PLAN OF DISTRIBUTION (CONFLICTS OF INTEREST)

We have entered into an equity distribution agreement, dated as of December 19, 2025, which we refer to as the equity distribution
agreement, with the Managers, Forward Sellers and Forward Purchasers under which we may issue or sell shares of our common stock having an aggregate sales price of up to $1,500,000,000 over a period of time and from time to time. The sales, if any,
of shares of our common stock made under the equity distribution agreement, and to which this prospectus supplement relates, will be made in “at the market” offerings as defined in Rule 415 under the Securities Act of 1933, as amended
(the “Securities Act”), including sales made directly on the NYSE, the existing trading market for shares of our common stock, or sales made to or through a market maker or through an electronic communications network. In addition,
shares of our common stock may be offered and sold by such other methods, including privately negotiated transactions (including block transactions), as we and the applicable Managers or Forward Sellers agree to in writing.

We also may sell shares of our common stock to one or more of the Managers, as principal for their own accounts, at a price per share agreed
upon at the time of sale. If we sell shares of our common stock to one or more Managers, as principal, we will enter into a separate terms agreement with such Manager or Managers, and we will describe the agreement in a separate prospectus
supplement or pricing supplement.

The equity distribution agreement provides that, in addition to the issuance and sale of shares of our
common stock by us through the Managers, we may also enter into one or more forward sale agreements under master forward confirmations we enter into with the Forward Purchasers. In connection with any forward sale agreement, the relevant Forward
Purchaser will borrow from third parties and, through its affiliated Forward Seller, sell a number of shares of our common stock equal to the number of shares of our common stock underlying such forward sale agreement. In no event will the aggregate
number of shares of our common stock sold through the Managers or the Forward Sellers under the equity distribution agreement have an aggregate sales price in excess of $1,500,000,000.

We estimate that the total expenses of
