Otis Worldwide Corporation

Otis is a genuinely exceptional business trading at a fair price — which is satisfying to analyze and frustrating to act on. The service annuity generates extraordinary returns on capital with almost no reinvestment, the switching costs are regulatory and psychological as much as contractual, and the IoT overlay is creating a data moat that independent servicers cannot replicate without the OEM's unit-specific fault history. The problem is that the market understands most of this, and current multiples reflect a business that earns well and grows modestly — which is accurate. The trajectory is improving in quality even as it decelerates in quantity. Service is claiming a larger share of the revenue base each year, which structurally reduces cyclicality and improves cash conversion. Modernization orders surging suggests the aging global installed base is finally becoming a tailwind — buildings built in the 1980s need elevator replacements, and Otis captures that cycle both on the equipment sale and the subsequent service contract. The business five years from now looks more like a pure-play service compounder and less like a manufacturing business exposed to construction cycles. The single biggest risk is not China's property market — that pain is largely known and partially priced — it's the long-term regulatory threat to OEM diagnostic lock-in. European building systems regulators have already begun scrutinizing software-enabled switching barriers in adjacent categories. If that pressure reaches elevator maintenance and forces open diagnostic interfaces, the proprietary data moat Otis has been building through Otis ONE gets commoditized, independent servicers become credible substitutes, and the service margin story that underpins the entire investment thesis starts unwinding. That outcome is not probable, but it is the scenario that genuinely breaks the thesis.
