On October 20, 2026, Praetorian Acquisition Corp. (the ‘Company’) implemented a planned leadership transition involving changes to the composition of its board of directors (the ‘Board’) and executive leadership, appointing a highly accomplished slate of directors and a Chief Financial Officer, as described below. Justin Di Rezze, M.D. will continue to serve as the Company’s Chief Executive Officer.
Director and Chief Financial Officer Departures
In connection with the planned leadership transition, on October 20, 2026, Nicole Seligman, Erica Dorfman and Alex Elias resigned as directors of the Company, effective October 20, 2026. Each of Ms. Seligman, Ms. Dorfman and Mr. Elias also served on the Audit Committee and Compensation Committee of the Board prior to their respective resignations.
In connection with the same transition, Peter Ondishin resigned as Chief Financial Officer and director of the Company, effective October 20, 2026.
None of the foregoing departures was the result of any dispute or disagreement with the Company, its management, the Board, or any committee of the Board on any matter relating to the operations, policies, or practices of the Company.
Appointment of New Directors and Officers
In connection with the planned leadership transition described above, on October 20, 2026, the Board appointed Roger L. Cloutier, Jimmy Vaiopoulos, Charles P. Garcia and Joseph Tonnos as directors of the Company, effective as of October 20, 2026. The Board also appointed Mr. Tonnos as Chief Financial Officer, succeeding Peter Ondishin. These appointments filled the four vacancies resulting from the planned resignations described above. Mr. Cloutier will serve as a Class I director and will serve until the Company’s first annual general meeting. Mr. Vaiopoulos will serve as a Class I director and will serve until the Company’s first annual general meeting. Mr. Tonnos will serve as a Class II director and will serve until the Company’s second annual general meeting. Mr. Garcia will serve as a Class III director and will serve until the Company’s third annual general meeting.
Lieutenant General (Ret.) Roger L. Cloutier Jr., 61, currently serves as a director of our Company. Since March 2026, Mr. Cloutier has served as Chief Business Officer of Nex42, a defense and dual-use business platform that connects advanced technologies with operational needs, contacts and market opportunities.

Exhibit 99.1
Di Rezze Family Office Names Joseph Tonnos Managing Director; Tonnos Becomes CFO of Two Nasdaq-Listed SPACs
Retired Army Lt. Gen. Roger L. Cloutier Jr., former commander of NATO Allied Land Command, joins both SPAC boards
SPAC sponsorship is one of several strategies for the single-family office, which invests only its own capital
MIAMI, Oct. 26, 2026 (GLOBE NEWSWIRE) -- Di Rezze Family Office, the single-family office of Arghavan and Justin Di Rezze, today announced that Joseph Tonnos has joined the office as Managing Director and will lead the office’s efforts across its direct investment portfolio. He joins a senior team of investment, capital markets and operating professionals.
Effective October 20, 2026, Mr. Tonnos also became Chief Financial Officer of Soren Acquisition Corp. (Nasdaq: SORN) and Praetorian Acquisition Corp. (Nasdaq: PTOR), two special purpose acquisition companies sponsored by principals of the office and will join the board of each company. Each company also appointed new independent directors.
“Joe brings significant financial markets and investment management experience to our team. He has worked across all aspects of the SPAC market since 2017, most notably as a six-time sponsor and as an investor, and he now leads finance and execution for Soren and Praetorian,” said Arghavan Di Rezze, Principal of Di Rezze Family Office. “Our new independent directors bring capital markets, public-company finance and operating experience, and they answer to shareholders, which makes the right team to have in place for a company when it is ready to go public.”
Mr. Tonnos brings more than 15 years of experience in investment management, corporate finance, capital markets and transaction structuring. Most recently, he was a Managing Director at Roth Capital Partners, LLC, and before that a Principal and Associate Portfolio Manager at Meteora Capital, LLC.
Soren appointed Lieutenant General (Ret.) Roger L. Cloutier Jr. and Austin Criden as independent directors. Praetorian appointed Mr. Cloutier, Jimmy Vaiopoulos and Charles P. Garcia as independent directors.
Mr. Cloutier retired from the U.S. Army as a Lieutenant General after 34 years of service and commanded NATO Allied Land Command from 2020 to 2022. Mr. Criden serves as a consultant to West2East Empire, a brand management and media production company and has held other positions as an operator and investment banker. Mr. Vaiopoulos is Chief Financial Officer and Co-Founder of Stack Capital Group Inc. and previously served as Chief Financial Officer and Interim Chief Executive Officer of Hut 8 Mining Corp., the predecessor of Hut 8 Corp. Mr. Garcia is Managing Partner of R360 Management Inc. and a former director of Winn-Dixie Stores, Inc., where he was the financial expert of its audit committee.
Di Rezze Family Office invests only its own capital across multiple strategies, including pre-IPO minority investments in private growth companies, structured investments in public companies and the sponsorship of special purpose acquisition companies. Soren and Praetorian, the two SPACs sponsored by its principals, together hold more than $500 million in trust.
“As founders and operators ourselves, Arghavan and I look at a SPAC through a founder’s eyes,” said Justin Di Rezze, co-founder of Di Rezze Family Office. “For the right company, it is a powerful way to access the public capital markets, maintain control of the business and take it to the next level. We seek to add value from our entire platform and approach a business combination with transparency as long-term investors. We are ready to partner with founders, operators and stakeholders prepared to take the next step.”
Further details are available in each company’s Current Report on Form 8-K.
