This registration statement on Form S-8 is filed pursuant to General Instruction E to Form S-8 for the purposes of registering an aggregate of 7,100,000 Class A ordinary shares of Amber International Holding Limited (the “Registrant”) that have been added to the award pool of the Post-IPO Share Incentive Plan. These 7,100,000 Class A ordinary shares are additional securities of the same class as other securities of the Company for which the S-8 Registration Statement was filed with the Commission on June 12, 2018 (file number: 333-225568) (the “Original S-8 Registration Statement”), and were not previously registered under the Original S-8 Registration Statement, the S-8 Registration Statement filed with the Commission on October 9, 2018 (file number: 333-227747), or the S-8 Registration Statement filed with the Commission on February 26, 2021 (file number: 333-253596) (the “Prior Registration Statements”).

Previously, an aggregate of 6,491,335 Class A ordinary shares of the Registrant were registered for issuance under the 2018 Share Incentive and the Post-IPO Share Incentive Plan pursuant to the Prior Registration Statements. In accordance with General Instruction E to Form S-8, the contents of the Prior Registration Statements are incorporated herein by reference, except as otherwise set forth herein.

On December 31, 2021, the board of directors of the Registrant approved an increase of 1,500,000 Class A ordinary shares (the “2021 Second Amendment”) to the award pool under the Post-IPO Share Incentive Plan. On May 16, 2025, the board of directors of the Registrant further amended the Post-IPO Share Incentive Plan by increasing 5,000,000 Class A ordinary shares to the award pool (the “2025 Amendment” and as amended, the “2025 Post-IPO Share Incentive Plan”). The aggregate of newly added 6,500,000 Class A ordinary shares are being registered on this registration statement.

Under the 2025 Post-IPO Share Incentive Plan, the maximum aggregate number of Class A ordinary shares available for all awards will initially be 11,000,000 Class A ordinary shares, plus an annual increase for each fiscal year of the Registrant during the term of this 2025 Post-IPO Share Incentive Plan commencing with the fiscal year beginning January 1, 2026, by an amount equal to (i) 0.5% of the total number of Class A shares issued and outstanding on the last day of the immediately preceding fiscal year, or (ii) such number of Shares as may be determined by the Board, the size of the award pool to be equitably adjusted in the event of any share dividend, subdivision, reclassification, recapitalization, split, reverse split, combination, consolidation or similar transactions (the “Evergreen Provision”).

Pursuant to the Evergreen Provision, the maximum aggregate number of shares which may be issued under the Post-IPO Share Incentive Plan increased by an aggregate of 600,000 Class A ordinary shares in 2021, 2022, 2023 and 2024. The newly added 600,000 Class A ordinary shares pursuant to the Evergreen Provision are being registered on this registration statement.
