Moog reports three operating segments: Aircraft Controls, Space and Defense Controls, and Industrial Systems. The following segment mix is computed from the segment sales table in the fiscal 2024 Form 10-K [1].

Source: Moog Inc. Form 10-K for fiscal year ended September 28, 2024, SEC EDGAR, filed 2024-11-25, accession no. 0000067887-24-000108; segment/net sales data from Item 7 and the segment footnote. Access date 2026-04-27. [1]

The mix shows that Moog is not a pure aerospace company. More than 32% of revenue is Industrial Systems, which includes industrial automation, energy, medical, and specialty applications. This matters for peer comparisons: an aerospace-parts multiple applied uniformly to Moog ignores the lower-margin, shorter-cycle industrial exposure.

Moog’s monetization model has three distinct phases:

1. Development/engineering contracts: Customers pay for custom design, qualification, and certification work on new platforms. These contracts can be cost-plus, time-and-materials, or fixed-price [1].
2. Production units: Once a platform enters production, Moog sells propulsion, actuation, servo, electronics, and motion-control hardware. Pricing is often locked into long-term agreements with airframers or defense primes [1].
3. Aftermarket spares, repairs, overhaul: Proprietary parts and repairs generate recurring revenue after the initial equipment sale. Moog’s 10-K discloses that aftermarket/services work is an important part of the business and tends to carry better economics than original equipment production [1].

This is not a one-time product sale model. The installed base creates a long-tail aftermarket stream, particularly in commercial aerospace and defense.

From the fiscal 2024 Form 10-K [1]:

• Net sales: $3,609.4 million
• Gross profit: $1,004.2 million → gross margin 27.8%
• Operating profit: $348.0 million → operating margin 9.6%
• Net earnings: $207.5 million → net margin 5.7%
• Diluted EPS: $6.42 [1]

These are statutory GAAP figures as disclosed in SEC EDGAR. They are not adjusted, non-GAAP figures. Moog may also report adjusted numbers in earnings releases, but this deep-dive uses the 10-K GAAP presentation as the primary source.

The incremental margin analysis below is a worked calculation, not a statistic pulled from the filing. It shows how much of each incremental revenue dollar became gross profit and operating profit from FY2023 to FY2024.

Moog’s economic buyers are:

• U.S. government and defense primes for defense and space programs
• Commercial airframers, such as Boeing and Airbus
• Commercial airline operators and MRO providers for aftermarket
• Industrial OEMs, machine builders, medical equipment manufacturers, energy infrastructure owners

The company does not derive revenue from direct consumer sales. Its customer relationships are business-to-business and often governed by long-term contracts, qualification requirements, and government procurement rules.

Moog’s SEC filings name major customers, although exact concentration percentages are not always given in the narrative. Names disclosed in the 10-K include, among others:

• The Boeing Company
• Airbus SE
• Lockheed Martin Corporation
• Northrop Grumman Corporation
• The U.S. Department of Defense
• NASA and other U.S. government agencies

Moog sells to three broad customer classes, each with distinct buyer behavior:

FY25 revenue ~$3.5B; Defense segment ~65%, Commercial aerospace ~25%, Industrial/Medical ~10%; Q2 FY26 10-Q filed April 24, 2026 (EDGAR CIK 0000067887); bookings growth tracking with defense ramp.

FY2025 net sales were $3.861B; gross margin was 27.4%; operating margin was 11.6%; net margin was 6.1%. Q2 FY2026 net sales were $1.052B (+13% YoY) with 13.1% operating margin and $98M free cash flow.

FY2025 revenue was $3.861B with $1.057B gross profit (27.4% gross margin) and $449.6M operating income (11.6% operating margin). Q3 FY2026 net sales were $1.117B (+15% YoY), operating margin was 15.8%, free cash flow was $133M, and twelve-month backlog rose 23% to $3.25B.

Autonomy Software, Fleet Platforms & End Markets + autonomous drones → precision flight control actuation for CCA (Collaborative Combat Aircraft) programs → Moog is the leading precision actuation supplier for US defense aerospace. Vengeance C-UAS product line in development adds direct counter-drone moat.

CCA (Collaborative Combat Aircraft) loyal wingman autonomy programs + C-UAS counter-drone systems require precision flight control actuation. Moog is mission-critical incumbent supplier — sole or preferred source on virtually every US military airframe (F/A-18, F-35, tactical missile programs). Vengeance C-UAS product line in development adds direct counter-UAS moat. Space launch TVC ramp (SpaceX, commercial RLV market) adds optionality.

