 The Total results are presented under 'Financial performance' on 
  pages 12 and 28 and Adjusted results reconciliations are presented 
  on pages 24, 25, 38 and 39. Adjusted results are a non-IFRS measure 
  that may be considered in addition to, but not as a substitute for, 
  or superior to, information presented in accordance with IFRS. Adjusted 
  results are defined on page 10 and GBP% or AER% growth, CER% growth, 
  free cash flow and other non-IFRS measures are defined on page 67. 
  GSK provides guidance on an Adjusted results basis only, for the 
  reasons set out on page 11. All expectations, guidance and targets 
  regarding future performance and dividend payments should be read 
  together with 'Outlook, assumptions and cautionary statements' on 
  pages 68 and 69. 
 *   Reported AER and CER growth rates include three and six months' 
      results of former Pfizer consumer healthcare business. Pro-forma 
      CER growth rates are calculated as if the equivalent three and 
      six months of Pfizer consumer healthcare business results, as reported 
      by Pfizer, were included in the comparative period of Q2 2019 and 
      H1 2019 respectively. See 'Pro-forma growth' on page 11. 
 
 
 Emma Walmsley, Chief Executive Officer, GSK said: 
  " The fundamentals of GSK's business remain strong and we are maintaining 
  good momentum on our strategic priorities. This quarter, we presented 
  promising data and had positive regulatory reviews for new speciality 
  pipeline medicines to treat HIV and Oncology; and made further progress 
  with our Consumer Healthcare integration and Future Ready programmes, 
  both of which will prepare the company for separation. 
 
  "We continue to believe that multiple options will be needed to prevent 
  and treat COVID-19 and are working at pace with our partners to develop 
  potential adjuvanted vaccines and therapeutics to fight the virus. 
  At the same time, we have made strategic investments in next-generation 
  vaccine and antibody technologies, most recently through our new 
  collaboration with CureVac. 
 
  "As expected, our performance this quarter was disrupted by COVID-19, 
  particularly in our Vaccines business, as visits to healthcare professionals 
  were limited due to lockdown measures. Overall, we are seeing good 
  underlying demand for our major products and are confident this will 
  be reflected in future performance when the impact of COVID measures 
  eases." 
 
 
 2020 guidance 
 At the time of announcing full-year 2019 results on 5 February 2020 
  we provided guidance with respect to expected full-year 2020 Adjusted 
  EPS, being a decline in the range of -1% to -4% at CER. 
 
  This guidance reflected our expectations for growth in key new products, 
  and the start of a two-year period in which we would continue to 
  increase investment in these products and in our R&D pipeline, alongside 
  implementation of our new programme which will prepare the Group 
  for separation. 
 
  The guidance excluded any impact in 2020 from any further material 
  divestments beyond those previously announced and any potential impact 
  on our business from the Coronavirus outbreak. 
 
  The COVID-19 pandemic has impacted Group performance during the first 
  half of 2020. As we anticipated, in Q2 2020 performance was disrupted, 
  particularly in the Vaccines business, as visits to healthcare professionals 
  were limited due to containment measures. 
 
  While we are maintaining our 2020 Adjusted EPS guidance, there remain 
  notable risks to business performance over the balance of the year. 
  In particular, the outcome is dependent on the timing of a recovery 
  in vaccination rates, particularly in the US, which we anticipate 
  in the third quarter. If we were to experience a delay in this recovery 
  we could see a significant impact in 2020. In the case of, for example, 
  a three month delay, the impact on adjusted EPS would be up to 5 
  percentage points. 
 
  All expectations, guidance and targets regarding future performance 
  and dividend payments should be read together with 'Outlook, assumptions 
  and cautionary statements' on pages 68 and 69. If exchange rates 
  were to hold at the closing rates on 30 June 2020 ($1.23/GBP1, EUR1.10/GBP1 
  and Yen 132/GBP1) for the rest of 2020, the estimated impact on 2020 
  Sterling turnover growth would be around flat and if exchange gains 
  or losses were recognised at the same level as in 2019, the estimated 
  impact on 2020 Sterling Adjusted EPS growth would also be around 
  flat.

 Group turnover was GBP7,624 million in the quarter, down 2% AER, 
  3% CER and 10% CER on a pro-forma basis . 
  On a pro-forma basis, Group turnover was down 10% CER, and down 
  8% CER excluding the impact of divestments in Vaccines and brands 
  divested or under review in Consumer Healthcare. Sales decline reflects 
  expected disruption from COVID-19, particularly in Vaccines as well 
  as destocking from Q1 2020 in Pharmaceuticals and Consumer Healthcare. 
 
  Pharmaceuticals turnover in the quarter was GBP4,102 million, down 
  5% AER, 5% CER. HIV sales were down 2% AER, 3% CER, to GBP1,185 
  million, with growth in Juluca and Dovato offset by declines in 
  Tivicay and Triumeq including destocking. Respiratory sales were 
  up 17% AER, 16% CER, to GBP883 million, on growth of Trelegy and 
  Nucala. Sales of Established Pharmaceuticals declined 17% AER, 17% 
  CER, to GBP1,780 million, reflecting destocking and lower demand 
  for antibiotics due to COVID-19. 
 
  Vaccines turnover declined 29% AER, 29% CER to GBP1,133 million, 
  primarily driven by the adverse impact of the COVID-19 pandemic 
  on DTPa-containing, Hepatitis, Shingles and Meningitis vaccines, 
  together with the Rabipur and Encepur divestment. 
 
  Reported Consumer Healthcare sales grew 25% AER, 25% CER to GBP2,389 
  million in the quarter, largely driven by the inclusion of the Pfizer 
  portfolio. On a pro-forma basis, sales declined 6% CER, and were 
  flat at CER excluding brands divested/under review, including reversal 
  of stockbuilding in Q1 2020. 
 
  Operating profit 
  Total operating profit was GBP2,850 million in Q2 2020 compared 
  with GBP1,484 million in Q2 2019. The total operating margin was 
  37.4%. Adjusted operating profit was GBP1,749 million, down 19% 
  AER, 21% CER on a turnover decrease of 3% CER. The Adjusted operating 
  margin was 22.9%. On a pro-forma basis, Adjusted operating profit 
  was 27% lower at CER on a turnover decrease of 10% CER. The pro-forma 
  Adjusted operating margin was 22.9%. 
 
  The increase in Total operating profit reflected the profit on disposal 
  of the Horlicks and other Consumer Healthcare brands and resultant 
  sale of shares in Hindustan Unilever with increased income from 
  asset disposals. This was partly offset by higher re-measurement 
  charges on the contingent consideration liabilities. The decrease 
  in pro-forma Adjusted operating profit primarily reflected reduced 
  leverage from the reduction in sales across all three businesses, 
  continuing price pressures particularly in Respiratory and an increase 
  in R&D investment. 
 
  Earnings per share 
  Total EPS was 45.5p, compared with 19.5p in Q2 2019. The increase 
  in EPS primarily reflected the net profit on disposal of Horlicks 
  and other Consumer Healthcare brands as well as increased income 
  from asset disposals, partly offset by higher re-measurement charges 
  on the contingent consideration liabilities and lower operating 
  performance as a result of COVID-19 impact on the Vaccines business 
  and destocking in Pharmaceuticals and Consumer Healthcare following 
  a strong operating performance in Q1 2020. 
 
  Adjusted EPS was 19.2p compared with 30.5p in Q2 2019, down 37% 
  AER, 38% CER. This reduction primarily resulted from lower sales 
  and a higher non-controlling interest allocation of Consumer Healthcare 
  profits and a higher effective tax rate. 
 
  Cash flow 
  The net cash inflow from operating activities for the quarter was 
  GBP2,760 million (Q2 2019: GBP1,389 million) and free cash flow 
  was GBP1,949 million (Q2 2019: GBP370 million). The increase primarily 
  reflected a significant reduction in trade receivables as a result 
  of collections following strong sales in Q1, the beneficial timing 
  of payments for returns and rebates and taxes, higher disposals 
  of intangible assets partly offset by reduced operating profits, 
  increased inventory and higher dividends to non-controlling interests.

 Group turnover was GBP16,714 million in the six months up 8% AER, 
  8% CER and flat on a pro-forma basis. 
  On a pro-forma basis, Group turnover was flat, and up 1% excluding 
  the impact of divestments in Vaccines and brands divested or under 
  review in Consumer Healthcare. Sales performance reflects disruption 
  from COVID-19 primarily in vaccines in Q2 2020. 
 
  Pharmaceuticals turnover in the six months was GBP8,498 million, 
  flat at both AER and CER. HIV sales were up 3% AER, 2% CER, to GBP2,392 
  million, with growth in Juluca and Dovato partly offset by declines 
  in Tivicay and Triumeq. Respiratory sales were up 27% AER, 26% CER, 
  to GBP1,754 million, on growth of Trelegy and Nucala. Sales of Established 
  Pharmaceuticals declined 12% AER, 11% CER to GBP3,866 million, reflecting 
  lower demand for antibiotics in the COVID-19 period. 
 
  Vaccines turnover declined 5% AER, 6% CER to GBP2,938 million, primarily 
  driven by the adverse impact of the COVID-19 pandemic on Hepatitis, 
  DTPa-containing, Meningitis and Shingles vaccines, partially offset 
  by growth in Shingrix in Q1 2020. 
 
  Reported Consumer Healthcare sales grew 35% AER, 36% CER to GBP5,251 
  million in the six months, largely driven by the inclusion of the 
  Pfizer portfolio. On a pro-forma basis, sales grew 2% CER, and 7% 
  CER excluding brands divested/under review. 
 
 
 Operating profit 
  Total operating profit was GBP4,864 million compared with GBP2,912 
  million in H1 2019. Adjusted operating profit was GBP4,424 million, 
  up 2% AER, 2% CER on a turnover increase of 8% CER. The Adjusted 
  operating margin of 26.5% was 1.5 percentage points lower at AER, 
  and 1.7 percentage points lower on a CER basis than in H1 2019. 
  The pro-forma Adjusted operating margin was 26.5%. 
 
  The reduction in pro-forma Adjusted operating profit primarily reflected 
  the adverse impact from the reduction in sales in Vaccines as a 
  result of the COVID-19 pandemic, continuing price pressure, particularly 
  in Respiratory, investment in R&D , and investments in promotional 
  product support, particularly for new launches in Vaccines, HIV 
  and Respiratory. This was partly offset by a favourable mix in Vaccines, 
  reduced promotional and variable spending across all three business 
  as a result of the COVID-19 lockdowns, the continuing benefit of 
  restructuring in Pharmaceuticals and Consumer Healthcare and the 
  tight control of ongoing costs, particularly in non-promotional 
  spending across all three businesses. 
 
  Earnings per share 
  Total EPS was 77.0p, compared with 36.3p in H1 2019. The increase 
  in EPS primarily reflected the net profit on disposal of Horlicks 
  and other Consumer Healthcare brands as well as increased income 
  from asset disposals, partly offset by higher re-measurement charges 
  on the contingent consideration liabilities and a one-off benefit 
  in H1 2019 from the increased share of after tax profits of the 
  associate Innoviva. 
 
  Adjusted EPS was 56.9p compared with 60.6p in H1 2019, down 6% AER, 
  6% CER. The reduction primarily resulted from a higher non-controlling 
  interest allocation of Consumer Healthcare profits, reduced share 
  of after tax profits of associates resulting from a non-recurring 
  income tax benefit in Innoviva partly offset by a reduced effective 
  tax rate. 
 
  Cash flow 
  The net cash inflow from operating activities for the six months 
  was GBP3,725 million (H1 2019: GBP2,052 million) and free cash flow 
  was GBP2,480 million for the six months (H1 2019: GBP535 million). 
  The increase primarily reflected a reduction in trade receivables 
  as a result of collections following strong sales in Q1 2020, the 
  beneficial timing of payments for returns and rebates and taxes, 
  a lower seasonal increase of inventory, improved operating profits 
  and higher disposals of intangible assets and milestone income.

 Total and Adjusted results 
 
 
 Total reported results represent the Group's overall performance. 
 
  GSK also uses a number of adjusted, non-IFRS, measures to report 
  the performance of its business. Adjusted results and other non-IFRS 
  measures may be considered in addition to, but not as a substitute 
  for or superior to, information presented in accordance with IFRS. 
  Adjusted results are defined below and pro-forma growth and other 
  non-IFRS measures are defined on page 67. 
 
  GSK believes that Adjusted results, when considered together with 
  Total results, provide investors, analysts and other stakeholders 
  with helpful complementary information to understand better the 
  financial performance and position of the Group from period to period, 
  and allow the Group's performance to be more easily compared against 
  the majority of its peer companies. These measures are also used 
  by management for planning and reporting purposes. They may not 
  be directly comparable with similarly described measures used by 
  other companies. 
 
  GSK encourages investors and analysts not to rely on any single 
  financial measure but to review GSK's quarterly results announcements, 
  including the financial statements and notes, in their entirety. 
 
  GSK is committed to continuously improving its financial reporting, 
  in line with evolving regulatory requirements and best practice. 
  In line with this practice, GSK expects to continue to review and 
  refine its reporting framework. 
 
  Adjusted results exclude the following items from Total results, 
  together with the tax effects of all of these items: 
 
 
 --   amortisation of intangible assets (excluding computer software) 
 --   impairment of intangible assets (excluding computer software) and 
       goodwill 
 --   Major restructuring costs, which include impairments of tangible 
       assets and computer software, (under specific Board approved programmes 
       that are structural, of a significant scale and where the costs 
       of individual or related projects exceed GBP25 million), including 
       integration costs following material acquisitions 
 --   transaction-related accounting or other adjustments related to 
       significant acquisitions 
 --   proceeds and costs of disposal of associates, products and businesses; 
       significant legal charges (net of insurance recoveries) and expenses 
       on the settlement of litigation and government investigations; 
       other operating income other than royalty income, and other items 
 --   separation costs 
 
 
 Costs for all other ordinary course smaller scale restructuring 
  and legal charges and expenses are retained within both Total and 
  Adjusted results. 
 
