Q2 2013: Last Quarter with Significant Negative Impact from the Patent Cliff

	Q2 2013		Change (reported)		Change (CER)		H1 2013		Change (reported)		Change (CER)
Net sales	€	8,003m	-9.8	%	-6.3	%	€	16,062m	-7.6	%	-4.6	%
Business net income(1)	€	1,475m	-23.4	%	-18.4	%	€	3,088m	-29.0	%	-24.2	%
Business EPS(1)	€	1.11	-24.0	%	-18.5	%	€	2.33	-29.4	%	-24.5	%

In order to facilitate an understanding of our operational performance, we comment on our business net income statement. Business net income(1) is a non-GAAP financial measure. The consolidated income statement for H1 2013 is provided in Appendix 4 and a reconciliation of business net income to consolidated net income in Appendix 3. Consolidated net income for H1 2013 was €1,448 million, compared to €2,962 million(2) for H1 2012. Consolidated EPS for H1 2013 was €1.09 versus €2.25(2) for H1 2012.

Commenting on the Group’s performance in Q2 2013, Sanofi Chief Executive Officer, Christopher A. Viehbacher said, “The second quarter was a difficult quarter. As expected, this was the last quarter with a tough comparison to the prior year due to the residual impact of the patent cliff. Sales were also affected by our business in Brazil(3) and commercial underperformance in certain business areas. However, sales growth of 7.7%(4) of our growth platforms(5) in the first half of 2013 continues to demonstrate the value of Sanofi’s integrated business model. In addition, we keep on making strong progress in delivering a growing portfolio of high potential R&D assets, as highlighted by the multiple clinical and regulatory milestones reached in the second quarter of 2013. We continue to expect to return to growth in the second half of 2013.”

Q2 2013 Performance

·Total sales(6) were €8,003 million, down 6.3% principally impacted by sales lost due to generic competition (€481 million).

·Sales in Emerging Markets(7) totalled €2,669 million, a decrease of 2.3% (+5.3% excluding Brazil generics); double-digit sales growth was achieved for Diabetes, Vaccines, Genzyme and Animal Health.

·Diabetes delivered growth of 16.2% to €1,621 million as Lantus® sales reached €1,409 million, an increase of 17.7%.

·Consumer Healthcare sales were €729 million, an increase of 1.8%.

·Vaccines sales reached €760 million (+0.4%) and compared to strong Q2 2012 sales which benefited from a later timing of flu vaccines supply in the Southern Hemisphere.

·Animal Health sales were down 5.7% to €529 million impacted by unfavorable weather conditions and increased competition to Frontline®.

·Genzyme recorded another strong quarter with sales growth of 25.6% to €525 million, reflecting strong performance of the rare disease franchise and the progression of Aubagio®.

·Growth platforms(5) sales were €5,718 million, an increase of 2.5% (+6.2% excluding Brazil generics) and accounted for 71.4% of total sales.

·Q2 2013 business EPS(1) was €1.11, down 18.5% impacted in particular by the Plavix® and Avapro® losses of exclusivity in the U.S. (€0.18) and Brazil generics (€0.17)(8).

R&D Update

·Since publication of Q1 2013 results, several positive Phase III trials results have been announced including two Phase III trials for the investigational new insulin U300, and JAKARTA, which examined fedratinib, a selective JAK2 inhibitor, in myelofibrosis. In addition, the C. diff toxoid vaccine is now moving to Phase III.

·Several major regulatory milestones were also achieved including positive recommendations from the CHMP both on Lemtrada™ and on a new active substance designation for Aubagio® which is expected to lead to 10-year exclusivity and the FDA approval of the Fluzone® Quadrivalent vaccine.

2013 Adjusted Guidance

·Given the impact of Brazil and the year-to-date performance, 2013 business EPS is expected to be 7% to 10% lower than 2012 at CER(9), barring major unforeseen adverse events.

2013 second-quarter and first-half sales

Unless otherwise indicated, all sales growth figures in this press release are stated at constant exchange rates(1).

In the second quarter of 2013, Sanofi sales were €8,003 million, a decrease of 9.8% on a reported basis. Exchange rate movements had a negative effect of 3.5 percentage points primarily reflecting the depreciation of the Japanese Yen, U.S. Dollar, Venezuelan Bolivar, and the South African Rand against the Euro.

First-half sales reached €16,062 million, a decrease of 7.6% on a reported basis. Exchange rate movements had an unfavorable effect of 3.0 percentage points mainly driven by the depreciation of the Japanese Yen, U.S. Dollar, Venezuelan Bolivar, Brazilian Real, and the South African Rand against the Euro.

