SecondQuarter 2025 Financial Results
SINGAPORE, August 15, 2025 (GLOBE NEWSWIRE) – BitFuFu Inc. (“BitFuFu” or the “Company”) (NASDAQ: FUFU), a world-leading Bitcoin miner and mining services innovator, today announced its unaudited financial results for the quarter ended June 30, 2025.
SecondQuarter 2025 Financial Highlights
| ● | BitFuFu<br> delivered robust sequential growth in Q2 2025, with revenue increasing 47.9% quarter-over-quarter<br> to $115.4 million, driven by accelerating demand for cloud-mining solutions and strategic<br> expansion of mining capacity. Despite the industry-wide impact of the April 2024 Bitcoin<br> halving and increased network difficulty, our cloud-mining product offerings remained competitive,<br> supported by efficient operations, cost-effective infrastructure, and scalable service capabilities. | |||
|---|---|---|---|---|
| Three<br> Months Ended June 30, | ||||
| --- | --- | --- | --- | --- |
| Business<br> Segment | Revenue<br> ( millions) | Percentage | ||
| Cloud mining solutions | 81.7 | % | ||
| Self-mining operations | 12.8 | % | ||
| Mining equipment sales | 4.5 | % | ||
| Other | 1.0 | % | ||
| Total revenues | 100 | % |
All values are in US Dollars.
Revenue from cloud-mining increased by 22.3% period-over-period to $94.3 million, marking the highest second quarter in the Company’s history, as the platform attracted record institutional participation and repeating customer purchases. The significant increase in revenue from cloud-mining solutions reflected growing customer demand for accessible and flexible mining services.
| ● | Net<br> income was $47.1 million, which included an unrealized fair value gain of $39.6 million from<br> the increase in the price of Bitcoin. This compares to net income of $1.3 million in the<br> same period of 2024, which included an unrealized fair value loss of $16.4 million. |
|---|---|
| ● | Adjusted<br> EBITDA (a non-GAAP metric) increased to $60.7 million, compared to $8.3 million in the same<br> period of 2024. |
| --- | --- |
| ● | For<br> the three months ended June 30, 2025, basic and diluted earnings per ordinary share were<br> US$0.29 and US$0.28, respectively, compared to US$0.01 for both in the same period of 2024. |
| --- | --- |
| ● | Combined<br> balance of cash and cash equivalents and digital assets^1^<br> were $211.4 million as of June 30, 2025, representing an increase<br> of 25.8% from $168.1 million as of December<br> 31, 2024. |
| --- | --- |
“We delivered strong financial results in the second quarter, generating net income of $47.1 million—a sharp turnaround from a small loss in the first quarter. This performance more than offsets the impact of last year’s Bitcoin halving and higher network difficulty, demonstrating the strength of our business model and the dedication of the BitFuFu team,” said Leo Lu, Chairman and Chief Executive Officer. “Our total managed hash rate reached a record 36.2 EH/s and hosting capacity grew to 728 MW as of quarter-end, expanding further in July to 38.6 EH/s and 752 MW.
| ^1^ | The<br> BTC collateral receivables are not included in the balance of digital assets; and BTC was<br> measured at fair value in the Company’s financials for the quarter ended June 30, 2025. |

“With market sentiment toward Bitcoin remaining strongly positive and prices expected to rise further through the remainder of 2025 and beyond, we believe our expanding infrastructure, diversified mining operations, and continued innovation position us to seize new opportunities, strengthen our leadership in the sector, and deliver sustainable, long-term value for our shareholders.”

SecondQuarter 2025 Financial Results
Revenue
Total revenue in the second quarter of 2025 was $115.4 million, representing a decrease of 10.8% from $129.4 million in the same period of 2024, primarily due to a decline in self-mining revenue.
Revenue from cloud-mining solutions in the second quarter of 2025 was $94.3 million, representing a increase of 22.3% from $77.1 million in the same period of 2024. This increase was primarily due to (i) increases in demand for cloud mining services, (ii) repeat purchases from both existing customers and new customers acquired during the year of 2025, and (iii) continued growth in our managed hash rate and expansion of our power capacity. BitFuFu realized a net dollar retention rate of 59.5% for the second quarter of 2025, which was calculated by dividing the amount of recurring revenue in the second quarter of 2025 by the amount of revenue in the second quarter of 2024, reflecting continuous customer demands and the Company’s ability to maintain a substantial portion of revenue from existing customers.

|---|
Revenue from Bitcoin self-mining operations in the second quarter of 2025 was $14.8 million, representing a decrease of 71.0% from $51.1 million in the same period of 2024. The decrease was primarily due to the April 2024 Bitcoin “halving event” and increasing blockchain network difficulty, which together led to a 49% period-over-period decrease in the average BTC daily earnings per tera-hash in the second quarter of 2025; and a 61.7% period-over-period decrease in the average hash rate used for self-mining operations, which was partially offset by the increase in BTC price from an average of $65,900 in the second quarter of 2024 to $98,800 in the second quarter of 2025.
Revenue from mining equipment sales in the second quarter was $5.2 million, a substantial increase from $0.1 million in the same period of 2024. This growth reflects strong demand for mining machines, supported by the sustained upward trend in Bitcoin prices. Building on this momentum, the Company is leveraging its strategic partnerships to further expand machine sales and capture new market opportunities.
Costof Revenue
Cost of revenue in the second quarter of 2025 was $102.5 million, representing a decrease of 13.4% from $118.4 million in the second quarter of 2024. The decrease was in line with the decline in total revenue and was primarily driven by a reduction in per tera-hash electricity costs, as well as the Company’s ongoing efforts to improve cost efficiency through procurement optimization.
OperatingExpenses
Sales and marketing expenses, and research and development expenses in the second quarter of 2025 were $0.6 million and $0.4 million, respectively, approximately in-line with the same period of 2024. General and administrative expenses in the second quarter of 2025 were $2.1 million, compared to $1.4 million in the same period of 2024.
The Company recognized a non-cash fair value gain of $31.3 million on BTC and a non-cash fair value gain of $8.3 million on BTC receivables or payables, reflecting a favorable mark-to-market adjustment as of June 30, 2025, compared to March 31, 2025. In addition, the Company recorded a $3.8 million gain on the disposal of digital assets during the quarter, as the selling price of BTC exceeded its carrying value at the end of the prior quarter.
NetIncome
Net income in the second quarter of 2025 was $47.1 million, compared to the net income of $1.3 million in the same period of 2024, including an unrealized fair value gain of $39.6 million as mentioned above.
AdjustedEBITDA
Adjusted EBITDA in the second quarter of 2025 was $60.7 million, compared to $8.3 million in the same period of 2024.
Liquidityand Capital Resources
As of June 30, 2025, the Company had cash and cash equivalents and digital assets of $211.4 million, compared to $168.1 million as of December 31, 2024. The increase was mainly due to the Company’s treasury management strategies, which have supported liquidity, and the appreciation in the value of BTC held by the Company during 2025.

Non-GAAPFinancial Measure
BitFuFu uses and considers Adjusted EBITDA, a non-GAAP financial measure, as a supplemental metrics in reviewing and evaluating its performance. BitFuFu defines Adjusted EBITDA as (1) GAAP net profit/loss, plus (2) adjustments to add back interest expense/(income), income tax expense/(benefit), depreciation and amortization, (3) share-based compensation and (4) adjustments for non-recurring items, if any. BitFuFu believes that this non-GAAP financial measure provides useful information to investors and others in understanding and evaluating the consolidated financial results in the same manner as its management and in comparing financial results across accounting periods. However, Non-GAAP financial measure is not defined under GAAP and are not presented in accordance with GAAP. Non-GAAP financial measure has limitations as analytical tools, which possibly do not reflect all items of expense that affect the Company’s operations. BitFuFu’s calculation of adjusted EBITDA may be different from the calculation methods of other companies, and therefore, the comparability of such measure may be limited. In addition, this non-GAAP financial measure adjusts for the impact of items that BitFuFu does not consider indicative of the operational performance of its business and should not be considered in isolation or construed as an alternative to net profit/loss or any other measure of performance or as an indicator of its future performance. The presentation of this non-GAAP financial measure is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with GAAP.
For more information on the non-GAAP financial measure, please see the table captioned “Unaudited Reconciliation of GAAP and non-GAAPResults” set forth at the end of this release. BitFuFu encourages you to review its financial information in its entirety and not rely on a single financial measure.
