Southport Acquisition Corp. II PORTU

We are a blank check company incorporated on July 8, 2026, as a Cayman Islands exempted company and formed for the purpose of effecting a merger, amalgamation, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities, which we refer to throughout this prospectus as our initial business combination. We have not selected any business combination target and we have not, nor has anyone on our behalf, initiated any substantive discussions, directly or indirectly, with any business combination target. We may pursue an initial business combination in any business, industry, sector or geographic location. While we may pursue an initial business combination in any business, industry, sector or geographic location, we intend to focus our search on the artificial intelligence sector. Our objective is to identify and acquire a high-quality artificial intelligence company that we believe is capable of succeeding as a public company. Our search will focus on businesses that are already generating meaningful revenue, solving mission-critical customer problems and operating in segments where we believe durable public-market leaders are likely to emerge. We intend to concentrate our initial sourcing efforts on five areas: enterprise AI applications and workflow automation; AI data, security and governance; AI infrastructure and enabling technologies; industrial AI, robotics and intelligent automation; and healthcare AI and life-sciences software. Our management team is led by Jeb Spencer, our Chairman, Chief Executive Officer and Chief Financial Officer, and Griffith Gates, our President and Chief Operating Officer. Mr. Spencer has more than two decades of experience as a chief executive officer, software investor and public and private company director. During his career, he has invested in and served on the boards of more than 15 software companies that ultimately completed strategic or financial exits, including Ellie Mae, Docupace, SimpleNexus, Del Mar DataTrac, Accordent Technologies and SmartAction. He also served on the board of Ellie Mae and chaired its M&A Committee during a period of significant growth that culminated in the company’s acquisition by Thoma Bravo. Mr. Gates most recently served as Chief Revenue Officer of Capital Gurus, a private financial technology company, and previously spent five years in finance and commercial roles at Space Exploration Technologies Corp. (“SpaceX”), where he worked across the company’s Starlink, Falcon 9 and Dragon programs. He began his career in private equity at Vance Street Capital and in investment banking in Citigroup’s Global Industrials Group. --- Our executive offices are located at 8 Bolling Place, Greenwich, CT 06830, and our telephone number is 917-503-9722.
