Tereos Açúcar e Energia S.A. operates within the governance framework of the Tereos Group — one of the world's largest sugar, starch, and bioenergy cooperatives, with more than 10,300 cooperative members.
Tereos' governance places cooperative members at the heart of strategy, combining operational efficiency with proximity to growers. A clear division of responsibilities between elected representatives and management supports long-term value for farmers, employees, and stakeholders across Thailand and Southeast Asia.
The Board of Directors, Cooperative Board, and Management Committee structure described below reflects the official Tereos Group governance model, as published in the Group's annual report and investor disclosures.
The Board of Directors manages all agricultural, industrial, commercial, and financial activities of the Tereos Group. It sets operational guidelines and strategy, and establishes remuneration for cooperative members on recommendation from the Cooperative Board. The Board comprises nine members elected from among Tereos' cooperative members, and may include up to two permanent independent directors with full participatory rights in an advisory capacity.
Chairman of the Board of Directors
Gérard Clay was elected Chairman of the Tereos Board of Directors on 23 June 2022, and re-elected in June 2023, 2024, and 2025. He had been Chairman of the Supervisory Board since December 2020. A key figure in the 2006 merger of Sucreries Distilleries des Hauts de France (SDHF) with Tereos, he is a sugar-beet grower in Bryas (Pas-de-Calais, France). His farm — producing sugar beet, potatoes, canned peas, and cereals — is affiliated with the Tereos sugar factory in Lilliers.

The Cooperative Board prepares decisions for the Board of Directors on agricultural, industrial, commercial, and financial activities related to cooperative members' crops within Tereos France UCA, Tereos Nutrition Animale UCA, and Tereos Starch & Sweeteners Europe. The Board comprises 18 members chosen from 134 Regional Councillors, supported by five activity commissions.
Agronomic standards, harvest logistics, and supply-chain sustainability for beet production — including operational rules for digging, tarping, and collection.
Management and development of potato-starch production collections, market outlook, and sustainability projects across the value chain.
Co-product valorisation, feed-market positioning, and operational rules for animal-nutrition activities within the cooperative perimeter.
Agronomic support, collection standards, and development of alfalfa-based products for animal nutrition and export markets.
Pilot projects on sustainable and low-carbon production, decarbonisation from upstream to downstream, and innovation in cooperative agriculture.
Regional Assemblies bring together cooperative members from each region each spring, after the financial year ends and before the Plenary General Meeting. Decisions — mainly on the election of representatives — follow cooperative principles of one member, one vote. Regional Assemblies share information on Tereos activities, financial results, and projects, and elect regional councillors who represent members at the Plenary General Meeting. Six regions elect 134 regional councillors in total, with one third of mandates renewed each year.
The Management Committee implements Board decisions on delegation from the Board of Directors. Led since 19 September 2023 by Olivier Leducq as Managing Director, it ensures the Group's strategy is understood and executed by operational and functional teams worldwide — including Tereos Açúcar e Energia's activities across Thailand and Southeast Asia.
