Luke Miels, Chief Executive Officer, GSK:<br><br><br><br><br><br>“GSK<br>has delivered another quarter of strong core results performance,<br>with our key growth drivers performing well. We remain focused on<br>operational delivery, execution, and accelerating<br>R&D.<br><br><br>To that<br>end, we have identified late-stage pipeline accelerations - across<br>18 indications – for 7 key assets in Oncology, Respiratory,<br>Hepatology and Vaccines. Based on clinical data, and their<br>opportunities to improve upon current standards-of-care, we see<br>strong reasons for all these assets to bring meaningful benefits<br>and protection to patients. We have also decided to establish a new<br>flagship R&D Centre on the UK’s Cambridge Biomedical<br>Campus – an investment that will further integrate GSK into<br>one of the world’s leading ecosystems for<br>life-sciences.<br><br><br>To fund<br>investment in the late-stage portfolio and R&D, we are starting<br>a 3-year cost savings programme to simplify the organisation and to<br>reallocate capital and resources. Savings will primarily be<br>reinvested, with some used to improve margins and profitability in<br>the dolutegravir patent expiry period (2028-2030).<br><br><br>We<br>believe these plans, together with continued disciplined capital<br>allocation, will drive strong operational performance and<br>shareholder returns over the next five years, delivering our 2031<br>sales outlook and accelerated long-term growth.”

2026 Guidance

GSK reaffirms its full-year 2026 guidance at constant exchange rates (CER), with further specificity provided below.

Guidance Updated 2026 guidance at CER Previous 2026 guidance at CER
Turnover Increase<br>between 3% to 5%, at the upper half of the range Increase<br>between 3% to 5%
Core<br>operating profit Increase<br>between 7% to 9%, at the upper half of the range Increase<br>between 7% to 9%
Core<br>earnings per share Increase<br>between 7% to 9%, at the lower half of the range Increase<br>between 7% to 9%

This guidance is supported by the following turnover expectations for full-year 2026 at CER.

Turnover expectations New 2026 guidance at CER Previous 2026 guidance at CER
Specialty<br>Medicines Increase<br>at a low double-digit percentage Increase<br>at a low double-digit percentage
Vaccines Broadly<br>stable to an increase at a low single-digit percentage Decline<br>of a low single-digit percentage to broadly stable
General<br>Medicines Decline<br>of a mid-single digit to low single-digit percentage Decline<br>of a low single-digit percentage to broadly stable

Core operating profit is expected to grow at the upper half of the range between 7 to 9 per cent at CER. GSK continues to expect to deliver leverage at a gross margin level due to improved product mix from Specialty Medicines growth and continued operational efficiencies. In addition, GSK anticipates further leverage in Operating profit as we accelerate ongoing productivity initiatives and take a returns-based approach to SG&A investments, with SG&A now expected to be broadly stable. R&D is now expected to grow significantly ahead of sales as we accelerate investments in the pipeline as part of the Accelerate Growth programme while driving operational efficiencies. Royalty income is now expected to be at £850-900 million.

Core earnings per share is also expected to increase at the lower half of the range between 7 to 9 per cent at CER, reflecting higher interest charges of around £800 million, including the impact of the Nuvalent acquisition, and the tax rate which is expected to rise to around 17.5%, offset by the expected benefit from the share buyback programme. Expectations for non-controlling interests remain unchanged relative to 2025.

Agreement with US Government to lower the cost of prescription medicines for American patients

As previously announced, on 19 December 2025, GSK entered into an agreement with the US Administration to lower the cost of prescription medicines for American patients, which, once fully implemented, would exclude both GSK and ViiV Healthcare from Section 232 tariffs for three years. On 9 April 2026, GSK, ViiV Healthcare, and the US Government entered into a definitive agreement reflecting Section 232 tariff relief through 20 January 2029 (subject to final implementation). As part of that implementation, GSK and ViiV Healthcare each signed a Generous Model Manufacturer Participation Agreement with the Centers for Medicare and Medicaid Services effective 15 June 2026. With these agreements GSK and ViiV Healthcare have committed certain products to participate in the voluntary Generous Model, and it is anticipated that supplemental rebate agreements with interested US states will be signed on or before 1 October 2026. Our full year guidance is inclusive of the expected impact of these agreements.

Investing in late-stage product portfolio and Accelerate Growth programme

GSK has 62 assets in clinical development, 19 of which are in phase III development.

The company has strong confidence in its late-stage product portfolio, based on clinical data and the opportunities it has identified to improve upon current standards-of-care. GSK has potential best-in-class products for Oncology, Respiratory, Hepatology, HIV and Vaccines.

Following review, the company has identified asset accelerations - across 18 indications – for 7 late-stage products in Oncology, Respiratory, Hepatology and Vaccines. GSK now also expects to start 20+ phase III trials in 2026 (previously 10).

To accelerate R&D and capture the growth and value the late-stage portfolio offers, GSK has initiated a new “Accelerate Growth” programme. This 3-year programme has two objectives:

(1) Simplify,<br>and match GSK’s organisation and cost base to its evolving<br>product portfolio, notably in Specialty Medicines
(2) Enable<br>the reallocation of GSK’s capital and resources to the<br>late-stage pipeline and to R&D.

The Accelerate Growth programme is targeting £1.9 billion of annual savings, to be fully realised by 2029, for expected total costs of £2.4 billion, of which £2.1 billion is expected to be cash costs. Savings will be primarily reinvested in R&D, including business development activity, with a portion also used to strengthen operating margin in the period related to LoE for dolutegravir (2028-2030). The Accelerate Growth programme will be treated as a Major restructuring programme and costs will be included in Adjusting items. The majority of the cost charges will be in 2026 and 2027.

Cost savings are expected to be enabled by technology and AI and generated by streamlining support services and process redesign including procurement delivery, the reallocation of resources to Specialty Medicines from established products and further simplification of supply chain and the site network to align with portfolio evolution.

The programme, together with delivery of the opportunities in GSK’s late-stage product portfolio, strengthens GSK’s outlooks for growth of: sales of more than £40 billion by 2031; a stable to improving operating margin for the dolutegravir LoE period (2028-2030); and for accelerating growth from 2031 onwards.

Dividend policy

The Dividend policy and the expected pay-out ratio remain unchanged. Consistent with this, GSK has declared a dividend for Q2 2026 of 17p per share. GSK's future dividend policy and guidance regarding the expected dividend pay-out in 2026 are provided on page 30.

In Q2 2026, GSK completed the £2 billion share buyback programme announced in FY 2024.

Exchange rates

If exchange rates were to hold at the closing rates on 20 July 2026 ($1.35/£1, €1.18/£1 and Yen 219/£1) for the rest of 2026, the estimated impact on 2026 Sterling turnover growth for GSK would be -2% and if exchange gains or losses were recognised at the same level as in 2025, the estimated impact on 2026 Sterling Core Operating Profit growth for GSK would be -4%.

Results presentation

A conference call, webcast and in-person event for investors and analysts of the quarterly results will be hosted by Luke Miels, CEO, at 14:00 BST (09:00 EST) on 28 July 2026. Presentation materials will be published on www.gsk.com and a transcript of the webcast will be published subsequently.

Notwithstanding the inclusion of weblinks, information available on the company’s website, or from non GSK sources, is not incorporated by reference into this Results Announcement.

Financial Performance - Core results

Core operating profit growth in Q2 2026 and YTD primarily reflected higher turnover, favourable product and regional mix, and favourable net legal settlements and expenses in Q1 2026 partially offset by increased investment in R&D and new asset launches, as well as lower royalty income in the quarter.

The increase in Core EPS in Q2 2026 primarily reflected the growth in Core operating profit, the share buyback, a lower effective tax rate and lower net finance expenses, partly offset by higher NCIs. YTD Core EPS growth compared to operating profit growth was lower than the quarter principally due to higher net finance costs and a broadly flat effective tax rate.

Reconciliations<br>between Total results and Core results Q2 2026, Q2 2025, H1 2026<br>and H1 2025 are set out on pages 16 and 18

All values are in US Dollars.

Core cost of sales as a percentage of sales decreased in Q2 2026 and YTD primarily due to favourable product and regional mix driven by higher specialty sales and the growth of higher margin Vaccines products, particularly Shingrix in Europe, as well as a favourable comparator due to supply chain optimisation charges incurred in Q2 2025.

Core SG&A increased in Q2 2026 and YTD primarily due to disciplined investment to support launches for new assets including Blenrep and Exdensur as well as a low comparator due to phasing of spend between quarters in Q2 2025. This was partly offset by ongoing productivity initiatives. The YTD also has net favourability on legal settlements and expenses equivalent to around 2ppts impact.

Core R&D investment increased in Q2 2026 and YTD reflecting progression across the portfolio. In Oncology, this included acceleration in work on ADCs Ris-Rez and Mo-Rez, and velzatinib. In Specialty Medicines, increased investment was driven by efimosfermin acquired in Q3 2025, depemokimab COPD indication and all indications of the anti-TSLP monoclonal antibody. Growth was partly offset by lower spend on bepirovirsen which was filed in Q1 2026. Investment also increased on clinical trial programmes associated with mRNA seasonal flu vaccines.

Core royalty income decreased in the quarter and YTD primarily due to Q2 2025 including historic royalties recognised in association with the settlement of an IP dispute, partly offset by higher Kesimpta(1) royalties.

Core net finance expense decreased in Q2 mainly due to a net favourable variance on hedging activities after a negative impact in Q1 2026. Excluding this, core net finance expense increased in Q2 2026 and YTD primarily due to higher net interest on higher net debt following Zantac settlement payments, the share buyback and acquisitions.

The effective tax rate on Core profits was broadly in line with expectations for the year.

Core NCIs in Q2 and YTD were higher primarily due to higher core profit allocations from ViiV Healthcare.

