Oxford Instruments PLC (AIM:OXIG) improved 6% as the tech group forecast a recovery this year backed by an order book worth £302 million.
Sales in the year to March rose by 9.8% at constant currencies, though underlying profits were flat at £80.3 million as it limited sales to China.
OIG added it intends to split its operations into two new divisions – Imaging and Analysis and Advanced Technologies - to simplify its operations.
Revenue will be split 70/30 between the two divisions, with its Imaging and Analysis products likely to see the highest sales.
The group also agreed to acquire FemtoTools, a Swiss developer of nanoindentation instruments for an initial Sf17 million (£19.4 million).
Shares rose 155p to 2,615p marking a 26% rise in the past three weeks.
