Forward Looking Statements
This presentation 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, 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 labeling and other matters that could affect the availability or
commercial potential of such product candidates, the absence of guarantee that the product candidates if approved will
be commercially successful, the future approval and commercial success of therapeutic alternatives, the Group's ability
to benefit from external growth opportunities, trends in exchange rates and prevailing interest rates, the impact of cost
containment initiatives and subsequent changes thereto, the average number of shares outstanding as well as those
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, 2015. Other than as required by applicable law, Sanofi does not undertake any
obligation to update or revise any forward-looking information or statements.

37. 2016 - Headwinds and Tailwinds
● Residual impact of Plavix® generic
erosion in Japan
● Biosimilar insulin glargine launched in
Japan & EU in H2 2015
● Potential generic competition for
Renagel®/Renvela® in the U.S. and
Lovenox® in the EU
● Launch expenses for Toujeo®, Praluent®,
Dengvaxia®, LixiLan(1) and sarilumab
● Immuno-Oncology related expenses
● Low tax rate in H2 2015 creating
unfavorable base for comparison
3737
Headwinds
● Easier base for comparison for Diabetes
and Venezuela(2) in H2 2016
● Stronger Vaccines outlook in H2 2016
● Q4 2015 negatively impacted by
Auvi-Q® and Afrezza®
Tailwinds
(1) LixiLan is a project name and is not the intended brand name for the combination of insulin glargine and lixisenatide
(2) €200m sales in Q2 2015 and €56m in H2 2015
