The business, and the score behind its five axes

The reading, in brief

Is it cheap

Price to earnings is 81.43x 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 Basic Materials sector (124 companies), 81.43x sits at the 92nd percentile; the middle half of that group runs from 15.03x to 34.97x.

Is it good

Return on equity was 5.2% in FY2025, in the band labelled "Likely below the cost of equity" (below 8.0%), on lines anchored on Damodaran's cost-of-capital data, suggesting returns on shareholders' money below the usual cost of equity.

Today, against the Basic Materials sector (247 companies), 5.2% sits at the 61st percentile; the middle half of that group runs from -20.2% to 11.8%.

Is it safe

Current ratio was 1.97 in FY2025, in the band labelled "Adequate" (1.50 to 2.00), on lines anchored on Graham's defensive-investor criteria.

Today, against the Basic Materials sector (251 companies), 1.97 sits at the 42nd percentile; the middle half of that group runs from 1.42 to 3.59.

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.

Next step

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

  • 12 figures could not be read on this company, among them Debt to Equity, EV/EBIT, Return on Invested Capital. Each blank in the table above names the rest, with its reason. 5 named tests come back incomplete because of them, which is neither met nor missed.

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.

ValueScreener · valuescreener.ai · Computed from accounts filed with the SEC by this company, read from EDGAR, and from dated closing prices. 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.

A computation on accounts filed with the SEC, not a recommendation and not advice. Past filings do not indicate future results. Risk disclaimer.

Margin Notes
