Media Release Electricity Tariff Revision for the Period 1 April to 30 June 2026 Singapore, 31 March 2026 – For the period from 1 April 2026 to 30 June 2026, the electricity tariffs (before GST) for households will increase by 2.1% or 0.56 cent per kWh compared with the previous quarter due to higher energy costs. The average monthly electricity bill for families living in HDB four-room flats will increase by $1.80 (before GST). The overall electricity tariff (before GST), including tariffs for non-households, will increase by an average of 2.0% or 0.52 cent per kWh compared with the previous quarter. SP Group reviews the electricity tariffs every quarter based on guidelines set by the Energy Market Authority (EMA). The energy cost component of the electricity tariffs for each quarter is set using the average natural gas prices in the first two and a half months in the preceding quarter. Accordingly, the energy cost component of the electricity tariffs from 1 April 2026 to 30 June 2026 reflects the natural gas prices from 1 January 2026 to 15 March 2026, which incorporate the increase in natural gas prices due to the Middle East conflict only from 28 February. The electricity tariffs in the subsequent quarters are expected to increase further as the full effect of the elevated natural gas prices are incorporated. Please refer to Appendix 1 for the components of the electricity tariff, Appendix 2 for the electricity tariffs approved by EMA, and Appendix 3 for the average monthly electricity bill for households. Appendix 1 BREAKDOWN OF ELECTRICITY TARIFF The electricity tariff consists of the following four components: Energy costs (paid to the generation companies): This component is adjusted quarterly to reflect changes in the cost of fuel and power generation. The fuel cost is the cost of imported natural gas, which is tied to oil prices by commercial contracts. The cost of power generation covers mainly the costs of operating the power stations, such as the manpower and maintenance costs, as well as the capital cost of the stations. Network costs (paid to SP Group): This is to recover the cost of transporting electricity through the power grid. Market Support Services Fee (paid to SP Group): This is to recover the costs of billing and meter reading, data management and retail market systems. Market Administration and Power System Operation Fee (paid to Energy Market Company and Power System Operator): This fee is reviewed annually to recover the costs of operating the electricity wholesale market and power system.

This charge varies for different load requirements and is categorised as follows: [a) Development Without Substation The service connection charge comprises the cost based on requirement in kVA of tapping supply from both the High Tension [HT) and LT networks, which includes the cost of service cables. For individual consumers without substations, the cost of LT service cable for the same capacity may vary widely depending on their locations with respect to the nearest LT mains. These consumers are not the sole beneficiaries of the extension of the LT network. To achieve a greater degree of equity in terms of cost for these general consumers, a standard cost approach is adopted by grouping consumers with similar supply requirements. The average global cost per kVA is determined based on past statistics. For example, this category of consumers which comprises mainly landed residential owners applying for the same applied load, will pay the same standard connection charge regardless of the location of their premises from the existing LT network. [b) Development With Substation The service connection charge comprises the cost based on requirement in kVA of tapping supply from the HT network and the cost of service cable. The cost of tapping supply from the HT network refers to the cost of cables and consumables used in setting up a new distribution substation. It excludes the cost of shared network assets such as switchgear, transformer and HT network cables. The cost is spread to all new consumers proportionally on a per kVA basis. For consumers with substations, their supply intake point is usually adjacent to the substation, which requires a service cable of approximately 15m in most instances. Therefore, the standard cost of service cable is computed based on a length of 15m. Consumers shall pay the additional cost for service cable exceeding 15m. In addition, consumers shall also pay for those dedicated assets, such as switchgear and transformers, which are serving them and do not benefit others.

For longer lengths, additional charges shall apply. Standard charges are only applicable to consumers who are connected to the shared network. Standard charges are not applicable to consumers where the network extension is unlikely to be shared by others. Some of these include supply to HDB premises, premises involving installation of bigger capacity cable in order to overcome the excessive voltage drop, temporary work sites, public installations and offshore island premises. These consumers will be required to pay for the full connection network cost, based on user-pay principle, as they are the main beneficiaries. B2 Service Connection Charges for HT, EHT and UHT Supply Consumers taking HT, EHT and UHT supply shall pay the cost of the service connections to their intake equipment including cables, associated equipment and facilities to effect the connection of consumers’ equipment to SPPA’s substation/network. The service connection shall cater for single contingency. Consumers requesting for additional level of contingency that exceeds the single contingency standard are required to pay for the full cost of such provision. B3 Dedicated Network/Substation The developer or consumer shall pay the full cost of all associated equipment and facilities under a dedicated network/substation scheme for which the network capacity is intended to serve the developer’s development or consumer’s premise(s) exclusively. A substation comprises land, building, electrical equipment and associated cables. A substation which serves a development or premise has to be provided and paid for by the developer or consumer. As the capacity of electrical equipment is lumpy, the substation may have excess capacity. The developer or consumer will carry the cost of this excess capacity which cannot be avoided. As this substation is required to serve mainly the development’s or consumer’s load, it is considered a dedicated substation. To reduce cost, a developer or consumer can choose to let SPPA bear the cost of the electrical equipment and associated cables, thus making the network/substation a nondedicated one. In return, SPPA must be allowed to allocate the excess capacity to other consumers. Even after the excess capacity is allocated, SPPA shall return the capacity to the developer or consumer if his demand grows later provided existing allocated capacity to other consumers can be diverted. The latter provision shall also apply to the decommissioning of the substation. At present, most substations provided by developers or consumers are non-dedicated substations.

A flat per kWh UOS rate is levied at each metered intake supply point. These are consumers who choose to buy electricity from SP Group at the regulated tariff. 2.2 Low Tension Large Consumer LT Supplies to these contestable consumers are metered on energy (kWh) on a halfhourly time-of-day basis. The respective per kWh charges shall be levied at a “Peak” and an “Off-peak” period for the energy supplied at each metered intake supply point. 2.2.1 Peak Period Charge The Peak Period Charge payable shall be the monthly charge based on the energy (in kWh) supplied to an installation during the peak period, 7.00 am to 11.00 pm, in that month. 2.2.2 Off-Peak Period Charge The Off-Peak Period Charge payable shall be the monthly charge based on the energy (in kWh) supplied to an installation during the off-peak period, 11.00 pm to 7.00 am, in that month. 3 High Tension, Extra-High Tension and Ultra-High Tension Supplies For HT (i.e. HT Small and HT Large), EHT and UHT Supplies, UOS Charges shall be levied at each metered intake supply point as follows : a. Contracted Capacity Charge; b. Peak Period Charge; c. Off-peak Period Charge; d. Reactive Power Charge; e. Uncontracted Capacity Charge, and f. Uncontracted Standby Capacity Charge (applicable to consumers with embedded generation who opt to cap their power demand drawn from the network). 3.1 Contracted Capacity Charge 3.1.1 The Contracted Capacity Charge is a monthly charge payable in any month for the Contracted Capacity at each intake supply point of a consumer. The Contracted Capacity shall be the supply capacity (in kW), which is requested by the consumer for that intake supply point. For the avoidance of doubt, and without prejudice to paragraph 3.1.3 herein, the consumer shall not be allowed to reduce the declared Contracted Capacity upon the signing of the Consumer Connection Agreement / Supply Agreement, notwithstanding the fact that the energisation of the new supply has still not taken place. 