(1) Kesimpta is manufactured by and a trademark of Novartis AG

Financial performance - Total results

Total operating profit decreased in the quarter primarily due to higher impairments and higher CCL charges, partly offset by higher Core operating profit, higher other net operating income and lower NCIs.

Total EPS decreased in Q2 2026 and YTD primarily due to lower Total operating profit driven by higher impairments in the quarter, partly offset by the share buyback, a lower effective tax rate and lower NCIs, as well as lower net finance expenses in Q2.

All values are in US Dollars.

Total cost of sales as a percentage of sales decreased in the quarter and YTD primarily driven by Core cost of sales benefits, partly offset by impairments in the quarter.

Total SG&A as a percentage of sales decreased in the quarter and YTD primarily due to Core SG&A benefits, partly offset in the YTD by amounts reclassified from the foreign currency translation reserve to the income statement upon the liquidation of a subsidiary, and acquisition and integration costs related to RAPT Therapeutics ("RAPT").

Total R&D growth in Q2 2026 and YTD was driven by higher impairments in the quarter for camlipixant (£1,334 million) and the termination of assets related to the collaboration with Alector (£371 million), related to the outcomes of clinical trials. See page 17 for more details. In addition there was an increase in Core R&D investment.

Total royalty income decreased in the quarter and YTD driven by Core royalties.

Other operating income/(expense) in Q2 2026 included a charge of £486 million (Q2 2025: £89 million credit) arising from the remeasurement of CCLs, partly offset by net income of £288 million (Q2 2025: £31 million) primarily related to the divestment of linerixibat. Other operating income/(expense) YTD included a charge of £751 million (YTD 2025: £87 million credit) principally arising from the remeasurement of CCLs, partly offset by net income of £708 million (YTD 2025: £22 million) primarily related to profit on the sale of the Rockville manufacturing facility to Samsung Biologics, and the divestment of linerixibat. See pages 17 and 19 for further details.

Net finance costs decreased in the quarter and increased in YTD mainly due to movements in Core net finance expenses.

The effective tax rate on Total results reflected the different tax effects of the various Adjusting items included in Total results. Issues related to taxation are described in Note 14, ‘Taxation’ in the Annual Report 2025. The Group continues to believe it has made adequate provision for the liabilities likely to arise from periods that are open and not yet agreed by relevant 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.

The decrease in Total NCIs in Q2 and YTD was primarily driven by remeasurement charges on the Shionogi-ViiV CCL compared to credits in prior periods, partly offset by higher core profit allocations from ViiV Healthcare.

Exchange rates and impact on results

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

Q2 2026 Q2<br>2025 H1 2026 H1<br>2025 2025
Average<br>rates:
US$/£ 1.34 1.34 1.34 1.30 1.31
Euro/£ 1.15 1.18 1.15 1.19 1.17
Yen/£ 213 194 212 193 198
Period-end<br>rates:
US$/£ 1.32 1.37 1.32 1.37 1.35
Euro/£ 1.16 1.17 1.16 1.17 1.15
Yen/£ 215 198 215 198 211

In Q2 2026 and YTD, the adverse currency impact primarily reflected the strengthening of Sterling against the US Dollar, particularly in Q1 2026, as well as the Yen and emerging market currencies, partly offset by strengthening of the Euro. Exchange losses on the settlement of intercompany transactions had an adverse impact of one percentage point on Total and Core EPS in the YTD, and minimal impact in the quarter.

Q2 2026

Cash generated from operations for the quarter was £2,906 million (Q2 2025: £2,433 million). The increase primarily reflected higher Core operating profit, favourable timing and movements on trade receivables and payables, partly offset by inventory build to support new product launches and adverse timing and movements on returns and rebates.

Total contingent consideration cash payments in the quarter were £378 million (Q2 2025: £333 million). £374 million (Q2 2025: £330 million) of these were recognised in cash flows from operating activities, including cash payments made to Shionogi & Co. Ltd ("Shionogi") of £348 million (Q2 2025: £319 million).

Free cash inflow was £1,994 million for the quarter (Q2 2025: £1,126 million). The increase was primarily driven by higher cash generated from operations, proceeds from the divestment of linerixibat and lower tax payments.

H1 2026

Cash generated from operating activities was £4,256 million (H1 2025: £3,734 million). The increase reflected higher Core operating profit, favourable timing and movements on trade receivables and the final cash settlement from CureVac, partly offset by exchange and adverse timing and movements on returns and rebates.

Total contingent consideration cash payments in H1 2026 were £757 million (H1 2025: £674 million). £749 million (H1 2025: £668 million) of these were recognised in cash flows from operating activities, including cash payments made to Shionogi & Co. Ltd of £710 million (H1 2025: £650 million).

Free cash inflow was £2,809 million for H1 2026 (H1 2025: £1,823 million). The increase was driven by higher cash generated from operations, higher proceeds from the sale of intangible assets, including the divestment of linerixibat, and the special dividend of $250 million (£187 million) related to the ViiV shareholding restructure.

Total Net debt

At 30 June 2026, net debt was £15,132 million, compared with £14,453 million at 31 December 2025, comprising gross debt of £18,238 million and cash and liquid investments of £3,106 million. See net debt information on page 34.

Net debt increased by £679 million primarily due to net acquisition costs of £2,083 million related to RAPT Therapeutics and 35Pharma Inc., dividends paid to shareholders of £1,370 million, shares purchased as part of the share buyback programme (completed in June 2026) of £634 million and an exchange loss on net debt of £76 million. This was partly offset by primarily the free cash inflow of £2,809 million and £398 million related to the disposal of the Rockville site including proceeds and a reduction in lease liabilities.

At 30 June 2026, GSK had short-term borrowings (including overdrafts and lease liabilities) repayable within 12 months of £4,291 million and £2,058 million repayable in the subsequent year.

Progress on areas for responsible business

Being a responsible business is a fundamental part of GSK’s strategy and supports long-term performance. Annual progress against GSK’s responsible business priorities is detailed in the Annual(1) and Responsible Business(2) Reports with incremental updates shared each quarter. Highlights below include activity since Q1 2026 results.

Access

In<br>April, GSK and Medicines for Malaria Venture (MMV) announced(3) the world’s<br>first rollout of paediatric tafenoquine in Brazil - followed by<br>Thailand in May - providing children with relapsing P. Vivax malaria access to this single<br>dose treatment to help prevent relapse and support elimination<br>efforts.

Global health and health security

Malaria<br>remains one of the leading causes of death among children under<br>five in sub-Saharan Africa. In May, results published(4) in The Lancet from the World Health<br>Organization’s Malaria Vaccine Implementation Programme<br>(MVIP), provided real-world evidence that the RTS,S malaria<br>vaccine, developed by GSK, helped reduce child mortality over a<br>period of four years in Ghana, Kenya and Malawi, with an estimated<br>one in eight deaths averted among eligible children.
In<br>July, the GSK-developed novel M72/AS01E tuberculosis vaccine<br>candidate (licensed to Gates Medical Research Institute in 2020)<br>progressed(5) toward global<br>access with a new manufacturing agreement between the Gates MRI and<br>Serum Institute of India, pending successful Phase III trial<br>outcomes. The agreement also commits GSK, as the adjuvant<br>innovator, to a manufacturing partner for M72/ AS01E, and marks a<br>critical step toward ensuring that, if approved, the vaccine can be<br>produced at scale and made available to those who need it<br>most.

Environment

In May,<br>GSK was named a Supplier Engagement<br>Leader by the CDP(6), in addition to<br>maintaining A-list status for Climate Change and Water Security.<br>This recognises GSK’s work with suppliers to decarbonise its<br>value chain beyond its own operations, which protects supply chain<br>resilience and long-term ability to deliver medicines and<br>vaccines.

Total and Core results

Total reported results represent the Group’s overall performance.

GSK uses a number of non-IFRS measures to report the performance of its business. Core results and other non-IFRS measures may be considered in addition to, but not as a substitute for, or superior to, information presented in accordance with IFRS. Core results are defined below and other non-IFRS measures are defined on pages 50 and 51.

GSK believes that Core results, when considered together with Total results, provide investors, analysts and other stakeholders with helpful complementary information to understand better the financial performance and position of the Group from period to period, and allow the Group’s performance to be more easily compared against the majority of its peer companies. These measures are also used by management for planning and reporting purposes. They may not be directly comparable with similarly described measures used by other companies.

GSK encourages investors and analysts not to rely on any single financial measure but to review GSK’s quarterly results announcements, including the financial statements and notes, in their entirety.

GSK is committed to continuously improving its financial reporting, in line with evolving regulatory requirements and best practice. In line with this practice, GSK expects to continue to review and refine its reporting framework.

Core results exclude the following items in relation to our operations from Total results, together with the tax effects of all of these items:

amortisation<br>of intangible assets (excluding computer software and capitalised<br>development costs) to reflect the Group's performance excluding the<br>effect of acquisitions
impairment<br>of intangible assets (excluding computer software) and goodwill to<br>reflect the Group's performance excluding the effect of<br>acquisitions
major<br>restructuring and integration costs, which are:
cash<br>and non-cash costs such as impairment of tangible assets and<br>computer software of Major restructuring programmes, which are<br>specific Board-approved programmes that are structural and of<br>significant scale, where the costs of individual or related<br>projects within such programmes exceed £25 million;<br>or
costs<br>that relate to restructuring and integration following a<br>significant acquisition.
Costs<br>for other ordinary course, smaller-scale restructuring and<br>integration are retained within both Total and Core<br>results
transaction-related<br>accounting or other adjustments related to significant<br>acquisitions
proceeds<br>and costs of disposal of associates, products and businesses;<br>significant settlement income; Significant legal charges (net of<br>insurance recoveries) and expenses on the settlement of litigation<br>and government investigations; other operating income other than<br>royalty income, and other items including amounts reclassified from<br>the foreign currency translation reserve to the income statement<br>upon the liquidation of a subsidiary where the amount exceeds<br>25 million

All values are in British Pounds.

