Why it could be worth it
What to watch out for
Nothing stood out in the numbers we check.
This is not advice. Check the numbers below.
For every $100 of what the whole company costs, it produced $2.63 of spare cash in the past 12 months. A savings account pays about $4.
You pay 15.0 years of operating profit for the business. The average large US company costs around 18.
Each dollar kept in the business earns 14 cents a year. Above 10 is good.
Quality score: 81 of 100. Price score: 63 of 100. Our list needs 70 on quality and 60 on price.
$60.16 a share, 4% above its 1-year low
Over the past year the price has ranged from $58.08 to $135.52.
Dividend: 1.7% a year
Paid every year for 4 years
Payouts have jumped around in recent years, so this may not repeat.

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 19 Nov 2025, plus the 10-Q filed 11 Aug 2026 and 9 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.
We may use artificial intelligence, machine learning, data science and similar technologies in our business, and challenges with properly managing such technologies could result in reputational harm, competitive harm, and legal liability, and adversely affect our business, financial condition and results of operations.
Could happenArtificial intelligence, machine learning, data science and similar technologies (collectively, “AI”), including third-party AI tools, may be enabled by, or integrated into, some of our business processes and solutions. As with many developing technologies, AI presents risks and challenges that could affect its further development, adoption, and use, and therefore our business. AI algorithms may be flawed or biased. Datasets used to train or develop AI systems may be insufficient, of inferior quality, or contain biased, incorrect or incomplete information. The utilization of AI may increase our risk and liability exposure relating to confidentiality, intellectual property infringement, and client use restrictions. Our AI governance review process and safeguards may not be adequate to protect against these risks and challenges.

Could happenOur competitors or other third parties may incorporate AI into their product and service offerings more quickly or more successfully than us, which could impair our ability to compete effectively and adversely affect our business, financial condition and results of operations.
Our operations worldwide expose us to legal, political and economic risks in different countries as well as currency exchange rate fluctuations and impacts from inflation that could harm our business and financial results.

Could happenAdditionally, the laws and regulations concerning the use of AI continue to evolve. If the use or integration of AI systems, or the outputs generated by such systems, were determined to be non-compliant (e.g., in relation to AI statutory regimes, data privacy rights or in relation to the use of AI for certain activities or use cases), this may expose us to regulatory action or litigation. It is possible that emerging regulations or changes to intellectual property laws may limit or block the use of AI in our business or otherwise impose restrictions that may adversely affect the efficiency of our business processes or solutions that were utilizing AI technologies.

The deep dive
Everything above is arithmetic on public filings. The deep dive reads the last ten years of annual reports, the proxy statements, and the earnings calls, then argues the case the way Buffett, Klarman, and Hohn would, and checks every claim against the source.
- What the business is worth, as a range, and the margin of safety at today’s price
- Prices to start buying, buy, and buy hard
- The three things that would make this a mistake
- Every number footnoted to the filing it came from
It's near its lowest price in a year. The deep dive tells you if that's a bargain or a warning.
Your first deep dive is free.
