Business Outlook
(Discussion on an IAS 18, non-IFRS basis, with revenue growth rates in constant currencies)

Pascal Daloz, Dassault Systèmes’ Executive Vice President, CFO and Corporate Strategy Officer, commented, “Building on the strong start to 2018 in the first quarter, our second quarter financial results were aligned well with our objectives, bringing us to a solid first half performance, with software revenue up 9%, 160 basis points of underlying organic operating margin improvement absorbing both currency headwinds and acquisition dilution, and earnings per share up 13% as reported and 23% at constant currency. Cash flow from operations was also strong, increasing 9% in the first half to €645 million.

“Looking to the full year outlook, we are now targeting IAS 18 non-IFRS total revenue growth of about 9% to 10% in constant currencies, confirming acceleration in 3DEXPERIENCE activity as our first half results demonstrated, and healthy software growth for SOLIDWORKS for the year in total while anticipating a high base of comparison in the third quarter. We are then updating our financial objectives for new acquisitions. Our new revenue range is €3.41 to €3.44 billion, incorporating the second quarter currency upside.

“In turn, we are upgrading our EPS objective, targeting IAS 18 non-IFRS earnings per share of €2.95 to €3.00, representing growth of about 10% to 12%, reflecting higher activity, currency and improved effective tax rate for the year. At constant currency, this would represent a growth rate of about 15% to 17%.”
