Equity Capital Markets Analyst

Amber International adds a US$50 million buyback alongside ongoing growth investments.

Amber International Holding Limited has authorized a share repurchase program for up to US$50 million of its American depositary shares over the 12 months starting December 1, 2025. Buybacks of this size can reduce the public float and support per‑share metrics, but the actual effect depends on how many ADSs are ultimately repurchased and at what prices.

The company indicates it will execute repurchases via open market purchases, privately negotiated transactions, and block trades, following Rule 10b‑18 and Rule 10b5‑1 under the Exchange Act. This framework provides flexibility while staying within prescribed safe harbor and trading‑plan practices.

Management plans to fund the program using its cash balance and cash generated from operations, and states it does not expect the program to adversely affect existing business strategies, including AI‑driven technology, real world asset platform development, and broader market expansion. Subsequent disclosures can clarify the pace of repurchases and their interaction with capital needs.

Amber International Holding Limited (Nasdaq: AMBR) (“Amber International”, or the “Company”), a global leading digital wealth management platform and operating under the brand name “Amber Premium,” today announced that its board of directors has authorized a share repurchase program under which the Company may repurchase up to US$50 million worth of its outstanding American depositary shares (“ADSs”), each representing five Class A ordinary shares over the next 12 months starting from December 1, 2025.

“This share repurchase program reflects our Board’s confidence in Amber International’s business momentum and long-term growth trajectory,” said Michael Wu, Chairman and CEO. “Supported by a healthy balance sheet and disciplined capital allocation framework, we are positioned to return capital to shareholders while continuing to invest strategically in our AI-driven technology roadmap, Real World Asset platform development, and broader market expansion initiatives.”

Under the share repurchase program, the Company may repurchase its ADSs from time to time through open market transactions at prevailing market prices, privately negotiated transactions, block trades or any combination thereof. In addition, the Company will also effect repurchase transactions in compliance with Rule 10b-18 and Rule 10b5-1 as applicable under the Securities Exchange Act of 1934, as amended, and its insider trading policy. The number of ADSs repurchased and the timing of repurchases will depend on a number of factors, including, but not limited to, share price, trading volume and general market conditions, along with the Company’s working capital requirements and general business conditions. The Company’s board of directors will review the share repurchase program periodically, and may authorize adjustment of its terms and size. The Company plans to fund the repurchases from a combination of its cash balance and cash generated from its operations, and does not expect the repurchase program to adversely affect its existing business strategies.
