What the numbers show

Operating cash flow was below net income in 2 of 4 profitable years shown (Oct 2023, Oct 2022).
Revenue fell in 1 of the last 4 fiscal years shown (Nov 2024).
Operating margin was 6.1% in Oct 2022 and 4.1% in Nov 2025.
Weighted average shares decreased 5.9% between Oct 2022 and Nov 2025.

Worth a closer look

Automatic checks on the figures above. A flag is a pattern to investigate, not a finding of wrongdoing, and each one lists ordinary explanations for it.

Operating margin shrinking

Operating margin fell from 8.2% in Oct 2023 to 4.1% in Nov 2024 and 4.1% in Nov 2025.

Operating income	Nov 2025	$198M
Revenue	Nov 2025	$4.8B
Operating income	Nov 2024	$167M
Revenue	Nov 2024	$4.0B
Operating income	Oct 2023	$358M
Revenue	Oct 2023	$4.4B

How it's calculated: Operating margin = operating income ÷ revenue, for each year.

Rule: Operating margin lower in each of the last two years, down 3 percentage points or more in total.

Why it matters, and ordinary explanations

Why it can matter: A margin that keeps shrinking can mean costs are rising faster than prices, or that the company is losing pricing power.

Common innocent explanations: Deliberate investment in growth, a shift in the mix of products, or one-off charges that depress a single year.

Rules checked

Revenue up, operating cash flow down — not triggered. Revenue up 5% or more in the latest year while operating cash flow fell 10% or more.
Profit not matched by cash — not triggered. Net income positive, but operating cash flow below 70% of net income in each of the last two fiscal years.
Receivables growing faster than revenue — not run. Not enough comparable annual figures reported to run this check.
Share count rising — not triggered. Weighted average shares up 5% or more in a year, or 10% or more over three years.
Operating margin shrinking — flagged. Operating margin lower in each of the last two years, down 3 percentage points or more in total.

Source: SEC EDGAR annual reports (Form 10-K), latest filed 2025-12-12. If a company later restates a year, the most recent filing is used. Dashes mean the company did not report that line in a form we could read. For information only, not investment advice.
