Moat scores for companies ranked near WST in Medical Instruments & Supplies
How WST scores on the Medical Devices & Diagnostics defenses
Pricing Power & Consumable Moat
Score 37
· 25% of the moat score
In MedTech, pricing power is rarely about the machine — it is about what the machine consumes.
R&D Pipeline & Capital Returns
Score 79
· 20% of the moat score
Research spending is how a device company keeps its installed base current, but spending alone proves nothing.
FCF Quality & Cash Conversion
Score 68
· 20% of the moat score
MedTech companies grow by acquisition, and the resulting intangible amortisation depresses reported earnings without consuming any cash.
Commercial Execution
Score 65
· 15% of the moat score
Devices are sold into hospitals and labs through committees, tenders and long qualification cycles, which makes the sales organisation expensive and hard to replicate.
Capital Structure & Resilience
Score 84
· 12% of the moat score
Serial acquirers carry debt, and the question is whether the cash flows underneath it are dependable enough to service it through a downturn.
Growth Durability
Score 67
· 8% of the moat score
Growth durability separates an expanding installed base from a good product cycle.

How is the moat score calculated?
Each company is scored with an industry-specific template — Medical Devices & Diagnostics 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 61 companies in Medical Instruments & Supplies. The defenses are then weighted to produce the overall score out of 100.
Why is West Pharmaceutical Services, I scored with the Medical Devices & Diagnostics template?
Medical device and diagnostics companies place an instrument once and then sell the consumables, reagents and service that instrument needs for the next decade. The economics are a razor-and-blade model wrapped in regulatory approval and clinician habit, so the MedTech template scores the durability of that installed base rather than the size of any single product launch.
Which competitive defenses are measured for West Pharmaceutical Services, I?
The Medical Devices & Diagnostics template measures 6 defenses, and WST scores: Pricing Power & Consumable Moat (37), R&D Pipeline & Capital Returns (79), FCF Quality & Cash Conversion (68), Commercial Execution (65), Capital Structure & Resilience (84), Growth Durability (67). 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.
