Amber International Holding Limited Accelerates Specialized AI Agent Transformation as Q2 Revenue Grows 38.8% Quarter-over-Quarter and Profitability Turns Positive

Singapore, September 3, 2026 – Amber International Holding Limited (Nasdaq: AMBR) (“Amber International”, “we,” “us,” or the “Company”) today announced Second Quarter 2026 Unaudited Financial Results.

Management Commentary

Michael Wu, Chairman and Chief Executive Officer of Amber International, commented:

“The second quarter was a strong one for us. Revenue reached US$13.9 million, up 38.8% quarter-over-quarter, with gross margin expanding to 79.5%. Operating income and Adjusted EBITDA both turned positive. These results are the first evidence of the strategic direction we are taking.

Two days ago in Hong Kong, we introduced the new AMBR: a company that builds specialized AI agents. This is a deliberate pivot. We were a digital wealth management business; we are becoming a technology company. We are doing so from a position of strength, not as a reaction.

As of this week, we have two agents in the market. Ambre is our consumer agent for personal finance. It delivers the portfolio analysis, signals, monitoring and alerts that relationship managers have long provided to high-net-worth clients, but makes them available more broadly. It works across users’ existing exchange and brokerage accounts and does not place orders — when a user decides to act, they are connected to our expert team. Ambre is currently available by invitation, starting with Amber Premium’s verified client base.

MIA is our marketing agent and the proof that this model produces revenue. Built and scaled inside our wholly-owned marketing businesses, MIA already runs a substantial share of day-to-day campaign operations for more than a hundred enterprise customers. It is now also available as a direct product.

Ambre and MIA are the first two agents, not the full portfolio. Additional agents and the financial framework for the transition will be presented at our Investor Day, which we now expect to hold before year-end. Until then, our priority is disciplined execution on what we have just launched.”

Vicky Wang, President of Amber International, said: “Earlier this week, on September 1, we officially unveiled the new AMBR, focused on building specialized AI agents for high-value, high-stakes use cases. The initial response from clients, partners and the market has been encouraging.

Users want more than another general-purpose AI interface — they want intelligence that understands their context and can help them take action. This is where AMBR has a differentiated foundation: deep domain expertise, trusted financial infrastructure, and experience serving sophisticated users.

Our flagship product, Ambre, applies this approach to personal finance by building a holistic view of the user’s assets and priorities, identifying the signals that matter, and helping users act on them. We are also advancing MIA for growth and marketing workflows. Together, they demonstrate our thesis that the next generation of AI products will move from answering questions to understanding intent and executing complex workflows.

We look forward to sharing more as we expand Ambre, MIA and additional specialized agents.”

Second Quarter and First Half 2026 Highlights

Business Developments and Strategic Updates

In the second quarter, the Company advanced its strategic repositioning as a builder of specialized AI agents.

On September 1, the Company formally unveiled the new AMBR brand and introduced its next chapter, focused on building specialized AI agents for high-value, high-stakes use cases. Two agents are now in market:

Ambre, the flagship consumer agent for personal finance, is designed to build a holistic understanding of a user’s assets, priorities and financial context, identify the signals that matter most, and increasingly help users monitor and act on those insights. It works across existing exchange and brokerage accounts and does not place orders. Ambre is currently available by invitation, starting with Amber Premium’s verified client base.

MIA, the specialized agent for growth and marketing workflows, continues to operate at commercial scale within the Company’s wholly-owned marketing businesses and is now also available as a direct product.

Together, Ambre and MIA demonstrate the Company’s thesis that the next generation of AI products will move from answering questions to understanding intent, maintaining context and executing complex workflows on behalf of users.

Agentic revenue reached US$7.4 million in the quarter, including the initial contribution from A-MM. This higher-margin mix supported the expansion of gross margin to 79.5% and the return to positive operating income and Adjusted EBITDA.

The Company expects to provide a fuller view of its agent portfolio and the financial framework for the transition at its Investor Day, anticipated before year-end. Until then, the priority is disciplined execution on the products already in the market.

Share Repurchase Program

On November 26, 2025, the Company announced a share repurchase program authorizing the purchase of up to US$50.0 million of its ADSs over a 12-month period commencing December 1, 2025. As of June 30, 2026, the Company had repurchased a total of 2,636,910 ADSs under this program for an aggregate consideration of approximately US$5.8 million. As of June 30, 2026, approximately US$44.2 million remained available for future repurchases under the program, providing significant capacity for opportunistic repurchases alongside continued growth investment.

Second Quarter 2026 Financial Results Summary

The following table sets forth the key financial metrics of the Company for the periods indicated.

* Certain operations were classified as held-for-sale starting from the third quarter of 2025, and we completed one of the disposals in October 2025. The disposed business was deconsolidated from the Company upon the respective disposal and the results of the held-for-sale and disposed businesses are reflected in the consolidated financial statements as discontinued operations accordingly.

Revenue for the second quarter of 2026 increased 38.8% quarter-over-quarter from US$10.0 million in the prior quarter to US$13.9 million. The addition of revenue from A-MM this quarter further broadened the Company’s revenue base, alongside the growth in institutional-grade wealth management platforms.

