Sunrun (RUN) is back in focus after reporting full year 2025 results that moved from a multibillion dollar loss to US$449.95 million in net income, along with continued progress in grid services and financing partnerships.

Despite the return to profitability and progress in grid services partnerships, Sunrun’s recent share price has come under pressure. The 7 day share price return is 42.26% and the 30 day share price return is 36.17%, while the 1 year total shareholder return of 71.62% contrasts with the 3 year total shareholder return of 50.13% and the 5 year total shareholder return of 81.42%. This suggests that short term momentum has cooled after a sharp rebound from earlier years’ declines.

With Sunrun back in the black and the share price still well below its recent highs, the central question is whether investors are underappreciating this reset or whether the market has already priced in the earnings turnaround and grid services growth.

Most Popular Narrative: 48.1% Undervalued

With Sunrun closing at $11.79 and the most followed narrative pointing to a fair value of $22.74, the gap between price and narrative expectations is wide.

Sunrun is rapidly scaling its storage and grid services offerings, enrolling a growing portion of its customer base (currently ~35% of 200,000 batteries, aiming for 10 GWh of dispatchable energy by 2029). This enables significant recurring revenue growth and expanded margin opportunities as demand for grid support rises, and is expected to positively impact long-term revenue and net margins.

Curious how this valuation leans so far above today’s price? The narrative leans heavily on recurring revenue, thicker margins, and an earnings profile that differs from the past.

The most popular narrative applies a 12.5% discount rate to future cash flows and margins, then arrives at a fair value that sits well above the current share price. It leans on projections for revenue expansion, improving profitability and an earnings profile that differs from recent results, while also factoring in policy incentives and financing access as key inputs to long term value.

Result: Fair Value of $22.74 (UNDERVALUED)

However, you still need to weigh the risk that key tax credits roll off faster than Sunrun can adapt, or that tighter financing conditions pressure its capital intensive model.
