Generation Bio Receives Written Notification from Nasdaq Regarding Non-Compliance with the Minimum Bid Price Requirement Under Nasdaq Listing Rule 5450(a)(1) On February 24, 2025, Generation Bio Co. (the ‘Company’) received written notification (the ‘Notice’) from the Listing Qualifications Department (the ‘Staff’) of the Nasdaq Stock Market (‘Nasdaq’) that, because the closing bid price for the Company’s common stock has fallen below $1.00 per share for 30 consecutive business days, the Company no longer complies with the minimum bid price requirement for continued listing on the Nasdaq Global Select Market, pursuant to Nasdaq Listing Rule 5450(a)(1) (the ‘Bid Price Requirement’). The Notice has no immediate effect on the listing of the Company’s common stock on the Nasdaq Global Select Market, which will continue to be listed and trade on Nasdaq subject to the Company’s continued compliance with the other listing requirements. Pursuant to Nasdaq Listing Rule 5810(c)(3)(A), the Company has an initial period of 180 calendar days, or until August 25, 2025 (the ‘Compliance Date’), to regain compliance with the Bid Price Requirement. To regain compliance, the closing bid price of the Company’s common stock must be at least $1.00 per share for a minimum of 10 consecutive business days prior to the Compliance Date, at which time the Staff will provide written notification to the Company that it complies with the Bid Price Requirement, unless the Staff exercises its discretion to extend this 10-day period pursuant to Nasdaq Listing Rule 5810(c)(3)(H). If the Company does not regain compliance by the Compliance Date, it may be eligible for an additional 180 calendar day grace period. To qualify, the Company would be required to transfer the listing of its common stock to the Nasdaq Capital Market, provided that it meets the continued listing requirement for the market value of publicly held shares and all other initial listing standards of the Nasdaq Capital Market, with the exception of the Bid Price Requirement. To effect such a transfer, among other things, the Company would also need to pay an application fee to Nasdaq and provide written notice to the Staff of its intention to cure the deficiency during the additional compliance period by effecting a reverse stock split, if necessary. However, if it appears to the Staff that the Company will not be able to regain compliance with the Bid Price Requirement during the additional compliance period, or if the Company does not meet the other listing standards, the Staff could provide written notice that the Company’s common stock will be subject to delisting. Upon receipt of such notice, under Nasdaq rules, the Company may appeal the Staff’s delisting determination to a Nasdaq Listing Qualifications Panel (the ‘Panel’). The Company expects that its common stock would remain listed pending the Panel’s decision. However, there can be no assurance that, if the Company does appeal the delisting determination by the Staff to the Panel, that such appeal would be successful. The Company intends to monitor the closing bid price of its common stock and may, if appropriate, consider available options to regain compliance with the Bid Price Requirement. There can be no assurance that the Company will be able to regain compliance with the Bid Price Requirement or will otherwise remain in compliance with other Nasdaq listing criteria.

New minor risk - Market cap size The company's market capitalization is less than US$100m. Market cap: US$95.5m 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. Currently, the following risks have been identified for the company: Minor Risks Currently unprofitable and not forecast to become profitable over next 3 years (US$84m net loss in 3 years). Share price has been volatile over the past 3 months (12% average weekly change). Market cap is less than US$100m (US$95.5m market cap). Major Estimate Revision • Nov 13

