York Space Systems Inc. (YSS) stock intrinsic value fair value estimate & owner earnings analysis

York Space Systems builds small satellites and satellite buses in Colorado. Its main customer is the U.S. Department of Defense's Space Development Agency (SDA), and it built spacecraft for Tranches 0, 1 and 2 of the SDA's Proliferated Warfighter Space Architecture. One customer provided 96% of revenue in the first half of 2026 and 91% in the second quarter. York listed on the NYSE in January 2026 and has since bought three businesses. It acquired Orbion (electric propulsion) in March for about $75 million, mostly in shares, and Solestial (space solar power) in June for about $72 million, mostly in shares. In July it closed the purchase of ALL.SPACE, a maker of multi-orbit military satellite terminals, for $155 million in cash plus shares, a deal valued at about $355 million. About 137.4 million shares were outstanding in August 2026. Earnings record. Only three audited years exist. Revenue was $238 million in 2023, $254 million in 2024 and $386 million in 2025. We measure owner earnings as operating cash flow, less the swing in working capital, less stock compensation, less the capital spending needed to stay in business. On that basis owner earnings were negative in every year: about -$50 million in 2023, -$76 million in 2024 and -$34 million in 2025, or -$0.52, -$0.80 and -$0.36 per share. Reported operating cash flow swings far more ($16M, +$32M, -$121M) because the SDA pays in large milestone installments. We stripped those timing swings out. Customer prepayments, which stood at $110 million at the end of 2025, have now been almost entirely used up: they were $18 million at June 30, 2026, while unbilled work rose to $115 million. From here York funds its own working capital. Adding back roughly $25-27 million a year of cash interest, the business before its lenders lost about $25 million in 2023 and $49 million in 2024, and came close to breakeven (about -$8 million) in 2025. Owner earnings improved by about $42 million from 2024 to 2025. No year has been positive, so there is no earnings level to anchor on and no growth rate to extend. The question is whether contracted work can carry a breakeven-or-better business, not what a proven level is worth. 2026 so far. In the first half York lost $154 million on $209 million of revenue. About $96 million of that loss was stock compensation, mostly from IPO-related awards. We count it as a real cost to owners, but we do not treat it as recurring at that size. Removing working-capital swings, the business consumed about $19 million of cash before stock compensation and capital spending in the half. After ongoing stock compensation and capital spending, it burned roughly $25-30 million before interest. Gross margin recovered to 24% in the second quarter from 11% a year earlier, with only small unfavorable contract estimate changes, so the cost overruns of 2023-2024 have not recurred this year. In August management cut 2026 revenue guidance to $375-405 million. Roughly half of the cut removed expected new awards, because the Pentagon is moving to IDIQ contract vehicles that start more slowly. The other half was supply-chain delays pushing revenue into 2027. Backlog fell from $642 million in March to $592 million in June, with over 55% expected within twelve months, and ALL.SPACE's backlog is not yet included. York has won task orders on new IDIQ vehicles (including selection for the Space Force NITE-STAR IDIQ in July), but these are vehicles to compete for orders, not funded backlog. We gave them no credit. Debt and cash. At June 30, 2026 York held $534 million of cash against $147 million of term debt (SOFR plus 2.25-2.75%, due November 14, 2028), and its $150 million revolver was undrawn. The credit agreement carries a minimum trailing-revenue covenant of about $246 million, which current revenue clears comfortably. After the $155 million cash payment for ALL.SPACE in July, net cash is about $232 million, or $1.69 per share. The debt's floating cost is close to our yardstick, so we made no adjustment for it. York also owes former owners 85% of any tax savings it realizes from pre-IPO tax assets. Because York is loss-making, that obligation costs nothing in any case below. It would only bite on a sale of the company. Each case values the business from July 2026 onward, then adds the net cash. Base case: York keeps consuming cash while it delivers the existing backlog, absorbs three acquisitions whose losses are not separately disclosed, and carries public-company costs. Business cash flow before interest is about -$30 million in the second half of 2026 (management has said acquisition