BIT Mining Attempts to Rebrand as SOLAI to Reflect Strategic Shift Toward the Solana Ecosystem

AKRON, Ohio, Aug 20, 2025 – BIT Mining Limited (NYSE: BTCM) (the “Company”), a leading technology-driven cryptocurrency company, today announced that it seeks to rebrand to SOLAI (NYSE: SLAI), a name that reflects the Company’s strategic transformation and commitment to building an on-chain intelligent financial infrastructure. The new brand identity underscores the Company’s evolution from a pure-play cryptocurrency miner into a broader digital assets company focused on next-generation blockchain infrastructure, decentralized finance, and smart contract innovation.

SOLAI—merging SOL (derived from the Latin for 'sun') with SOLANA's vision, empowered by AI—symbolizes our dual focus on high-performance blockchain systems and visionary innovation, embodying technological hope and sustainable scientific advancement.

“Becoming SOLAI marks the next chapter in our journey to providing the best value for our shareholders,” commented Bo Yu, the Chairman and Chief Operating Officer of the Company. “We will establish a global financial infrastructure powered by AI, driven by transparency, and optimized for capital efficiency. Beginning with the SOLANA ecosystem, our strategic foundation will seamlessly expand to other blockchain platforms, bridging innovation with real-world financial ecosystems.”

Since announcing its evolution beyond mining, the Company has steadily expanded its footprint in the Solana ecosystem. The Company recently launched a validator node on Solana and began staking the SOL it purchased as part of a broader $300 million ecosystem strategy. The rebrand builds on this momentum and signals the Company’s ambition to be a long-term contributor to the growth, decentralization, and resilience of the blockchain network.

The Company’s board of directors (the "Board") resolved to (i) change the Company's English name to "SOLAI Limited" (the "English Name Change"), subject to shareholders’ approval to be obtained at an extraordinary general meeting of shareholders (the "EGM"), and (ii) change the ticker symbol to "SLAI."

The EGM will be held at 428 South Seiberling Street, Akron, Ohio, US, on October 9, 2025 at 10:00 a.m., New York time.

Holders of record of the Company's ordinary shares and Class A preference shares at the close of business on August 25, 2025, New York time (the "Record Date") are entitled to receive notice of, and to attend and vote at, the EGM or any adjournment thereof. Holders of the Company's American Depositary Shares ("ADSs") who wish to exercise their voting rights for the underlying ordinary shares must act through Deutsche Bank Trust Company Americas, the depositary of the Company's ADS program.

Notice of the EGM, which sets forth the resolutions to be submitted for shareholder approval at the EGM will be made available on the Investor Relations section of the Company's website at https://ir.btcm.group/ on or around the Record Date. The Company filed its annual report on Form 20-F for the fiscal year ended December 31, 2024 with the U.S. Securities and Exchange Commission (the “SEC”) on April 29, 2025. Shareholders may obtain a copy of the Company’s annual report, free of charge, from the Company’s website at https://ir.btcm.group and on the SEC’s website at www.sec.gov, or by contacting BIT Mining Limited at 428 South Seiberling Street, Akron, Ohio, US, attention: Victor He, telephone: +1 (330) 676-2680, email: ir@btcm.group.

Holders of American Depositary Shares (“ADSs”) issued by Deutsche Bank Trust Company Americas and representing the Company’s Class A Ordinary Shares are not entitled to attend or vote at the EGM. These holders of ADSs will be able to instruct Deutsche Bank Trust Company Americas, the holder of record of such Class A Ordinary Shares (through a nominee), as to how to vote the Class A Ordinary Shares which are represented by such ADSs, and which Deutsche Bank Trust Company Americas, as depositary of the ADSs, will endeavor, to the extent practicable and legally permissible, to vote or cause to be voted at the EGM in accordance with the instructions which it has properly received from such ADS holders.

One or more shareholders holding in aggregate not less than one-third of the voting power of the Shares of the Company in issue carrying a right to vote at such meeting, present in person or by proxy or, if a corporation or other non-natural person, by its duly authorized representative or proxy and entitled to vote shall be a quorum for all purposes.

