 Emma Walmsley, Chief Executive Officer, GSK said: 
  "GSK has made further good progress this quarter with CER sales growth 
  in all three businesses, improvements in the Group operating margin 
  at CER and Adjusted earnings per share growth of 14% (CER). Strong 
  commercial execution for key products and new launches, notably Shingrix, 
  together with an effective focus on cost control is driving this 
  improved performance and we now expect 2018 Adjusted EPS growth of 
  8-10% at CER. Looking further ahead, we remain confident in our ability 
  to deliver the Group outlooks for sales and EPS growth we previously 
  set for the period 2016-2020." 
 
 
 The Total results are presented under 'Income Statements' on page 
  40 and Adjusted results reconciliations are presented on pages 16, 
  24 and 58 to 61. Adjusted results are a non-IFRS measure that allows 
  key trends and factors in the Group's performance to be more easily 
  identified by shareholders. Non-IFRS measures may be considered in 
  addition to, but not as a substitute for, or superior to, information 
  presented in accordance with IFRS. The definitions of GBP% or AER% 
  growth, CER% growth, Adjusted results, free cash flow and other non-IFRS 
  measures are set out on page 37. All expectations and targets regarding 
  future performance should be read together with "Assumptions related 
  to 2018 guidance and 2016-2020 outlook" and "Assumptions and cautionary 
  statement regarding forward-looking statements" on page 38. 
 
 
 2018 guidance update 
 
 With continued strong trading in the first nine months of 2018, the 
  Group is tightening its full year guidance range towards the upper 
  end of previous expectations. The Group now expects full year 2018 
  Adjusted EPS growth of 8 to 10% at CER, whether or not a generic 
  competitor to Advair is launched in the US in 2018. 
  This revised guidance primarily reflects an increase in our expectations 
  for sales of Shingrix, which we now expect to be GBP700-750 million 
  in 2018. 
  We continue to expect the effective tax rate for 2018 to be approximately 
  19-20% of Adjusted profits after the impact of US tax reform. 
  If exchange rates were to hold at the closing rates on 30 September 
  2018 ($1.30/GBP1, EUR1.12/GBP1 and Yen 148/GBP1) for the rest of 
  2018, the estimated negative impact on full-year 2018 Sterling turnover 
  growth would be around 3% and if exchange gains or losses were recognised 
  at the same level as in 2017, the estimated negative impact on 2018 
  Sterling Adjusted EPS growth would be around 6%. 
 
 
 Total and Adjusted results 
 
 Total results represent the Group's overall performance. However, 
  these results can contain material unusual or non-operational items 
  that may obscure the key trends and factors determining the Group's 
  operational performance. As a result, GSK also reports Adjusted results, 
  which is a non-IFRS measure. GSK believes that Adjusted results allow 
  the Group's performance to be more easily and clearly identified 
  by shareholders. The definition of Adjusted results, as set out on 
  page 37, also aligns the Group's results with the majority of its 
  peer companies and how they report earnings. 
  Adjusted results may exclude significant costs such as those from 
  major restructuring programmes, significant legal charges or transaction 
  items. Major restructuring charges have been reported as an adjusting 
  item since the Group adopted its current reporting structure in 2012. 
  Estimated charges from the major restructuring programmes approved 
  by the Board, are set out on page 25. Adjusted results include the 
  benefits arising from the major restructuring programmes. 
  As Adjusted results may exclude significant costs, such as those 
  from major restructuring programmes or significant legal charges, 
  they should not be regarded as a complete picture of the Group's 
  financial performance which is presented in its Total results. When 
  restructuring charges are excluded, Adjusted earnings will be higher 
  than Total earnings. The exclusion of other Adjusting items may result 
  in Adjusted earnings being materially higher or lower than Total 
  earnings. 
  Reconciliations between Total and Adjusted results, as set out on 
  pages 16, 24 and 58 to 61, including detailed breakdowns of the key 
  adjusting items, are provided to shareholders to ensure full visibility 
  and transparency as they assess the Group's performance. 
  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. 
  In addition, it should be noted that contingent consideration cash 
  payments are made each quarter primarily to Shionogi by ViiV Healthcare 
  which reduce the balance sheet liability and are hence not recorded 
  in the income statement. The cash payments made to Shionogi by ViiV 
  Healthcare for the nine months to 30 September 2018 were GBP584 million. 
  An explanation of the acquisition-related arrangements with ViiV 
  Healthcare, including details of cash payments to Shionogi, is set 
  out on page 56.

 Group turnover was up 3% AER, 6% CER to GBP8,092 million, with CER 
  growth delivered by all three businesses. 
  Pharmaceuticals sales grew 1% AER, 3% CER, driven primarily by the 
  growth in sales of HIV and the new Respiratory products, Nucala 
  and the Ellipta portfolio. This was partly offset by lower sales 
  of Seretide/Advair and Established Pharmaceuticals. Overall Respiratory 
  sales were up 3% AER, 5% CER. 
  Vaccines sales were up 14% AER, 17% CER, driven primarily by sales 
  of Shingrix in the US and market growth of Bexsero, partly offset 
  by declines in some Established Vaccines. 
  Consumer Healthcare sales declined 1% AER but grew 3% CER reflecting 
  growth in Wellness, Oral health and Nutrition, partly offset by 
  a decline in Skin health, the divestments of some smaller brands 
  including Horlicks and MaxiNutrition in the UK as well as the final 
  quarter's impact of the implementation of the Goods & Services Tax 
  (GST) in India.

 US sales grew 11% AER, 13% CER driven by strong performances from 
  Shingrix, HIV products and new Respiratory sales. 
  Europe sales declined 2% AER, 2% CER as growth from HIV and the 
  new Respiratory products was more than offset by continued generic 
  competition to Epzicom as well as a decrease in Bexsero sales largely 
  due to the completion of the vaccination of catch-up cohorts in 
  certain markets which benefited Q3 2017. Growth in new Respiratory 
  products more than offset the decline in Seretide. 
  In International, sales declined 2% AER but grew 4% CER reflecting 
  strong growth in the new Respiratory products as well as HIV sales. 
  Sales in Emerging Markets were flat AER, but grew 8% CER, driven 
  by strong growth of Cervarix in China and Horlicks in India.

 Group turnover was flat at AER but increased 4% CER to GBP22,624 
  million, with CER growth delivered by all three businesses. 
  Pharmaceuticals sales were down 2% AER but up 2% CER, driven primarily 
  by the growth in HIV sales and the new Respiratory products, Nucala 
  and the Ellipta portfolio. This was partly offset by lower sales 
  of Seretide/Advair and Established Pharmaceuticals. Overall Respiratory 
  sales declined 3% AER but grew 1% CER. 
  Vaccines sales were up 12% AER, 15% CER, primarily driven by sales 
  of Shingrix in the US, a competitor supply shortage in Hepatitis 
  and market growth for Bexsero, partly offset by declines in some 
  Established Vaccines. 
  Consumer Healthcare sales declined 2% AER but grew 2% CER with continued 
  strong broad-based growth in Oral health partly offset by a decline 
  in Panadol, the divestments of some smaller brands including Horlicks 
  and MaxiNutrition in the UK as well as the impact of the implementation 
  of the Goods & Services Tax (GST) in India.

  Europe sales were flat at AER but down 1% CER, as declines in Established 
  Pharmaceuticals and Meningitis vaccines more than offset growth 
  from Tivicay and Triumeq. Growth in the new Respiratory products 
  more than offset the decline in Seretide. 
  In International, sales declined 3% AER but grew 4% CER, reflecting 
  strong growth in Tivicay, Triumeq, the Respiratory portfolio and 
  Cervarix in China, following its recent launch. Sales in Emerging 
  Markets declined 3% AER, but grew 4% CER.

 Pharmaceuticals turnover in the quarter was GBP4,221 million, up 
  1% AER, 3% CER, driven primarily by growth in HIV and Respiratory. 
  HIV sales were up 11% AER, 12% CER, to GBP1,209 million, reflecting 
  further strong performances by Triumeq and Tivicay and continued 
  growth from Juluca. Respiratory sales were up 3% AER, 5% CER, to 
  GBP1,666 million, with growth from the Ellipta portfolio and Nucala 
  more than offsetting lower sales of Seretide/Advair. Sales of Established 
  Pharmaceuticals fell 12% AER, 9% CER, to GBP1,224 million. 
  In the US, sales grew 3% AER, 4% CER, with growth in HIV, Respiratory 
  and Benlysta more than offsetting declines in Established Pharmaceuticals. 
  In Europe, sales grew 1% AER but were flat at CER, with growth in 
  the Respiratory portfolio offsetting the continued impact of generic 
  competition to Epzicom and Avodart. International sales declined 
  3% AER but grew 2% CER, with growth driven by HIV and the new Respiratory 
  portfolio. 
 
  Respiratory 
  Total Respiratory sales were up 3% AER, 5% CER, with growth in all 
  regions. The US was up 4% AER, 5% CER, while in Europe sales grew 
  5% AER, 4% CER. International grew 1% AER, 6% CER, including Japan 
  up 5% AER, 2% CER. Growth from the Ellipta portfolio and Nucala more 
  than offset lower sales of Seretide/Advair, which declined 17% AER, 
  15% CER globally. 
  Sales of Nucala were GBP145 million in the quarter and grew 59% AER, 
  62% CER, continuing to benefit from the global rollout of the product. 
  US sales of Nucala grew 43% AER, 44% CER to GBP87 million. 
  Sales of Ellipta products were up 34% AER, 35% CER to GBP500 million 
  driven by continued growth in all regions. In the US, sales grew 
  34% AER, 36% CER, reflecting further market share gains, partly offset 
  by the impact of continued competitive and pricing pressures, particularly 
  for ICS/LABAs. In Europe, sales grew 37% AER, 36% CER. Sales of Trelegy 
  Ellipta, our new once daily closed triple product, contributed GBP42 
  million in the quarter, benefiting from an expanded label in the 
  US. 
  Relvar/Breo Ellipta sales grew 15% AER, 16% CER, to GBP258 million, 
  with Europe up 20% AER, 20% CER to GBP59 million, and International 
  up 22% AER, 24% CER to GBP60 million. In the US sales grew 9% AER, 
  11% CER to GBP139 million, with volume growth of 27% reflecting continued 
  market share growth and the benefit from lower prior period payer 
  rebate adjustments, partly offset by increased competitive pricing 
  pressures. Anoro Ellipta sales grew 34% AER, 34% CER to GBP115 million, 
  driven by gains in the US. All Ellipta products, Breo, Anoro, Incruse, 
  Arnuity and Trelegy, continued to grow market share in the US during 
  the quarter. 
  Sales of New Respiratory products, comprising Ellipta products and 
  Nucala, grew 39% AER, 40% CER to GBP645 million. 
  Seretide/Advair sales declined 17% AER, 15% CER to GBP619 million. 
  Sales of Advair in the US declined 20% AER, 19% CER (3% volume decline 
  and 16% negative impact of price) primarily reflecting increased 
  competitive pricing pressures. In Europe, Seretide sales were down 
  20% AER, 20% CER to GBP132 million (16% volume decline and a 4% price 
  decline). This reflected continued competition from generic products 
  and the transition of the Respiratory portfolio to newer products. 
  In International, sales of Seretide were down 7% AER, 2% CER, to 
  GBP178 million (3% volume decline and 1% positive impact of price), 
  with a decline in markets with generic competition partly offset 
  by growth from certain other developing markets. 
  HIV 
  HIV sales increased 11% AER, 12% CER to GBP1,209 million in the quarter, 
  with the US up 11% AER, 12% CER, Europe up 2% AER, 1% CER and International 
  up 27% AER, 34% CER. The growth was driven by Triumeq and Tivicay 
  which recorded sales of GBP669 million and GBP432 million, respectively, 
  in the quarter. Juluca sales were GBP37 million in the quarter, mainly 
  in the US. 
  This growth was partly offset by the impact of generic competition 
  to Epzicom/Kivexa, particularly in Europe. Sales declined 51% AER, 
  47% CER to GBP24 million. 
  Immuno-inflammation 
  Sales in the quarter were up 28% AER, 29% CER, primarily driven by 
  Benlysta which grew 29% AER, 31% CER to GBP121 million. In the US, 
  Benlysta grew 27% AER, 29% CER to GBP108 million. 
  Established Pharmaceuticals 
  Sales of Established Pharmaceuticals in the quarter were GBP1,224 
  million, down 12% AER, 9% CER. The Avodart franchise was flat at 
  AER but up 1% CER to GBP144 million, with growth in International 
  largely offset by the loss of exclusivity in Europe, with the US 
  generic impact now broadly annualised. Coreg franchise sales declined 
  76% AER, 78% CER to GBP9 million following a generic Coreg CR entrant 
  to the US market in Q4 2017. Augmentin sales declined 10% AER, 5% 
  CER to GBP133 million.

 Vaccines turnover grew 14% AER, 17% CER to GBP1,924 million, primarily 
  driven by market expansion and share growth for Shingrix, and market 
  growth for Bexsero. Established Vaccines declined 4% AER, 3% CER 
  reflecting lower sales of DTPa-containing vaccines (Infanrix, Pediarix 
  and Boostrix) due to increased competitive pressures, particularly 
  in Europe, and unfavourable CDC stockpile movements in the US. 
 
