The deal's value includes all of MPS's outstanding shares for $18.00 per share in cash and the assumption of an estimated $873m in net debt.
Subject to a vote by MPS’s shareholders, necessary regulatory approvals and other customary closing conditions, the deal is expected to be completed by the third quarter of the current fiscal year.