Growth Platforms

Second-quarter sales of the Group’s growth platforms totaled €5,718 million, an increase of 2.5%, driven by the performance of Diabetes (up 16.2%), Genzyme (up 25.6%) and “Other Innovative Products” (up 14.5%). The Group’s growth platforms accounted for 71.4% of total consolidated sales in the second quarter, up from 71.0% in the second quarter of 2012. Excluding Brazil generics, growth platforms grew 6.2% and Emerging Markets grew 5.3%.

During the second quarter, Sanofi determined that generic inventory levels in trade channels in Brazil were significantly and inappropriately in excess of volumes needed to satisfy sell out demand. Accordingly, an adjustment has been recorded in the current quarter to reflect product returns, customer discounts and rebates. The net effect of this adjustment was to lower net sales by €122 million. An additional provision of €79 million has also been recorded for the write-off of inventory and other related costs.

First-half sales of growth platforms reached €11,441 million, an increase of 5.4%, and accounted for 71.2% of total consolidated sales compared with 70.8% in the first half of 2012. Excluding Brazil generics, growth platforms were up 7.7%.

Pharmaceuticals

In the second quarter, sales for the Pharmaceuticals business were €6,714 million, a decrease of 7.1%, which reflected generic competition, EU austerity measures and an adjustment of €122 million related to Brazil. Sales lost due to generic competition on main legacy products in the U.S. and EU were €481 million, primarily due to declining sales of Eloxatin®, Lovenox® and the active ingredient of Plavix® in the U.S. and Aprovel® in the EU.

First-half sales for the Pharmaceuticals business reached €13,522 million, a decrease of 5.7%. First-half sales lost due to generic competition on main legacy products in the U.S. and EU were €1,036 million.

First-half consolidated sales of Sanofi Pasteur were €1,457 million, an increase of 7.2%. Second-quarter consolidated sales of Sanofi Pasteur reached €760 million, up 0.4% reflecting strong performance of Pentaxim® in Emerging Markets partially offset by the unfavorable impact of phasing for seasonal influenza vaccine in the Southern Hemisphere in the second quarter of 2012 and supply limitations for Pentacel® in the U.S.

Sales of Polio/Pertussis/Hib vaccines increased 12.5% to €293 million, driven by the performance of Pentaxim® which largely offset supply limitations for Pentacel® in the U.S. Total sales of Pentaxim® grew 48.3% to €87 million driven by good performances in Mexico and China. Sales of Imovax® in Japan were €5 million reflecting the end of the catch-up cohort following the launch in September 2012. In the U.S., as previously announced, Sanofi Pasteur foresees progressive supply recovery of Pentacel® to begin in the third quarter of 2013. First-half sales of Polio/Pertussis/Hib vaccines grew 14.1% to €563 million.

Second-quarter sales of influenza vaccines were €53 million, a decrease of 32.5% due to the high level of sales in the second quarter of 2012 which benefited from favorable phasing for seasonal influenza vaccines in the Southern Hemisphere. First-half sales of influenza vaccines were €172 million, up 3.0%. In June, the FDA approved the supplemental biologics license application for licensure of Sanofi Pasteur four-strain influenza vaccine, Fluzone® Quadrivalent vaccine.

Second-quarter sales of Menactra® reached €100 million (down 6.3%), reflecting phasing of public orders in the U.S. (sales were €77 million, a decrease of 18.4%) partially offset by good performance in the Middle East and to a lesser extent Latin America. First-half sales of Menactra® were €167 million, an increase of 2.4%.

Adult booster vaccines sales were €124 million (down 13.7%) and €209 million (down 9.0%) in the second quarter and the first half, respectively due to lower sales of Adacel®.

Sales of travel and other endemic vaccines reached €98 million (up 1.0%) in the second quarter and €172 million (down 0.6%) in the first half, respectively, and were impacted by the temporary production suspension of Theracys®/Immucyst® and BCG vaccines.

Second-quarter sales of other vaccines were €69 million, an increase of 30.9%, reflecting growth of VaxServe(13).

In Brazil, sales were €154 million reflecting a net sales adjustment of €122m, as well as lower oncology and flu vaccines sales.

Genfar S.A., a leading pharmaceuticals manufacturer headquartered in Bogota, Colombia, was consolidated in the second quarter. With this acquisition, Sanofi has become a market leader in Colombia and has further expanded its portfolio of affordable pharmaceuticals in Latin America.

