In comparison to 2015, which saw M&A hit levels not seen since 2007, 2016 was a much more challenging year for M&A. The UK referendum caused huge amounts of uncertainty in the first half of the year as dealmakers targeting the UK were reluctant to come to market. This led to a slow-down in M&A activity in the first half of the year with 3,110 deals worth US $342.8bn; both the lowest H1 value since 2013. The vote itself caused shockwaves in the market, reducing activity further as many dealmakers looked to postpone or cancel proposed deals in order to wait for some of the immediate turmoil to settle down. Moving into the last part of the year however, deal activity has rebounded as with the decision now known, dealmakers looked to make up for lost time.
