Hyder Consulting, a design and engineering consultancy, disappointed with its full-year results on Wednesday, which came in below both its original expectations and the prior year.
Income was affected by delays in new contract awards in Australia due to the election and a poor performance in Germany, which it has since restructured.
On a statutory basis, pre-tax profit came in at £5.4m, compared to £16.6m a year earlier, with earnings per share falling to 8.39p, down significantly from the 30.72p delivered the previous year.
Revenue totalled £296.8m, down slightly from £298.1m.
Chairman Sir Alan Thomas said: "Although group results for the year are below our original expectations, trading in the UK and the Middle East continues to be strong. This highlights the value of our technical skill base and a regionally balanced business.
"The flexibility enabled by our design excellence centres allows us to concentrate resources on growing markets. We have a solid pipeline, record order book and are confident we will continue to capture a sizeable share of our target markets."
The group said it has good bidding opportunities in Australia and performed well in both the Middle East and UK.
At £440m, its order book is its highest to date, with a broadly spread pipeline of opportunities across the group, with particularly strong growth in the Middle East and the UK. More than 60% of the current year's forecast revenue is already secured.
Shares had fallen 4.57% to 454.25p in the first two hours of trade.
Online betting exchange Betfair thrashed analysts' full year forecasts as management tackled the cost base and the introduction of a more traditional bookmaker's sportsbook and increased marketing gave a much-needed kick to customer acquisition.
While underlying revenue rose a modest 2% to £393.6m in the year to end-March, the new focus on efficiency saw earnings before interest, tax, depreciation and amortisation (EBITDA) jump 24% to £91.1m and basic earnings per share leap 57% to 49p, ahead of analyst consensus of less than 46p.
The dividend was 54% higher at 20p, lifted by the proposal of a 14p final payout. Year end net cash stood at £210m, which some analysts had expected might results in a special dividend.
"Our strategy is working," said Chief Executive Breon Corcoran, referring to a turnaround that began in December 2012 to focus on sustainable markets, the sportsbook and reduce inefficiency.
Revenues from sustainable markets - which it defined as the UK, Ireland, Denmark, Malta, Gibraltar and US - now contribute 78% of group revenues, up from 72% the year before. Other markets are expected to decline by 15-25% per annum, worse than forecast.
Corcoran said the efficiency push allowed operating margin expansion at the same time as increasing marketing and technology investment to around £200m.
He said the company was now entering "an exciting phase of product development" to leverage both its exchange and sportsbook "to stand out in a crowded marketplace".
New sports betting products such as Cash Out and Price Rush, which integrates the sportsbook with better prices on the exchange, were powerful means of differentiating the company from competition and changing the ways customers bet.
"The introduction of the sportsbook, increased television advertising spend and the strengthening of our online marketing capability have broadened our customer reach and led to a 54% increase in the number of customers acquired in the UK and Ireland," he added.
Revenues were weak from gaming, falling 13% to £66.2m primarily due to the continued decline in poker and management's decision to focus on revenues in 'sustainable markets'.
Strong trading has continued into the new financial year, providing good momentum as the World Cup kicks off on Thursday.
