SAN JOSE, Calif., July 27, 2026 (GLOBE NEWSWIRE) -- H2O America (NASDAQ: HTO) today reported financial results for the second quarter of 2026.

“Our strong second quarter results have our company in an excellent position midway through 2026 to deliver on our full year guidance and we remain committed to our longer-term financial targets,” said chair and chief executive officer, Andrew F. Walters. “During the second quarter, our teams made substantial progress towards obtaining Texas regulatory approval for the regulated portion of the Quadvest acquisition. In addition, a great deal of thought and effort went into the general rate cases that we filed in Connecticut and Maine seeking the recovery of more than $180 million of combined investments that are not yet recognized in rates. The regulatory and operational focus of our team is unwavering as we execute on our growth strategy while providing our customers and the communities that we are honored to serve with the high quality service they deserve. The hard work and shared passion that my fellow partners here at H2O America exhibit each and every day make it all possible and I could not be more proud.”

Second Quarter 2026 Operating Results

Net income prepared in accordance with GAAP for the second quarter ended June 30, 2026 was $26.6 million, an 8% increase compared to $24.7 million in the same quarter last year. GAAP diluted EPS for the quarter of $0.62 decreased versus $0.71 in the prior year quarter.

Adjusting for costs associated with merger, acquisition and integration activities and non-utility real estate transactions, H2O America's adjusted net income (non-GAAP)¹ in the second quarter of 2026 was $30.7 million, an increase of 17% compared to $26.2 million in the prior year quarter. Adjusted diluted EPS (non-GAAP) for the quarter of $0.72 slightly decreased versus $0.75 in the prior year quarter.

For both GAAP and adjusted results, while our underlying net income grew during the 2026 period, this was more than offset by the higher share count as a result of leveraging our at-the-market (ATM) program throughout 2025 and our common stock issuance in early March of 2026. A full reconciliation of GAAP net income to adjusted net income for the quarter ended June 30, 2026 is included in the tables at the end of this news release.

Operating revenue for the second quarter was $210.5 million, compared to $198.3 million for the same quarter last year, a 6% increase. The increase was driven primarily by rate increases of $14.5 million across all of our states but primarily in California and Connecticut. This was partially offset by a decrease of $1.7 million due to regulatory mechanism adjustments.

Operating expenses for the second quarter were $167.7 million, up 9% compared to $154.4 million for the same quarter last year. This change in operating expenses primarily reflects:

• An increase in water production expenses of $4.6 million compared to the same quarter last year primarily attributable to increases in average per unit costs for purchased water and groundwater extraction, partially offset by lower usage.
• An increase in depreciation and amortization expense of $3.4 million associated with utility plant additions placed in service compared to the same quarter last year.
• An increase in all other operating expenses of $5.3 million compared to the same quarter last year primarily attributable to a net increase in general and administrative expenses driven by increased merger and acquisition costs, increased outsourced services costs, increased employee-related costs and increased maintenance agreement costs.
  
  

The effective consolidated income tax rates for the second quarter of 2026 and 2025 were approximately 13% and 16%, respectively. The lower effective tax rate for the second quarter of 2026 was primarily due to higher flow through tax benefits.

Year-to-Date Operating Results

Net income prepared in accordance with GAAP for the six months ended June 30, 2026 was $45.6 million, an 11% increase compared to $41.2 million in the same period of 2025. GAAP diluted EPS for the six months of $1.12 decreased versus $1.20 in the same period last year.

H2O America's adjusted net income (non-GAAP) for the six months ended June 30, 2026 was $50.1 million, an increase of 17% compared to $42.9 million in the same period last year. Adjusted diluted EPS (non-GAAP) for the first six months of 2026 of $1.23 slightly decreased versus $1.25 in the same period last year.

For both GAAP and adjusted results, while our underlying net income grew during the 2026 period, this was more than offset by the higher share count as a result of leveraging our ATM program throughout 2025 and our common stock issuance in early March of 2026. A full reconciliation of GAAP net income to adjusted net income for the six months ended June 30, 2026 is included in the tables at the end of this news release.

Operating revenue for the first six months of 2026 was $393.8 million compared to $365.9 million for the same period last year, an 8% increase. The increase was driven primarily by rate increases of $26.4 million, primarily in California, Connecticut, and Texas, as well as higher customer usage of $2.0 million. This was partially offset by a decrease of $1.6 million due to regulatory mechanism adjustments.

