Strategic Shape Diagnostic
Instrument + Consumable
A placed instrument with a required recurring consumable. Device and diagnostics only. The razor-and-blade model creates distinct economics: the instrument is placed (often at cost or below), and the company captures value through consumable pull-through over the installed base lifecycle. This shape has no biopharma analog. The acquirer set, valuation logic, and deal structures are entirely distinct from companies selling standalone devices or diagnostic tests.
Deal Structures
How this shape transacts
Strategic acquisition priced on installed base value and consumable pull-through economics
Installed base transactions where the acquirer values the placed instrument fleet and associated consumable revenue stream
Partnership agreements with exclusivity on consumable supply for placed instruments
Revenue-based valuations tied to consumable recurring revenue, not one-time instrument sales
Contradictions
Common contradictions for IC companies
Contradiction 01
Instrument sales without consumable lock-in — if the instrument works with third-party consumables, the razor-and-blade economics collapse and the shape is not IC
Contradiction 02
Open architecture positioning when the business model requires closed-system consumable attachment
Contradiction 03
Projecting instrument revenue as the primary value driver when the actual value is in consumable pull-through
Counterparty View
What counterparties expect
Acquirers of IC companies evaluate installed base size, consumable attachment rates, contract length, and competitive switching costs. They model consumable revenue per placed instrument over the expected lifecycle and apply recurring-revenue multiples. The critical question is whether the consumable is required or optional — if optional, the IC premium disappears.
