Not exactly a structure, but in an industry wide profitability issue, there are a number of typical potential "answers" which you should explore and use your structure to narrow down / verify.
- Focusing on a segment: Overall industry may be declining, but a specific segment of it may be growing - for example, the overall "soft drinks" market might be shrinking, but health drinks in specifically is a growing market.
- Move into new, high growth industries/markets: if margins are under pressure in your home market (e.g. due to regulation, competition), you may look to expand into different industries/markets - either starting operations in a different geography, or "pivoting" into a related industry (with higher growth/margins).
- Put pressure on costs: If margins are tight industry wide, firms often end up having to compete on costs to survive - so answer is often a cost based one
- close up shop: this is always an option to remember, especially in a case where you might be looking only at a subsidiary of a larger parent firm. If you find there's no realistic way to fix profitability issues (assuming profits are negative), the best course of action may be to liquidate.
This is not necessarily an exhaustive list, and none are things you should recommend off the bat - rather, they are areas to explore further to determine if they are feasible.
Hope this helps!
