Directors report Directors report The Directors of Calibre Group Limited (Calibre, the Company or the consolidated entity) present their report and consolidated financial report for the half-year ended (half-year) as follows: The names of Directors in office at any time during or since the end of the half-year are: Geoff Tomlinson Brian MacDonald Peter Massey Anne McIntyre Ray Munro Graham Smith Dod Wales Chairman Non-Executive Director Managing Director Non-Executive Director Non-Executive Director Non-Executive Director Non-Executive Director The above Directors were in office for this entire period unless otherwise stated. Principal activities Calibre is a leading diversified provider of engineering, consulting, project delivery, construction, maintenance and asset management services within Australasia offering clients an integrated range of services, from early-stage asset evaluation and project feasibility studies, through design and delivery, to ongoing support and optimisation of the resources, infrastructure, utilities, urban development, defence and transport sectors. Operating & Financial Review Financial overview Calibre s revenue for the six months ended was $306.3m, up 42% on revenue of $215.8m for the previous corresponding period. Operating cash flow for the six month period was $12.2m, an increase of $8.7m from the prior corresponding period, reflecting a strong focus on working capital management. Net capital expenditure during the period was $2.8m. For the half year ended, Calibre reported a 9% increase in an underlying EBITDA to $5.7m. Similar to, Calibre s first half results are traditionally impacted by seasonal events relating to the start of the new financial year, calendar year-end holidays and timely ramp up of new projects. Reflecting the $92.9m increase in revenue in the Construction & Maintenance business, reported EBITDA for this business was up $5.4m to $6.9m. At the same time, an increasingly competitive market and continuing challenges in the resources sector contributed to the $4.6m decline in EBITDA for the Professional Services business to $0.3m. The Group s underlying EBITDA excluded a gain in fair valuing contingent consideration of $0.2m ( 2016: $7.0m), restructuring expenses of $0.2m ( 2016: $1.7m) and business acquisition costs of $0.6m (31 December 2016: $1.0m). For the six months ended Calibre generated a net loss before tax of $6.1m, reflecting $7.7m in depreciation and amortisation charges and $3.6m of net financing costs. A decline of $0.9m from the prior corresponding period, depreciation and amortisation for the period reflects lower capital expenditure programs in place across the business. The $0.9m increase in financing costs reflects the higher costs associated with new preference shares and convertible note arrangements. Liquidity Calibre s net borrowings as at was $57.2m (30 June : $58.5m), after offsetting cash and cash equivalents of $25.1m (30 June : $16.7m). Current borrowings declined from $72.5m at 30 June to $32.6m at, reflecting the outcome of the new four year senior bank facility arrangements completed during the period. During the period ended, Calibre made $4.4m of scheduled debt repayments. At Calibre s total borrowings comprised bank borrowings of $76.0m (30 June : $70.0m), finance and hire purchase liabilities of $6.2m (30 June : $5.2m), convertible notes and preference share liabilities of $27.5m (30 June : $1.7m) and deferred acquisition consideration of $0.3m (30 June : $30.5m). New bank borrowings of $5.0m and convertible notes of $25.0m were secured during the period to fund the final earn out payments of $30.0m in relation to the acquisition of the Diona business in 2015. CALIBRE GROUP LIMITED HALF YEAR REPORT 2

