Equity
Holders of shares of our common stock are entitled to receive dividends when, as, and if declared by the Board out of funds legally available. The policy of the Board has been to declare cash dividends on a quarterly basis payable on or about the 20th day of February, May, August and November. We have certain debt covenants that could restrict our ability to pay dividends or potentially limit the amount of dividends we could pay in order to maintain compliance with these covenants. Refer to Note 8, "Long-Term Debt," for more information. As of December 31, 2025, these covenants did not restrict our ability to pay dividends or the amount of dividends that were available to be paid.
There is no preferred stock outstanding as of December 31, 2025.
Common and preferred stock activity for 2025, 2024 and 2023 is described further below.
Details of our 2024 ATM program are summarized below:
In February 2024, we entered into eight separate equity distribution agreements providing for the sale of up to an aggregate of $900.0 million of our common stock.

In February 2025, we executed a forward sale agreement, which allowed us to issue a fixed number of shares at a price to be settled in the future. The forward purchaser under our forward sale agreement borrowed 2,000,000 shares from third parties, which the forward purchaser sold, through its affiliated agent, at a weighted average price of $40.10 per share. In September 2025, we settled the forward sale agreement in shares for $80.0 million, based on a net price of $40.02 per share.

In October 2025, with the commencement of our 2025 ATM program discussed below, we terminated the equity distribution agreements entered into in February 2024 in connection with the 2024 ATM program.

Details of our 2025 ATM program are summarized below:

In October 2025, we entered into eleven separate equity distribution agreements providing for the sale of up to an aggregate of $1.5 billion of our common stock.

In October 2025, we executed a direct sale agreement of 1,195,029 shares at a price of $41.84 resulting in net proceeds of $49.6 million received in November 2025.

In October 2025, we executed a forward sale agreement, which allows us to issue a fixed number of shares at a price to be settled in the future. The forward purchaser under our forward sale agreement borrowed 2,390,057 shares from third parties, which the forward purchaser sold, through its affiliated agent, at a weighted average price of $41.84 per share. We may settle the forward sale agreement in shares, cash or net shares by October 2026. Had we settled all the shares under the forward sale agreement at December 31, 2025, we would have received approximately $99.7 million, based on a net price of $41.73 per share.

As of December 31, 2025, the 2025 ATM program inclusive of the forward sale agreement had approximately $1.35 billion of equity capacity available. The 2025 ATM program expires in December 2028.

Series A Preferred Stock. During 2023, there were $28.25 dividends declared per share for the Series A Preferred Stock. There were no dividends declared per share for the Series A Preferred Stock during 2024 and 2025.
In June 2023, we redeemed all 400,000 outstanding shares of Series A Preferred Stock for a redemption price of $1,000 per share or $400.0 million in total.

Series B and B-1 Preferred Stock. During 2024 and 2023, dividends declared per share for the Series B Preferred Stock were $406.25 and $1,625.0, respectively. There were no dividends declared per share for the Series B Preferred Stock during 2025.
In March 2024, we redeemed all 20,000 outstanding shares of Series B Preferred Stock for a redemption price of $25,000 per share and all 20,000 outstanding shares of Series B-1 Preferred Stock for a redemption price of $0.01 per share or $500.0 million in total. Following the redemption, dividends ceased to accrue on the shares of Series B Preferred Stock, shares of the Series B Preferred Stock and Series B-1 Preferred Stock were no longer deemed outstanding and all rights of the holders of such shares of Series B Preferred Stock and Series B-1 Preferred Stock terminated. In conjunction with the redemption, we recorded a $14.0 million preferred stock redemption premium, calculated as the difference between the carrying value on the redemption date of the Series B Preferred Stock and Series B-1 Preferred Stock and the total amount of consideration paid to redeem, which was recorded as a reduction to retained earnings during the first quarter of 2024. We did not recognize an excise tax liability under the IRA in connection with this redemption as we issued common stock in 2024 in excess of the fair value of the Series B Preferred Stock and Series B-1 Preferred Stock redeemed.
In March 2024, we filed a Certificate of Elimination to our Amended and Restated Certificate of Incorporation with the Secretary of State of Delaware to eliminate from the Amended and Restated Certificate of Incorporation all matters set forth in the Certificate of Designations with respect to the Series B Preferred Stock and the Certificate of Designations with respect to
the Series B-1 Preferred Stock. As a result, the 20,000 shares that were previously designated as Series B Preferred Stock and the 20,000 shares that were previously designated as Series B-1 Preferred Stock were returned to the status of authorized but unissued shares of preferred stock, par value $0.01 per share, without designation as to series. The Certificate of Elimination does not change the total number of authorized shares of capital stock of NiSource or the total number of authorized shares of preferred stock. We voluntarily delisted the preferred stock from the New York Stock Exchange in March 2024.

Equity Units. In December 2023, we issued 33,898,837 shares of our common stock under the purchase contract component of the Corporate Units. As of December 2023, each holder of Corporate Units was deemed to have automatically delivered to us the related Series C Mandatory Convertible Preferred Stock that were components of the Corporate Units in full satisfaction of such holder’s obligations under the related purchase contract, and all 862,500 shares of Series C Mandatory Convertible Preferred Stock were returned to the status of authorized but unissued preferred stock, par value of $0.01 per share, without designation as to series. We voluntarily delisted the Corporate Units from the New York Stock Exchange in December 2023.

Noncontrolling Interest in Consolidated Subsidiaries. As of December 31, 2025 and 2024, NIPSCO and tax equity partners have completed their cash contributions into the Indiana Crossroads Wind, Rosewater, Indiana Crossroads Solar and Dunn's Bridge I JVs. Earnings, tax attributes and cash flows are allocated to both NIPSCO and the respective tax equity partners in varying percentages by category and over the life of the partnership. The tax equity partner's contributions, net of these allocations, is represented as a noncontrolling interest within total equity on the Consolidated Balance Sheets. Refer to Note 4, "Noncontrolling Interests," for more information.
In December 2023, we consummated the closing of the NIPSCO Minority Interest Transaction and issued a 19.9% equity interest in NIPSCO Holdings II LLC to BIP in exchange for a capital contribution of $2.16 billion in cash. Transaction costs and deferred tax impacts of $54.7 million and $63.5 million, respectively, were recorded during the period ending December 31, 2023.
