Global Water Resources Reports Second Quarter 2025 Results

PHOENIX, AZ – August 13, 2025 – Global Water Resources, Inc. (NASDAQ: GWRS), a pure-play water resource management company, reported results for the second quarter ended June 30, 2025. All comparisons are to the same year-ago period unless otherwise noted. The company will hold a conference call at 1:00 p.m. Eastern time tomorrow to discuss the results (see dial-in information below).

Q2 2025 Financial Highlights

•Total revenue increased 5.4% to $14.2 million, primarily due to organic connection growth, increased consumption and higher rates.

•Net income decreased to $1.6 million or $0.06 per share from $1.7 million or $0.07 per share. One of the primary drivers of this decline is due to the company’s capital improvement plan, which has resulted in a related increase in depreciation expense.

•Adjusted EBITDA, a non-GAAP term, increased 2.1% to $6.9 million (see definition of adjusted EBITDA and its reconciliation to GAAP, below).

•Extended maturity date of revolving credit facility to May 18, 2027 and increased principal amount available for borrowing from $15 million to $20 million.

•Declared three monthly cash dividends of $0.02533 per common share or $0.30396 per common share on an annualized basis.

Q2 2025 Operational Highlights

•Total active service connections at June 30, 2025 increased 3.8% to 65,639.

•Water consumption increased 8.2% to 1.2 billion gallons.

•Invested $20.2 million in infrastructure projects to support existing utilities and continued growth.

•The Arizona Corporation Commission (ACC) issued Decision No. 80695 for Global Water – Farmers Water Company, Inc. (GW-Farmers). The new rates are expected to generate an approximately $1.1 million increase in annual revenue once fully phased in. GW-Farmers will implement the rate increase in three stages, which began on May 1, 2025.

Other Highlights

•In July, the company completed its previously announced acquisition of seven water systems from Tucson Water, the City of Tucson’s water utility. The assets were acquired at a value equivalent to approximately 1.05 times the current rate base of approximately $7.7 million and are expected to generate approximately $1.5 million in revenue annually.

•On July 1, 2025, the U.S. Census Bureau population projections estimated the City of Maricopa was the 6th fastest growing large city (population over 50,000) in the country, with a 2024 population increase of 7.4%. This demonstrates even faster population growth than 2023, which was 7.1%.

Management Commentary

“In Q2, our top-line growth was primarily driven by organic connection growth, increased consumption and successful rate case strategy,” commented Global Water Resources President and CEO Ron Fleming. “During the quarter, we received approval of our GW-Farmers general rate case, which started with 50% of the approved rate increase becoming effective on May 1, 2025, with subsequent increases to follow. The additional revenue will support our efforts to improve GW-Farmers for the benefit of its customers and the broader Sahuarita community.

“We are very pleased with the Arizona Department of Transportation’s recent decision to include State Route 347 improvements in its $11.6 billion five-year plan, which we believe is a major milestone for the region and a catalyst for sustainable growth. Specifically, as construction activity accelerates on State Route 347, we expect this could drive expanded residential and commercial development resulting in an increase in demand for water, wastewater and recycled water services throughout the City of Maricopa and all of western Pinal County.

“Looking ahead, we believe Arizona’s Senate Bill 1611, the new ‘ag-to-urban’ bill signed into law last month, will support water management, economic development, and housing accessibility in our areas when it becomes effective on September 26, 2025. According to the Arizona Department of Water Resources, up to 384,000 acres of agricultural land in the Phoenix and Pinal Active Management Areas are eligible for ag-to-urban conversion — an area with the potential to support over 1 million new homes.

“Our general rate case for GW-Santa Cruz and GW-Palo Verde is proceeding as planned, with testimony and a hearing expected to commence in the fourth quarter of 2025. This process will determine our go-forward customer rates for our two largest utilities around mid-2026. We are seeking approximately $6.5 million in additional net annual revenue above 2024 test year levels to maintain the high-quality water and wastewater services we provide.

