Sell Your Aerospace Manufacturing Business in 2026: 7x-10x EBITDA, Tier-1 OEM Demand

If you are weighing an aerospace manufacturing sale in 2026, the multiple gap between a certified Tier-1 OEM supplier and a generic precision shop is wider than at any point in the last 15 years. Demand is structural: Boeing, Airbus, Lockheed Martin, RTX, GE Aerospace and Northrop Grumman are all racing to harden a supplier base that contracted by an estimated 20% since 2019. Tier-1s are doubling down on the suppliers who survived and consolidating the rest. This guide covers what buyers actually pay, who is acquiring, and how to position your business for the top of the range when you sell your aerospace manufacturing business.

Why aerospace manufacturing sale multiples are running at a premium in 2026

Two forces are stacking. First, the post-2019 supplier contraction left Tier-1 OEMs structurally short on qualified capacity. Spirit AeroSystems being absorbed back into Boeing in 2025, Howmet (NYSE: HWM) trading at all-time highs, and the public-comp basket of TransDigm (NYSE: TDG), HEICO (NYSE: HEI), Curtiss-Wright (NYSE: CW) and Moog (NYSE: MOG.A) all sitting above 20x EBITDA are the public-market read on the same demand picture. Second, defense spending under the FY2026 NDAA pushed sustained funding into hypersonics, missile defense, unmanned systems and shipbuilding. That money flows through the Tier-2 and Tier-3 supplier base that owner-operators run.

Acquirers are paying up because aerospace customer qualification is the moat. Selling a precision machining business without aerospace certifications gets you 3x-5x. The same shop with AS9100D + Nadcap + active Tier-1 part numbers gets 6x-8x. Add ITAR registration plus a defense mix above 30% and you are at 8x-10x. The certification stack is worth 2-4 turns of EBITDA, and buyers underwrite it explicitly.

Aerospace manufacturing sale multiples: what the 2026 data shows

The table below is the working framework we use when scoping a sell-side opportunity. It is benchmarked against 2024-2026 closed deals in the lower middle market (sub-$25M EBITDA) and reconciled to comparable public-company multiples.

Profile	Certifications	OEM Status	Defense Mix	EBITDA Multiple
Generic precision machining	ISO 9001 only	None / sub-tier	Low (0-10%)	3x-5x
Aerospace-adjacent shop	AS9100D	Tier-3 indirect	Low (10-25%)	5x-6.5x
Qualified Tier-2 supplier	AS9100D + Nadcap	Tier-2 named on prime contract	Medium (25-50%)	6.5x-8x
Direct Tier-1 OEM supplier	AS9100D + Nadcap + ITAR	Tier-1 with LTAs	Medium (40-60%)	8x-10x
Platform-quality OEM partner	Full stack + CMMC 2.0 L2	Sole-source on multiple programs	High (50%+)	10x-12x+

Two adjustments matter inside every band. Customer concentration above 30% with a single OEM compresses multiples by 0.5-1.5 turns even when the customer is investment grade. CMMC 2.0 Level 2 certification is being written into prime contract flow-downs for any supplier touching CUI (controlled unclassified information), and 2026 is the year buyers started treating it as a hard gate rather than a nice-to-have. We cover the full multiples framework on the manufacturing business valuation multiples reference page.

Who buys aerospace manufacturing businesses in 2026: named strategics and PE platforms

Acquirer demand breaks into five distinct archetypes. Knowing which one fits your business changes the offer 1-2 full turns of EBITDA. The full cross-vertical buyer landscape sits in our who buys US manufacturing businesses guide; what follows is the aerospace-specific cut.

Strategic acquirers (Tier-1 OEMs and their consolidators)

The active public-market roll-ups are TransDigm (NYSE: TDG), HEICO (NYSE: HEI), Curtiss-Wright (NYSE: CW), Moog (NYSE: MOG.A), Howmet (NYSE: HWM) and Triumph Group (NYSE: TGI). Boeing, Lockheed Martin, RTX, GE Aerospace, Spirit AeroSystems, Northrop Grumman and Embraer Defense buy direct when they need to vertically integrate a critical capability. UK-listed Senior PLC is active in US aerostructures and fluid systems. These buyers pay the highest absolute dollars and often the highest multiple, but they buy slowly and only when the asset is on-strategy.

Dedicated aerospace PE platforms

AE Industrial Partners, Liberty Hall Capital Partners and Arlington Capital Partners are the three pure-play aerospace and defense funds and they will look at any quality asset above $3M EBITDA. Greenbriar Equity Group, Centerline Capital Partners, Wynnchurch Capital, Ardian and Berkshire Partners are diversified industrial funds with active aerospace and defense platforms. All nine routinely pay 7x-10x for the right Tier-1 supplier.

