Listen to the news

Nektar Therapeutics (NKTR) is drawing attention after recent trading left the share price at US$57.06, with the stock down 4% on the day and weaker over the past month.

Nektar Therapeutics has seen momentum fade in recent weeks, with the share price return down 21.32% over the past month and 18.26% over 90 days. This comes even though the year-to-date share price return is still up 31.41%, the 3-year total shareholder return is very large, and the 5-year total shareholder return remains down 79%.

For Nektar Therapeutics, a sharp pullback after a strong year-to-date gain raises a simple issue. Is the latest slide pointing to cracks in the business, or is it simply resetting sentiment before investors reassess valuation?

Most Popular Narrative: 60.5% Undervalued

On the most followed view, Nektar Therapeutics screens as materially cheaper than an estimated fair value of $144.40, with the narrative built around late stage trial progress and a long cash runway rather than near term profitability.

Robust cash position after the recent equity raise extends runway into 2027, providing operational stability to advance late-stage assets and initiate Phase III trials without near-term dilution or financing risk, which supports earnings predictability and reduces financial leverage concerns.

See why 13 investors see Nektar Therapeutics as 60% undervalued.

Result: Fair Value of $144.40 (UNDERVALUED)

Still, Nektar Therapeutics remains heavily tied to rezpeg outcomes, and ongoing losses with no approved products could pressure that cash runway faster than bullish investors expect.

Another View on Nektar Therapeutics Valuation

The popular narrative has Nektar Therapeutics looking 60.5% below a fair value of $144.40, yet the current market tag tells a different story. On a simple P/S basis, NKTR trades at 35.7x sales versus 4.8x for the wider US Pharmaceuticals group and 15.3x for closer peers.

That is more than double the peer average and over three times the sector, while the fair ratio sits at 11.2x. If the share price ever drifted closer to that fair ratio, the adjustment would come from a much lower multiple rather than a higher one, which sets up a very different kind of risk dial for investors to consider.
