Thomas Sweeney is a financial executive who served as Chief Financial Officer and Principal Accounting Officer of Oaktree Acquisition Corp. III Life Sciences (NYSE: OACC), a special purpose acquisition company sponsored by Oaktree Capital Management. He was appointed to the CFO role on June 3, 2025, succeeding Courtney Conigliaro, and served as the company's principal financial officer until his resignation effective October 29, 2025, at which point the Board appointed George A. Martinez as his replacement. His departure was explicitly noted as unrelated to any disagreement with the Board or management; he resigned to pursue other professional opportunities. During his tenure, Sweeney held insider reporting obligations with the SEC and was listed as a reporting owner of OACC shares, with a mailing address in Stamford, Connecticut.
Beyond his SPAC role, Sweeney's professional background includes serving as a Managing Director at Antares Capital LP, a middle-market lending platform affiliated with Oaktree Capital Management. He has also been identified as Controller and Assistant Treasurer within the Oaktree organization, reflecting a career rooted in financial reporting, accounting, and treasury functions at major alternative asset management firms. His educational credentials include a Bachelor of Science in Accounting, which he earned between 2001 and 2005, consistent with his career trajectory in finance and accounting leadership roles.
Sweeney's appointment to OACC came at a transitional moment for the SPAC, as the vehicle sought to identify and complete a business combination in the life sciences sector. His relatively brief tenure—approximately five months from June to late October 2025—spanned a period during which the company continued to evaluate potential acquisition targets. While no completed business combination or notable exit has been publicly attributed to his time as CFO, his selection for the role underscored Oaktree's confidence in his financial oversight capabilities, drawing on his broader experience at Antares Capital and within the Oaktree ecosystem. His professional network and career history suggest a focus on private capital markets, corporate finance, and the operational financial management of investment vehicles.
This record is keyed to SEC CIK 0002073364 — 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 19 institutional-holder rows on these vehicles, under 12 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.
