_The outside date is a date where both parties have agreed in advance that if the merger or acquisition has not yet completed either side can terminate the merger agreement and walk away from the deal free of any penalties. However, it is often stipulated that if certain duties were not performed by a given party prior to the Effective Time, the act of termination under this clause will not be available.
The actual significance of the date is not as final as it may suggest. The date is neither the forecast completion date, the expected completion date, nor even the latest completion date. It is in rare circumstances such as Qualcom’s (QCOM) bid for NXP Semicondctor (NXPI), that one the parties invoke this clause and walks away, although in QCOM’s case, a reverse termination fee was paid. Having not received clearance from SAMR, QCOM decided the time had come to terminate. Therefore, both parties may agree to extend, if for example more time is required to complete an ongoing regulatory review such as a second request for information under HSR, which is likely to produce a positive outcome._
"outside date" for the deal is May 26, 2023. EU said they will finish June 7. So it doesn't mean much really. VMW and BC can agree to extend if the EU regulatory stuff isn't completed. And they likely will. Or maybe they are trying to push the EU to finish two weeks early. Either way, this extension doesn't seem like much of anything to get excited about.
