The most likely reasons a statement may not be concise are unnecessary qualifiers, redundant pairs of words, and wordy sentences.

Explanation: There are many reasons why a text can be unconcise. One of the most common ones is the use of unnecessary qualifiers, such as "definitely", "really" or "undoubtedly", since they add a redundant and informal meaning to the sentence.
