Joint Statement from the Chairman and Chief Executive Officer

Operating Review

Overview

The Group has continued to outperform in most markets, with Spain and the Emerging Markets being the largest contributors. During the first six months of the year, the Group's revenues grew by 1.3% at constant currency and 4.4% in actual terms, notwithstanding an abnormally weak pollen season in Central European markets which affected Germany, Austria and Switzerland. The continued growth in these more challenging market conditions reflects the quality of the Group's highly convenient, aluminium-free therapy and enabled the Group to continue to gain market share.

Furthermore, one of the management team's stated aims is to leverage the Group's current infrastructure, and this is demonstrated by continued expansion of pre-R&D operating profit, growing 12% to £12.3m (H1 2017: £11.1m).

The Market

Allergy Therapeutics continues to gain market share in its core European markets. In the year to 31 December 2017, our German market share grew to 14% compared to 13% in the year ended 30 June 2017. The revenue growth achieved in the first half of the year clearly shows the strength and continued penetration of the Pollinex portfolio in testing circumstances experienced across the market. The advantage of the breadth of our innovative portfolio has also been illustrated with continued strong growth in Venomil, the Group's leading bee and wasp venom product, and Acarovac PlusTM. Acarovac PlusTM is now the best-selling Group product in the Spanish market. The results are in line with the Group's target of achieving 20% market share in the coming years on the basis of the focused sales and marketing strategy and continued growth of the newer products in our portfolio.

The abnormally weak pollen season that occurred last year usually occurs every few years and management currently expects that the 2018 pollen season should return to normal levels. Weather patterns and pollution mainly determine the strength of a pollen season and we are pleased that despite the weakness of the season in 2018, we have continued to achieve growth.

The benefits of the investments made in the broader supply chain to ensure high quality and robustness continues to be shown. The Group expects that the markets and the associated regulatory environment will continue to evolve as further countries within the EU enact legislation similar to the TAV process in Germany.

Regulatory Affairs & Clinical Development

Good progress continues to be made in the German TAV (Therapy Allergy Ordinance) process. As disclosed in January, the Group has now completed recruitment and started treating patients in its pivotal Phase III Pollinex Quattro Birch study in Europe (B301), which is expected to read out in H2 2018. If successful, and if approved, the next step is expected to lead to a market authorisation.

With the Oralvac products in the TAV process, the Group has signed a co-development agreement with Ergomed plc and expects to announce the start of Phase I trials within the calendar year.

We are pleased to report that all ten of the Group's products which were submitted to the TAV process are still in development. In terms of the wider competitive landscape, the data available show that 40% of all the products that were on the market and submitted for the TAV process have dropped out and are no longer allowed to be sold in Germany (PEI Seminar, Bad Homberg, 6-9 Sept 2017).

As announced in February, the Grass MATA MPL Phase II dosing study for the US (G205) using conjunctival provocation has completed recruitment ahead of schedule and the enrolled patients have started treatment. The trial is taking place in Europe and is expected to read out in early H2 2018 ahead of a planned pivotal Phase III trial (G306). This product, if it successfully completes clinical trials and gains approval, will form the platform for expansion into the lucrative US market.

The Phase I trial for Acarovac MPL (AM101), a subcutaneous house dust mite immunotherapy using the Pollinex Quattro technology platform, has begun and is expected to read out in H1 2019, slightly later than previously reported.

Bencard Adjuvant Systems continues to build its IP assets with microcrystalline tyrosine (MCT) manufacturing process patented in key worldwide markets including the US, EU, China and Japan.

Polyvac Peanut

In February 2018, the Group also announced that it has signed an agreement with AGC Biologics to scale up Polyvac Peanut manufacturing in advance of first clinical trials. The Group still expects to begin Phase I trials in 2019, subject to successful scale-up, dosing analysis and discussions with the regulatory authorities. This product uses the virus-like particles (VLP) technology which is new in the allergy field but has been successfully applied in other fields of immunology such as with a hepatitis B vaccine.

The US peanut allergy market is potentially worth U$8bn (The Journal of Allergy and Clinical Immunology, 2016). Unlike other candidate products that require a long treatment period, Polyvac Peanut is being developed as an ultra-short course treatment that will improve adherence and convenience consistent with the rest of the Group portfolio.

