Most Popular Narrative: 4% Undervalued

According to AHaron's widely followed narrative, Eli Lilly's fair value of $1,477.03 sits modestly above the last close at $1,417.54, which points to a mild undervaluation built on specific growth and pipeline assumptions rather than broad market optimism.

The model uses four inputs to arrive at the fair value: a growth rate that 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, based on an 18% growth rate and stable margins.

See why 80 investors see Eli Lilly as 4% undervalued.

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

Still, Eli Lilly’s story can change quickly if GLP-1 pricing pressure intensifies or if key late stage trials fail to match current expectations.