  Meningitis 
  Meningitis sales grew 10% AER, 15% CER to GBP329 million. Bexsero 
  sales increased 18% AER, 24% CER largely due to demand and share 
  gains in the US and continued growth in private market sales in International, 
  partly offset by the completion of vaccination of catch-up cohorts 
  in certain markets in Europe which benefited 2017. Menveo sales were 
  up 4% AER, 8% CER, also driven by demand and share gains in the US, 
  partly offset by supply constraints in Europe and International. 
  Influenza 
  Fluarix/FluLaval sales declined 11% AER, 7% CER to GBP304 million, 
  driven by increased price competition in the US, partly offset by 
  stronger sales in Europe. 
  Shingles 
  Shingrix recorded sales of GBP286 million in the quarter in the US 
  and Canada, driven by demand and share gains. US sales of Shingrix 
  benefited from market growth in new patient populations now covered 
  by immunisation recommendations and achieved a 99% market share in 
  the quarter. An allocation process has been implemented in the US 
  to help manage inventory and supply to ensure patients have the opportunity 
  to complete the two-dose series. 
 
  Established Vaccines 
  Sales of the DTPa-containing vaccines (Infanrix, Pediarix and Boostrix) 
  were down 12% AER, 11% CER. This was primarily driven by Infanrix, 
  Pediarix sales, down 18% AER, 17% CER to GBP160 million, reflecting 
  unfavourable CDC stockpile movements in the US and increased competitive 
  pressures, particularly in Europe, partly offset by stronger demand 
  in International. 
 
  Hepatitis vaccines grew 1% AER, 3% CER to GBP213 million, benefiting 
  from a competitor supply shortage and stronger demand in the US and 
  Europe, partly offset by unfavourable CDC stockpile movements in 
  the US. 
 
  Rotarix sales declined 3% AER, 2% CER to GBP152 million, mainly driven 
  by an unfavourable comparison with the reversal of a returns provision 
  in International in Q3 2017, partly offset by the favourable phasing 
  of tenders. 
 
  Synflorix sales grew 4% AER, 4% CER to GBP119 million, mainly due 
  to higher demand in International and favourable year-on-year phasing, 
  partly offset by lower pricing in Emerging Markets. 
 
  Cervarix sales increased 49% AER, 51% CER to GBP55 million, primarily 
  driven by market expansion in China.

 Consumer Healthcare sales declined 1% AER but grew 3% CER in the 
  quarter to GBP1,947 million as growth in Wellness, Oral health and 
  Nutrition was partly offset by a decline in Skin health. Strong performances 
  in the US, Central & Eastern Europe and International markets were 
  partly offset by a decline in Western Europe due to challenging trading 
  conditions and increased competition. 
  The divestments of a number of tail brands, including Horlicks and 
  MaxiNutrition in the UK, generic competition to Transderm Scop in 
  the US and the final quarter's impact of the implementation of the 
  Goods & Service Tax (GST) in India in aggregate adversely impacted 
  growth by approximately one percentage point in the quarter. 
  Wellness 
  Wellness sales were flat at AER but grew 3% CER to GBP1,017 million, 
  mainly due to Flonase benefiting from promotional phasing in the 
  US, high-single digit growth in Voltaren due to new launches and 
  favourable shipment phasing as well as seasonal sell-in of Otrivin. 
  Panadol sales declined, reflecting the impact of the continuing change 
  in the route-to-market model in South-East Asia and the discontinuation 
  of slow-release Panadol products in the Nordic countries. 
  Oral health 
  Oral health sales declined 1% AER but grew 2% CER to GBP624 million, 
  primarily reflecting growth of Sensodyne and Denture care. Oral health 
  was impacted by slower growth in International markets but the US 
  portfolio grew strongly, supported by Sensodyne Rapid which launched 
  earlier this year. Denture care delivered mid-single digit growth 
  through broad-based market performance. 
 
  Nutrition 
  Nutrition sales declined 2% AER but grew 5% CER to GBP167 million. 
  The Nutrition business in India performed strongly across the product 
  portfolio, benefiting from new innovations including Horlicks Protein+ 
  which was launched earlier in the year. Divestments and GST impacted 
  Nutrition growth by eight percentage points. 
 
  Skin health 
  Skin health declined 7% AER, 4% CER to GBP139 million with strong 
  growth in China more than offset by a weaker performance in Europe 
  following a strong second quarter.

 Pharmaceuticals turnover in the nine months was GBP12,459 million, 
  down 2% AER but up 2% CER, driven primarily by the growth in HIV 
  sales, which were up 8% AER, 12% CER to GBP3,446 million, reflecting 
  further strong performances by Triumeq and Tivicay and continued 
  growth from Juluca. Respiratory sales declined 3% AER but grew 1% 
  CER, to GBP4,937 million, with growth from the Ellipta portfolio 
  and Nucala partly offset by lower sales of Seretide/Advair. Sales 
  of Established Pharmaceuticals fell 10% AER, 6% CER. 
  In the US, sales declined 4% AER but grew 2% CER, with growth in 
  the HIV portfolio and Benlysta offsetting declines in Established 
  Pharmaceuticals and Respiratory. In Europe, sales grew 1% AER but 
  declined 1% CER, with growth in the Respiratory portfolio only partly 
  offsetting the continued impact of generic competition to Epzicom 
  and Avodart. International sales declined 2% AER but grew 4% CER, 
  driven by HIV and the new Respiratory portfolio. 
  Respiratory 
  Total Respiratory sales declined 3% AER but grew 1% CER, with the 
  US down 8% AER, 3% CER. In Europe, sales grew 4% AER, 3% CER and 
  International sales were flat at AER but up 6% CER, driven primarily 
  by higher sales in Japan. Growth from the Ellipta portfolio and Nucala 
  was offset by lower sales of Seretide/Advair. 
  Sales of Nucala were GBP390 million in the nine months, up 75% AER, 
  81% CER, continuing to benefit from the global rollout of the product. 
  US sales of Nucala grew 53% AER, 61% CER to GBP234 million. 
  Sales of Ellipta products were up 26% AER, 31% CER, driven by continued 
  growth in all regions. In the US, sales grew 20% AER, 27% CER, reflecting 
  further market share gains, partly offset by the impact of continued 
  competitive and pricing pressures, particularly for ICS/LABAs. In 
  Europe, sales grew 38% AER, 37% CER, and International sales grew 
  34% AER, 42% CER. Sales of Trelegy Ellipta, our new once daily closed 
  triple product, contributed GBP79 million to total Ellipta sales, 
  benefiting from an expanded label in the US. 
  Relvar/Breo Ellipta sales grew 6% AER, 11% CER, to GBP756 million, 
  primarily driven by growth in Europe, which was up 23% AER, 22% CER 
  to GBP182 million, and in International, which was up 27% AER, 33% 
  CER to GBP179 million. In the US, Breo Ellipta sales declined 6% 
  AER, 1% CER, with volume growth of 32%, reflecting continued market 
  share growth, more than offset by the combined impact of prior period 
  payer rebate adjustments and increased competitive pricing pressures. 
  Anoro Ellipta sales grew 42% AER, 48% CER to GBP332 million, driven 
  by gains in the US. All Ellipta products, Breo, Anoro, Incruse, Arnuity 
  and Trelegy, continued to grow market share in the US during the 
  nine months. 
  Sales of New Respiratory products, comprising Ellipta products and 
  Nucala, grew 34% AER, 40% CER to GBP1,785 million. 
  Seretide/Advair sales declined 24% AER, 21% CER to GBP1,775 million. 
  Sales of Advair in the US declined 34% AER, 30% CER (6% volume decline 
  and 24% negative impact of price) primarily reflecting increased 
  competitive pricing pressures. In Europe, Seretide sales were down 
  19% AER, 20% CER to GBP449 million (12% volume decline and an 8% 
  price decline). This reflected continued competition from generic 
  products and the transition of the Respiratory portfolio to newer 
  products. In International, sales of Seretide were down 10% AER, 
  5% CER, to GBP528 million (5% volume decline and no price impact), 
  with a decline in markets with generic competition partly offset 
  by growth from certain other developing markets. 
  HIV 
  HIV sales increased 8% AER, 12% CER to GBP3,446 million in the nine 
  months, with the US up 7% AER, 13% CER, Europe up 7% AER, 6% CER 
  and International up 14% AER, 21% CER. The growth was driven by increased 
  market share for Triumeq and Tivicay with sales of GBP1,957 million 
  and GBP1,187 million, respectively, in the nine months. Juluca was 
  approved in the US in November 2017 and recorded sales of GBP71 million 
  in the nine months. 
  This growth was partly offset by the impact of generic competition 
  to Epzicom/Kivexa, particularly in Europe. Sales declined 54% AER, 
  52% CER to GBP87 million. 
  Immuno-inflammation 
  Sales in the nine months were up 20% AER, 26% CER, primarily driven 
  by Benlysta, which grew 21% AER, 27% CER to GBP335 million. In the 
  US, Benlysta grew 19% AER, 25% CER to GBP299 million. 
 
  Established Pharmaceuticals 
  Sales of Established Pharmaceuticals were GBP3,740 million, down 
  10% AER, 6% CER, with the decline partly mitigated by favourable 
  prior period payer rebate adjustments and some post-divestment inventory 
  sales. 
  The Avodart franchise was down 9% AER, 6% CER to GBP423 million, 
  primarily due to the loss of exclusivity in Europe, with the US generic 
  impact now broadly annualised. Coreg franchise sales declined 68% 
  AER, 67% CER to GBP36 million following a generic Coreg CR entrant 
  to the US market in Q4 2017. Augmentin sales declined 5% AER but 
  grew 1% CER to GBP424 million with improved demand in Emerging Markets.

 Vaccines turnover grew 12% AER, 15% CER to GBP4,415 million, primarily 
  driven by growth in sales of Shingrix, Hepatitis vaccines, which 
  benefited from a competitor supply shortage, the launch of Cervarix 
  in China and market growth for Bexsero. This was partly offset by 
  lower Synflorix sales, reflecting lower pricing and demand in Emerging 
  Markets, and lower sales of DTPa-containing vaccines (Infanrix, Pediarix 
  and Boostrix) due to increased competitive pressures, particularly 
  in Europe, and unfavourable year-on-year CDC stockpile movements 
  in the US. 
  Meningitis 
  Meningitis sales grew 1% AER, 5% CER to GBP693 million. Bexsero sales 
  were up 7% AER, 12% CER driven by demand and share gains in the US, 
  together with continued growth in private market sales in International, 
  partly offset by the completion of vaccination of catch-up cohorts 
  in certain markets in Europe. Menveo sales fell 10% AER, 5% CER, 
  primarily reflecting a strong comparator performance and supply constraints 
  in Europe and International, partly offset by demand and share gains 
  in the US. 
  Influenza 
  Fluarix/FluLaval sales declined 12% AER, 8% CER to GBP330 million, 
  driven by increased price competition in the US, partly offset by 
  stronger sales in Europe. 
  Shingles 
  Shingrix recorded sales of GBP563 million in the first nine months 
  in the US and Canada, driven by demand and share gains. US sales 
  benefited from market growth in new patient populations now covered 
  by immunisation recommendations. 
  Established Vaccines 
  Sales of DTPa-containing vaccines (Infanrix, Pediarix and Boostrix) 
  were down 12% AER, 9% CER. Boostrix sales declined 11% AER, 8% CER 
  to GBP378 million, primarily driven by lower demand in International 
  and the return to the market of a competitor in Europe. Infanrix, 
  Pediarix sales were down 12% AER, 9% CER to GBP515 million, reflecting 
  increased competitive pressures in Europe and the US as well as unfavourable 
  year-on-year CDC stockpile movements in the US, partly offset by 
  stronger demand in International. 
  Hepatitis vaccines grew 16% AER, 20% CER to GBP618 million, benefiting 
  from a competitor supply shortage and stronger demand in the US and 
  Europe, partly offset by unfavourable CDC stockpile movements in 
  the US. 
  Rotarix sales were down 3% AER and flat at CER to GBP387 million. 
  Synflorix sales declined 20% AER and 20% CER to GBP318 million, primarily 
  impacted by lower pricing and demand in Emerging Markets. 
  Cervarix sales increased 71% AER, 74% CER to GBP123 million, primarily 
  driven by its recent launch in China.

 Consumer Healthcare sales in the nine months declined 2% AER but 
  grew 2% CER to GBP5,750 million, with continued broad-based growth 
  in Oral health partly offset by a decline in Panadol and lower sales 
  of tail brands. 
  The aggregate impact from generic competition on Transderm Scop in 
  the US, the divestment of a number of tail brands, including Horlicks 
  and MaxiNutrition in the UK, and implementation of the Goods & Service 
  Tax (GST) in India on overall growth was around one percentage point. 
  Wellness 
  Wellness sales declined 2% AER but grew 2% CER to GBP2,935 million. 
  Voltaren grew in mid-single digits due to new launches while Theraflu 
  growth was supported by a strong cold and flu season earlier in the 
  year. Panadol delivered a weaker performance as a result of the change 
  in the route-to-market model in South-East Asia and the discontinuation 
  of slow-release Panadol products in the Nordic countries. 
 
  Oral health 
  Oral health sales were flat at AER but grew 5% CER to GBP1,873 million, 
  as Sensodyne delivered high single-digit growth in the US and a number 
  of International markets, driven by Sensodyne Rapid, partly offset 
  by destocking in China. Denture care grew in high single digits through 
  a strong Poligrip performance in the US and the launch of Corega 
  Max in Russia. 
  Nutrition 
  Nutrition sales declined 5% AER but grew 2% CER to GBP489 million. 
  The Nutrition business in India performed strongly across the product 
  portfolio, benefiting from new innovations including Horlicks Protein+ 
  which was launched earlier in the year. The impact of divestments 
  and India GST implementation on Nutrition growth was approximately 
  nine percentage points. 
 
