Sanofi Delivers 2016 Sales and Business EPS(1) Gro

Paris, February 8, 2017

Sanofi Delivers 2016 Sales and Business EPS ⁽¹⁾ Growth at CER ⁽²⁾

Following the announcement of exclusive negotiations with Boehringer Ingelheim and as per the IFRS 5 presentation requirement for discontinued operations, net income for Sanofi's Animal Health business (Merial) was reported on a separate line ("Net income from the held for exchange Animal Health Business") in the Consolidated Income Statement for 2016 and the prior year. In the first three quarters of 2016, Sanofi comments included Merial for every income statement line using the term "Aggregate". Sanofi neither presents "Aggregate" figures nor reports Animal Health business as an operating segment in Q4 2016 and in 2016 as a result of the closing early in 2017 of the swap of the Animal Health/CHC business with Boehringer Ingelheim. 2016 net sales including Animal Health ⁽³⁾ were €36,529 million of which €9,466 million in the fourth quarter of 2016.

(1) In order to facilitate an understanding of operational performance, Sanofi comments on the business net income statement. Business net income is a non-GAAP financial measure (see Appendix 11 for definitions). The consolidated income statement for Q4 2016 and 2016 is provided in Appendix 4 and a reconciliation of business net income to IFRS net income reported is set forth in Appendix 3; (2) changes in net sales are expressed at constant exchange rates (CER) unless otherwise indicated (see Appendix 11); (3) Merial information is provided in appendix 5; (4) See page 8; (5) 2016 Business EPS was €5.68.

2016 fourth-quarter and full-year Sanofi sales

In the fourth quarter of 2016, Company sales were €8,867 million, up 3.3% on a reported basis. Exchange rate movements had a negative effect of 0.1 percentage points. At CER, Company sales increased 3.4%.

In 2016, Company sales were €33,821 million, down 0.7% on a reported basis. Exchange rate movements had an unfavorable effect of 1.9 percentage points reflecting mainly the adverse evolution of the Argentine Peso, Chinese Yuan, Mexican Peso and British Pound, which more than offset the positive effects from the Japanese Yen. At CER, Company sales increased 1.2%.

2016 performance included a negative currency impact related to the change of exchange rate applied for the translation of Venezuela operations, resulting from the evolution of the exchange system in February 2016 as well as from the persistent inability to exchange Venezuelan bolivars for U.S. dollars at the privileged official rate. In addition, in the first half of 2015, Sanofi benefited from a significant increase in product demand in Venezuela, due to buying patterns associated with local market conditions. As a consequence, sales in Venezuela were €18 million in 2016 compared to €455 million in 2015. Excluding Venezuela, Company sales increased 3.7% and 2.6% in the fourth quarter and in 2016, respectively.

Oncology franchise

Fourth-quarter Oncology sales decreased 3.9% to €369 million. Growth of Jevtana ^® , Thymoglobulin ^® and Mozobil ^® was offset by lower Taxotere ^® and Eloxatin ^® sales. In 2016, Oncology sales were €1,453 million, down 2.2%.

Jevtana ^® sales were up 8.3% to €92 million in the fourth quarter led by Europe (up 12.5% to €35 million) and Japan. Full-year Jevtana ^® sales were up 11.5% to €358 million.

In the fourth quarter, Thymoglobulin ^® sales were up 10.1% to €77 million supported by the performance in the U.S. (up 16.2% to €43 million). In 2016, Thymoglobulin ^® sales were up 10.9% to €281 million.

Fourth-quarter Eloxatin ^® sales were down 27.6% to €41 million reflecting generic competition in Canada. Over the same period, Taxotere ^® sales decreased 12.2% (to €42 million) due to continuous generic competition in Japan. In 2016, Taxotere ^® and Eloxatin ^® sales were down 17.1% (€179 million) and 21.6% (€170 million), respectively.