3.1.2 For a new connection, consumers are subject to a binding period of 5 years from the target date or the commissioning date for SPPA’s plant and equipment, except for the service cable, whichever is later. During the 5-year binding period, no reduction to the Contracted Capacity is allowed. For new HT, EHT and UHT connections, the minimum Contracted Capacity for each intake supply point is as follows : HT with 1 or 2 feeders HT with 3 or 4 feeders EHT UHT 1,700 kW, 12,751 kW, 25,501 kW, 85,000 kW. During the first year of the 5-year binding period, requests for intermediate incremental steps of Contracted Capacity may be made before the full Contracted Capacity is implemented. The first step shall be at least one quarter ( 1 /4) of the consumer’s requested full Contracted Capacity at each intake supply point. 3.1.3 After the initial 5-year binding period, the consumer may, by giving at least 10 business days’ notice in writing, reduce his Contracted Capacity at each intake supply point subject to the following minimum values: HT with 1 or 2 feeders HT with 3 or 4 feeders EHT UHT 850 kW, 6,375 kW, 12,750 kW, 42,500 kW. Any such reduction in Contracted Capacity shall be subject to a 1-year binding period from the effective date of the revised Contracted Capacity, i.e. the consumer shall not be entitled to make any further reduction in the Contracted Capacity within one year following any such reduction. The Market Support Services Licensee will inform the consumer of the date of their billing cycle. The consumer will be billed based on the revised Contracted Capacity for the entire billing cycle that encompasses the effective date of the revised Contracted Capacity. 3.1.4 The consumer, may, by giving at least 15 business days’ notice in writing, may be allowed to increase his Contracted Capacity, during the 5-year or 1-year binding period. The revised Contracted Capacity shall apply for the remainder of the initial 5-year binding period or for a minimum period of 1 year, whichever is later, provided SPPA is not required to install new or additional equipment. The consumer will be billed based on the revised Contracted Capacity for the entire billing cycle that encompasses the effective date of the revised Contracted Capacity. Reduction of Contracted Capacity during binding periods will not be allowed. 3.1.5 A consumer whose revised Contracted Capacity requires SPPA to install new or additional equipment shall be considered as receiving a new supply with a new 5-year binding period. 3.1.6 Subject to Clause 3.1.4 and 3.1.5, the UCC incurred by a consumer in a particular month (“UCC Month”) can be converted into Contracted Capacity Charge provided: (i) (ii) (iii) (iv) The consumer submits the request for an increase in Contracted Capacity no later than 2 weeks after the date of the bill for the UCC Month; The revised Contracted Capacity is not less than the maximum demand recorded in the UCC Month; The revised Contracted Capacity does not require the Transmission Licensee to install new or additional equipment; and Upon approval by the Transmission Licensee, the revised Contracted Capacity shall take effect on the first day of the UCC Month and thereafter shall not be reduced within one year, or the remaining of the 5-year binding period, whichever is later. 3.1.7 For a new development with landlord and tenants, the Contracted Capacity required by the landlord himself and his tenants (HT and above) must in aggregate meet the minimum values set out in paragraphs 3.1.2 to 3.1.3 above in order for the landlord to qualify for HT, EHT or UHT supplies. If landlord or its tenants (HT and above) request to revise their Contracted Capacity, the aggregate Contracted Capacity after revision must meet the minimum Contracted Capacity values and subject to the same terms and conditions for revision of Contracted Capacity set out in paragraphs 3.1.3 and 3.1.4. 3.1.8 Existing HT, EHT or UHT consumers may have Contracted Capacity below the minimum Contracted Capacity as specified in paragraphs 3.1.2 and 3.1.3. For such consumers, they may request to increase (but not decrease) their Contracted Capacity in the manner as described above. 3.2 Peak Period Charge The Peak Period Charge payable shall be the monthly charge based on the energy (in kWh) supplied to an installation during the peak period, 7.00 am to 11.00 pm, in that month. 3.3 Off-Peak Period Charge The Off-Peak Period Charge payable shall be the monthly charge based on the energy (in kWh) supplied to an installation during the off-peak period, 11.00 pm to 7.00 am, in that month. 3.4 Reactive Power Charge The Reactive Power Charge is a monthly charge payable in any month for the installation's excess kVArh consumption. The excess kVArh shall be the difference by which the installation's kVArh consumption drawn from the network in that month is greater than 62% of its kWh consumption drawn from the network in the same month. 