British American Tobacco shows strong cash flow and undervaluation despite UK tobacco age law changes.

British American Tobacco (BTI) maintains stable revenue and strong cash flow margins despite regulatory challenges like the UK raising the legal tobacco purchase age annually from 2027. The company benefits from loyal customers and successful growth in nicotine alternatives, which now make up 18% of sales, offsetting declines in traditional tobacco. BTI's valuation appears undervalued with an estimated equity value of £142 billion compared to its market cap of about £140 billion. This positions BTI as an attractive investment amid shifting regulations and market dynamics favoring nicotine alternatives over smoking.
