Impact of Clinical-Stage siRNA Asset on Madrigal's Pipeline and Growth

Bottom line: defense growth should be margin-supportive, but Moog is explicitly balancing it with higher investment costs

In Q2 2026, Moog linked the defense market upturn (including requests tied to higher U.S. defense spending direction) to strong order/backlog and profitability, and it expects to continue funding capacity/capability expansion to deliver higher production rates—actions that can be margin-positive over time if operational efficiencies keep pace, but can also be margin-dilutive in the near term due to added R&D and readiness/product-development spend.

1) What Moog says is driving the defense growth / spending backdrop

• Moog characterized the defense environment as being on a “completely different trajectory versus different cycles,” citing a “White House” request of $1.5 trillion for fiscal ’27, and that the direction of that number appears at least ~20% higher than fiscal ’26 (even if the full amount may not materialize). ¹
• Management also stated demand is strong and referenced a “structural shift in the defense market,” with activity driven by the need to boost U.S. defense industrial manufacturing capacity. ²
• Moog gave an operational example of how defense production is expected to ramp: production rates on key missile defense programs are anticipated to increase by factors ranging from 2 to 4x over the next few years. ²

2) Q2 2026 evidence that defense growth is not hurting gross margin (it’s supporting company profitability)

While your question is specifically about gross margin, the excerpts don’t provide a standalone gross margin rate. What Moog does provide is evidence of segment operating margin strength during Q2 alongside defense demand growth—operating margin is downstream of gross margin and cost structure, and it indicates that increased defense output has not caused an overall margin collapse.

• Moog reported Space & Defense operating margin of 14.6% in Q2, up 200 bps year over year. ³
• That increase was “driven by profitable sales growth,” partially offset by “increased product development, business capture and operational readiness investments.” ³
• Moog also reported Space & Defense demand strength and specific defense sales growth: Space & Defense sales were $314 million, up 16% year over year, described as reflecting broad-based defense demand. ⁴
• Additionally, Moog said it delivered “double-digit revenue growth” and “record” backlog, including 12-month backlog up 33% year over year. ²

Implication for gross margin: Moog’s narrative suggests that as defense volumes ramp, the business is capturing economics from “profitable sales growth” and competitive wins, while absorbing some incremental development/readiness costs. ³ If those costs are managed well, gross margin pressure would be limited; if they spike, gross margin could face temporary dilution until scale benefits catch up.

3) Management’s explicit “growth vs. investment” tension that can affect margins (including gross margin)

Moog directly acknowledges it must invest to meet higher defense production rates, and it ties that to operational readiness and additional R&D later in the year—both of which can pressure gross margin if they increase cost of revenue faster than pricing/volume benefits.

• Management said it is “proactively investing in capacity and capability” (facilities, equipment, automation, supplier resilience), plus “onboarding and upskilling of talent” to support next-generation production, and it will keep investing to deliver at higher production rates. ⁵
• In discussing outlook/guidance, Moog explained that Space & Defense operating margin is expected to “continue to contribute,” but it is also “making additional investments in R&D because [it has] such great opportunities,” and that this is in the context of tariff pressure that offsets some margin headwinds. ⁶
• Moog also noted tariff-related margin pressure elsewhere, reporting adjusted operating margin of 13.4% despite 110 bps of pressure from tariffs, and it highlighted the interplay between underlying performance and cost pressures. ⁷

Implication for gross margin: The defense spending-driven volume ramp should provide a mechanism for scale and throughput benefits (supportive), but Moog is simultaneously planning incremental costs (capacity expansion, R&D, readiness) that can reduce gross margin in the nearer term until production efficiency ramps.

4) Net effect on gross margin expectation from Moog’s Q2 2026 posture

Given the lack of a direct gross margin figure in the excerpts, the most supportable conclusion is:

• Directionally supportive: Defense growth is associated with profitable sales growth and higher Space & Defense operating margin in Q2 despite investment items. ³
• Not automatically margin-enhancing in the near term: Moog explicitly expects additional R&D investment in the second half even while operating margin contribution continues—consistent with possible gross margin dilution risk from higher cost absorption before benefits fully materialize. ⁶
• Offsetting forces likely matter: Moog references operational simplification/80/20 and pricing reviews as mechanisms to reduce lead times, increase throughput, and ensure readiness—actions that can protect/raise gross margin as volumes increase. ⁵
• External cost pressures are real: Tariffs are explicitly discussed as a margin headwind that Moog offsets with underlying performance/pricing and sales growth; this is relevant because tariffs can affect gross margins via input costs. ³⁷

Conclusion

Based on Moog’s Q2 2026 commentary, the growth in the defense market and the expected higher U.S. defense spending trajectory should be margin-supportive because Moog is experiencing profitable defense sales growth and higher Space & Defense operating margin in Q2. ²³⁴ However, the same ramp requires substantial capacity, capability, and readiness investment and additional R&D later in 2026, which can place near-term pressure on margins that flow through from gross margin, even if the long-run economics improve. ⁵⁶

Note: The excerpts provided do not include Moog’s specific gross margin rate in Q2 2026, so the impact can only be inferred from operating margin drivers and management’s described cost/investment behavior. ³⁶