  As Adjusted results include the benefits of Major restructuring 
  programmes but exclude significant costs (such as significant legal, 
  major restructuring and transaction items) they should not be regarded 
  as a complete picture of the Group's financial performance, which 
  is presented in Total results. The exclusion of other Adjusting 
  items may result in Adjusted earnings being materially higher or 
  lower than Total earnings. In particular, when significant impairments, 
  restructuring charges and legal costs are excluded, Adjusted earnings 
  will be higher than Total earnings. 
 
  GSK has undertaken a number of Major restructuring programmes in 
  response to significant changes in the Group's trading environment 
  or overall strategy, or following material acquisitions. Costs, 
  both cash and non-cash, of these programmes are provided for as 
  individual elements are approved and meet the accounting recognition 
  criteria. As a result, charges may be incurred over a number of 
  years following the initiation of a Major restructuring programme. 
 
  Significant legal charges and expenses are those arising from the 
  settlement of litigation or government investigations that are not 
  in the normal course and materially larger than more regularly occurring 
  individual matters. They also include certain major legacy matters. 
 
  Reconciliations between Total and Adjusted results, providing further 
  information on the key Adjusting items, are set out on pages 24, 
  25, 38 and 39. 
 
  GSK provides earnings guidance to the investor community on the 
  basis of Adjusted results. This is in line with peer companies and 
  expectations of the investor community, supporting easier comparison 
  of the Group's performance with its peers. GSK is not able to give 
  guidance for Total results as it cannot reliably forecast certain 
  material elements of the Total results, particularly the future 
  fair value movements on contingent consideration and put options 
  that can and have given rise to significant adjustments driven by 
  external factors such as currency and other movements in capital 
  markets. 
 
 
 Pro-forma growth 
  The acquisition of the Pfizer consumer healthcare business completed 
  on 31 July 2019 and so GSK's reported results for Q2 2020 include 
  three months of results of the former Pfizer consumer healthcare 
  business from 1 April 2020. 
  The Group has presented pro-forma growth rates at CER for turnover, 
  Adjusted operating profit and operating profit by business taking 
  account of this transaction. Pro-forma growth rates for the quarter 
  are calculated comparing reported results for Q2 2020, calculated 
  applying the exchange rates used in the comparative period, with 
  the results for Q2 2019 adjusted to include the equivalent three 
  months of results of the former Pfizer consumer healthcare business 
  during Q2 2019, as consolidated (in US$) and included in Pfizer's 
  US GAAP results. Similarly, pro-forma growth rates at CER for the 
  six months to 30 June 2020 are calculated comparing reported results 
  for the six months to 30 June 2020, calculated applying the exchange 
  rates used in the comparative period, with the results for the six 
  months to 30 June 2019, adjusted to include the equivalent six months 
  of results of the former Pfizer consumer healthcare business, as 
  consolidated (in US$) and included in Pfizer's US GAAP results. 
  ViiV Healthcare 
  ViiV Healthcare is a subsidiary of the Group and 100% of its operating 
  results (turnover, operating profit, profit after tax) are included 
  within the Group income statement. 
  Earnings are allocated to the three shareholders of ViiV Healthcare 
  on the basis of their respective equity shareholdings (GSK 78.3%, 
  Pfizer 11.7% and Shionogi 10%) and their entitlement to preferential 
  dividends, which are determined by the performance of certain products 
  that each shareholder contributed. As the relative performance of 
  these products changes over time, the proportion of the overall earnings 
  allocated to each shareholder also changes. In particular, the increasing 
  proportion of sales of dolutegravir-containing products has a favourable 
  impact on the proportion of the preferential dividends that is allocated 
  to GSK. Adjusting items are allocated to shareholders based on their 
  equity interests. GSK was entitled to approximately 85% of the Total 
  earnings and 82% of the Adjusted earnings of ViiV Healthcare for 
  2019. 
  As consideration for the acquisition of Shionogi's interest in the 
  former Shionogi-ViiV Healthcare joint venture in 2012, Shionogi received 
  the 10% equity stake in ViiV Healthcare and ViiV Healthcare also 
  agreed to pay additional future cash consideration to Shionogi, contingent 
  on the future sales performance of the products being developed by 
  that joint venture, principally dolutegravir. Under IFRS 3 'Business 
  combinations', GSK was required to provide for the estimated fair 
  value of this contingent consideration at the time of acquisition 
  and is required to update the liability to the latest estimate of 
  fair value at each subsequent period end. The liability for the contingent 
  consideration recognised in the balance sheet at the date of acquisition 
  was GBP659 million. Subsequent re-measurements are reflected within 
  other operating income/expense and within Adjusting items in the 
  income statement in each period. At 30 June 2020, the liability, 
  which is discounted at 8.5%, stood at GBP5,436 million, on a post-tax 
  basis. 
  Cash payments to settle the contingent consideration are made to 
  Shionogi by ViiV Healthcare each quarter, based on the actual sales 
  performance of the relevant products in the previous quarter. These 
  payments reduce the balance sheet liability and hence are not recorded 
  in the income statement. The cash payments made to Shionogi by ViiV 
  Healthcare in H1 2020 were GBP445 million. 
  Because the liability is required to be recorded at the fair value 
  of estimated future payments, there is a significant timing difference 
  between the charges that are recorded in the Total income statement 
  to reflect movements in the fair value of the liability and the actual 
  cash payments made to settle the liability. 
  Further explanation of the acquisition-related arrangements with 
  ViiV Healthcare are set out on pages 50 and 51 of the Annual Report 
  2019.

 Pharmaceuticals turnover in the quarter was GBP4,102 million, down 
  5% AER, 5% CER. HIV sales were down 2% AER, 3% CER, to GBP1,185 million, 
  with growth in Juluca and Dovato offset by declines in Tivicay and 
  Triumeq. Respiratory sales were up 17% AER, 16% CER, to GBP883 million, 
  on growth of Trelegy and Nucala. Sales of Established Pharmaceuticals 
  declined 17% AER, 17% CER, to GBP1,780 million. 
  In the quarter, as expected, the COVID-19 related first quarter customer 
  stockbuilding, which predominantly impacted Europe and the US, broadly 
  reversed with only a minor dolutegravir impact in Europe and the 
  US remaining. The quarter also saw lower levels of new patient prescriptions 
  in the US and Europe, reduced market demand for allergy and antibiotic 
  products in International and pressure on net prices in the US. 
  In the US, sales grew 1% AER but declined 1% CER. Continued growth 
  of Nucala, Trelegy, Benlysta and the HIV two-drug regimens was more 
  than offset by the decline and COVID-19 destocking in Tivicay, Triumeq 
  and Established Pharmaceuticals, including the impact of generic 
  albuterol substitutes. 
  In Europe, sales declined 10% AER, 11% CER, reflecting the impact 
  of destocking and generic competition and almost fully offsetting 
  the additional demand experienced in the first quarter related to 
  COVID-19. 
  International declined 8% AER, 7% CER, with Respiratory growth offset 
  by lower Established Pharmaceutical sales including the impact of 
  a weaker allergy season in Japan, lower Augmentin sales across the 
  region and lower sales in China. 
  Respiratory 
  Total Respiratory sales were up 17% AER, 16% CER, with strong growth 
  from Trelegy and Nucala in all regions. International Respiratory 
  sales grew 17% AER, 17% CER, including Nucala, up 42% AER, 31% CER, 
  and Relvar/Breo up 8% AER, 12% CER to GBP81 million. In Europe, Respiratory 
  sales grew 13% AER, 13% CER despite the impact of the reversal of 
  the customer stockbuilding in Q1 2020 related to the COVID-19 pandemic. 
  In the US, Trelegy and Nucala growth continued while Relvar/Breo 
  sales were down 11% AER, 12% CER, impacted by competitive pricing 
  pressures and the impact of generic Advair on the US ICS/LABA market. 
  Sales of Nucala were GBP241 million in the quarter and grew 24% AER, 
  21% CER, with US sales up 28% AER, 26% CER to GBP150 million. Europe 
  sales of GBP54 million grew 4% AER, 6% CER and International sales 
  of GBP37 million grew 42% AER, 31% CER including growth of the at-home 
  use application. 
  Trelegy sales were up 62% AER, 58% CER to GBP194 million with strong 
  growth in all regions. In the US, sales grew 65% AER, 60% CER, reflecting 
  continued market share growth. In Europe, sales grew 64% AER, 59% 
  CER and in International sales grew 38% AER, 46% CER. 
  Relvar/Breo sales were up 2% AER, 2% CER to GBP242 million in the 
  quarter. In the US, Relvar/Breo declined 11% AER, 12% CER, reflecting 
  competitive pricing pressures and the impact of generic Advair on 
  the US ICS/LABA market. In Europe and International, Relvar/Breo 
  continued to grow, up 11% AER, 9% CER and 8% AER, 12% CER, respectively. 
  HIV 
  HIV sales were GBP1,185 million, down 2% AER, 3% CER in the quarter. 
  The dolutegravir franchise declined 1% AER, 2% CER, delivering sales 
  of GBP1,140 million. The remaining portfolio, with sales of GBP45 
  million and 4% of total HIV sales, declined 27% AER, 32% CER and 
  reduced the overall growth of total HIV by one percentage point. 
  Sales of dolutegravir products were GBP1,140 million in the quarter. 
  Sales were impacted by customer destocking following the customer 
  stockbuilding in Q1 2020 due to COVID-19, mainly on Tivicay and Triumeq. 
  Tivicay delivered sales of GBP373 million and declined 9% AER, 10% 
  CER. Triumeq delivered sales of GBP586 million and declined 9% AER, 
  11% CER. The two-drug regimens, Juluca and Dovato delivered sales 
  of GBP181 million in the quarter, with combined growth more than 
  offsetting the decline of the three-drug regimen Triumeq. 
  In the US, dolutegravir sales grew 1% AER, but declined 2% CER and 
  in Europe sales declined 4% AER, 5% CER impacted by customer destocking 
  following the customer stockbuilding in Q1 2020 due to COVID-19. 
  Following recent launches of Dovato, combined sales of the two-drug 
  regimens were GBP139 million in the US and GBP38 million in Europe, 
  with growth more than offsetting the decline in Triumeq. International 
  was flat at AER, but grew 4% CER, driven by Tivicay. 
  Oncology 
  Sales of Zejula, the PARP inhibitor asset acquired from Tesaro in 
  Q1 2019 were GBP77 million in the quarter, up 35% AER, 32% CER. Sales 
  comprised GBP47 million in the US and GBP30 million in Europe. 
  Immuno-inflammation 
  Sales of Benlysta in the quarter were up 18% AER, 15% CER to GBP177 
  million, including sales of the sub-cutaneous formulation of GBP89 
  million. In the US, Benlysta grew 16% AER, 14% CER to GBP153 million. 
  Established Pharmaceuticals 
  Sales of Established Pharmaceuticals in the quarter were GBP1,780 
  million, down 17% AER, 17% CER. 
  Established Respiratory products declined 12% AER, 12% CER to GBP805 
  million. This reflected the impact of generic albuterol substitutes 
  on Ventolin in the US, the impact of COVID-19 pandemic related destocking 
  in Europe and allergy market contraction in Japan. In the US, sales 
  of Advair/Seretide grew 36% AER, 34% CER to GBP143 million, reflecting 
  a spike in the ICS/LABA class during April and May. In Europe and 
  International, Seretide sales were down 12% AER, 13% CER and 7% AER, 
  6% CER, respectively, impacted by generic competition in Europe, 
  COVID-19 related destocking. 
  The remainder of the Established Pharmaceuticals portfolio declined 
  20% AER, 20% CER to GBP975 million on lower demand for Dermatology 
  products and Antibiotics during the COVID-19 pandemic period, the 
  impact of government mandated changes increasing the use of generics 
  in China, and comparison with a strong Q2 2019, which included a 
  European Relenza contract.

 Vaccines turnover declined 29% AER, 29% CER to GBP1,133 million, 
  primarily driven by the adverse impact of the COVID-19 pandemic on 
  DTPa-containing, Hepatitis, Shingles and Meningitis vaccines, together 
  with the Rabipur and Encepur divestment. 
 
  Vaccines performance in the second quarter across all regions was 
  affected by lower demand due to limited visits to healthcare practitioners 
  and points of vaccination during the pandemic and government stay-at-home 
  directives. In areas where government restrictions were lifted, wellness 
  visits and vaccination rates have started to recover, with paediatric 
  vaccinations returning to near pre-COVID-19 levels by the end of 
  the quarter, while adolescent and adult immunisations improved at 
  a slower pace. 
 
  Meningitis 
  Meningitis sales declined 29% AER, 29% CER to GBP167 million. Bexsero 
  and Menveo sales decreased 31% AER, 30% CER to GBP108 million and 
  39% AER, 39% CER to GBP38 million respectively, reflecting lower 
  demand across all regions due to de-prioritisation of vaccination 
  during the COVID-19 pandemic. In the US, Bexsero maintained and Menveo 
  grew market share. 
 
  Influenza 
  Fluarix/FluLaval sales were GBP15 million, down 12% AER, 6% CER. 
 
  Shingles 
  Shingrix sales declined 16% AER, 19% CER to GBP323 million, primarily 
  driven by lower adult wellness visits and vaccination rates related 
  to the COVID-19 pandemic stay-at-home directives in the US, partly 
  offset by favourable return and rebate movements in the US. Total 
  US prescriptions for Shingrix reflected partial recovery of demand 
  by the end of the quarter. In Europe, a strong performance was recorded 
  in Germany due to robust underlying demand in post-lockdown conditions. 
 
  Established Vaccines 
  Sales of DTPa-containing vaccines (Infanrix, Pediarix and Boostrix) 
  declined 42% AER, 43% CER. Infanrix/Pediarix sales declined 39% AER, 
  40% CER to GBP119 million, reflecting lower demand due to the COVID-19 
  pandemic conditions in the US, unfavourable year-on-year US CDC stockpile 
  movements and supply constraints in Europe. 
 
  Boostrix sales were down 47% AER, 47% CER to GBP76 million primarily 
  due to the negative impact of COVID-19 restrictions on vaccination 
  rates across all regions. 
 
  Hepatitis vaccines declined 62% AER, 62% CER to GBP86 million, adversely 
  impacted in the US and Europe by the COVID-19 pandemic and related 
  travel restrictions, together with competition returning to market 
  in the US. 
 
  Synflorix sales declined by 4% AER, 5% CER to GBP103 million, primarily 
  due to lower tender volume demand in Europe. 
 
  Rotarix sales were up 10% AER, 9% CER to GBP128 million, reflecting 
  favourable phasing in Emerging Markets and in International, partly 
  offset by lower demand in the US due to COVID-19 confinement measures. 
  MMRV vaccines sales grew 8% AER, 8% CER to GBP54 million, largely 
  driven by improved supply in Europe.

 On a reported basis, sales grew 25% AER, 25% CER to GBP2,389 million 
  in the quarter, largely driven by the inclusion of the Pfizer portfolio. 
  On a pro-forma basis, sales declined 6% CER and were flat at CER 
  excluding brands divested/under review. 
 
  At a regional level, China returned to growth as the mandated retailer 
  shutdowns were lifted, but weaker performance resulted due to the 
  expected unwinding of accelerated purchases seen in the previous 
  quarter, particularly in Europe and to a lesser extent in the US. 
  Quarterly sales growth also benefited by approximately two percentage 
  points, largely in the Digestive health and Pain relief categories, 
  from increased retailer stocking ahead of a systems cutover in North 
  America which is expected to reverse in the third quarter. The majority 
  of the benefit from the accelerated purchasing related to COVID-19 
  seen in the first quarter has now reversed, although Vitamins, minerals 
  and supplements continued to benefit from an increased consumer focus 
  on health and wellness. 
  Oral health 
  Oral health sales declined 2% AER, 1% CER to GBP639 million. Sensodyne 
  grew in low single-digits but continued to gain share, with growth 
  negatively impacted by the unwind of prior quarter accelerated purchases 
  which also affected Denture care and Gum health, and which has now 
  largely reversed. Overall growth was also impacted by a decline in 
  non-strategic brands. 
 
  Pain relief 
  Pain relief grew 38% AER, 38% CER to GBP529 million. On a pro-forma 
  basis, sales declined in low single digits. Continued strong performance 
  of Panadol, and the successful Rx to OTC switch and launch of Voltaren 
  OTC in the US, were partly offset by a weaker performance of Voltaren 
  in Europe. Overall performance was also impacted by the unwinding 
  of accelerated purchases seen in the prior quarter. 
  Vitamins, minerals and supplements 
  Vitamins, minerals and supplements more than doubled at AER and CER 
  to GBP404 million. On a pro-forma basis, sales grew in the high-teens 
  per cent, with strong performances from Centrum and Emergen-C, reflecting 
  continued strong consumer demand for the category, particularly in 
  the US and China. 
  Respiratory health 
  Respiratory health sales grew 9% AER, 8% CER to GBP214 million. On 
  a pro-forma basis, sales declined in low double-digits. Continued 
  growth of Theraflu was offset by the unwinding of accelerated purchases 
  seen in the previous quarter and reduced demand for seasonal nasal 
  spray products. 
  Digestive health and other 
  Digestive health and other brands grew 22% AER, 22% CER to GBP487 
  million. On a pro-forma basis, sales declined in low single digits, 
  reflecting continued weaker Skin health performance, the expected 
  unwinding of accelerated purchases of Digestive health and other 
  products, and also the impact of lower footfall, reducing impulse 
  purchases in retail stores due to the ongoing pandemic. 
 
 
 Operating performance 
 
 
 Cost of sales 
  Total cost of sales as a percentage of turnover was 32.1%, 1.6 percentage 
  points lower at AER and 1.5 percentage points lower in CER terms 
  compared with Q2 2019. This reflected a reduction in the costs of 
  Major restructuring programmes, primarily as a result of lower write 
  downs in a number of manufacturing sites. 
  Excluding these and other Adjusting items, Adjusted cost of sales 
  as a percentage of turnover was 29.5%, 0.8 percentage points higher 
  at AER and 1.0 percentage points higher at CER compared with Q2 2019. 
  On a pro-forma basis, Adjusted cost of sales as a percentage of turnover 
  was 29.5%, 0.7 percentage points higher at CER, compared with Q2 
  2019. This reflected unfavourable product mix in Vaccines, primarily 
  due to the decline of Shingrix in the US and in Consumer Healthcare 
  and continued adverse pricing pressure in Pharmaceuticals, particularly 
  in Respiratory, partly offset by lower inventory adjustments in Vaccines 
  and a further contribution from integration and restructuring savings 
  in Pharmaceuticals and Consumer Healthcare. 
  Selling, general and administration 
  Total SG&A costs as a percentage of turnover were 35.5%, 2.4 percentage 
  points higher at AER and 2.5 percentage points higher at CER compared 
  with Q2 2019. This included increased major restructuring costs partly 
  offset by lower significant legal and transaction costs. 
  Excluding these and other Adjusting items, Adjusted SG&A costs as 
  a percentage of turnover were 33.2%, 2.0 percentage points higher 
  at AER than in Q2 2019 and 2.2 percentage points higher on a CER 
  basis. On a pro-forma basis, Adjusted SG&A costs as a percentage 
  of turnover were 33.2%, 1.9 percentage points higher at CER, compared 
  with Q2 2019. 
  Adjusted SG&A costs grew 4% AER, 4% CER but declined 5% CER on a 
  pro-forma basis, which reflected reduced promotional and variable 
  spending across all three business as a result of the COVID-19 lockdowns 
  as well as the continuing benefit of restructuring in Pharmaceuticals 
  and Consumer Healthcare and the tight control of ongoing costs, partly 
  offset by increased investment for new launches in Respiratory and 
  HIV and an adverse comparison to income from favourable settlements 
  in Vaccines in Q2 2019. 
  Research and development 
  Total R&D expenditure was GBP1,301 million (17.1% of turnover), up 
  17% AER, 15% CER, including an increase in impairment charges. Adjusted 
  R&D expenditure was GBP1,171 million (15.4% of turnover), 13% higher 
  at AER, 11% higher at CER than in Q2 2019. On a pro-forma basis, 
  Adjusted R&D expenditure grew 9% CER compared with Q2 2019. 
  Pharmaceuticals R&D expenditure was GBP922 million, up 15% AER, 13% 
  CER, reflecting a continued significant increase in Oncology investment 
  across multiple mid and late-stage assets including the legacy Tesaro 
  portfolio and a number of other programmes including belantamab mafodotin, 
  ICOS and bintrafusp alfa. In addition to the Oncology investment 
  there has also been increased spending on the progression of key 
  assets in the Specialty and primary care portfolio such as otilimab 
  for RA, the initiation of several COVID-19 programmes as well as 
  on daprodustat which recently received approval in Japan. These increases 
  in investment were partly offset by reduced spending in HIV and the 
  ongoing benefits of the R&D portfolio re-prioritisation decisions 
  in 2019. R&D expenditure in Vaccines and Consumer Healthcare was 
  GBP175 million and GBP74 million, respectively. 
  Royalty income 
  Royalty income was GBP75 million (Q2 2019: GBP78 million), down 4% 
  AER, 10% CER, primarily reflecting adverse movements in Consumer 
  Healthcare. 
 
 
 Other operating income/(expense) 
  Net other operating income of GBP1,610 million (Q2 2019: GBP63 million 
  expense) primarily reflected the net profit on disposal in the quarter 
  of the Horlicks and other Consumer Healthcare brands of GBP2,304 
  million in Q2 2020, which was after reversal of GBP776 million of 
  embedded derivative gains on the value of the shares taken in prior 
  years and Q1 2020. This was partly offset by the related loss on 
  sale of the shares in Hindustan Unilever in Q2 2020 of GBP476 million. 
  Other operating income also included an increase in profit and milestone 
  income from a number of asset disposals. 
  The gains were partly offset by accounting charges of GBP368 million 
  (Q2 2019: GBP188 million) arising from the re-measurement of the 
  contingent consideration liabilities related to the acquisitions 
  of the former Shionogi-ViiV Healthcare joint venture and the former 
  Novartis Vaccines business and the liabilities for the Pfizer put 
  option and Pfizer and Shionogi preferential dividends in ViiV Healthcare. 
  This included a re-measurement charge of GBP343 million (Q2 2019: 
  GBP226 million) for the contingent consideration liability due to 
  Shionogi, primarily arising from changes in sales forecasts and exchange 
  rate assumptions as well as the unwind of the discounting. 
 
 
 Operating profit 
  Total operating profit was GBP2,850 million in Q2 2020 compared with 
  GBP1,484 million in Q2 2019. This reflected the profit on disposal 
  of the Horlicks and other Consumer Healthcare brands and resultant 
  sale of shares in Hindustan Unilever as well as increased income 
  from asset disposals. This was partly offset by higher re-measurement 
  charges on the contingent consideration liabilities. 
  Excluding these and other Adjusting items, Adjusted operating profit 
  was GBP1,749 million, 19% lower than Q2 2019 at AER and 21% lower 
  at CER on a turnover decrease of 3% CER. The Adjusted operating margin 
  of 22.9% was 4.9 percentage points lower at AER, and 5.1 percentage 
  points lower on a CER basis than in Q2 2019. On a pro-forma basis, 
  Adjusted operating profit was 27% lower at CER on a turnover decrease 
  of 10% CER. The Adjusted pro-forma operating margin of 22.9% was 
  5.3 percentage points lower on a CER basis than in Q2 2019. 
  The reduction in pro-forma Adjusted operating profit primarily reflected 
  the adverse impact from reduction in sales across all three businesses 
  as a result of the COVID-19 pandemic, including a reduction in customer 
  demand primarily in Vaccines and destocking in the quarter in Pharmaceuticals 
  and Consumer Healthcare and increased investment in R&D including 
  a significant increase in Oncology investments and initiation of 
  several COVID-19 programmes. In addition, there was adverse mix in 
  Vaccines and Consumer Healthcare, continuing price pressure, particularly 
  in Respiratory and increased investment for new launches in Respiratory 
  and HIV. This was partly offset by reduced promotional and variable 
  spending overall across all three businesses as a result of the COVID-19 
  lockdowns and the continued benefit of restructuring and tight control 
  of ongoing costs across all three businesses. 
  Contingent consideration cash payments which are made to Shionogi 
  and other companies reduce the balance sheet liability and hence 
  are not recorded in the income statement. Total contingent consideration 
  cash payments in Q2 2020 amounted to GBP240 million (Q2 2019: GBP226 
  million). This included cash payments made to Shionogi of GBP232 
  million (Q2 2019: GBP220 million). 
  Operating profit by business 
  Pharmaceuticals operating profit was GBP976 million, down 22% AER, 
  23% CER on a turnover decrease of 5% CER. The operating margin of 
  23.8% was 5.4 percentage points lower at AER than in Q2 2019 and 
  5.4 percentage points lower on a CER basis. This primarily reflected 
  the negative operating leverage from the COVID-19 related sales decline, 
  a significant increase in Oncology R&D and initiation of several 
  COVID-19 programmes, increase in cost of sales percentage due to 
  the continued impact of lower prices, particularly in Respiratory, 
  and investment in new product support and targeted priority markets. 
  This was partly offset by reduced promotional and variable spending 
  as a result of the COVID-19 lockdowns and tight control of ongoing 
  costs. 
  Vaccines operating profit was GBP265 million, down 57% AER, 58% CER 
  on a turnover decrease of 29% CER. The operating margin of 23.4% 
  was 15.2 percentage points lower at AER than in Q2 2019 and 15.7 
  percentage points lower on a CER basis. This was primarily driven 
  by the negative operating leverage from the significant COVID-19-related 
  sales decline, as well as adverse mix and an adverse comparison to 
  income from one-off settlements in Q2 2019, partly offset by lower 
  inventory adjustments. 
 
  Consumer Healthcare operating profit was GBP521 million, up 33% AER, 
  33% CER on a turnover increase of 25% CER. On a pro-forma basis, 
  operating profit was GBP521 million, 11% CER lower on a turnover 
  decrease of 6% CER. The operating margin of 21.8% was 1.4 percentage 
  points higher at AER and 1.3 percentage points higher on a CER basis 
  than in Q2 2019. The pro-forma operating margin of 21.8% was 1.2 
  percentage points lower on a CER basis. This was primarily driven 
  by reduced leverage from a decline in sales growth in the quarter 
  due to COVID-19 customer destocking and lower customer footfall. 
  This decline was partly offset by synergy benefits from the Pfizer 
  integration and targeted areas of lower promotional investment. 
 
  Net finance costs 
  Total net finance costs were GBP228 million compared with GBP216 
  million in Q2 2019. Adjusted net finance costs were GBP227 million 
  compared with GBP220 million in Q2 2019. The increase primarily reflected 
  reduced swap interest income on foreign currency hedges and lower 
  interest income on reduced overseas cash following the divestment 
  of Horlicks and other Consumer Healthcare nutrition products in India 
  and a number of other countries. The increase was partly offset by 
  favourable refinancing of term debt. 
  Share of after tax profits of associates and joint ventures 
  The share of after tax profits of associates and joint ventures was 
  GBP19 million (Q2 2019: GBP4 million losses). 
  Taxation 
  The charge of GBP201 million represented an effective tax rate on 
  Total results of 7.6% (Q2 2019: 16.9%) and reflected the different 
  tax effects of the various Adjusting items, including the disposal 
  of Horlicks and other Consumer Healthcare brands to Unilever and 
  the subsequent disposal of shares received in Hindustan Unilever. 
  Tax on Adjusted profit amounted to GBP316 million and represented 
  an effective Adjusted tax rate of 20.5% (Q2 2019: 15.4%), reflecting 
  delays in settlement of open periods and an updated forecast profit 
  mix for the year. 
 
