INTRODUCTION

The following constitutes the Schedule 13D filed by the undersigned (the “Schedule 13D”). This Schedule 13D is being filed by Banyan Capital Holdings Co., Ltd., Banyan Partners Fund I, L.P. and Banyan Partners Ltd. to report the acquisition of ordinary shares of Huami Corporation, as described in Item 3 below.

The class of equity securities to which this Schedule 13D relates is Class A Ordinary Shares, par value US$0.0001 per share (the “Class A Ordinary Shares”) of Huami Corporation, an exempted company incorporated with limited liability under the laws of the Cayman Islands (the “Issuer” or “Huami”). The principal executive offices of the Issuer are located at Building H8, No. 2800, Chuangxin Road, Hefei, 230088, People’s Republic of China.

As of the date hereof, the Reporting Persons may be deemed to beneficially own an aggregate of 18,719,582 Class A Ordinary Shares, consisting of (i) 11,940,299 Class A Ordinary Shares issuable upon conversion of an aggregate of 11,940,299 Class B Ordinary Shares, par value US$0.0001 per share (the “Class B Ordinary Shares”) that were acquired by Banyan Holdings prior to the Issuer’s initial public offering (the “IPO”) of American Depositary Shares (“ADSs”) representing Class A Ordinary Shares and (ii) 6,779,283 Class A Ordinary Shares issuable upon conversion of 6,779,283 Class B Ordinary Shares issued to Banyan Holdings immediately prior to the completion of the IPO in consideration of its waiver of the conditions of qualified initial public offering as provided in the Shareholders Agreement (as defined below), as further discussed in Item 6 below. The IPO closed on February 12, 2018.

The 11,940,299 Class B Ordinary Shares acquired prior to the IPO were acquired upon the automatic conversion of 11,940,299 shares of Series B-2 preferred shares at the closing of the IPO. These Series B-2 preferred shares were purchased for US$1.67 per share.

The funds used by Banyan Holdings to acquire the securities described above were obtained from working capital contributed by its shareholders.

Banyan Holdings acquired the Class B Ordinary Shares for investment purposes. Except as set forth herein and except that the Reporting Persons or any of their affiliates may, from time to time or at any time, subject to market conditions and other factors, purchase additional ordinary shares of the Issuer in the open market, in privately negotiated transactions or otherwise, or sell at any time all or a portion of the ordinary shares of the Issuer now owned (including the Class A Ordinary Shares issuable upon conversion of the Class B Ordinary Shares owned by Banyan Holdings) or hereafter acquired by them in the open market, in privately negotiated transactions or otherwise, as of the date of this Schedule 13D, none of the Reporting Persons or, to the knowledge of the Reporting Persons, the Listed Persons has any present plans which relate to or would result in:

Bin Yue, the sole director of Banyan Holdings, has served on the board of directors of the Issuer since April 2015. As a director of the Issuer, Mr. Yue may have influence over the corporate activities of the Issuer, including activities which may relate to the transactions described in clauses (a) through (j) of this Item 4.

Each of the Reporting Persons may be deemed to beneficially own 31.9% of Class A Ordinary Shares, which is calculated based on 40,000,000 outstanding Class A Ordinary Shares, as reported in the Issuer’s Prospectus dated February 7, 2018 and filed with the Securities and Exchange Commission on February 9, 2018 (the “IPO Prospectus”), plus 18,719,582 Class A Ordinary Shares issuable upon conversion of the Class B Ordinary Shares beneficially owned by the Reporting Persons. Each of the Reporting Persons may be deemed to beneficially own7.9% of the total ordinary shares outstanding, which percentages are calculated based on 40,000,000 outstanding Class A Ordinary Shares and 197,736,467 outstanding Class B Ordinary Shares, as reported in the IPO Prospectus. Holders of Class A Ordinary Shares are entitled to one vote per share, while holders of Class B Ordinary Shares are entitled to ten votes per share. Accordingly, and based on the foregoing, the Class B Ordinary Shares beneficially owned by the Reporting Persons represent approximately 9.3% of the aggregate voting power of the total issued and outstanding ordinary shares of the Issuer.

To the knowledge of the Reporting Persons, Xiang Gao has sole voting and dispositive power over the ADSs beneficially owned by him.

