StrengthThe unit economics reproduce the projections exactly, in every year

Multiplying the stated channel volumes by the stated per-litre figures reproduces the projected revenue, cost of goods and gross profit to within rounding in all five years, Year-5 revenue of R195.2 million, for example, is exactly 18.0 million litres at R3.80 plus 10.5 million at R7.00 plus 2.6 million at R20.50. This is a higher standard of internal consistency than most plans of this kind achieve, and it means an investor can test any scenario simply by changing volumes or prices in the unit table and reading the consequence directly. It also means the unit economics are the model: if the per-litre assumptions hold, the projections hold.

Figure 7. Premium glass cost structure per litre.

Analyst flagGlass packaging is 27% of the FOB price and is the concentrated cost exposure

At R5.60 a litre against a R20.50 FOB price, primary packaging alone is over a quarter of the premium line’s revenue, and the Plan’s own SWOT identifies premium glass packaging as a significant and import-linked cost. The risk register rates PET resin and glass price inflation as high likelihood. That combination deserves attention: a 20% increase in glass cost reduces Year-5 EBITDA from R39.1 million to R36.2 million on current volumes, which is absorbable, but the exposure scales directly with the export ambition. Sourcing glass domestically, as the sustainability section commits to, is the correct mitigation and should be evidenced with a supply agreement rather than an intention.

4.3 The mix shift is the strategy

Figure 8. Group gross margin rises through mix, not price.

Group gross margin rises from 43.9% to 49.2% almost entirely through channel mix rather than price increases. Every unit price in the model is held flat across the five years, so the improvement is arithmetic: as the higher-margin export channels grow from nothing to 65% of revenue, the blended margin follows. That is a more credible margin story than one built on assumed price increases, and it is testable, if the export volumes arrive, the margin arrives with them.
