Freeline Therapeutics Holdings Plc Retention Ratio is NA for the Trailing 12 Months (TTM) ending September 30, 2023. The retention ratio, also known as the plowback ratio, measures the proportion of a company's earnings that are retained after paying dividends. It is calculated by dividing the net income minus dividends paid by the net income. This ratio indicates the percentage of earnings that are reinvested back into the company rather than being distributed to shareholders as dividends. A higher retention ratio suggests a higher level of reinvestment, indicating potential future growth opportunities.
