 Sir Andrew Witty, Chief Executive Officer, GSK said: 
 
 "This is our first full quarter of performance since completion of 
  the transaction with Novartis and it is encouraging. Our integration 
  and restructuring plans are on track and we remain confident that 
  we can achieve our targets for this year and return the Group to earnings 
  growth in 2016. 
 
  "Sales grew 7% on a reported basis and 2% pro-forma. New product performance 
  was positive in all three of GSK's businesses, with the standout performance 
  for the quarter coming from our new HIV drugs, Tivicay and Triumeq. 
  Both of these are tracking ahead of recent best-in-class launches, 
  and together generated sales of GBP294 million. Elsewhere, we saw 
  continued strong uptake for Flonase OTC, an improving market share 
  for Breo Ellipta following the indication for asthma granted in April, 
  and continued uptake of the newly acquired Meningitis vaccines Bexsero 
  and Menveo. Importantly the growth of our new pharmaceutical products 
  is now more than offsetting sales declines of Seretide/Advair. 
  "We will be showcasing further product innovation at our event for 
  investors in November at which we expect to review new data and prospects 
  for advanced and early-stage development projects in HIV, Oncology, 
  Vaccines, Cardiovascular, Immuno-inflammation and Respiratory diseases." 
 
 
 Information and details regarding today's results, including a video 
  interview with CFO Simon Dingemans is available on: www.gsk.com/investors. 
 
 
 Strategy and outlook 
  GSK has created a Group of three world-leading businesses in Pharmaceuticals, 
  Vaccines and Consumer Healthcare, which aims to deliver sustainable 
  and improving returns to shareholders through development of innovative 
  healthcare options for patients and consumers. 
 
  GSK has a strong portfolio of innovative products across these three 
  businesses, enabling the Group to access the fast growing global demand 
  for healthcare and to balance its exposure to future changes in the 
  industry pricing environment. 
 
  The Group has a presence in more than 150 markets, with revenues split 
  across Pharmaceuticals 59%, Consumer Healthcare 25% and Vaccines 16% 
  on a full-year 2014 historic pro-forma basis. Demand for the Group's 
  products is expected to increase worldwide, particularly in Emerging 
  Markets. 
 
  R&D innovation underpins all three businesses. The Group has a pipeline 
  of 40 NMEs (drugs and vaccines) in Phase II/III clinical development, 
  primarily focused on HIV, Oncology, Vaccines, Cardiovascular, Immuno-inflammation 
  and Respiratory diseases. All three businesses are supported by proprietary 
  technologies and manufacturing capabilities in areas such as devices, 
  adjuvants, bio-electronics and formulations. The Group aims to improve 
  returns from its R&D innovation by striking a balance between pricing 
  and volume generation. 
 
  At its Investor Day on 6 May 2015, GSK outlined a series of expectations 
  for its performance over the five year period 2016-2020. This included 
  an expectation that Group core EPS would grow at a CAGR of mid-to-high 
  single digits on a CER basis. The introduction of a generic alternative 
  to Advair in the US was factored into the Group's assessment of its 
  future performance. The Group also stated its intention to pay an 
  annual ordinary dividend of 80p for each of the next three years (2015-2017).

 Group performance 
 
 
 The Novartis transaction completed on 2 March 2015 and so GSK's reported 
  year to date results include four month's turnover of the former Novartis 
  Vaccines and Consumer Healthcare products and exclude sales of the 
  former GSK Oncology business from 2 March. The Group has restated 
  its segment information for the change in its segments described on 
  page 39. 
  In addition, the Group has presented pro-forma growth rates for turnover, 
  core operating profit and core operating profit by business. Pro-forma 
  growth rates are calculated comparing reported turnover and core operating 
  profit for Q2 2015 with the turnover and core operating profit for 
  Q2 2014 adjusted to include the equivalent three month's sales of 
  the former Novartis Vaccines and Consumer Healthcare products and 
  exclude the sales of the former GSK Oncology business during Q2 2014. 
  Similarly, pro-forma growth rates for the half-year are calculated 
  comparing reported turnover and core operating profit for H1 2015 
  with the turnover and core operating profit for H1 2014 adjusted to 
  include the equivalent four month's sales of the former Novartis Vaccines 
  and Consumer Healthcare products and exclude the sales of the former 
  GSK Oncology products from March to June 2014.

 Turnover - Q2 2015 
 
 
 Group turnover for Q2 2015 increased 7% on a reported basis to GBP5,888 
  million, with Pharmaceuticals down 6%, Vaccines up 11% and Consumer 
  Healthcare up 51%, all three businesses reflecting the impact of the 
  Novartis transaction. On a pro-forma basis, Group turnover increased 
  2%, with Pharmaceuticals up 2%, Vaccines down 5% and Consumer Healthcare 
  up 6%. Sales of New Pharmaceutical and Vaccine products as set out 
  on page 24 were GBP446 million in the quarter. 
 
 
 Pharmaceuticals 
  Pharmaceuticals turnover was GBP3,540 million, down 6% on a reported 
  basis, primarily reflecting the disposal of the Oncology business 
  to Novartis. Adjusting for the impact of the disposal, pro-forma turnover 
  was up 2%. Respiratory sales declined 6%, reflecting further declines 
  in Seretide/Advair in both the US and Europe and the continuing transition 
  of the portfolio to newer products. Sales of Established Products 
  declined 5%, with growth of 3% in International offset by declines 
  in the US and Europe. HIV products grew 59%. 
  US Global Pharmaceuticals turnover of GBP1,084 million declined 16% 
  in the quarter and 7% on a pro-forma basis. The pro-forma decline 
  primarily reflected a 12% fall in Respiratory sales and a 16% fall 
  in Established Products sales. Within Respiratory, Advair sales were 
  down 17% to GBP484 million and Flovent sales declined 15% to GBP100 
  million. Breo Ellipta and Anoro Ellipta sales were GBP19 million and 
  GBP12 million respectively in the quarter. Benlysta sales increased 
  21% to GBP51 million and Relenza sales more than doubled to GBP33 
  million partly reflecting the timing of US CDC orders. Lovaza sales 
  were down 22% to GBP24 million following the introduction of generic 
  competition in April 2014. 
 
  In Europe, Global Pharmaceuticals turnover declined 18% to GBP696 
  million on a reported basis and was down 8% on a pro-forma basis. 
  Respiratory sales declined 8% to GBP369 million as a 16% decline in 
  Seretide was partly offset by Relvar Ellipta sales of GBP19 million 
  in the quarter. Established Products sales were down 13% to GBP121 
  million reflecting increased generic competition combined with some 
  capacity constraints to supply for a number of products. 
 
  International Global Pharmaceuticals sales of GBP1,201 million were 
  down 4% on a reported basis and up 1% on a pro-forma basis. Sales 
  in Emerging Markets of GBP771 million declined 6% reported and 1% 
  pro-forma. Continued growth in Respiratory sales of 4%, including 
  Veramyst, up 27%, was more than offset by a decline in Established 
  Products, down 5%, and Dermatology products, down 10%, both of which 
  were impacted by capacity constraints to supply, as well as increased 
  competition to Seretide. Sales in China were also down 14% pro-forma, 
  reflecting the implementation of new pricing policies as part of the 
  ongoing reshaping of the business and the disposal of a number of 
  peripheral parts of the portfolio. In Japan, Global Pharmaceutical 
  sales were up 13% on a pro-forma basis to GBP283 million, including 
  a 9% increase in Adoair sales which partly benefited from the comparison 
  with a Q2 2014, impacted by significant destocking. With sales of 
  Relvar Ellipta of GBP13 million, total Respiratory sales in Japan 
  were up 17% for the quarter. 
 
  HIV turnover increased 59% to GBP559 million, with the US up 84%, 
  Europe up 46% and International up 26%. The growth in all three regions 
  was driven primarily by strong performances from both Tivicay and 
  Triumeq, with sales of GBP145 million and GBP149 million respectively 
  in the quarter. Epzicom/Kivexa sales increased 1% to GBP185 million, 
  benefiting from use in combination with Tivicay. 
  Vaccines 
  Vaccines turnover of GBP814 million grew 11% on a reported basis, 
  but declined 5% on a pro-forma basis, with strong growth in Europe 
  being offset by declines in the US and International after a strong 
  performance in Q2 2014. 
  In the US, reported growth of 13% primarily reflected the contribution 
  of the recently acquired Meningitis portfolio. The pro-forma decline 
  of 5% resulted primarily from lower sales of Infanrix/Pediarix following 
  the return to the market of a competitor vaccine during 2014. 
  In Europe, sales grew 27% on a reported basis, benefiting from the 
  strong performance of Bexsero which also contributed to pro-forma 
  growth of 12%. Sales of Boostrix, up 31%, were helped by improved 
  supply. 
  In International, sales fell 2% to GBP300 million on a reported basis 
  and 16% on a pro-forma basis. The pro-forma decline primarily reflected 
  the phasing of tenders of Synflorix and a number of other products 
  relative to Q2 2014. 
 
 
 Consumer Healthcare 
  Consumer Healthcare turnover grew 51% on a reported basis and 6% on 
  a pro-forma basis to GBP1,509 million, with strong growth in the US 
  and Europe being offset by a weaker performance in International. 
  US turnover increased 66% to GBP360 million, with 28% pro-forma growth 
  primarily reflecting the continuing benefit of the recent launch of 
  OTC Flonase and comparison with a Q2 2014 impacted by supply constraints. 
  Sales in Europe grew 90% to GBP470 million (up 7% pro-forma), largely 
  driven by strong Oral health sales which were boosted by improved 
  supply relative to Q2 2014 but also market share gains following recent 
  new launches. 
  Reported International sales of GBP679 million grew 27%, but declined 
  2% pro-forma, with growth in Oral health products and continued momentum 
  in India offset by the negative impact of reducing channel inventories 
  in the acquired consumer businesses, most notably in China, Russia 
  and the Middle East. 
  Corporate and other unallocated turnover 
  The Corporate and unallocated turnover of GBP25 million represented 
  sales of several Vaccines and Consumer Healthcare products, which 
  are being held for sale in a number of markets. GSK is required to 
  dispose of these products in specific markets in order to meet the 
  requirements of the anti-trust approvals for the Novartis transaction. 
  Agreements to divest these products have been reached and the transactions 
  are expected to complete in H2 2015. 
 
