Day One Biopharmaceuticals has acquired Mersana Therapeutics, enhancing its pipeline with a Phase 1 asset and ADC platform. This strategic move is expected to boost growth prospects and aligns with projected revenue from Ojemda. Despite significant upfront costs, the acquisition won't impact the company's cash flow valuation. The addition of Emi-Le, targeting rare cancers, strengthens Day One's position. Analysts from JonesTrading and Needham maintain a Buy rating, with price targets of $20 and $16, respectively.

In a report released today, Soumit Roy from JonesTrading reiterated a Buy rating on Day One Biopharmaceuticals, with a price target of $20.00.

Soumit Roy’s rating is based on the strategic acquisition of Mersana Therapeutics by Day One Biopharmaceuticals, which is seen as a beneficial move for both companies. The merger provides Day One with a Phase 1 asset in the dose-finding phase, an ADC platform, and the expertise to develop new therapies, which could enhance their pipeline and future growth prospects.
Additionally, the acquisition aligns with Day One’s projected revenue growth from their product Ojemda, expected to generate $150-200+ million in 2025 and 2026. Although the upfront cost of acquiring the ADC platform is significant, it is not expected to affect the company’s discounted cash flow valuation. The addition of Emi-Le, a promising B7-H4 targeting ADC for treating adenoid cystic carcinoma type-1, further strengthens Day One’s position in addressing rare cancers with unmet needs, despite uncertainties in the timing of further data and regulatory meetings.

In another report released today, Needham also maintained a Buy rating on the stock with a $16.00 price target.
