Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On July 20, 2026, the Board of Directors (the “Board”) of Bleichroeder Acquisition Corp. III, a Cayman Islands exempted company (the “Company”), appointed Constantine Dakolias as a director, effective immediately. Mr. Dakolias qualifies as an independent director. Mr. Dakolias has been appointed to serve as the member of the audit committee of the Board.

Mr. Dakolias, age 60, has over three decades of investment, credit and asset management experience. Mr. Dakolias spent nearly 25 years at Fortress Investment Group, a leading global investment manager, where he most recently served as Co-Chairman and previously served as Co-Chief Investment Officer of Fortress's credit and real estate funds. Prior to his tenure at Fortress, Mr. Dakolias was a co-founder and Managing Director of American Commercial Capital LLC, a specialty finance company, and Coronado Advisors, an SEC-registered broker-dealer, both of which were sold to Wells Fargo & Co. in 2001. Mr. Dakolias serves on the Board of Trustees for Columbia University, on the Board of Visitors for the School of Engineering and Applied Science and on Columbia’s Athletic Leadership Committee. Mr. Dakolias also serves on the Board of Trustees for the American School of Classical Studies at Athens. Mr. Dakolias is a co-founder and member of the Executive Committee of The Hellenic Initiative and a member of the Council on Foreign Relations. Mr. Dakolias received a B.S. in Physics from Columbia University. We believe Mr. Dakolias is well-qualified to serve as a director due to his extensive investment, credit and asset management experience, as well as his leadership experience at global investment management and specialty finance firms.

There are no family relationships between Mr. Dakolias and any director, executive officer, or person nominated or chosen by the Company to become an executive officer of the Company. There are no transactions between the Company and Mr. Dakolias that are subject to disclosure under Item 404(a) of Regulation S-K.

In connection with the appointment, the Company and Mr. Dakolias entered into a joinder to a letter agreement, as well as an indemnification agreement, which are substantially similar to the letter agreement and indemnification agreements, respectively, entered into by the current officers and directors of the Company.