 
 Turnover - H1 2015 
 
 
 Group turnover for H1 2015 increased 4% on a reported basis to GBP11,510 
  million, with Pharmaceuticals down 7%, Vaccines up 11% and Consumer 
  Healthcare up 37%, all three businesses reflecting the impact of the 
  Novartis transaction. On a pro-forma basis, Group turnover increased 
  1%, with Pharmaceuticals down 2%, Vaccines down 1% and Consumer Healthcare 
  up 7%. Sales of New Pharmaceutical and Vaccine products as set out 
  on page 24 were GBP715 million in the six months. 
  Pharmaceuticals 
  Pharmaceuticals turnover was GBP7,063 million, down 7% on a reported 
  basis, primarily reflecting the disposal of the Oncology business. 
  Adjusting for the impact of the disposal, pro-forma turnover was down 
  2%, reflecting an 8% decline in Respiratory sales and a 13% decline 
  in sales of Established Products, partly offset by growth in HIV sales 
  of 51%. 
  US Global Pharmaceuticals reported turnover of GBP2,103 million declined 
  20% in the six months and 14% on a pro-forma basis. This decline primarily 
  reflected a 16% fall in Respiratory sales and a 31% fall in Established 
  Products sales. Within Respiratory, Advair sales were down 19% to 
  GBP876 million and Flovent sales declined 27% to GBP183 million. Breo 
  Ellipta and Anoro Ellipta sales were GBP33 million and GBP21 million, 
  respectively, in the period. The primary driver of the decline in 
  Established Products was Lovaza, which was down 64% to GBP52 million 
  following the launch of generic competition in April 2014. Relenza 
  sales more than doubled to GBP44 million, partly reflecting the timing 
  of US CDC orders, while Benlysta continued its strong growth with 
  sales of GBP97 million, up 24%. 
 
  In Europe, Global Pharmaceuticals turnover declined 12% to GBP1,511 
  million and was down 5% on a pro-forma basis after adjusting for the 
  impact of the Oncology disposal. Respiratory sales declined 6% to 
  GBP761 million as a 14% decline in Seretide was partly offset by Relvar 
  Ellipta sales of GBP35 million in the period. Established Products 
  sales were down 14% to GBP253 million reflecting increased generic 
  competition and some capacity constraints to supply of a number of 
  products. 
 
  International Pharmaceuticals sales were GBP2,444 million, down 5% 
  on a reported basis and down 2% on a pro-forma basis, driven by a 
  decline of 4% (1% pro-forma) in Emerging Markets to GBP1,551 million 
  and a 3% decline (flat pro-forma) in sales in Japan to GBP618 million. 
  Emerging Markets saw continued growth in Respiratory, up 5%, including 
  Seretide, up 3%, but this was more than offset by declines in Established 
  Products, down 9%, and Dermatology products, both of which were impacted 
  by capacity constraints to supply, as well as increased competition 
  to Seretide. China, down 8% pro-forma, also impacted Emerging Markets 
  performance. In Japan, pro-forma Pharmaceutical sales were flat as 
  a 7% increase in Respiratory sales, primarily driven by Relvar Ellipta, 
  was offset by lower sales of Relenza and Established Products. 
 
  HIV turnover increased 51% to GBP1,005 million, with the US up 76%, 
  Europe up 40% and International up 18%. The growth in all three regions 
  was driven primarily by the strong performances of both Tivicay and 
  Triumeq, with sales of GBP257 million and GBP230 million, respectively 
  in the six months. Epzicom/ Kivexa sales increased 1% to GBP361 million, 
  benefiting from use in combination with Tivicay. 
  Vaccines 
  Vaccines turnover of GBP1,513 million grew 11% on a reported basis, 
  benefiting from the newly acquired products from Novartis, but fell 
  1% on a pro-forma basis as growth in the US and Europe was offset 
  by a decline in International sales. 
  In the US, reported growth of 14% (2% pro-forma) primarily reflected 
  strong growth in the Meningitis portfolio as well as in Hepatitis 
  vaccines, which partly benefited from favourable stocking patterns. 
  This growth was partly offset by lower sales of Infanrix/Pediarix 
  as a result of the return to the market of a competitor vaccine during 
  2014. 
  In Europe, sales grew 15% on a reported basis and 5% pro-forma. This 
  reflected strong performances from Boostrix and Bexsero, partly offset 
  by lower Infanrix/Pediarix sales, which were impacted by the introduction 
  of a competitor vaccine in 2014 and the phasing of shipments in several 
  countries. 
  In International, sales grew 5% to GBP558 million on a reported basis 
  but declined 8% pro-forma primarily reflecting the phasing of tenders 
  of a number of products, particularly Synflorix and Boostrix relative 
  to H1 2014. 
  Consumer Healthcare 
  Consumer Healthcare sales in the six months grew 37% on a reported 
  basis and 7% on a pro-forma basis to GBP2,890 million, with strong 
  pro-forma growth in the US and Europe while International pro-forma 
  sales were flat. 
  US turnover increased 56% to GBP690 million (31% pro-forma growth), 
  primarily reflecting the launch of OTC Flonase, with sales of GBP110 
  million in the six months, and a favourable comparison with H1 2014 
  which was impacted by supply constraints. Sensodyne gained a percentage 
  point of market share. 
  Sales of GBP834 million in Europe grew 60% (6% pro-forma) primarily 
  as a result of double-digit growth in Oral health sales, benefiting 
  from improved supply and a number of new product introductions, together 
  with strong Voltaren sales following a new advertising campaign. 
  International sales of GBP1,366 million grew 19% but were flat on 
  a pro-forma basis. Strong growth in Oral health sales and the India 
  business were offset by the negative impact of reducing channel inventories 
  in the acquired consumer businesses, most notably in China, Russia 
  and the Middle East. 
  Corporate and other unallocated turnover 
  The Corporate and unallocated turnover of GBP44 million represented 
  sales of several Vaccines and Consumer Healthcare products, which 
  are being held for sale in a number of markets. GSK is required to 
  dispose of these products in specific markets in order to meet the 
  requirements of the anti-trust approvals for the Novartis transaction.

 HIV operating profit represents the operating profit of ViiV Healthcare. 
 
 
 Core operating profit - Q2 2015 
  Core operating profit was GBP1,349 million, 3% higher in CER terms 
  than in Q2 2014 on a turnover increase of 7%. The core operating margin 
  of 22.9% was 2.4 percentage points lower than in Q2 2014 and 1.0 percentage 
  point lower on a CER basis. The decrease included a 3.5 percentage 
  point impact from the Novartis transaction, reflecting the disposal 
  of GSK's higher margin Oncology business and the acquisition of lower 
  margin Vaccines and Consumer Healthcare businesses from Novartis. 
  On a pro-forma basis core operating profit grew 14% in CER terms compared 
  to Q2 2014 on a turnover increase of 2%. The core operating margin 
  increased on a pro-forma basis by 2.5 percentage points in CER terms, 
  primarily benefiting from the initial phases of the Pharmaceuticals 
  restructuring programme, although an improved product mix offset continued 
  pricing pressure on the cost of sales margin. 
  Cost of sales as a percentage of turnover was 30.2%, up 2.5 percentage 
  points in sterling terms and 2.6 percentage points higher in CER terms 
  than in Q2 2014. On a pro-forma basis the cost of sales percentage 
  decreased 0.1 percentage points and was flat in CER terms. This reflected 
  a more favourable product mix in the quarter driven by strong growth 
  in new products, particularly Tivicay and Triumeq, and a benefit from 
  the Group's cost reduction programmes, offset by adverse price pressure 
  in Pharmaceuticals, primarily respiratory, and increased investments 
  in Vaccines to improve the reliability and capacity of the supply 
  chain. 
  SG&A costs were 35.5% of turnover, 0.9 percentage points higher than 
  in Q2 2014 but 0.2% lower on a CER basis. On a pro-forma basis, SG&A 
  as a percentage of sales decreased by 0.4 percentage points and 1.5 
  percentage points on a CER basis. This primarily reflected savings 
  in Global Pharmaceuticals, including the initial benefits of the Pharmaceuticals 
  cost reduction programme, partly offset by the inherited costs in 
  Consumer Healthcare where synergies are still in the very early stages 
  of delivery. 
  R&D expenditure declined 6% CER to GBP731 million (12.4% of turnover) 
  compared with GBP766 million (13.8% of turnover) in Q2 2014. On a 
  pro-forma basis, R&D expenditure declined 10% reflecting the benefit 
  of cost reduction programmes in Pharmaceuticals and Vaccines as well 
  as the phasing of ongoing project spending. 
  Royalty income was GBP62 million (Q2 2014: GBP72 million). 
  Core operating profit by business - Q2 2015 
  Following the completion of the transaction with Novartis, GSK has 
  reorganised the Group to reflect the greater balance between its Pharmaceuticals, 
  Vaccines and Consumer Healthcare businesses and responsibilities for 
  some parts of these respective businesses have been realigned. GSK 
  is reporting these three businesses separately with corporate costs 
  reallocated to each accordingly so that the profitability of each 
  business is reflected more accurately. 
  Pharmaceuticals core operating profit was GBP1,116 million, 1% lower 
  than in Q2 2014 in CER terms on a turnover decrease of 6%. The core 
  operating margin of 31.5% was 1.0 percentage points higher than in 
  Q2 2014 and 1.7 percentage points higher on a CER basis. On a pro-forma 
  basis, core operating margin increased 2.5 percentage points on a 
  CER basis, primarily reflecting strong growth in HIV, partly offset 
  by continued pricing pressure in Global Pharmaceuticals, primarily 
  respiratory products, and the initial benefits of the restructuring 
  programmes in Pharmaceuticals and R&D. 
  Vaccines operating profit was GBP177 million, 32% lower than in Q2 
  2014 in CER terms on a turnover increase of 11%. The core operating 
  margin of 21.7% was 10.7 percentage points lower than in Q2 2014 and 
  down 12.5% on a CER basis, primarily driven by the cost base of the 
  former Novartis Vaccines business. The pro-forma margin declined 1.3 
  percentage points which primarily reflected mix changes in the quarter 
  and additional supply chain investments, partly offset by reductions 
  in R&D. 
  Consumer Healthcare core operating profit was GBP108 million, 41% 
  higher than in Q2 2014 in CER terms on a turnover increase of 51%. 
  The core operating margin of 7.2% was 2.9 percentage points lower 
  than in Q2 2014, and 0.7 percentage points lower on a CER basis. On 
  a pro-forma basis, the Consumer Healthcare operating margin was 0.6 
  percentage points lower, driven by a one-off sales tax settlement 
  which impacted the operating margin by 1.3%, along with the net effect 
  of the inherited Novartis cost base and the limited integration benefits 
  to date, given the early stage of this programme. 
  Core operating profit - H1 2015 
  Core operating profit was GBP2,654 million, 6% lower than in H1 2014 
  in CER terms on a turnover increase of 4%. The core operating margin 
  of 23.1% was 3.2 percentage points lower than in H1 2014, 2.5 percentage 
  points lower on a CER basis. This decline included a 2.4 percentage 
  point impact of the Novartis transaction reflecting the disposal of 
  GSK's higher margin Oncology business and the acquisition of lower 
  margin Vaccines and Consumer Healthcare businesses from Novartis. 
  On a pro-forma basis the operating margin declined 0.1 percentage 
  points which primarily reflected an increase in cost of sales as a 
  percentage of turnover partly offset by reduced SG&A and R&D percentages. 
  Cost of sales as a percentage of turnover was 30.6%, 2.9 percentage 
  points higher than in H1 2014. On a pro-forma basis, the cost of sales 
  percentage increased 1.1 percentage points and 1.3 percentage points 
  on a CER basis. This reflected adverse price movements, particularly 
  in US Global Pharmaceuticals, increased investments in Vaccines to 
  improve the reliability and capacity of the supply chain and an adverse 
  comparison to the reduced cost of sales in Vaccines in H1 2014, which 
  benefited from a number of inventory adjustments. These declines were 
  partly offset by improved product mix, as a result of the growth in 
  HIV products, and the benefits of the Group's ongoing cost reduction 
  programmes. 
  SG&A costs as a percentage of sales were 34.4%, 1.0 percentage points 
  higher than in H1 2014 and 0.5 percentage points higher on a CER basis. 
  On a pro-forma basis, SG&A costs increased 0.1 percentage point, but 
  decreased 0.4 percentage points on a CER basis, This primarily reflected 
  declines in Global Pharmaceuticals, including the initial benefits 
  of the Pharmaceuticals cost reduction programme, partly offset by 
  the inherited costs in the Novartis Consumer Healthcare businesses 
  where synergies are still in the early stages of delivery. 
  R&D expenditure declined 4% CER to GBP1,520 million (13.2% of turnover) 
  compared with GBP1,550 million (13.9% of turnover) in H1 2014. On 
  a pro-forma basis, R&D expenditure declined 7% reflecting the benefit 
  of cost reduction programmes in Pharmaceuticals and Vaccines as well 
  as the phasing of ongoing project spending. 
  Royalty income was GBP139 million (H1 2014: GBP142 million). 
 
