Security firm G4S has said the Olympic fiasco would cost it £50m and it was fighting to rebuild its reputation.
The company was at the centre of a political and media storm over its failure to provide enough guards for the London Olympics,
CEO Nick Buckles, pledged that there would be no repeat problems at the Paralympic Games, starting on Wednesday.
He also said there were no signs the company was losing contracts or not winning new ones and that, with £3.8 billion of work per year in its pipeline, it should bounce back.
However, not all analysts were convinced, pointing to the company's decision to freeze its interim dividend, and G4S shares were down over 2% in morning trade.
"The unchanged interim dividend suggests some caution from management, especially with a number of key government contract decisions coming up during H2 2012," said Panmure's Mike Allen.
Over half of G4S's British revenue comes from government contracts, with more than 20% of its pipeline also stemming from that market, including deals to run prisons and some police services due later this year.
Seymour Pierce analyst Caroline de La Soujeole said Buckles' appearance before parliament's Home Affairs Committee on Sept. 11 could be crucial, ahead of the first wave of prison outsourcing contracts in the autumn.
G4S, with 657,000 staff in over 125 countries, said the findings of a board review into the Olympic contract failure would be available in late September. British lawmakers are also holding an inquiry into the debacle.
The firm said £50m was its estimate for the cost of paying military and police personnel drafted in to cover the shortfall in guards, as well as potential penalties and liabilities.
G4S managed to provide 7,800 staff for the Olympic Games at peak times, compared with a promised 10,400.
Buckles kept his job last year despite caving in to investor pressure to scrap a £5.2 billion acquisition of Danish cleaning firm ISS at a cost of around £50m, and has so far been largely backed by shareholders to survive again.
"I hope I keep my job, I've been with the company now 28 years, 10 years as CEO and I think we have delivered good returns for investors, but clearly that decision is going to be down to the board," he said.
G4S posted a profit before interest, tax and amortisation for the six months to June 30 of £236m, flat on last year, with revenue up 5.8% to £3.9 billion.
Emerging markets, where G4S is aiming to grow revenue from 30% to 50% by 2019, performed strongly in the period, winning financial services and government work in Latin America.
G4S has trimmed its portfolio with business disposals in Sweden and the United States in the first half of the year and said it had also shed 1,100 jobs in the period as part of a restructuring drive to cut annual costs by £30m.
The group, which this month donated £2.5m to British military sports and welfare organisations to thank troops who guarded Olympic venues in its absence, kept its interim dividend at £3.42 per share.
