Karman Holdings ($KRMN) Stock Hub 2026: the $1.03 Billion Backlog, Leverage After the Acquisitions and What the Next Print Has to Show

01 Second quarter fiscal 2026 results, reported August 6, 2026

Karman reported the quarter ended June 30, 2026 after the close on August 6. Every headline figure in the release was described by the company as a record, and the full-year outlook was raised rather than reaffirmed.

Revenue was $182.1 million, with organic growth of 24.4% year over year and total growth of 58.2% — the gap between the two being the contribution of acquisitions, principally Seemann Composites. Net income was $14.0 million, up 106.1%, giving fully diluted earnings per share of $0.11 against $0.05 in the prior-year quarter. Non-GAAP adjusted EBITDA was $54.6 million, up 54.7%, and adjusted fully diluted earnings per share $0.14 against $0.10.

The backlog is the number with the longest reach. It stood at $1.3 billion at the end of the quarter, up 65% from the end of fiscal 2025 and up roughly 27% from the $1,026.9 million reported at March 31. Bookings in the quarter were nearly $500 million across all end markets, including a large multi-year agreement with a space and launch customer. Chief executive Jon Rambeau said the company is actively negotiating three further long-term defense agreements with a combined potential value of more than $1 billion — a figure that is a negotiation, not a contract, and should be read as such.

Management raised full-year 2026 guidance to $730 million to $745 million in revenue, from $720 million to $735 million, and to $215 million to $222.5 million in adjusted EBITDA, from $208.5 million to $219.5 million. The increase is modest in percentage terms — $10 million at both revenue endpoints — but it moves in the opposite direction from most of this reporting season.

Two corporate actions landed alongside the numbers. Karman agreed to acquire Walker Precision Engineering for approximately $94 million, taking the company into the European defense market for the first time. And on August 3 it signed a Fifth Amendment to its credit agreement, refinancing $763,961,000 of term loans at 50 basis points lower — SOFR plus 2.25% — and cutting the revolving facility rate by 50 basis points at every level of its leverage-based pricing grid, with the highest level set at SOFR plus 2.00%. The company expects annual interest expense to fall by approximately $4 million, which is consistent with the arithmetic: half a point on $764 million is about $3.8 million a year.

That amendment is the fifth in sixteen months, following amendments dated May 27 and October 24, 2025 and February 2 and March 9, 2026, against an original credit agreement of April 1, 2025. A borrower returning to its lenders five times in that span is unusual; a borrower doing so and improving the terms each time is telling you something about how the credit market now views the business. It is also worth noting the direction of travel: this refinancing lowers the cost of debt that was taken on to buy growth, and the debt itself has not gone away.

The demand backdrop the company cites is external and checkable: more than $90 billion in recent prime contractor awards for THAAD and PAC-3 interceptors, and over $76 billion for new Columbia and Virginia class submarines. Karman is a supplier into those programs rather than a prime, so these totals are the size of the pond, not the size of the catch.

The webcast is carried at events.q4inc.com/attendee/435493861 and through the investor section of the company website at investors.karman-sd.com. The named participants are chief executive officer Jon Rambeau, chief financial officer Mike Willis, chief operating officer Jonathan Beaudoin and senior vice president of investor relations Steven Gitlin. An audio replay is archived on the investor relations section afterwards.

Three features raise the stakes on this print. It is the first full quarter under a chief executive who took the job on March 23, 2026; the first in which Seemann Composites and Materials Sciences contribute a complete three months rather than eight weeks; and the first test of the second-half ramp, since reaching the midpoint of full-year revenue guidance requires the remaining three quarters to average about $192 million each against $151.2 million in the first quarter.

02 Executive summary

Karman Holdings, trading as Karman Space and Defense, makes the hardware that sits between a missile or a rocket and the environment it flies through: payload protection and deployment systems, hydro and aerodynamic interstage systems, and propulsion and launch systems. It supplies more than 80 prime contractors across more than 130 programs, and the February 2026 purchase of Seemann Composites and Materials Sciences added a fourth end market, Maritime Defense Systems.

