Charlton Athletic's majority shareholder Tahnoon Nimer says he is not looking to sell the Addicks and has reiterated his commitment to the club.
The Syrian businessman, who took over Charlton in January, says documents showing proof of funding have been sent to the English Football League.
Also on Tuesday, it was revealed that Charlton made a pre-tax loss of £10.1m for the year ending June 2019.
That period covers the season in which the club were promoted from League One.
Documents should have been filed at Companies House by 31 March, but Charlton have had an application for an extension accepted because of delays arising from the coronavirus pandemic.
The level of loss for 2018-19 is almost identical to the one reported 12 months previously.
A statement from Charlton's board of directors said: "These are tough times for any professional football club and we are 100% focused on seeing Charlton through this difficult period.
"This will require investment and the first instalment of that investment will come in April."
Nimer's company East Street Investments bought the south-east London club from previous owner Ronald Duchatelet in January.
However, the club are currently under a transfer embargo after ESI failed to provide proof to the EFL of how the Addicks can be funded until June 2021.
Executive chairman Matt Southall and director Jonathan Heller were removed from Charlton's board on 20 March following a falling-out with Nimer, with Bucharest-based pair Marian Mihail and Claudiu Florica appointed in their places.
"The club is not for sale and the majority shareholder, His Excellency Tahnoon Nimer, is not looking for a buyer," the statement added.
"The club has submitted documents for EFL approval to demonstrate the source and sufficiency of funds.
"The club will remain in contact with the EFL with the aim of providing the necessary information as required by the league as soon as possible, so we can successfully conclude matters."
Charlton are in the Championship relegation zone but the 2019-20 season was halted earlier this month because of the coronavirus pandemic, with all football in England suspended until at least 30 April.
