(Telecompaper) Akamai Technologies and Prolexic Technologies have announced the two companies have signed a definitive agreement for Akamai to acquire Prolexic, provider of cloud-based security services. With this acquisition, Akamai plans to offer customers a portfolio of security services that defends an enterprise's web and IP infrastructure against application-layer, network-layer and data centre attacks delivered via the internet. Under the terms of the agreement, Akamai will acquire all of the outstanding equity of Prolexic in exchange for a net cash payment of approximately USD 370 million, after expected purchase price adjustments, plus the assumption of outstanding invested options to purchase Prolexic stock. The closing of the transaction, subject to customary closing conditions, including regulatory approvals, is expected to occur in the first half of 2014. The Prolexic acquisition does not affect Akamai's Q4 guidance but is expected to be slightly dilutive to Akamai's non-GAAP net income per share in the first year post closure in the range of USD 0.06-0.08. Once the acquisition closes, the company will include Prolexic in its guidance going forward.
