The $60M Gap in Karman Holdings' Growth Story (KRMN)

"Record quarterly revenue." "Record quarterly net income." "Record full-year revenue." Karman Holdings' earnings release uses the word "record" seven times to describe FY2025 — the defense subsystem maker's first full year as a public company, during which revenue hit $471.5 million on the strength of missile defense, space launch, and hypersonic weapons programs. Nine days later, the 10-K landed. It shows $42.5 million in negative free cash flow and $156 million in unbilled work piling up behind those records.

The gap between what KRMN earned on paper and what it collected in cash is $60 million. Contract assets — revenue recognized but not yet billed — grew 46% to $156.3 million, outpacing the 36.6% revenue growth. SG&A nearly doubled to $85.7 million as the company absorbed IPO costs, three acquisitions, and its first year of public-company overhead. Behind a $550.6 million backlog and guided 53% revenue growth for FY2026, the question isn't whether Karman is growing. It's whether this growth model can ever produce cash — and whether the 562x earnings multiple gives it enough runway to prove it.

The Cash Conversion Puzzle

Karman Holdings reported $17.4 million in net income for FY2025. That sounds profitable until you check the cash flow statement: operating cash flow was negative $22.1 million, and after $20.3 million in capital expenditures, free cash flow came in at negative $42.5 million. The distance between reported earnings and cash generation is the single most important number in this filing.

The mechanism isn't hidden — it's sitting in the accounting policies footnote. Contract assets, which represent revenue KRMN has recognized on long-duration government contracts but hasn't yet billed, grew from $107.2 million to $156.3 million. That 46% increase means the company added $49.1 million in unbilled work during a year when revenue grew 36.6%. Add the $78.7 million in traditional accounts receivable, and 49.8% of KRMN's annual revenue — nearly half — exists as work performed but cash not yet collected.

The bridge tells a clear story: $50.8 million in non-cash add-backs (depreciation plus stock compensation) should have created a comfortable cash cushion above net income. Instead, $49.1 million in contract asset growth alone consumed nearly all of it, and additional working capital drains pushed operating cash flow deep into negative territory.

There's a subtlety in the net income figure itself. The filing discloses a $4.1 million write-off of a contingent consideration liability — a prior acquisition's earnout that wasn't met. That non-cash gain boosted net income by roughly $3.0 million after tax. Strip it out, and real earnings power is closer to $14.4 million against negative $42.5 million in cash outflow. The gap widens.

"As of December 31, 2025, the Company had $550.6 million of remaining performance obligations under its existing contracts at such time. The Company expects to recognize approximately 73.5% of the remaining performance obligations as revenue in 2026, 17.0% in 2027, and 9.5% thereafter."

The remaining performance obligations provide some comfort: $550.6 million in contracted backlog, with $404.7 million expected in 2026. But KRMN guided FY2026 revenue of $715 to $730 million, which means $310 to $325 million of that target depends on new orders. The backlog covers roughly 56% of the guided revenue — meaningful but not sufficient. And backlog converting to revenue doesn't automatically mean backlog converting to cash. Karman Holdings generated $17.4 million in net income in FY2025 but burned $42.5 million in free cash flow, a $60 million gap driven by $156 million in unbilled contract assets that grew 46% faster than revenue.

The $85M Question

The second line of scrutiny falls on selling, general, and administrative expenses, which surged 93% from $44.4 million to $85.7 million. Revenue grew 36.6%. SG&A grew 2.5 times faster. The ratio jumped from 12.9% to 18.2% of revenue — a 530 basis point expansion that consumed the entire 270 basis point gross margin improvement and then some.

The headline is alarming, but the composition matters more than the total. The 10-K's segment footnote decomposes part of the answer.

"General and administrative expenses include share-based compensation of $8.1 million, $1.0 million and $1.3 million for the years ended December 31, 2025, 2024 and 2023, respectively."

