SINGAPORE, October 14, 2025 (GLOBE NEWSWIRE) -- Bitdeer Technologies Group (NASDAQ: BTDR) (“Bitdeer” or the “Company”), a world-leading technology company for Bitcoin mining, today announced its unaudited mining and operations updates for September 2025.

Operational Update

● Self-mining: 452 Bitcoins mined, an increase of ~20.5% from August 2025 due to higher average self-mining hashrate from energization of SEALMINERs. 35.0 EH/s deployed. On track to reach 40 EH/s at the end of October. After October, Bitdeer will continue deploying SEALMINER mining rigs for self-mining and concurrently begin retiring all third-party, older-generation rigs to further enhance profitability and fleet efficiency.

● Mining Rig Manufacturing and R&D:

o SEALMINER A2:

o Total of 34.2 EH/s in mining rigs have been manufactured and an additional 2.8 EH/s are in final assembly as of end of September 2025.

o Of the 34.2 EH/s mining rigs that have been manufactured:

● External-sales: 6.1 EH/s of mining rigs have been shipped to external customers, including 0.1 EH/s that were shipped in September.

● Self-mining:

● 22.6 EH/s of mining rigs have been deployed in U.S., Tydal, Norway and Jigmeling, Bhutan, including 4.6 EH/s in September 2025.

● 5.5 EH/s of mining rigs are in-transit to Bitdeer’s sites in Norway and Bhutan.

o SEALMINER A3:

o Launched in September, the A3 series includes four models:

● Two air-cooling models A3 Air and A3 Pro Air, achieving a power efficiency of 12.5 J/TH ~ 14 J/TH and a hashrate of 260 TH/s ~ 290 TH/s.

● Two hydro-cooling models A3 Hydro and A3 Pro Hydro, reaching a power efficiency of 12.5 J/TH ~ 13.5 J/TH and a hashrate of 500 TH/s ~ 660 TH/s.

● Commenced mass production and expect initial deliveries/shipments in October 2025 for self-mining.

o SEALMINER A4:

o Planning two different chip designs of SEAL04 to ensure success.

o The first SEAL04 chip tape out was completed in September and are currently under testing. Initial results from the early samples demonstrated sub-10 J/TH power efficiency at the chip level, though still above the 5 J/TH target.

o Awaiting further sample testing to verify the feasibility of achieving the 5 J/TH chip-level power efficiency goal on the first SEAL04. Nevertheless, Bitdeer is now confident that the first SEAL04 chip is ready for mass production and will deliver significant power efficiency improvements.

o The SEAL04 with the new architecture is still expected to reach a target chip level efficiency of 5 J/TH.

o U.S. Manufacturing: Bitdeer’s U.S. factory is actively in planning and preparation.

● HPC/AI:

o As of September, Bitdeer allowed its LOI (Letter of Intent) with its development partner to expire in order to significantly expand its direct role in the HPC/AI data center market. In conjunction, Bitdeer has initiated design and layout planning for the Clarington, Ohio site. The new data center will be suitable for Bitcoin mining, with core infrastructure designed from the start to enable easy conversion into an AI data center with redundancy and other critical design elements to ensure flexibility and scalability.

o Actively recruiting US based in-house experts across multiple AI data center disciplines.

o HPC/AI priority remains Clarington, Ohio, where the local utility has confirmed that the full 570 MW will be available by the end of Q3 2026—nearly a year earlier than prior expectations. Teams are targeting substation energization in the first half of 2027.

o Bitdeer also plans to convert its 175 MW Tydal Phase 2 site into an AI data center with expected completion date of Q4 2026. This site is expected to support 164 MW of key IT load after applying various security redundancy considerations. During the conversion process, mining operations will be minimally impacted, as the Tydal, Phase 2 design had already incorporated potential conversion from Bitcoin mining to an AI data center. The capital expenditure required for this conversion will be significantly lower than the average cost of constructing a new AI data center in the U.S or Norway.

o Bitdeer is also working on converting its Wenatchee 13 MW site into an AI data center with modular data center technology.

2

o Bitdeer is also sourcing data center resources in Southeast Asia, either through rental arrangements or self-built facilities. By the end of 2026, Bitdeer expects to operate more than 200 MW of IT load dedicated to AI computing, the majority of which will be owned by Bitdeer. Bitdeer plans to pursue two business models in parallel or in combination — colocation services and AI factory operations.

o Bitdeer sees sustained imbalance between the growing demand and limited supply of AI computing power, and expects it to extend through 2027. In the most optimistic scenario, Bitdeer plans to acquire GPUs for cloud deployment and convert the entire 200 MW of IT load into an AI factory, potentially generating an annualized revenue run-rate (ARR) exceeding US$2 billion at the end of 2026.

o Bitdeer.AI, Bitdeer’s neo cloud business, reached US$8 million AI cloud ARR in September from providing GPU cloud services, with significant growth expected in the remaining three months of 2025. Cloud services has 584 GPUs as of September 2025, of which 501 GPUs are under subscribed, with a utilization rate of approximately 86%. The un-utilized GPUs are B200 GPUs, which were newly installed at the end of September, and are being tested by customers. Bitdeer anticipates full deployment of 1,160 GPUs by year-end.

o Bitdeer is concurrently securing procurement agreements for NVIDIA’s next-generation GB300 and B300 systems.

● Infrastructure:

o Tydal, Norway (Hydro): All 175 MW is energized.

o Jigmeling, Bhutan: All 500 MW is energized.

o Niles, Ohio: Officially launched 300 MW grid-interconnected site in Niles, Ohio with a target energization date of Q1 2029.

o Includes 41.8 acres of owned land and an interconnection agreement with FirstEnergy.

o Located approximately 1 hour away from existing Massillon Ohio site and 2 hours away from Clarington Ohio site.

o Total global power pipeline: Increased to 3 GW.

Management Commentary

“In September, we allowed our LOI with our development partner to expire,” said Matt Kong, Chief Business Officer at Bitdeer. “While we remain free to collaborate with this partner in the future, we have chosen to significantly expand our direct role in the HPC/AI data center market. Our expanded initiatives include negotiating directly with potential tenants, building relationships with EPCs specializing in data centers, developing proprietary AI data centers and hiring in-house experts across multiple AI data center disciplines. In parallel, we are accelerating the development of additional sites for HPC/AI data centers at our Clarington, Tydal, and Wenatchee sites. This push is driven by a marked increase in inbound interest in our power assets, which has become a strong catalyst for expanding our efforts.”

Mr. Kong continued, “Our ASICs and self-mining operational team continued to execute. In September, our first SEAL04 chip tape out was completed and initial testing demonstrates significant efficiency improvements compared to existing chips. Further, we successfully launched our SEALMINER A3 series with our Pro versions boasting a power efficiency of 12.5 J/TH. Mass production began in September and initial shipments are expected in October. In addition, our self-mining hashrate grew to 35 EH/s and remain on track to achieve 40 EH/s by end of October. Over the coming quarters, we will continue expanding our SEALMINER fleet into our near-term global power capacity, putting us on track to become one of the largest vertically integrated miners in the world.”
