We are building momentum as we transform and I am confident that we are firmly on track to deliver our full-year 2026 guidance. New Category revenue growth has accelerated to 18.0%2, driven by another strong performance from Modern Oral globally (up 65.9%2), and a return to double-digit growth2 in U.S. Vapour. This improving portfolio mix, together with our continued focus on quality growth and disciplined resource allocation in Heated Products and Vapour, drove an increase in New Category contribution of 54.7%. We further extended our global category leadership in Modern Oral, now our largest New Category (by revenue), achieving 39.2% volume share in our top markets4, up 8.4 ppts versus FY25. Revenue grew 65.9%2, driven by the continued excellent performance of Velo Plus in the U.S. and sustained double-digit growth2 in AME and APMEA. We delivered a robust performance in combustibles with revenue up 2.1%2, driven by the U.S. and AME, more than offsetting a slower than expected recovery in APMEA. We continue to drive value from combustibles to fund our transformation, while remaining focused on volume share globally. In H1 2026, we have actively increased investment in key markets in response to heightened competitive activity, including in the U.S., where our combustibles volume share has started to stabilise. In the U.S., the recently published FDA prioritisation guidance for Vapour and Modern Oral, together with other Federal and State enforcement actions, mean that BAT is well-positioned to benefit from our multi-category nicotine portfolio, leveraging Reynolds’ strong execution and extensive distribution capabilities. In the second half of 2026 we plan to roll out Velo Max nationally, together with a disciplined roll-out of a select range of adult-focused Vuse flavours. We expect mid-teens New Categories revenue growth for the full-year 2026, driven by continued global momentum in Modern Oral and further traction from innovation roll-outs, partly offset by lapping a higher second half comparator in the U.S. We continue to make good progress towards our year-end target leverage range of 2.0–2.5x while rewarding shareholders through strong cash returns. I remain committed to delivering sustainable value for our shareholders.” Change in Group Revenue: Reported +1.4% At CC2 +2.9% Reported diluted Adjusted diluted Adjusted for Canada diluted Adjusted for Canada diluted at CC 0 30 60 90 120 150 180 210 240 EXHIBIT 1 1 Adj Profit from Operations1,3 (£bn) YoY movements at constant rates -16.5 % +1.1 % +10.1 % Earnings per Share (pence) 167.7 164.0 167.8 145.3 Change in Group diluted EPS: Reported -28.6 % Adj1 at CC2 +5.9 % As adj for Canada1,3 +5.5 % As adj for Canada1,3 at CC2 +7.9 % 1.

Reported revenue increased 1.4% to £12,235 million, despite a translational foreign exchange headwind of 1.5%. On a constant currency basis, revenue grew by 2.9%, as: – The U.S. grew revenue (up 8.5%) with combustibles up 5.0% (driven by price/mix, including excise duty drawback, of +10.2% and short-term inventory movements) which were partly offset by lower volume (down 5.2%). New Categories grew 58.1%, driven by the success of Velo Plus (with revenue of Modern Oral up 220%) and Vapour up 19.8%; – AME increased by 0.9% led by combustibles (up 2.5% as price/mix of +8.7% offset a 6.2% decline in volume) and the growth of Modern Oral (up 21.8%), which drove New Categories revenue up 1.9%. However, Vapour was down 13.9% (largely due to regulatory changes in Poland) with HP down 10.8%, as growth in Romania was more than offset by higher investment due to competitive activity in Italy and Poland. – APMEA revenue was down 6.3%, mainly driven by the challenging regulatory environment and the impact of illicit combustibles volume in Bangladesh and Australia, the timing of inventory movements in Vietnam (driven by regulatory changes that were implemented in 2025) and lower volume in Malaysia, which more than offset higher revenue in Pakistan (led by pricing and a return to volume growth). HP was down 12.5%, largely due to inventory movements and heightened competition in Japan. In total, New Categories growth accelerated, with revenue up 18.0% on a constant rates basis driven by Modern Oral (up 65.9%). Vapour revenue returned to growth with an increase of 5.3%, while HP revenue was down 11.7%. We expect mid-teens New Categories revenue growth for the full-year 2026, driven by continued global momentum in Modern Oral and further traction from innovation roll-outs, partly offset by lapping a higher second half comparator in the U.S. Group cigarette volume share declined 30 bps and value share was down 40 bps with U.S. volume share declining 80 bps and value share down 40 bps.

Group Operating Review Continued Profit from operations, operating margin and category contribution Profit from operations on a reported basis was down 15.8%, with reported operating margin down 7.1 ppts to 34.9%. These were driven by higher adjusting items of £1,160 million (compared to £325 million in the six months ended 30 June 2025), due to: – a lower net credit of £38 million (30 June 2025: £575 million) in respect of the provision related to the Canadian litigation settlement described on page 26; and – costs of £370 million in respect of the Group's operational and process review programme (referred to as Fit2Win, as discussed on page 13); partly offset by – a credit of £149 million as the Group settled historical litigation with ITG Brands, which was treated as an adjusting item in the six months ended 30 June 2026; and – impairment charges in respect of Peru of £72 million recognised in the prior year that did not repeat (as discussed on page 26). The Group's performance in the six months ended 30 June 2026 was also negatively impacted by a translational foreign exchange headwind of 1.9% or £104 million. On an adjusted, constant currency basis, profit from operations increased 2.5% to £5,530 million (30 June 2025: £5,394 million). Included within the above was £109 million (30 June 2025: £154 million) related to the percentage (2026: 85%; 2025: 100%) of the Canadian business' net income after taxes (excluding New Categories)1 that forms the payment amounts to claimants as part of the settlement agreement. Adjusting for Canada1, adjusted profit from operations was up 3.5% to £5,421 million (30 June 2025: £5,240 million) at constant rates of exchange. Despite inflation on our product costs, estimated to be 3.7% (or £101 million at constant rates), this improvement in performance was largely due to: – the U.S., which grew by 10.1%; and – AME1 (up 1.1%); partly offset by – APMEA (down 16.5%), with the regional performance largely driven by the respective revenue performance discussed above. In aggregate, Group New Categories contribution was up £95 million to £269 million driven by Modern Oral (notably in the U.S. and with growth in AME) and Vapour, partially offset by higher investment in HP in APMEA (in Japan) and AME (in Italy, Poland and Romania). Adjusted operating margin was down 20 bps at 44.5% at constant rates of exchange, but was up 30 bps at 43.7% when adjusted for Canada1.

The term "NFC" refers to net finance costs. The term "SBB" refers to share buy-back. Basic earnings per share were down 28.6% to 146.1p (30 June 2025: 204.6p) due to lower profit from operations and items that benefitted the prior year and did not repeat, notably a gain of £333 million in respect of the demerger of the hotels division of the Group's Indian associate ITC and a provisional gain that arose on the partial sale of the Group's investment in ITC in 2025 of £904 million. However, in 2026, the Group recognised an adjusting credit to net finance costs of £315 million and an adjusting credit to taxation of £95 million related to the FII GLO litigation following further judgments by the Supreme Court in the UK, as discussed on page 36. Basic earnings per share were positively impacted by the reduction in the number of shares due to the cumulative effect of the 2025 and 2026 share buy-back programmes, with 14,609,571 ordinary shares repurchased and cancelled in the period. Before adjusting items, the impact of translational foreign exchange and including the dilutive effect of employee share schemes, adjusted diluted earnings per share, at constant rates, were up 5.9% to 171.6p (30 June 2025: 162.0p). Adjusted diluted earnings per share (as adjusted for Canada1) and at constant rates of exchange were 7.9% higher at 167.8p (30 June 2025: 155.5p). For a full reconciliation of diluted earnings per share to adjusted diluted earnings per share and adjusted diluted earnings per share (as adjusted for Canada1), both at constant rates, see page 54. Please also refer to page 57 for further reconciliations of profit from operations and diluted EPS to adjusted profit from operations1 and adjusted diluted EPS1 at both current and constant rates of exchange. 1.The adjustment in respect of Canada is discussed on pages 47 and 48, with the adjustment based upon a percentage (2026: 85%; 2025: 100%) of the net income after taxes earned from all sources, excluding New Categories, in Canada.

Regional Review The performances of the regions are discussed below. The following discussion is based upon the Group’s internal reporting structure. All references to volume share or value share movement in the following discussion are compared to FY 2025. See page 40 for a discussion on the use of these measures. Products sold in the U.S., including Vuse, Velo, Grizzly, Kodiak, and Camel Snus, are subject to FDA regulation and no reduced-risk claims will be made as to these products without agency clearance. United States (U.S.): – Reported revenue up 4.7%, an increase of 8.5% at constant rates. – Our Modern Oral category volume share increased 11.6 ppts to 29.8%, with Velo Plus driving strong revenue growth in Modern Oral, up 209% (or 220% at constant rates). – We increased our Vapour value share leadership in tracked channels (up 4.1 ppts to 55.9%), with Vapour revenue back to growth (up 15.6%), an increase of 19.8% at constant rates of exchange, driven by higher volume (up 14.9%). – Combustibles revenue up 1.3% (up 5.0% at constant rates) as short-term inventory movements and price/mix (including excise duty drawback) more than offset a 5.2% decline in volume. Volume share declined 80 bps with value share down 40 bps. – Smokeless now represents 22.7% of total revenue.

The preparation of the U.S. financial information is initially based on U.S. GAAP as the primary financial record and converted to IFRS for the purpose of consolidation within the results of the Group. Reported revenue increased 4.7%, despite a translational foreign exchange headwind negatively impacting revenue by 3.8%. On a constant currency basis, revenue increased 8.5%. This was driven by the performance in: – Combustibles, where revenue increased 5.0%, as price/mix (including excise duty drawback) of +10.2% and short-term inventory movements more than offset a 5.2% reduction in volume. This was higher than the industry volume decline of 4.0%, as our volume was negatively impacted by the growth in the low value segment where we are under-represented. Our value share was down 40 bps with volume share down 80 bps driven by Newport and Lucky Strike. However, our volume share has started to stabilise during H1 2026; – Modern Oral, where revenue increased by 220%, driven by higher volume (up 188%) following the continued growth of Velo Plus and Grizzly Modern Oral, with our volume share of Modern Oral up 11.6 ppts to 29.8%. We expect our performance to be further enhanced by the planned roll-out of Velo Max which is expected to commence in the second half of 2026. – Vapour, where the U.S. is the world's largest Vapour market. The Group extended its value share leadership (of Vapour closed systems consumables in tracked channels) with Vuse increasing value share by 4.1 ppts to 55.9%. Revenue grew 19.8% driven by higher volume (up 14.9%, partly due to changes in the competitor landscape in H2 2025 and the positive impact from progress in State level enforcement against illicit single-use vapour products) and price/mix (+4.9%). We expect our performance to be further enhanced as we roll out a select range of adult-focused Vuse flavours in the second half of 2026; and – Traditional Oral, where revenue declined 5.2%, as price/mix (+7.2%) was more than offset by lower volume (down 12.4%), due to the continued cross-category use of Modern Oral.

Reported profit from operations increased by 15.0%, partly due to a credit of £149 million as the Group settled historical litigation with ITG Brands. Accordingly, reported operating margin was up 4.1 ppts to 45.6%. Excluding adjusting items (largely in respect of the credit above and amortisation charges in both periods) and a translational foreign exchange headwind of £124 million, our performance was positively impacted by the growth in revenue (described above). Adjusted profit from operations, at constant rates of exchange was up 10.1% to £3,371 million.

Reported revenue increased 2.8% partly due to a translational foreign exchange tailwind of 1.9%. On a constant currency basis, which we believe reflects the operational performance, revenue was up 0.9% to £4,319 million, driven by: – Higher revenue from combustibles (up 2.5%), largely driven by Türkiye (led by pricing and further growth in volume) and pricing across a number of markets, including Brazil and Mexico, partially offset by lower volume in Brazil and Mexico. These factors combined to more than offset a reduction in revenue in Germany (resulting from higher investment due to competitive intensity and the growth in trade labels in which the Group is not present), the exit from Cuba and lower volume in Romania and Ukraine; and – Modern Oral, as volume was up 18.9% driving revenue up 21.8%. While volume share of the Modern Oral category was down 10 bps, we retained category leadership in our Top markets (as defined on page 46). The volume and revenue growth reflects the strength of our portfolio in both established oral markets across Scandinavia and markets with less of an established oral tradition, such as the UK and Poland. These were partly offset by: – Lower revenue from Vapour (down 13.9%), largely driven by regulatory changes in Poland, more than offsetting early signs of progress with Vuse Ultra in the premium segment. Our value share leadership was down 1.7 ppts with value share losses driven by heightened competition in the growing rechargeable closed systems category in Europe and Canada, with the latter also impacted by an increase in illicit volume; and – HP (down 10.8%), as higher revenue in Romania was more than offset by lower revenue in Poland (driven by increased competition) and in Italy as the Group invested in retail activation as part of the roll-out of glo Hilo and glo Hyper Pro+.

Reported profit from operations declined 38.4% as the Group recognised a lower net credit of £38 million (30 June 2025: £575 million) in respect of the provision related to the Canadian litigation settlement described on page 26 and a net loss of £12 million in respect of the Group's exit from Cuba. This was partly offset by a translational foreign exchange tailwind. Excluding the impact of foreign exchange and adjusting items, adjusted profit from operations was down 2.1% to £1,443 million as growth in Brazil (driven by combustibles pricing), Türkiye (driven by combustibles volume and pricing) and Scandinavia (driven by Modern Oral) was more than offset by Germany (discussed above), the investment in Italy (related to HP) and Romania (due to lower combustibles volume and investments in HP). Included within the above was £109 million (30 June 2025: £154 million) related to the Canadian business' net income after taxes (excluding New Categories) that forms the payment amounts to claimants as part of the settlement agreement. Adjusting for Canada1, adjusted profit from operations was up 1.1%, with adjusted operating margin up 10 bps at constant rates. 1. The adjustment in respect of Canada is discussed on pages 47 and 48, with the adjustment based upon a percentage (2026: 85%; 2025: 100%) of the net income after taxes earned from all sources, excluding New Categories, in Canada.

