You have calculated the unlevered beta of Adobe as 0.79 (actually, this is the answer of the question posted on the 4th of January, 2025. If your estimate were different from that value in higher orders of magnitude, you should check your model and assumptions).
Adobe’s cost of debt is estimated to be 3% as of August 2024.
For the risk-free rate, use the current yield on 10-year US Treasuries (9th of August, 2024).
Equity risk premium will be 6.5%. Corporate tax rate for Adobe is 21%.
You want to investigate how the WACC of Adobe will change in changing capital structures.
Assume that the cost of debt for Adobe does not increase with the amount of debt in the capital structure (seemingly not realistic but there are such cases; do you know why?).
Investigate how the cost of equity and WACC will change with changing debt-to-assets ratios, i.e. start from 0% and incrementally increase it by 15% and stop when the ratio hits 90%.
Plot the cost of equity, cost of debt, and WACC at changing debt to asset ratios!