The operating record since the February 2025 initial public offering has been consistent. Revenue rose 36.6% in fiscal 2025 to $471.5 million, adjusted EBITDA rose 36.9% to $145.3 million, and the first quarter of 2026 produced $151.2 million of revenue and $44.8 million of adjusted EBITDA. Backlog has risen in every reported quarter, and full-year guidance was raised three times between October 2025 and May 2026 and never cut.

The tension is not in the operating line. It is in the balance sheet and the register. Total debt stood at $855.5 million at March 31, 2026 against $405.7 million of equity, a ratio of 2.11 times, with a term loan principal of $765.8 million. The register is still unwinding a private-equity structure: 24.15 million shares sold at $49.00 in July 2025, another 14 million at $61.00 at the end of May 2026, and a lock-up over roughly 29% of the shares that expired on July 18, 2026. The stock closed at $50.44 on August 3, 2026, below the last placement price. Alongside that sits a governance file worth weighing: material weaknesses in internal control at both December 31, 2024 and December 31, 2025, disclosure controls judged not effective at March 31, 2026, two consecutive late annual reports, and a change of auditor approved on June 10, 2026.

03 Market Data And Peer Comparison

Price and performance figures below are based on the completed session of Friday, August 7, 2026. Float, ownership, short interest, average volume and the consensus target are from Finviz, pulled on the same date. Company financial figures come from SEC filings and company releases, each carrying its own reference date.

Peer comparison, all figures at the August 7, 2026 close

The float is the detail that separates $KRMN from most of this group. At 92.39 million shares against 132.53 million outstanding, roughly three tenths of the company is not freely traded, a legacy of a recent listing and the associated lock-up arrangements. Short interest is measured against that smaller base.

On analyst coverage the honest position is a narrow one. The consensus target above is a Finviz aggregate of third-party estimates pulled on August 7, 2026. Individual houses, ratings and note dates were not verified for this update, so no coverage table is presented. A consensus figure without named notes behind it is a market-data point, not research, and it is neither a company figure nor a Merlintrader forecast.

04 Verified developments, most recent first

05 The numbers, drawn as bars

Every figure below is taken from a Karman press release, Form 10-Q or Form 10-K. Bar widths are the stated value as a percentage of the largest value in each chart, unless a different scale is named in the caption.

Quarterly revenue, five consecutive quarters

Source: Karman quarterly earnings releases furnished on Form 8-K, August 7 and November 6, 2025, March 25 and May 12, 2026. Five straight sequential increases. Part of the 2026 step is the Seemann and Materials Sciences acquisition, which contributed $26.4 million of Maritime Defense Systems revenue against nothing in the comparable quarter.

Backlog at each quarter end

Source: Karman earnings releases and the Form 10-Q for the quarter ended March 31, 2026. The 2025 mid-year figures were labelled “total funded backlog”; from the fourth quarter of 2025 the company reports “total backlog”, with a 10-Q footnote stating that no historical dollar amounts were changed.

Adjusted EBITDA margin by quarter, and the full-year 2026 outlook

Scale runs from zero to 35%, so small differences are deliberately compressed. Margins are as reported; the 31.2% for the fourth quarter of 2025 is $41.977 million of adjusted EBITDA over $134.492 million of revenue. The final bar is implied by the raised guidance midpoints, $214.0 million on $727.5 million. Adjusted EBITDA is a company-defined non-GAAP measure reconciled in each release.

Annual revenue, 2022 through the 2026 guidance midpoint

Sources: Karman annual filings on EDGAR for 2022 to 2025 and the May 12, 2026 guidance midpoint. The final bar is a company forecast, not an outcome, and implies 54.3% growth on 2025, an unquantified part of which comes from acquisitions rather than organic demand.

Market capitalization divided by last reported annual revenue, against listed peers

Market capitalizations are Finviz data read on August 4, 2026. Revenue is each company’s most recent full fiscal year as filed on Form 10-K and retrieved from SEC company facts: TransDigm $8,831M to September 30, 2025; HEICO $4,485M to October 31, 2025; Curtiss-Wright $3,498M to December 31, 2025; Moog $3,861M to September 27, 2025; Loar $496M to December 31, 2025; Ducommun $825M to December 31, 2025; Karman $471.5M to December 31, 2025. This is an equity-only ratio and ignores net debt, which is proportionally larger at Karman than at most of the group. It is a rough placement, not a valuation conclusion.

