Balfour Beatty (LSE:BBY) has agreed to sell its 50% interest in Hong Kong contractor Gammon Construction to Jardine Matheson for £250m in cash, payable in three instalments by the end of 2028.
The disposal marks a significant strategic shift for the UK construction giant, which is concentrating its exposure on core US and UK infrastructure businesses under its Evolve, Energise and Explore plan.
Gammon’s results will be reported as discontinued operations in Balfour Beatty’s 2026 accounts, formally drawing a line under the company’s long-running presence in the Hong Kong construction market.
The Gammon exit arrives during a soft patch for the BBY share price, which is down 5.37% over the past week and 4.61% over the past three months.
Despite the near-term softness, the year-to-date share price return stands at 15.90%, while the five-year total shareholder return has reached an impressive 264.99%.
That long-term momentum suggests underlying confidence in Balfour Beatty’s core infrastructure proposition, even as investors reassess the risk profile of the newly refocused business.
Balfour Beatty closed at £8.28, while the most followed narrative on the stock pegs fair value at £9.13, implying a modest undervaluation that hinges on politics, regulation, and long-dated infrastructure work.
According to PittTheYounger, this valuation view leans heavily on the idea that regulatory loosening and higher public spending could support a long runway of major projects, while the business holds margins around a 3.5% level and discounts future cash flows at 10%.
Cash from the Gammon disposal may give Balfour Beatty additional financial flexibility to pursue the kind of UK and US infrastructure work that narrative backers see as the main driver behind their £9.13 fair value estimate.
Balfour Beatty has built a broad footprint across the UK, with a presence spanning road infrastructure, public buildings, and the facility management of defence installations, alongside a substantial US operation.
Still, the company’s investment case hinges on political follow-through and disciplined project execution, and any stumble on either front could quickly puncture the 9% undervaluation argument.
Investors watching BBY will need to weigh the near-term uncertainty created by the business mix reshuffle against the potential longer-term benefits of a sharper focus on higher-margin domestic and US infrastructure markets.
