Resilience

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 65 companies in Semiconductors. The defenses are then weighted to produce the overall score out of 100.
Why is Rambus, 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 Rambus, Inc.?
The Corporate Default template measures 6 defenses, and RMBS scores: Pricing Power (75), Cost Advantage (73), Customer Stickiness (89), Capital Efficiency (72), Resilience (85), Scale & Market Position (88). 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.