  Skin health 
  Skin health sales were down 3% AER but flat at CER at GBP453 million, 
  with high single-digit growth in Fenistil offset by a decline in 
  tail brands.

 Cost of sales 
  Cost of sales as a percentage of turnover was 32.6%, down 1.2 percentage 
  points at AER and 1.7 percentage points in CER terms compared with 
  Q3 2017. This primarily reflected the phasing of costs of manufacturing 
  restructuring programmes, as well as the comparison with a number 
  of non-cash write downs in Q3 2017 as a result of plant closures, 
  together with a more favourable product mix in all three businesses, 
  particularly the impact of higher Vaccines and HIV sales, and a further 
  contribution from integration and restructuring savings in all three 
  businesses. This was partly offset by continued adverse pricing pressure 
  in Pharmaceuticals, particularly in Respiratory and Established Vaccines, 
  inventory adjustments and increased input costs. 
  Selling, general and administration 
  SG&A costs as a percentage of turnover were 31.2%, 1.8 percentage 
  points higher than in Q3 2017 at AER and 1.9 percentage points higher 
  on a CER basis. This reflected a 12% increase, at CER, in SG&A costs 
  compared with Q3 2017 due to increased restructuring costs mainly 
  in the Pharmaceuticals business as well as increased investment in 
  promotional product support, particularly for new launches in Vaccines, 
  Respiratory and HIV and targeted priority markets, partly offset 
  by tight control of ongoing costs, particularly in non-promotional 
  and back office spending across all three businesses. 
  Research and development 
  R&D expenditure was GBP988 million (12.2% of turnover), down 6% AER, 
  5% CER, primarily reflecting lower restructuring costs, particularly 
  in comparison to the charges in Q3 2017 related to the termination 
  of rights to sirukumab and the benefits of the re-prioritisation 
  of the R&D portfolio. This was partly offset by increased investment 
  in the progression of a number of mid and late-stage programmes, 
  particularly in Oncology and provision for the costs payable to a 
  third party relating to the expected use of a Priority Review Voucher. 
  Royalty income 
  Royalty income was GBP94 million (Q3 2017: GBP107 million), down 
  12% AER, 13% CER, primarily reflecting the patent expiry of Cialis. 
  Other operating income/(expense) 
  Net other operating expense of GBP125 million (Q3 2017: GBP66 million) 
  reflected GBP248 million (Q3 2017: GBP19 million) of accounting charges 
  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. The largest element was a re-measurement of GBP214 
  million for the contingent consideration liability due to Shionogi, 
  primarily arising from changes in exchange rate assumptions. This 
  was partly offset by the profit on a number of asset disposals, including 
  tapinarof. 
  Operating profit 
  Total operating profit was GBP1,910 million in Q3 2018 compared with 
  an operating profit of GBP1,877 million in Q3 2017. The increase 
  in operating profit primarily reflected the benefit from sales growth 
  in all three businesses, a more favourable mix and continued tight 
  control of ongoing costs across all three businesses, as well as 
  profit on a number of asset disposals, including tapinarof. This 
  was partly offset by the increased impact of accounting charges related 
  to re-measurement of the liabilities for contingent consideration, 
  put options and preferential dividends, as well as increased restructuring 
  costs, compared with Q3 2017. Operating profit was also impacted 
  by continuing price pressure, particularly in Respiratory, supply 
  chain investments, increased R&D investment including a provision 
  for the costs expected to be payable to a third party relating to 
  the future use of a Priority Review Voucher, investments in promotional 
  product support, particularly for new launches in Vaccines, Respiratory 
  and HIV, and a reduction in royalty income. 
  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 the quarter amounted to GBP213 million (Q3 2017: 
  GBP189 million). This included cash payments made to Shionogi of 
  GBP208 million (Q3 2017: GBP186 million). 
  Net finance costs 
  Net finance expense was GBP223 million compared with GBP181 million 
  in Q3 2017. The increase primarily reflected higher debt following 
  the acquisition from Novartis of its stake in the Consumer Healthcare 
  Joint Venture in June 2018 as well as additional interest on a historic 
  tax settlement. 
  Taxation 
  The charge of GBP193 million represented an effective tax rate of 
  11.3% (Q3 2017: 18.5%) and reflected the differing tax effects of 
  the various adjusting items, including the reassessment of estimates 
  of uncertain tax positions following the settlement of a number of 
  open issues with tax authorities in key jurisdictions. 
  Non-controlling interests 
  The allocation of earnings to non-controlling interests amounted 
  to GBP94 million (Q3 2017: GBP183 million). The reduction in allocation 
  was primarily due to the ending of allocations of Consumer Healthcare 
  profits (Q3 2017: GBP77 million) following the buyout of Novartis' 
  interest in Q2 2018, and a lower allocation of ViiV Healthcare profits 
  of GBP78 million (Q3 2017: GBP100 million), including the impact 
  of changes in the proportions of preferential dividends due to each 
  shareholder based on the relative performance of different products 
  in the quarter and higher remeasurement charges. This was partly 
  offset by an increased allocation due to higher net profits in some 
  of the Group's other entities with non-controlling interests. 
  Earnings per share 
  Total earnings per share was 28.8p, compared with 24.8p in Q3 2017. 
  The increase in earnings per share primarily reflected increased 
  profit on disposals as well as an improved trading performance, reduced 
  non-controlling interest allocation of Consumer Healthcare profits 
  and a reduced tax rate. This was partly offset by the impact of charges 
  arising from increases in the valuation of the liabilities for contingent 
  consideration, put options and preferential dividends. 
 
 
 Adjusting items 
  GSK presents Total results and Adjusted results in order to assist 
  shareholders in better understanding the Group's operational performance. 
  Adjusted results, which is a non-IFRS measure, may be considered 
  in addition to, but not as a substitute for, or superior to, information 
  presented in accordance with IFRS. 
  Total results represent the Group's overall performance. However, 
  these results can contain material unusual or non-operational items 
  that may obscure the key trends and factors determining the Group's 
  operational performance. As a result, GSK also reports Adjusted results. 
  GSK believes that Adjusted results allow the key trends and factors 
  driving the Group's performance to be more easily and clearly identified 
  by shareholders. This approach also aligns Group's results with the 
  majority of its peer companies and how they report earnings. 
  Adjusted results exclude the following items from Total results: 
  amortisation and impairments of intangible assets and goodwill; major 
  restructuring costs (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 those integration 
  costs following material acquisitions; significant legal charges 
  (net of insurance recoveries) and expenses on the settlement of litigation 
  and government investigations; transaction-related accounting adjustments 
  for significant acquisitions, and other items, including; disposals 
  of associates, products and businesses and other operating income 
  other than royalty income, together with the tax effects of all of 
  these items and the impact of the enactment of the US Tax Cuts and 
  Jobs Act in 2017. Costs for all other ordinary course smaller scale 
  restructuring and legal charges and expenses are retained within 
  Total and Adjusted results. 
  The adjusting items that reconcile Total operating profit, profit 
  after tax and earnings per share to Adjusted results are as follows:

 Full reconciliations between Total results and Adjusted results are 
  set out on pages 58 to 61 and the definition of Adjusted results 
  is set out on page 37. 
 
 
 Intangible asset amortisation and impairment 
  Intangible asset amortisation was GBP143 million, compared with GBP149 
  million in Q3 2017. There were also intangible asset impairments 
  of GBP49 million (Q3 2017: GBP82 million) reflecting a number of 
  impairments to commercial and R&D assets. Both of these charges were 
  non-cash items. 
 
 
 Major restructuring and integration 
  Major restructuring costs related to specific Board approved Major 
  restructuring 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, 
  are excluded from Adjusted results. Other ordinary course smaller 
  scale restructuring costs are retained within Total and Adjusted 
  results. 
  The Board approved a new major restructuring programme in July 2018, 
  which is designed to significantly improve the competitiveness and 
  efficiency of the Group's cost base with savings delivered primarily 
  through supply chain optimisation and reductions in administrative 
  costs. 
  Total Major restructuring and integration charges incurred in the 
  quarter were GBP283 million (Q3 2017: GBP266 million). These included 
  GBP155 million under the existing combined integration programme 
  (Q3 2017: GBP266 million) and GBP128 million relating to the 2018 
  major restructuring programme. Total non-cash charges were GBP19 
  million (Q3 2017: GBP77 million) all arising under the existing combined 
  integration programme and primarily relating to the write-down of 
  assets largely as a result of announced plans to reduce the manufacturing 
  network. Total cash charges were GBP264 million, including GBP136 
  million under the existing combined programme (Q3 2017: GBP189 million) 
  relating to restructuring in the Europe and International Pharmaceuticals 
  commercial operations as well as some manufacturing sites, and GBP128 
  million under the 2018 major restructuring programme, primarily relating 
  to restructuring in the US Pharmaceuticals commercial operation. 
  Cash payments made in the quarter were GBP140 million (Q3 2017: GBP117 
  million) including the settlement of certain charges accrued in previous 
  quarters. The existing combined programme delivered incremental annual 
  cost savings in the quarter of less than GBP0.1 billion. 
  Transaction-related adjustments 
  Transaction-related adjustments resulted in a net charge of GBP247 
  million (Q3 2017: GBP40 million). This primarily reflected GBP248 
  million of accounting charges 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 GBP214 million charge relating to the contingent consideration 
  for the former Shionogi-ViiV Healthcare Joint Venture represented 
  GBP101 million arising primarily from updated exchange rate assumptions, 
  together with a GBP113 million unwind of the discount. A credit of 
  GBP21 million relating to a decrease in the put option liability 
  to Pfizer reflected revised exchange rate assumptions on forecasts 
  as well as adjustments to pipeline forecasts. 
  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 the quarter amounted to GBP213 million (Q3 2017: 
  GBP189 million). This included cash payments made by ViiV Healthcare 
  to Shionogi in relation to its contingent consideration liability 
  (including preferential dividends) which amounted to GBP208 million 
  (Q3 2017: GBP186 million). 
  An explanation of the accounting for the non-controlling interests 
  in ViiV Healthcare is set out on page 56. 
  Divestments, significant legal charges and other items 
  Divestments and other items included the profit on a number of asset 
  disposals, including tapinarof, equity investment impairments and 
  certain other adjusting items. A charge of GBP12 million (Q3 2017: 
  GBP1 million credit) for significant legal matters included the benefit 
  of the settlement of existing matters as well as provisions for ongoing 
  litigation. Significant legal cash payments were GBP12 million (Q3 
  2017: GBP137 million).

 *   Operating profit of Pharmaceuticals R&D segment, which is the responsibility 
      of the President, Pharmaceuticals R&D. It excludes ViiV Healthcare 
      operating profit, which is reported within the Pharmaceuticals 
      segment. A more detailed breakdown of R&D expenses is set out on 
      page 33. 
 
 
 Operating profit 
  Adjusted operating profit was GBP2,524 million, 2% higher than Q3 
  2017 at AER and 6% higher at CER on a turnover increase of 6% CER. 
  The Adjusted operating margin of 31.2% was 0.3 percentage points 
  lower at AER but 0.2 percentage points higher on a CER basis than 
  in Q3 2017. This primarily reflected the benefit from sales growth 
  in all three businesses, a more favourable mix and continued tight 
  control of ongoing costs across all three businesses. This was partly 
  offset by continuing price pressure, particularly in Respiratory, 
  supply chain investments, increased R&D investment including the 
  provision for costs expected to be payable to a third party relating 
  to the future use of a Priority Review Voucher, investments in promotional 
  product support, particularly for new launches in Vaccines, Respiratory 
  and HIV, as well as a reduction in royalty income. 
  Cost of sales 
  Cost of sales as a percentage of turnover was 29.5%, up 0.1 percentage 
  points at AER, but down 0.3 percentage points at CER compared with 
  Q3 2017. This primarily reflected a more favourable product mix in 
  all three businesses, particularly the impact of higher Vaccines 
  and HIV sales, and a further contribution from integration and restructuring 
  savings in all three businesses. This was partly offset by continued 
  adverse pricing pressure in Pharmaceuticals, particularly in Respiratory 
  and Established Vaccines, inventory adjustments and increased input 
  costs. 
  Selling, general and administration 
  SG&A costs as a percentage of turnover were 28.6%, 0.5 percentage 
  points lower at AER than in Q3 2017 and 0.5 percentage points lower 
  on a CER basis. The 1% AER, 4% CER increase in SG&A costs primarily 
  reflected increased investment in promotional product support, particularly 
  for new launches in Vaccines, Respiratory and HIV and targeted priority 
  markets partly offset by tight control of ongoing costs, particularly 
  in non-promotional spending across all three businesses. 
  Research and development 
  R&D expenditure was GBP961 million (11.9% of turnover), 7% AER, 8% 
  CER higher than Q3 2017, primarily reflecting increased investment 
  in the progression of a number of mid and late-stage programmes, 
  particularly in Oncology as well as the provision for costs expected 
  to be payable to a third party relating to the future use of a Priority 
  Review Voucher partly offset by the benefits of the re-prioritisation 
  of the R&D portfolio. 
  Royalty income 
  Royalty income was GBP94 million (Q3 2017: GBP107 million), a reduction 
  of 12% AER, 13% CER, primarily reflecting the patent expiry of Cialis. 
  Operating profit by business 
  Pharmaceuticals operating profit was GBP1,361 million, down 5% AER, 
  2% CER on a turnover increase of 3% CER. The operating margin of 
  32.2% was 1.8 percentage points lower at AER than in Q3 2017 and 
  1.6 percentage points lower on a CER basis. This primarily reflected 
  increased R&D investment including the costs payable to a third party 
  relating to the future use of a Priority Review Voucher awarded in 
  Q3 2018, investment in new product support and targeted priority 
  markets, as well as the continued impact of lower prices, particularly 
  in Respiratory, and the reduction in royalty income, partly offset 
  by a more favourable product mix, primarily driven by the growth 
  in HIV sales. 
 
