IDACORP, Inc. Announces First Quarter 2025 Results, Reaffirms 2025 Earnings Guidance

BOISE, Idaho--IDACORP, Inc. (NYSE: IDA) reported first quarter 2025 net income attributable to IDACORP of $59.6 million, or $1.10 per diluted share, compared with $48.2 million, or $0.95 per diluted share, in the first quarter of 2024.

“IDACORP's earnings benefited from continued strong customer growth, rate changes, and the expected use of tax credits under the company’s Idaho regulatory mechanism,” said IDACORP President and Chief Executive Officer Lisa Grow. "Consistent with recent quarters, higher depreciation and financing costs partially offset those benefits, as we continue to acquire resources and build infrastructure to respond to rapidly growing customer needs."

“We remain focused on executing on our capital investment and regulatory plan to support ongoing growth and energy reliability and resiliency for all of our customers. It is an exciting year, with the company preparing to start construction on its three major transmission projects and continue to work through the resource procurement process for generation resources,” Grow added.

IDACORP reaffirms 2025 earnings guidance in the range of $5.65 to $5.85 per diluted share with the expectation that Idaho Power will use between $60 million and $77 million of additional tax credits available under the Idaho regulatory mechanism in 2025. The earnings guidance also assumes normal weather conditions and power supply expenses through the end of 2025.

Summary of Financial Results

The following is a summary of net income attributable to IDACORP and IDACORP's earnings per diluted share for the three months ended March 31, 2025 and 2024 (in thousands, except earnings per share amounts):

Three months ended <br>March 31,
2025 2024
Net income attributable to IDACORP, Inc. $ 59,647 $ 48,173
Weighted average outstanding shares – diluted 54,126 50,792
IDACORP, Inc. earnings per diluted share $ 1.10 $ 0.95

The table below provides a reconciliation of net income attributable to IDACORP for the three months ended March 31, 2025, from the same period in 2024 (items are in millions and are before related income tax impact unless otherwise noted):

Three months ended
Net income attributable to IDACORP, Inc. - March 31, 2024 $ 48.2
Increase (decrease) in Idaho Power net income:
Retail revenues per megawatt-hour (MWh), net of power cost adjustment mechanisms 11.3
Customer growth, net of associated power supply costs and power cost adjustment mechanisms 7.3
Usage per retail customer, net of associated power supply costs and power cost adjustment and fixed cost adjustment (FCA) mechanisms (2.1)
Other operations and maintenance (O&M) expenses (7.2)
Depreciation expense (5.8)
Other changes in operating revenues and expenses, net 1.9
Increase in Idaho Power operating income 5.4
Non-operating expense, net (2.2)
Additional accumulated deferred investment tax credits (ADITC) amortization 6.8
Income tax expense, excluding additional ADITC amortization 0.8
Total increase in Idaho Power net income 10.8
Other IDACORP changes (net of tax) 0.6
Net income attributable to IDACORP, Inc. - March 31, 2025 $ 59.6

IDACORP's net income increased $11.4 million for the first quarter of 2025 compared with the first quarter of 2024, due primarily to higher net income at Idaho Power.

A net increase in retail revenues per MWh, net of power cost adjustment mechanisms, increased operating income by $11.3 million in the first quarter of 2025 compared with the first quarter of 2024. This benefit was due primarily to an overall increase in Idaho base rates, effective January 1, 2025, per the limited-issue rate case Idaho Power filed with the Idaho Public Utilities Commission (IPUC) finalized by order of the IPUC in December 2024.

At Idaho Power, customer growth increased operating income by $7.3 million in the first quarter of 2025 compared with the first quarter of 2024, as the number of Idaho Power customers grew by approximately 16,500, or 2.6 percent, during the twelve months ended March 31, 2025. Usage per retail customer was relatively consistent in the first quarter of 2025 compared with the first quarter of 2024. Residential usage per customer increased, as lower temperatures in the first quarter of 2025 compared with the first quarter of 2024 led residential customers to use more energy for heating purposes, but the increase was offset by a slight decrease in industrial usage per customer and the effects of customer mix changes. An increase in the deferral of residential and small commercial customer revenues through the FCA mechanism negatively affected retail revenues by $1.5 million.

Other O&M expenses in the first quarter of 2025 were $7.2 million higher than the first quarter of 2024, partially related to an approximate $3.2 million increase in wildfire mitigation program and related insurance expenses. In addition, other O&M expenses increased $1.8 million due to a decrease in grant funding received for maintenance work in the first quarter of 2025 as compared to the first quarter of 2024. Inflationary pressures on labor-related costs also contributed to the increase in other O&M expenses.

Depreciation expense increased $5.8 million in the first quarter of 2025 compared with the first quarter of 2024, due primarily to an increase in plant-in-service.

Other changes in operating revenues and expenses, net, increased operating income by $1.9 million in the first quarter of 2025 compared with the first quarter of 2024, due primarily to a decrease in net power supply expenses that were not deferred for future recovery in rates through Idaho Power's power cost adjustment mechanism, which increased other changes in operating revenues and expenses, net, compared with the

same period in 2024. More moderate and less volatile wholesale natural gas and power market prices in the western United States decreased Idaho Power's net power supply expenses in the first quarter of 2025 compared with the first quarter of 2024.

Non-operating expense, net, increased $2.2 million in the first quarter of 2025 compared with the first quarter of 2024. Higher long-term debt balances and an increase in transmission customer deposits, on which Idaho Power must pay interest to the customer, led to an increase in interest expense. This increase was partially offset by an increase in allowance for funds used during construction (AFUDC) in the first quarter of 2025 compared with the first quarter of 2024, as the average construction work in progress balance was higher.

The decrease in income tax expense was principally the result of an increase in additional ADITC amortization. Based on Idaho Power's current expectations of full-year 2025 financial results, Idaho Power recorded $19.3 million of additional ADITC amortization under its Idaho regulatory settlement stipulation during the first quarter of 2025, compared with $12.5 million of additional ADITC amortization during the same period in 2024.

If the net balances of Idaho Power’s capital additions and retirements since the Idaho limited scope rate case and its forecasted capital additions and retirements were approved by its regulators to be included in base rates, Idaho Power’s total system rate base could reach approximately $9.7 billion by the end of 2029, the year through which Idaho Power currently forecasts capital expenditures. Idaho Power’s 2024 Idaho limited scope rate case provided for a return on a rate base of about $4.4 billion (system total), which excludes net rate base on coal-related assets related to North Valmy and Jim Bridger plants of approximately $0.2 billion which are included through regulatory mechanisms. The 2024 rate base amounts are adjusted in this graphic over time to reflect the ultimate decline in net rate base of coal-related assets. Coal-related rate base is expected to be fully collected by the end of 2028 and 2030, respectively, through separate regulatory orders. (2) Hells Canyon Complex (HCC) relicensing costs becoming eligible for rate base is subject to the Federal Energy Regulatory Commission’s granting of a new operating license. Estimated to be approximately $0.4 billion of rate base for illustration purposes. As of February 20, 2025, Idaho Power believed that the HCC license would be issued as early as 2026; however, as of May 1, 2025, Idaho Power believes that the license won’t be issued until 2027 or later. 16.1% CAGR 2025-2029 ~$5.1B 13
