Fixed-Price by Default: The EO 14402 Implementing Guidance Is Now in Effect

Executive Order 14402, Promoting Efficiency, Accountability, and Performance in Federal Contracting, was signed 30 April 2026. It establishes that fixed-price contracts with performance-based considerations should serve as the default and preferred method of procurement. As of mid-July the implementing machinery is in place.

The implementation sequence

The FAR Council updated the Revolutionary FAR Overhaul model deviation text for FAR Part 16, with corresponding updates to Part 52. On 1 July 2026 the Council published guidance implementing E.O. 14402 on acquisition.gov, with the revised Part 16 language taking effect 15 July 2026. On that same date the Department of War issued Class Deviation 2026-O0045, Revision 1, to FAR 16 and DFARS 215, effective immediately, providing direction on submission and approval of justifications for other-than-fixed-price contracts.

Why it matters for cost and pricing work

The justification requirement is the operative change. Choosing a cost-reimbursement or other-than-fixed-price vehicle now carries a documentation burden approved at the agency head level, with dollar thresholds set separately for the Department of War, NASA, DHS, and all other agencies. It is not limited to new work. Contracts and orders already issued that had at least 18 months of remaining performance as of 15 July 2026 also require an approved justification, with a deadline of 15 July 2027. For new solicitations, justifications must be approved before release. Separately, the order directs each agency head to review the agency's ten largest non-fixed-price contracts by value and seek to modify, restructure, or renegotiate them where practicable.

Substantively, a fixed-price default moves risk analysis earlier in the acquisition. Cost realism analysis, which does most of its work in cost-reimbursement source selections, gives ground to price reasonableness. The harder question is how much technical and schedule uncertainty a firm-fixed-price structure can absorb before the contractor prices in contingency that the government pays for regardless. Programs with immature requirements or unstable interfaces are where that tension surfaces first, and they are the ones worth modeling carefully before a structure is locked in.