Reported revenue declined 8.9%, negatively impacted by a translational foreign exchange headwind of 2.6%. On a constant currency basis, which we believe reflects the operational performance, revenue was down 6.3% to £2,207 million. Modern Oral was up 43.2%, fuelled by growth in Japan, Pakistan, South Africa, Kenya, the United Arab Emirates and in Global Travel Retail, demonstrating Modern Oral's potential in the region. However, this was more than offset by lower revenue in: – Combustibles (down 4.8%), mainly due to the challenging regulatory environment and the impact of illicit volume in Bangladesh and Australia, the timing of inventory movements in Vietnam (driven by regulatory changes that were implemented in 2025) and lower volume in Malaysia, which more than offset higher revenue in Pakistan (led by pricing and a return to volume growth). Specifically in Australia, we estimate the illicit combustibles segment now accounts for around 80% of the combustibles industry volume, with the duty paid combustibles industry volume down more than 50% in the first half of 2026 (versus the same period in 2025); – Vapour, as volume declined 20.2%, leading to a 28.2% reduction in revenue, largely due to the Group's exit from the category in low revenue markets (Indonesia and South Korea) as the Group prioritises investment to drive Quality Growth; and – HP (down 12.5%), largely due to inventory movements and heightened competition in Japan.

Profit from operations was 45.7% lower, including a translational foreign exchange headwind of 0.9%. Excluding adjusting items and translational foreign exchange, adjusted profit from operations at constant rates was down 16.5% to £716 million driven by: – Japan, impacted by lower revenue and higher investment in HP; – Australia due to the lower revenue discussed above; and – Vietnam due to inventory movements discussed above. However, these were partly offset by an increase in Pakistan, which was positively impacted by combustibles pricing and growing combustibles volume.

Category Performance Review Modern Oral – Revenue up 66.6%, or 65.9% at constant rates, with volume growth of 57.5%. – Extended global category leadership with volume share* up 8.4 ppts. – AME volume share* leadership maintained, led by strong performances in Sweden and Denmark. – In the U.S., volume was up 188%, with revenue up 209% (up 220% at constant rates), driven by the growth of Velo Plus and Grizzly Modern Oral. In AME, volume was up 18.9%, driving revenue up 26.5% (or 21.8% at constant rates). While volume share of the Modern Oral category was down 10 bps, we retained category leadership in our Top markets (as defined on page 46). The volume and revenue growth reflects the strength of our portfolio in both established oral markets across Scandinavia and markets with less of an established oral tradition, such as the UK and Poland. In the U.S., revenue increased by 209% (or 220% at constant rates), driven by higher volume (up 188%) following the continued growth of Velo Plus and Grizzly Modern Oral, with our volume share of Modern Oral up 11.6 ppts to 29.8%. We expect our performance to be further enhanced by the planned roll-out of Velo Max which is expected to commence in the second half of 2026. In APMEA, our volume grew 27.5% and our revenue grew 37.4% (or 43.2% at constant rates), fuelled by growth in Japan, Pakistan, South Africa, Kenya, the United Arab Emirates and in Global Travel Retail, demonstrating Modern Oral's potential in the region. * Volume share is based upon the Top Modern Oral markets which are defined as the Group's priority Top Modern Oral markets by industry revenue. Top Modern Oral markets are the U.S., Sweden, Denmark, Norway, Switzerland, the UK and Poland, accounting for c.90% of total addressable industry Modern Oral revenue in 2025. Vapour – Continued value share* leadership (in tracked channels) up 1.2 ppts, driven by Vuse in the U.S. (up 4.1 ppts to 55.9%). – Vapour revenue up 3.6%, up 5.3% (at constant rates), with volume up 4.2%, driven by the U.S. but partially offset by regulatory changes in Poland. – In AME, Vapour value share down 1.7 ppts*, with industry rechargeable closed systems continuing to grow. – Vuse Ultra, our new premium product, continued to be rolled out in H1 2026, with further roll-outs planned for H2 2026. Group Vapour performance was driven by: – The U.S., the world's largest Vapour market, with Vuse volume up 14.9% partly due to changes in the competitor landscape in H2 2025 and the positive impact from progress in State level enforcement against illicit single-use vapour products and price/ mix (+4.9%). Accordingly in the U.S., revenue was up 15.6% (or 19.8% on a constant currency basis). The Group extended its value share leadership (of Vapour closed systems consumables in tracked channels) with Vuse increasing value share by 4.1ppts to 55.9%. We expect our performance to be further enhanced as we roll out a select range of adult-focused Vuse flavours in the second half of 2026. This was partially offset by; – AME, where revenue declined 11.9% (or 13.9% on a constant currency basis), largely driven by regulatory changes in Poland, more than offsetting early signs of progress with Vuse Ultra in the premium segment. Our value share leadership was down 1.7 ppts with value share losses driven by heightened competition in the growing rechargeable closed systems category in Europe and Canada, with the latter also impacted by an increase in illicit volume; and – APMEA, where volume declined 20.2%, leading to a 25.6% reduction in revenue (down 28.2% at constant rates), largely due to the Group's exit from the category in low revenue markets (Indonesia and South Korea) as the Group prioritises investment to drive Quality Growth. Our new premium innovation, Vuse Ultra, offers consumers a highly differentiated, connected and customisable experience. We are encouraged by the early performance in our launch markets and expect to continue the roll-out in a targeted way through H2 2026. * Based on Vuse estimated value share in measured retail for Vapour (i.e., value share of rechargeable closed systems consumables and disposables sales in retail) in the Top global markets. Top Vapour markets are defined as the Group's priority Top Vapour markets by industry revenue. Top Vapour markets are the U.S., Canada, the UK, France, Germany and Spain. These Top Vapour markets account for c.70% of total addressable industry vapour revenue (rechargeable closed systems consumables and disposables in tracked channels) in 2025. Heated Products (HP) – Revenue down 14.2%, down 11.7% at constant rates, driven by Japan due to inventory movements and heightened competition in the value segment. – Volume share*, down 1.2 ppts, reflecting heightened competition in the value segment. – AME volume share* down 70 bps with growth in Poland, Spain and Portugal, more than offset by Italy, Greece, Germany and the Czech Republic. – glo Hilo driving share growth (in premium/aspirational premium) in Japan, Poland and Italy and encouraging results in new launch markets (Romania and Greece). In APMEA, volume was down 18.0%, with revenue down 19.4%, a decrease of 12.5% at constant rates, largely due to inventory movements and heightened competition in Japan. In AME, volume was down 2.8%, with revenue down 8.8% (a decline of 10.8% at constant rates), as higher revenue in Romania was more than offset by lower revenue in Poland (driven by increased competition) and in Italy as the Group invested in retail activation as part of the roll-out of glo Hilo and glo Hyper Pro+. We expect to further enhance our portfolio in H2 2026 with Hilo amplification in the premium segment and with Hyper strengthening performance in the value segment through a phased roll-out of the Hyper Pro+ upgrade. * Volume share is based upon the Top HP markets which are defined as the Group's priority Top HP markets by industry revenue. Top HP markets are Japan, South Korea, Italy, Germany, Greece, Poland, Romania, the Czech Republic, Spain and Portugal. These Top HP markets account for c.80% of total addressable industry HP revenue in 2025.

Category Performance Review Continued Combustibles – Value share down 40 bps* and volume share down 30 bps*, as resilient volume share in AME (flat) was more than offset by the U.S. (down 80 bps) and APMEA (down 20 bps). – Revenue grew 0.5% (up 2.1% at constant rates) with higher category contribution (up 2.7%) driven by the U.S. and AME. – Return to growth in the U.S., with revenue up 1.3% (or 5.0% at constant rates) as price/mix (including excise duty drawback) more than offset volume decline (down 5.2%). – Resilient AME performance with revenue up 4.0%, or up 2.5% at constant rates, driven by Brazil and Türkiye, partly offset by Germany and Romania and the exit from Cuba. – APMEA revenue declined 7.0%, or 4.8% at constant rates, with volume down 2.8%, driven by lower volume in Bangladesh and Australia, the timing of inventory movements in Vietnam (driven by regulatory changes that were implemented in 2025) and lower volume in Malaysia, which more than offset higher revenue in Pakistan (led by pricing and a return to volume growth). Revenue from combustibles increased 0.5% to £9,561 million. Our performance was negatively impacted by a translational foreign exchange headwind, with revenue up 2.1% at constant rates as continued robust price/mix of +6.8% was partly offset by lower volume (down 4.7%). Group cigarette volume was down 4.6% to 218 billion sticks as volume growth in Pakistan and Türkiye was more than offset by lower volume in a number of markets, mainly driven by the U.S., Bangladesh, Malaysia, Romania and Ukraine, inventory movements in Vietnam (due to regulatory changes implemented in 2025) and market exits (including Cuba and Mozambique). Excluding the impact of translational foreign exchange: – In the U.S., revenue increased 5.0%, as price/mix (including excise duty drawback) of +10.2% and short-term inventory movements more than offset a 5.2% reduction in volume. This was higher than the industry volume decline of 4.0%, as our volume was negatively impacted by the growth in the low value segment where we are under-represented. Our value share was down 40 bps with volume share down 80 bps driven by Newport and Lucky Strike. However, our volume share has started to stabilise during H1 2026; – In AME, higher revenue (up 2.5%) was largely driven by Türkiye (led by pricing and further growth in volume) and pricing across a number of markets, including Brazil and Mexico, partially offset by lower volume in Brazil and Mexico. These factors combined to more than offset a reduction in revenue in Germany (resulting from higher investment due to competitive intensity and the growth in trade labels in which the Group is not present), the exit from Cuba and lower volume in Romania and Ukraine; and – In APMEA, revenue declined 4.8% due to the challenging regulatory environment and the impact of illicit volume in Bangladesh and Australia, the timing of inventory movements in Vietnam (driven by regulatory changes that were implemented in 2025) and lower volume in Malaysia, which more than offset higher revenue in Pakistan (led by pricing and a return to volume growth). * Volume and value share are based upon the Top cigarette markets which are defined as the Group's priority Top cigarette markets by industry revenue. Top cigarette markets are the U.S., Japan, Brazil, Germany, Pakistan, Mexico and Romania, accounting for c.50% of total addressable industry cigarette revenue in 2025. Traditional Oral Group volume declined 9.6% to 2.5 billion stick equivalents. Total revenue was £494 million (30 June 2025: £542 million), down 8.8% (or 5.8% at constant rates). In the U.S., which accounts for 97% of the Group's revenue from the category, revenue declined 8.5% or 5.2% at constant rates, as price/mix (+7.2%) was more than offset by lower volume (down 12.4%), due to the continued cross-category use of Modern Oral. Value share in the U.S. decreased 40 bps, with volume share down 60 bps, negatively impacted by continued consumer migration predominantly in the aspirational premium segment, where Grizzly is positioned. Outside the U.S., revenue declined 18.0%, or 22.5% at constant rates of exchange, largely due to the performance of Granit in Sweden. Beyond Nicotine Btomorrow Ventures has completed over 30 investments since its launch in 2020 and through the Group’s £350 million commitment towards the corporate venture capital fund. It invests to support the Group’s transformational journey to A Better Tomorrow™ focusing predominantly on Smokeless nicotine products, technology and capability enablers, sustainability and Wellbeing and Stimulation. The Group has also continued its exploration in the Wellbeing and Stimulation category with Ryde: functional shots now selling in the U.S. (through national online sales and retail primarily in Texas), in addition to Australia and Canada.

