SPOKANE, Wash., Feb. 25, 2026 (GLOBE NEWSWIRE) -- Avista Corp. (NYSE: AVA) today reported net income based on GAAP of $193 million, or $2.38 per diluted share, compared to $180 million, or $2.29 per diluted share, in 2024. Non-GAAP utility earnings¹ were $207 million, or $2.55 per diluted share, compared to $187 million, or $2.38 per diluted share in 2024. Our utility results were driven by strong operational execution, constructive regulatory outcomes, customer load growth, and disciplined cost management.

CEO Perspective

“The core of our operations – our utility – is strong,” said Heather Rosentrater, President and CEO of Avista. “Our utility earnings were up from 2024, but were negatively impacted by the late-December Washington order regarding our exit from Colstrip. Throughout the year, our team remained focused on execution of our key initiatives. Outcomes from our recent request for proposal reinforce our utility strength and support our ability to continue delivering safe, reliable energy to the communities we serve and creating enduring value for our shareholders.”

Initiating 2026 Utility Earnings Guidance

Avista Corp. is initiating 2026 non-GAAP utility earnings guidance² with a range of $2.52 to $2.72 per diluted share. In 2026, a large industrial customer gave its notice of intent to return to procuring power independently in the power markets sooner than we expected. Our 2026 non-GAAP utility earnings guidance reflects a decrease of $0.12 per diluted share due to this departure.

Analysis of 2025 GAAP Earnings

2025 net income increased compared to 2024 primarily due to the effects of our general rate cases, customer growth and load growth. This increase in net income was partially offset by increased losses at our other businesses, as discussed below.

Analysis of 2025 Non-GAAP Utility Earnings

The following table presents the changes in non-GAAP utility earnings and non-GAAP utility earnings per diluted share for the fourth quarter and year ended Dec. 31, 2025, as compared to the respective periods in 2024. It also outlines the various after-tax factors that contributed to these changes (dollars in millions, except per-share data):

	Fourth Quarter						Year-to-Date
	Net Income (a)			Earnings per Share			Net Income (a)			Earnings per Share
2024 utility earnings	$	71		$	0.89		$	187		$	2.38
Changes in net income and diluted earnings per share:
Avista Utilities
Electric utility margin (including intracompany) (b)		20			0.24			88			1.09
Natural gas utility margin (including intracompany) (c)		4			0.05			18			0.22
Other operating expenses (d)		(10	)		(0.12	)		(48	)		(0.59	)
Depreciation and amortization (e)		(2	)		(0.03	)		(12	)		(0.15	)
Interest expense		(1	)		(0.01	)		(3	)		(0.04	)
Other (f)		(3	)		(0.04	)		(8	)		(0.10	)
Income tax at effective rate (g)		(6	)		(0.07	)		(13	)		(0.16	)
Dilution on earnings	n/a				(0.02	)	n/a				(0.07	)
Total Avista Utilities		2			(0.00	)		22			0.20
AEL&P		(1	)		(0.01	)		(2	)		(0.03	)
2025 utility earnings	$	72		$	0.88		$	207		$	2.55

The tax impact of each line item was calculated using Avista Corp.'s federal statutory tax rate of 21 percent.
Electric utility margin increased as a result of general rate cases, customer growth and non-decoupled load growth, partially offset by a $9 million pre-tax refund to be issued to customers for adjustments related to Colstrip investments. The Energy Recovery Mechanism (ERM) resulted in a $14 million pre-tax expense in 2025, compared to an $8 million pre-tax expense in 2024.
Natural gas utility margin increased primarily due to the effects of our general rate cases.
Other operating expenses increased due to increased employee salaries and benefits costs. In addition, net amortizations and deferrals associated with wildfire mitigation and insurance costs have increased, with corresponding increases to revenue which result in no impact to earnings.
Depreciation and amortization increased primarily due to additions to utility plant.
Other decreases to earnings include decreased interest income compared to the prior year and increased taxes other than income taxes.
Our effective tax rate in 2025 was 11% compared to 2% in the prior year. The change is primarily due to a decrease in tax customer credits as the majority of the tax customer credits have been returned to customers.

Analysis of 2025 Non-Regulated Other Business Losses

Losses at our non-regulated other businesses were $14 million in 2025, compared to $7 million in 2024. The fluctuation in results is primarily related to higher net investment losses. Approximately 75 percent of investment losses in 2025 were related to investments in clean technology. That sector was negatively impacted by shifting public policy and sentiment, leading to decreased valuations of underlying holdings in these investments. Approximately 25 percent of investment losses in 2025 were due to dilution of our ownership percentage in a biotechnology investment.

In 2025, we updated our estimates for an existing environmental remediation liability at one of our subsidiaries, which resulted in a pre-tax expense of $3 million.

