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 24 Feb 2026, plus the 10-Q filed 4 Aug 2026 and 3 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.
Impairment of Goodwill and Intangible Assets.
Already happenedImpairment of Goodwill and Intangible Assets. We evaluate the recoverability of recorded goodwill and other intangible asset amounts annually, or when evidence of potential impairment exists. The annual impairment test is based on several factors requiring judgment. We have experienced impairment charges in the past (refer to Note 1 , Summary of Significant A ccounting and Reporting Policies ) of the Consolidated Financial Statements ). Additional future impairment may result from, among other things, deterioration in the performance of our business or product lines, adverse market conditions and changes in the competitive landscape, and a variety of other circumstances. The amount of any impairment is recorded as a charge to our Consolidated Statement of Income. We may never realize the full value of our goodwill and intangible assets, and determinations requiring impairment charges have had and will continue to have an adverse effect on our financial condition and results of operations.

Could happenThe Company, along with many governments, regulators, investors, employees, customers and other stakeholders, are increasingly focused on environmental, social, and governance considerations relating to our business, including greenhouse gas emissions, human and civil rights and diversity, equity and inclusion. New laws and regulations in these areas have been proposed and may be adopted by varying levels of government, and the criteria used by regulators and other relevant stakeholders to evaluate practices, capabilities and performance are changing rapidly, which in each case could require us to undertake costly initiatives or operational changes. Non-compliance with emerging rules or standards or a failure to address regulator, stakeholder and societal expectations may result in potential cost increases, litigation, fines, penalties, production and sales restrictions, brand or reputational damage, loss of customers, suppliers and commercial partners, failure to retain and attract talent, lower valuation and higher investor activism activities. In addition, we may make statements about our goals and initiatives in this regard through periodic financial and non-financial reports, information provided on our website, press statements and other communications. Managing these considerations and implementing these goals and initiatives involves risks and uncertainties, including increased costs, requires investments and often depends on third-party performance or data that is outside our control. We cannot guarantee that we will achieve any such goals and initiatives we may announce, satisfy all stakeholder expectations, or that the benefits of implementing or achieving these goals and initiatives will not surpass their projected costs. Any failure, or perceived failure, to achieve such goals and initiatives, as well as to manage risks attendant thereto, adhere to public statements, comply with federal, state or international laws and regulations or meet evolving and varied stakeholder expectations and standards could result in legal and regulatory proceedings against us and materially adversely affect our business, financial condition or results of operations.
Read moreBiometrics Market.
Could happenBiometrics Market. A component of the Company's growth strategy includes expansion of our biometric technology and solutions into commercial markets. Although the use of biometric readers on popular consumer products, such as smartphones, has increased interest in biometrics as a means of authenticating and/or identifying individuals, commercial markets for biometrics technology are still developing and evolving. Biometrics-based solutions compete with more traditional security methods including keys, cards, personal identification numbers, fingerprints, and security personnel. Acceptance of biometrics as an alternative to such traditional methods depends upon a number of factors, including: the cost, performance and reliability of our products and services and the products and services offered by our competitors; customers’ perceptions regarding the benefits of biometrics solutions; public perceptions regarding the intrusiveness of these solutions and the manner in which organizations use the biometric information collected; public perceptions regarding the confidentiality of private information; proposed or enacted legislation related to privacy of information; customers’ satisfaction with biometrics solutions; and marketing efforts and publicity regarding biometrics solutions.

Could happenA considerable number of established companies have developed or are developing and marketing software and hardware for biometrics products and applications, including facial recognition, fingerprint biometrics, and other iris authentication competitors that currently compete with, or will compete directly with, our biometric authentication solutions. We expect that additional competitors will enter the biometrics market and become significant long-term competitors, and that as a result, competition will increase. Companies competing with us may introduce solutions that are competitively priced, have increased performance or functionality or incorporate technological advances we have not yet developed or implemented. There is no assurance the Company will be successful in this area.

Our allowance for credit losses applicable to trade accounts receivable primarily relate to financially distressed automotive mirror and electronics customers. We continue to work with financially distressed customers in collecting past due balances. Our allowance for credit losses applicable to loans receivable reflect the Company's estimate of expected credit losses over the contractual life of the loans, considering historical loss experience, current conditions, and reasonable and supportable forecasts. Refer to Note 1 , Summary of Significant Accounting and R eporting Policies of the Consolidated Financial Statements .
