Notes to Condensed Consolidated Financial Statements
(unaudited)
Note 1 – Basis of Presentation and Accounting Policies
The condensed consolidated financial statements include the accounts of Matrix Service Company (“Matrix”, “we”, “our”, “us”, “its” or the “Company”) and its subsidiaries, unless otherwise indicated. Intercompany balances and transactions have been eliminated in consolidation.
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with Rule 10-01 of Regulation S-X for interim financial statements required to be filed with the Securities and Exchange Commission and do not include all information and footnotes required by U.S. generally accepted accounting principles ("GAAP") for complete financial statements. The information furnished reflects all adjustments, consisting of normal recurring adjustments, that are, in the opinion of management, necessary for a fair statement of the results of operations, cash flows and financial position for the interim periods presented. The accompanying condensed financial statements should be read in conjunction with the audited financial statements for the year ended June 30, 2017, included in the Company’s Annual Report on Form 10-K for the year then ended. The results of operations for the six month period ended December 31, 2017 may not necessarily be indicative of the results of operations for the full year ending June 30, 2018.
Recently Issued Accounting Standards
Accounting Standards Update 2014-09, Revenue from Contracts with Customers (Topic 606)
On May 28, 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09. The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that “an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.” The ASU also requires entities to disclose both quantitative and qualitative information that enables users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The ASU's disclosure requirements are significantly more comprehensive than those in existing revenue standards. The ASU applies to all contracts with customers except those that are within the scope of other topics in the FASB Accounting Standards Codification ("ASC"). The ASU is effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Early adoption is permitted on a limited basis.
The Company is currently evaluating the impact of adopting the ASU on the Company's financial position, results of operations, cash flows and related disclosures. Adoption of this ASU is expected to affect the manner in which the Company determines the unit of account for its projects (i.e., performance obligations). Under existing guidance, the Company may have multiple performance obligations for large, complex projects. Upon adoption, the Company expects that similar projects may have fewer performance obligations, possibly just one in some cases, which will result in a more constant recognition of revenue and profit over the term of the project. In addition, management expects that profit could be recognized earlier for contract amounts related to unapproved change orders and claims. The Company will adopt this standard on July 1, 2018 using the modified retrospective method of application, which may result in a cumulative effect adjustment to retained earnings as of the date of adoption.
The Company has developed its revised accounting policy for revenue recognition and continues to review its contracts in order to validate the new accounting policy and reassess its processes and internal controls. At this time, we cannot reliably estimate the amount of any potential retrospective adjustment.
Accounting Standards Update 2016-02, Leases (Topic 842)
On February 25, 2016, the FASB issued ASU 2016-02. The amendments in this update require, among other things, that lessees recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Lessees and lessors must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted, but we do not plan to do so at this time.

Notes to Condensed Consolidated Financial Statements
(unaudited)
We are currently evaluating the ASU's expected impact on our financial statements. See Note 8 of Item 8. Financial Statements and Supplementary Data in our 2017 Form 10-K for more information about the timing and amount of future operating lease payments, which we believe is indicative of the materiality of adoption of the ASU to our financial statements.
Accounting Standards Update 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments
On June 16, 2016, the FASB issued ASU 2016-13, which will change how the Company accounts for its allowance for uncollectible accounts. The amendments in this update require a financial asset (or a group of financial assets) to be presented at the net amount expected to be collected. The income statement will reflect any increases or decreases of expected credit losses that have taken place during the period. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount.
Current GAAP delays the recognition of the full amount of credit losses until the loss is probable of occurring. The amendments in this update eliminate the probable initial recognition threshold and, instead, reflect the Company's current estimate of all expected credit losses. In addition, current guidance limits the information the Company may consider in measuring a credit loss to its past events and current conditions. The amendments in this update broaden the information the Company may consider in developing its expected credit loss estimate to include forecasted information.
The amendments in this update are effective for the Company on July 1, 2020 and the Company may early adopt on July 1, 2019. The Company must apply the amendments in this update through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. At this time, the Company does not expect this update to have a material impact to its estimate of the allowance for uncollectible accounts.
Accounting Standards Update 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting
In May 2017, the FASB issued ASU 2017-09 which clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as a modification. Entities should apply the modification accounting guidance if the value, vesting conditions or classification of the award changes. ASU 2017-09 is effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted and prospective application is required. The Company does not expect the adoption of ASU 2017-09 to have a material impact on its financial position, results of operations or cash flows.
Note 2 – Acquisitions
Purchase of Houston Interests, LLC
On December 12, 2016, the Company completed the acquisition of Houston Interests, LLC ("Houston Interests"), a premier global solutions company that provides consulting, engineering, design, construction services and systems integration. Houston Interests brings expertise to the Company in natural gas processing; sulfur recovery, processing and handling; liquid terminals, silos and other bulk storage; process plant design; power generation environmental controls and material handling; industrial power distribution; electrical, instrumentation and controls; marine structures; material handling systems and terminals for cement, sulfur, fertilizer, coal and grain facilities; and process heaters. The business has been included in our Matrix PDM Engineering, Inc. subsidiary, and its operating results impact primarily the Oil Gas & Chemical and Industrial segments.
The Company purchased all of the equity interests of Houston Interests for $42.5 million in cash, net of working capital adjustments and cash acquired. The consideration paid is as follows (in thousands):

