Rheinmetall: Respect Without Urgency for a Re-Rated Defence Prime
Rheinmetall is Germany's dominant defence prime, an ammunition-and-land-systems specialist riding a record €73.0bn backlog as European rearmament accelerates past €380bn in 2025 defence spending. FY2025 continuing sales rose to €9.94bn at an 18.5% margin, led by a 29.3% margin in the core Weapon and Ammunition unit, but June's abrupt cancellation of the F126 frigate programme wiped out nearly a fifth of the share price in a single day, exposing how much of the celebrated backlog is framework rather than firm order intake. Rating Hold: a genuinely stronger, cleaner defence business than it was two years ago, but a stock still priced at roughly 40x earnings for execution that has not yet been proven immune to political reversal.
49/100
Saab: Europe's Sovereign Defense Franchise Is Real, but the Margin of Safety Is Gone
Saab is Sweden's sovereign defense-systems house, supplying radar, missiles, Gripen fighters, submarines, and lifecycle support against a SEK 274 billion order backlog built on Europe's post-2022 rearmament. Q1 2026 sales grew 21% and EBIT 32%, the balance sheet stayed net-cash positive, and 72% of backlog is now international, yet the stock trades near 48x trailing earnings after a re-rating that already prices in unbooked wins like GlobalEye and further Gripen campaigns. Rating Hold: a genuine sovereign-systems compounder, but at SEK 564 the margin of safety is gone.
44/100
RBC Bearings: The Moat Is Real, but the Price Already Assumes the Aerospace-Defense Story Is Finished
RBC Bearings is a niche U.S. manufacturer of qualification-protected precision bearings, engineered components, and fluid-control systems for aerospace, defense, and industrial platforms, shaped over three decades by founder-CEO Michael Hartnett's 29-deal acquisition program. Fiscal 2026 revenue reached $1.87 billion as Aerospace & Defense sales grew 32.9% against 3.8% Industrial growth, backlog surged to $2.3 billion, and the stock re-rated toward premium defense-compounder multiples (about 48x adjusted EPS) even as owner-earnings yield fell near 1.8%, below the 4.27% 10-year Treasury yield. Rating Watch: an excellent, moat-protected compounder, but today's price already discounts years of successful mix conversion, leaving the ideal buy zone at $290-340.
41/100
Leonardo: A Re-Rating With Real Earnings Behind It, Priced Like the Quality Gap to BAE and Thales Is Already Closed
Leonardo S.p.A. is Italy's state-influenced aerospace and defense group, whose profit engine sits in defense electronics and helicopters and is now backed by a €56.8 billion Q1 2026 order backlog. FY2025 orders reached €23.8 billion and EBITA €1.75 billion as Europe's rearmament cycle drove a sharp re-rating, yet the stock now trades near a 30.9x trailing P/E, roughly matching cleaner peers such as Thales and BAE Systems even though Leonardo still carries a persistent state-governance discount and weaker aerostructures drag. Rating Hold: order momentum and cash generation are real, but the price already assumes much of the quality convergence that has not yet fully happened, leaving the ideal buy zone at €39-43.
46/100
Thales: A Genuine Defence-Electronics Quality Compounder, Priced Like the Best Case Is Already Locked In
Thales is a French defence-electronics and aerospace group whose 2025 sales reached €22.1 billion with free operating cash flow of €2.58 billion, now expanding into naval robotics through the Exail acquisition after absorbing Germany's F126 contract termination. Rating Hold: at €241.10 the stock already trades above its own historical average multiple, pricing in continued defence-cycle strength and a smooth Exail integration, leaving the ideal buy zone at €160-170.
53/100
HEICO Corporation: In-Depth Research
HEICO got its start in FAA-PMA replacement parts and high-reliability electronics, and has turned the aviation aftermarket into a compounding growth platform through a steady cadence of tuck-in acquisitions. In FY2025 its two segments, Flight Support and Electronic Technologies, contributed roughly 3.117 billion and 1.413 billion dollars of revenue with first-rate quality; but at 331.61 dollars the stock trades near 50 times earnings, far above peer TransDigm at about 31 times, leaving almost no margin of safety. Rating Hold: a great company at an expensive price, worth buying back in the 235 to 260 dollar ideal-entry zone.
46/100
Airbus SE Deep-Dive Research
Airbus is one of the two dominant European-positioned civil aircraft makers, monetizing A320neo/A350 deliveries, lifecycle services, and defense and space programs. In 2025 it generated EUR 73.4 billion in revenue, EUR 4.57 billion in free cash flow before customer financing, and EUR 12.2 billion in net cash, but weak Q1 2026 deliveries turned cash flow negative and the full-year 870-aircraft target requires roughly 87 deliveries per month in H2; at EUR 179.28, the stock trades at about 25x forward PE and is not cheap. Report rating Hold: a high-quality mature cash cow, but the stock is paying for execution repair, has no current margin of safety, and is worth waiting for at a better entry point.