Other Financial Information Cash flow We continue to make good progress on de-leveraging our balance sheet and we expect to be within our narrowed leverage target range of 2.0-2.5x adjusted net debt/adjusted EBITDA (as adjusted for Canada1) by the end of 2026, driven by continued strong cash generation. Cash flow is typically weighted to the second half of the year. We are on track to meet or exceed our operating cash conversion guidance of 95%. We continue to expect the Group to generate c.£50 billion of free cash flow before dividends between 2024 and 2030 (inclusive). To date we have generated £14.2 billion. Our active capital allocation framework considers the continued investment in our transformation, the macro-environment, and potential future litigation and regulatory outcomes. We understand the importance of cash returns to shareholders, and remain committed to our progressive dividend based upon 65% of long-term sustainable earnings. For six months to 30 June 2026 2025 Change £m £m % Net cash generated from operating activities 3,402 2,309 47.3 % Operating cash flow conversion 80% 75% Free cash flow – before payment of dividends 2,285 1,234 85.2 % Free cash flow – after payment of dividends (349) (1,375) -75 % As at 30 June 2026 2025 Change £m £m % Borrowings (including lease liabilities) (35,063) (35,208) -0.4 % Adjusted net debt (31,969) (29,749) 7.5 % In the Group’s cash flow statement, prepared in accordance with IFRS and presented on page 22, net cash generated from operating activities increased by 47.3% to £3,402 million. This was largely due to: – lower payments in respect of the Franked Investment Income Group Litigation Order (FII GLO) of £111 million (of which £44 million was in respect of the principal, impacting net cash generated from operating activities, and £67 million was in respect of interest paid) compared to £368 million in the first six months of 2025, discussed on page 36; – lower tax paid as the first six months of 2025 included the net impact of the tax deferrals in the U.S. of £491 million (US$624 million) which did not repeat. Tax payments in the U.S. of £700 million (US$895 million) were deferred from 2024 to 2025, partly offset by deferral of £209 million (US$271 million) from the first half of 2025 to the second half of 2025; and – the receipt, in the first six months of 2026, of £149 million (US$200 million) from ITG Brands, LLC (ITG) in settlement of a dispute with respect to the liability arising under the Florida State Settlement Agreement, specifically regarding the four brands (Winston, Salem, Kool and Maverick) that were sold to ITG in 2015. Operating cash conversion and free cash flow (before and after dividends paid to shareholders) The Group’s operating cash conversion rate (based upon adjusted profit from operations and defined on page 54) increased to 80% (30 June 2025: 75%). We expect our operating cash conversion in 2026 to exceed 95%, demonstrating the ongoing strength of the Group in turning operating performance into cash. Free cash flow (before the payment of dividends), as defined on page 55, was £2,285 million for the six months ended 30 June 2026 (30 June 2025: £1,234 million), an increase of 85.2%. This was driven by the increase in net cash generated from operations discussed above, partly offset by an increase in net capital expenditure (30 June 2026: £155 million; 30 June 2025: £119 million). Net interest paid was in line with the prior period at £891 million (30 June 2025: £889 million). The Group expects its gross capital expenditure in 2026 to be approximately £750 million mainly related to the ongoing investment in the Group’s operational infrastructure, including the expansion of our New Categories portfolio and enhancements to our Modern Oral capacity. After paying dividends of £2,634 million (30 June 2025: £2,609 million), free cash flow (after dividends paid to shareholders), as defined on page 55, was an outflow of £349 million for the six months ended 30 June 2026 (30 June 2025: £1,375 million outflow). For a full reconciliation of net cash generated from operating activities to free cash flow before and after dividends, see page 55. 1. The adjustment in respect of Canada is discussed on pages 47 and 48, with the adjustment based upon a percentage (2026: 85%; 2025: 100%) of the net income after taxes earned from all sources, excluding New Categories, in Canada.

Other Financial Information Continued Borrowings and net debt Borrowings (which includes lease liabilities) were £35,063 million at 30 June 2026, a decrease of 0.4% compared to £35,208 million at 30 June 2025 (31 December 2025: £35,070 million). The Group remains confident of its ability to access the debt capital markets successfully and reviews its options on a continuing basis. The Group’s average centrally managed debt maturity of bonds was 9.3 years at 30 June 2026 (30 June 2025: 10.0 years; 31 December 2025: 9.5 years), and the highest proportion of centrally managed debt maturing in a single rolling 12-month period was 15.1% (30 June 2025: 15.3%; 31 December 2025: 15.1%). The Group defines net debt as borrowings (including related derivatives and lease liabilities), less cash and cash equivalents (including restricted cash) and current investments held at fair value. Closing net debt was £32,555 million at 30 June 2026 (30 June 2025: £30,342 million; 31 December 2025: £31,215 million). A reconciliation of borrowings to net debt is provided below.

Also impacting the carrying value of net debt are: – Cash payments largely related to share schemes and investing activities of £268 million (30 June 2025: £47 million); – The purchase of £649 million (30 June 2025: £450 million) of own shares under the Group’s 2026 and 2025 share buy-back programmes; – Other non-cash movements of £267 million (30 June 2025: £120 million); and – Foreign exchange impacts related to the revaluation of foreign currency denominated net debt balances which was a net headwind of £341 million (30 June 2025: £1,611 million tailwind). Included within both cash payments and other non-cash movements (above) is the classification of Cuba which was held-for- sale at 31 December 2025 (£208 million) and subsequently sold in 2026. On a net basis, cash payments (largely related to share schemes and investing activities) would have been £60 million (30 June 2025: £47 million) and other non-cash movements would have been £59 million (30 June 2025: £120 million). In the six months ended 30 June 2025, net debt was also impacted by net proceeds of £1,052 million from the partial monetisation of our investment in ITC in that period. Investments held at fair value through profit and loss above include restricted amounts of £nil (30 June 2025: £427 million; 31 December 2025: £nil) in respect of investments held by subsidiaries in CCAA protection as well as £nil (30 June 2025: £17 million; 31 December 2025: £nil) subject to potential exchange control restrictions. Cash and cash equivalents include restricted amounts of £386 million (30 June 2025 £2,047 million; 31 December 2025: £268 million) in Canada which, due to ongoing restrictions associated with the Approved Plans in Canada, continue to be considered restricted and £73 million (30 June 2025: £255 million; 31 December 2025: £67 million) principally due to exchange control restrictions. Adjusted net debt The Group also adjusts net debt for items held-for-sale and for the purchase price allocation adjustment to the debt, included within borrowings, acquired as part of the acquisition of Reynolds American Inc.

Other Financial Information Continued Foreign currencies The principal exchange rates used to convert the results of the Group’s foreign operations to pounds sterling for the purposes of inclusion and consolidation within the Group’s financial statements are indicated in the table below. Where the Group has provided results “at constant rates of exchange” this refers to the translation of the results from the foreign operations at rates of exchange prevailing in the prior period – thereby eliminating the potentially distorting impact of the movement in foreign exchange on the reported results. The principal exchange rates used were as follows: Average for the period ended As at 30 June 31 December 30 June 31 December 2026 2025 2025 2026 2025 2025 Australian dollar 1.915 2.045 2.045 1.916 2.091 2.017 Bangladeshi taka 165.056 158.273 160.886 163.517 168.176 164.432 Brazilian real 6.930 7.468 7.363 6.870 7.479 7.371 Canadian dollar 1.854 1.828 1.842 1.883 1.870 1.844 Chilean peso 1,201.588 1,238.902 1,253.837 1,223.851 1,279.119 1,212.663 Euro 1.153 1.187 1.167 1.161 1.167 1.145 Indian rupee 125.277 111.763 114.989 125.636 117.521 120.892 Japanese yen 212.718 192.489 197.243 215.711 197.940 210.830 Romanian leu 5.931 5.939 5.885 6.082 5.929 5.834 South African rand 22.076 23.859 23.562 21.754 24.353 22.287 Swiss franc 1.058 1.118 1.094 1.071 1.091 1.066 US dollar 1.345 1.298 1.319 1.327 1.370 1.345 Other Information Risks and uncertainties The Board carried out a robust assessment of the Principal Risks and uncertainties facing the Group for the period, including those that would threaten its business model, future performance, solvency, liquidity and viability. The Board also maintained close oversight of the Group’s response to critical external uncertainties, recognising current macro-economic and geopolitical challenges. All Group risks are reviewed biannually by the Audit Committee and annually by the Board. Leading in Sustainability is a core component and key building block of our corporate strategy and sustainability risk factors are embedded across the Group's risks in accordance with the management of these risks within the Group. The Principal Risks facing the Group are summarised under the headings of: – Competition from illicit trade; – Geopolitical tensions; – Tobacco, New Categories and other regulation interrupts the growth strategy; – Supply chain disruption; – Litigation and external investigations; – Significant increases or structural changes in tobacco, nicotine and New Categories related taxes; – Inability to develop, commercialise and deliver the New Categories strategy; – Disputed taxes, interest and penalties; – Injury, illness or death in the workplace; – Solvency and liquidity; – Foreign exchange rate exposures; – Climate change; – Circularity; and – Digital & Cyber. A summary of the Principal Risks which are monitored by the Board through the Group’s risk register is set out on pages 166 to 175 of the Group’s Annual Report and Accounts for the year ended 31 December 2025 and a summary of the risk factors is set out in Item 3.D - Risk Factors of the Group's annual report for the year ended 31 December 2025 on Form 20-F (the "2025 Form 20-F").

Other Information Continued Conflict in the Middle East We are closely monitoring developments in the Middle East. There is no significant impact on the Group at this time, and we have comprehensive business continuity plans in place to manage cost and supply-chain pressures. However, the broader macroeconomic and geopolitical backdrop is dynamic, increasing the risk of volatility in consumer sentiment should uncertainty persist. Update on investigations into misconduct allegations On 25 April 2023, the Group announced that it had reached agreement with the U.S. Department of Justice (DOJ) and Office of Foreign Assets Control (OFAC) to resolve previously disclosed investigations into suspicions of breaches of sanctions relating to the Democratic People’s Republic of Korea between 2007 and 2017. On 11 May 2026, the DOJ filed a motion to dismiss the legal proceedings against the Company, noting that the Company fully complied with the terms of the three-year deferred prosecution agreement, and the court entered an order dismissing the proceedings with prejudice the same day. The three-year probationary period imposed by the court on a BAT subsidiary in Singapore, British-American Tobacco Marketing (Singapore) Private Limited (BATMS), in connection with the subsidiary’s entry of a guilty plea in the same proceedings has also now expired. The Company’s compliance commitments under the civil settlement with OFAC remain in place until 2028. The Group investigates, and becomes aware of governmental authorities’ investigations into, allegations of misconduct, including alleged breaches of sanctions and allegations of corruption, at Group companies. Some of these allegations are currently being investigated, including by OFAC, which is investigating suspicions of breaches of sanctions. The Group cooperates with the authorities, where appropriate. In addition, the Group is, and may in the future be, subject to investigations or legal proceedings in relation to, among other things, its marketing, promotion or distribution activities in respect of its products. This includes, but is not limited to, allegations that such activities, whether undertaken through traditional channels, digital platforms, third parties, or distribution applications, do not comply with applicable laws or regulations. As such, the Group or Group companies, could be subject to liability and costs associated with any damages, fines, or penalties brought in connection with these allegations. There are instances where the Group investigates or where Group companies are cooperating with relevant national competition authorities in relation to competition law investigations and/or engaged in legal proceedings at the appellate level. Operational and process review To further support our transformation and underpin investment initiatives to drive long-term sustainable profit and cash flow growth, we are undertaking a structured time-bound programme (referred to as Fit2Win) to review processes and ways of working which will generate efficiencies and facilitate faster, more agile and effective decision making. Having commenced in 2025, the programme is expected to complete in 2027 and includes a comprehensive review of our overhead optimisation opportunities, route to market and digitalisation in order to deliver more effective, data-driven digital ways of working. The programme has also undertaken a global bottom-up review of our manufacturing assets and machinery, which will facilitate an upgrade to more efficient, next generation technologies to support our ongoing transformation. Accordingly, we have recognised an additional one-off, non-cash expense/charge of £228 million in 2026. During H1 2026, the programme has also identified additional potential optimisation opportunities of £100 million by the end of 2028, with a further £100 million of costs expected to be incurred over the life of the programme. Including the above, we now expect associated one-off costs of approximately £950 million (being non-cash items of £330 million and cash items of £620 million), with c.£840 million expected to be treated as adjusting items within adjusted profit from operations. By 30 June 2026, total costs of £482 million have been incurred since the programme commenced in 2025, with £459 million treated as adjusting items within profit from operations, of which £370 million was recognised in the six months ended 30 June 2026. The programme is expected to generate annualised cost efficiencies and cash flow of c.£700 million (previously £600 million) by the end of 2028 which will be re-invested to support further sustainable growth initiatives. By 30 June 2026, savings of c.£105 million have been realised, representing 15% of the total. These expected savings are in addition to the £2 billion of targeted savings between 2026 and 2030 announced at our Capital Markets Day in 2024. Changes in the Group Cuba As disclosed on page 328 of the Group’s Annual Report and Accounts for the year ended 31 December 2025 and page 170 of the 2025 Form 20-F, the Group entered into an agreement to sell its 50% shareholding in Brascuba Cigarrillos S.A. (Brascuba), its operating entity in the Republic of Cuba (Cuba), to Tabagest S.A. (Tabagest), a company incorporated in Cuba and an existing investor in Brascuba. Completion occurred in February 2026, at which point, the business was deconsolidated from the Group’s balance sheet. However, as the Cuban business was not significant to the users' understanding of that year or subsequent years financial performance, Management did not treat the sale of Cuban business as an organic adjustment. The net charge to the income statement in relation to the disposal of Brascuba was £12 million and includes the reclassification of foreign exchange losses previously recognised in the statement of comprehensive income of £4 million. ITC Ltd (ITC) As previously disclosed, in the six months ended 30 June 2025, the Group recognised: – a gain of £333 million (net of tax) related to the demerger of ITC's hotel business; and – a provisional gain of £904 million related to the disposal of 313.0 million shares in ITC (being 2.5% of ITC's ordinary shares). The Group received net proceeds of £1,052 million in 2025. Both were treated as adjusting items in 2025, with no comparable transactions in 2026.

