*(A company controlled through weighted voting rights and*

*incorporated in the Cayman Islands with limited liability)*

**(NYSE: NIO; HKEX: 9866; SGX: NIO)**

**Notice of Annual General Meeting**

to be held on June 24, 2026

(or any adjournment(s) or postponement(s) thereof)

**NOTICE IS HEREBY GIVEN** that an annual general meeting (the "**AGM**") of NIO Inc. (the "**Company**") will be held at 10:30 a.m., Beijing time, on June 24, 2026 at Building 19, No. 1355, Caobao Road, Minhang District, Shanghai, People's Republic of China, for the purposes of considering and, if thought fit, passing each of the following resolutions:

**AS** **ORDINARY RESOLUTIONS**

1. To re-elect
 Mr. Hai Wu as an independent director of the Company.

2. To
appoint PricewaterhouseCoopers and PricewaterhouseCoopers Zhong Tian LLP as the auditors of the Company to hold office until the conclusion
of the next annual general meeting of the Company and to authorize the Board to fix their remuneration for the year ending December 31,
2026.<sup>1</sup>

The passing of the above resolutions requires approval by the holders of the Class A ordinary shares of a par value of US$0.00025 each (the "**Class A Ordinary Shares**") and the Class C ordinary shares of a par value of US$0.00025 each (the "**Class C Ordinary Shares**," and together with the Class A Ordinary Shares, the "**Shares**") of the Company by a simple majority of the votes cast by the shareholders as, being entitled to do so, vote in person or by proxy at the AGM, on a one share one vote basis.

The quorum of the AGM shall be one or more members holding in aggregate at least one-third of all votes attaching to all issued shares of the Company, present in person or by proxy and entitled to vote at the AGM.

**SHARES RECORD DATE AND ADS RECORD DATE**

The Board has fixed the close of business on May 22, 2026 (Hong Kong time), as the record date (the "**Shares Record Date**") of Class A Ordinary Shares and Class C Ordinary Shares. Holders of record of the Shares (as of the Shares Record Date) are entitled to attend and vote at the AGM and any adjourned meeting thereof.

Holders of record of American Depositary Shares (the "**ADSs**") as of the close of business on May 22, 2026 (New York time) (the "**ADS Record Date**," together with the Shares Record Date, the "**Record Date**") will be able to instruct Deutsche Bank Trust Company Americas, the depositary of the ADSs, as to how to vote the Class A Ordinary Shares represented by such ADSs at the AGM.

<sup>1</sup> Taking into account the current scope and complexity of the audit work, the expected audit timetable, professional expertise and auditors' resources required, the estimated audit fee for the year ending December 31, 2026 is expected to be within the range of approximately RMB12.5 million to RMB14.5 million, which is exclusive of out-of-pocket expenses, tax and related surcharges. based on the assumption that there will be no material change in our operations, business plan, audit scope or applicable regulatory requirements, and no additional non-recurring audit work arising from any material transaction, acquisition or other similar event, during the year ending December 31, 2026.

Holders of Class A Ordinary Shares which are held through (either directly or through depository agents) securities accounts (the "**NIO CDP Depositors**") maintained with The Central Depository (Pte) Limited ("**CDP**") (Singapore) as of the close of business on the Shares Record Date may be appointed as CDP's proxy to attend and cast votes at the AGM, or provide instructions as to voting, or abstentions from voting to CDP. For further information, see "Attending the AGM."

**ATTENDING THE AGM**

Only holders of record of Shares as of the Shares Record Date are entitled to attend and vote at the AGM.

Holders of ADSs must give voting instructions to Deutsche Bank Trust Company Americas if they wish to exercise their voting rights for the underlying Class A Ordinary Shares.

NIO CDP Depositors who:

(a) wish
 to be appointed as CDP's proxy to attend and cast votes at the AGM; or

(b) do
 not wish to attend the AGM as CDP's proxy but wish to provide
 instructions as to voting, or abstentions from voting,

For the avoidance of doubt, NIO CDP Depositors who do not complete and return the AGM Depositor Proxy Form by 5:00 p.m., Singapore time, on June 17, 2026, will **<u>not</u>** be able to attend or vote at the AGM, or provide instructions as to voting, or abstentions from voting.

