Northrop Grumman (NOC) FY2025 Earnings Quality Report

Grade: F — Cash/Debt Mismatch and Acquisition Goodwill Overhang

Framework: Schilit *Financial Shenanigans* + Beneish M-Score + forensic accounting principles

Data: SEC EDGAR 10-K (Filed January 27, 2026, FY ended December 31, 2025) + Yahoo Finance

Auditor: Deloitte & Touche LLP — Unqualified opinion (1 critical audit matter: revenue/cost-at-completion estimates on select long-term contracts) — auditor since 1975

One-line verdict: Northrop Grumman is a pure-play defense prime with 84% of 2025 sales coming from the U.S. government and a $95.7 billion backlog — but the balance sheet shows $17.4 billion of goodwill against $16.7 billion of equity, meaning every dollar of shareholder equity is backed by a dollar of acquisition goodwill from Litton, TRW, Grumman, Westinghouse and Orbital ATK. Cash of $4.4 billion covers only 26% of $17.0 billion in total debt. The real story of this 10-K is the B-21 Raider: after a $1.56 billion LRIP loss provision in Q4 2023, the company recognized an additional $477 million loss in Q1 2025 on the same five LRIP options. On the other hand, CFFO/NI is 1.14, FCF grew 26% to $3.3 billion, DSO is just 12 days (the company collects from the U.S. government faster than any conglomerate in this screen), and the M-Score of -2.44 is comfortably below the manipulation threshold. Net earnings rose from $2.06B in 2023 (B-21 loss year) to $4.17B in 2024 to $4.18B in 2025 — a doubling over two years even as the B-21 keeps absorbing losses.

The B-21 Raider — A Contract That Keeps Giving Losses

The MD&A disclosure on the B-21 is the most important accounting narrative in this 10-K. From Item 7:

"In 2015, the U.S. Air Force awarded Northrop Grumman the B-21 contract, which includes a base contract for engineering and manufacturing development (EMD) and five low-rate initial production (LRIP) options for a baseline total of 21 aircraft… During the fourth quarter of 2023, we recognized a projected loss of $1.56 billion across the five LRIP options. During the first quarter of 2025, we recognized an additional $477 million loss across the five LRIP options. During the fourth quarter of 2025, we again reviewed our estimated profitability on the LRIP phase of the program and made no significant changes to the previously recognized loss."

The LRIP options are "largely fixed price" while the original EMD phase is cost-type. The company now faces the challenge of expanding production capacity while carrying a cumulative $2.04 billion in recognized losses on the program. The 10-K notes "We are in discussions with the U.S. Air Force regarding the potential for an accelerated production rate on the program" — any acceleration would require further investment but could generate improved returns on the NTE phase (lots up to unit 40). For now, the B-21 is the single largest drag on Aeronautics Systems operating income.

Financial Performance: Modest Growth, B-21 Distortion

From the Consolidated Statements of Earnings:

The dramatic 103% jump in net earnings from 2023 to 2024 is not organic growth — it is the non-repeat of the $1.56 billion B-21 loss provision. The MD&A explains 2025 growth: "2025 sales increased $921 million, or 2 percent, due to higher sales of $1.1 billion at Mission Systems, $603 million at Defense Systems… and $596 million at Aeronautics Systems. These increases were partially offset by $960 million of lower sales at Space Systems, largely due to a $738 million sales reduction associated with wind-down of work on the restricted space and NGI programs."

Operating income drivers: per MD&A, 2025 operating income benefited from "a $231 million pre-tax gain on sale for the training services divestiture and a $218 million increase in the FAS/CAS operating adjustment," partially offset by "a $167 million decrease in segment operating income, primarily driven by $423 million of lower operating income at Aeronautics Systems reflecting the first quarter B-21 loss provision."

Pension MTM benefit: Net earnings include a $527M pre-tax mark-to-market pension benefit (vs $443M in FY2024), driven by "actual net plan asset returns of 11.3 percent compared to our 7.5 percent asset return assumption." Stripping MTM out, MTM-adjusted net earnings were $3,788M in 2025 vs $3,842M in 2024 — essentially flat.