Second-quarter sales in the U.S. were €2,463 million, down 10.0% reflecting primarily the loss of exclusivity of Eloxatin® at the beginning of August 2012 (down 97.4%) which was partially offset by the strong performance of Diabetes (up 21.0%) and Genzyme (up 38.5%). First-half sales in the U.S. totaled €4,797 million, down 9.9%.

Sales in Western Europe were €1,958 million in the second quarter, a decrease of 7.9%, impacted by generic competition to Aprovel® as well as austerity measures. First-half sales in Western Europe totaled €3,958 million, down 9.0 %.

Sales in Japan totaled €594 million, a decrease of 7.2%, primarily reflecting the impact of generic competition to Allegra®, Myslee® and Amaryl® partially offset by the performance of vaccines and Plavix®. First-half sales in Japan were €1,284 million, up 1.0%.

R&D update

Consult Appendix 7 for full overview of Sanofi’s R&D pipeline

Since the publication of the first-quarter 2013 results on May 2, 2013, the regulatory newsflow has been favorable:

·In June The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) issued a positive opinion for approval of Lemtrada™ (alemtuzumab) for the treatment of adult patients with relapsing remitting multiple sclerosis (RRMS) with active disease defined by clinical or imaging features. In addition, the CHMP issued a positive opinion on the new active substance designation for Aubagio® (teriflunomide). In March, the CHMP issued a positive opinion recommending the approval of Aubagio® for the treatment of adult patients with relapsing remitting MS.

·In June, the Japan’s Ministry of Health, Labour and Welfare approved the manufacturing and distribution of Lyxumia® for the treatment of type 2 diabetes. Lyxumia®, the first once-daily prandial GLP-1 receptor agonist (RA), is also the first GLP-1 RA approved in Japan for use in combination with basal insulin. Lyxumia® is indicated for patients with type 2 diabetes when the following do not provide adequate glycemic control: diet and exercise and sulfonylureas or diet and exercise and soluble prolonged-acting or intermediate-acting insulin.

·In June, the U.S. Food and Drug Administration approved the supplemental biologics license application for licensure of Sanofi Pasteur’s four-strain influenza vaccine, Fluzone® Quadrivalent vaccine. Fluzone® Quadrivalent vaccine is the newest addition to the Fluzone® family of influenza vaccines. Like Sanofi Pasteur’s Fluzone® vaccine, Fluzone® Quadrivalent vaccine is licensed for use in children six months of age and older, adolescents, and adults. The 2013 influenza season will be the first in which quadrivalent influenza vaccines will be available in the U.S.

·In June, the CHMP of the European Medicines Agency issued a positive opinion for inclusion in the Lantus® (insulin glargine) product label of safety and efficacy data from the ORIGIN (Outcome Reduction with Initial Glargine INtervention) cardiovascular (CV) outcomes trial.

·In June, the European market authorization was granted for MACI® (matrix assisted autologous chondrocyte implantation).

At the beginning of August 2013, the R&D pipeline contained 60 projects (excluding Life Cycle Management) and vaccine candidates in clinical development of which 14 are in Phase III or have been submitted to the health authorities for approval.

Portfolio update

·The C. diff toxoid vaccine developed by Sanofi Pasteur for the prevention of primary symptomatic Clostridium difficile infections (CDI), a leading cause of life-threatening, healthcare associated infections worldwide, will move into Phase III in August 2013. The trial will include up to 15,000 volunteers across 200 trial sites in 17 countries and is estimated to take four years to complete, based on the incidence of CDI and necessary follow-up required with patients after vaccination.

·A trial evaluating alirocumab (a subcutaneous administered, fully human monoclonal antibody targeting PCSK9, collaboration with Regeneron) dosed every four weeks (ODYSSEY CHOICE) is expected to commence by the end of 2013.

·In June, the first Phase III study results (EDITION I) for the investigational new insulin U300 were presented at the Scientific Sessions of the American Diabetes Association. The EDITION I study evaluated the efficacy and safety of U300, vs. Lantus® in people with type 2 diabetes using basal plus mealtime insulin. In this study, U300 showed equivalent blood sugar control with fewer night-time low blood sugar events compared to Lantus®. Sanofi also announced topline results of a second Phase III study (EDITION II) which evaluated efficacy and safety of U300 in a type 2 diabetes population treated with basal insulin plus oral antidiabetic therapy. The topline results of EDITION II also demonstrated similar blood sugar reduction while fewer patients experienced night-time low blood sugar events compared with Lantus®. EDITION I and EDITION II are part of the EDITION Phase III clinical program evaluating the efficacy and safety of the investigational new insulin U300 in people with diabetes.

