Tennant Co (TNC)

Tennant manufactures and sells floor-cleaning equipment and supplies to hospitals, schools, offices, warehouses, and airports. It is one of the most visible makers of walk-behind and ride-on floor scrubbers and sweepers in the world — machines you see in hallways and parking garages every day. The business is split between selling the machines (lumpy, one-time revenue) and supplying the consumables they need (sticky, recurring income).

The line captures what makes Tennant different from a typical equipment manufacturer. A hospital needs its floors clean every single day. Once it has bought a scrubber, it must buy detergent, pads, squeegees, and eventually replacement parts to keep it running. That recurring stream — consumables and service — is what buys the stock, not the sporadic sale of a machine.

From floor wax to digital cleaning

Tennant’s history runs back over a century to the days of floor wax and elbow grease. The company began by selling industrial floor wax in the 1840s, then evolved into selling machines to apply that wax, then into making the machines themselves. By the mid-20th century, Tennant was a recognized name in industrial cleaning equipment — the green machines in hospitals and office buildings.

For decades the business model was straightforward: sell cleaning machines with modest margins, then slowly bleed that customer base as machines aged and wore out. Tennant eventually realized the real money was in locking customers into an ecosystem of supplies and service contracts. If a hospital owns a Tennant scrubber and must buy Tennant pads and Tennant detergent every month, Tennant has recurring revenue that does not require a new machine sale. That shift — from equipment-centric to equipment-plus-ecosystem — has been the dominant theme in the company’s strategy over the past two decades.

The latest chapter is digitization. Modern Tennant machines can be connected to the internet, reporting usage, maintenance needs, and performance data back to fleet-management software. A facility manager can monitor whether the night-shift crew is actually cleaning all the required areas, how often pads are being replaced, and when equipment is due for service. This software layer turns cleaning into a managed service, creates switching costs (customers get locked into Tennant’s system), and generates predictable revenue from subscriptions and data.

The two revenue streams

Equipment sales are the smaller, lumpier part of the revenue picture. A single purchase of a floor scrubber might run $10,000–$30,000 depending on the type, and it happens infrequently — perhaps once every 5–7 years for a typical customer as the old machine reaches the end of its useful life. Tennant sells thousands of machines annually, but the revenue is concentrated and hard to forecast month to month.

The consumables and services business is steadier. A hospital or retail chain that buys detergent, pads, and brushes from Tennant might spend $5,000–$15,000 per year (depending on the size of the facility and the cleaning standard), but it spends that every year, year after year, with little promotional effort required. This revenue is recession-resistant — people and facilities still need to be clean in downturns — and it has higher margins than equipment because the marginal cost of one more pad or bottle of cleaner is modest.

Over the past decade, consumables and services have grown from roughly 40% of revenue to closer to 50%, which is strategically important: the company is shifting from a “sell machines and hope they break” model toward a “lock in recurring revenue” model.

The competitive moat: switching costs and customer relationships

Tennant competes against larger diversified facilities-management suppliers like Ecolab and against regional equipment makers in various markets. What keeps Tennant from being trampled is switching costs. A hospital that has decided Tennant is the brand it wants, that has trained its staff on the machines, that has built cleaning protocols around Tennant’s products, and that is locked into a supply contract with Tennant will not lightly switch to a competitor. Changing equipment affects everything downstream — training, inventory, supplier relationships — so inertia is powerful.

This is why Tennant invests in digital systems and software: each customer that signs up for a software platform, trains its people on the analytics dashboard, and builds workflows around the system, becomes much stickier. The equipment itself might be roughly equivalent across manufacturers, but once you have committed to Tennant’s digital ecosystem, leaving is expensive.

Geographic spread and customer concentration

Tennant operates globally, with manufacturing and distribution in multiple regions. The developed markets — the United States, Europe, Japan — are mature and competitive, but they are also where facilities-management standards are highest, so customers invest in quality cleaning. Emerging markets represent growth opportunity but are also lower-margin because customers are more price-sensitive.

Tennant is not heavily dependent on any single customer — no major customer accounts for more than a small percentage of revenue — which reduces risk from losing a big account. The customer base is diverse across industries: hospitals, schools, offices, airports, manufacturing facilities, retail stores. This diversity helps buffer downturns in any one sector.

Operational challenges and the cyclical nature

The industrial-equipment business is cyclical. In a recession, a school district defers buying new cleaning machines, a hotel postpones renovation and equipment refresh, an office park delays maintenance investments. Consumables are more resilient — people still clean — but they can soften too. Tennant is thus exposed to the economic cycle, with revenue growth strong in expansions and flat or negative in downturns.

Tennant also faces supply-chain complexity: it sources parts globally, manufactures in multiple locations, and ships equipment and supplies worldwide. Disruptions — shipping delays, semiconductor shortages, port closures — can affect production and delivery timelines. The company has worked to diversify supply and nearshore some production, but the exposure remains.

The path to recurring revenue

Where Tennant is pressing hardest is the shift toward managed services and software. Instead of simply selling equipment and consumables, the company wants to become a service provider: selling facility managers analytics, predictive maintenance, optimized cleaning schedules, and inventory management. This is higher-margin than just selling machines, and it is more defensible because it increases switching costs and creates a stickier customer relationship.

This shift is not simple — it requires building software capabilities Tennant did not historically have, hiring talent from outside the equipment industry, and reorganizing go-to-market to focus on relationships rather than transactions. Some of Tennant’s recent acquisitions have been venture-backed software companies aimed at acquiring this expertise. The success of this transition will largely determine whether Tennant remains a strong independent company or becomes a mature cash cow.

Watching Tennant’s progress

Track the shift in revenue mix: how much is equipment versus consumables and services, and which segment is growing faster. Watch margins, especially gross margin in the consumables business — if that is expanding, the company is making progress. Monitor customer-retention rates and the adoption of Tennant’s digital platforms. Finally, observe capital expenditure and acquisition activity: is the company investing aggressively in software and capabilities, or managing for short-term cash? A company serious about the digital transition will show that in its balance sheet.
