StandardAero, Inc. (NYSE: SARO): Deep Dive

Industrials | Aerospace engine aftermarket services | Report date: 10 October 2026

Reporting-period check. StandardAero's fiscal year ends 31 December and it reports quarterly. Q3 2026 (quarter ended 30 September) would normally be released in early-to-mid November 2026; Q3 2025 came out on 10 November 2025. So Q3 2026 is not yet due. The most recent period is Q2 2026, expected in early August, and it was released on 6 August 2026 with a call the same day. The six results events used in this report are: Q1 2025 (12 May 2025), Q2 2025 (13 August 2025), Q3 2025 (10 November 2025), Q4/FY2025 (25 February 2026), Q1 2026 (7 May 2026) and Q2 2026 (6 August 2026).

1. What the Company Does

StandardAero takes apart jet and turboprop engines, fixes or replaces the worn parts, puts them back together, runs them in a test cell and returns them to the operator. Engines are the most expensive and most heavily regulated part of an aircraft. Every few thousand flight hours or cycles, an engine has to come off the wing for a "shop visit" that can cost from a few hundred thousand dollars to several million. Airlines, militaries, business-jet owners, lessors and even the engine makers themselves pay StandardAero to do that work. It does not make engines. It is the largest independent shop that keeps them flying, with roughly 8,000 employees in 12 countries, according to the FY2025 10-K.

History. According to the Manitoba Historical Society, the business began in Winnipeg in 1911 as Standard Machine Works, founded by Charles Pearce and William Bickell to repair engines for automobiles, trucks and tractors. It moved into aircraft engines in the 1920s and was incorporated as Standard Aero Engine Limited in 1949. That Canadian, bush-plane origin still shows: Winnipeg is one of the company's two or three most important sites, and turboprops, the engines on regional and utility aircraft, remain a core competence.

For most of its modern life the company has been passed between owners, and each ownership period changed what it is:

• Conglomerate years (1989-2004). Ownership moved from Hawker Siddeley to BTR, then into Dunlop Standard Aerospace, which Doughty Hanson formed in 1998.
• First Carlyle ownership (2004-2007) and Dubai Aerospace Enterprise (2007-2015). DAE bought it together with Landmark Aviation.
• Veritas Capital (2015-2019). Under Veritas, StandardAero bought Vector Aerospace from Airbus in 2017. That deal added helicopter and military engine work and a large component repair network.
• Second Carlyle ownership (2019 onward). Under Carlyle it bought Signature Aviation's Engine Repair and Overhaul business in 2021, which deepened business-jet engine coverage, and Aero Turbine in August 2024, which added component repair. It listed on the NYSE on 2 October 2024 at $24 a share. The holding entity, Dynasty Parent Co., renamed itself StandardAero, Inc. that September (FY2025 10-K).

Two strategic shifts under Russell Ford, CEO from October 2013 to 30 September 2026, define the business today:

1. From legacy engines to new-generation engines. The company spent heavily to become an authorized shop for the CFM LEAP, the engine on the Airbus A320neo and Boeing 737 MAX families. It is among the first independent "Premier MRO" licensees in the Americas, and it built a dedicated CFM56 "Center of Excellence" in Dallas-Fort Worth to capture the peak overhaul years of the outgoing engine generation.
2. Toward doing more repair in-house. It has moved more component repair inside, through Aero Turbine, the 2026 purchase of Unified Turbines and in-house repair engineering. More of each shop visit's value now stays with the company instead of going to outside part suppliers.

The problem it solves. An engine overhaul combines regulated engineering, scarce skilled labour, expensive test infrastructure and access to OEM technical data and parts. Most operators cannot justify that investment for their own fleet. The engine makers (GE, CFM, Rolls-Royce, Pratt & Whitney Canada, Honeywell, Safran) run their own service networks but cannot or will not cover every engine type, region or customer. StandardAero fills those gaps. For a regional airline it is the overhaul shop. For an engine maker it is often a licensed subcontractor that does the OEM's own aftermarket work. For a lessor it is the shop that brings an engine back to a value-holding condition between leases.

Why it is hard. Four things are hard to copy: OEM licences and technical data, regulatory approvals (FAA, EASA, Transport Canada) for every repair, test cells calibrated for each engine type, and a workforce that has done thousands of shop visits on that engine. The detail is in Section 3.

A concrete example. A Caribbean low-cost carrier flying 737 MAX aircraft (Arajet signed with StandardAero in July 2026) removes a LEAP-1B engine when its exhaust-gas-temperature margin runs thin. The engine goes to San Antonio. Technicians induct it, strip it into modules, and inspect and measure each blade, vane, disk and case against CFM's limits. Parts within limits are cleaned and reused. Repairable parts go to the company's component repair shops, which have developed more than 475 LEAP repairs. Life-limited parts at the end of their certified life are replaced with new or used-serviceable material. The engine is rebuilt, run in a test cell to prove thrust and temperature margins, and shipped back with release documentation. While it is away, the airline can lease a spare from StandardAero's pool. The contract can also bundle quick-turn visits, component repairs and engine-health data analysis.

2. Business Segments

StandardAero reports two segments. Customers think of it mainly through three end markets, which cut across both segments: commercial aerospace, business aviation, and military and helicopter.

