The Acquisition Playbook.

Three patterns run through SMITH A O's acquisitions — what it looks for, how it pays, and how it folds in what it buys.

01
Acquisition criteria
Buy the platform, then bolt on.
A. O. Smith enters a category with one anchor deal, then compounds it with tuck-ins. Water treatment began with the $87M Aquasana purchase in 2016 ('we entered the water treatment market'), followed by Hague (2017), Water-Right (2019, $107M), Master Water (2021), Atlantic Filter (2022), Water Tec (2023), Impact (2024) and Pureit (2024). Boilers began with the $418M Lochinvar deal in 2011.

02
Capital deployment
Stay in the water lane.
Every acquisition since the 2011 divestiture of its electric-motor business has been in water: heaters (GSW, Giant Factories), boilers (Lochinvar), treatment and purification (Aquasana through Pureit), and now water-management controls (Leonard Valve). Management repeatedly frames deals against its stated goal 'to become a leading global water technology company.'

03
Integration approach
Fund big platform deals with debt, tuck-ins with cash.
The largest deals — Lochinvar ($418M, revolver), Giant ($199M, cash plus borrowings) and Leonard Valve ($470M, a new $470M term loan) — used credit facilities, while sub-$150M treatment tuck-ins were funded from cash on a debt/cash-free basis.