 
  Core operating profit by business - H1 2015 
  Pharmaceuticals core operating profit was GBP2,109 million, 9% lower 
  than in H1 2014 in CER terms on a turnover decrease of 7%. The core 
  operating margin of 29.9% was 1.6 percentage points lower than in 
  H1 2014 and 0.8 percentage points lower on a CER basis. Excluding 
  the impact of the Novartis transaction, on a pro-forma basis, the 
  core operating margin declined 0.5 percentage points on a CER basis, 
  which reflected an increase in cost of sales as a percentage of turnover 
  primarily due to adverse price movements partly offset by favourable 
  mix from growth in HIV products, and declines in the SG&A and R&D 
  percentages, reflecting the benefits of the cost reduction programmes. 
  Vaccines operating profit was GBP338 million, 32% lower than in H1 
  2014 in CER terms on a turnover increase of 11%. The core operating 
  margin of 22.3% was 10.1 percentage points lower than in H1 2014 and 
  12.3% lower on a CER basis, primarily driven by the cost base of the 
  former Novartis Vaccines business. The pro-forma margin declined 3.8 
  percentage points which reflected an increase in cost of sales as 
  a percentage of turnover due to mix changes in the six months, additional 
  supply chain investments and the benefit to H1 2014 of a number of 
  inventory adjustments. 
  Consumer Healthcare core operating profit was GBP290 million, 47% 
  higher than in H1 2014 in CER terms on a turnover increase of 37%. 
  The core operating margin of 10.0% was 0.6 percentage points lower 
  than in H1 2014, but improved 0.9 percentage points on a CER basis. 
  On a pro-forma basis the operating margin increased 1.0 percentage 
  points on a CER basis, due to a significant improvement in gross margin, 
  reflecting benefits from both improved supply and pricing and the 
  US Flonase launch, partly offset by increased investment in SG&A behind 
  new product launches, with synergies on track but still in the early 
  stages of delivery. 
  Core profit after tax and core earnings per share - Q2 2015 
  Net finance expense was GBP178 million compared with GBP156 million 
  in Q2 2014, reflecting the change in the mix of gross debt. The share 
  of losses of associates and joint ventures was GBP2 million (Q2 2014: 
  GBP8 million profit). 
  Tax on core profit amounted to GBP233 million and represented an effective 
  core tax rate of 20.0% (Q2 2014: 22.0%). 
 
  The allocation of earnings to non-controlling interests amounted to 
  GBP99 million (Q2 2014: GBP61 million), the increase reflecting the 
  Consumer Healthcare non-controlling interest allocation together with 
  an increase in the allocation of ViiV Healthcare profits. 
  Core EPS of 17.3p was flat in CER terms compared with a 3% increase 
  in the operating profit primarily as a result of the increased non-controlling 
  interest allocation, partly offset by a lower tax charge. 
 
 
 Core profit after tax and core earnings per share - H1 2015 
  Net finance expense was GBP334 million compared with GBP317 million 
  in H1 2014, reflecting the change in the mix of gross debt. 
  The share of profits of associates and joint ventures was GBP5 million 
  (H1 2014: GBP9 million). In March 2015, GSK reduced its shareholding 
  in its one significant associate, Aspen Pharmacare Holdings Limited, 
  from 12.4% to 6.2% of the issued share capital. As a result, GSK no 
  longer accounts for Aspen as an associate and the contribution from 
  associates and joint ventures in 2015 is expected to be minimal. 
  Tax on core profit amounted to GBP464 million and represented an effective 
  core tax rate of 20.0% (H1 2014: 22.0%). 
  The allocation of earnings to non-controlling interests amounted to 
  GBP190 million (H1 2014: GBP123 million), the increase reflecting 
  the Consumer Healthcare non-controlling interest allocation together 
  with an increase in the allocation of ViiV Healthcare profits. 
  Core EPS of 34.6p decreased 8% in CER terms compared with a 6% decline 
  in the operating profit primarily as a result of the increase in the 
  non-controlling interest allocation, partly offset by a lower tax 
  charge. 
 
 
 Guidance for 2015 
  Core EPS for 2015 is expected to decline at a percentage rate in the 
  high teens (CER) primarily due to continued pricing pressure on Seretide/Advair 
  in US/Europe, the dilutive effect of the Novartis transaction and 
  the inherited cost base of the Novartis businesses. 
 
 
  2016 outlook 
  In 2016, GSK expects to see a significant recovery in core EPS with 
  percentage growth expected to reach double digits on a CER basis as 
  the adverse impacts seen in 2015 diminish and the sales and synergy 
  benefits of the Novartis transaction contribute more meaningfully. 
 
 
 Currency impact 
  The Q2 2015 results are based on average exchange rates, principally 
  GBP1/$1.54, GBP1/EUR1.38 and GBP1/Yen 186. Comparative exchange rates 
  are given on page 43. The period-end exchange rates were GBP1/$1.57, 
  GBP1/EUR1.41 and GBP1/Yen 192. 
 
  In the quarter, turnover increased 7% CER and 6% at actual exchange 
  rates. Core EPS of 17.3p was flat in CER terms and down 9% at actual 
  rates. The negative currency impact reflected the strength of Sterling 
  against the majority of the Group's trading currencies relative to 
  Q2 2014 partly offset by a weakening of Sterling against the US Dollar. 
  Losses on settled intercompany transactions contributed three percentage 
  points of the negative currency impact of nine percentage points on 
  core EPS. 
 
  In H1 2015, turnover increased 4% CER and 3% at actual exchange rates. 
  Core EPS of 34.6p was down 8% in CER terms and down 14% at actual 
  rates. The negative currency impact reflected the strength of Sterling 
  against the majority of the Group's trading currencies relative to 
  H1 2014 partly offset by a weakening of Sterling against the US Dollar. 
  Losses on settled intercompany transactions contributed one percentage 
  point of the negative currency impact of six percentage points on 
  core EPS. 
 
