Corestemchemon Advances Toward Als Stem Cell Commercialization with Regulatory Progress in Korea and Nsf-Backed U.S. Expansion CorestemChemon is entering a critical late-stage phase in the commercialization of its ALS stem cell therapy, Neuronata-R. The company attributes this momentum to advanced domestic regulatory review in Korea, entry into an NSF-supported regenerative medicine ecosystem in the United States, secured commercialization capital, and a sizable open-market share purchase by the CEO. In Korea, Neuronata-R is undergoing a product license modification review by the Ministry of Food and Drug Safety (MFDS). Following mixed efficacy results in the overall patient population in the Phase 3 ALSUMMIT trial, CorestemChemon refined its regulatory strategy to focus on a clinically defined " slow progressor" subgroup. Post-hoc analyses in this subgroup showed clinically meaningful and internally consistent signals, including maintenance of ALS Functional Rating Scale-Revised (ALSFRS-R) scores, stabilization of slow vital capacity (SVC), and favorable trends in neurofilament light chain (NfL) biomarkers. The company believes these findings have supported a more structured and focused regulatory dialogue with the MFDS. The company expects this precision-targeted approach to further clarify the domestic regulatory pathway, while preserving the option for initial commercialization upon potential approval. A favorable MFDS decision would enable domestic market entry and generation of real-world evidence (RWE), which could support future global regulatory strategies. The company expects a final regulatory decision in Korea before the first quarter of 2026. CorestemChemon has been selected to join the Piedmont Triad Regenerative Medicine Innovation Engine, a U.S. regional innovation cluster supported by the National Science Foundation (NSF). The company stated that it is the first Korean biotechnology firm to be included in an NSF-backed regenerative medicine ecosystem. The selection was initiated by the Wake Forest Institute for Regenerative Medicine (WFIRM), which cited the scientific robustness of Neuronata-R's Phase 3 clinical dataset and the consistency observed in long-term real-world follow-up data. Participants in the NSF Engine is expected to provide access to translational research capabilities, manufacturing resources, and a broader regulatory network. To align more closely with this ecosystem, CorestemChemon plans to relocate its U.S. subsidiary to North Carolina. The company intends to leverage the cluster as a platform for regulatory engagement with the U.S. Food and Drug Administration (FDA), targeting submission of a Biologics License Application (BLA) in the third quarter of 2026. Commercialization Funding and Financial Position: To support commercialization readiness following potential domestic approval, CorestemChemon recently completed a rights offering, raising KRW 26.1 billion in operating capital (approximately USD 17.8 million, based on recent exchange rates). The proceeds are allocated to upgrading production facilities, establishing commercial-scale manufacturing systems, and preparing for both domestic and global regulatory processes. The company expects the capital raise to strengthen its financial position and reduce execution risk associated with manufacturing scale-up and regulatory preparation, while addressing near-term funding concerns. In a move widely interpreted as reinforcing market confidence, CEO Yang Gil-ahn recently executed a large-scale open-market share purchase. Over a two-week period, he acquired more than one million shares, representing an investment of approximately KRW 1.7 billion (approximately USD 1.2 million, based on recent exchange rate). The purchase coincided with the submission of supplementary regulatory materials to the MFDS and is viewed as a signal of management's conviction at a key regulatory inflection point. Following the transaction, the combined ownership stake of the controlling shareholder group increased to 10.32%, further strengthening alignment between management and shareholders.

New major risk - Shareholder dilution The company's shareholders have been substantially diluted in the past year. Increase in shares outstanding: 82% This is considered a major risk. Shareholder dilution occurs when there is an increase in the number of shares on issue that is not proportionally distributed between all shareholders. Often due to the company raising equity capital or some options being converted into stock. All else being equal, if there are more shares outstanding then each existing share will be entitled to a lower proportion of the company's total earnings, thus reducing earnings per share (EPS). While dilution might not always result in lower EPS (like if the company is using the capital to fund an EPS accretive acquisition) in a lot cases it does, along with lower dividends per share and less voting power at shareholder meetings. Currently, the following risks have been identified for the company: Major Risks Earnings have declined by 13% per year over the past 5 years. Shareholders have been substantially diluted in the past year (82% increase in shares outstanding). Minor Risks Share price has been volatile over the past 3 months (10% average weekly change).

