Regulatory Basis: WpHG Article 40 Voting Rights Notification for Bayer

The notification complies with Article 40, Section 1 of the WpHG, Germany’s principal securities trading law, which mandates that any entity crossing defined voting rights thresholds in a German-listed company must promptly notify both the issuer and BaFin, the German financial regulator. This rule enhances transparency regarding ownership structures of publicly traded German firms, allowing investors and the market to track significant shifts in control. Bayer Aktiengesellschaft, as a regulated German market-listed entity, remains subject to these ongoing disclosure obligations.

Distributed by EQS News, a service of EQS Group, the announcement targets Europe-wide dissemination in line with Transparency Directive requirements implemented in German law. Bayer Aktiengesellschaft is solely responsible for the notification content. The announcement date was 14 July 2026 at 14:33 CET/CEST, with the threshold crossing event occurring on 8 July 2026 and the formal notification filed on 13 July 2026, as noted in section 10 of the disclosure.

Amundi S.A.’s Voting Rights in Bayer Rise from 2.99% to 3.09% as of 8 July 2026

The filing confirms that Amundi S.A., based in Paris, increased its aggregated voting rights in Bayer Aktiengesellschaft from 2.99% to 3.09% as of 8 July 2026. This 0.10 percentage point increase crossed the critical 3% threshold under German securities law, triggering mandatory disclosure. Bayer’s total voting rights pool, as per Section 41 WpHG, totals 982,424,082 voting rights, which serves as the basis for percentage calculations.

In absolute terms, Amundi’s stake represents 30,375,174 shares held indirectly under Section 34 WpHG through controlled subsidiaries, with no shares directly held under Section 33 WpHG. Additionally, Amundi holds an instrument position of 13,770 voting rights under Section 38(1) no. 1 WpHG related to securities lent, which accounts for 0.00% of total voting rights. No holdings are reported under Section 38(1) no. 2 WpHG.

Bayer Aktiengesellschaft: A Leading Global Life Sciences Company in Pharmaceuticals and Crop Science

Bayer Aktiengesellschaft is a premier global life sciences company operating in pharmaceuticals, consumer health, and agricultural sciences, including crop protection and seed technologies. Headquartered at Kaiser-Wilhelm-Allee 1, Leverkusen, Germany, Bayer operates worldwide. Its pharmaceutical division markets prescription medicines, while its Crop Science division, including Monsanto acquired in 2018, produces herbicides, fungicides, insecticides, and genetically enhanced seeds. The consumer health segment offers over-the-counter products sold globally.

Bayer is listed on the Frankfurt Stock Exchange under ISIN DE000BAY0017, referenced in Amundi’s voting rights notification. The company’s revenue streams are diversified across its three main divisions. Bayer has faced notable legal and financial challenges related to litigation over its Roundup glyphosate-based herbicides, impacting financial results and investor sentiment. Consequently, shifts in institutional shareholding, such as Amundi’s threshold crossing, attract market attention.

Amundi’s Indirect Shareholding via Multiple Subsidiaries Across Europe and Asia Under Sec. 34 WpHG

The notification highlights the complexity of Amundi’s ownership structure. Amundi S.A. states it is not controlled by another entity and holds no shares directly; instead, the entire 30,375,174-share position is attributed through a chain of controlled subsidiaries operating in various jurisdictions. These subsidiaries include Amundi Asset Management S.A.S., CPR Asset Management S.A., Amundi Ireland Ltd., Amundi SGR SpA (Italy), Amundi Deutschland GmbH (Germany), Amundi Taiwan Ltd., Amundi Investment Fund Management Private Limited Company, Amundi Japan Ltd., SABADELL ASSET MANAGEMENT SA SGIIC, and Amundi Iberia SGIIC SA.

The disclosure does not itemize the specific shareholdings of each subsidiary above reporting thresholds, aligning with German regulatory practice under Section 34 WpHG, which attributes voting rights through controlling chains without detailing sub-holdings unless thresholds are crossed. The extensive Amundi subsidiary network across France, Ireland, Italy, Germany, Taiwan, Japan, Spain, and Hungary underscores the firm’s global asset management reach.

Importance of the 3% WpHG Threshold and Implications for Bayer Investors

German securities law sets the initial mandatory notification threshold at 3% of total voting rights. Crossing this threshold upward or downward requires disclosure, marking a significant milestone in a company’s ownership structure. Amundi’s increase from 2.99% to 3.09% triggered this filing. If Amundi’s stake rises further to 5%, 10%, 15%, 20%, 25%, 30%, 50%, or 75%, additional disclosures will be required.