Diabetes franchise

(a) Excluding Venezuela: -1.2%;

In the fourth quarter, Diabetes sales increased 1.9% to €1,945 million, including lower Lantus ^® sales in the U.S. Fourth-quarter U.S. Diabetes sales were up 5.5% to €1,131 million.

Fourth-quarter sales of Sanofi glargine (Lantus ^® and Toujeo ^® ) increased 3.5% to €1,701 million. In the U.S., Sanofi glargine sales of €1,100 million were up 7.0%. In Europe, Sanofi glargine sales decreased 5.4% to €240 million due to biosimilar competition in several European markets. In 2016, Sanofi glargine sales were €6,363 million, down 1.8%.

Over the quarter, Lantus ^® sales were €1,463 million down 5.1%. In the U.S., Lantus ^® sales decreased 1.8% to €931 million mainly reflecting lower average net price and patients switching to Toujeo ^® . In Europe, fourth-quarter Lantus ^® sales were €199 million (down 17.4%) due to biosimilar competition and patients switching to Toujeo ^® . In Emerging Markets, sales were stable at €243 million impacted by lower sales in Russia. In 2016, Lantus ^® sales were €5,714 million, down 9.4%.

Fourth-quarter Toujeo ^® sales were €238 million of which €169 million were recorded in the U.S. and €41million in Europe. The global roll-out of this product continues and Toujeo ^® is available in 45 countries. In Japan, the two-week prescription limit was lifted in September 2016, resulting in a significant increase in market share (10.8% in December 2016- based on IMS basal insulin share market in value). Full-year Toujeo ^® sales were €649 million (versus €164 million in 2015).

Amaryl ^® sales were €89 million, down 1.1% in the fourth quarter, of which €73 million were generated in Emerging Markets (up 4.1%). In 2016, Amaryl ^® sales were €362 million, down 3.8%.

Fourth-quarter Apidra ^® sales decreased 9.6% to €95 million, reflecting lower sales in the U.S. (down 31.0% to €29 million) and Europe (down 6.1% to €32 million), which offset the performance in Emerging Markets (up 33.3% to €22 million). In 2016, Apidra ^® sales decreased 1.1% to €367 million.

Since January 2017, Soliqua (TM) 100/33 (insulin glargine 100 Units/mL & lixisenatide 33 mcg/mL injection; lixisenatide was in-licensed from Zealand Pharma) has been available in the U.S. Soliqua 100/33 is indicated for the treatment of adults with type 2 diabetes inadequately controlled on basal insulin (less than 60 Units daily) or lixisenatide. Sanofi is offering Soliqua(TM) 100/33 at a $0 co-pay (see press release from January 4, 2017) for eligible U.S. patients with commercial insurance and is working to secure market access from payers. Sanofi is also offering a tailored support program, Soliqua(TM) 100/33 COACH, at no cost to patients who have been prescribed the product.

Cardiovascular franchise

Praluent ^® (alirocumab, collaboration with Regeneron) was launched in the U.S., in a number of European markets and Japan in 2015 and 2016. Fourth-quarter Praluent ^® sales were €37 million of which €30 million were in the U.S. and €6 million in Europe. Full-year Praluent ^® sales were €105 million reflecting significant payer utilization management restrictions in the U.S. and limited market access in Europe.

In January 2017, the U.S. District Court for the District of Delaware issued an injunction that requires Sanofi and Regeneron to stop marketing, selling and manufacturing Praluent ^® in the U.S. starting from February 21, 2017. Until that date, Praluent ^® remains available in the U.S. Sanofi and Regeneron filed a motion with the United States Court of Appeals for the Federal Circuit to stay (suspend) the injunction pending the appeal of the judgment upholding the validity of Amgen's patents for antibodies targeting PCSK9 as well as the injunction ruling.

Fourth-quarter and 2016 Multaq ^® sales were €94 million (up 10.6%) and €353 million (up 3.8%), respectively.

