Citigroup Inc. has crossed the 3% voting rights threshold in Belgian chemical firm Solvay, triggering mandatory transparency notifications under local legislation.

The US banking giant disclosed the position on September 15, 2026, citing acquisitions of financial instruments treated as voting securities.

Notification Details

Citigroup’s latest filing indicates that the threshold was crossed on September 10, 2026. The bank holds no direct voting rights but maintains an equivalent financial instrument position that brings its total exposure to 3.07%.

The notification was filed by a parent undertaking or controlling person. The denominator for the calculation stands at 105,876,416 shares.

Regulatory Context

The disclosure aligns with the Law of May 2, 2007, governing transparency in Belgium. Citigroup noted that the 3% mark represents the lowest threshold stipulated in Solvay’s articles of association.

Solvay, which reported €4.3 billion in net sales for 2025, is listed on Euronext Brussels and Paris. Full details of the holding chain are available on the company’s investor relations website.

Citigroup Inc. has crossed the 3% direct voting rights threshold in Belgian chemical company Solvay, triggering a mandatory transparency notification under the Law of May 2, 2007. The disclosure, filed on August 14, 2026, reveals that Citigroup’s total interest in the company reached 3.04% as of August 11, 2026.

The acquisition was driven by financial instruments treated as voting securities. While Citigroup holds only 0.36% in direct voting rights, its position includes 2.68% in equivalent financial instruments, bringing the aggregate total to just above the regulatory trigger point.

What the Numbers Show

The composition of Citigroup’s holding highlights a reliance on derivative or equivalent instruments rather than direct equity ownership. With equivalent financial instruments constituting approximately 88% of the total reported interest (2.68% out of 3.04%), the bank’s economic exposure is significantly larger than its direct voting power suggests. This structure is common for institutional investors managing risk or exposure through swaps and other derivatives, though it limits direct influence over corporate governance relative to the size of the investment.

Notification Details

The notification specifies that the threshold was crossed upwards on August 11, 2026. The denominator used for calculating the voting rights percentage is 105,876,416 shares. This marks the lowest threshold per Solvay’s articles of association that requires public disclosure.

Citigroup Inc., headquartered at 1209 North Orange Street in Wilmington, Delaware, is listed as the person subject to the notification requirement. The full chain of controlled undertakings through which the holding is effectively held is available on Solvay’s Investor Relations section.
