Ann: App 2A - Application for Quotation on Exercise of Options, page-6

Page 14 of the half-yearly report released on 17-Feb-2021 shows cash received from the exercise of options. The issue of shares in return for money is a capital transaction so it's listed separately from revenue.

Also you'll see from the same page that only 800,000 new options were issued in the second half of 2020, compared to over 20 million in the same half of 2019, which seems to me like a reasonable reflection of the company's performance.
