Keppel Infrastructure on Monday reported a near 9 percent fall in third-quarter profit.
Keppel Infrastructure said net profit attributable to unitholders fell to S$15.5 million in the three months ended September 30 from S$17 million last year.
Revenue was unchanged at S$160 million.
At City Gas, revenue of S$81.7 million in the quarter was higher
than the corresponding period in the previous financial year, due to higher town gas tariff and higher volume of town gas sold.
"City Gas' performance could fluctuate depending on changes in economic conditions and time lag in the adjustments of gas tariffs in response to changes in fuel costs," the company said.
Revenue from KMC for the third-quarter was stable at S$32.5 million, it said in a regulatory filing.
Operating expenses increased to S$10.9 million in the quarter from S$9.0 million last year due to higher marketing expenses incurred by City Gas and professional fees incurred for the Basslink outage.
Total assets as at 30 September 2017 was S$4,066.0 million, marginally lower than total assets of S$4,118.6 million as at 31 December 2016.
Shares in Keppel Infrastructure ended unchanged at S$0.55 on the Singapore Exchange. The stock has gained about 16 percent so far this year.
