In the year-over-year percentages, it appears that the decline in income is due to the decline in profit-margin because revenue actually went up.
So reach for an overall viewpoint.
In fact, semi-conductor manufacturers often feature gross-margins because they have naturally high margins and because they have manufacturing yield results. But gross-margins could be largely forgotten if there are severe drops in revenue. Other industries will feature different defining fundamentals.
Finally, income alone doesn't identify what is happening with the company. Revenue combined with profit-margin gives a more complete view.
The best hope for predicting the future is a statistical curve-fit of the past. Otherwise there is a list of fundamentals as declining, holding, or increasing.