Cash paid for equity interest | $ | 46,000 |
Cash paid for working capital | 6,837 |
Less: cash acquired | (10,331 | )
Net purchase price | $ | 42,506 |

- 9-

Table of Contents
The Company funded the equity interest portion of the consideration paid from borrowings under the Company's senior secured revolving credit facility (See Note 5). The purchase of working capital was paid with cash on hand. Cash paid for acquisitions of $39.8 million for the six months ended December 31, 2016 does not reflect $1.0 million of working capital that was paid subsequent to December 31, 2016.
The net purchase price was allocated to the major categories of assets and liabilities based on their estimated fair value at the acquisition date.
The following table summarizes the final net purchase price allocation (in thousands):

Cash | $ | 10,331 |
Accounts receivable | 10,273 |
Costs and estimated earnings in excess of billings on uncompleted contracts | 746 |
Other current assets | 454 |
Current assets | 21,804 |
Property, plant and equipment | 942 |
Goodwill | 35,146 |
Other intangible assets | 10,220 |
Total assets acquired | 68,112 |
Accounts payable | 962 |
Billings on uncompleted contracts in excess of costs and estimated earnings | 11,648 |
Other accrued expenses | 2,475 |
Current liabilities | 15,085 |
Other liabilities | 190 |
Net assets acquired | 52,837 |
Less: cash acquired | 10,331 |
Net purchase price | $ | 42,506 |

The goodwill recognized from the acquisition is primarily attributable to the technical expertise of the acquired workforce and the complementary nature of Houston Interests' operations, which the Company believes will enable the combined entity to expand its service offerings and enter new markets. All of the goodwill recognized is deductible for income tax purposes.
The Company has agreed to pay the previous owners up to $2.6 million for any unused portion of acquired warranty obligations outstanding as of June 30, 2017. This agreement was settled for $1.7 million, which was paid in July 2017. This settlement was reflected as a decrease to the acquired current liabilities and an increase to the net purchase price.
The unaudited financial information in the table below summarizes the combined results of operations of Matrix Service Company and Houston Interests for the three and six months ended December 31, 2016, on a pro forma basis, as though the companies had been combined as of July 1, 2015. The pro forma financial information presented in the table below is for informational purposes only and is not indicative of the results of operations that would have been achieved if the acquisition had taken place at July 1, 2015 nor should it be taken as indicative of future consolidated results of operations.

Table of Contents
The pro forma financial information presented in the table above includes the following adjustments to the combined entities' historical financial statements:

• | Pro forma earnings were adjusted to include $0.4 million and $0.8 million of integration expenses during the three and six months ended December 31, 2016, respectively, that would have been recognized had the acquisition occurred on July 1, 2015.