As Core results include the benefits of Major restructuring programmes but exclude significant costs (such as Significant legal charges and expenses, major restructuring costs and transaction items) they should not be regarded as a complete picture of the Group’s financial performance, which is presented in Total results. The exclusion of other Adjusting items may result in Core earnings being materially higher or lower than Total earnings. In particular, when significant impairments, restructuring charges and legal costs are excluded, Core earnings will be higher than Total earnings.

GSK has undertaken a number of Major restructuring programmes in response to significant changes in the Group’s trading environment or overall strategy or following material acquisitions. Within the Pharmaceuticals sector, the highly regulated manufacturing operations and supply chains and long lifecycle of the business mean that restructuring programmes, particularly those that involve the rationalisation or closure of manufacturing or R&D sites are likely to take several years to complete. Costs, both cash and non-cash, of these programmes are provided for as individual elements are approved and meet the accounting recognition criteria. As a result, charges may be incurred over a number of years following the initiation of a Major restructuring programme.

Significant legal charges and expenses are those arising from the settlement of litigation or government investigations that are not in the normal course and materially larger than more regularly occurring individual matters. They also include certain major legacy matters.

Reconciliations between Total and Core results, providing further information on the key Adjusting items, are set out on pages 16 and 18.

GSK provides earnings guidance to the investor community on the basis of Core results. This is in line with peer companies and expectations of the investor community, supporting easier comparison of the Group’s performance with its peers. GSK is not able to give guidance for Total results as it cannot reliably forecast certain material elements of the Total results, particularly the future fair value movements on contingent consideration and put options that can and have given rise to significant adjustments driven by external factors such as currency and other movements in capital markets.

ViiV Healthcare

ViiV Healthcare is a subsidiary of the Group and 100% of its operating results (turnover, operating profit, profit after tax) are included within the Group income statement.

On 19 January 2026, GSK reached agreement with Pfizer and Shionogi for the 11.7% economic interest in ViiV Healthcare held by Pfizer to be replaced with an investment by Shionogi. On 31 March 2026, the transaction completed and Shionogi increased its economic interest to 21.7% and GSK maintained its 78.3% economic interest. ViiV Healthcare issued new shares to Shionogi for consideration of $2.125 billion, and cancelled Pfizer’s holding in ViiV Healthcare, returning $1.875 billion to Pfizer. GSK received a special dividend of $0.250 billion (£187 million). Further, on completion GSK extinguished the Pfizer put option liability through retained earnings. The put option liability was £822 million as at 31 December 2025 and was remeasured immediately prior to completion, on the same methodology as at 31 December 2025, with the £33 million change in the liability recognised as an Adjusting item through other operating income/(expense).

Earnings for the year are allocated to the two shareholders of ViiV Healthcare on the basis of their respective equity shareholdings (GSK 78.3% and Shionogi 21.7%) and their entitlement to preferential dividends, which are determined by the performance of certain products attributable to each shareholder. As the relative performance of these products changes over time, the proportion of the overall earnings allocated to each shareholder also changes. In particular, the increasing proportion of sales of dolutegravir and cabotegravir-containing products has a favourable impact on the proportion of the preferential dividends that is allocated to GSK. Adjusting items are allocated to shareholders based on their equity interests. GSK was entitled to approximately 83% of the Total earnings and 83% of the Core earnings of ViiV Healthcare for 2025.

As consideration for the acquisition of Shionogi’s interest in the former Shionogi-ViiV Healthcare joint venture in 2012, Shionogi received the 10% equity stake in ViiV Healthcare and ViiV Healthcare also agreed to pay additional future cash consideration to Shionogi, contingent on the future sales performance of the products being developed by that joint venture, dolutegravir and cabotegravir. Under IFRS 3 ‘Business combinations’, GSK was required to provide for the estimated fair value of this contingent consideration at the time of acquisition and is required to update the liability to the latest estimate of fair value at each subsequent period end. The liability for the contingent consideration recognised in the balance sheet at the date of acquisition was £659 million. Subsequent remeasurements are reflected within other operating income/(expense) and within Adjusting items in the income statement in each period.

Cash payments to settle the contingent consideration are made to Shionogi by ViiV Healthcare each quarter, based on the actual sales performance and other income of the relevant products in the previous quarter. These payments reduce the balance sheet liability and hence are not recorded in the income statement. The cash payments made to Shionogi by ViiV Healthcare in the six months ended 30 June 2026 were £710 million.

As the liability is required to be recorded at the fair value of estimated future payments, there is a significant timing difference between the charges that are recorded in the Total income statement to reflect movements in the fair value of the liability and the actual cash payments made to settle the liability.

Further explanation of the acquisition-related arrangements with ViiV Healthcare are set out on pages 86 and 87 of the Annual Report 2025.

Adjusting items Q2 2026

Intangible asset impairments

Impairments of £1,895 million (Q2 2025: £476 million) were incurred primarily relating to camlipixant (£1,334 million) following GSK's decision not to progress further development of camlipixant in RCC, based on the aggregate data from the CALM-1 and CALM-2 phase III trials. The recoverable amount of camlipixant, based on value in use for the IBS indication is £104 million, which is the carrying value as at 30 June 2026.

In addition, a full impairment of £371 million was recognised following the termination of assets under the Alector collaboration, driven by the outcome of clinical trials.

Major restructuring and integration

Charges of £23 million (Q2 2025: £13 million) were incurred relating to ongoing projects categorised as Major restructuring programmes and integration costs, analysed as follows:

Q2 2026 Q2<br>2025
Cash<br><br><br>£m Non-<br><br><br>cash<br><br><br>£m Total<br><br><br>£m Cash<br><br><br>£m Non-<br><br><br>cash<br><br><br>£m Total<br><br><br>£m
Significant<br>acquisitions 22 22 7 7
Legacy<br>programmes 1 1 3 3 6
22 1 23 10 3 13

Integration costs of significant acquisitions relate predominantly to integration activities for RAPT acquired in Q1 2026, with smaller incremental costs attributed to earlier acquisitions - Affinivax Inc. (Affinivax) in Q3 2022, BELLUS Health Inc. (Bellus) in Q2 2023, and BP Asset IX in Q3 2025.

Transaction-related adjustments

Transaction-related adjustments resulted in a net charge of £491 million (Q2 2025: £88 million credit), the majority of which related to charges/(credits) for the remeasurement of contingent consideration liabilities.

Charge/(credit) Q2 2026<br><br><br>£m Q2<br>2025<br><br><br>£m
Contingent<br>consideration on former Shionogi-ViiV Healthcare joint venture<br>(including Shionogi preferential dividends) 392 (127)

Other<br>contingent consideration 74 3
Other<br>adjustments 5 1
Total<br>transaction-related charges/(credits) 491 (88)

The £392 million charge relating to the contingent consideration for the former Shionogi-ViiV Healthcare joint venture represented an increase in the valuation of the contingent consideration due to Shionogi driven by updated sales forecasts and net other remeasurements of £301 million and the unwind of the discount for £91 million.

Divestments, Significant legal charges, and other items

Divestments, Significant legal charges, and other items included net other operating income of £288 million (Q2 2025: £32 million) primarily related to proceeds from the divestment of linerixibat.

Legal charges provide for all significant legal matters and are not broken out separately by litigation or investigation.

Adjusting items H1 2026

Intangible asset impairments

Impairments of £2,067 million (H1 2025: £540 million) were incurred primarily relating to camlipixant £1,334 million in Q2 2026 following GSK's decision not to progress further development of camlipixant in RCC, based on the aggregate data from the CALM-1 and CALM-2 phase III trials.

In addition, a full impairment of £371 million was recognised in Q2 2026 following the termination of assets under the Alector collaboration, driven by the outcome of clinical trials.

Major restructuring and integration

Charges of £47 million (H1 2025: £33 million) were incurred relating to ongoing projects categorised as Major restructuring programmes, analysed as follows:

H1 2026 H1<br>2025
Cash<br><br><br>£m Non-<br><br><br>cash<br><br><br>£m Total<br><br><br>£m Cash<br><br><br>£m Non-<br><br><br>cash<br><br><br>£m Total<br><br><br>£m

46 1 47 18 15 33

The Significant acquisitions programme incurred cash charges of £44 million primarily from integration activities for RAPT acquired in Q1 2026, with smaller incremental costs attributed to earlier acquisitions - Affinivax Inc. (Affinivax) in Q3 2022, BELLUS Health Inc. (Bellus) in Q2 2023, and BP Asset IX in Q3 2025.

Transaction-related adjustments

Transaction-related adjustments resulted in a net charge of £770 million (H1 2025: £78 million net credit), the majority of which related to charges/(credits) for the remeasurement of contingent consideration liabilities.

Charge/(credit) H1 2026<br><br><br>£m H1<br>2025<br><br><br>£m
Contingent<br>consideration on former Shionogi-ViiV Healthcare joint venture<br>(including Shionogi preferential dividends) 680 (88)

Other<br>contingent consideration 97 7
Other<br>adjustments 19 9
Total<br>transaction-related charges 770 (78)

The £680 million charge relating to the contingent consideration for the former Shionogi-ViiV Healthcare joint venture represented an increase in the valuation of the contingent consideration due to Shionogi, driven by updated sales forecasts and net other remeasurements of £487 million and the unwind of the discount for £193 million.

The £33 million credit on the ViiV put option and Pfizer preferential dividend relates to the remeasurement of the put option with Pfizer. The agreement with Pfizer and Shionogi for the 11.7% economic interest in ViiV Healthcare held by Pfizer was replaced with an investment by Shionogi completed on 31 March 2026 and as a result GSK extinguished the Pfizer put option liability through retained earnings. An explanation of the accounting for the non-controlling interests in ViiV Healthcare is set out on page 15.

