 Emma Walmsley, Chief Executive Officer, GSK said: "GSK delivered 
  an excellent performance in Q2. We expect this positive momentum 
  to continue through the second half of the year driving us towards 
  the better end of our earnings guidance range for 2021, and meaningful 
  performance improvement in 2022. We continue to strengthen our pipeline 
  and are advancing well towards separation. Our clear priority is 
  to focus on execution, unlocking the value of Consumer Healthcare 
  and delivering the step-change in growth and performance we now see 
  for GSK."

 2021 guidance 
 We reconfirm our guidance range for 2021 for a decline of mid to 
  high-single digit percent Adjusted EPS at CER, excluding any contribution 
  from COVID-19 solutions. 
  In 2021, as planned we will continue to increase investment in our 
  pipeline, build on our top-line momentum for key growth drivers and 
  largely complete readiness for separation. Assuming healthcare systems 
  and consumer trends approach normality in the second half of the 
  year, we continue to expect Pharmaceutical revenue to grow flat to 
  low-single digits at CER and Consumer Healthcare revenue to grow 
  low to mid-single digits at CER (excluding brands divested/under 
  review) with above market growth. For our Vaccines business, as noted 
  at the time of announcing full-year 2020 results, we anticipated 
  disruption during the first half of the year, given governments' 
  prioritisation of COVID-19 vaccination programmes and ongoing measures 
  to contain the pandemic. This was expected to impact adult and adolescent 
  immunisations, including Shingrix, notably in the US and this is 
  reflected in our first-half year 2021 Vaccines performance. We are 
  encouraged by the rate at which COVID-19 vaccinations are being deployed 
  in many countries, particularly the US and UK, which provides support 
  for healthcare systems returning to normal, though we are seeing 
  global differentiation in the pace of deployment in other major markets. 
  There remains, however, uncertainty as to the impact of COVID-19, 
  the speed of deployment of mass immunisation programmes and easing 
  of pandemic conditions. In the second half of the year we continue 
  to expect strong recovery and contribution to growth but, with Shingrix 
  sales recovering more slowly in ex-US markets, we now expect Vaccines 
  revenue for 2021 to be broadly flat. We remain confident in the underlying 
  demand for our Vaccine products. 
  Our strong Q2 2021 performance gives us confidence that, providing 
  we continue to see improving demand for adult vaccinations through 
  the balance of 2021, as well as healthcare systems and consumer trends 
  approaching normality, we are likely to deliver full-year Adjusted 
  EPS towards the better end of our guidance range which is for a decline 
  of mid-to-high single-digit percentage at CER excluding any contribution 
  from COVID-19 solutions. 
  2021 COVID-19 solutions expectations 
  In H1 2021, we had COVID-19 solution sales of GBP276 million including 
  GBP260 million of pandemic vaccines of which GBP258 million were 
  pandemic adjuvant sales and GBP16 million of the treatment sotrovimab. 
  The contribution to H1 Adjusted EPS was approximately 7%. For the 
  full year, we expect that the COVID-19 solutions will contribute 
  approximately between 4% to 6% of Adjusted EPS growth. The outcome 
  within that range is dependent upon the success of sotrovimab contracting 
  for 2021, and of pandemic adjuvant contracting for 2022 and the resulting 
  potential charges within COGS as we continue to manufacture for this 
  potential. 
  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 2021 ($1.39/GBP1, EUR1.17/GBP1 
  and Yen 153/GBP1) for the rest of 2021, the estimated negative impact 
  on 2021 Sterling turnover growth would be 5% and if exchange gains 
  or losses were recognised at the same level as in 2020, the estimated 
  negative impact on 2021 Sterling Adjusted EPS growth would be around 
  10%.

                       ------  -------  ------- 
 
 
 
 Group turnover was GBP8,092 million in the quarter, up 6% AER, 15% 
  CER. 
 
  Pharmaceuticals turnover in the quarter was GBP4,229 million, up 
  3% AER, 12% CER. The quarter results show significant growth over 
  the same quarter last year, driven by strong growth in New and Specialty 
  products, favourable US RAR adjustments and a prior year comparator 
  that was impacted by destocking of COVID-19 related first quarter 
  additional demand. 
 
  Vaccines turnover grew 39% AER, 49% CER to GBP1,571 million, primarily 
  driven by pandemic adjuvant sales, higher demand for DTPa-containing 
  vaccines in the US and higher demand for Bexsero in the US and in 
  Europe. Vaccines turnover excluding pandemic vaccines grew 16% AER, 
  24% CER to GBP1,311 million. 
 
  Consumer Healthcare turnover declined 4% AER, but increased 3% CER 
  to GBP2,292 million. Sales excluding brands divested/under review 
  declined 1% AER but increased 7% CER supported by a favourable comparative 
  in Q2 2020 as a result of destocking including the reversal of the 
  benefit of the accelerated purchases in the first quarter in 2020 
  across all categories as a result of the COVID-19 pandemic. 
 
  Operating profit 
  Total operating profit was GBP1,675 million in Q2 2021 compared 
  with GBP2,850 million in Q2 2020. The total operating margin was 
  20.7%. This decrease in Total operating profit primarily reflected 
  the net profit on disposal of the Horlicks and other Consumer brands 
  of GBP2,304 million in the prior period partly offset by the related 
  loss on sale of the shares in Hindustan Unilever of GBP476 million. 
 
  Adjusted operating profit was GBP2,158 million, 23% higher than 
  Q2 2020 at AER, 43% higher at CER on a turnover increase of 15% 
  CER. The Adjusted operating margin of 26.7% was 3.7 percentage points 
  higher at AER, and 5.6 percentage points higher on a CER basis than 
  in Q2 2020. The increase in Adjusted operating profit primarily 
  reflected leverage from a favourable comparison to destocking in 
  Q2 2020 in Pharmaceuticals and Consumer Healthcare, GBP258 million 
  of pandemic adjuvant sales, increased demand for Meningitis and 
  DTPa-containing Vaccines, a favourable prior period RAR adjustment 
  in Pharmaceuticals, continued tight control of ongoing costs and 
  benefits from continued restructuring. This was partly offset by 
  increased investment behind launches and increased investment in 
  R&D. 
 
  Earnings per share 
  Total EPS was 27.9p, compared with 45.5p in Q2 2020. This primarily 
  reflected an unfavourable comparison to net profit on disposal in 
  Q2 2020 of the Horlicks and other Consumer brands partly offset 
  by the related loss on sale of the shares in Hindustan Unilever. 
  In Q2 2021 a credit of GBP325 million to Taxation was recorded resulting 
  from the revaluation of deferred tax assets following enactment 
  of the proposed change of UK corporation tax rate from 19% to 25% 
  (effective 2023). 
 
  Adjusted EPS was 28.1p compared with 19.2p in Q2 2020, up 46% AER, 
  71% CER, on a 43% CER increase in Adjusted operating profit reflecting 
  sales increases in Pharmaceuticals and Consumer Healthcare including 
  a benefit from destocking in Q2 2020 and increased Vaccines sales 
  including pandemic adjuvant sales, lower interest costs, a lower 
  effective tax rate and a lower non-controlling interest allocation 
  of Consumer Healthcare and ViiV profits. The contribution to growth 
  from COVID-19 solutions was approximately 20% AER, 21% CER. 
 
  Cash flow 
  The net cash inflow from operating activities for the quarter was 
  GBP1,292 million (Q2 2020: GBP2,760 million). Free cash inflow was 
  GBP316 million for the quarter (Q2 2020: GBP1,949 million inflow). 
  The decrease primarily reflected an adverse comparison to the significant 
  reduction in trade receivables in Q2 2020 as a result of collections 
  following strong sales in Q1 2020, adverse timing of returns and 
  rebates and taxes compared to Q2 2020, increased purchases of intangible 
  assets and reduced proceeds from disposal of intangible assets as 
  the Consumer Brands Disposal programme is now complete. This was 
  partly offset by increased operating profit, a lower seasonal increase 
  in inventory and lower dividends to non-controlling interests.

 Group turnover         15,510      (7)      (1) 
 
 
 
 Group turnover was GBP15,510 million in the six months, down 7% 
  AER, 1% CER. 
 
  Pharmaceuticals turnover in the six months was GBP8,111 million, 
  down 5% AER but up 2% CER, with growth from Respiratory and HIV 
  partly offset by declines in Established Pharmaceuticals. In the 
  first half of last year, the additional COVID-19 related demand 
  experienced towards the end of the first quarter was broadly reversed 
  in the second quarter. In the current year, the market environment 
  continues to be impacted by COVID-19, impacting our Established 
  Pharmaceuticals products in International and Europe regions. 
 
  Vaccines turnover declined 5% AER, but was flat at CER to GBP2,795 
  million, primarily driven by pandemic adjuvant sales, offset by 
  the adverse impact of the COVID-19 pandemic on Shingrix. Vaccines 
  turnover excluding pandemic vaccines declined 14% AER, 9% CER . 
 
  Consumer Healthcare turnover for the six months declined 12% AER, 
  7% CER to GBP4,604 million largely driven by the divestment programme 
  which completed in Q1 2021 as well as the H1 2020 comparative including 
  a particularly strong first quarter given accelerated purchasing 
  due to the COVID-19 pandemic. 
 
  Operating profit 
  Total operating profit was GBP3,368 million in H1 2021 compared 
  with GBP4,864 million in H1 2020. The total operating margin was 
  21.7%. The decrease in total operating profit primarily reflected 
  an unfavourable comparison to the net profit on disposal in Q2 2020 
  of the Horlicks and other Consumer brands and resultant sale of 
  shares in Hindustan Unilever. 
 
  Adjusted operating profit was GBP4,039 million, 9% lower than H1 
  2020 at AER, but 3% higher at CER on a turnover decline of 1% CER. 
  The Adjusted operating margin of 26.0% was 0.4 percentage points 
  lower at AER, but 1.1 percentage points higher on a CER basis than 
  in H1 2020. The increase in Adjusted operating profit primarily 
  reflected a benefit from incremental pandemic adjuvant sales, sales 
  growth in Pharmaceuticals and tight control of ongoing costs including 
  reduced promotional and variable spending across all three businesses 
  as a result of the COVID-19 lockdowns, favourable legal settlements 
  compared to increased legal costs in 2020 and benefits from continued 
  restructuring across the Group. This was partly offset by an adverse 
  mix in Vaccines as well as higher supply chain costs and under-recoveries, 
  divestments in Consumer Healthcare and increased investment in R&D 
  across Vaccines and Pharmaceuticals. 
 
  Earnings per share 
  Total EPS was 49.4p, compared with 77.0p in H1 2020. This primarily 
  reflected an unfavourable comparison to the net profit on disposal 
  in Q2 2020 of the Horlicks and other Consumer brands partly offset 
  by the related loss on sale of the shares in Hindustan Unilever. 
  These factors were partly offset by lower major restructuring costs 
  and lower re-measurement charges on the contingent consideration 
  liabilities. In Q2 2021 a credit of GBP325 million to Taxation was 
  recorded resulting from the revaluation of deferred tax assets following 
  enactment of the proposed change of the UK corporation tax rate 
  from 19% to 25% (effective 2023). 
 
  Adjusted EPS was 51.0p compared with 56.9p in H1 2020, down 10% 
  AER but up 2% CER, on a 3% CER increase in Adjusted operating profit 
  reflecting incremental pandemic adjuvant sales, sales increases 
  in Pharmaceuticals, tight cost control and favourable legal settlements, 
  lower interest costs, a lower non-controlling interest allocation 
  of Consumer Healthcare and ViiV profits, partly offset by lower 
  non-pandemic sales in Vaccines, primarily Shingrix and a higher 
  effective tax rate. The contribution to growth from COVID-19 solutions 
  was approximately 7% AER, 7% CER. 
 
