Toronto; April 24, 2015 – IPEX USA LLC announced today the completion of the transaction to acquire

fittings is impressive”, says Alex Mestres, Chairman and CEO of IPEX. “I am passionate about

The synergies between our two companies will provide our customers and the market as a whole
with a broader product offering and increased focus on customer service. I cannot imagine a better
fit.”