Significant legal charges, Divestments, and other items

Divestments, Significant legal charges, and other items included net other operating income of £708 million (YTD 2025: £23 million) primarily related to profit on the sale of the Rockville manufacturing facility, including £375m reclassified from the foreign currency translation reserve to the income statement on disposal of the related subsidiary, and proceeds from the divestment of linerixibat. This was partly offset by amounts reclassified from the foreign currency translation reserve to the income statement upon the liquidation of subsidiaries.

Legal charges provide for all significant legal matters and are not broken out separately by litigation or investigation.

Core operating profit growth in Q2 2026 and H1 2026 primarily reflected higher turnover, favourable product and regional mix, and favourable net legal settlements and expenses in Q1 2026, partly offset by increased investment in asset launches, as well as lower royalty income in Q2 2026.

Total R&D

The Total R&D segment operating expense increased in Q2 2026 and H1 2026 reflecting progression across the portfolio. In Oncology, this included acceleration in work on ADCs Ris-Rez and Mo-Rez, and velzatinib. In Specialty Medicines, increased investment was driven by efimosfermin acquired in Q3 2025, depemokimab COPD indication and all indications of the anti-TSLP monoclonal antibody. Growth was partly offset by lower spend on bepirovirsen which was filed in Q1 2026. Investment also increased on clinical trial programmes associated with mRNA seasonal flu vaccines.

Legal matters

The Group is involved in significant legal and administrative proceedings, principally product liability, intellectual property, tax, anti-trust, consumer fraud and governmental investigations, which are more fully described in the ‘Legal Proceedings’ note in the Annual Report 2025. At 30 June 2026, the Group’s aggregate provision for legal and other disputes (not including tax matters described on pages 7 and 8) was £232 million (31 December 2025: £210 million).

The Group may become involved in significant legal proceedings in respect of which it is not possible to meaningfully assess whether the outcome will result in a probable outflow, or to quantify or reliably estimate the liability, if any, that could result from ultimate resolution of the proceedings. In these cases, the Group would provide appropriate disclosures about such cases, but no provision would be made.

The ultimate liability for legal claims may vary from the amounts provided and is dependent upon the outcome of litigation proceedings, investigations and possible settlement negotiations. The Group’s position could change over time, and, therefore, there can be no assurance that any losses that result from the outcome of any legal proceedings will not exceed by a material amount the amount of the provisions reported in the Group’s financial accounts.

Significant legal developments since the date of the Q1 2026 results:

Product Liability

Avandia

On 21 July 2026, the Third Circuit Court of Appeals vacated the district court’s decision certifying a class. The Third Circuit set forth the legal and evidentiary requirements that the third-party payor plaintiffs are required to satisfy for their claims to proceed as a class action and remanded the case to the district court for further proceedings consistent with the decision.

Zantac

On 13 April 2026, the Delaware Superior Court issued its decision granting summary judgment as to all remaining cases filed on or before 1 December 2025, as Plaintiffs have not demonstrated general causation, which is a required element of each of Plaintiffs’ cases. On 13 May 2026, Plaintiffs filed a notice of appeal of the summary judgment order. This appeal would apply to the six GSK cases that were pending at the time of the summary judgment decision.

As previously disclosed, approximately 14,000 product liability cases were dismissed following the grant of defendants’ Daubert motions in December 2022 in the Federal MDL proceeding. These are now on appeal by the plaintiffs to the United States Court of Appeals for the Eleventh Circuit, along with appeals in the medical monitoring and consumer class action cases. Oral argument was held on 10 October 2025. A decision is expected in H2 2026.

Commercial and corporate

Tesaro, Inc. v. AnaptysBio

The trial was held before the Delaware Chancery Court on 14-17 July 2026. The Court has requested the parties submit post-trial briefs in advance of a post-trial hearing which has been scheduled for 20 October 2026. A decision is expected in Q4 2026 or Q1 2027.

Zejula Royalty Dispute

In October 2012, Tesaro, Inc. (now a wholly owned subsidiary of GSK) entered into two worldwide patent license agreements with AstraZeneca UK Limited related to niraparib (later approved as Zejula). In May 2021, AstraZeneca filed a lawsuit against Tesaro in the High Court, England and Wales alleging that Tesaro failed to pay some of the royalties due under the license agreements. Tesaro filed a counterclaim based on a calculated overpayment. Trial was held the week of 6 March 2023 and judgment was entered against the Group on 5 April 2023. On 9 February 2024 the Court of Appeal ruled in the Group’s favour, overturning the trial court’s judgment and determining that only Zejula sales for uses falling within the licensed patents could be deemed royalty-bearing. AstraZeneca requested permission to appeal and on 28 May 2024, the UK Supreme Court rejected AstraZeneca’s request. Further proceedings would have determined the correct quantum of royalties in light of the Court of Appeal’s ruling. In July 2026, the parties agreed to a settlement. This matter has concluded.

Intellectual Property

Trelegy Ellipta

On 22 January 2026, GSK received a paragraph IV letter from Transpire relating to Trelegy Ellipta 100 mcg. On 6 March 2026, GSK filed suit in the U.S. District Court for the Southern District of Florida asserting infringement of the five Orange Book listed patents by Transpire’s proposed generic version of Trelegy Ellipta 100 mcg. A trial has been set for 22 February 2028.

On 7 May 2026, Transpire sent GSK a second Paragraph IV notice letter indicating that it had filed an ANDA seeking approval from the FDA to market a generic version of Trelegy Ellipta 200 mcg. On 16 June 2026, GSK filed suit in the U.S. District Court for the Southern District of Florida asserting infringement of the four Orange Book-listed patents by Transpire’s proposed generic version of Trelegy Ellipta 200 mcg. A case schedule has not yet been set.

Returns to shareholders

Quarterly dividends

The Board has declared a second interim dividend for Q2 2026 of 17p per share (Q2 2025: 16p per share).

Dividends remain an essential component of total shareholder return and GSK recognises the importance of dividends to shareholders. On 23 June 2021, at the GSK Investor Update, GSK set out that from 2022 a progressive dividend policy will be implemented guided by a 40 to 60 per cent pay-out ratio through the investment cycle. Consistent with this, GSK has declared a dividend of 17p per share for Q2 2026. The expected dividend for 2026 is 70p per share. In setting its dividend policy, GSK considers the capital allocation priorities of the Group and its investment strategy for growth alongside the sustainability of the dividend.

Share capital in issue

At 30 June 2026, 4,007 million shares (Q2 2025: 4,047 million) were in free issue (excluding Treasury shares and shares held by the ESOP Trusts). The Company issued 0.1 million shares in the quarter (Q2 2025: 0.2 million) under employee share schemes for net proceeds of £1 million (Q2 2025: £2 million).

On 5 February 2025, GSK announced a £2 billion share buyback programme to be completed over an 18 month period. This share buyback programme was completed on 26 June 2026, with a total of 124 million shares repurchased and being held as Treasury shares, at a cost of £2,011 million including transaction costs of £11 million.

The cost of shares repurchased in Q2 2026 was £294 million (Q2 2025: £549 million) including transaction costs of £1 million (Q2 2025: £4 million).

At 30 June 2026, the Company held 271 million Treasury shares at a cost of £4,580 million, of which 147 million shares at a cost of £2,571 million were repurchased as part of previous share buyback programmes, which has been deducted from retained earnings.

At 30 June 2026, the ESOP Trusts held 38.4 million shares, of which 37.8 million were held for the future exercise of share options and share awards and 0.6 million were held for the Executive Supplemental Savings plan. The carrying amount of £168 million has been deducted from other reserves. The market value of these shares was £761 million.

Additional information

Accounting policies and basis of preparation

This unaudited Results Announcement contains condensed financial information for the three and six months ended 30 June 2026 and should be read in conjunction with the Annual Report 2025, which was prepared in accordance with UK-adopted international accounting standards in conformity with the requirements of the Companies Act 2006 and the IFRS Accounting Standards as issued by the International Accounting Standards Board (IASB). This Results Announcement has been prepared in accordance with IAS 34 and applying consistent accounting policies to those applied by the Group in the Annual Report 2025, except for the adoption of the amendments to IFRS 9 and IFRS 7 as set out below. Other minor amendments to IFRS Accounting Standards which were effective from 1 January 2026 did not have a material impact on the Group accounting policies or Group financial statements.

Amendments to the Classification and Measurement of Financial Instruments - Amendments to IFRS 9 and IFRS 7: the amendments to IFRS 9 ‘Financial Instruments’, clarify the timing of recognition and derecognition of a financial asset or financial liability, with a permitted exception relating to a financial liability paid through an electronic payment system which may be derecognised prior to its settlement date where specific conditions are met. GSK has adopted these new requirements for the reporting period beginning on 1 January 2026 and elected to derecognise financial liabilities paid through an electronic payment system when the required conditions have been met. The impact on the Group’s financial statements on transition as at 1 January 2026 is disclosed below and primarily relates to cheques which were issued but had not yet cleared from the bank account before the transition date. As permitted under the transition requirements, the Group has elected not to restate the comparative information to reflect the application of these amendments.

As at<br><br><br>1 January 2026<br><br><br>£m Adjustment on initial application of amendments to<br><br><br>IFRS 9 and IFRS 7<br><br><br>£m As at<br><br><br>1 January 2026<br><br><br>as adjusted<br><br><br>£m

Cash<br>and cash equivalents 3,397 14 3,411

The Group has not identified any changes to its key sources of accounting judgements or estimations of uncertainty compared with those disclosed in the Annual Report 2025.

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 2025 were published in the Annual Report 2025, which has been delivered to the Registrar of Companies and on which the report of the independent auditor was unqualified and did not contain a statement under section 498 of the Companies Act 2006.

Contingent liabilities

There were contingent liabilities at 30 June 2026 in respect of arrangements entered into as part of the ordinary course of the Group’s business. No material losses are expected to arise from such contingent liabilities. Provision is made for the outcome of legal and tax disputes where it is both probable that the Group will suffer an outflow of funds and it is possible to make a reliable estimate of that outflow. Descriptions of the significant legal disputes to which the Group is a party are set out on page 29, and pages 269 to 272 of the 2025 Annual Report.

