A Boston-based investment firm has agreed to purchase Plano-based Masergy, the company announced Monday. Terms of the deal weren’t disclosed, but Reuters reported the agreement could be for more than $900 million, including debt. Berkshire Partners LLC is purchasing the company from the private equity firm Abry Partners, which is also based in Boston. The deal is expected to close in the next 90 days. Berkshire will be the sole acquirer, according to a release from Masergy. Masergy operates the largest independent software defined platform in the world. The company provides hybrid networking, managed security and cloud communications solutions.

Abry completed its acquisition of the company in 2011. Terms of that deal weren’t released, either.

Masergy CEO Chris MacFarland won Tech Titans’ Corporate CEO of the year award in August for spearheading the company’s quick ascension. Masergy, which ranked No. 26 on this year’s Dallas Business Journal Middle Market 50 list, reported $232.2 million in revenue last year.
