Sunrun

▲ Bull Case

• ◆Rate normalization unlocks securitization economics: Fed reaches terminal rate 3.5–4.0% by end-2026; 10-yr Treasury below 4.0%. ABS spreads tighten 60 bps. Per-customer securitization proceeds rise $1,500–$2,000. NSV crosses $13,000/customer by 2027. Equity FCF reaches +$450M by 2028, +$700M by 2030.
• ◆Battery attach rate hits 55% nationally by 2027, driving NSV uplift and VPP optionality: Section 48E standalone storage ITC + battery cost deflation drive faster adoption. Each battery customer adds $3,000–$5,000 NPV vs solar-only. VPP becomes a real revenue line at $150M+ ARR by 2028. Re-rates Sunrun from depressed solar installer to grid infrastructure provider—opens 8–12x EV/EBITDA infrastructure multiples.
• ◆Industry consolidation accelerates with Sunrun as the consolidator: SunPower bankruptcy leaves ~100–150K customers needing O&M operator; Sunnova continues distressed. Sunrun acquires portfolios at $6,000–$10,000/customer vs $23,000 COCA—accretive deals add ~$0.5B equity value. Market share climbs to 22–25%. Composite fair value reaches $25–$32 (+50–90% upside).

▼ Bear Case

• ◆Rates stay elevated; equity raise required: 10-yr Treasury holds at 4.75–5.25% through 2027. Fed pauses cuts. ABS spreads stay above SOFR+225. NSV stalls at $4,000–5,000/customer. Equity FCF stays negative through 2030; cumulative burn ~$700M. Forces $300–400M equity raise at $10–12/share in 2027—diluting another ~25M shares. Stock re-rates to $11–13.
• ◆IRA ITC reduced to 22% via budget reconciliation: Section 48 base ITC cut from 30% to 22% in mid-2027. Tax equity proceeds fall ~$2,000 per customer; NSV compresses by ~$160M/yr at 80K installs. Domestic content adder eliminated. Industry-wide repricing of solar economics. Stock declines to $9–11.
• ◆NEM 3.0 spreads + COCA stays elevated: Florida and/or Texas adopt California-style export rate reductions in 2026–2027. Forces battery bundling at +$2,000 COCA in those states; volume drops 25–30%. Structural labor cost inflation offsets panel deflation. COCA stays at $21,000–$22,000. NSV at $3,000–$4,000 keeps origination marginally value-destructive. Stock at $7–10.

“Three live debates among 18 covering analysts: (1) Discount rate appropriateness—Bulls argue 5–6% is appropriate for contracted cash flows; Bears argue 8–10% given risks. This debate explains most dispersion in price targets ($14 low / $25 high) around $18.92 average. (2) When does equity FCF go positive?—Bulls expect 2025–2026; consensus 2026E; conservatives 2027–2028+. Each 6-month slippage compresses equity DCF by ~$1.50/share. (3) Strategic value of VPP—Bulls view as 5–10x revenue optionality for re-rating; Bears view as years away with uncertain business model and payment structures still being defined by CPUC, CAISO, FERC.”

• ◆Fed funds rate cuts and 10-yr Treasury below 4.0%—directly improves securitization economics; visible quarterly
• ◆Quarterly NSV and battery attach disclosures—NSV > $8K and battery attach > 40% are bull signals
• ◆SunPower portfolio resolution—distressed customer portfolio in play; accretive M&A opportunity
• ◆Battery attach hits 50% nationally by 2027—Section 48E and cost deflation drive adoption; re-rates NSV
• ◆First equity-FCF-positive quarter—major narrative inflection; sentiment re-rating catalyst
• ◆IRA durability confirmation post-2024 election—removes the largest policy overhang

• ◆Interest rates stay elevated (Moderate probability, Severe impact): 10-yr Treasury at 4.75–5.25% through 2027; Fed pauses cuts; ABS spreads remain above SOFR+225. NSV stalls; equity FCF stays negative through 2030; cumulative cash burn ~$700M.
• ◆COCA inflation and cost discipline failure (Moderate probability, Severe impact): Structural labor cost inflation; operational cost growth keeps COCA at $21,000–$22,000. Origination engine remains marginally value-destructive.
• ◆IRA Section 48 ITC reduced below 22% (Low probability, Catastrophic impact): Foundational to business economics. Cut from 30% to 22% compresses NSV ~$160M/yr. Any reduction below 22% forces fundamental business model restructuring.
• ◆Capital markets dislocation (Low probability, Catastrophic impact): Tax equity or ABS market closure for 6+ months. Sunrun relies on ~$3–4B annual funding from these sources. Markets have closed before (March 2020).
• ◆NEM 3.0 spreads to Florida, Texas, or NY (Moderate probability, Significant impact): California-style export rate reductions contract Sunrun's largest non-California growth markets. Forces battery bundling at +$2,000 COCA; volume drops 25–30%.
