The third-quarter update from Bunzl (LSE:BNZL) on 20 October delivered firmer sales but left investors unconvinced, with the shares falling as much as 5% on the day. For income investors, the question is whether a distributor with one of the longest Dividend growth records in the FTSE 100 can keep that streak alive while its Margin outlook stays subdued. The answer depends on how the dividend, the buyback and acquisitions compete for the same cash.

A dividend record built on consistency

As of 7 October 2026, Bunzl's annual dividend stands at 74.1p per share, with the latest interim payment at 20.8p. The trailing 12-month Yield is 2.8%, and the indicated yield, which looks at the current run rate of payments, is also 2.8%.

The more striking numbers concern longevity. Bunzl has paid dividends for 42 consecutive years and has increased them for 20 years in a row. Few London-listed companies can point to a growth streak of that length, and it has spanned several recessions, a Pandemic and repeated swings in the cost of the products Bunzl distributes.

Yet the most recent increase was very small. Dividend growth year on year was just 0.3%, which keeps the streak intact but barely. An income investor relying on rising payouts would have seen almost no real-terms gain from that rise once Inflation is taken into account. The size of the increase is a clear change from the more generous steps of earlier years, and it is the main reason the length of the streak is now being questioned as much as celebrated.

Cover looks comfortable

The Payout Ratio of 49.3% means Bunzl is distributing roughly half of its earnings, leaving the dividend covered about twice. That is a comfortable position for a Business of this type, and it suggests the slowdown in dividend growth is more a matter of board caution than of any strain on affordability. Cover is calculated by dividing Earnings by the dividend, so a ratio near 50% leaves half of each pound of profit available for other uses.

It also leaves room for other uses of cash. Bunzl announced a £500 million share buyback at the half-year stage, and the October update said about £225 million of that had been completed. Buybacks reduce the share count, which can support future dividend growth per share even if the total amount paid out rises only slowly.

Management also continues to prioritise bolt-on deals, completing the purchase of Blueleaf Care, a UK distributor of care and nursing home products with 2025 Revenue of £58 million, in October.

What the October update changed

Group revenue rose 3.1% at constant exchange rates in the three months to 30 September, with underlying revenue up 3.7%. North America Distribution was a solid contributor, and acquisitions added 0.4%, while fewer trading days took away 1.1%. Fewer trading days is a reminder that quarterly revenue can move for calendar reasons alone, which is why the company quotes both constant-currency and underlying growth. Underlying revenue strips out the effect of acquisitions and trading days, giving a cleaner view of demand, and at 3.7% it was ahead of the reported figure.

The disappointment lay in what did not change, namely the outlook for profitability. Bunzl reiterated its full-year outlook of modest underlying revenue growth and a group Operating Margin broadly flat on the 7.6% recorded in 2025, excluding a share-based payment credit. That implies a year-on-year margin decline in the second half, after an improvement of around 40 basis points in the first six months.

Operating margin matters to the dividend because Bunzl is a distributor. It buys products such as packaging, gloves and cleaning supplies from manufacturers and sells them on to businesses, earning a thin margin on a very large Volume of sales. Small changes in margin therefore have a disproportionate effect on profit and, in turn, on the cash available to pay shareholders.

Reading the income case

Taken together, the figures describe a dividend that appears secure but is no longer growing with much vigour. A yield of 2.8% is modest by the standards of many FTSE 100 income stocks, so the appeal has historically rested on steady compounding. A rise of 0.3% does little for that argument, and the board's next decision will show whether it was a temporary pause or a new, slower pace.

The business model offers some reassurance. Customers buy consumables they need to keep operating, which tends to make Demand resilient, and a broad supplier and customer base spreads risk. Bunzl also operates across many countries and product categories, so weakness in one region or line can be offset elsewhere. Acquisitions add to revenue in a market where many small distributors remain independent. The risk is that integration of deals, product price swings and weaker volumes could weigh on margins for longer than expected.

For holders of LSE:BNZL, the practical trade-off is between a modest but dependable Cash Dividend and a share count that is shrinking through buybacks. Both support per-share returns, but only one puts money directly in the investor's account, which matters most to those who rely on the income to meet regular spending needs.

What to watch

The key test is the full-year results, when the board will set the final dividend and decide whether to extend the growth record to a 21st year. Investors will also watch whether second-half margins land where guidance implies, how far the remaining buyback progresses, and whether further acquisitions lift revenue without diluting profitability.

Another point of interest will be how the board describes its priorities for capital. Any language that links the next dividend decision to earnings per share, rather than to a fixed progression, would indicate how much importance LSE:BNZL places on the length of its growth run when margins are under pressure.
