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 serious warning signs we check for were found. 1 thing worth knowing.

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 25 Feb 2026, plus the 10-Q filed 11 Aug 2026 and 5 later 8-Ks.

  • Changed auditor

    Worth knowing

    The company changed its auditor (the firm that checks its books) in the last two years.

    Cover page of the 10-K filed 25 Feb 2026: it names a different audit firm from the one named in the annual report before.

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.

  • Changes in foreign trade policies and tariffs may adversely impact our business, financial condition, and results of operations.

    Could happen
    Various countries have announced or implemented retaliatory measures in response to U.S. trade actions, which could further complicate our international operations and supply chain. For example, the carpet tile we sell in Canada typically is manufactured at our plant in the U.S., and therefore may be subject to tariffs implemented by Canada on imports from the U.S. The current situation remains dynamic, and it is unknown if the U.S. and its trade partners will reach agreements to pause or eliminate currently enacted, pending, and threatened tariffs.

  • Disruptions to or failures of information technology systems we use could adversely affect our business.

    Could happen
    Any events which deny us use of vital IT systems may seriously disrupt our normal business operations. These disruptions may lead to production or shipping stoppages, which may in turn lead to material revenue loss and reputational harm. These cyber threats are diverse and constantly evolving, especially given the advances in, and the rise of the use of, artificial intelligence, thereby increasing the difficulty of preventing, detecting, and successfully defending against them and may be more difficult to detect and mitigate, including as threat actors use artificial intelligence and other advanced tools to enhance attacks and impersonation tactics. Cybersecurity breaches could, among other things, disrupt our operations or result in the unauthorized disclosure, theft and misuse of company, customer, employee and supplier sensitive and confidential information, all of which could adversely affect our financial condition and results of operations. Cybersecurity breaches could also result in legal claims or proceedings, financial liability to other parties, governmental investigations, regulatory enforcement actions and penalties, and damage to our brand and reputation. Although we maintain insurance coverage relating to cybersecurity incidents, we may incur costs or financial losses that are either not insured against or not fully covered through our insurance and such insurance may be subject to exclusions, sub-limits and retentions and may become more expensive or less available on acceptable terms.

  • Disruptions to or failures of information technology systems we use could adversely affect our business.

    Could happen
    • software “bugs”, hardware defects or human error or malfeasance; and • hacking, computer viruses or malicious codes, denial of service attacks, malware, ransomware, unauthorized access attempts, social engineering schemes, credential theft, phishing scams, compromised or irretrievable backups, exploitation of vulnerabilities in third-party software and systems or other cyber-attacks.
    Read more
  • Sales of our principal products have been and may continue to be affected by adverse economic conditions and cycles, and effects in the new construction market and renovation market.

    Unfavorable economic conditions may arise during times of U.S. and international economic downturns, or may be attributed to government shutdowns, implementation of new or increased tariffs and ongoing changes in U.S. and foreign government trade policies (including potential modifications to existing trade agreements and retaliatory measures by foreign governments), inflationary or deflationary pressures, natural disasters, severe weather events, calamities, public health crises, political or civil unrest, terrorist acts, and global conflicts. These macroeconomic conditions have at times, and could in the future, adversely affect the demand for our product offerings.