Net assets

The book value of net assets increased by £1,221 million from £15,956 million at 31 December 2025 to £17,177 million at 30 June 2026. This primarily reflected contribution from Total comprehensive income for the period and the special dividend from the ViiV Healthcare shareholding restructure, partly offset by dividends paid to shareholders, shares repurchased under the share buyback programme and associated transaction costs.

At 30 June 2026, the net surplus on the Group’s pension plans was £563 million compared with a net surplus of £229 million at 31 December 2025. This movement was primarily driven by an increase in the UK discount rate from 5.5% to 6.0%, which was partially offset by an increase to the UK inflation rate from 2.7% to 2.8%.

The estimated present value of the potential redemption amount of the Pfizer put option related to ViiV Healthcare, recorded in Other payables in Current liabilities, was £nil (31 December 2025: £822 million). The put option liability was fully derecognised at 31 March 2026 as Pfizer has exited its shareholding in ViiV Healthcare.

Contingent consideration amounted to £6,781 million at 30 June 2026 (31 December 2025: £6,733 million) as follows:

Group<br><br><br>30 June 2026<br><br><br>£m Group<br><br><br>31<br>December 2025<br><br><br>£m

Of the contingent consideration payable to Shionogi at 30 June 2026, £1,232 million (31 December 2025: £1,194 million) is expected to be paid within one year.

Business acquisitions

On 3 March 2026, GSK completed the acquisition of 100% of the outstanding equity of RAPT Therapeutics, Inc. ("RAPT") a California-based clinical stage biopharmaceutical company dedicated to developing novel therapies for patients living with inflammatory and immunologic diseases. The acquisition includes ozureprubart, a long-acting anti-immunoglobulin E (IgE) monoclonal antibody, currently in phase IIb clinical development for prophylactic protection against food allergens.

Under the terms of the agreement, GSK paid RAPT shareholders US$58.00 per share at closing, for an aggregate payment of US$2.3 billion (£1.7 billion), including transaction fees. Net of cash acquired, GSK's upfront investment was approximately US$1.9 billion (£1.4 billion).

The transaction gives GSK the global rights to the ozureprubart programme, excluding mainland China, Macau, Taiwan and Hong Kong. GSK will also be responsible for success-based milestone and royalty payments for ozureprubart owed to RAPT's partner, Shanghai Jeyou Pharmaceutical Co., Ltd.

On 14 April 2026, GSK completed the acquisition of 100% of 35Pharma, Inc. ("35Pharma") a Canada-based, private, clinical-stage biopharmaceutical company specialised in the development of novel protein-based therapeutics. The acquisition provides global rights to HS235, a potential best-in-class activin signalling inhibitor being developed for the treatment of pulmonary hypertension.

Total consideration was US$1.0 billion (£755 million), comprising an upfront payment of US$987 million (£730 million) as adjusted for working capital and other customary closing adjustments and US$34 million (£25 million) of deferred consideration. Net of cash acquired, GSK's net cash investment was US$944 million (£699 million).

During the period to 30 June 2026, no sales arising from the RAPT or 35Pharma's businesses were included in Group turnover and no revenue is expected until regulatory approval is received on the acquired assets.

GSK continues to support the ongoing development of the acquired assets and consequently these assets will be loss making until regulatory approval on these assets is received. The impact on Total profit after taxation for the period ended 30 June 2026 from these acquisitions was immaterial. The development of these assets will be integrated into the Group’s existing R&D activities, after which it will be impracticable to quantify these development costs or the impact on Total profit after taxation.

The initial acquisition accounting was reflected in the second quarter of 2026 on a preliminary basis, the values below are provisional and subject to change. The purchase price allocation is expected to be completed by the end of Q4 2026.

Goodwill of £311 million (£211 million for RAPT and £100 million for 35Pharma) has been recognised. The goodwill represents specific synergies available to GSK from the business combination. The goodwill has been allocated to the Group’s Commercial Operations and R&D segments. None of the goodwill is expected to be deductible for tax purposes.

The provisional fair values of the net assets acquired, including goodwill, are as follows:

RAPT 35Pharma Total
£m £m £m
Net<br>assets acquired:
Intangible<br>assets 1,457 703 2,160

1,474 655 2,129
Goodwill 211 100 311
Total<br>consideration 1,685 755 2,440

Of the total £2.4 billion consideration (£1.7 billion for RAPT and £0.7 billion for 35Pharma), £20 million of deferred consideration for 35Pharma was unpaid as at 30 June 2026.

Post balance sheet events

On 9 June 2026, GSK entered into an agreement to acquire Nuvalent, Inc. ("Nuvalent"), a Boston-based clinical-stage biopharmaceutical company focused on creating precisely targeted oncology therapies. Nuvalent’s lead assets, zidesamtinib and neladalkib, are late-stage, potential best-in-class ROS1 and ALK inhibitors for treatment of non-small cell lung cancer (NSCLC). In July 2026, the US FDA approved zidesamtinib for the treatment of adult patients with locally advanced or metastatic ROS1-positive NSCLC who received a prior ROS1 kinase inhibitor. Neladalkib is currently under FDA review.

Under the agreement, GSK acquired Nuvalent for $124.00 per share in cash, representing an aggregate equity value of approximately $10.6 billion (£8.0 billion). Net of cash acquired, GSK’s aggregate investment is approximately $9.4 billion (£7.1 billion), which is funded primarily from new and existing debt facilities plus cash.

The transaction was subject to customary conditions, including the tender of the majority of Nuvalent’s outstanding shares of Class A common stock and applicable regulatory agency clearances under the Hart-Scott-Rodino Act in the US, and subsequently closed on 15 July 2026. Given the timing of the closure of the transaction, GSK expects to disclose the provisional accounting for the acquisition in the Q3 2026 Results Announcement.

Financial instruments fair value disclosures

The following tables categorise the Group’s financial assets and liabilities held at fair value by the valuation methodology applied in determining their fair value. Where possible, quoted prices in active markets are used and the asset or liability is classified as Level 1. Where such prices are not available, the asset or liability is classified as Level 2, provided all significant inputs to the valuation model used are based on observable market data. If one or more of the significant inputs to the valuation model is not based on observable market data, the instrument is classified as Level 3. Other investments classified as Level 3 in the tables below comprise equity investments in unlisted entities with which the Group has entered into research collaborations and also investments in emerging life science companies.

BP<br>Asset IX 9.5% 9.0%
Affinivax 9.5% 9.0%

Contingent consideration is expected to be paid over a number of years and will vary in line with the future performance of specified products, the achievement of certain milestone targets and movements in certain foreign currencies.

The financial liabilities are measured at the present value of expected future cash flows, the most significant inputs and assumptions in the valuation models being future sales forecasts, probability of milestone success, the discount rate, the Sterling/US Dollar exchange rate and the Sterling/Euro exchange rate. The exchange rates used are consistent with market rates at 30 June 2026.

The Shionogi-ViiV Healthcare and Novartis Vaccines contingent consideration liabilities are calculated principally based on the forecast sales performance of specified products over the lives of those products.

The BP Asset IX contingent consideration is based upon three milestone payments, totalling $0.8 billion (£0.6 billion), which will be paid if certain clinical development and regulatory milestones are achieved.

The Affinivax contingent consideration is based upon two potential milestone payments, each of $0.6 billion (£0.5 billion) which will be paid if certain paediatric clinical development milestones are achieved.

The table below shows, on an indicative basis, the income statement and balance sheet sensitivity to reasonably possible changes in key inputs to the valuation of the largest contingent consideration liabilities.

The Group transfers financial instruments between different levels in the fair value hierarchy when, as a result of an event or change in circumstances, the valuation methodology applied in determining their fair values alters in such a way that it meets the definition of a different level. There were no transfers between the Level 1, Level 2 or Level 3 fair value measurement categories.

The following methods and assumptions are used to measure the fair value of the significant financial instruments carried at fair value on the balance sheet:

Other<br>investments – equity investments traded in an active market<br>determined by reference to the relevant stock exchange quoted bid<br>price; other equity investments determined by reference to the<br>current market value of similar instruments, recent financing<br>rounds or the discounted cash flows of the underlying net<br>assets
Trade<br>receivables carried at fair value – based on invoiced<br>amount
Interest<br>rate swaps, foreign exchange forward contracts, swaps and options<br>– based on the present value of contractual cash flows or<br>option valuation models using market-sourced data (exchange rates<br>or interest rates) at the balance sheet date
Cash<br>and cash equivalents carried at fair value – based on net<br>asset value of the funds
Contingent<br>consideration for business acquisitions and divestments –<br>based on present values of expected future cash flows

There are no material differences between the carrying amount of the Group's other financial assets and liabilities and their estimated fair value, with the exception of bonds, for which the carrying amount and fair value are set out in the table below:

30 June 2026 31<br>December 2025
Carrying<br><br><br>amount<br><br><br>£m Fair<br><br><br>value<br><br><br>£m Carrying<br><br><br>amount<br><br><br>£m Fair<br><br><br>value<br><br><br>£m
Bonds<br>in a designated hedging relationship (5,584) (5,446) (6,524) (6,388)
Other<br>bonds (9,075) (9,069) (8,973) (9,104)
(14,659) (14,515) (15,497) (15,492)

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:

Receivables<br>and payables carried at amortised cost - approximates to the<br>carrying amount
Liquid<br>investments - approximates to the carrying amount
Cash<br>and cash equivalents carried at amortised cost - approximates to<br>the carrying amount
Short-term<br>loans, overdrafts and commercial paper - approximates to the<br>carrying amount because of the short maturity of these<br>instruments
Long-term<br>loans - based on quoted market prices (a level 1 fair value<br>measurement) in the case of European and US Medium Term Notes;<br>approximates to the carrying amount in the case of other fixed rate<br>borrowings and floating rate bank loans

efimosfermin (FGF21 analog)

Efimosfermin (GSK6519754) is an investigational, once-monthly subcutaneous injection of a long-acting variant of FGF21, designed to regulate key metabolic pathways to decrease liver fat, ameliorate liver inflammation, and reverse liver fibrosis in patients with metabolic dysfunction-associated steatohepatitis (MASH).

