Karman Holdings Inc. (KRMN) stock intrinsic value fair value estimate & owner earnings analysis

Karman Space & Defense makes the hard-to-build structural parts of missiles, hypersonic vehicles and space launchers: composite payload fairings and protection systems, aerodynamic interstages, solid-rocket-motor components and ablative heat shields. It sits one tier below the prime contractors, on more than 130 programs, and its revenue in 2025 split roughly evenly between Hypersonics & Strategic Missile Defense, Tactical Missiles & Integrated Defense Systems, and Space & Launch. In February 2026 it added Seemann Composites and Materials Sciences ($210 million cash plus $10 million of stock), which created a fourth leg, Maritime Defense (submarine and naval composites, 18% of second-quarter revenue). It has also signed to buy Walker Precision Engineering of Glasgow for about $94 million, its first European business. The company was assembled by a private-equity sponsor from 2020 and listed in February 2025. Earnings level. Revenue grew from $226 million (2022) to $472 million (2025). Owner earnings, meaning operating cash flow with working-capital swings removed, less stock compensation and the capex needed to maintain the business, were about -$7 million, $10 million, $24 million and $57 million over 2022-2025. That is -$0.05, $0.06, $0.15 and $0.43 per share. Because the company carries heavy debt, we value the business before its lenders: adding back cash interest of $36 to $48 million a year gives business cash flow of $28, $56, $72 and $102 million. Two accounting points matter. First, operating cash flow was negative in 2025 (-$22 million) only because $93 million went into working capital: contract assets rose $49 million as programs ramped, and $12 million of acquisition-related accruals were paid. We removed that timing effect rather than treating the negative figure as the run rate. Second, about $23 million a year of amortization on acquired intangibles is added back, because it is a non-cash charge for past purchases. Those acquired customer relationships do wear out, so we do not let earnings grow forever. After the second year, growth in every case comes only from contracted work and named capacity. Stock compensation is small: $1.4 million in both 2025 and the first half of 2026. A one-time $6.6 million cash payout of IPO phantom units in 2025 is already inside cash flow. Our anchor is 2025 business cash flow of about $102 million. The history is short and the business changed a lot through acquisitions, so we lean on the most recent year rather than a longer median. Business cash flow grew 41% in 2025. In the base case we assume about $128 million in 2026, a lower growth rate (+26%). The evidence: first-half 2026 revenue rose 55% to $333 million, Seemann added a full business, and backlog reached a record $1.3 billion in June 2026, up 65% from year-end. Operating cash flow was still slightly negative in the first half (-$3 million) because receivables and contract assets keep growing. That is why we credit cash flow below what reported earnings would suggest. Debt. At June 30, 2026 the company owed $757 million on its Citibank term loan (repriced in February 2026 to SOFR + 2.75%, maturing April 2032) and $102 million of finance leases. Adding the $94 million committed for Walker and subtracting about $30 million of cash beyond operating needs gives net debt of about $923 million, or roughly $7 a share. The loan's cost is close to our 6% yardstick, so we made no adjustment for it. The only financial covenant is a springing 6.5x first-lien net leverage test, which applies only if the revolver is drawn. Management states leverage of about 3.7x, so there is room. Base case: business cash flow of $128 million in 2026 and $148 million in 2027 as the $1.3 billion backlog, the full year of Seemann and the Walker purchase come through. After that it stays flat. We credit no further acquisitions and no market growth, because new deals are bets rather than a proven, self-funded routine, and the wasting acquired intangibles argue against assuming automatic growth. The business is worth about $2.45 billion, owes about $0.92 billion, and the difference is about $11.50 per share. Bear case: the 2026-27 ramp happens ($122 million, then $135 million), but then defense procurement falls the way it did in the 2011-2015 sequestration period, when U.S. procurement budgets dropped roughly 20-30% over several years. With three customers making up 51.5% of 2025 revenue, a program cancellation or a delayed launch would hit hard. Business cash flow falls to about $82 million by 2030, recovers to about $105 million, and then fades 2% a year as acquired programs age. Even at the trough it covers interest of roughly $55-60 million, so the 2032 term loan would likely be refinanced, though at higher leverage. The business is worth about $1.50 billion, owes about $0.92 billion, and the difference is about $4.33 per share. Bull case: the levers already in place work. The 200,000 square foot Salt Lake City factory starts production in the fourth quarter of 2026, a five-year Space & Launch long-term agreement has already become a firm order, and three more contingent supply agreements firm up. Business cash flow reaches about $155 million in 2027 and grows about 5% a year to around $190 million by 2031, then rises only slightly. The business is worth about $3.10 billion, owes about $0.92 billion, and the difference is about $16.40 per share. In the first half of 2026 operating cash flow again fell short of reported earnings, which tested the base case. The cause is the growth of receivables and contract assets, the same pattern as 2025, and not losses or write-offs. Management's own target is cash conversion of only 80-90% of net income during the build-out. We therefore kept the level of the cases below the company's adjusted EBITDA guidance of $215-222 million, which adds back items we count as costs. Our previous estimates were built on a different basis and are not comparable. The main business change since then is the Seemann acquisition, the larger backlog and the signed Walker deal. All of these were bought with more debt, which offsets much of their value per share. Margin-of-safety price. We are only moderately sure of the earnings level: there are four years of history, owner earnings turned clearly positive only in 2025, and working capital has absorbed cash every year. The worst plausible outcomes are a defense budget squeeze or the loss of one of its three largest customers while the company carries about $0.9 billion of debt. The debt does not mature until 2032 and has only a springing covenant, so the structure would most likely survive, but very little would be left for shareholders. If we are wrong about how well acquisitions hold their value and about working capital, the shares are worth close to the bear case of about $4. The company pays no dividend, so all of the return has to come from the business growing into its debt over perhaps five years. The margin-of-safety price is $4.50, roughly at the bear-case value. If the base case plays out and the debt is gradually repaid, the base case implies the shares more than double over about five years, which meets a 20% annual target. The price is not set higher because the earnings record is too short and the balance sheet too leveraged to rely on the base case.