Stock-based compensation jumped from $1.0 million to $8.1 million — a $7.1 million increase tied to IPO equity grants. This accounts for 17.2% of the total SG&A increase and is largely non-recurring as the initial grant pool amortizes. The remaining $34.1 million increase reflects higher professional fees from operating as a public company and integrating three acquisitions: SOX compliance, audit and legal costs, new corporate headcount, and integration expenses. The critical question is how much of this $34.1 million is permanent infrastructure versus transitional overhead.

The margin impact extends further. Acquisition-related intangible amortization of $31.4 million sits below gross profit, directly depressing reported operating margin. This is a non-cash charge from purchase price allocation on KRMN's eight acquired businesses. Exclude it, and adjusted operating margin is 22.1% — meaningfully closer to industrial peers and a fundamentally different picture than the reported 15.5%.

The pre-IPO SG&A baseline of roughly 13% of revenue provides the benchmark. If SG&A normalizes toward 14% to 15% of revenue as IPO costs roll off and acquisition integration matures, the operating leverage story becomes real — adjusted operating income would approach $100 million on guided 2026 revenue. If SG&A stays above 17%, the overhead is structural, and the operating leverage thesis that supports the valuation fails. KRMN's selling and administrative expenses surged 93% to $85.7 million in FY2025, with $7.1 million in stock compensation and $34.1 million in public company overhead consuming the entire 270-basis-point gross margin expansion.

Debt That's Better Than It Looks

The headline debt figures look precarious: $499 million in notes payable, $580.5 million including finance leases, 4.02x Net Debt/EBITDA, and negative free cash flow. For a company that IPO'd 14 months ago, the leverage appears aggressive. The filing's debt footnotes tell a more nuanced story.

"The Citi Term Note carries variable interest payments based on specified benchmark reference rates. Interest rates were 7.50% and 11.01% as of December 31, 2025 and 2024, respectively."

KRMN refinanced from TCW to Citi during 2025, cutting its interest rate by 351 basis points. The result is counterintuitive: interest expense actually fell from $50.9 million to $45.2 million despite the company adding $170 million in new debt to fund three acquisitions (MTI for an undisclosed amount, ISP for $75 million in incremental term loan, and Five Axis for $130 million). Interest coverage improved from 1.25x to 1.64x — still thin by industrial standards, but trending in the right direction.

The maturity structure provides additional breathing room. Only $5.05 million per year is due from 2026 through 2030 — essentially token amortization. The real maturity wall is a $481.5 million bullet payment in April 2032, six years away.

"2026: $5,050 | 2027: $5,050 | 2028: $5,050 | 2029: $5,050 | 2030: $5,050 | Thereafter: $481,517 | Total: $506,767"

The springing financial covenant — a 6.50x Consolidated First Lien Net Leverage Ratio test — only activates if the revolver is drawn past a threshold. At roughly 4.0x actual leverage, KRMN has substantial headroom. The OBBBA's increased interest deduction limit to 30% of EBITDA also helps; with KRMN's interest-to-EBITDA at 38.6%, the higher threshold captures more of the deduction than the prior 163(j) limit would have allowed.

The risk isn't near-term refinancing or covenant breach. It's whether Karman can generate enough cash organically to avoid needing additional debt for its next acquisition. The February 2026 Seemann/MSC deal suggests the answer, at least for now, is no. Karman Holdings' interest expense fell from $50.9 million to $45.2 million in FY2025 despite adding $170 million in new debt, because a refinancing reduced the interest rate from 11.01% to 7.50%.

One Customer, Many Programs

Karman's S-1 and earnings materials emphasize a reassuring framing: "over 130 active programs" with no single program exceeding 12% of revenue. That's genuine program-level diversification. The 10-K, however, reveals the customer-level picture is less comforting.

"For the year ended December 31, 2025, the Company had three customers with greater than 10% of the Company's revenues, these customers comprised 28.5%, 12.8% and 10.2% of the Company's total revenues during the year."

Three customers account for 51.5% of revenue. More importantly, the trend shows the top customer's share growing — from 23.5% in FY2023 to 27.8% in FY2024 to 28.5% in FY2025. While customers two and three are diversifying away, customer one is becoming more entrenched.

"We estimate that no single program accounted for more than 12% of sales in the twelve months ended December 31, 2025 or the twelve months ended December 31, 2024, with revenue from over 130 active programs."