The interim condensed consolidated financial information is unaudited but has been reviewed by the auditor and its review report is set out on page 15. This condensed consolidated financial information does not constitute statutory accounts within the meaning of Section 434 of the Companies Act 2006 and should be read in conjunction with the Group’s Annual Report and Accounts for the year ended 31 December 2025 and the 2025 Form 20-F, including the audited financial statements for the year ended 31 December 2025, which were prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB) and UK-adopted international accounting standards, and in accordance with the provisions of the UK Companies Act 2006. UK-adopted international accounting standards differ in certain respects from IFRS as issued by the IASB. The differences have no impact on the Group’s consolidated financial statements for the periods presented. The Group’s Annual Report and Accounts for the year ended 31 December 2025 represent the statutory accounts for that year and have been filed with the Registrar of Companies. The auditor’s report on those statements was unmodified and did not contain an emphasis of matter paragraph and did not contain any statement under Section 498 (2) or (3) of the Companies Act 2006. These condensed consolidated financial statements have been prepared under the historical cost convention, except in respect of certain financial instruments. They are prepared on a basis consistent with the IFRS accounting policies as set out in the Group’s Annual Report for the year ended 31 December 2025 and the 2025 Form 20-F. The preparation of these condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of revenues, expenses, assets and liabilities and the disclosure of contingent liabilities at the date of these condensed consolidated financial statements. Such estimates and assumptions are based on historical experience and various other factors that are believed to be reasonable in the circumstances and constitute management’s best judgement at the date of the condensed consolidated financial statements. Other than in respect of certain assumptions related to the assessment of the carrying value of goodwill and intangible assets, the key estimates and assumptions were the same as those that applied to the consolidated financial information for the year ended 31 December 2025, apart from updating the assumptions used to determine the carrying value of liabilities for retirement benefit schemes. As described on page 26, the Group has assessed whether there are any impairment triggers related to the carrying value of the significant investments of goodwill and intangibles. Other than as reported in prior periods, no further impairment is required. In the future, actual experience may deviate from these estimates and assumptions, which could affect these condensed consolidated financial statements as the original estimates and assumptions are modified, as appropriate, in the period in which the circumstances change. After reviewing the Group’s forecast financial performance and financing arrangements, the Directors consider that the Group has adequate resources to continue operating for at least 12 months from the date of approval of this condensed consolidated financial information and that it is therefore appropriate to continue to adopt the going concern basis in preparing this Half-Year Report. 2.

Notes to the Unaudited Interim Financial Statements (continued) 3. Adjusting Items Adjusting items are significant items of income or expense in profit from operations, net finance costs, taxation, the Group’s share of the post-tax results of associates and joint ventures, diluted earnings per share, net cash generated from operating activities and net debt which individually or, if of a similar type, in aggregate, are relevant to an understanding of the Group’s underlying financial performance because of their size, nature or incidence. In identifying and quantifying adjusting items, the Group consistently applies a policy that defines criteria that are required to be met for an item to be classified as adjusting. These items are separately disclosed in the segmental analyses or in the notes to the accounts as appropriate. The Group believes that these items are useful to users of the Group financial statements in helping them to understand the underlying business performance and are used to derive the Group’s non-GAAP measures of adjusted profit from operations, adjusted operating margin, adjusted gross profit, adjusted gross margin, adjusted EBITDA, New Categories contribution, New Categories contribution margin, adjusted net finance costs, adjusted taxation, adjusted diluted earnings per share, operating cash flow conversion ratio, adjusted cash generated from operations, free cash flow (before dividends paid to shareholders), free cash flow (after dividends paid to shareholders) and adjusted net debt, all of which are before the impact of adjusting items and which are reconciled from profit from operations, diluted earnings per share, net finance costs and taxation, cash conversion ratio, net cash generated from operating activities and net debt. In addition, the non-GAAP measures of adjusted gross profit, adjusted gross margin, adjusted profit from operations and adjusted operating margin, along with New Categories contribution, New Categories contribution margin, adjusted diluted earnings per share, adjusted net finance costs and adjusted taxation are presented with the additional adjustment to reflect the settlement of the Canadian litigation, and are referred to as "as adjusted for Canada"1. Such measures are also reconciled from profit from operations, diluted earnings per share, net finance costs and taxation. Along with operating cash flow conversion ratio, adjusted cash generated from operations, free cash flow (before dividends paid to shareholders) and free cash flow (after dividends paid to shareholders) referred to above these are collectively the Group's principal non-GAAP measures. 1. The adjustment in respect of Canada is discussed on pages 47 and 48, with the adjustment based upon a percentage (2026: 85%; 2025: 100%) of the net income after taxes earned from all sources, excluding New Categories, in Canada. Adjusting items included in profit from operations Adjusting items are significant items in the profit from operations that individually or, if of a similar type, in aggregate, are relevant to an understanding of the Group’s underlying financial performance. In summary, in the six months ended 30 June 2026, the Group incurred £1,160 million (30 June 2025: £325 million) of adjusting items within profit from operations: Six months ended 30 June 2026 2025 £m £m (a) Restructuring 370 13 (b) Amortisation and impairment of trademarks and similar intangibles 796 804 (b) Impairment of goodwill — 72 (c) Credit in respect of Romania's other taxes (2) (22) (c) Credit in respect of settlement of historical litigations with ITG brands (149) — (c) Other adjusting items (including Engle) 171 30 (c) Charges in connection with disposal of subsidiaries 12 — (d) Credit in respect of the Canada Approved Plans (38) (575) Charges in connection with disposal of associate — 3 Total adjusting items included in profit from operations 1,160 325 (a) Restructuring and integration costs To further support our transformation and underpin investment initiatives to drive long-term sustainable profit and cash flow growth, we are undertaking a structured time-bound programme (referred to as Fit2Win) to review processes and ways of working which will generate efficiencies and facilitate faster, more agile and effective decision making. Having commenced in 2025, the programme is expected to complete in 2027 and includes a comprehensive review of our overhead optimisation opportunities, route to market and digitalisation in order to deliver more effective, data-driven digital ways of working. The programme has also undertaken a global bottom-up review of our manufacturing assets and machinery, which will facilitate an upgrade to more efficient, next generation technologies to support our ongoing transformation. Accordingly, we have recognised an additional one-off, non-cash expense/charge of £228 million in 2026. During H1 2026, the programme has also identified additional potential optimisation opportunities of £100 million by the end of 2028, with a further £100 million of costs expected to be incurred over the life of the programme. Including the above, we now expect associated one-off costs of approximately £950 million (being non-cash items of £330 million and cash items of £620 million), with c.£840 million expected to be treated as adjusting items within adjusted profit from operations. By 30 June 2026, total costs of £482 million have been incurred since the programme commenced in 2025, with £459 million treated as adjusting items within profit from operations, of which £370 million was recognised in the six months ended 30 June 2026.

Notes to the Unaudited Interim Financial Statements (continued) 3. Adjusting Items (continued) Adjusting items included in profit from operations (continued) (b) Amortisation and impairment of trademarks and similar intangibles (b)(i) Amortisation Acquisitions in previous years have resulted in the capitalisation of trademarks and similar intangibles, including those which are amortised over their expected useful lives, which do not exceed 30 years. The element of the total amortisation and impairment charge treated as an adjusting item was £796 million (30 June 2025: £804 million) and is included within depreciation, amortisation and impairment costs in the income statement. (b)(ii) Ongoing impairment review of trademarks and similar assets The Group reviews and monitors the performance of its non-financial assets (including goodwill) in line with the requirements of IAS 36 Impairment of Assets. In preparing the Half-Year Report for the six months ended 30 June 2026, the Group has assessed if any impairment indicators exist requiring a further detailed impairment assessment to be undertaken. In the U.S., no changes have occurred in the legislative environment, nor in the macro-economic environment, during the six months ended 30 June 2026 that present an indicator of a potential impairment for either Reynolds American goodwill or for the definite- or indefinite-lived brands. As part of the standard year-end impairment process, a detailed impairment review will be undertaken for all trademarks in line with IAS 36 Impairment of Assets. This will include the entire Reynolds American portfolio to ensure the book values remain supportable. (b)(iii) Impairment of goodwill In the six months ended 30 June 2026, no impairment trigger has been identified in respect of goodwill (including in respect of the U.S. and Canada), having recognised a goodwill impairment charge of £72 million in the six months ended 30 June 2025 in respect of the Peru cash-generating unit. (c) Other In the six months ended 30 June 2026, the Group incurred a net charge of £32 million (30 June 2025: £8 million) of other adjusting items. These included: – A credit of £149 million as the Group settled historical litigation with ITG Brands; – A net loss associated with the disposal of the business in Cuba of £12 million; – A credit of £2 million (30 June 2025: £22 million) in respect of the partial release of a provision recognised in December 2024 in relation to an excise assessment of activities undertaken in the Ploiesti factory in Romania; and – Other costs of £171 million (30 June 2025: £30 million), mainly related to foreign exchange reclassified from reserves to the income statement as a consequence of the cessation of a physical presence in certain countries. In the six months ended 30 June 2025, other costs mainly related to litigation costs including Engle progeny cases. (d) Changes in provision in relation to Canada Approved Plans The Group's estimated share of the undiscounted future liability in relation to the court-sanctioned plan of compromise and arrangement to resolve all Canadian tobacco litigation in relation to the Group and other parties (the Approved Plans) in Canada has not materially changed. The Group recognised a net credit of £38 million in the six months ended 30 June 2026 due to minor revisions to the assumptions, including the pre-tax discount rate decreasing from 3.86% at 31 December 2025 to 3.79% at 30 June 2026. This compares to a net credit of £575 million (in the six months ended 30 June 2025) mainly in respect of pricing and volume decline assumptions. Based on our current estimate, it is expected that payments in respect of our estimated share of the future liability will continue for at least 40 years. At 30 June 2026, net of translational FX movements, unwinding of discount and the above factors, the non-current provision for the future payments is £2,752 million (31 December 2025: £2,794 million). Within current trade and other payables, an amount of £83 million is due to be paid in the second half of 2026. Management uses judgement to determine the key assumptions used to calculate the present value of the provision. Changes to key assumptions can significantly impact the amount expected to be paid and the years over which payments are expected to be made. A combination of changes in several assumptions, including the future financial performance (excluding New Categories) of Imperial Tobacco Canada Limited's and Imperial Tobacco Company Limited's (together, ITCAN) and each of the other companies (JTI-MacDonald Corp (a subsidiary of Japan Tobacco International) and Rothmans, Benson & Hedges Inc. (a subsidiary of Philip Morris International Inc.)) and the performance of the combustibles industry as a whole, may materially impact the provision. Refer to note 4 for the unwinding of the discount in the six months ended 30 June 2026. Please refer to pages 319 to 320 of the Group's Annual Report and Accounts for the year ended 31 December 2025 and pages 162 to 163 of the 2025 Form 20-F for further information on the Approved Plans including the impact of possible changes to key assumptions.

Notes to the Unaudited Interim Financial Statements (continued) 4. Net finance costs Net finance costs were a charge of £403 million, compared to a charge of £969 million in the same period in 2025. 2026 was impacted by a translational foreign exchange tailwind due to the relative movement of sterling of 1.4%. The Group considers that, following the judgment by the Supreme Court in the UK, the legal proceedings concerning the Franked Investment Income Group Litigation Order (FII GLO) has now reached its conclusion. Accordingly, an adjusting net credit to net finance costs of £315 million has been recognised in the six months ended 30 June 2026. This compares to a finance cost of £19 million in the six months to 30 June 2025. For further detail please refer to note 15. The performance in 2026 included a charge of £54 million (30 June 2025: £59 million) related to the unwinding of the discount in relation to the provision associated with the Approved Plans in Canada. The first six months of 2025 also included a charge of £10 million related to interest on unaffected claims settled post sanctioning of the Approved Plans. These charges were all treated as adjusting items. Also included in the first six months of 2026 is a net gain on monetary items in Venezuela of £139 million resulting from the application of hyperinflation accounting under IAS 29 Financial Reporting in Hyperinflationary Economies. This gain was treated as an adjusting item. The first six months of 2026 included a fair value loss of £nil (30 June 2025: £4 million) on embedded derivatives related to associates, a charge of £6 million (30 June 2025: £3 million) in relation to a tax case in Brazil, a credit of £2 million (30 June 2025: £nil) in respect of a tax provision in Indonesia and interest charges of £5 million (30 June 2025: £3 million) in respect of a tax provision in the Netherlands. These are treated as adjusting items. On an adjusted, constant currency basis, net finance costs were £806 million, a decrease of 7.5% (30 June 2025: £871 million). This was driven by: – Lower transactional foreign exchange losses arising from revaluation of locally held cash balances and dividend receivables, as well as fair value movements in respect of derivatives and investments; – Lower interest expense, principally driven by lower borrowings; and – Partially offset by lower interest income, driven by lower interest income in Canada due to reduced cash held, partially offset by increased interest income in Türkiye due to higher local deposits. The Group's average cost of debt, including foreign exchange losses and fair value movements, was 4.9% (compared to 5.1% at 30 June 2025). Also in 2026, in line with IAS 33 Earnings Per Share, £28 million (30 June 2025: £22 million), net of tax, has been recognised as a deduction to EPS related to the perpetual hybrid bonds. In 2021, the Company issued two €1 billion aggregate principal amount perpetual hybrid bonds. During 2025, the Group repurchased €1 billion aggregate principal amount of perpetual hybrid bonds and issued a further €1.2 billion aggregate principal amount of perpetual hybrid bonds. The coupons paid on such instruments are recognised in equity rather than as a charge to the income statement in net finance costs. For a full reconciliation of net finance costs to adjusted net finance costs at constant rates, see page 52. All of the adjustments noted above have been included in the adjusted earnings per share calculation on page 29. 5. Results of associates and joint ventures In the six months to 30 June, the Group’s share of post-tax results of associates and joint ventures decreased from £1,474 million in 2025 to £189 million in 2026. The decrease was largely due to the following adjusting gains, recognised in the six months ended 30 June 2025 and which did not repeat: – a provisional gain of £904 million (net of tax) following the disposal of 313,000,000 ordinary shares in the Group's interest in its associate ITC Ltd (ITC) in India; and – £333 million (net of tax) related to the demerger of ITC's hotel business (ITC Hotels). Following a partial sale of the Group's holding in ITC Hotels in the second half of 2025, the Group now holds a direct stake of 6.3% in ITC Hotels, presented as a non- current investment on the balance sheet and held at fair value. During the period, a deemed gain of £1 million (30 June 2025: £3 million) was recognised as a result of ITC issuing ordinary shares under the company’s Employees Share Option Scheme. As a result, the Group's shareholding in ITC has decreased from 22.91% (31 December 2025) to 22.90%. In February 2026, Organigram announced the acquisition of Sanity Group GmbH (Sanity). As previously disclosed, prior to the acquisition; – the Group's ownership of Organigram was 36.77%, with voting rights restricted to 30%; and – the Group ownership of Sanity was 16.32%. Under the terms of the acquisition, the Group sold its holding in Sanity in exchange for shares in Organigram; in addition, the Group subscribed to 12% of the issued and outstanding share capital in Organigram for £35 million (CAD$65 million). Post acquisition, the Group retains no continuing involvement in Sanity other than through its investment in Organigram. Further, at 30 June 2026, the Group's shareholding in Organigram was 48.7% and may change, subject to certain earnout provisions in relation to Organigram's acquisition of Sanity. However, there was no change to the Group's voting rights which remain restricted to 30%. In May 2026, the Group completed the conversion of a loan to Charlotte’s Web Holdings into ordinary shares, concurrently making an additional equity investment of £7 million (US$10 million). Excluding the impact of translational foreign exchange and the adjusting items in the six months ended 30 June 2025, on an adjusted constant currency basis, the Group’s share of post-tax results from associates and joint ventures was lower than in the first half of 2025, down 8.9% to £211 million, partly as a result of the reduction in the Group's shareholding in ITC. For a full reconciliation of the Group's share of post-tax results of associates and joint ventures to adjusted share of post-tax results of associates and joint ventures, at constant rates of exchange, see page 52. For the impact on the calculation of adjusted earnings per share, see page 29.

