RE: Interims out Monday29 Oct 2021 14:31
I don't think they have to publish the interims by RNS to meet the AIM rules - there are other services that can be used like PR Newswire, which could publish over the weekend. The results can also appear on the website, though I don't think that counts as informing the market.
If they don't publish by the 31st, I believe AIM will suspend then 7am Monday. Even if they then publish 7am Monday, I think the suspension will still stand albeit a notice to resume trading will soon follow.
That would be rather pointless though. Unless there is a serious lights-out problem, I think the results will be out later today.
