“We continue to execute well across our pipeline, with initial clinical data on track for both of our pan-RAS(ON) inhibitor-based assets in 2027,” said Yang Lu, CEO and Chairman of Adlai Nortye. “In alignment with our goal of rapidly bringing a solution to cancer patients in the U.S. and globally, we are advancing our globalization strategy by expanding our clinical development, strategic, and operational capabilities in the United States and Singapore. This expansion will help to accelerate our clinical pipeline progress and strengthen our clinical operations to support our RAS program development. We believe these efforts will support the efficient global development of our pipeline and position the Company for long-term growth.”

Corporate Highlights

Key Upcoming Milestones

First Half Unaudited Financial Results

The consolidated financial statements of the Company are prepared in accordance with IFRS as issued by the International Accounting Standards Board (IASB). The consolidated financial statements are presented in US dollars, the Company’s functional and presentation currency.

As of June 30, 2026, cash and cash equivalents, together with short-term investments at amortized cost, amounted to US$231.9 million, compared with US$8.1 million as of December 31, 2025.

Net cash used in operating activities was US$15.4 million for the six months ended June 30, 2026, compared with US$15.1 million for the six months ended June 30, 2025.

Revenue increased to US$13.1 million for the six months ended June 30, 2026, from nil for the six months ended June 30, 2025, and was entirely attributable to revenue recognized under the Company’s exclusive license agreement with Jiangsu Aosaikang Pharmaceutical Co., Ltd. relating to AN9025, primarily in connection with upfront payments and development milestone achievements.

Research and development expenses decreased by 4% from US$15.2 million for the six months ended June 30, 2025 to US$14.6 million for the six months ended June 30, 2026, primarily due to lower preclinical development costs, as most of the Company’s major research and development programs remained in early-stage development and had not yet advanced into later-stage clinical trials.

General and administrative expenses increased by 43.1% from US$4.1 million for the six months ended June 30, 2025 to US$5.8 million for the six months ended June 30, 2026. The increase was primarily attributable to higher share-based compensation expense associated with the vesting of certain stock options.

Other gains and expenses, net, decreased by 37.1% from US$1.5 million for the six months ended June 30, 2025 to US$0.9 million for the six months ended June 30, 2026, primarily due to a reduction in government grants recognized during the period.

For the reasons described above, the Company’s net loss decreased by 70.9% to US$5.3 million for the six months ended June 30, 2026, from US$18.3 million for the six months ended June 30, 2025.