Liquidity and Capital Resources

Liquidity

As of Dec. 31, 2025, we had $110 million of available liquidity under the Avista Corp. committed line of credit and $36 million of available liquidity under our letter of credit facility. AEL&P had $22 million available under their line of credit as of Dec. 31, 2025.

In July 2025, we issued $120 million of long-term debt, using proceeds to repay borrowings outstanding on our committed line of credit. Also in July 2025, AEL&P entered into a $20 million term loan, using the proceeds to repay borrowings under AEL&P's line of credit and fund capital expenditures.

We issued $78 million of common stock in 2025.

In 2026, we expect to issue approximately $230 million of long-term debt and up to $90 million of common stock.

Capital Expenditures

In 2025, Avista Utilities' capital expenditures were $553 million and AEL&P's capital expenditures were $17 million.

For Avista Utilities, we expect base capital expenditures as follows through 2030 (dollars in millions):

	2026		2027		2028		2029		2030
Expected base annual capital expenditures	$	585	$	635	$	800	$	680	$	710

These estimates include expenditures for the projects selected through our energy resource request for proposal. These estimates do not include incremental transmission projects, like regional grid expansion, or additional generation. We estimate hypothetical additional capital expenditures associated with integrating a new large load customer of up to $350 million, which is excluded from base capital above.

Capital expenditures at AEL&P are expected to be $17 million in 2026, $16 million in 2027 and $11 million in 2028.

2026 Utility Earnings Guidance and Outlook

Avista Corp. is initiating its 2026 non-GAAP utility earnings guidance with a range of $2.52 to $2.72 per diluted share.

This non-GAAP utility earnings guidance is based on the following assumptions:

Normal weather and hydroelectric generation
A negative impact from the ERM of ($0.10) cents per diluted share within the 90% customer, 10% company sharing band
An effective tax rate of 12 percent
Capital expenditures of $585 million
Effective regulatory outcomes

Over the long term, we expect non-GAAP utility earnings to grow 4 to 6 percent from the midpoint of our 2025 consolidated earnings guidance.

Our guidance does not include the effect of unusual or non-recurring items until the effects are probable. Various factors could cause actual results to differ materially from our expectations. Please refer to our 10-K for 2025 and the cautionary statements below for a full discussion of these factors.

Non-GAAP Financial Measures

This press release includes non-GAAP financial measures, including utility earnings, utility earnings per diluted share and utility margin. We present these non-GAAP measures in order to facilitate meaningful evaluation of our operating performance across periods, and we utilize these non-GAAP measures to assess current and forecast performance, as well as for communications with shareholders, analysts and investors. Non-GAAP measures are supplementary information that should be considered in addition to, but not as a substitute for, the information prepared in accordance with GAAP.

Non-GAAP utility earnings and utility earnings per diluted share exclude non-regulated other business activity, primarily consisting of realized and unrealized investment gains and losses. The presentation of utility earnings is intended to enhance the understanding of the Company's utility-specific operating performance.

The following table reconciles GAAP net income to non-GAAP utility earnings, and GAAP earnings per diluted share to non-GAAP utility earnings per diluted share for the fourth quarter and year ended Dec. 31, 2025 (dollars in millions, except per share amounts):

	Fourth Quarter				Year-to-Date
	2025		2024		2025		2024
GAAP net income as reported	$	71	$	67	$	193	$	180
Non-GAAP adjustments:
Non-regulated other business loss		1		4		14		7
Non-GAAP utility earnings	$	72	$	71	$	207	$	187

GAAP earnings per diluted share as reported	$	0.87	$	0.84	$	2.38	$	2.29
Non-GAAP adjustments:
Non-regulated other business loss per diluted share		0.01		0.05		0.17		0.09
Non-GAAP utility earnings per diluted share	$	0.88	$	0.89	$	2.55	$	2.38

The table below includes electric and natural gas utility margin. The most directly comparable measure calculated and presented in accordance with GAAP is utility operating revenues.

The presentation of electric and natural gas utility margin is intended to enhance the understanding of operating performance, as it provides useful information to investors in their analysis of how changes in loads (due to weather, economic or other conditions), rates, supply costs and other factors impact our results of operations.

The following table reconciles Avista Utilities' operating revenues to utility margin (after-tax) for the three and twelve months ended Dec. 31 (dollars in millions):

This news release contains forward-looking statements, including statements regarding our current expectations for future financial performance and cash flows, capital expenditures, financing plans, our current plans or objectives for future operations and other factors, which may affect the company in the future. Such statements are subject to a variety of risks, uncertainties and other factors, most of which are beyond our control and many of which could have significant impact on our operations, results of operations, financial condition or cash flows and could cause actual results to differ materially from those anticipated in such statements.

