Tarsus Pharmaceuticals: Unlocking Value Ahead of June Lock-Up Expiration

Tarsus Pharmaceuticals (NASDAQ: TRSS) stands at a pivotal juncture as its June 11, 2025 lock-up expiration approaches, coinciding with a robust execution phase for its lead product XDEMVY and a pipeline primed for clinical milestones. With $135 million raised in its March 2025 equity offering and a cash position of $408 million, the company is positioned to capitalize on underpenetrated markets and emerging catalysts. Here's why investors should consider buying ahead of the unlocking event.

The Lock-Up Expiration: Risk or Opportunity?

The June 11 expiration of a 2.8 million-share lock-up—equivalent to ~12% of Tarsus' outstanding shares—presents a classic liquidity event. While such events often invite near-term volatility, the company's fundamentals and upcoming catalysts suggest this could be a buying opportunity rather than a sell-off catalyst.

Why the upside outweighs the risk:1. Strong Cash Position: The $135 million March offering, combined with Q1 2025's $78.3 million in XDEMVY sales (up 217% YoY), provides ample liquidity to weather potential selling pressure. 2. Proven Execution: Management has consistently delivered on its commercialization roadmap. XDEMVY's market share is growing rapidly, with prescriptions surging 110% among key prescribers since Q3 2024 and DTC campaigns driving a 140% spike in website traffic.3. Catalyst Density: The next six months are packed with value-accretive events, including Phase 2 starts for TP-04 (Ocular Rosacea) and regulatory discussions in Japan and Europe.

The Strategic Use of $135M: Fueling Growth

The March 2025 offering's proceeds are being deployed to accelerate two key initiatives:

1. XDEMVY Commercialization Dominance

• Market Penetration: With 90% of covered lives now reimbursed, Tarsus is focusing on label expansions and geographic expansion. A preservative-free formulation targeting Europe (2027) and Japan (H2 2025 regulatory meetings) could unlock ~$2 billion in additional markets.
• Clinical Validation: New data from the Elara Study (Japan) and Orion Registry reinforce XDEMVY's efficacy in reducing symptoms like fluctuating vision and improving meibomian gland function. These results position the drug as a category leader in anterior segment ophthalmology.

2. Pipeline Advancements: Beyond Blepharitis

• TP-04 (Ocular Rosacea): A Phase 2 trial in H2 2025 could validate a new use case with no FDA-approved treatments. This expands Tarsus' addressable market to ~$500 million in the U.S. alone.
• TP-05 (Lyme Disease Prevention): A 2026 Phase 2 study for this oral tick-killing therapy could open a $2 billion+ niche, leveraging the same mechanism as XDEMVY but in a vastly different therapeutic area.

Bullish Catalyst Timeline: 2025-2026

• Q3 2025: TP-04 Phase 2 trial initiation. Early data could redefine Tarsus' valuation as a multi-indication player.
• Q4 2025: Japan regulatory discussions. Positive feedback here could fast-track approvals in Asia.
• Q1 2026: TP-05 Phase 2 initiation. A successful trial could establish Tarsus in preventive medicine.
• 2027: European approval for preservative-free XDEMVY. Expands usage in sensitive populations.

Valuation and Risks

• Current Valuation: At $44.50/share (March offering price), Tarsus trades at ~3.5x its 2025E sales estimate. If XDEMVY sales hit $400 million by 2026 (a conservative estimate given current growth rates), the stock could re-rate to $80+.
• Key Risks:
• Lock-Up Selling Pressure: Insiders may choose to monetize post-expiration, though the company's insider ownership remains high (founders hold ~25%).
• Regulatory Delays: International approvals could lag, though XDEMVY's safety profile and disease-specific efficacy reduce this risk.
• Competitor Entry: No direct competitors exist yet, but generic or biosimilar threats could emerge in 5+ years.

Investment Thesis: Buy the Dip Ahead of Unlocking

The June 11 lock-up expiration is a short-term catalyst to buy the dip, not sell. Tarsus' cash-rich balance sheet, accelerating XDEMVY adoption, and pipeline progress suggest the stock is undervalued relative to its 2026 growth trajectory. With ~$400 million in cash and a market cap of ~$3.5 billion, the company can easily fund its path to profitability while executing on high-impact catalysts.

Actionable Takeaway: Investors with a 12-18 month horizon should consider accumulating shares at current levels, especially if the stock dips below $40 post-lock-up. The risk-reward here tilts sharply upward, with potential upside to $60-$70 by late 2025 as clinical data and regulatory updates flow in.

In conclusion, Tarsus is a catalyst-driven story with near-term events that could revalue the stock meaningfully. The June lock-up expiration, while a potential short-term headwind, offers a strategic entry point for those willing to bet on execution and market expansion.