Notes to the Unaudited Interim Financial Statements (continued) 6. Taxation The tax rate in the income statement was a charge of 20.3% for the six months to 30 June 2026 (30 June 2025: 18.1%). The Group’s tax rate is affected by the impact of the adjusting items referred to on pages 25 to 27 and by the inclusion of the share of associates and joint ventures post-tax profit in the Group’s pre-tax results. Adjusting items in the six months ended 30 June 2026 included £100 million (30 June 2025: £66 million) mainly reflecting the recognition of a tax credit in respect of the FII GLO litigation (described further on page 36 below) which, following the judgment by the Supreme Court in the UK, the Group considers to have reached a conclusion. The adjusting items in 2025 mainly reflect the revaluation of deferred tax liabilities arising on trademarks recognised in the Reynolds American acquisition in 2017 due to changes in applicable U.S. state tax rates and apportionment factors. The adjusting tax item also includes £179 million (30 June 2025: £29 million) in respect of the taxation on other adjusting items, which are described on pages 25 to 26. As the above items are not reflective of the ongoing business, they have been recognised as adjusting items within taxation. All of the adjustments noted above have been included in the adjusted earnings per share calculation on page 29. Excluding these, the Group’s underlying tax rate for subsidiaries reflected in the adjusted earnings per share on page 29 was 23.8% for the six months to 30 June 2026 (30 June 2025: 24.4%). The reduction in the Group's underlying tax rate for subsidiaries is primarily driven by changes in the mix of profits and movements associated with prior periods (including tax audit outcomes and the net impact of Pillar 2 filings for FY 2024). A full reconciliation from taxation on ordinary activities to the underlying tax rate is provided on page 53. The Group has applied the mandatory exemption to recognising and disclosing information about deferred tax assets and liabilities related to Pillar Two income taxes in accordance with IAS 12 Income Taxes. 7. Earnings per share Basic earnings per share were down 28.6% to 146.1p (30 June 2025: 204.6p) due to lower profit from operations and items that benefitted the prior year and did not repeat, notably a gain of £333 million in respect of the demerger of the hotels division of the Group's Indian associate ITC and a provisional gain that arose on the partial sale of the Group's investment in ITC in 2025 of £904 million. However, in 2026, the Group recognised an adjusting credit to net finance costs of £315 million and an adjusting credit to taxation of £95 million related to the FII GLO litigation following further judgments by the Supreme Court in the UK, as discussed on page 36. Basic earnings per share were positively impacted by the reduction in the number of shares due to the cumulative effect of the 2025 and 2026 share buy-back programmes, with 14,609,571 ordinary shares repurchased and cancelled in the period ended 30 June 2026. Before adjusting items, the impact of translational foreign exchange and including the dilutive effect of employee share schemes, adjusted diluted earnings per share, at constant rates, were up 5.9% to 171.6p (30 June 2025: 162.0p). For a full reconciliation of diluted earnings per share to adjusted diluted earnings per share at constant rates, see page 54. Earnings used in the basic, diluted and headline earnings per share calculation represent the profit attributable to the ordinary equity shareholders after deducting amounts representing the coupon on perpetual hybrid bonds on a pro-rata basis regardless of whether or not coupons have been declared and paid in the period. In 2026, this was £28 million (30 June 2025: £22 million), net of tax.

For the calculation of the diluted earnings per share, the weighted average number of shares reflects the potential dilutive effect of employee share schemes. Earnings per share calculations are based upon the following : Reported Adjusted Headline Basic Diluted Basic Diluted Basic Diluted Six months to 30 June 2026 – Earnings £m 3,162 3,162 3,650 3,650 3,436 3,436 – Shares m 2,165 2,176 2,165 2,176 2,165 2,176 – Per share p 146.1 145.3 168.6 167.7 158.7 157.9 Six months to 30 June 2025 – Earnings £m 4,490 4,490 3,573 3,573 3,698 3,698 – Shares m 2,194 2,205 2,194 2,205 2,194 2,205 – Per share p 204.6 203.6 162.9 162.0 168.5 167.7 BAT Interim Announcement 2026 Summary Performance Review Financial Statements Other Information Data Lake and Reconciliations 28

Notes to the Unaudited Interim Financial Statements (continued) 8. Cash Flow Net cash generated from operating activities Net cash generated from operating activities in the IFRS cash flows on page 22 includes the following items: Six months ended 30 June 2026 2025 £m £m Profit for the period 3,228 4,565 Taxation on ordinary activities 824 1,009 Share of post-tax results of associates and joint ventures (189) (1,474) Net finance costs 403 969 Profit from operations 4,266 5,069 Adjustments for: – depreciation, amortisation and impairment costs 1,364 1,192 – increase in inventories (448) (696) – increase in trade and other receivables (102) (1) – decrease in Master Settlement Agreement payable (571) (633) – decrease in trade and other payables (160) (565) – decrease in retirement benefit liabilities (15) (27) – decrease in other provisions for liabilities (70) (634) – other non-cash items 223 12 Cash generated from operating activities 4,487 3,717 Dividends received from associates 139 168 Tax paid (1,224) (1,576) Net cash generated from operating activities 3,402 2,309 Net cash generated from operating activities increased by £1,093 million. This was largely due to: – lower payments in respect of the Franked Investment Income Group Litigation Order (FII GLO) of £111 million (of which £44 million was in respect of the principal, impacting net cash generated from operating activities, and £67 million was in respect of interest paid) compared to £368 million in the first six months of 2025, discussed on page 36; – lower tax paid as the first six months of 2025 included the net impact of the tax deferrals in the U.S. of £491 million (US$624 million) which did not repeat. Tax payments in the U.S. of £700 million (US$895 million) were deferred from 2024 to 2025, partly offset by deferral of £209 million (US$271 million) from the first half of 2025 to the second half of 2025; and – the receipt, in the first six months of 2026, of £149 million (US$200 million) from ITG Brands, LLC (ITG) in settlement of a dispute with respect to the liability arising under the Florida State Settlement Agreement, specifically regarding the four brands (Winston, Salem, Kool and Maverick) that were sold to ITG in 2015. Please refer to page 354 of the Group's Annual Report and Accounts for the year ended 31 December 2025 and pages 191 and 192 of the 2025 Form 20-F. Also included within net cash generated from operating activities were litigation receipt of £2 million (30 June 2025: payment of £42 million) which included, in both 2026 and 2025, payments in respect of Engle progeny cases (see page 35 for further details). Expenditure on research and development was approximately £188 million for the six months to 30 June 2026 (30 June 2025: £174 million) with a focus on products that could potentially reduce the risk associated with smoking conventional cigarettes. The Group’s customer factoring arrangements and supplier financing arrangements were disclosed on pages 302 and 320 to 321, respectively, in the 2025 Annual Report and Accounts and pages 148 and 164 in the 2025 Form 20-F for the year ended 31 December 2025. There have been no material changes in these underlying arrangements. At 30 June 2026, the total amount factored under customer factoring arrangements was £667 million (30 June 2025: £674 million). In addition, where the Group acts as a collection agent for the banks and other financial institutions, the cash collected that has not yet been remitted amounted to £132 million (30 June 2025: £122 million). Net cash from investing activities Net cash from investing activities was an outflow of £300 million, a decline of £1,312 million from the same period last year when it was an inflow of £1,012 million. The decline was largely due to: – the partial monetisation of our investment in ITC in 2025 (30 June 2026: £nil; 30 June 2025: £1,052 million); and – a lower net inflow of £10 million (compared to a net inflow of £14 million in the six months ended 30 June 2025) from short-term investment products, including treasury bills. Purchases of property, plant and equipment were higher than in 2025, at £134 million (30 June 2025: £103 million). Included within investing activities is gross capital expenditure. This includes the investment in the Group’s global operational infrastructure (including, but not limited to, the manufacturing network, trade marketing and IT systems). In 2026, the Group invested £163 million, an increase of 16.4% on the prior year (30 June 2025: £140 million). The Group expects its gross capital expenditure in 2026 to be approximately £750 million mainly related to the ongoing investment in the Group’s operational infrastructure, including the expansion of our New Categories portfolio and enhancements to our Modern Oral capacity.

Notes to the Unaudited Interim Financial Statements (continued) 8. Cash Flow (continued) Net cash used in financing activities Net cash used in financing activities was an outflow of £4,663 million in 2026 (30 June 2025: £4,117 million outflow). The total outflow includes: – The payment of the dividend of £2,634 million (30 June 2025: £2,609 million); – Interest paid in the period of £905 million (30 June 2025: £879 million), with the increase driven by the payment of interest in respect of FII GLO (£67 million), partly offset by lower interest payments in line with a reduction in gross borrowing and a lower average cost of debt of 4.9% (compared to 5.1% at 30 June 2025); – A net outflow from the issuance and repayment of borrowings in 2026 of £151 million (30 June 2025: £505 million net inflow); – An outflow of £39 million related to derivatives (30 June 2025: outflow of £445 million); and – An outflow of £649 million (30 June 2025: £450 million) in respect of the share buy-back programme. 9. Supplier Financing Arrangements The Group has certain supplier financing arrangements or ‘reverse factoring’ arrangements in place. The principal purpose of these arrangements is to provide the supplier with the option to access liquidity earlier through the sale of its receivables due from the Group to a bank or other financial institution prior to their due date. Management has determined that the Group’s payables to these suppliers have neither been extinguished nor have the liabilities been significantly modified by these arrangements. The value of amounts payable, invoice due dates and other terms and conditions applicable, from the Group’s perspective, remain unaltered, with only the ultimate payee being changed. Non-cash movements were immaterial. The cash outflows in respect of these arrangements have been recognised within operating cash flows. As at 30 June As at 31 December 2026 2025 2025 £m £m £m Supplier Financing Arrangements Total Amounts available for financing reported within trade payables 129 115 296 Amounts accepted by financial institutions for early financing 123 100 287 Amounts for which suppliers have received payment 90 80 274 Analysed as: Leaf payables Amounts available for financing reported within trade payables 3 — 188 Amounts accepted by financial institution for early financing 2 — 182 Amounts for which suppliers have received payment 2 — 180 Other payables Amounts available for financing reported within trade payables 126 115 108 Amounts accepted by financial institution for early financing 121 100 105 Amounts for which suppliers have received payment 88 80 94 There has been no significant change in the supplier due dates that were disclosed in note 25 on page 321 in the Annual Report and Accounts for the year ended 31 December 2025 and page 164 in the 2025 Form 20-F.

