Serco delivers resilient first-half performance with margin progression and reaffirms full-year guidance

Serco first-half 2026 trading update: steady growth, better margins and no downgrade

Serco has put out a solid first-half trading update, and the headline is pretty simple: trading is on track, margins are improving, cash generation still looks healthy, and full-year guidance has been left unchanged.

That matters because in this market, investors often care just as much about what has not happened as what has. There is no profit warning here, no cut to revenue guidance, and no sign that the delays in North America have knocked the wider group off course.

Why Serco’s margin progression is the standout feature

The most encouraging bit of this update is not the revenue growth. It is the margin improvement. Serco expects first-half underlying operating profit of around £155 million, up approximately 6% year-on-year, with margin above 6%.

That tells you profit is growing faster than sales, which is usually what investors want to see from an outsourcing and government services business. Management says this is being driven by productivity improvements, efficiency programmes, disciplined cost control and a better revenue mix.

For the full year, Serco still expects around £300 million of underlying operating profit, versus £272 million in 2025. It also expects a margin of around 6.0%, which is roughly 40 basis points higher than last year. A basis point is one hundredth of a percentage point, so 40 basis points means 0.4 percentage points.

In plain English, Serco is squeezing more profit out of each pound of revenue. That is a good sign, especially when some parts of the business are facing external pressure.

Serco revenue growth: UK and Europe strong, North America delayed, Asia Pacific rebuilding

The regional picture is mixed, but mostly in a sensible rather than alarming way.

• UK performance has been strong, helped by Defence contract mobilisations, better Justice performance and higher-than-expected immigration-related revenue.
• North America is still dealing with procurement delays that first showed up towards the end of 2025, although the MT&S contribution helped offset that.
• Middle East revenue was partly affected by regional conflict, with some reductions in activity and contract rescoping.
• Asia Pacific saw revenue decline as expected because of the end of the immigration contract, but order intake was over £500 million.

That mix matters. Serco is showing that weakness in one region is being balanced by strength elsewhere, which is one of the advantages of having a broad government services footprint.

The company is also sticking with its full-year organic growth guidance of around 3%, even though the first half was only around 1%. That implies a stronger second half, supported by UK and Australia contract mobilisations, the annualisation of the Asia Pacific contract exit, and an expected improvement in North American procurement.

That is credible, but it is also one of the key things investors will need to watch. When a company leans on a better second half, execution matters.

Serco pipeline and order book support the full-year guidance

The pipeline has increased to £12.5 billion, and Serco says it has secured over £2 billion of contract awards and extensions. That is important because this is a business where future revenue visibility matters almost as much as current trading.

North America is the interesting one here. Procurement delays are still a drag, but management says the pipeline of potential new work has expanded further. So while contracts are taking longer to move, the underlying demand picture appears intact.

That supports management’s confidence, although investors should remember a pipeline is not the same thing as signed revenue. It is encouraging, not guaranteed.

Balance sheet, cash flow and Serco’s revolving credit facility all look comfortable

Financially, this was another reassuring part of the update. Adjusted net debt is expected to be around £250 million at the end of June, with leverage below 1.0x. Leverage here means debt relative to earnings, and below 1.0x is a pretty modest level.

Serco also refinanced its revolving credit facility – effectively a flexible borrowing line – increasing it from £350 million to £400 million and extending maturity to June 2031. That gives the group more liquidity and more breathing room.

Full-year free cash flow guidance remains around £160 million, with adjusted net debt expected to reduce to around £165 million by year end. Cash generation is expected to be weighted to the second half, which the company says is normal.

On top of that, the current £75 million share buyback is due to finish by the end of July. After that, the board will review the capital position. That may catch investor attention, because it leaves the door open to further capital returns, although nothing additional has been disclosed.

What to make of the Serco North America CEO transition

There was one management change tucked into the announcement. Michael LaRouche, CEO of Serco’s North America division, is leaving to take up a CEO role at another international business with a US listing.

He will stay on for an orderly transition, and the successor process is underway. This is not ideal timing given the procurement delays in the US, but neither does it read like a sudden disruption. For now, it looks manageable rather than a red flag.

My view: a good Serco update, but the second half still needs to do some work

Overall, this is a positive update. Serco is growing, margins are improving, the balance sheet looks sound, the pipeline is moving in the right direction, and full-year guidance has been reiterated.

The biggest positive is quality of earnings. Better margins, strong contract retention, healthy liquidity and continued buybacks make this look more robust than a simple revenue story.

The main caution is that a chunk of the full-year confidence rests on a stronger second half, especially in North America and through contract mobilisations elsewhere. That is not unusual, but it does mean investors should keep an eye on delivery over the next six months.

Still, based on this RNS alone, Serco looks like a business doing what shareholders would hope for – keeping the ship steady, improving profitability, and giving no sign that this year is slipping off plan.
