Pinnacle West (PNW) Q3 2026 Earnings Call Transcript

Pinnacle West reported Q3 diluted EPS of $3.49, up $0.10 year over year, and raised 2026 EPS guidance by $0.50 at both ends to $5.05–$5.25. Weather-normalized retail sales grew 9.5%, and the company lifted its 2026 and through-2030 sales growth outlooks to 8%–10%; its 25-year TSMC contract is for 1.88 GW of demand at full build-out, subject to regulatory approval. Management identified nearly 15 GW of new resources and 2.6 GW of transmission capacity in its plan through 2041, while noting higher interest and depreciation expenses and a pending rate-case decision expected before year-end.

Analysis

The useful distinction is between load growth and shareholder earnings growth. PNW’s upside depends on converting incremental demand into prudently approved rate base without financing dilution and regulatory lag consuming the returns. Customer-funded infrastructure under the direct-pricing framework may improve that conversion, but the actual cash protections, cost allocation, and Commission treatment matter more than management’s “growth pays for growth” framing. Transmission and system reliability spend can still have broader rate-base beneficiaries and cost-allocation disputes.

Near term, the year-end rate decision is the cleanest catalyst; a constructive order would reduce uncertainty, not instantly eliminate lag. Formula-rate recovery beginning in 2027, with management describing 2029 as the first full run-rate year, makes the earnings payoff a months-to-years story. Higher depreciation and interest costs, plus equity issuance, are the counterweight. Long-term sales estimates also deserve a haircut until projects move from evaluation or announcement to executed, credit-supported commitments. In particular, announced expansion plans by AMKR and KMB should not be treated as contracted PNW load; TSM demand is more concrete but remains subject to regulatory approval.

Contrarian angle: the market may capitalize load forecasts too quickly, while underweighting how much capital and time it takes to turn them into per-share returns. Conversely, treating PNW as a conventional slow-growth utility may miss the value of customer-backed investment if rate recovery works. Falsifiers include an adverse rate-case decision, weaker committed-load conversion, delayed resource approvals, or further financing needs that outpace cash recovery.

Key Decisions for Investors

• Keep PNW on a catalyst-driven long watch rather than chasing the guidance reset. Consider a staged long versus XLU only after reviewing the final rate order and updated capital plan; the thesis is stronger if approved recovery and customer contributions support per-share earnings, not merely asset growth.
• Before adding, verify the rate-case allowed return and implementation terms, the filed TSM contract’s Commission treatment, and the size/timing of DPC cash support. These details determine whether load growth offsets financing and regulatory-lag costs.
• Treat AMKR and KMB Arizona expansions as conditional demand optionality, not near-term PNW catalysts. Reassess only if PNW identifies signed service commitments or customer-backed infrastructure for those projects.
• Trim or invalidate the growth thesis if the rate order fails to narrow recovery lag, committed demand slips, or equity/debt funding rises without a corresponding improvement in cash recovery and per-share guidance.