Voting and Solicitation

Each Class A Ordinary Share, Class B Ordinary Share and Class A Preference Share issued and outstanding as of the close of business on the Record Date is entitled to one vote, ten votes and 10,000 votes, respectively, on a poll. On a show of hands, every shareholder present in person and every person representing a shareholder by proxy shall each have one vote. A resolution put to the vote at the EGM will be decided on by a show of hands unless (before or on the declaration of the result of the show of hands) a poll is demanded by (i) the chairman of the EGM, or (ii) any one or more shareholders, holding at least one-tenth of the paid-up Shares given a right to vote at such meeting or one-tenth of the total voting rights entitled to vote at such meeting, present in person or by proxy or, in the case of a shareholder being a corporation or other non-natural person, by its duly authorized representative or by proxy.

Copies of solicitation materials will be furnished to all holders of Shares and ADSs of the Company, including banks, brokerage houses, fiduciaries and custodians holding in their names Shares or ADSs beneficially owned by others to forward to those beneficial owners.

Voting by Holders of Shares

When proxy forms are properly dated, executed and returned by holders of Shares, the Shares they represent will be voted by the proxy holder at the EGM, or at any adjournment thereof, in accordance with the instructions of the shareholder. If no specific instructions are given in such proxy forms, the proxy holder will vote in the discretion of such proxy holder and, where the chairman of the EGM is the proxy holder, he will vote in favor of the items set forth in the proxy form. The proxy holder will also vote in the discretion of such proxy holder on any other matters that may properly come before the EGM, or at any adjournment thereof. Abstentions by holders of Shares are not included in the determination of the number of Shares present and voting for the purposes of determining whether such resolution has been passed (but will be counted for the purposes of determining the quorum, as described above).

Voting by Holders of ADSs

As the holder of record for all the Class A Ordinary Shares represented by the ADSs (through a nominee), only Deutsche Bank Trust Company Americas may vote those Class A Ordinary Shares at the EGM.

We have requested Deutsche Bank Trust Company Americas, as depositary of the ADSs, to distribute to all owners of ADSs at the close of business on the Record Date this proxy statement, the accompanying notice of the EGM and an ADS voting card. Upon the timely receipt from an owner of record of ADSs of written voting instructions in the manner specified, Deutsche Bank Trust Company Americas will endeavor, to the extent practicable and legally permissible, to vote or cause to be voted the number of Class A Ordinary Shares represented by the ADSs in accordance with such voting instructions. Under the terms of the deposit agreement for the ADSs (the “Deposit Agreement”), Deutsche Bank Trust Company Americas will not vote or attempt to exercise the right to vote other than in accordance with such voting instructions or such deemed instructions as further described below.

There is no guarantee that holders of the ADSs or any such holder in particular will receive the notice described above with sufficient time to enable such holder to return any voting instructions to Deutsche Bank Trust Company Americas in a timely manner, in which case the Class A Ordinary Shares underlying your ADSs may not be voted in accordance with your wishes.

If (i) an ADS voting card is missing voting instructions, (ii) an ADS voting card is improperly completed or (iii) no ADS voting card is received by Deutsche Bank Trust Company Americas by 10 a.m. (New York City time), October 3, 2025, Deutsche Bank Trust Company Americas will deem such holder of ADSs to have instructed it to give a discretionary proxy to a person designated by the Company to vote the Class A Ordinary Shares represented by such holder’s ADSs, unless the Company has informed Deutsche Bank Trust Company Americas that such proxy should not be given, in accordance with the terms of the Deposit Agreement.

Revocability of Proxies and ADS Voting Cards

Any proxy given by a holder of Shares by means of a proxy form, and any voting instructions given by an ADS holder by means of an ADS voting card, pursuant to this solicitation may be revoked: (a) for holders of Shares or ADSs, by submitting a written notice of revocation or a fresh proxy form or ADS voting card, as the case may be, bearing a later date, which must be received no later than at least 48 hours before the time of the EGM, or (b) for holders of Shares only, by attending the EGM and voting in person.