  Vaccines operating profit was GBP827 million, 18% higher than Q3 
  2017 at AER and 26% higher at CER on a turnover increase of 17% CER. 
  The operating margin of 43.0% was 1.7 percentage points higher than 
  in Q3 2017 at AER and 3.2 percentage points higher on a CER basis. 
  This was primarily driven by enhanced operating leverage from strong 
  sales growth, improved product mix and higher royalty income, partly 
  offset by inventory adjustments and increased SG&A resources to support 
  new launches and business growth. 
 
  Consumer Healthcare operating profit was GBP429 million, up 9% AER, 
  16% CER, on a turnover increase of 3% CER. The operating margin of 
  22.0% was 2.0 percentage points higher than in Q3 2017 at AER, and 
  2.5 percentage points higher on a CER basis. This primarily reflected 
  continued manufacturing restructuring and integration benefits and 
  improved product mix as well as tight control of promotional and 
  other operating expenses compared with Q3 2017. 
  Net finance costs 
  Net finance expense was GBP221 million compared with GBP177 million 
  in Q3 2017. The increase primarily reflected higher debt following 
  the acquisition from Novartis of its stake in the Consumer Healthcare 
  Joint Venture in June 2018 as well as additional interest of GBP23 
  million on a historic tax settlement. 
  Taxation 
  Tax on Adjusted profit amounted to GBP430 million and represented 
  an effective Adjusted tax rate of 18.6% (Q3 2017: 21.0%). See 'Taxation' 
  on page 51 for further details. 
 
  Non-controlling interests 
  The allocation of Adjusted earnings to non-controlling interests 
  amounted to GBP141 million (Q3 2017: GBP228 million). The reduction 
  in allocation was primarily due to the ending of non-controlling 
  interest allocations of Consumer Healthcare profits (Q3 2017: GBP105 
  million) following the buyout of Novartis' interest in Q2 2018. This 
  was partly offset by increases in the allocation of ViiV Healthcare 
  profits of GBP125 million (Q3 2017: GBP117 million), including the 
  impact of changes in the proportions of preferential dividends due 
  to each shareholder based on the relative performance of different 
  products in the quarter, as well as increases in the allocation to 
  non-controlling interests due to higher net profits in some of the 
  Group's other entities with non-controlling interests. 
 
  Earnings per share 
  Adjusted EPS of 35.5p was up 10% AER, 14% CER, compared with a 6% 
  CER increase in Adjusted operating profit, primarily as a result 
  of the reduced non-controlling interest allocation of Consumer Healthcare 
  profits and a reduced Adjusted tax rate. 
 
 
 Currency impact on Q3 2018 results 
  The Q3 2018 results are based on average exchange rates, principally 
  GBP1/$1.31, GBP1/EUR1.11 and GBP1/Yen 146. Comparative exchange rates 
  are given on page 52. The period-end exchange rates were GBP1/$1.30, 
  GBP1/EUR1.12 and GBP1/Yen 148. 
  In the quarter, turnover increased 3% AER, 6% CER. Total EPS was 
  28.8p compared with 24.8p in Q3 2017 and Adjusted EPS was 35.5p compared 
  with 32.5p in Q3 2017, up 10% AER, 14% CER. The negative currency 
  impact primarily reflected the strength of Sterling, particularly 
  against the US Dollar and Emerging Market currencies, relative to 
  Q3 2017. Exchange gains or losses on the settlement of intercompany 
  transactions had a negligible impact on the negative currency impact 
  of four percentage points on Adjusted EPS.

 Cost of sales 
  Cost of sales as a percentage of turnover was 32.4%, down 2.1 percentage 
  points at AER and 2.8 percentage points in CER terms compared with 
  2017. This primarily reflected a favourable comparison with GBP363 
  million of non-cash write-downs of assets in 2017 related to the 
  decision to withdraw Tanzeum progressively. The nine months also 
  benefited from a more favourable product mix in all three businesses, 
  particularly the impact of higher HIV sales and the launch of Shingrix, 
  together with a further contribution from integration and restructuring 
  savings. This was partly offset by an adverse comparison with the 
  benefit of a settlement for lost third party supply volume in 2017 
  in Vaccines, as well as continued adverse pricing pressure in Pharmaceuticals, 
  particularly in Respiratory and Established Vaccines, and increased 
  input costs. 
  Selling, general and administration 
  SG&A costs as a percentage of turnover were 32.2%, 0.5 percentage 
  points higher than in 2017 at AER and 0.5 percentage points higher 
  on a CER basis. This reflected a 6% increase, at CER, in SG&A costs 
  compared with 2017 primarily due to increased restructuring and integration 
  costs, as well as increased investment in promotional product support, 
  particularly for new launches in Respiratory, HIV and Vaccines, partly 
  offset by tight control of ongoing costs, particularly in non-promotional 
  and back office spending across all three businesses. 
  Research and development 
  R&D expenditure was GBP2,817 million (12.5% of turnover), 14% AER, 
  11% CER lower than in 2017. This reflected a favourable comparison 
  with the impact of the Priority Review Voucher in 2017, as well as 
  reduced restructuring costs primarily due to the comparison with 
  the provision for obligations as a result of the decision to withdraw 
  Tanzeum progressively in Q3 2017 and the benefit of the R&D prioritisation 
  initiatives started in the second half of last year. This was partly 
  offset by increased investment in the progression of a number of 
  mid and late-stage programmes, particularly in Oncology, as well 
  as provisions for the costs payable to a third party relating to 
  the expected use of a Priority Review Voucher awarded in 2018. 
  Royalty income 
  Royalty income was GBP220 million (2017: GBP287 million), down 23% 
  AER and CER, the reduction primarily reflecting the patent expiry 
  of Cialis. 
  Other operating income/(expense) 
  Net other operating expense of GBP1,466 million (2017: GBP1,069 million) 
  primarily reflected GBP1,617 million (2017: GBP1,299 million) of 
  accounting charges 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, the value attributable to the Consumer Healthcare Joint 
  Venture put option previously held by Novartis and the liabilities 
  for the Pfizer put option and Pfizer and Shionogi preferential dividends 
  in ViiV Healthcare. This was partly offset by the profit on a number 
  of asset disposals, including tapinarof. 
  The accounting charges were driven primarily by a GBP927 million 
  re-measurement of the contingent consideration liability due to Shionogi, 
  primarily related to changes in exchange rate assumptions and sales 
  forecasts following the GEMINI study completed in Q2 2018. In addition, 
  a net charge of GBP658 million reflected the re-measurement of the 
  valuation of the Consumer Healthcare put option, together with movements 
  in exchange rates largely offset by gains on hedging contracts. 
  Operating profit 
  Total operating profit was GBP3,929 million in the nine months compared 
  with GBP3,575 million in 2017. The increase in operating profit primarily 
  reflected reduced restructuring costs and asset impairments in comparison 
  with the non-cash charges in 2017 relating to the progressive withdrawal 
  of Tanzeum. In addition, there was a contribution from sales growth 
  on a CER basis in all three businesses, a more favourable mix, benefits 
  from prioritisation of R&D expenditure and comparison with the impact 
  of the Priority Review Voucher utilised and expensed in 2017 and 
  continued tight control of ongoing costs. This was partly offset 
  by continuing price pressure, particularly in Respiratory, supply 
  chain investments, the comparison with the benefit in Q2 2017 of 
  a settlement for lost third party supply volume in Vaccines and investments 
  in new product support, particularly for launches in Respiratory, 
  HIV and Vaccines, as well as a reduction in royalty income. 
 
  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 the nine months amounted to GBP915 million (2017: 
  GBP492 million). This included a cash milestone paid to Novartis 
  of $450 million (GBP317 million) as well as cash payments made to 
  Shionogi of GBP584 million (2017: GBP485 million). 
 
  Net finance costs 
  Net finance expense was GBP532 million compared with GBP531 million 
  in 2017. This reflected higher debt following the acquisition from 
  Novartis of its stake in the Consumer Healthcare Joint Venture in 
  June 2018 as well as additional interest on a historic tax settlement 
  in Q3 2018, offset by the benefit of a one-off accounting adjustment 
  to the amortisation of long term bond interest charges of GBP20 million 
  in Q1 2018, the maturity of older bonds refinanced at lower interest 
  rates as well as the translation impact of exchange rate movements 
  on the reported Sterling costs of foreign currency denominated interest-bearing 
  instruments. 
 
  Taxation 
  The charge of GBP680 million represented an effective tax rate of 
  19.8% (2017: 17.9%) and reflected the differing tax effects of the 
  various adjusting items. 
 
  Non-controlling interests 
  The allocation of earnings to non-controlling interests amounted 
  to GBP338 million (2017: GBP454 million). The reduction in allocation 
  was primarily due to the ending of further non-controlling interest 
  allocation of Consumer Healthcare profits of GBP117 million (2017: 
  GBP197 million) after 3 May 2018 when the buyout of Novartis' interest 
  became unconditional, as well as a lower allocation of ViiV Healthcare 
  profits of GBP175 million (Q3 2017: GBP226 million), including the 
  impact of the impact of re-measurement charges and changes in the 
  proportions of preferential dividends due to each shareholder. This 
  was partly offset by an increased allocation to non-controlling interests 
  due to higher net profits in some of the Group's other entities with 
  non-controlling interests. 
 
  Earnings per share 
  Total earnings per share was 49.0p, compared with 42.5p in 2017. 
  The increase in earnings per share primarily reflected an increase 
  in Adjusted operating profit, reduced restructuring costs and asset 
  impairments in comparison with the non-cash charges in 2017 relating 
  to the progressive withdrawal of Tanzeum and a reduced non-controlling 
  interest allocation of Consumer Healthcare profits. This was partly 
  offset by the impact of charges arising from increases in the valuation 
  of the liabilities for contingent consideration, put options and 
  preferential dividends. 
 
 
 Adjusting items 
  GSK presents Total results and Adjusted results in order to assist 
  shareholders in better understanding the Group's operational performance. 
  Adjusted results, which is a non-IFRS measure, may be considered 
  in addition to, but not as a substitute for, or superior to, information 
  presented in accordance with IFRS. 
  Total results represent the Group's overall performance. However, 
  these results can contain material unusual or non-operational items 
  that may obscure the key trends and factors determining the Group's 
  operational performance. GSK therefore also reports Adjusted results 
  to help shareholders identify and assess more clearly the Group's 
  performance. This approach also aligns the presentation of the Group's 
  results more closely with the majority of GSK's peer group. 
  Adjusted results exclude the following items from Total results: 
  amortisation and impairments of intangible assets and goodwill; major 
  restructuring costs (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; significant legal charges 
  and expenses; transaction-related accounting adjustments; disposals 
  and other operating income other than royalty income, together with 
  the tax effects of all of these items and the impact of the implementation 
  of the US Tax Cuts and Jobs Act in 2017. Costs for all other ordinary 
  course smaller scale restructuring and legal charges and expenses 
  are retained within the Adjusted results. 
  The adjusting items that reconcile Total operating profit, profit 
  after tax and earnings per share to Adjusted results are as follows:

 Full reconciliations between Total results and Adjusted results are 
  set out on pages 58 to 61 and the definition of Adjusted results 
  is set out on page 37. 
 
 
 Intangible asset amortisation and impairment 
  Intangible asset amortisation was GBP430 million, compared with GBP444 
  million in 2017. There were also lower intangible asset impairments 
  of GBP104 million (2017: GBP421 million) related to commercial and 
  Pharmaceuticals R&D development assets, reflecting a favourable comparison 
  with 2017 which included an impairment related to the progressive 
  withdrawal of Tanzeum and a number of other impairments to commercial 
  assets. Both of these charges were non-cash items. 
 