Shareholders Agreement

Banyan Holdings and certain other shareholders (collectively, the “Holders”) of the Issuer entered into a Shareholders Agreement dated April 29, 2015 (the “Shareholders Agreement”) with the Issuer. The Shareholders Agreement provided for certain special rights, including right of first refusal, co-sale rights, preemptive rights and contained provisions governing the board of directors and other corporate governance matters. The Shareholders Agreement provided that those special rights, as well as the corporate governance provisions, would automatically terminate upon the completion of a qualified initial public offering. Certain shareholders, including Banyan Holdings, received Class B Ordinary Shares immediately prior to the completion of the IPO in consideration of their waiver of this condition of a qualified initial public offering. Accordingly, those special rights, as well as the corporate governance provisions, automatically terminated upon the completion of the IPO. However, the Shareholders Agreement also provides for certain registration rights, which have not been terminated and are discussed further below.

Demand Registration Rights

At any time after the earlier of (i) April 29, 2020 or (ii) one year following the taking effect of a registration statement for a qualified initial public offering, holders of at least 50% of the registrable securities (including preferred shares and ordinary shares issued on conversion of preferred shares) then outstanding have the right to demand that the Issuer files a registration statement covering at least 20% (or any lesser percentage if the anticipated gross proceeds to the Issuer from such proposed offering would exceed US$5 million) of the registrable securities. The Issuer has the right to defer filing of a registration statement for a period of not more than 90 days after the receipt of the request of the initiating holders if the Issuer furnishes to the holders requesting registration a certificate signed by its president or chief executive officer stating that in the good faith judgment of its board of directors, it would be materially detrimental to the Issuer and its shareholders for such registration statement to be filed at such time. However, the Issuer cannot exercise the deferral right more than once in any twelve-month period. The Issuer is obligated to effect no more than two demand registrations, other than demand registration to be effected pursuant to registration statement on Form F-3, for which an unlimited number of demand registrations shall be permitted.

Piggyback Registration Rights

If the Issuer proposes to file a registration statement for a public offering of its securities, it must offer its shareholders an opportunity to include in the registration all or any part of the registrable securities held by such holders. If the managing underwriters of any underwritten offering determine in good faith that marketing factors require a limitation of the number of shares to be underwritten, and the number of shares that may be included in the registration and the underwriting shall be allocated first to the Issuer, second to each of the holders requesting for the inclusion of their registrable securities on a pro rata basis, and third to holders of other securities of the Issuer.

Form F-3 Registration Rights

The Issuer’s shareholders may request in writing for the Issuer to file an unlimited number of registration statements on Form F-3. The Issuer shall effect the registration of the securities on Form F-3 as soon as practicable, except in certain circumstances.

Expenses of Registration

The Issuer will bear all registration expenses, other than underwriting discounts and selling commissions, and fees for special counsel of the holders participating in such registration, incurred in connection with any demand, piggyback or Form F-3 registration.

Termination of Registration Rights

The shareholders’ registration rights will terminate (i) on the fifth anniversary of a qualified initial public offering, and (ii) with respect to any shareholder, when the registrable securities proposed to be sold by such shareholder may then be sold without registration in any 90-day period pursuant to Rule 144 under the Securities Act.

The description of the Shareholders Agreement contained herein is qualified in its entirety by reference to Exhibit A, which exhibit is incorporated herein by reference.

Lock-Up Agreement

Banyan Holdings, along with all of the Issuer’s directors (including Mr. Yue), executive officers and stockholders, have agreed with the underwriters for the IPO that, for a period of 180 days after February 7, 2018 and subject to specified exceptions, it will not, without the prior written consent of the representatives of the underwriters, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer or dispose of, directly or indirectly, any ordinary shares, ADSs or any securities convertible into or exercisable or exchangeable for ordinary shares or ADSs (other than the grant of share-based awards pursuant to employee share incentive plans existing on February 7, 2018 provided that such awards are not exercisable within the restricted period and each such grantee signs a lock-up agreement) and will not enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of ordinary shares or ADSs. Without the prior written consent of the representatives on behalf of the underwriters, Banyan Holdings, along with all others party to the lock-up agreement, will not, during the restricted period, make any demand for, or exercise any right with respect to, the registration of any ordinary shares, ADSs or any security convertible into or exercisable or exchangeable for ordinary shares or ADSs.

Other than as described in this Schedule 13D, to the knowledge of the Reporting Persons, there are no other contracts, arrangements, understandings or relationships (legal or otherwise) among the persons named in Item 2 and between such persons and any person with respect to any securities of the Issuer.

The description of the lock-up agreement contained herein is qualified in its entirety by reference to Exhibit B, which exhibit is incorporated herein by reference.
