SINGAPORE - The following companies saw new developments which may affect trading of their shares on Tuesday (Jan 23):

AEM Holdings: The company said on Monday that it expects its operating profit before tax for the 2017 financial year to reach between S$35 million and S$37 million, up from a previous guidance of at least S$32 million. The group's 2017 revenue guidance of at least S$215 million remains unchanged. On Dec 21 last year, AEM announced that it had received sales orders worth S$100 million for delivery for the first half of 2018.

Frasers Commercial Trust (FCOT): FCOT has posted a first-quarter distribution per unit of 2.4 Singapore cents, down 4.4 per cent from 2.51 Singapore cents in the same period a year earlier as property income fell while the number of issued units had increased. Gross revenue for the first quarter ended Dec 31, 2017 dipped 11 per cent to S$35.3 million from the same period a year earlier.

Lum Chang: Its Lum Chang Building Contractors unit has won a tender for the construction of PSA Singapore's corporate headquarters. The contract, valued at S$136.9 million, will involve building a new 20-storey Class A office tower and an adjacent four-storey block with recreational amenities, as well as addition and alteration works at the existing Pasir Panjang Terminal Building 3.

Keppel Infrastructure Trust: It reported a distribution per unit of 0.93 Singapore cent for the fourth quarter, unchanged from the year-ago period, on Monday. Profit attributable to unitholders rose by 25.4 per cent to S$9.6 million for the quarter, due mainly to higher contributions from City Gas. Revenue for the quarter came up to S$158.1 million, nearly 4 per cent higher than the S$152.2 million last year.