Generation Bio Co. Announces the Presentation of Preclinical Data on iqDNA and ctLNP Platforms At the ASGCT 27th Annual Meeting Generation Bio Co. presented five posters on its immune-quiet DNA (iqDNA) and cell-targeted lipid nanoparticle (ctLNP) platforms as well as its enzymatic synthesis manufacturing at the American Society of Gene and Cell Therapy (ASGCT) 27th Annual Meeting. A sixth presentation on the company's ctLNP platform will be discussed in an oral presentation on May 11, 2024. Data included in the posters describe iqDNA as a modified, structured, partially single-stranded DNA that evades innate immunity while remaining transcriptionally active in the cell. In mouse studies, the immune profile of iqDNA is consistent with avoidance of key innate immune pathways such as cGAS-STING, which is known to have a significantly lower binding affinity for single-stranded DNA than double-stranded DNA. Given the non-immunogenic nature of iqDNA, Generation Bio believes it can now create novel therapies with a wide therapeutic index, which has been a major challenge to the development of in vivo DNA-based genetic medicines. The company invented iqDNA using its proprietary rapid enzymatic synthesis (RES) for DNA production. RES is a cell-free process that permits chemical and structural changes with a high degree of control, facilitating heightened DNA functionality through engineering molecular design and components. Because RES does not rely on cellular or viral components, it consistently produces 99% pure material in approximately one week, marking a significant improvement over biologic methods, which are often lengthy and complex. Further, due to the nature of enzymatic processes, iqDNA can be manufactured at scale to support clinical and global commercial demands without the challenges faced by cell-culture based production. Generation Bio continues to leverage RES to advance its iqDNA platform by optimizing various structural and chemical elements. In new data presented at ASGCT, a second generation of iqDNA achieved higher luciferase expression than first-generation iqDNA. The company is currently testing formulations of second-generation iqDNA encoding Factor VIII. The company’s ctLNP platform is designed to reach a broad set of target cell types and tissues with exquisite selectivity. Data presented at ASGCT describe the foundation of the platform, Generation Bio’s “stealth” LNP, which was engineered in part by making structural modifications to the parental ionizable lipid composition. Cell-specific targeting is achieved by optimizing ligand selection and linker chemistry. Additional data on T cell delivery, including the in vivo delivery of therapeutic transgenes via ctLNP, will be discussed in an oral presentation on May 11, 2024. Announcement • Apr 26

New major risk - Revenue and earnings growth Earnings are forecast to decline by an average of 1.8% per year for the foreseeable future. This is considered a major risk. Ultimately, shareholders want to see a good return on their investment and that generally comes from sharing in the company's profits. If profits are expected to decline, then in most cases the share price will decline over time as well. In addition, if the company pays dividends it will also likely need to reduce or cut them, striking a dual blow to total shareholder returns. Currently, the following risks have been identified for the company: Major Risk Earnings are forecast to decline by an average of 1.8% per year for the foreseeable future. Minor Risks Currently unprofitable and not forecast to become profitable over next 3 years (US$126m net loss in 3 years).

Generation Bio Co. Announces Breakthrough in Its Non-Viral Genetic Medicine Platform with Novel "Immune-Quiet" Dna Generation Bio Co. announced the development of a proprietary, novel DNA called immune-quiet DNA (iqDNA). iqDNA is an optimized variant of the company's closed-ended DNA (ceDNA) that upon systemic administration with Generation Bio's lipid nanoparticle (LNP) delivery has shown cytokine levels and tolerability comparable to chemically modified messenger RNA (mRNA) in mice and non-human primates (NHPs). Generation Bio's non-viral genetic medicine platform aims to advance durable, redosable, and titratable therapies to reach potentially hundreds of millions of patients worldwide. The company has made deep investments in its three proprietary platform technologies, comprising novel DNA cargos, rapid enzymatic synthesis (RES) manufacturing, and cell-targeted LNP (ctLNP) delivery. Concurrent with extending its cash runway, the company is increasing investment in its iqDNA and ctLNP platforms. Systemic dosing in mouse and NHP studies demonstrates that iqDNA delivered via LNP evades detection by the key innate immune pathways that are reactive to DNA. Due to the superior tolerability profile of iqDNA, Generation Bio is discontinuing development of prior ceDNA constructs and is advancing iqDNA as the cargo for its lead program in hemophilia A as well as for all other programs. Scaling of iqDNA factor VIII for NHP testing is underway, leveraging existing RES systems and processes. Major Estimate Revision • Aug 17

Generation Bio Co. Announces Update to its Good Manufacturing Process Manufacturing Strategy Generation Bio Co. announced that it is updating its Good Manufacturing Process manufacturing strategy to integrate efficiencies enabled by improvements to its proprietary rapid enzymatic synthesis process for the production of closed-ended DNA (ceDNA). RES is a cell-free process that delivers three key benefits compared to biologics-based DNA manufacturing approaches: consistent yields of highly pure ceDNA, potential to scale to hundreds of millions of doses, and short production cycles. In July 2021, Generation Bio announced plans to deploy RES for ceDNA across all of its portfolio programs and had entered into a lease agreement to build out a GMP facility in order to scale RES for clinical and initial commercial supply. Through further process development of RES, the company has achieved a significant increase in scale while maintaining high productivity and ceDNA purity, and now projects underutilization of the planned GMP facility. The company will seek to sublease this facility and intends to execute an alternative GMP approach that retains control over personnel, quality, infrastructure and process know-how.