2.1 Engine Services (~88% of FY2025 segment revenue)

What it does. This is the full shop visit: maintenance, repair and overhaul of whole engines, plus on-wing and field service, engine leasing and exchange, asset management (buying and trading used engines and parts) and engineering. Customers are airlines and regional carriers, lessors, business-jet owners and their management companies, militaries, and OEMs that subcontract their own aftermarket work. Engine coverage is broad:

• Commercial: LEAP-1A/-1B, CFM56-7B, the GE CF34 family on regional jets, Pratt & Whitney Canada turboprops, Rolls-Royce RB211-535 and AE 3007.
• Business aviation: Honeywell HTF7000 and other mid-size and super-mid-size jet engines.
• Military: Rolls-Royce AE 1107 (V-22) and AE 2100 (C-130J), T56/J85 legacy types, and work on the F110 and F100.
• Helicopters: Safran Arriel and other rotorcraft engines.

Core capability. The ability to run very different engine programmes through high-volume, repeatable lines, combined with the OEM licences that make that legal. Almost nobody else covers business jets, regional jets, narrowbodies, turboprops, helicopters and military transports under one roof.

Role in the group. This is the volume business and the growth bet. LEAP and CFM56 DFW sit here, so the 2025-2026 margin dip and recovery from those ramps happened here. Engine Services margins are structurally lower than component repair because a large share of the price is parts the company buys and passes through. The 2026 contract restructuring that removes low-margin pass-through material (Section 3) mainly affects this segment.

Main rivals: OEM service networks (GE Aerospace, Safran/CFM, Rolls-Royce, Pratt & Whitney), airline-owned shops (Lufthansa Technik, Delta TechOps, AFI KLM E&M), MTU Maintenance, ST Engineering and FTAI Aviation.

2.2 Component Repair Services (~12% of FY2025 segment revenue)

What it does. Repairs individual engine parts and accessories (blades, vanes, combustors, cases, fuel and airflow components) rather than whole engines. It serves commercial aerospace, military, land and marine gas turbines, and other industrial users. A meaningful share of its work comes from Engine Services. The rest is for third-party shops and operators.

Core capability. Developing and certifying repairs. The company holds an FAA Organization Designation Authorization, Transport Canada design approval and FAA Designated Engineering Representative status (FY2025 10-K). Together these let it engineer a repair, prove it to the regulator and use it without waiting for the OEM. Every time CRS repairs a part instead of buying a new one, the shop visit gets cheaper for the customer and more profitable for the company. In a market starved of castings and forgings, it is also faster.

Why it is separate. Different economics (labour and engineering-heavy, with little pass-through material), different customers (it sells externally too) and different history (much of it came from the Vector and Aero Turbine acquisitions).

Role in the group. The margin engine and the strategic lever. Management describes CRS as both a profit centre and a way to protect Engine Services from parts shortages. The 2024 Aero Turbine and 2026 Unified Turbines deals, the second adding hot-section repairs on Pratt & Whitney and Honeywell turboprops, were both bought to pull more repair in-house. Mix shifted towards CRS in 2025, when it grew faster than Engine Services. In Q2 2026 it grew faster again but at weaker margins, for reasons covered in Section 8.

Main rivals: Chromalloy (private), OEM repair divisions, the repair arms of MTU and Lufthansa Technik, and many specialist repair houses.

End-market mix

Across both segments, FY2025 revenue was roughly 59% commercial aerospace, 19% business aviation, 18% military and helicopter, and 3-4% other, mostly land and marine. Military and helicopter (17.8%) is disclosed in the 10-K. The other shares are derived from FY2024 end-market revenue and FY2025 reported growth rates. Military's share has edged down because commercial grew faster. Management stresses that the roughly 40% outside commercial airlines is the part least exposed to jet-fuel shocks.

Geographic mix

By customer location in FY2025 (10-K):

The company is mainly a North American business: the US and Canada were about 68% of FY2025 revenue (70% in FY2024). The Canadian weight reflects its Winnipeg roots and large Canadian sites, not only Canadian customers. The UK share fell sharply in 2025, from about 11.5% to 7%, while Asia's share almost doubled from about 4.5% to 8%. Customer location also moves with where lessors and OEM customers book work, so one year's swing should not be read as a structural trend. The operating footprint is broader than the revenue map: sites in the US, Canada, the UK, France, Ireland, the Netherlands, Romania, Singapore, Australia, South Africa, Brazil and Kenya, many inherited with the helicopter and component businesses from Vector.

3. Products and Operations

The engine programmes that matter

Each of StandardAero's businesses is really an engine programme with its own lifecycle, licence and customers. The ones that matter to the investment case:

CF34 (regional jets). This GE engine powers the Embraer E-Jet/E175 and Bombardier/MHIRJ CRJ families. It has been the company's main growth engine of the past two years. Management attributes this to the fleet's age profile: large numbers of CF34-8 engines are entering their heaviest overhaul windows at the same time, and US regional airlines cannot replace aircraft quickly. CF34 demand outgrew Winnipeg so fast that it spilled into the company's military facilities (Q1 2026 call). The work centres on Winnipeg, which completed a 70,000 sq ft expansion in September 2026. The Manitoba government supported it with a C$3 million grant, and the expansion added nearly 40% to the site.

CFM56-7B (Boeing 737NG). The previous generation's narrowbody workhorse, now at or near its peak overhaul years. StandardAero built a CFM56 Center of Excellence at Dallas-Fort Worth. It inducted its first full performance restoration there in Q2 2025, added engine exchange and lease offerings, signed a three-year award with a major North American airline (Q3 2025), and reached profitability in Q2 2026.

