The FTSE 100’s Howden Joinery just made a bold move — should investors care?

Howden Joinery (LSE: HWDN) is among the FTSE 100’s top performers today (3 June) after agreeing to acquire online kitchen retailer DIY Kitchens in a £390m deal.

The move marks an unusual step for the group, which has long been known for its trade-only business model serving builders and contractors through its nationwide depot network.

At first glance, it’s a straightforward bolt-on acquisition of a profitable, fast-growing business.

But the more interesting question is why Howdens is making this move now, and what it reveals about how the group sees its long-term growth opportunity.

Deal mechanics

The group has agreed to acquire DIY Kitchens for an enterprise value of £390m, comprising £292.5m in cash and £97.5m in new Howdens shares. The online kitchens business operates a vertically integrated, made-to-order model focused on direct-to-consumer sales, supported by strong manufacturing capability and low overheads.

The deal values the business at around 8.5x forecast EBITDA (earnings before income, tax, depreciation and amortisation) to March 2026. Management expects the acquisition to be immediately accretive to revenue, EBIT margin and earnings per share, with strong cash generation and returns above the cost of capital.

Importantly, the transaction is being funded without materially weakening the balance sheet. Howdens will use existing cash resources alongside a new £240m bank facility, while also issuing new shares as part of the consideration.

Even after completion, the group expects to remain in a net cash position, with no change to its £100m share buyback programme for 2026 or its broader capital allocation priorities.

Strategic rationale

The key question is why Howdens is making this move now, particularly given the uncertain backdrop for UK housing and repair, maintenance and improvement (RMI) demand.

Part of the answer lies in the quality of what it’s buying. DIY Kitchens isn’t a turnaround story but a fast-growing, vertically integrated online business, with revenue growth of more than 17% a year over the past five years and EBIT margins of around 27%. It generates strong cash flow, supported by customer prepayments and a low-fixed-cost model.

The valuation also matters. At around 8.5x EBITDA, the deal looks relatively modest for a business with this level of profitability and growth. That allows Howdens to deploy capital into a higher-return asset while maintaining a strong balance sheet and continuing its buyback programme.

Just as importantly, the acquisition gives exposure to a different part of the market — direct-to-consumer demand — without disrupting its existing trade-only model. Rather than replacing its core business, this appears to be an incremental expansion into an adjacent channel that it has previously left untouched.

Measured expansion

There are still clear uncertainties. How DIY Kitchens performs once integrated alongside Howdens’ core trade model remains to be seen, particularly given the very different customer base and route to market. The broader UK housing and RMI backdrop also remains cyclical, which could affect demand across both businesses if conditions weaken further.

For now, this looks less like a transformational bet and more like a measured expansion of an already highly profitable model. While investors will want to hear more about management’s long-term ambitions, the acquisition appears strategically sensible and reinforces my view that Howdens remains a FTSE 100 stock worth researching more closely.
