Methodology
Notes. Raised is the sum of shares allotted times price per share across priced allotments filed on form SH01. Peak step-up is the highest price per share divided by the first priced round. Implied post-money is price per share times shares in issue after the allotment: an approximation that ignores class rights and unexercised options. Allotments classified as option-scheme or nominal issues are excluded from the trajectory.Primary documents
