SThree Purchases 16,624 Shares Through Berenberg Under Its February 2026 Buyback Programme

SThree executed the buyback through Berenberg on 12 November 2026, conducting 16 individual trades across the London Stock Exchange's XLON venue, the announcement states. Prices across those trades ranged from a session low of 299.5 pence to a high of 305 pence per share, with the weighted average settling at 300.6616 pence. The buyback programme was originally announced on 12 February 2026, and the company confirmed that all purchased ordinary shares will be cancelled rather than held in treasury, which over time reduces the total number of shares in circulation.

Sharesave Scheme Issue and Updated Total Voting Rights Following 12 November Transactions

Alongside the buyback, SThree also disclosed that on 11 November 2026 it issued 1,835 ordinary shares pursuant to option exercises under its Sharesave scheme. After accounting for both the new issuance and the buyback purchases, the company's total shares in issue stand at 121,293,112. With 35,767 shares held in treasury and therefore excluded, the total voting rights figure is confirmed at 121,257,345. The announcement states shareholders may use this denominator to assess whether they are required to notify interests under the FCA's Disclosure Guidance and Transparency Rules.

Rule 2.9 Disclosure Confirms SThree Remains in Offer Period Following 9 September 2026 Announcement

The announcement includes a formal Rule 2.9 disclosure under the City Code on Takeovers and Mergers, confirming that SThree entered an offer period on 9 September 2026. Under the Code, the company's ordinary shares are classified as relevant securities for Rule 8 purposes, requiring regular public disclosure of share capital figures. SThree confirms its ISIN is GB00B0KM9T71 and its LEI is 2138003NEBX5VRP3EX50. Each ordinary share carries one vote. Investors following the offer period will be watching for any further regulatory disclosures or developments under the Code as the situation progresses.

Ongoing Buyback and Offer Period Create a Dual Focus for SThree Shareholders to Monitor

SThree operates as a staffing business focused on placing professionals in science, technology, engineering, and mathematics roles, with international operations across multiple markets. The simultaneous operation of a share buyback programme and an active offer period creates a notable regulatory and corporate governance backdrop for shareholders to monitor. The cancellation of repurchased shares is a shareholder-value mechanism that reduces the dilutive effect of ongoing equity schemes such as Sharesave. Investors may be watching for further announcements regarding the offer period or updates to buyback volumes in the coming weeks.
