If the PR contains news that has not been previously disclosed and also has the potential to affect the company's share price once it's made public, then yes, it could fall under the laws covering insider trading.
If the PR that is going to be released early next week only covers the production of Koma Unwind which the shareholders have been made aware, via previous forward looking statements, then that would change things.
Misdirected anger will NOT get the share price to go up.
