Independent Auditors Report

To the Partners of

Amboy Aggregates Joint Venture and
Subsidiaries:

We have audited the accompanying consolidated financial statements of Amboy Aggregates Joint Venture and Subsidiaries (the
Companies) which comprise the consolidated balance sheet as of December 31, 2014, and the related consolidated statements of income and partners capital and cash flows for the year then ended, and the related notes to the
consolidated financial statements.

Managements Responsibility for the Financial Statements

Management is responsible for the preparation and fair presentation of these consolidated financial statements in accordance with accounting principles
generally accepted in the United States of America; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of consolidated financial statements that are free from material
misstatement, whether due to fraud or error.

Auditors Responsibility

Our responsibility is to express an opinion on these consolidated financial statements based on our audit. We conducted our audit in accordance with auditing
standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the consolidated financial statements. The procedures
selected depend on the auditors judgment, including the assessment of the risks of material misstatement of the consolidated financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal
control relevant to the entitys preparation and fair presentation of the consolidated financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the entitys internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by
management, as well as evaluating the overall presentation of the consolidated financial statements.

We believe that the audit evidence we have obtained
is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Amboy
Aggregates Joint Venture and Subsidiaries as of December 31, 2014, and the results of their consolidated operations and their consolidated cash flows for the year then ended in accordance with accounting principles generally accepted in the United
States of America.

Other Matter

The consolidated
financial statements as of December 31, 2013 and for the years ending December 31, 2013 and 2012 were not subjected to audit, review, or compilation procedures and, accordingly, we do not express an opinion, a conclusion, nor provide any other
assurance on such statements.

Amboy Aggregates Joint Venture and Subsidiaries

Notes to Consolidated Financial Statements

December 31, 2014, 2013 (unaudited) and 2012 (unaudited)

Note 1Organization and business

Amboy Aggregates (Amboy) was established on January 1, 1989 as an equal Joint Venture between Great Lakes Dredge and Dock
Partnership and Ralph Clayton and Sons Materials, L.P.

Amboy operates principally in one business segment which is to dredge, process,
transport and sell fine aggregate in the New York Metropolitan area.

Note 2Summary of significant accounting policies

Principles of consolidation

On April 27, 2010 Amboy purchased the remaining 50% interest in New York Sand & Stone, LLC (NYS&S) whose
principal business activity is to process and sell fine aggregate and stone in the New York Metropolitan area. The liability of Amboy is limited to Amboys total equity in NYS&S. NYS&S shall terminate no later than July 31, 2027.

During 2006, Amboy formed a wholly-owned subsidiary, Newport, LLC (A Limited Liability Partnership). Since formation, there has been no
activity at Newport, LLC. The consolidated financial statements include the accounts of Amboy, NYS&S and Newport, LLC. All significant intercompany accounts and transactions have been eliminated in consolidation. Amboy, NYS&S and Newport,
LLC are collectively referred to as the Partnership.

On October 21, 2014, the Company sold its 100% interest in NYS&S (see Note
3).

Use of estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect certain reported amounts and disclosures. Accordingly, actual results could differ from those estimates.

Concentration risks

Financial instruments which potentially subject the Partnership to concentrations of credit risk consist principally of cash and accounts
receivable. The Partnership maintains its cash with high credit quality financial institutions. Accounts at these institutions are insured by the Federal Deposit Insurance Company (FDIC) up to $250,000. As of December 31, 2014, the
Partnerships cash balance exceeded the current FDIC insured amount by approximately $9,843,000.

The Partnership generally extends
credit to its customers, a significant portion of which are in the construction industry. During 2014, 2013 and 2012, approximately 62%, 32% (unaudited), and 29% (unaudited), respectively, of the Partnerships net sales were derived from
nonrelated major customers. During 2014 and 2013, three and four customers accounted for 66% and 64% (unaudited) of the Companys gross accounts receivable, respectively.