46/100
Rocket Lab (RKLB) Zen Horizon Research Report
Rocket Lab is the second-largest listed commercial space player after SpaceX, with a vertically integrated stack spanning rocket design, launch, satellites, and payloads. The core thesis rests on Electron small launchers, about 30% of launch services with 21 launches and a 100% success rate in FY2025, plus Space Systems at about 70%, including the SDA USD 816 million 18-satellite contract and the USD 275 million Geost acquisition that moves the company into military payloads. Research rating Watch: FY2025 revenue reached USD 602 million, backlog rose to USD 1.85 billion, and Q1 2026 revenue reached USD 200 million, but the delayed Neutron medium-lift rocket, now pushed to Q4 2026, remains the key valuation turning point.
51/100
Safran SA (SAF.PA) — Zen Horizon Report
Safran is France's leading narrowbody aero-engine champion, co-owning CFM International 50/50 with GE Aerospace (the CFM56/LEAP family powers the Boeing 737 MAX and Airbus A320neo, with roughly 75% share including the JV); 2025 revenue was €31.2B, split 78% civil aviation and 22% defense, with the aftermarket annuity (23,000 CFM56 plus 7,500 LEAP units in service) at the core of profit; defense has lately accelerated on France's LPM 2024-2030 act, and the CFM partnership with GE was renegotiated in 2025 to run through 2050. Rating Watch: a high-quality narrowbody-aftermarket annuity asset whose current price already fully discounts the roadmap, leaving thin margin of safety for new positions.
38/100
Voyager Technologies Research from a Long-Term Owner's Perspective
A defense-space contractor with an embedded Starlab commercial space-station option, Voyager remains deeply loss-making with negative owner earnings. The core thesis is that demand is real, but the company has not yet converted that demand into durable, distributable cash flow. Research rating Watch: at $44.96, the stock is already near the lower end of the optimistic scenario, with no margin of safety and an ideal buy range of $18 to $25.
39/100
Karman Holdings: A Long-Term Owner's Perspective
Karman Holdings sits in high-quality defense and space niches with deep customer embedding, but its current financial profile is still uneven. The core thesis is that this may become a good mission-critical aerospace and defense platform, yet 2025 operating cash flow turned negative, leverage is high, tangible book value is negative, and the current price of USD 51.84 is far above a reasonable intrinsic value range of USD 13-20. Research rating Watch: an emerging good business, but at a bad price.
36/100
Frequency Electronics: A Long-Term Owner's Research View
Frequency Electronics is a small-cap niche supplier of precision timing, atomic clocks, and microwave components for satellite payloads, defense communications, electronic warfare, and secure timing, with a narrow moat. The core thesis is that the business has improved, but the current price of $72.16 stands far above the three intrinsic value ranges of conservative $9-12, base $16-22, and optimistic $28-38, with an ideal buy range of $12-16. Research rating Watch: a technically credible niche compounder deserves attention, but not at a price that already discounts years of optimistic execution.
22/100
Mercury Systems: A Long-Term Owner's Study
A supplier of high-reliability electronics and signal-processing platforms for aerospace and defense, with gross margin recovering from a fall of 41.7% to 27.9%; at $112.87 the stock trades above 90x FCF, pricing in an excellent outcome while operating quality stays unproven. Rating Avoid: a strong industry attached to an unproven turnaround already priced for perfection, with an ideal buy of $25–35.
24/100
Kencoa Aerospace: A Value Study of an Aerostructures Supplier
The Buffett framework rates Kencoa Aerospace a Watch. The company has cleared the entry barriers of the aerospace supply chain and grew Q1 2026 revenue 45% year over year, yet free cash flow was negative for five straight years (2021-2025) and a perpetual convertible bond, if fully converted, dilutes existing holders by about 67.7%. At roughly KRW 23,700 the stock already prices in a strong turnaround; fair value sits at KRW 12,000-18,000 and an ideal entry at KRW 10,000-14,000, leaving no margin of safety. Rating Watch: a barrier-cleared turnaround small cap that has not yet proven it can convert orders into durable, distributable per-share cash flow.
42/100
Curtiss-Wright Research from a Long-Term Owner's Perspective
Curtiss-Wright is a high-quality aerospace, defense, naval nuclear, and industrial technology compounder with strong cash generation and embedded customer relationships. At $769 per share and a $28.5 billion market capitalization, the stock trades around 48x owner earnings and 56x P/E, while my DCF points to fair intrinsic value of $300-380 and an ideal buy range of $220-300. Research rating Watch: a good business at a bad price, with little margin of safety today.
35/100
Moog Long-Term Owner's View Research
Moog is a precision motion-control company with defensible positions in aerospace, defense, space, and selected industrial and medical niches. Fiscal 2025 revenue reached a record $3.861 billion and margins improved to 13%, but a material weakness in internal control, uneven FCF conversion, and a stock price near $373 leave no margin of safety against an intrinsic value range of $90 to $260 and a fair buy range of $95 to $145. Report rating Watch: a better business, but not yet a value-investing entry point.
30/100
Woodward: A Long-Term Owner's Perspective
A great company at a poor price. At roughly $344.7 today, a trailing P/E near 41.3x, and a market cap around $21.1 billion, Woodward is a genuinely durable cross-cycle earner with real engineering moats in aerospace and select industrial controls. But DCF and relative valuation both point to fair intrinsic value of $170-240, with an ideal buy range of $130-180, leaving no margin of safety at the current price. Rating Watch: a high-quality business that today looks far more like a bad price than a bad company.