Part II If a Depositor(s) wishes to provide instructions to the Chairman as to voting or abstentions from voting, please indicate a "√" (or a particular number of shares, if preferred) in the appropriate box against each resolution how you wish the Chairman to vote. Depositors should specifically direct the Chairman on how they wish to vote for or vote against (or abstain from voting on) the resolution in Part II of this Depositor Proxy Form. If this Depositor Proxy Form is deposited without any indication as to how the Chairman shall vote in respect of any particular resolution, the Chairman may vote or abstain from voting at his/her discretion. If a Depositor(s) marks the abstain box for a particular resolution, he/she/it is directing the Chairman not to vote on that resolution and the votes will not be counted in computing the required majority when a poll is called. Part III If a Depositor(s) wishes to attend, speak and vote at the Annual General Meeting in person instead of providing instructions to the Chairman as to voting (or abstentions from voting), please indicate a "√" in the box in Part III. For the avoidance of doubt, a Depositor(s) should only complete either Part II (if the Depositor(s) wishes to provide instructions to the Chairman as to voting or abstentions from voting) OR Part III (if the Depositor(s) wishes to attend, speak and vote at the Annual General Meeting in person) of this Depositor Proxy Form. Where a Depositor(s) has completed both Part II and Part III of this Depositor Proxy Form, the Depositor(s) acknowledge(s) that the Chairman, and not the Depositor(s), will be appointed as CDP's proxy to attend, speak and vote at the Annual General Meeting. Part V If a Depositor(s) wishes to provide instructions to the Chairman as to voting or be appointed as CDP's proxy to attend and cast votes at the Annual General Meeting as CDP's proxy in person, Part V of this Depositor Proxy Form must be signed by the Depositor(s) or his/her/its attorney duly authorised in writing. In the case of joint Depositor(s), all joint Depositor(s) must sign Part V of this Depositor Proxy Form. If the Depositor(s) is a corporation, Part V of this Depositor Proxy Form must be executed under its common seal or under the hand of an officer or its attorney duly authorised in writing. The power of attorney appointing the attorney or other authority, or a notarially certified copy thereof, if any, under which Part V of this Depositor Proxy Form is signed, must (unless previously registered with the Company) be attached to this Depositor Proxy Form. This Depositor Proxy Form, duly completed, together with the abovementioned power of attorney appointing the attorney or other authority, or a notarially certified copy thereof, if applicable, must be deposited by the Depositor(s) in the following manner: (i) if submitted by post, by depositing the duly completed Depositor Proxy Form at the office of the Company's Singapore Share Transfer Agent, Boardroom Corporate & Advisory Services Pte. Ltd. at 1 Harbourfront Avenue, #14-07 Keppel Bay Tower, Singapore 098632; or (ii) if submitted electronically, by scanning and submitting the duly completed Depositor Proxy Form via email to the Company's Singapore Share Transfer Agent, Boardroom Corporate & Advisory Services Pte. Ltd., at srs.proxy@boardroomlimited.com, in either case, not later than June 17, 2026 at 5 p.m. (Singapore time). The Company shall be entitled to reject any Depositor Proxy Form which is incomplete, improperly completed or illegible or where the true intentions of the Depositor(s) are not ascertainable from the instructions of the Depositor(s) specified on any Depositor Proxy Form. It is the Depositors' responsibility to ensure that this Depositor Proxy Form is properly completed (including that it has been duly signed). Any decision to reject this Depositor Proxy Form on the grounds that it is incomplete, improperly completed or illegible will be final and binding and neither the Company, CDP nor Boardroom Corporate & Advisory Services Pte. Ltd. accepts any responsibility for the consequences of such a decision. In addition, the Company may, at its discretion, reject any Depositor Proxy Form lodged if a Depositor(s) is not shown to have shares entered against his/her/its name in the Depository Register, as supplied by CDP to the Company, as at the Shares Record Date. By submitting this Depositor Proxy Form, a Depositor of the Company (i) consents to the collection, use and disclosure of the Depositor's personal data by the Company (or its agents) for the purpose of the processing and administration by the Company (or its agents) of proxies appointed for the Annual General Meeting (including any adjournment thereof) and the preparation and compilation of the attendance lists, minutes and other documents relating to the Annual General Meeting (including any adjournment thereof), and in order for the Company (or its agents) to comply with any applicable laws, listing rules, regulations and/or guidelines.  |
