Clarifying required return of equity vs. WACC concepts

CFA Level II Equities
#1

I understand the formulas are different, but let’s say a company has no debt, would the required return of equity be the same as the WACC? Since required return of equity would essentially be the cost of capital for the company, would the two be the same conceptually?

#2

Yes.

If a company has no debt then your WACC = cost of equity

#3

thank you, concepts jumbling up in final days lol
