How RUN scores on the Corporate Default defenses

Pricing Power

Score 27 · 20% of the moat score

Pricing power is the ability to raise prices without losing volume.

Cost Advantage

Score 46 · 15% of the moat score

A cost advantage means delivering the same product for structurally less — better purchasing, denser distribution, a more automated process.

Customer Stickiness

Score 44 · 15% of the moat score

Stickiness is what makes revenue repeat without being re-won every year.

Capital Efficiency

Score 39 · 18% of the moat score

Capital efficiency asks what the company earns on the money tied up in the business.

Resilience

Score 43 · 17% of the moat score

Resilience is the capacity to get through a bad year on its own terms — enough liquidity, enough interest cover, and enough cash generation to avoid a rescue financing or a forced sale.

Scale & Market Position

Score 48 · 15% of the moat score

Scale matters only when it converts into economics.

How does Sunrun Inc. compare with other Solar companies?

How is the moat score calculated?

Each company is scored with an industry-specific template — Corporate Default in this case, chosen because the defenses that matter to a bank are not the ones that matter to a software company. Every defense combines several financial signals, and each signal is measured as a percentile against a peer group of 27 companies in Solar. The defenses are then weighted to produce the overall score out of 100.

Why is Sunrun Inc. scored with the Corporate Default template?

Most public companies sell a product or a service at a margin, so the moat question is whether that margin survives contact with competitors. The Corporate template scores the six defenses that show up in a general operating company's financial signature: whether it can hold price, produce more cheaply than rivals, keep its customers, earn a return above its cost of capital, withstand a downturn, and turn size into economics.

Which competitive defenses are measured for Sunrun Inc.?

The Corporate Default template measures 6 defenses, and RUN scores: Pricing Power (27), Cost Advantage (46), Customer Stickiness (44), Capital Efficiency (39), Resilience (43), Scale & Market Position (48). Each is scored independently as a percentile against peers, so a company can be strong on one and weak on another — the overall score reflects how those defenses are weighted for this industry.