Cash Flow: The Quiet Strength

From the Consolidated Statements of Cash Flows:

Per MD&A: "2025 free cash flow increased $686 million, or 26 percent, due to higher net cash provided by operating activities as well as lower capital expenditures." CapEx declined from $1,775M in 2023 to $1,450M in 2025 — an 18% reduction as major Space Systems restricted-program capacity build-outs tapered. The company "returned $2.9 billion in cash to shareholders through share repurchases and dividends" in 2025.

CFFO/NI of 1.14 in 2025 and 1.05 in 2024 both exceed 1.0. The 2023 ratio of 1.88 is inflated because earnings were depressed by the B-21 loss (a non-cash accrual) while cash kept flowing — exactly the opposite of a manipulation signal.

Balance Sheet: The Leverage Concern

From the Consolidated Statements of Financial Position:

Goodwill at $17.4B is 105% of equity. This is the legacy of the 2018 Orbital ATK acquisition, the 2001 Litton + Newport News Shipbuilding acquisitions, the 2002 TRW acquisition, and the 1996 Westinghouse defense and electronics deal. The 10-K lists all of these in its history section. While NOC has not taken a goodwill impairment in FY2025 (goodwill decreased only slightly, from $17,512M to $17,437M, reflecting the training services divestiture), the coverage ratio means that any future impairment would directly destroy equity.

Cash of $4.4B covers only 26% of $17.0B total debt. Of the $4.4B cash, only "$265 million was held outside of the U.S. by foreign subsidiaries," per MD&A. The MD&A notes: "In May 2025, we issued $1.0 billion of unsecured senior notes for general corporate purposes, including debt repayment, share repurchases and working capital." Debt is rising; share repurchases are being funded with debt issuance rather than organic cash.

Debt/EBITDA is 2.4x — healthy. Interest coverage of 6.4x shows plenty of room to service debt. So the D2 leverage check passes, but C4 cash-to-debt fails because cash is deliberately being returned to shareholders rather than accumulated on the balance sheet.

Backlog: The Forward Story

Backlog at December 31, 2025 was $95.7 billion, up 5% YoY:

2025 net awards totaled $46.3 billion, including $14.8 billion for restricted programs, $3.3 billion for F-35, $2.5 billion for GEM 63 and $1.3 billion for Virginia Class submarines. Backlog is 2.3x annual revenue — strong forward visibility. The 9% decline in Aeronautics backlog warrants tracking; the B-21 is in Aeronautics and book-to-bill matters.

The 18-Point Screening

Revenue Quality

DSO of 12 days is among the lowest in the S&P 500 because NOC's counterparty is the U.S. government, which pays on schedule. Unbilled receivables of $6.5B (from long-term contract cost-to-cost accounting) are not included in DSO — they represent work performed but not yet billable per contract milestones.

Expense Quality

Inventory decline reflects the conversion of long-term contract costs into cost of sales.

Cash Flow Quality

Balance Sheet

Acquisition Risk

Manipulation Score

Components: DSRI 1.057, GMI 1.028, AQI 0.981, SGI 1.022, DEPI 0.973, SGAI 0.988, TATA -0.0112, LVGI 0.968. All components are benign. SGI of 1.022 (2.2% revenue growth) matches reported revenue growth exactly — no hidden inflation. TATA of -0.0112 shows total accruals are net negative, meaning cash conversion exceeds reported earnings.

Key Risks from the 10-K

1. Sole Customer Concentration

From Item 1A: "Our primary customer is the U.S. government, from which we derived 84 percent of our sales in 2025. We have a number of large programs with the DoW, in particular. The U.S. government has the ability to delay, modify or cancel ongoing competitions, procurements and programs, and change its acquisition strategies."

2. Government Shutdown and Continuing Resolution

From MD&A: "Annual appropriations to fund the federal government for FY 2026 have not yet been enacted. On October 1, 2025, the U.S. Government entered a shutdown, which ended on November 12, 2025. The federal government is currently operating under a continuing resolution ( CR ) that extends funding for most agencies (including DoW) until January 30, 2026." A prolonged CR or shutdown "could lead to program cancellations, disruptions and/or stop work orders."

