Thesis Summary

Tarsus Pharmaceuticals is a high-growth commercial-stage biopharmaceutical company with a validated category-creating asset in XDEMVY, the first and only FDA-approved treatment for Demodex blepharitis. With a massive addressable market of 25 million patients in the U.S. and strong commercial execution, XDEMVY is on a clear trajectory toward blockbuster status with peak sales potential exceeding $2 billion. The company's robust cash position of approximately $389 million provides a comfortable runway through projected profitability in 2027, minimizing dilution risks. Furthermore, the pipeline features high-potential Phase 2 assets (TP-04 for ocular rosacea and TP-05 for Lyme disease prevention) that offer significant valuation upside with major clinical catalysts expected in the first half of 2027.

Bear CaseDownside scenario

XDEMVY sales growth decelerates due to persistent seasonal headwinds, deductible resets, or higher-than-expected gross-to-net discounts. Payer pushback or competitive alternatives limit market penetration. Clinical setbacks or safety concerns emerge in the Phase 2 trials for TP-04 or TP-05, limiting the company's long-term pipeline valuation.

Base CaseCentral scenario

XDEMVY continues its steady commercial trajectory, meeting the FY 2026 net product sales guidance of $670 million to $700 million with strong gross margins of ~93%. The company achieves profitability by 2027 as operating leverage kicks in. Phase 2 trials for TP-04 and TP-05 progress on schedule with positive topline data in H1 2027, validating the broader lotilaner platform.

Bull CaseUpside scenario

XDEMVY adoption accelerates rapidly beyond expectations, driven by highly effective DTC campaigns and deeper penetration among eye care professionals (ECPs). International commercialization, particularly in China following the recent TP-03 approval and $15 million milestone, scales faster than anticipated. Pipeline readouts for TP-04 and TP-05 in H1 2027 demonstrate best-in-class efficacy, positioning Tarsus as a multi-blockbuster franchise.

Scenarios are anchored to street consensus at the research date, with our probabilities and rationale.