Notes to the Unaudited Interim Financial Statements (continued) 10. Liquidity The Treasury function is responsible for raising finance for the Group, managing the Group’s cash resources and the financial risks arising from underlying operations. All these activities are carried out under defined policies, procedures and limits, reviewed and approved by the Board, delegating oversight to the Finance Director and Treasury function. The Group has targeted an average centrally managed bond maturity of at least five years with no more than 20% of centrally managed debt maturing in a single rolling 12-month period. As at 30 June 2026, the average centrally managed debt maturity of bonds was 9.3 years (30 June 2025: 10.0 years; 31 December 2025: 9.5 years) and the highest proportion of centrally managed debt maturing in a single rolling 12-month period was 15.1% (30 June 2025: 15.3%; 31 December 2025: 15.1%). The Group continues to maintain investment-grade credit ratings, with ratings from Moody’s, S&P and Fitch at Baa1 (stable outlook), BBB+ (stable outlook) and A- (stable outlook), respectively, with a medium-term target of Baa1, BBB+ and BBB+. The strength of the ratings has underpinned debt issuance and the Group is confident of its ability to continue to successfully access the debt capital markets. A credit rating is not a recommendation to buy, sell or hold securities. A credit rating may be subject to withdrawal or revision at any time. Each rating should be evaluated separately of any other rating. In order to manage its interest rate risk, the Group maintains both floating and fixed rate debt. The Group sets targets (within overall guidelines) for the desired ratio of floating to fixed rate debt on a net basis (at least 50% fixed on a net basis in the short to medium term). At 30 June 2026, the relevant ratio of floating to fixed rate borrowings after the impact of derivatives was 25:75 (30 June 2025: 26:74; 31 December 2025: 24:76). Excluding cash and other liquid assets in Canada, which are subject to restrictions associated with the Approved Plans in Canada, the ratio of floating to fixed rate borrowings was 20:80 (30 June 2025: 20:80; 31 December 2025: 14:86). Available facilities It is Group policy that short-term sources of funds (including drawings under both the US$4 billion U.S. commercial paper programme and £3 billion euro commercial paper programme) are backed by undrawn committed lines of credit and cash. As at 30 June 2026, commercial paper of £157 million was outstanding (30 June 2025: £700 million; 31 December 2025: £nil). Cash flows relating to commercial paper issuances with maturity periods of three months or less are presented on a net basis in the Group’s cash flow statement. At 30 June 2026, the Group had access to a £5.0 billion revolving credit facility. This revolving credit facility was undrawn at 30 June 2026. In November 2025, the Group refinanced its existing £5.2 billion facility at the reduced amount of £5.0 billion comprising (i) a £2.5 billion 364-day tranche with two one-year extension options and a one-year term-out option and (ii) a £2.5 billion five-year tranche with two one-year extension options. During the first six months of 2026, the Group refinanced or extended short-term bilateral facilities. These facilities totalled £2.3 billion as at 30 June 2026, targeting to maintain £2.4 billion in the current financing cycle. As at 30 June 2026, £415 million was drawn on a short-term basis with £1.9 billion undrawn and still available under such bilateral facilities. Cash flows relating to bilateral facilities that have maturity periods of three months or less are presented on a net basis in the Group’s cash flow statement. In January 2025, the Group entered into a medium-term facility of £475 million (equivalent), which was fully drawn as at 30 June 2026. Issuance, drawdowns and repayments in the period – In March 2026, the Group repaid a US$1.5 billion bond at maturity; and – In May 2026, the Group accessed the Euro market under its EMTN Programme, raising a total of €500 million.

Notes to the Unaudited Interim Financial Statements (continued) 11. Fair value measurements and valuation processes The Group held certain financial instruments at fair value at 30 June 2026. The definitions and valuation techniques employed for these as at 30 June 2026 are consistent with those used at 31 December 2025 and disclosed in Note 26 on pages 322 to 326 of the Group’s Annual Report and Accounts for the year ended 31 December 2025 and pages 165 to 169 of the 2025 Form 20-F: – Level 1 financial instruments are traded in an active market and fair value is based on quoted prices at the period end. – Level 2 financial instruments are not traded in an active market, but the fair values are based on quoted market prices, broker/ dealer quotations, or alternative pricing sources with reasonable levels of price transparency. The Group’s level 2 financial instruments include OTC derivatives. – The fair values of level 3 financial instruments have been determined using a valuation technique where at least one input (which could have a significant effect on the instrument's valuation) is not based on observable market data. The Group’s level 3 financial instruments primarily consist of an equity investment in an unquoted entity, interest free loans and other treasury products which are valued using the discounted cash flows of estimated future cash flows. While the carrying values of assets and liabilities at fair value have changed since 31 December 2025, the Group does not consider the movements in value to be significant, and the categorisation of these assets and liabilities in accordance with the disclosure requirements of IFRS 7 Financial Instruments has not materially changed. The values of level 1 assets and level 3 assets are £203 million and £75 million, respectively, at 30 June 2026 (30 June 2025: £1,069 million and £157 million, respectively, and 31 December 2025: £211 million and £138 million, respectively). As disclosed in the Group's Annual Report and Accounts for the year ended 31 December 2025 and the 2025 Form 20-F, in the second half of 2025, the Group sold part of its investment in ITC Hotels and liquidated a significant portion of assets held by its Canadian business as part of exiting CCAA protection. Level 2 assets and liabilities are shown below. As at 30 June As at 31 December 2026 2025 2025 £m £m £m Assets at fair value Derivatives relating to – interest rate swaps 18 59 44 – cross-currency swaps 93 110 105 – forward foreign currency contracts 128 274 148 Assets at fair value 239 443 297 Liabilities at fair value Derivatives relating to – interest rate swaps 129 117 92 – cross-currency swaps 7 14 5 – forward foreign currency contracts 101 207 118 Liabilities at fair value 237 338 215 Borrowings are carried at amortised cost. The fair value of borrowings is estimated to be £33,503 million (30 June 2025: £33,495 million; 31 December 2025: £33,717 million). The value of other assets and liabilities held at amortised cost are not materially different from their fair values. 12. Retirement benefit schemes The Group’s subsidiary undertakings operate various funded and unfunded defined benefit schemes, including pension and post- retirement healthcare schemes, and defined contribution schemes in various jurisdictions, with its most significant arrangements in both years being in the U.S., Canada, Germany, Switzerland and the Netherlands. A buy-out process in respect of the British American Tobacco UK Pension Fund was concluded on 23 April 2026, when the liabilities of the Fund were formally extinguished, resulting in the derecognition of £1,766 million of retirement benefit scheme liabilities and an equivalent amount of scheme assets. Benefits provided through defined contribution schemes are charged as an expense as payments fall due. The liabilities arising in respect of defined benefit schemes are determined in accordance with the advice of independent, professionally qualified actuaries, using the projected unit credit method. It is Group policy that all schemes are formally valued at least every three years. The overall net asset for all pension and healthcare schemes in Group subsidiaries amounted to £132 million at 30 June 2026, compared to a net asset of £79 million at 31 December 2025 (30 June 2025: £72 million).

Notes to the Unaudited Interim Financial Statements (continued) 13. Contingent liabilities and financial commitments The Group has contingent liabilities in respect of litigation, taxes and guarantees in various countries. These are described below, are further described in Note 31 to the 2025 Annual Report and Accounts and the 2025 Form 20-F and will be included in the 2026 Annual Report and Accounts and the annual report for the year ended 31 December 2026 on Form 20-F (the "2026 Form 20-F"). The Group is subject to contingencies pursuant to requirements that it complies with relevant laws, regulations and standards. Failure to comply could result in restrictions in operations, damages, fines, increased tax, increased cost of compliance, interest charges, reputational damage or other sanctions. These matters are inherently difficult to quantify. In cases where the Group has an obligation as a result of a past event existing at the balance sheet date, it is probable that an outflow of economic resources will be required to settle the obligation and the amount of the obligation can be reliably estimated, a provision will be recognised based on best estimates and management judgement. There are, however, contingent liabilities in respect of litigation, taxes in some countries and guarantees for which no provisions have been made. While the amounts that may be payable or receivable could be material to the results or cash flows of the Group in the period in which they are recognised, the Board does not expect these amounts to have a material effect on the Group’s financial condition. Taxes The Group has exposures in respect of the payment or recovery of a number of taxes. The Group is and has been subject to a number of tax audits covering, among others, excise tax, value-added taxes, sales taxes, corporate taxes, overseas withholding taxes and payroll taxes. The estimated costs of known tax obligations have been provided in these accounts in accordance with the Group’s accounting policies. In some countries, tax law requires that full or part payment of disputed tax assessments be made pending resolution of the dispute. To the extent that such payments exceed the estimated obligation, they would not be recognised as an expense. There are disputes that are in or may proceed to litigation in a number of countries, including Brazil, the Netherlands, Indonesia and Romania. In the Netherlands, the Group has agreed with the Dutch Tax Authorities to provide a bank guarantee from 1 July 2026 for an initial amount of £105 million increasing annually over a five-year period up to £488 million, being the liability including interest arising from the September 2025 Court of Appeal judgment (as discussed on page 351 of the 2025 Annual Report and Accounts and page 189 of the 2025 Form 20-F). In June 2026, British-American Tobacco (Romania) Investment S.R.L.’s appeal against the negative decision of the administrative court in respect of the findings of the excise audit was stayed by the Ploiesti Court of Appeal until the final resolution of the legal challenge against the underlying procedural excise framework. Group litigation Group companies, as well as other leading cigarette manufacturers, are defendants in a number of product liability cases. In a number of the cases, the amounts of compensatory and punitive damages sought are significant. While it is impossible to be certain of the outcome of any particular case or of the amount of any possible adverse verdict, the Group believes that the defences of the Group’s companies to all these various claims are meritorious on both the law and the facts, and a vigorous defence is being made everywhere. If an adverse judgment is entered against any of the Group’s companies in any case, avenues of appeal will be pursued as necessary. Such appeals could require the appellants to post appeal bonds or substitute security in amounts that could in some cases equal or exceed the amount of the judgment. At least in the aggregate, and despite the quality of defences available to the Group, it is not impossible that the Group’s results of operations or cash flows in a particular period could be materially affected by this and by the final outcome of any particular litigation. Canada Following the release of the March 2019 Quebec class action judgment and the commencement of provincial healthcare recoupment actions and related tobacco litigation in Canada, JTI-MacDonald Corp, Imperial Tobacco Canada Limited (Imperial), Imperial Tobacco Company Limited (together with Imperial, ITCAN) and Rothmans, Benson & Hedges Inc. each filed for creditor protection under the Companies’ Creditors Arrangement Act (CCAA), resulting in court-ordered stays of all Canadian tobacco litigation, including litigation against: (i) ITCAN, British American Tobacco p.l.c. (the Company), British American Tobacco (Investments) Limited, B.A.T. Industries p.l.c. and Carreras Rothmans Limited; and (ii) R. J. Reynolds Tobacco Company (RJRT) and R.J. Reynolds Tobacco International Inc. (which benefit from an indemnification by Japan Tobacco International (JTI) for all liabilities and obligations arising in respect of the Canadian recoupment actions). In March 2025, the Ontario Superior Court sanctioned comprehensive settlement plans, which were implemented in August 2025 and resolved all outstanding Canadian tobacco litigation against the defendants named above, providing full releases to the relevant BAT Group companies in respect of historical tobacco-related claims in Canada. Under the settlement, participating manufacturers are required to make ongoing payments over time based on a percentage (initially 85%, reducing over time to 70%) of net income after tax based on amounts generated from all sources, excluding New Categories, until they settle the liability (CAD$32.5 billion (approximately £17.3 billion)) in full. The Group has recognised a provision reflecting management's best estimate of ITCAN's obligations under the settlement arrangements. All underlying tobacco litigation is now closed. Further information on the Canadian litigation is provided in Note 31 to the Group’s Annual Report and Accounts for the year ended 31 December 2025, pages 342 to 344, and the 2025 Form 20-F, page 182.

Notes to the Unaudited Interim Financial Statements (continued) 13. Contingent liabilities and financial commitments (continued) U.S. - Engle As at 30 June 2026, the Group’s subsidiaries, RJRT, Lorillard Tobacco Company (Lorillard Tobacco) and Brown & Williamson Holdings, Inc., had collectively been served in 21 pending Engle progeny cases filed on behalf of approximately 31 individual plaintiffs. Many of these are in active discovery or nearing trial. In the first half of 2026, RJRT or Lorillard Tobacco paid judgments in one Engle progeny case. Such payment amounted to approximately US$675,000 (approximately £499,537) in compensatory or punitive damages. Additional costs were paid in respect of attorneys' fees and statutory interest. In addition, from 1 January 2024 to 30 June 2026, outstanding jury verdicts in favour of the Engle progeny plaintiffs had been entered against RJRT or Lorillard Tobacco for US$19.6 million (approximately £14.5 million) in compensatory damages (as adjusted) and US$26.4 million (approximately £19.5 million) in punitive damages. A majority of these verdicts are in various stages in the appellate process and have been bonded as required by Florida law under the US$200 million (approximately £148.0 million) bond cap passed by the Florida legislature in 2009. Although the Group cannot currently predict when or how much it may be required to bond and pay, the Group’s subsidiaries will likely be required to bond and pay additional judgments as the litigation proceeds. Kalamazoo Georgia-Pacific, a designated Potentially Responsible Party (PRP) in respect of the Kalamazoo River in Michigan, pursued NCR Corporation in relation to remediation costs caused by PCBs released into that river. On 26 September 2013, the United States District Court, Michigan held that NCR was liable as a PRP on the basis that it had arranged for the disposal of hazardous material for the purposes of the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). Following further litigation, on 11 December 2019, NCR announced that it had entered into a Consent Decree with the U.S. Government and the State of Michigan (subsequently approved by the Michigan Court on 2 December 2020), pursuant to which it assumed liability for certain remediation work at the Kalamazoo River. The payments to be made on the face of the Consent Decree in respect of such work total approximately US$245 million (approximately £181.3 million). The Consent Decree also provides for the payment by NCR of an outstanding judgment against it of approximately US$20 million (approximately £14.8 million) to Georgia-Pacific. The quantum of the clean-up costs for the Kalamazoo River is presently unclear. It seems likely to well exceed the amounts payable on the face of the Consent Decree. On 10 February 2023, NCR filed a complaint in the United States District Court for the Southern District of New York against B.A.T. Industries P.L.C. (Industries), seeking a declaration that Industries must compensate NCR for 60% of costs NCR incurred and incurs relating to the Kalamazoo River site on the asserted basis that the Kalamazoo River constitutes a ‘Future Site’ for the purposes of a 1998 Settlement Agreement between it, Appvion and Industries. On 23 June 2023, Industries filed its defence and counterclaims in the proceedings. On 2 October 2023, NCR filed a motion for declaratory judgment on its complaint and to strike out Industries’ affirmative defences and counterclaims. Industries filed its reply to this motion. On 14 September 2024, the court issued a judgment in respect of the motion, striking out one of Industries’ eight affirmative defences and dismissing three of Industries’ five counterclaims against NCR's complaint. The proceedings are ongoing. Nahadi Litigation On 29 January 2026, a claim was filed in the U.S. District Court for the Eastern District of Virginia against the Company and British-American Tobacco Marketing (Singapore) Private Limited (BATMS). The claimants are 196 U.S. nationals and family members who claim unquantified civil damages under the U.S. Anti-Terrorism Act. The substance of the allegations relate to matters previously disclosed in relation to historical business activities in the Democratic People’s Republic of Korea which resulted in the Company’s April 2023 entry into a three-year deferred prosecution agreement (DPA) with the U.S. Department of Justice (DOJ), with BATMS pleading guilty to the same charges, and a civil settlement agreement with the U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC). At a hearing on 24 July 2026, the Court granted the defendants’ motion to dismiss the claim, which the claimants have appealed. UK Securities On 26 June 2026, a claim issued in the High Court of England and Wales under Sections 90 and 90A of the UK’s Financial Services and Markets Act 2000 was served on the Company. The claim relates to the previously disclosed investigations by the DOJ and OFAC into the group’s historical business activities in the Democratic People’s Republic of Korea. The claim is brought by current and former shareholders in the Company and names the Company as defendant. The claim alleges that the Company made untrue or misleading statements in its published information and/or dishonestly omitted or delayed publication of certain information regarding the group’s activities in the Democratic People’s Republic of Korea. The Company intends to vigorously defend the claim. Investigations On 25 April 2023, the Group announced that it had reached agreement with DOJ and OFAC to resolve previously disclosed investigations into suspicions of breaches of sanctions relating to the Democratic People’s Republic of Korea between 2007 and 2017. On 11 May 2026, DOJ filed a motion to dismiss the legal proceedings against the Company, noting that the Company fully complied with the terms of the three-year DPA, and the court entered an order dismissing the proceedings with prejudice the same day. The three-year probationary period imposed by the court on a BAT subsidiary in Singapore, BATMS, in connection with the subsidiary’s entry of a guilty plea in the same proceedings has also now expired. The Company’s compliance commitments under the civil settlement with OFAC remain in place until 2028. The Group investigates, and becomes aware of governmental authorities’ investigations into, allegations of misconduct, including alleged breaches of sanctions and allegations of corruption, at Group companies. Some of these allegations are currently being investigated, including by OFAC, which is investigating suspicions of breaches of sanctions. The Group cooperates with the authorities, where appropriate. There are instances where the Group investigates or where Group companies are cooperating with relevant national competition authorities in relation to competition law investigations and/or engaged in legal proceedings at the appellate level, including (amongst others) in Belgium and Brazil.