3.5 Uncontracted Capacity Charge 3.5.1 The Uncontracted Capacity Charge is a monthly charge payable in any month for the Uncontracted Capacity utilised. The Uncontracted Capacity is the capacity in kW by which the maximum demand in kW (measured by the half-hour integration meter) exceeds the Contracted Capacity at that metered intake supply point. 3.5.2 The Uncontracted Capacity Charge shall apply to the following HT, EHT and UHT consumers : a. Normal consumers without embedded generation; b. Consumers with embedded generation whose monthly maximum demand in kW is the maximum summated demand in kW in the month, determined by summating the kW demand drawn from the network and the kW output from embedded generation (i.e. Summation Scheme); and c. Consumers with embedded generation who opt to cap their power demand in kW drawn from the network in the event that the maximum demand in kW (measured by the half-hour integration meter) exceeds the Contracted Capacity at that metered intake supply point (i.e. Capped Capacity Scheme or Extended Capped Capacity Scheme). The Uncontracted Capacity for these consumers shall be limited to 20% of the Contracted Capacity. 3.6 Uncontracted Standby Capacity Charge 3.6.1 The Uncontracted Standby Capacity Charge is a monthly charge payable in any month for the Uncontracted Standby Capacity utilised. The Uncontracted Standby Capacity Charge shall apply to those HT, EHT and UHT consumers with embedded generation who opt for the Capped Capacity Scheme or Extended Capped Capacity Scheme. 3.6.2 For Capped Capacity Scheme, the Uncontracted Standby Capacity Charge applies in the event the demand in kW drawn from the network (measured by the power meter) exceeds 120% of the Contracted Capacity at that metered intake supply point for a duration of more than 10 seconds continuously. 3.6.3 For Extended Capped Capacity Scheme, the Uncontracted Standby Capacity Charge applies in the event : • the demand in kW drawn from the network exceeds 120% and up to 200% of the Contracted Capacity at that metered intake supply point for a duration of more than 100 seconds continuously; or • the demand in kW drawn from the network exceeds 200% of the Contracted Capacity at that metered intake supply point for a duration of more than 10 seconds continuously. 3.6.4 For the avoidance of doubt, in the event Uncontracted Standby Capacity Charge applies in accordance with Clauses 3.6.2 and 3.6.3 above, Uncontracted Capacity Charge shall also be applicable for the Contracted Capacity portion which is 20% above the customer’s declared Contracted Capacity. 4 Temporary Supplies Temporary Supplies apply only to LT and HT supplies for temporary civil engineering and building construction sites.

Media Release Electricity Tariff Revision For The Period 1 April to 30 June 2023 Singapore, 31 March 2023 – For the period from 1 April to 30 June 2023, electricity tariff (before GST) will decrease by an average of 5.4% or 1.51 cents per kWh compared with the previous quarter. This is due to lower energy costs compared with the previous quarter. For households, the electricity tariff (before GST) will decrease from 28.95 to 27.43 cents per kWh for the period 1 April to 30 June 2023. The average monthly electricity bill for families living in HDB four-room flats will decrease by $4.69 (before GST). *before GST SP Group reviews the electricity tariffs every quarter based on guidelines set by the electricity industry regulator, Energy Market Authority (EMA). Please refer to Appendix 1 for the components of the electricity tariff, Appendix 2 for the tariffs approved by EMA, and Appendix 3 for the average monthly electricity bills for households. Issued by: SP Group 2 Kallang Sector Singapore 349277 www.spgroup.com.sg Appendix 1 BREAKDOWN OF ELECTRICITY TARIFF 1. The electricity tariff consists of the following four components: Energy costs (paid to the generation companies): This component is adjusted quarterly to reflect changes in the cost of fuel and power generation. The fuel cost is the cost of imported natural gas, which is tied to oil prices by commercial contracts. The cost of power generation covers mainly the costs of operating the power stations, such as the manpower and maintenance costs, as well as the capital cost of the stations. Network costs (paid to SP Group): This is to recover the cost of transporting electricity through the power grid. Market Support Services Fee (paid to SP Group): This is to recover the costs of billing and meter reading, data management, retail market systems as well as market development initiatives. Market Administration and Power System Operation Fee (paid to Energy Market Company and Power System Operator): This fee is reviewed annually to recover the costs of operating the electricity wholesale market and power system.