The distinction matters: 130 programs spread across three prime defense customers is fundamentally different risk than 130 programs spread across thirty. A single prime contractor's budget decision, program delay, or competitive loss could affect a quarter of KRMN's revenue regardless of how many individual programs that customer funds.

The end-market revenue mix adds another dimension. Tactical Missiles and Integrated Defense — covering counter-UAS systems, loitering munitions, and precision-guided weapons — grew 48.5% year-over-year to $171.7 million, far outpacing Hypersonics (30.9%) and Space and Launch (30.2%). Over two years, Tactical Missiles went from the smallest segment at 30.6% to the largest at 36.4%.

This mix shift toward Tactical Missiles is a positive growth signal — it aligns with DoD's accelerating counter-UAS and loitering munition budgets. But it likely deepens the customer concentration problem, since these programs are overwhelmingly procured through the same prime contractors that already dominate KRMN's revenue. The supplier side compounds the risk: one supplier now accounts for 23.8% of accounts payable, up from 19.6% in FY2024. KRMN's top customer grew from 23.5% to 28.5% of revenue over three years while the company's Tactical Missiles segment surged 48.5%, creating deepening concentration risk behind the "130 programs" diversification claim.

The Acquisition Lifecycle Test

Karman's financial profile — rapid revenue growth, negative free cash flow, rising leverage, surging overhead — isn't unusual in isolation. It's the signature of a company in the integration phase of an acquisitive growth strategy. The investment question is whether this phase resolves into cash generation or becomes a permanent condition.

A useful framework maps acquisitive industrials through four phases: Deploy (acquiring companies, debt rises), Integrate (SG&A surges, working capital builds, margins compress), Convert (FCF inflects positive, overhead normalizes, receivables become cash), and Compound (cash funds further acquisitions and capital returns, leverage declines). KRMN's financial data places it squarely in Phase 2.

The evidence is unambiguous. Investing cash flow of negative $238 million in FY2025 confirms deployment is active. SG&A at 18.2% of revenue (up from 12.9%) confirms integration costs are running. Contract assets growing 46% while gross margins expand from 37.6% to 40.3% shows the acquired businesses are operationally productive — they just haven't converted that productivity into cash.

Curtiss-Wright (CW) demonstrates what Phase 4 looks like. CW also pursues acquisition-driven defense growth — revenue grew 115% in its most recent year — but it generates 33.3% free cash flow margins, returned $430 million to shareholders through buybacks in H2 2025, and carries only 0.38x debt-to-equity. CW's debt of $957.5 million is nearly double KRMN's, but on $3.5 billion in revenue its debt-to-revenue ratio is 0.27x versus KRMN's 1.06x. CW's debt is proportionate to its cash generation; KRMN's is proportionate to its ambition.

At roughly $73 per share, KRMN's $9.7 billion market cap implies the market expects roughly $1.6 billion in revenue with 14% net margins within three to five years. That requires a 29% revenue CAGR (FY2025's 36.6% growth was acquisition-boosted) plus a near-quadrupling of net margins. To trade at CW's 42.6x P/E on guided FY2026 revenue with CW-like margins, net income would need to reach $101 million — a 5.8x increase from today's $17.4 million.

The circular dependency is the core risk: achieving defense-peer margins requires SG&A normalization plus interest expense reduction, which requires cash generation, which requires contract asset conversion, which takes time the debt load may not afford. The valuation assumes this entire chain resolves favorably. Three metrics in the Q1 2026 10-Q will signal whether the transition from Phase 2 to Phase 3 is approaching.

If SG&A falls below 16% of revenue while contract assets stabilize or decline, the operating leverage inflection is real and the transition to cash generation becomes plausible within 12 to 18 months. If SG&A stays above 17% and contract assets keep climbing, the overhead is structural and the cash conversion timeline extends beyond what a 562x P/E can reasonably accommodate. The Seemann/MSC acquisition in February 2026 adds a complication: if it brings significant new integration costs, it may reset the clock to Phase 1 before Phase 2 completes. Karman Holdings trades at 562x earnings while peer Curtiss-Wright generates 33% free cash flow margins at the same acquisition-driven growth model, illustrating the two-phase gap between KRMN's current integration stage and cash-compounding maturity.

