Sanofi completes Kiadis acquisition

Paris, France and Amsterdam, The Netherlands, 16 April 2021 – Sanofi (Euronext: SAN and NYSE: SNY) and Kiadis (Euronext Amsterdam and Brussels: KDS) today jointly announce the successful completion of Sanofi’s acquisition of Kiadis, a clinical-stage biopharmaceutical company developing next generation ‘off-the-shelf’ NK cell-therapies.

Kiadis’ proprietary platform is based on allogeneic or ‘off-the-shelf' NK-cells from a healthy donor. NK-cells seek and identify malignant cancer cells and have broad application across various tumor types. The platform has the potential to make products rapidly and economically available for a broad patient population across a wide range of liquid and solid tumors, and create synergies with Sanofi’s immuno-oncology pipeline.

Kiadis’ NK cell-based medicines will be developed alone and in combination with Sanofi’s existing pipeline and platforms.

The acquisition continues to build on Sanofi’s emerging presence in immuno-oncology aligned with the company’s strategy to pursue best-in-class treatments in defined areas.

As of the Settlement, which has taken place today, Sanofi holds approximately 95.03% of the issued and outstanding share capital of Kiadis on a Fully Diluted basis.

Shareholders who have not yet tendered their Shares will have the opportunity to tender their Shares under the same terms and conditions applicable to the Offer, during the Post-Closing Acceptance Period which started on 14 April 2021 and will end at 17:40 (CET) on 28 April 2021. Sanofi intends to initiate the Buy-Out in an expeditious manner. Reference is made to the joint press release by Sanofi and Kiadis dated 13 April 2021.

Upon Settlement the changes to the composition of the Supervisory Board and Management Board of Kiadis, as approved by the EGM on 30 March 2021, will become effective.

Dutch Translation / Nederlandse vertaling
Parijs, Frankrijk en Amsterdam, Nederland, 16 april 2021 – Sanofi (Euronext: SAN en NYSE: SNY) en Kiadis (Euronext Amsterdam en Brussels: KDS) kondigen gezamenlijk aan de succesvolle afronding van de overname van Kiadis, een biofarmaceutisch bedrijf gericht op de klinische fase dat de volgende generatie “off-the-shelf” NK-celtherapieën ontwikkelt.

Kiadis’ gepatenteerde platform is gebaseerd op allogene, of ‘off-the-shelf’, NK-cellen van een gezonde donor. NK-cellen zoeken en identificeren kwaadaardige kankercellen en hebben een brede toepassing
bij verschillende tumortypen. Het Kiadis platform heeft het potentieel om producten snel en economisch
beschikbaar te maken voor een brede patiëntenpopulatie in een breed scala aan indicaties tegen bloedkanker en vaste tumoren, en om synergiën te creëren met de immuno-oncologie pijplijn van Sanofi.

Kiadis’ NK-celtherapieën zullen als zelfstandige therapie alsmede in combinatie met de bestaande pijplijn en platforms van Sanofi worden ontwikkeld.

De overname bouwt voort op Sanofi's opkomende aanwezigheid in immuno-oncologie, in lijn met de strategie van het bedrijf om de beste behandelingen in bepaalde gebieden na te streven.

Vanaf de Overdracht, die vandaag heeft plaatsgevonden, bezit Sanofi ongeveer 95,03% van het geplaatste en uitstaande aandelenkapitaal van Kiadis op basis van Volledige Verwatering.

Aandeelhouders die hun Aandelen nog niet hebben aangemeld, hebben de mogelijkheid om hun Aandelen aan te melden onder dezelfde voorwaarden als die van toepassing zijn op het Bod, tijdens de Na-aanmeldingstermijn die op 14 april 2021 is begonnen en zal eindigen om 17:40 (CET) op 28 april 2021. Sanofi is voornemens de Uitkoopprocedure op korte termijn te initiëren. Verwezen wordt naar het gezamenlijk persbericht van Sanofi en Kiadis van 13 april 2021.

Bij de Overdracht zullen de wijzigingen in de samenstelling van de Raad van Commissarissen en de Raad van Bestuur van Kiadis, zoals goedgekeurd tijdens de BAVA op 30 maart 2021, van kracht worden.

Sanofi forward-looking statements
This press release contains forward-looking statements as defined in the Private Securities Litigation Reform Act of 1995, as amended. Forward-looking statements are statements that are not historical facts. These statements include projections and estimates and their underlying assumptions, statements regarding plans, objectives, intentions and expectations with respect to future financial results, events, operations, services, product development and potential, and statements regarding future performance. Forward-looking statements are generally identified by the words “expects”, “anticipates”, “believes”, “intends”, “estimates”, “plans” and similar expressions. Although Sanofi’s management believes that the expectations reflected in such forward-looking statements are reasonable, investors are cautioned that forward-looking information and statements are subject to various risks and uncertainties, many of which are difficult to predict and generally beyond the control of Sanofi, that could cause actual results and developments to differ materially from those expressed in, or implied or projected by, the forward-looking information and statements. These risks and uncertainties include among other things, risks related to Sanofi’s ability to complete the acquisition on the proposed terms or on the proposed timeline, the possibility that competing offers will be made, other risks associated with executing business combination transactions, such as the risk that the businesses will not be integrated successfully, that such integration may be more difficult, time-consuming or costly than expected or that the expected benefits of the acquisition will not be realized, the uncertainties inherent in research and development, future clinical data and analysis, including post marketing, decisions by regulatory authorities, such as the FDA or the EMA, regarding whether and when to approve any drug, device or biological application that may be filed for any such product candidates as well as their decisions regarding labelling and other matters that could affect the availability or commercial potential of such product candidates, the fact that product candidates if approved may not be commercially successful, the future approval and commercial success of therapeutic alternatives, Sanofi’s ability to benefit from external growth opportunities, to complete related transactions and/or obtain regulatory clearances, risks associated with intellectual property and any related pending or future litigation and the ultimate outcome of such litigation, trends in exchange rates and prevailing interest rates, volatile economic and market conditions, cost containment initiatives and subsequent changes thereto, and the impact that COVID-19 will have on us, our customers, suppliers, vendors, and other business partners, and the financial condition of any one of them, as well as on our employees and on the global economy as a whole. Any material effect of COVID-19 on any of the foregoing could also adversely impact us. This situation is changing rapidly and additional impacts may arise of which we are not currently aware and may exacerbate other previously identified risks. The risks and uncertainties also include the uncertainties discussed or identified in the public filings with the SEC and the AMF made by Sanofi, including those listed under “Risk Factors” and “Cautionary Statement Regarding Forward-Looking Statements” in Sanofi’s annual report on Form 20-F for the year ended December 31, 2019. Other than as required by applicable law, Sanofi does not undertake any obligation to update or revise any forward-looking information or statements.
