Equity Equity
On May 14, 2025, the Company entered into an equity distribution agreement to sell shares of its common stock having an aggregate gross sales price of up to $350.0 million (2025 Equity Agreement) from time to time, depending on market conditions, through an at-the-market equity program over the succeeding three years. Pursuant to the terms of the 2025 Equity Agreement, the Company may enter into forward sale agreements with forward counterparties. The Company intends to use the net proceeds from equity sales, after deducting commissions and offering expenses, for general corporate purposes, which may include working capital, construction and acquisition expenditures, investments and repurchases, and redemptions of securities. During the three months ended June 30, 2026, the Company sold 1,972,357 shares of common stock through its at-the-market equity program and raised proceeds of $88.0 million, net of $0.9 million in commissions paid. During the six months ended June 30, 2026, the Company sold 2,106,557 shares of common stock through its at-the-market equity program and raised proceeds of $94.1 million, net of $1.0 million in commissions paid. As of June 30, 2026, approximately $253.4 million remains available for sale under the at-the-market equity program.
During the three and six months ended June 30, 2025, the Company did not utilize the at-the-market equity program.
