IDACORP’s Q1 2026 Earnings: Batteries, Guidance, and a Steady Grid for Growth

Executive snapshot

IDACORP, Inc. reported first-quarter 2026 net income of about $68.0 million, or $1.21 per diluted share, up from $59.6 million, or $1.10 per diluted share, in Q1 2025. The company also reaffirmed its full-year 2026 earnings guidance in the range of $6.25 to $6.45 per diluted share. Management notes that Idaho Power will likely deploy less than $30 million of additional tax credits under the regulatory mechanism in 2026, a detail that matters for margins and the “revenue forecast” embedded in guidance.

The press release highlights growth in customer base and rate changes as the engine behind the quarterly improvement, while acknowledging higher operations and maintenance costs and the drag of fewer tax credits under Idaho’s regulatory framework. The quarter’s topline metrics demonstrate a disciplined path through a period of deliberate investment in grid modernization and storage.

Key numbers in plain English

• Net income attributable to IDACORP: $67.98 million for three months ended March 31, 2026.
• EPS (diluted): $1.21 for the quarter, up from $1.10 in the prior-year period.
• Weighted average diluted shares: roughly 56.3 million in 2026 vs. ~54.13 million in 2025.
• Guidance: 2026 earnings per diluted share of $6.25–$6.45.
• Regulatory credits: Idaho Power is expected to use under $30 million of additional credits in 2026 under the Idaho mechanism.

In the narrative, the company emphasizes that the result benefited from customer growth and rate changes, while O&M costs rose and a reduction in tax credits weighed on the bottom line. The numbers align with a strategy of upgrading the grid—specifically, adding up to 250 MW of batteries and continuing major transmission and generation projects.

Management commentary and strategic focus

CEO Lisa Grow framed the quarter as part of a broader growth trajectory: a period of execution with reliability and affordability front and center for customers and a focus on driving shareholder value. The battery deployment cadence—250 MW coming online—signals a shift toward storage as a backbone of Idaho Power’s reliability and price stability, a move that could inform peers eyeing similar grids-scale investments.

The narrative also underscores prudent cost management. While O&M expense rose, the company remains deliberate about tax credits and regulatory mechanics that affect earnings. The reaffirmed 2026 EPS guidance suggests confidence in the trajectory, contingent on weather, power supply costs, and the regulatory framework holding steady.

Implications for the sector and peers

IDACORP’s quarter offers a window into how regulated utilities balance growth investments with rate-case economics. The emphasis on 250 MW of batteries hints at a broader industry push toward storage as a hedge against price volatility and a means to smooth demand. If IDACORP’s approach proves durable, peers may accelerate grid modernization opt-ints, potentially pressuring other utilities to revisit capital plans and rate mechanisms.

The Idaho regulatory mechanism and its treatment of tax credits will remain a key variable for earnings visibility across the sector. A disciplined approach to credits—utilized versus carried forward—can meaningfully alter the earnings trajectory and the apparent EPS consensus versus the company’s own revenue forecast.

What this means for investors

For stock reckonings, IDA’s results imply a reasonable expectational path: continued growth in customer base, steady earnings growth tied to regulated rates, and a disciplined capital program in storage and transmission. An earnings surprise would hinge on how close the quarter lands to analysts’ EPS consensus and how the revenue forecast embedded in the guidance is interpreted against weather risk and O&M dynamics.

In the near term, market participants will watch how IDA sustains its glide path to the mid-point of its guidance range, and whether the battery program accelerates beyond the 250 MW mark. Any shift in regulatory treatment of tax credits or a sharper-than-expected rise in O&M could nudge the stock’s multiple, especially as peers digest similar capital plans.

Bottom line and outlook

IDACORP’s Q1 2026 release reads like a roadmap rather than a one-off favor: a company leaning into grid modernization, leveraging rate-driven growth, and maintaining a clear earnings trajectory in a regulated environment. The battery push and the reaffirmed guidance imply that the company expects to translate capital intensity into predictable cash flow, even as it navigates regulatory credits and weather-related variability.

If the sector follows IDACORP’s lead, we may see more utilities lining up capital-intensive projects with a clearer tax-credits playbook and a stronger emphasis on storage as a pricing anchor. In other words, the grid isn’t just getting bigger; it’s getting smarter—and a touch more credit-friendly for investors who prize durability over drama.