“Until our current Pinal County utilities’ rate case is completed, the vast majority of our revenue is based on rates set from a 2019 test year. Further, based on the typical regulatory practice of allowing one year of post test year plant by the ACC, the capital investments we make in 2025 will be included in the current rate case. We expect appropriate rates that capture these items at the anticipated completion of the rate case. We remain confident in our ability over time to deliver a strong total return to our shareholders while delivering safe, reliable service and balancing customer affordability as we navigate rate cases, especially when considering all the highlights reported in this earnings release.

“We are optimistic that Arizona's strong economic outlook has the potential to support the growth of our organic connections. With employment expected to rise by 478,000 jobs through 2032—an annual growth rate of 1.4%, outpacing the national average—Arizona is on an upward trajectory. Last year alone, the state received $50 billion in investment commitments, with major contributions from industry leaders such as Taiwan Semiconductor, Intel, and Procter & Gamble. Just last quarter, TSMC announced an extra $100 billion expansion in Metro Phoenix, bringing its planned investment to $165 billion—the largest direct foreign investment in U.S. history. In addition, earlier this year, Apple announced plans to invest billions in Arizona. These unprecedented investment commitments are expected to significantly reshape the Metro Phoenix area.

“As the year advances, we aim to further extend the benefits of consolidation, regionalization, and proactive environmental management to the communities we serve. By executing our rate case strategy alongside our anticipation of ongoing organic growth, we believe we are well positioned for continued success over the long-term.”

Financial Summary

Revenue


	Three Months Ended				Favorable (Unfavorable)
	June 30,				2025 vs. 2024
	2025		2024		$		%
Water service	$	7,368	$	6,668	$	700	10.5	%
Wastewater and recycled water service	6,873		6,842		31		0.5	%
Total regulated revenue	14,241		13,510		731		5.4	%

Total revenue	$	14,241	$	13,510	$	731	5.4	%

The increase in regulated revenue for the three months ended June 30, 2025 was primarily attributable to the organic growth in active water and wastewater connections, increased water and recycled water consumption, higher rates for GW-Saguaro, resulting from the GW-Saguaro general rate case, effective July 2024 and January 2025, and higher

rates for GW-Farmers resulting from the GW-Farmers general rate case, effective May 1, 2025. The increased consumption was predominantly driven by the increase in active connections and higher usage from irrigation and construction customers. The increase in wastewater and recycled water service revenue was partially offset by $0.2 million in bill credits related to the company's Southwest Plant, which were effective beginning August 2024.

Total operating expenses	$	11,621	$	10,713	$	(908)	(8.5)	%

Operations and Maintenance

Higher personnel costs were primarily attributable to increased salaries and wages as a result of filling previously vacant positions as well as increased medical costs.

The increase in other operations and maintenance expenses was primarily driven by additional contracts with IT service providers and one-time costs related to wastewater disposal.

General and Administrative

The increase in other general and administrative expenses was primarily attributable to higher costs associated with various service providers.

Depreciation and Amortization

The increase for the three months ended June 30, 2025, as compared to the three months ended June 30, 2024 was substantially attributable to an increase in depreciable fixed assets as well as additional amortization from a new office lease in Pima County in December 2024.

Other Expense

Other expense totaled $0.4 million for the three months ended June 30, 2025, compared to $0.5 million for the same period in 2024. The decrease in other expense was substantially attributable to higher income associated with Buckeye growth premiums of $0.1 million that resulted from an increase in new meter connections in the area for the three months ended June 30, 2025 compared to the same period in 2024.

Net Income

Net income decreased $0.1 million or 6.8% to $1.6 million or $0.06 per share in the second quarter of 2025, compared to net income of $1.7 million or $0.07 per share in the second quarter of 2024.

Adjusted EBITDA

Adjusted EBITDA increased $0.1 million or 2.1% to $6.9 million in the second quarter of 2025, compared to $6.8 million in the same period in 2024.

Dividend Policy

The company recently declared a monthly cash dividend of $0.02533 per common share (or $0.30396 per share on an annualized basis), payable on August 29, 2025, to holders of record at the close of business on August 15, 2025.

Business Strategy

Global Water's near-term growth strategy involves increasing service connections, improving operating efficiencies, and increasing utility rates as approved by the ACC. The company plans to continue aggregating water and wastewater utilities through strategic acquisitions and entity consolidation, which is expected to enable the company and its customers to realize the benefits of consolidation, regionalization, and environmental stewardship.