06 What Karman actually makes

Karman Holdings Inc. trades as Karman Space and Defense. Its predecessor, TCFIII Spaceco Holdings LLC, was formed in August 2020 and converted into a Delaware corporation for the February 2025 listing. It is headquartered in Huntington Beach, California and had approximately 1,400 employees at December 31, 2025, including about 300 multi-discipline engineers, none represented by labor unions. By July 2026 it described 17 locations across eight U.S. states, with the pending Walker transaction adding a European footprint.

Three product families

• Payload protection and deployment systems. Fairings, shrouds, nose cones, separation systems and deployment mechanisms that shield a warhead, satellite or instrument in flight and then release it. This is the classic Karman product and the reason it sits on so many programs without being the prime.
• Hydro and aerodynamic interstage systems. The load-bearing sections joining stages of a missile or launch vehicle. The hydro qualifier is new and reflects the 2026 move into undersea hardware.
• Propulsion and launch systems. Solid rocket motor components, nozzles, energetic assemblies and launch canisters, including the systems added with Five Axis in October 2025.

Four end markets

Until 2026 there were three. Fiscal 2025 revenue divided almost evenly: 32% Hypersonics and Strategic Missile Defense, 36% Tactical Missiles and Integrated Defense Systems, 32% Space and Launch. On completing the Seemann and Materials Sciences purchase in February 2026, Karman added Maritime Defense Systems, covering submarine, unmanned undersea and surface vessel, landing craft and torpedo work.

Karman is a single reportable segment; the end markets are a revenue disaggregation, not segments with their own margins. Profitability by end market is not published, so a reader cannot tell whether the maritime line dilutes or improves the group margin. The 0.7 point year-on-year fall in adjusted EBITDA margin in the first quarter of 2026 is the only visible clue, and the company attributes it to no single cause.

Customer concentration

Three customers each exceeded 10% of fiscal 2025 revenue, at 28.5%, 12.8% and 10.2%, or 51.5% combined; in fiscal 2024 the split was 27.8%, 11.9% and 11.1%. Two customers were approximately 40.7% of accounts receivable at December 31, 2025 and one supplier 23.8% of accounts payable. Karman does not name them. The counterweight management offers is program diversity: no single program exceeded 12% of sales in fiscal 2025 or 2024, and none exceeded 11% in the first quarter of 2026, across more than 130 active programs and more than 80 customers.

07 The fiscal calendar, stated plainly

There is a persistent confusion around Karman’s reporting periods that is worth settling with the filings rather than repeating. Karman’s fiscal year is the calendar year. The Form 10-K for fiscal 2025 states directly: “Our fiscal year begins on January 1 and ends on December 31 of the same year.” The XBRL cover data on every Form 10-Q carries a fiscal year end of December 31.

No change of fiscal year end appears anywhere in the filing record. The February 2025 offering prospectus presents audited results for the fiscal years ended December 31, 2022, 2023 and 2024; the first 10-K, filed April 10, 2025, covers the year ended December 31, 2024. There is no transition period, no stub year and no Form 10-KT. If a source states that Karman moved its fiscal year end, that is not supported by the company’s SEC filings.

What causes the confusion is labelling. Karman names each quarter by the fiscal year it falls in, so the quarter ended March 31, 2026 is “first quarter fiscal year 2026” and the one due on August 6 is “second quarter fiscal year 2026”. Several comparables do run offset years, which makes the assumption easy: TransDigm closes on September 30, Moog in late September, HEICO on October 31. Karman does not.

08 Financial position and what the next print has to show

Two lines belong together. Gross margin improved by 2.8 percentage points and operating margin by 4.2 points, yet adjusted EBITDA margin fell. The reconciliation explains why: the first quarter of 2025 carried $8.084 million of share-based compensation that was added back, a charge tied to P Units and Phantom Units that vested at the initial public offering and did not recur. Adjust for that and the comparison is less favourable to 2026 than the headline suggests.