Operating expenses for the first six months of 2026 were $313.6 million, up 10% compared to $286.1 million for the same period last year. This change in operating expenses primarily reflects:

• An increase in water production expenses of $12.1 million compared to the same period last year primarily attributable to increases in average per unit costs for purchased water and groundwater extraction, increases in water production balancing and memorandum accounts, primarily relating to the Full Cost Balancing Account ("FCBA"), and higher customer usage, partially offset by decreases in costs as a result of increased availability of surface water.
• An increase in depreciation and amortization expense of $7.4 million associated with utility plant additions placed in service compared to the same period last year.
• An increase in all other operating expenses of $8.0 million compared to the same period last year primarily attributable to a net increase in general and administrative expenses driven by higher merger and acquisition costs, outsourced services, insurance, and maintenance agreement costs.
  
  

The effective consolidated income tax rates for the first six months of 2026 and 2025 were approximately 14% and 16%, respectively. The lower effective tax rate for the six months of 2026 was primarily due to higher flow through tax benefits.

Capital Expenditures

Through June 30, 2026, H2O America has invested $206.9 million² in infrastructure. We continue to plan to invest $483 million² in capital for the full year 2026 (excluding the impact of Quadvest) and a total of $2.7 billion² over the 2026-30 period (including the impacts of Quadvest and Cibolo Valley) to build and maintain our water and wastewater operations, subject to regulatory approvals and availability of funding.

Quadvest Acquisition Update

Texas Water Company (TWC) and Texas Water Operation Services continue to progress through the regulatory process for their previously announced $540 million acquisition of Quadvest.

On July 9, 2026, the Public Utility Commission of Texas (PUCT) Staff recommended that the proposed transaction should be allowed to proceed without a public hearing as part of the pending Sale-Transfer-Merger (STM) application docket. The Quadvest STM procedural schedule outlines August 26, 2026 as the 120-day statutory deadline for the PUCT to approve the sale or require a hearing. Based on the aforementioned milestones, we anticipate closing the transaction around the end of the third quarter or early fourth quarter of 2026.

The STM application requests approval of TWC’s acquisition of the Quadvest, L.P. assets and certification of the value of the ratemaking rate base, as determined in accordance with Texas’ fair market value (FMV) statute, at TWC’s $483.6 million purchase price.

Quadvest continues to achieve its anticipated customer growth. Total active connections grew 10%, or 5,400 connections, during the first six months of 2026 after growing 16%, or 7,400 connections, in 2025. This brings Quadvest's total active connections to 59,800 as of June 30, 2026. In addition, despite converting 5,400 connections to active, the number of connections under contract and pending development at June 30, 2026 grew by 11,900, to nearly 99,000, since December 31, 2025. As previously communicated, we expect the addition of Quadvest to drive Texas from 8% of our consolidated customer base at year-end 2025 to 26% by 2029.

2026 and Long-Term EPS Guidance

The company affirms its standalone 2026 adjusted diluted EPS guidance of $3.08-$3.18¹.

2026 guidance excludes the impacts of the pending Quadvest and Cibolo Valley acquisitions and the financing thereof, which will be initially dilutive to EPS prior to our ability to implement new rates reflecting the ratemaking rate bases of the acquired assets resulting from a consolidated Texas general rate case that we expect to file in early 2027.

We also affirm our non-linear, long-term adjusted diluted EPS CAGR target of 6-8%, anchored off of 2025's adjusted diluted EPS of $2.99. The long-term 6-8% CAGR target reflects a long-term, sustainable organic growth rate that is supported by elevated capital investment needs for decades to come and does not factor in any potential M&A opportunities beyond Quadvest and Cibolo Valley.

Further, we continue to expect to deliver a non-linear adjusted diluted EPS CAGR at or above the top end of the 6-8% range over the 2026-30 period.

Our guidance is subject to risks and uncertainties, including, without limitation, those factors outlined in the Forward-Looking Statements of this release and the Risk Factors section of the company’s annual and quarterly reports filed with the Securities and Exchange Commission.

Rate Activity and Regulatory Highlights

California

On April 10, 2026, San Jose Water Company ("SJWC") filed with the California Public Utilities Commission (CPUC) for cost recovery of its planned PFAS compliance program. Specifically, SJWC seeks authorization to design and construct an ion exchange PFAS remediation system at its Williams Station as well as to track the associated capital and operation and maintenance costs for recovery. SJWC estimates the total capital cost of the project to be approximately $176 million. If approved, SJWC would adjust rates via annual rate base filing offsets.

