Karman Space & Defense Reports Record Backlog and Raises Guidance as Customers Signal Demand Could Be 10x Prior Buy Rates
Q2 FY2026 earnings call, August 6, 2026
Karman Space & Defense delivered a second quarter that pushed its backlog to a record $1.3 billion, up 65% from the end of fiscal 2025, and prompted management to raise full-year guidance just months into new CEO Jon Rambeau's tenure. Revenue came in at $182 million, up 58% year-over-year and 20% sequentially, with adjusted EBITDA of $55 million, up 55%. The company now expects full-year revenue of $730 million to $745 million and adjusted EBITDA of $215 million to $222.5 million, implying 57% revenue growth and a 29.7% margin at the midpoint. Backlog now provides 95% visibility to the midpoint of that guidance, according to CFO Mike Willis.
Customers Are Now Asking for 10x, Not 2-4x
The single most striking data point from the call was Rambeau's disclosure that "some customers are now citing demand to increase certain annual production buys by as much as a factor of 10, which would dwarf earlier projections of 2, 3, or 4x multiples of current build rates." This is a meaningful escalation from prior commentary across the defense supply chain and suggests the replenishment cycle for munitions and interceptors is intensifying rather than plateauing. Rambeau tied this to recent contract activity across the industry, citing Lockheed Martin's more than $90 billion in THAAD and PAC-3 interceptor awards and the Navy's $76.6 billion award for five Columbia-class and nine Virginia-class submarines, both of which touch Karman's tactical missiles, hypersonics, and maritime defense end markets.
Second-Sourcing Trend Is a Net Opportunity, Not a Threat
With primes under pressure to diversify supply chains, analysts pressed management on whether the Pentagon's push for second sources on programs like PAC-3, where Northrop Grumman was recently added alongside Lockheed, could cannibalize Karman's sole-source positions. Rambeau's answer was unambiguous: "I would call it a net opportunity for Karman." He argued that Karman's early capacity investments position it to defend incumbency while also winning second-source slots where competitors have under-invested. Management cited five specific pursuits: separation motors for a major munitions program, a second-source role on a small propulsion system for a widely deployed anti-armor weapon, a solid rocket motor case opportunity, a shroud system for an interceptor program, and early engagement on a future lower-cost interceptor. KeyBanc's Michael Leshock asked whether second-source work carries different margins than legacy sole-source business; Rambeau said he does not expect "an appreciable either increase or decrease in margins," though the company may price more aggressively upfront to lock in long-term franchises.
Framework Agreements Progressing, With Space and Launch LTA Confirmed
Karman converted one of four previously disclosed contingent supply agreements into a firm contract during the quarter, a five-year space and launch long-term agreement that came in "just a bit below" the roughly $250 million value flagged last quarter. The other three contingent agreements remain in active negotiation, with Rambeau expressing "reasonable confidence" that initial contracts could land as early as the third quarter, with full conversion expected by year-end. He added that the eventual contract volumes are tracking "at or above" prior expectations. Management continues to model most of the revenue benefit from these frameworks as starting in early 2027 rather than this year, though Rambeau flagged potential upside if conversions happen sooner than planned.
Organic Growth Framework Reaffirmed, Not Slowing
Organic revenue grew 24.4% year-over-year in the quarter, within the company's stated 20% to 25% annual target range, and management reaffirmed guidance for 25% or higher organic growth in 2026, with acceleration expected in the third and fourth quarters. RBC's Ken Herbert pushed on whether the long-term 20% to 25% framework implied deceleration; Rambeau pushed back directly: "I did not intend to communicate a slowdown." At that growth rate, Rambeau noted revenue could double in three to four years even before accounting for acquisitions.
Walker Acquisition Opens a European Beachhead
Karman signed an agreement to acquire U.K.-based Walker Precision Engineering for total consideration of GBP 70 million, approximately $94 million, at an EBITDA multiple consistent with prior deals since the IPO. Management described the deal as establishing "a beachhead position in Europe with relationships across the spectrum of European defense primes," a notable strategic pivot for a company that has so far grown almost entirely through U.S.-focused, IP-rich bolt-ons. The deal is subject to regulatory approval and expected to close by year-end; pro forma leverage is expected to land near 3.5x adjusted EBITDA once it closes, versus 3.7x currently.
Capacity Build-Out: Salt Lake City Coming Online This Year
Karman is fitting up a 200,000-square-foot factory in Salt Lake City, with initial production capability expected before the end of 2026. First production equipment arrived last month. The facility will serve tactical missile, IDS, and hypersonics customers, and its ramp will free up capacity at the company's Seattle-area site for development and low- and full-rate production work. Separately, the company is shifting certain space and launch production from a longstanding business to its recently acquired Gulfport, Mississippi facility, leveraging its large-scale maritime manufacturing capabilities, a decision management uses to illustrate why it considers organic-versus-inorganic revenue splits a poor lens for evaluating the business. As Rambeau put it, moving output to whichever site is best suited to deliver it is "really organic business that we're simply moving to a recently acquired site," even though it gets counted as inorganic under standard reporting conventions. Management said it will now disclose organic growth only annually rather than every quarter going forward.
Free Cash Flow Becomes a 2027 Compensation Metric
With cash used in operations at negative $4 million in the quarter, driven by receivables and contract asset growth tied to the 58% revenue increase, management is signaling a shift in capital discipline. Free cash flow metrics will be incorporated into executive compensation starting in 2027, and the company expects $15 million to $20 million of free cash flow in the second half of 2026. Willis reiterated a longer-term target of converting 80% to 90% of net income into free cash flow once the current investment cycle in working capital and capacity matures. CapEx guidance remains at roughly 5% of revenue, or about $37 million, for the full year.
On the audit and controls front, Karman has transitioned to PwC as its new auditor and says it expects to fully remediate a previously disclosed material weakness by the end of 2026, with testing of controls continuing into early 2027, an overhang that will likely remain on investors' radar until formally closed out.
Management also disclosed a new AI initiative, internally called Project Moonshot, aimed at applying machine learning to decades of historical engineering and program data to speed up design, engineering, and proposal workflows, with the goal of improving contract capture rates over time. Details remain thin, with the company promising more specifics next quarter.
