(Reuters) - Cloud communications platform provider Twilio Inc TWLO.N said on Monday it would buy customer data platform Segment for $3.2 billion in an all-stock deal. Twilio’s shares rose more than 9% to $335 in premarket trading. The announcement of the deal, expected to close in the fourth quarter of Twilio’s fiscal 2020, comes after the company estimated third-quarter sales above its previous forecast earlier this month. Cloud companies have seen a surge in demand this year as more businesses use their services to meet the demands of the switch to work from home due to the COVID-19 pandemic. Following the deal, Segment will become a part of Twilio. Morgan Stanley & Co LLC was Twilio’s financial adviser, while Cooley LLP was its legal adviser. Qatalyst Partners was Segment’s financial adviser and Goodwin Procter LLP acted as its legal adviser.
