LMT: The Margin Story Repeats — And Now It's Two Quarters

The Q2 2025 collapse this page originally framed — gross margin to 4.04%, EPS $1.46 — was easy to dismiss as program-charge volatility. Q1 2026 made that dismissal harder.

Revenue $18.0B, flat against Q1 2025's $18.0B. The flat top line on its own is a signal: with Greece's €4B Achilles Shield deal in the backlog, Peru's $1.5B F-16 Block 70 award booked in Q1, and $7B of PAC-3 contract orders in the same quarter ($2.2B for 2026 deliveries plus a $4.8B undefinitized award to expand production), zero year-over-year growth means current-period revenue recognition is bottlenecked. Backlog has reached $194 billion — about 2.5x annual revenue — but backlog is contracted future revenue, not converted earnings.

The earnings line shows where the bottleneck hits the P&L. Net earnings $1.5B vs $1.7B prior year. Diluted EPS $6.44 vs $7.28. Free cash flow swung from +$955M to -$291M — Lockheed didn't generate cash this quarter, it consumed it. Cash from operations dropped from $1.4B to $220M. Management still guides full-year 2026 FCF of $6.5–6.8B, which means everything has to come in the back three quarters. The Q1 burn is supposed to be working capital and billing timing. The market priced it as something more durable: shares fell ~6.3% on the print and another ~10% over the following sessions to $513.45.

Aeronautics took a $125M unfavorable F-16 program adjustment plus $55M of C-130J challenges, dropping operating profit to $619M (down from $720M). RMS fell 19% on lower radar program volume and helicopter headwinds. Space operating profit dropped 26% as one-time favorable program completions that boosted Q1 2025 didn't repeat. MFC was the lone bright spot — operating profit up to $500M from $465M, but even MFC's margin was 10bp narrower at 13.7%.

Q2 2025 plus Q1 2026 isn't a charge cycle. It's a pattern. The defense-prime margin model assumes recurring program-charge events get smoothed by the rest of the portfolio. With four segments contracting simultaneously, there's no smoothing left.

Defense primes don't trade in isolation. The Q1 2026 reporting cycle put RTX, Northrop Grumman, and Lockheed on the tape within a week of each other, which makes the relative-margin question concrete rather than theoretical.

RTX Q1 2026: revenue $22.1B (+9% YoY), adjusted EPS $1.78 vs $1.51-1.52 consensus (a beat). Consolidated segment margin expanded 70 basis points despite a year-over-year tariff headwind. Same macro, different outcome.

Northrop Grumman Q1 2026: revenue $9.9B (+4% YoY), diluted EPS $6.14 (+85% YoY). Segment operating margin moved from 6.0% to 10.8% — nearly a doubling of segment operating income year-over-year, led by Aeronautics Systems and Mission Systems. Management's 2026 segment-margin guide implies a low- to mid-11% rate, with margin expected to widen through the year.

General Dynamics: reports April 29. The 2026 guide is operating margin ~10.4% on revenue of $54.3-54.8B, up about 20bp. GD's operating margin has been running near 10.2% in recent reporting periods.

Lockheed Q1 2026 segment margins: Aeronautics 8.9%, MFC 13.7%, RMS 10.6%, Space 8.2%. Three of the four are below the 11% mid-point of NOC's full-year guide. None expanded year-over-year. (Our BA vs LMT vs RTX defense-prime comparison sets the relative-positioning frame this Q1 print updates.)

This matters for the multiple. At Q1 2026's $513.45 closing price, LMT trades at roughly 22-23x forward consensus EPS — a discount to where it was when this page was first published, but still rich in absolute terms for a business where every operating segment just compressed simultaneously. RTX expanded margins through a tariff headwind. NOC nearly doubled segment income. LMT did neither. The peer-relative case for paying defense-prime multiples to own LMT rather than RTX or NOC has weakened in a single reporting cycle.

The bull retort is that LMT's mix is heaviest in the long-cycle programs (F-35, missile defense, hypersonics, GMD) where the margin pressure is mostly working-capital timing rather than competitive deterioration. That argument needs Q2 2026 and Q3 2026 to confirm it. After two consecutive misses, it doesn't get the benefit of the doubt anymore.