Established Rx Products

(a) Excluding Venezuela: -1.1%; (b) Excluding Venezuela: -17.1%; (c) Excluding Venezuela: -0.7%; (d) Excluding Venezuela: +0.5%; (e) Excluding Venezuela: -2.3%; (f) Excluding Venezuela: -3.2%; (g) Excluding Venezuela: -4.9%;

In the fourth quarter, Established Rx Products sales decreased 1.3% to €2,568 million, reflecting generic competition to Plavix ^® in Japan, and the low basis for comparison from the recall of Auvi-Q ^® in the fourth quarter of 2015. In Emerging Markets, Established Rx Products sales increased 0.9% to €946 million driven by the performance of Lovenox ^® . In the U.S., Established Rx Products sales increased 22.4% (to €371 million) mainly due to the low basis for comparison from the recall Auvi-Q ^® in the prior period. In Europe, Established Rx Products sales decreased 3.3% to €911 million. Full-year Established Rx Products sales decreased 6.8% to €10,311 million and 4.9% excluding Venezuela.

Lovenox ^® sales increased 0.7% to €414 million in the fourth quarter, driven by strong performance in Emerging Markets (up 12.2% to €124 million), which offset the impact of generic competition in the U.S. (down 27.8% to €13 million) and lower sales in Europe (down 1.5% to €255 million). In September, two enoxaparin biosimilars were approved in the European Union. In 2016, Lovenox ^® sales were €1,636 million, down 1.7%.

In the fourth quarter, Plavix ^® sales were down 20.0% to €363 million due to generic competition in Japan that started in June 2015 (sales in Japan were down 49.3% to €82 million). In 2016, Plavix ^® sales decreased 18.8% to €1,544 million.

Fourth-quarter Renvela ^® /Renagel ^® sales decreased 2.5% to €235 million.  In the U.S. where Sanofi expects generic competition in the first half of 2017, fourth-quarter sales were down 0.5% to €194 million. In Europe, Renvela ^® /Renagel ^® sales were down 24.0% to €19 million due to generic competition. Full-year Renvela ^® /Renagel ^® sales were down 1.1% to €922 million.

Aprovel ^® /Avapro ^® sales were down 1.8% (to €163 million) and down 7.0% (to €681 million) in the fourth quarter and the full year, respectively.

In the fourth quarter of 2015, Sanofi recalled Auvi-Q ^® /Allerject ^® in the U.S. and Canada. The negative impact of this recall on sales was -€122 million, which corresponded mainly to the reversal of sales of the product since the beginning of 2015. Sanofi no longer commercializes this product and no sales were recorded in 2016. 

Consumer Healthcare

(a) Excluding Venezuela: +1.4%;

In the fourth quarter, Consumer Healthcare (CHC) sales increased 2.7% to €834 million driven by the performance in Europe, reflecting an early cough and cold season, partially offset by lower sales in Russia. Excluding the divestiture of several small products, sales of CHC were up 3.2% in the fourth quarter.

Fourth-quarter CHC sales in the U.S. increased 4.6% to €209 million despite increased competitive environment in the allergy category. In Emerging Markets, sales decreased 3.2% to €326 million reflecting lower sales in Russia due to the challenging local economic situation. In the quarter, sales in Europe were up 9.5% to €229 million due an early start of cough and cold season, mainly in France, despite the divesture of small products. Adjusting for these divestitures, CHC sales in Europe were up 11.1% in the fourth quarter. Full-year CHC sales reached €3,330 million, down 1.6% (up 2.7% excluding Venezuela and the divestiture of several small products).

Sanofi and Boehringer Ingelheim recently announced that the exchange of Sanofi's animal health business (Merial) and Boehringer Ingelheim's consumer healthcare (CHC) business was successfully closed in most markets on January 1st 2017. The closing of the disposal of Merial in Mexico and the swap of Merial and CHC in India have been delayed pending receipt of certain regulatory approvals. The transactions in both countries are expected to close early 2017.

