Farhad Moshiri will take his stake in Everton to over 94% after confirming he will buy more shares.
The club's owner is to trigger the option to purchase 33,333 more shares which will see £100m worth of loans turned into equity.
Moshiri will then own 94.1% of shares at Goodison.
In February of last year Moshiri, via Blue Heaven Holdings, bought 66.667% of the 100,000 new shares that were issued - at £3,000 a share - which saw just over £200m of new cash and loan conversions going to the club.

Everton say that today's confirmation of Moshiri committing to buying more shares will improve the balance sheet and give the club better options in the transfer market and with the on-going funding of the new stadium at Bramley-Moore Dock.
Moshiri has already written to other shareholders to confirm his intentions.
The Iranian billionaire, who has written an open letter to supporters this morning, first acquired a 49.9% stake in the club in February 2016 and has gradually increased his share of the club, which now stands at over 94%
