    The latest FDA approval comes after a volatile few sessions for Vertex Pharmaceuticals, with the share price down 9.32% over the past week but showing a 30 day share price return of 7.94% and a 5 year total shareholder return of 141.04%.

    Most Popular Narrative: 12.3% Undervalued

    Vertex Pharmaceuticals Future Earnings and Revenue Growth

    Assumptions
    How have these above catalysts been quantified?

    • Analysts are assuming Vertex Pharmaceuticals's revenue will grow by 10.0% annually over the next 3 years.

    • Analysts assume that profit margins will increase from 32.9% today to 37.0% in 3 years time.

    • Analysts expect earnings to reach $5.9 billion (and earnings per share of $22.56) by about March 2029, up from $4.0 billion today. However, there is a considerable amount of disagreement amongst the analysts with the most bullish expecting $8.6 billion in earnings, and the most bearish expecting $3.3 billion.

    • In order for the above numbers to justify the price target of the analysts, the company would need to trade at a PE ratio of 28.0x on those 2029 earnings, down from 29.2x today. This future PE is greater than the current PE for the US Biotechs industry at 16.7x.

    • Analysts expect the number of shares outstanding to decline by 1.08% per year for the next 3 years.

    • To value all of this in today's terms, we will use a discount rate of 7.1%, as per the Simply Wall St company report.

    Another View: Vertex Pharmaceuticals Through the Earnings Multiple Lens

    The first fair value view for Vertex Pharmaceuticals leans on long term earnings and discounted cash flows, yet the current P/E ratio of 28.1x tells a different story. It sits well above the US Biotechs industry at 17.4x and even slightly above the 27.8x fair ratio.

    At the same time, that 28.1x P/E is well below the 44.9x peer average. Investors weighing Vertex Pharmaceuticals are looking at a stock that screens expensive against the sector, closer to fairly priced against its own fair ratio, and cheaper than peers. Is that a safety margin or a warning sign around expectations.
