APi Group is a global provider of fire and life-safety services: inspecting, servicing, monitoring and installing fire suppression, security, and life-safety systems, along with elevator and escalator service added through a 2024 acquisition, organized alongside a smaller Specialty Services business doing infrastructure, utility and specialty contracting work across the U.S. and Canada. Roughly 69% of 2025 revenue came from Safety Services and 31% from Specialty Services. In January 2022 the company acquired the Chubb fire and security business, which increased its revenue by roughly two-thirds and shifted the majority of revenue outside the United States, into the United Kingdom, continental Europe, Canada, Australia and Asia-Pacific. Much of the appeal of this business is that a large share of its work is inspection, testing, service and monitoring of systems that building owners are legally or contractually required to maintain — work that recurs on short cycles (contract terms mostly under six months) with high renewal rates, giving the business unusually stable, repeat revenue for an industrial services company. Management has also made pricing discipline and growing this recurring inspection/service revenue explicit priorities, and segment margins have been moving up as a result (the Safety Services segment's margin rose from 15.9% to 16.8% in the most recent year). We built owner earnings from reported cash flow from operations each year, then removed the swings caused by working-capital timing, backed out stock-based compensation (a real cost that isn't a cash outlay), and separated ongoing "maintenance" capital spending from the smaller slice of capital spending tied to organic growth. Non-cash charges such as the amortization of intangible assets acquired in the Chubb deal (roughly $220-240 million a year) are added back, consistent with treating them as sunk acquisition cost rather than an ongoing cash cost; the resulting figure is real, current cash-generating power, not an accounting construct. On that basis, per-share owner earnings were $1.29 in 2023, $1.36 in 2024 and $1.71 in 2025 (all figures restated for the 3-for-2 stock split the company completed in June 2025). We use $1.36 — the middle of those three years — as the starting point for our valuation, rather than jumping straight to 2025's stronger number, since one strong year isn't yet enough evidence that it's the new normal; it does, however, inform how we think about near-term growth. Base case: We assume continued growth in inspection and service revenue, pricing, and the kind of small, regularly-recurring bolt-on acquisitions the company has made for years, producing high-single-digit per-share growth in the near term, slowing gradually to a low-single-digit rate by year 10 as the business matures. Beyond that, we don't assume the acquisition machine keeps compounding value forever; we credit only what a large base of legally-mandated, recurring inspection work can be expected to sustain on its own — roughly 2% growth indefinitely. That produces a value of about $46 per share. Note that growth in 2025 (26% per share) ran well ahead of this assumption, helped by a large 2024 acquisition; we've deliberately not assumed a repeat of that pace without more evidence it's sustainable. Bear case: The Specialty Services business is tied to U.S. infrastructure and construction activity, which the company itself flags as cyclical, and roughly $2.8 billion of debt (which grew further in the first half of 2026) means a downturn would be felt more acutely through interest costs. In this case, we assume Specialty Services softens and integration/insurance costs weigh on margins, producing a mid-single-digit percentage decline in per-share owner earnings over the first few years before stabilizing at a low, flat rate reflecting the still-mandated inspection base. That produces a value of about $20 per share — still a real, positive value because most of the business is protected by the recurring, mandated nature of its core work, but a business worth meaningfully less than today's growth story implies. Bull case: If the company's own demonstrated levers — inspection/service growth, pricing, and continued disciplined bolt-on acquisitions — keep performing at close to their recent pace for several more years before naturally slowing, the value comes to about $72 per share. The margin-of-safety price is around $19 per share. That price sits close to our bear-case estimate, and from that price the base case implies roughly a 20%-a-year return if the shares later trade near our base-case estimate of fair value. One thing worth stressing to a skeptical reader: this is a company built substantially through acquisitions, including one in January 2022 that increased its revenue by roughly two-thirds almost overnight. We tested whether the recent acceleration in growth was simply a sugar high from the 2024 acquisition wearing off; the company's first-half 2026 results instead show revenue growing at a similar-to-faster pace than 2025's full year, which argues against that concern, though it is only six months of data.
