Rotoplas Finally Turns the Corner on Services — Then Argues About How to Score It
Q3 2026: sales +10%, EBITDA +35% at a 13.2% margin, services EBITDA positive for the first time, leverage down a full turn — but ROIC still trails cost of capital, and the CEO says that's the wrong yardstick.

The quarter the "explore" side finally paid rent
For five straight quarters Rotoplas has been telling anyone who would listen that the margin story would arrive. This quarter it did. Net sales reached MXN 2.9 billion, up almost 10%; EBITDA rose 35% with the margin expanding 250 basis points to 13.2%; net income was "practically at break-even"; and net debt to EBITDA fell to 2.2x from 3.2x a year earlier. CEO Carlos Rojas Aboumrad did not hedge the framing: “Sales grew almost 10%, our fastest pace in several quarters. EBITDA grew 35%, with a margin of 13.2%, 250 basis points above last year.” — Carlos Rojas Aboumrad, Chief Executive Officer · 2026-10-22
The genuinely new item is buried in the segment detail, not the headline. Services — the money pit that has absorbed CapEx for years — posted positive segment EBITDA of MXN 4 million against a loss of MXN 63 million a year ago. That single line change is what the entire investment case has been waiting on, and the company's own keyword set confirms the shift: unit economics is now the single most prominent theme in the quarter, alongside a fresh emphasis on active subscribers — bebbia crossed 208,000, adding a record 14,000-plus net in the quarter.
Management's own framing for all of this is "ambidexterity" — run the core better while placing bets on the future. It is a good line, and unusually for a corporate coinage, the numbers this quarter actually support it. Core products grew almost 10% with a stable 15% margin; the water treatment business grew in Mexico and Brazil; and Mexico itself expanded EBITDA margin 150 basis points to 18% despite weak construction, low consumer confidence and heavy rain.
The question the CFO could not answer in the metric that was asked
Then BTG Pactual's Orlando Alcántara asked the only question that really matters for a capital-intensive small cap: ROIC has been stuck in the mid-to-high single digits for five years, below cost of capital, even after heavy investment. With invested capital now flat, what EBIT level clears the hurdle, and when?
The answer was candid but not an answer. “We are very focused on ROIC and on getting back to cost of capital... The ROIC on products is a much healthier ROIC, so it is more of a growth story that is complicated to see through ROIC.” — Andrés Pliego, Chief Financial Officer · 2026-10-22 The CEO went further, and this is the tension worth holding onto:
ROIC, I don't think is necessarily the right metric to look at services. For products, it will continue to be the main metric on how are we creating value, and it does very well for products.
That is a defensible argument — subscription and plant businesses are judged on unit economics and growth, not book ROIC — but it is also a metric being redefined at the exact moment it became inconvenient. Note the company's own keyword history: cost of capital ranks among the top themes this quarter precisely because the buy side pushed on it. The burden of proof now runs through the next two or three quarters of services EBITDA, not through the narrative.
Rain is doing the work, and management half-admits it
The most underrated disclosure was on the US, which grew about 31% in dollars and posted its sixth consecutive quarter of positive EBITDA — even as margin compressed to roughly 3% from 5% on supplier cost pass-through and entry pricing for new accounts. Alcántara asked whether that demand for storage was structural or project-specific, and the answer split the difference:
“Part of it is structural... Something else that did contribute is there was less precipitation, and just as an example, in the Colorado River Basin, there is much less water.” — Carlos Rojas Aboumrad, Chief Executive Officer · 2026-10-22
Flip that logic to Mexico and you get this quarter's headwind: “What happened recently in terms of water availability since 2024, and then 2025, and then 2026, is that we had much more rain, making the situation of water shortage change.” — Carlos Rojas Aboumrad, Chief Executive Officer · 2026-10-22 Weather cuts both ways, and it is now the recurring alibi in both directions. In the July call the CEO told the same audience that El Niño volatility was "the standard for us" and that he did not expect a repeat of the 2021-22 drought demand because “dams in Mexico are at high levels” — Carlos Roberto Rojas Aboumrad, CEO · 2026-07-23. Three months later, that abundant water is exactly why Mexican volumes are flat. The global tape noticed this theme earlier: low water levels spiked into the market top-20 in 2026Q2 alongside El Niño. Rotoplas is now on the wrong side of that same weather trade — which is precisely why the new-products story (vertical tanks, rainwater harvesting, roughly 8% of group sales in Mexico) has to carry the growth argument instead.
What quietly fell off the script
The most telling absence is the smart pump. It was the company's number one keyword last quarter; this quarter it does not appear at all. Similarly, "discipline pricing" — a top-three theme in Q2 — has been replaced by the softer "pricing strategy." Whether or not these are deliberate de-emphases, the pattern is consistent with a company narrowing its story to the two things that are working: services and expense control. Operating expenses grew under 3% against a 10% sales increase; that operating leverage, not pricing, is what delivered the EBITDA beat.
The balance sheet gave management room to do something else unusual: return cash while deleveraging. The board proposed a MXN 0.33 per share capital reimbursement (~MXN 160 million), taking total 2026 distributions to MXN 0.50 per share, on the back of MXN 1.1 billion of cash and operating cash flow up 17% year to date. That is a confidence signal, and it sits awkwardly beside the ROIC debate — paying out capital is easier than proving you can redeploy it above its cost.
The honest scorecard
Two things can be true. This was Rotoplas' best quarter in years on the metrics management controls — margin, leverage, cash, services inflection — and it was achieved in a market that, in the CEO's words, "did not help." Resin costs remained elevated (resin costs still a persistent theme), Argentina was only at breakeven on a shrinking volume base, and the US margin needs to be rebuilt next quarter by management's own admission.
That makes the setup genuinely interesting rather than routine: a small-cap industrial where the second derivative has turned, where a five-year investment cycle is showing its first real return, and where the bull case now depends on a business segment the CEO says shouldn't be judged by ROIC. Watch three things — whether services EBITDA stays positive without a growth-for-growth's-sake push, whether US margin recovers toward the prior ~5%, and whether resin-driven inventory unwinds as promised in Q4. If those three land, the cost-of-capital question answers itself. If they don't, the metric redefinition will look like what it currently resembles: a story told one quarter too early.