Generation Bio Provides Update on Preclinical Studies for Hemophilia A Program Generation Bio Co. provided an update on factor VIII expression from a series of mouse and companion non-human primate (NHP) studies in hemophilia A, as well as an update on the development of its non-viral genetic medicine platform. Generation Bio’s proprietary genetic medicine technology comprises a closed-ended DNA (ceDNA) delivered via a novel, cell-targeted lipid nanoparticle (ctLNP). In July 2021 the company announced that it would incorporate its novel, proprietary rapid enzymatic synthesis (RES) for ceDNA production into its pipeline programs. RES has improved ceDNA purity to 99%. In mouse studies, RES-derived ceDNA delivered by ctLNP generated peak mean human factor VIII expression of 205% of normal at 2.0 mg/kg. This is compared to peak mean human factor VIII expression of 23% of normal at 2.0 mg/kg using ceDNA produced by the company’s prior Sf9-based manufacturing process. In addition to the increased potency attributed to the RES-produced ceDNA and to ctLNP production process innovations, the company observed lower variability of factor VIII expression and of tolerability within and between mouse studies. Findings from companion studies in NHPs demonstrated human factor VIII expression of up to 2% of normal at 2.0 mg/kg, with higher-than-expected variability in both factor VIII expression and tolerability within and across studies. Additional optimization is needed to translate the improvement in potency and reduction in variability observed in mice to NHP, and to support nomination of a development candidate for the company’s hemophilia A program.

Generation Bio Announces Plan to Scale Next-Generation Rapid Enzymatic Manufacturing Process Across Portfolio and Provides Pipeline Update Generation Bio Co. announced that it plans to deploy next-generation rapid enzymatic synthesis (RES) for manufacturing of its closed-ended DNA (ceDNA) constructs across all portfolio programs. RES is a cell-free process that has the following advantages over cell-based manufacturing: Quality: Consistently yields highly pure ceDNA and reduces the variability inherent in cell-based manufacturing, which may have important regulatory and clinical benefits for Generation Bio’s entire pipeline, including its lead hemophilia A program; Scale: Potential to expand ceDNA manufacturing scale to hundreds of millions of doses, supporting the company’s intention to develop programs for prevalent diseases; Speed: Shortens the ceDNA production cycle from 28 days to one day, which will accelerate preclinical research and development across the company’s portfolio. The company has signed a lease agreement to build out a state-of-the-art cGMP (current good manufacturing practice) facility of approximately 104,000 square feet in Waltham, Mass. to scale RES for clinical and initial commercial supply. The facility is expected to be operational in 2023, enabling an Investigational New Drug (IND) application and clinical development for the company’s lead hemophilia A program. The company is using existing infrastructure for RES production of research material. Generation Bio anticipates incurring net lease costs of $104 million over a 12-year period and investing up to $45 million in the new manufacturing facility over the next two years. The company plans to continue partnering with contract manufacturing organizations during and after construction to ensure redundancy and secure additional ceDNA supply. Expenditures on the new facility are not expected to impact Generation Bio’s cash runway, which is sufficient to fund key milestones into 2024. As Generation Bio transitions to RES, it expects to update its program development strategy and timelines across its pipeline. Generation Bio is currently advancing its liver-directed, cell-targeted lipid nanoparticle delivery system with RES for the lead hemophilia A program. The company expects to report factor VIII expression data using RES-produced drug product in non-human primates by year-end. Recent Insider Transactions Derivative • Jul 11

