Definitely I don't have any real insight into IBanking but as I understand there's usually IBanking M&A division whose activity (and corresponding compensation) generally revolves around two activities - generating pitch books to generate transactions and then generating transactions. I imagine for IBankers there's only incentives to generate transactions regardless of whether they are good or bad for the two parties actually involved in the M&A transaction. I'm not aware there's any activity/compensation tied to the long term (i.e. 10 year ROI) success of deals.

It'd be smart if internal M&A divisions were held to higher standards - not only being measured on number of pitch books generated and transactions closed but also additional OKRs/compensation regarding the long term success of previous transactions for the company.
