M&A in the technology world are probably at an all-time high in the first half of 2016.It\u2019s not only technology companies acquiring competitors or complementing companies to boost their product portfolio and market share\u2014private equity (PE) firms are now investing heavily in enterprise technology brands.\u00a0\u00a0The Polycom buy-out reached an interesting turnaround as the video conferencing equipment maker surpassed Canada-based Mitel\u2019s offer announced three months ago. Polycom last week decided to go the private route with PE firm Siris Capital.Must Read: Polycom accepts Siris Capital's $2B offer, cancels Mitel mergerAt least half a dozen prominent enterprise IT companies\u2014Epicor, Qlik, SonicWALL, Lexmark, Quest Software and Polycom\u2014in the past four months have not been acquired by other technology OEMs. They have been invested into by PE firms and global investment firms.\u00a0While tech companies buying other tech companies is the norm, there are also non-tech companies getting into the IT fray this year. For example, IT distribution giant Ingram Micro was acquired by Tianjin Tianhai, a Chinese shipping group for $6B. There was also the colossal $32B buyout of chip maker ARM by SoftBank.Tech, non-tech, PEs and banks \u2013 all want a big bite of the fast-growing IT business.Change of management during acquisitions is often challenging for the company employees, business partners and client base on both sides of the fence. The integration of work culture, change of management, new GTM and other factors influence the success ratio too.However, investment by global investment companies or PE firms does not bring legacy (of people, processes and products) as in the case of one tech company buying another. But the challenge of retuning the business strategy of the acquired technology company still looms large.History beckonsSince 2013, the IT industry has witnessed a slew of private investments in technology companies like Informatica (April 2015), Blue Coat (2012 and then 2015), Riverbed (December 2014) and BMC Software (May 2013).Read: Blue Coat Systems gets flipped for $2.4 billionWebsense got acquired for $906M in a private equity deal lead by Vista Equity Partners in May 2013.
