Is Ionis Pharmaceuticals, Inc. overvalued or undervalued?

As of 22 February 2023, the valuation grade for Ionis Pharmaceuticals, Inc. has moved from fair to risky, indicating a more cautious outlook. The company appears to be overvalued given its current financial metrics, particularly with a Price to Book Value of 11.81 and a troubling ROE of -94.65%. Additionally, the EV to Sales ratio stands at 7.34, suggesting that the market may be pricing in expectations that are not supported by the company's current performance.
In comparison to its peers, Ionis Pharmaceuticals has a significantly lower EV to EBITDA ratio of -11.71, while Neurocrine Biosciences, Inc. is considered expensive with an EV to EBITDA of 25.2794.