Directors report (continued) Taxation Income tax expense for the period is $nil. Net deferred tax assets of $15.7m arise from deductible timing differences and tax losses. Deferred tax assets of $19.4m relating to carry forward income tax losses and research & development credits that are available for offset against future taxable profits are not recognised. Business Line Performance Calibre provides services through two key segments being Professional Services and Construction & Maintenance. A summary of each business line s performance during the period is set out below. Construction & Maintenance (CM) CM operates as the Diona civil engineering business servicing the east coast infrastructure market and the G&S Engineering business providing maintenance and construct services to the resources sector. CM revenue for the half year was $223.6m, an increase of 71% from the prior corresponding period. Personnel costs across the business increased during the period, as it positions a number of the teams for the next phases of growth and to ensure the appropriate client and risk management profiles are in place. Diona reported revenue of $114.9m, 56% ahead of the prior year, with the main projects contributing to the revenue and earnings increases include the delivery of design and construct Powells Creek Bank Renewals, Woolloomooloo Sewer Separation and Canterbury Town Centre Works. Work on hand during the period increased with major new projects awarded during the period including the Transgrid TRNG 330kv cable project, Ausgrid Canterbury to Summerhill 33kv cable project and West Connex 630 Water Main. Diona has a strong order book and pipeline, and is continuing to project strong growth into future financial years. Revenue for G&S Engineering business increased by 90% to $108.7m. This increased revenue was due to improving market conditions in the Australian coal market driving increased work activities in both the major projects and maintenance sectors. Revenue from maintenance activities also was up $22.0m to $75.0m due to increased shutdown and maintenance spend in the Bowen Basin. Revenue in major projects was up $29.0m to $33.0m from the previous corresponding period, reflecting the progress made on the joint venture EPC contract with DRA for the Mt Pleasant CHPP. The project has just passed through the 50% completion and is ramping up to peak site workforce as construction activities accelerate. The project has not yet delivered to financial plan or outcomes, with a number of commercial matters currently being assessed, contributing to the Group s decline in gross margins. Order book remained relatively steady during the period, with key awards granted during the period at Caval Ridge and securing a role on the BHP Iron Ore Construction Panel. G&S Engineering was also successful in negotiating renewals or extensions of key maintenance agreements within Queensland. Professional Services (PS) Revenue for the PS business was relatively steady at $84.2m, down $1.3m, from the prior corresponding period. The PS business settled down a number of aspects of its organisational restructure during the period, including appointing a number of new key management roles. The outlook in many of PS markets are improving significantly, particularly in WA, as the iron ore and other sectors evaluate both new brownfield and greenfield opportunities. The buoyant east coast urban development and infrastructure markets are also contributing to stronger market outlook. A new division called Building and Renewable was set up to provide complementary services to existing client base and expansion into the different market. Management are implementing many of their operational plans to address the increasingly competitive nature of many of PS markets and operational inefficiencies that have contributed to a decline in gross margins in the period. Since 31 December, the current run-rate on new work awards, earnings performance improvements and a full management team are expected to result in a significantly improved second half. Significant events after the balance date Subsequent to the end of the reporting period, the Directors have confirmed, as part of the Company s strategic review and in light of being informed of the desire of First Reserve to exit its shareholding in Calibre, that the Company will start to progress with two independent processes to sell the G&S Engineering business to one party, and the combined Calibre Professional Services and Diona businesses to another. The Professional Services business is a separate reportable segment, whilst the G&S Engineering and Diona businesses form the consolidated entity s Construction & Maintenance reportable segment. As a result, Calibre is subsequent to the reporting period in advanced discussions with various bidders in relation to the G&S Engineering business, and negotiations have entered a due diligence phase with a view to a final offer being made shortly to the Company. CALIBRE GROUP LIMITED HALF YEAR REPORT 3

Directors report (continued) Significant events after the balance date (continued) Calibre has also commenced a second process by a consortium who has expressed an interest in acquiring the Calibre Professional Services and Diona businesses. The consortium consists of a private equity bidder and the former owners of the Diona business, who also hold convertible loan notes that were issued by the Company in late. To facilitate this second process, the Company has granted an eight-week exclusivity period commencing on 15 March 2018 to allow due diligence and sale and purchase terms to be agreed. The current convertible noteholders have agreed to a number of modifications to the terms of the notes to facilitate this second process to occur seamlessly. Significant changes in the state of affairs There have been no significant changes in the state of affairs during the half year. Indemnification and insurance of officers and auditors During or since the financial period, the Company has paid premiums in respect of a contract insuring all directors and the officers which indemnifies them against claims made against them subject to the conditions contained within the insurance policy. Further disclosure required under section 300(9) of the Corporations Act 2001 is prohibited under the policy terms. No indemnities have been given or insurance paid for the auditors of the Company. Auditor s independence declaration The auditor s independence declaration is included on page 6 of the half-year financial report. Dividends No dividend has been declared in respect of the half year ended ( 2016: nil). Rounding The amounts contained in this report and in the financial report have been rounded to the nearest $1,000 (where rounding is applicable) and where noted ($ 000) under the option available to the Company under ASIC Instrument 2016/191. The Company is an entity to which the Instrument applies. This Directors Report is signed in accordance with a resolution of Directors made pursuant to section 306(3) of the Corporations Act 2001.

