Unipar Carbocloro S.A

What it is

Founded in 1969 as União Participações Industriais Ltda., Unipar pioneered petrochemical production in the São Paulo region before transforming into the focused chlorine-and-soda business it is today. In 2013, it acquired the remaining shares of Carbocloro from Occidental Petroleum, creating the current company and cementing its position as the largest such producer in South America.

In 2016 it bought Solvay Indupa S.A.I.C., expanding operations into Argentina and reinforcing its position in the soda, chlorine, and PVC markets. Plants operate in Santo André and Cubatão in Brazil, and at Bahía Blanca in Argentina.

Who owns it

The main shareholder is Vila Velha S.A., the Geyer family’s holding vehicle, which controls 51.1% of the voting capital. Insiders in total hold about 82.9% of the company’s shares (EODHD), leaving a relatively thin public float; state development bank BNDESPAR holds a meaningful minority stake alongside a liquid free float held by domestic and global asset managers.

Who runs it

Bruno Soares Uchino chairs the board. Rodrigo Cannaval is CEO and Alexandre Jerussalmy is CFO and investor-relations director.

On the finance side, senior planning executive Sergio brings 37 years in the chemical and petrochemical sector, all of them at Unipar.

The money, in plain words

Revenue fell 5.3% from 2024 to 2025, to R$5.14 billion (~US$997M), after rising 10.9% the year before — the chemical cycle, not a structural problem (our calculation). The company keeps about 7–10 cents of profit from every real of sales — a net margin that slid from a peak of 16.1% in 2023 to 9.5% in 2025 as global chlorine and PVC prices weakened (our calculation).

For every real shareholders have put in, Unipar earns about 16 back annually — a return on equity of 16.2%, solid for a commodity chemicals producer. The shares trade at about 19 times earnings (a price-to-earnings ratio of 19.0×), which prices in a recovery without demanding perfection.

Debt is the main number to watch: after its largest-ever investment programme, Unipar carries R$3.53 billion (~US$685M) of gross debt against only R$520M (~US$101M) of cash — net debt of roughly R$3.0 billion (~US$583M) (our calculation). Leverage closed 2025 at 2.2 times operating earnings, with average debt maturing in 73 months — well spread out in time.

What it is doing now

The new chlor-alkali plant in Camaçari, Bahia, reached full capacity, while the mercury phase-out upgrade at Cubatão progressed on schedule. The new membrane-cell technology at Cubatão will cut energy consumption by 18% and reduce CO₂ emissions, lifting both earnings and the company’s environmental credentials.

By the fourth quarter of 2025, Unipar was generating 68% of its Brazilian electricity consumption from its own renewable sources — wind and solar farms built through joint ventures. It returned to profit in Q1 2026, posting net income of R$37 million (US$7 mn) after a loss in the prior quarter, though low global prices for caustic soda and PVC remain a drag.

What to watch

• Commodity prices: International PVC prices fell 13% in 2025 and import competition reached historical highs — any recovery in global chemical pricing flows almost directly into Unipar’s margins.
• Argentina: The PVC market there remains weak under macroeconomic reform pressure, a persistent drag on the Argentine subsidiary’s contribution.
• Debt reduction: Capital spending is expected to fall sharply in 2026 after the record investment cycle, which should free cash to pay down the R$3.0 billion (US$582 mn) net debt position (our calculation).
• Dividend restart: The structured data shows a 0% yield today; with the investment cycle complete and cash flow rising, a return of distributions is the most natural next signal for shareholders to watch.
