News Summary
Two member-owned distributor groups announced a merger that will combine plumbing, heating, cooling and piping operations into a single national PHCP business unit representing 349 independently owned distributors and over $40 billion in combined sales. The deal, approved by both boards and memberships after extensive due diligence, will operate under a divisional structure covering Plumbing, HVAC, PVF, Decorative Brands and Waterworks. Leadership will be shared under a merger-of-equals framework with divisional boards restructured for equal representation. The transaction expands purchasing reach and logistics capacity and is set to become operational early next year.
AD and The Commonwealth Group Agree to Merge, Forming a $40B PHCP Network
A major consolidation in the plumbing, heating, cooling and piping supply channel is moving forward as two member-owned groups prepare to combine networks. The merger will bring together 349 independently owned PHCP distributors across the U.S. with total company sales of over $40 billion, creating a larger buying force and a restructured divisional organization for plumbing and HVAC product lines. The transaction will be completed in the coming weeks and will be operationally effective on January 1, 2026.
What the deal covers and leadership moves
The combined PHCP Business Unit will include AD Divisions for Plumbing, HVAC, PVF (pipe, valves & fittings), Decorative Brands, and Waterworks. Boards from both organizations voted unanimously in favor after months of confidential talks and due diligence. The merger is framed as a merger of equals. The incoming leader of the combined PHCP business unit was selected from the partner group and will report to AD’s chief executive.
Network and governance changes
Post-merger, the buying group is expected to change the size and structure of the AD network. The combination is reported to result in about 325 independently-owned PHCP distributors within AD’s network while AD’s divisional boards and vendor committees will be restructured to allow equal representation of the combined membership. The move follows other recent member-group combinations and is the latest among many consolidation steps that AD has completed over decades.
Where the parties are based
Corporate contact details for one party are listed at 500 E. Swedesford Rd, Wayne, PA 19087. The contact phone is 610.977.3100 and the general contact email is [email protected]. The partner buying group maintains offices in Dallas and Chicago.
Why this matters for PHCP distributors and suppliers
The deal combines supplier relationships and purchasing power across many branches and product verticals. The partners say the merger will reduce redundancies for supplier partners who previously worked with two groups, and will provide a larger, single buying channel for manufacturers and reps. Suppliers and independent distributors may benefit from aggregated purchasing, standardized committees, and centralized training and support resources that larger groups can provide.
How this fits with industry trends: construction tech and consolidation
The merger comes as consolidation and technology investment reshape construction and specialty-contractor markets. Technology tools such as software and drones that map large commercial builds have become as integral to the jobsite as traditional tools. Large technology companies have been buying specialized software firms, and billions in investment have flowed into construction tech. Rapid adoption of tools has gone hand in hand with mergers and acquisitions across software, distribution and contracting.
Persistent industry pressures — rising material costs, supply-chain disruptions, and a long-running skilled-labor shortage — are pushing contractors and distributors toward more efficient, digital ways of working. For many small and mid-sized contractors, consolidated platforms can shrink the number of separate apps needed for estimating, dispatch, time tracking, inventory, scheduling and billing. Aggregation also brings bigger players’ resources for training, customer support and regular updates, reducing long-term instability for users of small niche tools.
Practical benefits and real-world effects
Practical impacts include easier workflows for field crews and office teams. For example, a plumbing professional can use an integrated platform to generate estimates in the office, dispatch jobs to field techs, track time and materials, and send invoices all within one system. Prefabrication software and automated scheduling help smaller crews deliver larger jobs without overworking teams. Compliance and safety modules can standardize documentation across jobsites.
Risks and recommendations for contractors
Consolidation also brings tradeoffs. Contractors may end up paying for bundled features they do not need if pricing moves to enterprise tiers. Each acquisition can introduce new interfaces and require retraining. Fewer independent vendors can mean less competition and slower niche innovation. Contractors are advised to be proactive: audit current tech stacks, choose tools that integrate to reduce duplicate data entry, ask vendors about pricing transparency and exit clauses, clarify core vs. add-on features when negotiating, invest in training, and follow trade and M&A updates.
Broader market activity
Deal activity in construction and related industrial services accelerated through recent years, driven by private equity, strategic buyers, and large technology firms seeking end-to-end platforms. Buyers typically favor specialist contractors with stable service work, direct owner relationships, strong leadership and succession plans. Roll-up strategies, add-on acquisitions, and platform building remain common playbooks for buyers looking to scale.
Next steps and timing
The transaction will be completed in the coming weeks and will be operationally effective on January 1, 2026. Boards have approved the plan and the networks are preparing governance changes and divisional restructuring to accommodate the combined membership.