 
 Major restructuring and integration 
  Major restructuring costs related to specific Board approved Major 
  restructuring 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, 
  are excluded from Adjusted results. Other ordinary course smaller 
  scale restructuring costs are retained within Total and Adjusted 
  results. 
  The Board approved in July 2018 a new major restructuring programme, 
  which is designed to significantly improve the competitiveness and 
  efficiency of the Group's cost base with savings delivered primarily 
  through supply chain optimisation and reductions in administrative 
  costs. 
  Total Major restructuring and integration charges incurred in the 
  nine months were GBP506 million (2017: GBP872 million). These included 
  GBP378 million under the existing combined integration programme 
  and GBP128 million relating to the 2018 major restructuring programme. 
  Total non-cash charges were GBP100 million (2017: GBP375 million) 
  all under the existing combined integration programme primarily relating 
  to write down of assets in manufacturing sites. Total cash charges 
  were GBP406 million (2017: GBP497 million), including GBP278 million 
  under the existing combined programme, primarily relating to restructuring 
  in Europe and International Pharmaceuticals commercial operations, 
  as well as some manufacturing sites and GBP128 million under the 
  new 2018 programme, primarily relating to restructuring in the US 
  Pharmaceuticals commercial operation. Cash payments made in the nine 
  months were GBP353 million (2017: GBP449 million) including the settlement 
  of certain charges accrued in previous quarters. The programmes delivered 
  incremental annual cost savings in the nine months of GBP0.2 billion. 
  Charges for the existing combined restructuring and integration programme 
  to date are GBP5.1 billion, of which cash charges were GBP3.7 billion. 
  Cash payments of GBP3.5 billion have been made to date. Non-cash 
  charges were GBP1.4 billion. 
  Estimated charges for 2018 under the existing combined restructuring 
  and integration programme are GBP0.5 billion, with cash charges of 
  around GBP0.3 billion and non-cash charges of around GBP0.2 billion. 
  Total cash charges for the combined restructuring and integration 
  programme are now expected to be approximately GBP4.1 billion with 
  non-cash charges up to GBP1.6 billion. The programme has now delivered 
  approximately GBP3.9 billion of annual savings, including a currency 
  benefit of GBP0.4 billion. The programme is now expected to deliver 
  by 2020 total annual savings of GBP4.0 billion on a constant currency 
  basis, together with an estimated benefit of GBP0.4 billion from 
  currency on the basis of September 2018 average exchange rates. 
  The 2018 programme is expected to cost GBP1.7 billion over the period 
  to 2021, with cash costs of GBP0.8 billion and non-cash costs of 
  GBP0.9 billion, and is expected to deliver annual savings of around 
  GBP400 million by 2021 (at 2018 rates). These savings will be fully 
  re-invested in the Group to help fund targeted increases in R&D and 
  commercial support of new products. 
  Estimated charges under the new programme for 2018 are GBP0.4 billion, 
  with cash charges of around GBP0.3 billion and non-cash charges of 
  around GBP0.1 billion. 
  Transaction-related adjustments 
  Transaction-related adjustments resulted in a net charge of GBP1,706 
  million (2017: GBP1,358 million). This primarily reflected GBP1,617 
  million of accounting charges 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, the value attributable to the Consumer Healthcare Joint 
  Venture put option held by Novartis and the liabilities for the Pfizer 
  put option and Pfizer and Shionogi preferential dividends in ViiV 
  Healthcare.

 A net charge of GBP658 million relating to the Consumer Healthcare 
  Joint Venture represented the re-measurement of the valuation of 
  the Consumer Healthcare put option to the agreed undiscounted valuation 
  of $13 billion (GBP9.2 billion on signing), together with an increase 
  due to movements in exchange rates, largely offset by gains on hedging 
  contracts. 
  The GBP927 million charge taken relating to the contingent consideration 
  for the former Shionogi-ViiV Healthcare Joint Venture represented 
  a GBP613 million increase in the valuation of the contingent consideration 
  due to Shionogi, primarily as a result of updated exchange rate assumptions 
  and sales forecasts following the GEMINI study completed in Q2 2018, 
  together with a GBP314 million unwind of the discount. 
  Other adjustments included a GBP61 million charge reflecting the 
  release of an indemnity asset relating to the tax treatment of inventory 
  acquired as part of the Novartis Vaccines acquisition, with a corresponding 
  offset in tax. 
  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 the nine months amounted to GBP915 million (2017: 
  GBP492 million). This included a cash milestone paid to Novartis 
  of $450 million (GBP317 million) as well as cash payments made by 
  ViiV Healthcare to Shionogi in relation to its contingent consideration 
  liability (including preferential dividends) which amounted to GBP584 
  million (2017: GBP485 million). 
  An explanation of the accounting for the non-controlling interests 
  in ViiV Healthcare is set out on page 56. 
  Divestments, significant legal charges and other items 
  Divestments and other items included the profit on a number of asset 
  disposals, including tapinarof, equity investment impairments and 
  certain other adjusting items. A charge of GBP29 million (2017: GBP60 
  million) for significant legal matters included the benefit of the 
  settlement of existing matters as well as provisions for ongoing 
  litigation. Significant legal cash payments were GBP24 million (2017: 
  GBP184 million). 
 
 
 Adjusted results 
  GSK uses Adjusted results, which is a non-IFRS measure, to report 
  the performance of the Group, as it believes that it allows the key 
  trends and factors in the Group's performance to be more easily and 
  clearly identified. Non-IFRS measures may be considered in addition 
  to, but not as a substitute for or superior to, information presented 
  in accordance with IFRS.

      page 33. 
 
 
 Operating profit 
  Adjusted operating profit was GBP6,549 million, flat at AER compared 
  with 2017 but 7% CER higher on a turnover increase of 4%. The Adjusted 
  operating margin of 28.9% was 0.1 percentage points lower at AER 
  than in 2017 but 0.7 percentage points higher on a CER basis. This 
  reflected the benefit from sales growth in all three businesses, 
  a more favourable mix, the benefits of prioritisation of R&D expenditure 
  and the comparison with the impact of the Priority Review Voucher 
  utilised and expensed in 2017 as well as continued tight control 
  of ongoing costs across all three businesses. This was partly offset 
  by continuing price pressure, particularly in Respiratory, supply 
  chain investments, the comparison with the benefit in Q2 2017 of 
  a settlement for lost third party supply volume in Vaccines and investments 
  in promotional product support, particularly for new launches in 
  Respiratory, HIV and Vaccines, as well as a reduction in royalty 
  income. 
  Cost of sales 
  Cost of sales as a percentage of turnover was 29.4%, up 0.5 percentage 
  points at AER, but down 0.1 percentage points in CER terms compared 
  with 2017. This primarily reflected a more favourable product mix 
  in all three businesses, particularly the impact of higher HIV sales 
  and the launch of Shingrix, as well as a further contribution from 
  integration and restructuring savings in all three businesses, offset 
  by an adverse comparison with the benefit of a settlement for lost 
  third party supply volume in 2017 in Vaccines, as well as continued 
  adverse pricing pressure in Pharmaceuticals, particularly in Respiratory, 
  and in Established Vaccines, and increased input costs. 
  Selling, general and administration 
  SG&A costs as a percentage of turnover were 30.6%, 0.1 percentage 
  points lower at AER than in 2017 and 0.1 percentage points lower 
  on a CER basis. The 4% CER increase primarily reflected increased 
  investment in promotional product support, particularly for new launches 
  in Respiratory, HIV and Vaccines, offset by tight control of ongoing 
  costs, particularly in non-promotional spending across all three 
  businesses. 
  Research and development 
  R&D expenditure was GBP2,716 million (12.0% of turnover), 5% AER, 
  3% CER lower than 2017, primarily reflecting the comparison with 
  the impact of the Priority Review Voucher in H1 2017, as well as 
  the benefit of the prioritisation initiatives started in the second 
  half of 2017. This was partly offset by increased investment in the 
  progression of a number of mid and late-stage programmes, particularly 
  in Oncology, as well as the provision for costs expected to be payable 
  to a third party relating to the future use of a Priority Review 
  Voucher awarded in 2018. 
  Royalty income 
  Royalty income was GBP220 million (2017: GBP287 million), primarily 
  reflecting the patent expiry of Cialis. 
  Operating profit by business 
  Pharmaceuticals operating profit was GBP4,182 million, down 3% AER 
  but up 2% CER on a turnover increase of 2% CER. The operating margin 
  of 33.6% was 0.4 percentage points lower at AER than in 2017 but 
  flat on a CER basis. This primarily reflected the favourable comparison 
  with the impact of the Priority Review Voucher in 2017, as well as 
  a more favourable product mix, primarily driven by the growth in 
  HIV sales, as well as benefits of prioritisation within R&D. This 
  was offset by increased investment in new product support, the continued 
  impact of lower prices, particularly in Respiratory, and the broader 
  transition of the Respiratory portfolio, the cost payable to a third 
  party relating to the future use of a Priority Review Voucher awarded 
  in 2018 as well as a reduction in royalty income. 
 
  Vaccines operating profit was GBP1,523 million, 8% AER, 18% CER higher 
  than in 2017 on a turnover increase of 15% CER. The operating margin 
  of 34.5% was 1.3 percentage points lower at AER than in 2017 but 
  0.7 percentage points higher on a CER basis. This was primarily driven 
  by an improved product mix including the launch of Shingrix, together 
  with further restructuring and integration benefits. This was partly 
  offset by the comparison with the benefit of a settlement for lost 
  third party supply volume recorded in 2017, increased supply chain 
  costs and increased SG&A resources to support new launches and business 
  growth. 
 
  Consumer Healthcare operating profit was GBP1,165 million, up 9% 
  AER, 15% CER on a turnover increase of 2% CER. The operating margin 
  of 20.3% was 2.0 percentage points higher than in 2017 and 2.3 percentage 
  points higher on a CER basis. This primarily reflected continued 
  manufacturing restructuring and integration benefits, improved product 
  mix as well as continued tight control of promotional and other operating 
  expenses. 
  Net finance costs 
  Net finance expense was GBP525 million compared with GBP522 million 
  in 2017. The increase reflected higher debt following the acquisition 
  from Novartis of its stake in the Consumer Healthcare Joint Venture 
  in June 2018 as well as additional interest of GBP23 million on a 
  historic tax settlement in Q3 2018, partly offset by the benefit 
  of a one-off accounting adjustment to the amortisation of long term 
  bond interest charges of GBP20 million in Q1 2018, the maturity of 
  older bonds refinanced at lower interest rates as well as the translation 
  impact of exchange rate movements on the reported Sterling costs 
  of foreign currency denominated interest-bearing instruments. 
  Taxation 
  Tax on Adjusted profit amounted to GBP1,180 million and represented 
  an effective Adjusted tax rate of 19.5% (2017: 21.4%). See 'Taxation' 
  on page 51 for further details. 
 
  Non-controlling interests 
  The allocation of Adjusted earnings to non-controlling interests 
  amounted to GBP535 million (2017: GBP601 million). The reduction 
  in allocation of GBP118 million (2017: GBP259 million) was primarily 
  due to the ending of non-controlling interest allocation of Consumer 
  Healthcare profits after 3 May 2018 when the buyout of Novartis' 
  interest became unconditional. This was partly offset by increases 
  in the allocation of ViiV Healthcare profits of GBP371 million (Q3 
  2017: GBP311 million), and the changes in the proportions of preferential 
  dividends due to each shareholder based on the relative performance 
  of different products, as well as increases in the allocation to 
  non-controlling interests due to higher net profits in some of the 
  Group's other entities with non-controlling interests. 
 
  Earnings per share 
  Adjusted EPS of 88.3p was up 4% AER, 12% CER, compared with a 7% 
  CER increase in Adjusted operating profit, primarily as a result 
  of a reduced non-controlling interest allocation of Consumer Healthcare 
  profits and a reduced Adjusted tax rate. 
 
 
 Currency impact on nine months 2018 results 
  The results for the nine months to September 2018 are based on average 
  exchange rates, principally GBP1/$1.35, GBP1/EUR1.13 and GBP1/Yen 
  148. Comparative exchange rates are given on page 52. The period-end 
  exchange rates were GBP1/$1.30, GBP1/EUR1.12 and GBP1/Yen 148. 
  In the nine months to September 2018, turnover was flat in AER terms 
  but increased 4% CER. Total EPS was 49.0p compared with EPS of 42.5p 
  in 2017 and Adjusted EPS was 88.3p compared with 84.6p in 2017, up 
  4% AER, 12% CER. The negative currency impact primarily reflected 
  the strength of Sterling, particularly against the US Dollar, Yen 
  and Emerging Market currencies, relative to 2017. Exchange gains 
  or losses on the settlement of intercompany transactions had a negligible 
  impact on the negative currency impact of eight percentage points 
  on Adjusted EPS.

       GSK has revised its definition of free cash flow to include proceeds 
       from disposals of intangible assets, as set out on page 55. Comparative 
       figures have been revised accordingly.

 Q3 2018 
  The net cash inflow from operating activities for the quarter was 
  GBP2,077 million (Q3 2017: GBP1,897 million). The increase primarily 
  reflected improved operating profits, the phasing of tax payments 
  and reduced legal settlement costs, partly offset by a negative currency 
  impact on operating profit, and a larger increase in working capital, 
  primarily seasonal and other receivables, compared with Q3 2017 particularly 
  related to the growth in Vaccines sales. 
  Total cash payments to Shionogi in relation to the ViiV Healthcare 
  contingent consideration liability in the quarter were GBP208 million, 
  of which GBP185 million was recognised in cash flows from operating 
  activities and GBP23 million was recognised in contingent consideration 
  paid within investing cash flows. These payments are deductible for 
  tax purposes. 
  Free cash flow was GBP1,554 million for the quarter (Q3 2017: GBP1,282 
  million). The increase primarily reflected improved operating profits, 
  the phasing of tax payments, reduced legal settlement costs and increased 
  disposals of intangible assets of GBP142 million primarily relating 
  to the disposal of tapinarof (Q3 2017: GBP6 million). This was partly 
  offset by a negative currency impact on operating profit and increased 
  working capital primarily reflecting a larger increase in seasonal 
  and other receivables compared with Q3 2017, particularly related 
  to the growth in Vaccines sales. 
 
