Key strategic wins secured in 2017 demonstrated traction in our key focus areas: active test and assurance in operational networks and in cyber security.

The demand for high-speed Ethernet, particularly in 400G, is expected to rebound later this year.

We expect that our 2018 results will once again be weighted to the second half, owing to our normal seasonality, but amplified by two additional factors.

The first is the expected rebound in Ethernet testing in the second half and the second is the expectation that Lifecycle Service Assurance spending is likely to be second half weighted after the heavy spending flourish at the end of 2017.

The stronger growth anticipated in our areas of strategic focus is expected to drive the performance of Spirent again in 2018.

The Board is confident that the group will show progress in 2018 while continuing to focus on a balanced approach to operational efficiency and investment in product development in its core growth businesses.
