Net Asset Value

Geiger Counter Limited (LSE: GCL) announces that as at the close of business on 26 March 2026 its unaudited net asset value ("NAV") per ordinary share ("Share") was as follows:

*Notes relating to the NAV dilution

The dilution is in relation to the effect of the Company's embedded annual Subscription Right. Shareholders should note that the dilution refers to the NAV per share dilution, not to the dilution of Shareholders' holdings in the Company. All Shareholders have the right to take up their subscription rights on 1 May in each year and those who do take them up in full don't have their percentage holding in the Company diluted. For those investors who don't take up their subscription rights, the Company endeavours to place in the market the shares that they were entitled to subscribe for, and then return the net sale proceeds to those investors as a way to deliver to them as much as possible of the value of their subscription rights, therefore reducing the dilution effect of not subscribing.

About the annual Subscription Right

Shareholders have the right to subscribe for one new Ordinary Share for every five Ordinary Shares held in the Company on the Record Date, as outlined in the circular published on 31 March 2021. The exercise price is equal to the undiluted NAV per share on 30 April one year prior. The aim of the programme is to enable to Company to grow through share issuance and it is subject to shareholder review at the annual general meeting ("AGM") in 2026 and at every fifth subsequent AGM thereafter.
