Yellowknife Mining has 80 million shares that are currently trading for $4 per share and $110 million worth of debt. The debt is risk free and has an interest rate of 6%, and the expected return of Yellowknife stock is 14%. Suppose a mining strike causes the price of Yellowknife stock to fall 23% to $3. 08 per share. The value of the risk-free debt is unchanged. Assuming there are no taxes and the risk (unlevered beta) of Yellowknife's assets is unchanged, what happens to Yellowknife's equity cost of capital? Equity cost of capital is \%.
