Dr Asah-Asante said Mahama's experience as former president held him in good stead to navigate Ghana through choppy waters.
"Of course, he is likely to encounter difficulties, but he has what it takes to turn things around," the analyst added.
Mahama's previous stint in government - as vice-president and president - was plagued by corruption allegations, but he has consistently denied any wrongdoing.
In 2020, a UK court had found that aviation giant Airbus had used bribes to secure contracts with Ghana for military planes between 2009 and 2015.
An investigation then got under way in Ghana, but the Office of the Special Prosecutor, in a decision announced just months before the election, concluded there was no evidence that Mahama was involved in any corrupt activities himself.
