There are probably 3 main areas that could be influencing this.
1) Cost increases that directly led to this sales growth (i.e. new factories, increased sales team, larger marketing bucket etc.)
2) Pricing changes that drove sales. I.e we charge less for a product, earn much lower margins, drive volumes up, but lose money.
3) Product mix - we are selling a lot more of a low-margin product
I also note that you've posted a lot of questions recently. Have you considered coaching? 1-off Q&As are not the best approach to building full knowledge of the business world + casing!