LEAP-1A / LEAP-1B (A320neo and 737 MAX). The long-term bet. As one of CFM's Premier MRO licensees, StandardAero gets OEM technical data and support to do full overhauls on an engine CFM is building by the thousand. The ramp so far:

• 10 inductions in 2024 and 60 in 2025.
• More than 70 cumulative by Q1 2026, about a dozen of them full performance restorations.
• First full LEAP-1A overhaul completed in early 2026.
• Over 475 component repairs developed.
• Profitability reached in Q2 2026.
• Customers named in 2025-2026 include Arajet, SunExpress (the Turkish Airlines-Lufthansa joint venture), lessor Avolon (a "LeaseTEAM" multi-year agreement) and AviLease. Most LEAP work is done in San Antonio.

Today most LEAP visits are lighter workscopes that management calls CTEMs, not full performance restorations (PRSVs). Management expects that mix to persist for "the next 2 to 3 years" (Q1 2026 call). Revenue per visit rises sharply once the fleet needs heavy shop visits.

HTF7000 (super-mid-size business jets). This Honeywell engine powers the Challenger 300/350, Gulfstream G280, Embraer Praetor and Cessna Citation Longitude. StandardAero holds an exclusive worldwide heavy-maintenance licence from Honeywell for it (Q1 2026 call), backed by an expanded facility in Augusta, Georgia, which was full almost as soon as it opened (Q3 2025 call). This is the best example of the "OEM-directed exclusive" model described in Section 4.

Rolls-Royce military family (AE 1107, AE 2100) and RB211/AE 3007. In Q1 2026 Rolls-Royce awarded StandardAero about 80% of all OEM-directed MRO work on the AE 1107 (V-22 Osprey) and AE 2100 (C-130J) worldwide, under multi-year agreements running "well into the next decade". The commercial RB211-535 (Boeing 757) and AE 3007 (Embraer ERJ-145, Citation X) are mature Rolls-Royce licences.

Turboprops and helicopters. Pratt & Whitney Canada turboprops (PT6A, PW100) and Safran's Arriel are long-tail businesses: many operators, small fleets, steady work. Unified Turbines, which had been a StandardAero supplier since 2001, was bought to bring hot-section repairs on these engines in-house.

How a shop visit works

The operating model is a sequence of steps, each with its own constraint:

1. Induction and teardown. The engine arrives with its records and is disassembled to module and then piece-part level. The constraint is hangar floor space and certified technicians.
2. Inspection and disposition. Each part is measured against the OEM manual and sorted into serviceable, repairable or scrap. Engineering judgement here decides how much of the visit's cost is parts versus labour.
3. Component repair (CRS). Repairable parts are routed in-house or to external vendors. In-house routing is faster and keeps margin. The constraint is repair approvals and skilled craft labour, which is exactly what limited CRS in Q2 2026.
4. Material procurement. Scrapped parts are replaced with new OEM parts, approved alternatives or used-serviceable material from the company's asset-management trading arm. The constraint is the industry-wide shortage of castings and forgings. Management says StandardAero "aligns your supply chain to the longest lead time item" (CFO Dan Satterfield, Q2 2026 call).
5. Reassembly and test. The engine is rebuilt and run in an engine-specific test cell. Test-cell capacity is lumpy and expensive to add.
6. Release and delivery. Paperwork under FAA, EASA or Transport Canada repair-station rules goes out with the engine. Revenue is largely recognised over the course of the visit, so a visit held up waiting for one part becomes a "contract asset" on the balance sheet until it ships. That is why delayed parts show up as working-capital swings rather than lost revenue.

The pass-through material restructuring matters here. In late 2025 the company renegotiated certain long-term commercial contracts so that material it had been buying and re-billing at little or no margin is removed from its revenue. Management guided to eliminating several hundred million dollars of such revenue in 2026 (Q3 2025 call) and called the effect on profit minimal. The result is a smaller top line and less inventory tied up in low-return material.

Recent capacity and plant events

• Augusta, Georgia (HTF7000): expansion completed in 2025.
• Winnipeg (CF34, CFM56-7B): 70,000 sq ft expansion completed in Q3 2026, with capacity already booked before it opened (Q1 2026 call).
• DFW (CFM56): ramped through 2025 and became profitable in Q2 2026.
• San Antonio (LEAP): ramping, with full-overhaul capability proven in early 2026.
• Phoenix (CRS): a small fire in December 2025 shut the site for about a month, with output expected to normalise gradually through 2026 (Q4 2025 call).
• Component repair capacity: management has moved repair work into the back shops of existing engine facilities to keep up with commercial demand. That added capacity faster than a new building would, at the cost of learning-curve inefficiency (Q2 2026 call).
• Unified Turbines: acquisition closed in Q2 2026.

Training hubs in Winnipeg, San Antonio, Dallas and Van Nuys, plus a new UK apprenticeship scheme, exist because labour is a capacity input as binding as square footage. About 10% of the roughly 8,000 staff are covered by collective agreements, in the UK, Ireland and Australia, or by statutory arrangements in France and the Netherlands (FY2025 10-K).

4. Customers

StandardAero serves about 5,000 customers worldwide, and roughly 80% of FY2025 revenue came from long-term agreements (FY2025 10-K). There are four distinct types of buyer, and they buy for different reasons.

1. Engine OEMs, subcontracting their own aftermarket. Rolls-Royce, Honeywell, Pratt & Whitney Canada and Safran do not want to build their own shop for every engine type and region. They designate StandardAero as their exclusive or semi-exclusive overhaul provider (the "OEM-directed" model). The buyer is the OEM's services or aftermarket organisation. It looks at turn time, quality escapes, capacity commitment and the shop's ability to absorb fleet surges. Sales cycles are measured in years, and contracts run as long as 30 years. The top four OEM customers were 36% of FY2025 revenue, down from 41% in 2024 and 43% in 2023. The 10-K does not name them, but the licence list (Rolls-Royce, Honeywell, Safran, CFM, P&WC) shows who they probably are. One customer, labelled "Customer A" in the 10-Qs, is large enough to be flagged for concentration.

