers and improve Merlin’s strategic acquisition pipeline. It positions the company to scale its AI-powered autonomy stack across multiple aircraft types, deepen engagements with government customers, and advance civil certification pathways, bolstering national security in a rapidly evolving defense landscape.

“Merlin’s expanded PIPE is a validation of its continued execution on its business plan and the critical role it holds in the nation’s aerospace and defense industries,” said Michael Blitzer, Chairman of Inflection Point, “the company’s AI powered software is quickly becoming a strategically important technology asset that has been adopted by leading companies such as GE Aerospace and Northrop Grumman.”

“With this upsized PIPE, we’re reinforcing our commitment to deliver the world’s first defense-grade autonomy stack and to accelerate our expansion across both military and civil aviation,” said Matt George, CEO and founder of Merlin. “This additional capital reflects the strong momentum we’ve built since announcing our SPAC transaction and the confidence investors have in our revenue growth, scalability, and path toward becoming a public company.”
