Pinnacle West Earnings Call Highlights Growth Momentum

Pinnacle West Capital ((PNW)) has held its Q1 earnings call. Read on for the main highlights of the call.

Pinnacle West Capital’s latest earnings call struck an optimistic tone as management highlighted a sharp earnings rebound, robust underlying demand, and solid execution on major grid and generation projects. While higher financing costs, regulatory uncertainty, and large future capital needs remain in focus, management argued that strong top-line growth and successful funding actions leave the company on firmer footing.

Earnings Recovery Signals Financial Turnaround

Pinnacle West reported Q1 2026 EPS of $0.27, a $0.31 swing from the $0.04 loss a year ago, marking a clear earnings recovery. Management attributed the improvement to higher transmission revenue, favorable weather, strong sales and usage trends, and lower O&M expenses, partially offsetting cost pressures elsewhere.

Transmission Revenues Drive Material EPS Upside

Transmission investments are starting to pay off, adding $0.16 per share to Q1 results and tracking closely with full‑year guidance. The stepped‑up build‑out of transmission infrastructure is becoming a core earnings engine, supporting both reliability and financial performance as load continues to grow across the service territory.

Sales Momentum and Customer Growth Remain Strong

Weather‑normalized sales surged 9.4% in the quarter, with commercial and industrial usage up 14.6% and residential up 1.8%, underscoring broad‑based demand. Customer growth came in at 2.2%, near the high end of management’s annual guidance range, signaling ongoing population and economic strength in the company’s Arizona footprint.

Record Heat Provides a Weather Tailwind

Weather was a notable earnings booster as a very hot March, including nine days at or above 100°F, lifted cooling demand across residential and commercial customers. Management estimated that favorable weather added about $0.13 per share in Q1, amplifying the underlying demand growth and supporting the strong year‑over‑year comparison.

Large‑Load Pipeline Offers Long‑Term Upside

The company highlighted roughly 4.5 GW of committed extra‑high‑load customers alongside an elevated 20 GW uncommitted queue, pointing to a substantial long‑term growth runway. While not all queued projects will materialize, the scale of potential large‑load additions positions Pinnacle West for significant future contracted load growth and associated resource needs.

Progress on Generation and Transmission Build‑Out

Construction is underway on the Red Hawk expansion, which will add eight combustion turbines totaling around 400 MW of new natural‑gas capacity aimed at meeting rising peak demand. The Desert Sun project is also advancing with key equipment reserved and siting and permitting moving forward, while the return of Palo Verde Unit 2 should have all three nuclear units online for summer reliability.

Customer Satisfaction and Program Awareness Stay High

Management emphasized strong customer‑facing metrics, noting APS ranks in the first or second quartile across Escalent core KPIs and in the first quartile with J.D. Power. The utility also achieved the highest national awareness score for its customer programs, suggesting effective outreach and engagement as it navigates rapid growth and infrastructure investment.

Capital Plan and Equity Funding De‑Risked

All equity needs for 2026 are already funded, with nearly $850 million of priced equity in hand, including more than $350 million raised in Q1 alone. Management stressed that its multi‑year equity plan is largely de‑risked and supported by a balanced debt‑equity strategy and ongoing constructive dialogue with rating agencies, which have maintained stable credit outlooks.

Financing Costs Curb Some of the Upside

Despite strong operating trends, higher interest expense weighed on results as recent debt issuances increased overall borrowing costs. Management acknowledged that elevated rates are a headwind to net earnings and cash flow, reinforcing the importance of disciplined capital allocation and regulatory outcomes to support the balance sheet.

Lower Contribution from Portfolio Investment

The company’s Eldorado investment delivered a smaller benefit than in the prior‑year quarter, modestly dragging year‑over‑year earnings. While not a primary earnings driver, this reduced contribution underscores that some historical tailwinds are fading even as core utility operations strengthen.

Depreciation Rises with Growing Asset Base

Depreciation and amortization expense moved higher as new plants and infrastructure were placed into service, partially offset by the retirement of the Cholla facility. The higher non‑cash expense reflects the capital‑intensive nature of Pinnacle West’s growth strategy and adds pressure to reported earnings even as assets begin contributing to reliability and capacity.

Regulatory Lag and Rate Case Outcomes in Focus

A pending rate case, with hearings beginning in mid‑May, remains a key swing factor for returns and cash flow timing. Management is targeting a 50‑basis‑point reduction in the ROE gap and a narrowing of structural regulatory lag by 2029, but acknowledged that outcome uncertainty and lag continue to influence earnings visibility and investment pacing.

Converting the Massive Queue into Firm Load

The nearly 20 GW uncommitted queue offers tantalizing growth potential but comes with significant execution risk, including duplicative projects and complex subscription‑model negotiations. Management stressed that actual conversion will depend on regulatory approvals and infrastructure build‑outs, leaving timing and ultimate subscription rates uncertain despite the attractive headline number.

Ongoing CapEx Needs and Future Issuance Plans

Beyond the fully funded 2026 plan, Pinnacle West still expects about $1.0–$1.2 billion of new‑money equity needs from 2026 through 2028, with 2026 representing roughly $650 million of that base case. Future equity and debt issuance will be opportunistic and influenced by rate‑case results, cash‑flow realization, and the pace at which large‑load opportunities firm up.

Higher Costs for New Gas Capacity

Management flagged a higher‑cost environment for new gas generation, driven by supply‑chain pressures and general inflation in equipment and construction. While conversions and additions can still be competitive in the resource mix, the rising capital intensity could affect project economics and scheduling, adding another layer of complexity to planning the future fleet.

Guidance and Long‑Term Growth Outlook Reaffirmed

The company reaffirmed 2026 financial and financing guidance alongside Q1 EPS of $0.27, underscoring confidence in full‑year performance despite volatile weather. Sales guidance remains 4%–6% annually, with a 5%–7% long‑term growth target through 2030, while management expects transmission to remain a key earnings contributor and continues to prepare an updated resource plan this summer.

Pinnacle West’s call painted a picture of a utility leaning into growth, with strong demand, a deep large‑load pipeline, and major projects moving forward, all underpinned by de‑risked near‑term funding. Investors will now focus on the upcoming rate case and execution on the 20 GW queue, but for now the balance of higher earnings visibility and manageable headwinds appears to favor a constructive outlook.
