The more you read the RNS update the more it is hard to understand the reaction to the share price.
Finally the contract is signed. Ready to go then.
Trump makes his decision so the company now are pausing to just understand that they continue to comply with any US sanctions. Not a big deal.
It has considerable UK Government backing who will not want to be let down by the US position which is contrary to the US, Russia, China and EU stance.
Looking forward to the results in less than a couple of weeks as the company will update further. For traders money to be made.
For investors the big contract is signed and as soon as this sorted, which it will be IMHO then a transformational deal and tags without all the rest of the action going on at the company.
Good luck whatever your position. Personally having researched again am continuing to build my position next week.
