Why aftermarket underwrites growth and economic value

Long‑term profitability in engineered products is shaped after the sale, where recurring services drive stability, margins and valuation.

In brief

• Lifecycle services generate outsized returns and buffer earnings through market cycles when product economics fluctuate.
• Companies that invest deliberately in lifecycle value secure deeper customer integration and more predictable cash flow.
• The biggest growth gains come from disciplined choices on where to compete and how to execute across data, pricing and delivery.

This article is part of a seven‑piece series exploring commercial, growth and innovation (CGI) and the strategies reshaping performance. 

For engineered products companies, aftermarket is not a secondary revenue stream. It is where most of the economic value is created.

Across industrial products, automotive, aerospace, defense and adjacent sectors, the aftermarket and services opportunity over an asset’s lifecycle is typically three to seven times the value of the original equipment sale. It is not only larger — it is structurally more resilient. Aftermarket demand is less exposed to capital cycles, program timing, macro volatility and geopolitics and it consistently carries a superior margin profile relative to original equipment.

Our experience across the product‑services continuum points to four priorities.

1. Characterize the lifecycle opportunity and set a realistic growth aspiration

A credible aftermarket strategy starts with a fact‑based view of the total lifecycle opportunity embedded in the installed base. This requires visibility into asset population, utilization by customer segment, operating conditions, duty cycles and component‑level reliability — and an understanding of how these variables translate into parts, service and upgrade demand over time.

While most organizations acknowledge these drivers, few systematically capture the data or apply rigorous analytics to quantify the opportunity. That gap is no longer defensible. Advances in data, digital and AI now make it possible — and essential — to build a granular, forward‑looking view of aftermarket potential. Companies that do this well establish a clear baseline of current share, identify white‑space opportunities and set performance‑anchored growth aspirations that align leadership, capital allocation and incentives.

2. Prioritize the growth vectors that matter

With the opportunity quantified, the next question is where to play — and how much each vector can realistically contribute. Traditional levers such as increasing share in spare parts, repairs, depot and field services remain foundational. But leaders go further.

Depending on asset criticality and industry context, growth may come from performance‑ and outcome‑based service models, modernization and upgrade programs, remanufacturing and circularity plays and “beyond‑the‑box” adjacencies. Financial orchestrations — such as captive finance, insurance, uptime guarantees or residual‑value management — can further expand the value pool. Increasingly, data‑ and AI‑enabled offerings create new sources of customer value by reducing downtime, improving planning and eliminating friction across the lifecycle.

The advantage comes from being explicit about where to play — and disciplined about where not to.

3. Close the gaps that inhibit share capture

Once aspirations and growth vectors are defined, execution becomes the binding constraint. Customers choose providers based on a small set of decisive factors: asset uptime, speed of response, technical capability, parts availability, ease of doing business, risk transfer and price.

Yet many organizations lack a rigorous, evidence-based understanding of how these factors drive choice across customer segments and use cases. The resulting share gaps almost always trace back to a familiar set of issues:

Aftermarket share isn’t lost — it’s conceded. Closing the gap is not a blanket transformation but a series of targeted moves — across portfolio, pricing, channels and operating model — applied in the right order. The advantage comes from identifying the constraint and breaking it deliberately.

4. Use data, AI and digital as force multipliers — not experiments

Data, digital and AI are no longer optional enablers of aftermarket performance; they are decisive sources of advantage. When deployed with intent, they improve demand forecasting, optimize parts positioning, raise service productivity and unlock new customer‑facing value propositions. When treated as pilots or innovation theater, they add complexity without moving the economics.

Effective aftermarket digital programs anchor investments to explicit economic outcomes: higher share of wallet, improved uptime, lower cost‑to‑serve and faster cash conversion. Digital capabilities must be embedded directly into core commercial, planning and service workflows — shifting aftermarket from a reactive set of transactions to a proactive, insight‑driven growth engine that scales judgment, not just automation.

A final thought for leaders

Aftermarket share is earned through a set of deliberate leadership choices: how clearly the lifecycle opportunity is understood, how explicitly growth vectors are prioritized, how decisively execution gaps are closed and how effectively data and digital are used to scale insight.

Organizations that treat aftermarket as a system — not a function — build resilience across cycles, embed deeply into customer operations and create an advantage that competitors cannot dislodge.

By bringing together commercial insight, operational execution and advanced analytics, organizations can turn aftermarket ambition into results. This combination can enable companies to build a clear view of the true opportunity, identify where share is being lost and define targeted interventions across availability, pricing and operating models.

Applying this integrated approach can help leaders prioritize and sequence actions, focusing investment on the few changes that drive the greatest impact rather than spreading effort across disconnected initiatives.

Such work is delivered through commercial, growth and innovation (CGI), a structured, customer-centered approach that aligns demand insights, operational capabilities and commercial execution into a coherent, actionable growth roadmap. The objective is straightforward: turn aftermarket share ambitions into executable plans grounded in data, operational reality and customer behavior.