Cash flow is the line to watch on August 6. Operating cash flow of $0.209 million on $151.2 million of revenue is not a crisis in a business whose contract assets rose in the quarter, but it means the company generated essentially no cash while paying roughly $12.6 million of net interest. Investing outflows of $217.5 million were almost entirely the $210.2 million cash portion of the Seemann purchase, funded by $260.1 million of net term loan proceeds, leaving capital spending of around $7 million.

What to look for in the second quarter print

• Revenue against about $192 million, the average of the three remaining quarters needed to reach the $727.5 million guidance midpoint. A second quarter materially below that puts the full-year range under pressure.
• Adjusted EBITDA margin against 29.6%. Whether the first-quarter dip was mix, integration cost or a genuine shift in the margin profile as maritime revenue scales.
• Operating cash flow, and how contract assets, which stood at $169.4 million at March 31, behave.
• Backlog against $1,026.9 million. Management said in May that it expected bookings growth “later this year”. The second quarter is the first test of that statement.
• Interest expense and the term loan balance. The rate was 6.42% at March 31, 2026, down from 7.50% at December 31, 2025 after the February repricing.
• Commentary on Walker, which is expected to close in the third quarter with no purchase accounting or guidance revision published so far.
• Remediation of the material weaknesses. The first quarter 10-Q reported no changes in internal control during the period.

09 Guidance, and how many times it has moved

Karman has revised its outlook repeatedly, always upward. The sequence is worth laying out because it is the strongest single piece of evidence for the operating case, and because it also shows how much of the 2026 step-up was added by acquisition rather than by trading.

Three observations follow. Fiscal 2025 finished above the top of the August 2025 range and at the top of the January 2026 range, so the raises were not a game of low bars. The preliminary 2026 outlook given in November 2025, before Seemann was announced, was organic growth of 20% to 25%, against guidance now implying 54.3%; the difference is what the company bought. And the range excludes future acquisitions by its own terms, so a Walker contribution would be incremental rather than already inside it.

Management’s stated basis for confidence is that first quarter revenue plus the portion of backlog expected to convert during 2026 represents about 90% of the increased guidance. At the midpoint that implies roughly $655 million of the $727.5 million is delivered or sitting in backlog, leaving about $73 million to be won and delivered inside the year. That is a high coverage ratio for a company growing this fast, and it is the single most useful number management has published.

10 Capital structure: what the growth was bought with

Karman has funded its expansion with debt, not equity. Since the listing it has sold no shares of its own beyond the 8.4 million at the initial public offering; both secondary offerings were sales by existing holders from which the company received nothing. The share count has therefore stayed at 132,526,299. Leverage has done the work instead.

At March 31, 2026 the term note principal outstanding was $765.8 million at 6.42%, down from 7.50% at December 31, 2025, and the revolver was undrawn. Total debt including $97.7 million of finance lease liabilities was $855.5 million against cash of $73.8 million, so net debt was approximately $781.7 million. Against the $214.0 million midpoint of 2026 adjusted EBITDA guidance that is roughly 3.7 times, or about 3.2 times counting only funded debt net of cash and excluding finance leases. The company discloses that a one point rise in rates would have added approximately $6.3 million to interest expense, against $0.8 million a year earlier.

The credit agreement carries a springing covenant rather than a maintenance covenant: consolidated first lien net leverage of no more than 6.50 to 1.00, tested only if revolving borrowings exceed a threshold at a quarter end. With the revolver undrawn the covenant was not required to be tested, and the company reported compliance with its other covenants. That is borrower-friendly, and it also means the covenant gives little early warning, since it only binds once the revolver is already being used.

11 Funded backlog, ceilings and pipeline: three different numbers

Karman’s communications contain four order-related figures with very different meanings. Conflating them is the most common way this stock gets misread, so each is set out below in the company’s own language.

The definition that quietly changed

Through the third quarter of 2025 Karman reported “total funded backlog”, defined as “the total invoiceable value of existing contracts, less amounts previously invoiced”. From the fourth quarter of 2025 the label became “total backlog”, defined as “the total value or current estimated value of existing contracts”. The fiscal 2025 Form 10-K still qualified this as covering contracts “for which funding is appropriated or otherwise authorized”; the first quarter 2026 Form 10-Q dropped that qualifier and footnoted: “Backlog was previously referred to as funded backlog. No changes were made to the historical dollar amounts presented in the table above.”

