Stallergenes Greer Reports Strong First Half 2017 Results and Narrows 2017 Financial Guidance

Regulatory News:

Stallergenes Greer plc (Paris:STAGR), a biopharmaceutical company specialising in treatments for respiratory allergies, today announces its half-year results for the six-month period ended 30 June 2017.

Fereydoun Firouz, Chairman and Chief Executive Officer of Stallergenes Greer, commented:

"During the first half of 2017, Stallergenes Greer delivered strong revenue growth with diligent cost control. As a result of the actions we have taken, we have narrowed our loss and significantly improved our cash flow. With positive EBITDA at the end of first half, we are ahead of schedule. These financial results make us confident enough to narrow our revenue guidance¹ to the high end of the range.

"This performance reflects the Company’s progress and transformation accomplished since the temporary suspension of production in late 2015 that affected one of our sites for several months. With steady market share gains across our portfolio month after month, we have been relentlessly focused on customer satisfaction and we are positioned to regain our global market leadership. We have upgraded our manufacturing processes and we can now see the impact of our new ERP system in our financial results. In most countries, we outperform the industry standard by delivering products in six days compared to ten to fifteen days standard practice.

"As part of our commitment to bring innovative solutions to patients suffering from allergies, we have also continued to advance science in allergy immunotherapy (AIT). At the EAACI² congress in June 2017, we presented real-world evidence data that showed the long-term benefit of ORALAIR in controlling allergic rhinitis and potentially preventing asthma. Recently, we announced the completion of the enrolment for STG320, the largest phase III clinical trial for house dust mite induced allergy.

"We are at an exciting turning point for Stallergenes Greer and we are confident in the strength of our organisation to deliver on our operational plan and to keep up the momentum.”

First half 2017 financial highlights

The Group has continued to deliver consistent progress enabled by the RESTART (Restart Stallergenes Greer After Revalidation Task) program initiated early 2016 and a focus on excellence across the organisation. For the first half of 2017, total revenues increased 66% to €129.6 million reflecting the significant recovery of the business since operations gradually resumed following several months suspension of production in Antony, France, in late 2015.

Overall, the Group delivered 70% of the pro forma sales achieved in the first half of 2015, a peak year, paving the way for the Group to regain its leading position in Europe and International allergy immunotherapy markets.

Revenue growth has been fuelled by market share regained across the portfolio. In France, ORALAIR held a 38% market share, a 15-point increase compared to June 2016. In Germany, ORALAIR held a 39% market share for June 2017, a 6-point increase compared to June 2016.

The gross margin of €83.4 million represented 64% of net sales, compared to 45% in the first half of 2016 as the increase in net sales more than offset the increase in cost of goods sold.

EBITDA for the first half of 2017 was €6.3 million, a significant turnaround compared to the negative EBITDA of €45.1 million in the first half of 2016, reflecting improved sales and the positive impact of effective operating cost management. Accordingly, the current operating loss of €3.5 million has also improved compared to the operating loss of €58.5 million for the first half of 2016.

Selling, general and administration expenses were €65.1 million, down €6.2 million versus €71.3 million at 30 June 2016.

At 30 June 2017, the Group had "cash and cash equivalents" of €47.6 million. In addition, the Group has limited external debt with an outstanding debt balance of €16.0 million. This has resulted in a net cash position of €31.6 million.

Region highlights

Southern Europe first half 2017 net sales were €53.7 million, up €35.9 million or 202% over the prior-year period. The progress is mainly due to the positive impact of the RESTART program and the regain of the market share lost during the temporary production and distribution suspension at the site in Antony in late 2015.

North & Central Europe net sales were €18.5 million, up €7.8 million or 73% over the prior-year period.

International markets net sales were €11.8 million, up €7.1 million or 151% over the prior-year period with notable performance in Australia that successfully launched ACTAIR^®, Stallergenes Greer’s tablet for house dust mite induced allergy.

In the US, first half 2017 net sales grew 2% to €45.6 million over the prior-year period. The slower growth is in part due to competitor pricing and discount strategy in the human bulk allergen business and in the veterinary product category. Despite this, the Group has maintained its leading market share in the human bulk allergen business while ORALAIR has continued to gain incremental market share.

Product highlights

In the first half of 2017, the Group fulfilled 90% of the demand for all sublingual allergens, as well as the top three subcutaneous allergens (house dust mite, grass, birch) most needed by patients and physicians in Europe and International markets. Product lead time³ improved from three weeks to six days setting up new industry standards in delivering the right product to the right patient at the right time.

Sublingual sales increased by €49.6 million or 182% compared to €27.3 million from 30 June 2016. Sales reached 63% of the sales achieved in the first half of 2015, prior to the temporary suspension. The sublingual product category includes STALORAL sublingual liquid solution as well as ORALAIR and ACTAIR tablets.

Subcutaneous sales were €36.9 million for the period, up 8% or €2.7 million from €34.2 million at 30 June 2016. Sales reached 85% of the sales achieved in the first half of 2015, prior to the temporary suspension. The subcutaneous product category includes ALUSTAL^® and PHOSTAL^®.

Other sales, which include Diagnostics and Ancillary products, were €10.8 million, down €0.3 million or 3% from €11.1 million.

Veterinary sales in the US were €5.0 million for the period, down €0.4 million or 7% from €5.4 million of sales at 30 June 2016.

Innovation

In March, Shionogi & Co., Ltd., the Group’s partner for commercialisation in Japan, submitted its New Drug Application (NDA) for ACTAIR, an investigational allergy immunotherapy sublingual tablet for the treatment of HDM-induced allergic rhinitis in children from 5 through 11 years of age. ACTAIR is already approved for the treatment of HDM-induced allergic rhinitis in patients from 12 years old in Japan.

In June, a retrospective analysis from a prescription database in Germany including over 74,000 patients was presented at the EAACI² Congress. The data showed that grass pollen SLIT (sublingual immunotherapy) treatment, including ORALAIR can help control allergic rhinitis and may reduce the risk of the onset and progression of allergic asthma. This is the first study of our BREATH program (Bringing Real-world Evidence for Allergy Treatment to Health), a comprehensive program to strengthen evidence of AIT benefits for patients and payers.

In July, the Group completed enrolment of its phase III clinical study to evaluate the safety and efficacy of its investigational sublingual immunotherapy tablet STG320 for the treatment of house dust mite (HDM) induced allergic rhinitis. The study recruited over 1,600 patients from 13 countries with 231 participating investigative sites and is the largest study of its kind. This phase III study, together with other clinical data, will form the company’s submission for a Biologics License Application (BLA) in the United States planned for 2019 and for additional marketing authorisations in European and International markets. To date, the product is already commercialised in Japan, Australia and South Korea.

Manufacturing

In December 2016, the Group received a three-year GMP (Good Manufacturing Practice) certificate for its site in Antony (France) that was impacted by a temporary production and distribution suspension late 2015.

In June 2017, the Group’s manufacturing sites in in San Diego (CA, United States) and in Lenoir (NC, United States) successfully completed a FDA (US Food and Drug Administration) inspection.

Business Outlook and Guidance¹

The Group continues to deliver on its operations and commercial priorities with an increased focus on cost control. For the second half of the year, the Group is focusing on continuing to rebuild trust with all stakeholders, rightsizing the organisation including hiring for key positions, regaining global market leadership and investing wisely to support innovation and sustainable growth.

Considering the good start of the year with market share regain, operational successes and the positive EBITDA in the first half of 2017, Stallergenes Greer:

• narrowed its 2017 revenue guidance¹ to €260-€270m versus €240-€270m; and
• continuing positive development of EBITDA
