Sociedad Agrícola e Industrial San Carlos S.A.

What it is

Incorporated in Guayaquil in 1897, the company grows, harvests, and processes sugarcane to produce refined white sugar, brown sugar, and related products. It farms 25,000 hectares of cane across the cantons of Marcelino Maridueña, Naranjito, and El Triunfo in Guayas province.

San Carlos sells about 33% of all sugar consumed in Ecuador, making it the country’s market leader in the category. Beyond sugar, it is an integrated producer of cogenerated power and alcohol — burning the fibrous residue of the cane to generate electricity, and fermenting the molasses into industrial ethanol.

Who owns it

The company has been listed on the stock exchange for 25 years; share capital stands at $133 million spread across approximately 981 shareholders, with no single dominant bloc — a structure the directors say gives them a clear accountability mandate.

The González Portés family anchors the board and the broader corporate group. The related holding vehicle, Inversancarlos S.A., is itself made up of roughly 900 shareholders and its board is chaired by Ing.

Mariano González Portés. Inversancarlos was founded with Sociedad Agrícola e Industrial San Carlos as one of its original shareholders — tying the family’s industrial empire back to the mill.

Not published: the precise ownership percentage held by the González Portés family in Sociedad Agrícola e Industrial San Carlos S.A. itself is not disclosed in public filings available on the Bolsa de Valores de Guayaquil issuer page or the Superintendencia de Compañías portal (SCVS), the latter of which requires a JavaScript-enabled session to access individual shareholder schedules (Nómina de Accionistas).

Who runs it

Mariano González has served as president of the board since 1980; Xavier E. Marcos has held the position of general manager since 1971 — a tenure of more than five decades that is unusual even by Latin American family-business standards.

Mariano González Portés currently serves as Presidente of Ingenio San Carlos.

Ángel Zurita Albán has been identified in company publications as the Gerente Financiero (chief financial officer). The company’s investor-relations pages do not publish an updated management directory, so current executive roles beyond these names could not be confirmed from available sources.

The money, in plain words

No structured financial data was available from EODHD for this company. Third-party commercial databases estimate annual revenue at roughly $158 million (Dun & Bradstreet) to $147 million (ZoomInfo) — but neither source specifies the reporting year or cites a primary filing, so these figures should be treated as indicative rather than audited.

Not published: audited revenue, net profit, net margin, return on equity, price-to-earnings ratio, and dividend yield for the most recent fiscal year are not accessible from sources opened during this research. The SCVS (Superintendencia de Compañías, Valores y Seguros) requires all active companies to file annual financial statements by 30 April each year (Resolución No. SCVS-INC-DNCDN-2016-011); the BVG issuer page for SCD (emicodi=C.82) shows trading data but not the underlying financials without navigating to gated filing sections.

What is visible: the share price stood at $0.55 as of late June 2026, giving a market value of roughly $73 million against a stated share capital of $133 million (our calculation) — meaning the market currently values the company at a discount to its book share capital, which is unusual and may reflect low trading liquidity rather than a fundamental judgment on the business. The stock has been listed for 25 years but trades infrequently on a small exchange, so the price is a thin signal.

What it is doing now

Ecuador’s sugar industry had a difficult 2023 — irregular rains shortened the harvest season from six to four months — but 2024 brought a full recovery, with the industry recording its best production year since 2020. National output reached roughly 520,000 metric tonnes of sugar, enough to cover domestic demand well into 2025.

San Carlos has been pushing into export markets — the United States, Peru, and others — and recently received Kosher and Halal certifications, opening the door to Jewish and Muslim consumer markets globally. The group also runs Soderal, a distillery created in 1993 that converts molasses and sugarcane juice from the mill into high-grade neutral ethyl alcohol.

What to watch

• Financial transparency. San Carlos is listed but its audited financials are not easily accessible to outside investors. Greater disclosure — or a move to quarterly reporting — would be the single biggest upgrade to the investment case.
• Sugar price and climate risk. Irregular rainfall cut the 2023 harvest season nearly in half. El Niño cycles are a structural risk for a company whose entire output depends on field conditions in coastal Guayas.
• Energy diversification. The company has invested more than $70 million across two phases of its electricity cogeneration programme. If Ecuador’s grid tariffs for renewable power remain attractive, this second revenue stream could meaningfully reduce dependence on sugar prices.
• Succession. With a board president in post since 1980 and a general manager since 1971, leadership transition is an eventual certainty — and one the company has not publicly addressed.
• US export quota. Ecuador’s US sugar quota for 2024–2025 stands at 44,178 tonnes — a hard ceiling on the most lucrative export market and a number to track in each annual trade negotiation.
