Reduction in Group's effective tax rate under Patent Box

Victrex plc, an innovative world leader in high performance polymer solutions, today announces that, based on recently-granted UK patents and following discussions with Her Majesty's Revenue & Customs (HMRC) about the UK's Patent Box legislation¹, we now expect our tax rate to be materially lower than previous guidance.

With a strong history of investing in research and development (R&D) and of patenting our Intellectual Property (IP), Victrex's strategy of moving downstream from Polymer to Parts, and further differentiating our business through product leadership, will continue to be supported by our approach to R&D investment, to innovation and IP protection.

Starting in the current financial year ending 30^th September 2017²,  we anticipate the annualised impact of Patent Box to reduce the Group's effective tax rate from approximately 21% to around 12%, with an ongoing favourable impact on earnings per share (EPS) and cash, although no cash benefit would be seen in FY17.

At a trading level, Victrex continues to be comfortable with current expectations.

This announcement contains inside information.

Notes:

1 The UK's Patent Box legislation was introduced in April 2013. The UK government encourages high-value growth in UK plc through a competitive tax regime that supports UK R&D from conception to commercialisation. The Patent Box forms a key part of this strategy by encouraging companies to commercialise their patents and R&D in the UK

2 IFRS requires tax to be recognised on the most likely outcome.  The directors consider the acceptance of Patent Box in the 2017 computations to be more likely than not, although as with all tax items, HMRC reserve the right to query the Company's calculations