The immediate impact on Bayer’s share price was not evident from public data. Investors will likely monitor whether Amundi’s position grows further, whether any subsidiaries cross individual reporting thresholds, and if this reflects a broader reassessment of Bayer’s valuation by one of Europe’s largest asset managers. Amundi’s disclosed stake represents aggregated exposure across multiple fund strategies rather than a single portfolio manager’s directional bet.

Bayer’s ISIN DE000BAY0017 and Total Voting Rights of 982,424,082 Shares

The notification references Bayer’s ISIN DE000BAY0017, which identifies its ordinary shares traded on regulated German markets including Frankfurt. This ISIN is the only share class referenced, indicating Amundi’s entire voting rights position relates to ordinary shares. Bayer’s total voting rights, published under Section 41 WpHG, amount to 982,424,082, serving as the denominator for percentage calculations.

This publicly available figure enables verification of shareholding percentages in regulatory filings. Amundi’s 30,375,174 indirectly held shares correspond to the 3.09% disclosed. The 13,770 voting rights from instrument holdings are negligible and do not materially affect Amundi’s overall voting exposure.

Amundi S.A.: Europe’s Largest Asset Manager Expanding Presence in German Blue-Chip Stocks

Amundi S.A. is Europe’s largest asset management firm by assets under management, headquartered in Paris and serving institutional investors, sovereign wealth funds, pension schemes, insurers, and retail clients worldwide. Formed from the 2010 merger of Crdit Agricole and Socit Gnrale’s asset management divisions, Amundi went public on Euronext Paris in 2015. Its subsidiary network, as detailed in this notification, spans multiple continents with specialist investment arms in Italy, Germany, Ireland, Spain, Japan, Taiwan, and Hungary.

Amundi’s stake in Bayer reflects its broader investment focus on large-cap European equities across active and passive strategies. Crossing the 3% threshold in Bayer, a key DAX constituent, is a significant data point for tracking institutional flows into European pharmaceutical and agricultural sectors. The notification does not specify fund strategies or investment rationale, consistent with WpHG disclosure norms.

Regulatory Distribution: EQS News and Europe-Wide Transparency Under WpHG

The notification was distributed via EQS News, a regulated information service of EQS Group, which handles regulatory announcements across European markets. This distribution method complies with WpHG and the European Transparency Directive, ensuring simultaneous availability of major shareholding disclosures to investors across Europe. The announcement confirms its objective of Europe-wide dissemination.

Bayer Aktiengesellschaft, as the issuer, is solely responsible for the announcement content, per standard WpHG practice where the issuer publishes notifications received from reporting parties. Bayer’s LEI is 549300J4U55H3WP1XT59, a unique global identifier facilitating unambiguous regulatory and financial data reporting.

Sector Context: Institutional Ownership Trends Amid Bayer’s Glyphosate Litigation and Pipeline Challenges

Bayer has faced sustained legal and reputational challenges primarily from U.S. litigation related to glyphosate-based herbicides marketed as Roundup, inherited via Monsanto’s 2018 acquisition. These lawsuits have led to significant provisions and settlements, impacting financial performance and share price. Consequently, changes in institutional ownership, such as Amundi’s threshold crossing, are closely watched by analysts and investors evaluating sentiment.

Simultaneously, Bayer’s pharmaceutical pipeline and Crop Science business remain central to its long-term recovery. Investors may track developments in drug development and legal resolutions in the U.S. While Amundi’s increased stake does not indicate a specific investment stance, it represents a material change in Bayer’s voting rights distribution now on public record.

Company-Specific Risks: Litigation Exposure and Financial Provisions at Bayer Aktiengesellschaft

Bayer’s exposure to extensive litigation, especially in the U.S. over glyphosate herbicides allegedly causing cancer, poses significant risk. Multi-billion-dollar settlements and provisions have strained Bayer’s balance sheet and investor confidence. The uncertain outcomes of ongoing and future lawsuits could materially impact Bayer’s financial health and capital allocation to R&D and shareholder returns.

Beyond litigation, Bayer faces typical risks for a multinational pharmaceutical and agricultural company, including regulatory approvals, competitive pressures, currency and geopolitical risks, and operational challenges during structural changes. These factors provide essential context for assessing changes in institutional ownership such as Amundi’s disclosed threshold crossing.
