British American Tobacco (BTI -0.51%) stock climbed Thursday after the company published preliminary results for its recently completed fiscal year. The company's share price closed out the daily session up 6.8%, according to data from S&P Global Market Intelligence.

Sales in the annual period were down 1.3% to 27.3 billion British pounds but would have been up 3.1% on an organic basis assuming constant-currency rates. While revenue for the company's combustibles segment climbed 0.6% on a constant-currency basis, it was progress outside of the cigarette business that really stood out.

Sales for the company's new categories segment, which includes vapes, heated-tobacco products, and oral tobacco products, were up 21% on a currency-adjusted basis. The segment also shifted into profitability on a full-year basis, achieving that feat two years ahead of the company's initial target.

The company also announced that it would be raising its dividend 2%. While that hike comes in below the rate of inflation over the last year, the stock is still yielding roughly 9.2% at today's prices. Should investors be buying this high-yield dividend stock?

Is British American Tobacco stock a buy right now?

British American Tobacco has set a target for non-combustibles products to account for 50% of its overall revenue by 2035. That goal signals a massive shift in the company's sales by category, but it looks like the business is making some encouraging progress toward that goal.

With shares at current levels, the big risk here continues to be regulatory uncertainty. Both the combustibles segment and vapes and other alternative products within the new categories segment could face new legislative or judicial roadblocks that meaningfully weaken performance.

On the other hand, some of that risk is already priced in. With the company trading at roughly 6.7 times this year's expected earnings and paying a large dividend, British American Tobacco stock looks like a powerful passive-income generator trading at a non-prohibitive price.

The proposition isn't as cut and dried as a quick look at the company's current income generation and dividend payout would suggest, but the overall value profile appears to be worthwhile. With key impairment charge issues and patent disputes now settled and the business making progress outside of combustibles, the stock still looks cheap.
