Aerospace alloys are doing the heavy lifting

01 Running thesis

A great core, one weak limb

Carpenter's story is now simple. Its main Specialty Alloys Operations business, or SAO, is running very well. In Q3 FY2026, SAO reached a record 35.6% adjusted operating margin, up from 33.1% in the prior quarter and 29.1% a year earlier.

The bull case rests on aerospace. Customers are ordering more material for aircraft and defense uses, and management says some customers want longer long term agreements. That matters because longer deals can mean better visibility and more pricing power when supply is tight.

The bear case has not gone away. Medical sales fell 23% in Q3 FY2026, and fell 29% excluding surcharge revenue. Management said bookings were up significantly, which may signal a turn, but the recovery has not yet shown up in reported sales.

Expectations are also higher now. Management said its fiscal 2027 earnings target is outdated and will give an updated view on the next earnings call. That is good for momentum, but it also raises the bar for the stock.

Apr 2026▲Q3 FY2026 strengthened the bull case. SAO reached a record 35.6% adjusted operating margin, and management said fiscal 2027 earnings guidance is outdated and will be raised.
Apr 2026→The same quarter kept the Medical concern alive. Medical sales fell 29% excluding surcharge revenue, though management said bookings were up significantly.
Jan 2026▲Q2 FY2026 showed stronger Aerospace and Defense demand and another record SAO margin at 33.1%. Management also raised the low end of full year operating income guidance.
Oct 2025▲Q1 FY2026 showed Aerospace and Defense bookings up 23% sequentially and SAO adjusted margin at 32.0%. New aerospace agreements included significant price increases.
Aug 2025▼The FY2025 filing confirmed the strong aerospace profit base but also showed Medical sales down 6% for the year. Higher fiscal 2026 capital spending added near term cash flow risk.
Jul 2025▲Fiscal 2025 was the most profitable year in company history, with $525.4 million in adjusted operating income. Management guided fiscal 2026 operating income to grow 26% to 33%.
02 Business model

Special metals for hard jobs

Carpenter makes premium alloys, including titanium alloys, powder metals, stainless steels, alloy steels, and tool steels. These materials go into places where failure is costly, such as aircraft engines, defense systems, implants, turbines, and other demanding equipment.

The company makes money by turning raw materials like nickel, cobalt, titanium, chromium, and iron scrap into billet, bar, rod, wire, strip, powders, and parts. It sells through plants, service centers, distributors, and direct customer relationships.

A key part of the model is pricing. Raw material surcharges help pass through metal cost changes, while long term agreements can lock in customer demand. In Q3 FY2026, the company said 43% of net sales for the first nine months were under firm price sales arrangements.

The model can break if aircraft demand slows, if medical destocking lasts longer, if raw material hedges and customer schedules do not line up, or if the company cannot run its specialized melt and finishing assets well.

03 Product portfolio

Where the alloys go

Growth engine

Aerospace and defense alloys

This is the biggest demand driver. Q3 FY2026 sales to Aerospace and Defense were $534.2 million, up 17% from the prior year.

Option

Medical titanium and specialty materials

Medical should be a strong end market over time, but it is weak right now. Q3 FY2026 Medical sales were $65.8 million, down 23% from the prior year.

Growth engine

Energy materials

Energy is getting help from power generation demand, including materials for industrial gas turbines. Q3 FY2026 Energy sales rose 49% from the prior year.

Steady

Industrial and consumer materials

This bucket includes markets such as semiconductor materials, fluid control, and consumer electronics. Q3 FY2026 Industrial and Consumer sales rose 7% from the prior year.

Option

Powders and additive products

Carpenter also produces metal powders and parts. This sits inside the smaller PEP segment, where improving Additive profitability helped offset some Medical weakness in Q3 FY2026.

Steady

Distribution and service centers

The company runs service and distribution centers in the United States, Canada, Mexico, Europe, and Asia. These help customers with stocking programs and smaller, faster orders.

04 Business segments

SAO carries the company

Specialty Alloys Operations88%growing fast
Performance Engineered Products12%declining

The mix uses Q3 FY2026 segment sales before intersegment eliminations: SAO at $735.1 million and PEP at $97.7 million. SAO is much larger and far more profitable, so the company is exposed to the aerospace cycle.

05 Risk factors

What could trip it up

Medical recovery does not arrive

Medium impact · Medium odds

Medical sales are still falling, even though management said bookings improved. If hospitals, device makers, or distributors keep cutting inventory, the PEP segment may stay weak longer than bulls expect.

We watchMedical sales growth turning positive, especially sales excluding surcharge revenue.

Aerospace cycle cools

High impact · Medium odds

Aerospace and Defense is now the main engine. A production delay at aircraft makers, weaker defense budgets, or lower customer orders could hurt volume, mix, and pricing.

We watchAerospace and Defense bookings, customer build rate comments, and any change in long term agreement demand.

Margins stop expanding

High impact · Medium odds

SAO has posted seventeen straight quarters of higher adjusted operating margins. That is excellent, but it also makes future comparisons harder. If mix worsens or productivity gains slow, investors may question peak earnings.

We watchSAO adjusted operating margin versus the Q3 FY2026 record of 35.6%.

Capital spending and expansion risk

Medium impact · Medium odds

Carpenter is investing in a brownfield expansion to add melt capacity. The company now expects fiscal 2026 capital expenditures of about $260.0 million. Cost overruns, delays, or weak demand when capacity arrives would reduce the payoff.

We watchCapital expenditures, project timing, and free cash flow after growth spending.

Leadership handoff

Medium impact · Low odds

A CEO transition is effective July 1, 2026. The risk is not that a new leader is bad by default. The risk is that execution slips during a period when pricing, capacity, and customer agreements all matter.

We watchAny change in fiscal 2027 guidance, capital allocation, or long term agreement strategy after the transition.
06 Quick answers

In one breath

What does Carpenter Technology actually make?

Carpenter makes premium specialty alloys and engineered metal products. These include titanium alloys, powder metals, stainless steels, alloy steels, and tool steels used in aerospace, defense, medical, energy, and industrial markets.

Why is Aerospace and Defense so important to CRS?

It is the largest end market and the main source of growth right now. In Q3 FY2026, Aerospace and Defense sales were $534.2 million, up 17% from the prior year.

What is the main risk for Carpenter stock?

The biggest company specific risk is that Medical remains weak while investors are paying for strong aerospace growth. The bigger market risk is a slowdown in aircraft and defense demand.

What should investors watch next?

The next major item is management's updated fiscal 2027 guidance. Investors should also watch SAO margins, Medical sales growth, and any detail on pricing and length of new long term agreements.