Generics

In the fourth quarter, Generics sales increased 0.2% to €468 million driven by Emerging Markets (up 5.1% to €209 million) and Japan, which more than offset for the U.S. (down 6.8% to €43 million) and Europe (down 6.6% to €192 million). In 2016, Generics sales were up 0.7% to €1,854 million (up 2.5% excluding Venezuela).

As announced in our 2020 strategic roadmap, Sanofi has carefully reviewed all options for our Generics business in Europe and recently made the definitive decision to initiate a carve-out process expected to be completed by the end of 2018. Importantly, Sanofi confirms its commitment to Generics in other parts of the world with a greater focus on the Emerging Markets.

Vaccines

*Comparability based on the new presentation of VaxServe sales (see below)  (a) Excluding Venezuela: +9.0%;

Fourth quarter consolidated Vaccines sales were up 3.7% to €1,352 million mainly driven by the Polio/Pertussis/Hib (PPH) franchise both in the U.S. (total US sales up 7.8% to €704 million) and in Emerging Markets (total Emerging Markets sales up 7.3% to €521 million) despite early flu shipments in the U.S. in the third quarter. In Europe, vaccines sales were down 46.3% to €44 million mainly reflecting both (i) supply issues with Repevax ^® and (ii) sales from Sanofi to Sanofi Pasteur MSD deferred to 2017 in connection with the buy-back of inventory as part of the termination of Sanofi Pasteur MSD joint-venture. In 2016, sales of Sanofi Pasteur increased 8.8% to €4,577 million mainly driven by the PPH franchise, the benefits from our flu differentiation strategy and, to a lesser extent, the dengue launch.

In the fourth quarter, Polio/Pertussis/Hib vaccines sales increased 16.5% to €544 million reflecting supply improvements of Pentacel ^® in the U.S. (€119 million versus €53 million in the fourth quarter of 2015). Customer allocations for Pentacel ^® were removed in December 2016 and both private and public channels have now full access to Pentacel to meet their needs. In Emerging Markets, PPH sales increased 5.1% to €304 million driven by the growth of Hexaxim ^® , partially offset by the impact of local market disruption in China. Full-year PPH sales were up 12.7% to €1,495 million.

Fourth-quarter Influenza vaccines sales were down 5.3% to €416 million due to early shipments in the U.S. in the third quarter. Sales of Influenza vaccines were down 14.0% to €280 million in the U.S. in the fourth quarter. In 2016, Influenza vaccines sales increased 16.6% to €1,521 million, reflecting Sanofi Pasteur's strategy to offer a portfolio of differentiated influenza vaccines. 2016 was a new record year for the Influenza franchise of Sanofi Pasteur.

Adult Booster vaccines sales decreased 15.3% to €129 million in the fourth quarter, as a result of lower sales in Europe due to a Repevax ^® supply disruption. In the U.S. adult Booster vaccines sales were down 2.0% to €100 million. Full-year sales of Adult Booster vaccines decreased 15.5% to €417 million mainly driven by supply issues with Repevax ^® and increased competitive pressure towards Adacel ^® in the US.

Dengvaxia ^® , the world's first dengue vaccine, is now approved in 14 countries (Bolivia, Brazil, Cambodia, Costa Rica, El Salvador, Guatemala, Indonesia, Mexico, Paraguay, Peru, Thailand, Singapore Venezuela and the Philippines). As expected, sales of Dengvaxia ^® were limited (€5 million) in the fourth quarter as no new immunization programs were implemented. These sales were generated in the private market and by the public vaccination program launched in Paraná State in Brazil in the third quarter. In 2016, Dengvaxia ^® sales were €55 million.

Fourth-quarter Menactra ^® sales were up 1.0% to €107 million, €93 million of which was generated in the U.S (up 7.1%) reflecting the market leadership of Menactra ^® . In 2016, sales of Menactra ^® increased 4.8% to €586 million.

