Highveld Detailing Business Plan — Cost Structure and Operating Leverage

Why gross margin falls while EBITDA margin rises, and where the operating leverage actually sits.

Cost Structure and Operating Leverage

Jump to section

Direct labour is 37% of revenue at maturity and cannot be reduced without reducing volume. That single fact caps the achievable EBITDA margin in the low teens and makes the business far more sensitive to throughput than a conventional services model would be.

Fixed versus variable

For break-even purposes the model treats direct labour as 45% fixed, reflecting the establishment floor of 60% and the practical impossibility of reducing a trained embedded team in response to a month of low vehicle flow. On that basis the FY2032 contribution margin is 60.9% and the fixed cost base is R44.0m.

The treatment of labour as partly fixed is the single most important judgement in the break-even and downside analysis. A more optimistic treatment, assuming labour flexes fully with volume, would produce a materially more attractive downside case and would be, in the view taken here, unrealistic.