  Cash flow 
  The net cash inflow from operating activities for the six months 
  was GBP1,623 million (H1 2020: GBP3,725 million). Free cash inflow 
  was GBP313 million for the six months (H1 2020: GBP2,480 million 
  inflow). The decrease primarily reflected adverse exchange impacts, 
  reduction in trade receivables in H1 2020 as a result of collections 
  following strong sales in Q1 2020, adverse timing of returns and 
  rebates and taxes compared to Q2 2020 and increased inventory, increased 
  purchases of intangible assets and reduced proceeds from disposal 
  of intangible assets as the Consumer Brands Disposal programme is 
  now complete. This was partly offset by increased operating profit 
  and lower dividends to non-controlling interests. 
 
 
 R&D pipeline 
 
 
 We focus on the science of the immune system, human genetics and 
  advanced technologies to develop Vaccines and Specialty Medicines 
  in four core therapeutic areas - Infectious Diseases, HIV, Oncology 
  and Immunology/Respiratory. We also remain open to opportunities 
  outside these core therapy areas where there are scale opportunities 
  consistent with the science of the immune system and human genetic 
  validation. 
 
  As disclosed at the Investor Update on 23 June 2021, the company 
  has a robust late-stage R&D pipeline with many assets having the 
  potential to be first-in-class or best-in-class, as well as offering 
  significant strategic lifecycle opportunities . The late-stage pipeline 
  is expected to help deliver the sales ambition set by the company 
  for 2021-2026 and beyond. 
 
  O ur R&D pipeline currently comprises 63 Vaccines and Specialty Medicines.

 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 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 
       including the one-off impact of the revaluation of deferred tax 
       assets and liabilities following enactment of the increase in the 
       headline rate of UK corporation tax from 19% to 25% (effective 
       2023) 
 --   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. 
  The enactment of the increase in the headline rate of UK Corporation 
  tax from 19% to 25% (effective 2023) resulted in a credit of GBP325 
  million in Q2 2021. Due to the magnitude, GSK has reported this 
  credit as an Adjusting item in Q2 2021 and H1 2021 so that it does 
  not obscure the key trends in the Group's performance for the period. 
  Reconciliations between Total and Adjusted results, providing further 
  information on the key Adjusting items, are set out on pages 23, 
  24, 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. 
 
 
 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 86% of the Total 
  earnings and 83% of the Adjusted earnings of ViiV Healthcare for 
  2020. 
  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 2021, the liability, 
  which is discounted at 8.0%, stood at GBP5,199 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 2021 were GBP419 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 52 and 53 of the Annual Report 
  2020.

 Pharmaceuticals turnover in the quarter was GBP4,229 million, up 
  3% AER, 12% CER. 
  In the quarter results show significant growth over the same quarter 
  last year, driven by strong growth in New and Specialty products, 
  favourable US RAR adjustments and a prior year comparator that was 
  impacted by destocking in the quarter. 
  Q2 2020 was weakened as it was the first full quarter of COVID-19 
  pandemic impact and included some destocking of COVID-19 related 
  additional demand in the first quarter. The impact of this prior 
  year destocking accounted for approximately 3 percentage points of 
  growth at CER in the current quarter. The prior period RAR adjustment, 
  including the impact of lower than expected Medicaid usage on a number 
  of products, also accounted for approximately 4 percentage points 
  of growth at CER in the quarter. 
  New and Specialty sales of GBP2,304 million grew 14% AER, 25% CER, 
  with ongoing growth from Respiratory, Oncology, Immuno-Inflammation 
  and HIV. 
  Respiratory sales were up 25% AER, 36% CER, to GBP717 million, on 
  growth of Trelegy and Nucala, and our Immuno-Inflammation and Oncology 
  portfolios continue to show double digit growth. HIV sales grew 4% 
  AER, 14% CER, to GBP1,235 million, including the favourable impact 
  on growth of prior year destocking, with growth of Dovato exceeding 
  the decline in Triumeq. Sales of Established Pharmaceuticals declined 
  8% AER but were flat at CER, to GBP1,925 million. 
  In the US, sales grew 10% AER, 23% CER. Continued growth of Nucala, 
  Trelegy, Benlysta and Dovato was supplemented by growth in Established 
  Products. This reflected strong demand for Established Respiratory 
  products in the COVID-19 environment and certain supply challenges 
  faced by generic competitor products, plus the benefit of a favourable 
  prior period RAR adjustment in the quarter. 
  In Europe, sales grew 3% AER, 6% CER, including the favourable impact 
  on growth of prior year destocking, with double digit growth of Trelegy, 
  Nucala, Anoro, Benlysta and Zejula. HIV two-drug regimens growth 
  exceeded the declines in Tivicay and Triumeq. The Established Pharmaceuticals 
  portfolio declined 8% AER, 6% CER, impacted by generic competition 
  including Seretide, Duodart and Volibris. 
  International declined 7% AER but grew 3% CER. Growth from the Respiratory 
  portfolio and HIV including the impact of tender phasing was offset 
  by declines in Established Pharmaceuticals which continue to be impacted 
  by COVID-19 suppressed antibiotics markets and increased generic 
  competition in Japan on Xyzal and Avolve. 
  Respiratory 
  Total Respiratory sales were up 25% AER, 36% CER, with growth from 
  Trelegy, Nucala and Anoro. International Respiratory sales grew 41% 
  AER, 51% CER including Nucala, up 22% AER, 35% CER and Trelegy up 
  more than 100% AER and CER including the impact of Trelegy Asthma 
  launched in Japan in Q4 2020. In Europe, Respiratory grew 23% AER, 
  25% CER with double digit growth of Anoro, Trelegy and Nucala. In 
  the US, Respiratory grew 22% AER, 37% CER, driven by Trelegy and 
  Nucala and the impact of a prior period RAR adjustment. 
  Sales of Nucala were GBP292 million in the quarter and grew 21% AER, 
  32% CER, with consistent, strong growth across all three regions. 
  US sales were up 21% AER, 35% CER to GBP182 million and International 
  sales of GBP45 million grew 22% AER, 35% CER. Europe sales of GBP65 
  million grew 20% AER, 22% CER. 
  Trelegy sales were up 50% AER, 64% CER to GBP291 million driven by 
  growth in all regions. In the US, sales benefited from the new asthma 
  indication approved and launched in Q3 2020, with sales up 46% AER, 
  64% CER. In Europe, sales grew 36% AER, 36% CER and in International, 
  where Trelegy asthma was approved in Japan in Q4 2020, sales grew 
  more than 100% AER and CER to GBP38 million. 
  HIV 
  HIV sales were GBP1,235 million with growth of 4% AER, 14% CER in 
  the quarter. Q2 2021 growth benefited from customer destocking in 
  the Q2 2020 comparator, following customer stock building in Q1 2020 
  due to COVID-19 mainly in the US and Europe. Together with the timing 
  of Tivicay tenders in International, these two factors accounted 
  for 5 and 6 percentage points of CER growth respectively. The mature 
  portfolio drove 1 percentage point of CER decline. Triumeq sales 
  were GBP466 million, down 20% AER, 13% CER and Tivicay sales were 
  GBP407 million, up 9% AER, 21% CER. 
  New HIV products Juluca, Dovato, Rukobia and Cabenuva delivered sales 
  of GBP330 million representing 27% of the total HIV portfolio. Sales 
  of the two drug regimens Juluca and Dovato were GBP132 million and 
  GBP184 million respectively with combined growth of 75% AER, 90% 
  CER. Rukobia sales were GBP10 million. Cabenuva, the first long acting 
  injectable, recorded quarterly sales of GBP4 million. 
  In the US, total sales were GBP716 million with decline of 3% AER, 
  but growth of 8% CER. New HIV products delivered sales of GBP216 
  million, including: Dovato GBP102 million growth of more than 100% 
  AER and more than 100% CER, Juluca GBP101 million growth of 12% AER, 
  24% CER, Rukobia GBP10 million and Cabenuva GBP3 million. Combined 
  Tivicay and Triumeq sales were GBP488 million declining 17% AER, 
  7% CER. In Europe, total sales were GBP292 million with growth of 
  8% AER, 11% CER. New HIV products delivered sales of GBP97 million, 
  including: Dovato GBP69 million growth of more than 100% AER and 
  more than 100% CER and Juluca GBP27 million growth of 29% AER, 38% 
  CER. Combined Tivicay and Triumeq sales were GBP184 million declining 
  17% AER, 14% CER. 
  Oncology 
  Sales of Zejula, the PARP inhibitor treatment for ovarian cancer 
  were GBP98 million in the quarter, up 27% AER, 38% CER. Sales included 
  GBP54 million in the US and GBP41 million in Europe. 
  Blenrep for the treatment of patients with relapsed or refractory 
  multiple myeloma was approved and launched in the US and Europe in 
  Q3 2020 and reported sales of GBP21 million in the quarter. 
  Immuno-inflammation 
  Sales of Benlysta in the quarter were up 21% AER, 34% CER to GBP214 
  million, including the impact of lupus nephritis launches in US and 
  Japan in H2 2020. In the quarter, the first sales of sotrovimab, 
  the monoclonal antibody treatment for COVID-19 patients at risk of 
  hospitalisation totalled GBP16 million. 
  Established Pharmaceuticals 
  Sales of Established Pharmaceuticals in the quarter were GBP1,925 
  million, down 8% AER, but flat at CER. 
  Established Respiratory products declined 2% AER but grew 6% CER 
  to GBP1,089 million. The ongoing impact of generic competition to 
  Xyzal in Japan, and to Advair/Seretide in all regions was more than 
  offset by the favourable impact on growth from destocking last year 
  and the benefit of a prior period RAR adjustment in the quarter. 
  The remainder of the Established Pharmaceuticals portfolio declined 
  by 14% AER, 7% CER to GBP836 million driven by generic impacts including 
  Volibris in Europe and Avolve/Avodart in Japan.

 Vaccines turnover grew 39% AER, 49% CER to GBP1,571 million, primarily 
  driven by pandemic adjuvant sales, higher demand for DTPa-containing 
  vaccines in the US and higher demand for Bexsero in the US and in 
  Europe. 
 
  Vaccines turnover excluding pandemic vaccines grew 16% AER, 24% CER 
  to GBP1,311 million. 
 
  Vaccines performance in Q2 2021 continued to be affected by lower 
  demand for routine adult vaccination due to COVID-19 vaccination 
  programme deployment mainly in the US and Europe. Demand for paediatric 
  and adolescent vaccination improved as lifting of stay-at-home directives 
  resulted in increased visits to healthcare practitioners and points 
  of vaccination. 
 
  Higher demand in the US for paediatric and adolescent vaccination 
  represented a recovery trend including partial catch up of prior 
  period missed vaccinations and CDC purchasing patterns. 
 
  In Q2 2020, sales declined 29% CER due to the significant impact 
  of the COVID-19 pandemic across all regions. 
 
  Meningitis 
  Meningitis sales grew 35% AER, 46% CER to GBP225 million. Bexsero 
  sales grew 53% AER, 63% CER to GBP165 million reflecting higher demand 
  and increased market share in the US, together with strong performance 
  in Europe and International. 
 
  Menveo sales were up 55% AER, 71% CER to GBP59 million, primarily 
  driven by higher demand in the US, partly offset by unfavorable phasing 
  and lower demand in International. 
 
  Influenza 
  Fluarix/FluLaval sales grew by more than 100% AER and CER, to GBP33 
  million driven by strong southern hemisphere demand in International. 
 
  Shingles 
  Shingrix d eclined by 9% AER but grew 1% CER to GBP295 million. 
  Growth from launches in the UK and in China was mostly offset by 
  a decline in Germany where COVID-19 related restrictions and prioritisation 
  of COVID-19 mass vaccination limited Shingrix uptake. In the US, 
  increased market demand in the current quarter was offset by favourable 
  prior period returns and rebates movements and channel stocking in 
  the comparator quarter. 
 
  Established Vaccines 
  Hepatitis vaccines sales were up 28% AER, 38% CER to GBP110 million, 
  largely driven by favourable US wholesaler purchasing patterns and 
  higher demand in paediatric vaccines, partly offset by higher competitive 
  pressure in the US. 
 
