Quarter flow (concentrated managers)

Change in managers (1 → 1): 0 opened · 0 exited = 0

Net flow in the quarter: $0K (0 shares) · bought $0 and sold $0Shares concentrated managers added minus those they cut, valued at the 13F quarter-end implied price, not each trade's price. It is a different measure from the change in managers: the two can have opposite signs.

Accumulation: combined they have held more shares for 7 quarters in a row (0 added, 0 trimmed). It is the combined share count of those still holding it: one large buyer can outweigh many who trimmed.

Quality vs sector
—

Figures come from the latest annual report: we do not compare them with its sector's, which are 12-month figures to the latest quarter. Debt includes leases: under IFRS 16 they are all on the balance sheet and their cost sits outside EBITDA.

This company's sector comes from its SIC code, unreviewed, or has too few comparable companies: we do not compare it with its sector.

Figures from the statements the company filed with the SEC (40-F). Free cash flow = operating cash flow − capital expenditures; empty if the company does not report capex. “Quality vs sector”: 0 to 100, the average of its percentiles in ROE, operating margin, free-cash-flow margin, revenue and earnings growth and net debt / EBITDA (at least 3 needed) against companies in its sector above $300M.

From the statements the company filed with the SEC (10-K). The change compares average diluted shares of each fiscal year, on today's basis: negative = it bought back more than it issued; positive = dilution. “No data” = the company does not report that item under a tag we can read; it does not mean zero.

Earnings quality and debt

Operating cash flow ÷ net income (12 months)

Debt due within 12 months
no data

From the figures the company filed with the SEC. Cash flow over net income near or above 1 means earnings are collected in cash; far below, that part is accounting. Coverage says how many times operating income pays the latest fiscal year's interest. Maturities come from the debt note of the latest annual report, counted from its closing date. “No data” never means zero.

Above 5% (13D/13G)

Disclosed stakes, with their amendments. A filing is not always a purchase: there are also reductions and changes of filing entity.

This list may be incomplete: we hold 13D and 13G filings made since Dec 23, 2024. A holder above 5% that has not filed anything since then is not shown here.

Above 5% over time (13D/13G)

Each holder with its filings in order. History since December 2024.

This company filed no 8-K forms in the last year. Foreign companies listed in the US (ADRs) report material events on forms 6-K and 20-F, and ETFs and funds do not file 8-Ks. If it is a foreign company listed in the US through ADRs (American Depositary Receipts), what trades are bank-issued certificates that represent shares from its home market.
