Lantheus (LNTH): Reassessing Valuation After Recent Share Price Rebound

Simply Wall St·12/12/2025 11:23:26
Listen to the news

Lantheus Holdings (LNTH) has quietly rebounded, with shares up about 19% over the past month even though the stock is still down roughly 31% over the past year, resetting expectations around its valuation.

See our latest analysis for Lantheus Holdings.

That rebound fits into a more mixed picture, with a strong 30 day share price return alongside a weak year to date move. At the same time, longer term total shareholder returns still look compelling, suggesting sentiment may be stabilizing rather than collapsing.

If Lantheus price action has you reassessing the healthcare space, it is a good moment to scan other opportunities across healthcare stocks and see what else stands out.

With shares still well below their highs despite solid revenue and profit growth, plus a sizable gap to analyst targets, the key question now is whether Lantheus is genuinely undervalued or if the market already anticipates its next leg of growth?

Most Popular Narrative Narrative: 22.0% Undervalued

With Lantheus last closing at $63.10 against a narrative fair value near $80.93, the story centers on whether future earnings can close that gap.

Multiple new product launches within the next 18 months, including the new F-18 PSMA PET, MK-6240, OCTEVY, and PNT2003, are set to diversify the revenue base, mitigate concentration risk, and open additional growth channels in oncology and neuroendocrine tumor imaging, supporting both top-line and future earnings expansion.
