IDACORP's High-Stakes Growth Gamble Ahead of Q4 2025 Earnings

BOISE, ID – February 05, 2026 – As IDACORP, Inc. (NYSE:IDA) prepares to release its fourth-quarter and full-year 2025 financial results on February 19, investors and regional stakeholders are watching with keen interest. The announcement is more than a routine financial disclosure; it represents a critical checkpoint for a company navigating a period of unprecedented growth, massive capital investment, and a complex regulatory environment in the rapidly expanding Pacific Northwest.

Following a strong third quarter that saw the company raise its full-year earnings guidance, expectations are high. However, the numbers themselves may be secondary to the forward-looking commentary from leadership. With a recently approved rate hike for Idaho customers and a long-term plan forecasting energy demand growth of nearly 45%, the upcoming analyst call will be scrutinized for details on how the utility plans to fund its future while balancing affordability for its more than 660,000 customers.

A Strong Financial Foundation Sets High Expectations

IDACORP enters this reporting period from a position of financial strength. In its third-quarter 2025 report, the company posted a net income of $124.4 million, or $2.26 per diluted share, slightly beating analyst estimates. This robust performance, driven by continued customer growth and approved rate changes, prompted the company to increase its full-year 2025 earnings guidance to a range of $5.80 to $5.90 per share.

This follows a pattern of solid results, including a strong full-year 2024 where earnings per share grew to $5.50 from $5.14 in the prior year. The company's stock has reflected this positive momentum, appreciating over 21% in the last twelve months. Wall Street sentiment remains largely positive, with a "Moderate Buy" consensus rating from analysts who see potential in the utility's stable, regulated business model situated in one of the nation's fastest-growing regions. Investors will be listening intently on February 19 for confirmation that the company has met its upwardly revised 2025 targets, which would set a powerful precedent for the ambitious years ahead.

The IRP: A Blueprint for an Energy-Hungry Future

The central challenge and opportunity for IDACORP is encapsulated in its 2025 Integrated Resource Plan (IRP). Filed last summer, the 20-year roadmap paints a picture of staggering growth. The utility's primary subsidiary, Idaho Power, projects that peak energy demand will surge by nearly 1,700 megawatts (MW) by 2045—a nearly 45% increase. Most strikingly, almost 1,000 MW of that growth is expected within the next five years alone, an increase in capacity nearly 50% larger than the company's single largest asset, the Brownlee hydropower plant.

This demand is fueled by a booming population and significant commercial expansion, including the major expansion of semiconductor manufacturer Micron in Boise. To meet this need, IDACORP has outlined a substantial capital investment strategy, with planned expenditures between $1 billion and $1.1 billion for 2025 and elevated spending expected for several years to come. The IRP calls for a multi-pronged approach that includes expanding generation resources, investing heavily in battery storage, bolstering energy efficiency programs, and building critical high-voltage transmission lines like the Boardman-to-Hemingway and Southwest Intertie projects. The upcoming earnings call will be a key opportunity for management to provide updates on the progress and financing of these capital-intensive projects.

Navigating the Regulatory and Customer Impact

Executing this growth plan requires navigating a delicate regulatory path. In a significant development, the Idaho Public Utilities Commission (IPUC) recently approved a settlement that resulted in an overall average rate increase of 7.48% for Idaho Power customers, effective January 1, 2026. The utility argued the increase was necessary to recover costs associated with infrastructure investments, addressing the 2.6% year-over-year customer growth, and funding critical wildfire mitigation efforts, estimated at around $25 million.

While the approved increase was less than some initial proposals, it underscores the direct impact of the company's expansion on its customers. This balancing act was further highlighted by another recent IPUC decision. In November 2025, the commission rejected an appeal to reconsider its ruling that allowed Idaho Power to decrease the export credit rates paid to new rooftop solar customers by 31%. The decision, which impacts thousands of households, was a win for the utility's cost-of-service argument but a significant blow to the local solar industry and customers who invested in solar technology. These regulatory outcomes demonstrate the tightrope IDACORP must walk between investing for growth and maintaining its long-held reputation for providing some of the nation's lowest electricity prices.

Hydropower's Role in a Cleaner, Larger Grid

At the core of Idaho Power's identity and value proposition are its 17 low-cost hydropower projects, a legacy that has historically provided clean and affordable energy. This hydropower advantage remains central to the company's long-term strategy to provide 100% clean energy by 2045. The investments outlined in the IRP are not just about adding capacity but also about modernizing the grid to integrate new technologies while maintaining reliability.

As the company invests in battery storage to firm up intermittent renewables and new transmission to access diverse energy markets, its foundational hydropower assets provide a crucial source of stability. The upcoming earnings report will likely reinforce this strategy, framing the massive capital expenditures not merely as a response to growth but as a necessary step toward building a larger, more resilient, and ultimately cleaner grid for the future. The focus for analysts and investors will be how the company manages the immense costs and operational challenges of this transition while delivering consistent returns.
