The fundamentals underlying the commercial aerospace aftermarket have never been stronger with global air travel demand at record levels and climbing. To meet this demand, operators are keeping aircraft in service longer—a trend compounded by nearly a decade of new delivery shortfalls and ongoing reliability issues with latest-generation engines.

The result is an aftermarket supercycle with structural staying power, and the companies that provide aftermarket parts, repairs, and services are currently among the most sought-after assets in aerospace M&A.

Below, our Aerospace, Defense & Government Services Group highlights what’s fueling M&A momentum across the aero aftermarket and how our recent clients—Aero 3, Jet Parts Engineering, and Victor Sierra Aviation—demonstrate the opportunity.

A Heightened Need

Fleet operators are managing older fleets on longer service cycles. The demand for reliable aftermarket parts, repairs, and services is rising accordingly.

“The aftermarket companies succeeding today have earned the trust of their customers by delivering dependable quality and turnaround times at scale,” says Chris Smith, a managing director. “The best companies have also built cost-effective solutions that give operators a reliable alternative that’s often meaningfully less expensive than going back to the OEM.”

Sponsors, strategics, and infrastructure funds are all active in the space, but strategics have recently been among the most aggressive acquirers. “Strategics recognize that a wider capability set translates directly into deeper customer relationships and a larger share of wallet,” says Mike Rohman, a managing director. “They’re aggressively pursuing the best assets, and that competition is driving real urgency in the M&A market.”

Across the aftermarket, buyer interest is concentrated on segments with the potential to drive above-industry growth and strong margins, including complex component repair and OEM-alternative solutions. “The most sought-after assets share a common profile: scaled platforms with large, attractive repair and parts portfolios, high-quality data that can be leveraged to develop new solutions, and diversified customer relationships that provide growth runway,” says David Jones, a director. “Aero 3, Jet Parts Engineering, and Victor Sierra Aviation all exemplify that profile.”

Component Repair: Aero 3

Harris Williams advised Aero 3, a portfolio company of GenNx360 Capital Partners, on its sale to VSE Corporation. Aero 3 is a scaled, global MRO platform specializing in wheel and brake services, operating across repair, OEM-aligned distribution, and proprietary solutions.

“Aero 3 has a reputation for technical expertise and reliability with OEMs throughout the industry,” says Smith. “As a unique scaled platform within the aviation wheel and brake aftermarket, Aero 3’s footprint and OEM-aligned model enable them to serve as a one-stop shop for fleet operators.”

VSE’s acquisition of Aero 3 broadens its MRO, distribution, and proprietary product offerings as well as its global reach. “VSE acquired facilities as well as a set of capabilities, authorizations, and embedded relationships built over many years,” adds Rohman. “Aftermarket businesses with Aero 3’s profile—highly regulated, non-deferable services, strong OEM alignment, and a scaled footprint—will continue to attract serious buyer interest.”

OEM-Alternative Solutions: Jet Parts Engineering and Victor Sierra Aviation

Harris Williams also advised Jet Parts Engineering and Victor Sierra Aviation Holdings, portfolio companies of Vance Street Capital, on their sale to TransDigm. Together, the platforms deliver OEM-alternative parts and repair solutions, collectively serving the commercial, cargo, general, business, and military aviation end markets.

“Jet Parts and Victor Sierra have built a deep Parts Manufacturer Approval (PMA) parts and Designated Engineering Representative (DER) repair portfolio supported by a skilled engineering and certification team,” notes Smith. “They offer immense value to their customers that only compounds over time.”

“Investors will continue to focus on businesses that either have established PMA and DER portfolios or the foundational data and technical capabilities to build one,” adds Jones. “Engineering expertise, repair data, and customer insights are enduring assets. There’s real value to unlock for companies and investors who can harness them.”

What’s Next

Investor interest in the aero aftermarket has never been broader. Despite a finite supply of scaled, best-in-class platforms, M&A activity shows no signs of moderating.

The opportunity is not limited to scaled platforms. The aero aftermarket remains highly fragmented, and investors who find a strong cornerstone platform and execute a disciplined acquisition strategy are well-positioned to build sought-after businesses.

“The investors who will prevail in this space are the ones who have developed a clear thesis, identified the right platforms, and are prepared to move with conviction,” says Smith. “The fundamentals are compelling, the buyer universe is deep, and the best opportunities will be highly coveted.”
