Analysts Are Bullish on Top Healthcare Stocks: Artelo Biosciences (ARTL), Syndax Pharmaceuticals (SNDX)Valuation and Risks. Our $5 PT was derived by using a discount rate of 25% for Artelo shares to discount free cash flows from our projection of annual sales of ART27.13 in cancer anorexia and cachexia syndrome (CACS), 2028-2033, and dividing them by our projected number of shares for each year to account for the effects of share dilution. We then factored in a 2% terminal growth rate, and a 60% clinical program probability of success.