• | Pro forma earnings were adjusted to include $0.3 million and $0.7 million of interest expense during the three and six months ended December 31, 2016, respectively. The interest was attributable to the assumption that the Company's borrowings of $46.0 million used to fund the net purchase price had been outstanding as of July 1, 2015. This interest was partially offset by the assumption that Houston Interests' former debt was extinguished as of July 1, 2015.

• | Pro forma earnings were adjusted to exclude $0.2 million and $0.3 million of depreciation and intangible asset amortization expense during the three and six months ended December 31, 2016, respectively. This adjustment is due to the recognition of amortizable intangible assets as part of the acquisition and the effect of fair value adjustments to acquired property, plant and equipment.

• | Pro forma earnings were adjusted to include income tax expense of $1.9 million and $3.3 million during the three and six months ended December 31, 2016, respectively. Houston Interests was previously an exempt entity and income taxes were not assessed in its historical financial information.

Note 3 – Uncompleted Contracts
Contract terms of the Company’s construction contracts generally provide for progress billings based on project milestones. The excess of costs incurred and estimated earnings over amounts billed on uncompleted contracts is reported as a current asset. The excess of amounts billed over costs incurred and estimated earnings recognized on uncompleted contracts is reported as a current liability. Gross and net amounts on uncompleted contracts are as follows:

| December 31, 2017 |  | June 30, 2017
| (in thousands)
Costs incurred and estimated earnings recognized on uncompleted contracts | $ | 2,152,981 |  |  | $ | 1,919,054 |

| $ | (2,155 | ) |  | $ | 16,053 |

Progress billings in accounts receivable at December 31, 2017 and June 30, 2017 included retentions to be collected within one year of $32.2 million and $54.3 million, respectively. Contract retentions collectible beyond one year are included in other assets in the condensed consolidated balance sheet and totaled $1.9 million as of June 30, 2017. There were no retentions collectible beyond one year as of December 31, 2017.

We performed our annual goodwill impairment test as of May 31, 2017, which resulted in no impairment. However, the aggregate difference between the fair values of our reporting units and their carrying amounts decreased significantly since the previous year's test as a result of market conditions at that time. The fair value of one reporting unit (carrying value of goodwill of $8.0 million) only exceeded its carrying amount by 9%. The valuation model for this reporting unit assumed the award of a significant project prior to the end of the second fiscal quarter, with project work to commence shortly thereafter. This project award was subsequently obtained during the first fiscal quarter of 2018. Management is not aware of any qualitative indicators of goodwill impairment as of December 31, 2017. The Company will continue to monitor for indicators of impairment and perform additional tests as needed.
Other Intangible Assets
Information on the carrying value of other intangible assets is as follows:

In December 2017, the Company settled a portion of an account receivable with a customer in exchange for $50.0 million of backlog, which the Company expects to recognize as revenue over the next six years. The Company has recognized the backlog as a customer-based intangible asset with an estimated fair value of $2.0 million. The value assigned to the backlog approximated the net book value of the account receivable included in the settlement. The amortization expense will be recognized as the work is completed.
Amortization expense totaled $1.4 million and $3.0 million during the three and six months ended December 31, 2017, respectively, and $1.0 million and $1.8 million during the three and six months ended December 31, 2016, respectively.

Note 5 – Debt
On February 8, 2017, the Company entered into the Fourth Amended and Restated Credit Agreement (the "Credit Agreement"), by and among the Company and certain foreign subsidiaries, as Borrowers, various subsidiaries of the Company, as Guarantors, JPMorgan Chase Bank, N.A., as Administrative Agent, Sole Lead Arranger and Sole Bookrunner, and the other Lenders party thereto.
The Credit Agreement provides for a five-year senior secured revolving credit facility of $300.0 million that expires February 8, 2022. The credit facility may be used for working capital, acquisitions, capital expenditures, issuances of letters of credit and other lawful purposes.
Except as described in the paragraph below for the August 31, 2017 amendment, the Credit Agreement includes the following covenants and borrowing limitations:

• | Our Leverage Ratio, determined as of the end of each fiscal quarter, may not exceed 3.00 to 1.00.

• | We are required to maintain a Fixed Charge Coverage Ratio, determined as of the end of each fiscal quarter, greater than or equal to 1.25 to 1.00.

• | Asset dispositions (other than dispositions in which all of the net cash proceeds therefrom are reinvested into the Company and dispositions of inventory and obsolete or unneeded equipment in the ordinary course of business) are limited to $20.0 million per 12-month period.

The credit facility includes a sub-facility for revolving loans denominated in Australian Dollars, Canadian Dollars, Euros and Pounds Sterling in an aggregate amount not to exceed the U.S. Dollar equivalent of $75.0 million and a $200.0 million sublimit for letters of credit.
Each revolving borrowing under the Credit Agreement will bear interest at a rate per annum equal to:

• | The ABR or the Adjusted LIBO Rate, in the case of revolving loans denominated in U.S. Dollars;

• | The Canadian Prime Rate or the CDOR rate, in the case of revolving loans denominated in Canadian Dollars;

• | The Adjusted LIBO Rate, in the case of revolving loans denominated in Pounds Sterling or Australian Dollars; or

• | The EURIBO Rate, in the case of revolving loans denominated in Euros,

in each case, plus the Applicable Margin, which is based on the Company's Leverage Ratio. The Applicable Margin on ABR loans ranges between 0.625% and 1.625%. The Applicable Margin for Adjusted LIBO, EURIBO and CDOR loans ranges between 1.625% and 2.625% and the Applicable Margin for Canadian Prime Rate loans ranges between 2.125% and 3.125%.

The unused credit facility fee is between 0.25% and 0.45% based on the Leverage Ratio.
The Credit Agreement includes a Leverage Ratio covenant, which provides that Consolidated Funded Indebtedness, as of the end of any fiscal quarter, may not exceed 3.0 times Consolidated EBITDA, as defined in the Credit Agreement, over the previous four quarters. For the four quarters ended December 31, 2017, Consolidated EBITDA was $25.9 million. Consolidated Funded Indebtedness at December 31, 2017 was $77.9 million.
On August 31, 2017, the Company entered in to an amendment to its Credit Agreement, which provided the following:

• | The maximum permitted Leverage Ratio was temporarily increased to 4.00 to 1.00 for the quarters ending September 30, 2017, and December 31, 2017. The maximum Leverage Ratio will revert back to 3.00 to 1.00 beginning with the quarter ending March 31, 2018.

• | The Fixed Charge Coverage Ratio will not be tested for the quarters ending September 30, 2017 and December 31, 2017, but will be in effect and tested quarterly thereafter beginning with the quarter ending March 31, 2018.

• | A new minimum Consolidated EBITDA covenant was added solely for the four-quarter period ending December 31, 2017. For this period, the Company is required to achieve Consolidated EBITDA of $15.0 million.

• | The Restricted Payments covenant was amended to restrict cash dividends and share repurchases during the period beginning August 31, 2017 and ending December 31, 2017 to an aggregate basket of $5.0 million. In addition, during such period, both cash dividends and share repurchases are prohibited unless the pro forma Leverage Ratio is less than or equal to 2.50 to 1.00. Thereafter, the restriction reverts back to limiting cash dividends to 50% of net income for each fiscal year, and limiting share repurchases to $30.0 million per calendar year.

• | An additional increased pricing tier was added for the "Covenant Relief Period" beginning on August 31, 2017 and ending on the date we deliver our financial statements and compliance certificate for the fiscal quarter ending December 31, 2017. If our Leverage Ratio as of any quarterly calculation date during the Covenant Relief Period exceeds 3.00 to 1.00: (1) the Applicable Margin on ABR loans will be 1.875%; (2) the Applicable Margin for Adjusted LIBO, EURIBO and CDOR will be 2.875%; (3) the Applicable Margin for Canadian Prime Rate loans will be 3.375%; and (4) the unused credit facility fee will be 0.50%.