Connection Rates

As of June 30, 2025, active service connections increased by 2,383 or 3.8% to 65,639 compared to 63,256 at June 30, 2024, with the increase primarily due to organic growth in the company’s service areas.

Arizona’s Growth Corridor: Positive Population and Economic Trends

The company continues to experience organic growth exhibited through its year-over-year organic increase in active connections (i.e., exclusive of acquisition related growth) of 3.8% as of June 30, 2025. According to the 2024 U.S. Census estimates, the Phoenix metropolitan statistical area (MSA) is the 10th largest MSA in the U.S. and had an estimated population of 5.2 million, an increase of 7.0% over the 4.8 million people reported in the 2020 Census. Growth in the Phoenix MSA continues as a result of its excellent weather, large and growing universities, a diverse employment base, and low taxes. The Employment and Population Statistics Department of the State of Arizona predicts that the Phoenix metropolitan area will have a population of 5.8 million people by 2030 and 6.5 million by 2040.

The company’s organic growth continues to be heavily influenced by the substantially lower cost of housing in the City of Maricopa as compared to other areas in the Phoenix MSA. As of June 2025, the median home sales price was nearly 30% lower in the City of Maricopa than in the City of Phoenix. The company is monitoring potential effects on its operations due to changes in the macroeconomic environment, such as the impacts of tariffs on its operational costs and construction work in progress, as well as new home construction in the company’s service areas. The company continues to expect a positive long-term outlook based on forecasted performance of job growth and construction in the Phoenix MSA housing market.

Although the Phoenix MSA has experienced a decrease in both single family and multi-family permits issued in the first half of 2025 as compared to same year ago period due to external factors and macroeconomic challenges, including, among other things, uncertainty related to tariffs, management believes the company is well-positioned to benefit from the long-term growth expected in the Phoenix MSA due to the availability of lots and existing infrastructure in place within its service areas.

Use of Non-GAAP Measures

This press release contains certain financial measures that are not recognized measures under accounting principles generally accepted in the United States of America (“GAAP”), including EBITDA, adjusted EBITDA, and adjusted net income. EBITDA is defined for the purposes of this press release as net income before interest, income taxes, depreciation, and amortization. Adjusted EBITDA is defined as EBITDA excluding the gain or loss related to (i) nonrecurring events; (ii) restricted stock expense related to awards made to employees and the board of directors and (iii) disposal of assets, as applicable. Adjusted net income reflects net income excluding (i) the amortization related to ICFA intangible assets; and (ii) the tax effect of this item, as applicable.

Management believes that EBITDA, adjusted EBITDA, and adjusted net income are useful supplemental measures of our operating performance and provide our investors meaningful measures of overall corporate performance. EBITDA is also presented because management believes that it is frequently used by investment analysts, investors, and other interested parties as a measure of financial performance. Adjusted EBITDA and adjusted net income are also presented because management believes that they provide our investors additional measures of our recurring core business. However, non-GAAP measures do not have a standardized meaning prescribed by GAAP, and investors are cautioned that non-GAAP measures, such as EBITDA, adjusted EBITDA, and adjusted net income, should not be construed as an alternative to net income or loss or other income statement data (which are determined in accordance with GAAP) as an indicator of our performance or as a measure of liquidity and cash flows. Management's method of calculating EBITDA, adjusted EBITDA, and adjusted net income may differ materially from the method used by other companies and accordingly, may not be comparable to similarly titled measures used by other companies. A reconciliation of EBITDA, adjusted EBITDA, and adjusted net income to net income, the most comparable GAAP measure, is included in the schedules attached to this press release.

Cautionary Note Regarding Forward-Looking Statements

Certain statements in this press release and the related conference call include certain forward-looking statements which reflect the company's expectations regarding future events.

These statements are based on our current beliefs or expectations and are inherently subject to a number of risks, uncertainties, and assumptions, most of which are difficult to predict and many of which are beyond our control. Actual results may differ materially from these expectations due to changes in political, economic, business, market, regulatory, and other factors. Factors that may also affect future results are disclosed under the headings “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our filings with the Securities and Exchange Commission (the "SEC"), which are available at the SEC's website at www.sec.gov.
