Kier

Where we land

Kier is a British contractor that earns almost all of its money from building and engineering work paid for by central government and by regulated utilities. Since 2022 it has more than doubled its operating profit, the profit left after the costs of running the business, to 145m. It now holds more cash than debt, a meaningful turn for a company that spent years repairing its finances. The difficulty is the price: the shares trade at 21 times earnings against peers nearer 12 times, so much of that recovery already looks recognised by the market.

We award Kier gold. Judged only against other industrial-services companies it rates silver, because its neighbours in that group are rated even more highly. The gold reflects a business that has rebuilt itself into something steadier; the silver reflects how crowded the top of its own group is.

What the business is

Kier is close to a single business. Infrastructure and building construction accounts for 99% of its sales, covering roads, rail, schools, prisons, hospitals and defence sites. The remaining sliver is a property arm that develops and sells commercial and mixed-use buildings. That balance has not shifted, and the construction line has grown its sales by 29% since July 2023, steadily across roughly three years rather than in one leap.

Contracting is a thin-margin trade. Of every pound of sales, about 9% is left after the direct costs of doing the work, the gross margin. Once the cost of running the company is taken out, about 3% remains as operating profit. A contractor at those levels lives or dies on pricing each job correctly.

What stands out is how steady that first margin has been: over five years it has sat around 8%, barely moving either side. That suggests contracts priced and run with some discipline, rather than a history punctuated by loss-making surprises.

Why now

The case today rests on a long pipeline of public and regulated work. Kier sits on long-term frameworks, standing agreements under which government bodies and utilities hand out a stream of jobs over several years. Because that work is funded by central government and regulated utilities, it gives the company years of visible workload rather than a scramble for each next contract.

Analysts have been moving in one direction: four upward revisions to their forecasts in the last 45 days and no cuts. The people closest to the numbers see the workload turning into profit at least as well as they expected.

Kier joined our Gold Income 10 portfolio this month, which weights dividends heavily, and that fits a company whose story is shifting from repair towards returning cash.

The case for

The plainest argument is the profit record. Operating profit rose from 67m in the year to June 2022 to 145m in the year to June 2026, rising in every year along the way. Net profit, what is left for shareholders after interest and tax, climbed from 13m to 62m. That is a steady staircase, not one good year flattering the picture.

Sales have done their part without heroics, compounding at 8.8% a year over three years, so profit has grown much faster than revenue. That is the pattern of a business spreading its overheads over more work and taking fewer losses on bad jobs, an improvement that can persist as long as the workload holds.

The forecasts back this up. Consensus expects earnings per share to rise about 8% next year, and Kier's growth record relative to the wider market has improved over the past six months, with the sharpest step on 3 March 2026.

Where the growth could come from

The core driver is the steady flow of public infrastructure and building work under long-running frameworks. Sales rose 7% last year. No single recent event explains the upward revisions to forecasts; the pattern fits a business simply working through a large, secured order book.

The most likely next leg is water. UK water companies are in a regulated five-year period of sharply higher investment in pipes, treatment works and storm overflows, and Kier is one of their contractors. Our figures do not show how much of the construction line is water work, but if spending ramps as the regulated plans intend, it could lift growth above Kier's recent pace for several years and tilt the mix towards longer, lower-risk contracts. The thing to look for is rising water revenue without delays caused by the utilities' own financial strain.

Further out sits nuclear and grid work. New nuclear construction and the build-out of the UK electricity grid create demand for civil engineers with a record on large regulated projects. This is probably a small part of the business today, but these are multi-year, high-value programmes that could extend the order book well into the next decade. Named contract awards, and power appearing as a distinct contributor in Kier's results, would show it becoming real.

Equally important for the shares is the shift from repair job to cash returner: generating cash, lifting margins and handing money back through dividends and buybacks. Buying back shares means each remaining share claims a larger slice of profit, so earnings per share can grow faster than profit itself.

The property arm, at 0.9% of revenue, is a small extra rather than an engine. Well-timed sales can release cash and add occasional lumpy profit, and a Bank of England rate cut to 3.75% may help buyers a little, but it is too small to change the growth path.

The case against

The first problem is price. At 21 times earnings, Kier costs far more than Bouygues, Kajima, STRABAG, Obayashi and Taisei, which trade at 11 to 12 times and earn higher operating margins. Only HOCHTIEF and ACS are dearer, and both have much stronger growth records to justify it. Kier looks less stretched on enterprise value, the value of the shares adjusted for cash and debt, against operating profit: 8.8 times, helped by its net cash. But on plain earnings, investors are paying a premium for a company not growing faster than its cheaper peers.

The second is the thinness of the margins: 3.3% of sales kept as operating profit and 1.4% as net profit. At those levels a single contract that runs over budget can wipe out a large share of a year's earnings, as construction's history shows. The stable gross margin and net cash cushion that risk without removing it.

The third is that the recent excitement is less than it looks. The shares' climb has largely carried them back to where they stood relative to the market a year ago, and Kier's growth record against other companies is still weaker than twelve months ago. As the price has run, the shares remain cheaper than most of the market, but by a narrower margin than six months ago.

What the price assumes

The shares have risen 42% over the past year, and 52% over the past six months alone. The question is how much growth the price now demands.

Less than the headline multiple suggests. If the share price stayed flat and, in five years, Kier traded at 18.5 times earnings, the typical level for profitable listed companies we cover, earnings would need to grow only about 3% a year, to 0.17 a share. If the recent trend in operating profit simply continued, earnings would instead reach about 0.23 a share, 139% of what the price requires, implying growth of about 10% a year. That is Kier's own past carried forward, not a forecast, but it sits comfortably above the bar, and analysts' expected 8% rise next year points the same way.

So the price does not need a miracle. The tension is that the valuation is high against peers today, and the comfort in the arithmetic depends on the margin staying where it is.

The other side of the medal

The risk that matters most is that a 3% operating margin leaves little cushion if fuel and material costs outrun what contracts let Kier recover. Brent crude has risen 88% over the past year to $123 a barrel, and a contractor that lays roads and runs fleets of vehicles feels that directly in diesel and road-surfacing bills.

Kier is unusually exposed: among nine comparable companies, only one runs on a narrower margin. A cost rise that a contract cannot pass on comes straight out of a 9% gross margin, and the operating margin has far less room still. Much depends on how many of Kier's long frameworks carry clauses that let rising costs be charged back to government and utility customers.

The first sign of trouble would be the gross margin slipping from the narrow band it has held for years, or management talking about contracts where cost recovery lags behind the bills.

What to watch

The central question is whether the operating margin holds at 3% or better while the order book keeps growing as old contracts finish. The early evidence will come in trading updates and contract announcements rather than full results: framework wins on roads, rail, and justice and defence buildings, and new or extended water contracts, would show the pipeline refilling before the profit shows up.

Input costs are the other early signal. With oil sharply higher, any comment on how much extra cost is being recovered from customers will matter more than the headline sales figure. The reading fails if the gross margin slips even a point or two from around 8%, or if operating profit stalls short of the latest 145m. With a net margin of 1.4%, Kier has almost no room to absorb a bad contract.
