the expected return on the stock will decrease
Explanation:
total firm's value $100 million
required rate of return:
if the firm issues new stock and retires debt:
The return on equity (ROE) measures how much money a company earns per dollar invested, ROE formula = net income / total equity
now let's suppose that the firm's net income is $10 million:
under the old capital structure ROE = $10 / $68 = 14.7%
now under the new capital structure net income will increase by the amount of interests saved = $21 x 7.2% = 1.512
new net income = $11.512
new ROE = $11.512 / $89 = 12.9%
following this example, the new ROE will be 12.2% lower than before because the cost of debt was much lower than the cost of equity.
as the weight of equity increases, the company's WACC will increase also:
