Chapter 4

What New KBR is worth on its own economics

After the planned spin (The MTS Spin-Off), continuing holders keep Sustainable Technology Solutions — "New KBR." It is a real process-technology licensor: 85-plus proprietary technologies across ammonia, chemicals, refining and circular processes [1]. But its FY2025 reported ~21.6% margin overstates the durable business. Strip one LNG construction joint venture — including a $134 million one-time favorable estimate change — and underlying margin runs in the mid-teens. The moat is genuine, and a minority of the mix.

The business that remains

STS is the segment that becomes the standalone company. It licenses a portfolio of "over 85 innovative, proprietary, sustainability-focused process technologies" spanning four verticals — ammonia/syngas, chemicals/petrochemicals, clean refining, and circular-economy processes — and wraps that IP in engineering, proprietary equipment, catalysts and advisory services [2]. Its record over five years is one of genuine expansion: revenue nearly doubled from $1.19 billion in FY2021 to $2.21 billion in FY2025, and segment operating income swung from a $30 million loss to $477 million [3].

The margin arc — negative in FY2021, 3.8% in FY2022, then a step to roughly 19–22% from FY2023 — is the number that carries New KBR's valuation. It also tracks, almost exactly, the swing in profit from joint ventures KBR does not control.

What the ~22% margin contains

KBR itself now separates the layers. On its Q1 FY2026 call, management broke STS into a margin tier: proprietary technology licensing, engineering solutions and complex program development earn above 25% adjusted EBITDA margins; proprietary equipment, catalyst and domestic maintenance (accessed "primarily through recurring JV") sit below 10% [5]. The high-margin licensing core is real. It is also not most of the revenue.

The clearest evidence is management's own ex-LNG cut. STS's Q1 FY2026 adjusted EBITDA margin was 21.9%; excluding a single LNG project it was 16.1% [6]. Management was blunter still on the call: "growth in our services business has outpaced technology sales, resulting in margins of approximately 15% with the LNG project adding an incremental 500 basis points" [7]. The premium label is "technology licensor"; the mix has drifted toward lower-margin services, and a construction JV supplies the difference between mid-teens and headline.

The full-year segment note tells the same story on an operating basis. Of STS's $477 million FY2025 operating income, $177 million was equity in earnings from unconsolidated JVs carried at no revenue in the segment's $2.21 billion top line; STS's own operations — gross profit of $429 million less $127 million of SG&A — earned roughly $302 million, a ~13.7% margin rather than the ~21.6% the segment total implies [8].

Sources: reported segment operating margin, FY2025 10-K [9]; ex-LNG adjusted EBITDA margin, Q1 FY2026 deck [10]; own-operations margin derived from FY2025 segment gross profit less SG&A [11]. Bases differ (operating vs adjusted EBITDA); shown to bracket the range.

The LNG project doing the lifting

The JV flattering STS is identifiable. KBR holds a 45% interest in KZJV, a joint venture with Zachry Group performing engineering and construction services for the Plaquemines LNG facility in Louisiana, accounted for by the equity method inside STS [12]. Equity in earnings from all unconsolidated affiliates rose $103 million, or 96%, to $210 million in FY2025, "primarily attributed to equity in earnings from services on an LNG project within our STS segment" [13].

What makes that lift fragile is its source. Buried in the critical-estimates disclosure: "During fiscal 2025, we recognized a favorable change in operating income of $134 million as a result of changes in estimates on an LNG project" [14]. On a cost-to-cost construction JV, a favorable change in estimate is a cumulative catch-up — profit pulled forward when the estimated cost-at-completion improves, not a repeatable run-rate. At $134 million it is larger than the entire $103 million year-over-year rise in equity earnings. Absent that revision, STS's JV contribution — and its reported profit growth — would have been roughly flat to lower.

That is what the multi-year equity-earnings line looks like: not an annuity, but a series governed by project timing.

Source: KBR consolidated results and equity-method roll-forward, FY2022–FY2025 [15]; FY2022 loss and FY2023 figure per prior 10-Ks.

