Empresa Distribuidora Electrica Regional SA

What it is

EMDERSA generates, distributes, and sells electricity in Argentina; it was incorporated in 1997 and is registered in Buenos Aires City. It operates a network of high, medium, and low-voltage transmission lines, as well as hydroelectric and thermal generation plants.

The company is tiny by any measure: its entire stock market value is roughly $334,000 USD — less than a Buenos Aires apartment — which reflects both its distressed finances and near-zero free float.

Who owns it

Argentina’s commerce authority approved the deal by which Energía Riojana S.A. acquired 78.57% of EMDERSA’s shares from the previous holding company. The structured data confirms the current result: insiders hold 100% and institutional investors hold 0%, meaning no shares trade freely in practice.

Energía Riojana was created by the government of La Rioja province as a majority state-owned corporation (SAPEM), composed of the Provincial Government of La Rioja and the state entity La Rioja Telecomunicaciones SAPEM. EMDERSA is therefore effectively a provincial government asset wearing a stock-market listing.

Who runs it

The board of Energía Riojana — EMDERSA’s controlling parent — was led, following a December 2022 extraordinary assembly, by Jerónimo Quintela (born 1987, engineer, La Rioja) as president. No separate CEO or CFO for EMDERSA itself is disclosed in available sources; governance flows directly from the provincial parent.

The money, in plain words

For every peso EMDERSA collects in revenue, it loses roughly 54 cents before it is done — a net margin of –54.3%, catastrophic for any business. The return on equity of –204.7% is not a typo; it reflects the fact that shareholders’ equity is itself deeply negative, meaning the company’s debts exceed all its assets, the textbook definition of insolvency.

Revenue in the reported annual accounts grew about 39% from 2022 to 2023 (our calculation from structured data), but that headline figure is almost entirely explained by Argentina’s triple-digit inflation during that period — in real, inflation-adjusted terms, the business was shrinking. The company pays no dividend and has no reported price-to-earnings ratio because there are no earnings.

What it is doing now

Argentina’s national government, under President Milei‘s administration, has been pushing through sharp electricity tariff increases since late 2023 as part of a broader subsidy-reduction programme. The energy emergency declared by Decree 55 of December 2023 has been extended repeatedly, most recently through Decree 370 of May 2025, and the government has described continuing corrections to electricity prices as essential to rebalancing the economy.

For a regulated distributor like EMDERSA, higher tariffs are the only real path to solvency.

No material deal, refinancing, or leadership change specific to EMDERSA has been disclosed in available sources in the most recent period.

What to watch

• Tariff trajectory. Because the government sets the price EMDERSA may charge, every regulatory decision is an earnings event. A sustained move toward cost-reflective tariffs is the single biggest driver of whether losses narrow.
• Equity rehabilitation. With negative equity, EMDERSA cannot borrow on normal terms; any investment in infrastructure requires either a capital injection from its provincial parent or a tariff-funded cash flow turnaround.
• Provincial politics. Energía Riojana is a creature of La Rioja’s provincial government. A change in provincial administration, or a falling-out between La Rioja and the national government over energy subsidies, could directly alter how EMDERSA is managed and funded.
• Listing relevance. With 100% insider ownership and no free float, the Buenos Aires listing is a formality. Watch for any move to delist or restructure the share register.
