Sunrun (RUN) Looks Cheap After Revenue Beat And Battery Uptake Strength

Simply Wall St·10/15/2026 06:31:51
Listen to the news

Sunrun (RUN) recently reported revenue of US$870 million for the quarter, up 52.8% year on year, beating analyst forecasts on both sales and earnings and drawing attention to its battery attachment trends.

Sunrun's strong quarterly update landed against a weak tape for the stock, with the share price down about 40% over the past three months and roughly 62% lower year to date despite the recent earnings beat and battery attachment progress. That drop in the 90 day share price return and a 66% decline in the 1 year total shareholder return suggest momentum has been fading as investors reassess both growth potential and risk around residential solar and financing conditions.

Sunrun now trades at a deep discount to the average analyst price target, even after strong reported growth and battery uptake. Is the current markdown a sign of sensible caution on residential solar risk, or an opportunity the market is mispricing?

Most Popular Sunrun Narrative: 72% Undervalued

Sunrun last closed at $7.30, while the most followed narrative pegs fair value around $25.90 using a 12.54% discount rate. That gap reflects a view that the market price is not fully capturing potential from storage, virtual power plants, and new AI backed use cases.

While analysts broadly expect product mix optimization and storage attachment to support revenue growth and margins, the current trajectory, with storage attached to 70% of new installations and almost triple the prior year's grid service enrollments, suggests Sunrun could participate meaningfully in emerging home-to-grid markets and realize a multi-year uplift to recurring revenue relative to existing projections.

See why 7 investors see Sunrun as 72% undervalued.

Result: Fair Value of $25.90 (UNDERVALUED)

Still, that bullish Sunrun narrative can unravel quickly if policy support fades faster than expected or if higher funding costs squeeze its capital intensive model.
