† Our vapour product Vuse (including Alto, Solo, Ciro and Vibe), and certain products, including Velo, Grizzly, Kodiak, and Camel Snus, which are sold in the U.S., are subject to FDA regulation and no reduced-risk claims will be made as to these products without agency clearance.

¹��The number of consumers of Non-Combustible products is defined as the estimated number of Legal Age (minimum 18 years, U.S.: 21 years) consumers of the Group's Non-Combustible 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 Non-Combustible 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 ����̽��Brand - referred to as “poly users”. Target market for acquisition is existing adult smokers/nicotine users.

The number of consumers of Non-Combustible products is used by management to assess the number of consumers regularly using the Group's New Category products as the increase in Non-Combustible products is a key pillar of the Group's ESG ambition and is integral to the sustainability of our business.

The Group's management believes that this measure is useful to investors given the Group's ESG ambition and alignment to the sustainability of the business with respect to the Non-Combustibles portfolio.

⁶��To supplement the Group’s results presented in accordance with International Financial Reporting Standards (IFRS), the Group’s Management Board, as the chief operating decision maker, reviews certain of its results, including volume, revenue, adjusted profit from operations and adjusted operating margin, at constant rates of exchange, prior to the impact of businesses sold or held-for-sale. Although the Group does not believe that these measures are a substitute for IFRS measures, the Group does believe that such results excluding the impact of businesses sold or to be held-for-sale provide additional useful information to investors regarding the underlying performance of the business on a comparable basis and in the case of the expected sale of the Group’s businesses in Russia and Belarus, the impact these businesses have on revenue and profit from operations. Accordingly, the organic financial measures appearing in this document should be read in conjunction with the Group’s results as reported under IFRS. We also provide in this release the reconciliations of volume to organic volume, revenue to organic revenue at constant rates of exchange, profit from operations to organic adjusted profit from operations at constant rates of exchange and operating margin to organic adjusted operating margin at constant rates of exchange. In 2021, the Group sold its Iranian business. However, as the Iranian business was not significant to the user’s understanding of that year’s or subsequent years’ financial performance, management did not treat the sale of Iranian business as an organic adjustment.

Note on Non-GAAP Measures

��

The Group’s Management Board regularly reviews the measures used to assess and present the financial performance of the Group and, as relevant, its geographic segments, and believes that these measures provide additional useful information to investors. Certain of our measures are presented based on an adjusted basis and on a constant currency basis. Please refer to the 2022 Annual Report on Form 20‐F for a full description of each measure alongside non-financial measures, pages 322 to 336.

One non-GAAP measure which the Group uses and that is contained in this announcement is adjusted diluted earnings per share which is before the impact of adjusting items and is derived from diluted earnings per share. This announcement also contains operating cash conversion, a non-GAAP measure defined as net cash generated from operating activities before the impact of adjusting items and dividends from associates and excluding trade loans to third-parties, pension short fall funding, taxes paid and after net capital expenditure, as a proportion of adjusted profit from operations.

Adjusting items, as identified in accordance with the Group’s accounting policies, represent certain items of income and expense which the Group considers distinctive based on their size, nature or incidence. These include significant items in, profit from operations, net finance costs, taxation and the Group’s share of the post‐tax results of associates and joint ventures which individually or, if of a similar type, in aggregate, are relevant to an understanding of the Group’s underlying financial performance. 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 provide additional useful information to investors regarding the underlying performance of the business on a comparable basis.

The Group’s Management Board reviews a number of our IFRS and non‐GAAP measures for the Group and its geographic segments 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 operations that are generated by exchange movements. Although the Group does not believe that these measures are a substitute for IFRS measures, the Group does believe that such results excluding the impact of currency fluctuations year‐on‐year provide additional useful information to investors regarding the operating performance on a local currency basis.
