The firm's scale is such that with the right revranding,it could bounce back.

网友说的不错，such 可以直接用作形容词作表语，也可用作先行限定词，修饰名词。例如： such a degree。

网友的句子，that从句为“结果状语从句”；The firm's scale is such 为主句，主句可以变成：The firm is on such a scale that...

又如：

The project is on such a gigantic scale that the cost is hard to calculate. 

工程浩大， 所费不赀。