Efimosfermin is in phase III development for moderate and advanced fibrosis (F2 to F3) caused by MASH. In July 2026, GSK also started the phase III NEBULA trials which will investigate efimosfermin in compensated cirrhosis (F4) caused by MASH.

Efimosfermin has received Breakthrough Therapy Designations from the US Food and Drug Administration (FDA) and China’s Center for Drug Evaluation (CDE), as well as Priority Medicines (PRIME) Designation from the European Medicines Agency (EMA) for the treatment of MASH. Breakthrough Designation is designed to expedite the development and review of medicines for serious conditions, where preliminary clinical evidence indicates potential for substantial improvement over available therapy. PRIME designation provides scientific and regulatory support for medicines that have the potential to address significant unmet medical need.

Exdensur (depemokimab; ultra-long-acting anti-IL5)

Exdensur (depemokimab) is the first and only ultra-long-acting biologic to address severe asthma and chronic rhinosinusitis with nasal polyps (CRSwNP). It is engineered to have an extended half-life and high binding affinity and potency for IL-5, enabling twice-yearly dosing.

Exdensur is approved for the treatment of severe asthma and CRSwNP in the EU, China, Japan and the UK, and for the treatment of severe asthma in the US.

Depemokimab is currently being evaluated in phase III trials for the treatment of other diseases with underlying type 2 inflammation, including OCEAN for eosinophilic granulomatosis with polyangiitis (EGPA) and DESTINY for hypereosinophilic syndrome (HES). GSK has also initiated the ENDURA-1, ENDURA-2 and VIGILANT phase III trials assessing the efficacy and safety of depemokimab as an add-on therapy in patients with uncontrolled moderate to severe COPD with type 2 inflammation.

At the 2026 American Thoracic Society (ATS) International Conference, GSK presented data showing sustained efficacy over two years in patients with severe asthma with type 2 inflammation, and results from a new patient preference study showing patients prefer twice-yearly dosing.

Blenrep (belantamab mafodotin)

In Q2, GSK presented data for Blenrep at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting and the 31st European Hematology Association (EHA) Congress. These included long-term results from the DREAMM-7 and DREAMM-8 phase III clinical trials showing durable benefit versus standards of care in patients with relapsed or refractory multiple myeloma. In newly diagnosed transplant-ineligible multiple myeloma, results from the DREAMM-9 study provided new evidence to support the Blenrep frontline dosing strategy in the DREAMM-10 trial.

GSK is continuing the DREAMM (DRiving Excellence in Approaches to Multiple Myeloma) clinical development programme to explore the full potential of belantamab mafodotin, including in earlier lines of treatment. This includes DREAMM-10, a phase III clinical trial in newly diagnosed transplant-ineligible patients, who represent over 70% of patients starting multiple myeloma therapy.

Jemperli (dostarlimab)

In June 2026, GSK presented new long-term analyses from the RUBY phase III trial at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting. This modelling data showed an estimated higher 'cure' rate (i.e., free of recurrence- and disease-related mortality risk) for Jemperli plus chemotherapy in patients with dMMR/MSI-H primary advanced or recurrent endometrial cancer compared to chemotherapy alone.

In July 2026, GSK announced interim positive headline results from the phase II registrational single arm AZUR-1 trial investigating Jemperli in people with stage II/III dMMR/MSI-H locally advanced rectal cancer. The trial met its primary objective, demonstrating a meaningful and sustained clinical complete response rate at 12 months (cCR12). Jemperli has received both Breakthrough Therapy and Fast Track designations from the US Food and Drug Administration (FDA) in this setting. GSK plans to share interim AZUR-1 data with global regulatory authorities. Detailed results will be presented at a future scientific congress.

Jemperli remains the foundation of GSK’s immuno-oncology-based research and development programme. It is the only approved immuno-oncology-based plus carboplatin-paclitaxel (CP) treatment regimen to demonstrate a statistically significant and clinically meaningful overall survival benefit vs. CP alone for the first-line treatment of adult patients with primary advanced or recurrent endometrial cancer irrespective of biomarker status. Ongoing pivotal trials include those in the AZUR programme (colon / rectal cancers), JADE (head and neck cancer), and DOMENICA (supported-collaborative study with ARCAGY-GINECO in endometrial cancer).

Risvutatug rezetecan (Ris-Rez)

GSK is advancing its B7-H3-targeted antibody-drug conjugate, risvutatug rezetecan (Ris-Rez) through the EMBOLD global development programme across a range of solid tumours, including certain types of lung, prostate and colorectal cancers.

In July 2026, GSK's licensor Hansoh Pharma announced that ARTEMIS-008, its pivotal phase III trial evaluating Ris-Rez patients in China with advanced or relapsed small-cell lung cancer (SCLC), met its primary endpoint of overall survival (OS), demonstrating statistically significant and clinically meaningful improvements vs. standard of care topotecan. These are the first positive phase III OS data reported for a B7-H3-targeted ADC in any tumour type. GSK holds exclusive global rights to develop Ris-Rez outside mainland China, Hong Kong, Macau and Taiwan. GSK's broad clinical development programme includes studies in lung cancer, prostate cancer and other solid tumours, including the global phase III EMBOLD SCLC-301 trial in relapsed extensive-stage small-cell lung cancer (ES-SCLC) with pivotal data expected next year. This year, GSK plans to initiate additional phase III studies in lung and prostate cancers.

Regulatory designations received for Ris-Rez to date include orphan drug designations from the US FDA and Japan's Ministry of Health, Labour and Welfare in SCLC and the EMA in pulmonary neuroendocrine carcinoma (a category of cancer that includes SCLC), Priority Medicines (PRIME) Designation from the EMA for relapsed or refractory ES-SCLC; and Breakthrough Therapy Designations for relapsed or refractory ES-SCLC and relapsed or refractory osteosarcoma from the US FDA. These designations reflect the potential of Ris-Rez to address significant unmet medical need across a range of cancers.

Mocertatug rezetecan (Mo-Rez)

GSK is advancing Mo-Rez, a B7-H4–targeting antibody-drug conjugate, through the global BEHOLD development programme across multiple gynaecological cancer indications, where significant unmet need remains. B7-H4 is an immune checkpoint that is widely expressed in ovarian and endometrial cancers, and is low in normal tissues, making it a promising target for clinical development.

In 2026, GSK plans to initiate five phase III pivotal trials across ovarian and endometrial cancers. Two of these studies are now underway and actively recruiting patients: BEHOLD-Ovarian01 in platinum-resistant ovarian cancer and BEHOLD-Endometrial01 in advanced or recurrent endometrial cancer.

Three additional phase III studies are expected to start later in 2026, evaluating Mo-Rez in platinum-sensitive ovarian cancer (BEHOLD-Ovarian02), in first-line maintenance ovarian cancer without homologous recombination deficiency (BEHOLD-Ovarian03), and in first line maintenance mismatch repair–proficient endometrial cancer (BEHOLD-Endometrial02).

In April 2026, GSK presented positive data for Mo-Rez from the global phase I BEHOLD-1 study at the Society of Gynecologic Oncology (SGO) Annual Meeting on Women’s Cancer. Mo-Rez demonstrated compelling efficacy in platinum-resistant ovarian cancer and in recurrent or advanced endometrial cancer. The response to Mo-Rez observed across a range of B7-H4 expression levels reinforces its broad potential in gynaecologic cancers and further validates the relevance of targeting B7-H4.

Jideytro (zidesamtinib)

Jideytro (zidesamtinib) is a ROS1 tyrosine kinase inhibitor (TKI) designed to address key efficacy and tolerability challenges of treating ROS1-positive non-small cell lung cancer (NSCLC). Its next-generation design aims to combine high target-selectivity, broad coverage of ROS1 resistance mutations and blood-brain barrier penetration to address disease in the brain.

In July 2026, the US FDA approved zidesamtinib for the treatment of adult patients with locally advanced or metastatic ROS1-positive non-small cell lung cancer (NSCLC) who received a prior ROS1 kinase inhibitor. The FDA approval is based on results from the ARROS-1 (NCT05118789) global phase I/II trial evaluating zidesamtinib in patients with advanced ROS1 positive NSCLC and other ROS1-positive solid tumours.

Zidesamtinib continues to be studied in ARROS-1, including in first-line treatment for patients who have not previously received a ROS1 inhibitor. Zidesamtinib is GSK's first approved medicine in lung cancer and was added to the portfolio through the acquisition of Nuvalent.

neladalkib:

Neladalkib is an investigational ALK tyrosine kinase inhibitor (TKI) currently under review with the US FDA for use by patients with TKI pre-treated ALK-positive NSCLC, with PDUFA date anticipated in November 2026.

Neladalkib was previously granted US Breakthrough Therapy designation for the treatment of patients with locally advanced or metastatic ALK-positive NSCLC who have been previously treated with 2 or more ALK TKIs and Orphan Drug designation for ALK-positive NSCLC.

Neladalkib was designed to maintain activity against a broad range of ALK resistance mutations, while minimising off-target activity and optimising penetration into the central nervous system (CNS). The development programme is intended to address key challenges in the treatment of ALK-positive NSCLC, including acquired resistance and brain metastases.

The phase I/II ALKOVE-1 study is ongoing in patients with advanced ALK-positive NSCLC and other solid tumours, and the phase III ALKAZAR trial is evaluating neladalkib versus alectinib in first-line ALK-positive NSCLC.

