Significant mergers and acquisitions have littered the financial landscape over the years. Some include popular and well-known companies like when AT&T merged with Time Warner or Disney, and Marvel joined forces. Lesser-known companies that make the most significant impact with little to no publicity. According to, the US has already seen $1.8 trillion in mergers and acquisitions in 2021, expecting the number to increase by the end of the year. Here are the five biggest mergers of 2021 so far.

TD Synnex

When Tech Data merged with Synnex to become TD Synnex, the new company pushed Ingram Micro out of the top spot as the world’s largest IT company. As information technology generally takes a larger role in economies both in the US and across the world, this is a big deal. Analysts believe that the new company will see noticeable stock growth in the next 12 months due to its stake in cloud technology, cybersecurity, and big data analytics, to name a few. 

Canadian Pacific

In March, Canadian Pacific acquired Kansas City Southern for $29 billion. The railroad industry has been around for centuries, and it is just as relevant now as ever. Railroads are lucrative because of travel and freight and cargo transport, which has become even more important of late. When the deal is completed and KCS goes away, the new stock is expected to do well in the short and long term.

Roger Communications

Canada’s two largest communications companies saw Rogers Communications purchase Shaw Communications for $26 billion. The move saw Rogers take on $6 billion of Shaw debt and is expected to increase significantly the speed and coverage of a 5g rollout countrywide.

Aercap Holdings

Aercap Holdings acquired 100% of GE Capital Aviation Service capital for a reported $24 billion. This will form one of the largest aircraft lessors globally and will allow GE, the parent company of the GE Capital Aviation Service, to reduce its debt by $30 billion. This deal is expected to strengthen both companies in the long run, with GE Aviation Service no longer existing when the deal is completed. 


There was an all-stock deal between Cimarex and Cabot Oil and Gas that left Cimarex with 50.5% of the stocks and Cabot with 49.5%. This deal brings together Cimarex’s acres in West Texas with Cabot’s shale positions in the North East as other gas companies that have joined together have had overlapping geographical areas.