Generalist industrial PE with aerospace add-on appetite

Roughly 38 of the 76 capital partners we work with have an existing aerospace platform actively hunting add-ons. They underwrite differently from a standalone deal: the comp is the platform multiple, not the standalone multiple, which means an add-on often clears 8x-9x where a standalone would land at 6.5x-7.5x. We map this in detail on our PE firms buying manufacturing in 2026 tracker.

Family offices and independent sponsors

Active for $1M-$5M EBITDA targets where institutional PE will not look. They pay 5x-7x, often with significant rollover, and they are the right buyer for owners who want to stay involved 3-5 years post-close.

International strategics (with CFIUS overhead)

Senior PLC, Safran, Leonardo, Mitsubishi Heavy Industries and other foreign primes will buy US aerospace assets, but ITAR-controlled work plus CFIUS (Committee on Foreign Investment in the United States) review adds 3-6 months and can kill the deal at signing. Worth running if the synergy is real; not worth running blind.

Certifications drive the deal: AS9100, Nadcap, ITAR and CMMC 2.0

This is the part of aerospace M&A that catches generalist sellers off guard. Four certifications are quoted by buyers and underwritten in diligence:

• AS9100D (Rev D, IAQG): The aerospace quality management standard. Without it, you are not a real aerospace supplier. The transfer is name-on-cert, not automatic, so the buyer has to keep your quality system intact for at least one surveillance audit. Worth 1-2 turns of EBITDA on its own.
• Nadcap (PRI/Performance Review Institute): Special-process accreditation (heat treating, NDT, chemical processing, welding, surface enhancement, composites). Each Nadcap process you hold is worth 0.25-0.5 turns and is genuinely hard to replicate. Lapsed or limited-scope Nadcap is a red flag in diligence.
• ITAR (22 CFR 120-130, US State Department DDTC): Mandatory for any defense-end-use work. Registration must be current at signing and a Technology Control Plan must exist. DDTC notification at change-of-control adds 3-8 weeks to close. ITAR is worth 1-2 turns when paired with active defense programs.
• CMMC 2.0 (DoD, Cybersecurity Maturity Model Certification): The DoD final rule (32 CFR Part 170) took effect in 2025 and CMMC requirements began appearing in DoD contracts in 2026. Any supplier touching CUI needs Level 2 (NIST SP 800-171 aligned, third-party assessed). Buyers in 2026 are starting to treat CMMC 2.0 Level 2 readiness as a hard gate, not a nice-to-have, because a non-compliant supplier loses the contract at the next option year.

The certification stack compounds. AS9100D alone is table stakes. AS9100D + Nadcap is a real moat. AS9100D + Nadcap + ITAR + CMMC 2.0 Level 2 is the platform-quality threshold, and that is where the 10x-12x multiples sit.

How to position your aerospace manufacturing sale: OEM mix, DoD status, LTAs

Buyers read three things in your customer roster before they look at EBITDA: which OEMs, which programs and which tier. The hierarchy that matters:

• Tier-1 direct on a named platform (e.g., direct to Lockheed Martin on F-35, direct to Boeing on 737 MAX, direct to RTX on PW1000G): top of the multiple range.
• Tier-2 named on a prime contract (sub to Spirit AeroSystems on 787, sub to Triumph on V-22): solid middle of the range.
• Tier-3 indirect (selling to a Tier-1 supplier who sells to the prime): bottom of the range and the easiest position for an acquirer to bypass.

DoD prime / sub status is a separate axis. Holding a direct DoD prime contract (your CAGE code on a DoD-issued contract) is worth a premium because the cleared status and contracting infrastructure are themselves hard to build. Most owner-operators are subs, not primes, and that is fine, but the prime status is a clear lever if you have it.

Long-Term Agreements (LTAs) are the third lever. An LTA with a Tier-1 OEM, especially one with 3+ years remaining and clean price-escalation language, is the single piece of paper that moves a multiple. Buyers will read the LTA cover to cover. Auto-renewal language, change-of-control consent requirements, and exclusivity carve-outs all get scrutinized. A well-drafted LTA worth $2M+ annual revenue can move the multiple half a turn by itself. The deeper customer-mix framework lives on the how to value a manufacturing business reference.

