How the boss is paid
Scott C. James was paid $1.4 million in 2025, about 18 times the typical employee’s pay.
The yearly bonus pays for per-share results:
No — it isn’t tied to per-share results.
The long-term stock award pays for per-share results:
We couldn’t tell from the filing.
Why it matters: new shares can grow total profit while each share earns less. Per-share goals pay the boss only when your slice grows.
From the proxy statement (the company’s yearly voting pack) filed 7 April 2026. Picked out automatically from the company’s own filing. Evidence, not our verdict.
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 4 Mar 2026, plus the 10-Q filed 4 Aug 2026 and 4 later 8-Ks.
One big customer
Worth knowingOne customer brings in a big share of sales: 26% last year. Losing that customer would hurt.
“We sell to a diverse customer base with only one customer representing 10% or more of our consolidated net sales in 2025 (United States Postal Service representing 26%).”
From the 10-K filed 4 March 2026, Item 1. Business. Read it in the filing
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.
Dependence on significant customers could adversely affect our business and results of operations.
Could happenFor the year ended December 31, 2025, our ten largest customers accounted for approximately 52% of our consolidated net sales, with a single customer accounting for 26% of our consolidated net sales. Because our customers’ purchases are made through purchase orders rather than long-term contracts or minimum purchase commitments, order levels can fluctuate significantly from period to period based on customer needs. In addition, significant customers may negotiate more favorable pricing or terms, which may pressure our operating margins. If any significant customer reduces its purchases, loses market share for its end-use products, experiences financial difficulty, changes suppliers, or otherwise alters its relationship with us, demand for our products could decline. Any such reduction in sales could potentially have a material adverse effect on our revenues and results of operations.
