Nexus Infrastructure plc provided earnings guidance for the six months ended 31 March 2018. For the six months ended 31 March 2018, Nexus expects to have achieved Group revenue and operating profit ahead of the performance in first half of 2017. The Group continued to secure work in the period and the order book as at 31 March 2018 was £234.1 million, a year-on-year increase of 30% and a £31.4 million increase (16%) in the first half of the financial year. The Tamdown order book increased to £118.4 million (18% year on year) and the TriConnex order book increased to £115.7 million (44% year on year). During the period under review, Tamdown performed in line with the Board's expectations and is expected to report first half of 2018 operating profit ahead of first half of 2017. TriConnex performed broadly in line with the Board's expectations and is expected to report an first half of 2018 operating profit marginally ahead of first half of 2017. The Board expects the outturn for Tamdown's operating profit for 2018 to be in line with its expectations and ahead of 2017. However, although TriConnex has secured a 44% increase in order book, it is expecting revenues and operating profit for 2018 to be in line with 2017, which is below the Board's previous expectations. The company expects the order book at the end of 2018 to continue to grow further based on the current pipeline opportunities.
