Oceana Group Limited provided earnings guidance for the six months ended 31 March 2018. Basic earnings per share (EPS) for the six months ended 31 March 2018 compared to the six months ended 31 March 2017 (comparative period) are expected to increase between 55% and 65%, to between 300.7 cents per share and 320.1 cents per share (six months ended 31 March 2017 value is 194.0 cents per share). Basic headline earnings per share (HEPS) for the six months ended 31 March 2018 are expected to increase between 55% and 65%, to between 300.4 cents per share and 319.8 cents per share (six months ended 31 March 2017 value is 193.8 cents per share) compared to the comparative period. The increase in EPS and HEPS is largely attributable to the release of USD 13 million deferred taxation in Daybrook following the reduction in the federal corporate tax rate in the United States of America from 35% to 21%. The group's operating profit before associate and joint venture income and fair value adjustments is expected to increase between 5% and 12%. This increase is largely attributable to improvements in the canned fish and the horse mackerel and hake segments which were offset by a decline in USA fishmeal and fish oil earnings.
