But Pilkington said it was well placed to cope with current market conditions, but its shares edged down in morning trade, as the second half outlook led investment bank Merrill Lynch to trim its forecast for annual profits.
Pilkington was trading down 1.9 percent at 103 pence by 0950 GMT. The stock has underperformed the FTSE construction and building materials sector by about 10 percent since the start of 2001.
Merrill analyst Kevin Cammack said he would probably cut his current annual pre-tax profit forecast of 245 million pounds by five percent. He kept an "accumulate" rating on the stock, with a price target of 120 pence.
Leading Pilkington institutional shareholder Active Value Capital said that while they were pleased with the results and the company's management, they felt Pilkington should buy back shares to give a boost to the stock price.
"We've been in regular correspondence with the company, and they've said a share buyback is something they would consider," Active Value fund manager Julian Treger told Reuters. Active Value owns around four percent of Pilkington.