Notes to the financial statements Notes to the financial stateme nts for the half-year ended 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES a) Statement of compliance The half-year financial report of Calibre Group Limited and the entities it controlled at the end of the half-year (the Company or the consolidated entity) is a general purpose financial report prepared in accordance with the Corporations Act 2001 and AASB 134 Interim Financial Reporting. Compliance with AASB 134 ensures compliance with International Financial Reporting Standard IAS 34 Interim Financial Reporting. The half-year report does not include all of the notes of the type normally included in an annual financial report and shall be read in conjunction with the most recent annual financial report. b) Basis of preparation The condensed consolidated financial statements have been prepared on the basis of historical cost, except for the revaluation of certain non-current assets and financial instruments. Cost is based on the fair values of the consideration given in exchange for assets. All amounts are presented in Australian dollars, unless otherwise noted. The company is a company of the kind referred to in ASIC Corporations (Rounding in Financial/Directors Reports) Instrument2016/191, the Directors have chosen to round amounts in this Directors Report and the accompanying half year financial report to the nearest hundred thousand dollars, unless otherwise indicated. The accounting policies and methods of computation adopted in the preparation of the half-year financial report are consistent with those adopted and disclosed in the consolidated entity s annual financial report for the financial year ended 30 June, except for the impact of the Standards and Interpretations in note 12. These accounting policies are consistent with Australian Accounting Standards and with International Financial Reporting Standards. Where applicable, comparative information has been reclassified or restated where there has been a retrospective application of an accounting policy, a retrospective restatement, or reclassification of items in the financial statements in order to comply with current period disclosure requirements. c) Going concern The financial report for half-year ended has been prepared on the going concern basis, which assumes the consolidated entity will be able to realise its assets and discharge its liabilities in the normal course of business. The consolidated entity had net operating cash inflows for the half-year ended of $12.2m, and the Directors are forecasting continuing net operating cash inflows. The consolidated entity generated a net loss after tax of $6.1m after depreciation and amortisation charges of $7.7m and $3.6m of net financing costs which translates to a positive EBITDA of $5.7m. The Directors were able to successfully refinance $131.5m in borrowings of the consolidated entity during the period, through a combination of four year senior bank facility, three year convertible preference shares and three and one year convertible notes. The convertible notes and convertible preference shares have contributed to higher financing costs during the period. At, the consolidated entity s current liabilities exceed its current assets by $10.7m (30 June : net current liability position of $74.9m). The net current liability position is a result of the consolidated entity s one year convertible notes reaching maturity on 31 October 2018. Accordingly, the amount outstanding in respect of the convertible notes of $15.5m has been classified as a current liability as at. Calibre is experiencing an increase in client and project enquiries and growth in its forward order book, particularly in its key infrastructure and resources end markets. The consolidated entity s growth in revenues and operations is placing working capital demands on the business, with management having activated and continuing to explore a range of options to assist in managing this position. In an effort to best position Calibre and its businesses to take advantage of its growth and to enable the redemption of the convertible notes prior to maturity, the Directors continue to review the consolidated entity s business portfolio and capital management, particularly in light of being informed of the desire of First Reserve to exit its shareholding in Calibre. Subsequent to the reporting period, the Directors have confirmed that the Company will progress with two independent processes to sell G&S Engineering segment to one party, and the combined Calibre Professional Services and Diona segments to another. As a result, Calibre is currently in advanced discussions with various bidders in relation to the G&S Engineering business, and negotiations have entered a due diligence phase with a view to a final offer being made shortly. CALIBRE GROUP LIMITED HALF YEAR REPORT 11