The company therefore states explicitly that no historical figures were restated, which is the important part: the sequence from $636.4 million to $1,026.9 million is comparable on its own terms. What changed is the forward definition, which now admits “current estimated value” without an explicit appropriation test. For a supplier whose customers are prime contractors rather than the government directly, that distinction is less stark than it would be for a prime, since a purchase order from a prime is a commercial obligation regardless of the appropriation cycle behind it. It is still a loosening, and whether the gap between backlog growth and revenue growth widens from here is worth tracking.

Four questions separate the categories on any given headline: is a dollar value attached, and is it one funded order or a multi-year aggregate; did Karman itself announce it; is it a ceiling on a vehicle shared with other awardees; and does it appear in backlog at the next quarter end. The $21.3 million MK 54 award passes all four and should show up in second or third quarter backlog. The $151 billion SHIELD ceiling passes none of them as a revenue figure. It is a credential and a channel, and nothing about Karman’s share of it has been disclosed.

12 The acquisition record

Karman was assembled by acquisition and has kept buying since listing: five transactions announced or closed in fifteen months, each funded by incremental term debt.

The consequences run through both statements. Goodwill rose from $352.5 million at December 31, 2025 to $439.2 million at March 31, 2026 and net intangibles from $285.9 million to $400.5 million: together $839.7 million against total assets of $1,417.7 million and equity of $405.7 million, so goodwill and intangibles exceed book equity by roughly two times. Karman tests goodwill annually as of October 1 and reported no impairment in 2025, 2024 or 2023. On the income statement, depreciation and amortization inside operating expenses more than doubled year on year in the first quarter of 2026 to $13.8 million, principally from $125.5 million of Seemann intangibles with weighted average useful lives of 16.8 years. That charge is real for GAAP earnings and added back for adjusted EBITDA, which is one reason the gap between the two measures keeps widening.

13 Governance, controls and management

Material weaknesses in internal control

The June 11, 2026 Form 8-K lists the material weaknesses that existed at both December 31, 2025 and December 31, 2024, previously disclosed in Item 9A of both annual reports and Item 4 of the 2025 quarterly reports. They were entity-level and broad rather than narrow and technical:

• Components of the COSO framework were not fully maintained, spanning the control environment, risk assessment, control activities, information and communication, and monitoring.
• Information technology general controls were not designed and maintained effectively for certain systems supporting key financial reporting processes, including change management, security, operations and system development controls.
• Process-level controls were not designed and maintained effectively for all significant business process cycles.

At March 31, 2026 the principal executive and financial officers concluded that disclosure controls “were not effective at a reasonable assurance level”, and the 10-Q states there were no changes in internal control during the period that materially affected, or were reasonably likely to affect, internal control. Remediation is listed among the company’s own risk factors.

Two related facts belong alongside that. Karman filed a Rule 12b-25 notification of late filing for its annual report in both April 2025 and April 2026, in each case citing the need for additional time to complete audit procedures and filing within the extension window. And as an emerging growth company under the JOBS Act it is not required to have its auditor attest to internal control under Section 404(b). The company expects to lose that status during 2026, which would remove the exemption.

The auditor change

On June 10, 2026 the audit committee appointed PricewaterhouseCoopers for the year ending December 31, 2026 and dismissed Baker Tilly, whose reports on the 2025 and 2024 statements contained no adverse opinion, disclaimer or qualification. The 8-K records no disagreements on accounting principles, disclosure or auditing scope, and identifies the previously disclosed material weaknesses as the only reportable events. Moving from a mid-tier firm to a Big Four firm is the conventional step for a company preparing to exit emerging growth status, and it typically raises both audit cost and scrutiny.

