JAB Acquisition Corp I is a Cayman Islands exempted blank check company formed in 2026 with headquarters in Englewood Cliffs, New Jersey, that operates as a special purpose acquisition company focused on effecting a merger, amalgamation, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses, with an emphasis on technology, healthcare and logistics targets and an intended enterprise value of $150 million or greater. The company has not selected a business combination target and has not initiated substantive discussions with any target. Its securities include units, Class A ordinary shares, warrants and rights; each unit consists of one Class A ordinary share, one redeemable warrant exercisable for one Class A ordinary share at $11.50 per share, and one right to receive one-fourth of one Class A ordinary share. The company completed its initial public offering in June 2026, selling 17.25 million units including overallotment, alongside a private placement of 260,000 private units to its sponsor, JAB Acquisition Sponsor I, LLC, and it holds the offering proceeds in trust for a future initial business combination. In the last year, the company entered into a trademark settlement agreement to resolve a name and trading-symbol dispute and has filed to change its Nasdaq ticker symbols to ATLQ for Class A ordinary shares, ATLQU for units, ATLQW for warrants and ATLQR for rights, with an intended name change to Atlantic Acquisition Corp I subject to board and shareholder approval. The company may extend its initial business combination deadline by up to two three-month periods upon additional trust deposits and remains an emerging growth company and smaller reporting company.