¹ Beginning in the second quarter of 2026, the Company introduced (i) “Digital Assets Platform Revenue,” comprising the revenue from Wealth Management Solutions, Execution Solutions, and Payment Solutions, and (ii) “Agentic Revenue”, comprising the revenue generated from A-MM (Agentic Market Making) and Marketing and Enterprise Solutions to better reflect the evolution of its AI-enabled business model. Comparative period information has been conformed to the current presentation. Any discrepancies on announcement between the amounts identified as total amounts and the sum of the amounts listed therein are due to rounding.

² For more details on these non-GAAP financial measures, please see the tables captioned "Unaudited Reconciliations of GAAP and Non-GAAP Results" set forth at the end of this press release.

Combined revenue from Digital Assets Platform and A-MM reached US$10.1 million in the second quarter of 2026, exceeding the Company's previously communicated Amber Premium revenue outlook of US$9.0 million to US$10.0 million, which was provided prior to the introduction of A-MM as a new revenue stream under Amber Premium. Digital Assets Platform Revenue contributed US$6.6 million, and A-MM contributed US$3.5 million revenue during the quarter.

Gross profit increased to US$11.1 million in the second quarter of 2026 from US$6.8 million last quarter, while gross profit margin reached 79.5% in the second quarter of 2026, from 67.7% last quarter. These improvements were driven by a more favorable higher-margin business mix, including the contributions from our new agentic revenue from A-MM and the core Wealth Management Solutions.

Total operating expenses remained stable at US$10.0 million in the second quarter of 2026. The disciplined cost management demonstrated the scalability of our operations through the integration of AI capabilities across the business and the ongoing transition of our business to an AI-driven operating model.

Operating income improved to US$1.0 million in the second quarter of 2026, turning positive from an operating loss of US$3.2 million last quarter, contributed by stronger gross profit performance and new higher-margin A-MM business.

Other gains, net were US$0.4 million in the second quarter of 2026, versus US$0.6 million other losses, net last quarter. The results in the second quarter of 2026 mainly benefited from a more favorable unrealized fair value change of crypto assets loan receivables and digital assets.

Net income from continuing operations achieved US$1.5 million in the second quarter of 2026, compared to net loss of US$3.7 million last quarter.

Adjusted EBITDA from continuing operations strengthened to US$1.9 million profitability in the second quarter of 2026, from a loss of US$3.2 million last quarter.

Adjusted net income from continuing operations was US$1.5 million, improved from adjusted net loss of US$3.5 million last quarter.

As of June 30, 2026, the Company had cash and cash equivalents, time deposits and restricted cash of US$34.2 million, compared to US$33.9 million as of December 31, 2025.

Withdrawal of Outlook

In view of the Company's strategic transition towards an agentic AI company, the management has determined that the previously issued financial guidance is no longer an appropriate measure of the Company's future performance. Accordingly, we are withdrawing our financial guidance while we evaluate the financial impact of the new business initiatives. The Company expects to provide updated guidance once sufficient operating history and forecasting visibility have been established.

Non-GAAP Financial Measures

The Company uses adjusted EBITDA from continuing operations, adjusted net income/(loss) from continuing operations, and diluted adjusted net income/(loss) from continuing operations per ADS, each a non-GAAP financial measure, in evaluating the Company's operating results and for financial and operational decision-making purposes. The Company believes that adjusted EBITDA from continuing operations, adjusted net income/(loss) from continuing operations, and diluted adjusted net income/(loss) from continuing operations per ADS help identify underlying trends in the Company's business that could otherwise be distorted by the effect of the expenses and gains that the Company includes in net income/(loss). The Company believes that adjusted EBITDA from continuing operations and adjusted net income/(loss) from continuing operations provide useful information about the Company's operating results, enhance the overall understanding of the Company's past performance and future prospects, assess operating performance on a consistent basis, and allow for greater visibility with respect to key metrics used by the Company's management in its financial and operational decision-making.

Adjusted EBITDA from continuing operations, adjusted net income/(loss) from continuing operations, and diluted adjusted net income/(loss) from continuing operations per ADS should not be considered in isolation or construed as an alternative to net income/(loss) or any other measure of performance or as an indicator of the Company's operating performance. Investors are encouraged to review the historical non-GAAP financial measures to the most directly comparable GAAP measures. Adjusted EBITDA from continuing operations, adjusted net income/(loss) from continuing operations, and diluted adjusted net income/(loss) from continuing operations per ADS presented here may not be comparable to similarly titled measures presented by other companies. Other companies may calculate similarly titled measures differently, limiting their usefulness as comparative measures to the Company's data. The Company encourages investors and others to review the Company's financial information in its entirety and not rely on a single financial measure.

For more information on these non-GAAP financial measures, please see the table captioned “Unaudited Reconciliations of GAAP and Non-GAAP Results” set forth at the end of this press release.

These non-GAAP financial measures were presented with the most directly comparable GAAP financial measures together for facilitating a more comprehensive understanding of operating performance between periods.