General Information 1.1 Purpose of this Document PowerGas is licensed by the Energy Market Authority (“Authority”) to be the Gas Transporter (“Transporter”) which owns, operates, and maintains the piped gas network in Singapore. SP PowerGrid (“SPPG”) is licensed by the Authority to be the Gas Transporter Agent to operate and maintain the piped gas network in Singapore on behalf of PowerGas. SPPG’s gas business is to plan, design, operate and maintain gas network assets in a manner that supports the delivery of safe, reliable, efficient, and quality services to customers. Under the Gas Transporter Licence, the Gas Transporter has to develop separate fees and charges for separate gas transportation services such as connection services and transportation services. This document sets out the connection policy and procedure for Natural Gas supply. 1.2 Singapore Gas Transportation System PowerGas owns an extensive gas transmission and distribution network throughout Singapore. The network is generally buried underground and transports natural gas to the western and northern parts of Singapore, and town gas to the whole of Singapore. The gas assets comprise the transmission network (operating at higher pressures), which forms the main reticulation backbone and the distribution network (operating at lower pressures). • Town gas is manufactured in Senoko Gasworks and delivered to approximately 900,000 customers in Singapore. The customers are made up of industrial, commercial, and residential gas users. Residential customers consist mainly of gas users from HDB, condominiums and landed premises. The town gas transmission network operates at 3 barg whereas the distribution network operates at pressure regimes ranging from 1 kPa to 50 kPa. Natural gas is supplied to about 200 customers and is imported from four sources (two submarine pipelines from Indonesia, one submarine pipeline from Malaysia and internationally through the Liquefied Natural Gas Terminal). Under the Gas Network Code, Gas Shippers/Retailers represent the customers that are connected to the natural gas networks. These natural gas customers are typically commercial or industrial and include all power stations. The natural gas transmission network operates mainly at two pressure regimes, 28 barg and 40 barg, and the distribution network operates at pressure regimes ranging from 3 barg to 6 barg.

Charges 4.1 Connection Policy The cost to connect a customer’s gas installation or gas fitting to the Transporter’s gas pipeline network varies from case-to-case, due to the proximity of the customer’s location and the cost of the materials and services required for the gas connection. Where possible, the Transporter will envisage to propose the most cost-effective connection to the applicant. 4.2 Connection Charge The connection charge payable for all gas connection applications is the sum of the project cost less the deductible cost, subject to a minimum connection charge of zero. The description of each of the cost components are shown below. (1) Project cost All costs related to the provision of gas connection from the Transporter’s gas pipeline network to the GSIV, including the Meter Installation (where applicable). (2) Deductible cost The Transporter’s investment value based on the committed gas demand from the applicant for the new gas connection. For distribution connections, the investment value is derived based on the net present value of the 5-Year revenue of the average consumption for each consumption category (see Appendix 8). For transmission connections, the connection charges are calculated individually on a case-bycase basis. In addition, a Last Mile Connection Charge (“LMCC”) will be levied to recover the cost of the “last mile” connection of the gas installation to the GSIV from the applicant. The natural gas transmission/distribution connection deductible cost, LMCC and unit rates used in the determination of the transmission/distribution pipeline estimated capital investment shall be reviewed and adjusted when deemed necessary by the Transporter. The Transporter reserves the right to review the connection charge paid for any new connection and seek reimbursement for the first 5 years under-recovered revenue from the Shipper/Retailer if the actual gas consumption after 5 years of operation is more than 10% below the projected gas demand declared during application.

