These documents also provide capital-structure and governance information relevant to AstraZeneca’s UK issuer framework and SEC foreign-issuer reporting obligations.
AstraZeneca announced positive Phase III TROPION-Breast02 results for Datroway (datopotamab deruxtecan). The trial enrolled 644 patients and showed a statistically significant and clinically meaningful improvement in both overall survival (OS) and progression-free survival (PFS) versus investigator's choice chemotherapy as 1st-line treatment for patients with locally recurrent inoperable or metastatic triple-negative breast cancer (TNBC) for whom immunotherapy was not an option. Approximately 70% of metastatic TNBC patients are not candidates for immunotherapy, so chemotherapy remains the 1st-line standard of care for this group. TNBC represents about 15% of breast cancers globally (~345,000 diagnoses annually) and has a poor prognosis (median OS roughly 12 to 18 months, ~14% five-year survival). The safety profile was consistent with prior Datroway studies and data will be presented at an upcoming medical meeting and discussed with regulators.
AstraZeneca reported the total number of voting rights in the company as of 30 September 2025. The company states its issued share capital comprises 1,550,701,945 ordinary shares of US$0.25 and that no shares are held in treasury, giving a total of 1,550,701,945 voting rights. The notice explains this figure can be used by shareholders as the denominator to determine whether they must notify changes in their holdings under the UK Financial Conduct Authority's Disclosure and Transparency Rules.
The disclosure is a routine Transparency Directive update and does not include financial results, transactions, or forward guidance. Contact details for Investor Relations and Media are provided and the report is signed by the Company Secretary, Matthew Bowden, dated 01 October 2025.
AstraZeneca reported positive interim results from the DESTINY-Breast05 Phase III trial showing Enhertu (trastuzumab deruxtecan) produced a highly statistically significant and clinically meaningful improvement in invasive disease-free survival (IDFS) versus T-DM1 in patients with high-risk HER2-positive early breast cancer who had residual invasive disease after neoadjuvant therapy. Overall survival was not mature at the interim analysis and will be assessed later. The safety profile was consistent with known data and no new safety concerns were identified. Results will be presented at ESMO 2025 and shared with regulators; the trial enrolled 1,635 patients globally.
AstraZeneca is proposing a Harmonised Listing Structure to permit trading of its ordinary shares across the London Stock Exchange, Nasdaq Stockholm and the New York Stock Exchange by replacing its existing US ADR listing with a direct NYSE listing of ordinary shares. The company will remain headquartered, listed and tax resident in the UK and continue to follow UK governance standards. A Circular with a notice of a general meeting and detailed materials (including updated articles of association and a proxy form) has been published on the company website and filed with the National Storage Mechanism. The announcement includes a cautionary statement that forward-looking expectations involve risks and uncertainties.
AstraZeneca is asking shareholders to approve a Harmonised Listing Structure that would directly list AstraZeneca Shares on the NYSE while keeping listings on the London Stock Exchange and Nasdaq Stockholm. The proposal requires terminating the existing ADR programme, migrating settlement from CREST to DTC, and adopting amended articles to enable issuance of AstraZeneca DIs and, for certain restricted holdings, depositary receipts. The Board unanimously recommends the Resolution. The company highlights growth from $24.7bn revenue in 2015 to $54.1bn in 2024, core operating profit from $6.9bn to $16.9bn and core R&D spend from $5.6bn to $12.2bn; the US accounted for 43% of 2024 revenue and is forecast to be ~50% by 2030. Key dates: General Meeting 3 November 2025 and expected implementation by 2 February 2026.
AstraZeneca PLC reported a director/PDMR shareholding notification: Non-Executive Director Karen Knudsen acquired 9 American Depositary Shares (ADSs) on 9 September 2025 through reinvestment of the first interim dividend for the year ending 31 December 2025, which the company paid on 8 September 2025. Two ADSs equal one ordinary share of $0.25 each. The reported transaction price per ADS was $81.0499. The disclosure was made on 25 September 2025 and follows the EU Market Abuse Regulation reporting requirements.
AstraZeneca and Amgen's Tezspire (tezepelumab) received a positive CHMP recommendation for approval in the EU to treat adults with chronic rhinosinusitis with nasal polyps (CRSwNP). The opinion was based on the Phase III WAYPOINT trial, which showed Tezspire reduced nasal polyp size by a mean of 2.08 points and nasal congestion by 1.04 points versus placebo at Week 52, with p<0.001 for both co-primary endpoints.
WAYPOINT data also reported a 98% near-elimination of the need for surgery and an 89% reduction in systemic corticosteroid use versus placebo. Safety and tolerability were consistent with the known profile. Regulatory reviews are ongoing in multiple other countries.
AstraZeneca reported positive interim Phase III results from the TULIP-SC trial showing subcutaneous Saphnelo (anifrolumab) met the pre-specified primary endpoint of reduced disease activity versus placebo in patients with moderately to severely active, autoantibody-positive systemic lupus erythematosus (SLE). The reduction in disease activity was measured by the BICLA at week 52, which requires improvement across organs without new flares. The interim analysis included the first 220 participants reaching week 52 from a randomised 1:1 trial of 367 participants receiving 120mg subcutaneous anifrolumab once weekly versus placebo on top of standard therapy. Safety was consistent with the known IV profile. Results are under regulatory review and slated for presentation at ACR Convergence 2025.
AstraZeneca reported top-line results from the RESOLUTE Phase III trial of Fasenra (benralizumab) in COPD. The trial randomized 689 participants with moderate to very severe COPD, all on background ICS/LABA/LAMA therapy and with elevated blood eosinophils (≥300 cells/µL). The primary endpoint—annualised rate of moderate or severe exacerbations in patients with ≥3 prior-year exacerbations—showed a numerical improvement with Fasenra but did not reach statistical significance. Safety and tolerability were consistent with Fasenra's known profile. AstraZeneca said it will analyse the full data set and share results with the scientific community. Fasenra is already approved for severe eosinophilic asthma and other eosinophilic conditions in multiple countries.
AstraZeneca reported its total voting rights and issued share capital. The company states that as at 31 August 2025 there are 1,550,692,963 ordinary shares of US$0.25 each carrying voting rights, with no shares held in treasury. This figure is presented so shareholders can use it as the denominator to determine whether they must notify changes in their holdings under the UK Disclosure and Transparency Rules.
The notice is a routine transparency disclosure and does not include financial results, transactions, or changes to capital structure beyond the voting‑rights count.
