Listen to the news

Madrigal Pharmaceuticals (MDGL) is back in focus after publishing a secondary MAESTRO NASH analysis in the Journal of Hepatology, showing Rezdiffra efficacy across common genetic risk variants in metabolic dysfunction associated steatohepatitis.

The latest journal publication lands after a choppy stretch for Madrigal Pharmaceuticals, with the share price down 14.8% over the past 30 days and 22.5% year to date, even as total shareholder return over five years is up almost 5x. This suggests long term momentum remains intact while near term sentiment reacts to shifting expectations around Rezdiffra and the broader MASH opportunity.

Madrigal Pharmaceuticals now has a commercial product, rapid revenue growth and a fresh datapoint on Rezdiffra, yet the share price has slid sharply this year. Is that mix being valued fairly at about $460 a share, or not?

Most Popular Narrative: 32% Undervalued

Against a last close of $460.01, the most widely followed narrative pegs Madrigal Pharmaceuticals' fair value at $678.71, creating a wide gap that hinges on how durable Rezdiffra's opportunity really is.

The rapid uptake and long-term patent protection of Rezdiffra, supported by a new U.S. patent that extends exclusivity to 2045, provides decades of protected revenue opportunity; this increases the likelihood of sustained top-line growth and supports margin expansion due to extended pricing power.

See why 14 investors see Madrigal Pharmaceuticals as 32% undervalued.

Result: Fair Value of $678.71 (UNDERVALUED)

Still, the Madrigal Pharmaceuticals story depends heavily on Rezdiffra, so any disappointing clinical data or slower than expected real world uptake could quickly pressure that undervalued narrative.