Notes to Consolidated Financial Statements

December 31, 2014, 2013 (unaudited) and 2012 (unaudited)



The Partnership closely monitors the extension of credit to its customers while maintaining
allowances for potential credit losses. On a periodic basis, the Partnership evaluates its accounts receivable and establishes an allowance for doubtful accounts, based on a history of past write-offs and collections and current credit conditions
and does not have a policy for requiring collateral. Management does not believe that significant credit risk exists at December 31, 2014.

The Partnerships direct labor is supplied primarily by unions, which have collective bargaining agreements. For the years ended
December 31, 2014, 2013 and 2012, 58%, 77% (unaudited) and 76% (unaudited), respectively, of the Partnerships labor force is subject to collective bargaining agreements, which expires on January 31, 2016.

Inventory

Inventory is
stated at the lower of cost, determined using the first-in, first-out (FIFO) method, or market.

Property, plant and equipment

Property, plant and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over
the estimated useful lives of the respective assets.

Impairment of long-lived assets

The Company reviews long-lived assets for impairment whenever events or changes in business circumstances indicate that the carrying amount of
the asset may not be fully recoverable. If facts and circumstances indicate that the Companys long-lived assets might be impaired, the estimated future undiscounted cash flows associated with the long-lived asset would be compared to its
carrying amounts to determine if a write-down to fair value is necessary. If a write-down is required, the amount is determined by estimation of the present value of net discounted cash flows. During the years ended December 31, 2014 and 2013
(unaudited), there were no facts or circumstances that would indicate that the assets may not be fully recoverable.

Permits

Costs incurred in connection with obtaining permits to dredge the Partnerships products are amortized on the straight-line basis over the
term of the related permits. As of December 31, 2014, estimated amortization expense for each of the next five years is $7,055 and $24,690 thereafter.

Revenue recognition

Sales are recognized when revenue is realized or becomes realizable and has been earned. In general, revenue is recognized when the earnings
process is complete and collectability is reasonably assured which is usually upon shipment of the product. Amounts billed related to shipping and handling are included in revenue.

Shipping and handling costs

Shipping and handling costs are included in cost of sales.

Income taxes

Income or
loss of the Partnership is includible in the income tax returns of the partners in proportion to their respective interests. Accordingly, there is no provision for income taxes in the accompanying consolidated financial statements.

The Partnership has no unrecognized tax benefits at December 31, 2014. The Partnerships Federal and state income tax returns prior
to fiscal year 2011 are closed and management continually evaluates expiring statutes of limitations, audits, proposed settlements, changes in tax law and new authoritative rulings.

The Partnership recognizes interest and penalties associated with income tax matters as part of the income tax provision, if applicable, and
includes accrued interest and penalties with the related tax liability in the accompanying consolidated balance sheets.

Reclassification

Certain
amounts in the 2013 and 2012 financial statements have been reclassified to conform to the 2014 presentation.

Subsequent events

The Partnership has evaluated subsequent events through March 27, 2015, which is the date the financial statements were available to be
issued.

Note 3Discontinued operations

In accordance with the membership interest purchase agreement dated October 21, 2014, the Company sold 100% of the interest in NYS&S.
The purchase price was approximately $15,181,000, resulting in a loss on sale of discontinued operations of approximately $2,309,000 reported in the consolidated statement of income and partners capital for the year ended December 31,
2014.

In connection with the sale, proceeds received during 2014 amounted to approximately $11,650,000. The remaining unpaid balance of
the purchase price is held in escrow, to be released to the Company upon certain events. This escrow amount is recorded as restricted cash in the consolidated balance sheet for the year ended December 31, 2014 and will be used towards the
restoration of two piers located at the NYS&S site.

Note 7Due from insurance claim

As of December 31, 2013, the Partnership had been approved by its insurance company for proceeds of $89,141 (unaudited)
related to storm damages. This amount was received in January 2014, and as such, is reflected as receivables as of December 31, 2013.

Note 8Long-term debt

The Partnership has a promissory note payable (the Note) with a former member of NYS&S with remaining
outstanding principal of $4,587,996 as of December 31, 2014. The note, which was secured by interest in NYS&S, contained a covenant prohibiting the sale of the collateral. At December 31, 2014, the Company was in breach of the covenant as a
result of the sale of NYS&S. Under the terms of the agreement, violation of the covenant entitles the holder to accelerate upon notice of the amounts due, which include, in addition to the principal and accrued interest, a yield maintenance fee.
At December 31, 2014, the entire amount of the note, $4,587,996, has been included in current liabilities. In addition, the Company accrued approximately $917,900 representing accrued interest and yield maintenance fee, which is included in the
current portion of long-term debt in the consolidated balance sheet for the year ended December 31, 2014.

Note 9Retirement plans

Pension and annuity plans

Employees covered by a union agreement were included in multi-employer pension and annuity plans to which the Partnership made contributions in
accordance with the contractual union agreement. The Partnership ceased contributions to the Operating Engineers Local No. 825 Pension Plan effective February 19, 2011 and any future contributions were paid to the annuity fund. As a result
of withdrawing from the pension fund, the Partnership was obligated to pay $328,628, plus interest of $47,445, of which $77,687, including interest of $5,834, was paid during 2014 and $58,262, including interest of $7,245, was paid during 2013. At
December 31, 2014 and 2013, other liabilities and accrued expenses included $12,079, and $76,547 and $91,162 (unaudited) and $69,318 (unaudited), respectively, related to this withdrawal obligation.

Principal payment requirements of the withdrawal obligation in each of the years subsequent to December 31, 2014 are as follows:



|                         |  |        |        | 
|------------------------ |  | ------ | ------ | 
|Year Ending
December 31, |  | Amount |       
|2015                     |  | $      | 76,547 | 
|2016                     |  |        | 12,079 | 

The Partnership maintains a retirement plan qualifying under Section 401(k) of the Internal Revenue Code
which allows eligible employees to defer a portion of their income through contributions to the plan. Under the provisions of the plan, the Partnership makes contributions for the benefit of the employees, subject to certain limitations. The
Partnerships contributions for the years ended December 31, 2014, 2013 and 2012 were $63,029, $86,136 (unaudited) and $75,977 (unaudited), respectively.

Multi-employer pension plans

The Partnership contributes to multi-employer pension plans under collective bargaining agreements which provide retirement benefits for its
various union employees. The risks of participating in multi-employer plans are different from single employer plans as assets contributed are available to provide benefits to employees of other employers and unfunded obligations from an employer
that discontinues contributions are the responsibility of all remaining employers. In addition, in the event of a plans termination or the Partnerships withdrawal from a plan, the Partnership may be liable for a portion of the
plans unfunded vested benefits. The Partnership is not aware of any expected plan terminations.

The Partnerships
contributions to these plans were less than 5% of each such plans total contributions. Unless otherwise noted, with regards to the operating Engineers Local No. 825 Pension Plan, the most recent Pension Protection Act zone status
available in 2014 and 2013 is for the plans year-end at June 30, 2014 and 2013, respectively. With regards to the Central Pension Fund of the International Union of Operating Engineers and Participating Employers, the most recent Pension
Protection Act zone status available in 2014 and 2013 is for the Plans year end at January 31, 2015 and January 31, 2014. The zone status is based on information that the Partnership received from the plan and is certified by the
plans actuary. Among other factors, plans in the red zone are generally less than 65% funded, plans in the yellow zone are less than 80% funded and plans in the green zone are at least 80% funded. The FIP/RP Status
Pending/Implemented column indicates plans for which a financial improvement plan (FIP) or a rehabilitation plan (RP) is either pending or has been implemented. Information for significant multi-employer pension plans
in which the Partnership participates is included in the table below:
