Remaining Performance Obligations

ASC 606, Revenue from Contracts with Customers, requires disclosure of remaining performance obligations that represent the aggregate transaction price allocated to performance obligations with an original contract term greater than one year which are fully or partially unsatisfied at the end of the period. Remaining performance obligations include noncancelable purchase orders, unfulfilled obligations, extended warranty and service agreements and do not include revenue from contracts with customers with an original term of one year or less.

With respect to certain clear aligner treatment plans, the Company enters into contracts that involve multiple future performance obligations which include optional additional aligners at no additional charge. The Company’s treatment plans are comprised of the following performance obligations: initial aligner shipment and the subsequent shipments of any optional refinement aligners. For such plans, the Company also consider usage rates, which is the number of times a customer is expected to order additional refinement aligners.

At September 27, 2024, the aggregate amount of the transaction price allocated to remaining performance obligations was $126.7 million, including $93.6 million related to clear aligner treatment plans. The Company expects to fulfill the majority of these performance obligations over the next 12 months.

Contract Liabilities

The Company often receives cash payments from customers in advance of the Company’s performance resulting in contract liabilities. These contract liabilities are classified as either current or long-term in the Condensed Consolidated Balance Sheets based on the timing of when the Company expects to recognize revenue. As of September 27, 2024 and December 31, 2023, the contract liabilities were $158.0 million and $114.8 million, respectively, and are included within accrued expenses and other liabilities and other long-term liabilities in the accompanying Condensed Consolidated Balance Sheets.