 
 9 months 2018 
  The net cash inflow from operating activities for the nine months 
  was GBP4,302 million (2017: GBP4,049 million). The increase primarily 
  reflected improved operating profits, reduced legal settlement costs 
  and restructuring payments and favourable timing of payments for 
  returns and rebates, partly offset by a negative currency impact 
  on operating profit and a larger increase in working capital, primarily 
  seasonal and other receivables compared with 2017, particularly related 
  to the growth in Vaccines sales. 
  Total cash payments to Shionogi in relation to the ViiV Healthcare 
  contingent consideration liability in the nine months were GBP584 
  million, of which GBP517 million was recognised in cash flows from 
  operating activities and GBP67 million was recognised in contingent 
  consideration paid within investing cash flows. These payments are 
  deductible for tax purposes. 
  Free cash flow was GBP2,375 million for the nine months (2017: GBP1,668 
  million). The increase primarily reflected improved operating profits, 
  reduced legal settlement costs and restructuring payments, favourable 
  timing of payments for returns and rebates, lower capital expenditures 
  including a favourable comparison to the impact of the Priority Review 
  Voucher in 2017, increased disposals of intangible assets of GBP165 
  million (2017: GBP24 million), primarily relating to the disposal 
  of tapinarof, as well as reduced dividend payments to non-controlling 
  interests. This was partly offset by a negative currency impact on 
  operating profit, increased contingent consideration payments including 
  the $450 million (GBP317 million) milestone to Novartis paid in Q1 
  2018 and increased working capital reflecting a larger increase in 
  seasonal and other receivables compared with 2017 particularly related 
  to growth in Vaccines sales. 
 
 
 Net debt 
  At 30 September 2018, net debt was GBP23.8 billion, compared with 
  GBP13.2 billion at 31 December 2017, comprising gross debt of GBP27.7 
  billion and cash and liquid investments of GBP3.9 billion. Net debt 
  increased due to the GBP9.3 billion acquisition from Novartis of 
  the remaining stake in the Consumer Healthcare Joint Venture in June 
  2018, the GBP0.2 billion acquisition of the investment in 23andMe, 
  GBP0.6 billion of unfavourable exchange impacts from the translation 
  of non-Sterling denominated debt, and dividends paid to shareholders 
  of GBP3.0 billion, partly offset by increased free cash flow of GBP2.4 
  billion after the milestone payment to Novartis. 
  At 30 September 2018, GSK had short-term borrowings (including overdrafts) 
  repayable within 12 months of GBP2.9 billion with loans of GBP6.6 
  billion repayable in the subsequent year.

 The increase of 7 days in Q3 2018 was predominantly due to an increase 
  in receivables reflecting increased seasonal and other sales in Q3, 
  particularly related to the growth in Vaccines sales partly offset 
  by reduced inventory levels. 
  The increase of 20 days compared with September 2017 primarily reflected 
  the increase in trade receivables as a result of recent sales growth, 
  particularly new launches, and the full year impact of inventory 
  for new product launches. It was also affected by reduced denominator 
  due to lower restructuring and impairment costs in 2018 and an increase 
  due to exchange rates (compared with a reduction impacting September 
  2017). 
 
 
 Returns to shareholders 
 
 
 Quarterly dividends 
  The Board has declared a third interim dividend for 2018 of 19 pence 
  per share (Q3 2017: 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 intends to maintain the dividend for 2018 at the current 
  level of 80p per share, subject to any material change in the external 
  environment or performance expectations. Over time, as free cash 
  flow strengthens, it intends to build free cash flow cover of the 
  annual dividend to a target range of 1.25-1.50x, before returning 
  the dividend to growth. 
  Payment of dividends 
  The equivalent interim dividend receivable by ADR holders will be 
  calculated based on the exchange rate on 8 January 2019. An annual 
  fee of $0.02 per ADS (or $0.005 per ADS per quarter) is charged by 
  the Depositary. 
  The ex-dividend date will be 15 November 2018, with a record date 
  of 16 November 2018 and a payment date of 10 January 2019.

 GSK made no share repurchases during the quarter. The company issued 
  0.6 million shares under employee share schemes for proceeds of GBP8 
  million (Q3 2017: GBP3 million). 
  The weighted average number of shares for Q3 2018 was 4,917 million, 
  compared with 4,890 million in Q3 2017. 
 
 
 Research and development 
 
 
 GSK remains focused on delivering an improved return on its investment 
  in R&D. Sales contribution, reduced attrition, cost reduction and 
  time to market are all important drivers of improving our internal 
  rate of return. R&D expenditure is not determined as a percentage 
  of sales but instead capital is allocated using strict returns based 
  criteria depending on the pipeline opportunities available. 
 
  The R&D operations in Pharmaceuticals are broadly split into Discovery 
  activities and Development work, each supported by specific and common 
  infrastructure and other shared services where appropriate. The new 
  R&D strategy has redefined the allocation of costs between Discovery 
  and Development such that Discovery now includes all activities up 
  to and including phase I. Development includes phase II activities 
  onwards (previously phase IIa activities were included within Discovery). 
  In addition, the methodology of allocating projects by phase has 
  been revised. Comparative information has been revised accordingly. 
  The impact on Q3 2017 was to increase Discovery costs by GBP24 million 
  and Technology, facilities and functional support costs by GBP13 
  million and reduce Development costs by GBP37 million. The impact 
  on the nine months to September 2017 was to increase Discovery costs 
  by GBP31 million and Technology, facilities and functional support 
  costs by GBP27 million and reduce Development costs by GBP58 million.

 In Q3 2018, Adjusted R&D expenditure increased 7% AER, 8% CER, with 
  Pharmaceuticals up 6% AER, 8% CER primarily reflecting an increased 
  investment in the progression of a number of mid and late stage programmes, 
  particularly in Oncology, as well as the provision for costs expected 
  to be payable to a third party relating to the future use of a Priority 
  Review Voucher. The decline in Discovery primarily reflected the 
  phasing of expenditure on specific programmes, including the transfer 
  of certain Oncology assets into the development phase as well as 
  the benefits of the re-prioritisation of R&D that started in the 
  second half of 2017. The growth in Technology, facilities and functional 
  support costs primarily reflected increased investments in data analytics. 
 
 
 In the nine months to 30 September 2018, Adjusted R&D expenditure 
  declined 5% AER, 3% CER with Pharmaceuticals down 9% AER, 6% CER, 
  primarily reflecting the comparison with the impact of the utilisation 
  of the Priority Review Voucher in 2017 and the benefit of the prioritisation 
  initiatives started in Q3 2017. This was partly offset by increased 
  investment in the progression of a number of mid and late stage programmes, 
  particularly in Oncology, and the provision for costs expected to 
  be payable to a third party relating to the future use of a Priority 
  Review Voucher. 
 
 
 R&D pipeline 
 
 
 Pipeline news flow since Q2 2018: 
 
 
 Respiratory 
 GSK has led the way in developing innovative medicines to advance 
  the management of asthma and COPD for nearly 50 years. Over the last 
  five years we have launched six innovative medicines responding to 
  continued unmet patient need, despite existing therapies. 
 
 
 Trelegy Ellipta 
 --   On 21 September, the European Medicines Agency's Committee for 
       Medicinal Products for Human Use issued a positive opinion supporting 
       the use of Trelegy Ellipta (FF/UMEC/VI) in patients not adequately 
       treated by a long-acting muscarinic receptor antagonist and long-acting 
       <BETA>2-agonist. It also referenced the effect on exacerbations 
       based on data from the InforMing the PAthway of COPD Treatment 
       (IMPACT) study. 
 
 
 Anoro and Incruse Ellipta 
 --   In July, regulatory submissions were made to the US FDA to support 
       potential updates to the relevant sections of the labelling for 
       both Anoro Ellipta (UMEC/VI) and Incruse Ellipta (UMEC). These 
       were primarily based on data from the landmark IMPACT trial which 
       showed the contribution of umeclidinium on reduction in exacerbations 
       (FF/UMEC/VI compared with FF/VI). Similar submissions to regulators 
       in the EU were made in October 2018. 
 
 
 Nucala severe asthma 
 --   On 30 August, the European Commission approved Nucala (mepolizumab) 
       as an add-on treatment for severe refractory eosinophilic asthma 
       in paediatric patients aged six up to 17 years. As a result of 
       this licence extension, Nucala is now approved for use for severe 
       refractory eosinophilic asthma in both adult and paediatric patients 
       in the 31 European countries covered by the EMA. 
 
 
 --   On 10 September, results from an indirect treatment comparison 
       of the licensed doses of Nucala (mepolizumab), versus benralizumab 
       and reslizumab in patients with severe eosinophilic asthma were 
       published in The Journal of Allergy and Clinical Immunology. The 
       data showed that in patients with similar blood eosinophil counts, 
       mepolizumab significantly reduced clinically significant exacerbations 
       and improved asthma control compared with both benralizumab and 
       reslizumab. 
 
 
 --   In the third quarter, a regulatory filing was submitted in both 
       EU and US for a liquid formulation of Nucala (mepolizumab) to be 
       administered subcutaneously via an autoinjector or a safety syringe 
       device. Updates regarding regulatory actions in 2019 will be provided 
       in due course. 
 
 
 Nucala COPD 
 --   On 7 September, the US FDA issued a complete response letter (CRL) 
       for the use of Nucala (mepolizumab) as an add-on treatment to inhaled 
       corticosteroid-based maintenance treatment for the reduction of 
       exacerbations in patients with COPD, guided by blood eosinophil 
       counts. The CRL stated that more clinical data are required to 
       support an approval. 
 
 
 Danirixin (GSK1325756) 
 --   In October, a planned interim analysis of the phase IIb dose-ranging 
       study of danirixin in patients with COPD was undertaken. This interim 
       analysis showed danirixin did not achieve the primary efficacy 
       endpoint and this has changed the understanding of the risk/benefit 
       profile of this asset in COPD. Based on these data GSK has taken 
       the decision to stop development in COPD. 
 
 
 TRPV4 (GSK2798745) 
 --   In September, data from a planned interim analysis of the ongoing 
       clinical phase II study of the TRPV4 blocker GSK'745 in patients 
       with chronic cough showed it had met the pre-defined criteria for 
       futility. Based on these data, GSK has taken the decision to stop 
       ongoing development of GSK'745 for cough due to lack of efficacy. 
       The phase I programme in acute respiratory distress syndrome is 
       continuing. 
 
 
 TLR7 (GSK2245035) 
 --   In September 2018, data from a phase II study of GSK'035 in mild 
       asthmatic patients showed it did not meet its pre-determined success 
       criteria. Based on these data, GSK has taken the decision to stop 
       ongoing development of GSK'035 in asthma due to lack of efficacy. 
 
 
 HIV/Infectious diseases 
 GSK has a long-standing commitment to HIV and infectious diseases 
  - our scientists discovered amoxicillin, the widely used antibiotic, 
  over 40 years ago, and developed the first medicines approved to 
  treat HIV (AZT), HBV (lamivudine), herpes viruses (acyclovir) and 
  influenza (zanamivir). Today, we are investigating new medicines 
  to treat, prevent and possibly, ultimately cure HIV and other infectious 
  diseases. Our scientists are committed to developing medicines that 
  advance HIV care by exploring new treatment paradigms (two-drug regimens), 
  new modalities (long-acting injectables) and new mechanisms of actions 
  (including maturation inhibitors and broadly neutralising antibodies). 
 
 
 Cabotegravir + rilpivirine 
 --   On 30 October, positive 48-week results for FLAIR, the second global 
       phase III study of long-acting, injectable two-drug regimen for 
       the treatment of HIV were announced. 
 
 
 --   On 29 October, three-year results from LATTE-2, a phase IIb study 
       showing high rates of virus suppression from first long-acting 
       injectable, two-drug HIV regimen were presented at HIV Glasgow 
       Drug Therapy meeting in Scotland. 
 
 
 --   On 15 August, positive headline results from the global, phase 
       III ATLAS study of a long-acting, injectable two-drug regimen for 
       the treatment of HIV were announced. 
 
 
 Dolutegravir + lamivudine 
 --   On 18 October, a regulatory application was submitted to the US 
       FDA for a single-tablet, two-drug regimen of dolutegravir and lamivudine 
       for treatment of HIV. 
 
 
 --   On 14 September, a regulatory application was submitted to the 
       European Medicines Agency for a single-tablet, two-drug regimen 
       of dolutegravir and lamivudine for treatment of HIV. 
 
 
 Immuno-inflammation 
 Immuno-inflammatory diseases are relatively common, chronic, debilitating 
  conditions. While diverse in presentation, they are collectively 
  hallmarked by impairment of quality of life and can lead to premature 
  mortality. There is significant unmet need for improved treatment 
  options for immuno-inflammatory diseases. 
 
 
 Benlysta 
 --   On 23 October, data on Benlysta (belimumab) phase II study (PLUTO) 
       in paediatric patients with childhood-onset systemic lupus erythematosus 
       were presented at American College of Rheumatology (ACR). 
 
 
 --   In September, data from the Benlysta (belimumab) phase IV study 
       (EMBRACE) in adult patients of black race with active, autoantibody-positive, 
       systemic lupus erythematosus who received standard therapy were 
       received in-house. Data to be presented at a future scientific 
       congress. 
 
 
 Anti-GM-CSF antibody (GSK3196165) 
 --   On 22 October, data from the phase II study (BAROQUE) of anti-GM-CSF 
       antibody (GSK'165) were presented at ACR supporting its efficacy 
       and safety in patients with rheumatoid arthritis. The patient benefit 
       supports further clinical development for RA. 
 
 
 --   On 22 October, data from the phase IIa study of anti-GM-CSF antibody 
       (GSK'165) in patients with inflammatory hand osteoarthritis were 
       presented at ACR. As a result of these data, development of the 
       asset for potential use in treatment of hand osteoarthritis was 
       terminated during the second quarter. 
 
 
 Oncology 
 Cancer is one of the leading causes of death in the developed world. 
  GSK is focused on delivering transformational therapies for cancer 
  patients that may help to maximise their survival. GSK's pipeline 
  is focused on immuno-oncology, cell therapy, and epigenetics. Our 
  goal is to achieve a sustainable flow of new treatments for cancer 
  patients based on a diversified portfolio of investigational medicines 
  utilising modalities such as small molecules, antibodies, multi-specific 
  molecules, adjuvants and cells, either alone or in combination. 
 
