Net profits at aircraft maintenance firm SIA Engineering slid 20.2 per cent to $35.5 million for the second quarter ended Sept 30.
Earnings for the same three months last year were boosted by gains from associated firms.
At the operating level, profits fell by 9.3 per cent to $24.5 million.
Revenues dipped 0.5 per cent to $264.8 million while expenditure rose 0.5 per cent to $240.3 million.
This was mainly due to increases in material and staff costs, which were offset in part by lower subcontract costs, the firm said.
For the first half, net profits soared more than 172 per cent to $233.9 million, on the back of gains from the divestment of associates.
