Other notable participants include Hillhouse, CPE, Boyu Capital, Gaoyi Asset Management, and Greenwoods Asset Management, alongside insurance and specialized funds like CPIC, ORIX, and Walden International.This diverse group of high-caliber investors signals a strong market consensus: Sigenergy is recognized as a unique player in the “AI + All-in-One PV Storage” sector, underpinned by proprietary technology, high entry barriers, and predictable growth. Beyond a mere endorsement of the company, this capital influx confirms the market’s conviction that “AI-native” architecture is the definitive standard for next-generation energy storage.Market confidence is supported by Sigenergy’s rapid scale-up. According to the prospectus, the company’s revenue grew from RMB 58.30 million in 2023 to RMB 9.00 billion in 2025, increased 154.4 times in two years. During this period, gross margins expanded from 31.3% to 50.1%, with an adjusted net margin reaching 35.9%. These figures validate the commercial viability of Sigenergy’s “AI-native” technology path.Differentiation Through “AI-Native” TechnologyUnlike traditional “hardware-first, AI-enabled” peers, the company established a more thorough “AI-native” path by integrating artificial intelligence across product design, manufacturing, and business models, the company has achieved a system that is inherently intelligent and capable of continuous evolution.Its flagship product, SigenStor, is a five-in-one system that combines an inverter, EV DC charging module, and battery pack into a modular, stackable unit which achieves a deep integration of power electronics, cloud and AI technologies, enhances product performance while delivering a more convenient user experience.The actual value of system’s “AI-native” capabilities is particularly effective in markets with dynamic electricity pricing. Facing fluctuations on an hourly or even minute-by-minute basis, traditional “charge at low, use at high” strategies based on fixed rules are no longer sufficient. By analyzing real-time prices, weather forecasts, and consumer habits, the system optimizes energy scheduling. In the Swedish market, SigenStor helped users reduce electricity costs by an average of 70.3%, showing the effective translation from AI technology into tangible financial benefits.Sigenergy continuously strengthens its competitive edge through a “Data-Intelligence” closed-loop. As global install base grows, the system leverages real-world operational data to undergo autonomous learning and optimization. This evolution directly translates into superior economic returns for users, which in turn fosters brand loyalty and higher retention. This data-driven cycle creates a powerful network effect, establishing a formidable, long-term barrier to entry in the Energy AI sector.Since its launch, SigenStor has established a strong global presence through its unique value proposition. According to Frost & Sullivan, Sigenergy has become the world No.1 provider of stackable distributed PV and storage all-in-one solutions in 2024, securing a 28.6% market share. Further data from SunWiz confirms that in 2025, the company ranked first in the under-1000kWh segment across Australia, Ireland, and South Africa, while maintaining a top-tier position in the UK, Sweden, and the Netherlands. This deep penetration into high-value markets has delivered significant commercial returns and reinforced Sigenergy’s brand equity. As the company expands into the Asia-Pacific and Latin American regions, its growth trajectory remains robust.To support the trajectory, the company has built a robust manufacturing footprint with production bases in Lingang and Jinqiao, Shanghai, as well as Nantong, Jiangsu. By the end of 2025, the company achieved an annual design capacity of nearly 360,000 inverters and over 5.6 GWh of energy storage batteries. This infrastructure provides a stable foundation for the company’s ongoing global expansion.The successful HKEX listing marks a significant milestone in Sigenergy’s commitment to innovation and recognizes its substantial growth potential. Entering this new chapter, and with the support of premier institutional investors, Sigenergy will focus on optimizing resource integration and accelerating its global ‘AI + Energy Storage’ strategy. By solidifying its technological leadership and market presence, the company aims to build a sustainable foundation for long-term value creation.For inquiries, please contact:EVER BLOOM (HK) COMMUNICATIONS CONSULTANTS GROUP LIMITEDMs. Claire ZhangTel: (852)3468 8171Email: project_alps.list@everbloom.com.cn Copyright 2026 ACN Newswire via SeaPRwire.com.

BRISBANE, AUS, Apr 15, 2026 - (ACN Newswire via SeaPRwire.com) - Graphene Manufacturing Group Ltd. (TSXV: GMG) (OTCQX: GMGMF) ("GMG" or the "Company") is pleased to provide the latest progress update on the Graphene Aluminium-Ion Battery technology ("G+A CELLS") being developed by GMG and the University of Queensland ("UQ") under a Joint Development Agreement with Rio Tinto, one of the world's largest metals and mining groups, and with the support of the Battery Innovation Center of Indiana ("BIC") in the United States of America.The GMG G+A CELLS have now demonstrated superior performance characteristics when compared to a representative market leading ultra-fast charging batteries, the Lithium Titanate Oxide ("LTO") batteries, which can be sold at a premium price of up to US$1200/kWh.1Figure 1 shows the current energy density of G+A CELLS, based on BIC testing, and shows the doubling in performance (26 to 49 Wh/kg) since the previous announcement in December 20252 and in comparison, to a representative market leading fast charging high power LTO batteries.Figure 1: Increase in Energy Density for G+A CELLS since December '25 UpdateTo view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/8082/292641_figure1.jpgFigure 2 shows the charge and discharge curves for the G+A CELLS when charged in 6 minutes (10C) and 60 minutes (1C). The energy density of the cells for the G+A CELLS when charged in 60 minutes (1C) is now 101 Wh/kg when charging to 100% State of Charge (SOC) which is an increase from 58 Wh/kg from the previous update. This shows the G+A CELLS have a nominal voltage of approximately 3.2 Volts (an increase from 3.0 Volts in the previous update). The G+A CELLS maintained performance over hundreds of cycles at 6-minute fast charging rate (10C).Figure 2: Battery performance curves of G+A CELLS at 60 min and 6min charge (1C & 10C)To view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/8082/292641_9a72ca9bb4963a29_001full.jpgBob Galyen, GMG Non-Executive Director and former CTO of CATL - the largest battery manufacturer in the world, commented: "With the possibility of charging from empty to full in around six minutes, this chemistry fundamentally changes how designers can think about electric vehicles, consumer electronics, and stationary storage. Instead of planning around long charge stops with large packs, engineers can optimise for rapid energy turnaround, with higher power, and safer, with GMG's battery made from abundant raw materials. Lithium-ion will remain a key part of the energy landscape for years to come, but its limitations in fast charging, temperature tolerance, and critical-mineral supply are increasingly evident. By leveraging aluminium and graphene, the GMG team is demonstrating a pathway to reduce reliance on traditional lithium-based systems and or combinatorial systems with multiple battery technologies while delivering step-change improvements in charge time and power density. This is not an incremental tweak to existing cells - it is a new platform that can open markets and use cases that were previously uneconomic or impractical. The companies that adapt quickest to this shift will lead the next wave of electrification, and GMG intends to be at the centre of that transition with graphene aluminium-ion technology."Standard commercial Lithium Nickel Manganese Cobalt ("LNMC") and Lithium Iron Phosphate ("LFP") battery cells for electric vehicles and stationary storage are NOT designed for continuous 6-minute charging (10C); typical recommended charge rates are ≤1 hour (1C), often 2 hours (0.5C), with only limited fast charge operation. Only specialized high-power cell designs like LTO battery cells can tolerate charge rates of 6 minutes (10C).3GMG has now developed a completely new hybrid electrolyte that is chloride free and non-corrosive, unlike common aluminium battery electrolytes, along with a complex cathode and anode technology that enables very stable fast charging over hundreds of cycles. The substrate for both the cathode and anode in the G+A CELLS is aluminium foil - which provides significant cost and weight savings compared with copper, the substrate material used in most lithium and sodium-ion batteries. GMG's technology does not include the use of lithium or copper. The Company has submitted an additional patent application covering these new developments.GMG believes that it has significantly met the key target specification requirements for use in heavy mobile equipment, as shown in Figure 3, its main targeted use case, including:- Charging in under 6 minutes;- Energy density > 100 Wh/kg after 1 hour of charging; and- Safe (no Lithium).The next battery development steps include the following activities:- Test and show cycle life up to 10,000 cycles- Test and show ambient temperature impacts- Test and show standard safety testing- Test and show no thermal battery management system needed Figure 3: G+A CELLS Battery Use Case - heavy mobile equipmentTo view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/8082/292641_figure3.jpgCraig Nicol, GMG Managing Director and CEO, commented: "This is a significant step up from where we were at with battery performance in December 2025 and we see the required performance for our targeted use case being largely met - which means we can start to put together the next stages of the battery maturation program - including partnerships and manufacturing plans."GMG management believes that the G+A CELLS can eventually achieve over 160 Wh/kg when charged in 1 hour, and over 80 Wh/kg when charged in 6 minutes with further development of the cathode, anode, electrolyte and component weights.Figure 4 shows the latest G+A CELLS in pouch format:Figure 4: Current Multi-Layer G+A CELLTo view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/8082/292641_figure4.jpgBattery Technology Readiness LevelThe battery technology readiness level ("BTRL") of the G+A CELLS remains at Level 4, whilst significantly progressed through this level as shown in Figure 5. GMG is currently in the process of completing the optimization of the electrochemical behaviour for the pouch cells via ongoing laboratory experimentation. Through collaboration with BIC, it is anticipated that the battery technology readiness will ultimately progress to BTRL 7 and 8 since the equipment and processes needed to produce the G+A CELLS are the same as those employed to make Lithium-Ion Batteries, though no definitive timeline for achievement can be provided at this time.Figure 5: Battery Technology Readiness Level (BTRL)To view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/8082/292641_9a72ca9bb4963a29_004full.jpgThe Company is confident it can meet the overall timeline, as seen in Figure 6, of its battery cell roadmap that calls for testing of cells with customers in 2026 and small commercial production with support of various partners, including BIC, in 2027.Figure 6: Battery Cell RoadmapTo view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/8082/292641_9a72ca9bb4963a29_005full.jpgNext Steps Toward Commercialisation & Market ApplicationsJack Perkowski, GMG Non-Executive Chairman and Director, commented: "I am extremely proud that GMG has progressed its battery to this stage - the Company is getting very close to final commercialisation steps. We look forward to providing further updates as GMG progresses the development of its battery technology."The Company continues to see a broad range of potential applications for a completed G+A CELLS - utilising its ultra-high power-density and economic energy density characteristics. Along with Rio Tinto, a range of global companies have confidentially expressed their interest in working with GMG in the following vertical sectors:Figure 7: Market ApplicationsTo view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/8082/292641_9a72ca9bb4963a29_006full.jpgCurrently, GMG believes it will use a plastic battery pack design, similar to Figure 8, to hold the battery pouch cells - reducing the weight, cost and complexity relative to using a metal case. Using a plastic battery pack is possible for two main reasons - GMG believes that its battery will not require a thermal management system or the fireproofing precautions provided by the metal case in a lithium-ion battery. Using plastic will increase the comparative energy density of G+A CELL packs when compared to lithium-ion batteries.Figure 8: Expected Battery Pack for GMG's G+A CELLS Pouch FormatTo view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/8082/292641_9a72ca9bb4963a29_007full.jpgComparison and Market Review: LTO Batteries As shown in Figure 9 below, the performance of GMG's G+A CELL technology is already very similar to representative LTO batteries.Figure 9: Comparison of GMG's G+A CELLS to Lithium Titanate Oxide (LTO) BatteryTo