Fourth-quarter and full-year 2016 Travel and other endemic vaccines sales were €107 million (up 4.0%) and €368 million (down 0.8%), respectively.

In the fourth quarter, Sanofi Pasteur MSD , the joint venture with Merck & Co. in Europe, sales (not consolidated) increased 25.5% (on a reported basis) to €301 million. Excluding the 2016 year-end inventories repurchase to both parent companies, sales were flat, the growth of Hexyon ^® (pediatric hexavalent vaccine) and travel vaccines sales being largely offset by lower Influenza and boosters vaccines sales. In 2016, sales of Sanofi Pasteur MSD were up 14.1% (on a reported basis) to €940 million (including the disposal of 2016 year-end inventories to both parent companies).

As previously announced, on January 2, 2017, Sanofi Pasteur and MSD separated their vaccine joint venture in Europe in order to pursue their own vaccine strategies and integrate their respective European vaccines businesses into their own operations.

Company sales by geographic region

(a) World excluding U.S., Canada, Western & Eastern Europe (except Eurasia), Japan, South Korea, Australia, New Zealand and Puerto Rico (b) India, Pakistan, Bangladesh, Sri Lanka (c) Russia, Ukraine, Georgia, Belarus, Armenia and Turkey (d) Western Europe + Eastern Europe except Eurasia (e) Japan, South Korea, Canada, Australia, New Zealand, Puerto Rico

Fourth-quarter sales in the U.S. increased 11.3% to €3,321 million driven mainly by double digit growth of the multiple sclerosis franchise (up 37.4%) and Established products (up 22.4%), reflecting the low basis for comparison from the impact (-€122 million) of the recall of Auvi-Q ^® in the fourth quarter of 2015. Growth in the fourth quarter also benefited from the performance of the Rare disease (up 7.7%), Oncology (up 5.0%), CHC (up 4.6%) and Vaccines (up 7.8%) franchises. The U.S. sales performance included growth of diabetes franchise (up 5.5%), aided by a low basis for comparison in the fourth quarter 2015. In 2016, sales in the U.S. increased 5.1% to €12,391 million.

Sales in Emerging Markets increased 3.5% to €2,602 million in the fourth quarter driven by Rare Disease (up 23.5%), Diabetes (up 4.1%), Generics (up 5.1%) and Vaccines (up 7.3%). In the Asia region, fourth-quarter sales decreased 2.8% to €782 million reflecting lower sales in China (down 10.5% to €496 million), primarily impacted by local vaccines market disruption and inventory fluctuation. In Latin America, fourth-quarter sales increased 4.2% to €710 million driven by sales in Argentina and Brazil. Fourth-quarter sales in Brazil increased 5.6% to €244 million supported by performance of Vaccines and Established products. Fourth-quarter sales in the Eurasia region increased 8.4% to €329 million supported by strong growth in Turkey and Ukraine. Over the quarter, sales in Russia returned to growth (up 3.0% to €178 million). In Africa, the Middle-East and South Asia, sales were up 11.4% to €752 million sustained by double digit growth in Middle-East, Africa and India. In 2016, sales in Emerging Markets increased 2.4% to €9,593 million. Excluding Venezuela, 2016 sales in Emerging Markets grew 7.0%. 2016 sales in China, Brazil and Russia were €2,039 million (up 0.5%), €983 million (up 1.7%), €499 million (down 7.1%), respectively.

Fourth-quarter sales in Europe were down 1.7% to €2,134 million. The performance of multiple sclerosis (up 34.8%), Rare disease (up 4.5%) and CHC (up 9.5%) were offset by lower sales in Diabetes (down 5.6%), Established Rx Products (down 3.3%) and Vaccines (down 46.3%). In 2016, sales in Europe increased 0.6% to €8,679 million.