Infectious Diseases

Arexvy (respiratory syncytial virus vaccine, adjuvanted)

GSK continues to progress the life-cycle innovation of Arexvy, its Respiratory Syncytial Virus (RSV) vaccine for adults, with expanded indications in new populations and geographies.

The vaccine is approved for the prevention of lower respiratory tract disease (LRTD) caused by RSV in adults aged 60 years of age and older in over 70 countries. It is also approved for use in adults aged 50–59 at increased risk (AIR) for LRTD caused by RSV due to certain underlying medical conditions in over 60 countries, including the US and Japan. In the US, it is approved for use in adults aged 18–49 years AIR and in the European Economic Area for adults aged 18 years and older. Arexvy is not for use in pregnant individuals.

In May, the Japanese Ministry of Health, Labour and Welfare (MHLW) expanded the eligible population for Arexvy to include adults aged 18 to 49 years AIR for RSV disease. The prescribing information for Arexvy in Japan was also updated to explicitly include immuno-compromised (IC) patients as an increased risk group. Arexvy is approved for use in IC adults aged 18 years and older in the European Economic Area and US FDA review in this population is ongoing with a decision expected this year.

China’s Center for Drug Evaluation (CDE) is reviewing a regulatory application for Arexvy for the prevention of LRTD caused by RSV in adults aged 60 years and older. A decision is expected in 2027.

bepirovirsen (HBV ASO)

Bepirovirsen is a triple-action antisense oligonucleotide with the potential to be a first in class new treatment option for people with chronic hepatitis B (CHB). It is designed to inhibit the replication of viral DNA in the body, suppress the level of hepatitis B surface antigen (HBsAg) in the blood, and stimulate the immune system to increase the chances of a durable and sustained response.

In May 2026, GSK presented positive results from its two pivotal phase III trials, B-Well 1 and B-Well 2, at the European Association for the Study of the Liver (EASL) conference, with simultaneous publication in the New England Journal of Medicine. Pooled data from both trials showed that 6-month treatment with bepirovirsen achieved a statistically significant and clinically meaningful functional cure rate, meeting the primary endpoint. In a key secondary endpoint, a higher rate of functional cure rate was achieved in participants with ≤1000 IU/ml HBsAg level. Functional cure occurs when the hepatitis B virus DNA and HBsAg are undetectable in the blood for at least 6 months after stopping all treatment, indicating the disease is controlled by the immune system without medication.

Regulatory review is ongoing in the US with a decision expected from the FDA by 26 October 2026. Reviews are also underway in Japan, China and the EU with further submissions to take place throughout 2026. If approved, bepirovirsen has the potential to become the first finite, six-month therapeutic option for CHB.

Bepirovirsen has been recognised by global regulatory authorities for its innovation and potential to address significant unmet need in CHB, with a Fast Track and Breakthrough Therapy designations from the US FDA, Breakthrough Therapy designation in China and SENKU designation in Japan.

To further expand development of novel sequential regimens, GSK entered an agreement for an exclusive worldwide license to develop and commercialise daplusiran/tomligisiran (GSK5637608, formerly JNJ-3989), an investigational hepatitis B virus-targeted small interfering ribonucleic acid (siRNA) therapeutic. This agreement provides an opportunity to investigate a novel sequential regimen to pursue functional cure in an even broader patient population with bepirovirsen. Phase IIb trials for this sequential therapy started in Q4 2024.

Utebzi (tebipenem HBr)

GSK has an exclusive licence agreement with Spero Therapeutics, Inc. for the development of tebipenem HBr (oral carbapenem antibiotic). In June 2026, the US FDA approved Utebzi for the treatment of complicated urinary tract infections (cUTIs) including pyelonephritis, caused by certain susceptible pathogens in adult patients who have limited or no alternative oral treatment options. This is the first and only oral carbapenem antibiotic approved for these patients, adding to GSK’s innovative anti-infectives portfolio and helping address the challenges of antimicrobial resistance (AMR).

Principal risks and uncertainties

The principal risks and uncertainties affecting the Group for 2026 are those described under the headings below. These are not listed in order of significance. In our December 2025 annual risk review, the Audit & Risk Committee agreed our principal and emerging risks and risk factors for 2026. Our existing principal risks remain relevant, with minor definition updates. Additionally, we agreed the following:

Geopolitical<br>and regulatory environment will be elevated to a new principal risk<br>in 2026 given the potential impact to our strategy. This risk will<br>continue to be overseen by the ExCom.
Capability,<br>skills and workforce planning will be elevated to a new risk factor<br>in 2026 given its relevance to our strategy for focused attention.<br>This risk will continue to be managed through a central HR<br>framework, embedded across our businesses.
Climate<br>change will continue to be a risk factor overseen by our<br>Sustainability Council in 2026.
We will<br>continue to embed the opportunities and risks related to<br>third-party relationships and artificial intelligence into our<br>principal risks, ensuring that risk assessments are comprehensive<br>and integrated, and enabling effective mitigating<br>actions.

We will maintain monitoring of the external landscape and make sure we adequately address any new emerging risks within our existing risk management governance.

We also include disclosures of our 2026 additional risk factors - risks that are not at the materiality threshold of principal risks - capability, skills and workforce planning and climate change - below.

We describe our risk management process on pages 63-65 of our 2025 Annual Report, along with more detailed information on our risks, including definitions, potential impact, context and mitigation activities as set out on pages 66-68 and 289-304 of our 2025 Annual Report.

Other business risks related to Responsible Business which are not at the level of principal risks, including environmental sustainability, are managed through our six focus areas, as described in our 2025 Responsible Business Performance Report. There is additional information on climate-related risk management in our climate-related financial disclosure on pages 69-76.

Reporting definitions

CAGR (Compound annual growth rate)

CAGR is defined as the compound annual growth rate and shows the annualised average rate for growth in sales and core operating profit between 2021 to 2026, assuming growth takes place at an exponentially compounded rate during those years.

CER and AER growth

In order to provide investors with a measure of year-on-year growth excluding the impact of exchange rate movements, it is the Group’s practice to discuss its results in terms of constant exchange rate (CER) growth. This represents growth calculated as if the exchange rates used to determine the results of overseas companies in Sterling had remained unchanged from those used in the comparative period. CER% represents growth at constant exchange rates. For those countries which qualify as hyperinflationary as defined by the criteria set out in IAS 29 ‘Financial Reporting in Hyperinflationary Economies’ (Argentina and Turkey) CER growth is adjusted using a more appropriate exchange rate where the impact is significant, reflecting depreciation of their respective currencies in order to provide comparability and not to distort CER growth rates.

AER% represents growth at actual exchange rates.

Core Earnings per share

Unless otherwise stated, Core earnings per share refers to Core basic earnings per share.

Core Operating Margin

Core Operating margin is Core operating profit divided by turnover. Core operating profit is a key financial measure used by management to evaluate performance.

Free cash flow

Free cash flow is defined as the net cash inflow/outflow from operating activities less capital expenditure on property, plant and equipment and intangible assets, contingent consideration payments, net finance costs, and distributions to non-controlling interests, contributions from non-controlling interests plus proceeds from the sale of property, plant and equipment and intangible assets, and dividends received from joint ventures and associates. Free cash flow provides investors with a measure of cash flows that are available to pay shareholder distributions and to fund strategic acquisitions. It is used by management for planning and reporting purposes and in discussions with and presentations to investment analysts and rating agencies. Free cash flow growth is calculated on a reported basis. A reconciliation of net cash inflow from operations to free cash flow from operations is set out on page 34.

Free cash flow conversion

Free cash flow conversion is free cash flow from operations as a percentage of profit attributable to shareholders. Free cash flow conversion provides investors with a measure of turning profit into cash.

General Medicines

General Medicines are usually prescribed in the primary care or community settings by general healthcare practitioners. For GSK, this includes medicines for inhaled respiratory, dermatology, antibiotics and other diseases.

Non-controlling interest (NCI)

Non-controlling interest is the equity in a subsidiary not attributable, directly or indirectly, to a parent.

Percentage points

Percentage points of growth which is abbreviated to ppts.

RAR (Returns and Rebates)

GSK sells to customers both commercial and government mandated contracts with reimbursement arrangements that include rebates, chargebacks and a right of return for certain pharmaceutical products principally in the US. Revenue recognition reflects gross-to-net sales adjustments as a result. These adjustments are known as the RAR accruals and are a source of significant estimation uncertainty and fluctuation which can have a material impact on reported revenue from one accounting period to the next.

Risk adjusted sales

Pipeline risk-adjusted sales are based on the latest internal estimate of the probability of technical and regulatory success for each asset in development.

Specialty Medicines

Specialty Medicines are typically prescription medicines used to treat complex or rare chronic conditions. For GSK, this comprises medicines for infectious diseases, HIV, Respiratory, Immunology & Inflammation, and Oncology.

Total Net debt

Net debt is defined as total borrowings less cash, cash equivalents, liquid investments, and short-term loans to third parties that are subject to an insignificant risk of change in value. The measure is used by management as it is considered a good indicator of GSK's ability to meet its financial commitments and the strength of its balance sheet (including those classified as assets held for sale and liabilities relating to assets held for sale).

Total and Core results

Total reported results represent the Group’s overall performance. GSK uses a number of non-IFRS measures to report the performance of its business. Core results and other non-IFRS measures may be considered in addition to, but not as a substitute for or superior to, information presented in accordance with IFRS. Core results are defined on page 14 and other non-IFRS measures are defined in pages 50 and 51.

Total Operating Margin

Total Operating margin is Total operating profit divided by turnover.

Total Earnings per share

Unless otherwise stated, Total earnings per share refers to Total basic earnings per share.

Working capital

Working capital represents inventory and trade receivables less trade payables.

Year to date

Year to date is the six-month period in the year to 30 June 2026 or the same prior period in 2025 as appropriate.