view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/8082/292641_figure9.jpg LTO batteries are sold at a premium to LFP and LNMC batteries, which are the main chemistries used in electric vehicles and energy storage systems, and are also widely used in other electronic applications due to their high performance and long cycle life. The material and manufacturing costs for G+A CELLS are expected to be similar to, or less than, the cost to manufacture standard lithium-ion batteries, but substantially lower than the costs to produce LTO batteries.LTO batteries have energy density ranging from 50 - 80 Wh/kg.6 The LTO product is sold globally for use in many applications — with a total of US$5.67 billion sales per annum in 2025. Sales of LTO batteries are expected to grow at 16.9% per annum to an estimated US$ 12.5 billion by 2030. The major manufacturers of LTO batteries include Toshiba, Gree, Microvast and CATL.Further details on applications for the LTO battery from Mordor Intelligence7 are described below. In many of the use cases for LTO batteries, GMG believes that its G+A CELLS can be substituted at a substantially lower cost.Commercial Vehicles: Automotive, primarily buses, refuse trucks, and drayage tractors rather than passenger cars, is the largest user of LTO batteries. Fleets realize five-year total-cost-of-ownership parity once fuel savings and lower maintenance offset higher upfront prices.Fast-charging Electric Buses and Trucks: Transit authorities need battery systems that accept repeated high-power "opportunity charges" during short layovers. LTO cells replenish 80% capacity in roughly five minutes, allowing operators to shrink fleet size without sacrificing route frequency. U.S. Low-No Emission Bus grants earmark more than US$1.5 billion per year, with bid specifications that explicitly reference rapid-charge capability. Parallel subsidy programs in China reimburse up to CNY 80,000 (US$ 11,396) per new-energy bus, accelerating volume deployment in provincial capitals.Hybrid and BEV: Regenerative braking and high-C-rate acceleration favour the use of LTO batteries. Use in fast-charge EV stations is growing rapidly as ride-hailing fleets adopt swap-ready models.Stationary Storage: Utility-scale batteries now cycle multiple times per day for frequency regulation, peak shaving, and voltage support. Energy-storage-system integrators adopt LTO batteries for grid-frequency response where state-of-charge swings are shallow but frequent.Industrial Robotics: LTO batteries are used in continuous-duty forklifts that require partial charges during operator breaks.Aerospace and Defense: Unmanned aerial vehicles, missile auxiliaries, and soldier-worn power banks operating from -40 °C to +60 °C ambient.5-minute Battery-Swap Stations: Battery-as-a-service platforms require ultra-fast turnaround and high cycle life. CATL confirmed plans to install 1,000 swap stations in 2025 and 30,000-40,000 by 2030, each requiring packs that tolerate thousands of rapid exchanges without degradation.Sub-10 kWh Packs: Cordless construction tools, autonomous ground vehicles, and medical carts select LTO batteries to bypass daily pack swaps.12V starter replacement to Lead acid: GMG's G+A CELLS battery technology would be a viable 12 V starter-battery replacement for lead-acid, offering lower weight, longer cycle life, good low-temperature performance and improved cold-cranking capability, together with excellent tolerance to storage at 0% state of charge. In suitable system designs, the chemistry's stable voltage behaviour can also reduce balancing requirements and simplify battery management, helping to lower overall system cost.Lifecycle Procurement Preference: Many government procurement frameworks now weigh lifecycle reliability higher than purchase price. For example, New Mexico awarded a US$ 400 million bus electrification contract that included stringent thermal-runaway resistance metrics. Europe's Clean Industrial Deal allocates capital for storage technologies that stabilize renewables, aligning well with LTO batteries' fast-response profile.Cylindrical Cells: accounted for 37.7% of LTO battery sales in 2024 as entrenched production lines and robust steel casings satisfied heavy-duty demand. Pouch designs address aerospace weight requirements and constrained dashboards in autonomous robots.Summary of Important Milestones for GMG's G+A CELLS Development: MonthImportant Milestones in the

Together with its subsidiary OBI Pharma USA, Inc., the company is dedicated to developing innovative cancer therapeutics to provide new treatment options for patients with urgent medical needs.OBI's research efforts center on novel antibody-drug conjugates (ADC). Through its patented next-generation conjugation technology platform, Obrion™, OBI has established diverse ADC design modalities. The platform integrates proprietary conjugation and linker technologies, including GlycOBI®, GlycOBI DUO®, EndoSymeOBI®, HYPrOBI®, and the novel irreversible cysteine-conjugation technology ThiOBI® , to advance next-generation ADC solutions. OBI has developed a next-generation suite of ADC programs. These include monospecific ADCs such as OBI-902 (TROP2), which is under Ph1 clinical evaluation, and OBI-904 (Nectin-4); a bispecific single-payload ADC, OBI-201 (HER2 x TROP2); and a bispecific dual-payload ADC, OBI-221 (cMET x HER3). To broaden the applicability of the HYPrOBI® linker technology, OBI has further developed the ThiOBI® technology to enable irreversible cysteine-based conjugation. In addition to its ADC programs, OBI's assets include OBI-3424, a first-in-class AKR1C3-targeted small-molecule prodrug that selectively releases a potent DNA-alkylating agent in the presence of the aldo-keto reductase 1C3 enzyme, which is highly expressed in certain tumors. Additional information can be found at www.obipharma.com.About OBI-902 and OBI-992OBI-902 is a TROP2-targeted antibody-drug conjugate (ADC) that carries a potent topoisomerase I inhibitor payload to kill tumor cells with a drug-antibody ratio (DAR) of 4. TROP2 is highly expressed in a variety of solid tumors such as breast, lung, biliary, bile duct (cholangiocarcinoma), ovarian, gastric, and many other cancer types, rendering it an ideal target for cancer therapy.OBI-902 is a novel site-specific glycan-conjugated ADC using OBI's proprietary GlycOBI® platform, which provides improved stability and enhanced hydrophilicity. OBI-902 demonstrated remarkable antitumor efficacy across multiple tumors, including NSCLC, triple-negative breast cancer (TNBC), and gastric cancer, improved pharmacokinetic characteristics, and a favorable safety profile in various animal models. The IND of OBI-902 was cleared by the United States Food and Drug Administration (US FDA) on April 30, 2025, received Orphan Drug Designation (ODD) from the US FDA for cholangiocarcinoma on Nov. 16, 2025, and gastric cancer (GC), including gastroesophageal junction cancer (GEJC) on December 5, 2025.The Phase 1/2 Study (NCT07124117) is ongoing, with completion of the Phase 1a portion targeted for 1H 2027.OBI-992 is a TROP2-targeted antibody-drug conjugate (ADC) that carries a potent topoisomerase I inhibitor payload with drug-to-antibody ratio of 4 (DAR 4) via a cysteine conjugated, hydrophilic and enzyme-cleavable linker. OBI-992 remains stable in circulation and delivers this cytotoxic payload to TROP2-expressing tumor cells, leading to tumor cell death while avoiding off-target toxicities.The US FDA cleared the IND application for OBI-992 in Jan 2024 and subsequently granted Orphan Drug Designation for the treatment of gastric cancer, including GEJC in Aug 2024. The Phase 1/2 Study (NCT06480240) has reached the putative Recommended Phase 2 Dose (pRP2D) and Phase I completion is targeted for 1H 2027.Since December 2021, OBI has been granted by Biosion, Inc. (www.biosion.com) an exclusive license to a TROP2 targeting antibody amino acid sequence in all jurisdictions except Mainland China, Hong Kong and Macau. Biosion holds exclusive rights to that antibody sequence in Mainland China, Hong Kong and Macau. OBI holds commercial rights to OBI-992 and OBI-902 in all jurisdictions except Mainland China, Hong Kong and Macau, while Biosion holds commercial rights to OBI-992 and OBI-902 in Mainland China, Hong Kong and Macau.About OBI-904OBI-904 is an antibody-drug conjugate (ADC) comprised of a monoclonal antibody specifically targeting Nectin-4 (Nectin cell adhesion molecule 4), linked to a potent topoisomerase I inhibitor payload with Drug-to-Antibody Ratio of 8 (DAR8) through OBI's proprietary GlycOBI® ADC enabling technologies, powered by a dual-function enzyme, EndoSymeOBI®, and a novel linker, HYPrOBI®. It is a potentially first-in-class and best-in-class glycan-based ADC designed to target multiple cancer types that express Nectin-4. Antitumor activity has been shown across several animal disease models, including HNSCC, CRC, TNBC, cervical and sarcoma