Pre-Quarterly Results Communication Q3 2020

Issued: Thursday 8th October 2020

This Q3 2020 Pre-Quarterly Results Communication has been prepared by GSK in accordance with our standard prior practice. This Communication includes statements made previously by GSK in communications such as our Q2 2020 results presentation on 29 July 2020, our Q2 2020 press release, and our Q2 2020 results analyst/investor call. These statements are extracted from their original source and therefore, by definition, do not reflect subsequent or recent events, circumstances or developments, including divestments and the impact of the coronavirus outbreak (see "Historic London Stock Exchange announcements (LSE announcements) and press releases").

Any updates to these and other previously made statements would only be included in further communications by GSK to the market in our Q3 2020 release or otherwise. Accordingly, the extracted statements should only be taken as speaking as at the date they were originally made, and the inclusion of the extracted statements herein should not be taken as an indication that they will not be updated in the future.

As our Q2 results announcement indicated, the potential impact of the COVID-19 pandemic on GSK's trading performance and all our Principal risks has been assessed with mitigation plans put in place. The pandemic, has as anticipated, impacted the Group performance during the first half of 2020 primarily in demand for Vaccines as a result of containment measures impacting customers' ability and willingness to access vaccination services across all regions. We continue to monitor the situation closely, as this is clearly a very dynamic and uncertain situation, with the ultimate severity, duration and impact unknown at this point including the potential impacts on trading results, our clinical trials, our supply continuity and our employees. The situation could change at any time and there can be no assurance that COVID-19 will not have a material adverse impact on the future results of the Group.

New information for Q3 2020

Foreign exchange

On the basis of the rates in the table below, it is expected that the impact of foreign exchange on Q3 2020 sales will be around -5%. As a result of the mix of currency movements relative to the mix of costs, we expect that the negative impact of foreign exchange on Q3 2020 sterling Adjusted EPS will be greater than the negative impact on sales.

Foreign exchange: Ready reckoner

In the 2019 FY results presentation on 5 February 2020, the following ready reckoner was provided on slide 44 to help estimate the expected impact of foreign exchange movements on adjusted EPS*:

Currency

Impact on 2020 full year adjusted EPS

US dollar

10 cents movement in average exchange rate for full year

impacts EPS by approximately +/-5.5%

Euro

Japanese yen

10 yen movement in average exchange rate for full year

impacts EPS by approximately +/-1.0%

*Please note that the ready reckoner does not include the impact of inter-company exchange gains or losses

The slide also included 2019 currency sales exposure for GSK:

‡The other currencies that each represent more than 1% of Group sales are: Australian dollar, Brazilian real, Canadian dollar, Chinese yuan, Indian rupee and Russian rouble. In total, they accounted for 13% of Group revenues in 2019

Currency impact 2020

In the Q2 2020 press release we made the following comment on the potential impact of currencies on sales and EPS in 2020:

"If exchange rates were to hold at the closing rates on 30 June 2020 ($1.23/£1, €1.10/£1 and Yen

132/£1) for the rest of 2020, the estimated impact on 2020 Sterling turnover growth would be around flat and if exchange gains or losses were recognised at the same level as in 2019, the estimated impact on 2020 Sterling Adjusted EPS growth would also be around flat."

We will update you on our latest view on the estimated impact of currencies in 2020 in our Q3 2020 press release on 28 October.

Dividend

In the Q2 2020 press release we made the following comments regarding the dividend:

"The Board currently intends to maintain the dividend for 2020 at the current level of 80p per share, subject to any material change in the external environment or performance expectations. Over time, as free cash flow strengthens, it intends to build free cash flow cover of the annual dividend to a target range of 1.25-1.50x, before returning the dividend to growth."

On the Q2 2020 results analyst/investor call Iain Mackay made the following comments regarding the Pharmaceuticals business:

"As expected, the COVID-19 related customer stock-building in Q1, predominantly in Europe and the US, broadly reversed in Q2 with only a minor dolutegravir impact in Europe and the US remaining. We estimate that the impact of the stocking reversal on growth in Q2 was approximately 4%.

For the first six months, Pharma revenues were flat CER.

We continue to expect Pharma sales to decline slightly in 2020, excluding divestments."

On the Q2 2020 results analyst/investor call Emma Walmsley made the following comments regarding Respiratory:

"Sales in our Respiratory portfolio are performing strongly. With Trelegy, we continue to lead the market as a single inhaler triple therapy and also grow the market, with sales up 58% in Q2. We are looking forward to the FDA's decision, too, on the asthma indication for Trelegy later this year.

For Nucala, we continue to see strong growth, aided by strong uptake of at-home administration. We are retaining leadership in all key markets and expanding our label in other eosinophilic indications, which will further cement our leadership."

On the Q2 2020 results analyst/investor call Iain Mackay made the following comments regarding the HIV business:

"In HIV revenues were down 3% with the dolutegravir franchise down 2% globally. Sales were impacted in the quarter by customer destocking following the increased demand in Q1 due to COVID-

19. We continue to see good uptake of the two-drug regimens, however, giving us confidence in the longer-term growth outlook.

Excluding the impact of customer stocking, we estimate that HIV sales would have increased slightly in the quarter and we expect sales to be broadly flat for the full year.

