Nuplex said the full benefits of the restructuring would be about $5.6 million a year, with the full benefits reflected in the 2015 year.
"The manufacturing base of Australia and New Zealand is under pressure because of the high currencies and the weak economies," said James Lindsay, equities manager at Tyndall Investment Management. "If they (Nuplex) can consolidate down their plants to other locations then that's probably the best thing to do."
Lindsay said the drop in the shares today may reflect the costs of the restructuring and the impact on profits short term.
The New Zealand dollar is currently at 82.70 US cents, near a six-month high, while the Australian dollar was last at US$1.0436. Shares of Nuplex fell 19 cents to $2.99 on the NZX today and have climbed 39 per cent this year. The shares were rated a 'hold' based on the consensus of six recommendations compiled by Reuters, with a price target of $2.96.
The company hasn't previously given a forecast for 2013 earnings. At its annual results it said earnings before interest, tax, depreciation and amortisation would benefit from the completion of its NuLeap programme, increased capacity in Vietnam of US$500,000 to US$1 million, a full-year contribution from Viverso of at least 12 million euros and from Nuplex Masterbatch of A$5 million.
Net profit in 2012 fell 6 per cent to $62.5 million.
In 2013, per-share earnings would reduce by about 8.6 cents, of which 6.9 cents would be non-cash items. Restructuring would add 1 cent to earnings per share in 2014 and 2 cents in 2015, it said.
