• Potential adverse legislative or regulatory tax changes could negatively impact financial condition.
• Product liability lawsuits could result in substantial liabilities and divert resources.
• Misconduct by employees, contractors, or partners could lead to non-compliance with regulatory standards and adverse effects on operations.
• Unfavorable global and geopolitical economic conditions (e.g., inflation, supply chain issues, conflicts) could adversely affect business.
• Health epidemics may affect the ability to initiate/complete studies, disrupt regulatory activities, or impact the supply chain.
• FDA may not accept data from clinical trials conducted outside the U.S.
• Managing obligations under in-license and out-license agreements may divert management attention.
• Interim and preliminary clinical trial results may change as more data becomes available and are subject to audit and verification.
• The stock price may be volatile or decline regardless of operating performance.
• Sales of a substantial number of shares in the public market could cause the stock price to fall.
• Requirements associated with being a public company will increase costs and divert resources.
• The company does not intend to pay dividends for the foreseeable future.
• The company could be subject to securities class action litigation.
• Operating results may fluctuate significantly, making future results difficult to predict.
• Delaware law and corporate provisions could make a merger, tender offer, or proxy contest difficult.

Future Outlook

The company expects to continue incurring significant operating losses for the foreseeable future as it commercializes XDEMVY and advances other product candidates through clinical trials, regulatory submissions, and potential commercialization. It anticipates operating expenses will increase substantially due to continued commercialization efforts, maintaining regulatory approvals, advancing clinical development of TP-04 and TP-05, ensuring sufficient supply chain capacity, expanding intellectual property, hiring additional staff, and adding information systems. The company believes existing capital resources are sufficient for at least the next 12 months but may require additional capital earlier than expected if it pursues additional indications or expands more rapidly. European regulatory approval for a preservative-free XDEMVY formulation is expected in 2027, and meetings with Japanese regulatory authorities for Demodex blepharitis are planned for the second half of 2025. A Phase 2 study for ocular rosacea (TP-04) is planned for initiation in the second half of 2025, and a Phase 2b clinical trial for Lyme disease (TP-05) is expected to initiate in 2026, with a Phase 3 study likely requiring thousands of patients. The company intends to partner the TP-05 program.

Management Comments

• XDEMVY is one of the fastest growing and best-selling launches in the prescription eye drop segment.
• The action-oriented direct-to-consumer advertising campaign is now meaningfully contributing to prescription growth, resulting from new patient engagement and subsequent increase in Eye Care Professionals (ECPs) diagnosing Demodex blepharitis and writing prescriptions.
• Consumers actively engaging on our XDEMVY.com website is up nearly 400% since the beginning of 2025.
• Consumer unaided awareness of XDEMVY has more than tripled since the beginning of the DTC campaign.
• More than 20,000 ECPs are now actively prescribing XDEMVY, a more than 30% increase since the beginning of 2025 and beyond our initial target list of approximately 15,000 ECPs.
• Given the positive results of these trials (Ersa and Rhea for MGD), plus the FDA's feedback that these patients are already covered under XDEMVY's label for the treatment of Demodex blepharitis, our medical affairs team is continuing to move forward with sharing this data with ECPs.
• After review of this data (Galatea trial for TP-04) with the FDA and key opinion leaders, we decided to pursue development of TP-04 for the potential treatment for ocular rosacea, a highly prevalent and underserved eye disease with no FDA-approved therapy.
• We continue to believe that the best approach to get this potential prophylactic therapy (TP-05 for Lyme disease) to patients is to partner this program either prior to the planned initiation of the Phase 2b study or after the completion of the study.
• We believe we are on track for potential European regulatory approval expected in 2027, for a preservative-free formulation of XDEMVY for the potential treatment of Demodex blepharitis.
• In Japan, we plan to meet with regulatory authorities in the second half of 2025 to help determine a regulatory path forward for Demodex blepharitis.
• We believe that our cash, cash equivalents and marketable securities of $381.1 million as of June 30, 2025 and expected sales of XDEMVY is sufficient to fund our current and planned operations for at least the next twelve months from the date of filing this Quarterly Report on Form 10-Q.

Industry Context

Tarsus Pharmaceuticals operates in the highly competitive biopharmaceutical industry, specifically focusing on eye care and infectious disease prevention. The company's flagship product, XDEMVY, is the first FDA-approved therapeutic for Demodex blepharitis, positioning it as a leader in this niche market. The industry is characterized by lengthy and expensive drug development processes, high regulatory hurdles, and intense competition from major pharmaceutical and biotechnology companies. Tarsus's strategy of targeting underserved medical needs (e.g., ocular rosacea, Lyme disease) aligns with a broader industry trend of developing specialized therapies. The company's reliance on third-party manufacturing and single-source suppliers is common in the biotech sector but introduces supply chain risks. The increasing scrutiny on drug pricing and reimbursement, as well as evolving data protection laws, are significant industry-wide challenges that Tarsus must navigate.

