Nano Labs Announces Second Half of 2025 Financial Results

HANGZHOU, China, March 30, 2026 (GLOBE NEWSWIRE) -- Nano Labs Ltd (Nasdaq: NA) (“we,” the “Company” or “Nano Labs”), a leading Web 3.0 infrastructure and product solution provider and crypto treasury company today announced its unaudited financial results as of December 31, 2025 and for the six months ended December 31, 2025.

Second Half of 2025 Financial Summary

Mr. Jianping Kong, Chairman and Chief Executive Officer of the Company, commented: “2025 witnessed vigorous development in the Web3.0 industry. With the continuous improvement of the global crypto market environment, including the enhancement of crypto asset infrastructure and rising market participation, the crypto market and Web3.0-related sectors embraced a new phase of growth and opportunities.

Following a comprehensive and meticulous internal assessment of BNB’s strategic value and long-term prospects, we decided to take the lead in launching and continuously advancing the buildout of a BNB reserve. As of December 31, 2025, we held a total of 126,662 BNBs and a receivable for 3,338 BNBs collateral. By steadily increasing the BNB holdings, we have not only optimized our crypto asset allocation but also created favorable conditions for future business expansion and ecological collaboration.

In terms of capital operations, we successfully completed two rounds of financing in 2025, which provided strong support for the Company’s strategic transformation, the expansion of our crypto asset reserves, and the exploration of new business directions.

In March 2026, we officially launched our new-generation product — iPollo ClawPC A1 Mini, designed to support the Open Claw AI Agent system. Subsequently, we plan to introduce the Claw OS system and more hardware products to further extend the full-chain ecological services for AI Agents.

Meanwhile, to further enhance shareholder value and demonstrate the management’s confidence in the Company’s long-term development, we announced a share repurchase program of up to US$25.0 million in October 2025. This program has commenced and is expected to be implemented steadily over the long term.

Looking ahead, we will continue to closely monitor emerging industry trends and market dynamics. While maintaining stable operations, we will further advance our crypto asset strategic reserve and pursue broader industrial opportunities in the AI Agent ecosystem.”

Mr. Bing Chen, Chief Financial Officer of the Company, added: “For the second half of 2025, our net revenue increased by 18.1% from RMB15.9 million to RMB18.7 million (US$2.7 million). In addition, we successfully turned to a net income of RMB137.7 million (US$19.6 million) for the six months ended December 31, 2025, compared to a net loss of RMB60.4 million in the same period of 2024. Adhering to the principles of long-termism and prudent decision-making, our management will continue to monitor and capture emerging opportunities arising in the transformation from Web3.0 to Web4.0, with the goal of creating sustainable long-term value for the Company and all shareholders.”

Non-GAAP Financial Measures

In evaluating our business, we consider and use adjusted net income/(loss) as an additional non-GAAP measure to review and assess our operating performance. The presentation of the 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 U.S. GAAP. We define adjusted net income/(loss) as net income/(loss) excluding share-based compensation expense.

We present the non-GAAP financial measure because they are used by our management to evaluate our operating performance and formulate business plans. Non-GAAP financial measures enable our management to assess our operating results without considering the impact of non-cash charges and non-operating items. We also believe that the use of the non-GAAP measure facilitates investors’ assessment of our operating performance.

The non-GAAP financial measure is not defined under U.S. GAAP and is not presented in accordance with U.S. GAAP. The non-GAAP financial measure has limitations as analytical tools. One of the key limitations of using the non-GAAP financial measure is that they do not reflect all items of income and expense that affect our operations. Share-based compensation expenses have been and may continue to be incurred in our business and are not reflected in the presentation of adjusted net income/(loss). Further, the non-GAAP measure may differ from the non-GAAP information used by other companies, including peer companies, and therefore their comparability may be limited.