·In May, Sanofi and Regeneron announced that the COMPARE and ASCERTAIN trials of sarilumab, the first fully human monoclonal antibody directed against the IL-6 receptor, which is delivered by subcutaneous injection every other week, enrolled their first patients. These two Phase III studies are part of the broad SARIL-RA clinical development program which focuses on adult populations with moderate to-severe rheumatoid arthritis (RA) who are inadequate responders to either methotrexate or TNF-alpha inhibitor therapy. Furthermore, a Phase II trial (SARIL-NIU-SATURN) of sarilumab in posterior non-infectious uveitis is being initiated.

·In May, it was announced that the pivotal study, JAKARTA, examining fedratinib, a selective JAK2 inhibitor (SAR302503) for myelofibrosis, met its primary endpoint in both dose groups. The primary endpoint assessed the proportion of patients achieving >35% reduction of spleen volume. Consistent with data reported in previous trials, the most common adverse events were anemia, diarrhea, nausea and vomiting. Full results will be presented at an upcoming medical congress.

·In May, the New England Journal of Medicine published online the positive Phase IIa study results of dupilumab (SAR231893, partnership with Regeneron) in patients with moderate-to-severe allergic asthma. Dupilumab is an investigational monoclonal antibody targeting the alpha subunit of the interleukin 4 receptor (IL-4R alpha), which modulates signaling of both IL-4 and IL-13, drivers of Th2 (Type 2 helper T cell) immune response. The study results were presented at a late-breaking clinical trials session at the American Thoracic Society 2013 International Conference. Following the positive proof of concept results in asthma and atopic dermatitis, the Phase IIb program evaluating dupilumab in asthma and the atopic dermatitis began mid-year as planned.

·One compound from Genzyme (GZ438027, collaboration with Alnylam) entered Phase II for familial amyloid polyneuropathy (FAP).

·In June, Sanofi announced its decision to terminate the internal development program for iniparib following the announcement that the randomized Phase III trial of iniparib in squamous non-small cell lung cancer did not meet its primary endpoint and also that the topline results of a Phase II study of iniparib in platinum-resistant ovarian cancer did not support further development of iniparib. In June, Sanofi also announced its decision to discontinue the investigational program for otamixaban following the topline results of the TAO study which did not meet its primary endpoint of superiority over current therapy in non-ST elevation acute coronary syndrome patients planned for early invasive strategy.

·The Phase II program in breast cancer of the current formulation SAR245408 (XL 147), the orally available inhibitor of phosphoinositide-3-kinase (PI3K) licensed from Exelixis, in combination with letrozole or trastuzumab (studies ARD11437 and ARD11439, respectively) has been discontinued, and a trial in combination with SAR256212 (MM121, ErbB3 inhibitor in partnership with Merrimack) is being completed. A Phase I program to evaluate a new formulation is ongoing.

·One project in Phase I (GZ402674 in solid tumors) has been discontinued.

Second-quarter and first-half 2013 financial results

Business Net Income(1)

Sanofi generated second-quarter net sales of €8,003 million, a decrease of 9.8% on a reported basis (-6.3% at constant exchange rates). First-half sales were €16,062 million, a decrease of 7.6% on a reported basis (-4.6% at constant exchange rates).

Other revenues decreased 66.4% to €83 million in the second quarter, impacted by the loss of exclusivity of Plavix® in the U.S. on May 17, 2012 and the end of royalties on Enbrel® sales in the U.S. In the first half, other revenues were €181 million down 73.1%.

Second-quarter Gross profit was €5,414 million, down 15.3% (down 11.7% at constant exchange rates), impacted by lower other revenues and decreased sales from key genericized products with relatively low cost of sales. The ratio of cost of sales to net sales reached 33.4% compared to 30.7% in the second quarter of 2012. Excluding Brazil generics, this ratio was 32.1% reflecting generic competition, the evolution of the Vaccines sales and Animal Health sales mix and unfavorable currency impact partially offset by positive effect from Lantus® and Genzyme. First-half gross profit reached €11,035 million, down 13.3% (or 10.1% at constant exchange rates). In the first half of 2013, the ratio of cost of sales to net sales was 32.4%, or 31.6% excluding Brazil generics.

Research and Development expenses were €1,186 million in the second quarter, a decrease of 4.0% (down 2.4% at constant exchange rates) reflecting investment in the late-stage portfolio offset by lower internal research expenses. First-half R&D expenses reached €2,341 million, down 2.7% (or down 1.5% at constant exchange rates). In the first half of 2013, the ratio of R&D to net sales was 14.6%, versus 13.8% in the first half of 2012.

