Media Release Singapore’s largest industrial district cooling system begins operations to support STMicroelectronics’ decarbonisation strategy Designed, built, owned and operated by a joint venture between SP Group and Daikin Airconditioning (Singapore), the innovative district cooling system will significantly improve the environmental performance of ST’s high-volume semiconductor manufacturing site in Singapore New system expected to reduce carbon emissions by 120,000 tonnes per year, cooling-related electricity costs by 20 percent each year, and repurposing over half a million cubic meters of water consumption per year 21 October 2025, Geneva, Switzerland, and Singapore – STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, and SP Group (SP), a leading utilities group in the Asia Pacific and Singapore’s national grid operator, have commenced operations for Singapore’s largest industrial district cooling system at STMicroelectronics’ (ST) Ang Mo Kio TechnoPark. The event was inaugurated by Ms. Low Yen Ling, Senior Minister of State, Ministry of Trade and Industry and Ministry of Culture, Community and Youth. The system is expected to reduce carbon emissions by up to 120,000 tonnes per year and enable 20 per cent savings on cooling-related electricity consumption. It will also repurpose over half a million cubic meters of water each year by using reject reverse osmosis water, previously used in ST Cooling Towers, to support the new district cooling operations.  This marks ST’s first use of district cooling at a manufacturing facility and will strengthen ST’s commitment to be carbon neutral by 2027. “The deployment of Singapore’s largest industrial district cooling system at our Ang Mo Kio TechnoPark demonstrates our commitment to pioneering energy-efficient solutions that reduce carbon emissions and conserve resources. This achievement strengthens our partnership with Singapore in advancing its national sustainability goals, said Rajita D’Souza, President of Human Resources and Corporate Social Responsibility at STMicroelectronics. “By integrating advanced technologies like the district cooling system, we are driving a smarter, greener future — showcasing how industry leadership and environmental stewardship align to create lasting value for our business, communities, and the planet.” “SP Group’s strategic partnership with STMicroelectronics marks a pivotal milestone in our nation’s transition towards a low-carbon future. This project showcases how collaborative innovation can transform urban infrastructure to deliver sustainable, energy-efficient solutions. District cooling will continue to play a vital role in Singapore’s net-zero ambitions, enabling carbon emissions reduction and enhancing energy resilience across industrial and urban developments,” said Mr Stanley Huang, SP’s Group Chief Executive Officer.  Technical information about the district cooling system  Designed, built, owned, and operated by a joint venture between SP and Daikin Airconditioning (Singapore), the system has an installed capacity of up to 36,000 refrigeration tonnes (RT). It delivers continuous chilled water to cool both manufacturing and office spaces via a centralised closed-loop pipe network replacing individual chillers in each building. The total area served by the system is approximately 90,000 square metres. Chillers in series counterflow configuration reduce the energy required to cool the water. This ensures an efficient and reliable 24/7 operation, with remote monitoring capabilities augmenting the operations team on site to come. “This partnership with SP reflects Daikin’s commitment to delivering advanced, energy-efficient solutions that go beyond immediate operational needs. Our goal is to contribute to a more sustainable built environment, where technology plays a key role in enhancing resilience, reducing environmental impact, and supporting Singapore’s long-term climate ambitions,” said Mr Chua Ban Hong, Managing Director at Daikin Airconditioning (Singapore). Additionally, the new installations free up around 4,000 square metres of space at Ang Mo Kio TechnoPark, which will enable ST to install other equipment contributing to environmental impact mitigation. This includes perfluorocarbon (PFC) abatement equipment, with near-future plans for additional water reclamation systems and volatile organic compounds (VOC) abatement as part of its ongoing sustainability efforts. The project achieved over 2 million accident-free man hours, underscoring the commitment to safety during construction. The district cooling plant has been awarded the Green Mark Platinum Super Low Energy certification by the Building and Construction Authority for its exceptional energy efficiency and sustainable design. Incorporating whole-life carbon assessments during design and construction of the plant also enabled a reduction of about 44 percent in embodied carbon compared to industrial building benchmarks, achieved through optimised material choices and system design to further lower the plant’s carbon footprint. Further collaboration between STMicroelectronics and SP Group To accelerate its decarbonisation roadmap, ST has also partnered with SP to upgrade the cooling system at its Toa Payoh site. Under a 20-year chilled-water-as-a-service agreement, SP will design, build, operate, and maintain a new high-efficiency chiller system, scheduled for completion by December 2025. The system will improve energy efficiency and aims to reduce carbon emissions by approximately 2,140 tonnes annually. In addition to sustainable cooling solutions, ST and SP are implementing a range of sustainable technologies across ST’s Ang Mo Kio and Toa Payoh campuses. This includes the deployment of the energy management information system (EMIS), comprising 2,400 smart electricity meters and multi-utility sensors. With SP’s smart metering infrastructure in place, ST can monitor its overall energy consumption – enabling data-driven decisions that enhance efficiency and sustainability. SP has also implemented smart water meters that track water inflow to five of ST’s buildings. This provides ST with an accurate view of its water consumption, allowing the organisation to enhance its critical wafer fabrication operations by ensuring greater water efficiency. Together, the partnership delivers on a shared vision for a smarter, cleaner energy future through integrated digitalisation and decarbonisation at scale.

