Dividend Stability: A Track Record of Resilience

Edison International has demonstrated remarkable consistency in its dividend payments. For 2025, the company declared a quarterly dividend of $0.8275 per share, translating to an annualized payout of $3.31 and a yield of 5.95% as of July 2025Edison International (EIX) Dividend History, Dates & Yield^[2]. This yield significantly outpaces the 4.11% rate of the 10-year Treasury bond as of September 19, 2025US Treasury Rates: Bond & Bill Yields with Duration Analysis^[6], offering investors a premium of 1.84 percentage points. Such a spread is rare in high-rate environments, where utility stocks often trade at a discount to Treasuries due to perceived interest rate sensitivity.

The company's ability to sustain and grow dividends is underpinned by its regulated business model. Southern California Edison (SCE), its primary operating subsidiary, operates under a cost-of-service framework, allowing it to pass through inflationary pressures to customers via rate adjustments. For instance, in Q2 2025, Edison reaffirmed its core earnings guidance of $5.94–$6.34 per share despite a 10.27% year-over-year increase in the 10-year Treasury rateEdison International Reports Second-Quarter 2025 Results^[1]. This resilience stems from SCE's ability to secure regulatory approvals for revenue adjustments, including a 2025 Return on Equity (ROE) adjustment that mitigated earnings volatilityEdison International Reports Second-Quarter 2025 Results^[1].

Defensive Qualities in High-Rate Environments

While utilities are traditionally viewed as interest rate-sensitive, Edison's structural advantages reduce this risk. The company's capital-intensive operations require significant borrowing, yet Q1 2025 interest expenses fell 32.2% year-over-year to $301 million, reflecting lower borrowing costs in the utility sectorEdison International Reports Second-Quarter 2025 Results^[1]. This trend aligns with broader industry dynamics: as the Federal Reserve pauses rate hikes, utilities benefit from reduced debt servicing costs, enhancing free cash flow and dividend sustainability.

Moreover, Edison's dividend yield of 4.33% as of late 2025Edison International (EIX) Dividend Yield 2025, Date & History^[4] compares favorably to the 4.08% 10-year Treasury rate on September 9, 2025Edison International Reports Second-Quarter 2025 Results^[1]. This premium is particularly attractive in a high-rate environment, where investors demand higher yields to compensate for inflation. Edison's yield also outperforms the S&P 500's average dividend yield of ~1.5%, underscoring its role as a bond proxyUS sectors to watch as Fed lines up first rate cut of 2025^[5].

Risk Mitigation and Long-Term Growth

Edison's defensive appeal is further bolstered by its long-term growth trajectory. The company projects a 5–7% compound annual growth rate (CAGR) in core earnings per share through 2028Edison International Reports Second-Quarter 2025 Results^[1], driven by infrastructure investments and regulatory tailwinds.

Such proactive risk management enhances earnings predictability, a critical factor for dividend sustainability.

However, investors should note that Edison's Q2 2025 core earnings declined 19% year-over-year due to higher operations and maintenance expensesEdison International Reports Second-Quarter 2025 Results^[1]. While this dip highlights exposure to cost pressures, the company's reaffirmed guidance and regulatory flexibility mitigate long-term concerns.
