Abpro Holdings, Inc. Receives Non-Compliance Notice from Nasdaq As previously disclosed, on January 28, 2026, Anthony D. Eisenberg notified the Board of Directors (the Board") of Abpro Holdings, Inc. (the Company") of his resignation from the Board and all committees thereof. On January 30, 2026, Sooyoung Lee notified the Board of his resignation from the Board and all committees thereof. Following these resignations, the Board has initiated a process to identify and appoint qualified independent directors to fill the resulting vacancies and to satisfy the applicable requirements of The Nasdaq Stock Market (Nasdaq"). On February 5, 2026, the Company received written notice from Nasdaq stating that, as a result of the resignations described above, the Company is no longer in compliance with Nasdaq Listing Rule 5605(b)(1), which requires a majority of the Board to be comprised of independent directors as defined in Nasdaq Listing Rule 5605(a)(2), and Nasdaq Listing Rule 5605(c)(2), which requires the audit committee of the Board (the Audit Committee") to consist of at least three members, each of whom is an independent director under the Nasdaq Listing Rules and meets the heightened independence standards applicable to audit committee members. Furthermore, the Company is not eligible for the cure period provided under Nasdaq Listing Rules 5605(b)(1)(A) and 5605(c)(4) because there is more than one vacancy on the Board and the Audit Committee. Accordingly, the Company's noncompliance with Nasdaq Listing Rules 5605(b)(1)(A) and 5605(c)(4) constitutes additional bases for delisting the Company's securities from Nasdaq. The notice further stated that the Nasdaq Hearings Panel (the Panel") will consider these additional deficiencies in connection with its determination regarding the Company's continued listing on The Nasdaq Capital Market and required the Company to submit its views with respect to these matters to the Panel in writing no later than February 12, 2026.

The notice provides that consistent with Nasdaq Listing Rule 5605(d)(4), the Company has a cure period to regain compliance, which extends until (1) the earlier of the Company's next annual shareholders' meeting or January 30, 2027; or (2) if the next annual shareholders' meeting is held before July 29, 2026, then the Company must evidence compliance no later than July 29, 2026. The Company intends to appoint qualified replacements to fill the vacancies on its Compensation Committee who satisfy the applicable requirements of the Nasdaq Listing Rules prior to the expiration of the applicable cure period. Neither of the Nasdaq notices has an immediate effect on the listing of the Company's common stock or warrants on Nasdaq. However, there can be no assurance that the Panel will grant the Company's request for continued listing or that the Company will be able to regain compliance with the applicable Nasdaq Listing Rules within the required time periods. 공시 • Jan 24

Abpro Holdings, Inc. and Celltrion, Inc. Announce U.S. FDA IND Clearance for Lead Multispecific Antibody Cancer Candidate ABP-102 / CT-P72 Abpro Holdings, Inc. announced, together with its co-development partner Celltrion, Inc., that the U.S. Food and Drug Administration (FDA) has cleared the Investigational New Drug (IND) application for ABP-102 /CT-P72, Abpro's lead multispecific antibody oncology program. The IND clearance enables the initiation of a Phase 1 clinical trial evaluating the safety, tolerability, pharmacokinetics, and preliminary efficacy of ABP-102 /CT-P72 in patients with HER2-positive solid tumors. The Phase 1 clinical study will be led by Celltrion as part of the ongoing joint strategic collaboration to ensure the robust progression of the ABP-102 /CT -P72 program. ABP-102 /CT the company is a multispecific HER2 x CD3 T-cell engager engineered to selectively target HER2-overexpressing tumor cells while engaging cytotoxic T cells, with optimized binding designed to enhance tumor selectivity and limit activity in normal HER2-low tissues. This design is intended to direct immune activity toward cancer cells while seeking to minimize damage to healthy tissue, addressing a key safety challenge that has limited the use of T-cell engagers in solid tumors. In preclinical studies, ABP-102 /CT/CT-P72 demonstrated robust antitumor activity in HER2-high tumor models, including dual xenograft models containing both HER2-high and HER2-low tumors, with selective efficacy for HER2-high tumors. The optimized CD3 binding of ABP-102/CT-P72, functionally linked with HER2-high selectivity, is intended to mitigate excessive immune activation and reduce the risk of cytokine release syndrome. Non-human primate toxicology studies showed the candidate was well tolerated at doses up to 80 mg/kg, with no significant adverse effects observed, supporting a differentiated therapeutic index. Additional preclinical evaluations demonstrated activity in tumor models representing resistance to existing HER2-directed therapies, highlighting the potential to address areas of unmet medical need. Preclinical data sets for ABP-102 /TC-P72 have been presented at major scientific meetings, including the 2025 Annual Meeting of the American Association for Cancer Research and the 2025 Annual Meeting of the Society for Immunotherapy of Cancer. Following IND clearance, Abpro and Celltrion plan to initiate a global Phase 1 clinical trial in the first half of 2026, subject to final site activation and regulatory processes. The study is expected to include dose-escalation and dose-expansion cohorts and will inform future clinical development strategies.
