Hyflux

Hyflux was a Singaporean water-treatment and environmental-solutions company founded by Olivia Lum in 1989. It began as Hydrochem (S) Pte Ltd with three employees and modest start-up capital, supplying water-treatment systems. Over time, it developed into a vertically integrated provider of water, wastewater, membrane and desalination technologies, serving municipal, industrial and infrastructure customers in Singapore and overseas markets. The company’s growth was closely associated with membrane-based treatment and large public-private infrastructure projects. It became one of Singapore’s earliest listed water-treatment companies when it joined SESDAQ in January 2001 and later moved to the Singapore Exchange Mainboard in April 2003. Hyflux received international recognition in 2006 when Global Water Intelligence named it Water Company of the Year. Its business expanded beyond equipment supply into the development, financing and operation of major water facilities. The Tuaspring Integrated Water and Power Plant became the company’s most important and ultimately most damaging project. Hyflux won the tender in 2011 to develop Singapore’s second and largest desalination facility after submitting a highly competitive water-supply bid. The desalination plant began operating in 2013, while the associated power plant started operations in 2015 and began commercial electricity sales in 2016. To support the project and other growth initiatives, Hyflux used substantial debt and issued preference shares and perpetual securities to investors. Although the group reported strong profits earlier in its history, its financial performance weakened as the power-generation component of Tuaspring faced difficult electricity-market conditions and the overall project generated losses. The company suspended trading in its shares in May 2018 and sought court protection while attempting to reorganize its liabilities and operations. A proposed investment by the Salim and Medco groups did not ultimately resolve the company’s financial problems. Retail investors publicly opposed aspects of the restructuring proposals, particularly the treatment of preference shares and perpetual securities. In 2019, Singapore’s Public Utilities Board issued a default notice relating to Tuaspring and subsequently took over the desalination plant for no consideration, stating that the facility’s valuation was negative and that Hyflux’s contractual and financial defaults had impaired the project. Maybank, the principal secured creditor, took steps concerning the power plant. These developments left Hyflux without a viable path to restore its former operating model. The Singapore courts placed the company under judicial management in November 2020 because of excessive debts. Hamish Alexander Christie and Patrick Bance of Borrelli Walsh were appointed as judicial managers. After negotiations with a potential investor failed, the judicial managers applied to wind up the company in June 2021. The High Court approved the winding-up on 21 July 2021, converting the judicial managers into liquidators. Subsequent criminal and regulatory proceedings involved former senior officers and directors over alleged breaches of Singapore securities and companies legislation. Hyflux therefore moved from being a prominent Singapore water-technology company to a liquidated corporate estate.

Hyflux began in Singapore in 1989 as Hydrochem (S) Pte Ltd, founded by Olivia Lum with three employees and start-up capital of S$20,000. Its initial business was the sale of water-treatment systems. The company gradually expanded from equipment supply into engineering, membrane technology, desalination and the development of large-scale water infrastructure. The group’s first major capital-markets milestone came in January 2001, when it became the first water-treatment company to list on Singapore’s SESDAQ market. It transferred to the Singapore Exchange Mainboard in April 2003. Listing gave Hyflux access to capital for research, international expansion and infrastructure projects. In 2006, Global Water Intelligence, a United Kingdom-based water-sector publication and research organization, named Hyflux Water Company of the Year. Hyflux’s business model combined proprietary and applied membrane technologies with engineering and project-development capabilities. It served municipal authorities, industrial users and infrastructure partners. The company operated in Singapore and pursued projects in China, the Middle East and North Africa. Its activities included desalination, wastewater treatment, water recycling and industrial water systems. The Tuaspring project marked the company’s transition toward large integrated infrastructure. In 2010, Singapore’s Public Utilities Board invited tenders for the country’s second and largest desalination plant. Hyflux submitted a notably low proposed first-year water price and won the tender in April 2011. It established Tuaspring Pte Ltd as a wholly owned subsidiary to develop and operate an integrated desalination and power facility. The desalination plant was completed and began operations in 2013. The power station began operating in August 2015 and started commercial electricity sales in February 2016. The project required significant financing. Hyflux issued preference shares and perpetual securities, including what was described as Singapore’s first non-bank corporate perpetual issue. These instruments attracted substantial investor interest, but the project’s economics deteriorated. Electricity-market conditions weakened, and the integrated facility generated losses. The company’s reported net profit declined from S$59 million in 2008 to S$3.8 million in 2016, although those figures describe historical performance rather than a current financial position. In May 2018, Hyflux suspended trading in its shares and sought court supervision to reorganize its liabilities and businesses. A proposed rescue involving the Salim and Medco groups would have provided new equity in return for a controlling interest, but the proposed restructuring faced strong opposition from retail investors and was not completed. The Tuaspring desalination plant also became the focus of a dispute over performance, valuation and contractual defaults. PUB stated that the plant had repeatedly failed to provide required capacity and later took it over for zero consideration, explaining that its value was negative. Maybank, Hyflux’s largest secured creditor, separately took steps concerning the power plant. The company entered judicial management under a Singapore court order in November 2020. Hamish Alexander Christie and Patrick Bance of Borrelli Walsh were appointed to manage the insolvent business. After efforts to secure an investor failed, they applied for a winding-up order in June 2021. The High Court approved liquidation on 21 July 2021. Following the collapse, Singapore authorities brought criminal proceedings against several former officers and directors concerning alleged securities-law and companies-law breaches. The proceedings included charges against former CEO Olivia Lum and former CFO Cho Wee Peng, an arrest and charge involving former independent director Lee Joo Hai, additional Companies Act charges against Lum, and a guilty plea by former independent director Rajsekar Kuppuswami Mitta. Hyflux’s history illustrates both the growth potential and financing risks of capital-intensive water infrastructure, particularly when a water project is combined with exposure to volatile power markets.
