Madrigal Pharmaceuticals (MDGL) drew fresh attention on July 30, 2026, after reporting second quarter and six month results that showed wider net losses compared with the same periods a year earlier.

The latest results have coincided with pressure on Madrigal Pharmaceuticals' share price, which closed at $467.32 after falling 5.23% on the day and 14.18% over the past week. However, the 1 year total shareholder return of 54.65% points to strong longer term gains that may still be informing how investors weigh growth potential against rising losses.

After a sharp pullback and a run that still leaves Madrigal Pharmaceuticals up strongly over 1 and 3 years, the valuation question gets sharper. Is most of the upside already behind the stock, or could more still lie ahead?

Most Popular Narrative: 31.1% Undervalued

Compared with Madrigal Pharmaceuticals' last close at $467.32, the most widely followed narrative anchors on a fair value near $678.71 and sets out a detailed MASH growth story that hinges on one core drug and a large potential patient pool.

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.

Want to see how this Rezdiffra thesis translates into long range revenue curves, margin rebuilding, and a richer earnings profile? The core assumptions behind that path are bolder than many investors might expect.

Result: Fair Value of $678.71 (UNDERVALUED)

However, this Madrigal Pharmaceuticals upside story still leans heavily on a single drug, while rising competition and reimbursement pressure could limit future pricing power and uptake.
