XGN: Shares Will Rise As Autoimmune Test Adoption Drives 50% Upside Potential

Analysts have lifted their price target on Exagen to $15 from $11, citing a refreshed model that reflects confidence in the company’s autoimmune diagnostics platform and its flagship AVISE CTD test, despite ongoing macro headwinds in the life science tools sector.

Analyst Commentary

Bullish analysts point to Exagen’s specialized focus on autoimmune diagnostics and its AVISE CTD test as key drivers of potential upside, supporting the higher price target and Buy rating in spite of sector-wide pressures.

They highlight that the refreshed valuation models now better reflect the company’s differentiated technology, projected volume growth, and the potential for AVISE CTD to capture a larger share of rheumatology testing as clinical adoption broadens.

Bullish Takeaways

• Bullish analysts see the $15 price target as supported by a more robust revenue trajectory for AVISE CTD, driven by increased clinician awareness and broader utilization in lupus and rheumatoid arthritis workups.
• Exagen’s positioning in a niche, high-need segment of diagnostics is viewed as a competitive moat that can sustain growth above peers and support multiple expansion over time.
• Improving test economics and operating leverage are seen as catalysts for margin expansion, reinforcing the view that earnings power can catch up to and justify the higher valuation.
• The potential for AVISE CTD to become a gold standard tool in autoimmune diagnosis is factored into upside scenarios, with analysts modeling meaningful contribution from both new account wins and deeper penetration of existing rheumatology practices.

Bearish Takeaways

• Bearish analysts remain cautious that macro headwinds in life science tools, including tariff risks and funding uncertainty, could slow ordering patterns and delay the pace at which Exagen can achieve its growth targets.
• Execution risk around commercial expansion, from sales force productivity to payer coverage decisions, is seen as a key variable that could limit near term upside to the current valuation.
• Some models assume ambitious adoption curves for AVISE CTD, and there is concern that any shortfall in rheumatologist uptake or clinical guideline reinforcement could pressure growth estimates.
• Exposure to international and China related dynamics, even if indirect, adds an external risk layer that could compress multiples if sector sentiment for diagnostic and tools companies weakens further.
