Leighton Holdings Limited Shareholder Update as at 14 August 2013 6 The result for the six months to 30 June 2013 (HY13) showed the positive progress of the Group s stabilise, rebase and grow strategy, combined with the benefits of diversification by brand, market sector and geography, in challenging macroeconomic conditions. The highlights of the result were: Revenue of $11.5 billion, up 4% on HY12 Net Profit after Tax (NPAT) of $366 million, up 218% on HY12 Underlying NPAT 1 of $255 million, up 122% on HY12 Underlying NPAT margin of 2.2% of revenue, up from 1% in HY12 Interim dividend of 45 cents per share, 50% franked Gearing 2 of 36%, down from 47.7% at 31 March 2013 Cash inflows from operating activities of $148 million Work in hand of $40.1 billion, down 5% from 31 March 2013. A further $3.9 billion of work won since 30 June 2013 On track to deliver 2013 full year underlying NPAT of $520 to $600 million and a gearing level within the target band of 25 to 35% by year-end, subject to market conditions and any unforeseen circumstances. Better financial performance, margin improvement Leighton Holdings' Chief Executive Officer, Mr Hamish Tyrwhitt, said: The higher revenue, margin and net profit achieved during the first half shows the clear turnaround of our business. The result demonstrates the strength of our business model and the relevance of our strategy amid challenging market conditions. Leighton s diversity not just by market sector, geography and brand, but also by contract type and size, activity, and customer allowed the Group to withstand headwinds in contract mining during the period and enabled us to deliver an improved operating performance. There are still challenges within our business. However, for each challenge we have a clear pathway to resolution and we are making good progress. During the second half of 2013, we will accelerate the rebase element of our strategy in order to expand the underlying NPAT margin and position the Group to meet the infrastructure demand in our addressable markets. Delivery on the balance sheet As at 30 June 2013, cash and equivalents were $1.9 billion, broadly stable compared to 31 December 2012. The Group received $614 million in pre-tax cash proceeds from the partial sale of its non-core telecommunications assets in June 2013. Gearing was 36% as at 30 June 2013. Gearing is expected to improve to between 25 and 35% during the second half, driven by stronger operating cash inflows. Work continued during the period on the management of working capital and capital expenditure. However, further progress is essential to drive a sustainable improvement in operating cash flows. The Group expects resolution on a number of underclaims 3 and contract debtors during the remainder of the year. Mr Tyrwhitt said: Rebuilding the Group s balance sheet and improving working capital are crucial to transforming the business. Detailed plans are in place to drive the recovery of receivables. Securing high quality, diversified work As at 30 June 2013, the Group had a diversified portfolio of $40.1 billion of work in hand, a further $7.8 billion in contracts beyond five years and preferred bidder positions of $3.1 billion. During the six weeks since 30 June 2013, the Group won a further $3.9 billion worth of contracts. The Group s focus is on achieving better operating margins, rather than expanding revenue at low margins. Mr Tyrwhitt said: Through the economic cycle some sectors will grow and some will contract. This is where our diversity comes in. During the period, we saw a different mix within the portfolio as we won work in Australian LNG construction and in Asia Pacific social and economic infrastructure. The work in hand project margin was approximately 10%, the result of a selective approach to tendering for new work amid challenging market conditions. We do not need to expand our book to deliver growth to our shareholders in the immediate future. Rather, we will optimise returns from the strong order book that we have while focusing on operating efficiencies. Half Year Results Leighton Holdings Limited recently announced an improved result for the six months to 30 June 2013 (HY13) demonstrating the resilience of its operations.

Completion of sale of telecommunications assets During the period, the Group sold 70.1 % of its non-core telecommunications assets to Ontario Teachers Pension Plan, retaining 29.9 % in order to access the upside value created by the new joint venture ownership structure. Proceeds of the sale were used to strengthen the balance sheet and reduce gearing. Habtoor Leighton Group (HLG) The Group s business in the Middle East, HLG, showed some signs of improvement. HLG achieved a break-even result during the first half and recovered funds from UAE legacy projects. The region s macroeconomic environment has stabilised and a robust pipeline of projects is being pursued. The decision of a Qatar-based client to call bonds on certain legacy projects delayed HLG from making repayments on Leighton s outstanding shareholder loans during the period. HLG believes its legal position on the matter is strong and it is working to a resolution. HLG s focus continues to be the collection of receivables and IPO-ready 2016 remains the target. The business is diversifying its sector and geographic base, and it continues to secure new work. Business transformation Mr Tyrwhitt said the Group was progressing on a number of initiatives that would accelerate the stabilise, rebase and grow strategy. To deliver on margin improvement we are focusing on five fundamental areas. First, reducing working capital continues to be a focus. Second, we are continuing to harness the benefits of the scale of our business through strategic procurement. Third, we are continuing our move to standardise business support processes within a Group-wide, shared services environment. This will enable us to deliver efficiencies whilst maintaining the diversity and integrity of our brands. Fourth, we are well progressed in the establishment of our single fleet management vehicle and we are taking a Group-wide approach to the management of all our assets. Finally, we are ensuring that we have the right management structures for our addressable markets. Through these initiatives we expect approximately $200 million in savings to be realised this year. Outlook The Group remains on track to deliver a 2013 full year underlying NPAT within $520 to $600 million and a gearing level within the target band of 25 to 35% by year-end, subject to market conditions and any unforeseen circumstances. Mr Tyrwhitt said: Once the rebase phase of our strategy is complete, Leighton will be well positioned for our next phase of growth. The Asia region is projected to experience significant economic expansion over the coming years. This expansion will require considerable infrastructure investment. With 38 years experience in Asia we are well positioned, geographically and operationally, in what will be one of the key growth markets of the world during the next 50 years. 1 Underlying NPAT is NPAT adjusted for gains or losses on sale and impairments. 2 Gearing is expressed as the ratio of net debt and operating leases to net debt, operating leases and shareholder equity. FY12 has been adjusted to include the impact of adoption of AASB 11 Joint Arrangements. 3 Underclaims represent work or variations that have been performed for clients but have not yet been billed. Once billed, they become contract debtors. Both are recorded within trade receivables. 7
