From Form 4 filings: insiders must report trades in their own company's shares within two days.

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 6 Feb 2026, plus the 10-Q filed 31 Jul 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.

  • Risks Related to Financial, Legal and Regulatory Matters

    Could happen
    13/ATR 2025 Form 10-K We are exposed to risks from lawsuits and claims, including product liability claims, as well as investigations, audits and other proceedings, which may result in substantial costs and expenses or interruption of our normal business operations. We are subject to a number of lawsuits and claims that arise in the ordinary course of our business, which include intellectual property infringement, product liability, commercial, employment, tort, business interruption and other litigation. For example, in May 2025, Nemera filed patent infringement actions against us in France and Germany relating to certain of our ophthalmic products. In October 2025, an EPO hearing invalidated Nemera’s main patent claim while allowing an amended claim to continue. In addition, in September 2025, ARS Pharmaceuticals Operations, Inc. filed an antitrust lawsuit against us in the United States District Court for the Southern District of California, alleging violations of U.S. competition laws related to supply of certain components and are seeking injunctive relief and damages. Refer to Note 13 – Commitments and Contingencies of the Notes to the Consolidated Financial Statements for additional information regarding these actions We are also subject to indemnification claims under various contracts. Further, the failure of our products to operate as intended may result in a product liability claim against us. We believe we maintain adequate levels of product liability insurance coverage and robust quality control systems at our facilities. However, a product liability claim in excess of our insurance coverage or not covered by existing insurance may materially adversely affect our business, results of operations or cash flows.

  • Risks Related to Financial, Legal and Regulatory Matters

    Could happen
    We are also from time to time subject to claims from third parties suggesting that we may be infringing on their intellectual property rights. For example, in May 2025, Nemera filed patent infringement actions against us in France and Germany relating to certain of our ophthalmic products. In October 2025, an EPO hearing invalidated Nemera’s main patent claim while allowing an amended claim to continue. Refer to Note 13 – Commitments and Contingencies of the Notes to the Consolidated Financial Statements for additional information.

  • Risks Related to Our Operations and Industry

    Could happen
    11/ATR 2025 Form 10-K A material failure or disruption at one or more of our manufacturing facilities could adversely affect our ability to generate sales and meet customer demand. Our ability to generate sales and meet customer demand depends on the continued operation of our manufacturing facilities, many of which involve complex, specialized, and highly regulated manufacturing environments, including clean-room operations. A material failure or disruption at one or more of these facilities could occur for a variety of reasons, including significant equipment or mechanical failures, information technology or systems outages, cybersecurity incidents, power interruptions, fires, explosions, natural disasters, extreme weather events, labor disruptions, public health events, or other causes beyond our control.