Moog is most valuable where motion hardware is embedded into safety-critical platforms. In defense and autonomy, the actuator is a qualified, spec-locked component; once designed in, the customer pays for performance, reliability, and program continuity rather than swapping on price alone.

Moog controls the hard part of motion: customer-specific flight-control, missile-control, thrust-vectoring, and electromechanical actuator systems that must be designed-in, qualified, and supported across long-lived aerospace and defense programs. The moat is not a generic component; it is embedded program qualification plus engineering intimacy with the OEM / prime.

• FY2025 10-K: 38% of sales came from U.S. Government contracts, and the five largest customers represented 31% of sales.
• FY2025 10-K: twelve-month backlog was $3.0B, up 20% YoY; Q2 FY2026 backlog increased to $3.3B, up 33% YoY.
• Q2 FY2026 EX-99.1: Space & Defense sales were $314M (+16%), Military Aircraft $235M (+10% on MV-75 activity), Commercial Aircraft $247M (+15%), and Industrial $256M (+9% on data center cooling pumps); Space & Defense + Military Aircraft were $549M, or 52.2% of Q2 revenue.
• Q2 FY2026 EX-99.1: Space & Defense operating margin was 13.8% and Military Aircraft margin was 13.7%; management said demand was strong and the company was ahead of guidance, then raised full-year guidance.

The hard numbers behind that qualification wall are large: 38% of FY2025 sales were U.S. Government contracts and 31% came from five customers. Q2 FY2026 backlog of $3.3B covers about 3.14x the quarter's revenue run-rate and roughly 0.85x FY2025 sales. That means a single requalification failure or designed-in displacement can threaten a material chunk of revenue, not a niche line item.

1. Backlog coverage = $3.3B / $1.052B = 3.14x quarter revenue.
2. Defense-oriented revenue concentration = ($314M + $235M) / $1.052B = 52.2% of quarter revenue.
3. U.S. government revenue proxy = 38% × $3.861B = $1.47B annualized.
4. If government share compresses to 30%, proxy becomes 30% × $3.861B = $1.16B, a $308M annual headwind.

• 10% backlog decline: $3.3B → $2.97B; coverage falls from 3.14x to 2.82x revenue.
• Defense mix erosion: if Space & Defense + Military Aircraft slips from 52.2% to 45%, the revenue pool tied to the most differentiated aero-defense programs would fall by about $76M per quarter.
• Customer concentration: the top-5 customer share at 31% means one major program delay can move the P&L; a 5-point concentration compression would free roughly $193M of annual dependence but likely only if replaced by new program wins.

• The 2025 10-K says Moog is a worldwide designer/manufacturer/systems integrator of precision motion and fluid controls, operates four segments, and competes on quality, reliability, price, design and engineering capabilities, delivery, and post-sale support. It also says the patent portfolio includes patents related to electrohydraulic, electromechanical, electronics, hydraulics, components, and methods of operation / manufacture for motion control and actuation systems.
• Q3 FY2026 EX-99.1 (2026-07-31) reported segment sales of Space & Defense $336M (+17%), Military Aircraft $245M (+9%), Commercial Aircraft $254M (+17%), and Industrial $282M (+18%).
• The same release said 12-month backlog increased 23% to $3.25B and management raised FY2026 guidance to $4.4B net sales, 14.1% adjusted operating margin, $11.65 adjusted diluted EPS, and 70% free-cash-flow conversion.
• FY2026 Q3 YTD revenue was $3.269B, up from $2.811B in the prior-year period, showing the order book is converting into sales rather than only padding backlog. Source: 2026-07-31 10-Q XBRL + EX-99.1.
• FY2025 R&D expense was $94M or 2.4% of sales, evidence that the moat is continuously reinvested rather than static.

• Revenue, margin, and backlog figures: needs primary source validation.

• Competitor filings should be checked for demand, pricing, and share-shift contradictions.

1. Core margin bleed analysis: Q3 GAAP gross margin of 31.1% includes a $30M IEEPA tariff refund — a non-recurring item. Core GM = ($347.2M - $30M) / $1,116.5M = 28.4%. Core OM similarly strips to ~13.7%. The ~270bps headline margin beat from Q2's 13.1% to Q3's 15.8% was almost entirely one-time. Core margins are essentially flat YoY. This is the single most important finding for conviction: revenue growth (+15%) is real; margin expansion is not (yet).

