Master's Thesis from the year 2021 in the subject Business economics - Business Management, Corporate Governance, grade: 2,0, FH Vienna, language: English, abstract: Which factors impact the likelihood and extent of employee turnover after M&A transactions?

More recent academic work also backs that statement. Malmendier, Moretti, and Peters (2018) looked at stock performance of winning and losing bidders. They conclude that the entities that lost takeover bids on average outperform the winning bidders by 24 to 37% over the next 3 years.