Neuronata- Phase 3 Results Confirm Subgroup Benefit at PACTALS 2025, Strengthening Biomarker-Driven Pathway CorestemChemon Inc. announced that it has presented key findings from the Phase 3 ALSummit trial of Neuronata-R® (lenzumestrocel), an autologous bone marrow-derived mesenchymal stem cell (MSC) therapy for amyotrophic lateral sclerosis (ALS), at the PACTALS 2025 congress in Melbourne, Australia. The first session, chaired by Professor Seung-Hyun Kim of Hanyang University Hospital — a global leader in stem cell-based ALS research — brought together a panel of seven distinguished ALS experts from six countries. As part of the panel, Dr. Ryung-A Lee (Head of R&D Innovation, CorestemChemon) introduced the company and shared a brief overview of the Phase 3 trial results. In the second session, the full Phase 3 clinical trial (ALSUMMIT trial) results were formally presented by Professor Ki-Uk Oh (Department of Neurology, Advanced Regenerative Medicine Center, Hanyang University Hospital, and principal investigator of the ALSUMMIT trial). Subgroup Analysis Demonstrates Statistically Significant Benefit: While the overall trial did not meet its primary and secondary endpoints, Neuronata-R® showed meaningful efficacy in patients with slower disease progression. At 12 months, participants in this subgroup receiving Neuronata-R achieved: ALSFRS-R (functional rating scale): 31.2 vs. 26.4 in placebo (p=0.001), CAFS (Combined Assessment of Function and Survival): 20.95 and 24.78 vs. 17.92 in placebo (p=0.024; p=0.041), SVC (slow vital capacity, respiratory function): 62.2% vs. 50.6% in placebo (p=0.017, Study Group 2). These findings confirm Neuronata-R's potential to preserve function and respiratory capacity in ALS — outcomes directly linked to quality of life and survival. Biomarker Data Underscore Neuroprotective Effect: Biomarker analysis revealed sustained reductions in neurofilament light chain (NfL) and MCP-1, indicating a strong link between neuroprotection and clinical outcomes. This strengthens the case for biomarker-guided patient stratification and a precision-medicine strategy in ALS drug development, reflecting the evolving global regulatory landscape. Regulatory Pathway Toward Accelerated Approval: CorestemChemon stated that the PACTALS 2025 results mark an important step for regulatory discussions. The company plans to request a Type-C meeting with the U.S. Food and Drug Administration (FDA) in Fourth Quarter 2025 to discuss the dataset and biomarker-driven subgroup efficacy. Based on this discussion, CorestemChemon plans to submit a Biologics License Application (BLA) within 2026, aiming to pursue an accelerated approval pathway aligned with precedents in ALS, including FDA's decision on Tofersen.

Corestemchemon Announces Neuronata-R®? Stem Cell Therapy Shows Promise in Als Phase 3 Subgroup Analysis, Moves Toward Fda Accelerated Approval CorestemChemon announced Neuronata-R®?, an autologous bone marrow-derived mesenchymal stem cell (MSC) therapy for amyotrophic lateral sclerosis (ALS), has demonstrated meaningful efficacy signals in a subgroup of participants with slow disease progression in its recently completed Phase 3 trial. The therapy also showed consistent reductions in neurofilament light chain (NfL) levels -- a biomarker that served as the basis for FDA accelerated approval in ALS, including the recent decision on Tofersen -- supporting its potential to pursue a similar regulatory pathway. Developed by South Korean biotech company CorestemChemon, Neuronata-R®? utilizes MSCs derived from a participant's own bone marrow to modulate inflammation, protect motor neurons, and alter the neurodegenerative microenvironment through paracrine signaling. ALS, a rare and fatal disease with no cure, remains one of the most urgent areas of unmet medical need. Neuronata-R®®? aims to address the disease's complexology by leveraging the therapeutic potential of autologous MSCs. The final Clinical Study Report (CSR) confirmed that Neuronata-R®.

New minor risk - Market cap size The company's market capitalization is less than US$100m. Market cap: ₩123.5b (US$85.3m) This is considered a minor risk. Companies with a small market capitalization are most likely businesses that have not yet released a product to market or are simply a very small company without a wide reach. Either way, risk is elevated with these companies because there is a chance the product may not come to fruition or the company's addressable market or demand may not be as large as expected. In addition, if the company's size is the main factor, it is less likely to have many investors and analysts following it and scrutinizing its performance and outlook.