Most defense-prime articles wave at "tariff exposure" and move on. With the Bessent oil-enforcement framework live, China's reciprocal 125% tariff on US imports, and explicit Chinese export controls on rare-earth elements and high-performance magnets, the F-35 supply chain is no longer abstract risk.

A single F-35 contains an estimated 400-900 pounds of rare-earth materials — distributed across engine alloys, radar systems, electronic-warfare modules, and actuator power systems. China refines roughly 85-90% of global rare-earth supply and produces over 90% of high-performance magnets. Two days after the 145% Trump tariff on Chinese goods landed, China imposed export controls on seven rare-earth elements, then expanded the controls six months later to specifically target defense suppliers.

Lockheed's CFO told the Q1 call that the company had enough rare-earth supply set aside "to last at least through the rest of 2025". That cushion is two reporting periods deep. New procurement rules taking effect January 1, 2027 will ban Chinese-sourced rare earths from the entire US defense supply chain — mine to finished product. The transition window between today and that deadline is the live problem. Avionics, actuator and aero-engine manufacturers are reporting longer lead times and higher costs already. Howmet Aerospace has invoked force majeure on tariff-impacted shipments — a structural rather than commercial signal.

The FY2026 NDAA, signed December 18, 2025 (P.L. 119-60), formalizes this in procurement law. It raises Cost Accounting Standards thresholds for contractors, mandates DOD supply-chain-resiliency programs, and explicitly directs more spending toward developing qualified secondary sources for critical readiness items. "Critical readiness items" reads as policy euphemism for everything inside an F-35 that currently has a single Chinese-sourced input.

For LMT specifically, the F-35 program is the central exposure. Over half of the 20 nations involved in the F-35 program are integrated into the manufacturing base as suppliers or industrial participants. Howmet's force majeure letter, while limited mostly to commercial markets, included language that did not fully exempt military programs. The Q1 Aeronautics segment took a $125M F-16 program adjustment — a separate item from rare earths, but a reminder that program charges in the long-cycle international fighter business are not a finished story.

Net of all this: rare-earth supply security is a 2026-into-2027 margin headwind, not a known-quantity shock. RTX absorbed tariff cost in Q1 and still expanded margin. Whether LMT can do the same depends on the same execution machinery that just produced two miss quarters in a row.

When this page first published, LMT was at $627.43, trading on $21.48 trailing EPS for a 29x multiple. As of April 24's $513.45 close, with 2026 consensus EPS of around $22-23 (post-Q1-miss revisions), the forward multiple sits closer to 22-23x. The de-rating has happened.

The question is whether 22-23x is cheap enough.

At today's price, LMT trades at roughly 13-14x book value (down from 16.62x at the original print) and offers a dividend yield around 2.5%. The payout itself is well-covered by management's $6.5-6.8B FY2026 FCF guide, but that guide depends on Q2-Q4 2026 reversing the Q1 cash burn. Treasury 10-year yields sit at 4.34% per FRED's most recent settled print, which puts the equity-risk-premium math in a less forgiving place than it was at lower yields. A 22x multiple on a defense prime that just compressed every segment margin simultaneously, in a 4.34%-10Y environment, is not screaming-cheap territory.

Free cash flow gives the harder anchor. Trailing FCF before Q1 2026's negative print was running near $6.4-6.5B annually. The market cap at $513.45 is roughly $120 billion. That puts FCF yield around 5.3-5.4% on trailing data — assuming the FY2026 guide holds. Compare to a 4.34% 10Y yield: about a 100bp risk premium for a business with $194B in backlog but four segments that just contracted in unison. Investors who require a wider spread to own equity over Treasuries find this thin.

Backdrop matters too. CPI is running 3.3% year-over-year (FRED, March 2026 vs March 2025). Bessent's oil-enforcement framework is keeping Brent at $103+ with episodic spikes — energy is a direct passthrough into LMT's industrial cost base, not just a macro overlay. The Fed funds rate at 3.64% gives the model a floor on discount rates that's higher than where the original article was written, even before factoring next week's FOMC.

The valuation argument that worked in October 2025 and February 2026 — that LMT was a defensive growth compounder priced for execution — is now an argument that needs Q2 2026 to deliver. The original article said "watch April 21". April 23 (the actual print) showed margin compression in every segment. The next test is the July 2026 Q2 release.