 
 ICOS agonist (GSK3359609) 
 --   On 22 October, phase I safety, pharmacokinetic and pharmacodynamic 
       data for GSK'609 (monotherapy and combination with pembrolizumab) 
       were presented at the European Society for Medical Oncology meeting. 
 
 
 BCMA antibody-drug conjugate (GSK2857916) 
 --   On 12 October, the phase II study of GSK'916 in combination with 
       standard of care in 2nd line multiple myeloma was started; primary 
       results are anticipated in 2020. Interim data from this study will 
       be used to inform the start of two phase III studies in 2nd line 
       multiple myeloma in 2019. 
 
 
 Other pharmaceuticals 
 
 
 Kozenis (tafenoquine) 
 --   On 12 September, Kozenis (tafenoquine) was approved by the Australian 
       Therapeutic Goods Administration for the radical cure of P. vivax 
       malaria. 
 
 
 Daprodustat (GSK1278863) 
 --   In October, positive results from the open-label, phase III study 
       in 28 Japanese patients with anaemia associated with chronic kidney 
       disease were presented at Kidney Week/the American Society for 
       Nephrology annual meeting. 
 
 
 --   On 29 October, positive phase III data were announced from the 
       second of three pivotal studies of daprodustat in 271 Japanese 
       patients on dialysis with anaemia associated with chronic kidney 
       disease. 
 
 
 Miridesap (GSK2315698) and dezamizumab (GSK2398852) 
 --   On 16 October, further development of miridesap and dezamizumab 
       (SAP antagonist) for systemic amyloidosis was terminated due to 
       data that has changed the risk/benefit profile of the dual therapy. 
 
 
 Vaccines 
 Our Vaccines business is one of the largest in the world with the 
  broadest portfolio of any company. The focus of GSK Vaccines pipeline 
  is to maintain GSK's meningococcal meningitis market leadership with 
  both licensed and candidate vaccines. In addition, we are pursuing 
  a full RSV portfolio for infants, older adults and maternal immunisation, 
  with different approaches tailored to the specific segments. This 
  portfolio has the potential to deliver a series of first and/or best 
  in class vaccines. In addition, we continue to leverage our unique 
  technology platforms to target new, emerging or remaining medical 
  needs. 
 
 
 Tuberculosis vaccine 
 --   On 25 September 2018, GSK and Aeras announced that GSK's M72/AS01 
       candidate vaccine significantly reduced the incidence of pulmonary 
       tuberculosis disease in HIV-negative adults with latent tuberculosis 
       infection in an ongoing phase IIb clinical trial testing. These 
       primary results were published in the New England Journal of Medicine. 
 
 
 Reporting definitions 
 
 
 GSK uses a number of adjusted, non-IFRS, measures to report the performance 
  of its business. These measures are used by management for planning 
  and reporting purposes and in discussions with and presentations 
  to investment analysts and rating agencies and may not be directly 
  comparable with similarly described measures used by other companies. 
  Non-IFRS measures may be considered in addition to, but not as a 
  substitute for or superior to, information presented in accordance 
  with IFRS. 
 
  Total results 
  Total reported results represent the Group's overall performance. 
  However, these results can contain material unusual or non-operational 
  items that may obscure the key trends and factors determining the 
  Group's operational performance. As a result, GSK also reports Adjusted 
  results, which is a non-IFRS measure. 
 
  Adjusted results 
  GSK believes that Adjusted results allow the key trends and factors 
  driving the Group's performance to be more easily and clearly identified 
  by shareholders. The definition of Adjusted results, as set out below, 
  also aligns the Group's results with the majority of its peer companies 
  and how they report earnings. 
 
  Adjusted results exclude the following items from Total results: 
  amortisation and impairment of intangible assets (excluding computer 
  software) and goodwill; major restructuring costs (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 those integration costs following material acquisitions; 
  significant legal charges (net of insurance recoveries) and expenses 
  on the settlement of litigation and government investigations, transaction-related 
  accounting adjustments for significant acquisitions, and other items, 
  including disposals of associates, products and businesses and other 
  operating income other than royalty income, together with the tax 
  effects of all of these items and the impact of the enactment of 
  the US Tax Cuts and Jobs Act in 2017. Costs for all other ordinary 
  course smaller scale restructuring and legal charges and expenses 
  are retained within Total and Adjusted results. 
 
  As Adjusted results may exclude significant costs, such as those 
  from major restructuring programmes or significant legal charges, 
  they should not be regarded as a complete picture of the Group's 
  financial performance which is presented in its Total results. 
 
  Reconciliations between Total and Adjusted results, as set out on 
  pages 16, 24 and 58 to 61, including detailed breakdowns of the key 
  adjusting items, are provided to shareholders to ensure full visibility 
  and transparency as they assess the Group's performance. 
 
  Free cash flow 
  With the introduction of the new R&D strategy in Q2 2018, GSK has 
  revised its definition of free cash flow, a non-IFRS measure, to 
  include proceeds from the sale of intangible assets. This balances 
  with the expenditure on purchases of intangible assets, which is 
  deducted in calculating free cash flow, and makes the treatment of 
  intangible assets consistent with property, plant and equipment. 
  Free cash flow is now defined as the net cash inflow from operating 
  activities less capital expenditure on property, plant and equipment 
  and intangible assets, contingent consideration payments, net interest, 
  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 55. 
 
  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. 
 
  Working capital conversion cycle 
  The working capital conversion cycle is calculated as the number 
  of days sales outstanding plus days inventory outstanding, less days 
  purchases outstanding. 
 
  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. 
 
 
 Outlook, assumptions and cautionary statements 
 
 In May 2015, GSK announced that it expected Group sales to grow at 
  CER at a low-to-mid single digits percentage CAGR and Adjusted EPS 
  to grow at CER at a mid-to-high single digits percentage CAGR for 
  the period 2016-2020. These outlooks are based on 2015 exchange rates. 
 
  Assumptions related to 2018 guidance and 2016-2020 outlook 
  In outlining the expectations for 2018 and the five-year period 2016-2020, 
  the Group has made certain assumptions about the healthcare sector, 
  the different markets in which the Group operates and the delivery 
  of revenues and financial benefits from its current portfolio, pipeline 
  and restructuring programmes. 
 
  For the Group specifically, over the period to 2020 GSK expects further 
  declines in sales of Seretide/Advair. The introduction of a generic 
  alternative to Advair in the US has been factored into the Group's 
  assessment of its future performance. The Group assumes no premature 
  loss of exclusivity for other key products over the period. 
 
  The assumptions for the Group's revenue and earnings expectations 
  assume no material interruptions to supply of the Group's products 
  and no material mergers, acquisitions, disposals, litigation costs 
  or share repurchases for the Company; and no change in the Group's 
  shareholdings in ViiV Healthcare. The assumptions also assume no 
  material changes in the macro-economic and healthcare environment. 
  The 2018 guidance and 2016-2020 outlook have factored in all divestments 
  and product exits since 2015, including the divestment and exit of 
  more than 130 non-core tail brands (GBP0.5 billion in annual sales) 
  as announced on 26 July 2017. 
 
  The Group's expectations assume successful delivery of the Group's 
  integration and restructuring plans over the period 2016-2020 including 
  the extension and enhancement to the combined programme announced 
  on 26 July 2017 as well as the new major restructuring plan announced 
  on 25 July 2018. Material costs for investment in new product launches 
  and R&D have been factored into the expectations given. Given the 
  potential development options in the Group's pipeline, the outlook 
  may be affected by additional data-driven R&D investment decisions. 
  The expectations are given on a constant currency basis (2016-2020 
  outlook at 2015 CER). Subject to material changes in the product 
  mix, and following the enactment of US tax reform, the Group's medium-term 
  effective tax rate is expected to be in the region of 19-20% of Adjusted 
  profits. This incorporates management's best estimates of the impact 
  of US tax reform on the Group based on the information currently 
  available. As more information on the detailed application of the 
  US Tax Cuts and Jobs Act becomes available, the assumptions underlying 
  these estimates could change with consequent adjustments to the charges 
  taken that could have a material impact on the results of the Group. 
 
  Assumptions and cautionary statement regarding forward-looking statements 
  The Group's management believes that the assumptions outlined above 
  are reasonable, and that the aspirational targets described in this 
  report are achievable based on those assumptions. However, given 
  the longer term nature of these expectations and targets, they are 
  subject to greater uncertainty, including potential material impacts 
  if the above assumptions are not realised, and other material impacts 
  related to foreign exchange fluctuations, macroeconomic activity, 
  changes in regulation, government actions or intellectual property 
  protection, actions by our competitors, and other risks inherent 
  to the industries in which we operate. 
 
  This document contains statements that are, or may be deemed to be, 
  "forward-looking statements". Forward-looking statements give the 
  Group's current expectations or forecasts of future events. An investor 
  can identify these statements by the fact that they do not relate 
  strictly to historical or current facts. They use words such as 'anticipate', 
  'estimate', 'expect', 'intend', 'will', 'project', 'plan', 'believe', 
  'target' and other words and terms of similar meaning in connection 
  with any discussion of future operating or financial performance. 
  In particular, these include statements relating to future actions, 
  prospective products or product approvals, future performance or 
  results of current and anticipated products, sales efforts, expenses, 
  the outcome of contingencies such as legal proceedings, 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 2017. 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.

 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 President, 
  Pharmaceuticals R&D and is reported as a separate 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.

 Legal matters 
  The Group is involved in significant legal and administrative proceedings, 
  principally product liability, intellectual property, tax, anti-trust 
  and governmental investigations as well as related private litigation, 
  which are more fully described in the 'Legal Proceedings' note in 
  the Annual Report 2017. 
  At 30 September 2018, the Group's aggregate provision for legal and 
  other disputes (not including tax matters described under 'Taxation' 
  below) was GBP0.2 billion (31 December 2017: GBP0.2 billion). The 
  Group may become involved in significant legal proceedings in respect 
  of which it is not possible to make a reliable estimate of the expected 
  financial effect, if any, that could result from ultimate resolution 
  of the proceedings. In these cases, the Group would provide appropriate 
  disclosures about such cases, but no provision would be made. 
  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. 
  There have been no significant legal development since the date of 
  the Annual Report 2017 and the Q2 2018 results. 
  Developments with respect to tax matters are described in 'Taxation' 
  below. 
 
 
 Taxation 
  Issues related to taxation are described in the 'Taxation' note in 
  the Annual Report 2017. 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. 
  In the quarter, tax on Adjusted profits amounted to GBP430 million 
  and represented an effective Adjusted tax rate of 18.6% (Q3 2017: 
  21.0%). The tax on Total profits amounted to GBP193 million and represented 
  an effective tax rate of 11.3% (Q3 2017: 18.5%). 
  In the nine months, tax on Adjusted profits amounted to GBP1,180 
  million and represented an effective Adjusted tax rate of 19.5% (2017: 
  21.4%). The charge for taxation on Total profits amounted to GBP680 
  million and represented an effective tax rate of 19.8% (2017: 17.9%). 
  The Group's balance sheet at 30 September 2018 included a current 
  tax payable liability of GBP813 million, a non-current tax payable 
  liability of GBP272 million and a tax recoverable asset of GBP257 
  million.

 This unaudited Results Announcement contains condensed financial 
  information for the three and nine months ended 30 September 2018, 
  and should be read in conjunction with the Annual Report 2017, which 
  was prepared in accordance with International Financial Reporting 
  Standards as adopted by the European Union. This Results Announcement 
  has been prepared applying consistent accounting policies to those 
  applied by the Group in the Annual Report 2017, except for the implementation 
  of IFRS 15 'Revenue from contracts with customers' and IFRS 9 'Financial 
  instruments' from 1 January 2018. These new Standards have not had 
  a material impact on the reported results of the Group. 
  GSK has adopted IFRS 15 applying the modified retrospective approach, 
  with a cumulative adjustment to decrease equity at 1 January 2018 
  by GBP4 million. In accordance with the requirements of the standard, 
  where the modified retrospective approach is adopted, prior year 
  results are not restated. IFRS 15 provides a single, principles-based 
  approach to the recognition of revenue from all contracts with customers. 
  It focuses on the identification of performance obligations in a 
  contract and requires revenue to be recognised when or as those performance 
  obligations are satisfied. 
  GSK has adopted IFRS 9 retrospectively, but with certain permitted 
  exceptions. As a result, prior year results are also not restated, 
  but a cumulative adjustment has been made to decrease equity at 1 
  January 2018 by GBP11 million, primarily reflecting an increase in 
  the expected credit loss provision on trade receivables of GBP15 
  million. A net transfer of GBP288 million between retained earnings 
  and other reserves has also been made. This primarily reflects prior 
  impairments of equity investments that had previously been charged 
  to the income statement. IFRS 9 replaces the majority of IAS 39 and 
  covers the classification, measurement and de-recognition of financial 
  assets and financial liabilities, introduces a new impairment model 
  for financial assets based on expected losses rather than incurred 
  losses and provides a new hedge accounting model. 
  IFRS 16 'Leases' is required to be implemented by the Group from 
  1 January 2019. The new standard will replace IAS 17 'Leases' and 
  will require lease liabilities and "right of use" assets to be recognised 
  on the balance sheet for almost all leases. This is expected to result 
  in a significant increase in both assets and liabilities recognised 
  on the balance sheet. The costs of operating leases currently included 
  within operating costs will be split and the financing element of 
  the charge will be reported within finance expense. The Group is 
  assessing the potential impact of the new standard. 
  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 2017 were published 
  in the Annual Report 2017, which has been delivered to the Registrar 
  of Companies and on which the report of the independent auditors 
  was unqualified and did not contain a statement under section 498 
  of the Companies Act 2006. 
 
