About XDEMVY^®
XDEMVY (lotilaner ophthalmic solution) 0.25%, formerly known as TP-03, is a novel prescription eye drop designed to treat Demodex blepharitis by targeting and eradicating the root cause of the disease – Demodex mite infestation. XDEMVY was evaluated in two pivotal trials collectively involving more than 800 patients. Both trials met the primary endpoint and all secondary endpoints, with statistical significance and no serious treatment-related adverse events. Most patients found the XDEMVY eye drop to be neutral to very comfortable. The most common ocular adverse reactions observed in the studies were instillation site stinging and burning which was reported in 10% of patients. Other ocular adverse reactions reported by less than 2% of patients were chalazion/hordeolum (stye) and punctate keratitis.

XDEMVY Indication and Important Safety Information

INDICATIONS AND USAGE

Most common side effects: The most common side effect in clinical trials was stinging and burning in 10% of patients. Other side effects in less than 2% of patients were chalazion/hordeolum and punctate keratitis.

About TP-03
TP-03 (lotilaner ophthalmic solution) 0.25% is a novel therapeutic designed to treat Demodex blepharitis by targeting and eradicating the root cause of disease – Demodex mite infestation. It was approved by the FDA in 2023 under the brand name XDEMVY® for the treatment of Demodex blepharitis. Lotilaner is a well characterized anti-parasitic agent that paralyzes and eradicates Demodex mites by selectively inhibiting parasite-specific gamma-aminobutyric acid-gated chloride (GABA-Cl) channels. It is a highly lipophilic molecule, which may promote its uptake in the oily sebum of the eyelash follicles where the mites reside.

About TP-04
TP-04 is an investigational sterile aqueous gel formulation of lotilaner. Tarsus is studying TP-04 for the potential treatment of ocular rosacea (OR).

About TP-05
TP-05 is an investigational oral systemic formulation of lotilaner. TP-05 is believed to be the only non-vaccine, drug-based, preventative therapeutic in development designed to kill ticks to potentially prevent Lyme disease transmission.

About Tarsus Pharmaceuticals, Inc.
Tarsus Pharmaceuticals, Inc. applies proven science and new technology to revolutionize treatment for patients, starting with eye care. Tarsus is advancing its pipeline to address several diseases with high unmet need across a range of therapeutic categories, including eye care, dermatology, and infectious disease prevention. XDEMVY (lotilaner ophthalmic solution) 0.25% is FDA approved in the United States for the treatment of Demodex blepharitis. Tarsus is also developing TP-04 for the potential treatment of ocular rosacea and TP-05 as an oral tablet for the potential prevention of Lyme disease, all of which are in Phase 2.

Forward-Looking Statements
Statements in this press release about future expectations, plans and prospects, as well as any other statements regarding matters that are not historical facts, may constitute “forward-looking statements.” These statements include statements regarding our 2026 financial outlook, the potential commercial success and growth of XDEMVY in Demodex blepharitis, including market size, peak net product sales potential, acceptance, demand, and adoption rate for XDEMVY; our ability to successfully continue our direct-to-consumer campaign; our ability to achieve and maintain distribution and patient access for XDEMVY and breadth of payer coverage; our ability to continue to educate the market about Demodex blepharitis; our ability to initiate planned clinical studies including the planned initiation of a Phase 2 trial for the potential prevention of Lyme disease; anticipated regulatory and development milestones including potential Europe, China, and Japan regulatory pathways and approval for TP-03; the results of our clinical studies; the test results of our pipeline formulations; our ability to continue investing in our business and actively evaluate external opportunities, and the quotations of Tarsus’ management. The words, without limitation, “believe,” “contemplate,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “potential,” “predict,” “project,” “should,” “target,” “will,” or “would,” or the negative of these terms or other similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these or similar identifying words. Actual results may differ materially from those indicated by such forward-looking statements as a result of various important factors. Important factors that could cause actual results to differ materially from those in the forward-looking statements include: Tarsus is heavily dependent on the successful commercialization of XDEMVY for the treatment of Demodex blepharitis and the successful development, regulatory approvals and commercialization of its current and future product candidates; Tarsus’ ability to obtain and maintain regulatory approval for and successfully commercialize its products, including XDEMVY for the treatment of Demodex blepharitis, and its product candidates to meet existing and future regulatory standards; Tarsus has incurred significant losses and negative cash flows from operations since inception and anticipates that it could continue to incur significant expenses and potential losses in the future; Tarsus’ capital requirements are difficult to predict and may change; Tarsus may need to obtain additional funding to achieve its goals and a failure to obtain this necessary capital when needed on acceptable terms, or at all, could force Tarsus to delay, reduce, or eliminate its product development programs, commercialization efforts or other operations; Tarsus may not ultimately be successful in educating healthcare professionals and the market about the need for treatments specifically for Demodex blepharitis and other diseases targeted by XDEMVY or our product candidates; the development and commercialization of Tarsus’ products and its product candidates is dependent on intellectual property it licenses from Elanco Tiergesundheit AG; Tarsus expects to expand its development, regulatory, operational, sales, marketing, and distribution capabilities and Tarsus may encounter difficulties in managing its growth, which could disrupt its operations; the sizes of the market opportunity for XDEMVY and Tarsus’ product candidates, particularly TP-04 for the potential treatment of ocular rosacea, as well as TP-05 for the potential prevention of Lyme disease, have not been established with precision and may be smaller than estimated, possibly materially; the results of Tarsus’ earlier studies and trials may not be predictive of future results; any termination or suspension of, or delays in the commencement or completion of, Tarsus’ planned clinical trials could result in increased costs, delay or limit its ability to generate revenue from net product sales and adversely affect its commercial prospects; if Tarsus is unable to obtain and maintain sufficient intellectual property protection for XDEMVY or its product candidates, or if the scope of the intellectual property protection is not sufficiently broad, Tarsus’ competitors could develop and commercialize products similar or identical to Tarsus’ products; and if Tarsus is unable to access capital (including but not limited to cash, cash equivalents, and credit facilities) and/or loses capital, as a result of potential failure of any financial institutions that Tarsus does business with directly or indirectly. Further, there are other risks and uncertainties that could cause actual results to differ from those set forth in the forward-looking statements and they are detailed from time to time in the reports Tarsus files with the Securities and Exchange Commission, including Tarsus’ Form 10-K for the year ended December 31, 2025 planned to be filed on February 23, 2026, copies of which are or will be posted on its website and are available from Tarsus without charge. However, new risk factors and uncertainties may emerge from time to time, and it is not possible to predict all risk factors and uncertainties. Accordingly, readers are cautioned not to place undue reliance on these forward-looking statements. Any forward-looking statements contained in this earnings release are based on the current expectations of Tarsus’ management team and speak only as of the date hereof, and Tarsus specifically disclaims any obligation to update any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by law.
