About LYSOGENE

https://www.lysogene.com

Lysogene was a clinical-stage biotechnology company that specialized in the research and development of gene therapies for rare, inherited neurodegenerative diseases affecting the central nervous system (CNS). The company's approach focused on delivering a functional copy of a deficient gene directly to the brain to address the root cause of the targeted disorder. Its pipeline included investigational treatments for lysosomal storage diseases such as Sanfilippo syndrome type A (MPS IIIA) and GM1 gangliosidosis. Following clinical and financial challenges, the company initiated judicial liquidation proceedings in 2023.

Franchissement de seuils
Major Shareholding Notification Classification · 1% confidence The document is titled "Déclaration de franchissement de seuils (article L. 233-7 du code de commerce)" which translates to 'Declaration of crossing thresholds (Article L. 233-7 of the Commercial Code)'. It explicitly states that Sarepta Therapeutics, Inc. crossed the 5% threshold of capital and voting rights in LYSOGENE on October 25, 2018. This content directly corresponds to the definition of a Major Shareholding Notification, which involves reporting changes in significant share ownership levels crossing specific thresholds. The corresponding code is MRQ.

Communicated under the obligation to provide permanent information / Other communications
Regulatory Filings Classification · 1% confidence The document is a short press release dated June 15, 2018, announcing that Lysogene will be included in several Euronext indexes (CAC Small, CAC Mid & Small, CAC All-Tradable). This is a specific corporate event announcement related to stock market listing status and index inclusion, which is not explicitly covered by the primary financial report codes (10-K, IR, ER). It is not a Director's Dealing (DIRS), Dividend Notice (DIV), or Capital Change (SHA/CAP). Since it is a general, non-financial-result-focused announcement that doesn't fit the other specific categories, it falls best under the general regulatory/corporate announcement category, RNS (Regulatory Filings), as it is a public disclosure of a material event.

Communiqués au titre de l'obligation d'information permanente / Autres communiqués
Regulatory Filings Classification · 1% confidence The document is a press release dated June 15, 2018, announcing that the company Lysogene is being integrated into several CAC indices (CAC Small, CAC Mid & Small, CAC All-Tradable) by Euronext, effective after market close on that date. This is a corporate announcement regarding market status and investor visibility, not a core financial report (like 10-K or IR), a management change (MANG), or a dividend notice (DIV). It is a general regulatory/market announcement. Since it doesn't fit perfectly into the specific categories like DIRS, CAP, or LTR, and it is a formal announcement of a market event, it best fits the general 'Regulatory Filings' (RNS) category, which serves as a fallback for miscellaneous official announcements, or potentially a Capital/Financing Update (CAP) due to the impact on stock listing, but RNS is broader for such market news. Given the nature of index inclusion announcements, RNS is the most appropriate general regulatory filing category.

Communiqués de mise à disposition de documents / Modalités de mise à disposition document de référence ou de ses actualisations
Report Publication Announcement Classification · 1% confidence The document is a press release dated June 4, 2018, titled "Lysogene annonce la mise à disposition de son Document de Référence de l'exercice 2017" (Lysogene announces the availability of its 2017 Reference Document). The text explicitly states that the 'Document de Référence' (Reference Document) has been filed with the AMF (Autorité des marchés financiers) and is now available to the public on the company and regulator websites. This structure—a short announcement stating that a formal report is now available—fits the definition of a Report Publication Announcement (RPA). The document length (3875 chars) is also short, reinforcing the 'MENU VS MEAL' rule, meaning it is the announcement, not the full Reference Document itself (which would likely be classified as a 10-K equivalent or similar comprehensive filing if provided in full).

Document availability communications / Methods of making financial reports or updated prospectuses available
Report Publication Announcement Classification · 1% confidence The document is a short press release dated June 4, 2018, explicitly titled: "Lysogene announces the publication of its 2017 Registration Document." It states that the document has been recorded by the AMF and is now available on the company's and regulator's websites. According to Rule #2 (The 'MENU VS MEAL' Rule), a short document announcing the publication or availability of a formal report (like a Registration Document, which is often equivalent to a 10-K or comprehensive annual filing in structure, but here it's being announced separately) should be classified as a Report Publication Announcement (RPA), rather than the report itself. The text is focused entirely on the announcement of the availability of the '2017 Registration Document'.

Communicated under the obligation to provide permanent information / Other communications
Board/Management Information Classification · 1% confidence The document is a press release dated May 15, 2018, announcing the appointment of Dr. Ralph Laufer as the Chief Scientific Officer (CSO) and a member of the management team of Lysogene. This type of announcement, detailing changes in senior management or the board of directors, directly corresponds to the definition of 'Board/Management Information'. The document is not a full annual report (10-K), an earnings release (ER), or a transcript (CT). Therefore, the appropriate classification is MANG.