  If exchange rates were to hold at the Q2 2015 period-end rates for 
  the rest of 2015, the estimated adverse impact on 2015 Sterling turnover 
  would be around 2%, and if there were no further exchange gains or 
  losses, the estimated adverse impact on 2015 Sterling core EPS would 
  be around 6%.

  tax and earnings per share to total results are as follows:

 Total operating profit and total earnings per share - Q2 2015 
  Total operating profit was GBP335 million compared with GBP1,137 million 
  in Q2 2014. The non-core items resulted in a net charge of GBP1,014 
  million (Q2 2014: GBP270 million), reflecting the impact of an acceleration 
  in restructuring costs driven by the Novartis transaction and the Pharmaceuticals 
  restructuring programme as well as the impact of further adjustments 
  related to ViiV Healthcare and Consumer Healthcare. 
  The intangible asset amortisation decreased to GBP125 million from 
  GBP152 million in Q2 2014, which included accelerated amortisation 
  on Lovaza. Intangible asset impairments were GBP2 million (Q2 2014: 
  GBP1 million). 
  Major restructuring charges accrued in the quarter were GBP515 million 
  (Q2 2014: GBP101 million), the majority of which are expected to be 
  cash items, reflecting the acceleration of a number of restructuring 
  projects following the completion of the Novartis transaction, as well 
  as further charges for Pharmaceuticals restructuring projects. 
  Legal charges of GBP50 million (Q2 2014: GBP47 million) included settlement 
  of existing anti-trust matters and higher litigation costs. 
  Acquisition accounting and other adjustments resulted in a net charge 
  of GBP322 million (Q2 2014: credit of GBP31 million). This included 
  the unwinding of the discounting effects on both the contingent consideration 
  for the acquisition of the former Shionogi-ViiV Healthcare Joint Venture 
  and on the Consumer Healthcare Joint Venture put option. Other items 
  also included equity investment and asset disposals, one-off required 
  regulatory charges in R&D and certain other adjusting items. The net 
  credit in Q2 2014 included a gain of GBP106 million arising from the 
  termination in Europe of the commercialisation agreement for Prolia 
  with Amgen. 
  A tax charge of GBP37 million on total profits represented an effective 
  tax rate of 24.3% (Q2 2014: 28.8%) and reflected the differing tax 
  effects of the various non-core items. See 'Taxation' on page 42 for 
  further details. 
  Total EPS was 3.1p, compared with 13.6p in Q2 2014, primarily reflecting 
  accelerated investments in transaction benefits in the quarter. 
 
 
 Total operating profit and total earnings per share - H1 2015 
  Total operating profit was GBP9,551 million compared with GBP2,203 
  million in H1 2014. The non-core items resulted in a net credit of 
  GBP6,897 million (H1 2014: net charge of GBP734 million), primarily 
  reflecting the impact of the Novartis transaction. 
  The intangible asset amortisation decreased to GBP276 million from 
  GBP322 million in H1 2014, which included accelerated amortisation 
  on Lovaza. 
  Intangible asset impairments of GBP104 million (H1 2014: GBP49 million) 
  included impairments of several R&D and commercial assets. 
  Major restructuring charges of GBP881 million have been accrued (H1 
  2014: GBP180 million), the majority of which are expected to be cash 
  items, and reflected the acceleration of a number of restructuring 
  projects following completion of the Novartis transaction. The programmes 
  have delivered GBP0.4 billion of incremental benefit compared with 
  H1 2014. 
  Charges to date are GBP1.8 billion, predominantly cash. The total cash 
  charges of the combined restructuring programmes are expected to be 
  approximately GBP3.65 billion and the non-cash charges up to GBP1.35 
  billion. The combined programmes have delivered approximately GBP1.0 
  billion of annual savings on a moving annual total basis and are on 
  track to deliver GBP3 billion of benefits. The combined programme is 
  expected to be largely complete by 2017. 
  Legal charges of GBP135 million (H1 2014: GBP155 million) included 
  settlement of existing anti-trust matters and litigation costs. 
  Acquisition accounting and other adjustments resulted in a net credit 
  of GBP8,293 million (H1 2014: charge of GBP28 million). This included 
  the profit on disposal of the Oncology business to Novartis of GBP9,247 
  million, partly offset by an increase in the liability for the contingent 
  consideration for the acquisition of the former Shionogi-ViiV Healthcare 
  joint venture from remeasurements and the unwinding of the discounting 
  effect of GBP964 million. 
  Other items also included equity investment and asset disposals, one-off 
  required regulatory charges in R&D and certain other adjusting items. 
  The profit on disposal of associates of GBP844 million arose from the 
  disposal of half of GSK's investment in Aspen Pharmacare and the remeasurement 
  of the remaining holding to market value on its reclassification to 
  equity investments. 
  The charge for taxation on total profits amounted to GBP1,922 million 
  and represented a total effective tax rate of 19.1% (H1 2014: 24.8%), 
  reflecting the differing tax effects of the various non-core items. 
  See 'Taxation' on page 42 for further details. 
  Total EPS was 170.7p, compared with 27.5p in H1 2014, the increase 
  primarily reflecting the profits on disposal of the Oncology business 
  and the Aspen Pharmacare shares, partly offset by the increase in the 
  liability for the contingent consideration for the acquisition of the 
  former Shionogi-ViiV Healthcare joint venture and increased major restructuring 
  expenditure.

      adjusted free cash flow and free cash flow conversion are defined 
      on page 28. 
 
 
 Q2 2015 
  The net cash inflow from operating activities for the quarter was GBP217 
  million (Q2 2014: GBP766 million). This was after the payment of non-core 
  restructuring and integration and transaction costs of GBP248 million 
  (Q2 2014: GBP107 million), legal settlements of GBP74 million (Q2 2014: 
  GBP205 million) and the initial tax payment of GBP511 million in the 
  quarter arising on the sale of the Oncology business. Adjusting for 
  these items, each of which has been funded from divestment proceeds, 
  the net cash inflow from operating activities would have been GBP1,050 
  million, broadly similar to the Q2 2014 cash flow of GBP1,078 million. 
  H1 2015 
  The net cash inflow from operating activities for the six months was 
  GBP587 million (H1 2014: GBP1,693 million). This included the payment 
  of non-core restructuring and integration costs of GBP502 million (H1 
  2014: GBP208 million), legal settlements of GBP236 million (H1 2014: 
  GBP246 million) and the initial tax payment arising on the sale of 
  the Oncology business. Adjusting for these items, each of which has 
  been funded from divestment proceeds, the net cash inflow from operating 
  activities would have been GBP1,836 million (H1 2014: GBP2,147 million). 
  The decrease primarily reflected the impact of lower operating profits 
  in the first half. 
  Free cash outflow was GBP675 million for the first half. Excluding 
  non-core restructuring and integration costs, legal payments and the 
  initial tax payment on the sale of the Oncology business, the free 
  cash inflow was GBP574 million (H1 2014: GBP961 million). The decrease 
  primarily reflected the impact of lower operating profits, together 
  with higher payments to non-controlling interests in the six months. 
  Free cash flow conversion was impacted by the profits on the disposals 
  of the Oncology business and the Aspen investments. 
  Net debt 
  At 30 June 2015, net debt was GBP9.6 billion, compared with GBP14.4 
  billion at 31 December 2014, comprising gross debt of GBP17.2 billion 
  and cash and liquid investments of GBP7.6 billion. The decrease in 
  net debt reflected the impact of the Novartis transaction in which 
  GSK sold its Oncology business for net cash proceeds of GBP10.0 billion 
  and paid GBP3.3 billion, net of cash acquired, to purchase the Novartis 
  businesses. An initial tax payment of GBP511 million on the transaction 
  has been made with a significant proportion of the remainder expected 
  to be settled before the end of the year. In addition, GSK sold part 
  of its shareholding in Aspen for cash proceeds of GBP564 million and 
  paid dividends to shareholders of GBP2,035 million. At 30 June 2015, 
  GSK had short-term borrowings (including overdrafts) repayable within 
  12 months of GBP2,472 million with loans of GBP1,271 million repayable 
  in the subsequent year.

 * Working capital conversion cycle is defined on page 28. 
 
 
 Although working capital increased by GBP245 million in the quarter, 
  this had no overall effect on the working capital conversion cycle. 
  In the six months, working capital was significantly impacted by the 
  inclusion of inventory acquired with the former Novartis Vaccines business. 
  The increase was partly offset by favourable exchange effects. 
 
 
 Returns to shareholders 
 
 
 GSK expects to pay an annual ordinary dividend of 80p for each of the 
  next three years (2015-2017). 
  GSK also plans to return approximately GBP1 billion (20p per share) 
  to shareholders via a special dividend to be paid alongside GSK's Q4 
  2015 ordinary dividend payment. 
  Any future returns to shareholders of surplus capital will be subject 
  to the Group's strategic progress, visibility on the put options associated 
  with ViiV Healthcare and the Consumer Healthcare joint venture and 
  other capital requirements. 
  Quarterly dividends 
  The Board has declared a second interim dividend of 19 pence per share 
  (Q2 2014: 19 pence per share). 
  Payment of dividends 
  The equivalent interim dividend receivable by ADR holders will be calculated 
  based on the exchange rate on 29 September 2015. An annual fee of $0.02 
  per ADS (or $0.005 per ADS per quarter) will be charged by the Depositary. 
  The ex-dividend date will be 13 August 2015 (12 August 2015 for ADR

