Why is Bumble not required to disclose it’s Fruitz acquisition?

Bumble (BMBL) just released results and announced they acquired another dating app called Fruitz:

However they are not disclosing the purchase price of this anywhere. As a shareholder I should have this information to determine if they paid a fair price for it or not.

Is this not against GAAP/SEC rules?

Thanks
