Orange County's Defense and Aerospace Corridor
Orange County sits at the center of one of the most significant defense and aerospace industrial corridors in the United States, stretching from Los Angeles through OC and into San Diego. The region has historically hosted major defense operations including Boeing's long-running presence in Huntington Beach — which for decades was the site of significant aerospace engineering and manufacturing work — along with operations from Raytheon Technologies (now RTX), L3Harris, and a substantial ecosystem of subcontractors, component manufacturers, and defense-focused engineering services firms serving the primes.
The OC defense sector is not monolithic. It encompasses aerospace systems integration, electronics and avionics manufacturing, defense software and cybersecurity, unmanned systems, and space-adjacent technology development. This variety means buyer profiles, valuation methodologies, and deal structures differ significantly depending on where in the defense ecosystem a company operates. A cleared engineering services firm that provides augmented staffing to prime contractors is valued on different terms than a company with proprietary radar subsystem technology protected by patents and classified program experience.
What unifies the sector from an M&A perspective is complexity. Defense transactions involve government consent processes, regulatory compliance verification, national security review considerations, and workforce dynamics — particularly around cleared personnel — that make these deals longer and more expensive to close than comparably sized commercial transactions. Companies that begin preparing their exit structure early, with a clear understanding of how these factors will be evaluated by buyers, consistently achieve better outcomes than those that enter a process unprepared.
Government Contracts: The Core Valuation Asset and Primary Risk
In a defense company transaction, the contract backlog is the primary asset. Buyers evaluate backlog through several lenses: the ratio of cost-plus contracts (lower risk, lower margin, more predictable) to fixed-price contracts (higher risk, higher margin potential), the remaining period of performance, the agency and program relationships underlying each contract, and the company's historical recompete win rate. A business with a strong book of multi-year cost-plus contracts and a demonstrated track record of winning recompetes commands a materially different valuation than one with a large near-term backlog of single-award fixed-price work nearing completion.
Government contracts are not assignable without the contracting agency's consent. This means every defense M&A transaction must manage the novation process — the formal mechanism by which the government recognizes the acquiring entity as the successor in interest. Novation takes time, requires documentation, and must be factored into deal timelines and working capital agreements. Buyers familiar with defense M&A will price novation risk; sellers who have not considered it will be surprised by the deal structure their buyer proposes.
Additional contract-level considerations include organizational conflict of interest (OCI) provisions, which can restrict what an acquiring entity can bid on post-close, and small business set-aside eligibility, which a target company may lose upon acquisition by a larger buyer. These factors can affect post-close revenue and must be modeled as part of the valuation case.
ITAR, Security Clearances, and Deal Structure Complexity
The International Traffic in Arms Regulations govern the export and transfer of defense articles, technical data, and related services. Companies registered with the Directorate of Defense Trade Controls (DDTC) must manage ITAR compliance continuously and must consider how a change of ownership affects their compliance posture. A buyer that is foreign-owned, foreign-controlled, or foreign-influenced — even indirectly through investors — may trigger a mandatory review by the Committee on Foreign Investment in the United States (CFIUS). CFIUS review can extend deal timelines significantly and, in some cases, result in mitigation agreements that restrict the acquirer's access to certain assets or personnel.
Even in domestic acquisitions, ITAR creates due diligence obligations. Technical data shared during the due diligence process may itself be ITAR-controlled, requiring the parties to establish appropriate access controls and data room protocols before diligence begins. Historical ITAR non-compliance — voluntary disclosures, consent agreements, or unresolved violations — is a material issue that buyers will price into their offers or use to restructure deal terms.
Security clearances at the facility and personnel level add a further dimension. Defense contractors that hold facility clearances (FCLs) through the Defense Counterintelligence and Security Agency (DCSA) must work with DCSA to manage the change-of-control process. Personnel clearances are held by individuals, not companies, but the composition of a company's cleared workforce — and the potential for key cleared personnel to depart in a transaction — is evaluated by buyers as a direct risk to contract performance continuity.