 Respiratory 
  Q2 2015 (GBP1,467 million; down 6%) 
  Respiratory sales in the quarter declined 6% to GBP1,467 million. 
  Seretide/Advair sales were down 13% to GBP960 million, Flixotide/Flovent 
  sales decreased 10% to GBP159 million and Ventolin sales rose 2% to 
  GBP160 million. Relvar/Breo Ellipta recorded sales of GBP53 million 
  and Anoro Ellipta, now launched in the US, Europe and Japan, recorded 
  sales of GBP15 million in the quarter. 
  In the US, Respiratory sales declined 12% to GBP704 million in the 
  quarter (5% volume growth and a 17% negative impact of price and mix). 
  This decline included the price and mix impact of new contracts agreed 
  in 2014 in response to competitive pressures in the ICS/LABA combination 
  market, where Advair and Breo Ellipta compete. Sales of Advair were 
  GBP484 million, down 17% (2% volume decline and a 15% negative impact 
  of price and mix). Flovent sales were down 15% to GBP100 million while 
  Ventolin sales rose 3% to GBP81 million. The reported growth rates 
  for both Flovent and Ventolin reflected the net negative impact of 
  true up adjustments to accruals for returns and rebates recorded in 
  both Q2 2014 and Q2 2015. Excluding the impact of true up adjustments 
  and stocking patterns, on an estimated underlying basis Flovent sales 
  declined 6% while Ventolin grew 19%. Breo Ellipta recorded sales of 
  GBP19 million, and Anoro Ellipta, recorded sales of GBP12 million 
  in the quarter. 
  European Respiratory sales were down 8% to GBP369 million, with Seretide 
  sales down 16% to GBP267 million, reflecting the expected pressures 
  of increased competition from generics and the transition of the Respiratory 
  portfolio to newer products. Relvar Ellipta, approved in Europe for 
  both COPD and asthma, recorded sales of GBP19 million in the quarter, 
  while Anoro Ellipta, with launches now underway in many countries 
  throughout the region, recorded sales of GBP3 million. 
  Respiratory sales in the International region grew 5% to GBP394 million 
  with Emerging Markets up 4% and Japan, benefiting from comparison 
  with a weak Q2 2014, up 17%. In Emerging Markets, sales of Seretide 
  were in line with last year at GBP121 million, while Ventolin grew 
  5% to GBP47 million. In Japan, sales of Relvar Ellipta of GBP13 million 
  in the quarter and a 9% increase in Adoair sales, drove overall Respiratory 
  performance. 
  H1 2015 (GBP2,875 million; down 8%) 
  Respiratory sales in the six months declined 8% to GBP2,875 million. 
  Seretide/Advair sales were down 14% to GBP1,858 million, Flixotide/Flovent 
  sales decreased 16% to GBP312 million and Ventolin sales fell 4% to 
  GBP321 million. Relvar/Breo Ellipta recorded sales of GBP94 million 
  and Anoro Ellipta GBP27 million. 
  In the US, Respiratory sales declined 16% to GBP1,287 million in the 
  six months (3% volume growth and a 19% negative impact of price and 
  mix). Sales of Advair were GBP876 million, down 19% (2% volume decline 
  and a 17% negative impact of price and mix). Flovent sales were down 
  27% to GBP183 million and Ventolin sales fell 12% to GBP159 million. 
  The reported declines for both Flovent and Ventolin reflected the 
  net negative impact of true up adjustments to accruals for returns 
  and rebates recorded in both H1 2014 and H1 2015. Excluding the impact 
  of true up adjustments and stocking patterns, on an estimated underlying 
  basis Flovent sales declined 6% while Ventolin grew 20%. Breo Ellipta 
  recorded sales of GBP33 million, and Anoro Ellipta, recorded sales 
  of GBP21 million in the first half of 2015. 
  European Respiratory sales were down 6% to GBP761 million, with Seretide 
  sales down 14% to GBP558 million, reflecting the expected pressures 
  of increased competition from generics and the transition of the Respiratory 
  portfolio to newer products. Relvar Ellipta, approved in Europe for 
  both COPD and asthma, recorded sales of GBP35 million in the six months 
  while Anoro Ellipta recorded sales of GBP5 million. 
  Respiratory sales in the International region grew 5% to GBP827 million 
  with Emerging Markets up 5% and Japan up 7%. In Emerging Markets, 
  sales of Seretide increased 3% to GBP247 million, while Ventolin grew 
  6% to GBP93 million. In Japan, sales of Relvar Ellipta of GBP22 million, 
  together with strong Avamys and Xyzal sales growth more than offset 
  a 13% decline in Adoair sales. 
  Cardiovascular, metabolic and urology 
  Q2 2015 (GBP242 million; up 5%) 
  Sales in the category rose 5% to GBP242 million. The Avodart franchise 
  fell 2% to GBP192 million, with 9% growth in sales of Duodart/Jalyn 
  offset by a 6% decline in sales of Avodart. In the US, generic competition 
  to both Avodart and Jalyn is expected to begin in Q4 2015. Sales of 
  Prolia increased 38% to GBP11 million, reflecting the impact of the 
  termination of the joint commercialisation agreement with Amgen in 
  a number of European markets, Mexico and Russia in Q2 2014 on the 
  prior period comparative. 
  H1 2015 (GBP460 million; down 2%) 
  Sales in the category fell 2% to GBP460 million in the six months. 
  The Avodart franchise fell 4% to GBP371 million, with 11% growth in 
  sales of Duodart/Jalyn more than offset by a 10% decline in sales 
  of Avodart. Sales of Prolia declined 9% to GBP20 million, reflecting 
  the termination in Q2 2014 of the joint commercialisation agreement 
  with Amgen. 
  Immuno-inflammation 
  Q2 2015 (GBP56 million; up 27%) 
  Immuno-inflammation sales grew 27% to GBP56 million. Benlysta turnover 
  in the quarter was GBP56 million, up 30%. In the US, Benlysta sales 
  were GBP51 million, up 21%. 
  H1 2015 (GBP116 million; up 23%) 
  Immuno-inflammation sales grew 23% to GBP116 million. Benlysta turnover 
  in the first half was GBP107 million, up 27%. In the US, Benlysta 
  sales were GBP97 million, up 24%. 
  Other pharmaceuticals 
  Q2 2015 (GBP542 million; down 6%) 
  Sales in other therapy areas fell 6% to GBP542 million. Dermatology 
  sales declined 8% to GBP105 million adversely affected by supply constraints 
  due to capacity limitations, while Augmentin sales increased 2% to 
  GBP143 million. Relenza sales more than doubled in the quarter to 
  GBP33 million, partly driven by the timing of US CDC orders. Sales 
  of products for Rare diseases rose 2% to GBP94 million, including 
  sales of Volibris which were up 8% compared with Q2 2014. 
  H1 2015 (GBP1,067 million; down 7%) 
  Sales in other therapy areas fell 7% to GBP1,067 million in the six 
  months. Augmentin sales were down 1% at GBP283 million and Dermatology 
  sales declined 10% to GBP214 million in part adversely affected by 
  supply constraints due to capacity limitations. Relenza sales were 
  up 33% to GBP63 million driven by the timing of US CDC orders. Sales 
  of products for Rare diseases declined 4% to GBP185 million, primarily 
  as a result of generic competition to Mepron in the US. 
  Established Products 
  Q2 2015 (GBP655 million; down 5%) 
  Established Products turnover fell 5% to GBP655 million with sales 
  in the US down 16% to GBP168 million. Lovaza sales fell 22% to GBP24 
  million, as the impact of generic competition started to annualise. 
 
  Europe was down 13% to GBP121 million, with Serevent sales down 23% 
  to GBP9 million. International was up 3% to GBP366 million, with higher 
  sales of Amoxil, up 77% to GBP22 million, and Valtrex, up 71% to GBP33 
  million, following the regaining of exclusivity in Canada until October 
  2015. These gains were partly offset by a 26% decline in sales of 
  Zeffix in China. 
  H1 2015 (GBP1,305 million; down 13%) 
  Established Products turnover fell 13% to GBP1,305 million in the 
  six months. Sales in the US were down 31% to GBP331 million, primarily 
  reflecting a 64% fall in sales of Lovaza. 
 
  Europe was down 14% to GBP253 million, with Seroxat sales falling 
  18% to GBP17 million, reflecting increased generic competition to 
  a number of other products and a number of supply constraints. International 
  was down 3% to GBP721 million, primarily reflecting lower sales of 
  Seroxat/Paxil due to generic competition in Japan and of Zeffix in 
  China, partly offset by increased Valtrex sales following the regaining 
  of exclusivity in Canada in late 2014. 
 
 
 HIV 
  Q2 2015 (GBP559 million; up 59%) 
  HIV sales increased 59% to GBP559 million in the quarter, with the 
  US up 84%, Europe up 46% and International up 26%. The growth in all 
  three regions was driven by Tivicay and Triumeq. 
  The ongoing roll-out of Tivicay resulted in sales of GBP145 million 
  and Triumeq, now launched in the US and much of Europe recorded sales 
  of GBP149 million in the quarter. Epzicom/Kivexa, which benefited 
  from use in combination with Tivicay, increased 1% to GBP185 million, 
  but Selzentry sales fell 18% to GBP31 million. There were also continued 
  declines in the mature portfolio, mainly driven by generic competition 
  to both Combivir, down 44% to GBP9 million, and Lexiva, down 10% to 
  GBP18 million. 
  H1 2015 (GBP1,005 million; up 51%) 
  Sales increased 51% to GBP1,005 million in the six months, with the 
  US up 76%, Europe up 40% and International up 18%. 
  Tivicay sales were GBP257 million in the six months and Triumeq sales 
  were GBP230 million. Epzicom/Kivexa sales increased 1% to GBP361 million, 
  but Selzentry declined 14% to GBP61 million. Combivir and Lexiva sales 
  fell 41% and 19%, respectively.

 Q2 2015 (GBP814 million; up 11%) 
  Vaccines sales grew 11% to GBP814 million with the US up 13%, Europe 
  up 27% and International down 2%. The business benefited from the 
  sales of the newly-acquired products, primarily Bexsero in Europe 
  and Menveo in the US. On a pro-forma basis, sales for the quarter 
  declined by 5%, primarily reflecting the phasing of tenders in International 
  markets for Synflorix and Havrix, together with competitive pressures 
  on Infanrix/Pediarix. 
  In the US, reported sales grew 13% to GBP240 million but declined 
  5% on a pro-forma basis. This was largely attributable to the 12% 
  decline in Infanrix/Pediarix sales as a result of the return to the 
  market of a competitor vaccine during 2014, partly offset by growth 
  in the Meningitis portfolio and in Rotarix and Boostrix sales. 
  In Europe, sales grew 27% on a reported basis (12% pro-forma) to GBP274 
  million. This growth primarily reflected increased sales of Bexsero, 
  mainly driven by the UK NHS immunisation programme, Portugal and Italy. 
  The quarter also benefited from improved supplies of Boostrix, up 
  31%. The growth was partly offset by a 15% decline in sales of Hepatitis 
  vaccines, reflecting supply constraints as well as tender phasing, 
  together with an Infanrix/Pediarix sales decline of 3%, impacted by 
  the introduction of a competitor vaccine during 2014 and the phasing 
  of shipments in several countries. 
  International sales of GBP300 million declined 2% on a reported basis 
  and 16% on a pro-forma basis. This primarily reflected a decline in 
  sales in Brazil, the Middle East and North Asia due to the phasing 
  of tenders, partly offset by growth of Synflorix in Africa. 
 