  Sales of DTPa-containing vaccines (Infanrix, Pediarix and Boostrix) 
  grew by 45% AER, 55% CER. Infanrix/Pediarix sales rose 14% AER, 24% 
  CER to GBP136 million, reflecting increased channel stock replenishment 
  on wholesaler purchasing patterns and demand in the US , partly offset 
  by a change in recommendation for the dosing schedule in Germany 
  and supply constraints in Europe. Boostrix sales grew 92% AER and 
  more than 100% CER to GBP146 million largely driven by higher demand 
  in the US and in International. 
 
  Rotarix sales were up 3% AER, 9% CER to GBP132 million, reflecting 
  increased channel stocking on wholesaler purchasing patterns in the 
  US. 
 
  Synflorix sales declined by 6% AER, 2% CER to GBP97 million, primarily 
  due to lower tender demand in Emerging Markets and Europe. 
 
  MMRV vaccines sales were flat at AER, but grew 6% CER to GBP54 million, 
  largely driven by favourable phasing in International. 
 
  Pandemic Vaccines 
  Pandemic vaccines sales of GBP260 million included GBP258 million 
  of pandemic adjuvant sales, which represented delivery of around 
  two-thirds of the contracted volumes with the US and Canadian governments.

 Consumer Healthcare sales declined 4% AER, but increased 3% CER to 
  GBP2,292 million in the second quarter with growth in the quarter 
  more than offsetting dilution from the divestment programme which 
  completed at the end of Q1 2021. 
 
  Sales excluding brands divested/under review declined 1% AER but 
  increased 7% CER supported by a favourable comparative in Q2 2020 
  as a result of destocking. In the second quarter last year, sales 
  at CER excluding brands divested/under review were flat at pro-forma 
  and included the reversal of the benefit of the accelerated purchases 
  in the first quarter in 2020 across all categories as a result of 
  the COVID-19 pandemic. Additionally, Q2 2020 benefited by approximately 
  2 percentage points from increased retailer stocking ahead of a systems 
  cutover in North America which reversed in Q3 2020. 
 
  On a 2 year CAGR sales excluding brands divested/under review increased 
  3%. Consistent with disclosure in the Q1 2021 press release given 
  the significant volatility with the Q1 2020 and Q2 2020 comparatives 
  as a result of the COVID-19 pandemic the 2 year category CAGRs are 
  shared below. These are shared for the first half of this year only, 
  as this is more indicative of underlying trends than looking at the 
  quarters in isolation. 
 
  International sales excluding brands divested/under review grew high 
  single digit CER with strong performance in the emerging markets 
  such as China, Latin America, and India. 
  Oral health 
  Oral health sales increased 4% AER, 12% CER to GBP663 million. In 
  Q2 2020 Oral health sales declined low single digit. Sensodyne delivered 
  growth in the mid-teens compared with low single digit growth in 
  Q2 2020, reflecting underlying brand strength and continued innovation 
  particularly in the US, Middle East and Africa and India. Gum health 
  and Denture care reported mid-teens growth and high single digit 
  growth respectively in the second quarter. Denture care sales, whilst 
  up in the quarter helped by a favourable comparative to Q2 2020, 
  continued to be negatively impacted by social distancing due to the 
  pandemic. On a 2 year CAGR growth was 5%, consistent with the 2 year 
  CAGR for the first quarter and similar to trends in the second half 
  of 2020. 
 
  Pain relief 
  Pain relief sales increased 6% AER, 13% CER to GBP563 million. In 
  Q2 2020 Pain relief sales declined low single digit on a pro-forma 
  basis. Advil and Panadol increased double digit helped by favourable 
  comparatives due to destocking in Q2 2020. Voltaren increased low 
  double digit helped by the successful Rx to OTC switch in May last 
  year. The 2 year CAGR for the category grew 5% similar to the 2 year 
  CAGR in the prior quarter. 
  Vitamins, minerals and supplements 
  Vitamins, minerals and supplements sales declined 11% AER, 6% CER 
  to GBP359 million. In Q2 2020 Vitamins, minerals and supplements 
  sales increased high-teens per cent on a pro-forma basis. Centrum 
  grew low single digit although this was more than offset by a double 
  digit decline in Emergen-C which faced particularly challenging comparatives 
  (sales almost doubled in Q2 2020) and a mid-single digit decline 
  in Caltrate. On a 2 year CAGR the category grew 6%. 
  Respiratory health 
  Respiratory health sales declined 2% AER but increased 6% CER to 
  GBP210 million. In Q2 2020 Respiratory health sales declined low 
  double digit on a pro-forma basis. Theraflu and Robitussin declined 
  significantly. Otrivin and Flonase were up double digit although 
  helped by easier comparatives in Q2 2020 when sales declined in the 
  high teens. The category 2 year CAGR declined 3%. Seasonal cold, 
  flu and nasal brands continued to be adversely impacted by the weaker 
  cold and flu season as a result of the pandemic and social distancing, 
  and its 2 year CAGR declined high single digit. In contrast the allergy 
  2 year CAGR was up high single digit. 
  Digestive health and other 
  Digestive health and other brands sales declined 5% AER but increased 
  3% CER at GBP464 million. In Q2 2020 Digestive health and other brands 
  had decreased low-single digits on a pro-forma basis. Digestive health 
  products saw double digit growth, with Smokers health products up 
  mid single digit and Skin health products up high teens although 
  brands such as Chapstick remained muted given reduced impulse purchase. 
  The 2 year category CAGR was flat. 
 
 
 Operating performance 
 
 
 Cost of sales 
  Total cost of sales as a percentage of turnover was 31.6%, 0.6 percentage 
  points lower at AER and 1.8 percentage points lower in CER terms 
  compared with Q2 2020. This included a similar level of write downs 
  in manufacturing sites as in Q2 2020. 
  Excluding these and other Adjusting items, Adjusted cost of sales 
  as a percentage of turnover was 29.0%, 0.5 percentage points lower 
  at AER and 1.6 percentage points lower at CER compared with Q2 2020. 
  This reflected price benefits in Pharmaceuticals, including the benefit 
  from a prior period RAR adjustment, reduced supply chain costs and 
  a favourable mix in Vaccines, including pandemic adjuvants. 
  Selling, general and administration 
  Total SG&A costs as a percentage of turnover were 32.6%, 2.9 percentage 
  points lower at AER and 3.6 percentage points lower at CER compared 
  with Q2 2020. 
  Excluding Adjusting items, Adjusted SG&A costs as a percentage of 
  turnover were 30.9%, 2.3 percentage points lower at AER than in Q2 
  2020 and 3.0 percentage points lower on a CER basis. Adjusted SG&A 
  costs declined 1% AER but increased 5% CER which reflected increased 
  investment for launches in Pharmaceuticals and Vaccines compared 
  to reduced spend in Q2 2020 as a result of the COVID-19 lockdowns 
  partly offset by continued tight control of ongoing costs and the 
  continuing benefit of restructuring in Pharmaceuticals, Consumer 
  Healthcare and support functions. 
  Research and development 
  Total R&D expenditure was GBP1,222 million (15.1% of turnover), down 
  6% AER, but flat at CER, including a decrease in impairments. Adjusted 
  R&D expenditure was GBP1,165 million (14.4% of turnover), 1% lower 
  at AER, 6% higher at CER than in Q2 2020. 
  Pharmaceuticals R&D expenditure was GBP883 million, down 4% AER, 
  up 3% CER, primarily driven by increases in the Specialty portfolio 
  excluding Oncology, offset by a net reduction compared to Q2 2020 
  in Oncology. Efficiency savings continue from the implementation 
  of the One Development programme for Pharmaceuticals and Vaccines 
  as part of the Separation preparation restructuring programme and 
  variable spending as a result of COVID-19 lockdowns. 
  In the Specialty portfolio excluding Oncology there has been an increase 
  in investment, specifically related to our two key COVID-19 treatment 
  programmes (sotrovimab and otilimab) and also in bepirovirsen, the 
  HBV antisense oligonucleotide programme, depemokimab, the anti-IL5 
  for asthma and otilimab for rheumatoid arthritis. There has also 
  been an increase in spend for the early stage non-Oncology research 
  portfolio. In Oncology there is increased investment from the progression 
  of Zejula, Jemperli and NY-ESO, offset by a reduction in spend on 
  Blenrep following successful approval in Q3 2020 and feladilimab 
  following the decision to terminate two studies in April. 
  R&D expenditure in Vaccines was GBP224 million, up 28% AER, 34% CER, 
  reflecting increased investment in meningitis and RSV, partly offset 
  by efficiency savings from the implementation of the One Development 
  programme. R&D expenditure in Consumer Healthcare was GBP58 million. 
  Royalty income 
  Royalty income was GBP77 million (Q2 2020: GBP75 million), up 3% 
  AER, but flat at CER. 
 
 
 Other operating income/(expense) 
  Net other operating expense of GBP76 million (Q2 2020: GBP1,610 million 
  income) primarily reflected accounting charges of GBP101 million 
  (Q2 2020: GBP368 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 GBP125 million (Q2 2020: 
  GBP343 million) for the contingent consideration liability due to 
  Shionogi, primarily as a result of the unwinding of the discount 
  for GBP92 million and a charge for GBP33 million from adjustments 
  to sales forecasts partly offset by updated exchange rate assumptions. 
  This was partly offset by fair value gains on investments and a number 
  of asset disposals. Q2 2020 included the net profit on disposal of 
  the Horlicks and other Consumer brands of GBP2,304 million partly 
  offset by the loss on sale of the shares in Hindustan Unilever of 
  GBP476 million. 
 
 
 Operating profit 
  Total operating profit was GBP1,675 million in Q2 2021 compared with 
  GBP2,850 million in Q2 2020. This primarily reflected an unfavourable 
  comparison to the net profit on disposal of the Horlicks and other 
  Consumer brands of GBP2,304 million partly offset by the related 
  loss on sale of the shares in Hindustan Unilever of GBP476 million. 
  Excluding these and other Adjusting items, Adjusted operating profit 
  was GBP2,158 million, 23% higher than Q2 2020 at AER, 43% higher 
  at CER on a turnover increase of 15% CER. The Adjusted operating 
  margin of 26.7% was 3.7 percentage points higher at AER, and 5.6 
  percentage points higher on a CER basis than in Q2 2020. 
  The increase in Adjusted operating profit primarily reflected leverage 
  from a favourable comparison to destocking in Q2 2020 in Pharmaceuticals 
  and Consumer Healthcare, GBP258 million of pandemic adjuvant sales, 
  increased demand for Meningitis and DTPa-containing Vaccines and 
  a favourable prior period RAR adjustment in Pharmaceuticals, continued 
  tight control of ongoing costs and benefits from continued restructuring 
  across the business. This was partly offset by increased investment 
  behind launches and increased investment in R&D. 
  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 2021 amounted to GBP205 million (Q2 2020: GBP240 
  million). This included cash payments made to Shionogi of GBP203 
  million (Q2 2020: GBP232 million). 
  Adjusted operating profit by business 
  Pharmaceuticals operating profit was GBP1,241 million, up 27% AER, 
  and 46% CER on a turnover increase of 12% CER. The operating margin 
  of 29.3% was 5.6 percentage points higher at AER than in Q2 2020 
  and 7.2 percentage points higher on a CER basis. This primarily reflected 
  positive leverage from a favourable comparison to destocking in Q2 
  2020 and a favourable prior period RAR adjustment, as well as continued 
  tight control of ongoing costs and benefits from continued restructuring. 
  This was partly offset by increased investment in R&D. 
  Vaccines operating profit was GBP514 million, up 94% AER, >100% CER 
  on a turnover increase of 49% CER. The operating margin of 32.7% 
  was 9.3 percentage points higher at AER than in Q2 2020 and 11.4 
  percentage points higher on a CER basis. This was primarily driven 
  by positive operating leverage from sales growth including pandemic 
  adjuvant sales mix. This was partly offset by higher R&D spend to 
  support key strategic priorities along with increased SG&A investment 
  to support business growth. 
 