3. Fixed-Price Contract Cost Growth — The B-21 Precedent

From Item 1A: "Fixed-price contracts tend to have more financial risk than cost-type contracts, including as a result of inflationary pressures, labor rates and shortages, challenges in estimating contract revenues and costs, and supplier challenges. In 2025, approximately half of our sales were derived from fixed-price contracts."

The B-21 LRIP losses of $1.56B (Q4 2023) and $477M (Q1 2025) demonstrate this is not a hypothetical risk — cumulative recognized losses now total $2.04B on a single program. The risk factors warn: "If we do not achieve our estimates or meet terms in our contracts, our profitability has at times been, and may be, reduced, and we have incurred and may incur losses."

4. Nunn-McCurdy Act Risk

From Item 1A: "if program costs exceed certain thresholds, or if programs are behind schedule, our U.S. government customer has been, and may in the future be, required to provide congressional notification of significant or critical cost increases or noncompliance with contractual cost or schedule provisions under the Nunn-McCurdy Act, which, in some circumstances, could result in program restructure or termination."

5. Executive Order Restrictions on Capital Deployment

From Item 1A: "The U.S. government can also introduce new contract terms that could impact and/or restrict our capital deployment strategy under certain circumstances related to contractor underperformance, noncompliance, insufficient prioritization of a particular contract, insufficient investment or insufficient production speed. If our contracts with the U.S. government include such terms and we are determined to have triggered any of the foregoing circumstances, we may be prohibited from engaging in share repurchases or dividends for a period of time."

This is a novel risk — the Administration has issued executive orders specifically targeting contractor "incentive compensation metrics" and production speed. Given NOC returns 70%+ of FCF to shareholders, any EO-driven limit on buybacks and dividends would materially change capital deployment.

6. Tariff and Macroeconomic Exposure

From MD&A: "Economic tensions and changes in international trade policies, including, for example, the widespread tariffs announced since last year by the U.S. on its major trading partners… could also further impact the global market for defense products." The company states it does "not believe that the tariffs in effect at this time will have a material adverse effect" but flags continuing uncertainty.

7. Contract Loss Exposure on Other Programs

The critical audit matter identified by Deloitte focused on "Revenue Recognition — Estimates of Revenue and Cost at Completion for Select Long-Term Contracts." Deloitte stated that it "analyzed the Company s contract portfolio to identify contracts that we believe had elevated financial or performance risk." The B-21 is the known example; what other programs are on Deloitte's elevated-risk list is not disclosed.

Summary

Grade: F. The grade reflects the critical-fail on cash-to-debt (C4), a critical check in our framework, plus the goodwill overhang. The operating quality is otherwise strong.

Northrop Grumman is a pure-play defense prime with a $95.7 billion backlog — 2.3x annual revenue — giving exceptional forward visibility. The B-21 losses are real but now appear contained: after the Q1 2025 $477M top-up, the Q4 2025 review resulted in "no significant changes to the previously recognized loss." Revenue quality is pristine (DSO 12 days, accruals -1.1%, M-Score -2.44). FCF grew 26% to $3.3B.

The F grade is not about earnings manipulation — it's about capital structure. NOC has chosen to return cash aggressively to shareholders ($2.9B in 2025) while running with $17.0B of debt and $17.4B of goodwill against $16.7B of equity. The May 2025 $1.0B bond issuance to fund buybacks is a warning sign. If a future B-21-style loss hits a different program, if the Administration's executive orders restrict buybacks, or if DoW budget pressure forces a goodwill impairment on the Orbital ATK-era assets, the equity cushion could thin rapidly.

The key question for investors: Is 84% U.S. government concentration an asset (visible backlog) or a liability (monopsony risk)? The answer depends on how the FY2026 appropriations cycle, the B-21 production ramp, and any further executive orders unfold over 2026.