Management's answer is that the backfill is "portfolio-based rather than a one-for-one replacement": as Plaquemines rolls off, higher-margin, more-recurring streams — technology licenses and JV operating-and-maintenance work — are meant to sustain "a 20%-plus weighted STS margin profile in 2026" [16]. That is a plausible plan, not a delivered fact, and it depends on the licensing tier growing faster than the services that have lately outgrown it.

The moat, measured against a real peer

The licensing IP is not marketing. KBR holds what it calls the leading ammonia technology "for all colors," the largest single-train ammonia design in the market, a first-of-kind ammonia-cracking process, plus drop-in SAF (PureSAF), plastics-recycling (Hydro-PRT) and brine-to-battery lithium (PureLi) technologies [17]. A century of process-licensing references is a genuine, hard-to-copy advantage in the narrow licensing slice.

The question for a standalone valuation is how much of the whole that slice is worth — and the cleanest benchmark is Technip Energies, the closest listed process-technology licensor in LNG, hydrogen and ammonia. Its strategy is explicitly to grow the "shorter-cycle Technology, Products and Services" business precisely because it "enhance[s] overall margins" [18]. Even so, that segment earned a 14.3% adjusted recurring EBITDA margin (12.9% at EBIT) in FY2025 [19]. A best-in-class technology-and-services energy business runs low-to-mid-teens margins — right where STS sits once the LNG catch-up is removed (16.1% ex-project) [20].

Sources: KBR STS adjusted EBITDA margins, reported and ex-Plaquemines, Q1 FY2026 [21]; Technip Energies TPS adjusted recurring EBITDA margin, FY2025 [22].

The read: STS holds a narrow, real moat in licensed process technology, but on blended economics it is a mid-teens-margin technology-and-services business, not a 22%-margin one. The gap to the headline is a construction JV, and part of that JV's FY2025 profit was a one-time estimate revision.

The tailwinds behind it

The demand backdrop is the strongest part of the bull case, and it is quantifiable. At its 2024 investor day KBR framed 2023–2027 market growth by vector: 100–125% for new energies (plastics recycling, sustainable aviation fuel, transport electrification), and 15–20% for both clean refining/petrochemicals and LNG/energy security [23].

Those are market-growth expectations, not booked orders, and the 100–125% figure sits on a small base. The near-term evidence is more mixed: FY2025 STS revenue grew only 2% [25], and the fourth-quarter release tied softer revenue to "delays in new awards as customers reassessed capital allocation, including reduced petrochemicals capex and a pause" in green projects [26]. What supports the growth case is the order book excluding the noisy LNG line: STS book-to-bill ex-LNG was 1.2x in Q1 FY2026 (1.2x trailing twelve months), backlog reached roughly $4.7 billion (up 9% year-over-year), and the ex-LNG pipeline exceeded $5 billion [27]. A 1.2x book-to-bill underpins mid-teens revenue growth — real, but a different pace than the investor-day vectors imply, and dependent on final-investment-decision timing KBR does not control.

What it means for the standalone value

New KBR is a growing, cash-generative technology-and-services business with a genuine but minority high-margin licensing core. The adjustment a value investor most needs to make is to the earnings base: the durable figure is closer to the ~$300 million of own-operations operating income (mid-teens margin) plus a normalized, recurring JV contribution than to the $477 million and ~21.6% the FY2025 segment total advertises [28]. Any multiple placed on the reported figure inherits a $134 million one-time estimate change and a construction JV that is rolling off [29].

The strongest fact against that caution is management's portfolio-backfill plan paired with a 1.2x ex-LNG book-to-bill: if higher-margin technology licenses and recurring JV work grow into the space Plaquemines vacates, the 20%-plus margin could prove more durable than a "one LNG project" framing suggests [30]. What would settle it is checkable and near: the Form 10 audited carve-out financials (expected public around September 2026) will show standalone STS margins with the JV disaggregated; the pace of the LNG roll-off against new JV and licensing bookings; and whether ex-LNG book-to-bill holds above 1.0x. Until those land, the honest base case values New KBR on mid-teens underlying economics, not the headline.