On June 30, 2026, the CPUC approved Advice Letter 629A, which requested an $8.4 million increase in revenue on July 1, 2026 for SJWC's incremental $52.9 million of investments in its Advanced Metering Infrastructure (AMI) project.

Connecticut

On April 1, 2026, a Water Quality and Treatment Adjustment (WQTA) surcharge of $0.6 million, or 0.50%, became effective following Public Utilities Regulatory Authority (PURA) approval on March 18, 2026. Connecticut Water Company (CWC) submitted its first WQTA application on January 22, 2026 to recover the costs associated with in-progress or completed WQTA-eligible projects.

On April 1, 2026, a $2.7 million increase in annualized Water Infrastructure and Conservation Adjustment (WICA) revenues became effective for the recovery of $25.7 million in completed projects. PURA approved the filing in its entirety on March 25, 2026 which brought the cumulative WICA surcharge to 9.90%, collecting $12.1 million on an annual basis.

The 2025 Water Revenue Adjustment (WRA) mechanism surcharge of 5.70% became effective for the 12-month period beginning April 1, 2026. PURA approved CWC's WRA filing in its entirety on March 19, 2026. The mechanism reconciles 2025 revenues as authorized in CWC’s most recent general rate case as well as provides for recovery of certain amounts of compensation expenses as a result of achieving the PURA prescribed performance metrics in our last general rate case.

On May 11, 2026, CWC filed a general rate case application with the PURA requesting a $28.8 million increase in annual revenues for the recovery of the approximately $145 million of infrastructure investments made between its last rate case and the end of 2026 as that investment is not reflected in current rates. The test year will be the 12-month period ending December 31, 2025, for new rates to become effective February 2027.

Maine

On April 13, 2026, Maine Water Company (MWC) filed its first consolidated general rate case with the Maine Public Utilities Commission (MPUC) requesting a $9.5 million increase in annual revenues for the recovery of an anticipated $36 million of infrastructure investments not reflected in current rates using a test year ending December 31, 2025. New rates are expected to go into effect by the second quarter of 2027.

On May 1, 2026, the MPUC approved MWC's first consolidated Water Infrastructure Charge (WISC) application in its entirety and the new rates became effective immediately. MWC filed the $0.9 million WISC increase request on February 27, 2026.

Texas

On October 6, 2025, TWC filed an application with the PUCT to increase the system improvement charge (SIC) by $5.1 million for completed water and wastewater projects. A decision from the PUCT is expected in the second half of 2026.

On April 21, 2026, TWC filed the STM application for the acquisition of the Cibolo Valley wastewater treatment plant and associated collection systems, which serve more than 1,500 wastewater connections within TWC's existing water service area. We expect to close the transaction during the fourth quarter of 2026.

Dividend

On July 27, 2026, the Board of Directors of H2O America declared a quarterly cash dividend on common stock of $0.44 per share, payable on September 1, 2026, to shareholders of record at the close of business on August 10, 2026. The 2026 annualized dividend is expected to be $1.76 per share compared with $1.68 per share in 2025.

Dividends have been paid on H2O America’s and its predecessor’s common stock for more than 80 consecutive years, and the annual dividend amount has increased in each of the past 58 years, placing H2O America in an exclusive group of companies.

Non-GAAP Financial Measures

H2O America's net income and diluted EPS are prepared in accordance with GAAP and represent the earnings as reported to the Securities and Exchange Commission. Adjusted net income and Adjusted diluted EPS are non-GAAP financial measures representing GAAP earnings adjusted to exclude the effects of non-utility real estate transactions and costs associated with mergers, acquisitions and integration activities, if any. These non-GAAP financial measures are provided as additional information for investors to evaluate the performance of H2O America's business activities excluding these items. Management also believes these non-GAAP financial measures help investors and analysts better understand our actual results compared to our guidance on a non-GAAP basis. H2O America uses adjusted net income and/or adjusted diluted EPS as the primary performance measurements when communicating with analysts and investors regarding our outlook and results. Adjusted net income and Adjusted diluted EPS are also used internally to measure performance. However, these non-GAAP financial measures may be different from non-GAAP financial measures used by other companies, even when the same or similarly titled terms are used to identify such measures, limiting their usefulness for comparative purposes. Further, these non-GAAP financial measures should be considered as a supplement to the financial information prepared on a GAAP basis rather than an alternative to the respective GAAP financial measures.