Media Release SP Group donates $850,000 for preventive outreach to isolated youths, run by Youth Guidance Outreach Services Cyber Outreach initiative aims to prevent them from becoming “hidden youth”. SINGAPORE, 5 DECEMBER 2025 – SP Group (SP) is donating S$850,000 to Youth Guidance Outreach Services (YGOS), to support its Cyber Outreach initiative, providing rehabilitation and prevention programmes for youths who may be addicted to online gaming and face the risk of social isolation. Through early intervention, the initiative aims to prevent them from becoming “hidden youth” – individuals who are disconnected from school, family, and the community and isolate themselves at home. This builds on SP Group’s past contributions to YGOS’ outreach programmes, bringing its total contributions to S$1.6 million. The initiative was launched today by Mr Xie Yao Quan, Advisor for Jurong Central GROs. Mr Xie witnessed the presentation of SP’s donation to YGOS, which was made through Community Chest. Extensive social isolation among youths can lead to poor physical health, strained family relationships, increased risks of psychological issues and even suicidal behaviours[1]. According to the Ministry of Manpower’s 2024 Labour Force Survey[2], around 17,000 youth, aged 15 to 24, in Singapore were not in school, employed nor undergoing any form of training in 2023. This represents 4.1 per cent of youth in Singapore who may be at risk of becoming “hidden youth”. This year, the government reaffirmed its commitment to preserve social mobility and strengthen safety nets – building a nation that prioritises youths and future generations. In his first parliamentary address as Prime Minister, Lawrence Wong[3] cited growing concerns among young people on intensified competition and social stratification, highlighting similar global trends such as "躺平 (tang ping)" in China, "hikikomori" in Japan and "quiet quitting" in the West. He emphasised Singapore’s commitment to defy these trends. Mr Xie said, “The world our youth face today is changing faster than ever – shaped by technology, global challenges, and evolving social norms. As a community, we must respond with understanding and action by creating safe spaces, strengthening family bonds, and offering various pathways for learning and growth. Together, we can help young Singaporeans feel valued and supported in building their future.” Mr Stanley Huang, Group CEO of SP Group, added, "Our youth today are the foundation and future talent pipeline for our nation’s growth and development. We are committed to empowering them with the right support and resources to thrive in an increasingly complex digital world. By effectively engaging them where they are, we can connect with them in ways that resonate with their interests, and foster a sense of self-worth and belonging. This in turn can help build their confidence, hone their social skills and prepare them for a smooth transition into young adulthood.” “We believe that early intervention is critical in supporting youths before challenges escalate. With the launch of our Cyber Outreach, a dedicated team to run the programme, and through our ongoing initiatives, we aim to extend sphere of connections and mentoring efforts. These will help us go further in creating a stronger and more supportive ecosystem – where every youth feels safe, seen, and empowered to do their best”, said Wilson Tan, Executive Director of YGOS. One of the youths who has benefitted from the intervention programme is 14-year-old Joey Chung. Joey was constantly immersed in online activities as she felt unseen and unheard. Before joining YGOS, she often hid behind the screen – a common behaviour among hidden youths who turn to gaming or online spaces to feel safe. At YGOS, Joey found something different: a genuine connection with a community that values her for who she is, beyond just a username. “I usually play Roblox with my online friends through a masked identity,” she said. “But here, I feel supported and can be myself. The mentors here actually care, listen and encourage me to express my doubts and concerns, and share about things that bring me joy.” A highlight of the event today was a gaming tournament attended by youths between the ages of 13 and 24 years old and community partners. About 120 participants, including a team from SP’s gaming interest group, competed in Mobile Legends: Bang Bang, a multiplayer online battle arena mobile game. By bringing the youths together to interact in person on a common interest in a safe, environment, the event aims to foster genuine connections and build a sense of community. Beyond the tournament, the youths explored educational and interactive booths hosted by YGOS, REACH Community Services and Fei Yue Community Services. These booths offered various outreach services such as how YGOS’ Cyber Outreach team connects with hidden youths online to draw them out of isolation. In 2023, SP contributed $750,000 to YGOS to launch the first-of-its-kind mobile youth engagement outpost with an electric vehicle, and to enable the full refurbishment of its youth centres in Woodlands and Ang Mo Kio to expand service delivery and outreach programmes.
