In pursuance of its strategy, Sanofi may acquire technologies and rights to products. Such acquisitions may be made in various contractual forms: acquisitions of shares, loans, license agreements, joint development, and co-marketing. These arrangements generally involve upfront payments on signature of the agreement, development milestone payments, and royalties. Some of these complex agreements include undertakings to fund research programs in future years and payments contingent upon achieving specified development milestones, the granting of approvals or licenses, or the attainment of sales targets once a product is commercialized.

The “Research and development license agreements” line comprises future service commitments to fund research and development or technology, and contingent milestone payments regarded as reasonably achievable (i.e. all potential milestone payments relating to projects in the development phase, for which the future financial consequences are known or probable and for which there is a sufficiently reliable estimate). This line excludes:

•commitments given relating to (i) projects in the research phase, amounting to €16.8 billion as of December 31, 2023 and €18.0 billion as of December 31, 2022 and (ii) payments contingent upon the attainment of sales targets once a product is commercialized, amounting to €17.9 billion as of December 31, 2023 and €18.5 billion as of December 31, 2022);

•commitments received amounting to €10.0 billion as of December 31, 2023 (€8.8 billion as of December 31, 2022), mainly comprising research, development and commercialization agreements with partners further to the acquisitions of (i) Ablynx (€0.9 billion as of December 31, 2023, versus €1.0 billion as of December 31, 2022); (ii) Kymab (€0.2 billion as of December 31, 2023, versus €0.2 billion as of December 31, 2022) and (iii) Provention Bio (€0.3 billion as of December 31, 2023), plus contingent consideration receivable based on attainment of regulatory and sales milestones for commercialized products under the terms of licenses or rights assignment agreements amounting to €8.5 billion as of December 31, 2023 (€7.6 billion as of December 31, 2022).

•on June 19, 2023, Sanofi expanded its collaboration with Scribe Therapeutics signed in September 2022 and entered into an exclusive license agreement on CasX-Editor(XE) genome editing technology associated with guide RNAs for multiple targets including sickle cell disease and other genomic diseases. Under the terms of the agreement, Scribe Therapeutics received an upfront payment of $40 million and may receive more than $1.2 billion based on the achievement of certain milestones;

•on October 3, 2023, Sanofi entered into an agreement with Janssen Pharmaceuticals, Inc. (Janssen), to develop and commercialize the vaccine candidate against extra intestinal pathogenic strains of E. coli developed by Janssen, currently in Phase 3. Under the terms of the agreement, both parties will co-fund current and future research and development costs. Sanofi paid $175 million upfront to Janssen and may pay to Janssen milestone payments contingent on the attainment of certain development and commercial objectives;

•on October 4, 2023, Sanofi entered into a collaboration with Teva Pharmaceuticals to co-develop and co-commercialize asset TEV’574, currently in Phase 2b clinical trials for the treatment of Ulcerative Colitis and Crohn's Disease, two types of inflammatory bowel disease. Under the terms of the new collaboration agreement, Teva received an upfront payment of €469 million ($500 million) and may receive up to €940 million ($1 billion) in milestone payments, depending on the achievement of development and commercialization goals.

In addition, by acquiring all of the outstanding shares of Provention Bio, Inc. on April 27, 2023 (see Note D.1.), Sanofi assumed commitments amounting to €946 million made by that company to various partners under collaboration agreements previously entered into.

The amount of commitments as of December 31, 2023 also includes commitments under agreements entered into by Sanofi in prior years, the principal ones of which are described below. For a full description of each agreement, refer to the Annual Report on Form 20-F for the year in which the agreement was entered into.

•with Exscentia: an innovative license agreement and research collaboration to develop up to 15 novel small molecule candidates across oncology and immunology, leveraging Exscientia’s end-to-end AI-driven platform utilizing actual patient samples;

•with ABL Bio: a licensing and collaboration agreement for the development of ABL301, a bispecific antibody intended as a treatment for alpha-synucleinopathies;

•a strategic risk-sharing collaboration with Blackstone under which funds managed by Blackstone Life Sciences (BXLS) will contribute up to €300 million to accelerate the global pivotal studies and clinical development program for the subcutaneous formulation and delivery of the anti-CD38 antibody SARCLISA, to treat patients with multiple myeloma. That amount will be paid to Sanofi on the basis of development expenses incurred. In addition, Sanofi may pay royalties on future sales of this solution;

•an exclusive collaboration agreement with IGM Biosciences, Inc. to create, develop, manufacture and commercialize IgM antibody agonists against three oncology targets and three immunology/inflammation targets;

Sanofi and one of its alliance partners have decided to terminate the following agreement (the related commitments are no longer included in Sanofi’s off balance sheet disclosures as of December 31, 2023):

•on January 6, 2023, Sanofi and Regulus Therapeutics Inc. terminated their collaboration and license agreement on the discovery, development and commercialization of new micro-RNA derived molecules in fibrosis. The termination took effect on February 5 ,2023.

In addition, under the collaboration agreement with Regeneron on monoclonal antibodies (see Note C.1.), Sanofi is entitled to receive an additional share of quarterly profits (capped at 10% of Regeneron’s share of quarterly profits until March 31, 2022, and thereafter at 20%), until Regeneron has paid 50% of the cumulative development costs incurred by the parties to the alliance. As of December 31, 2023 this represented total commitments received of €2.1 billion (versus €2.7 billion as of December 31, 2022), against cumulative development costs of €8.6 billion.

Sanofi entered into an agreement with Royalty Pharma in December 2014 relating to development programs, under which Royalty Pharma bore a portion of the remaining development costs of the project on a quarterly basis in return for royalties on future sales. The products in development under that agreement have been launched in territories including the United States and Europe, marking the end of the joint development programs.

On February 27, 2017, Sanofi and Lonza announced a strategic partnership in the form of a joint venture (BioAtrium AG) to build and operate a large-scale mammalian cell culture facility for monoclonal antibody production in Visp, Switzerland. An initial investment of approximately €0.3 billion to finance construction of the facility, split 50/50 between the two partners, has now been made in full. In addition, Sanofi could pay BioAtrium AG in the region of €0.6 billion over the 2023-2031 period as its share of operating expenses and the cost of producing future batches.