Defense vs commercial mix: where the premium actually sits in 2026

2024-2026 inverted the historical pattern. Commercial aerospace (Boeing 737 MAX, Airbus A320neo) used to command the premium because of volume and predictable rate. After the MAX grounding aftermath, 787 production stoppages, and Airbus supply-chain friction, commercial volume became less reliable than defense. The FY2026 NDAA pushed sustained funding into programs like Sentinel ICBM, B-21, Columbia-class submarine, and the Replicator unmanned initiative. Defense suppliers with 50%+ defense mix and exposure to those programs are clearing 8x-10x.

The sweet spot for 2026 is a 50/50 to 60/40 defense/commercial mix. Pure-play defense (90%+) gets discounted slightly for program-life concentration. Pure-play commercial (90%+ commercial) gets discounted for cycle risk. Mixed-portfolio suppliers get the cleanest underwriting and the highest multiples.

The aerospace manufacturing sale process: typical timeline and structure

From go-decision to close, plan on 9-12 months. The aerospace-specific steps that extend the timeline beyond a generic manufacturing sale:

1. Pre-process (1-3 months): Normalize TTM EBITDA, document the certification stack, refresh the customer LTA inventory, pre-clear ITAR registration with export-control counsel, document the CMMC 2.0 posture, scope any environmental exposure (chemical processing, plating, anodizing).
2. Buyer outreach to LOI (2-3 months): Targeted approach to 6-12 right-fit buyers, not a 100-name auction. Aerospace is a small community; auctions leak.
3. Diligence (2-3 months): Quality of earnings, customer interviews (handled carefully), AS9100 and Nadcap audit history review, ITAR compliance audit, customer LTA review, environmental Phase I/II, cybersecurity (CMMC 2.0 gap assessment).
4. Definitive docs and close (1-2 months): Purchase agreement, R&W insurance (now standard above $10M EV), ITAR DDTC notification, AS9100 transition plan.

The full selling a manufacturing company to private equity playbook walks through each stage in detail. The aerospace-specific overlay is mostly about getting ITAR and CMMC 2.0 clean before you start, not after.

Common deal-killers in an aerospace manufacturing sale

The five issues that most frequently kill an aerospace deal at LOI or in diligence:

• Lapsed or limited-scope certification: An expired AS9100 surveillance audit, a Nadcap accreditation in jeopardy, or ITAR registration not currently active. Each one is a 6-12 month fix and buyers will not wait.
• Customer concentration above 50% with weak LTA coverage: Even an investment-grade customer at 60%+ concentration with no LTA gets the buyer to discount or restructure as earnout.
• Environmental exposure on chemical processing: Chrome plating, cadmium plating, hexavalent chrome, and trichloroethylene degreasing are red flags. Phase II ESA findings can blow up the deal economics.
• CMMC 2.0 unprepared: A 2025-2026 entrant on the deal-killer list. Suppliers touching CUI with no documented CMMC 2.0 plan are losing contracts at option years, which the buyer underwrites as cliff risk.
• Founder dependency: A founder-CEO who is the named customer relationship at a Tier-1 OEM is a single point of failure. A second-in-command with named buyer-side relationships fixes it; absence of one compresses 1-2 turns.

Worked example: $5M EBITDA AS9100 + ITAR precision aerospace machining seller in Connecticut

Real composite (details anonymized). Connecticut-based precision aerospace machining shop. TTM EBITDA $5.0M on $24M revenue. AS9100D + Nadcap (heat treat, NDT) + active ITAR registration. Customer mix: 35% Pratt & Whitney (RTX), 28% Sikorsky (Lockheed), 18% Collins Aerospace (RTX), 19% commercial Tier-2. Defense / commercial mix: 55/45. LTAs with Pratt and Sikorsky, 3.5 and 4 years remaining. CMMC 2.0 Level 2 gap assessment complete, remediation 60% done.

Base multiple (Tier-2 named, AS9100D + Nadcap + ITAR, mid-50s defense): 7.5x. Concentration adjustment (top customer at 35%, supported by 4-year LTA): neutral. CMMC 2.0 readiness (in progress, not complete): -0.25x. Worked outcome: 7.25x x $5.0M = $36.25M enterprise value. Strategic premium from an active Tier-1 buyer (Pratt’s parent RTX, or HEICO, or AE Industrial as an add-on to an existing aerospace platform): +0.5-1.0x, taking the negotiated outcome to $38.75M-$41.25M.

The same business with CMMC 2.0 Level 2 fully certified, top-customer concentration below 30%, and a second-in-command in place would clear $45M+. The 12-month preparation gap was worth $5M-$8M of enterprise value.