  Issues related to taxation are described in Note 14, 'Taxation' in 
  the Annual Report 2019. The Group continues to believe it has made 
  adequate provision for the liabilities likely to arise from periods 
  which are open and not yet agreed by tax authorities. The ultimate 
  liability for such matters may vary from the amounts provided and 
  is dependent upon the outcome of agreements with relevant tax authorities. 
  Non-controlling interests 
  The allocation of Total earnings to non-controlling interests amounted 
  to GBP177 million (Q2 2019: GBP86 million). The increase was primarily 
  due to the allocation of Consumer Healthcare profits of GBP137 million 
  (Q2 2019: GBPnil) following the completion of the new Consumer Healthcare 
  Joint Venture with Pfizer on 31 July 2019, partly offset by reduced 
  allocation of ViiV Healthcare profits of GBP24 million (Q2 2019: 
  GBP75 million), including increased charges for re-measurement of 
  contingent consideration liabilities. 
  The allocation of Adjusted earnings to non-controlling interests 
  amounted to GBP267 million (Q2 2019: GBP138 million). The increase 
  in allocation primarily reflected an increased allocation of Consumer 
  Healthcare profits of GBP138 million (Q2 2019: GBPnil) following 
  the completion of the new Consumer Healthcare Joint Venture with 
  Pfizer on 31 July 2019 partly offset by a reduced allocation of ViiV 
  Healthcare profits of GBP113 million (Q2 2019: GBP127 million). 
  Earnings per share 
  Total EPS was 45.5p, compared with 19.5p in Q2 2019. The increase 
  in EPS primarily reflected the net profit on disposal of Horlicks 
  and other Consumer Healthcare brands as well as increased income 
  from asset disposals, partly offset by higher re-measurement charges 
  on the contingent consideration liabilities and lower operating performance 
  as a result of the COVID-19 impact on the Vaccines business and destocking 
  in Pharmaceuticals and Consumer Healthcare following a strong operating 
  performance in Q1 2020. 
  Adjusted EPS was 19.2p compared with 30.5p in Q2 2019, down 37% AER, 
  38% CER, on a 21% CER decrease in Adjusted operating profit. This 
  reduction primarily resulted from a higher effective tax rate and 
  a higher non-controlling interest allocation of Consumer Healthcare 
  profits. 
  Currency impact on Q2 2020 results 
  The results for Q2 2020 are based on average exchange rates, principally 
  GBP1/$1.25, GBP1/EUR1.13 and GBP1/Yen 134. Comparative exchange rates 
  are given on page 59. The period-end exchange rates were GBP1/$1.23, 
  GBP1/EUR1.10 and GBP1/Yen 132. 
  In the quarter, turnover decreased 2% AER, 3% CER. Total EPS was 
  45.5p compared with 19.5p in Q2 2019. Adjusted EPS was 19.2p compared 
  with 30.5p in Q2 2019, down 37% AER, 38% CER. The marginally positive 
  currency impact primarily reflected the weakness in Sterling, particularly 
  against the US$ and Yen, partly offset by weakness in emerging market 
  currencies relative to Q2 2019. Exchange gains or losses on the settlement 
  of intercompany transactions had a negligible impact on the positive 
  currency impact of one percentage point on Adjusted EPS.

  Q2 2020 and Q2 2019 are set out below.

 Major restructuring and integration 
  Within the Pharmaceuticals sector, the highly regulated manufacturing 
  operations and supply chains and long lifecycle of the business mean 
  that restructuring programmes, particularly those that involve the 
  rationalisation or closure of manufacturing or R&D sites are likely 
  to take several years to complete. 
 
 
 Total Major restructuring charges incurred in Q2 2020 were GBP193 
  million (Q2 2019: GBP309 million), analysed as follows:

 Cash charges primarily arose from restructuring of Vaccines Manufacturing 
  and R&D functions as well as commercial pharmaceuticals restructuring 
  under the Separation Preparation programme, integration costs under 
  the Consumer Healthcare Joint Venture integration programme and restructuring 
  of the manufacturing organisation, R&D and some administrative functions 
  as well as the integration of Tesaro under the 2018 major restructuring 
  programme. Non-cash charges under the 2018 major restructuring programme 
  primarily related to write down of sites on disposal of sites as 
  part of plans to restructure the manufacturing network. 
  Total cash payments made in Q2 2020 were GBP163 million (Q2 2019: 
  GBP111 million), GBP31 million for the existing Combined restructuring 
  and integration programme (Q2 2019: GBP63 million), GBP47 million 
  (Q2 2019: GBP28 million) under the 2018 major restructuring programme 
  including the settlement of certain charges accrued in previous quarters, 
  a further GBP65 million (Q2 2019: GBP20 million) relating to the 
  Consumer Healthcare Joint Venture integration programme and GBP20 
  million relating to the Separation Preparation restructuring programme.

 The benefit in the quarter from the 2018 major restructuring programme 
  was GBP0.1 billion and the benefit from the Consumer Healthcare Joint 
  Venture integration was GBP0.1 billion. Given its early stage the 
  benefit from the Separation Preparation restructuring programme was 
  less than GBP0.1 billion. 
 
 
 Transaction-related adjustments 
  Transaction-related adjustments resulted in a net charge of GBP349 
  million (Q2 2019: GBP247 million). This included a net GBP368 million 
  accounting charge for the re-measurement of the contingent consideration 
  liabilities related to the acquisitions of the former Shionogi-ViiV 
  Healthcare joint venture and the former Novartis Vaccines business 
  and the liabilities for the Pfizer put option and Pfizer and Shionogi 
  preferential dividends in ViiV Healthcare.

 The GBP343 million charge relating to the contingent consideration 
  for the former Shionogi-ViiV Healthcare joint venture represented 
  an increase in the valuation of the contingent consideration due 
  to Shionogi, primarily as a result of a GBP99 million unwind of the 
  discount and a GBP244 million charge primarily from adjustments to 
  sales forecasts as well as updated exchange rate assumptions. 
  The ViiV Healthcare contingent consideration liability is valued 
  on a long-term basis. The potential impact of the COVID-19 pandemic 
  remains uncertain and at 30 June 2020, it has been assumed that there 
  will be no significant impact on the long-term value of the liability. 
  This position remains under review and the amount of the liability 
  will be updated in future quarters as further information on the 
  impact of the pandemic becomes available. An explanation of the accounting 
  for the non-controlling interests in ViiV Healthcare is set out on 
  page 11. 
  Divestments, significant legal charges and other items 
  Divestments and other items included a gain in the period of GBP1,828 
  million arising from the net profit on disposal in the quarter of 
  the Horlicks and other Consumer Healthcare brands of GBP2,304 million 
  in Q2 2020, partly offset by the related loss on sale of the shares 
  in Hindustan Unilever in Q2 2020 of GBP476 million. The net profit 
  on disposal in the quarter was net of reversal of GBP776 million 
  of embedded derivative gains on the value of the shares taken in 
  prior years and Q1 2020. Divestments and other items also included 
  a gain from a number of asset disposals and certain other Adjusting 
  items. A charge of GBP1 million (Q2 2019: GBP47 million) for significant 
  legal matters included the settlement of existing matters as well 
  as provisions for ongoing litigation. Significant legal cash payments 
  were GBP1 million (Q2 2019: GBP4 million). 
  Separation costs 
  From Q2 2020, the Group has started to report additional one-time 
  costs to prepare for Consumer Healthcare separation.

 Pharmaceuticals turnover in the six months was GBP8,498 million, 
  flat at both AER and CER. HIV sales were up 3% AER, 2% CER, to GBP2,392 
  million, with growth in Juluca and Dovato partly offset by Tivicay 
  and Triumeq. Respiratory sales were up 27% AER, 26% CER, to GBP1,754 
  million, on growth of Trelegy and Nucala. Sales of Established Pharmaceuticals 
  declined 12% AER, 11% CER to GBP3,866 million. 
  Towards the end of the first quarter, additional demand related to 
  the COVID-19 pandemic had a positive impact on growth of HIV and 
  Respiratory products. As expected, this effect has broadly reversed 
  in the second quarter, with only a minor dolutegravir impact in Europe 
  and US remaining. The second quarter also saw lower levels of new 
  patient prescriptions in the US and Europe, reduced market demand 
  for allergy and antibiotic products in International and pressure 
  on net prices in the US. 
  In the US, sales grew 3% AER, 1% CER. Continued growth of Nucala, 
  Trelegy, Benlysta and the HIV two-drug regimens was partly offset 
  by the decline and COVID-19 destocking in Tivicay, Triumeq and Established 
  Products, including the impact of generic albuterol substitutes. 
  In Europe, sales grew 2% AER, 2% CER, with strong growth from Respiratory, 
  HIV, Oncology and Benlysta partly offset by the decline of Established 
  Pharmaceutical sales, with the net impact of COVID-19 broadly neutral 
  over the six months. 
  International declined 3% AER, 2% CER, with Respiratory, HIV and 
  Benlysta growth more than offset by lower Established Pharmaceutical 
  sales including the impact of a weaker allergy season in Japan and 
  lower sales in China including the impact of government mandated 
  changes increasing the use of generics. 
  Respiratory 
  Total Respiratory sales were up 27% AER, 26% CER, with strong growth 
  in all regions. International Respiratory sales grew 26% AER, 26% 
  CER including Nucala, up 46% AER, 42% CER, and Relvar/Breo, up 13% 
  AER, 14% CER to GBP164 million. In Europe, Respiratory sales were 
  GBP466 million up 26% AER, 27% CER. In the US, Trelegy and Nucala 
  growth continued and Relvar/Breo benefited from the impact of a prior 
  period RAR adjustment in the first quarter. 
  Sales of Nucala were GBP451 million in the six months and grew 30% 
  AER, 28% CER, with US sales up 31% AER, 29% CER to GBP265 million. 
  Europe sales of GBP116 million grew 20% AER, 21% CER and International 
  sales of GBP70 million grew 46% AER, 42% CER including growth of 
  the at-home use application. 
  Trelegy sales were up 87% AER, 85% CER to GBP387 million driven by 
  growth in all regions. In the US, sales grew 81% AER, 77% CER, reflecting 
  continued market share growth. In Europe, sales grew 90% AER, 90% 
  CER and in International sales were GBP35 million in the six months. 
  Relvar/Breo sales were up 16% AER, 16% CER to GBP527 million in the 
  six months. In the US, Relvar/Breo grew 16% AER, 14% CER, benefiting 
  from the impact of a prior period RAR adjustment in the first quarter. 
  In Europe and International, Relvar/Breo also continued to grow, 
  up 20% AER, 20% CER and 13% AER, 14% CER respectively. 
  HIV 
  HIV sales were GBP2,392 million up 3% AER, 2% CER in the six months. 
  The dolutegravir franchise grew 4% AER, 3% CER, delivering sales 
  of GBP2,301 million. The remaining portfolio, with sales of GBP91 
  million and 4% of total HIV sales, declined 22% AER, 23% CER and 
  reduced the overall growth of total HIV by one percentage point. 
  Sales of dolutegravir products were GBP2,301 million in the six months. 
  Sales benefited from customer stock building due to COVID-19, mainly 
  on Tivicay and Triumeq that has not yet fully reversed. Tivicay delivered 
  sales of GBP785 million, down 1% AER, 2% CER and Triumeq sales were 
  GBP1,149 million, down 9% AER, 10% CER. The two-drug regimens, Juluca 
  and Dovato delivered sales of GBP367 million in the six months, with 
  combined growth more than offsetting decline in the three-drug regimen, 
  Triumeq. 
  In the US, dolutegravir sales grew 2% AER, but were flat at CER, 
  and in Europe sales grew 6% AER, 6% CER. The growth was driven by 
  two-drug regimen share growth and benefited from customer stocking 
  due to COVID-19 not fully reversed in the six months. Following recent 
  launches of Dovato, combined sales of the two-drug regimens were 
  GBP278 million in the US and GBP81 million in Europe, with growth 
  offsetting the decline in Triumeq. International continued to grow 
  strongly with total dolutegravir sales growth of 10% AER, 14% CER, 
  driven by Tivicay tender business. 
  Oncology 
  Sales of Zejula, the PARP inhibitor asset acquired from Tesaro in 
  Q1 2019 were GBP158 million in the six months, up 60% AER, 58% CER 
  benefiting from a favourable comparison with H1 2019. Sales comprised 
  GBP95 million in the US and GBP63 million in Europe. 
  Immuno-inflammation 
  Sales of Benlysta in the six months were up 21% AER, 19% CER to GBP328 
  million, including sales of the sub-cutaneous formulation of GBP156 
  million. In the US, Benlysta grew 18% AER, 16% CER to GBP279 million. 
  Established Pharmaceuticals 
  Sales of Established Pharmaceuticals in the six months were GBP3,866 
  million, down 12% AER, 11% CER. 
  Established Respiratory products declined 11% AER, 11% CER to GBP1,770 
  million. Advair/Seretide and Ventolin were impacted by generic substitutes 
  in the US and Europe, and in the International region allergy sales 
  were impacted by market contraction in Japan. 
  The remainder of the Established Pharmaceuticals portfolio declined 
  12% AER, 11% CER to GBP2,096 million, including the impact of lower 
  demand for antibiotics and Dermatology products during the COVID-19 
  pandemic period, the impact of government mandated changes increasing 
  the use of generics in China, and a strong comparator, including 
  the European Relenza contract.

 Vaccines turnover declined 5% AER, 6% CER to GBP2,938 million, primarily 
  driven by the adverse impact of the COVID-19 pandemic on Hepatitis, 
  DTPa-containing, Meningitis and Shingles vaccines, partially offset 
  by growth in Shingrix in Q1 2020. 
 
  Vaccines performance across all regions was affected by lower demand 
  due to limited visits to healthcare practitioners and points of vaccination 
  during the pandemic and government stay-at-home directives. In areas 
  where lockdowns were lifted, wellness visits and vaccination rates 
  have started to recover, with paediatric vaccination near pre-COVID 
  levels by the end of the period, while adolescent and adult immunisations 
  improved at a slower pace. 
 
  Meningitis 
  Meningitis sales declined 12% AER, 10% CER to GBP392 million. Bexsero 
  sales declined 13% AER, 11% CER to GBP272 million, reflecting lower 
  demand across all regions due to the COVID-19 pandemic. Menveo sales 
  declined 18% AER, 17% CER to GBP78 million, primarily driven by the 
  negative impact of COVID-19 lockdowns on vaccination rates partly 
  offset by higher demand in Europe. In the US, Bexsero and Menveo 
  grew market share. 
 
