Asset-as-a-Service: The Servitization Shift.
"Why sell a machine once when you can sell its performance forever? Servitization is the ultimate alignment of incentives."

The Fusion Equation
Performance × Responsibility = Value
Performance
Recurring Revenue
Responsibility
Product Life
"I’m very interested in Rolls-Royce being remunerated for the investments we make and the risks we take, and that needs to be fair." — Tufan Erginbilgic, CEO Rolls-Royce, Bloomberg, December 2023
The core tension
The servitized manufacturer sells an outcome and is paid only if the machine performs. Durability, efficiency, and reliability become the profit logic: embedded in the commercial model, not layered on top as compliance.
The manufacturer who earns per flight hour builds a different engine than the one who earns per engine sold.
The analytical depth
Heavy equipment manufacturers face cyclical demand and commoditization. Selling hardware is low-margin, high-volatility. Customers want uptime.
Rolls-Royce TotalCare: the airline pays per engine flight hour. Rolls-Royce earns more when engines fly, and has every incentive to keep them flying.
Kaeser Compressors does not sell compressors. It sells compressed air per cubic metre.
Service contracts generate +25% higher margins than equipment sales (McKinsey).
Near-zero churn on outcome-based contracts. The buyer stays while the seller performs.
The manufacturer who retains ownership has every incentive to build durable machines.
Servitization aligns the seller’s interest with the buyer’s and the product’s life.
Rolls-Royce / Kaeser Compressors
TotalCare · Power-by-the-Hour · Air-as-a-Service
50%+
Of Rolls-Royce’s civil aerospace revenue now comes from long-term service agreements, including TotalCare contracts where airlines pay per engine flight hour. Over 90% of Trent engines are on LTSAs. Civil Aerospace delivered a 20.5% operating margin in 2025 (vs 16.6% in 2024), driven by strong LTSA aftermarket performance and contractual margin improvements. Under CEO Tufan Erginbilgic, Rolls-Royce will only enter contracts that fairly compensate it for the investment and risk it bears over the full engine service life.
Rolls-Royce and Kaeser are not outliers. Caterpillar has built a multi-billion dollar Cat Financial and Cat Reman business around service contracts and remanufactured components. Atlas Copco, the Swedish industrial group, generates more than 40% of its compressor division revenues from services (Morningstar). The shift is now mainstream across heavy manufacturing: companies that moved earliest to outcome-based models have the highest margins, the strongest customer retention, and the lowest carbon intensity per unit of output delivered. The model works because the incentives are right.
“Rolls-Royce and Kaeser represent the two clearest proof points in heavy manufacturing. One sells thrust, the other sells compressed air: neither sells the machine. Both have built durable competitive moats by aligning their revenue model with the customer’s operational outcome. The sustainability benefit (longer-lived machines, fewer replacements, lower energy intensity) is a consequence of the commercial logic, not a goal added on top.”
The model works because the incentives are right.
Performance
Recurring Revenue
Service contracts generate +25% higher margins than equipment sales. Outcome-based models (charging per flight hour, per cubic metre of air, per tonne moved) convert the installed base into a predictable annuity. Near-zero churn: the customer stays as long as the seller performs. The shift from hardware revenue to service revenue is the most durable source of margin expansion available to heavy manufacturers today.
Responsibility
Product Life
The manufacturer who retains ownership of the asset has every incentive to design it to last, to build it for repairability, and to minimise its energy consumption in operation, because every failure is their cost, not the customer’s. Servitization turns Ecodesign from a regulatory constraint into a commercial imperative. The most durable machine is also the most profitable service contract. Responsibility and performance are the same calculation.

This case resonates?
Stop pricing the asset. Start pricing the outcome. The incentive structure determines the product design and the margin.
