ISS STOXX to Acquire Sustainability Index Provider, ECPI

ZUG (December 18, 2025) — STOXX Ltd., part of the ISS STOXX GmbH group of companies and a leading provider of benchmark and custom index solutions to institutional investors, today announced it has signed a definitive agreement to acquire Milan-based ECPI S.R.L., from Confluence Technologies. ECPI is an established and cutting-edge provider of sustainability indices, data, and analytics to the institutional investor community.

Since its founding in 1997, ECPI has focused on translating sustainability themes into investable solutions that are based on proprietary research models. ECPI today assists both asset owners and asset managers in developing sustainable investment solutions that range from investable indices to sustainability portfolio screening. ECPI’s index family reflects one of the broadest offerings in the market that are also time-tested, given the firm launched its first index in 2001 and is a pioneer in the space. ECPI now offers more than 60 indices ranging from global benchmark to thematic, strategy, and hedged indices, with equity and fixed income sustainability indices used by institutional investors for index-based investment products, risk and return analysis, compliance with sustainability mandates, and to define an investment universe. Upon completion, STOXX Ltd. will become benchmark administrator for the full portfolio of ECPI Indices.

“The addition of ECPI and its highly talented team of professionals underscores our continued commitment to delivering industry leading and differentiated sustainability index offerings to augment and strengthen our clients’ investment processes,” said Axel Lomholt, Head of Index at ISS STOXX. “As a global top 10 index provider, we’re pleased to be able to bring to a wider audience ECPI’s varied sustainability indices and broader offerings.”

ECPI’s sustainability solutions go beyond index offerings. Its proprietary research model focuses primarily on performance factors that determine issuers’ sustainability and intangible market value. ECPI research covers more than 6,800 issuers and maintains one of the world’s largest corporate sustainability databases. In addition, ECPI uses an objective, sector-based, best-practices approach to analyzing sustainability data of issuers with the objective of translating qualitative data into quantitative indicators, assigning to each issuer a score and a rating.

“Product innovation and the ability to respond rapidly to client needs with tailor made solutions are at the heart of ECPI’s success and qualities we will significantly build on as part of ISS STOXX,” said Lorenzo Pelizzola, VP, ECPI Index and ESG Research. “The ECPI team is pleased to be a part of ISS STOXX, in furtherance of our shared objective of providing institutional investors with world-class and cutting-edge sustainability indices, ratings, data, and related offerings.”
