MERRILLVILLE, Ind., May 05, 2026--(BUSINESS WIRE)--NiSource Inc. (NYSE: NI), one of the largest fully regulated utility companies in the United States, has received two honors recognizing its leadership in sustainability, based on third-party assessments of the company’s long-term economic, environmental and social performance. S&P Dow Jones Indices, a global index provider, named NiSource to its annual Dow Jones Best-in-Class Indices (DJ BIC) for the 12th consecutive year. Formerly known as the Dow Jones Sustainability Indices (DJSI), DJ BIC are float-adjusted, market-capitalization-weighted indices that track equity markets using a sustainability best-in-class selection process. MSCI also reaffirmed NiSource’s AAA ESG rating for the fifth consecutive year. This rating measures a company’s resilience to long-term, industry-specific sustainability risks using a rules-based methodology. MSCI analysts research and rate companies based on their exposure to and management of these risks relative to peers. "These recognitions of our commitment to sustainable practices in our daily operations are greatly appreciated," said Melody Birmingham, NiSource’s executive vice president and group president for utilities. "It reaffirms our business principles, acknowledges our employees for their hard work and dedication, and signals that our focus on sustainable practices is among the best in the industry." DJ BIC reflects performance across a broad set of sustainability criteria used in S&P Global’s Corporate Sustainability Assessment, which evaluates how companies manage long-term risks and opportunities. The indices represent the top 20-percent of the largest 600 North American companies in the Broad Market Index and are designed to help investors identify organizations that lead their industries on sustainability-related practices. MSCI ESG Ratings are used by many institutional investors to compare how well companies manage key industry-specific ESG risks and to inform portfolio construction and stewardship activities, including the publication of an annual Sustainability Report. An AAA rating is MSCI’s highest designation. About NiSource NiSource Inc.