44/100
Hexcel Long-Term Owner's View Research
Hexcel is a leading aerospace-grade carbon fiber and prepreg supplier, but it behaves more like a high-quality cyclical stock than a smooth compounder. At USD 88.04, the stock already prices in a recovery, while our neutral DCF is around USD 55 and fair buy range is USD 50-60. Research rating Watch: a good company, but with insufficient margin of safety.
39/100
Huntington Ingalls Industries: A Deep Value Investment Study
America's leading military shipbuilder, the only company able to build, refuel, and decommission nuclear-powered aircraft carriers and one of only two nuclear submarine builders, with customers that are almost entirely the U.S. government. Structural barriers to entry run extremely deep, yet ROIC sits only in the mid-single digits and cash flow swings sharply with contract timing, and at roughly $308 the market has already paid full price for that scarcity with little visible margin of safety. Rating Watch: a scarce strategic asset worth tracking, with an ideal buy range of $220-260.
43/100
Leidos Holdings Deep Value Investment Research
Leidos is the largest U.S. government technology and engineering contractor, with about 87% of revenue from the federal government and a profile of stable demand and real cash flow, but only a moderate moat and pricing power constrained by competitive bidding. At roughly USD 127.81, the stock sits near the lower end of a reasonable range: not expensive, but without an obvious margin of safety. Research rating Watch: a quality contractor worth tracking, with an ideal buy range of USD 95-110.
40/100
Textron Deep Value Investment Research
Textron is a multi-business group centered on aviation and defense with an industrial segment attached, earning money mainly through Cessna/Beechcraft business jets and Bell helicopters, with real brand and certification barriers but uneven moats across segments. At about $91.76, the stock trades at roughly 16-17 times conservative Owner Earnings, cheaper than peers but without enough margin of safety. Research rating Watch: a solid business worth tracking, with an ideal buy range of $72-$82.
43/100
Teledyne Technologies (TDY): A Long-Term Owner's Perspective
A multi-segment industrial-technology platform with solid cash-flow quality and cross-cycle resilience. But at $704 the stock already sits at the upper edge of an optimistic valuation, leaving conservative buyers without a margin of safety; the ideal buy-in range is $400-500. Rating Watch: a good company at too rich a price.
44/100
L3Harris Technologies: A Deep-Dive Value Investing Analysis
A mid-to-large U.S. defense contractor whose backlog has climbed to $40.7 billion with a book-to-bill of 1.4x; at a current PE of 34x it is pricier than most peers, so the rating is Watch with an ideal buy range of $230-250.
40/100
TransDigm Group: A Deep Value Investing Study
Aircraft proprietary-parts and aviation aftermarket giant with 90% proprietary-product sales, 55% aftermarket revenue, and a 53.9% EBITDA margin; at $1,213.51 the stock trades above our bullish upper bound, with an ideal buy range of $650-800. Rating Watch: exceptional business quality, but the current price offers no margin of safety.
45/100
Northrop Grumman: A Long-Term Owner's Perspective
One of the top U.S. defense prime contractors (No. 3 globally per SIPRI), spanning B-21, Sentinel, missile defense, and space systems; at $555.58 the stock trades at about 17.4x PE but 22.6-26.4x Owner Earnings, and with the Sentinel cost breach, B-21 margin pressure, and cash flow weaker than reported profit, we assign a Watch rating.
47/100
GE Aerospace Deep Value Investment Research
GE Aerospace is a global leader in commercial and military aircraft engines, with a vast installed base and excellent long-tail aftermarket cash flow. At the current price of $302.84, the stock has already moved above the upper end of an optimistic scenario, leaving too little margin of safety. Rating Watch: a high-quality compounder, but not an attractive new purchase at today's valuation.
44/100
Lockheed Martin: A Long-Term Owner's Perspective
The leading U.S. defense prime contractor, with F-35 accounting for 27% of 2025 sales and a year-end backlog of $193.6 billion. 2025 free cash flow was $6.9 billion. At the current $466 share price the stock sits within its fair-value band, but recurring program losses leave a thin margin of safety.
44/100
RTX Corporation: A Long-Term Value Study
A global aerospace and defense giant spanning aviation parts/systems, commercial aero-engines, and missiles/air defense, with a Q1 2026 backlog of $271 billion. At $177.01 and a 33.2x P/E, it is a good business at a full-to-rich price: the GTF powdered-metal event is still clearing and the margin of safety is insufficient. Rating Watch: worth respecting, but better to wait for a pullback.
47/100
Howmet Aerospace Deep Value Investment Research
Howmet Aerospace is a high-quality leader in aero-engine components and fastening systems, with a deep moat and steadily expanding margins. The core thesis is that the business is strong, but the current PE of about 59.5x already prices in years of high growth, smooth M&A integration, and sustained premium valuation, leaving too little margin of safety. Research rating Watch: an excellent aerospace compounder, but the ideal entry range is $90-125 rather than today's price.
