The industrial cleaning company says its ERP nightmare is fading and robotics is accelerating, yet the stock sits 27% lower over 90 days—a disconnect worth examining.

The ERP overhang finally breaks
For five quarters, Tennant's calls were dominated by a botched ERP implementation that crippled order booking and hammered margins. The Q1 2026 call was a catharsis: “We were unable to book orders for 3 weeks in November...” — David Huml, President and CEO · 2026-02-24 By Q3 2026, the tone has shifted. CEO David Huml declared the "most significant disruptions are behind us" and quantified the fade:
When we think about the ERP related inefficiencies in Q3, they are much lower than they were in prior quarters... First half, it was around $10 million. In Q3, it was around 2 million and we expect Q4 to be 2 million or less.
That is a real inflection. The company also scrapped the planned EMEA deployment, a sensible retreat that reduces risk. The keyword ERP recovery has been a top theme since Q2 2026; now management is talking about value realization instead. The shift from fixing to optimizing is material—if it holds. The market has heard promises before; the stock is down 27% in 90 days, near its 52-week low, and still 46% below its 2024 peak. So the burden of proof remains.
The numbers confirm progress. Gross margin, normalized for a $6M tariff refund, was 40.4%, up 90bps from Q2 and ahead of guidance. “Excluding this benefit, gross margin was approximately 40.4% above the 39.5% we anticipated last quarter.” — Fay West, Senior Vice President and CFO · 2026-11-03 That is the first sequential margin expansion in a year. Operating cash flow improved to $11.9M from $5M in Q2, though YTD still negative. The gross margin has compressed 3 points over 11 years, so a single quarter does not reverse the trend, but it is a start.
Robotics: the growth engine that is no longer a science project
The real story is robotics. Revenue hit $37M, up 71%, and YTD $95.3M already exceeds all of 2025. “Robotics revenue in Q3 was $37 million, up 71% and ahead of plan...” — David W. Huml, President and CEO · 2026-11-03 Management reaffirmed $130-145M for 2026 and the $250M 2028 target. The portfolio is broadening: premium X Series with Brain Corp (exclusivity extended 3 years), and now a value-oriented performance series built with a contract manufacturer. The P1 vac—Tennant's first autonomous vacuum—targets soft-floor cleaning through distribution, a market the company previously ceded. This is a classic barbell strategy: defend the high end, disrupt the low end. If it works, TAM expands and the robotics business becomes less dependent on large strategic accounts.
The keyword history shows robotics is not new—it has been a theme for years. But the momentum has changed. In Q3 2025, Huml noted “Year-to-date, our sales are up 9% and our units are up 25%.” — David Huml, President and CEO · 2025-11-04 Now revenue is growing 71%, driven by new products and autonomy revenue. The question is whether this can scale profitably. Robotics still requires investment; R&D rose 28% yoy to $12.4M. But the gross margin drag is easing as volumes ramp.
The margin math and the market's disbelief
Despite the operational progress, the stock is in a deep drawdown. Why? Partly because guidance was only reaffirmed, not raised, and implies Q4 adjusted EBITDA margin of ~14%, below Q3's 15.1% (which included the tariff refund). Excluding the refund, Q3 EBITDA margin was 13.2%. So the underlying margin is still depressed. Inflation, freight, and parts availability persist. Management expects Q4 gross margin pressure from material inflation and elevated freight. The tariff refunds were a one-time benefit; ongoing tariff costs are still a headwind. Global tariff related uncertainty remains a live theme across industrials.
Balance sheet is another concern. Net leverage is 2x EBITDA, at the top of the target range. Effective net cash is negative $270M, a sharp reversal from positive $30M in 2015. Receivables are 88% of revenue, up 5 points yoy, reflecting the collections mess from ERP. Receivables to revenue at 88% is elevated. Management flagged collections as a top Q4 priority. If they can convert backlog and collect cash, leverage should improve; if not, the equity story gets harder.
What changed and why it matters
Three things changed this quarter. First, ERP is no longer the dominant narrative—management is explicitly trying to retire the topic. Second, robotics is now large enough to matter (11% of Q3 sales) and growing fast enough to offset core weakness. Third, the company is taking a more realistic stance on EMEA and APAC—orders in EMEA declined 9%, and management is reassessing China—without forcing an ERP deployment where risk outweighs reward. That is a more disciplined posture than we saw a year ago.
The tension is that the market is not rewarding these changes yet. The stock's 27% decline in 90 days suggests investors are focused on weak cash flow, leverage, and the margin recovery that still lies ahead. The backlog conversion in Q4 is the near-term catalyst: $118M backlog, with roughly half of the sequential sales increase expected from converting it. If that happens and margins stabilize, the narrative could shift from "ERP hangover" to "robotics inflection." If it does not, the skepticism will be justified.
For a small-cap industrial with a $1.2B market cap, the setup is asymmetric. The downside is cushioned by a 5% dividend increase and a portfolio that is genuinely differentiated in autonomous cleaning. The upside depends on execution. The company's own keywords tell the story: Robotics revenue is rising, residual impact is fading, and inflationary pressures remain. The market is betting the latter two outweigh the former. Tennant's job is to prove otherwise.
