Probably just trying to tidy it up the corporate ownership following the takeover
The £54,545,454 shares cancelled equals the previous number of ordinary shares (£30,000,000 NSWE, £24,545,454 recon).
It seems like they recently added 11,000,000 new shares and I would guess split it at the same % as before (55% NSWE, 45% Recon)
FYI Recon / Xia still own an additional £49,133,436 “deferred” shares with no voting rights or dividends. Taking a guess I would assume this has something to do with the “purchase of own shares” and the new number of deferred shares will equal 10,000,000
The end result will be the same except the figures are more rounded