Notes to the Unaudited Interim Financial Statements (continued) 13. Contingent liabilities and financial commitments (continued) Investigations (continued) In addition, the Group is, and may in the future be, subject to investigations or legal proceedings in relation to, among other things, its marketing, promotion or distribution activities in respect of its products. This includes, but is not limited to, allegations that such activities, whether undertaken through traditional channels, digital platforms, third parties, or distribution applications, do not comply with applicable laws or regulations. As such, the Group or Group companies, could be subject to liability and costs associated with any damages, fines, or penalties brought in connection with these allegations. Group litigation summary Having regard to all these matters, with the exception of Canada and Fox River, the Group does not consider it appropriate to make any provision or accrual in respect of any pending litigation or governmental investigation. The Group does not believe that the ultimate outcome of any pending litigation or governmental investigation will significantly impair the Group’s financial condition. If the facts and circumstances change, then there could be a material impact on the financial statements of the Group. In addition, the Group accrues for damages, attorneys' fees and/or statutory interest, including in respect of certain Engle Progeny cases and certain U.S. individual smoking and health cases. Full details of any litigation and governmental investigation against Group companies and tax disputes as at 30 June 2026 will be included in the Annual Report and Accounts for the year ended 31 December 2026 and the 2026 Form 20-F. Whilst there has been some movement on new and existing cases against Group companies, there have been, except as otherwise stated, no material developments to date in 2026 that would impact the financial position of the Group. 14. Franked investment income litigation order The Group has been the principal test claimant in an action in the United Kingdom against HM Revenue and Customs (HMRC) in the FII GLO. There were 11 corporate groups in the FII GLO as at 30 June 2026. The case concerned the treatment for UK corporate tax purposes of profits earned overseas and distributed to the UK. Following a number of hearings (on limitation and computation) by the High Court, Court of Appeal and Supreme Court in the UK and the European Court of Justice over a number of years, which reduced the value of the Group’s claim to approximately £0.3 billion, mainly as the result of the application of simple interest, in January 2026 the Supreme Court refused HMRC permission to appeal the Court of Appeal's judgment on limitation. In February 2026, the Supreme Court decided to grant permission to appeal on the computational issue on another test case. However, the Group considers that the computational issue should not impact BAT’s claim and considers that the litigation has now reached its conclusion. During 2015, HMRC paid to the Group a gross amount of £1.2 billion in two separate payments, less a deduction (withheld by HMRC) of £0.3 billion. The payments made by HMRC were made without any admission of liability and were subject to refund if HMRC succeeded on appeal. Due to the uncertainty of the amounts and eventual outcome the Group did not recognise any impact in the income statement in prior periods in respect of the receipt (being net £0.9 billion) which was held within trade and other payables. The Group made interim payments to HMRC of £479 million in 2025 and annual payments of £50 million in each of 2024, 2023 and 2022. In 2026, the Group will repay £222 million (of which £111 million was paid in the first six months of 2026). A final payment of £43 million will be paid in 2027. However, as the Group considers that, following the judgment by the Supreme Court in the UK, the litigation has now reached its conclusion, an adjusting tax credit of £95 million and an adjusting credit to net finance costs of £315 million has been recognised in the six months ended 30 June 2026. With respect to the remaining amounts repayable to HMRC, in the six months ended 30 June 2026, the Group recognised an adjusting interest charge of £0.3 million (30 June 2025: £19 million). Information for FII GLO for 2025 was disclosed on pages 278 and 279 of the Annual Report and Accounts for the year ended 31 December 2025 and page 126 of the 2025 Form 20-F. 15. Related party disclosures The Group’s related party transactions and relationships for 2025 were disclosed on pages 332 and 333 of the Annual Report and Accounts for the year ended 31 December 2025 and pages 173 to 175 of the 2025 Form 20-F. In addition, information on Charlotte's Web was disclosed on page 293 of the Annual Report and Accounts for the year ended 31 December 2025 and page 140 of the 2025 Form 20-F. In the six months ended 30 June 2026, apart from the disposal of Brascuba (as disclosed on page 328 of the Annual Report and Accounts for the year ended 31 December 2025 and page 170 of the 2025 Form 20-F, and page 26 of this Half Year Report), the sale of Sanity to Organigram (discussed on page 27) and the investment in and collaboration with Organigram and the conversion of the Group’s loan to Charlotte’s Web Holdings into ordinary shares (see page 27), there were no material changes in related parties or related party transactions to be reported. In the six months ended 30 June 2025, apart from the partial sale of the Group's investment in ITC, the demerger of ITC's hotel business (see page 27) and the investment in and collaboration with Organigram, there were no material changes in related parties or related party transactions to be reported.

Other Information Summarised financial information The following summarised financial information is required by the rules of the Securities and Exchange Commission and has been prepared in accordance with Section 3-10 of Regulation S-X in respect of the guarantees of: – US$6.89 billion of outstanding bonds issued by B.A.T Capital Corporation (BATCAP) in connection with the acquisition of Reynolds American, including registered bonds issued in exchange for the initially issued bonds (the 2017 Bonds); – US$10.12 billion of outstanding bonds issued by BATCAP pursuant to the Shelf Registration Statement on Form F-3 filed on 17 July 2019, US$8.80 billion of outstanding bonds issued by BATCAP pursuant to the Shelf Registration Statement on Form F-3 filed on 1 July 2022 and US$750 million of outstanding bonds issued by BATCAP pursuant to the Shelf Registration Statement on Form F-3 filed on 1 July 2025 pursuant to which BATCAP, BATIF or the Company may issue an indefinite amount of debt securities; and – US$1.00 billion of outstanding bonds issued by BATIF pursuant to the Shelf Registration Statement on Form F-3 filed on 17 July 2019, and US$1.00 billion of outstanding bonds issued by BATIF pursuant to the Shelf Registration Statement on Form F-3 filed on 1 July 2022 pursuant to which BATCAP, BATIF or the Company may issue an indefinite amount of debt securities. As of 28 July 2020, all relevant Group entities suspended their reporting obligations with respect to the US$4.65 billion (30 June 2025 and 31 December 2025: US$4.65 billion) of RAI unsecured notes and US$22.12 million (30 June 2025 and 31 December 2025: US$22.12 million) of Lorillard unsecured notes. As such, no summarised financial information is provided with respect to these securities. The SEC Shelf registration was renewed in July 2025 and is valid for three years. As described below, Reynolds American Inc. (Reynolds American/RAI) is a subsidiary guarantor of all outstanding series of BATCAP and BATIF bonds. Under the terms of the indentures governing such notes, any subsidiary guarantor (including Reynolds American) other than BATCAP or BATIF, as applicable, BATNF and BATHTN (as defined below), will automatically and unconditionally be released from all obligations under its guarantee, and such guarantee shall thereupon terminate and be discharged and of no further force or effect, in the event that (1) its guarantee of all then outstanding notes issued under the Group’s EMTN Programme is released or (2) at substantially the same time its guarantee of the debt securities is terminated, such subsidiary guarantor is released from all obligations in respect of indebtedness for borrowed money for which such subsidiary guarantor is an obligor (as a guarantor or borrower). Under the EMTN Programme, Reynolds American’s guarantee is released if at any time the aggregate amount of indebtedness for borrowed money, subject to certain exceptions, for which Reynolds American is an obligor, does not exceed 10% of the outstanding long-term debt of BAT as reflected in the balance sheet included in BAT's most recent publicly released interim or annual consolidated financial statements. Reynolds American’s guarantee may be released notwithstanding Reynolds American guaranteeing other indebtedness, provided Reynolds American’s guarantee of outstanding notes issued under the EMTN Programme is released. If Reynolds American’s guarantee is released, BAT is not required to replace such guarantee, and the debt securities will have the benefit of fewer subsidiary guarantees for the remaining maturity of the debt securities. Note: The following summarised financial information reports the unconsolidated contribution of each applicable company to the Group’s consolidated results and not the separate financial statements for each applicable company as local financial statements are prepared in accordance with local legislative requirements and may differ from the financial information provided below.

Other Information (continued) Non-financial Key Performance Indicators (KPIs) Volume The Group reports volumes as additional information. This is done, where appropriate, with cigarette sticks as the basis, with usage levels applied to other products to calculate the equivalent number of cigarette units. Volume is defined as the number of units sold. Units may vary between categories. The conversion rates that are applied: Equivalent to one cigarette Factory-made cigarettes (FMC) 1 stick Heated sticks 1 heat stick Cigars 1 cigar (regardless of size) Oral – Pouch 1 pouch – Moist Snuff 2.8 grams – Dry Snuff 2.0 grams – Loose leaf, plug, twist 7.1 grams Pipe tobacco 0.8 grams Roll-your-own 0.8 grams Make-your-own – Expanded tobacco 0.5 grams – Optimised tobacco 0.7 grams Vapour No conversion to a stick equivalent Roll-your-own (RYO) Loose tobacco designed for hand rolling, normally a finer cut with higher moisture, compared to cigarette tobacco. Make-your-own (MYO) MYO expanded tobacco; also known as volume tobacco. Loose cigarette tobacco with enhanced filling properties – to allow higher yields of cigarettes/kg - designed for use with cigarette tubes and filled via a tobacco tubing machine. MYO non-expanded tobacco; also known as optimised tobacco Loose cigarette tobacco designed for use with cigarette tubes and filled via a tobacco tubing machine. Vapour Vapour is shown in units being pods, bottles and disposable units. There is no conversion to a stick equivalent. Volume share Volume share is the estimated number of units bought by adult consumers of a specific brand or combination of brands, as a proportion of the total estimated units bought by adult consumers in the industry, category or other sub-category. Sub- categories include, but are not limited to, HP, Modern Oral, Traditional Oral, Total Oral or Cigarettes. Except when referencing particular markets, volume share is based on our Top markets. Top markets are those markets that management determines are strategic in each category, with reliable share data from third parties. Management notes that the markets that form the definition of Top markets may change between periods as this will reflect the development of the category within markets including their relative revenue sizes. Please refer to page 46 for a list of the Top markets. Where possible, the Group utilises data provided by third-party organisations, including NielsenIQ, based upon retail audit of sales to adult consumers. In certain markets, where such data is not available, other measures are employed which assess volume share based upon other movements within the supply chain, such as sales to retailers. This may depend on the provision of data by customers including distributors/wholesalers. Volume share is used by management to assess the relative performance of the Group and its brands against the performance of its competitors in the categories and geographies in which the Group operates. Management notes that this measure is useful to investors to understand the relative performance of the Group and its brands against the performance of its competitors in the categories and geographies in which the Group operates. This measure is also useful to understand the Group’s performance when seeking to grow scale within a market or category from which future financial returns can be realised. Volume share provides an indicator of the Group’s relative performance in unit terms versus competitors. Volume share in each period compares the average volume share in the period with the average volume share in the prior year (using the current period Top markets). This is a more robust measure of performance, removing short-term volatility that may arise at a point in time. Due to the timing of available information, volume share for 2026 is year-to-date May 2026 unless otherwise stated. However, in certain circumstances, related to periods of introduction to a market, in order to illustrate the latest performance, data may be provided as at the end of the period rather than the average in that period. In these instances, the Group states these at a specific date (for instance, May 2026).