That concentration reflects quality more than fragility: an OEM entrusts its brand on an engine to only a few shops. Its risk is that the OEM writes the rules and can re-insource, change licence terms or appoint more licensees when renewals come up. The share has fallen because LEAP and CFM56 work is sold directly to airlines and lessors, not because OEMs have left.

2. Airlines and regional carriers. The buyer is the airline's powerplant or technical-operations director, with procurement and finance closely involved because engine maintenance is one of an airline's largest cost lines. Criteria: turnaround time (an engine in the shop is a grounded asset or a leased spare), cost per shop visit, workscope engineering (how much of the engine gets rebuilt), quality and spare-engine support. Campaigns typically take 6-18 months and lead to multi-year fleet agreements. These may be time-and-materials, fixed price per event, or (for a limited part of the book) priced per engine flight hour or cycle. Regional carriers on CF34 are the core of this group. LEAP customers such as Arajet and SunExpress are the growth.

3. Lessors and asset managers. Avolon and AviLease buy differently. They care about the engine's residual value and the condition it is returned in, so they want sensible workscopes, documentation that satisfies the next lessee, and flexible green-time and exchange solutions. LeaseTEAM-type agreements give a lessor's airline customers access to pre-agreed StandardAero services.

4. Militaries and governments. Work comes through OEM-directed programmes (such as AE 1107 and AE 2100 via Rolls-Royce) or direct government contracts. Buyers are programme offices that care about readiness and turn time, inside budget cycles. Sales cycles are long and politically timed. The 2025 US government shutdown and the Q2 2026 "input delays", where engines did not arrive when planned, show how timing rather than demand drives this revenue.

Why customers choose StandardAero. Five specific reasons, not generic ones:

• A licence competitors lack: exclusivity on HTF7000, 80% of AE 1107/AE 2100.
• Independence from the OEM. For an airline that wants negotiating leverage over GE or CFM, an independent licensed shop is a check on OEM pricing.
• Breadth across fleets. An operator with turboprops, regional jets and business jets can use one provider.
• In-house repair. Fewer parts bought new means faster turns and lower cost.
• Asset-management support. Spare engines, exchanges and used-serviceable material keep the customer flying while the engine is in the shop.

Switching costs. These are real but uneven:

• OEM-directed work: the OEM would have to re-qualify another shop or build capacity, which takes years. These are the stickiest relationships, protected until the licence comes up for renewal.
• Airline fleet contracts: multi-year terms and the operational pain of moving mid-contract (records, tooling, test-cell correlation) make switching rare. At renewal, though, the work is genuinely contestable, especially on CFM56 and LEAP where several licensed shops compete.
• Lessors: switch most easily, job by job.

Revenue predictability. The 80% long-term-agreement share makes demand predictable. Timing is not: when work arrives depends on engines coming off-wing, and when it ships depends on parts. In a parts-short market, ship dates drive cash flow from quarter to quarter.

5. Competitive Landscape and Moat

Industry structure

Engine MRO has three tiers of competitor, and StandardAero sits in the third.

1. The OEMs (GE Aerospace, CFM/Safran, Rolls-Royce, Pratt & Whitney). They design the engines, control the technical data, sell most new parts and want as much aftermarket as they can capture. On new engines they often sign "power-by-the-hour" service agreements at delivery that lock the work into their own network for years. Over time they have learned that they cannot serve every engine alone, so they license selected outside shops.
2. Airline-affiliated MROs (Lufthansa Technik, Delta TechOps, AFI KLM E&M, and Iberia and IAG's new LEAP shop). They do their parent's work and sell spare capacity to third parties. They are large on narrowbody and widebody engines and small on business jets, helicopters and military.
3. Independents (StandardAero, MTU Maintenance as part of MTU Aero Engines, ST Engineering, and FTAI Aviation's module-swap model). Their value to customers is that they are neither the OEM nor a rival airline.

Market share is set by licences. On a licensed exclusive platform (HTF7000, AE 1107/2100) StandardAero's share is very high. On contested narrowbody engines (CFM56, LEAP) it is one of many shops with a mid-single-digit to low-double-digit share of visits. In the overall engine-MRO market it is a top-ten player. No source I could verify publishes a reliable market-share ranking.

Competitor table

Where StandardAero wins and loses

• Against the OEMs. It wins where the OEM would rather license than build: mature, smaller fleets and business and military engines. There, being the OEM's chosen partner beats competing with it. It loses on early-life new engines, where the OEM's long service agreements capture the work. That is why LEAP growth runs through airlines and lessors that chose not to sign OEM long-term deals. The relationship is a mix of rivalry and partnership, because the same OEMs are also its biggest customers and parts suppliers.
• Against airline-affiliated shops. It wins with customers that do not want a competing airline doing their maintenance, and with breadth beyond narrowbodies. It loses where a carrier's own shop has scale advantages on its home fleet.
• Against MTU Maintenance and ST Engineering. These are the closest like-for-like rivals. StandardAero's edge is North American density, the CF34 and business-aviation franchises, and military exposure. Its gaps are no GTF licence (MTU is strong there) and less Asian scale.
• Against FTAI. FTAI attacks the CFM56 overhaul with module swaps and repaired used parts, a cheaper alternative to a full shop visit for engines near the end of their life. StandardAero's CFM56 strategy at DFW, which bundles quick-turns, green-time leases and exchanges, partly answers that model.

