Most Popular Narrative: 15% Undervalued

The most followed valuation narrative for Eli Lilly points to a fair value above the last close of $1,255.40, which suggests a pricing gap that some investors view as meaningful.

The model uses four inputs to arrive at the fair value: growth rate, which has been adjusted to 18% to reflect reality rather than the overly conservative 12.71% default; a future PE ratio of 30 times earnings in 2031, down from today's 39 times, which accounts for the natural compression in valuation multiples as a company matures and grows larger; a discount rate of 7.5%, slightly above the default of 6.98%, to account for the pipeline risks that still exist; and earnings by 2031 of approximately $48 to $50 billion, above the model's $41.5 billion, because at 18% growth and stable margins, that is where the numbers land.

Read the complete narrative.

Curious how Eli Lilly gets from today’s earnings to that higher fair value range? The narrative leans on profit expansion, firm margins and a rich future multiple. The exact mix of those inputs is what really shifts the valuation story.

Result: Fair Value of $1,477.03 (UNDERVALUED)

However, Eli Lilly’s story could shift quickly if pricing pressure on GLP 1 drugs intensifies or key pipeline trials deliver weaker than expected outcomes.

Another View on Eli Lilly’s Valuation

While the most popular Eli Lilly narrative leans on a detailed earnings model, the market price also reflects what investors pay for each dollar of current earnings. On this measure, Eli Lilly trades on a P/E of 41.9x, compared with 16.8x for the US pharmaceuticals industry and a fair ratio of 40.5x that the market could move towards.

This P/E is below the peer average of 50.3x, which hints at some relative value, yet it still sits above the fair ratio, which implies less room for error if sentiment cools. The question for investors is whether Eli Lilly’s current growth and pipeline justify paying this much more for each dollar of earnings.
