Pass-through vehicle. This looks like a holding, staffing or umbrella company. Its revenue and profit may largely pass through to or from other entities, so the figures may not reflect a standalone operating business. It is excluded from our opportunity lists.

Part of a group. The filing indicates this company sits within a group structure, so its results may depend on intra-group trading and it may be hard to replicate independently. From the filing: “Globemile Limited”

Unusual figures. Profit is higher than revenue in this filing. That usually means investment income, dividends from subsidiaries or one-off gains — or a mis-tagged figure. Check the original filing before drawing conclusions.