Sales in Japan decreased 22.2% to €428 million in the fourth quarter, impacted by generic Plavix ^® competition (down 49.3% to €82 million). In Japan, 2016 sales decreased 24.8% to €1,688 million.

R&D update

Regulatory update

Regulatory updates since the publication of the third quarter results on October 28, 2016 include the following: 

• In January 2017, Kevzara (TM) (sarilumab) was approved in Canada for the treatment of moderate to severe rheumatoid arthritis in adults. On October 28, 2016, the U.S. Food and Drug Administration (FDA) issued a Complete Response Letter (CRL) regarding the Biologics License Applications (BLA) for sarilumab for the treatment of adult patients with moderately to severely active rheumatoid arthritis. The CRL refers to certain deficiencies identified during a routine good manufacturing practice inspection of the Sanofi Le Trait facility where sarilumab is filled and finished, one of the last steps in the manufacturing process. Satisfactory resolution of these deficiencies is required before the BLA can be approved. Based on review of Sanofi's responses to the FDA 483 letters as well as proposed corrective actions, the FDA has classified the Le Trait 'fill and finish' facility as "acceptable". Sanofi plans the re-submission of sarilumab U.S. BLA in the first quarter of 2017 subject to successful FDA pre-approval inspection of Le Trait.  
• In December 2016, the European Medicines Agency accepted for review the Marketing Authorization Application for Dupixent ^® (dupilumab) for the treatment of adults with moderate-to-severe atopic dermatitis (AD) who are candidates for systemic therapy.  
• In November 2016, the FDA approved once-daily Soliqua (TM) 100/33 (insulin glargine 100 Units/mL & lixisenatide 33 mcg/mL injection) for the treatment of adults with type 2 diabetes inadequately controlled on basal insulin (less than 60 Units daily) or lixisenatide. In January 2017, the European Commission also approved Suliqua (TM) in combination with metformin for the treatment of adults with type 2 diabetes to improve glycemic control when this has not been provided by metformin alone or metformin combined with another oral glucose lowering medicinal product or with basal insulin. 

At the beginning of February 2017, the R&D pipeline contained 44 pharmaceutical new molecular entities (excluding Life Cycle Management) and vaccine candidates in clinical development of which 13 are in Phase 3 or have been submitted to the regulatory authorities for approval.

Portfolio update

Phase 3:

• Sotagliflozin , an oral SGLT-1&2 inhibitor, entered into Phase 3 in type 2 diabetes.

• Shan6, a pediatric hexavalent vaccine from Shantha, entered Phase 2.  
• A vaccine entered Phase 2 against HIV infection for at risk population.

Phase 1:  

• SAR439794 , a TLR4 agonist immunomodulator, entered Phase 1 for the treatment of peanut allergy.  
• An inactivated Zika vaccine entered Phase 1.  
• Respiratory Syncytial Virus vaccine for infants entered Phase 1.

Collaboration

On December 28th, 2016, Hanmi and Sanofi entered into an amendment to their initial license agreement executed for the development of a portfolio of long-acting diabetes treatments. Sanofi returned to Hanmi the rights related to the weekly long-acting insulin to primarily focus on development of the weekly GLP-1 (efpeglenatide). Hanmi will take the development lead on the weekly insulin and will assume responsibility for the development of the long-acting weekly efpeglenatide/insulin drug combination for a certain period of time, after which Sanofi will re-assume responsibility for development.

The gross margin ratio improved by 0.8 percentage points to 70.2% versus the fourth quarter of 2015, reflecting mainly the positive impact of Aubagio ^® and rare disease franchise, the low basis for comparison in the fourth quarter of 2015 from the recall of Auvi-Q ^® and Medicaid delayed bills related to Lantus ^® as well as industrial productivity improvements. In 2016, the gross margin ratio improved by 0.7 percentage points to 71.0% versus 2015, driven by the strong performance of Sanofi Genzyme.