Generation Bio Announces Two Non-Viral Gene Therapy Achievements: Target Levels of Factor VIII Expression in Hemophilia A Mice and Translation of Expression from Mice to Non-Human Primates Generation Bio Co. announced data from a study achieving tolerability and targeted factor VIII expression levels in hemophilia A mice with a single dose of closed-ended DNA (ceDNA) delivered via the company’s novel, cell-targeted lipid nanoparticle (ctLNP) system. In this study, conducted with a ceDNA development construct, a dose response was observed across three cohorts, with the highest dose of 2.0 mg/kg yielding a mean human factor VIII expression of 23% of normal. The company also announced data from studies conducted with a ceDNA research construct delivered via ctLNP demonstrating approximately 2:1 species translation from mice to non-human primates (NHPs). All doses in mice and NHPs were well-tolerated up to the highest dose of 2.0 mg/kg. These data confirm delivery of ceDNA to the liver via ctLNPs in higher species. Generation Bio has previously demonstrated in immunocompetent mice that its ceDNA constructs with human factor IX achieved durable expression for months and that expression increased proportionately with redosing. In parallel with hemophilia A, Generation Bio plans to advance programs in phenylketonuria (PKU) as well as in additional rare and prevalent diseases that are addressable using the company’s liver-specific ctLNP delivery system and established, capsid-free manufacturing. Translation from mouse to NHP was established by delivering the same weight-adjusted dose of ceDNA-ctLNP in each species. Two separate studies were conducted. In the first study, a mean human factor VIII expression level of ~1% of normal was observed in mice at day 7 following a single dose of a ceDNA research construct delivered systemically via a liver-directed ctLNP at 1 mg/kg. This translated to a mean human factor VIII expression level of ~1% of normal in NHPs at day 5 using identical material and weight-adjusted dosing (1 mg/kg). In a second study employing a similar ctLNP, a mean human factor VIII expression level of ~3% of normal was observed in mice at day 5 following a single dose of a ceDNA research construct at 2 mg/kg. This translated to a mean factor VIII expression level of 1% of normal in NHPs at day 5 using identical material and weight-adjusted dosing at 2 mg/kg. In totality, the 2:1 expression ratio from mice to NHPs is similar to that observed across other modalities delivered via LNPs, including RNAi and mRNA, and establishes a basis for final development candidate selection. The expression levels in mice using a ceDNA development construct, coupled with the 2:1 expression ratio from mice to NHPs and expected 1:1 translation from NHPs to humans, support selection of a final hemophilia A clinical development candidate this year. The observed expression levels in mice with a ceDNA development construct may correspond to or exceed the 5% of normal threshold in humans that has been clinically proven to prevent serious bleeds in patients. Doses of ceDNA-ctLNP in both mice and NHPs were well tolerated up to 2 mg/kg, the highest dose evaluated. There were no adverse clinical observations, changes in clinical pathology, or histopathology findings including in the liver and spleen in NHPs. Generation Bio’s ctLNP employs N-acetyl galactosamine, or GalNAc, as the ligand for targeting of liver cells via the asialoglycoprotein receptor, or ASGPr. GalNAc-ASGPr is a well-validated, selective ligand-receptor pair for systemic delivery to hepatocytes. In previously released data from a study in immunocompetent mice, a single intravenous dose of ceDNA formulated in an LNP yielded long-term expression in the liver for months using the reporter protein luciferase and human factor IX. LNP delivery does not stimulate an antibody response, thereby enabling redosing and overcoming a major limitation of viral gene therapy. Generation Bio has previously released data showing that ceDNA delivered in an LNP does not induce neutralizing antibodies and can be redosed in mice with normal immune systems. Redosing five weeks after the initial dose proportionately increased expression using both the reporter protein luciferase and human factor IX in mice. After the first administration of a factor IX ceDNA research construct in an LNP, mice demonstrated 5% to 10% activity levels of factor IX protein in the blood. After repeat administration at the same dose, the activity levels rose to 10% to 20%. These results support the potential of Generation Bio’s non-viral gene therapy platform to safely titrate patients to the desired level of protein expression and to enable repeat dosing if needed to maintain expression over a lifetime.
