Yorkville Acquisition Corp. 8-K

What Happened Yorkville Acquisition Corp. filed an 8-K reporting that Kevin McGurn resigned as Chief Executive Officer and director, effective April 22, 2026. The board immediately appointed Troy Rillo, who has served as the Company’s Chief Financial Officer since August 2025, as Chief Executive Officer effective the same date. The filing was made on April 24, 2026.

Key Details

• Kevin McGurn’s resignation was effective April 22, 2026 and was not due to any dispute or disagreement with the Company.
• Troy Rillo (age 57) was appointed CEO on April 22, 2026 and will continue to serve as CFO.
• Rillo has been CFO since August 2025, is a partner at Yorkville Advisors (since 2004), and holds leadership roles at affiliated firms including Yorkville Securities LLC and Yorkville America, LLC.
• The filing states there are no new compensation agreements, material contracts, or related-party transactions entered into in connection with Rillo’s appointment; however, as a partner of an affiliate of the Sponsor, he may have an indirect interest in existing Sponsor arrangements previously disclosed.

Why It Matters A CEO change is a material leadership shift that can affect strategy and execution. For investors, the appointment of an internal executive (the current CFO) suggests continuity in finance and operations. The company notes no disagreement prompted the resignation and no new compensation or arrangements tied to the appointment, but Rillo’s affiliation with the Sponsor’s firm is disclosed as a potential indirect interest — a governance detail investors may watch for in future filings.