Notes to the financial statements (continued) c) Going concern (continued) Calibre has also commenced a second process by a consortium who has expressed an interest in acquiring the Calibre Professional Services and Diona businesses. To facilitate this second process, the Company has granted an eight-week exclusivity period starting today to allow due diligence and sale and purchase terms to be agreed. The current convertible noteholders have agreed to a number of modifications to the terms of the notes to facilitate this second process to occur seamlessly. The consortium have proposed a fixed floor price for the Professional Services and Diona businesses, with the current intention of the Board to accept a final offer from the consortium if it is made at or above the fixed floor price, and to use the proceeds from the sale to repay bank debt and redeem the convertible notes. If the Professional Services and Diona businesses are sold for the fixed floor price, the Board expects that there will be sufficient cash to repay all debt while still retaining a cash surplus. However, given the uncertainty as to the outcomes of options being advanced by the Company and the level and timing of funds available to redeem the one year convertible notes maturing on 31 October 2018, the combined circumstances give rise to a material uncertainty as to the ability of the consolidated entity to continue as a going concern and therefore the consolidated entity s ability to realise its assets and discharge its liabilities in the ordinary course of business.

Notes to the financial statements (continued) 2. SEGMENT INFORMATION The consolidated entity s operating segments are based on the information that is available to the chief operating decision maker and the Board of Directors. The segment results and segment assets include all items directly attributable to each of the segments and any transaction, asset or liability that can be allocated on a reasonable basis. Unallocated items comprise predominantly of expenses that are not specific to the performance of an individual operating segment. The following are the reportable segments: Construction & Maintenance This segment provides construction, operations maintenance, and asset management services to the resources, energy, infrastructure and utility sectors. Professional Services This segment is responsible for the delivery of integrated services across the asset lifecycle to the resources, urban development and infrastructure markets. The accounting policies used by the consolidated entity in reporting internally are the same as those contained in the notes to the financial statements except for the unallocated items detailed below. The following items and associated assets and liabilities are not allocated to the operating segment as they are not considered part of the core operations: Restructuring expenses; Interest receivable and payable; and Depreciation and amortisation of intangible assets. Following is an analysis of the Group s revenue and results from continuing operations by reportable segment.

Pursuant to the EGIP, during the period, the Company provided 4.52m shares to employees at $nil consideration. The shares granted have no vesting conditions. The fair value of shares provided was determined by an independent valuation. This value was derived using a capitalised earnings method adjusted for normalisation adjustments. During the half-year ended, the Company granted 3.4m performance rights to employees, subject to satisfying specific service conditions. 4.

Notes to the financial statements (continued) 10. DIVIDENDS No dividend has been declared in respect of the half year ended ( 2016: nil). 11. EVENTS AFTER BALANCE SHEET DATE Subsequent to the end of the reporting period, the Directors have confirmed, as part of the Company s strategic review and in light of being informed of the desire of First Reserve to exit its shareholding in Calibre, that the Company will start to progress with two independent processes to sell the G&S Engineering business to one party, and the combined Calibre Professional Services and Diona businesses to another. The Professional Services business is a separate reportable segment, whilst the G&S Engineering and Diona businesses form the consolidated entity s Construction & Maintenance reportable segment. As a result, Calibre is subsequent to the reporting period in advanced discussions with various bidders in relation to the G&S Engineering business, and negotiations have entered a due diligence phase with a view to a final offer being made shortly to the Company. Calibre has also commenced a second process by a consortium who has expressed an interest in acquiring the Calibre Professional Services and Diona businesses. The consortium consists of a private equity bidder and the former owners of the Diona business, who also hold convertible loan notes that were issued by the Company in late. To facilitate this second process, the Company has granted an eight-week exclusivity period commencing on 15 March 2018 to allow due diligence and sale and purchase terms to be agreed. The current convertible noteholders have agreed to a number of modifications to the terms of the notes to facilitate this second process to occur seamlessly. 12.