cancers; OBI-904 has demonstrated a favorable safety profile in a repeat dose toxicity study in monkeys, and is now in the pre-IND stage of development.About OBI-201OBI-201 is a TROP2 x HER2 bispecific ADC generated by OBI GlycOBI® ADC enabling technologies conjugated with a topoisomerase I inhibitor. Notably, OBI is the first to demonstrate that HER2 and TROP2 can interact and form a protein complex on the cell surface-a groundbreaking discovery facilitated through collaboration with a specialized AI drug discovery partner. OBI-201 offers several advantages over mono-specific TROP2 or HER2 ADCs. By targeting both antigens, it broadens tumor coverage, especially in cancers with heterogeneous or low expression of either target. Dual targeting can enhance tumor selectivity, binding avidity, and internalization, improving payload delivery to cancer cells while potentially reducing toxicity to normal cells. OBI-201 may overcome resistance associated with downregulation of targets after treatment by certain monospecific ADCs.Animal studies revealed that OBI-201 demonstrated significantly superior anti-tumor activity compared to single-target ADCs in drug-resistant breast cancer models with extremely low HER2 expression. OBI-201 was able to sustain tumor growth suppression, indicating its potential to overcome multiple drug-resistance mechanisms. OBI-201 is a next-generation bispecific ADC poised to break through the limitations of single-target ADCs, potentially offering patients a more comprehensive and durable treatment option.About OBI-221OBI-221 is a Bispecific-Dual Payload ADC (BsDpADC), generated by OBI GlycOBI DUO® technologies, targeting cMET and HER3, conjugated with dual payload of MMAE and topoisomerase I inhibitor.In clinical practice, EGFR-targeted therapies have become a key strategy for treating non-small cell lung cancer (NSCLC) and colorectal cancer (CRC) patients. However, tumors often rapidly develop resistance by upregulating cMET and HER3 that, in turn, sustain tumor growth. Moreover, high expressions of cMET and HER3 have been observed in gastric cancer, head and neck cancer, and various other solid tumors, further underscoring the unmet medical needs.To address this challenge, OBI Pharma leverages its proprietary GlycOBI DUO® platform and HYPrOBI® linker to develop a novel bispecific dual-payload antibody-drug conjugate (BsDpADC)-OBI-221. This therapeutic agent simultaneously targets cMET and HER3 while delivering synergistic cytotoxic agents, effectively combating tumor resistance and heterogeneity. This breakthrough design not only addresses an unmet medical need but also represents a forward-looking strategy for next-generation ADC development.OBI-221 holds meaningful potential to overcome resistance to existing EGFR-targeted therapies, potentially offering patients more targeted treatment options while delivering substantial clinical value.About GlycOBI®OBI has developed a unique glycan-based, site-specific ADC technology (GlycOBI®), designed in a Plug and Play format that is compatible with any antibodies, linkers, and payloads, and supports various drug-antibody ratios (DAR)(up to 16). Powered by OBI's proprietary dual-function enzymatic technology EndoSymeOBI® and its hydrophilic linker technology HYPrOBI®, GlycOBI®, a core component of OBI's Obrion™ ADC technology family, enables the generation of site-specific and homogeneous ADCs through an efficient, scalable and streamlined two-step, one-pot conjugation process under GMP conditions.During the conjugation process, GlycOBI® avoids disrupting the antibody structure and ensures that the resulting ADC retains biophysical characteristics comparable to the native antibody. In addition, OBI's linker technology improves payload conjugation efficiency and reduces the propensity for aggregation or degradation, further supporting a stable and well-controlled ADC manufacturing process. GlycOBI® has overcome limitations commonly associated with traditional ADC approaches and has demonstrated improved antitumor activity and stability in various in vivo studies. Notably, the platform supports the conjugation of both cytotoxic small-molecule inhibitors and highly hydrophobic degraders, expanding its applicability to next-generation modalities such as DACs.About GlycOBI DUO®GlycOBI DUO® is a next-generation dual-payload antibody-drug conjugate (ADC) technology built on the GlycOBI® site-specific conjugation platform and its proprietary enzymatic conjugation strategy.