 
 H1 2015 (GBP1,513 million; up 11%) 
  Vaccines sales grew 11% to GBP1,513 million with the US up 14%, Europe 
  up 15% and International up 5%. The business benefited from the sales 
  of the newly acquired products, particularly the Meningitis portfolio 
  in Europe and the US. Pro-forma sales declined by 1% primarily due 
  to the phasing of Synflorix shipments in International markets and 
  a decline in Infanrix/Pediarix, following the return to the market 
  of a competitor vaccine during 2014, partly offset by strong growth 
  in Bexsero. 
  In the US, reported growth of 14% (2% pro-forma) to GBP457 million 
  mainly reflected growth in Hepatitis vaccines, Rotarix and Boostrix, 
  benefiting from CDC stockpile order timing, and wholesaler inventory 
  replenishment. Infanrix/Pediarix sales declined 12% as a result of 
  the return to the market of a competitor vaccine during 2014. 
  In Europe, sales grew 15% on a reported basis (5% pro-forma) to GBP498 
  million. This growth primarily reflected increased Bexsero sales mainly 
  driven by the UK NHS immunisation programme, Portugal and Italy. The 
  six months also benefited from the improved supply of Boostrix (up 
  29%) and MMRV (up 8%). The growth was partly offset by a 10% decline 
  in sales of Hepatitis vaccines, largely due to supply constraints 
  as well as tender phasing, together with a 6% decline in Infanrix/Pediarix 
  sales resulting from the introduction of a competitor vaccine during 
  2014 and the phasing of shipments in several countries. 
  International sales of GBP558 million grew 5% on a reported basis 
  but declined 8% on a pro-forma basis. Sales of a number of products, 
  including Boostrix and Synflorix, declined as a result of the phasing 
  of tenders in Brazil, the Middle East and North Asia.

 Q2 2015 (GBP1,509 million; up 51%) 
  The Consumer Healthcare business represents the Consumer Healthcare 
  Joint Venture with Novartis together with the GSK Consumer Healthcare 
  listed businesses in India and Nigeria, which are excluded from the 
  Joint Venture. 
 
  Turnover grew 51% to GBP1,509 million, benefiting significantly from 
  the first full quarter's sales of the newly-acquired products. On 
  a pro-forma basis, growth was 6% (4% volume and 2% price), principally 
  reflecting strong growth in the US following the launch of Flonase 
  OTC. Momentum from key Q1 launches continued to drive innovation contribution, 
  with sales from product introductions in the last three years representing 
  approximately 15% of the quarter's sales. Estimated in-market consumption 
  of GSK Consumer Healthcare brands grew slightly ahead of the global 
  market growth of approximately 6% in the quarter. 
  US sales grew 66% on a reported basis to GBP360 million, and 28% on 
  a pro-forma basis. Flonase was the region's primary growth driver 
  and with quarterly sales of GBP45 million the brand has contributed 
  to the category growth of 15%, achieving 11% market share in the quarter. 
  Oral health sales were driven by Sensodyne, which continued its strong 
  performance with growth of 27%, helped by improved supply and the 
  launch of Sensodyne Repair and Protect Whitening. Excedrin grew 25% 
  in the quarter, outperforming the category which grew at 6%, due to 
  a strong base business performance combined with new variant launches 
  and a price increase. Nicorette Mini lozenges and alli continued their 
  recovery from supply shortages in 2014 and Tums started to recover 
  from the Q1 interruptions. 
 
  Sales in Europe grew 90% on a reported basis to GBP470 million and 
  7% pro-forma. Oral health products reported growth of 11%, helped 
  by improved supply relative to Q2 2014, but also reflecting strong 
  performances from Sensodyne due to new advertising in key markets 
  and the roll-out of Sensodyne True White in the UK, Sensodyne Repair 
  and Protect in Germany, and Sensodyne Mouthwash across a number of 
  markets together with some supply recovery of Aquafresh. In Wellness, 
  Voltaren grew 18% pro-forma, with strong performances across the region 
  particularly in Germany, with strong marketing support behind a new 
  advertising campaign. 
  International sales of GBP679 million grew 27% on a reported basis 
  but declined 2% pro-forma. India continued to perform well with double-digit 
  pro-forma growth reflecting distribution expansion, enhanced marketing 
  campaigns ("Drink Daily, Grow Daily" and "Power of Milk") and the 
  achievement of a four-year market share high for Horlicks. Oral health 
  sales continued to grow in the region, up 9%, driven by Sensodyne. 
  Sales in Wellness were affected by the negative impact of reducing 
  channel inventories in the acquired consumer businesses. 
 
 
 H1 2015 (GBP2,890 million; up 37%) 
  Turnover grew 37% to GBP2,890 million, benefiting significantly from 
  the sales of the newly-acquired products included in the Joint Venture. 
  On a pro-forma basis, growth was 7% (5% volume and 2% price), primarily 
  reflecting strong growth in the US following the launch of Flonase 
  OTC. Sales from new GSK innovations (product introductions within 
  the last three years on a rolling basis) represented approximately 
  15% of sales. Other key 2015 launches to date include Fenbid Chewable 
  in China, Sensodyne Repair and Protect Whitening in the US and Germany, 
  and the roll-out of Sensodyne Mouthwash. 
  US sales grew 56% on a reported basis to GBP690 million, and 31% on 
  a pro-forma basis, partly reflecting a favourable comparison with 
  H1 2014 which was impacted by supply constraints. Flonase was the 
  region's principal growth driver with year to date sales of GBP110 
  million. Oral health sales were again driven by Sensodyne, up 20%, 
  with the launch of Sensodyne Repair and Protect Whitening. Sensodyne 
  gained a percentage point of market share in the six months. Excedrin 
  grew 17% as a result of the launch of new variants and a price increase. 
  Nicorette Mini lozenges and alli returned to the market but Tums supply 
  was constrained. 
  Sales in Europe grew 60% on a reported basis to GBP834 million and 
  grew 6% pro-forma. Oral health products reported growth of 10%, reflecting 
  strong performances from both Sensodyne and Aquafresh following an 
  improved supply position compared with H1 2014, new advertising in 
  key markets, and the roll out of new Sensodyne variants across the 
  region. Wellness recorded 7% pro-forma growth, driven by regional 
  Respiratory brands, which benefited from a strong cold and flu season, 
  and a strong Voltaren performance across the region with 16% pro-forma 
  growth. 
 
  International sales of GBP1,366 million grew 19% on a reported basis 
  and were flat pro-forma. India and South Africa reported double-digit 
  pro-forma growth. Oral health sales grew strongly at 10% across the 
  region and Gastro-intestinal health sales grew 8%, driven by Eno in 
  India and Brazil. Overall Wellness growth was affected by a 20% decline 
  in Panadol sales in Australia, largely due to private label competition 
  and lower sales of Contac in China due to consumer trends towards 
  milder remedies, combined with the negative impacts of reducing channel 
  inventories in the acquired consumer businesses. In Nutrition, Horlicks 
  was up 4%, with strong sales growth in India of 9% as a result of 
  new marketing campaigns, partly offset by some retailer destocking 
  in South East Asia.

 At its Investor day on 6 May 2015, GSK identified a series of New 
  Pharmaceutical and Vaccine products that were expected to deliver 
  at least GBP6 billion of revenues per annum on a CER basis by 2020. 
  Those products, plus current clinical pipeline assets, Nucala and 
  Shingrix, are as set out above and, as a group are defined as New 
  Pharmaceutical and Vaccine products. 
 
  Sales of New Pharmaceutical and Vaccine products were GBP446 million, 
  grew GBP322 million pro-forma in Sterling terms, a rate in excess 
  of 100% CER, in the quarter and represented approximately 10% of Pharmaceuticals 
  and Vaccines turnover. 
 
  In the six months, sales of New Pharmaceutical and Vaccine products 
  were GBP715 million, grew GBP542 million pro-forma in Sterling terms, 
  a rate in excess of 100% CER, and represented approximately 8% of 
  Pharmaceuticals and Vaccines turnover. 
 
 
 Research and development 
 
 
 GSK remains focused on delivering an improved return on its investment 
  in R&D. Sales contribution, reduced attrition and cost reduction are 
  all important drivers of an improving 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 operations of Pharmaceuticals R&D are broadly split into Discovery 
  activities (up to the completion of Phase IIa trials) and Development 
  work (from Phase IIb onwards) each supported by specific and common 
  infrastructure and other shared services where appropriate. R&D expenditure 
  for Q2 2015 is analysed below.

 Core results 
  Core results exclude the following items from total results: amortisation 
  and impairment of intangible assets (excluding computer software) 
  and goodwill; major restructuring costs, including those costs following 
  material acquisitions; legal charges (net of insurance recoveries) 
  and expenses on the settlement of litigation and government investigations, 
  and acquisition accounting adjustments for material acquisitions, 
  disposals of associates, products and businesses, other operating 
  income other than royalty income, and other items, together with the 
  tax effects of all of these items. GSK believes this approach provides 
  a clearer view of the underlying performance of the core business 
  and should make the Group's results more comparable with the majority 
  of its peers. 
 
  CER 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. All commentaries 
  are presented in terms of CER growth, unless otherwise stated. 
 
  Pro-forma growth 
  The Novartis transaction completed on 2 March 2015 and so GSK's reported 
  results include the results of the former Novartis Vaccines and Consumer 
  Healthcare businesses and exclude the results of the former GSK Oncology 
  products, both from 2 March. Pro-forma growth rates are calculated 
  comparing reported turnover for Q2 or H1 2015 with the turnover for 
  Q2 or H1 2014 adjusted to include the equivalent results of the former 
  Novartis Vaccines and Consumer Healthcare businesses and to exclude 
  the results of the former GSK Oncology products from 2 March 2014. 
 