Second-quarter selling and general expenses totaled €2,309 million, up 1.1%. At constant exchange rates, SG&A increased 4.3% reflecting the commercial investment of Genzyme in multiple sclerosis and increased marketing efforts in the U.S. Diabetes business. General expenses remained broadly stable (up 0.5% at constant exchange rates) reflecting tight cost control. First-half SG&A expenses reached €4,438 million, up 0.8% (or 3.5% at constant exchange rates). In the first half of 2013, the ratio of selling and general expenses to net sales was 27.6%, versus 25.3% in the first half of 2012.

Other current operating income net of expenses was an income of €140 million in the second quarter versus a charge of €141 million in the second quarter of 2012 which included an additional reserve of €118 million linked to ramipril patent litigation in Canada. The second quarter 2013 included a capital gain linked to the sales of the U.S. rights of tail products to Covis Pharma, a competition fine related to Plavix® in France and provisions related to Brazil Generics. In the first half of 2013, other current operating income net of expenses was an income of €170 million compared to an income of €16 million in the same period of 2012.

The share of profits from associates was €3 million in the second quarter versus €122 million in the second quarter of 2012 reflecting the loss of exclusivity of Plavix® in the U.S. First-half 2013 share of profits from associates were €21 million versus €419 million in the first half of 2012.

Non-controlling interests decreased 10.0% to -€45 million in the second quarter, mainly reflecting lower profit generated by Plavix® and Avapro® mainly in Europe attributable to Bristol-Myers Squibb. In the first half of 2013, non-controlling interests were -€86 million, down 17.3%.

Second-quarter business operating income was €2,017 million, down 28.0% (down 23.6% at constant exchange rates) and included a negative impact of €290 million(14) from Brazil generics. The ratio of business operating income to net sales was 25.2%. Excluding Brazil generics, this ratio was 28.4%. First-half business operating income was €4,361 million, a decrease of 30.2% (down 25.7% at constant exchange rates). The ratio of business operating income to net sales was 27.2%, compared to 35.9% in the first half of 2012.

Net financial expenses reached €137 million, compared to €156 million in the second quarter of 2012. First-half net financial expenses were €277 million versus €325 million in the first half of 2012.

The Group has revised its 2013 effective tax rate forecast and now anticipates a rate of around 24.0%. The first-half effective tax rate has been adjusted to this rate and consequently the effective tax rate for the second quarter was 21.1%. The main reasons for the reduction in the rate are the constant evolution of our geographical mix of earnings as well as recent and ongoing procedures with the tax authorities in a number of countries which have or are expected to have a positive impact in 2013.

Appendix 8: Definitions of non-GAAP financial indicators

Net sales at constant exchange rates (CER)

When we refer to changes in our net sales “at constant exchange rates” (CER), this means that we exclude the effect of changes in exchange rates.

We eliminate the effect of exchange rates by recalculating net sales for the relevant period at the exchange rates used for the previous period.

Reconciliation of reported net sales to net sales at constant exchange rates for the second quarter and the first half of 2013

€ million	Q2 2013	H1 2013
Net sales	8,003	16,062
Effect of exchange rates	305	517
Net sales at constant exchange rates	8,308	16,579

Net sales on a constant structure basis

We eliminate the effect of changes in structure by restating prior-period net sales as follows:

·by including sales from the acquired entity or product rights for a portion of the prior period equal to the portion of the current period during which we owned them, based on sales information we receive from the party from whom we make the acquisition;

·similarly, by excluding sales in the relevant portion of the prior period when we have sold an entity or rights to a product;

·for a change in consolidation method, by recalculating the prior period on the basis of the method used for the current period.

Business net income

Sanofi publishes a key non-GAAP indicator. This indicator “Business net income”, replaced “adjusted net income excluding selected items”.

Business net income is defined as net income attributable to equity holders of Sanofi excluding:

·amortization of intangible assets,

·impairment of intangible assets,

·fair value remeasurement of contingent consideration liabilities related to business combinations,

·other impacts associated with acquisitions (including impacts of acquisitions on associates),

·restructuring costs(1),

·other gains and losses (including gains and losses on disposals of non-current assets(1)),

·costs or provisions associated with litigation(1),

·tax effects related to the items listed above as well as effects of major tax disputes.

·Tax (3%) on dividends paid to Sanofi shareholders.

(1)Reported in the line items Restructuring costs and Gains and losses on disposals, and litigation, which are defined in Note B.20. to our consolidated financial statements.
