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 German stocks, typically moving 13% a week. This is considered a major risk. Share price volatility increases the risk of potential losses in the short-term as the stock tends to have larger drops in price more frequently than other stocks. It may also indicate the stock is highly sensitive to market conditions or economic conditions rather than being sensitive to its own business performance, which may also be inconsistent. Currently, the following risks have been identified for the company: Major Risks Share price has been highly volatile over the past 3 months (13% average weekly change). Earnings have declined by 42% per year over the past 5 years. Minor Risks Currently unprofitable and not forecast to become profitable next year (UK£17m net loss next year).

4basebio PLC Launches Enzymatic ssDNA Platform 4basebio PLC announced the commercial launch of its high-capacity single-stranded DNA (ssDNA) product line to accelerate the development of safer, more precise genetic therapies by enabling targeted gene editing, advanced cell engineering, and innovative nucleic acid-based medicines. Built on a proprietary enzymatic manufacturing process, the platform provides biopharma with high-purity, long-form ends protected ssDNA templates, designed to overcome critical manufacturing and performance bottlenecks associated with traditional chemical synthesis in CRISPR-based gene editing, enabling large-scale, clinically viable therapeutics. With the growth of gene editing and with a particular need for complex "knock-in" applications, the demand for longer, purer and safer DNA templates has increased exponentially. 4basebio’s ssDNA offering enables the production of constructs up to 10,000 nucleotides with protected ends, ensuring stability, reduced immunogenicity and a cleaner path to clinical manufacturing. The technical advantages of the platform will be showcased at the upcoming American Society of Gene & Cell Therapy (ASGCT) Annual Meeting in Boston, MA. Amine Bouchareb, Director of Molecular Biology and Gene Editing at 4basebio, will deliver a presentation titled "An enzymatic ssDNA platform addresses manufacturing and performance bottlenecks in non-viral CRISPR gene editing" on 14 May at 9:00 AM EDT. At ASGCT, I look forward to presenting data that demonstrates how our long-form ssDNA constructs significantly enhance Homology Directed Repair (HDR) gene editing efficiency while maintaining superior cell viability in sensitive primary cell types. This technology is the bridge between discovery-phase editing and large-scale clinical success. This announcement contains inside information for the purposes of Article 7 of EU Regulation 596/2014 as amended by regulation 11 of the Market Abuse (Amendment) (EU Exit) Regulations 2019/310.

New minor risk - Shareholder dilution The company's shareholders have been diluted in the past year. Increase in shares outstanding: 3.9% This is considered a minor 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 Less than 1 year of cash runway based on free cash flow trend (-UK£6.5m free cash flow). Earnings are forecast to decline by an average of 11% per year for the foreseeable future. Revenue is less than US$1m (UK£354k revenue, or US$446k).

4basebio UK Societas Announces Application Filed for Protected Linearised Synthetic DNA 4basebio UK Societas announced it has filed a patent application for a novel protected and stabilized linear synthetic DNA type, “osDNA™”. DNA is susceptible to degradation by nucleases which are naturally occurring enzymes within organisms and which have a vital role in the regulation of many cellular processes, while also protecting against foreign DNA species. Enzymatic DNA degradation can render gene therapies ineffective and is a substantial consideration when developing gene therapies or DNA vaccines. The Company’s novel osDNA™ product has demonstrated increased longevity compared to conventional DNA types. Unlike hpDNA™ which is a closed DNA construct, osDNA™ is open linear DNA and incorporates all of the established benefits of hpDNA™ over widely used plasmid DNA, in particular the absence of bacterial backbone, antibiotic resistance genes or endotoxins. osDNA™ therefore also benefits from a high level of purity. Furthermore, a long terminal mono-nucleotide sequence (homopolymeric sequence) is an essential feature of high-quality mRNA. These types of sequences are known to be difficult to manufacture through plasmid fermentation. osDNA™ is readily able to incorporate these sequences, positioning osDNA™ as a highly suited template for the production of mRNA products, an area of significant commercial opportunity for the Company’s products and technologies.