  Full-year 2014 pro-forma results 
  Pro-forma results for the full-year 2014, where provided, include 
  the following major adjustments: (i) the exclusion of Oncology, (ii) 
  the inclusion of 12 months of the acquired Novartis Consumer and Vaccines 
  businesses, (iii) reallocation of most corporate costs to more accurately 
  reflect the profitability of each segment and (iv) the reallocation 
  of divestments required to Corporate and other unallocated costs. 
  Pro-forma 2014 Corporate and other unallocated operating profit includes 
  a structural benefit of GBP219 million realised in Q3 2014. See "Cautionary 
  statement regarding unaudited pro-forma financial information" on 
  page 29. 
 
  Free cash flow 
  Free cash flow is the net cash inflow from operating activities less 
  capital expenditure, interest and dividends paid to non-controlling 
  interests plus proceeds from the sale of property, plant and equipment 
  and dividends received from joint ventures and associated undertakings. 
  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. 
 
  Adjusted free cash flow 
  Adjusted free cash flow excludes payments made to settle legal disputes. 
 
  Free cash flow conversion 
  Free cash flow conversion is free cash flow as a percentage of earnings 
  excluding after-tax legal charges and legal settlements. 
 
  Adjusted net cash inflow from operating activities 
  Adjusted net cash inflow from operating activities excludes payments 
  made to settle legal disputes. 
 
  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.

 Outlook assumptions and cautionary statements 
 
 
 Assumptions related to 2016-2020 outlook 
  In outlining the expectations for 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 Group's 
  expectation of at least GBP6 billion of revenues per annum on a CER 
  basis by 2020 from products launched in the last three years includes 
  contributions from current pipeline assets mepoluzimab and Shingrix. 
  The Group also expects volume demand for its products to increase, 
  particularly in Emerging Markets. 
 
  The assumptions for the Group's revenue and earnings expectations 
  assume no material mergers, acquisitions, disposals, litigation costs 
  or share repurchases for the Company; and no change in the Group's 
  shareholdings in ViiV Healthcare or Consumer Healthcare. 
 
  The Group's expectations assume successful delivery of the Group's 
  integration and restructuring plans over the period 2016-2020. Material 
  costs for investment in new product launches and R&D have been factored 
  into the expectations given. The expectations are given on a constant 
  currency basis and assume no material change to the Group's effective 
  tax rate. 
 
 
 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 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 2014 and those discussed 
  in Part 2 of the Circular to Shareholders and Notice of General Meeting 
  furnished to the SEC on Form 6-K on 24 November 2014. Any forward 
  looking statements made by or on behalf of the Group speak only as 
  of the date they are made and are based upon the knowledge and information 
  available to the Directors on the date of this report. 
 
 
 Cautionary statement regarding unaudited pro-forma financial information 
  The unaudited pro-forma financial information in this release has 
  been prepared to illustrate the effect of (i) the disposal of the 
  oncology assets, (ii) the Consumer Healthcare Joint Venture (i.e. 
  the acquisition of the Novartis OTC Business), and (iii) the acquisition 
  of the Vaccines business (which excludes the Novartis influenza vaccines 
  business) on the results of the Group as if they had taken place as 
  at 1 January 2014. 
 
  The unaudited pro-forma financial information has been prepared for 
  illustrative purposes only and, by its nature, addresses a hypothetical 
  situation and, therefore, does not represent the Group's actual financial 
  position or results. The unaudited pro-forma financial information 
  does not purport to represent what the Group's financial position 
  actually would have been if the disposal of the Oncology assets, the 
  Consumer Healthcare Joint Venture and the Vaccines acquisition had 
  been completed on the dates indicated; nor does it purport to represent 
  the financial condition at any future date. In addition to the matters 
  noted above, the unaudited pro-forma financial information does not 
  reflect the effect of anticipated synergies and efficiencies associated 
  with the Oncology disposal, the Consumer Healthcare Joint Venture 
  and the Vaccines acquisition. 
 
  The unaudited pro-forma financial information does not constitute 
  financial statements within the meaning of Section 434 of the Companies 
  Act 2006. The unaudited pro-forma financial information in this release 
  should be read in conjunction with the financial statements included 
  in (i) the Group's Q2 2015 earnings report dated 29 July 2015 and 
  furnished to the SEC on Form 6-K, (ii) the Group's Annual Report on 
  Form 20-F for 2014 and (iii) the Circular to Shareholders and Notice 
  of General Meeting furnished to the SEC on Form 6-K on 24 November 
  2014.

 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). The completion of the Novartis 
  transaction on 2 March 2015 has changed the balance of the Group and 
  GSK has changed its segment reporting to reflect this. With effect 
  from 1 January 2015, GSK is reporting results under five segments: 
  Global Pharmaceuticals, ViiV Healthcare, Pharmaceuticals R&D, Vaccines 
  and Consumer Healthcare and individual members of the CET are responsible 
  for each segment. Comparative information has been restated accordingly. 
  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. 
  The Pharmaceuticals R&D segment is the responsibility of the Head 
  of Research & Development and is reported as a separate segment. 
  Corporate and other unallocated costs include the results of several 
  Vaccines and Consumer Healthcare products which are being held for 
  sale in a number of markets in order to meet anti-trust approval requirements, 
  together with the costs of corporate functions.

 Legal matters 
  The Group is involved in significant legal and administrative proceedings, 
  principally product liability, intellectual property, tax, anti-trust 
  and governmental investigations as well as related private litigation, 
  which are more fully described in the 'Legal Proceedings' note in 
  the Annual Report 2014. 
  At 30 June 2015, the Group's aggregate provision for legal and other 
  disputes (not including tax matters described under 'Taxation' below) 
  was GBP0.4 billion (31 December 2014: GBP0.5 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 developments since the Annual Report 
  2014 and the quarter ended 31 March 2015. 
  Developments with respect to tax matters are described in 'Taxation' 
  below. 
 
 
 Taxation 
  There have been no material changes to historical tax matters since 
  the publication of the Annual Report. Issues in relation to taxation 
  are described in the 'Taxation' note in the Annual Report 2014. 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 core profits amounted to GBP233 million and 
  represented an effective core tax rate of 20.0% (Q2 2014: 22.0%). 
  The charge for taxation on total profits amounted to GBP37 million 
  and represented an effective tax rate of 24.3% (Q2 2014: 28.8%). 
  In H1 2015, tax on core profits amounted to GBP464 million and represented 
  an effective core tax rate of 20.0% (H1 2014: 22.0%). The charge for 
  taxation on total profits amounted to GBP1,922 million and represented 
  an effective tax rate of 19.1% (H1 2014: 24.8%). 
  The core tax rate for the full year is also expected to be around 
  20%. The Group's balance sheet at 30 June 2015 included a tax payable 
  liability of GBP1,827 million, which includes the remaining taxation 
  payable on the Oncology disposal, and a tax recoverable asset of GBP96 
  million.

  information' above. 
  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 2014 were published

  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 Q2 2015, average sterling exchange rates were stronger against 
  the Euro and the Yen, but weaker against the US Dollar, compared with 
  the same period in 2014. Similarly, during the six months ended 30 
  June 2015, average sterling exchange rates were stronger against the 
  Euro and the Yen, but weaker against the US Dollar compared with the 
  same period in 2014. Period-end sterling exchange rates were also 
  stronger against the Euro and the Yen, but weaker against the US Dollar.

 At 30 June 2015, 4,834 million shares were in free issue (excluding 
  Treasury shares and shares held by the ESOP Trusts). This compares 
  with 4,804 million shares at 30 June 2014. 
 
 
 Net assets 
 The book value of net assets increased by GBP5,616 million from GBP4,936 
  million at 31 December 2014 to GBP10,552 million at 30 June 2015. 
  This primarily reflects the impact of the profit arising from the 
  disposal of the Group's oncology business to Novartis, the gain on 
  the sale of part of its shareholding in Aspen, partly offset by the 
  remeasurement of the ViiV Healthcare contingent consideration, the 
  Consumer Healthcare acquisition and the dividends paid in the period. 
  The carrying value of investments in associates and joint ventures 
  at 30 June 2015 was GBP85 million, with a market value of GBP159 million. 
  Assets held for sale amounted to GBP204 million at 30 June 2015 (31 
  December 2014: GBP1,156 million). The decrease in the period primarily 
  reflected the realisation of the assets sold to Novartis. 
  At 30 June 2015, the net deficit on the Group's pension plans was 
  GBP1,709 million compared with GBP1,689 million at 31 December 2014. 
  The increase in the net deficit primarily arose from an increase in 
  the UK inflation rate from 3% to 3.2%, together with the impact of 
  the Novartis transaction, partly offset by increases in the rates 
  used to discount UK pension liabilities from 3.6% to 3.8%, and US 
  pension liabilities from 3.8% to 4.2%. 
  At 30 June 2015, the post-retirement benefits provision was GBP1,315 
  million compared with GBP1,397 million at 31 December 2014. The decrease 
  in the provision arose from the increase in the rate used to discount 
  the US provision. 
  In certain circumstances, Novartis has the right to require GSK to 
  acquire its 36.5% shareholding in the Consumer Healthcare joint venture 
  at a market-based valuation. This right is exercisable in certain 
  windows from 2018 to 2035 and may be exercised either in respect of 
  Novartis' entire shareholding or in up to four instalments. If exercised, 
  GSK would not be able to avoid this obligation, and so has recognised 
  a financial liability of GBP6,274 million in Other non-current liabilities 
  as at the end of 30 June 2015. This represents the present value of 
  the estimated amount payable by GSK in the event of full exercise 
  of the right by Novartis. If the market multiples on which this valuation 
  is based were to change by 2%, there would be an impact on the income 
  statement of approximately GBP125 million. 
  In certain circumstances, the other shareholders in ViiV Healthcare, 
  Pfizer (11.7%) and Shionogi (10%) may require GSK to acquire their 
  shareholdings at a market based valuation. Pfizer may request an IPO 
  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. Shionogi may also request GSK to acquire its shareholding 
  in ViiV in certain circumstances and limited windows in 2017, 2020 
  and 2022. 
  At 30 June 2015, the ESOP Trusts held 32.4 million GSK shares against 
  the future exercise of share options and share awards. The carrying 
  value of GBP151 million has been deducted from other reserves. The 
  market value of these shares was GBP439 million. 
  At 30 June 2015, the company held 491.5 million Treasury shares at 
  a cost of GBP6,917 million, which has been deducted from retained 
  earnings. 
 
