Align Technology, Inc. (ALGN)

How it makes money

Align earns Clear Aligner revenue per treatment case: a doctor orders a set of custom aligners, Align manufactures and ships them, and revenue is recognized as trays are delivered over the course of treatment. Systems and Services revenue comes from selling or leasing iTero scanners plus recurring CAD/CAM software and service fees. Because key aligner patents began expiring in 2017, pricing power now rests more on brand recognition, the doctor-training network and scanner ecosystem than on legal exclusivity.

Revenue by segment

Invisalign is the name patients ask for by default, built over two decades of marketing and a large trained network of certified doctors. But the aligner patents that once blocked competitors began expiring in 2017, and cheaper rivals plus direct-to-consumer and in-office 3D-printed alternatives have since chipped away at both volume growth and pricing.

Straightening teeth is largely elective and often paid out of pocket or through limited dental insurance, so case volumes soften when consumers pull back discretionary spending. Growth also depends on expanding into new international markets and younger teen patients, both of which move independently of any single economic cycle but are still sensitive to household budgets.

Key risks

• Patent expiry and low-cost competition — Key clear-aligner patents have expired in the US and abroad, letting lower-priced rivals and direct-to-consumer aligner services compete for the same patients and pressure the prices Align can charge.
• Discretionary consumer spending — Orthodontic treatment is often optional and expensive, so case starts slow when consumers are cautious about spending, even if their teeth alignment need has not changed.
• International and China exposure — A meaningful part of growth depends on international markets, including China, where local competitors, economic slowdown or regulatory change can reduce case volume independent of trends in the US.
• Intellectual property litigation — Align is involved in ongoing patent and other IP disputes with competitors and doctors; adverse rulings could restrict product features or require payments that reduce profitability.

Align sells to hundreds of thousands of orthodontic and dental practices worldwide rather than a few large accounts, so no single customer represents a material share of revenue.
