New major risk - Market cap size The company's market capitalization is less than US$10m. Market cap: US$6.55m This is considered a major 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. Currently, the following risks have been identified for the company: Major Risks Shares are highly illiquid. Revenue is less than US$1m. Market cap is less than US$10m (US$6.55m market cap).

Synlogic, Inc. Receives Notice of Nasdaq Delisting Due to Public Shell Status and Operational Decline On November 21, 2025, Synlogic, Inc. received a letter from the Listing Qualifications Department of The Nasdaq Stock Market LLC that stated the Staff’s belief that the Company is a “public shell” and that, therefore, the continued listing of its securities is no longer warranted in the view of the Staff. In the Notice, the Staff explained that it based this belief on its review of the Company’s public disclosures and materials submitted to the Staff by the company. In addition, the Staff noted its belief is supported by the Company’s lack of revenue generating assets and the substantial reduction in employees and operations since February 2024. The Staff also considered the company’s quarterly reports on Forms 10-Q filed on May 8, 2025, August 7, 2025, and November 13, 2025, respectively, which indicated that the Company has not generated any revenue for the nine months ended 2025 and that the company had research and development expenses of only $16,000. The Notice further advised that, unless the Company timely requests a hearing before a Hearings Panel, it would be subject to suspension/delisting. The company disagrees with the Staff’s view regarding the Company’s status as a “public shell” and, accordingly, intends to timely request a hearing. The hearing request will automatically stay any suspension or delisting action pending the hearing and the expiration of any additional extension period that may be granted by the Panel following the hearing. However, there can be no assurance that the Company’s hearing will be successful, or that, if successful, the Company will be able to maintain compliance with all applicable listing criteria.

New major risk - Share price stability The company's share price has been highly volatile over the past 3 months. It is more volatile than 90% of British stocks, typically moving 9.3% a week.

Currently, the following risks have been identified for the company: Major Risks Less than 1 year of cash runway based on free cash flow trend (-US$49m free cash flow). Share price has been highly volatile over the past 3 months (9.3% average weekly change). Shareholders have been substantially diluted in the past year (156% increase in shares outstanding).

Synlogic, Inc. Announces Publication of Preclinical and Clinical Data for SYNB1353 as a Potential Treatment for Classical Homocystinuria Synlogic, Inc. announced the publication of a manuscript detailing the development and activity of SYNB1353 in preclinical models and demonstrating safety, tolerability, and clinical proof of mechanism in healthy volunteers through the successful lowering of methionine (Met), a precursor to homocysteine, in a dietary model of classical homocystinuria (HCU). Among findings outlined in the manuscript, SYNB1353 efficiently degraded both dietary and entero-recirculating methionine to prevent its absorption and subsequent conversion to homocysteine in preclinical models, suggesting that SYNB1353 should result in lowering of plasma homocysteine levels in HCU patients. In addition, in results from the clinical study in healthy volunteers, SYNB1353 was generally well-tolerated and adverse events were mild to moderate, transient, and predominantly gastrointestinal in nature. The proportion of subjects reporting gastrointestinal events were similar for the SYNB1353 and placebo cohorts (36.4% and 37.5%, respectively). Announcement • Nov 18

Synlogic, Inc. Announces Initiation of Synpheny-3 Global, Pivotal Phase 3 Study Evaluating SYNB1934 for Treatment of Phenylketonuria Synlogic, Inc. announced the initiation of Synpheny-3, a global, pivotal Phase 3 study evaluating the efficacy and safety of SYNB1934 as a potential treatment for phenylketonuria (PKU). Synpheny-3 is a randomized, placebo-controlled, global, multi-center, pivotal Phase 3 clinical trial designed to evaluate the efficacy and safety of SYNB1934 as a treatment for PKU. The final trial design incorporates feedback from global regulatory agencies including the U.S. Food and Drug Administration (FDA). The global study will enroll approximately 150 patients with plasma phenylalanine (Phe) levels at baseline of >360 µM. Synpheny-3 will include patients ages 18 years and older; an initial subset of data from patients in Part 1 will be used to assess the opportunity to lower the age of enrollment to 12 years of age. Study participants may follow their usual diet while participating in the trial. Synpheny-3 is expected to be conducted at approximately 30 clinical sites across the United States, Canada, Germany, Denmark, Israel, Turkey and Georgia. The study has been designed for patient convenience, and offers opportunities to participate in person, or in a virtual or hybrid format. The study consists of three parts: Part 1 is a run-in period, enabling individualized titration across three potential dose levels (3x1011, 6x1011 and 1x1012), with patients spending a minimum of three weeks at each dose. Part 2 of the trial is a four-week, placebo-controlled, randomized withdrawal that will be used to assess the primary endpoint: change in levels of plasma Phe, with a primary analysis conducted among responders from Part 1. The definition for responders is a reduction in plasma Phe from baseline of >20%. Part 3 is an open-label extension that may extend for up to three years. Announcement • Jan 20