  Influenza 
  Fluarix/FluLaval sales were GBP36 million, up 13% AER, 22% CER, 
  reflecting favourable phasing and higher demand in the International 
  region. 
 
  Shingles 
  Shingrix sales grew 31% AER, 28% CER to GBP970 million, primarily 
  driven by strong uptake in Q1 2020 and favourable returns and rebates, 
  partly offset by a decline in demand in Q2 2020 due to lower adult 
  wellness visits and vaccination rates related to COVID-19 pandemic 
  stay-at-home directives in the US. In Europe, a strong performance 
  was recorded in Germany due to robust underlying demand in post-lockdown 
  conditions 
 
  Established Vaccines 
  Sales of DTPa-containing vaccines (Infanrix, Pediarix and Boostrix) 
  declined by 24% AER, 25% CER. Infanrix/Pediarix sales declined 21% 
  AER, 21% CER to GBP299 million, reflecting lower demand due to the 
  COVID-19 pandemic in the US, unfavourable year-on-year US CDC stockpile 
  movements and supply constraints in Europe. 
 
  Hepatitis vaccines declined 35% AER, 36% CER to GBP299 million, impacted 
  in the US and Europe by the COVID-19 pandemic and related travel 
  restrictions, together with competition returning to market in the 
  US. 
 
  Synflorix sales were GBP226 million, down 1% AER, but flat at CER, 
  primarily due to lower tender volume demand in Europe partly offset 
  by higher demand in International. 
 
  Rotarix sales were up 12% AER, 12% CER to GBP279 million, reflecting 
  favourable phasing in Emerging Markets and in International, partly 
  offset by lower demand in the US due to COVID-19 confinement measures. 
 
  MMRV vaccines sales grew 6% AER, 8% CER to GBP111 million, largely 
  driven by improved supply in Europe.

 On a reported basis, sales grew 35% AER, 36% CER to GBP5,251 million 
  in the six months, largely driven by the inclusion of the Pfizer 
  portfolio. On a pro-forma basis, sales grew 2% CER, and 7% CER excluding 
  brands divested/under review. This reflected the strong performance 
  in the first quarter, continued strong demand of Vitamins, minerals 
  and supplements products and increased retailer stocking ahead of 
  a systems cutover in North America which benefited sales by one percentage 
  point in the six months. The remaining small stocking benefit from 
  COVID-19 is expected to fully unwind in the second half of the year, 
  and the sales cutover benefit to reverse in the third quarter. 
 
  Oral health 
  Oral health sales grew 4% AER, 6% CER to GBP1,372 million. Sensodyne 
  continued to perform strongly, reporting low double-digit growth, 
  reflecting underlying strength of the brand, supported by recent 
  innovations including Sensodyne Sensitivity & Gum. Gum health grew 
  in double digits, while Denture care was flat. Growth in Oral health 
  was impacted by a decline in the non-strategic brands. 
 
  Pain relief 
  Pain relief grew 51% AER, 53% CER to GBP1,140 million. On a pro-forma 
  basis, sales grew in mid-single digits, with significant growth of 
  Panadol and Advil reflecting accelerated purchases and increased 
  consumption due to the COVID-19 pandemic, particularly in Q1 2020. 
  The successful launch of Voltaren OTC in the US contributed to overall 
  growth for the brand, although performance was impacted by a weaker 
  performance in Europe. 
 
  Vitamins, minerals and supplements 
  Vitamins, minerals and supplements growth more than doubled to GBP767 
  million. On a pro-forma basis, sales grew in the high teens per cent, 
  with strong performance from Centrum and Emergen-C driven by increased 
  consumer demand for the category, particularly in the US and China. 
 
  Respiratory health 
  Respiratory health sales grew 34% AER, 34% CER to GBP653 million. 
  On a pro-forma basis, sales grew in low double-digits, with broad-based 
  growth across the category, although the accelerated purchases and 
  increased consumption in response to the COVID-19 pandemic seen in 
  the first quarter largely unwound in the second quarter. 
 
  Digestive health and other 
  Digestive health and other brands grew 26% AER, 26% CER to GBP939 
  million. On a pro-forma basis, sales declined in low single-digits, 
  with growth in Smokers' health and Digestive health products offset 
  by a low double digit decline in Skin health products and a decline 
  in other non-strategic brands. 
 
 
 Operating performance 
 
 
 Cost of sales 
  Total cost of sales as a percentage of turnover was 33.8%, 0.9 percentage 
  points lower at AER and 0.8 percentage points lower in CER terms 
  compared with H1 2019. This reflected a reduction in the costs of 
  Major restructuring programmes, primarily as a result of lower write 
  downs in a number of manufacturing sites, partly offset by the unwinding 
  of the fair market value uplift on inventory arising on completion 
  of the Consumer Healthcare Joint Venture with Pfizer. 
  Excluding these and other Adjusting items, Adjusted cost of sales 
  as a percentage of turnover was 29.1%, 0.3 percentage points higher 
  at AER, 0.5 percentage points higher at CER compared with H1 2019. 
  On a pro-forma basis, Adjusted cost of sales as a percentage of turnover 
  was 29.1%, 0.1 percentage points higher at CER, compared with H1 
  2019. This reflected continued adverse pricing pressure in Pharmaceuticals, 
  particularly in Respiratory and unfavourable product mix in Consumer 
  Healthcare, partly offset by a more favourable product mix in Vaccines, 
  and a further contribution from integration savings in Consumer Healthcare. 
  Selling, general and administration 
  Total SG&A costs as a percentage of turnover were 33.7%, 0.9 percentage 
  points higher at AER and 1.1 percentage points higher at CER compared 
  with H1 2019. This reflected increased Major restructuring costs 
  partly offset by lower significant legal and transaction costs. 
  Excluding these and other Adjusting items, Adjusted SG&A costs as 
  a percentage of turnover were 31.8%, 0.6 percentage points higher 
  at AER than in H1 2019 and 0.8 percentage points higher on a CER 
  basis. On a pro-forma basis, Adjusted SG&A costs as a percentage 
  of turnover were 31.8%, 0.5 percentage points higher at CER, compared 
  with H1 2019. 
  The growth in Adjusted SG&A costs of 10% AER, 11% CER and 1% CER 
  on a pro-forma basis reflected increased investment resulting from 
  the acquisition of Tesaro and in promotional product support, particularly 
  for new launches in Vaccines, Respiratory and HIV as well as increased 
  costs for a number of legal settlements. This was partly offset by 
  reduced promotional and variable spending across all three business 
  as a result of the COVID-19 lockdowns, the continuing benefit of 
  restructuring in Pharmaceuticals and Consumer Healthcare and the 
  tight control of ongoing costs, particularly in non-promotional spending 
  across all three businesses. 
  Research and development 
  Total R&D expenditure was GBP2,488 million (14.9% of turnover), up 
  17% AER, 16% CER, including an increase in Major restructuring costs. 
  Adjusted R&D expenditure was GBP2,257 million (13.5% of turnover), 
  12% higher at AER, 11% higher at CER than in H1 2019. On a pro-forma 
  basis, Adjusted R&D expenditure grew 9% CER compared with H1 2019. 
  Pharmaceuticals R&D expenditure was GBP1,775 million, up 15% AER, 
  13% CER, primarily driven by a continued significant increase in 
  investment in Oncology reflecting the assets from the Tesaro acquisition 
  (primarily Zejula and dostarlimab) and progression of a number of 
  other programmes including belantamab mafodotin, ICOS and bintrafusp 
  alfa as well as the initiation of several programmes focused on COVID-19. 
  This increased investment has been partly offset by a reduction in 
  investment in Research due to the early phase portfolio reprioritisation 
  in 2019. R&D expenditure in Vaccines and Consumer Healthcare was 
  GBP333 million and GBP149 million, respectively. 
  Royalty income 
  Royalty income was GBP142 million (H1 2019: GBP151 million), down 
  6% AER, 8% CER, primarily reflecting adverse movements in Consumer 
  Healthcare. 
 
 
 Other operating income/(expense) 
  Net other operating income of GBP1,769 million (H1 2019: GBP153 million 
  expense) primarily reflected the net profit on disposal of the Horlicks 
  and other Consumer Healthcare brands of GBP2,815 million in Q2 2020, 
  which was after reversal of GBP240 million of embedded derivative 
  gains on the value of the shares taken in prior years. This was partly 
  offset by the related loss on sale of the shares in Hindustan Unilever 
  in Q2 2020 of GBP476 million. Other operating income also included 
  an increase in profit and milestone income from a number of asset 
  disposals. 
  This was partly offset by accounting charges of GBP841 million (H1 
  2019: GBP103 million) arising from the re-measurement of the contingent 
  consideration liabilities related to the acquisitions of the former 
  Shionogi-ViiV Healthcare joint venture and the former Novartis Vaccines 
  business and the liabilities for the Pfizer put option and Pfizer 
  and Shionogi preferential dividends in ViiV Healthcare. This included 
  a re-measurement charge of GBP778 million (H1 2019: GBP166 million) 
  for the contingent consideration liability due to Shionogi, primarily 
  arising from changes in exchange rate assumptions as well as sales 
  forecasts and the unwind of the discounting. 
 
 
 Operating profit 
  Total operating profit was GBP4,864 million in H1 2020 compared with 
  GBP2,912 million in H1 2019. This reflected the profit on disposal 
  of the Horlicks and other Consumer Healthcare brands and resultant 
  sale of shares in Hindustan Unilever as well as increased income 
  from asset disposals. This was partly offset by higher re-measurement 
  charges on the contingent consideration liabilities. 
  Excluding these and other Adjusting items, Adjusted operating profit 
  was GBP4,424 million, 2% higher than H1 2019 at AER and 2% higher 
  at CER on a turnover increase of 8% CER. The Adjusted operating margin 
  of 26.5% was 1.5 percentage points lower at AER, and 1.7 percentage 
  points lower on a CER basis than in H1 2019. On a pro-forma basis, 
  Adjusted operating profit was 7% lower at CER on a turnover which 
  was flat at CER. The Adjusted pro-forma operating margin of 26.5% 
  was 1.9 percentage points lower on a CER basis than in H1 2019. 
  The reduction in pro-forma Adjusted operating profit primarily reflected 
  the adverse impact from the reduction in sales in Vaccines as a result 
  of the COVID-19 pandemic, investment in R&D including a significant 
  increase in Oncology investment, partly on the assets from the Tesaro 
  acquisition and initiation of several COVID-19 programmes, continuing 
  price pressure, particularly in Respiratory, including the impact 
  of the launch of a generic version of Advair in the US in February 
  2019 and investments in promotional product support, particularly 
  for new launches in Vaccines, HIV and Respiratory. This was partly 
  offset by a favourable mix in Vaccines, reduced promotional and variable 
  spending across all three business as a result of the COVID-19 lockdowns, 
  the continuing benefit of restructuring in Pharmaceuticals and Consumer 
  Healthcare and the tight control of ongoing costs, particularly in 
  non-promotional spending across all three businesses. 
  Contingent consideration cash payments which are made to Shionogi 
  and other companies reduce the balance sheet liability and hence 
  are not recorded in the income statement. Total contingent consideration 
  cash payments in H1 2020 amounted to GBP455 million (H1 2019: GBP443 
  million). This included cash payments made to Shionogi of GBP445 
  million (H1 2019: GBP439 million). 
  Operating profit by business 
  Pharmaceuticals operating profit was GBP2,159 million, down 13% AER, 
  14% CER on turnover that was flat at CER. The operating margin of 
  25.4% was 4.1 percentage points lower at AER than in H1 2019 and 
  4.2 percentage points lower on a CER basis. This primarily reflected 
  a significant increase in Oncology R&D, the increase in cost of sales 
  percentage due to the continued impact of lower prices, particularly 
  in Respiratory, including the impact of the launch of a generic version 
  of Advair in the US in February 2019, and investment in new product 
  support and targeted priority markets, together with higher provisions 
  for legal settlements and costs in the six months. This was partly 
  offset by the reduced promotional and variable spending as a result 
  of the COVID-19 lockdowns, the continued benefit of restructuring 
  and tight control of ongoing costs. 
  Vaccines operating profit was GBP1,123 million, down 8% AER, 10% 
  CER on a turnover decrease of 6% CER. The operating margin of 38.2% 
  was 1.2 percentage points lower at AER than in H1 2019 and 1.6 percentage 
  points lower on a CER basis. This was primarily driven by negative 
  operating leverage from the COVID-19 related decline in sales, investment 
  behind key brands and income from one-off settlements in 2019, partly 
  offset by positive product mix. 
 
  Consumer Healthcare operating profit was GBP1,287 million, up 57% 
  AER, 59% CER on a turnover increase of 36% CER. On a pro-forma basis, 
  operating profit was GBP1,287 million, 8% CER higher on a turnover 
  increase of 2% CER. The operating margin of 24.5% was 3.4 percentage 
  points higher at AER and 3.5 percentage points higher on a CER basis 
  than in Q2 2019. The pro-forma operating margin of 24.5% was 1.2 
  percentage points higher on a CER basis. The higher margin was driven 
  by higher than normal sales growth in Q1 2020, partly offset by a 
  decline and unwind in Q2 2020, primarily due to COVID-19 buying patterns. 
  Margin growth was also supported by synergy delivery from the Pfizer 
  integration and targeted areas of lower promotional investment due 
  to lockdown impacts. 
 
