Carpenter Technology Corporation (CRS) | The Buildout — AI Infrastructure
The Verdict
Carpenter Technology melts and finishes premium specialty alloys — the high-temperature metals that go into jet engines, industrial gas turbines, medical implants and semiconductor production tools. Its tie to the AI buildout is indirect and second-hand: turbine OEMs buy its alloys for hot-section components, and management links that demand directly to data-center power needs, while its materials also sit inside critical components in the semiconductor production process. The company does not describe itself as an AI company and does not break out revenue for either pocket. The honest frame is real exposure with an unquantified size, sitting inside a business whose earnings are still driven by aerospace and defense build rates.

What We Like
- SAO adjusted operating margin reached a record 37.8% in Q4 FY2026, up from 35.6% the prior quarter and 30.5% a year earlier — the 18th consecutive quarter of expansion.
- FY2026 adjusted operating income was $702M, up 34% over FY2025 and, in management's words, more than 5x fiscal year 2023.
- Management guided FY2027 operating income to $850M-$880M — roughly 21% to 25% growth — and framed it as a floor, while setting an FY2029 target of approximately $1.2B-$1.3B that it says is not peak earnings power.
- Management declined to give exact long-term-agreement percentage coverage, but a 'couple of very significant contracts' renew over the next two years — one large contract is currently in negotiation — and management says customers ask for 'more and more material. Not less.'
- The brownfield capacity expansion is on budget and on schedule for completion by the start of FY2028, is expected to be OI-accretive in FY2028 and to add roughly $150M of incremental operating income by 2030.
What We’re Watching
- Some aerospace structural customers are ordering below the levels 'they acknowledge they should be ordering at.' Management predicted the uptick 'in the next quarter or 2' from the 2026-07-30 call, and it had not arrived as of that call.
- The FY2027 guide's biggest input is the build rate Boeing and Airbus hit. Boeing has stated plans for 737 rate 47 per month and then 52, and management says aerospace growth depends on Boeing's success.
- Medical was down 30% year over year in Q4 FY2026 even after a 5% sequential rise, and PEP operating income of $7.1M was below $11.7M a year earlier. Q1 FY2027 PEP is guided to $6M-$7M.
- IGT material runs across a similar production flow path as aerospace materials, so it competes for the same capacity and can be crowded out by aerospace demand until the brownfield expansion comes online.
The thesis looks intact and strengthening on the numbers: margins, operating income, free cash flow and the multi-year framework all moved up in FY2026, and the guides the company set were met or exceeded rather than missed. What is not yet confirmed is the demand side. The FY2027 guide rests on Boeing and Airbus build rates and on structural customers moving off the sidelines, and management itself flagged that ordering gap. The open question is timing — management dated the inflection to 'the next quarter or 2' from July 2026 — with the added governance question of Tony Thene running the company indefinitely after Brian Malloy's death before his first call as CEO.
Earnings Beat
Carpenter reported Q4 FY2026 revenue of $851.0M at a 31.6% gross margin, with EBITDA of $245.3M. Operating income of $206.9M beat the previous record by 11% and rose 37% year over year, and diluted EPS was $3.23. The standout was the Specialty Alloys Operations segment: an adjusted operating margin of 37.8%, a segment record and the 18th consecutive quarter of expansion, on SAO operating income of $229.7M that came in above the guided $224M-$228M range. For the full fiscal year, adjusted operating income was $702M, up 34%, and adjusted free cash flow was $362.3M.

if you want to take that guide and say that's the floor for FY '27, you wouldn't get any pushback from me.— Tony Thene, Chief Executive Officer, 2026-07-30
Management tone: Management's tone hardened between the two calls. The Q3 FY2026 call called the prior FY2027 target 'outdated' and promised an update on the next call; the Q4 FY2026 call delivered it, framed the new FY2027 guide as a floor and said 'I wouldn't bet against this.' Management held the 2030 brownfield contribution at roughly $150M rather than raising it, and said FY2029 is not the peak of earnings power. The Q4 call opened with a tribute to Brian Malloy, who became CEO on July 1, 2026 and passed away before the call; Tony Thene said he would remain CEO for an indefinite period and that this is not an interim assignment.
Management Guidance
FY2027 operating income is guided to $850M-$880M, roughly 21% to 25% growth over FY2026, with Q1 FY2027 at $195M-$200M including SAO of $218M-$222M, PEP of $6M-$7M and corporate costs of approximately $29M. FY2027 adjusted free cash flow is guided to $400M-$430M and includes the remaining brownfield investment, with capital expenditure expected to be 'fairly ratable throughout the year.' Management ranked the FY2027 drivers as Boeing and Airbus build rates first, then price, then volume, then productivity, and projects 85%-90% free cash flow conversion excluding growth investments. The FY2029 target of approximately $1.2B-$1.3B reflects both the projected demand environment and the brownfield contribution.
Trajectory
Revenue moved from $733.7M in Q1 FY2026 to $728.0M, then $811.5M and $851.0M, with gross margin expanding from 29.5% to 31.6% across the four quarters and EBITDA margin from 25.8% to 28.8%. Mix is why reported growth trails volume: SAO ex-surcharge sales rose 11% year over year in Q4 on 23% higher volume, and management attributes the lower average revenue per pound to product mix rather than price cuts, noting aerospace-only pricing was up almost 10% year over year at Q3 FY2026. PEP is the exception — operating income fell to $7.1M in Q4 from $11.7M a year earlier — and trailing-twelve-month free cash flow covered 68% of net income.
The Model
The model projects FY+1 revenue of $3,517.5M and EBITDA of $1,053M, a 29.95% margin, then FY+2 revenue of $3,975.0M and EBITDA of $1,260M, a 31.7% margin. The near-term anchor is management's FY2027 operating income guidance and the long-term agreements due for renewal over the next two years. The FY+2 step depends on Boeing and Airbus building to their stated rates, the large LTA renewals repricing, and the brownfield expansion starting up in early FY2028.

What Could Go Right — and Wrong
- Boeing reaches 737 rate 47 per month and then 52, pulling aerospace structural orders up with it and filling existing SAO capacity.
- The structural ordering uptick management dated to 'the next quarter or 2' arrives, and the inflection is abrupt rather than gradual, as management expects.
- The large long-term agreement in negotiation and the renewals due over the next two years land at higher prices and higher shares of customer requirements, permanently enlarging the revenue base.
- The brownfield starts up on schedule in early FY2028, is OI-accretive in its first year and ramps toward $150M of incremental operating income by 2030 — a figure management says could prove higher.
- Semiconductor-driven industrial and consumer demand and data-center-driven industrial gas turbine demand both persist across multiple years, broadening revenue beyond aerospace.
- Aerospace structural customers stay on the sidelines through FY2027, and the FY2027 guide becomes a ceiling rather than a floor.
- Boeing stalls below rate 47 or slips its schedule, removing both the volume ramp and the pricing urgency behind the margin expansion.
- CRS's brownfield capacity comes online in early 2028 into demand that has not yet inflected, loosening the tightness that supports pricing.
- Mix keeps shifting toward lower-priced products, holding reported revenue growth well below volume growth and testing whether productivity and pricing keep covering the gap.
- Medical stays down year over year and PEP operating income stays below prior-year levels, leaving two of the broader demand vectors flat while the business remains concentrated in aerospace.
Looking Ahead
The next twelve months are about verification rather than new promises. Q1 FY2027 is the elevated preventive-maintenance quarter, so results against guidance of $218M-$222M of SAO operating income will show whether the 37.8% margin level holds through downtime. Management dated the structural ordering uptick to 'the next quarter or 2' from the July 2026 call, and Boeing has stated plans to move the 737 to rate 47 and then 52 per month against a combined Boeing-Airbus backlog of approximately 16,000 aircraft. A large long-term agreement is in negotiation and a couple more renew, all inside the next two years.
- Q1 FY2027Q1 FY2027 results — Tests whether SAO holds margin through a preventive-maintenance quarter.
- Next quarter or 2Structural ordering uptick — Management's dated call for aerospace structural order intake to inflect.
- Near termBoeing 737 rate rise — Plans for 47 per month then 52, against a ~16,000-aircraft combined backlog.
- Next 2 yearsLong-term agreement renewals — One large aerospace contract in negotiation; renewals reset price and share.
- Early FY2028Brownfield expansion start-up — Completion targeted for the start of FY2028; expected OI-accretive that year.
- FY2029FY2029 earnings target — Management says this is not peak earnings power, with brownfield still ramping.

The Company
Carpenter Technology produces and distributes premium specialty alloys — titanium alloys, powder metals, stainless steels, alloy steels and tool steels — for critical applications. The FY2025 10-K describes the company as 'a recognized leader in high-performance specialty alloy-based materials and process solutions for critical applications in aerospace, defense, medical, transportation, energy, industrial and consumer markets.' The revenue base is concentrated: aerospace was about 65% of revenue, and aerospace plus medical plus industrial gas turbines is 'well over 80%.'
The company runs two reportable segments. Specialty Alloys Operations (SAO) holds the premium alloy and stainless steel manufacturing, with integrated mills in Reading and Latrobe, Pennsylvania and Athens, Alabama, bar products in Orwigsburg, Pennsylvania and Elyria, Ohio, and a bar-and-wire mini-mill in Hartsville, South Carolina. Management says SAO is '95% plus of our segment operating income.' Performance Engineered Products (PEP) holds the Dynamet titanium business, the Carpenter Additive business and the Latrobe and Mexico distribution businesses, with titanium alloy production in Washington, Pennsylvania and Clearwater, Florida and a powder products facility in Athens, Alabama.
Business Segments
Competitive Landscape
The competitive dynamic in the source material is about qualification and capacity rather than price. Management says qualification cycles are long and the barriers to entry significant, and describes a 'unique collection of manufacturing assets, process technologies, metallurgical expertise and customer relationships' that it believes are 'extraordinarily difficult to replicate.' Set against that, the evidence set contains no sole-source disclosure for CRS at the filing level, while competitor ATI says it produces six of the seven most advanced nickel-based superalloys, including five where ATI says it is the sole source supplier.
- Documented competitor for 'legacy nickel-based alloys and superalloys and specialty steel alloys.' ATI reported Q2 adjusted EBITDA of $284M, up 37% year over year, a record $4.4B backlog, and lead times of about 12 months on nickel alloys and 20 months on premium titanium. ATI also appears in the wiring layer as a customer for vacuum-melted alloy bar stock.
- Haynes InternationalNamed in the supply-chain wiring layer as a competitor in high-temperature superalloys for industrial gas turbines and aerospace; not discussed by the company.
- PCCNamed in the supply-chain wiring layer for superalloys and specialty metals; not discussed by the company.
- VDM Metals GmbHNamed in the supply-chain wiring layer as a European specialty alloys competitor; not discussed by the company.
- AperamNamed in the supply-chain wiring layer for European stainless and nickel alloys, including its Imphy Alloys division; not discussed by the company.
Supply Chain
Carpenter sits upstream in the metals chain: it buys nickel, cobalt, titanium sponge and scrap, melts them in energy-intensive processes, and sells qualified alloys to aircraft, engine, turbine and medical manufacturers. The 10-K flags raw-material supply interruptions and tariff-driven price volatility; the filing extract contains no supply or sole-source records.
