Xeris Biopharma Holdings (XERS) stock is in focus after the company reported a profitable first quarter of 2026 and raised its full year revenue guidance to US$380 million to US$390 million.

The guidance hike and first quarter profit have come after a mixed period for the stock, with a 12.95% 1 month share price return and a 9.80% year to date share price decline. At the same time, 1 year and 3 year total shareholder returns of 28.49% and around 13x respectively point to stronger longer term momentum.

With shares still below analyst targets and the stock scoring weakly on value metrics, the key question now is whether Xeris Biopharma is trading at a discount or whether the latest guidance hike is already fully reflected in the price.

Most Popular Narrative: 40.5% Undervalued

The most followed valuation work on Xeris Biopharma Holdings currently places fair value at $11.14 per share versus a last close of $6.63, framing a sizable implied gap that depends on how its products and pipeline convert into future cash generation.

Persistent high gross margins, alongside scaling sales of Gvoke, Recorlev, and Keveyis, are viewed as setting the stage for operational leverage and sustainable EBITDA and net margin changes as revenue changes and expense ratios change over time.

Want to see what is behind that confidence in future cash generation? The narrative refers to faster revenue growth, rising margins, and a richer earnings multiple to reach its fair value.

Result: Fair Value of $11.14 (UNDERVALUED)

However, that upside view still runs into real questions around Xeris Biopharma's reliance on just a few commercial products and the cost of advancing its XP-8121 pipeline program.

Another View: High P/E Points to Rich Pricing

That 40.5% implied discount sits alongside a very different message from the P/E ratio. Xeris Biopharma trades on a P/E of 95.3x, compared with a 16.7x industry average, a peer average of around negative 37.2x, and a fair ratio of 25x. This combination signals meaningful valuation risk if expectations slip.