  Net finance costs 
  Total net finance costs were GBP416 million compared with GBP406 
  million in H1 2019. Adjusted net finance costs were GBP414 million 
  compared with GBP407 million in H1 2019. The increase primarily reflected 
  reduced interest income on overseas cash following the divestment 
  of Horlicks and other Consumer Healthcare nutrition products in India 
  and a number of other countries plus reduced swap interest income 
  on foreign currency hedges. The increase was partly offset by favourable 
  refinancing of term debt. 
  Share of after tax profits of associates and joint ventures 
  The share of after tax profits of associates was GBP28 million (H1 
  2019: GBP53 million). H1 2019 included a one-off adjustment of GBP51 
  million to reflect GSK's share of increased after tax profits of 
  Innoviva primarily as a result of a non-recurring income tax benefit. 
  Taxation 
  The charge of GBP357 million represented an effective tax rate on 
  Total results of 8.0% (H1 2019: 20.5%) and reflected the different 
  tax effects of the various Adjusting items, including the disposal 
  of Horlicks and other Consumer Healthcare brands to Unilever and 
  subsequent disposal of shares received in Hindustan Unilever. Tax 
  on Adjusted profit amounted to GBP658 million and represented an 
  effective Adjusted tax rate of 16.3% (H1 2019: 17.6%), reflecting 
  cancellation by the UK Government of a reduction in the UK corporation 
  tax rate from 19% to 17% resulting in an increase in the value of 
  balance sheet deferred tax assets. 
  Issues related to taxation are described in Note 14, 'Taxation' in 
  the Annual Report 2019. The Group continues to believe it has made 
  adequate provision for the liabilities likely to arise from periods 
  which are open and not yet agreed by tax authorities. The ultimate 
  liability for such matters may vary from the amounts provided and 
  is dependent upon the outcome of agreements with relevant tax authorities. 
  Non-controlling interests 
  The allocation of Total earnings to non-controlling interests amounted 
  to GBP291 million (H1 2019: GBP241 million). The increase was primarily 
  due to an increased allocation of Consumer Healthcare profits of 
  GBP196 million (H1 2019: GBPnil) following the completion of the 
  new Consumer Healthcare Joint Venture with Pfizer on 31 July 2019, 
  and which included the unwind of the fair value uplift on acquired 
  inventory and major restructuring costs. This was partly offset by 
  a reduced allocation of ViiV Healthcare profits of GBP64 million 
  (H1 2019: GBP204 million), including increased charges for re-measurement 
  of contingent consideration liabilities. 
  The allocation of Adjusted earnings to non-controlling interests 
  amounted to GBP549 million (H1 2019: GBP287 million). The increase 
  in allocation primarily reflected an increased allocation of Consumer 
  Healthcare profits of GBP277 million (H1 2019: GBPnil) following 
  the completion of the new Consumer Healthcare Joint Venture with 
  Pfizer on 31 July 2019 partly offset by a reduced allocation of ViiV 
  Healthcare profits of GBP241 million (H1 2019: GBP250 million), and 
  lower net profits in some of the Group's other entities with non-controlling 
  interests, primarily Consumer Healthcare India following the Horlicks 
  and other Consumer brands disposal. 
  Earnings per share 
  Total EPS was 77.0p, compared with 36.3p in H1 2019. The increase 
  in EPS primarily reflected the net profit on disposal of Horlicks 
  and other Consumer Healthcare brands as well as increased income 
  from asset disposals, partly offset by higher re-measurement charges 
  on the contingent consideration liabilities and a one-off benefit 
  in H1 2019 from increased share of after tax profits of the associate 
  Innoviva. 
  Adjusted EPS was 56.9p compared with 60.6p in H1 2019, down 6% AER, 
  6% CER, on a 2% CER increase in Adjusted operating profit. The reduction 
  primarily resulted from a higher non-controlling interest allocation 
  of Consumer Healthcare profits, reduced share of after tax profits 
  of associates resulting from a non-recurring income tax benefit in 
  Innoviva and partly offset by a reduced effective tax rate. 
  Currency impact on H1 2020 results 
  The results for H1 2020 are based on average exchange rates, principally 
  GBP1/$1.27, GBP1/EUR1.15 and GBP1/Yen 137. Comparative exchange rates 
  are given on page 59. The period-end exchange rates were GBP1/$1.23, 
  GBP1/EUR1.10 and GBP1/Yen 132. 
  In the six months, turnover increased 8% AER, 8% CER. Total EPS was 
  77.0p compared with 36.3p in H1 2019. Adjusted EPS was 56.9p compared 
  with 60.6p in H1 2019, down 6% AER, 6% CER. The flat currency impact 
  primarily reflected the weakness of Sterling, particularly against 
  the US$ and Yen, offset by weakness in emerging market currencies 
  relative to H1 2019. Exchange gains or losses on the settlement of 
  intercompany transactions had a negligible impact on the flat currency 
  impact on Adjusted EPS.

 Major restructuring and integration 
  Within the Pharmaceuticals sector, the highly regulated manufacturing 
  operations and supply chains and long lifecycle of the business mean 
  that restructuring programmes, particularly those that involve the 
  rationalisation or closure of manufacturing or R&D sites are likely 
  to take several years to complete. 
 
 
 Total Major restructuring charges incurred in H1 2020 were GBP676 
  million (H1 2019: GBP689 million), analysed as follows:

 Cash charges primarily arose from restructuring of Vaccines Manufacturing 
  and R&D functions as well as commercial pharmaceuticals and some 
  administrative functions restructuring under the Separation Preparation 
  programme, integration costs under the Consumer Healthcare Joint 
  Venture integration programme and restructuring of the manufacturing 
  organisation, R&D and some administrative functions as well as the 
  integration of Tesaro under the 2018 major restructuring programme. 
  Non-cash charges under the 2018 major restructuring programme primarily 
  related to write down of sites on disposal of sites as part of plans 
  to restructure the manufacturing network. 
  Total cash payments made in H1 2020 were GBP331 million (H1 2019: 
  GBP285 million), GBP65 million for the existing Combined restructuring 
  and integration programme (H1 2019: GBP219 million), GBP100 million 
  (H1 2019: GBP46 million) under the 2018 major restructuring programme 
  including the settlement of certain charges accrued in previous quarters, 
  a further GBP135 million (H1 2019: GBP20 million) relating to the 
  Consumer Healthcare Joint Venture integration programme and GBP31 
  million relating to the Separation Preparation restructuring programme.

 The benefit in the six months from the 2018 major restructuring programme 
  was GBP0.2 billion and the benefit from the Consumer Healthcare Joint 
  Venture integration was GBP0.1 billion. Given its early stage the 
  benefit from the Separation Preparation restructuring programme was 
  less than GBP0.1 billion. 
  The 2018 major restructuring programme, including Tesaro, is expected 
  to cost GBP1.75 billion over the period to 2021, with cash costs 
  of GBP0.85 billion and non-cash costs of GBP0.9 billion, and is expected 
  to deliver annual savings of around GBP450 million by 2021 (at 2019 
  rates). These savings are intended to be fully re-invested to help 
  fund targeted increases in R&D and commercial support of new products. 
 
  The completion of the new Consumer Healthcare Joint Venture with 
  Pfizer is expected to realise substantial cost synergies, generating 
  total annual cost savings of GBP0.5 billion by 2022 for expected 
  cash costs of GBP0.7 billion and non-cash charges of GBP0.3 billion, 
  plus additional capital expenditure of GBP0.2 billion. Up to 25% 
  of the cost savings are intended to be reinvested in the business 
  to support innovation and other growth opportunities. 
 
  The Group initiated in Q1 2020 a two-year Separation Preparation 
  programme to prepare for the separation of GSK into two companies: 
  New GSK, a biopharma company with an R&D approach focused on science 
  related to the immune system, the use of genetics and new technologies, 
  and a new leader in Consumer Healthcare. The programme aims to: 
 
 
 --   Drive a common approach to R&D with improved capital allocation 
 --   Align and improve the capabilities and efficiency of global support 
       functions to support New GSK 
 --   Further optimise the supply chain and product portfolio, including 
       the divestment of non-core assets. A strategic review of prescription 
       dermatology is underway 
 --   Prepare Consumer Healthcare to operate as a standalone company 
 
 
 The programme will target delivery of GBP0.7 billion of annual savings 
  by 2022 and GBP0.8 billion by 2023, with total costs estimated at 
  GBP2.4 billion, of which GBP1.6 billion is expected to be cash costs. 
  The proceeds of anticipated divestments are largely expected to cover 
  the cash costs of the programme. 
 
 
 Transaction-related adjustments 
  Transaction-related adjustments resulted in a net charge of GBP918 
  million (H1 2019: GBP194 million). This included a net GBP841 million 
  accounting charge for the re-measurement of the contingent consideration 
  liabilities related to the acquisitions of the former Shionogi-ViiV 
  Healthcare joint venture and the former Novartis Vaccines business 
  and the liabilities for the Pfizer put option and Pfizer and Shionogi 
  preferential dividends in ViiV Healthcare.

 The GBP778 million charge relating to the contingent consideration 
  for the former Shionogi-ViiV Healthcare joint venture represented 
  an increase in the valuation of the contingent consideration due 
  to Shionogi, as a result of a GBP193 million unwind of the discount 
  and GBP585 million primarily from updated exchange rate assumptions 
  as well as adjustments to sales forecasts. The GBP59 million charge 
  relating to the ViiV Healthcare put options and Pfizer preferential 
  dividends represented an increase in the valuation of the put option 
  as a result of updated exchange rate assumptions as well as adjustments 
  to multiples and sales forecasts. 
  The ViiV Healthcare contingent consideration liability is valued 
  on a long-term basis. The potential impact of the COVID-19 pandemic 
  remains uncertain and at 30 June 2020, it has been assumed that there 
  will be no significant impact on the long-term value of the liability. 
  This position remains under review and the amount of the liability 
  will be updated in future quarters as further information on the 
  impact of the pandemic becomes available. An explanation of the accounting 
  for the non-controlling interests in ViiV Healthcare is set out on 
  page 11. 
  Divestments, significant legal charges and other items 
  Divestments and other items included a gain in the period of GBP2,339 
  million arising from the net profit on disposal of the Horlicks and 
  other Consumer Healthcare brands of GBP2,815 million in Q2 2020, 
  after reversal of GBP240 million of embedded derivative gains on 
  the value of the shares taken in prior years. This was partly offset 
  by the related loss on sale of the shares in Hindustan Unilever in 
  Q2 2020 of GBP476 million. Divestments and other items also included 
  a gain from a number of asset disposals and certain other Adjusting 
  items. A charge of GBP6 million (H1 2019: GBP69 million) for significant 
  legal matters included the settlement of existing matters as well 
  as provisions for ongoing litigation. Significant legal cash payments 
  were GBP6 million (H1 2019: GBP8 million). 
  Separation costs 
  From Q2 2020, the Group has started to report additional one-time 
  costs to prepare Consumer Healthcare for separation. These are estimated 
  at GBP600-700 million, excluding transaction costs.

 Q2 2020 
  The net cash inflow from operating activities for the quarter was 
  GBP2,760 million (Q2 2019: GBP1,389 million). The increase primarily 
  reflected a significant reduction in trade receivables as a result 
  of collections following strong sales in Q1 and beneficial timing 
  of payments for returns and rebates and taxes partly offset by reduced 
  operating profits and increased inventory. 
  Total cash payments to Shionogi in relation to the ViiV Healthcare 
  contingent consideration liability in the quarter were GBP232 million 
  (Q2 2019: GBP220 million), of which GBP203 million was recognised 
  in cash flows from operating activities and GBP29 million was recognised 
  in contingent consideration paid within investing cash flows. These 
  payments are deductible for tax purposes. 
  Free cash flow was GBP1,949 million for the quarter (Q2 2019: GBP370 
  million). The increase primarily reflected a significant reduction 
  in trade receivables as a result of collections following strong 
  sales in Q1 2020, beneficial timing of payments for returns and rebates 
  and taxes and higher disposals of intangible assets partly offset 
  by increased inventory and higher dividends to non-controlling interests. 
 
 
 H1 2020 
  The net cash inflow from operating activities for the six months 
  was GBP3,725 million (H1 2019: GBP2,052 million). The increase primarily 
  reflected a reduction in trade receivables as a result of collections 
  following strong sales in Q1, beneficial timing of payments for returns 
  and rebates and taxes, a lower seasonal increase of inventory and 
  improved operating profits. 
  Total cash payments to Shionogi in relation to the ViiV Healthcare 
  contingent consideration liability in the six months were GBP445 
  million (H1 2019: GBP439 million), of which GBP388 million was recognised 
  in cash flows from operating activities and GBP57 million was recognised 
  in contingent consideration paid within investing cash flows. These 
  payments are deductible for tax purposes. 
  Free cash flow was GBP2,480 million for the six months (H1 2019: 
  GBP535 million). The increase primarily reflected a reduction in 
  trade receivables as a result of collections following strong sales 
  in Q1 2020, beneficial timing of payments for returns and rebates 
  and taxes, a lower seasonal increase of inventory and higher disposals 
  of intangible assets and milestone income, partly offset by higher 
  dividends to non-controlling interests. 
 
 
 Net debt 
  At 30 June 2020, net debt was GBP23.4 billion, compared with GBP25.2 
  billion at 31 December 2019, comprising gross debt of GBP31.7 billion 
  and cash and liquid investments of GBP8.3 billion. Net debt decreased 
  due to the GBP3.3 billion proceeds from the Horlicks and other Consumer 
  brands disposal including shares in Hindustan Unilever of GBP2.7 
  billion and GBP0.6 billion of other assets, GBP0.3 billion of other 
  business and asset disposals together with GBP2.5 billion free cash 
  flow, partly offset by cash divested of GBP0.5 billion, dividends 
  paid to shareholders of GBP2.1 billion, GBP1.5 billion of unfavourable 
  exchange impacts from the translation of non-Sterling denominated 
  debt and exchange on other financing items and GBP0.2 billion in 
  additional investments. 
  At 30 June 2020, GSK had short-term borrowings (including overdrafts 
  and lease liabilities) repayable within 12 months of GBP6.0 billion 
  with loans of GBP4.7 billion repayable in the subsequent year. 
 
