Michael E. Jesanis reported a change in beneficial ownership of NiSource Inc. common stock on a Form 4 filed July 15, 2026, covering an event dated July 13, 2026. The filing reports a transfer of NiSource common shares from an indirectly held form of ownership to direct ownership by the reporting person. The reported action was not described as an open-market purchase or sale. The filing’s explanatory note states that the transfer was “exempt from Section 16 reporting under Rule 16a-13,” a rule generally used for changes in the form of beneficial ownership that do not alter the insider’s underlying economic interest. As a result, the filing indicates a change in how the shares are held rather than a new acquisition or disposition for cash consideration. The document also notes that the reported ownership amount includes restricted stock units, or RSUs, received under dividend-equivalent provisions of prior RSU awards. Those dividend-equivalent RSUs remain subject to the same vesting conditions as the underlying RSUs, meaning they do not represent immediately unrestricted shares unless and until the related RSUs vest. The provided filing text does not disclose the number of shares transferred, any transaction price, a transaction code, or the insider’s total ownership after the transaction. The filing was signed on July 15, 2026, by Ashley Bancroft as attorney-in-fact for Jesanis.