Frequently Asked Questions

What does Karman Holdings (KRMN) actually do?

Karman Holdings designs, manufactures, and tests mission-critical subsystems for U.S. missile defense, space launch, and hypersonic weapons programs. Operating through eight subsidiaries including AAE Aerospace, AEC, AMRO, Systima, and three FY2025 acquisitions (MTI, ISP, Five Axis), the company serves as a Tier 2/3 defense subcontractor to prime contractors. Revenue comes from 130+ active programs across three end markets: Tactical Missiles and Integrated Defense (36.4% of FY2025 revenue), Hypersonics and Strategic Missile Defense (31.8%), and Space and Launch (31.8%).

Why is KRMN's free cash flow negative despite record revenue?

The primary driver is a $49.1 million buildup in contract assets (unbilled revenue), which grew from $107.2 million to $156.3 million in FY2025. KRMN recognizes revenue as it performs work on government contracts, but billing and cash collection lag behind. Combined with $78.7 million in accounts receivable, 49.8% of annual revenue is tied up as work completed but not yet collected. Additional drains include $20.3 million in capex and $85.7 million in SG&A (up 93%). The result: $17.4 million in net income but negative $42.5 million in free cash flow.

How much debt does Karman Holdings carry?

Total notes payable are $499.1 million, but total obligations including $81.4 million in finance leases reach $580.5 million. The maturity schedule is heavily back-loaded: only $5.05 million per year is due from 2026 through 2030, with $481.5 million due in a bullet maturity in April 2032. The interest rate on the Citi Term Note is 7.50%, down from 11.01% after a 2025 refinancing. Despite $170 million more debt than FY2024, interest expense declined from $50.9 million to $45.2 million. Net Debt/EBITDA is 4.02x.

Who are KRMN's biggest customers?

Three customers accounted for 51.5% of FY2025 revenue at 28.5%, 12.8%, and 10.2% respectively. The top customer's share has grown from 23.5% in FY2023 to 28.5% in FY2025, while the second and third customers declined. No individual program exceeds 12% of revenue across 130+ active programs, but customer-level concentration is distinct from program-level diversification. Substantially all customers are U.S. government or commercial enterprises.

What are remaining performance obligations and why do they matter?

Remaining performance obligations (RPO) represent contracted revenue not yet recognized. As of December 31, 2025, KRMN had $550.6 million in RPO, with 73.5% ($404.7 million) expected in 2026, 17.0% in 2027, and 9.5% thereafter. KRMN guided FY2026 revenue of $715 to $730 million, meaning $310 to $325 million depends on new orders beyond existing RPO.

How does KRMN compare to Curtiss-Wright (CW)?

CW is the most instructive peer because it shares KRMN's defense exposure and acquisitive model but is further along the lifecycle. CW generates 33.3% FCF margins versus KRMN's negative 9.0%, 13.8% net margins versus 3.7%, and carries 0.38x debt-to-equity versus 1.30x. CW returned $430 million via buybacks in H2 2025 while KRMN returned zero. CW trades at 42.6x P/E versus KRMN's 562.8x. The divergence illustrates KRMN is in an earlier acquisition lifecycle phase.

What caused the SG&A surge in FY2025?

SG&A grew 93% from $44.4 million to $85.7 million. The increase decomposes into $7.1 million in stock-based compensation (jumping from $1.0 million due to IPO equity grants) and approximately $34.1 million in public company and acquisition overhead including SOX compliance, audit and legal fees, and integration expenses. Pre-IPO SG&A averaged 13% of revenue and rose to 18.2%. Whether this normalizes determines the forward margin trajectory.

Is the material weakness resolved?

Yes. KRMN reported material weaknesses in its Q2 and Q3 2025 10-Q filings, standard for a January 2025 IPO building reporting infrastructure. The FY2025 10-K is the first clean annual filing. The remediation coincided with conversion from LLC to C-corp, implementation of OBBBA tax provisions, and hiring of corporate staff reflected in the SG&A increase.