 
 Returns to shareholders 
 
 
 Quarterly dividends 
  The Board has declared a second interim dividend for 2020 of 19 pence 
  per share (Q2 2019: 19 pence per share). 
  GSK recognises the importance of dividends to shareholders and aims 
  to distribute regular dividend payments that will be determined primarily 
  with reference to the free cash flow generated by the business after 
  funding the investment necessary to support the Group's future growth. 
  The Board currently intends to maintain the dividend for 2020 at 
  the current level of 80p per share, subject to any material change 
  in the external environment or performance expectations. Over time, 
  as free cash flow strengthens, it intends to build free cash flow 
  cover of the annual dividend to a target range of 1.25-1.50x, before 
  returning the dividend to growth. 
  Payment of dividends 
  The equivalent interim dividend receivable by ADR holders will be 
  calculated based on the exchange rate on 6 October 2020. An annual 
  fee of $0.03 per ADS (or $0.0075 per ADS per quarter) is charged 
  by the Depositary. 
  The ex-dividend date will be 13 August 2020, with a record date of 
  14 August 2020 and a payment date of 8 October 2020.

 Segment information 
 
 Operating segments are reported based on the financial information 
  provided to the Chief Executive Officer and the responsibilities 
  of the Corporate Executive Team (CET). GSK reports results under 
  four segments: Pharmaceuticals; Pharmaceuticals R&D; Vaccines and 
  Consumer Healthcare, and individual members of the CET are responsible 
  for each segment. 
  The Pharmaceuticals R&D segment is the responsibility of the Chief 
  Scientific Officer and President, R&D and is reported as a separate 
  segment. The operating profit of this segment excludes the ViiV Healthcare 
  operating profit (including R&D expenditure) that is reported within 
  the Pharmaceuticals segment. 
  The Group's management reporting process allocates intra-Group profit 
  on a product sale to the market in which that sale is recorded, and 
  the profit analyses below have been presented on that basis. 
  Corporate and other unallocated turnover and costs include the results 
  of certain Consumer Healthcare products which are being held for 
  sale in a number of markets in order to meet anti-trust approval 
  requirements, together with the costs of corporate functions.

 Legal matters 
  The Group is involved in significant legal and administrative proceedings, 
  principally product liability, intellectual property, tax, anti-trust, 
  consumer fraud and governmental investigations, which are more fully 
  described in the 'Legal Proceedings' note in the Annual Report 2019. 
  At 30 June 2020, the Group's aggregate provision for legal and other 
  disputes (not including tax matters described on page 22) was GBP0.3 
  billion (31 December 2019: GBP0.2 billion). 
 
  The Group may become involved in significant legal proceedings in 
  respect of which it is not possible to make a reliable estimate of 
  the expected financial effect, if any, that could result from ultimate 
  resolution of the proceedings. In these cases, the Group would provide 
  appropriate disclosures about such cases, but no provision would 
  be made. 
 
  Significant developments since the date of the Annual Report 2019 
  are as follows: 
 
  On 4 May 2020, the US Department of Justice informed the Group that 
  it would be closing its investigation without a recommendation of 
  further action with respect to the Group's use of third-party advisers 
  in China. This followed the US Securities and Exchange Commission's 
  notification to the Group on 8 March 2020 that the SEC similarly 
  was terminating its investigation into these matters. Accordingly, 
  this matter is now concluded. 
 
  On 18 June 2020, the Group received a Civil Investigative Demand 
  (CID) from the US Department of Justice (DOJ) seeking information 
  related to Zantac pursuant to the False Claims Act. The Group is 
  co-operating with the DOJ to provide this information. Additionally, 
  on 18 June 2020, the New Mexico Attorney General filed a lawsuit 
  against multiple defendants, including GSK, relating to Zantac and 
  other products containing ranitidine. 
 
  The ultimate liability for legal claims may vary from the amounts 
  provided and is dependent upon the outcome of litigation proceedings, 
  investigations and possible settlement negotiations. The Group's 
  position could change over time, and, therefore, there can be no 
  assurance that any losses that result from the outcome of any legal 
  proceedings will not exceed by a material amount the amount of the 
  provisions reported in the Group's financial accounts.

 Exchange rates 
 GSK operates in many countries, and earns revenues and incurs costs 
  in many currencies. The results of the Group, as reported in Sterling, 
  are affected by movements in exchange rates between Sterling and 
  other currencies. Average exchange rates, as modified by specific 
  transaction rates for large transactions, prevailing during the period, 
  are used to translate the results and cash flows of overseas subsidiaries, 
  associates and joint ventures into Sterling. Period-end rates are 
  used to translate the net assets of those entities. The currencies 
  which most influenced these translations and the relevant exchange 
  rates were:

 During Q2 2020 average Sterling exchange rates were weaker against 
  the US Dollar, the Euro and Yen compared with the same period in 
  2019. During the six months ended 30 June 2020, average Sterling 
  exchange rates were weaker against the US Dollar and the Yen but 
  stronger against the Euro. Period-end Sterling exchange rates were 
  weaker against the US Dollar, the Euro and Yen compared with the 
  2019 period-end rates. 
 
 
 Net assets 
 The book value of net assets increased by GBP1,780 million from GBP18,357 
  million at 31 December 2019 to GBP20,137 million at 30 June 2020. 
  This primarily reflected the Total profit for the period exceeding 
  the re-measurement losses on defined benefit plans and the dividends 
  paid during the period. 
  The carrying value of investments in associates and joint ventures 
  at 30 June 2020 was GBP390 million (31 December 2019: GBP314 million), 
  with a market value of GBP445 million (31 December 2019: GBP396 million). 
  At 30 June 2020, the net deficit on the Group's pension plans was 
  GBP2,447 million compared with GBP1,921 million at 31 December 2019. 
  The increase in the net deficit primarily arose from decreases in 
  the rates used to discount UK pension liabilities from 2.0% to 1.5%, 
  and US pension liabilities from 3.2% to 2.6%, partly offset by higher 
  UK assets and a decrease in the UK inflation rate from 3.0% to 2.9%. 
  The Group continues to monitor and review the pension asset portfolios 
  in response to the pandemic given the elevated uncertainty inherent 
  for valuations particularly for the property asset class. 
  The estimated present value of the potential redemption amount of 
  the Pfizer put option related to ViiV Healthcare, recorded in Other 
  payables in Current liabilities, was GBP1,069 million (31 December 
  2019: GBP1,011 million). 
  During the quarter, the Group issued an exchangeable bond giving 
  the investors the right to exchange their notes into underlying shares 
  in Theravance Biopharma, Inc. The par value of the exchangeable bond 
  was $280 million and the net proceeds received were $300 million 
  (GBP242 million). 
  Contingent consideration amounted to GBP5,830 million at 30 June 
  2020 (31 December 2019: GBP5,479 million), of which GBP5,436 million 
  (31 December 2019: GBP5,103 million) represented the estimated present 
  value of amounts payable to Shionogi relating to ViiV Healthcare 
  and GBP349 million (31 December 2019: GBP339 million) represented 
  the estimated present value of contingent consideration payable to 
  Novartis related to the Vaccines acquisition. 
  Of the contingent consideration payable (on a post-tax basis) to 
  Shionogi at 30 June 2020, GBP768 million (31 December 2019: GBP730 
  million) is expected to be paid within one year.

 Contingent liabilities 
 There were contingent liabilities at 30 June 2020 in respect of guarantees 
  and indemnities entered into as part of the ordinary course of the 
  Group's business. No material losses are expected to arise from such 
  contingent liabilities. Provision is made for the outcome of legal 
  and tax disputes where it is both probable that the Group will suffer 
  an outflow of funds and it is possible to make a reliable estimate 
  of that outflow. Descriptions of the significant legal disputes to 
  which the Group is a party are set out on page 58. 
 
 
 Business acquisitions and disposals 
 On 1 April 2020, GSK completed its divestment of Horlicks and other 
  Consumer Healthcare nutrition products in India and a number of other 
  countries (excluding Bangladesh) to Unilever and the merger of GSK's 
  Indian listed Consumer Healthcare entity with Hindustan Unilever, 
  an Indian listed public company. GSK received a 5.7% equity stake 
  in Hindustan Unilever and approximately GBP395 million in cash. 
  The divestment in Bangladesh closed on 30 June 2020. Total cash consideration 
  received was approximately GBP177 million. GSK disposed of its equity 
  stake in Hindustan Unilever during May 2020. 
  The cash divested for the disposal of Horlicks and other Consumer 
  Healthcare nutrition products in India and a number of other countries 
  was approximately GBP478 million. 
 
 
 Financial instruments fair value disclosures 
 The following tables categorise the Group's financial assets and 
  liabilities held at fair value by the valuation methodology applied 
  in determining their fair value. Where possible, quoted prices in 
  active markets are used (Level 1). Where such prices are not available, 
  the asset or liability is classified as Level 2, provided all significant 
  inputs to the valuation model used are based on observable market 
  data. If one or more of the significant inputs to the valuation model 
  is not based on observable market data, the instrument is classified 
  as Level 3. Other investments classified as Level 3 in the tables 
  below comprise equity investments in unlisted entities with which 
  the Group has entered into research collaborations and also investments 
  in emerging life science companies.

 Net losses of GBP800 million (H1 2019: net losses of GBP198 million) 
  reported in other operating income and net gains of GBP151 million 
  (H1 2019: net losses of GBP43 million) reported in other comprehensive 
  income were attributable to Level 3 financial instruments held at 
  the end of the period. 
 
  Financial liabilities measured using Level 3 valuation methods at 
  30 June included GBP5,436 million of contingent consideration for 
  the acquisition in 2012 of the former Shionogi-ViiV Healthcare joint 
  venture and GBP349 million of contingent consideration for the acquisition 
  of the Novartis Vaccines business in 2015. Contingent consideration 
  is expected to be paid over a number of years and will vary in line 
  with the future performance of specified products, the achievement 
  of certain milestone targets and movements in certain foreign currencies. 
  The financial liabilities are measured at the present value of expected 
  future cash flows, the most significant inputs to the valuation models 
  being future sales forecasts, the discount rate, the Sterling/US 
  Dollar exchange rate and the probability of success in achieving 
  milestone targets. 
 
 
 The table below shows, on an indicative basis, the income statement

  inputs to the valuation of the largest contingent consideration liabilities.

 The Group transfers financial instruments between different levels 
  in the fair value hierarchy when, as a result of an event or change 
  in circumstances, the valuation methodology applied in determining 
  their fair values alters in such a way that it meets the definition 
  of a different level. There were no transfers between the Level 1 
  and Level 2 fair value measurement categories and no transfers to 
  or from the Level 3 category in the period. Transfers from Level 
  3 in the six months to 30 June 2019 related to equity investments 
  in companies which were listed on stock exchanges during that period. 
 
 
 The following methods and assumptions were used to measure the fair 
  value of the significant financial instruments carried at fair value 
  on the balance sheet: 
 
 --   Cash and cash equivalents carried at fair value - based on net 
       asset value of the funds 
 
 --   Other investments - equity investments traded in an active market 
       determined by reference to the relevant stock exchange quoted bid 
       price; other equity investments determined by reference to the 
       current market value of similar instruments, recent financing rounds 
       or the discounted cash flows of the underlying net assets 
 
 --   Contingent consideration for business acquisitions and divestments 
       - based on present values of expected future cash flows 
 
 --   Interest rate swaps, foreign exchange forward contracts, swaps 
       and options - based on the present value of contractual cash flows 
       or option valuation models using market-sourced data (exchange 
       rates or interest rates) at the balance sheet date 
 
 --   Company-owned life insurance policies - based on cash surrender 
       value 
 
 --   Trade receivables carried at fair value - based on invoiced amount. 
 
 
 There are no material differences between the carrying value of the 
  Group's other financial assets and liabilities and their estimated 
  fair values, with the exception of bonds, for which the carrying 
  values and fair values are set out in the table below:

 The following methods and assumptions are used to estimate the fair 
  values of financial assets and liabilities which are not measured 
  at fair value on the balance sheet: 
 
 --   Liquid investments - approximates to the carrying amount 
 
 --   Cash and cash equivalents carried at amortised cost - approximates 
       to the carrying amount 
 
 --   Short-term loans, overdrafts and commercial paper - approximates 
       to the carrying amount because of the short maturity of these instruments 
 
 --   Long-term loans - based on quoted market prices (a Level 1 fair 
       value measurement) in the case of European and US Medium Term Notes 
       and other fixed rate borrowings; approximates to the carrying amount 
       in the case of other fixed rate borrowings and floating rate bank 
       loans 
 
 --   Receivables and payables, including put options, carried at amortised 
       cost - approximates to the carrying amount 
 
 --   Lease obligations - approximates to the carrying amount. 
 
 
 Put option 
  Other payables in Current liabilities includes the present value 
  of the expected redemption amount of the Pfizer put option over its 
  non-controlling interest in ViiV Healthcare of GBP1,069 million. 
  This reflects a number of assumptions around future sales and profit 
  forecasts, multiples and forecast exchange rates. The forecast exchange 
  rates used are consistent with market rates at 30 June 2020. 
  The table below shows on an indicative basis the income statement 
  and balance sheet sensitivity to reasonably possible changes in the

                          systems may lead to harm to our patients, workforce 
                          and customers, disruption to our business and/or loss 
                          of commercial or strategic advantage, damage to our 
                          reputation or regulatory sanction. 
 
 Supply continuity       Failure to deliver a continuous supply of compliant 
                          finished product; inability to respond effectively 
                          to a crisis incident in a timely manner to recover 
                          and sustain critical operations. 
 
 
 
 COVID-19 pandemic 
  The potential impact of the COVID-19 pandemic on GSK's trading performance 
  and all our Principal risks has been assessed with mitigation plans 
  put in place. Up to the date of this report, the pandemic, has as 
  anticipated, impacted the Group performance during the first half 
  of 2020 primarily in demand for Vaccines as a result of containment 
  measures impacting customers' ability and willingness to access vaccination 
  services across all regions. We continue to monitor the situation 
  closely, as this is clearly a very dynamic and uncertain situation, 
  with the ultimate severity, duration and impact unknown at this point 
  including the potential impacts on trading results, our clinical 
  trials, our supply continuity and our employees. The situation could 
  change at any time and there can be no assurance that COVID-19 will 
  not have a material adverse impact on the future results of the Group. 
 
