TARS stock is up 7.37% at $89.34 as of the latest trade, driven by the completion of Tarsus Pharmaceuticals’ acquisition of Alkeus Pharmaceuticals. The deal adds gildeuretinol (ALK-001), a Phase 3 oral investigational medicine targeting Stargardt’s disease, a rare form of inherited macular dystrophy. The acquisition expands Tarsus’ leadership in eye care and provides a differentiated therapeutic candidate with potential for regulatory milestones and market differentiation.
Tarsus Pharmaceuticals announced the completion of its acquisition of Alkeus Pharmaceuticals, paying $450 million upfront in cash and stock with up to $350 million in additional milestones. The acquisition includes gildeuretinol, which has demonstrated a 21.6% reduction in retinal lesion growth rate in a 50-patient trial. Alkeus also received Orphan Drug Designation in Japan for gildeuretinol to treat Stargardt disease. The transaction is expected to enhance Tarsus’ portfolio in ophthalmology and provide long-term growth opportunities. Oppenheimer has maintained an Outperform rating on Tarsus and raised its price target to $100.

Trading volume has reached 0.4 million shares, which is 0.5 times the 3-month daily average. Over the past 8 sessions, the stock has risen 17.5%, from $70.72 to $83.11. Tarsus has a market cap of $3.6 billion and reported Q2 revenue of $173.912 million, which beat estimates.
