Exhibit 4.6

STOCK PURCHASE AGREEMENT

STOCK PURCHASE AGREEMENT dated as of March 24, 2026 among Opera Limited (“Company”), and Hong Kong Kunlun Tech Holding Limited (“Seller”).

WITNESSETH:

WHEREAS, the Company is authorized to purchase from time to time its publicly traded ADSs and ordinary shares (collectively, “Shares”) pursuant to a share repurchase program authorized by the Board of Directors of the Company on February 26, 2026;

WHEREAS, Seller is the direct beneficial owner of Shares of the Company;

WHEREAS Company wishes to buy and Seller wishes to sell a number of Shares that would represent a pro-rata repurchase between ADS purchased in the open market and Shares purchased from Seller based on the then-current distribution of ownership, such that purchases under the Company’s share repurchase program do not affect the ownership distribution between Seller and public market investors in the aggregate; and

WHEREAS in consideration of the above recitals and of the mutual agreements and covenants contained in this Agreement, the Company and the Sellers intending to be bound legally, each agree as follows:

ARTICLE 1

Section 1.1. Definitions. (a) The following terms, as used herein, have the following meanings:

“Applicable Quarter” means the period starting on and including the 16th day of the third month of each calendar quarter and continuing until the 15th day of the third month of the subsequent calendar quarter in which the Company purchases Shares pursuant to the Program; provided, however, that Applicable Quarter shall also include such shorter period as may exist in the event that the Program is terminated or concluded.

“Average Price” means, for any Applicable Quarter, the average price, rounded to four decimal points, at which the Company purchased Shares during the Applicable Quarter pursuant to the Program in open market purchases, calculated as (a) the total purchase price paid by the Company (excluding commissions) for Shares purchased pursuant to the Program in open market purchases during such Applicable Quarter divided by (b) the total number of Shares purchased by the Company pursuant to the Program in open market purchases during such Applicable Quarter; provided that if the Agreement has been terminated in accordance with Section 7.1, the Average Price for any Closing thereafter shall be calculated only through the day immediately prior to the termination date of the Agreement. For the avoidance of doubt, Shares acquired in “open market purchases” shall not include the Acquired Shares.

“Business Day” means (a) for purposes of determining the date of a Closing or Closing Notice, a day on which banks are not required or authorized by law to close in New York City and (b) for all other purposes under this Agreement, a day on which the Nasdaq Stock Market is open for trading.

“Dividend Adjusted Average Price” means, the price per Share calculated in accordance with the formula and methodology set forth in Annex A.

“Ex-Dividend Date” means the date that is one trading day prior to the record date which has been established in connection with the declaration of a dividend in respect of the Acquired Shares or such other date as may be established with respect to the Shares as an “ex-dividend” date by the Nasdaq Stock Market.

“Lien” means, with respect to any property or asset, any mortgage, lien, pledge, charge, security interest or other encumbrance of any kind in respect of such property or asset.

“Person” means an individual, corporation, partnership, limited liability company, association, trust or other entity or organization, including a government or political subdivision or an agency or instrumentality thereof.

“Program” means the share repurchase program approved on February 26, 2026, authorizing the Company to purchase from time to time Shares up to a maximum aggregate amount of $300 million.

(b) For purposes of the definitions of “Average Price” and “Daily Average Price,” Shares purchased by the Company pursuant to the Program shall be deemed to have been purchased on the trade date with respect to such Shares and not the day on which such trade settles.

ARTICLE 2

Purchase and Sale

Section 2.1. Purchase and Sale. Upon the terms and subject to the conditions of this Agreement, Seller agrees to sell, transfer, assign and deliver to the Company, and the Company agrees to purchase from Seller, with respect to each Applicable Quarter, a number of Shares at each Closing calculated in accordance with Annex A hereto (the Shares acquired from Seller, the “Acquired Shares”). In the event that the Agreement is terminated pursuant to Section 7.1, the day immediately prior to the termination date will be deemed to be the last day of the Applicable Quarter.

Section 2.2. Purchase Price. The aggregate purchase price for the Acquired Shares at each Closing (the “Purchase Price”) shall be equal to the product of (i) the aggregate number of Acquired Shares to be purchased at such Closing multiplied by (ii) the Dividend Adjusted Average Price. The parties acknowledge and agree that the Dividend Adjusted Average Price is intended to ensure that the Seller receives the same economic consideration per Share as if the Acquired Shares had been repurchased by the Company concurrently, and in the same pro rata proportion, as the ADSs repurchased in the open market during the Applicable Quarter. Accordingly, the Dividend Adjusted Average Price shall be calculated to neutralize the impact of any dividends by adjusting the daily volume-weighted average price of ADSs repurchased prior to an Ex-Dividend Date, as further detailed in Annex A. The Purchase Price shall be paid as provided in Section 2.3.

Section 2.3. Reporting & Payment. Within five Business Days after the end of each Applicable Quarter, the Company shall deliver to Seller a notice (each, a “Closing Notice”) setting forth (i) the number of Acquired Shares to be purchased by the Company from Seller pursuant to Section 2.1, (ii) the Purchase Price and (iii) details of the calculation of the Purchase Price sufficient to allow Seller to reproduce the calculation of the Purchase Price. Subject to the satisfaction or waiver by Seller and the Company of the conditions set forth in Article 6, each closing of the purchase and sale of the Acquired Shares hereunder shall take place automatically on the third Business Day before the end of the calendar quarter immediately following each Applicable Quarter.

At each Closing: (a) The Company shall deliver to Seller the Purchase Price by wire transfer in accordance with the payment instructions provided to the Company from time to time by Seller; and (b) the Company shall update the register of members to reflect the delivery Seller of the Acquired Shares (and the Seller shall cooperate in providing any required signatures or confirmations needed to effect such update) and the Seller shall thereafter promptly deliver any certificates representing the Acquired Shares to the Company or its designee.

ANNEX A

ACQUIRED SHARES CALCULATION

Quantity of Acquired Shares

The number of Acquired Shares to be purchased from Seller at each Closing shall be equal to:

multiplied by

provided that such number of Acquired Shares for the Applicable Quarter shall be rounded to the nearest whole Acquired Share, and

provided that in the event the Seller’s ownership percentage changes during an Applicable Quarter, for reasons other than the temporary effect of the Company’s purchases in the open market in accordance with this Agreement, the calculation shall be performed separately for periods prior to and subsequent to such change.

For purposes of the Acquired Shares calculation, Shares purchased in the open market by the Company pursuant to the Program shall be deemed to have been purchased on the trade date with respect to such Shares and not the day on which such trade settles.

Purchase Price

The Purchase Price for the Acquired Shares shall be determined on a quarterly basis to ensure economic parity with the Company’s open-market activity. The calculation shall be performed as follows:

Qpre: Total Shares repurchased on trading days occurring prior to the Ex-Dividend Date.

Qpost: Total Shares repurchased on trading days occurring on or after the Ex-Dividend Date.

VWAPpre: The volume-weighted average price of all Shares repurchased during the Qpre period.

VWAPpost: The volume-weighted average price of all Shares repurchased during the Qpost period.