Contractor Performance Management System Introduction 1. With effect from 1 October 2016, Singapore Power Limited and its Singaporeincorporated subsidiaries (SP Group) has implemented the SP Group’s Contractor Performance Management System (CPMS) to strengthen its partnership with and improve the safety and quality performance of its contractors. 2. Through the CPMS, SP Group aims to take a holistic approach to the selection of its contractors as part of enhancing procurement process, by looking at the performance of its contractors at a quarterly and annual basis and not only based at performance at each individual contract basis. The previous demerit scheme in respect of each contract will be abolished while an incentive and mitigation scheme that goes towards enabling contractors to improve their performance on a longer term basis is now implemented. Objectives 3. The objectives of the CPMS are: (a) (b) (c) to adopt a more holistic approach in reviewing contractors’ overall performance; to work with contractors to raise safety and quality standards; and to encourage an environment of continuous improvement by contractors. 4. In order to achieve the above objectives, CPMS will utilise the following 3 main components: (a) (b) (c) Contractor Performance Assessment (CPA); Business Under Surveillance (BUS) Programme; and Tender Evaluation Framework (TEF). SP Group CPMS V7.0 12 May 2025 1 Applicability 5. The CPMS will be applicable for procurement in relation of the following services and works: (a) (b) (c) (d) (e) (f) cable installation, cable jointing and road reinstatement; gas pipe-laying; milling and patching; transmission cable-laying; building and construction; and other road opening-related works (e.g., manhole access works). SP Group intends to broaden the scope of the CPMS to eventually apply the CPMS for procurement of other engineering-related works and services. 6. The CPMS will apply to contracts awarded on or after 1 October 2016 and any ongoing contracts which fall in any of the above categories set out in paragraph 5. All aspects of the CPMS, such as the BUS Programme and rewards and mitigations, will apply to such contracts. Contractor Performance Assessment 7. For each contract, a contractor will be assessed by the relevant SP Group project team in the following four (4) areas: (a) (b) (c) (d) Safety. Quality of Work; Project & Risk Management; and Value Added Services. These scores for each contract (Contract Quarterly Score) will be tabulated at fixed quarterly basis. The individual Contract Quarterly Scores applicable for each contract will then be averaged to derive the Contractor Quarterly Score. SP Group CPMS V7.0 12 May 2025 2 The criteria have a direct impact on risk mitigation which helps to review the way work activities are planned and executed. The objective of the enhancements is to reduce risk and improve safety at work sites. The PSR shall review the risk identification and mitigation measures to be taken during the design & construction for all contracts within SP Group. Emphasis will be given to the PSR communication to workers through the Risk Management workshops on site. ABSIS will be used to engage with the worker level to improve work processes and create a safer environment to work in. SP Group will assess the contractors’ senior management engagement with their workers through various in-house activities. 8. Examples of the factors taken into consideration in determining the individual Contract Quarterly Score are as follows Safety • Safety Performance • Site Safety Management • Safety Engagement by Management • Project Safety Review (PSR) • Risk Management workshop • Activity Based Safety Improvement System (ABSIS) Quality of Work • Documentation • Workmanship • Any damage to properties Project & Risk Management • Incident management • Cooperativeness • Meeting schedules Value Added Services • Initiatives to improve productivity and efficiency SP Group CPMS V7.0 12 May 2025 3 9. In addition to the above criteria, SP Group will also take into account the occurrence of any Critical Incidents when determining the Contractor’s Quarterly Score by applying a corresponding adjustment factor to their score. (a) The Critical Incidents includes: Critical Incidents Smoking or open flame in gas installations and electricity transmission substations Not adhering strictly to isolation procedures for live electricity or gas equipment and machinery at site Damage to Transmission Cables / Gas Pipes Damage to Distribution Cables / Gas Pipes Not anchoring safety harness while working at heights exceeding 3 metres Working in a confined space without conducting mandatory gas check Working under suspended load during lifting or excavator operations Fatality or serious injury Where Serious Injury is defined as: Serious Injuries Loss of 2 limbs Loss of both hands or of all fingers and both thumbs Loss of both feet Total loss of sight, including the loss of sight to such extent as to render the employee unable to perform any work for