The reading, in brief

Is it cheap

Price to earnings is 46.43x at the close of 2026-10-15 on FY2025 figures; the lines are 15.00x (Graham's defensive ceiling) and, by market convention, 10.00x, 25.00x and 40.00x, and this sits above the highest.

Today, against the Hardware, Equipment & Parts industry (47 companies), 46.43x sits at the 54th percentile; the middle half of that group runs from 27.74x to 71.43x.

Is it good

Return on invested capital was 24.6% in FY2025, in the band labelled "Exceptional" (20.0% and above), on lines anchored on Damodaran's cost-of-capital data, suggesting returns on the capital in the business well above the usual cost of that capital.

Today, against the Technology sector (220 companies), 24.6% sits at the 81st percentile; the middle half of that group runs from 1.2% to 17.5%.

Is it safe

Interest coverage was 15.96x in FY2025, in the band labelled "Comfortable" (6.00x and above), on lines anchored on Damodaran's interest-coverage table, suggesting an interest bill operating profit covers many times over.

The year and the filing date name the statement each figure’s accounts are read from, and they stand even where the figure itself could not be computed: the line beneath a blank says what that statement did not carry. A figure’s name opens its formula and the filings behind it; a statement that names no SEC filing has no filing date, and reads n/a.

What to do with what you have read.

A thesis is your reason for owning it, in your words, with the figures that must stay true. Checking those figures every night against the newest filed accounts, and telling you once when one breaks, is what the subscription adds.

More on this company

What this cannot tell you

And the one that is true of all of it: This is what the numbers say today. It cannot tell you the day one of them stops being true. Nothing here can, because the reasons are not written down.

Running this once is arithmetic on public documents and you are welcome to it. Writing down why you own each company, in your own words and with the numbers that have to stay true for it to hold, and then having those numbers re-checked every night against the newest filed accounts, and against the latest close where a rule watches a price, is Professional, the plan a new account starts on for 30 days, one trial per person. It writes to you the day one breaks, and stays quiet when nothing does. The check runs every night at 23:30 UTC. A filing is picked up the night after it is published.

No card. 30 free days, and nothing is charged unless you choose a plan.

On this page a filed figure opens into its formula, its inputs and the statement, fiscal year and filing date it was read from, and a price into the day of its close. A figure that cannot show that trail says so.
