Speaking earlier about progress towards the merger   Essilorâs Chief Operating Officer Laurent Vacherot  said: âWe are serene â repeating that the deal was expected to close in the first half of 2018.
Announcing its annual results   Essilor  said  it  was targeting revenue growth of around 4 percent in 2018. Revenues rose 3.1 percent on a like-for-like basis to 7.5 billion euros last year  partly helped by higher sales in North America.
A measure of profitability stripping out the cost of sales and operating expenses stood at 18.2 percent of revenue in 2017  down from 18.6 in 2016 and is forecast at a minimum of 18.3 percent in 2018.  The company  gave few further details.
 Vacherot  said Essilor would keep pursuing  its  strategy of bolt-on acquisitions in 2018  particularly in China and India.
