FOC (19 JUL 2026 · in execution): The IOC construct consolidates into three Portfolio Acquisition Executives. Per the 09 JUN 2026 All Hands, the formal portfolios are PAE Medical Systems (MS), PAE Medical Products (MP), and PAE Medical Digital Solutions (MDS). PAE MDS absorbs the PEO DHMS + PEO Medical Systems portfolios; both PEOs are actively transitioning personnel, funding, and the ICS/MST PMOs to AD-RDA/CAE. The PAE MDS Working Group has captured ~80% of that combined portfolio and is running a 90-day stand-up behind a Unified IT Systems Migration Plan. DHACA and DHA R&D continue as direct reports. PAE MDS still has no named Acting lead · leadership assignment remains a Key Next Step.