How CT Acquisitions helps when you sell your aerospace manufacturing business

We are a buy-side partner, not a sell-side broker. The mechanics: our 76+ capital partners (38 with active manufacturing platforms, 3 dedicated aerospace and defense funds) pay us when a deal closes. You pay nothing. No retainer. No exclusivity. No 12-month contract. You can walk at any point with no fee.

The aerospace-specific value: we already know which of the 76 funds has an aerospace platform actively hunting add-ons, which Tier-1 OEM consolidator is funded and looking, and which buyer has cleared CFIUS quickly in a comparable deal. That intelligence shortens the buyer search from 6-12 weeks to a single conversation and shortens the whole process from 9-12 months to 60-120 days from intro to LOI. See the full operating model on the capital partners page.

Sell your aerospace manufacturing business: frequently asked questions

What is my aerospace manufacturing business worth in 2026?

AS9100D-certified Tier-2 to Tier-1 aerospace suppliers trade at 7x-10x EBITDA in 2026. Generic precision machining shops without aerospace certifications land at 3x-5x. Platform-quality assets with AS9100D + Nadcap + ITAR + CMMC 2.0 Level 2 and sole-source positions on multiple programs can clear 10x-12x.

Who buys aerospace manufacturing businesses?

Five buyer types. Strategic acquirers (TransDigm, HEICO, Curtiss-Wright, Moog, Howmet, Triumph Group, Senior PLC, Boeing, Lockheed Martin, RTX, GE Aerospace, Spirit AeroSystems, Northrop Grumman, Embraer Defense). Dedicated aerospace PE platforms (AE Industrial, Liberty Hall, Arlington Capital). Diversified industrial PE with aerospace platforms (Greenbriar, Centerline, Wynnchurch, Ardian, Berkshire). Family offices and independent sponsors at the lower end. International strategics for cross-border deals subject to CFIUS.

How important are AS9100 and Nadcap for premium multiples?

They are the difference between a 3x-5x generic machining multiple and a 7x-10x aerospace supplier multiple. AS9100D on its own is worth 1-2 turns of EBITDA. Each Nadcap special-process accreditation you hold adds 0.25-0.5 turns. The certifications take 18-36 months to build organically, which is why acquirers pay up rather than try to replicate them.

How does ITAR affect an aerospace manufacturing sale?

ITAR-controlled defense work requires DDTC (State Department) notification and consent at change of control. The process adds 3-8 weeks to close. Owners with current registration, a documented Technology Control Plan, and no compliance findings transfer cleanly. Lapsed registration or open compliance issues are deal-killers. A pre-process ITAR audit by export-control counsel is essential.

How does CMMC 2.0 affect a 2026 aerospace sale?

CMMC 2.0 became a hard gate in 2026 for any supplier touching CUI (controlled unclassified information). Buyers underwrite Level 2 readiness explicitly because non-compliant suppliers lose DoD contracts at the next option year. If you do not yet have a CMMC 2.0 Level 2 gap assessment and remediation plan, expect 0.25-0.5 turns of multiple compression and a longer earnout.

What about customer concentration with Boeing, Lockheed, or RTX?

Even with investment-grade Tier-1 customers, concentration above 30% compresses multiples 0.5-1.5 turns or pushes the deal into earnout. Buyers underwrite program-life risk regardless of customer credit quality. The 12-18 month fix is additional Tier-1 OEM qualifications, multi-program exposure within existing customers, and intentional new-customer development.

How long does an aerospace manufacturing sale take?

9-12 months from prep-complete to close for a $5M+ EBITDA aerospace business. Slightly longer than generic manufacturing because of ITAR review, FAA / quality audits, CMMC 2.0 gap closure, customer LTA validation, and environmental diligence on chemical processing. Add 12-24 months for proper preparation if certifications, customer LTAs, CMMC 2.0 posture, and environmental are not already current and clean.

How is CT Acquisitions different from a sell-side broker?

We are a buy-side partner, not a sell-side broker. Sell-side brokers represent you and charge 8-12% of the deal plus monthly retainers and require 12-month exclusivity. We work directly with 76+ capital partners including AE Industrial, Liberty Hall, Arlington Capital, Greenbriar, Centerline, Wynnchurch, Ardian and Berkshire. Our 38 manufacturing-focused funds and 3 dedicated aerospace specialists pay us when a deal closes. You pay nothing. No retainer, no exclusivity, no contract. We move faster (60-120 days from intro to LOI) because we already know who the right buyer is. Book a 15-minute call or run the free valuation to start.
