MERRILLVILLE, Ind. - NiSource Inc. (NYSE: NI) today announced, on a GAAP basis, net income available to common shareholders for the quarter ended March 31, 2026 of $510.7 million, or $1.06 of earnings per diluted share, compared to net income available to common shareholders of $474.8 million, or $1.00 of earnings per diluted share, for the same period of 2025.

NiSource also reported first quarter 2026 non-GAAP adjusted net income available to common shareholders of $509.6 million, or $1.06 of consolidated adjusted EPS, compared to consolidated non-GAAP adjusted net income available to common shareholders of $462.3 million, or $0.98 of adjusted EPS, for the same period of 2025. Schedule 1 of this press release contains a complete reconciliation of GAAP measures to non-GAAP measures. **

NiSource is reaffirming its 2026 non‑GAAP consolidated adjusted EPS guidance of $2.02-$2.07 and raising its consolidated compound annual growth rate (CAGR) with respect to non‑GAAP consolidated adjusted EPS to 9%-10% from 2026 through 2033.

**Non-GAAP Disclosure Statement

This press release includes financial results and guidance for NiSource with respect to adjusted net income available to common shareholders, base plan adjusted EPS and consolidated adjusted EPS, which are non-GAAP financial measures as defined by the SEC. Commencing in 2026, the company began to present base plan adjusted EPS and consolidated adjusted EPS. As presented, guidance with respect to base plan adjusted EPS, including annual base plan adjusted EPS growth, excludes, in addition to the items historically excluded from adjusted EPS, the impact of data center operations and development activities relating to provision of electric service to current and future data center or other large load customers. The company provides guidance regarding base plan adjusted EPS because it expects that the earnings from its data center operations and development activities will experience a different growth profile compared to the base plan adjusted EPS growth. Providing guidance with respect to base plan adjusted EPS growth, together with guidance regarding consolidated adjusted EPS growth, provides investors with the same information that management considers to evaluate the company’s ongoing business performance and provide greater transparency into the performance of different aspects of our business that are impacted by distinct trends and factors. Consolidated adjusted EPS represents base plan adjusted EPS together with adjusted EPS from our data center operations and development activities. The company includes these measures because management believes they permit investors to view the company’s performance using the same tools that management uses and to better evaluate the company’s ongoing business performance. With respect to guidance on base plan adjusted EPS and consolidated adjusted EPS, NiSource reminds investors that it does not provide a GAAP equivalent of its guidance on base plan adjusted EPS or consolidated adjusted EPS due to the impact of unpredictable factors such as fluctuations in weather, impact of asset sales and impairments and other unusual or infrequent items included in the comparable GAAP measures, which may be material. The company is not able to estimate the impact of such factors on the comparable GAAP measures and, as such, the company is not able to provide a reconciliation of its non-GAAP base plan adjusted EPS guidance or its non-GAAP consolidated adjusted EPS guidance to the comparable GAAP equivalents without unreasonable efforts.
