ComfortDelGro Corporation Limited, commonly known as ComfortDelGro, is a multinational transport group based in Singapore. It is listed on the Singapore Exchange and operates more than 54,000 vehicles across 13 countries. It was formed on 29 March 2003 through a merger of Singaporean land transport companies Comfort Group and DelGro Corporation.

History Comfort Group Limited
In May 1970, the National Trades Union Congress (NTUC) announced plans to provide a cooperative taxi and minibus service. The cooperative was aimed to target the problem of pirate or "ali baba" taxis which were rampant in Singapore at that time, and NTUC planned to get former pirate taxi drivers to drive the minibuses as part of the cooperative. The NTUC Co-operative Commonwealth for Transport Limited ("COMFORT" or "NTUC Comfort") was hence formed by the NTUC as a social enterprise together with the affiliated NTUC Income and NTUC Welcome. Comfort started operations in 1971 with a fleet of 1,000 taxis, with the first taxis entering service at the end of January that year.
In June 1993, NTUC Comfort was corporatised and renamed Comfort Transportation Pte Ltd. Comfort was subsequently listed on 6 June 1994 and became the Comfort Group Limited. The listed company was owned by Singapore Labour Foundation (41.7%), its owner-drivers as a single block (approximately 20%) and the public (35%).
At the time of the merger announcement in 2002, Comfort's taxi business operated under the brand names of Comfort and Yellow Top with a combined fleet of approximately 11,340 taxis. It was Singapore's largest private bus operator then with 401 buses on unscheduled routes. It also had a fleet of 730 taxis in China through joint ventures.
DelGro Corporation Limited
Singapore Bus Services Limited was established on 1 July 1973 to unify bus services in Singapore. The company was replaced by Singapore Bus Service (1978) Limited on 17 February 1978, which was then listed on the Stock Exchange of Singapore (SES) on 26 June the same year.
By the 1990s, the company has diversified to other land transport businesses such as taxis, as well as property and engineering businesses. In 1992, the bus operations were reorganised under a new subsidiary SBS Bus Services Pte Ltd. The original parent company Singapore Bus Service (1978) Limited was renamed DelGro Corporation Limited on 12 November 1997, from the words "Delta" and "Growth". On 10 December the same year, the bus subsidiary SBS Bus Services Pte Ltd was listed and renamed Singapore Bus Services Limited, before renaming again to SBS Transit in 2001.
Until 1995, SBS/DelGro's taxi operations arm was Singapore Bus Service Taxi Pte Ltd (SBS Taxi Pte Ltd). CityCab was formed in 1995 with the merger of three companies – Singapore Airport Bus Service Ltd (SABS), SBS Taxi and Singapore Commuter Pte Ltd (a subsidiary of ST Automotive).Taxi! Taxi! The Evolution of Singapore’s Taxi-Cabs, Remember Singapore. Retrieved 3 November 2014 CityCab then became DelGro's new taxi operations arm and was jointly owned by DelGro and ST Automotive (later ST Kinetics).
At the time of the merger announcement in 2002, DelGro operated public bus services, taxis and car rental in Singapore, Malaysia, United Kingdom and the People's Republic of China. The Citycab operation ran 5,116 taxis, while SBS Transit was the largest scheduled bus operator in Singapore with 2,872 buses. DelGro had also just been awarded the operation of the North East MRT line and the Sengkang and Punggol light rail systems.
Merger Comfort and DelGro's merger was first proposed on 21 November 2002. In its joint announcement, the merger aimed to "consolidate the transportation businesses of the Companies in order to enhance profitability and shareholder value". The merger was finalised on 29 March 2003.
The merger had a market capitalisation of over $1 billion, combined sales of $1.56 billion, and pre-tax earnings of $196 million. It set to provide a spectrum of transport services ranging from bus and taxi services to leasing and vehicle maintenance and inspections.
The new company's only rival then was SMRT Corporation, which had a market capitalisation of around $930 million, sales of $500 million and pre-tax profits of $88.5 million then. The latter's fleet of some 600 buses and 2,000 taxis was smaller, but it was operating Singapore's rail network entirely.
Expansion into autonomous mobility On 10 December 2025, ComfortDelGro announced its partnership with Pony.ai to begin testing their autonomous vehicle shuttles, branded as Zig Driverless, in the residential district of Punggol, Singapore. This comes after they got approval from Singapore regulators to start autonomous vehicle testing on public roads. Route 2 Lite, a shortened version of Route 2, began operations on 22 June 2026. This was followed by the launch of the full seven-stop Route 2 service on 1 July 2026.