which eyesight is essential Total paralysis Loss of arm at shoulder Loss of arm between elbow and shoulder Injuries resulting in being permanently bedridden Loss of arm at elbow Loss of arm between wrist and elbow Loss of hand at wrist SP Group CPMS V7.0 12 May 2025 4 Loss of 4 fingers and thumb of one hand Loss of 4 fingers Loss of leg • At or above knee • Below knee Loss of foot Loss of sight of one eye Total loss of hearing (b) The Serious Incidents includes: Serious Incidents Damage to Distribution Cables/ Gas pipes affecting less than or equal to 300 customers Damage to Public assets (e.g., PUB pipes, streetlights) Note: Contractors shall not be penalised for damages to the public assets if it was unavoidable due to Authorities’ drawings that provided inaccurate factual information and the Contractor’s detection works did not provide better information. 10. At the end of each quarter, SP Group will provide each contractor a grade relative to their score to provide them timely information on their performance. The names and grades for each contractor scored in each quarter shall be available on the SP Group corporate website. 11. In the event the Contractor’s Quarterly Score is lower than 50, the contractor will be suspended from participating in any new procurement activities for the next 3 months. In the event of an occurrence of a fatality or serious injury at his work site, the main contractor and its subcontractor will be suspended from participating in any new procurement activities for 12 months (fatality) and 3 months (serious injury) respectively from the incident date. The suspended contractors and their subsidiaries are also not allowed to apply to be sub-contractors for any SP Group contracts during the suspension period. SP Group CPMS V7.0 12 May 2025 5 12. The Contractor Quarterly Scores will be aggregated on an annual basis [Contractor Annual Score]. Contractors must have at least two (2) Contractor Quarterly Scores to be included for the Contractor Annual Score computation. 13. At the end of each Assessment Year, the 5 contractors with the highest Contractor Annual Score for the year will be given an incentive of 2% of the total annual value of their respective contracts capped at $100,000.00 per year per contractor. The annual value of each contract is computed as follows: where: ACV is the annual value of a contract; ACV = A X B A is the Contract Sum divided by the Contract Period [weeks]; and B is the number of weeks [or part thereof] where Works carried out in that year under that contract. 14. The 2 contractors with the lowest annual scores will be subjected to a penalty deduction to their PQS scores in all subsequent SP Group tenders published during the next Assessment Year. In addition, they would also have to comply with performance improvement requirements specified by SP Group to address areas of deficiency. SP Group CPMS V7.0 12 May 2025 6 Business Under Surveillance (BUS) Programme 15. The BUS Programme is an educational and correctional tool aimed to partner contractors to address safety and quality issues encountered by contractors in the course of their work for the SP Group and in the longer term help improve their safety and quality standards. The BUS Programme and will be activated in the following situations: (a) (b) Occurrence of any Critical Incident; and/or 3 or more safety inspections at the project sites where major safety-related non-conformances (safety non-conformance) are observed. 16. In the event of the activation of the BUS Programme, the Contractor will be required to undergo the activities as follows: 17. Stopping work at the affected site[s] during a BUS Programme is important to allow contractors to review its safety practices and focus on its operational methods and processes with the aim of preventing further incidents from occurring again. 18. If the contractor placed on a BUS Programme is unable to meet the exit requirements at the end of the 5 th week, a further 2 weeks extension will be granted. If the contractor is still unable to meet the exit requirements at the end of the 7 th week, the contractor will be placed on a second BUS Programme to address the failure of the first BUS Programme. SP Group CPMS V7.0 12 May 2025 7 19.

Tender Evaluation Framework 21. The CPMS adopts a tender evaluation framework that comprises the following 3 Stages: 22. Stage 1 (SET) aims to inculcate a mindset of safety being the highest priority among our contractors, by selecting only likeminded contractors who have adequate safety management system and track records to work on our projects. Contractors who meet the SET requirements will be pre-qualified to participate in SP Group’s tenders for works described in paragraph 5 above. Once such pre-qualification is granted by SP to the contractors, it shall be valid for the entire Assessment Year. Any contractor which fails the Stage 1 assessment can apply for re-assessment at the start of new calendar quarter after being notified of its failure to pre-qualify.
