ASML just reported their Q1-17 results:
"A positive industry environment provided a strong start to 2017 and healthy demand is expected to continue throughout the rest of the year. Our DUV business saw strong demand from all sectors of the industry. Our service and options business was also very strong in the first quarter, as a number of customers bought performance-enhancing upgrades for their existing immersion tools. Our second-quarter guidance shows that we expect these trends continue," ASML President and Chief Executive Officer Peter Wennink said.
"In EUV, which is now in a phase of industrialization, the order flow continued, taking our backlog to 21 EUV systems."
Besides the 21 EUV systems in present backlog they also reported 4 (field) upgrades of 3300/3350 to 3400. So, customers are also upgrading their present EUV (development) tools to the latest 3400 (HVM-production) version.
CFO Nickl stated in the video message that they expect to sell/ship about 20 units of the 3400 EUV tool in 2018. Also they expect memory to be stronger in 2017 than 2016.
All in all it seems ASML is reporting solid sales:
