How will Corona Virus effect the equity valuation methods we are able to use?

Hi all, hope you're well. I have been thinking that during this corona virus epidemic a lot of companies are suspending their dividend payments and am trying to understand in detail how this will effect the validity of the Gordon Growth Model - will it still hold true? Or instead will other valuation techniques such as Residual Income and Economic Valuation need to be considered?

Very grateful if anyone has an opinion on this they'd like to share.

Thanks,

:D
