Serco stock reports 4 percent H1 revenue growth

Serco stock closed at GBp 252.80 on the LSE on September 24, 2026, down 0.47 percent from the previous close of GBp 254.00. The government services group reported first-half 2026 revenue of GBP 2.5 billion, up 4 percent year over year.

Revenue growth reaches 4 percent

According to Simplify Jobs, Serco generated GBP 2.5 billion in revenue in the six months ended June 30, 2026. That figure was 4 percent higher than in the comparable period, giving investors a clear measure of the group's operating scale.

The improvement was broad enough to support profit expansion. Underlying operating profit rose 9 percent to GBP 157 million in H1 2026, while the operating margin increased by 20 basis points to 6.2 percent, according to Simplify Jobs.

Guidance remains the key test

Serco's investor page describes the first-half performance as strong and states confidence in full-year guidance, a position presented by Serco. The combination of 4 percent revenue growth and a 6.2 percent margin shifts attention toward delivery in the second half.

Cash generation is also material for the investment case because government-services contracts typically require disciplined cost control. Serco's first-half operating profit of GBP 157 million therefore matters more than revenue growth alone, since the 9 percent profit increase exceeded the 4 percent sales increase.

Stock stays below yearly high

Serco's closing price of GBp 252.80 on September 24, 2026, sat between the 52-week low of GBp 218.40 and high of GBp 325.80. The 0.47 percent daily decline leaves the stock below its yearly high while the latest operating figures show higher profit conversion.