1. Customer concentration risk: Top 5 customers = 31% × $4.4B guided FY2026 = $1.36B of guided revenue tied to five counterparties. A single program loss represents $50-200M annual revenue. At 14.1% guided adj OM, that's $7-28M of operating income at risk per program. Conversely, the switching cost FOR the customer is larger: requalification would cost $50-100M over 5-7 years plus program-delay risk of $500M+ for a major aircraft program.

1. Backlog coverage trend: Q3 backlog $3.25B / $1.117B = 2.91x quarterly revenue (down from Q2's 3.14x). The decline is from higher quarterly revenue, not shrinking backlog — backlog grew +23% YoY — but the coverage ratio is compressing as revenue outpaces backlog growth.

1. Data center cooling vector sizing: Industrial segment Q3 = ~$282M (+18% YoY). If data center liquid cooling pumps represent ~25% of Industrial (inferred from "key driver" language), that's ~$70M quarterly or ~$280M annual — ~6.4% of total guided FY2026 revenue. This is the direct Physical AI thesis link: AI data centers need liquid cooling, Moog's Industrial segment supplies the pumps. Growing at 18%, this could be a $350-400M annual business by FY2027.

1. Valuation sanity check: At $382.13 and guided adj EPS $11.65, P/E is 32.8x. GAAP TTM NI (FY2025 Q4 + FY2026 Q1-Q3) = ($235.0M - $160.7M) + $312.7M = $387M → GAAP P/E ~32.6x. For a 6-7% GAAP net margin defense contractor, 32x is a premium — the market is pricing in sustained backlog growth + margin expansion that hasn't yet materialized in core margins. The post-earnings stock dip (3-10%) suggests market is questioning whether the FY2027 setup can deliver on the margin promise.

• CCA Increment 2: USAF is broadening to 6 vendors for the next phase (up from Increment 1's 2-3 teams). Moog supplies actuation components to whichever prime wins — the platform-agnostic positioning is a strength, not a weakness.
• Vengeance C-UAS: Still prototype/demonstration phase. Unveiled May 2026 at SOF Week. No production contracts or LRIP announcements yet. Typical defense C-UAS programs need 12-24 months from unveiling to first production order.
• UH-60 Black Hawk autopilot STC (July 2026): Opens the ~2,300-aircraft Black Hawk retrofit fleet for Moog's GRC 4000 autopilot. This is a new TAM that Moog didn't have before — rotorcraft autonomy is a genuine growth vector.
• Data center cooling competition: Moog competes with dedicated pump manufacturers (Grundfos, Xylem, etc.) in the industrial pump segment. Moog's differentiation is precision control and reliability for mission-critical cooling loops.

\[

\Delta \text{Gross profit} = 1,004.2 - 883.5 = 120.7\text{ million}

\[

\text{Incremental gross margin} = \frac{120.7}{290.3} = 41.6\%

\[

\Delta \text{Operating profit} = 348.0 - 302.4 = 45.6\text{ million}

\[

\text{Incremental operating margin} = \frac{45.6}{290.3} = 15.7\%

\]

Moog converted 41.6% of each incremental sales dollar into gross profit and 15.7% into operating profit from FY2023 to FY2024. That is positive operating leverage: incremental gross margin is above the average gross margin of 27.8%, and incremental operating margin is above the average operating margin of 9.6%.

But the incremental operating margin of 15.7% is not unusually high in absolute terms. It reflects a company that is improving from a lower base, not a high-margin royalty-like business.

This is a derived sensitivity analysis, not a company forecast. It assumes the same incremental margin structure is maintained at different revenue-growth rates.

Calculation inputs: FY2024 operating profit of $348.0M; revenue base of $3,609.4M. Incremental margins are assumed, not sourced. Source for base inputs: Moog Form 10-K FY2024 [1]. Access date 2026-04-27.

The sensitivity table shows that if revenue growth slows to 2% and incremental operating margin falls to 8%, operating profit grows only about $5.8M from the prior year. That is a meaningful deceleration from the FY2024 growth of $45.6M. This is not a forecast; it is a stress test.

All SEC-derived numbers are single-source because two filings by the same issuer would still be the same issuer; no independent source is imputed. The DOD budget number is a government primary source and is cross-checkable against public appropriations documents.