Financial Review

Reported revenues for the first half of the financial year were £42.2m (H1 2017: £40.4m), representing a growth of 1.3% at constant currency, despite the abnormally weak pollen season in Central Europe. The growth rate reported after taking into account currency movements was 4.4% with the positive impact on revenues from the strengthening euro being £1.3m (H1 2017: £6.2m). The sales growth has been driven primarily by the Group's investment in infrastructure and broadening of the product portfolio as it continues to increase its market share in all of its main markets.

A reconciliation between reported revenues and revenues in constant currency is provided in the table below:

As in previous years, owing to the seasonality of the pollen allergy market, between 60% to 70% of Allergy Therapeutics' revenues are generated in the first half of the financial year and, as a consequence, the Group typically records profits in the first half of the year and losses in the second half.

Cost of goods sold decreased marginally in the period to £8.7m (H1 2017: £8.9m), mainly due to cost efficiencies with higher volumes in the factory in advance of manufacturing of the clinical trial products. Gross profit increased to £33.5m (H1 2017: £31.5m), which represents a gross margin of 79% (H1 2017: 78%), reflecting lower costs of goods.

Sales, marketing and distribution costs of £14.2m (H1 2017: £13.8m) were higher than the previous period due to the impact of the strong euro. Administration expenses of £7.1m (H1 2017: £6.6m) also rose due to the impact of the euro and inflation.

Research and development costs of £5.9m (H1 2017: £3.8m) reflected the higher level of activity in H1 2018 due to the Grass MATA MPL Phase II and the PQ Birch Phase III trials.

The tax charge in the period of £0.4m (H1 2017: £0.4m) relates to overseas subsidiaries.

Property, plant and equipment was unchanged in the period but increased by £0.1m to £9.8m compared to the year before, mainly as a result of investment in new plant and equipment to increase capacity and efficiency and improvements to the Worthing offices. The depreciation charge increased by £0.2m, reflecting this investment in the plant. Goodwill remained broadly unchanged at £3.4m (H1 2017: £3.4m), whilst other intangible assets have decreased by £0.3m.

Total current assets excluding cash have increased by £1.6m to £19.3m (H1 2017: £17.7m). This is mainly due to an increase in debtors reflecting the higher sales and the different sales channel used for Synbiotics.

Retirement benefit obligations, which relate solely to the German pension scheme, increased to £10.1m (H1 2017: £9.6m) as a result of the movement in the sterling-euro exchange rate as well as the reduction in the discount rate.

Net cash generated by operations was positive although lower than last year, due to higher R&D spending in H1 2018 as well as the strong trading result helped by the sterling-euro exchange rate, with a reported inflow of £4.3m (H1 2017: £5.4m).

Financing

The Group had debt on its balance sheet at the close of the financial year relating to loans held in the Spanish subsidiary of £3.2m (H1 2017: £3.4m). The seasonal overdraft was not used during the calendar year 2017 but the Group expects to renew its banking facilities when they are due for review in April 2018. The Group did not draw down any debt from its facility in Spain during the period (H1 2017: £0.1m).

The Directors believe that the Group will have adequate facilities for the foreseeable future and, accordingly, they have applied the going concern principle in preparing these interim financial statements.

Movements in the currency markets between the respective values of the euro and sterling have an effect on the Group's operations. The Group manages its cash exposure in this respect by foreign currency hedges. Over 90% of our gross sales are denominated in euros whereas approximately 50% of costs are incurred in the United Kingdom and denominated in sterling.

Other Matters

As disclosed in Note 4 (Contingent liabilities), on 23 February 2015, the Company received notification that The Federal Office for Economics and Export ("BAFA") had made a decision to reverse its preliminary exemption to the increased manufacturers rebate in Germany for the period July to December 2012. The Company was granted a preliminary exemption to the increased rebate for this period by BAFA in 2013. The Company recognised revenue of €1.4m (£1.1m at that time, now £1.2m) against this exemption in the year ended 30 June 2013. All other preliminary exemptions (granted for periods up to 30 June 2012) have previously been ratified as final by BAFA. After taking legal advice, the Company has lodged an appeal against this decision and is confident that the exemption will be re-instated. Therefore, as at 31 December 2017, no provision has been recognised for the repayment of the rebate refund. This position will be kept under review.

