How Selling Systems Changes the Economics of a Business

Today, I’m digging into Acuity Brands (AYI).

They sell lighting and building systems, and they’ve built a big business by owning the relationships with a large network of installers. They are another case study in how winning with those that distribute/install products in your market is a powerful go-to-market strategy.

A few more things that stood out to me:

• Most of their revenue flows through a large independent sales network. If you control who gets specified, you don’t have to fight as hard on price.

• They’ve pushed beyond basic lighting into controls and building systems, which tend to stick around longer once installed. By building a system vs. components, you remove the commodity nature of the components themselves.

• Margins have improved over the last few years, which is not easy in a physical product business.

Not everything is clean:

• Growth recently leaned heavily on a large acquisition, and that deal flipped the balance sheet from net cash to net debt.

• Lighting itself is still a competitive, price-sensitive category.

The main takeaways for builders are this: Acuity wins by controlling the channel and bundling systems instead of selling parts.

With that, I'll see you tomorrow.

TL;DR

• Acuity (AYI) builds lighting and smart-building systems

• They "win" by controlling specification, distribution, and installation relationships.

• The core insight: in mature physical categories, channel power and installed-base stickiness matter as much, or more, than product specs.

• Growth in recent years was driven by a shift toward controls, software, and intelligent spaces, especially after the QSC acquisition.

• They've experienced consistent margin expansion, but balance-sheet risk has increased materially with debt-funded acquisitions.

• Entrepreneur takeaway: "boring" industries reward operators who own the channel and bundle systems.

The N.O.O.B. Nine — Competitive Powers

The Nerd Out on Business Nine is made up of Hamliton Helmer's famous "7 Powers" of competitive advantage (Scale Economies, Network Economies, Counter-Positioning, Switching Costs, Branding, Cornered Resource, and Process Power) combined with two of my own (Data Flywheel and Distribution Advantage).

Average Score: 3.1/5 - A solid moat built on distribution and process strength, but it is not unassailable.

Memorable Marketing

• Acuity markets primarily to specifiers, contractors, and integrators, focusing on risk reduction and credibility.

• Standout tactics include:

  • Atrius platform launches that reframed lighting as infrastructure.

  • Trade-show demos using VR to shorten the sales cycle.

  • Heavy use of third-party validation such as design awards.

• Tactical takeaways:

  • Market to the buyer’s fear of making a wrong decision.

  • Use demos and simulations to make invisible products tangible.

  • Turn your channel partners into your primary marketing engine.

AI Uses & Opportunities

• Current use:

  • Early AI integration in controls, analytics, and internal processes.

• Future opportunities:

  • Auto-commissioning and configuration of building systems.

  • Predictive maintenance to reduce service costs.

  • AI-driven energy optimization services.

  • Spec-to-install copilots for contractors and integrators.

  • Self-healing AV and meeting-room systems via Q-SYS.

Bumps in the Road

• Integration risk from large acquisitions, especially QSC.

• Higher tariffs and input costs pressured gross profit.

• Recurring special charges signal organizational complexity.

• Expanded cyber and AI-related risk exposure.

• Competition from both traditional manufacturers and software-first entrants.

Your Swipe File

• Own the channel before you try to own the category.

• Bundle systems to escape commodity pricing.

• Acquisitions can accelerate strategy but increase balance-sheet risk.
