The reading, in brief

Is it good

Return on equity was -165.4% 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 Industrials sector (643 companies), -165.4% sits at the 6th percentile; the middle half of that group runs from -15.6% to 15.8%.

Is it safe

Debt to equity was 0.51 in FY2025, in the band labelled "Within Graham's industrial limit" (0.50 to 1.00), on lines anchored on Graham's defensive-investor criteria.

Today, against the Industrials sector (433 companies), 0.51 sits at the 40th percentile; the middle half of that group runs from 0.28 to 1.21.

The filed income tax is outside 0 to 100% of pre-tax income (a tax benefit on a profit, a charge on a loss, or a charge above the profit), which is a one-off in the tax line and not a rate operating profit was taxed at, so after-tax operating profit is not computed.

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.

More on this company

What this cannot tell you

  • 13 figures could not be read on this company, among them P/E Ratio, EV/EBIT, Return on Invested Capital. Each blank in the table above names the rest, with its reason. 6 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.
