Ocean Sky International

What Ocean Sky International does

Ocean Sky International Limited is a Singapore-incorporated investment holding company listed on the SGX Catalist board (ticker: OSIL, SGX:1B6) that operates two core business segments — Construction & Engineering and Property Development & Investment — with operations spanning Singapore, Cambodia, and Australia. The Construction & Engineering business is conducted through wholly-owned subsidiary Ang Tong Seng Brothers Enterprises Pte Ltd (ATS), which has been operating since 1981 and provides civil engineering services including earthwork, roadwork, drainage, basement work, structural works involving demolition and underground infrastructure, and general building works; ATS is registered with the Building and Construction Authority of Singapore under Grade B1 for Civil Engineering and Grade C3 for General Building. Equipment wholesale and leasing is handled by a separate wholly-owned subsidiary, Ang Tong Seng Construction Pte Ltd (ATSC), established in 2018.

The Property Development & Investment business combines luxury Singapore residential development via a 40%-owned joint venture (TSky Development Pte. Ltd.) with Tiong Seng Holdings — which has delivered Sloane Residences in District 10 (TOP November 2022) and Cairnhill 16 in District 9 (TOP April 2024) — with international exposure including a 71-unit shophouse development (Eco Garden Mall) in Kandal Province, Cambodia and a freehold four-storey office building at 541 Blackburn Road in Melbourne's Monash Technology Precinct that provides recurring rental income. Construction revenue is earned via direct bidding on government and enterprise contracts in Singapore; property revenue is earned on a project-completion (sale) basis for developed units and on a recurring rental basis for the Melbourne office.

The company is controlled and led by Executive Chairman and CEO Mr Ang Boon Cheow Edward, who has been associated with the group since 1992 and oversaw the 2016 consolidation of ATSB as a wholly-owned subsidiary and the 2013 diversification into property development. The board includes three independent directors with substantial real estate and financial credentials (former GuocoLand Group President/CEO, a tax principal at PricewaterhouseCoopers, and a senior architect/developer). Distribution is exclusively through direct sales and project-specific marketing, with the corporate website and SGX investor relations portal serving as the primary communication channels.
