Context: How Bolsa de Valores de Montevideo works, and what it makes issuers disclose · Uruguay on the LatAm Power Map
Inside every corrugated box that carries Uruguay’s beef, dairy, and fruit to market, there is a good chance Pamer made it. Papelera Mercedes S.A. — known universally as Pamer — is the only vertically integrated company in Uruguay’s corrugated-cardboard market, making both the paper and the finished box.

What it is
Pamer is the only Uruguayan company that uses a high proportion of its own paper in the manufacture of corrugated cardboard boxes — an unusual degree of vertical integration that keeps it independent of import disruptions in raw materials.
It leads the sector with roughly 50% of the domestic corrugated-cardboard market, producing packaging paper, liner, and finished corrugated boxes. Its main customers are Uruguay’s meat-packing, dairy, and fruit industries; it also holds the only Uruguayan licence to make Plaform trays — interlocking, humidity-resistant trays used for transporting fresh fruit.
It is also the largest exporter of corrugated cardboard in Uruguay. Quality is certified under ISO 9001:2015 for both box manufacturing and paper production.
Who owns it
Not published: The BVM filings page for Pamer (bvm.com.uy/operadores/documentos/76) lists the Acta de Asamblea and Memoria Anual PDFs, but those documents require authenticated download and their text could not be extracted. The BCU supervisory registry page (bcu.gub.uy — nroinst=7120) returned a server-authentication error during this research.
Uruguay’s securities law (Ley 18.627 and BCU circular 2.244) requires listed companies to disclose controlling shareholders in their annual reports, but the Memoria Anual PDF itself was not accessible in free text form through these sources at the time of writing.
Who runs it
Not published: The names of the president (chair), directors, and chief executive are disclosed in the Acta de Asamblea General Ordinaria de Accionistas filed annually on the BVM — most recently the Acta al 29.10.2025, filed 31/10/2025 — but that PDF was not extractable via open web access during this research. The company’s own website at pamer.com.uy carries no management page.
The money, in plain words
Not published: The audited accounts for the year to 31 December 2024 — *Estados Contables Anuales al 31.12.2024* — were filed with the BVM on 11 July 2025, and half-year accounts to 30 June 2025 were filed on 30 October 2025. Both documents are available as PDFs on the BVM portal but require authenticated broker/investor access; their text was not extractable in open web search.
Revenue, net profit, total assets, and equity figures therefore cannot be stated without risking invention. Under BCU rules applicable to BVM-listed issuers, quarterly and annual accounts must be filed within 60 days of period close, a requirement Pamer appears to be meeting.
The most recent directional signal from EMIS (a paywalled aggregator whose underlying source is the BVM filings) is that net sales fell roughly 2% and total assets contracted 0.2% in the most recent period, while the net profit margin declined — but these figures cannot be verified against the primary filing and are cited here only as a directional indicator, not confirmed financials.
What it is doing now
On 3 November 2025, Pamer filed a material-event notice (Hecho Relevante) confirming payment of a dividend to shareholders — continuing what has been a pattern of annual dividend payments going back at least to 2011, based on the BVM filing history. The October 2025 Ordinary General Meeting and the accompanying Memoria Anual and risk-rating report were all filed on 31 October 2025.
The company states it is investing in process development and new technologies to provide better packaging solutions, though no specific capital expenditure figures have been made public in accessible sources.
What to watch
- Pulp and recycled-fibre costs. Pamer is Uruguay’s largest consumer of recycled corrugated-fibre; global recycled-paper prices move its input costs directly.
- Export exposure. As Uruguay’s largest corrugated-cardboard exporter, it is sensitive to currency moves — particularly the UYU/USD and UYU/BRL rates — that affect price competitiveness across the Río de la Plata region.
- Market concentration. It is the only vertically integrated player in Uruguay’s domestic corrugated market, which is a durable competitive advantage but also a regulatory attention risk if market conditions become politically sensitive.
- Disclosure depth. The BVM’s authenticated-only PDF portal means that all headline financial figures remain practically inaccessible to ordinary investors without a broker account — a material transparency gap worth watching as Uruguayan market-development regulations evolve.