The European Commission has concluded its investigation into whether the exemption of pharmaceutical manufacturers from the increase in rebates in Germany constitutes state aid. The European Commission has determined that the exemptions do not constitute state aid. Subsequent to this announcement, the Group has been advised that an appeal has been lodged at the EU Court against this decision. If successful, and the exemptions are determined to be illegal state aid, then the exemption refunds may have to be repaid. The maximum sum to be repaid would be approximately £5m (including the £1.2m referred to above); however, the Group considers this to be an unlikely outcome and consequently has not recognised any provision as a result.

The Group is in a legal process with one of its suppliers and their lawyers over potential cost overruns on one of its clinical trials which may lead to additional expense for the Group.

Outlook

This year is set to be pivotal for Allergy with the key Grass MATA MPL Phase II trial on course for readout in the second half of the calendar year as expected. This could provide us the platform to expand into the lucrative US market.

The Board and management team expect that growth in net sales will continue ahead of wider market trends in the second half of the year and have great confidence in the future of the business. As planned, research and development costs are expected to double in the second half of the year compared to the first half, reflecting the period of maximum activity of two major trials (US Grass MATA MPL Phase II and PQ Birch Phase III) with the intention of significantly expanding our addressable market. Our continued focus on new product development is illustrated by our work on Polyvac Peanut. Whilst at an early stage, we believe that our well-established, innovative approach to immunising patients from allergy symptoms could provide a new approach to combating this severe affliction. Other costs are expected to be slightly higher than H1 2018.

The Group is well positioned to continue to grow the European business while developing the pipeline for the US market and expanding into other allergy fields.

We look forward to the future with confidence.

Consolidated statement of changes in equity

1. Interim financial information

The unaudited consolidated interim financial information is for the six month period ended 31 December 2017. The financial information does not include all the information required for full annual financial statements and should be read in conjunction with the consolidated financial statements of the Group for the year ended 30 June 2017, which were prepared under International Financial Reporting Standards (IFRS) as adopted by the European Union (EU).

The interim financial information has not been audited nor has it been reviewed under ISRE 2410 of the Auditing Practices Board. The financial information set out in this interim report does not constitute statutory accounts as defined in Section 434 of the Companies Act 2006. The Company's statutory financial statements for the year ended 30 June 2017 prepared under IFRS have been filed with the Registrar of Companies. The auditor's report on those financial statements was unqualified and did not contain a statement under Section 498(2) of the Companies Act 2006.

2. Basis of preparation

The interim financial statements have been prepared in accordance with applicable accounting standards and under the historical cost convention except for land and buildings and derivative financial instruments which have been measured at fair value. The accounting policies adopted in this report are consistent with those of the annual financial statements for the year to 30 June 2017 as described in those financial statements. There are no accounting standards that have become effective in the current period that would have a material impact upon the financial statements.

Going Concern

The Group has been profit making in the six months to 31 December 2017, as it was in the corresponding period ending 31 December 2016.

Detailed budgets have been prepared, including cash flow projections for the periods ending 30 June 2018 and 30 June 2019. These projections include assumptions on the trading performance of the operating business and the continued availability of the existing bank facilities. The Group had a cash balance of £25.8m at 31 December 2017 and expects to renew its banking facilities when they are due for renewal in April 2018. After making appropriate enquiries, which included a review of the annual budget and latest forecast, by considering the cash flow requirements for the foreseeable future and the effects of sales and other sensitivities on the Group's funding plans, the Directors continue to believe that the Group will have adequate resources to continue in operational existence for the foreseeable future and accordingly have applied the going concern principle in preparing these interim financial statements.

3. Earnings per share

4. Contingent liabilities

On 23 February 2015, the Company received notification that The Federal Office for Economics and Export ("BAFA") had made a decision to reverse their preliminary exemption to the increased manufacturers rebate in Germany for the period July to December 2012. The Company was granted a preliminary exemption to the increased rebate for this period by BAFA in 2013. The Company recognised revenue of €1.4m (£1.1m at that time, now £1.2m) against this exemption in the year ended 30 June 2013. All other preliminary exemptions (granted for periods up to 30 June 2012) have previously been ratified as final by BAFA. After taking legal advice, the Company has lodged an appeal against this decision and is confident that the exemption will be re-instated. Therefore, as at 31 December 2017, no provision has been recognised for the repayment of the rebate refund. This position will be kept under review.

The European Commission has concluded its investigation into whether the exemption of pharmaceutical manufacturers from the increase in rebates in Germany constitutes state aid. The European Commission has determined that the exemptions do not constitute state aid. Subsequent to this announcement, the Group has been advised that an appeal has been lodged at the EU Court against this decision.