Board and management

Jon Rambeau became chief executive on March 23, 2026. He was previously president of the $8 billion Communications and Spectrum Dominance segment at L3Harris and before that of its $7 billion Integrated Mission Systems segment, following more than 25 years at Lockheed Martin across integrated warfare systems, C6ISR, training and logistics, F-35 international programs and technology transition. Tony Koblinski, chief executive from the 2020 founding through the listing and four acquisitions, retired from the executive role and remains a director. Mike Willis is chief financial officer, Jonathan Beaudoin chief operating officer, and Stefan Knighton joined in June 2026 as first chief information and artificial intelligence officer.

The chairman is David Stinnett, a partner at Trive Capital. The proxy records that after the July 2025 secondary offering Mr Stinnett and fellow director John Hamilton, formerly a Trive vice president, “became independent members of the Board”. The audit committee is chaired by Brian Raduenz alongside Hamilton, Stephen Twitty and Mary Petryszyn, with Hamilton, Raduenz and Twitty each designated an audit committee financial expert. At the April 29, 2026 annual meeting Mr Twitty was re-elected with 18,182,265 votes withheld against 68,186,383 for, roughly 190 times the dissent recorded against the other nominee. The proxy also discloses one Section 16(a) lapse in 2025, late Forms 4 filed by Messrs Hamilton and Stinnett on their July secondary disposals.

14 Ownership, Lock-Ups And Positioning

Karman’s register is the unwinding of a private-equity structure, and the mechanics are unusually well documented. Trive Capital, through TCFIII Spaceco Holdings LLC, controlled the company before the listing; at December 31, 2024 there were 166,737,325 membership units outstanding, converted at the offering on a 0.68-for-1 basis into 112,566,039 shares, with the total including P Units reaching about 123.8 million.

The exit ran in stages. In July 2025 existing holders sold 24,150,000 shares at $49.00, an offering management later described as marking “the effective exit of our private equity sponsor”. Also in July 2025 Trive distributed shares in kind to its limited partners; the May 2026 prospectus supplement records those recipients as holding approximately 29% of the stock. In May 2026 a second offering placed 14,000,000 shares at $61.00 for about $854 million to the sellers, again nothing to the company. The Trive-affiliated vehicle KHIS Custodian LP held 3,942,428 shares, or 2.97%, before that offering.

The lock-up calendar

July 18, 2026 is the most concrete supply event in the file, and it is not a forecast: the restriction expired by its own terms. The prospectus supplement itself warns that substantial sales after the offering, “including additional sales by the selling stockholders or other limited partners or certain senior principals of Trive Capital, could harm the prevailing market price”. The shares fell from $46.17 on July 17 to $44.88 on July 20 and have traded between roughly $45 and $51 since. Whether the released stock has actually been sold is not knowable from public filings unless the holders are affiliates required to report.

Two further points. Karman joined the S&P SmallCap 600 on July 17, one day before the expiry, mechanically creating index demand at the moment supply was released. And short interest at 12.10% of float is by a wide margin the highest in the peer group: TransDigm 1.94%, Curtiss-Wright 1.95%, Moog 2.92%, Ducommun 5.06%, HEICO 6.85%, Loar 7.96%. On a float of roughly 92 million shares against average daily volume of about 3.5 million, that is a crowded position for this sector.

Retail sentiment

Discussion of $KRMN on Stocktwits, Reddit and X clusters around Golden Dome, hypersonics, the munitions build-out and the idea that Karman is a picks-and-shovels supplier to several defense themes at once. Those are the views of non-professional traders, not analyst research, and are useful only for understanding why the shares move on a given day. The Finviz consensus target of $102.00 is an aggregation of sell-side estimates and is likewise not a Merlintrader view.

The block below is a snapshot of the Stocktwits flow, with its date. These are opinions of retail traders and non-professional investors, not analyst research, and they measure attention and how one-sided positioning has become rather than anything about the business.

15 Valuation, on the numbers available

Inputs are stated so the arithmetic can be checked: 132,526,299 shares from the May 2026 prospectus supplement, a closing price of $50.44 on August 3, 2026, total debt of $855.5 million and cash of $73.8 million from the March 31, 2026 balance sheet, fiscal 2025 actuals from the March 25, 2026 release and fiscal 2026 guidance midpoints from the May 12, 2026 release.