 
 Contingent liabilities 
 There were contingent liabilities at 30 June 2015 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 42. 
 
 
 Business acquisitions and disposals 
 The three-part inter-conditional transaction with Novartis AG involving 
  the Consumer Healthcare, Vaccines and Oncology businesses completed 
  on 2 March 2015. 
  GSK and Novartis have contributed their respective Consumer Healthcare 
  businesses into a Consumer Healthcare Joint Venture in a non-cash 
  transaction. GSK has an equity interest of 63.5% and majority control 
  of the Joint Venture. In addition, GSK has acquired Novartis' global 
  Vaccines business (excluding influenza vaccines) for an initial cash 
  consideration of $5.25 billion with contingent consideration representing 
  subsequent potential milestone payments of up to $1.8 billion arising 
  on the achievement of specified development targets and ongoing royalties 
  based on the future sales performance of certain products, and so 
  the total amount payable is unlimited. The first milestone of $450 
  million (GBP300 million) was paid on 26 March 2015. 
  The fair values of the assets acquired, including goodwill are set 
  out in the table below.

 The non-controlling interest in the Consumer Healthcare Joint Venture 
  calculated applying the full goodwill method represents Novartis' 
  share of the net assets of the joint venture together with attributable 
  goodwill. The goodwill in both businesses acquired represents the 
  potential for synergies arising from combining the acquired businesses 
  with GSK's existing businesses together with the value of the workforce 
  acquired. The majority of the goodwill recognised is not expected 
  to be deductible for tax purposes. Total transaction costs of the 
  acquisitions recognised in both 2014 and 2015 amounted to GBP100 million. 
  Since acquisition on 2 March 2015, turnover of GBP715 million arising 
  from these businesses has been included in Group turnover. If the 
  businesses had been acquired at the beginning of the year, it is estimated 
  that Group turnover in H1 2015 would have been approximately GBP320 
  million higher. These businesses have been integrated into the Group's 
  existing activities and it is not practicable to identify the impact 
  on the Group profit in the period. 
 
 
 GSK has also divested its marketed Oncology portfolio, related R&D 
  activities and rights to its AKT inhibitor and also granted commercialisation 
  partner rights for future oncology products to Novartis for consideration 
  of $16 billion (GBP10,395 million), as follows:

 In addition, GSK completed one small Vaccines business acquisition 
  for cash consideration of GBP120 million, net of cash acquired. This 
  represented goodwill of GBP22 million, intangible assets of GBP124 
  million less other net liabilities of GBP26 million. These amounts 
  are provisional and subject to change. 
 
  GSK also made a small business disposal in the period for net cash 
  consideration of GBP2 million.

 Financial instruments fair value disclosures 
 Certain of the Group's financial instruments are measured at fair 
  value. The following tables categorise these financial assets and 
  liabilities by the valuation methodology applied in determining their 
  fair value. Where possible, quoted prices in active markets are used 
  (Level 1). Where such prices are not available, the asset or liability 
  is classified as Level 2, provided all significant inputs to the valuation 
  model used are based on observable market data. If one or more of 
  the significant inputs to the valuation model is not based on observable 
  market data, the instrument is classified as Level 3.

 Net losses of GBP981 million (2014: net losses of GBP87 million) and 
  net gains of GBP2 million (2014: net gains of GBPnil) attributable 
  to Level 3 financial instruments held at the end of the period were 
  reported in other operating income and other comprehensive income 
  respectively. 
 
  At 30 June 2015, financial liabilities measured using Level 3 valuation 
  methods included GBP2,619 million of contingent consideration for 
  the acquisition of the former Shionogi-ViiV Healthcare joint venture. 
  This consideration is expected to be paid over a number of years and 
  will vary in line with sales of dolutegravir and other compounds. 
  The financial liability is measured at the present value of expected 
  future cash flows, the most significant inputs to the valuation model 
  being future sales forecasts and market interest rates. 
 
  At 30 June 2015, financial liabilities measured using Level 3 valuation 
  methods included GBP303 million of contingent consideration for the 
  acquisition of the Novartis Vaccines business. This consideration 
  is expected to be paid out over a number of years and will vary in 
  line with product sales and the achievement of certain milestone targets. 
  The financial liability is measured at the present value of expected 
  future cash flows, the most significant inputs to the valuation model 
  being future sales forecasts, market interest rates and probability 
  of success in achieving milestone targets. 
 
 
 The table below shows, on an indicative basis, the income statement 
  and balance sheet sensitivity to reasonably possible changes in key 
  inputs to the valuation of this liability.

 The Group transfers financial instruments between different levels 
  in the fair value hierarchy when, as a result of an event or change 
  in circumstances, the valuation methodology applied in determining 
  their fair values alters in such a way that it meets the definition 
  of a different level. There were no transfers between the Level 1 
  and Level 2 fair value measurement categories in the period. Transfers 
  from Level 3 relate to equity investments in companies which were 
  listed on stock exchanges during the period. 
 
 
 The following methods and assumptions were used to measure the fair 
  value of the significant financial instruments carried at fair value 
  on the balance sheet: 
 --   Liquid investments - based on quoted market prices or calculated 
       based on observable inputs in the case of marketable securities; 
       based on principal amounts in the case of non-marketable securities 
       because of their short repricing periods 
 
 --   Other investments - equity investments traded in an active market 
       determined by reference to the relevant stock exchange quoted bid 
       price; other equity investments determined by reference to the current 
       market value of similar instruments or by reference to the discounted 
       cash flows of the underlying net assets 
 
 --   Contingent consideration for business acquisitions after 1 January 
       2010 - based on present value of expected future cash flows 
 
 --   Interest rate swaps and foreign exchange contracts - based on the 
       present value of contractual cash flows using market-sourced data 
       (exchange rates or interest rates) at the balance sheet date 
 
 --   Company-owned life insurance policies - based on cash surrender 
       value 
 
 
 There are no material differences between the carrying value of the 
  Group's other financial assets and liabilities and their estimated 
  fair values, with the exception of bonds, for which the carrying values 
  and fair values are set out in the table below:

 The following methods and assumptions are used to estimate the fair 
  values of financial assets and liabilities which are not measured 
  at fair value on the balance sheet: 
 --   Cash and cash equivalents - approximates to the carrying amount 
 
 --   Short-term loans, overdrafts and commercial paper - approximates 
       to the carrying amount because of the short maturity of these instruments 
 
 --   Long-term loans - based on quoted market prices in the case of the 
       European and US Medium term notes and other fixed rate borrowings; 
       approximates to the carrying amount in the case of floating rate 
       bank loans and other loans 
 
 --   Receivables and payables - approximates to the carrying amount 
 
 --   Lease obligations - approximates to the carrying amount 
 
 --   Other non-current liabilities - approximates to the carrying amount

 Independent review report to GlaxoSmithKline plc 
 
 
 Report on the condensed financial information 
 
  Our conclusion 
  We have reviewed the condensed financial information, defined below, 
  in the Results Announcement of GlaxoSmithKline plc for the three and 
  six months ended 30 June 2015. Based on our review, nothing has come 
  to our attention that causes us to believe that the condensed financial 
  information is not prepared, in all material respects, in accordance 
  with International Accounting Standard 34 as adopted by the European 
  Union and the Disclosure and Transparency Rules of the United Kingdom's 
  Financial Conduct Authority. 
 
  This conclusion is to be read in the context of what we say in the 
  remainder of this report. 
 
 What we have reviewed 
  The condensed financial information, which is prepared by GlaxoSmithKline 
  plc, comprises: 
 
 --    the balance sheet at 30 June 2015; 
 --    the income statement and statement of comprehensive income for the 
        three and six month periods then ended; 
 --    the cash flow statement for the six month period then ended; 
 --    the statement of changes in equity for the six month period then 
        ended; and 
 --    the accounting policies and basis of preparation and related notes 
        on pages 39 to 50 (excluding the Pharmaceuticals and Vaccines turnover 
        tables). 
 
 As disclosed on page 43, the financial reporting framework that has 
  been applied in the preparation of the full annual financial statements 
  of the Group is applicable law and International Financial Reporting 
  Standards (IFRSs) as adopted by the European Union. 
 
  The condensed financial information included in the Results Announcement 
  has been prepared in accordance with the accounting policies set out 
  in the accounting policies and basis of preparation section on page 
  43. 
 
  What a review of condensed financial information involves 
  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 enquiries, 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 Ireland) 
  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. 
 
  We have read the other information contained in the Results Announcement 
  and considered whether it contains any apparent misstatements or material 
  inconsistencies with the information in the condensed financial information. 
 
  Responsibilities for the condensed financial information and the review 
 
  Our responsibilities and those of the directors 
  The Results Announcement, 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 
  in accordance with the Disclosure and Transparency Rules of the United 
  Kingdom's Financial Conduct Authority. 
 
  Our responsibility is to express to the Company a conclusion on the 
  condensed financial information in the Results Announcement based 
  on our review. This report, including the conclusion, has been prepared 
  for and only for the Company for the purpose of complying with the 
  Disclosure and Transparency Rules of the Financial Conduct Authority 
  and for no other purpose. We do not, in giving this conclusion, accept 
  or assume responsibility for any other purpose or to any other person 
  to whom this report is shown or into whose hands it may come save 
  where expressly agreed by our prior consent in writing.

 Notes: 
 
 (a)   The maintenance and integrity of the GlaxoSmithKline plc website 
        is the responsibility of the directors; the work carried out by 
        the auditors does not involve consideration of these matters and, 
        accordingly, the auditors accept no responsibility for any changes 
        that may have occurred to the condensed financial information 
        since it was initially presented on the website. 
 
 (b)   Legislation in the United Kingdom governing the preparation and 
        dissemination of condensed financial information may differ from 
        legislation in other jurisdictions.