What is the Tactical Missiles growth story?

Tactical Missiles and Integrated Defense grew 48.5% year-over-year from $115.6 million to $171.7 million, outpacing Hypersonics at 30.9% and Space and Launch at 30.2%. Over two years it grew from 30.6% to 36.4% of total revenue, becoming KRMN's largest end market. This aligns with DoD's increased counter-UAS and loitering munition procurement.

What should investors watch in the next filing?

Three metrics in the Q1 2026 10-Q: SG&A as a percentage of revenue (below 16% signals normalization, above 17% signals structural overhead), contract assets (below $140 million with quarterly revenue above $175 million means cash conversion is improving), and Seemann/MSC acquisition details (purchase price and incremental debt will reveal whether KRMN re-entered the deployment phase before completing integration).

Is KRMN's 562x P/E justified?

At current prices, the valuation implies roughly tripling revenue to approximately $1.6 billion with 14% net margins within 3 to 5 years. To trade at CW's 42.6x P/E with CW-like margins on guided FY2026 revenue, net income would need to reach $101 million — a 5.8x increase from $17.4 million. Revenue growth supports the top line, but margin expansion requires resolving the cash conversion problem first.

How does OBBBA affect KRMN?

The One Big Beautiful Bill Act (signed July 4, 2025) benefits KRMN through 100% bonus depreciation on $20.3 million in capex, an increased interest deduction limit to 30% of EBITDA (directly helpful since KRMN's interest-to-EBITDA ratio is 38.6%), and immediate R&D expensing. The filing confirms income tax liability decreased from accelerated deductions.

Methodology

Data Sources

This analysis draws on multiple layers of filing data processed through the MetricDuck automated pipeline:

• XBRL financial data: Three years of annual income statement, balance sheet, and cash flow data for KRMN, extracted from SEC EDGAR XBRL filings via MetricDuck's metrics processor. Peer financials (CW, HUBB, DOV, LII) sourced through the same pipeline.
• Filing intelligence signals: Automated extraction from KRMN's 10-K FY2025 (filed April 3, 2026), including management tone analysis, risk factor severity, customer concentration flags, and debt profile assessment.
• Filing text sections: Direct reading of MD&A (results of operations, liquidity), risk factors, and footnotes covering debt, segments, accounting policies, and commitments from the KRMN FY2025 10-K.
• Filing change analysis: Signal comparison across Q2 2025 10-Q, Q3 2025 10-Q, and FY2025 10-K filings to track material weakness remediation and tone shifts.
• Peer benchmarking: 15-metric comparison of KRMN against HUBB, DOV, LII, and CW using MetricDuck's company comparison tools.
• Derived calculations: 40+ calculations covering SG&A decomposition, adjusted margins, contract asset ratios, interest coverage, RPO conversion, and valuation scenarios, each documented with source formulas.

Limitations

• Peer set mismatch: Assigned peers (HUBB, DOV, LII, CW) are broad industrials. Only CW has meaningful defense subsystem overlap. Pure defense subcontractor peers (KTOS, MRCY) would provide tighter comparisons but are not in the assigned set.
• Single segment reporting: KRMN reports as one consolidated segment. We cannot assess which of the eight acquired businesses drives margin or growth. Division-level acquisition ROI is not determinable.
• Pre-IPO comparability: FY2023 and FY2024 data are pre-IPO (LLC structure). Capital structure, tax treatment, and SG&A levels are structurally different, limiting year-over-year margin comparisons across the IPO boundary.
• Organic vs. inorganic growth unknown: The 36.6% revenue growth includes contributions from MTI, ISP, and Five Axis acquisitions. Organic growth rate is not separable from the filing, making it difficult to assess platform growth independent of acquisitions.
• R&D spending not separately reported: R&D expenses show as N/A across all periods. For a defense technology company this is unusual — R&D is likely embedded in COGS as customer-funded development.
• LII filing intelligence unavailable: The filing index request for LII returned a server error, limiting the qualitative signal comparison to three of four peers.