Comparison to Industry Standards

• XDEMVY's commercial launch is described as 'one of the fastest growing and best-selling launches in the prescription eye drop segment,' suggesting strong initial market penetration compared to typical new ophthalmic drug introductions.
• The company's ability to secure over 90% commercial, Medicare, and Medicaid reimbursement for XDEMVY indicates successful market access efforts, which is a critical benchmark for new pharmaceutical products.
• The growth in prescribing ECPs (over 20,000, a 30% increase) and consumer engagement (400% increase on website) for XDEMVY demonstrates effective marketing and educational campaigns, potentially outperforming typical adoption rates for novel therapies in a new market segment.
• The gross-to-net discount of approximately 45% for XDEMVY is within the typical range for branded pharmaceutical products in the U.S., reflecting standard industry practices for rebates and discounts.
• The company's accumulated deficit and continued operating losses are typical for a commercial-stage biopharmaceutical company that is heavily investing in commercialization and pipeline development, similar to peers like Aldeyra Therapeutics or Kala Pharmaceuticals in their early commercial phases, which also faced significant SG&A and R&D costs relative to initial revenues.
• The reliance on third-party contract manufacturers and single-source suppliers is a common industry practice, but the risk of supply disruption is a shared concern across the biopharmaceutical sector, as seen with companies like Moderna during the pandemic or various small-cap biotechs facing manufacturing delays for clinical trial materials.

Management Changes

Corporate Governance

Legal Proceedings

• Not currently a party to any material legal proceedings. May become involved in litigation in the ordinary course of business, which could have an adverse impact due to defense/settlement costs, diversion of resources, and negative publicity.

Related Party Transactions

• In April 2024, the company purchased $3.0 million of preferred stock in a privately-held eye care company where its CEO (Dr. Azamian) and a Board member (Dr. Link) also serve as board members. The company owns a small minority stake in this private company.

Stakeholder Impact

• Shareholders: Potential for dilution from future equity raises, but also potential for increased value from successful commercialization and pipeline advancement. Stock price volatility is a risk.
• Employees: Continued growth and expansion of the company's operations, including hiring additional personnel, but also subject to competition for talent and potential impact of macroeconomic conditions.
• Customers (ECPs, patients): Increased access to XDEMVY due to broader reimbursement and effective marketing. Potential for new treatments (TP-04, TP-05) in the future.
• Suppliers/Manufacturers: Continued reliance on third-party manufacturers and single-source suppliers, posing risks if supply is disrupted or costs increase.
• Creditors: Obligations under the 2024 Credit Facility are secured by substantially all company assets, and covenants may limit financial flexibility.

Next Steps

• Continue commercialization of XDEMVY and any other products for which regulatory approvals are obtained.
• Maintain regulatory approval for XDEMVY and seek regulatory approval for other product candidates.
• Advance the clinical development of TP-04 for ocular rosacea, with a Phase 2 study planned for H2 2025.
• Advance the clinical development of TP-05 for Lyme disease prophylaxis, with a Phase 2b clinical trial expected to initiate in 2026.
• Engage with contract manufacturers to ensure sufficient supply chain capacity for commercial quantities of XDEMVY and future products.
• Maintain, expand, and protect the intellectual property portfolio.
• Hire additional staff across clinical, scientific, regulatory, marketing, sales, operations, and finance functions.
• Add information systems and personnel to support product development and commercialization efforts as a public company.
• Seek potential European regulatory approval for a preservative-free formulation of XDEMVY, expected in 2027.
• Meet with regulatory authorities in Japan in H2 2025 to determine a regulatory path for Demodex blepharitis.
• Seek a partnership for the TP-05 Lyme disease program, potentially before or after the Phase 2b study.

Key Dates

Recommendation

The company demonstrates exceptional commercial momentum with XDEMVY, evidenced by a 152% year-over-year increase in product sales and a significant reduction in net losses. The strong cash position provides a solid runway for continued operations and pipeline development. Positive clinical advancements for TP-04 and TP-05, coupled with clear regulatory pathways and international expansion plans, indicate robust future growth potential. While the company still incurs losses and operates in a high-risk industry, the current performance and strategic direction suggest a compelling investment opportunity for growth-oriented investors.
