I would imagine that this funding round would operate under the same pre emption rights as last round - i.e. you wont have any
“In this latest round of fundraising, we have decided to waive pre-emption rights for all previous investors (including institutional investors), in order to prevent the round becoming too large.”
When you think investors “valued” their stake in a company at something like £280,000,000 in November last year and here we are with Investors, 12 months later , who you would have thought must “do” due diligence, now consider their buy in stake to be good value in a company to be “worth” £1,000,000,000 
- or a lucky punt - who knows