  Consumer Healthcare operating profit was GBP498 million, down 4% 
  AER but up 5% CER on a turnover increase of 3% CER. The operating 
  margin of 21.7% was 0.1 percentage point lower at AER but 0.5 percentage 
  points higher on a CER basis than in Q2 2020. The margin increase 
  at CER reflected incremental synergy benefits from the Pfizer Joint 
  Venture integration, price increases and leverage from volume growth 
  partially offset by the impact of divestments (1.1 percentage points), 
  increased advertising and promotion investment to resume to pre-COVID-19 
  levels, increased commodity costs and investment into manufacturing 
  sites. 
  Net finance costs 
  Total net finance costs were GBP185 million compared with GBP228 
  million in Q2 2020. Adjusted net finance costs were GBP185 million 
  compared with GBP227 million in Q2 2020. The decrease primarily reflects 
  reduced interest expense from lower debt levels, favourable movements 
  in foreign exchange rates and reduced swap interest expense on foreign 
  currency hedges. 
  Share of after tax profits of associates and joint ventures 
  The share of after tax profits of associates and joint ventures was 
  GBP16 million (Q2 2020: GBP19 million). 
  Loss on disposal of interest in associates 
  In the quarter the net loss on disposal of interest in associates 
  was GBP36 million, primarily driven by a loss on disposal of the 
  interest in Innoviva Inc. 
  Taxation 
  The credit of GBP68 million represented an effective tax rate on 
  Total results of (4.6)% (Q2 2020: 7.6%) and reflected the different 
  tax effects of the various Adjusting items including a credit of 
  GBP325 million in Q2 2021 resulting from the revaluation of deferred 
  tax assets following enactment of the proposed change of UK corporation 
  tax rate from 19% to 25% (effective 1 April 2023). Q2 2020 reflected 
  the disposal of the Horlicks and other Consumer brands and the subsequent 
  disposal of shares received in Hindustan Unilever. Tax on Adjusted 
  profit amounted to GBP366 million and represented an effective Adjusted 
  tax rate of 18.4% (Q2 2020: 20.5%). 
 
  Issues related to taxation are described in Note 14, 'Taxation' in 
  the Annual Report 2020. 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 GBP143 million (Q2 2020: GBP177 million). The reduction was primarily 
  due to a reduced allocation of Consumer Healthcare Joint Venture 
  profits of GBP76 million (Q2 2020: GBP137 million), partly offset 
  by an increased allocation of ViiV Healthcare profits of GBP60 million 
  (Q2 2020: GBP24 million), including reduced credits for re-measurement 
  of contingent consideration liabilities. 
  The allocation of Adjusted earnings to non-controlling interests 
  amounted to GBP216 million (Q2 2020: GBP267 million). The reduction 
  in allocation primarily reflected a reduced allocation of Consumer 
  Healthcare Joint Venture profits of GBP108 million (Q2 2020: GBP138 
  million) and a reduced allocation of ViiV Healthcare profits of GBP101 
  million (Q2 2020: GBP113 million), as well as lower net profits in 
  some of the Group's other entities with non-controlling interests. 
  Earnings per share 
  Total EPS was 27.9p, compared with 45.5p in Q2 2020. This primarily 
  reflected an unfavourable comparison to the net profit on disposal 
  in Q2 2020 of the Horlicks and other Consumer brands partly offset 
  by the related loss on sale of the shares in Hindustan Unilever, 
  as well as by a credit of GBP325 million to Taxation in Q2 2021 resulting 
  from the revaluation of deferred tax assets following enactment of 
  the proposed change of UK corporation tax rate from 19% to 25% (effective 
  1 April 2023). 
  Adjusted EPS was 28.1p compared with 19.2p in Q2 2020, up 46% AER 
  and 71% CER, on a 43% CER increase in Adjusted operating profit reflecting 
  sales increases in Pharmaceuticals and Consumer Healthcare including 
  a benefit from destocking in Q2 2020 and increased Vaccines sales 
  including pandemic adjuvant sales, lower interest costs, a lower 
  effective tax rate and a lower non-controlling interest allocation 
  of Consumer Healthcare and ViiV profits. The contribution to growth 
  from COVID-19 solutions was approximately 20% AER, 21% CER. 
  Currency impact on Q2 2021 results 
  The results for Q2 2021 are based on average exchange rates, principally 
  GBP1/$1.40, GBP1/EUR1.16 and GBP1/Yen 152. Comparative exchange rates 
  are given on page 59. The period-end exchange rates were GBP1/$1.39, 
  GBP1/EUR1.17 and GBP1/Yen 153. 
  In the quarter, turnover increased 6% AER, 15% CER. Total EPS was 
  27.9p compared with 45.5p in Q2 2020. Adjusted EPS was 28.1p compared 
  with 19.2p in Q2 2020, up 46% AER and 71% CER. The adverse currency 
  impact primarily reflected the strengthening in Sterling, particularly 
  against the US as well as Yen. Exchange gains or losses on the settlement 
  of intercompany transactions had a 1% impact on the negative currency 
  impact of 25 percentage points 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 Q2 2021 were GBP138 
  million (Q2 2020: GBP193 million), analysed as follows:

 Cash charges of GBP104 million under the Separation Preparation programme 
  primarily arose from restructuring of some administrative functions 
  as well as commercial pharmaceuticals and R&D functions. Non-cash 
  credits of GBP10 million primarily reflected a write back on disposal 
  of a site. 
  Cash charges of GBP35 million on the Consumer Healthcare Joint Venture 
  programme primarily related to severance and integration costs. 
  Total cash payments made in Q2 2021 were GBP197 million (Q2 2020: 
  GBP163 million), GBP114 million (Q2 2020: GBP20 million) relating 
  to the Separation Preparation restructuring programme, a further 
  GBP48 million (Q2 2020: GBP65 million) relating to the Consumer Healthcare 
  Joint Venture integration programme, GBP21 million (Q2 2020: GBP47 
  million) under the 2018 major restructuring programme including the 
  settlement of certain charges accrued in previous quarters and GBP14 
  million (Q2 2020: GBP31 million) for the existing Combined restructuring 
  and integration programme.

 The benefit in the quarter from restructuring programmes was GBP0.1 
  billion, with contributions from the Consumer Healthcare Joint Venture 
  integration and the Separation Preparation restructuring programme. 
 
 
 Transaction-related adjustments 
  Transaction-related adjustments resulted in a net charge of GBP130 
  million (Q2 2020: GBP349 million). This included a net GBP101 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 GBP125 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 the unwind of the discount 
  for GBP92 million and a charge of GBP33 million primarily from adjustments 
  to sales forecasts partly offset by updated exchange rate assumptions. 
  The GBP37 million credit relating to the ViiV Healthcare put option 
  and Pfizer preferential dividends represented a reduction in the 
  valuation of the put option primarily as a result of lower cash following 
  preference dividend payments. 
  The ViiV Healthcare contingent consideration liability is fair valued 
  under IFRS. The potential impact of the COVID-19 pandemic remains 
  uncertain and at 30 June 2021, 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 also included fair value gains on investments 
  and a number of asset disposals and certain other Adjusting items, 
  including the impact of the proposed change of UK Corporation tax 
  rate as discussed on page 11. In the quarter, the net loss on disposal 
  of interests in associates was GBP36 million, primarily driven by 
  a loss on disposal of the interest in Innoviva Inc. There was a credit 
  of GBP11 million (Q2 2020: GBP1 million charge) for significant legal 
  matters arising in the quarter. Significant legal cash payments were 
  GBP1 million (Q2 2020: GBP1 million). 
  Separation costs 
  From Q2 2020, the Group started to report additional costs to prepare 
  for Consumer Healthcare separation. Separation costs incurred in 
  the quarter were GBP74 million (Q2 2020: GBP18 million).

 Pharmaceuticals turnover in the six months was GBP8,111 million, 
  down 5% AER but up 2% CER with Sterling strengthening over the period. 
  HIV sales were down 5% AER but up 1% CER, to GBP2,266 million, with 
  growth in Juluca and Dovato partly offset by Tivicay and Triumeq. 
  Respiratory sales were up 22% AER, 31% CER, to GBP1,336 million, 
  on growth of Trelegy and Nucala. Sales of Established Pharmaceuticals 
  declined 15% AER, 9% CER to GBP3,867 million. 
  In the first half of last year, the additional COVID-19 related demand 
  experienced towards the end of the first quarter was broadly reversed 
  in the second quarter. In the current year, the market environment 
  continues to be impacted by COVID-19, impacting our Established Pharmaceuticals 
  products in International and Europe regions. 
  In the US, sales grew 4% AER, 14% CER with continued growth of New 
  and Specialty products supplemented by growth in Established Products. 
  This reflected strong demand for Established Respiratory products 
  in the COVID-19 environment and certain supply challenges faced by 
  generic competitor products, plus the benefit of a favourable prior 
  period RAR adjustment. 
  In Europe, sales declined 8% AER and 7% CER, with growth of Trelegy, 
  Nucala, Benlysta and Oncology products offset by declines in the 
  Established Pharmaceuticals portfolio. This portfolio was impacted 
  by generic competition including Seretide, Duodart and Volibris, 
  lower antibiotic demand, and a one-off UK Relenza contract last year. 
  Growth in HIV two-drug regimens was offset by declines in Tivicay 
  and Triumeq. 
  International declined 13% AER, 6% CER. Growth from the Respiratory 
  and HIV portfolios was offset by declines in Established Pharmaceuticals 
  which continued to be impacted by COVID-19 suppressed antibiotics 
  markets and increased generic competition in Japan on Xyzal and Avolve. 
  Respiratory 
  Total Respiratory sales were up 22% AER, 31% CER, with strong growth 
  from all Regions. International Respiratory sales grew 37% AER, 45% 
  CER including Nucala up 24% AER, 34% CER, and Trelegy up 94% AER 
  and more than 100% CER including the impact of Trelegy Asthma launched 
  in Japan in Q4 2020. In Europe, Respiratory grew 12% AER, 12% CER 
  with double digit growth of Trelegy and high single digit growth 
  of Nucala. In the US, Respiratory grew 23% AER, 35% CER, driven by 
  Trelegy and Nucala and the impact of a prior period RAR adjustment. 
  Sales of Nucala were GBP546 million in the six months and grew 21% 
  AER, 29% CER, with consistent, strong growth across all three regions. 
  US sales were up 25% AER, 37% CER to GBP332 million and International 
  sales of GBP87 million grew 24% AER, 34% CER. Europe sales of GBP127 
  million grew 9% AER, 9% CER. 
  Trelegy sales were up 39% AER, 49% CER to GBP539 million driven by 
  growth in all regions. In the US, sales benefited from the new asthma 
  indication approved and launched in Q3 2020, with sales up 38% AER, 
  51% CER. In Europe, sales grew 21% AER, 21% CER and in International, 
  where Trelegy asthma was approved in Japan in Q4 2020, sales grew 
  94% AER and more than 100% CER to GBP68 million. 
  HIV 
  HIV sales were GBP2,266 million with decline of 5% AER but growth 
  of 1% CER in the six months. Triumeq sales were GBP902 million, down 
  21% AER, 16% CER and Tivicay sales were GBP708 million, down 10% 
  AER, 3% CER. In the first six months, growth was reduced by customer 
  stock building due to COVID-19 in 2020, mainly in the US and Europe, 
  accounting for 1 percentage point of CER growth. The mature portfolio 
  drove 1 percentage point of CER decline. 
  New HIV products Juluca, Dovato, Rukobia and Cabenuva delivered sales 
  of GBP592 million representing 26% of the total HIV portfolio. Sales 
  of the two drug regimens Juluca and Dovato were GBP244 million and 
  GBP325 million, respectively, with combined growth of 55% AER, 65% 
  CER. Rukobia sales were GBP17 million. Cabenuva, the first long acting 
  injectable, recorded half year sales of GBP6 million. 
  In the US, total sales were GBP1,313 million with decline of 9% AER 
  and 1% CER. New HIV products delivered sales of GBP382 million, including: 
  Dovato GBP176 million growth of 87% AER and more than 100% CER, Juluca 
  GBP184 million flat at AER, but growth of 9% CER, Rukobia GBP17 million 
  and Cabenuva GBP5 million. Combined Tivicay and Triumeq sales were 
  GBP907 million declining 20% AER, 13% CER. In Europe, total sales 
  were GBP579 million with decline of 2% AER, 2% CER. New HIV products 
  delivered sales of GBP181 million, including: Dovato GBP127 million 
  growth of more than 100% AER and more than 100% CER and Juluca GBP53 
  million growth of 18% AER, 20% CER. Combined Tivicay and Triumeq 
  sales were GBP380 million declining 21% AER, 21% CER. 
  Oncology 
  Sales of Zejula, the PARP inhibitor treatment for ovarian cancer 
  were GBP186 million, up 18% AER, 24% CER. Sales included GBP105 million 
  in the US and GBP77 million in Europe. 
  Blenrep for the treatment of patients with relapsed or refractory 
  multiple myeloma was approved and launched in the US and Europe in 
  Q3 2020. Launches in Europe included four markets in the first half 
  of the year, and sales globally totalled GBP42 million. 
  Immuno-inflammation 
  Sales of Benlysta were up 20% AER, 30% CER to GBP392 million, including 
  the impact of lupus nephritis launches in US and Japan in H2 2020. 
  The first sales of sotrovimab, the monoclonal antibody treatment 
  for COVID-19 patients at risk of hospitalisation, totalled GBP16 
  million. 
  Established Pharmaceuticals 
  Sales of Established Pharmaceuticals in the six months were GBP3,867 
  million, down 15% AER, 9% CER. 
  Established Respiratory products declined 9% AER 3% CER to GBP2,216 
  million. This reflects the ongoing impact of generic competition 
  to Xyzal in Japan, and to Advair/Seretide globally. The decline was 
  partially offset by the favourable impact on growth of favourable 
  prior period RAR adjustments. 
  The remainder of the Established Pharmaceuticals portfolio declined 
  by 21% AER, 16% CER to GBP1,651 million on lower demand for antibiotics 
  during the COVID-19 pandemic period, the impact of government mandated 
  changes increasing use of generics in markets including France, Japan 
  and China and a strong comparator, including the European Relenza 
  contract.

