Welcome to our dedicated page for GSK PLC SEC filings (Ticker: GSK), a comprehensive resource for investors and traders seeking official regulatory documents including 10-K annual reports, 10-Q quarterly earnings, 8-K material events, and insider trading forms.
The SEC filings page for GSK plc (GSK) provides access to the company’s regulatory disclosures as a foreign private issuer. GSK files an annual report on Form 20-F and frequent current reports on Form 6-K under the Securities Exchange Act of 1934. These documents, together with information on American Depositary Shares listed on the New York Stock Exchange, form a key source of official information for investors analyzing GSK stock.
Recent Form 6-K filings include multiple transaction notifications for persons discharging managerial responsibilities (PDMRs) and persons closely associated with them. These reports detail acquisitions of ordinary shares or American Depositary Shares, often through dividend reinvestment plans, share reward plans or the exercise of options under GSK’s share save arrangements, and specify trade dates, prices, volumes and trading venues such as the London Stock Exchange and New York Stock Exchange.
Other 6-K filings report total voting rights, including the number of issued ordinary shares, treasury shares and the resulting total voting rights figure. This information helps shareholders determine whether they must notify changes in their holdings under applicable disclosure rules. Additional 6-K submissions incorporate press releases on significant product approvals, clinical trial results and agreements, such as approvals for Exdensur (depemokimab), Nucala (mepolizumab) in COPD, Shingrix prefilled syringe presentations, and positive phase III results for bepirovirsen in chronic hepatitis B.
On Stock Titan, these filings are complemented by AI-powered summaries that explain the practical meaning of each document. Investors can quickly understand insider dealing reports, changes in capital structure, and major regulatory or clinical events without reading every line of the original filing. Real-time updates from EDGAR ensure that new GSK 6-K submissions, as well as the annual 20-F, appear promptly, while insider transactions analogous to Form 4 in the US domestic context are captured through the PDMR transaction notifications.
By using this page, users can review GSK’s historical and current SEC filings, track patterns in executive and director share dealings, and connect clinical and regulatory announcements to their formal disclosure record, all with the support of AI-generated explanations.
GSK plc reports that the European Medicines Agency has accepted for review a marketing authorisation application for bepirovirsen, an investigational antisense oligonucleotide for adults with chronic hepatitis B. The submission is backed by Phase III B‑Well 1 and B‑Well 2 trials, which met their primary endpoint and showed statistically significant, clinically meaningful functional cure rates versus standard of care.
Chronic hepatitis B affects an estimated 3.2 million people in Europe and more than 250 million worldwide, with current nucleos(t)ide analogue therapies often requiring lifelong treatment and achieving functional cure in only about 1% of patients. Bepirovirsen is designed to target hepatitis B viral RNA, reduce hepatitis B surface antigen, and stimulate the immune system, with trials indicating an acceptable safety and tolerability profile. The data will be presented at a scientific congress and submitted for peer‑reviewed publication in 2026, while bepirovirsen remains unapproved globally.
