IDACORP (IDA) Q1 2026 earnings review
Rate Hikes Deliver Strong Q1 Amid Massive CapEx Acceleration
IDACORP delivered a robust Q1 with EPS up 10% YoY to $1.21. The new January 1 base rates proved highly effective, boosting operating income by $18.0M and allowing the company to absorb a massive $13.1M O&M cost spike. Furthermore, the Fixed Cost Adjustment (FCA) mechanism worked flawlessly, contributing $19.1M to entirely offset a $10.7M usage drag caused by mild winter weather. Most importantly, earnings quality improved: the company relied on just $6.3M in tax credits versus $19.3M a year ago. Management reaffirmed FY26 EPS guidance of $6.25-$6.45, backed by stable 2.3% customer growth and the execution of an unprecedented $7B, five-year CapEx cycle.
🐂 Bull Case
The FCA mechanism contributed $19.1M in Q1, successfully shielding earnings from a $10.7M usage decline due to a mild winter. This decoupling drastically reduces near-term revenue risk from macro weather events.
ADITC tax credit usage dropped by 67% YoY ($6.3M vs $19.3M). The company is generating strong enough cash flow from new base rates to hit targets without draining its regulatory reserves.
🐻 Bear Case
O&M expenses spiked $13.1M YoY due to wildfire mitigation and Jim Bridger conversion costs. If expense growth consistently outpaces base rate relief, margins will compress outside of test years.
Management trimmed the top end of its FY26 hydro generation forecast by 500,000 MWh due to poor precipitation. Lower hydro output historically forces reliance on more expensive purchased power, pressuring margins.
⚖️ Verdict: 🟢
Bullish. IDACORP is successfully managing unprecedented load growth while improving earnings quality. The ability to post double-digit EPS growth, absorb heavy O&M inflation, and drastically cut tax credit usage proves their regulatory strategy is working.
Key Themes
Rate Case Secures the Bottom Line
The Idaho general rate case settlement (effective Jan 1) was the undisputed engine of Q1 growth, contributing $18.0M to operating income. This injection was critical—it allowed IDACORP to fully absorb a $13.1M surge in O&M costs without missing a beat. The rate relief fundamentally improved earnings quality, allowing the company to reduce its reliance on ADITC tax credits.
O&M Inflation Eats Rate Gains
While the rate increase was a victory, the underlying cost structure is deteriorating. O&M expenses jumped $13.1M YoY, driven by the expanding wildfire mitigation program and amortization of the Jim Bridger coal-to-gas conversion. This single line item erased 72% of the $18.0M base rate gain. If inflation persists, regulatory lag will become a severe headwind.
Hydropower Degradation Threatens Power Costs
Management quietly trimmed the top end of its FY26 hydropower generation guidance from 7.5M to 7.0M MWh, citing lower Q1 precipitation. This contradicts the rosy narrative of a smooth operational year. Because hydro is Idaho Power's cheapest baseload, any shortfall forces the company into higher-cost thermal generation or market purchases, which could squeeze margins in H2.
FCA Mechanism Eliminates Macro Weather Risk
Mild winter temperatures drove a $10.7M decline in retail usage—a macro event that typically crushes utility earnings. However, IDACORP's Fixed Cost Adjustment (FCA) mechanism operated flawlessly, injecting $19.1M into revenues to offset the volume loss. This proves the company has successfully decoupled a massive portion of its revenues from macro weather volatility.
Unprecedented CapEx Cycle Introduces Execution Risk
IDACORP is embarking on a 5-year, $7B CapEx super-cycle to support an 8.3% forecasted retail sales growth driven by large data centers. The 2026-2030 average annual spend of $1.41B is double the prior 5-year average of $709M. Navigating supply chain constraints, tariffs, and permitting for mega-projects like the Boardman-to-Hemingway transmission line leaves zero room for error.
Rapid Deployment of Dispatchable Tech
To ensure grid stability alongside massive intermittent load additions, IDACORP is aggressively scaling battery storage technology. The company is actively deploying a 250 MW Battery Energy Storage System (BESS) expansion at Bennett in 2026, with an additional 167 MW at South Hills and 222 MW at Peregrine slated by 2030. This specific tech pivot is essential for peak-shaving and integrating renewable assets.
Other KPIs
Decelerating significantly from $19.3M a year ago. This is a crucial indicator of earnings quality. Management relies on these tax credits to prop up earnings when regulatory lag hurts returns. Needing only $6.3M in Q1 leaves a healthy buffer against the <$30M annual guidance and proves the new base rates are doing the heavy lifting.
Accelerating. The higher expense was driven by increased interest from long-term debt balances to fund the massive CapEx program, as well as a new finance lease. This line item will remain a structural headwind as debt scales toward the $2.2B needed by 2030.
Guidance
Stable. Management reaffirmed guidance, implying a solid 7.6% YoY growth at the midpoint. This assumes normal weather and power supply expenses for the rest of the year.
Stable. Unchanged from prior expectations, but represents a massive acceleration versus historical norms. This marks the beginning of the aggressive 5-year cycle intended to essentially double the rate base by 2030.
Decelerating. Management clipped the top end of the range (previously 7.5 million MWh) due to lower precipitation in Q1. Because hydro is Idaho Power's cheapest energy source, lower output increases the risk of margin compression later in the year.
Stable. Reaffirmed guidance range. However, the $13.1M spike in Q1 alone suggests the company is currently tracking toward the higher end of this range, driven by structural increases in wildfire mitigation costs.
Key Questions
Hydro Degradation Impact
With the top end of the hydro forecast lowered by 500,000 MWh, how much upward pressure does this put on H2 power supply costs, and could it force you to utilize more than the guided $30M in ADITC?
O&M Run-Rate
O&M expenses jumped $13.1M in Q1. What percentage of this increase is structural run-rate versus one-time timing, and are you now tracking toward the absolute top end of the $525-$535M annual guidance?
Equity Issuance Timeline
Given the massive $1.4B/year CapEx plan, what is the exact timeline and strategy for future equity issuances once the current forward sale agreements are completely exhausted?
