Sanofi's recent acquisition of Blueprint Medicines for $9.1 billion is a significant step in strengthening its rare disease portfolio. This acquisition is expected to be completed in the third quarter and is anticipated to enhance Sanofi's market presence in the rare disease segment, which is projected to have a market size of $2 billion by 2030. This strategic move aligns with Sanofi's focus on expanding its specialty medicine offerings, which already account for a substantial portion of its pharmaceutical sales.

Additionally, Sanofi's Sarclisa treatment for multiple myeloma has shown positive results in a phase III study. The subcutaneous administration of Sarclisa has demonstrated non-inferiority to intravenous administration, offering improved patient satisfaction and supporting regulatory submissions worldwide. This development not only strengthens Sanofi's oncology portfolio but also enhances its competitive edge in the multiple myeloma treatment market.

Moreover, Sanofi's recent launch of its 11th edition of the employee stock ownership plan, allowing employees to purchase shares at a 20% discount, reflects the company's commitment to involving its workforce in its growth journey. This initiative is likely to boost employee morale and align their interests with the company's performance, potentially leading to enhanced productivity and innovation.

1. Strategic Acquisition: Sanofi's acquisition of Blueprint Medicines for $9.1 billion strengthens its rare disease portfolio, with a potential market size of $2 billion by 2030.

2. Positive Clinical Results: Sarclisa's phase III study shows promising results for multiple myeloma treatment, enhancing Sanofi's oncology portfolio.

3. Employee Stock Ownership Plan: Sanofi's 11th edition of the employee stock ownership plan boosts employee engagement and aligns interests with company performance.

Given these positive catalysts, Sanofi's stock is well-positioned for a short-term upswing. I recommend entering a long position at 87.96 EUR, targeting a price of 94 EUR, with a stop loss set at 85.5 EUR.
