When incorporating ESG factors into valuation inputs, a company with strong ESG practices would most likely require the lowest discount rate. This is because strong ESG practices are associated with lower risks, which can lead to more stable and predictable cash flows.

Lower Risk Premium: Companies with robust ESG practices are often perceived as less risky due to better governance, risk management, and sustainability practices. This lowers the risk premium and, consequently, the discount rate.

Stable Cash Flows: Strong ESG practices contribute to long-term sustainability and can lead to more reliable and stable cash flows. This stability justifies a lower discount rate in valuation models.

Positive Market Perception: Companies with strong ESG credentials may enjoy a better reputation and greater investor confidence, which can reduce the cost of capital and support a lower discount rate.