Barriers to entry

High in the places that matter:

• An engine-type licence can take years to win and often depends on OEM goodwill.
• Regulatory approvals are needed for every repair and every station.
• Test cells are engine-specific and expensive.
• The scarcest input is technicians who have done the work before.

A well-funded newcomer could buy a shop, but it could not quickly buy an OEM's trust or a fleet operator's records history. The barrier is lower on open-aftermarket engines like LEAP, where CFM deliberately licenses multiple shops. Iberia and IAG (April 2026) and China's SSAMC (May 2026) joined the LEAP Premier network this year.

Structural shifts

1. OEMs widening licence networks on new engines. This is good for independents' access but bad for exclusivity.
2. A shift in value from labour to parts and repairs. That rewards in-house repair capability, which is why StandardAero is buying CRS businesses.
3. The used-serviceable and module-swap model (FTAI) eating into late-life CFM56 overhauls.
4. Private-equity consolidation of component repair shops.

Moat: Narrow - intangible assets (OEM licences) and regulatory/qualification barriers, plus switching costs on OEM-directed work

The evidence is in the exclusive and semi-exclusive licences on HTF7000, AE 1107/2100, Arriel and RB211, the multi-decade OEM-directed contracts and the regulatory approval stack (Sections 3 and 4). These have held through several ownership changes, and OEMs have expanded rather than withdrawn them, as the 2026 AE 1107/2100 award and license expansion show. The moat is narrow rather than wide because it is borrowed: the licences belong to the OEMs, which are also StandardAero's competitors and suppliers. On the open LEAP and CFM56 aftermarket the company competes on execution against many licensees. The thing most likely to erode it is an OEM declining to renew, or diluting, an exclusive licence on a large platform, or capturing more new-engine aftermarket through service agreements.

6. Industry

What drives demand

Engine MRO demand is roughly the installed fleet times utilisation times the shop-visit frequency each engine type needs. Three forces currently stack in the industry's favour:

1. Air traffic and flight hours have recovered to above pre-pandemic levels. More cycles mean more engine wear.
2. OEM delivery shortfalls. Airbus and Boeing have been unable to deliver aircraft at planned rates for years, so airlines keep older aircraft flying longer. Fewer retirements mean more shop visits on legacy engines such as the CFM56 and CF34. Management said on the Q1 2026 call that retirements "remain very low".
3. New-generation engine durability. LEAP, and especially the GTF, have needed earlier and more frequent shop visits than planned, pulling demand forward and stretching total capacity.

Size and growth

Oliver Wyman's Global Fleet and MRO Market Forecast 2026-2036 puts the global MRO market at about US$140 billion in 2026, with engines about half of it (~US$70 billion), the single largest category. It forecasts the overall market growing about 3.3% a year to 2036. Fleet growth drives that, and new-generation engine shop visits shift engine MRO's mix towards LEAP and GTF over the decade. Other research houses put engine MRO between roughly US$50 billion and US$95 billion depending on scope. The variation is about definitions, not direction.

Supply chain position

The chain runs: raw materials and alloys → castings, forgings and machined parts (Precision Castparts, Howmet and others) → engine OEMs (design, final assembly and new-part sales) → operators. MRO shops sit between the parts supply and the operator. They buy parts from OEMs and suppliers, add engineering and labour, and sell availability to operators. Constraints in the castings and forgings layer now limit the whole industry. Oliver Wyman and ARSA's 2026 assessments describe the supply chain and labour as "throttling" MRO expansion. The constraint sets everyone's turn times and gives shops that can repair rather than replace a structural advantage.

Regulation

Every repair station is certified (FAA Part 145, EASA Part-145, Transport Canada), and every repair must be approved, either in the OEM manual or through an engineering approval such as the FAA DER/ODA system. Regulators do not cap the number of shops, but OEM control of technical data and parts works as a private licensing system on top of public regulation. Policy debates on "right to repair" in aviation and on approved-alternative parts (PMA/DER) shape how much leverage OEMs keep. Military work adds government procurement rules and, for some programmes, export controls.

Cyclicality

Engine MRO is less cyclical than new-aircraft manufacturing but not acyclical. In a downturn, airlines park their oldest aircraft first and cannibalise parked engines for green time, so shop-visit demand can drop sharply for one to two years. 2020 was the extreme case. In upturns, MRO typically lags traffic but then runs hot for years. Shop visits are mandatory once an engine reaches its limits but can be deferred by using green time, so the industry absorbs shocks with a lag. Business-jet MRO follows flight hours and corporate profits. Military MRO follows budgets and operating tempo and is mostly countercyclical to commercial.

Tailwinds and headwinds

Tailwinds:

• An ageing installed fleet with low retirements.
• New-generation engines needing more shop visits than planned.
• Rising defence budgets and operating tempo.
• A business-jet fleet flying more hours.
• OEMs' growing willingness to license independents on open-aftermarket engines.

Headwinds:

• Castings and forgings shortages that stretch turn times and tie up working capital.
• Scarce skilled labour.
• Jet-fuel price spikes, including the 2026 Middle East shock, which squeeze airline cash.
• Module-swap and used-serviceable alternatives that cap pricing on late-life engines.
• The eventual retirement wave that will end the CFM56 and CF34 overhaul peak, likely in the 2030s.

7. Growth Triggers

Ranked by how much each could change the business.

• LEAP volume growing into heavy overhauls. Management targets LEAP becoming a US$1 billion-a-year revenue programme by the end of the decade, rising to "several billion" in the early 2030s as work shifts from light CTEM visits to full performance restorations. The company says it is pursuing more long-term airline and lessor awards. The decade-end target has been repeated on every call since Q2 2025 (Q2 2025, 13 Aug 2025; Q3 2025, 10 Nov 2025; Q4 2025, 25 Feb 2026; Q2 2026, 6 Aug 2026).
• Rolls-Royce AE 1107 and AE 2100 military award. StandardAero will handle about 80% of all OEM-directed MRO on these engines globally (V-22 Osprey and C-130J) under multi-year agreements extending "well into the next decade" (Q1 2026, 7 May 2026). Management guided military growth to be weighted to H2 2026 (Q2 2026, 6 Aug 2026).
• New OEM licence expansion across turbofan and turboprop platforms. A newly signed expansion with an unnamed "key OEM partner" is expected to add EBITDA from 2027 and reach full run-rate in 2029, with about 80% of the benefit in Engine Services. Management says margins will be above the company average (Q2 2026, 6 Aug 2026).
• Winnipeg CF34/CFM56 capacity coming online. The expansion, with capacity booked in advance, completes the CF34 growth plan, which competes with military work for floor space (Q4 2025, 25 Feb 2026; Q1 2026, 7 May 2026; Q2 2026, 6 Aug 2026). It finished in September 2026, so the trigger now is filling it.
• In-sourcing component repair via Unified Turbines. Hot-section repairs on P&W and Honeywell turboprops are expected to reach a "mid-single-digit" percentage EBITDA run-rate after synergies within 18 to 24 months of the May 2026 announcement (Q1 2026, 7 May 2026; Q2 2026, 6 Aug 2026).
• HTF7000 exclusive heavy-maintenance licence on a growing fleet. Honeywell's worldwide exclusive heavy-maintenance ticket and the expanded Augusta site support continued business-aviation growth (Q3 2025, 10 Nov 2025; Q1 2026, 7 May 2026).
• Pass-through restructuring improving cash conversion. Management expects the margin benefit to show in the quarters after the material is gone, with better working capital and free cash flow (Q3 2025, 10 Nov 2025; Q1 2026, 7 May 2026). The mechanism is in Section 3.
• Capital deployment across five channels. New platforms, organic capacity, licence deals, M&A and buybacks, ranked by IRR and ROIC, with leverage kept at 2-3x (Q2 2026, 6 Aug 2026). Paul McElhinney, CEO since 1 October 2026, will present for the first time on the Q3 2026 call.

8. Key Risks

8.1 LEAP economics may not arrive as planned

The main long-term growth bet (Section 7) only works if LEAP engines need heavy overhauls on roughly the schedule management assumes, and if StandardAero wins a fair share of that work.

• Durability improvements could cut demand. CFM is actively improving LEAP durability. Fewer, later heavy visits would push revenue out.
• More competition for the same work. The Premier MRO network is widening (Section 5), and CFM keeps much early-life work under its own service agreements. Both compress what independents can win.
• Thin early margins. The programme only just reached profitability.

Management itself acknowledged the uncertainty:

"For a brand-new engine, we don't know about the long-term durability of the engine and when those light work scopes are going to be shifting to heavy work scopes." - Russell Ford, CEO (Q2 2026 call, 6 Aug 2026)

Calibration: high probability of some timing slippage, moderate impact. This is a drag on the trajectory, not a threat to the core.

8.2 Dependence on OEMs that are also competitors

The OEMs are StandardAero's licensors, biggest customers (36% from the top four) and dominant parts suppliers: the 10-K says its four largest parts suppliers, all OEMs, account for a "substantial majority" of purchases. An OEM can hurt the company in three ways:

• Decline to renew or dilute an exclusive licence.
• Reprice or ration parts.
• Steer new-engine aftermarket into its own network.

Most licences have long tails, so any single event would phase in over years. But the 2026 licence expansion shows the reverse is also true: one negotiation can move several years of earnings. Calibration: low probability in any given year, high impact if a top licence is lost.

8.3 Parts shortages turning into working-capital and cash-flow swings

Because revenue is recognised as work progresses, an engine stuck waiting for a forging sits as a contract asset (Section 3).

• Track record so far. Contract assets swelled through 2025, and 2025 free cash flow depended on a strong Q4 when held-up engines finally shipped. Q1 2026 was a cash outflow. Q2 2026 was positive, and management credited supply-chain initiatives.
• What makes it worse. A worsening castings shortage, or a supplier failure on a high-volume part, would delay deliveries and cash without necessarily cutting demand.

Calibration: high probability of continued lumpiness, moderate impact. This is the most likely reason a quarter disappoints.

8.4 Labour and execution in component repair

CRS margins fell in Q2 2026 for three reasons: moving work into existing back shops, the cost of ramping new hires, and mix. The December 2025 Phoenix fire showed the extra exposure of single-site repair processes. CRS is meant to be the margin engine and the shield against supply shortages, so if it cannot hire, train and keep technicians fast enough, both roles weaken. Calibration: moderate probability, moderate impact. Management describes it as temporary, but labour scarcity is industry-wide.

8.5 A commercial aviation shock reaching the shop floor

The 2026 Middle East conflict pushed jet fuel sharply higher. Management says there has been no effect on demand and that commercial MRO is almost entirely non-discretionary:

"Nearly 40% of our business sits in end markets that are not sensitive to jet fuel prices." - Russell Ford, CEO (Q2 2026 call, 6 Aug 2026)

That is partly protection and partly a reminder that the other 60% is exposed. A prolonged fuel shock or recession would hit through the channel described in Section 6: airlines parking older aircraft (the CF34 and CFM56 fleets StandardAero is most exposed to) and running engines on green time. Management notes the lag is "years, not quarters", which spreads the damage rather than avoiding it. Calibration: low-to-moderate probability, high impact if it happens.

