(PRESS RELEASE) LUXEMBOURG, 20-Jan-2026 — /EuropaWire/ — The Luxembourg Stock Exchange has acquired the ESG data analytics unit of Luxembourg-based fintech Tetrao International, strengthening its position as a leading reference point for sustainable bond data and reinforcing its long-term strategy in sustainable finance. The transaction enhances LuxSE’s ability to collect, structure, and deliver high-quality ESG data at scale, supporting investors’ growing need for reliable and transparent information.

The acquired business line specializes in extracting large volumes of sustainable bond data points from a wide range of sources using AI-powered technology. Through this acquisition, LuxSE gains direct oversight of the data collection process underpinning its sustainable bond data services, ensuring consistency, accuracy, and strategic alignment with market needs. The move builds on a long-standing collaboration between LuxSE and Tetrao, which has supported the development of LuxSE’s sustainable bond data offering for several years.

As part of the transaction, Tetrao’s experienced ESG data analytics team will join the LuxSE Group and continue to support the Luxembourg Green Exchange (LGX) by extracting and collecting sustainable bond data for the LGX DataHub. The team will leverage the proprietary tools, AI-driven technologies, and specialized expertise developed by Tetrao, while Tetrao International will remain a key technology provider to the LuxSE Group and continue operating independently.

Tetrao’s technology combines machine learning, generative AI large language models, and computer vision to automate the identification, reading, and understanding of complex information from documents and websites. These capabilities are integrated with human expertise and fully auditable processes to ensure high data quality standards. This large-scale data collection approach has been instrumental in powering the LGX DataHub, which today provides up to 200 data points across more than 23,000 green, social, sustainability, and sustainability-linked bonds, covering nearly the entire global universe of listed sustainable bonds.

The acquisition represents the next phase in a partnership that began with LuxSE’s minority investment in Tetrao in 2021. By bringing the ESG data analytics unit in-house, LuxSE aims to further strengthen its data services and explore opportunities to expand into new areas of sustainable finance data, while Tetrao continues to develop new AI-enabled services under the leadership of its founder and CEO, Christian Gillot. The transaction is expected to close by the end of February, subject to regulatory approvals.
