H2O America Announces Proposed Offering of Common Stock with a Forward Component

SAN JOSE, Calif., March 02, 2026 (GLOBE NEWSWIRE) -- H2O America (NASDAQ: HTO) (“HTO” or the “Company”) announced today that it has commenced an underwritten public offering of $550 million in shares of its common stock, par value $0.001 per share (the “Offering”), subject to market and other conditions. Of the $550 million in shares of common stock being offered, the Company expects to issue and sell directly approximately $150 million in shares to the underwriters in the offering, and the forward purchasers (as defined below) or their respective affiliates and/or agents expect to borrow from third parties and sell to such underwriters approximately $400 million in shares of common stock in connection with the forward sale agreements described below.

In connection with the Offering, the Company expects to grant the underwriters a 30-day option to purchase directly from the Company up to an additional $82.5 million in additional shares of its common stock on the same terms as the Offering.

In connection with the Offering, the Company expects to enter into forward sale agreements with JPMorgan Chase Bank, National Association, New York Branch and Wells Fargo Bank, National Association (or their respective affiliates), each in its capacity as a forward counterparty (the “forward purchasers”), pursuant to which the Company will agree to issue and sell to the forward purchasers (subject to the Company’s right to elect cash settlement or net share settlement under the forward sale agreements) an aggregate of $400 million in shares of its common stock at an initial forward price per share equal to the price per share at which the underwriters purchase shares in the Offering, subject to certain adjustments, upon physical settlement of the forward sale agreements. Each forward sale agreement provides for settlement on a settlement date or dates to be specified at the Company’s discretion on or prior to March 2, 2028. If the underwriters exercise their option to purchase additional shares of common stock in the Offering, the Company expects to issue and sell such shares directly to the underwriters.

The Company intends to use the net proceeds of the Offering from the sale of the shares of our common stock and upon settlement of the forward sale agreements, together with the net proceeds of certain debt financing, to finance the Quadvest Acquisition and to pay related fees and expenses and for general corporate purposes, which may include acquisitions, capital expenditures, share repurchases or debt repayment. However, the Offering is not conditioned on the consummation of the Quadvest Acquisition or any future debt financing. If for any reason the Quadvest Acquisition does not close, then the Company expects to use the net proceeds from this offering for general corporate purposes, which may include acquisitions, capital expenditures, share repurchases or debt repayment, and the Company will not have any obligation to repurchase any or all of the shares of our common stock sold in the Offering (if any).

J.P. Morgan and Wells Fargo Securities are acting as joint book-running managers and as representatives of the underwriters for the Offering. In connection with the offering, the Company will issue and sell shares to the underwriters to the extent that the forward purchasers (or their respective affiliates) do not borrow and sell such number of shares.

The offering is being made pursuant to an effective shelf registration statement filed with the Securities and Exchange Commission (the “SEC”). The offering is being made only by means of a prospectus supplement, including the accompanying base prospectus.
