CPPIB, Onex exploring potential $7-billion Tomkins sale: sources Tomkins PLC is exploring a sale that could value the private-equity owned global manufacturer of auto parts and building products at as much as $7-billion, several people familiar with the matter said on Friday. Onex Corp. and the Canada Pension Plan Investment Board (CPPIB), which acquired Tomkins in 2010 for $5-billion (U.S.), including the assumption of debt, are interviewing investment banks to advise them on a sale of the company, the people said. Tomkin's owners may seek to exit the company outright through a sale to another party or float it in the stock market, the people said. A process to explore both possibilities is expected to start in the first quarter of 2014, they added. The people asked not to be identified as the deliberations are private. A Tomkins spokesman said the company does not respond to market rumours. Representatives of Onex and CPPIB did not immediately respond to requests for comment. London-based Tomkins has operations in over 30 countries and sells products ranging from power transmission systems to acrylic bathtubs in over 70 countries, according to its website. It had adjusted 12-month earnings, before, interest, tax, depreciation and amortization of $536-million as of the end of September and net debt of roughly $1.5-billion, according to Onex's third-quarter earnings statement.
