Power company profits

The California Public Utilities Commission proposed cutting the allowed return on equity by 0.35 percentage points for PG&E, Southern California Edison and San Diego Gas & Electric, taking their potential 2026 ROEs to 9.93%, 9.98% and 9.88% (from 10.28%, 10.33% and 10.23%). If approved in December, the move would push shareholder returns just under 10% for all three utilities — a modest hit to investor payouts that regulators argue could marginally curb bills but utilities warn will complicate financing and investment given rising rate bases and wildfire-mitigation costs. The commission left debt-equity ratios unchanged, keeping credit-rating considerations central to future financing dynamics for utility infrastructure and the state’s high retail power rates.

Analysis

Market structure: The 35bp ROE cut (PCG 10.28%→9.93%, EIX 10.33%→9.98%, SREA 10.23%→9.88%) is a direct headwind to utility equity cash returns but economically small — on the order of single-digit millions for each 0.35% move at company level (PG&E’s published sensitivity implies ~ $12.5m per 100bp → ~ $4–5m for 35bp). Consumers get marginal relief; incumbents keep monopoly pricing power so market share is unchanged, but earnings growth from rate-base expansion remains the dominant driver. Cross-asset: expect equity vols to tick up around the CPUC December vote, modest widening in subordinated utility credit spreads if equity ratios/credit metrics are later adjusted, and negligible immediate commodity/FX impact.

Risk assessment: Tail risks include a larger-than-expected ROE cut (>100bp), CPUC-mandated equity/debt ratio shifts, or regulatory disallowance of wildfire costs — any of which could trigger rating downgrades and 5–15% equity drawdowns. Timeline: immediate (days) — IV repricing and short-term selloffs; short-term (weeks to 3 months) — outcome of CPUC vote in December; long-term (12–36 months) — capex pacing, credit rating changes and rate-base growth trajectory. Hidden dependency: utilities rely on allowed ROE + regulatory capital structure to maintain investment-grade metrics; the commission left debt/equity unchanged — that’s the lever to watch.

Trade implications: Favor selective short/hedge positions into the December vote: PCG shows the worst sentiment hit and structural wildfire/legal risk, EIX the second, SREA least impacted. Use options to limit capital: buy ~90–150 day puts straddling the vote, or enter pair trades (short PCG vs long SREA) to isolate regulatory beta. Rotate proceeds into non-California regulated growth in clean energy developers/owners if capex from IOUs slows.

Contrarian angles: The cut is small and may be largely priced in; markets that sell first and analyze later create arbitrage: if the vote passes with no debt/equity changes and ratings remain stable, PCG/EIX could rebound 5–10% as fears abate. Historical parallels (state ROE compressions in the 2000s) show muted long-term equity damage when rate-base growth continues. Unintended consequence: utilities may increase leverage to offset ROE pressure, raising future credit risk — that’s the real latent cost to ratepayers and bondholders.

Key Decisions for Investors

• Establish a targeted short position in PCG (size 1–2% portfolio) via borrowed stock or synthetic short; enter now and trim/close within 2–6 weeks after the CPUC vote in December if no additional equity/debt action is announced. Use a stop-loss of 8% above entry to limit blow-ups.
• Initiate a relative-value pair trade: short PCG (notional X) / long SREA (notional X) for 1–3% portfolio exposure, horizon 3–6 months to capture regulatory re-pricing while neutralizing macro rates and sector moves.
• Buy 120-day PCG puts ~5% OTM (size 0.5% portfolio) that expire after the December CPUC vote to hedge event risk; replicate a smaller position in EIX (0.25% portfolio) if implied vol < historical 30‑day realized vol to keep theta affordable.
• Rotate 1–2% into NextEra Energy (NEE) and Bloom Energy (BE) as beneficiaries if IOU capex growth slows; hold 12–24 months to capture re-rating into non-CA clean-energy growth streams.
• Trigger rule: if S&P or Moody’s places PCG or EIX on negative watch within 30 days post-vote, increase short exposure to PCG/EIX by +1% each and add credit protection (buy CDS or long-term bond puts) to defend against a rating-driven selloff.
