(Reuters) - Global mergers and acquisition (M&A) activity hit a record high for the third straight month in May, driven mainly by low interest rates, soaring equities and higher dealmaking interest in sectors that have received a boost from the COVID-19 pandemic. According to Refinitiv data, the total value of pending and completed deals announced from the January-May period touched$2.4 trillion, an all-time record. Last month, $532.9 billion worth of deals were recorded, the highest for the month of May.

The surge in deals comes as more companies look to deploy massive war-chests as they focus on expanding their businesses, and as major economies across the world are resuming normal business after ramping up vaccination efforts. The United States witnessed $1.3 trillion worth of M&A activity this year, while Europe and the Asia-Pacific saw $411 billion and $387 billion, respectively.

Analysts also said the world’s biggest private equity firms have raised large amounts of capital over the past few years, which has contributed to the surge in M&A activity. The merger between AT&T’s Warner Media and Discovery, home to lifestyle TV networks such as HGTV and TLC, is the biggest deal of the year so far, with the enterprise value of the new combined company standing at more than $120 billion.

Industrials M&A volumes stood at $255.1 billion, while financial services accounted for $250 billion. Acquisitions by blank-check companies or SPACs (special-purpose acquisition companies) also hit a record $348 billion in the January-May period.

Blake Hutchison, CEO at Flippa.com, said he expects M&A activity to continue to be strong for the rest of the year. “There’s no evidence of a sensational shift in market conditions in the near term. I sense that M&A activity will thrive in food & beverage and eRetail with consolidation,” he said. “For other industries, the surge to an online economy will force the hand of many. They’ll see no other way but to acquire innovation as they’ll need to leverage data and analytics found in digital players and their platforms / ecosystems.” Reporting By Patturaja Murugaboopathy, Editing by Anirban Sen and Kim Coghill Our Standards: The Thomson Reuters Trust Principles.