 Vaccines turnover declined 5% AER, but was flat at CER to GBP2,795 
  million, primarily driven by pandemic adjuvant sales, offset by the 
  adverse impact of the COVID-19 pandemic on Shingrix. 
 
  Vaccines turnover excluding pandemic vaccines declined 14% AER, 9% 
  CER to GBP2,535 million. 
 
  Vaccines performance in the first half of 2021 was affected by lower 
  demand for routine adult vaccination due to COVID-19 vaccination 
  programme deployment mainly in the US and Europe, resulting in lower 
  Shingrix sales. Demand for paediatric and adolescent vaccination 
  improved, particularly in the second quarter, as lifting of stay-at-home 
  directives resulted in increased visits to healthcare practitioners 
  and points of vaccination. 
 
  Higher demand in the US for paediatric and adolescent vaccination 
  represents a recovery trend related to improved COVID-19 pandemic 
  conditions. 
 
  In the comparator period, vaccines sales declined by 6% CER primarily 
  driven by the adverse impact of the COVID-19 pandemic in the second 
  quarter. 
 
  Meningitis 
  Meningitis sales grew 6% AER, 12% CER to GBP415 million. Bexsero 
  sales grew 10% AER, 15% CER to GBP299 million, reflecting higher 
  demand together with increased market share in the US and strong 
  performance in Europe. 
 
  Menveo sales were up 26% AER, 36% CER to GBP98 million, primarily 
  driven by higher demand and increased market share in the US. 
 
  Influenza 
  Fluarix/FluLaval sales grew 42% AER, 53% CER, to GBP51 million driven 
  by higher southern hemisphere demand in International. 
 
  Shingles 
  Shingrix declined by 36% AER, 31% CER to GBP622 million, primarily 
  driven by lower demand in the US due to prioritised focus on COVID-19 
  mass vaccination of older adults together with US channel stocking 
  and favourable prior period returns and rebates movements in the 
  comparator period. Growth from launches in the UK and in China was 
  mostly offset by a decline in Germany and in Canada where COVID-19 
  related restrictions and prioritisation of COVID-19 mass vaccination 
  limited Shingrix uptake. 
 
  Established Vaccines 
  Hepatitis vaccines were down 31% AER, 27% CER to GBP205 million, 
  adversely impacted in the US and Europe by lower demand due to COVID-19 
  pandemic conditions, travel restrictions in Europe and competitive 
  pressure in the US market. 
 
  Sales of DTPa-containing vaccines (Infanrix, Pediarix and Boostrix) 
  grew by 5% AER, 11% CER. Infanrix/Pediarix sales declined 9% AER, 
  3% CER to GBP272 million, reflecting supply constraints and lower 
  tender demand in Europe together with the change in recommendation 
  for the dosing schedule in Germany, partly offset by increased channel 
  stock replenishment on wholesaler purchasing patterns and demand 
  in the US. Boostrix sales grew 28% AER, 34% CER to GBP240 million, 
  largely driven by higher demand in International together with favourable 
  US wholesaler purchasing patterns and higher demand. 
 
  Rotarix sales were down 12% AER, 8% CER to GBP246 million, reflecting 
  unfavourable phasing in Emerging Markets. 
 
  Synflorix sales declined by 12% AER, 10% CER to GBP199 million, 
  primarily due to lower tender demand in Emerging Markets and Europe. 
 
  MMRV vaccines sales grew 5% AER, 9% CER to GBP117 million, largely 
  driven by improved supply in International. 
 
  Pandemic Vaccines 
  Pandemic vaccines sales of GBP260 million included GBP258 million 
  of pandemic adjuvant sales, which represented delivery of around

 Consumer Healthcare sales for the six months sales declined 12% AER, 
  7% CER to GBP4,604 million largely driven by the divestment programme 
  which completed in Q1 2021 as well as the H1 2020 comparative including 
  a particularly strong first quarter given accelerated purchasing 
  due to the COVID-19 pandemic. 
 
  Sales excluding brands divested/under review declined 2% CER, which 
  compares to the same six months last year when sales increased 7% 
  CER excluding brands divested/under review on a pro-forma basis. 
  In addition to benefitting from the particularly strong first quarter 
  last year, H1 2020 was helped by 1 percentage point from the increased 
  retailer stocking ahead of a systems cutover in North America, which 
  subsequently reversed in the third quarter of 2020. Consistent with 
  the Q2 2021 results, the first half 2 year CAGRs are shared below, 
  to give more perspective on underlying performance trends adjusting 
  for the volatility in the first two quarters last year as a result 
  of the pandemic. The unprecedented negative impact of a historically 
  weak seasonal cold flu and nasal products continued to adversely 
  impact sales growth. 
 
  International sales excluding brands divested/under review grew high 
  single digit CER in emerging markets, with double digit growth in 
  China, Latin America, India and high single digit growth in Middle 
  East and Africa. 
  Oral health 
  Oral health sales decreased 1% AER and increased 5% CER to GBP1,358 
  million. In H1 2020 Oral health sales increased mid single digit. 
  Sensodyne delivered high single digit growth reflecting underlying 
  brand strength, continued innovation and good consumer up take in 
  traditional retail and ecommerce channels particularly in India and 
  in the US. Gum health delivered double digit growth, whilst Denture 
  care was flat. On a 2 year CAGR growth for the category was up 5%. 
 
  Pain relief 
  Pain relief sales decreased 3% AER and increased 2% CER to GBP1,109 
  million. In H1 2020, Pain relief sales increased mid single digit 
  on a pro-forma basis. Advil declined in the high teens (compared 
  to double digit growth in H1 2020) which was more than offset mainly 
  by growth in the mid-teens for Voltaren and to a lesser extent by 
  Panadol which was up low single digit. Voltaren growth was helped 
  by the successful Rx to OTC switch in the US last year. On a 2 year 
  CAGR growth for the category was up 4%. 
  Vitamins, minerals and supplements 
  Vitamins, minerals and supplements sales declined 8% AER, 4% CER 
  to GBP708 million. In H1 2020 Vitamins, minerals and supplements 
  sales increased high-teens per cent on a pro-forma basis. Caltrate 
  delivered double digit growth and Centrum grew low single digit (compared 
  with growth in the high teens in H1 2020) although this was more 
  than offset by double digit decline in Emergen-C which faced a particularly 
  challenging comparator in H1 2020 when volumes almost doubled. On 
  a 2 year CAGR the growth for the category was up 7%. 
  Respiratory health 
  Respiratory health sales declined 31% AER, 26% CER to GBP453 million. 
  In H1 2020, Respiratory health sales increased low double digit on 
  a pro-forma basis benefiting from accelerated purchasing in the first 
  quarter particularly on cold and flu products. Theraflu and Robitussin 
  declined double digit given the continued impact of a significantly 
  lower cold and flu season due to the COVID-19 pandemic and social 
  distancing and a strong H1 2020 comparator. Otrivin declined double 
  digit and Flonase was flat. On a 2 year CAGR the category was down 
  10%, with seasonal cold, flu and nasal down mid-teens and allergy 
  up low single digit. 
  Digestive health and other 
  Digestive health and other brands sales decreased 5% AER and increased 
  2% CER at GBP892 million. In H1 2020, Digestive health and other 
  brands declined low-single digits on a pro-forma basis. Growth in 
  Digestive health products offset a decline Smokers' health products, 
  with Skin health products up low single digit. On a 2 year CAGR the 
  growth for the category was flat. 
 
 
 Operating performance 
 
 
 Cost of sales 
  Total cost of sales as a percentage of turnover was 32.5%, 1.3 percentage 
  points lower at AER and 2.4 percentage points lower in CER terms 
  compared with H1 2020. This primarily reflected lower write downs 
  in a number of manufacturing sites and the unwind in Q1 2020 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 29.6%, 0.5 percentage points higher 
  at AER but 0.4 percentage points lower at CER compared with H1 2020. 
  This reflected price benefits in Pharmaceuticals, including the benefit 
  from a prior period RAR adjustment, as well as reduced supply chain 
  costs partly offset by an adverse mix in Vaccines, primarily due 
  to the reduction in Shingrix sales in the US partly offset by beneficial 
  pandemic adjuvant mix, as well as higher supply chain costs and under-recoveries 
  resulting from lower demand. 
  Selling, general and administration 
  Total SG&A costs as a percentage of turnover were 32.7%, 1.0 percentage 
  points lower at AER and 1.6 percentage points lower at CER compared 
  with H1 2020. 
  Excluding Adjusting items, Adjusted SG&A costs as a percentage of 
  turnover were 31.0%, 0.8 percentage points lower at AER than in H1 
  2020 and 1.3 percentage points lower on a CER basis. Adjusted SG&A 
  costs declined 9% AER, 6% CER which reflected the tight control of 
  ongoing costs and reduced variable spending across all three businesses 
  as a result of the COVID-19 lockdowns, and the continuing benefit 
  of restructuring in Pharmaceuticals, Consumer Healthcare and support 
  functions. Over a third of this decline also reflected a favourable 
  legal settlement in H1 2021 compared to increased legal costs in 
  2020. 
  Research and development 
  Total R&D expenditure was GBP2,340 million (15.1% of turnover), down 
  6% AER, 1% CER, including a decrease in major restructuring charges 
  and impairments. Adjusted R&D expenditure was GBP2,242 million (14.5% 
  of turnover), 1% lower at AER, 5% higher at CER than in H1 2020. 
  Pharmaceuticals R&D expenditure was GBP1,717 million, down 3% AER, 
  up 3% CER, primarily driven by the increased investment in our Specialty 
  portfolio offset by a net reduction in Oncology. Efficiency savings 
  continued from the implementation of the One Development programme 
  for Pharmaceuticals and Vaccines as part of the Separation Preparation 
  restructuring programme and variable spending as a result of COVID-19 
  lockdowns. 
  The growth of the Specialty portfolio excluding Oncology investment 
  was driven primarily by our two COVID-19 treatment programmes (sotrovimab 
  and otilimab) as well as the progression of a number of other key 
  programmes, including bepirovirsen, the HBV antisense oligonucleotide 
  programme, depemokimab, the anti-IL5 for asthma and otilimab for 
  rheumatoid arthritis. In Oncology there has been increased investment 
  in Zejula and Jemperli, offset by a reduction in spend on Blenrep 
  following successful approval in Q3 2020 and feladilimab following 
  the decision to terminate two studies in April. 
  R&D expenditure in Vaccines was GBP412 million, up 24% AER, 26% CER, 
  reflecting increased investment in clinical programmes for meningitis 
  ABCWY and RSV, partly offset by efficiency savings from the implementation 
  of the One Development programme and variable spending as a result 
  of COVID-19 lockdowns. R&D expenditure in Consumer Healthcare was 
  GBP113 million. 
  Royalty income 
  Royalty income was GBP168 million (H1 2020: GBP142 million), up 18% 
  AER, 18% CER, primarily driven by higher sales of Gardasil. 
 
