9. Commitments and contingencies

Purchase obligations

The Company had approximately $58,800 of outstanding purchase orders due within one year with its outside vendors and suppliers as of September 30, 2025. The Company has $762 and $672 accrued within accounts payable and other accrued expenses in the consolidated balance sheet as of September 30, 2025 and December 31, 2024, respectively, related to estimated losses for firm commitment contractual obligations under these agreements. Losses on these firm commitment contractual obligations are recognized based upon the terms of the respective agreement and similar factors considered for the write-down of inventory, including expected sales requirements as determined by internal sales forecasts.

Warranty obligation

Contract liabilities

Contract liabilities primarily consist of deferred revenue related to lifetime warranties on direct-to-consumer sales revenue when cash payments are received in advance of services performed under the contract. The contract with the customer states the final terms of the sale, including the description, quantity, and price of each product or service purchase. The decrease in deferred revenue related to lifetime warranties for the nine months ended September 30, 2025 was primarily driven by $3,240 of revenue recognized that were included in the deferred revenue balances as of December 31, 2024, partially offset by $922 of payments received in advance of satisfying performance obligations. Deferred revenue related to lifetime warranties was $7,604 and $9,922 as of September 30, 2025 and December 31, 2024, respectively, and is classified within deferred revenue - current and noncurrent deferred revenue - noncurrent in the consolidated balance sheets.

Legislation and HIPAA

The healthcare industry is subject to numerous laws and regulations of federal, state, and local governments. These laws and regulations include, but are not necessarily limited to, matters such as licensure, accreditation, government healthcare program participation requirements, reimbursement for patient services, and Medicare and Medicaid fraud and abuse. Compliance with government laws and regulations can be subject to future government review and interpretation as well as regulatory actions unknown or unasserted at this time. The Health Insurance Portability and Accountability Act of 1996, or HIPAA, was enacted to ensure health insurance portability, reduce healthcare fraud and abuse, guarantee security and privacy of health information, and enforce standards for health information. The Health Information Technology for Economic and Clinical Health Act, or the HITECH Act, in part, imposes notification requirements of certain security breaches relating to protected health information. The Company is not aware of any pending claims against it under the HIPAA and HITECH regulations that are applicable to the Company’s business.

Legal proceedings

On March 3, 2023, APT Electronics Inc., or APT, filed a lawsuit in the Superior Court of the State of California, County of Orange against the Company, or the APT Action. APT alleged that the Company failed to pay APT for all services, inventory, and materials due to it in connection with the parties’ prior supply arrangement. APT sought damages, pre-judgment interest, costs, and attorneys’ fees.

The parties reached a mutually agreeable settlement in August 2025. The Company paid $1,750 to APT on August 26, 2025, finalizing the payment of this settlement and incurred $668 in legal settlement costs, both classified within general and administrative expense. Based on the parties’ request, the court dismissed the APT Action with prejudice on August 27, 2025. Although the Company came to a settlement agreement to remove the risk of uncertain legal and financial obligations going forward, the Company in no way assumed or admitted any wrongdoing.

The Company is party to various legal proceedings and investigations arising in the normal course of business. The Company carries insurance, subject to specified deductibles under the policies, to protect against losses from certain types of legal claims. At this time, the Company does not anticipate that any of these other proceedings arising in the normal course of business will have a material adverse effect on the Company’s business. Regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources, and other factors.