costs will weigh on the half). It is -$45 million in 2027 as delayed revenue lands but integration continues, -$30 million in 2028, -$15 million in 2029, and roughly breakeven thereafter. We credit no positive earnings. York has never produced them, and future SDA tranches, Golden Dome work and terminal sales are prospects rather than contracts. The burn is worth about -$112 million today. The business is worth about -$112 million, the company holds $232 million more cash than debt, and the difference is about $120 million, or $0.87 per share. Bear case: the named risks are York's own record on fixed-price satellite programs and the SDA's ability to cut or terminate work. York booked unplanned labor, material and overhead overruns in 2023, and gross margin fell to 13% in 2024, when the business lost about $49 million before interest. The SDA can terminate for convenience, and its budget depends on annual appropriations. In this case the Tranche 1 and 2 programs finish with no comparable follow-on in time, IDIQ orders stay small, and the overruns recur. Business cash flow runs about -$35 million in the rest of 2026, -$90 million in 2027, -$70 million in 2028 and -$45 million in 2029, then -$20 million in 2030 before a restructuring cuts the business back to breakeven. That is worth about -$236 million against $232 million of net cash, or about -$0.03 per share: the company would owe slightly more than it is worth. In this case most of the cash is gone by the November 2028 term-loan maturity. Refinancing or new equity would then come at shareholders' expense. Bull case: the backlog converts on schedule, supply-chain delays clear in 2027, and the margin and scale reached in 2025 and the second quarter of 2026 hold. Business cash flow is about -$20 million in both the second half of 2026 and 2027, then -$5 million in 2028. It turns positive at about $20 million a year from 2029 for a decade, roughly 5% of today's revenue with no growth assumed, then fades to zero over four years. Nothing contracted supports it beyond that. The business is worth about $101 million, plus $232 million of net cash, or about $2.42 per share. We did not credit ALL.SPACE terminal growth, Golden Dome, SDA Tranche 3 or IDIQ task orders beyond what is in backlog. None is contracted at a scale we can measure, and York has not yet shown it can win IDIQ orders at the size of its past tranche awards. What changed since our previous analysis. The business facts are the same: no new filing has been made since August. Our earlier figures subtracted a full year of 2026 losses from a cash balance that already reflected the first half of the year. Correcting that overlap lifts the base and bull cases modestly. The bear case is essentially unchanged. Accounting judgements. We removed contract-asset and contract-liability swings from operating cash flow. We counted all stock compensation, including the 2026 IPO awards, as a real cost. We treated amortization of acquired intangibles (about $11-12 million a quarter, from the 2022 buyout and later deals) as a sunk cost, but credited no persistence beyond what backlog supports. Goodwill of about $794 million on the balance sheet is given no value. Share counts before 2026 are the 95.1 million shares the former LLC units converted into. ALL.SPACE's own debt and losses were not disclosed in the filings we reviewed. We assumed its debt was settled within the purchase price. Margin of safety price. We are not confident of any earnings level, because there is none: three years of negative owner earnings, one dominant customer, and a 2026 that has stalled. The worst plausible outcome is an SDA budget shift or termination for convenience while the acquired businesses add losses. That would burn through the net cash before the 2028 loan maturity. The balance sheet survives two bad years, not four. If we are wrong about an SDA follow-on, the shares are worth roughly nothing. If we are wrong about the acquisitions' losses, the cash cushion shrinks faster. No dividend is paid during the holding period. What can be demonstrated today is the net cash, and it is shrinking by perhaps $50-80 million a year. No margin-of-safety price applies on price alone. Once York shows two consecutive quarters in which it funds its operations and capital spending without customer prepayments, the base-case burn is largely gone. Value then centers on roughly $1.40-1.70 of remaining net cash plus a business at or above breakeven. From $1.10 a 20% annual return is implied by the cash alone plus a move to the modest positive cash flow of the bull case within about three years. That is our margin of safety price, and it applies only after that condition is met.