8.6 Ownership overhang and a leadership transition happening at the same time

Carlyle has sold steadily since the IPO (Section 10) and still holds about a quarter of the shares, with board-designation rights tied to that stake. Further secondary offerings are likely, and the company has partly used buybacks to absorb them.

At the same time:

• The long-time CEO has left. Russell Ford led the company for 13 years and steps down as executive chairman at year-end.
• The new CEO comes from the board. Paul McElhinney, previously the lead independent director, became CEO on 1 October 2026 and becomes chairman on 1 January 2027.

A new CEO often resets guidance, priorities or accounting judgements, which can make the business harder to read for several quarters. Calibration: high probability of some disruption, low-to-moderate business impact.

8.7 Military revenue depends on when engines arrive

Military and helicopter growth guidance was raised in May 2026, then the segment declined in Q2 because of "input delays" on certain platforms, with growth pushed into the second half. Government shutdowns (2025), budget continuing resolutions and fleet-readiness decisions decide when engines arrive, and StandardAero cannot control that. Calibration: moderate probability of more slippage, low long-term impact given the multi-year awards.

9. Walk the Talk

Concalls used: Q1 2025 (12 May 2025), Q2 2025 (13 Aug 2025), Q3 2025 (10 Nov 2025), Q4/FY2025 (25 Feb 2026), Q1 2026 (7 May 2026), Q2 2026 (6 Aug 2026). The most recent is within 90 days of today.

The one that came due: LEAP and DFW profitability. In mid-2025 management said its two ramp programmes would turn profitable "late this year or early next year". The window then moved to "early 2026", then "first half of 2026". In August 2026 management could say:

"We achieved profitability in the second quarter while continuing to ramp the program and win new awards." - Russell Ford, CEO (Q2 2026 call, 6 Aug 2026)

The direction never changed and the target was hit inside the last-stated window. But each restatement moved it later, a pattern to remember when reading the decade-end LEAP target.

The quiet reversal: military. In May 2026 management raised military and helicopter growth from high single digits to low double digits, citing higher operating tempo and defence spending. Ninety days later the segment had shrunk year on year, and the explanation was engines arriving late on certain platforms, not weaker demand. The full-year raise was not formally withdrawn; growth was simply described as weighted to the second half. This is the clearest case of guidance getting ahead of what the company controls.

The accurate call: cash. In 2025 management repeatedly told investors that delayed engines would ship in the fourth quarter and bring cash with them, raised its free cash flow range twice on that basis, and then beat the top of it. When a parts-constrained shop can say which quarter its stuck engines will clear, it has real visibility into its own supply chain.

Assessment. On what it controls (capacity projects, programme break-evens, cash timing, contract restructuring), this management team does what it says, usually a little late and sometimes a little better than promised. Guidance on full-year results has been conservative: every 2025 range was raised and then beaten, and 2026 has been raised twice so far. Where it is optimistic is on outcomes others control: military engine arrivals and the timing of LEAP's heavy-visit wave. The leadership change means the people who made these calls will not all be the ones accountable for the next six quarters.

10. Ownership, Governance and Shareholder Friendliness

Part 1 - Ownership and control. StandardAero is a post-IPO company that its private-equity owner is gradually selling down. Carlyle owned ~25.5% and GIC ~5.8% at 30 June 2026 (Q2 2026 10-Q). Their combined stake fell from about 56% at the end of 2025 (Carlyle 45.6%, GIC 10.3%, FY2025 10-K) through:

• a 57.5 million-share secondary offering at $31 in January 2026, and
• further Carlyle reductions to 25.4% by 31 March 2026 (Schedule 13G/A, filed 15 May 2026).

Earlier secondaries took place in March and May 2025. There is one class of stock and no golden share, and the company is not a "controlled company" under NYSE rules (2026 proxy). Under the October 2024 Stockholders Agreement, Carlyle can still nominate six of nine directors while it holds at least 25%. That falls to four below 25%, two below 15% and none below 5%. For minority holders this means a sponsor with about a quarter of the economics shapes most of the board for now, its influence falls automatically as it sells, and its exit creates recurring supply of shares (risk 8.6).

Part 2 - Governance.

• Board independence. The 2026 proxy lists eight of nine directors as independent under NYSE rules, including Carlyle partner Doug Brandely and Carlyle aerospace head Fujiyama. The board waived the investor-designee provisions so that Masiello and Weingartner could stay on after Carlyle's designation rights shrank.
• Chair and CEO combined. Russell Ford held both roles until 30 September 2026 and is executive chairman until 31 December 2026. Paul McElhinney, the lead independent director since he joined the board in 2019 (2026 proxy), became CEO on 1 October 2026 and becomes chairman on 1 January 2027 (succession release, 2 June 2026). So the roles stay combined, and a new lead independent director will be needed. Per the release and proxy, McElhinney spent 30 years at General Electric, including as President and CEO of GE Power Services and CEO of GE Aviation Services, and earlier in legal and business-development roles at GE Aviation and GE Capital Aviation Services; the documents give no dates for those roles. The 2026 proxy also lists him as Senior Operating Partner at AE Industrial Partners and chair of AIM MRO, Moeller Aerospace and Columbia Helicopters. The filings read do not say whether he keeps those roles as CEO.
• Internal controls and audit. The October 2024 prospectus disclosed material weaknesses in internal control. Their full remediation status was not confirmed in the documents reviewed. The audit moved from PwC Canada to PwC US in November 2024, within the same network. This is not an auditor dispute.
• Pay and related parties. Executive pay combines an annual incentive with long-term awards that include performance share units (2026 proxy). Related-party flows with Carlyle are limited to the Stockholders Agreement and registration rights, and amounts due to related parties were nil at 30 June 2026 (Q2 2026 10-Q).

