Context: How Bolsa Mexicana de Valores works, and what it makes issuers disclose · Mexico on the LatAm Power Map
Mexico collects nearly 120,000 tonnes of waste every day, and someone has to move it. Promotora Ambiental — PASA — has been doing that job since 1991, and it is the only environmental-services company listed on the Mexican stock exchange.

What it is
PASA provides environmental services across Mexico and internationally, collecting private and domestic waste, building and running sanitary landfills, recovering recyclable materials, and generating electricity from the biogas that buried waste naturally produces.
Beyond basic collection, the business also covers water and wastewater treatment, and manages hazardous waste from oil-well drilling — a line that broadens its revenue beyond the standard municipal garbage contract.
PASA has traded on the BMV since November 2005 and is today the only environmental-services company listed on that exchange — a monopoly of a different kind, giving it a rare visibility premium among Mexican sustainability investors.
Who owns it
The largest single block of shares sits with Genpasa Environmental Holdings, S.á.R.L., which holds roughly 22% of the company. Alberto Eugenio Garza Santos — who also chairs the board — holds a further 9.1%, making him the third-largest shareholder.
Together, insiders control about 57% of the shares (EODHD data), leaving a free float of roughly 28% for outside investors; the top five shareholders alone account for 57% of the votes, so this is a company where a small group sets the direction.
Who runs it
Manuel González Rodríguez is the CEO (director general) of Promotora Ambiental, a role he held through the company’s 20th anniversary on the BMV in late 2025.
Alberto Eugenio Garza Santos serves as board chairman (presidente del consejo), with González Rodríguez leading day-to-day operations. A CFO name is not disclosed in available public sources.
The money, in plain words
Sales have grown every year: MXN 6.65 (US$0.38)B ($383M) in 2023, MXN 7.07 (US$0.41)B ($407M) in 2024, and MXN 7.71 (US$0.44)B ($444M) in 2025 — a compound annual revenue growth rate of roughly 7.6% (our calculation). Net profit grew faster, rising 19.4% in the most recent year, from MXN 252 (US$15)M to MXN 301 (US$17)M ($17.3M) (our calculation).
For every peso of sales, PASA keeps about 4.8 cents as net profit — a net margin of 4.84%, modest but consistent with a capital-heavy, contract-driven service business. For every peso owners have put in, it earns about 12 back each year — a return on equity of 12.4%, respectable for the sector.
At a price-to-earnings ratio of 14.2×, the market is paying MXN 14.23 (US$0.82)for each peso of annual earnings — not cheap for a slow-grower, but the near-monopoly listing status and long municipal concession contracts justify some premium. PASA currently pays no dividend.
The balance sheet carries MXN 1.34 (US$0.08)B ($77.2M) in cash (our calculation from reported figures); total debt is not separately disclosed in the structured data, but the company flagged a syndicated refinancing in June 2025, suggesting existing debt is being actively managed.
What it is doing now
PASA’s investor-relations page records a syndicated refinancing in June 2025, a board-level leadership change in April 2025, and the sale of its chemical-products subsidiary Lint in April 2025 — all pointing to a year of deliberate balance-sheet and portfolio tidying.
Through its industrial-services brand GEN, PASA is positioning itself in Mexico’s manufacturing zones to serve the wave of foreign factories relocating closer to the US border — a tailwind the company calls nearshoring, and one that could lift the higher-margin industrial-waste line faster than the municipal segment.
What to watch
- Concession renewals. Municipal contracts are periodically re-tendered; PASA lost a bid attempt for a long extension in Torreón, where its collection concession came up for renegotiation in 2025–2026. Contract concentration is the key risk.
- Margin expansion. Operating income jumped from MXN 521 (US$30)M to MXN 813 (US$47)M over two years (our calculation) — whether that pace continues, or whether rising fuel and labour costs compress it, is the margin story to track.
- Nearshoring revenue. If foreign manufacturers keep reshoring production to northern Mexico, GEN’s industrial-waste contracts could grow materially faster than the municipal base.
- Capital return. With no dividend and a growing cash pile, investors will eventually ask whether surplus cash is returned or deployed into acquisitions — particularly after the Lint disposal freed up management attention.