Three cautions attach. The debt and cash figures are four months old and predate any Walker payment, which would add roughly $94 million of cash consideration if the deal closes as announced. Adjusted EBITDA is a company-defined measure that adds back share-based compensation, transaction and integration expenses, lender fees and other items management deems non-recurring; on a GAAP basis Karman earned $17.4 million in fiscal 2025, so a trailing price-to-earnings ratio runs into the hundreds and is not a useful comparator. And using a March balance sheet against a full-year forecast flatters the multiple slightly if debt has risen since.

Against listed peers, the equity-only ratio in the bar chart places Karman at the top of the group at 14.5 times last reported revenue, marginally ahead of Loar at 13.6 times and well ahead of HEICO at 9.5 times and TransDigm at 8.4 times. The rejoinder is growth: Karman guides to 54% revenue growth in 2026 against mid-to-high single digits for most of the group. The counter-rejoinder is that much of that growth is bought with debt, that HEICO and TransDigm carry decades of aftermarket margin history, and that Karman’s own preliminary 2026 organic outlook was 20% to 25% before Seemann was added.

16 Catalysts to monitor

Only the first line carries a confirmed date. The rest are conditions rather than appointments.

17 The two cases, stated as fairly as possible

Karman occupies a position that is hard to attack: qualified, often sole-source content on more than 130 programs across missile defense, tactical missiles, hypersonics, space launch and now undersea warfare, sold to more than 80 prime contractors. Requalifying a payload protection system or an interstage is expensive and slow, which is why revenue has compounded from $226 million in 2022 to a guided $727 million midpoint in 2026 without a down quarter, at an adjusted EBITDA margin near 30% throughout, a level normally reserved in this industry for aftermarket businesses. Guidance has been raised at every opportunity and never cut, and management says first quarter revenue plus convertible backlog already covers about 90% of the full-year target. The debt taken on to buy Seemann was repriced 75 basis points lower at the same time it was increased. If the second half delivers the implied ramp and maritime scales at group margins, leverage falls through EBITDA growth rather than repayment.

A large part of the growth was purchased. The preliminary organic outlook for 2026, before Seemann, was 20% to 25% against a guided 54%. Goodwill and intangibles of $839.7 million exceed book equity of $405.7 million by about two times, and each deal was financed with incremental term debt now totalling $765.8 million of principal at a floating 6.42%. Net interest consumed 59% of operating income in the first quarter, operating cash flow was $0.2 million, and adjusted EBITDA margin fell year on year for the first time. Three customers are half of revenue. The company has carried entity-level material weaknesses for two consecutive year-ends, concluded that disclosure controls were not effective at March 31, 2026, reported no change to internal control in the quarter, filed late two years running and has just changed auditor. Meanwhile the register is still clearing: roughly 29% of the stock came out of lock-up on July 18, two further tranches follow, and the last institutional block was placed at $61.00 against a $50.44 close.

18 Scenario framework

These are conditional structures for reading the August 6 print and the rest of the year. They are not forecasts, probabilities or recommendations.

19 Bottom line

Karman is one of the cleaner operating stories in the listed defense supply chain and one of the more complicated equity stories. The operating record needs no interpretation: revenue up 51.0% in the first quarter of 2026, backlog up 61.4%, adjusted EBITDA margin around 30% for five straight quarters, guidance raised three times in seven months and never cut. Few suppliers of this size can show that.

What it does not settle is the price of getting there. Most of the recent growth steps were bought, financed with term debt now carrying $765.8 million of principal at a floating rate, and the resulting amortization and interest are why a company with 42% gross margins turned $151 million of quarterly revenue into $7.8 million of net income and $0.2 million of operating cash. Two years of unremediated material weaknesses, a “not effective” disclosure-controls conclusion at March 31, 2026, two late annual reports and a change of auditor are separate from trading performance, and they are the kind of facts that determine how much credit a market gives to a non-GAAP margin.

August 6 is the first clean read on all of it: a full quarter under a new chief executive, a full quarter of the maritime business, the first test of the second-half ramp the guidance requires, and the first statement published after the July 18 lock-up expiry. The four numbers to write down beforehand are $192 million of revenue, 29.6% adjusted EBITDA margin, $1,026.9 million of backlog and $0.2 million of operating cash flow.