 
 Exchange rates 
 GSK operates in many countries, and earns revenues and incurs costs 
  in many currencies. The results of the Group, as reported in Sterling, 
  are affected by movements in exchange rates between Sterling and 
  other currencies. Average exchange rates, as modified by specific 
  transaction rates for large transactions, prevailing during the period, 
  are used to translate the results and cash flows of overseas subsidiaries, 
  associates and joint ventures into Sterling. Period-end rates are 
  used to translate the net assets of those entities. The currencies 
  which most influenced these translations and the relevant exchange 
  rates were:

 During Q3 2018, average Sterling exchange rates were stronger against 
  the US Dollar, but weaker against the Euro and Yen compared with 
  the same period in 2017. During the nine months ended 30 September 
  2018, average Sterling exchange rates were stronger against the US 
  Dollar and the Yen, but weaker against the Euro, compared with the 
  same period in 2017. Period-end Sterling exchange rates were weaker 
  against the US Dollar, the Euro and Yen compared with the 2017 year 
  end rates.

 At 30 September 2018, 4,919 million shares were in free issue (excluding 
  Treasury shares and shares held by the ESOP Trusts). This compares 
  with 4,890 million shares at 30 September 2017. 
 
 
 Net assets 
 The book value of net assets increased by GBP234 million from GBP3,489 
  million at 31 December 2017 to GBP3,723 million at 30 September 2018. 
  This primarily reflected the Total profit for the period and re-measurement 
  gains on defined benefit plans exceeding dividends paid in the period. 
  The carrying value of investments in associates and joint ventures 
  at 30 September 2018 was GBP221 million (31 December 2017: GBP183 
  million), with a market value of GBP411 million (31 December 2017: 
  GBP372 million). 
  At 30 September 2018, the net deficit on the Group's pension plans 
  was GBP488 million compared with GBP1,505 million at 31 December 
  2017. The decrease in the net deficit primarily arose from increases 
  in the rates used to discount UK pension liabilities from 2.5% to 
  2.9%, and US pension liabilities from 3.6% to 4.2%. 
  At 30 September 2018, the post-retirement benefits provision was 
  GBP1,387 million compared with GBP1,496 million at 31 December 2017. 
  The decrease in the provision was primarily due to the increase in 
  the US discount rate from 3.6% to 4.2%. 
  At 30 September 2018, trade and other payables were GBP13,093 million 
  compared with GBP20,970 million at 31 December 2017. The decrease 
  primarily reflected the elimination of the Consumer Healthcare Joint 
  Venture put option following the buyout of Novartis' interest in 
  the Consumer Healthcare Joint Venture on 1 June 2018. The buyout 
  was funded by issuing bonds with maturity rates of between two and 
  twelve years, in both the US and Europe, which raised $6 billion 
  and EUR2.5 billion respectively. Committed bank facilities financed 
  the remaining amount of the $13 billion transaction. 
  The estimated present value of the potential redemption amount of 
  the Pfizer put option related to ViiV Healthcare, recorded in Other 
  payables in Current liabilities, was GBP1,278 million (31 December 
  2017: GBP1,304 million). 
  Contingent consideration amounted to GBP6,232 million at 30 September 
  2018 (31 December 2017: GBP6,172 million), of which GBP5,885 million 
  (31 December 2017: GBP5,542 million) represented the estimated present 
  value of amounts payable to Shionogi relating to ViiV Healthcare 
  and GBP296 million (31 December 2017: GBP584 million) represented 
  the estimated present value of contingent consideration payable to 
  Novartis related to the Vaccines acquisition following a milestone 
  payment of $450 million made to Novartis in January 2018. 
  The liability due to Shionogi included GBP242 million in respect 
  of preferential dividends. The liability for preferential dividends 
  due to Pfizer at 30 September 2018 was GBP17 million (31 December 
  2017: GBP17 million). An explanation of the accounting for the non-controlling 
  interests in ViiV Healthcare is set out on page 56. 
  Of the contingent consideration payable (on a post-tax basis) at 
  30 September 2018, GBP818 million (31 December 2017: GBP1,076 million) 
  is expected to be paid within one year. The consideration payable 
  for the acquisition of the Shionogi-ViiV Healthcare joint venture 
  and the Novartis Vaccines business is expected to be paid over a 
  number of years. As a result, the total estimated liabilities are 
  discounted to their present values, on a post-tax basis using post-tax 
  discount rates. The Shionogi-ViiV Healthcare contingent consideration 
  liability is discounted at 8.5% and the Novartis Vaccines contingent 
  consideration liability is discounted partly at 8% and partly at 
  9%. 
 
 
 The liabilities for the Pfizer put option and the contingent consideration 
  at 30 September 2018 have been calculated based on the closing exchange 
  rates, primarily US$1.30/GBP1 and Euro EUR1.12/GBP1. The sensitivities 
  for each of the largest contingent consideration liabilities and 
  the Pfizer put option are set out below.

 The re-measurements of contingent consideration in the nine months 
  reflected updated forecasts, exchange rate movements and the unwind 
  of the discounts on the liabilities. The cash settlement in the period 
  included GBP584 million (2017: GBP485 million) of payments to Shionogi 
  in relation to ViiV Healthcare and the GBP317 million milestone payment 
  to Novartis relating to the non-US sales of Bexsero. These payments 
  are deductible for tax purposes. 
 
 
 At 30 September 2018, the ESOP Trust held 41.9 million GSK shares 
  against the future exercise of share options and share awards. The 
  carrying value of GBP214 million has been deducted from other reserves. 
  The market value of these shares was GBP650 million. 
 
  At 30 September 2018, the company held 414.6 million Treasury shares 
  at a cost of GBP5,800 million, which has been deducted from retained 
  earnings. 
 
 
 Contingent liabilities 
 There were contingent liabilities at 30 September 2018 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 and tax disputes to which the Group is a party are set out 
  on page 51.

 With the introduction of the new R&D strategy in Q2 2018, GSK has 
  revised its definition of free cash flow, a non-IFRS measure, to 
  include proceeds from the sale of intangible assets. 
 
 
 Non-controlling interests in ViiV Healthcare 
 
 
 Trading profit allocations 
  Because ViiV Healthcare is a subsidiary of the Group, 100% of its 
  operating results (turnover, operating profit, profit after tax) 
  are included within the Group income statement and then a portion 
  of the earnings is allocated to the non-controlling interests owned 
  by the other shareholders, in line with their respective equity shareholdings 
  (Pfizer 11.7% and Shionogi 10%). Each of the shareholders, including 
  GSK, is also entitled to preferential dividends 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 of ViiV Healthcare allocated 
  to each shareholder will change. In particular, the increasing sales 
  of Tivicay and Triumeq have a favourable impact on the proportion 
  of the preferential dividends that is allocated to GSK. GSK was entitled 
  to approximately 80% of the Adjusted earnings of ViiV Healthcare 
  for 2017. Re-measurements of the liabilities for the preferential 
  dividends allocated to Pfizer and Shionogi are included within other 
  operating income. 
  Acquisition-related arrangements 
  As part of the agreement reached to acquire Shionogi's interest in 
  the former Shionogi-ViiV Healthcare joint venture in 2012, ViiV Healthcare 
  agreed to pay additional consideration to Shionogi contingent on 
  the performance of the products being developed by that joint venture, 
  principally dolutegravir. The liability for this contingent consideration 
  was estimated and recognised in the balance sheet at the date of 
  acquisition. Subsequent re-measurements are reflected within other 
  operating income/expense and within Adjusting items in the income 
  statement. 
  Cash payments are made to Shionogi by ViiV Healthcare each quarter 
  which reduce the balance sheet liability and are hence not recorded 
  in the income statement. The payments are calculated based on the 
  sales performance of the relevant products in the previous quarter 
  and are reflected in the cash flow statement partly in operating 
  cash flows and partly within investing activities. The tax relief 
  on these payments is reflected in the Group's Adjusting items as 
  part of the tax charge. The part of each payment relating to the 
  original estimate of the fair value of the contingent consideration 
  on the acquisition of the Shionogi-ViiV Healthcare joint venture 
  in 2012 of GBP659 million is reported within investing activities 
  in the cash flow statement and the part of each payment relating 
  to the increase in the liability since the acquisition is reported 
  within operating cash flows. 
 
 
 Movements in contingent consideration payable to Shionogi are as 
  follows: 
 
 
                                                  9 months   9 months

                                                 ---------  --------- 
 
 
 
 Of the contingent consideration payable (on a post-tax basis) to 
  Shionogi at 30 September 2018, GBP794 million (31 December 2017: 
  GBP724 million) is expected to be paid within one year. 
 
 
 Exit rights 
  Pfizer may request an IPO of ViiV Healthcare at any time and if either 
  GSK does not consent to such IPO or an offering is not completed 
  within nine months, Pfizer could require GSK to acquire its shareholding. 
  Under the original agreements, GSK had the unconditional right, so 
  long as it made no subsequent distribution to its shareholders, to 
  withhold its consent to the exercise of the Pfizer put option and, 
  as a result, in accordance with IFRS, GSK did not recognise a liability 
  for the put option on its balance sheet. However, during Q1 2016, 
  GSK notified Pfizer that it had irrevocably given up this right and 
  accordingly recognised the liability for the put option on the Group's 
  balance sheet during Q1 2016 at an initial value of GBP1,070 million. 
  Consistent with this revised treatment, at the end of Q1 2016 GSK 
  also recognised liabilities for the future preferential dividends 
  anticipated to become payable to Pfizer and Shionogi on the Group's 
  balance sheet. 
 
 
 The closing balances of the liabilities related to Pfizer's shareholding 
  are as follows: 
 
 
                                 30 September   31 December 
                                         2018          2017

 Under the original agreements, Shionogi could also have requested 
  GSK to acquire its shareholding in ViiV Healthcare in six month windows 
  commencing in 2017, 2020 and 2022. GSK had the unconditional right, 
  so long as it made no subsequent distribution to its shareholders, 
  to withhold its consent to the exercise of the Shionogi put option 
  and, as a result, GSK did not recognise a liability for the put option 
  on its balance sheet. However, during Q1 2016, GSK notified Shionogi 
  that it had irrevocably given up this right and accordingly recognised 
  the liability for the put option on the Group's balance sheet during 
  Q1 2016 at an initial value of GBP926 million. In Q4 2016, Shionogi 
  irrevocably agreed to waive its put option and as a result GSK de-recognised 
  the liability for this put option on the Group's balance sheet directly 
  to equity. The value of the liability was GBP1,244 million when it 
  was de-recognised. 
  GSK also has a call option over Shionogi's shareholding in ViiV Healthcare, 
  which under the original agreements was exercisable in six month 
  windows commencing in 2027, 2030 and 2032. GSK has now irrevocably 
  agreed to waive the first two exercise windows, but the last six 
  month window in 2032 remains. As this call option is at fair value, 
  it has no value for accounting purposes.

 Adjusted results exclude the above items from Total results as GSK 
  believes that Adjusted results are more representative of the performance

 Adjusted results exclude the above items from Total results as GSK 
  believes that Adjusted results are more representative of the performance 
  of the Group's operations and allow the key trends and factors driving 
  performance to be more easily and clearly identified by shareholders.

 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 for 
  the three and nine months ended 30 September 2018. 
 
 
 What we have reviewed 
 The condensed financial information comprises: 
 --    the income statement and statement of comprehensive income for 
        the three and nine month periods ended 30 September 2018 on pages 
        40 and 41 to 42 respectively; 
 --    the balance sheet as at 30 September 2018 on page 46; 
 --    the statement of changes in equity for the nine month period then 
        ended on page 47; 
 --    the cash flow statement for the nine month period then ended on 
        page 48 and; 
 --    the accounting policies and basis of preparation and the explanatory 
        notes to the condensed financial information on pages 49 to 57 
        that have been prepared applying consistent accounting policies 
        to those applied by the Group in the Annual Report 2017, which 
        was prepared in accordance with International Financial Reporting 
        Standards ("IFRS") as adopted by the European Union, except for 
        the implementation of IFRS 15 "Revenue from Contracts with Customers" 
        and IFRS 9 "Financial Instruments" from 1 January 2018. 
 
 We have read the other information contained in the Results Announcement, 
  including the non-IFRS measures contained on pages 49 to 57, and 
  considered whether it contains any apparent misstatements or material 
  inconsistencies with the information in the condensed 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 Auditing Practices Board. 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 GlaxoSmithKline plc, including the condensed 
  financial information, is the responsibility of, and has been approved 
  by, the directors. The directors are responsible for preparing the 
  Results Announcement by applying consistent accounting policies to 
  those applied by the Group in the Annual Report 2017, which was prepared 
  in accordance with IFRS as adopted by the European Union, except 
  for the implementation of IFRS 15 "Revenue from Contracts with Customers" 
  and IFRS 9 "Financial Instruments" from 1 January 2018. 
 
  Our responsibility 
  Our responsibility is to express to the Company a conclusion on the 
  interim financial information 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 Auditing Practices Board 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 interim financial information in 
  the Results Announcement for the three and nine months ended 30 September 
  2018 are not prepared, in all material respects, in accordance with 
  the accounting policies set out in the accounting policies and basis 
  of preparation section on page 52.
