Warning signs in its filings

Problems the company itself reported to the SEC, in its own words.

None of the warning signs we check for were found.

We look for five warning signs: doubt it can keep going, weak checks on its own accounts, a notice that its past accounts can't be relied on, a change of auditor, and one customer bringing in a big share of sales. We don't check lawsuits, investigations or debt yet.

We checked the auditor's report, internal controls, restatement notices, auditor changes and big customers in the 10-K filed 27 Feb 2026, plus the 10-Q filed 5 Aug 2026 and 8 later 8-Ks.

A 10-K is the yearly report every US company files with the SEC. An 8-K is a short notice of a big event.

What could go wrong

Cheap for a reason is the question the numbers cannot answer.

Whether the price already reflects the risks is what the deep dive is for.

What changed in the risks this year

Companies must list what could hurt them each year. These are the parts that changed since last year’s report.

  • Our results of operations may be adversely affected if doctors at DSOs, orthodontic service organizations (“OSOs”) or other large group practices reduce, delay, or do not increase their purchasing of our products and services in ways that reduce adoption of our products and services.

    Could happen
    DSOs, OSOs and other large group practices have become an increasingly important channel for adoption of our products and services. If doctors at DSOs, OSOs or other large group practices reduce, delay, or do not expand their purchasing of our products and services, or otherwise change priorities, protocols, or workflows in ways that reduce utilization of our products, demand for our products and services may not increase or may decrease, which could have a material impact on our business, financial condition and results of operations. In addition, on behalf of the doctors in their affiliated practices, DSOs and other large group practices may have greater leverage to negotiate pricing, volume‑based discounts, rebates, extended payment terms, or other commercial concessions, which could adversely affect our ASPs, gross margins and profitability.

  • Geopolitical events, tariffs and trade policies, and military conflicts have and could in the future materially affect our business, financial condition and results of operations .

    Tariffs or proposed tariffs, customs duties, or fees, and any retaliatory tariffs, international trade disputes, or protectionist trade measures taken in response to such tariffs may increase the cost of our products and the components or the raw materials used to make them, reduce demand for our products and adversely impact our gross margin and results of operations, limit our ability to sell to certain customers, limit or prohibit the availability of certain raw materials, components and parts necessary for our products or the products of our suppliers, or impede or slow the movement of our goods across borders. For example, the U.S. Department of Commerce has initiated an investigation under Section 232 of the Trade Expansion Act of 1962, as amended, to determine the effects on the national security of imports of personal protective equipment (PPE), medical consumables, and medical equipment including devices. A significant portion of the products we sell, and the components and raw materials used in our products are originally manufactured or sourced outside the United States. For example, we manufacture clear aligners in our facility in Mexico and ship them to the United States, primarily for our United States customers, with the remainder eventually shipped to other international locations. Tariffs have and could in the future result in additional costs for our products, which may reduce demand for our products and adversely impact our gross margin and results of operations, and we may not be able to fully or substantially mitigate the impact of any new or increased tariffs or pass price increases on to our customers and to the extent we do, we may experience reduced demand for our products. The extent and duration of any tariffs and the resulting impact on general economic conditions and on our business, financial condition and results of operations are uncertain.

  • Our quarterly and annual results of operations have and will continue to fluctuate in the future, and we may not accurately predict the timing and amount of customer demand and our revenues, costs, and expenditures.

    • changes in the timing of revenue recognition and our ASPs as a result of changes to the amount allocated to the standalone selling price of the distinct performance obligations under sales contracts;
  • AI and machine learning technologies in our products, services and IT systems may result in legal and regulatory risks, reputational harm or have other adverse consequences to our business.

    Could happen
    Additionally, as we offer more third-party AI models in our solutions, we face risks inherent in how third-party AI models used in our solutions have been developed and deployed, including situations in which the third party may lack a proper license or consent for the training data used for their model. The use and availability of third-party AI models in our solutions could result in scrutiny and legal liability, including intellectual property infringement claims. Such claims or scrutiny could cause reputational harm and loss of customers, and adversely impact our business and financial results. In addition, new competition regulations on AI development and deployment could impose new requirements on our markets that could impact our business and financial results.

  • Current and anticipated sustainability and social (“Sustainability”) laws and scrutiny of our Sustainability policies and practices may materially increase our costs, expose us to liability, and adversely impact our reputation, employee retention, willingness of customers and suppliers to do business with us and willingness of investors to invest in us.

    Could happen
    Our operations are subject to rapidly changing and varied expectations and requirements regarding Sustainability issues from a wide range of stakeholders, such as governmental and self-regulatory organizations, including U.S. federal and state governments, and the EU, as well as investor advocacy groups, institutional investors, investment funds, proxy advisory services, stockholders and customers. We are also required to comply with disclosure obligations under the SEC’s long-standing climate change disclosure guidance and other SEC regulations, as well as the European Union’s Corporate Sustainability Reporting Directive (“CSRD”). If we fail to adopt Sustainability standards or practices as quickly as stakeholders desire, comply with or timely report on our Sustainability efforts or practices accurately, or satisfy the disclosure and other expectations of stakeholders, our brand, reputation, employee retention, business, financial performance, growth, and stock price may be adversely impacted.