The following are among the important factors that could cause actual results to differ materially from the forward-looking statements:

Utility Regulatory Risk

state and federal regulatory decisions or related judicial decisions that affect our ability to recover costs and earn a reasonable return, including, but not limited to, disallowance or delay in the recovery of capital investments, operating costs, commodity costs, the ordering of refunds to customers and discretion over allowed return on investment; the loss of regulatory accounting treatment, which could require the write-off of regulatory assets and the loss of regulatory deferral and recovery mechanisms;

Operational Risk

weather conditions, which affect both energy demand and electric generating capability, including the impact of precipitation and temperature on hydroelectric resources, the impact of wind patterns on wind-generated power, weather-sensitive customer demand, and similar impacts on supply and demand in the wholesale energy markets; wildfires ignited, or allegedly ignited, by our equipment or facilities could cause significant loss of life and property or result in liability for resulting fire suppression costs and/or damages, thereby causing serious operational, reputational and financial harm; severe weather or natural disasters, including, but not limited to, avalanches, wind storms, wildfires, earthquakes, floods, extreme temperature events, snow and ice storms that could disrupt energy generation, transmission and distribution, as well as the availability and costs of fuel, materials, equipment, supplies and support services; political unrest and/or conflicts between foreign nation-states, which could disrupt the global, national and local economy, result in increases in operating and capital costs, impact energy commodity prices or our ability to access energy resources, create disruption in supply chains, disrupt, weaken or create volatility in capital markets, and increase cyber and physical security risks. In addition, any of these factors could negatively impact our liquidity and limit our access to capital, among other implications; explosions, fires, accidents, mechanical breakdowns or other incidents that could impair assets and may disrupt operations of our generation facilities, transmission, and electric and natural gas distribution systems or other operations and may require us to purchase replacement power or incur costs to repair our facilities; interruptions in the delivery of natural gas by our suppliers, including physical problems with pipelines themselves, can disrupt our service of natural gas to our customers and/or impair our ability to operate gas-fired electric generating facilities; explosions, fires, accidents or other incidents arising from or allegedly arising from our operations that could cause injuries to the public or property damage; dam failure at a company-owned hydroelectric facility; blackouts or disruptions of interconnected transmission systems (the regional power grid); terrorist attacks, cyberattacks or other malicious acts that could disrupt or cause damage to our utility assets or to the national or regional economy in general, including effects of terrorism, cyberattacks, ransomware, or vandalism that damage or disrupt information technology systems; pandemics, which could disrupt our business, as well as the global, national and local economy, resulting in a decline in customer demand, deterioration in the creditworthiness of our customers, increases in operating and capital costs, workforce shortages, losses or disruptions in our workforce due to vaccine mandates, delays in capital projects, disruption in supply chains, and disruption, weakness and volatility in capital markets. In addition, any of these factors could negatively impact our liquidity and limit our access to capital, among other implications; work-force issues, including changes in collective bargaining unit agreements, strikes, work stoppages, the loss of key executives, availability of workers in a variety of skill areas, and our ability to recruit and retain employees; changes in the availability and price of purchased power, fuel and natural gas, as well as transmission capacity; increasing costs of insurance, more restrictive coverage terms and our ability to obtain insurance; delays or changes in construction costs, and/or our ability to obtain required permits and materials for present or prospective facilities; increasing health care costs and cost of health insurance provided to our employees and retirees; increasing operating costs, including effects of inflationary pressures; third party construction of buildings, billboard signs, towers or other structures within our rights of way, or placement of fuel containers within close proximity to our transformers or other equipment, including overbuilding atop natural gas distribution lines; the loss of key suppliers for materials or services or other disruptions to the supply chain; adverse impacts to our Alaska electric utility (AEL&P) that could result from an extended outage of its hydroelectric generating resources or their inability to deliver energy, due to their lack of interconnectivity to other electrical grids and the availability or cost of replacement power (diesel); changing river or reservoir regulation or operations at hydroelectric facilities not owned by us, which could impact our hydroelectric facilities downstream;

Climate Change Risk

increasing frequency and intensity of severe weather or natural disasters resulting from climate change that could disrupt energy generation, transmission and distribution, as well as the availability and costs of fuel, materials, equipment, supplies and support services; change in the use, availability or abundancy of water resources and/or rights needed for operation of our hydroelectric facilities, including impacts resulting from climate change; changes in the long-term climate and weather could materially affect, among other things, customer demand, the volume and timing of streamflows required for hydroelectric generation, costs of generation, transmission and distribution.

¹ See reconciliations to GAAP measures and further information in the "Non-GAAP Financial Measures" section within this press release.

² Avista Corp. is unable to provide GAAP earnings guidance or present a quantitative reconciliation of forward-looking non-GAAP utility earnings and utility growth guidance without unreasonable effort because certain reconciling items are not estimable. For instance, realized and unrealized investment gains and losses, which have historically made up the majority of our non-regulated other business earnings and can be significant to our overall results, are difficult to predict due to various factors outside of management's control. These items are uncertain, depend on various factors, and may have a material impact on our future GAAP results.