Part 3 - Capital returns.

Dividends: none. StandardAero has paid no dividend in FY2023, FY2024 or FY2025, or since its October 2024 IPO; before that it was privately held. Capital has gone into debt reduction (leverage fell from about 3x to 2.6x net debt to adjusted EBITDA, inside the 2-3x target), capacity, licences and acquisitions.

Buybacks and dilution: The board approved a US$450 million repurchase programme in December 2025, the company's first.

• Executed so far: 3,555,966 shares for about US$101 million in H1 2026 (Q2 2026 10-Q). That was 2,008,615 shares in Q1 at an average $30.17, including a 1,637,465-share private purchase from a GIC affiliate at $30.54 alongside the January secondary, and 1,547,351 shares in Q2 at $26.08.
• About US$349 million of the authorisation remained after H1, by arithmetic.
• No buybacks before December 2025.
• Last ~90 days (MoatMap): the only buyback entries are the two quarterly totals above (US$60.7 million and US$40.4 million), disclosed in the 10-Q filed 7 August 2026. Purchases made from July to September 2026 will not be visible until the Q3 10-Q.
• Share count over three years: up, not down. It was roughly 281 million before the IPO (derived from the 53.25 million new shares the IPO issued), about 334 million at end-2025 and 330.9 million at 30 June 2026. That is net growth of about 18% over three years from the IPO's primary issuance, trimmed by about 1% from the post-IPO peak.

Verdict: Neutral. The first buyback is real but young and has partly served to absorb sponsor and GIC selling, there is no dividend, and the IPO-driven share increase outweighs the repurchases so far.

11. Insider Activities

Sources. The MoatMap block (current to 9 October 2026) was the starting point. The SEC EDGAR Form 4 filings were then checked directly. EDGAR shows more transactions than the block: the block captured three trading days of the CEO's sales (5, 7 and 10 August), while EDGAR shows ten trading days of sales across five Form 4s, all under the same plan. All are shown below, along with other material insider and substantial-holder activity in the past 12 months.

Buys. There were no open-market purchases by any director, officer or substantial holder in the 12-month window.

Sells.

• The CEO's sales. Russell Ford sold 311,423 shares (~US$9.5 million) between 1 July and 10 August 2026. That was all through a family LLC, and all under a Rule 10b5-1 plan adopted on 18 August 2025 (footnote to each Form 4), almost ten months before the 2 June 2026 retirement announcement. The indirect holding roughly halved, from 606,955 to 295,532 shares, with 14,342 more held directly. A plan adopted well before the sales, followed by a pre-announced retirement, is consistent with planned diversification at the end of a 13-year tenure. The filings themselves give no stated reason.
• The sponsor sales. Carlyle and GIC are executing a disclosed private-equity exit through underwritten offerings, the normal end of a sponsor's holding period, not a judgement on the business.

Net assessment. Insiders were net sellers, but the selling is concentrated in two predictable sources: the departing CEO's pre-scheduled plan and the IPO sponsors' staged exit. No other officer or director sold in the open market, and nobody bought. The new CEO's personal dealings will be the more informative signal from here. The read is neutral. The selling is sizeable but fully explained by plan timing and sponsor structure, though the lack of any offsetting insider buying means there is no positive signal either.

12. Scenarios

Bull case. The licence-led model compounds. LEAP shifts into heavy performance restorations sooner than management fears, because operators push engines harder while new-aircraft deliveries stay short. StandardAero wins several more multi-year airline and lessor fleets, turning San Antonio into a second CF34-style growth engine. Winnipeg fills with booked CF34 work, the AE 1107/2100 award and the new licence expansion lift military and engine-services earnings from 2027, and Unified Turbines plus the back-shop moves give CRS a lasting cost and turn-time edge in a parts-short market. Without pass-through material, cash conversion improves visibly, allowing buybacks to absorb Carlyle's remaining stake without strain. McElhinney uses OEM-side relationships from GE to win more OEM-directed licences. In two to three years StandardAero looks less like a sponsor-owned overhaul shop and more like the default independent partner for OEMs that would rather license than build.

Base case. Management delivers roughly what it has guided, late on some items. LEAP grows steadily but stays mostly light workscopes until about 2028-29, with the heavy wave arriving around the end of the decade. CF34 and CFM56 stay strong through their overhaul peak, military work comes through unevenly as engines arrive, and business aviation grows with the HTF7000 fleet. Free cash flow improves but swings each quarter with castings and forgings deliveries, as the 2025-26 record suggests. Carlyle keeps selling in blocks, and the board's composition shifts as its designation rights fall away. The leadership handover is orderly, with perhaps a guidance reset at the first or second McElhinney call. The company in 2028 is recognisably the same business, larger and more LEAP-weighted, with full-year guidance still mostly met and the decade-end LEAP target still pending.

Bear case. 8.1 and 8.3 compound. LEAP durability improvements and an expanding Premier network push heavy-visit volume out and thin pricing, just as a renewed castings shortage strands engines in the shop and swells contract assets, so the growth story and the cash story slip together. 8.5 then hits: a prolonged fuel shock makes airlines park older CF34 and CFM56 aircraft and burn green time, softening the core that was funding the LEAP ramp. 8.4 makes it worse if CRS cannot staff up to offset parts scarcity. All this happens under 8.6: a new CEO resets expectations while Carlyle keeps selling, and the stock overhang becomes the market's lens for every miss. The licences hold (8.2 does not trigger), but the business spends two or three years waiting rather than growing.
