Generally, you would say impressive or handsome profits. It all depends on the context. Hope this helps, Thanh! :)

Depends on the context or idea you are trying to get across. If it is a post about making money. It could go like this. Huge profits, impressive returns on your investment. Also could say: Attractive profits with handsome returns on your investment.

You can use all. It just depends on your writing style or the way you like to describe things. You can also say they profited handsomely…

oh the full sentence is : the company has made ......... profits thanks to its new financial policy.

If you are talking about making profit, you can say it is a impressive amount of money or you can say i received an attractive offer for a new job!