Independe nt Auditor s re port Independ ent Auditor s Report to the memb ers of Calibre Group Limited Deloitte Touche Tohmatsu ABN 74 490 121 060 Grosvenor Place 225 George Street Sydney NSW 2000 PO Box N250 Grosvenor Place Sydney NSW 1219 Australia DX: 10307SSE Tel: +61 (0) 2 9322 7000 Fax: +61 (0) 2 9322 7001 www.deloitte.com.au Independent Auditor s Review Report to the members of Calibre Group Limited We have reviewed the accompanying half-year financial report of Calibre Group Limited, which comprises the condensed statement of financial position as at, and the condensed statement of profit or loss and other comprehensive income, the condensed statement of cash flows and the condensed statement of changes in equity for the half-year ended on that date, notes comprising a summary of significant accounting policies and other explanatory information, and the directors declaration of the consolidated entity comprising the company and the entities it controlled at the end of the half-year or from time to time during the half-year as set out on pages 5 to 19. Directors Responsibility for the Half-Year Financial Report The directors of the company are responsible for the preparation of the half-year financial report that gives a true and fair view in accordance with Australian Accounting Standards and the Corporations Act 2001 and for such internal control as the directors determine is necessary to enable the preparation of the half-year financial report that gives a true and fair view and is free from material misstatement, whether due to fraud or error. Auditor s Responsibility Our responsibility is to express a conclusion on the half-year financial report based on our review. We conducted our review in accordance with Auditing Standard on Review Engagements ASRE 2410 Review of a Financial Report Performed by the Independent Auditor of the Entity, in order to state whether, on the basis of the procedures described, we have become aware of any matter that makes us believe that the half-year financial report is not in accordance with the Corporations Act 2001 including: giving a true and fair view of the consolidated entity s financial position as at and its performance for the half-year ended on that date; and complying with Accounting Standard AASB 134 Interim Financial Reporting and the Corporations Regulations 2001. As the auditor of Calibre Group Limited, ASRE 2410 requires that we comply with the ethical requirements relevant to the audit of the annual financial report. A review of a half-year financial report consists of making enquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with Australian Auditing Standards and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion. Auditor s Independence Declaration In conducting our review, we have complied with the independence requirements of the Corporations Act 2001. We confirm that the independence declaration required by the Corporations Act 2001, which has been given to the directors of Calibre Group Limited, would be in the same terms if given to the directors as at the time of this auditor s review report. Liability limited by a scheme approved under Professional Standards Legislation. Member of Deloitte Touche Tohmatsu Limited CALIBRE GROUP LIMITED HALF YEAR REPORT 20

Conclusion Based on our review, which is not an audit, we have not become aware of any matter that makes us believe that the half-year financial report of Calibre Group Limited is not in accordance with the Corporations Act 2001, including: (a) (b) giving a true and fair view of the consolidated entity s financial position as at and of its performance for the half-year ended on that date; and complying with Accounting Standard AASB 134 Interim Financial Reporting and the Corporations Regulations 2001. Material Uncertainty Related to Going Concern We draw attention to Note 1 in the half-year financial report, which indicates that the consolidated entity s current liabilities exceeded its current assets by $10,700,000 as at. As stated in Note 1, this condition along with other matters as set forth in Note 1, indicate that a material uncertainty exists that may cast significant doubt on the consolidated entity s ability to continue as a going concern. Our conclusion is not modified in respect of this matter. DELOITTE TOUCHE TOHMATSU Suzana Vlahovic Partner Chartered Accountants Sydney, 16 March 2018 CALIBRE GROUP LIMITED HALF YEAR REPORT 21
