As disclosed in our Form 6-K filed on March 31, 2025, onMarch 31, 2025, Apollomics Inc. (“Apollomics” or the “Company”) announced that it had entered into an agreement (the “Agreement”) for the development and commercialization in Asia (excluding mainland China, HongKong and Macau) of vebreltinib, Apollomics’ proprietary c-Met inhibitor, in combination with an EGFR inhibitor (“EGFRi”) for the treatment of non-smallcell lung cancer (“NSCLC”) and other tumor types with LaunXP International Co., Ltd. (“LaunXP”), an affiliate of LaunXP Biomedical Co., Ltd. (TWO: 6876). Under the terms of the Agreement, Apollomics is to receive upfront paymentstotaling $10 million within 60 days of the date of the Agreement.

As of the date of this Form 6-K,$1.3 million of the $10 million upfront payment due under the Agreement has been paid by LaunXP. While the Company has continued to collaborate with LaunXP, the Company notified LaunXP that it has failed to cure its breach within the cureperiod permitted under the Agreement and that the Company plans to take appropriate actions to preserve and enforce its rights and to pursue available remedies. In response to the Company’s notice, LaunXP notified the Company that it believesit is not in breach of the Agreement and that the Company has not satisfied its obligations under the Agreement. The parties are actively engaged in discussions to resolve the matter. The Company cannot give any assurance that it will receive any ofthe $8.7 million owed by LaunXP or, if paid in full or in part, as to when any such payments will be received. LaunXP’s continued failure to pay the remainder of the $10 million upfront fee will have a material adverse effect on theCompany’s liquidity, financial condition and results of operations, and may render the Company insolvent and unable to sustain its operations and continue as a going concern.

As of June 30, 2025, the Company’s cash and cash equivalents totaled $2.1 million, of which $1.0 million was held outside of China. Asdisclosed in our 20-F filed on April 2, 2025, the Company’s estimates of future liquidity through December 31, 2025 are contingent upon receipt of the $10 million upfront payment fromLaunXP.

The information in this Form 6-K regarding LaunXP’s breach of its obligations under the Agreement isincorporated by reference into the Company’s registration statements under the Securities Act, including its registration statements on Form S-8 (FileNo. 333-272559) and Form F-3 (File Nos. 333-278430, 333-278431 and 333-279549), and shall be a part thereof, to the extent not superseded by documents or reports subsequently filed or furnished.