 
 Other operating income/(expense) 
  Net other operating income of GBP133 million (H1 2020: GBP1,769 million 
  income) primarily reflected a number of asset disposals including 
  the disposal of royalty rights on cabozantinib, disposal of a number 
  of Consumer brands and fair value uplifts on investments partly offset 
  by accounting charges of GBP208 million (H1 2020: GBP841 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 GBP259 
  million (H1 2020: GBP778 million) for the contingent consideration 
  liability due to Shionogi, primarily as a result of the unwinding 
  of the discount for GBP185 million and a charge for GBP74 million 
  from adjustments to sales forecasts partly offset by updated exchange 
  rate assumptions. H1 2020 included the net profit on disposal of 
  the Horlicks and other Consumer Healthcare brands of GBP2,815 million, 
  partly offset by the related loss on sale of the shares in Hindustan 
  Unilever of GBP476 million. 
 
 
 Operating profit 
  Total operating profit was GBP3,368 million in H1 2021 compared with 
  GBP4,864 million in H1 2020. This primarily reflected an unfavourable 
  comparison to the net profit on disposal in Q2 2020 of the Horlicks 
  and other Consumer brands and resultant sale of shares in Hindustan 
  Unilever. This was partly offset by lower major restructuring costs, 
  lower re-measurement charges on the contingent consideration liabilities 
  and the unwind in 2020 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 operating profit 
  was GBP4,039 million, 9% lower than H1 2020 at AER, but 3% higher 
  at CER on a turnover decline of 1% CER. The Adjusted operating margin 
  of 26.0% was 0.4 percentage points lower at AER, but 1.1 percentage 
  points higher on a CER basis than in H1 2020. 
  The increase in Adjusted operating profit primarily reflected the 
  benefit from incremental pandemic adjuvant sales, sales growth in 
  Pharmaceuticals and tight control of ongoing costs including reduced 
  promotional and variable spending across all three businesses as 
  a result of the COVID-19 lockdowns, favourable legal settlements 
  compared to increased legal costs in 2020 and benefits from continued 
  restructuring across the business. This was partly offset by lower 
  non-pandemic sales in Vaccines, primarily Shingrix, an adverse mix 
  in Vaccines as well as higher supply chain costs and under-recoveries, 
  divestments in Consumer Healthcare and increased investment in R&D 
  across Vaccines and Pharmaceuticals. 
  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 2021 amounted to GBP426 million (H1 2020: GBP455 
  million). This included cash payments made to Shionogi of GBP419 
  million (H1 2020: GBP445 million). 
  Adjusted operating profit by business 
  Pharmaceuticals operating profit was GBP2,360 million, up 9% AER, 
  22% CER on a turnover increase of 2% CER. The operating margin of 
  29.1% was 3.7 percentage points higher at AER than in H1 2020 and 
  5.0 percentage points higher on a CER basis. This primarily reflected 
  price benefits in Pharmaceuticals, including the benefit from a prior 
  period RAR adjustment, as well as reduced supply chain costs, the 
  tight control of ongoing costs, reduced variable spending as a result 
  of the COVID-19 lockdowns, a favourable legal settlement in 2021 
  compared to increased legal costs in 2020 and the continuing benefit 
  of restructuring. This was partly offset by increased investment 
  in R&D. 
  Vaccines operating profit was GBP820 million, down 27% AER, 17% CER 
  on flat turnover at CER. The operating margin of 29.3% was 8.9 percentage 
  points lower at AER than in H1 2020 and 6.7 percentage points lower 
  on a CER basis. This was primarily driven by higher supply chain 
  costs resulting from lower demand and adverse mix due to Shingrix 
  sales in the US, along with higher R&D spend to support key strategic 
  priorities. This was partly offset by pandemic adjuvant beneficial 
  mix and higher royalty income. 
  Consumer Healthcare operating profit was GBP1,033 million, down 20% 
  AER, 13% CER on a turnover decrease of 7% CER. The operating margin 
  of 22.4% was 2.1 percentage points lower at AER and 1.4 percentage 
  points lower on a CER basis than in H1 2020. This primarily reflected 
  the impact of divestments (1.7 percentage points), increased advertising 
  and promotion investment to resume pre-COVID-19 levels and increased 
  commodity costs and investment into manufacturing sites, partially 
  offset by synergy benefits from the Pfizer Joint Venture integration, 
  price increases and tight cost control. 
  Net finance costs 
  Total net finance costs were GBP376 million compared with GBP416 
  million in H1 2020. Adjusted net finance costs were GBP375 million 
  compared with GBP414 million in H1 2020. The decrease is primarily 
  as a result of reduced interest expense from lower debt levels and 
  favourable movements in foreign exchange rates, partly offset by 
  an adverse comparison to a fair value gain on interest rate swaps 
  in the 2020 comparator and lower interest income on overseas cash 
  post-closing of the divestment of Horlicks and other Consumer Healthcare 
  nutrition products in India and a number of other countries. 
  Share of after tax profits of associates and joint ventures 
  The share of after tax losses of associates and joint ventures was 
  GBP32 million (H1 2020: GBP28 million profits). 
  Loss on disposal of interest in associates 
  The net loss on disposal of interests in associates was GBP36 million, 
  primarily driven by a loss of disposal of our interest in the associate 
  Innoviva Inc. 
  Taxation 
  The charge of GBP190 million represented an effective tax rate on 
  Total results of 6.4% (H1 2020: 8.0%) and reflected the different 
  tax effects of the various Adjusting items, including a credit of 
  GBP325 million in Q2 2021 resulting from the revaluation of deferred 
  tax assets following enactment of the proposed change of UK corporation 
  tax rate from 19% to 25% (effective 1 April 2023). H1 2020 reflected 
  the disposal of the Horlicks and other Consumer brands and the subsequent 
  disposal of shares received in Hindustan Unilever. Tax on Adjusted 
  profit amounted to GBP684 million and represented an effective Adjusted 
  tax rate of 18.5% (H1 2020: 16.3%). 
  Issues related to taxation are described in Note 14, 'Taxation' in 
  the Annual Report 2020. 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 GBP330 million (H1 2020: GBP291 million). The increase was primarily 
  due to an increased allocation of ViiV Healthcare profits of GBP136 
  million (H1 2020: GBP64 million), including reduced credits for re-measurement 
  of contingent consideration liabilities, partly offset by a reduced 
  allocation of Consumer Healthcare Joint Venture profits of GBP163 
  million (H1 2020: GBP196 million). 
  The allocation of Adjusted earnings to non-controlling interests 
  amounted to GBP462 million (H1 2020: GBP549 million). The reduction 
  in allocation primarily reflected a reduced allocation of Consumer 
  Healthcare Joint Venture profits of GBP222 million (H1 2020: GBP277 
  million) and a reduced allocation of ViiV Healthcare profits of GBP209 
  million (H1 2020: GBP241 million). 
  Earnings per share 
  Total EPS was 49.4p, compared with 77.0p in H1 2020. This primarily 
  reflected an unfavourable comparison to the net profit on disposal 
  in Q2 2020 of the Horlicks and other Consumer brands partly offset 
  by the related loss on sale of the shares in Hindustan Unilever, 
  as well as by a credit of GBP325 million to Taxation in Q2 2021 resulting 
  from the revaluation of deferred tax assets following enactment of 
  the proposed change of UK corporation tax rate from 19% to 25% (effective 
  1 April 2023), lower major restructuring costs and lower re-measurement 
  charges on the contingent consideration liabilities. 
  Adjusted EPS was 51.0p compared with 56.9p in H1 2020, down 10% AER 
  but up 2% CER, on a 3% CER increase in Adjusted operating profit 
  reflecting incremental pandemic adjuvant sales, sales increases in 
  Pharmaceuticals, tight cost control and favourable legal settlements, 
  lower interest costs and a lower non-controlling interest allocation 
  of Consumer Healthcare and ViiV profits, partly offset by lower non-pandemic 
  sales in Vaccines, primarily Shingrix and a higher effective tax 
  rate. The contribution to growth from COVID-19 solutions was approximately 
  7% AER, 7% CER. 
  Currency impact on H1 2021 results 
  The results for H1 2021 are based on average exchange rates, principally 
  GBP1/$1.39, GBP1/EUR1.15 and GBP1/Yen 149. Comparative exchange rates 
  are given on page 59. The period-end exchange rates were GBP1/$1.39, 
  GBP1/EUR1.17 and GBP1/Yen 153. 
  In the six months, turnover decreased 7% AER, 1% CER. Total EPS was 
  49.4p compared with 77.0p in H1 2020. Adjusted EPS was 51.0p compared 
  with 56.9p in H1 2020, down 10% AER but up 2% CER. The adverse currency 
  impact primarily reflected the strengthening in Sterling, particularly 
  against the US Dollar as well as the Japanese Yen. Exchange gains 
  or losses on the settlement of intercompany transactions had a negligible 
  impact on the negative currency impact of twelve percentage points 
  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 2021 were GBP248

 Cash charges of GBP183 million under the Separation Preparation programme 
  primarily arose from restructuring of some administrative and central 
  manufacturing functions as well as commercial pharmaceuticals and 
  R&D functions. 
  Cash charges of GBP75 million on the Consumer Healthcare Joint Venture 
  programme primarily related to severance and integration costs. The 
  non-cash credit in the Combined restructuring and integration programme 
  primarily reflected a write back on disposal of a site. 
  Total cash payments made in H1 2021 were GBP408 million (H1 2020: 
  GBP331 million), GBP214 million (H1 2020: GBP31 million) relating 
  to the Separation Preparation restructuring programme, a further 
  GBP108 million (H1 2020: GBP135 million) relating to the Consumer 
  Healthcare Joint Venture integration programme, GBP54 million (H1 
  2020: GBP100 million) under the 2018 major restructuring programme 
  including the settlement of certain charges accrued in previous quarters 
  and GBP32 million (H1 2020: GBP65 million) for the existing Combined 
  restructuring and integration programme.