Availability under the senior secured revolving credit facility at December 31, 2017 was as follows:

| December 31, 2017 |  | June 30, 2017
| (In thousands)
Senior secured revolving credit facility | $ | 300,000 |  |  | $ | 300,000 |

Letters of credit | 27,026 |  |  | 7,825 |
Availability under the senior secured revolving credit facility | $ | 25,582 |  |  | $ | 78,401 |

Outstanding borrowings at December 31, 2017 under our Credit Agreement were primarily used to fund the acquisition of Houston Interests (See Note 2) and working capital needs in our Canadian business due to the timing of collections and disbursements on on a major project in the Electrical Infrastructure segment.
At December 31, 2017, the Company was in compliance with all affirmative, negative, and financial covenants under the Credit Agreement.

Note 6 – Income Taxes
We use the asset and liability approach for financial accounting and reporting for income taxes. Deferred income tax assets and liabilities are computed annually for differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances based on our judgments and estimates are established when necessary to reduce deferred tax assets to the amount expected to be realized in future operating results. Company management believes that realization of deferred tax assets in excess of the valuation allowance is more likely than not. Our estimates are based on facts and circumstances in existence as well as interpretations of existing tax regulations and laws applied to the facts and circumstances.
The Company provides for income taxes regardless of whether it has received a tax assessment. Taxes are provided when it is considered probable that additional taxes will be due in excess of amounts included in the tax return. The Company regularly reviews exposure to additional income taxes due, and as further information is known or events occur, adjustments may be recorded.
Tax Cuts and Jobs Act
The Tax Cuts and Jobs Act (the "Act") was enacted on December 22, 2017. The Act makes broad and complex changes to the U.S. tax code, which have affected our current results and will affect our future results. The following are significant changes in the tax code that are effective for the Company beginning January 1, 2018:

• | reducing the Company's U.S. federal corporate income tax rate from 35% to a blended rate of 28.06% for fiscal 2018 as stipulated by the Internal Revenue Code for companies using a June 30th fiscal year end and to 21% for fiscal years thereafter;

• | generally eliminating U.S. federal income tax on dividends from foreign subsidiaries;

• | requiring current inclusion in U.S. federal taxable income of certain earnings of controlled foreign corporations;

• | allowing full expensing of certain assets placed in service from September 27, 2017 and before January 1, 2023;

• | restricting further deductibility of executive performance compensation in excess of $1.0 million; and

• | disallowing certain entertainment expenses.

The following are significant changes in the tax code that are effective for the Company beginning July 1, 2018:

• | eliminating the deduction for domestic production activity;

• | limiting the annual deduction for business interest;

• | taxing global intangible low-tax income;

• | allowing a deduction for domestically earned foreign intangible income; and

• | establishing a new base erosion and anti-abuse tax on payments between U.S. taxpayers and foreign related parties.

As of December 31, 2017 we have not completed our accounting for the tax effects of the Act. However, in certain cases as described below, we have made a reasonable estimate of the effects on our existing deferred tax balances and the one-time transition tax. In other cases, we have not been able to make a reasonable estimate and continue to account for those items based on our existing accounting under ASC 740.