Other Information (continued) Non-financial Key Performance Indicators (KPIs) (continued) Value share Value share is the estimated retail value of units bought by adult consumers of a particular brand or combination of brands, as a proportion of the total estimated retail value of units bought by adult consumers in the industry, category or other sub-category in discussion. Except when referencing particular markets, value share is based on our Top markets. Top markets are those markets that management determines are strategic in each category, with reliable share data from third parties. Management notes that the markets that form the definition of Top markets may change between periods as this will reflect the development of the category within markets including their relative revenue sizes. Please refer to page 46 for a list of the Top markets. Where possible, the Group utilises data provided by third-party organisations, including NielsenIQ, based upon retail audit of sales to adult consumers. In certain markets, where such data is not available, other measures are employed which assess value share based upon other movements within the supply chain, such as sales to retailers. This may depend on the provision of data by customers (including distributors and wholesalers). Value share is used by management to assess the relative performance of the Group and its brands against the performance of its competitors in the categories and geographies in which the Group operates, specifically indicating the Group’s ability to realise value relative to the market. The measure is particularly useful when the Group’s products and/or the relevant category in the market in which they are sold has developed or achieved scale from which value can be realised. Management notes that this measure is useful to investors to comprehend the relative performance of the Group and its brands against the performance of its competitors in the categories and geographies in which the Group operates, specifically indicating the Group’s ability to realise value relative to the market. Value share in each period compares the average value share in the period with the average value share in the prior year (using the current period Top markets). This is a more robust measure of performance, removing short-term volatility that may arise at a point in time. Due to the timing of available information, value share for 2026 is year-to-date May 2026 unless otherwise stated. However, in certain circumstances, related to periods of introduction to a market, in order to illustrate the latest performance, data may be provided as at the end of the period rather than the average in that period. In these instances the Group states these at a specific date (for instance, May 2026). Price/mix Price/mix is a term used by management and users of the financial statements to explain the movement in revenue between periods. Revenue is affected by the volume (how many units are sold) and the value (how much is each unit sold for). Price/mix is used to explain the value component of the sales as the Group sells each unit for a value (price) but may also achieve a movement in revenue due to the relative proportions of higher value volume sold compared to lower value volume sold (mix). This term is used to explain the Group’s relative performance between periods only. It is calculated as the difference between the movement in revenue (between periods at constant rates of exchange) and volume (between periods). For instance, in the six months to June 2026 (compared to the same period in the prior year) the increase in combustibles revenue (excluding translational foreign exchange movements) of 2.1%, with a decline in combustibles volume of 4.7%, leads to a price/mix (including excise duty drawback) of 6.8%. No assumptions underlie this metric as it utilises the Group’s own data. We also show (see page 3) the impact on revenue from the movement in combustibles volume (being the movement in volume between periods multiplied by the average combustibles revenue per thousand from the prior period) and the impact from the combustibles price/mix effect (see page 3), which is revenue (from combustibles at constant rates) less the volume effect from the movement in combustibles. Consumers of Smokeless products The number of consumers of Smokeless products is defined as the estimated number of Legal Age (minimum 18 years) consumers of the Group’s Smokeless products - which does not necessarily mean these users are solus consumers of these products. In markets where regular consumer tracking is in place, this estimate is obtained from adult consumer tracking studies conducted by third parties (including Kantar). In markets where regular consumer tracking is not in place, the number of consumers of Smokeless products is derived from volume sales of consumables and devices in such markets, using consumption patterns obtained from other similar markets with adult consumer tracking (utilising studies conducted by third parties, including Kantar). The number of consumers is adjusted for those identified (as part of the consumer tracking studies undertaken) as using more than one BAT Brand – referred to as “poly users”. The number of Smokeless products consumers is used by management to assess the number of consumers using the Group’s New Categories products as the increase in Smokeless products is a key pillar of the Group’s sustainability ambition and is integral to the sustainability of our business. The Group’s Management Board believes that this measure is useful to investors given the Group’s sustainability ambition and alignment to the sustainability of the business with respect to the Smokeless portfolio. Periodically, in line with standard practice, enhancements to the adult consumer tracking studies may be required to more accurately capture market trends across categories and as markets perform with respect to the development of the categories. When a change is applied, to ensure that the data is comparable between periods, historical data will be back-trended to ensure there is no trend break. During 2026, Kantar made enhancements to their adult consumer tracking studies in a number of markets in Europe and back- trended the data accordingly. However, in aggregate, there was no change to the previously reported totals provided below. 2025 2024 As previously reported 34.1 29.4 BAT Interim Announcement 2026 Summary Performance Review Financial Statements Other Information Data Lake and Reconciliations 41

These statements are often, but not always, made through the use of words or phrases such as "believe," "anticipate," "could," "may," "would," "should," "intend," "plan," "potential," "predict," "will," "expect," "estimate," "project," "positioned," "strategy," "outlook," "target," "being confident" and similar expressions. These include statements regarding our intentions, beliefs or current expectations concerning, amongst other things, our results of operations, financial condition, liquidity, prospects, growth, strategies and the economic and business circumstances occurring from time to time in the countries and markets in which the British American Tobacco Group (the “Group”) operates. All such forward-looking statements involve estimates and assumptions that are subject to risks, uncertainties and other factors. It is believed that the expectations reflected in this announcement are reasonable, but they may be affected by a wide range of variables that could cause actual results and performance to differ materially from those currently anticipated. Among the key factors that could cause actual results to differ materially from those projected in the forward-looking statements are uncertainties related to the following: the impact of increased competition from illicit trade and illegal products; changes or differences in domestic or international economic or political conditions; the impact of adverse domestic or international legislation and regulation of tobacco, New Categories and other regulation; the impact of supply chain disruptions; adverse litigation and external investigations and dispute outcomes and the effect of such outcomes on the Group’s financial condition; the impact of significant increases or structural changes in tobacco, nicotine and New Categories related taxes; the inability to develop, commercialise and deliver the Group’s New Categories strategy; adverse decisions by domestic or international regulatory bodies, including disputed taxes, interest and penalties; the impact of serious injury, illness or death in the workplace and those who work with the business; the ability to maintain credit ratings and to fund the business under the current capital structure; translational and transactional foreign exchange rate exposure; direct and indirect adverse impacts associated with climate change (both physical and transition); the ability to deliver a viable circular business model in response to global demand, combined with increasing regulatory, stakeholder and consumer pressure; and the Group’s ability to defend against Cyber & Digital actions that result in loss of confidentiality, availability or integrity of systems and data. A review of the reasons why actual results and developments may differ materially from the expectations disclosed or implied within forward-looking statements can be found by referring to the information contained under the headings “Cautionary statement” and "Group Principal Risks" in the Group's 2025 Annual Report and Accounts and "Forward looking statements" and "Item 3.D - Risk factors" in the 2025 Form 20-F.

The Group’s management regularly reviews the measures used to assess and present the financial performance of the Group and, as relevant, its geographic segments. The following table demonstrates the principal non-GAAP measures which the Group uses and indicates the IFRS measure from which each principal Non-GAAP measure is reconciled from: Non-GAAP Measure title Presented in Reconciled from: Current rates Constant rates Adjusted for Canada2 IFRS measure Revenue £m n/a1 Yes Revenue New Categories revenue £m Yes Yes Revenue Smokeless revenue as a % of total revenue % Yes Revenue Adjusted gross profit £m Yes Yes Profit from Operations Adjusted gross margin % Yes Yes Revenue/Profit from Operations Category contribution £m Yes Yes Profit from Operations Category contribution margin % Yes Yes Revenue/Profit from Operations Adjusted profit from operations £m Yes Yes Yes Profit from Operations Adjusted operating margin % Yes Yes Yes Revenue/Profit from Operations Adjusted diluted earnings per share p Yes Yes Yes Diluted Earnings per Share Adjusted net debt £m Yes Yes Borrowings Operating cash conversion % Yes Net cash generated from operating activities Adjusted cash generated from operations £m Yes Yes Net cash generated from operating activities Free cash flow before and after dividends paid to shareholders £m Yes Net cash generated from operating activities The Group also uses adjusted share of post-tax results of associates and joint ventures, adjusted net finance costs, adjusted taxation and underlying tax rate. The Management Board, as the chief operating decision-maker, reviews a number of our IFRS and non-GAAP measures for the Group and geographic segments and its product categories at constant rates of exchange. This allows comparison of the Group’s results, had they been translated at the previous year’s average rates of exchange. The Group does not adjust for the normal transactional gains and losses in profit from operations that are generated by exchange movements. Non-GAAP measures also include measures excluding the impact of adjusting items. Although the Group does not believe that these measures are a substitute for IFRS measures, the Group does believe such results excluding the impact of adjusting items and currency fluctuations that may significantly affect the users' understanding of the Group's performance when compared across period, as applicable, provide additional useful information to users of the financial statements regarding the underlying performance of operating performance on a local currency basis (see page 12) and the business on a comparable basis. Adjusting items, used to calculate certain of the above measures, are identified in accordance with the Group’s accounting policies. They represent certain items of income and expense which the Group considers distinctive based on their size, nature or incidence and which individually or, if of a similar type, in aggregate, are relevant to an understanding of the Group’s underlying financial performance. As the Chief Operating Decision Maker, the Management Board assesses the performance of the Group by reviewing adjusted profit from operations as adjusted for Canada2 (to evaluate segment performance and allocate resources to the overall business on a regional basis) and adjusted diluted EPS as adjusted for Canada2, both using the prior year translational exchange rate (constant rate). These measures recognise a charge calculated in line with the Approved Plans as agreed in 2025 – based on a percentage of Imperial Tobacco Canada Limited's and Imperial Tobacco Company Limited's (together, ITCAN) net income after taxes from all sources in Canada, excluding New Categories. This charge will continue until the aggregate settlement amount is paid. This is reflected in the adjusted performance of the Group and is referred to as “as adjusted for Canada”. Management believes that these measures present the economic delivery from the AME region in a manner comparable to that of the other regions in the Group. 1. Revenue at current rates is the IFRS measure. 2. The adjustment in respect of Canada is based upon a percentage (2026: 85%; 2025: 100%) of the net income after taxes earned from all sources, excluding New Categories, in Canada. BAT Interim Announcement 2026 Summary Performance Review Financial Statements Other Information Data Lake and Reconciliations 47

Data Lake and Reconciliations Continued Non-GAAP measures (continued) In 2025, due to the uncertain nature of the timing of the implementation of the settlement on the Group’s 2025 results this charge was 100% of the net income after taxes earned from all sources in Canada, excluding New Categories. From 2026, this charge (following the underlying terms of the Approved Plans) is 85% of the net income after taxes earned in Canada from all sources, excluding New Categories, reducing in future periods in line with the Approved Plans. In 2025, the Group recognised an adjusting charge in net finance costs in respect of interest earned on the restricted cash held in Canada that was paid as part of the upfront settlement payment. This was adjusted out in 2025 as the interest income was not representative of the ongoing business. Additionally, the Group uses the non-GAAP measures of non-controlling interest, coupons relating to hybrid bonds net of tax and profit attributable to shareholders. Breakdowns of revenues by product category (including revenue generated from Vapour, Heated Products, Modern Oral, New Categories as a whole, Traditional Oral, Smokeless products as a whole and combustibles) and by geographic segment (including revenue generated in the United States, Americas and Europe and Asia-Pacific, Middle East and Africa), contributions to profit from operations by product category, adjusted gross profit, adjusted gross margin, category contribution, category contribution margin, adjusted profit from operations, adjusted operating margin, adjusted net finance costs, adjusted group share of post-tax results of associates and joint ventures, adjusted taxation, underlying taxation, adjusted diluted earnings per share, free cash flow (before dividends paid to shareholders), free cash flow (after dividends paid to shareholders), adjusted cash generated from operations, operating cash conversion ratio, net debt, adjusted net debt (including, where appropriate, presented as adjusted for Canada)1 have limitations as analytical tools. They are not presentations made in accordance with IFRS and none of these non-GAAP measures should be considered as an alternative measure of revenue, profit from operations, cash flows or any financial measure based thereon, as applicable, determined in accordance with IFRS. These measures demonstrate, among other things, the Group's profitability (before adjusting items and translational foreign exchange) from the principal product categories, illustrating the category profitability development as the Group realises the transition from combustibles to Smokeless products in line with the Group's strategy to Build a Smokeless World. The Group’s Management Board believes these measures, which are used internally, are useful to the users of the financial statements in helping them understand the underlying business performance and can provide insights into the cash flow available to, among other things, reduce debt and pay dividends. None of these non-GAAP measures are necessarily comparable to similarly titled measures used by other companies. As a result, readers should not consider these non-GAAP measures in isolation from, or as a substitute analysis for, the Group’s revenue, profit from operations, cash flows or any financial measure based thereon, as applicable, as determined in accordance with IFRS. Due to the secondary listing of the ordinary shares of British American Tobacco p.l.c. on the main board of the JSE in South Africa, the Group is required to present headline earnings per share and diluted headline earnings per share, as alternative measures of earnings per share, calculated in accordance with Circular 1/2023 ‘Headline Earnings’ issued by the South African Institute of Chartered Accountants. These are shown on page 29. 1. The adjustment in respect of Canada is based upon a percentage (2026: 85%; 2025: 100%) of the net income after taxes earned from all sources, excluding New Categories, in Canada.
