Inside the UBS Form 8.3 on Intertek

Global testing, inspection and certification leader Intertek Group plc (LSE: ITRK) is once again in the regulatory spotlight after UBS Asset Management lodged a Form 8.3 dealing disclosure with the market. Published via RNS on 17 June 2026 under reference number 6922I, the filing sets out the asset manager's interests in Intertek's relevant securities as of the dealing date of 16 June 2026.

According to the announcement, UBS Asset Management held 2,151,753 Intertek 1p ordinary shares, equivalent to 1.40% of the relevant class. The total interest line confirms the same 2,151,753 figure and 1.40%, with no cash-settled or stock-settled derivative exposure adding to the position and a reported short position of 0.00%. In other words, this is a clean, long-only equity interest that has crossed the 1% disclosure threshold.

The form notes that the disclosure is made on behalf of a number of UBS Asset Management entities across the UK, Americas, Switzerland, Australia, Singapore, Hong Kong, Taiwan, Japan and Europe, a common structure for large multinational fund managers reporting an aggregated group position.

The Trades Behind the Disclosure

Beyond the headline holding, the Form 8.3 itemises the day's dealings that triggered the filing. UBS recorded a purchase of 201 shares at 56.8 GBP, alongside two sales: 715 shares and 6,743 shares, both at 56.8 GBP. These are modest transactions relative to the multi-million-share total interest, underscoring that the disclosure is driven by the 1%-plus reporting rule rather than by any dramatic shift in stance.

The roughly £56.80 dealing price is well below EQT's mooted £60.00 per share, a gap that is typical during an offer period when a firm bid has not yet been tabled and deal completion remains uncertain.

The EQT Takeover Backdrop

Intertek has been in an offer period, with private-equity group EQT, acting through bid vehicle Isotope Bidco, evaluating a possible all-cash offer of £60.00 per share, valuing the company at approximately £9.2 billion. A 'put up or shut up' deadline of 18 June 2026 framed the timetable for EQT to either announce a firm intention to bid or walk away.

Notably, Intertek has been permitted to pay its 107.7 pence final 2025 dividend without that payment reducing the headline takeover consideration, a detail that matters to shareholders weighing income against deal premium.

Against this backdrop, every Form 8.3 from a major institution such as UBS provides a data point on how sophisticated investors are positioning around a potential change of control.

Why This RNS Matters

Form 8.3 filings are not routine paperwork during an offer period; they are a core transparency mechanism of the UK Takeover Code. Once an investor's interest in any class of relevant securities reaches 1% or more, every subsequent dealing must be disclosed publicly by 3:30pm the following business day.

For Intertek, UBS's 1.40% interest confirms that mainstream institutional money remains engaged with the stock as the EQT situation evolves. Aggregated disclosures like this help the market gauge the free float available to a bidder and the balance of holders who may ultimately decide the fate of any offer.

What Investors Should Watch Next