One-time Transition Tax on Unrepatriated Earnings of Certain Foreign Subsidiaries
The Act includes a one-time transition tax based on our total post-1986 foreign earnings and profits (E&P) for which we have previously deferred from U.S. income taxes. We have not completed in its entirety the calculations surrounding this tax, but based on our preliminary calculations, our foreign subsidiaries have overall negative E&P. Therefore, we do not anticipate incurring tax related to this provision of the Act since any return of assets would be a return of capital, not earnings. Due to the preliminary nature of our calculations, no additional income taxes have been provided for any remaining undistributed foreign earnings not subject to the transition tax and any outside basis difference inherent in these entities as these amounts continue to be indefinitely reinvested in foreign operations.
Deferred Taxes Remeasurement
We remeasured our domestic deferred tax assets and liabilities based on the rates at which we expect them to reverse in the future. Section 15 of the Internal Revenue Code stipulates that our fiscal year ending June 30, 2018 will have a blended U.S. federal corporate income tax rate of 28.06%, which is based on the applicable tax rates before and after the Act and the number of days in the tax year. Therefore, domestic deferred taxes reversing prior to July 1, 2018 will be taxed based on the blended rate and reversals occurring thereafter will be taxed at the new 21% tax rate. Our domestic subsidiaries had a net deferred tax liability position as of December 31, 2017, which resulted in a $1.2 million remeasurement reduction of our domestic net deferred tax liabilities. This remeasurement adjustment was based on our best estimate of the timing of our deferred tax reversals. As a fiscal year taxpayer, the timing of the reversal of certain deferred tax assets and liabilities during this fiscal year and beyond is uncertain. Although we have made a reasonable estimate as of December 31, 2017, we will continue to analyze certain aspects of the Act and refine our calculations, which could potentially affect the measurement of our deferred tax balances.
Effective Tax Rate
Our effective tax rate for the three and six months ended December 31, 2017 was (5.8)% and 25.2% compared to 32.8% and 33.3% in the same period last year. The effective tax rates in fiscal 2018 were positively impacted by the $1.2 million deferred taxes remeasurement adjustment discussed in the previous paragraph and the use of the lower blended U.S. corporate income tax rate, which resulted in a benefit of $0.7 million, of which $0.5 million related to the remeasurement of the first quarter.
Note 7 – Commitments and Contingencies
Insurance Reserves
The Company maintains insurance coverage for various aspects of its operations. However, exposure to potential losses is retained through the use of deductibles, self-insured retentions and coverage limits.
Typically our contracts require us to indemnify our customers for injury, damage or loss arising from the performance of our services and provide warranties for materials and workmanship. The Company may also be required to name the customer as an additional insured up to the limits of insurance available, or we may be required to purchase special insurance policies or surety bonds for specific customers or provide letters of credit in lieu of bonds to satisfy performance and financial guarantees on some projects. Matrix maintains a performance and payment bonding line sufficient to support the business. The Company generally requires its subcontractors to indemnify the Company and the Company’s customer and name the Company as an additional insured for activities arising out of the subcontractors’ work. We also require certain subcontractors to provide additional insurance policies, including surety bonds in favor of the Company, to secure the subcontractors’ work or as required by the subcontract.
There can be no assurance that our insurance and the additional insurance coverage provided by our subcontractors will fully protect us against a valid claim or loss under the contracts with our customers.
Unapproved Change Orders and Claims
Costs and estimated earnings in excess of billings on uncompleted contracts included revenues for unapproved change orders and claims of $10.5 million at December 31, 2017 and $11.0 million at June 30, 2017. Generally, collection of amounts related to unapproved change orders and claims is expected within twelve months. However, since customers may not pay these amounts until final resolution of related claims, collection of these amounts may extend beyond one year.

The Company and its subsidiaries are participants in various legal actions. It is the opinion of management that none of the known legal actions will have a material impact on the Company’s financial position, results of operations or liquidity.
Note 8 – Earnings per Common Share
Basic earnings per share (“Basic EPS”) is calculated based on the weighted average shares outstanding during the period. Diluted earnings per share (“Diluted EPS”) includes the dilutive effect of stock options and nonvested deferred shares.
The computation of basic and diluted earnings per share is as follows:

| Three Months Ended |  | Six Months Ended
| December 31, 2017 |  | December 31, 2016 |  | December 31, 2017 |  | December 31, 2016

