Grigorios "Greg" Kapenis is a financial executive and director currently serving as Chief Financial Officer, Principal Financial and Accounting Officer, and Board Director of OneIM Acquisition Corp., a blank-check company incorporated in the Cayman Islands and headquartered at 390 Park Avenue, 11th Floor, New York, NY. OneIM Acquisition Corp. was formed in 2025 to pursue a merger, share exchange, asset acquisition, or similar business combination, leveraging the experience of its management team across diverse asset classes. Kapenis joined the SPAC in 2025, with regulatory filings indicating his appointment effective around April 1, 2025, and his LinkedIn profile listing his tenure as beginning September 2025. He serves alongside Chief Executive Officer and Director Ioannis Pipilis, with independent directors Mark DiPaolo and Antony Sheriff rounding out the board. The SPAC priced its $250 million initial public offering on January 13, 2026, with units trading on the Nasdaq Global Market under the symbol "OIMAU" beginning January 14, 2026. The offering closed on January 15, 2026, at $287.5 million after the underwriters fully exercised their over-allotment option, bringing the total to 28,750,000 units at $10.00 per unit. Deutsche Bank Securities served as sole book-running manager, with Reed Smith LLP as issuer's counsel and WithumSmith+Brown, PC as auditor. Separate trading of the Class A ordinary shares and warrants under symbols "OIM" and "OIMAW" commenced March 6, 2026.
Prior to his role at OneIM Acquisition Corp., Kapenis built an extensive career in finance and accounting primarily in London. He served as Chief Financial Officer at One Investment Management from approximately September 2019 to October 2022, the affiliated investment firm tied to the OneIM group. He also held the position of Director of Accounting at SoftBank Investment Advisers, the London-based venture capital and private equity arm of SoftBank's Vision Fund. In connection with that role, he was appointed as a director of SVF Investments (UK) Limited on September 8, 2022, a position he held briefly until his termination on October 18, 2022, when he was succeeded by Alexander Nawrat. His professional background reflects deep expertise in financial reporting, accounting controls, and investment management operations across both traditional asset management and large-scale technology investment platforms.
Kapenis is a Chartered Accountant, having qualified through ICAS (Institute of Chartered Accountants of Scotland) between 2011 and 2014. He was born in 1986 and, while the SPAC he leads is based in New York, multiple sources indicate he has been based in London, United Kingdom, throughout much of his career. His profile on Bloomberg lists him under the name "Greg" Kapenis, and he is identified across SEC filings, company press releases, and financial data platforms as a key member of OneIM Acquisition Corp.'s leadership team. As of the latest filings, OneIM Acquisition Corp. continues to search for a suitable business combination target, with Kapenis overseeing the financial and accounting functions critical to the SPAC's regulatory compliance and capital deployment strategy.
This record is keyed to SEC CIK 0002086726 — the identifier this person files under in their own name. Every vehicle above is a filing made under that CIK, so “the same person on two shells” is a fact about an SEC identifier rather than about a name that happens to match.
Roles are the strings the filings used, in the order they were filed. Nothing on this page ranks them, infers seniority, or offers a reason why any two of these names recur — a recurrence is a count, and the filings that produced it are linked beside every row. We also hold 7 institutional-holder rows on these vehicles, under 5 distinct name strings, and none of them is counted across vehicles: that table has no CIK column, and matching holders by name would merge firms that are not the same firm.
