These risks, uncertainties and other factors may cause the actual results, performance or achievements of H2O America to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements.

Results for a quarter are not indicative of results for a full year due to seasonality and other factors. In addition, actual results, performance or achievements are subject to other risks and uncertainties that relate more broadly to our overall business, including those more fully described in our filings with the SEC, including our most recent reports on Form 10-K, Form 10-Q and Form 8-K. Forward-looking statements are not guarantees of future performance, and speak only as of the date made, and we undertake no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by law.

In May 2025, the Company changed the corporate name from SJW Group to H2O America. We will not distinguish between our prior and current corporate name and will refer to our current corporate name throughout this quarterly report on Form 10-Q. As such, unless expressly indicated or the context requires otherwise, the terms “H2O America,” “company,” “we,” “us,” and “our” in this document refer to H2O America, a Delaware corporation, and, where appropriate, its subsidiaries.
