Lupatech S.A

What it is

Lupatech’s story begins on 8 August 1980, when Nestor Perini and Gercino Schmitt opened a small precision foundry called Microinox in Caxias do Sul, in the southern state of Rio Grande do Sul. Over the following years the business grew into a holding group, eventually specialising in industrial valves and oil-and-gas equipment under the Lupatech name.

Today the company runs two lines: a Products segment — mainly valves for industry and oil and gas, plus anchoring ropes for production platforms — and a Services segment covering well intervention, pipe coating, and inspection. Its Valmicro and Mipel brands sell industrial valves to customers in chemicals, pharmaceuticals, food, paper, and oil and gas.

Who owns it

No single shareholder controls the company. The investment fund Arara Azul holds about 18.5% of the shares; individual investor José Maria de Oliveira e Silva holds 8.95%; and António Amaral Vilas Boas Neto holds 5.09% — leaving roughly 67.5% in the open market (free float).

Lupatech’s own bylaws acknowledge that control is exercised on a “diffuse basis” — meaning no owner has a commanding block, which is unusual for a Brazilian industrial company of this size and unusual for one in such financial stress. Insiders hold about 12.3% and institutional investors about 25.2%, per structured data.

Who runs it

Rafael Gorenstein serves as Chief Executive Officer (Diretor Presidente) and Investor Relations Director. Gorenstein holds a mechanical-aeronautical engineering degree from ITA, a master’s in electrical engineering from PUC-RJ, and an MBA from Imperial College London; he previously worked as a financial executive in investment banking and several large companies before acting as a restructuring consultant to Lupatech from January 2015.

Marcos Antônio Miola, who holds an MBA from Fundação Getúlio Vargas and has been with the company for 30 years, serves as an executive director overseeing industrial operations. Carlos Mario Calad Serrano, Superintendent of Capital Markets at state development bank BNDES, sits on the Board of Directors — a sign that the development bank remains a significant creditor presence in the company’s governance.

The money, in plain words

Revenue has collapsed. After reaching R$123.1 million (~US$23.9 million) in 2024, annual sales fell to R$52.1 million (~US$10.1 million) in 2025 — a drop of 57.7% in a single year (our calculation).

For every real of sales in 2025, the company lost R$1.16 (US$0.23)— a net margin of –115.6% (our calculation), a sign that operating costs and financial charges vastly exceed what the business earns.

The balance sheet is the core problem. As of September 2025 the company carried R$171 million (~US$33.2 million) in net debt — more than four times its entire market value.

Total debt stands at R$178.1 million (~US$34.6 million) against cash of just R$384,000 (~US$74,600), giving a net debt of R$177.8 million (~US$34.5 million) (our calculation). For every real that owners have put in — equity of R$74.5 million (~US$14.5 million) — the company lost R$1.59 (US$0.31)last year, a return on equity of –158.75%.

What it is doing now

In March 2026 Lupatech filed an emergency court injunction to protect itself from creditors, a legal step that precedes a formal restructuring — whether out-of-court or through full judicial protection. This comes barely three years after the company exited a previous judicial restructuring process — one in which it had already converted 85% of its then-debt into shares and closed its entire oil-services division, laying off 1,800 workers.

Just weeks before the court filing, Lupatech announced a supply contract with a private multinational for synthetic-fibre mooring ropes for an FPSO vessel to be installed in Brazil, worth approximately R$17 million (~US$3.3 million), with delivery set for the third quarter of 2026. The order is real but, set against the debt load, modest.

What to watch

• Creditor talks: the company has said it will decide between out-of-court or full judicial restructuring depending on how negotiations with creditors develop.
• Revenue recovery: a 58% revenue drop in one year suggests either lost contracts or an asset divestiture; clarity on what is left of the business is the key question for any investor.
• BNDES role: the state development bank BNDES, represented on the board, has historically been both a creditor and stabilising force — its posture in the new restructuring will matter enormously.
• Diffuse ownership risk: with no controlling shareholder and a market value of barely US$6.9 million, any dilutive capital raise could reshape the register dramatically.
