Fixed Costs Trap in Retail Healthcare
Carbon Health
The hard part in retail healthcare is not opening clinics, it is keeping each box busy enough to cover rent, clinicians, billing friction, and payer mix. Carbon built roughly 120 clinics around a software driven model, but the business still depends on mature site level volume and better reimbursement, and new clinics can take 18 to 24 months to stabilize. Walgreens and VillageMD show what happens when footprint grows faster than clinic economics mature.

Carbon is trying to offset clinic cost with software. Its app handles booking and follow ups, and CarbyOS ties scheduling, charting, and billing together. Carbon says ambient scribing cut note time by about 75% and lifted throughput around 30% in pilots, which matters because labor is the biggest controllable clinic cost.

The core economic trap is fixed cost. Carbon states that leases, staffing, and compliance do not flex down quickly, and it was still losing $64 per patient visit. That means adding locations can grow losses before it grows profit, especially after pandemic testing revenue disappeared and the business had to rely on urgent care, primary care, and virtual visits.

CVS has a structurally easier model because it can funnel patients from Aetna into MinuteClinic and Oak Street Health, and keep margin across insurance, clinics, and pharmacy. Walgreens took the opposite lesson from VillageMD, recording a $3.3 billion operating loss tied to impairment and lower forecasts, while clinic closures reduced VillageMD revenue.
Going forward, the winners in retail healthcare will look less like store rollouts and more like tightly tuned care networks with software that squeezes more visits and more follow on care out of each site. For Carbon, that points toward fewer pure expansion bets and more focus on densifying existing markets, payer contracts, chronic care programs, and licensing its operating system into larger footprints like CVS.
