Can you be more specific please? Growth of what?
Answer if it is sales growth:
You can start from the equation: EBITDA = Revenues - COGS - SG&A
If the revenues went up but EBITDA went down it means that COGS or/and SG&A went up not linearly
You can start from this equation to find ideas.
I think about:
- Increase of per-unit cost (diseconomies of scale or inflation or suppliers increased their prices)
- Large spending on sales operations to sell more (hiring more employees, advertising, increase of wages due to a new regulation)