Three near-term catalysts shape the next 90-180 days, and the Q1 2026 print recalibrated all three.

FY2027 budget cycle and DOD supplemental aid: Congressional defense markups typically begin in May/June with NDAA committee work. The FY2026 NDAA (P.L. 119-60) is now law; the FY2027 cycle is what shapes 2027-2028 program funding. With the Bessent oil-enforcement framework, ongoing Hormuz-related shipping disruption, and renewed Hezbollah escalation in Lebanon, Pentagon supplemental aid requests are realistic. Lockheed's PAC-3 franchise is the direct beneficiary — the Q1 $7B PAC-3 awards (including the $4.8B undefinitized contract to expand production) is a leading indicator. Any further supplemental aid for Israel or Ukraine routes through PAC-3, GMLRS, and Javelin systems where MFC has dominant share. MFC was the only segment with growing operating profit in Q1; it's also the segment most levered to a supplemental.

Pentagon tariff-exemption posture: Critical-readiness items (the FY2026 NDAA term) is the operative phrase. The Trump administration has historically issued waivers for components without viable domestic substitutes — the 2022 Chinese-alloy F-35 engine waiver is the precedent. The market hasn't priced explicit broad tariff exemptions for defense primes; if they materialize, the LMT margin headwind drops materially. If they don't, Aeronautics segment margin pressure intensifies through 2026 as the rare-earth cushion runs out.

Replenishment demand: Ukraine, Israel, Saudi/Gulf air-defense replenishment, and the F-35 Block 4 upgrade pipeline are all live. The Greece Achilles Shield deal (€4B, integrated air and missile defense) is the European template. Peru's Block 70 F-16 contract ($1.5B for 12 aircraft, optional second squadron) shows the Latin American pipeline is moving too. None of this rescues Q2 2026 margins on its own, but it does explain why the bull case for LMT survives a two-quarter margin pattern: the demand environment is structural, the question is throughput.

Against those tailwinds, two specific risk dates frame the next year. July 2026 Q2 earnings is the first chance to demonstrate that Q1 cash conversion improves and that segment margins stabilize rather than compress further. January 1, 2027 is the rare-earth procurement-rules deadline that takes Chinese inputs out of the F-35 supply chain entirely. If Q2 2026 misses again or guides cash flow lower, the de-rating from 29x toward 20x has further to run. If Q2 confirms a stabilization and the rare-earth substitution path is on track, the current 22x prints as the buy.

The original version of this page asked whether Q2 2025 would be isolated. April 23's Q1 2026 answered: not isolated. The new question is what stops it being a third quarter in a row.

Three things have to print correctly in Q2 2026 (July) for the bull case to recover ground:

1. Cash from operations needs to rebuild. Q1's $220M was a working-capital and billing-timing collapse. If Q2 doesn't recover above $1.5B in operating cash flow, the FY2026 $6.5-6.8B FCF guide is in serious trouble — and so is the dividend coverage math investors are currently underwriting at the current price.

2. At least two of the four segment margins need to expand year-over-year. Currently zero of four did in Q1. NOC managed margin expansion across multiple segments simultaneously in Q1 2026; RTX expanded consolidated margin through a tariff headwind in Q1 2026. Both are 2026-Q1 data points peers cleared and Lockheed didn't.

3. The rare-earth cushion narrative has to evolve into a substitution narrative. "Enough through end of 2025" is a defensive disclosure. "Production-qualified secondary sources for X% of critical inputs" is a forward disclosure. The FY2026 NDAA explicitly funds the latter; the question is how aggressively LMT names progress on its quarterly calls.

If those three print, 22x forward goes from "still expensive" to "reasonable for the backlog". If they don't, the de-rate from 29x toward 18-20x continues.

Backbone catalysts haven't disappeared. NATO defense spending continues climbing. The Bessent oil-enforcement framework keeps the Hormuz-replenishment narrative live. Greece, Peru, and PAC-3 expansion all sit in the backlog as awarded but not yet recognized revenue. The structural demand thesis is intact.

What's broken is the assumption that defense-prime margin discipline is a given. Q2 2025 + Q1 2026 demonstrates that LMT specifically — distinct from RTX or NOC in the same quarter — can compress margins across all segments at once. Until July's print, the multiple should reflect that risk, not the demand backdrop alone.