 
 Reporting definitions 
 
 
 Total and Adjusted results 
  Total reported results represent the Group's overall performance. 
  GSK also uses a number of adjusted, non-IFRS, measures to report 
  the performance of its business. Adjusted results and other non-IFRS 
  measures may be considered in addition to, but not as a substitute 
  for or superior to, information presented in accordance with IFRS. 
  Adjusted results are defined on page 10 and other non-IFRS measures 
  are defined below. 
  Free cash flow 
  Free cash flow is defined as the net cash inflow from operating activities 
  less capital expenditure on property, plant and equipment and intangible 
  assets, contingent consideration payments, net finance costs, and 
  dividends paid to non-controlling interests plus proceeds from the 
  sale of property, plant and equipment and intangible assets, and 
  dividends received from joint ventures and associates. It is used 
  by management for planning and reporting purposes and in discussions 
  with and presentations to investment analysts and rating agencies. 
  Free cash flow growth is calculated on a reported basis. A reconciliation 
  of net cash inflow from operations to free cash flow is set out on 
  page 66. 
  Free cash flow conversion 
  Free cash flow conversion is free cash flow as a percentage of earnings. 
  Working capital 
  Working capital represents inventory and trade receivables less trade 
  payables. 
  CER and AER growth 
  In order to illustrate underlying performance, it is the Group's 
  practice to discuss its results in terms of constant exchange rate 
  (CER) growth. This represents growth calculated as if the exchange 
  rates used to determine the results of overseas companies in Sterling 
  had remained unchanged from those used in the comparative period. 
  CER% represents growth at constant exchange rates. GBP% or AER% represents 
  growth at actual exchange rates. 
  Pro-forma growth 
  The acquisition of the Pfizer consumer healthcare business completed 
  on 31 July 2019 and so GSK's reported results for Q2 2020 include 
  three months of results of the former Pfizer consumer healthcare 
  business from 1 April 2020. 
  The Group has presented pro-forma growth rates at CER for turnover, 
  Adjusted operating profit and operating profit by business taking 
  account of this transaction. Pro-forma growth rates at CER for the 
  quarter are calculated comparing reported results for Q2 2020, calculated 
  applying the exchange rates used in the comparative period, with 
  the results for Q2 2019 adjusted to include the equivalent three 
  months of results of the former Pfizer consumer healthcare business 
  during Q2 2019, as consolidated (in US$) and included in Pfizer's 
  US GAAP results. Similarly, pro-forma growth rates at CER for the 
  six months to 30 June 2020 are calculated comparing reported results 
  for the six months to 30 June 2020, calculated applying the exchange 
  rates used in the comparative period, with the results for the six 
  months to 30 June 2019, adjusted to include the equivalent six months 
  of results of the former Pfizer consumer healthcare business, as 
  consolidated (in US$) and included in Pfizer's US GAAP results.

 Outlook, assumptions and cautionary statements 
 
 
 2020 guidance 
  While we are maintaining our 2020 Adjusted EPS guidance, there remain 
  notable risks to business performance over the balance of the year. 
  In particular, the outcome is dependent on the timing of a recovery 
  in vaccination rates, particularly in the US, which we anticipate 
  in the third quarter. If we were to experience a delay in this recovery 
  we could see a significant impact in 2020. In the case of, for example, 
  a three month delay, the impact on adjusted EPS would be up to 5 
  percentage points. 
  2016-2020 outlook 
  In May 2015, GSK announced that it expected Group sales to grow at 
  CER at a low-to-mid single digits percentage CAGR and Adjusted EPS 
  to grow at CER at a mid-to-high single digit percentage CAGR for 
  the period 2016-2020. On 3 December 2018, GSK announced that it continued 
  to expect to deliver on its previously published Group outlooks to 
  2020, but, following the acquisition of Tesaro, expected Adjusted 
  EPS growth at CER for the period 2016-2020 to be at the bottom end 
  of the mid-to-high single digit percentage CAGR range. These outlooks 
  are based on 2015 exchange rates. 
  Assumptions related to 2020 guidance and 2016-2020 outlook 
  In outlining the expectations for 2020 and the five-year period 2016-2020, 
  the Group has made certain assumptions about the healthcare sector, 
  the different markets in which the Group operates and the delivery 
  of revenues and financial benefits from its current portfolio, pipeline 
  and restructuring programmes. 
  For the Group specifically, over the period to the end of 2020, GSK 
  expects further declines in sales of Seretide/Advair. The introduction 
  of a generic alternative to Advair in the US has been factored into 
  the Group's assessment of its future performance. The Group assumes 
  no premature loss of exclusivity for other key products over the 
  period. 
  The assumptions for the Group's revenue, earnings and dividend expectations 
  assume no material interruptions to supply of the Group's products, 
  no material mergers, acquisitions or disposals, except for the acquisition 
  of Tesaro, the divestment of Horlicks and other Consumer Healthcare 
  products to Unilever and the formation of a new Consumer Healthcare 
  Joint Venture with Pfizer, all announced in December 2018, no material 
  litigation or investigation costs for the Company (save for those 
  that are already recognised or for which provisions have been made), 
  no share repurchases by the Company, and no change in the Group's 
  shareholdings in ViiV Healthcare. The assumptions also assumed no 
  material changes in the macro-economic and healthcare environment 
  over the period. The 2020 guidance and 2016-2020 outlook have factored 
  in all divestments and product exits since 2015, including the divestment 
  and exit of more than 130 non-core tail brands (GBP0.5 billion in 
  annual sales) as announced on 26 July 2017 and the product divestments 
  planned in connection with the formation of the Consumer Healthcare 
  Joint Venture with Pfizer. 
  The Group's expectations assume successful delivery of the Group's 
  integration and restructuring plans over the period 2016-2020, including 
  the extension and enhancement to the combined programme announced 
  on 26 July 2017, the new Major restructuring plan announced on 25 
  July 2018, the Consumer Healthcare Joint Venture integration programme 
  and the new Separation Preparation programme. They also assume that 
  the integration and investment programmes following the Tesaro acquisition 
  and the Consumer Healthcare Joint Venture with Pfizer over this period 
  are delivered successfully. Material costs for investment in new 
  product launches and R&D have been factored into the expectations 
  given. Given the potential development options in the Group's pipeline, 
  the outlook may be affected by additional data-driven R&D investment 
  decisions. The expectations are given on a constant currency basis 
  (2016-2020 outlook at 2015 CER). 
  Assumptions and cautionary statement regarding forward-looking statements 
  The Group's management believes that the assumptions outlined above 
  are reasonable, and that the aspirational targets described in this 
  report are achievable based on those assumptions. However, given 
  the longer term nature of these expectations and targets, they are 
  subject to greater uncertainty, including potential material impacts 
  if the above assumptions are not realised, and other material impacts 
  related to foreign exchange fluctuations, macro-economic activity, 
  the impact of outbreaks, epidemics or pandemics, such as the COVID-19 
  pandemic and ongoing challenges and uncertainties posed by the COVID-19 
  pandemic for businesses and governments around the world, changes 
  in regulation, government actions or intellectual property protection, 
  actions by our competitors, and other risks inherent to the industries 
  in which we operate. 
  This document contains statements that are, or may be deemed to be, 
  "forward-looking statements". Forward-looking statements give the 
  Group's current expectations or forecasts of future events. An investor 
  can identify these statements by the fact that they do not relate 
  strictly to historical or current facts. They use words such as 'anticipate', 
  'estimate', 'expect', 'intend', 'will', 'project', 'plan', 'believe', 
  'target' and other words and terms of similar meaning in connection 
  with any discussion of future operating or financial performance. 
  In particular, these include statements relating to future actions, 
  prospective products or product approvals, future performance or 
  results of current and anticipated products, sales efforts, expenses, 
  the outcome of contingencies such as legal proceedings, dividend 
  payments and financial results. Other than in accordance with its 
  legal or regulatory obligations (including under the Market Abuse 
  Regulation, the UK Listing Rules and the Disclosure and Transparency 
  Rules of the Financial Conduct Authority), the Group undertakes no 
  obligation to update any forward-looking statements, whether as a 
  result of new information, future events or otherwise. The reader 
  should, however, consult any additional disclosures that the Group 
  may make in any documents which it publishes and/or files with the 
  SEC. All readers, wherever located, should take note of these disclosures. 
  Accordingly, no assurance can be given that any particular expectation 
  will be met and investors are cautioned not to place undue reliance 
  on the forward-looking statements. 
  Forward-looking statements are subject to assumptions, inherent risks 
  and uncertainties, many of which relate to factors that are beyond 
  the Group's control or precise estimate. The Group cautions investors 
  that a number of important factors, including those in this document, 
  could cause actual results to differ materially from those expressed 
  or implied in any forward-looking statement. Such factors include, 
  but are not limited to, those discussed under Item 3.D 'Risk Factors' 
  in the Group's Annual Report on Form 20-F for 2019 and any impacts 
  of the COVID-19 pandemic. Any forward looking statements made by 
  or on behalf of the Group speak only as of the date they are made 
  and are based upon the knowledge and information available to the 
  Directors on the date of this report. 
  Cautionary statement regarding pro-forma growth rates 
  The pro-forma growth rates at CER in this Results Announcement have 
  been provided to illustrate the position in Q2 2020 relative to the 
  position in Q2 2019 as if, for the purposes of the Q2 2019 results, 
  the acquisition of the Pfizer consumer healthcare business had taken 
  place as at 31 July 2018 and that, accordingly, three months of results 
  of the former Pfizer consumer healthcare business were included in 
  Q2 2019. Similarly, pro-forma growth rates have been provided to 
  illustrate the position for the six months to 30 June 2020 relative 
  to the position for the six months to 30 June 2019 as if, for the 
  purposes of the six months to 30 June 2019 results, the acquisition 
  of the Pfizer consumer healthcare business had taken place as at 
  31 July 2018 and that, accordingly, six months of results of the 
  former Pfizer consumer healthcare business were included in the six 
  months to 30 June 2019. The results of the former Pfizer consumer 
  healthcare business included for Q2 2019 and the six months to 30 
  June 2019 are as consolidated (in US$) and included in Pfizer's US 
  GAAP results. The results for Q2 2020 and the six months to 30 June 
  2020 used to calculate the pro-forma growth rates are as reported 
  at CER. 
  The pro-forma growth rates have been provided for illustrative purposes 
  only and, by their nature, address a hypothetical situation and therefore 
  do not represent the Group's actual growth rates. The pro-forma growth 
  rates do not purport to represent what the Group's results of operations 
  actually would have been if the Pfizer acquisition had been completed 
  on the date indicated, nor do they purport to represent the results 
  of operations at any future date. In addition, the pro-forma growth 
  rates do not reflect the effect of anticipated synergies and efficiencies 
  or accounting and reporting differences associated with the acquisition 
  of the Pfizer consumer healthcare business.

 Independent review report to GlaxoSmithKline plc 
 
 
 We have been engaged by GlaxoSmithKline plc ("the company") to review 
  the condensed financial information (the "interim financial statements") 
  in the Results Announcement of the company for the three and six 
  months ended 30 June 2020. 
 
 
 What we have reviewed 
 The interim financial statements comprises: 
 --    the income statement and statement of comprehensive income for 
        the three and six month periods ended 30 June 2020 on pages 46 
        to 48; 
 --    the balance sheet as at 30 June 2020 on page 53; 
 --    the statement of changes in equity for the six month period then 
        ended on page 54; 
 --    the cash flow statement for the six month period then ended on 
        page 55; and 
 --    the accounting policies and basis of preparation and the explanatory 
        notes to the interim financial statements on pages 49 to 52 and 
        56 to 64 . 
 
 We have read the other information contained in the Results Announcement, 
  including the non-IFRS measures contained on pages 49 to 52 and 56 
  to 65, and considered whether it contains any apparent misstatements 
  or material inconsistencies with the information in the condensed 
  set of financial statements. 
 
  This report is made solely to the company in accordance with International 
  Standard on Review Engagements (UK and Ireland) 2410 "Review of Interim 
  Financial Information Performed by the Independent Auditor of the 
  Entity" issued by the Financial Reporting Council. Our work has been 
  undertaken so that we might state to the company those matters we 
  are required to state to it in an independent review report and for 
  no other purpose. To the fullest extent permitted by law, we do not 
  accept or assume responsibility to anyone other than the company, 
  for our review work, for this report, or for the conclusions we have 
  formed. 
 
  Directors' responsibilities 
  The Results Announcement of the company, including the interim financial 
  statements, is the responsibility of, and has been approved by, the 
  directors. The directors are responsible for preparing the Results 
  Announcement of the company in accordance with the Disclosure Guidance 
  and Transparency Rules of the United Kingdom's Financial Conduct 
  Authority. 
 
  As disclosed in Note 1, the annual financial statements of the company 
  are prepared in accordance with IFRSs as adopted by the European 
  Union. The interim financial statements included in this Results 
  Announcement have been prepared in accordance with International 
  Accounting Standard 34 "Interim Financial Reporting" as adopted by 
  the European Union. 
 
  Our responsibility 
  Our responsibility is to express to the company a conclusion on the 
  interim financial statements in the Results Announcement based on 
  our review. 
 
  Scope of review 
  We conducted our review in accordance with International Standard 
  on Review Engagements (UK and Ireland) 2410 "Review of Interim Financial 
  Information Performed by the Independent Auditor of the Entity" issued 
  by the Financial Reporting Council for use in the United Kingdom. 
  A review of interim financial information consists of making inquiries, 
  primarily of persons responsible for financial and accounting matters, 
  and applying analytical and other review procedures. A review is 
  substantially less in scope than an audit conducted in accordance 
  with International Standards on Auditing (UK) and consequently does 
  not enable us to obtain assurance that we would become aware of all 
  significant matters that might be identified in an audit. Accordingly, 
  we do not express an audit opinion. 
 
  Conclusion 
  Based on our review, nothing has come to our attention that causes 
  us to believe that the interim financial statements in the Results 
  Announcement for the three and six months ended 30 June 2020 are 
  not prepared, in all material respects, in accordance with International 
  Accounting Standard 34 as adopted by the European Union and the Disclosure 
  Guidance and Transparency Rules of the United Kingdom's Financial 
  Conduct Authority.
