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.