  The 2018 major restructuring programme, including Tesaro, is now 
  expected to cost GBP1.6 billion to the end of 2021, with cash costs 
  of GBP0.7 billion and non-cash costs of GBP0.9 billion, and is expected 
  to deliver annual savings of around GBP0.45 billion by the end of 
  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 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 expected to be GBP0.1 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 now expects to deliver GBP0.8 billion of annual savings 
  by 2022 and GBP1.0 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 delivered and 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 GBP246 
  million (H1 2020: GBP918 million). This included a net GBP208 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 GBP259 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 the unwind of the discount 
  for GBP185 million and a charge of GBP74 million primarily from adjustments 
  to sales forecasts partly offset by updated exchange rate assumptions. 
  The GBP90 million credit relating to the ViiV Healthcare put option 
  and Pfizer preferential dividends represented a reduction in the 
  valuation of the put option as a result of lower cash following preference 
  dividend payments and updated exchange rate assumptions. 
  The ViiV Healthcare contingent consideration liability is fair valued 
  under IFRS. The potential impact of the COVID-19 pandemic remains 
  uncertain and at 30 June 2021, 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 also included gains from a number of 
  asset disposals, including the disposal of royalty rights on cabozantinib 
  and disposal of a number of Consumer brands, fair value gains on 
  investments and certain other Adjusting items. The Consumer Brands 
  disposal programme is complete and has delivered net proceeds of 
  GBP1.1 billion. In Q2 2021 the net loss on disposal of interests 
  in associates was GBP36 million, primarily driven by a loss on disposal 
  of the interest in the associate Innoviva Inc. A credit of GBP12 
  million (H1 2020: GBP6 million charge) was recorded for significant 
  legal matters arising in the quarter. Significant legal cash payments 
  were GBP2 million (H1 2020: GBP6 million). 
  Separation costs 
  From Q2 2020, the Group started to report additional costs to prepare 
  for Consumer Healthcare separation. Separation costs incurred in 
  H1 2021 were GBP109 million (H1 2020: GBP18 million). Separation 
  costs incurred to date were GBP177 million. Total separation costs 
  are estimated to be GBP600-700 million, excluding transaction costs.

 Q2 2021 
  The net cash inflow from operating activities for the quarter was 
  GBP1,292 million (Q2 2020: GBP2,760 million). The decrease primarily 
  reflected an adverse comparison to the significant reduction in trade 
  receivables in Q2 2020 as a result of collections following strong 
  sales in Q1 2020, adverse timing of returns and rebates and taxes 
  compared to Q2 2020, partly offset by increased operating profit 
  net of adverse exchange and a lower seasonal increase in inventory. 
  Total cash payments to Shionogi in relation to the ViiV Healthcare 
  contingent consideration liability in the quarter were GBP203 million 
  (Q2 2020: GBP232 million), of which GBP177 million was recognised 
  in cash flows from operating activities and GBP26 million was recognised 
  in contingent consideration paid within investing cash flows. These 
  payments are deductible for tax purposes. 
  Free cash inflow was GBP316 million for the quarter (Q2 2020: GBP1,949 
  million inflow). The decrease primarily reflected an adverse comparison 
  to the significant reduction in trade receivables in Q2 2020 as a 
  result of collections following strong sales in Q1 2020, adverse 
  timing of returns and rebates and taxes compared to Q2 2020, increased 
  purchases of intangible assets and reduced proceeds from intangible 
  assets as the Consumer Brands Disposal programme is now complete. 
  This was partly offset by increased operating profit, a lower seasonal 
  increase in inventory and lower dividends to non-controlling interests. 
 
 
 H1 2021 
  The net cash inflow from operating activities for the six months 
  was GBP1,623 million (H1 2020: GBP3,725 million). The decrease primarily 
  reflected adverse exchange impacts, reduction in trade receivables 
  in H1 2020 as a result of collections following strong sales in Q1 
  2020, adverse timing of returns and rebates and taxes compared to 
  Q2 2020 and increased inventory, partly offset by increased operating 
  profit. 
  Total cash payments to Shionogi in relation to the ViiV Healthcare 
  contingent consideration liability in the six months were GBP419 
  million (H1 2020: GBP445 million), of which GBP366 million was recognised 
  in cash flows from operating activities and GBP53 million was recognised 
  in contingent consideration paid within investing cash flows. These 
  payments are deductible for tax purposes. 
  Free cash inflow was GBP313 million for the six months (H1 2020: 
  GBP2,480 million inflow). The decrease primarily reflected adverse 
  exchange impacts, reduction in trade receivables in H1 2020 as a 
  result of collections following strong sales in Q1 2020, adverse 
  timing of returns and rebates and taxes compared to Q2 2020 increased 
  inventory, increased purchases of intangible assets and reduced proceeds 
  from intangible assets as the Consumer Brands Disposal programme 
  is now complete. This was partly offset by increased operating profit 
  and lower dividends to non-controlling interests. 
 
 
 Net debt 
  At 30 June 2021, net debt was GBP21.9 billion, compared with GBP20.8 
  billion at 31 December 2020, comprising gross debt of GBP25.5 billion 
  and cash and liquid investments of GBP3.6 billion. Net debt increased 
  due to the dividends paid to shareholders of GBP2.1 billion and additional 
  investments of GBP0.1 billion, partly offset by GBP0.3 billion free 
  cash flow, GBP0.4 billion proceeds from investments, including GBP0.3 
  billion proceeds from the Innoviva disposal and GBP0.4 billion of 
  net favourable exchange impacts from the translation of non-Sterling 
  denominated debt and exchange on other financing items. 
  At 30 June 2021, GSK had short-term borrowings (including overdrafts 
  and lease liabilities) repayable within 12 months of GBP5.0 billion 
  with loans of GBP2.6 billion repayable in the subsequent year. 
 
 
 Returns to shareholders 
 
 
 Quarterly dividends 
  The Board has declared a second interim dividend for 2021 of 19 pence 
  per share (Q2 2020: 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 2021 at 
  the current level of 80p per share, subject to any material change 
  in the external environment or performance expectations. 
  At the New GSK Investor Update on 23 June GSK set out that from 2022 
  a progressive dividend policy will be implemented, guided by a 40 
  to 60 percent pay-out ratio through the investment cycle. This is 
  a key part of the capital allocation framework. For 2022, for the 
  first half of the year, GSK expects to declare a 27p dividend for 
  the current group. GSK is on track to separate into two companies 
  early in the second half of 2022. GSK expects the aggregate dividend, 
  across the two new businesses to be 28p per share for the second 
  half. In aggregate this would represent on a full year 2022 basis 
  the equivalent of a Group dividend of 55p per share, representing 
  a 31% decrease from the 80p/share dividend expected for 2021. This 
  expected, aggregate 55p per share dividend for full year 2022 is 
  comprised of 44p representing New GSK's policy, and an expected 11p 
  from the Consumer Healthcare business. Dividend policy for the new 
  Consumer Healthcare company will be set by its Board of Directors. 
  In 2023, the first full year of standalone operations for New GSK, 
  GSK expects to declare a full year dividend of 45p per share. 
  Payment of dividends 
  The equivalent interim dividend receivable by ADR holders will be 
  calculated based on the exchange rate on 5 October 2021. 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 19 August 2021, with a record date of 
  20 August 2021 and a payment date of 7 October 2021.

 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 2020. 
  At 30 June 2021, the Group's aggregate provision for legal and other 
  disputes (not including tax matters described on page 22) was GBP0.2 
  billion (31 December 2020: GBP0.3 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. 
 
  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. 
 
  Significant developments since the date of the Annual Report 2020 
  are as follows: 
 
  On 1 June 2021, the Court overseeing the Zofran Multidistrict Litigation 
  (MDL) in the District of Massachusetts granted GSK's motion for summary 
  judgment on federal preemption grounds. The District Court granted 
  judgment for GSK in all cases pending in the MDL and closed the MDL 
  proceeding. On 1 July 2021, Plaintiffs filed a notice to appeal the 
  preemption decision with respect to all cases in the MDL to the United 
  States Court of Appeals for the First Circuit. 
 
 
 Additional information 
 
 
 Accounting policies and basis of preparation 
 This unaudited Results Announcement contains condensed financial 
  information for the three and six months ended 30 June 2021, is prepared 
  in accordance with the Disclosure Guidance and Transparency Rules 
  (DTR) of the Financial Conduct Authority and United Kingdom adopted 
  IAS34 'Interim financial reporting' and should be read in conjunction 
  with the Annual Report 2020, which was prepared in accordance with 
  United Kingdom adopted International Financial Reporting Standards. 
  This Results Announcement has been prepared applying consistent accounting 
  policies to those applied by the Group in the Annual Report 2020. 
  The Group has not identified any changes to its key sources of accounting 
  judgements or estimations of uncertainty compared with those disclosed 
  in the Annual Report 2020. 
 
 
 This Results Announcement does not constitute statutory accounts 
  of the Group within the meaning of sections 434(3) and 435(3) of 
  the Companies Act 2006. The full Group accounts for 2020 were published 
  in the Annual Report 2020, which has been delivered to the Registrar 
  of Companies and on which the report of the independent auditor was 
  unqualified and did not contain a statement under section 498 of 
  the Companies Act 2006. 
 
  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. In the first half of 2021, as anticipated, the pandemic 
  impacted Group performance primarily in demand for Vaccines as a 
  result of governments' prioritisation of COVID-19 vaccination programmes 
  and of ongoing containment measures impacting customers' ability 
  and willingness to access vaccination services across all regions. 
  We remain confident in the underlying demand for our Vaccine products 
  and are encouraged by the rate at which COVID-19 vaccinations are 
  being deployed in many countries, particularly the US and UK, which 
  provides support for healthcare systems returning to normal, though 
  the pace varies in other key markets. We continue to monitor the 
  situation closely, as this continues to be a very dynamic and uncertain 
  situation, with the ultimate severity, duration and impact unknown 
  at this point including potential impacts on trading results, clinical 
  trials, supply continuity and our employees. The situation could 
  change at any time and there can be no assurance that the COVID-19 
  pandemic will not have a material adverse impact on the future results 
  of the Group. 
 
 
 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: 
 
 
                        Q2 2021   Q2 2020   H1 2021   H1 2020   2020 
                       --------  --------  --------  --------  ----- 
 
 Average rates: 
   US$/GBP                 1.40      1.25      1.39      1.27   1.29 
   Euro/GBP                1.16      1.13      1.15      1.15   1.13 
   Yen/GBP                  152       134       149       137    137 
 
 Period-end rates: 
   US$/GBP                 1.39      1.23      1.39      1.23   1.36

 During Q2 2021 average Sterling exchange rates were stronger against 
  the US Dollar, the Yen and the Euro compared with the same period 
  in 2020. During the six months ended 30 June 2021, average Sterling 
  exchange rates were stronger against the US Dollar and the Yen but 
  flat against the Euro compared with the same period in 2020. Period-end 
  Sterling exchange rates were stronger against the US Dollar, the 
  Euro and the Yen compared with the 2020 period-end rates. 
 
 
 Net assets 
 The book value of net assets increased by GBP770 million from GBP20,808 
  million at 31 December 2020 to GBP21,578 million at 30 June 2021. 
  This primarily reflected the Total profit for the period, the re-measurement 
  gains on the defined benefit plans and the increase in the fair value 
  of equity investments exceeding the adverse exchange movements and 
  the dividends paid during the period. 
  The carrying value of investments in associates and joint ventures 
  at 30 June 2021 was GBP76 million (31 December 2020: GBP364 million), 
  with a market value of GBP76 million (31 December 2020: GBP364 million). 
  During Q2 2021, the Group sold all of its shares in Innoviva Inc 
  back to Innoviva for GBP277 million. 
  At 30 June 2021, the net deficit on the Group's pension plans was 
  GBP1,882 million compared with GBP2,104 million at 31 December 2020. 
  The decrease in the net deficit primarily arose from an increase 
  in the rates used to discount UK pension liabilities from 1.4% to 
  1.9%, and US pension liabilities from 2.3% to 2.7%, partly offset 
  by an increase in the UK inflation rate from 2.8% to 3.1% and lower 
  UK assets. 
  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 GBP870 million (31 December 
  2020: GBP960 million). 
  Contingent consideration amounted to GBP5,760 million at 30 June 
  2021 (31 December 2020: GBP5,869 million), of which GBP5,199 million 
  (31 December 2020: GBP5,359 million) represented the estimated present 
  value of amounts payable to Shionogi relating to ViiV Healthcare 
  and GBP504 million (31 December 2020: GBP477 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 2021, GBP717 million (31 December 2020: GBP745 
  million) is expected to be paid within one year.

 Contingent liabilities and commitments 
 There were contingent liabilities at 30 June 2021 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. 
  During the quarter on 14 June 2021 GSK signed an agreement with iTeos 
  Therapeutics. On 2 July 2021 GSK signed an agreement with Alector. 
  These agreements result in total contractual commitments of approximately 
  GBP956 million for upfront payments as at 30 June 2021 closing Dollar 
  spot rate. The agreement with Alector is conditional on review by 
  the appropriate regulatory agencies under the Hart-Scott-Rodino Act. 
 