On the same call Emma Walmsley made the following comments on Cabenuva and Rukobia:

"Cabenuva, our first long-acting injectable, has been resubmitted to the FDA for approval and we anticipate the response in early 2021. Rukobia, our first-in-class attachment inhibitor, was approved at the beginning of the month for heavily treatment-experienced adults who are living with HIV."

"For Zejula in the US, the latest Flatiron data, which was for May, already indicated a 50% increase in Zejula share in first-line maintenance to 21%. Although, with the pandemic, we have seen delays in the initiation of chemotherapy and debulking surgery in recent months, which does add a near-term headwind, we remain confident in the long-term outlook for Zejula and there is a lot of opportunity with new guidelines and currently low levels of PARP penetration in first-line maintenance. We continue to believe that Zejula is an important medicine with potentially unique properties."

Vaccines

Sales of vaccines are vulnerable to volatility on a quarterly basis - particularly in emerging markets. Since quarterly sales can be very lumpy due in part to the impact of large tenders as well as competitor outages, we highlight in the table below the 2019 and 2020 quarterly results for the Vaccines business.

On the Q2 2020 results analyst/investor call Emma Walmsley made the following comments regarding vaccines overall revenues:

"In Vaccines, despite lockdown impacts on vaccination rates, we believe the underlying demand for our key vaccines, including shingles and meningitis, remains very strong. Guidance from government agencies, including the CDC, is emphasising the importance of routine immunisations and catch-up for all age groups, including adults. We are seeing encouraging signs of recovery in selected geographies in Q3 and we are investing to support it, though there remains some way to go to get back to pre-COVID levels for adult vaccinations such as Shingrix.

We expect to see vaccination rates recover in the second half of the year. We are confident it will come although, clearly, there remains a degree of risk for the exact timing. We continue to work on expanding capacity for Shingrix to support recovery and demand and to enable further launches around the world for this important and much-needed vaccine"

On the Q2 2020 results analyst/investor call in response to a question Luke Miels made the following comments regarding Flu vaccines:

"In the US we expect to ship around 50 million doses in the upcoming season. The manufacturing team has done a great job and we expect those to be in the market shortly. This is a critical part of our acceleration programme for Shingrix, and that's up from 46 million in 2019, which back then was about 19% of market share, and the US is where we send two-thirds of our supply."

On the Q2 2020 results analyst/investor call Iain Mackay made the following comments regarding Consumer Healthcare revenues:

"In Consumer Healthcare on a proforma basis were flat, excluding brands either divested or under review, reflecting the unwind of increased COVID-19 demand we saw in Q1. Including those brands, turnover declined 6% proforma.

At a regional level, China returned to growth as mandated retailer shutdowns were lifted, however this was more than offset by declines in Europe and the US as a result of the pantry loading unwind.

The vitamins, minerals and supplements category continued to grow strongly, with sales growth in the high teens on a proforma basis, this higher demand reflecting an increased consumer focus on health and wellness.

In Pain relief, sales benefited from the continued strong performance of Panadol, and the successful Rx to OTC switch, and launch, of Voltaren OTC in the US. This was offset by an adverse impact on Advil due to initial market misinformation relating to COVID-19 ibuprofen treatment, which has since been corrected. We are also excited about the launch of Advil Dual Action.

Sales also benefited from increased retailer stocking ahead of a systems cutover in North America as part of Pfizer integration activities, which added two percentage points of growth in the quarter, largely in the Digestive health and Pain relief categories. This benefit is expected to reverse in Q3.

Page 10 of 25

We are close to fulfilling our commitment to divest £1 billion of non-core brands in order to refocus our portfolio, as well as funding integration and restructuring activities within Consumer Healthcare."

On the Q2 2020 results analyst/investor call Iain Mackay made the following comments regarding divisional adjusted operating margins:

Pharmaceuticals: "Turning to the Pharma operating margin, as anticipated we saw a decline in Q2 primarily reflecting sales performance while we continue to invest in R&D behind priority assets and promotional activity for new launches. We have maintained a sharp focus on cost management across the business, with focus on increased efficiency in non-customer facing activities."

Vaccines: "The operating margin of 23.4% reflected the impact of reduced sales in the quarter."

Consumer Healthcare: "Operating margin for the quarter was down 120 basis points year on year."

On the Q2 2020 results analyst/investor call Iain Mackay made the following comments regarding net finance expense:

"Interest expense was £227 million. The increase primarily reflects reduced swap interest income on foreign currency hedges and lower interest income on reduced overseas cash, post the close of the divestment of Horlicks and other Consumer Healthcare nutrition products in India. This was partly offset by favourable refinancing of term debt."

*With the introduction of the new R&D strategy in Q2 2018, GSK has revised its definition of free cash flow, a non-IFRS measure, to include proceeds from the sale of intangible assets.

On the Q2 2020 results analyst/investor call Iain Mackay made the following comments regarding cashflow:

"We have delivered cashflow of £2.5 billion in the first half of the year.

The increase primarily reflected a reduction in trade receivables as a result of collections following strong sales in Q1, beneficial timings of payments for returns and taxes, a lower seasonal increase of inventory, and disposals of intangible assets. These were partly offset by higher dividends to non- controlling interests.

Recognising the lower Q2 revenues, and the H1 impact on timing of RAR and tax payments, we anticipate lower free cashflow in the second half. Overall, we still expect cashflow to be a step down from 2019."