Guidance and Outlooks, assumptions and cautionary statements

2026 Guidance

GSK reaffirms its full-year 2026 guidance at constant exchange rates (CER), with further specificity provided.

GSK expects its turnover to increase between 3% to 5%, at the upper half of the range, and Core operating profit to increase between 7% to 9%, at the upper half of the range. Core earnings per share is expected to increase between 7% to 9%, at the lower half of the range.

The Group has made planning assumptions that we expect turnover for Specialty Medicines to increase by a low double-digit percentage, Vaccines to be broadly stable to an increase at a low-single digit percentage, and General Medicines to decline by a mid-single digit to low single-digit percentage.

2021-2026 and 2031 Outlooks

In February 2025 GSK set out improved outlooks for 2031 which are detailed in the 2024 full year and fourth quarter results on gsk.com(1).

Assumptions and basis of preparation related to 2026 Guidance, 2021-26 and 2031 Outlooks

In outlining the guidance for 2026, and outlooks for the period 2021-26 and for 2031, the Group has made certain assumptions about the macro-economic environment, the healthcare sector (including regarding existing and possible additional governmental legislative and regulatory reform), the different markets and competitive landscape in which the Group operates and the delivery of revenues and financial benefits from its current portfolio, its development pipeline and restructuring programmes, including the Accelerate Growth programme as outlined on page 3.

As previously announced, on 19 December 2025, GSK entered into an agreement with the US Administration to lower the cost of prescription medicines for American patients, which, once fully implemented, would exclude both GSK and ViiV Healthcare from Section 232 tariffs for three years. On 9 April 2026, GSK, ViiV Healthcare, and the US Government entered into a definitive agreement reflecting Section 232 tariff relief through 20 January 2029 (subject to final implementation). As part of that implementation, GSK and ViiV Healthcare each signed a Generous Model Manufacturer Participation Agreement with the Centers for Medicare and Medicaid Services effective 15 June 2026. With these agreements GSK and ViiV Healthcare have committed certain products to participate in the voluntary Generous Model, and it is anticipated that supplemental rebate agreements with interested US states will be signed on or before 1 October 2026. Our full year guidance is inclusive of the expected impact of these agreements.

2026 Guidance

These planning assumptions as well as operating profit, earnings per share guidance and dividend expectations assume no material interruptions to supply of the Group’s products, no material mergers, acquisitions or disposals, no material litigation or investigation costs for the Company (save for those that are already recognised or for which provisions have been made) and no change in the Group’s shareholdings in ViiV Healthcare. The assumptions also assume no material changes in the healthcare environment or unexpected significant changes in pricing or trade policies, including tariffs (except as noted above), as a result of government or competitor action. The 2026 guidance factors in all divestments and product exits announced to date.

2021-26 and 2031 Outlooks

The assumptions for GSK’s revenue, Core operating profit, Core operating margin and cash flow outlooks, 2031 revenue outlook and margin expectations through dolutegravir loss of exclusivity assume the delivery of revenues and financial benefits from its current and development pipeline portfolio of medicines and vaccines (which have been assessed for this purpose on a risk-adjusted basis, as described further below); regulatory approvals of the pipeline portfolio of medicines and vaccines that underlie these expectations (which have also been assessed for this purpose on a risk-adjusted basis, as described further below); no material interruptions to supply of the Group’s products; successful delivery of the ongoing and planned integration and restructuring plans, including the Accelerate Growth programme as outlined on page 3; no material mergers, acquisitions or disposals or other material business development transactions; no material litigation or investigation costs for the Company (save for those that are already recognised or for which provisions have been made); and no change in the Group's shareholdings in ViiV Healthcare. GSK assumes no premature loss of exclusivity for key products over the period.

The assumptions for GSK’s revenue, Core operating profit, Core operating margin and cash flow outlooks, 2031 revenue outlook and margin expectations through dolutegravir loss of exclusivity also factor in all divestments and product exits announced to date as well as material costs for investment in new product launches and R&D. Risk-adjusted sales includes sales for potential planned launches which are risk-adjusted based on the latest internal estimate of the probability of technical and regulatory success for each asset in development.

Notwithstanding our guidance, outlooks and expectations, there is still uncertainty as to whether our assumptions, guidance, outlooks and expectations will be achieved.

All outlook statements are given on a constant currency basis and use 2025 average exchange rates as a base (£1/$1.31, £1/€1.17, £1/Yen 198).

Assumptions and cautionary statement regarding forward-looking statements

The Group’s management believes that the assumptions outlined above are reasonable, and that the guidance, outlooks, and expectations described in this report are achievable based on those assumptions. However, given the forward-looking nature of these guidance, outlooks, and expectations, they are subject to greater uncertainty, including potential material impacts if the above assumptions are not realised, and other material impacts related to foreign exchange fluctuations, macro-economic activity, the impact of outbreaks, epidemics or pandemics, changes in legislation, regulation, government actions and policies, including the impact of any potential tariffs or other restrictive trade policies on the Group's products, or intellectual property protection, product development and approvals, actions by our competitors, and other risks inherent to the industries in which we operate.

This document contains statements that are, or may be deemed to be, “forward-looking statements”. Forward-looking statements give the Group’s current expectations or forecasts of future events. An investor can identify these statements by the fact that they do not relate strictly to historical or current facts. They use words such as 'aim', 'ambition', ‘anticipate’, 'believe', 'could', ‘estimate’, ‘expect’, ‘goal’, ‘intend’, 'may', ‘outlook’, ‘plan’, ‘project’, ‘seek’, ‘should’, ‘target’, 'will' and other words and terms of similar meaning in connection with any discussion of future operating or financial performance. In particular, these include statements relating to future actions, prospective products or product approvals, future performance or results of current and anticipated products, sales efforts, expenses, the outcome of contingencies such as legal proceedings, dividend payments and financial results. Other than in accordance with its legal or regulatory obligations (including under the Market Abuse Regulation, the UK Listing Rules and the Disclosure Guidance 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 readers are cautioned not to place undue reliance on the forward-looking statements.

All guidance, outlooks and expectations should be read together with the guidance and outlooks, assumptions and cautionary statements in this Q2 2026 earnings release and in the Group's 2025 Annual Report on Form 20-F.

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 ‘Risk Factors’ in the Group’s Annual Report on Form 20-F for 2025 and as described on pages 48 and 49 in this Q2 2026 earnings release. Any forward-looking statements made by or on behalf of the Group speak only as of the date they are made and are based upon the knowledge and information available to the Directors on the date of this report.

Independent review report to GSK plc

Conclusion

We have been engaged by GSK plc (“the company”) to review the condensed financial information in the Results Announcement of the company for the three and six months ended 30 June 2026.

The condensed financial information comprises:

the<br>income statement and statement of comprehensive income for the<br>three and six month periods ended 30 June 2026 on page 20 and<br>21;
the<br>balance sheet as at 30 June 2026 on page 22;
the<br>statement of changes in equity for the six-month period then ended<br>on page 23;
the<br>cash flow statement for the six-month period then ended on page 24;<br>and
the<br>accounting policies and basis of preparation and the explanatory<br>notes to the condensed financial information on pages 25 to 40 that<br>have been prepared applying consistent accounting policies to those<br>applied by GSK plc and its subsidiaries (“the Group”)<br>in the Annual Report 2025, which was prepared in accordance with<br>UK-adopted international accounting standards in conformity with<br>the requirements of the Companies Act 2006 and the IFRS Accounting<br>Standards as issued by the International Accounting Standards<br>Boards (IASB).

Based on our review, nothing has come to our attention that causes us to believe that the condensed financial information in the Results Announcement for the three and six months ended 30 June 2026 is not prepared, in all material respects, in accordance with United Kingdom adopted International Accounting Standard 34 and the Disclosure Guidance and Transparency Rules of the United Kingdom’s Financial Conduct Authority.

Basis for Conclusion

We conducted our review in accordance with International Standard on Review Engagements (UK) 2410 “Review of Interim Financial Information Performed by the Independent Auditor of the Entity” issued by the Financial Reporting Council for use in the United Kingdom (ISRE (UK) 2410). A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with International Standards on Auditing (UK) and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

As disclosed on page 31, the annual financial statements of the Group are prepared in accordance with United Kingdom adopted international accounting standards and IFRS Accounting Standards as issued by the international Accounting Standards Board (IASB). The condensed set of financial information included in this Results Announcement have been prepared in accordance with United Kingdom adopted International Accounting Standard 34, “Interim Financial Reporting”.

Conclusion Relating to Going Concern

Based on our review procedures, which are less extensive than those performed in an audit as described in the Basis for Conclusion section of this report, nothing has come to our attention to suggest that the directors have inappropriately adopted the going concern basis of accounting or that the directors have identified material uncertainties relating to going concern that are not appropriately disclosed.

This Conclusion is based on the review procedures performed in accordance with ISRE (UK) 2410, however future events or conditions may cause the entity to cease to continue as a going concern.

Responsibilities of the directors

The directors are responsible for preparing the Results Announcement of the company in accordance with the Disclosure Guidance and Transparency Rules of the United Kingdom’s Financial Conduct Authority.

In preparing the Results Announcement, the directors are responsible for assessing the company’s ability to continue as a going concern, disclosing as applicable, matters related to going concern and using the going concern basis of accounting unless the directors either intend to liquidate the company or to cease operations, or have no realistic alternative but to do so.

Auditor’s Responsibilities for the review of the financial information

In reviewing the Results Announcement, we are responsible for expressing to the company a conclusion on the condensed financial information in the Results Announcement. Our Conclusion, including our Conclusion Relating to Going Concern, are based on procedures that are less extensive than audit procedures, as described in the Basis for Conclusion paragraph of this report.

Use of our report

This report is made solely to the company in accordance with ISRE (UK) 2410. Our work has been undertaken so that we might state to the company those matters we are required to state to it in an independent review report and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the company, for our review work, for this report, or for the conclusions we have formed.