 
 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 GBP267 million (H1 2020: net losses of GBP800 million) 
  reported in other operating income and net gains of GBP90 million 
  (H1 2020: net gains of GBP151 million) reported in other comprehensive 
  income were attributable to Level 3 financial instruments held at 
  the end of the period. Net gains of GBP90 million (H1 2020: GBP151 
  million) attributable to Level 3 financial instruments reported in 
  Other comprehensive income as Fair value movements on equity investments 
  were all attributable to financial instruments held at the end of 
  the period, of which net gains of GBP99 million (H1 2020: nil) arose 
  prior to transfer from Level 3 on equity investments which transferred 
  to a Level 1 valuation methodology as a result of listing on a recognised 
  stock exchange during the period. Net gains and losses include the 
  impact of exchange movements. 
 
  Financial liabilities measured using Level 3 valuation methods at 
  30 June included GBP5,199 million (H1 2020: GBP5,436 million) of 
  contingent consideration for the acquisition in 2012 of the former 
  Shionogi-ViiV Healthcare joint venture and GBP504 million (H1 2020: 
  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 and the Sterling/US 
  Dollar exchange. 
 
 
 The table below shows, on an indicative basis, the income statement 
  and balance sheet sensitivity to reasonably possible changes in key 
  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. Transfers from Level 
  3 relate to equity investments in companies which were listed on 
  stock exchanges during the 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: 
 
 --   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 
 
 --   Trade receivables carried at fair value - based on invoiced amount 
 
 --   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 
 
 --   Cash and cash equivalents carried at fair value - based on net 
       asset value of the funds 
 
 --   Contingent consideration for business acquisitions and divestments 
       - based on present values of expected future cash flows 
 
 
 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: 
 
 --   Company owned life insurance policies - based on cash surrender 
       value 
 
 --   Receivables and payables, including put options, carried at amortised 
       cost - approximates to the carrying amount 
 
 --   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 
 
 
 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 GBP870 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 2021. 
  The table below shows on an indicative basis the income statement 
  and balance sheet sensitivity to reasonably possible changes in the 
  key inputs to the measurement of this liability.

                         information in accordance with data privacy laws can 
                         lead to harm to individuals (e.g. financial, stress, 
                         prejudice) and GSK (e.g. fines, operational, financial 
                         and reputational). 
 
 Research practices     Failure to adequately conduct ethical and sound pre-clinical 
                         and clinical research. In addition, failure to engage 
                         in scientific activities that are consistent with 
                         the letter and spirit of the law, industry, or the 
                         Group's requirements. It comprises the following sub-risks: 
                         non-clinical and laboratory research; human subject 
                         research; data integrity; care, welfare and treatment

                         disclosure; regulatory filings and engagement; and 
                         patents.

                         and processing of hazardous chemicals and biological 
                         agents; control of releases of substances harmful 
                         to the environment in both the short and long term, 
                         leading to incidents which could disrupt our R&D and 
                         supply activities, harm employees, harm the communities 
                         and harm the local environments in which we operate.

  sustainability         risks, current and future regulatory requirements 
                         for environmental policies and taxes, delivery and 
                         performance of management environmental objectives, 
                         leading to reduced supply chain resilience, product 
                         life cycle management issues, loss of trust/reputation 
                         with employees, investors, customers, regulators and 
                         other stakeholders, increased costs, loss of sales 
                         or market access and negative impacts on the environment. 
 
 Information security   The risk that unauthorised disclosure, theft, unavailability 
                         or corruption of GSK's information or key information 
                         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. 
 
 Transformation         Failure to deliver the plan for successful transformation 
                         and separation of GSK into two competitive standalone 
                         companies; New GSK, a biopharma company and new Consumer 
                         Healthcare. 
 
 
 
 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/outflow 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 65. 
 
  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 H1 2020 included 
  six months of results of the former Pfizer consumer healthcare business 
  from 1 January 2020. 
 
  The Group has presented in this Results Announcement pro-forma growth 
  rates at CER in H1 2020 for sales excluding brands divested/under 
  review for Consumer Healthcare and sales for certain categories of 
  consumer healthcare products taking account of this transaction. 
  Pro-forma growth rates for the half year are calculated comparing 
  reported results for H1 2020, calculated applying the exchange rates 
  used in the comparative period, with the results for H1 2019 adjusted 
  to include the equivalent six months of results of the former Pfizer 
  consumer healthcare business during H1 2019, as consolidated (in 
  US$) and included in Pfizer's US GAAP results. 
 
  2 year Compound Annual Growth Rate 
  CAGR is defined as the compound annual growth rate and shows the 
  annualised average rate of pro-forma revenue growth between two given 
  years, assuming growth takes place at an exponentially compounded 
  rate. For Consumer Healthcare, the 2 year revenue CAGR has been shared 
  showing the annualised average rate of pro-forma revenue growth between 
  2019 and 2021. 
 
  COVID-19 solutions 
  COVID-19 solutions include the sales of pandemic adjuvant and other 
  COVID-19 solutions including vaccine manufacturing and sotrovimab 
  and the associated costs but does not include reinvestment in R&D. 
  This categorisation is used by management and we believe is helpful 
  to investors through providing clarity on the results of the Group 
  by showing the contribution to growth from COVID-19 solutions .

 Outlook, assumptions and cautionary statements 
 
 
 2021 guidance 
  Our guidance range for 2021 is a decline of mid to high-single digit 
  percent adjusted EPS at CER and excludes any contribution from COVID-19 
  related solutions. 
  2021-2026 sales and adjusted operating profit growth outlooks, 2026 
  cash generated from operations outlook, 2031 sales ambition and 2021-2023 
  dividend expectations 
  In June 2021, GSK announced that it expected New GSK to deliver sales 
  growth and adjusted operating profit growth of more than 5% and more 
  than 10%, respectively, CAGR at constant exchange rates over the 
  five year period 2021-2026 (with 2021 as the base year). These financial 
  outlooks exclude any contribution from COVID-19 related revenues. 
  New GSK expects to improve adjusted operating margin from the mid-20s% 
  in 2021 to over 30% by 2026 and cash generated from operations is 
  expected to exceed GBP10 billion by 2026. By 2031, New GSK aims to 
  deliver sales of more than GBP33 billion (at constant exchange rates). 
  Assumptions related to 2021 guidance, 2021-2026 outlooks, 2031 sales 
  ambition and 2021-2023 dividend expectations 
  In outlining the guidance for 2021 and future five-year 2021-26 outlook, 
  2031 ambition and dividend expectations, the Group has made certain 
  assumptions about the healthcare sector (including regarding possible 
  governmental, legislative and regulatory reform), the different markets 
  and competitive landscape in which it operates and the delivery of 
  revenues and financial benefits from its current portfolio, its development 
  pipeline of drugs and vaccines, its restructuring programmes and 
  its plans for the separation of Consumer Healthcare. 
  2021 guidance 
  The Group has made planning assumptions for 2021 that healthcare 
  systems and consumer trends will approach normality in the second 
  half of the year, and we expect turnover to be flat to low single 
  digit growth for the Pharmaceuticals and Vaccines businesses and 
  low to mid-single digit growth for Consumer Healthcare excluding 
  brands divested/under review. These planning assumptions as well 
  as earnings guidance and dividend expectations assume no material 
  interruptions to supply of the Group's products, no material mergers, 
  acquisitions or disposals, 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 assume no material changes in the healthcare 
  environment. The 2021 guidance factors in all divestments and product 
  exits announced to date, including product divestments planned in 
  connection with the formation of the Consumer Healthcare Joint Venture 
  with Pfizer, and the non-core divestments planned to fund the cash 
  costs of the Separation Preparation restructuring programme. 
  The Group's guidance assumes successful delivery of the Group's integration 
  and restructuring plans. It also assumes that the integration and 
  investment programmes following the creation of the Consumer Healthcare 
  Joint Venture with Pfizer 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 guidance is given on a 
  constant currency basis. 
  New GSK's revenue, operating profit, operating margin and cash flow 
  outlooks, revenue ambition and dividend expectations 
  GSK expects and assumes the next several years to be challenging 
  for the healthcare industry with continued uncertainty related to 
  the impact of the COVID-19 pandemic on adult vaccinations and continued 
  pressure on pricing of pharmaceuticals. GSK also expects volume demand 
  for its products to increase, particularly for Shingrix in the US, 
  as healthcare systems are expected to return to normal following 
  disruption from governments' prioritisation of COVID-19 vaccination 
  programmes and ongoing measures to contain the pandemic, and for 
  Shingrix in China. 
  The assumptions for New GSK's revenue, operating profit, operating 
  margin and cash flow outlooks, revenue ambition and dividend expectations 
  assume successful delivery of the ongoing and planned integration 
  and restructuring plans and the planned demerger of Consumer Healthcare; 
  the delivery of revenues and financial benefits from its current 
  and development pipeline portfolio of drugs and vaccines (which have 
  been assessed for this purpose on a risk-adjusted basis, as described 
  further below); regulatory approvals of the pipeline portfolio of 
  drugs and vaccines that underlie these expectations (which have also 
  been assessed for this purpose on a risk-adjusted basis, as described 
  further below); no material interruptions to supply of the Group's 
  products; no material mergers, acquisitions or disposals or other 
  material business development transactions; 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 shareholdings in ViiV Healthcare. 
  GSK assumes no premature loss of exclusivity for key products over 
  the period. 
  The assumptions for New GSK's revenue, operating profit, operating 
  margin and cash flow outlooks, revenue ambition and dividend expectations 
  also factor in all divestments and product exits announced to date 
  as well as material costs for investment in new product launches 
  and R&D. Pipeline risk-adjusted sales are based on the latest internal 
  estimate of the probability of technical and regulatory success for 
  each asset in development. 
  Notwithstanding these outlooks and expectations, there is still uncertainty 
  as to whether our assumptions, targets, outlooks expectations and 
  ambitions will be achieved, including based on the other assumptions 
  outlined above. 
  All outlook and ambition statements are given on a constant currency 
  basis and use 2021 forecast exchange rates as a base, assuming a 
  continuation of Q1 2021 closing rates (GBP1/$1.38, GBP1/EUR1.17, 
  GBP1/Yen 152). 2021-2026 outlook refers to the 5 years to 2026 with 
  2021 as the base year. 
  Assumptions and cautionary statement regarding forward-looking statements 
  The Group's management believes that the assumptions outlined above 
  are reasonable, and that the guidance, outlooks, ambitions and expectations 
  described in this report are achievable based on those assumptions. 
  However, given the forward-looking nature of these guidance, outlooks, 
  ambitions and expectations, 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 legislation, regulation, 
  government actions or intellectual property protection, product development 
  and approvals, 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', 'aim', 'ambition' 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 2020 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.

 Independent review report to GlaxoSmithKline plc 
 
 
 We have been engaged by GlaxoSmithKline plc ("the Company") to review 
  the condensed financial information in the Results Announcement of 
  the Company for the three and six months ended 30 June 2021. 
 
 
 What we have reviewed 
 The condensed financial information comprises: 
 --    the income statements and statements of comprehensive income for 
        the three and six month periods ended 30 June 2021 on pages 46 
        to 48; 
 --    the balance sheet as at 30 June 2021 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 condensed 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 64, 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 condensed 
  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 United Kingdom adopted International 
  Financial Reporting Standards. The condensed financial statements 
  included in this Results Announcement have been prepared in accordance 
  with United Kingdom adopted International Accounting Standard 34, 
  "Interim Financial Reporting". 
 
  Our responsibility 
  Our responsibility is to express to the Company a conclusion on the 
  condensed 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 condensed financial statements in the Results 
  Announcement for the three and six months ended 30 June 2021 are 
  not prepared, in all material respects, in accordance with United 
  Kingdom adopted International Accounting Standard 34 and the Disclosure 
  Guidance and Transparency Rules of the United Kingdom's Financial 
  Conduct Authority.