Also included in the Storage Solutions segment is work related to specialty storage tanks, including liquefied natural gas (“LNG”), liquid nitrogen/liquid oxygen (“LIN/LOX”), liquid petroleum (“LPG”) tanks and other specialty vessels, including spheres. Finally, we offer AST products, including geodesic domes, aluminum internal floating roofs, floating suction and skimmer systems, roof drain systems and floating roof seals.
The Industrial segment primarily includes construction and maintenance work in the iron and steel, mining and minerals, and agricultural industries. Our work in the iron and steel industry is primarily for customers engaged in the production of raw steel. Our work in the mining and minerals industry is primarily for customers engaged in the extraction of copper. Our work in the agricultural industry includes the engineering and design of grain silos, docks and handling systems; the design of control system automation and materials handling for the food industry; and engineering, construction, process design and balance of plant work for fertilizer production facilities. We also perform work in bulk material handling, thermal vacuum chambers, and other industrial markets.
The Company evaluates performance and allocates resources based on operating income. The accounting policies of the reportable segments are the same as those described in the Summary of Significant Accounting Policies footnote included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2017. Intersegment sales and transfers are recorded at cost; therefore, no intersegment profit or loss is recognized.
Segment assets consist primarily of cash and cash equivalents, accounts receivable, costs and estimated earnings in excess of billings on uncompleted contracts, property, plant and equipment, goodwill and other intangible assets.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
CRITICAL ACCOUNTING ESTIMATES
There have been no material changes in our critical accounting policies from those reported in our fiscal 2017 Annual Report on Form 10-K filed with the SEC. For more information on our critical accounting policies, see Part II, Item 7 of our fiscal 2017 Annual Report on Form 10-K. The following section provides certain information with respect to our critical accounting estimates as of the close of our most recent quarterly period.
Revenue Recognition
Matrix records revenue on fixed-price contracts on a percentage-of-completion basis, primarily based on costs incurred to date compared to the total estimated cost. The Company records revenue on cost-plus and time-and-material contracts on a proportional performance basis as costs are incurred. Contracts in process are valued at cost plus accrued profits less billings on uncompleted contracts. Contracts are generally considered substantially complete when field construction is completed. The elapsed time from award of a contract to completion of performance may be in excess of one year. Matrix includes pass-through revenue and costs on cost-plus contracts, which are customer-reimbursable materials, equipment and subcontractor costs, when Matrix determines that it is responsible for the procurement and management of such cost components.
Matrix has numerous contracts that are in various stages of completion, which require estimates to determine the appropriate cost and revenue recognition. The Company has a history of making reasonably dependable estimates of the extent of progress towards completion, contract revenues and contract costs, and accordingly, does not believe significant fluctuations are likely to materialize. However, current estimates may be revised as additional information becomes available. If estimates of costs to complete fixed-price contracts indicate a loss, a provision is made through a contract write-down for the total loss anticipated. A number of our contracts contain various cost and performance incentives and penalties that impact the earnings we realize from our contracts. Adjustments related to these incentives and penalties are recorded in the period on a percentage of completion basis when estimable and probable.
Indirect costs, such as salaries and benefits, supplies and tools, equipment costs and insurance costs, are charged to projects based upon direct labor hours and overhead allocation rates per direct labor hour or a percentage of cost incurred. Warranty costs are normally incurred prior to project completion and are charged to project costs as they are incurred. Warranty costs incurred subsequent to project completion were not material for the periods presented. Overhead allocation rates are established annually during the budgeting process and evaluated for accuracy throughout the year based upon actual direct labor hours and actual costs incurred.
Goodwill
We perform our annual impairment test in the fourth quarter of each fiscal year to determine whether an impairment exists and to determine the amount of headroom. We define "headroom" as the percentage difference between the fair value of a reporting unit and its carrying value. We performed our annual goodwill impairment test as of May 31, 2017, which resulted in no impairment. However, the aggregate headroom between the fair values of our reporting units and their carrying amounts decreased significantly since the previous year's test as a result of market conditions at that time. The fair value of one reporting unit (carrying value of goodwill of $8.0 million) only exceeded its carrying amount by 9%. The valuation model for this reporting unit assumed the award of a significant project prior to the end of the second fiscal quarter, with project work to commence shortly thereafter. This project award was subsequently obtained during the first fiscal quarter of 2018, which resolved the previous contingency. The amount of headroom varies by reporting unit. Approximately 37% of our goodwill balance at May 31, 2017 was attributable to one reporting unit. This unit had headroom of 24%. The remaining goodwill was attributable to nine reporting units, with headroom of between 7% and 172%. Management is not aware of any qualitative indicators of goodwill impairment as of December 31, 2017. The Company will continue to monitor for indicators of impairment and perform additional tests as needed.
Management utilizes a discounted cash flow analysis, referred to as an income approach, and market multiples of EBITDA to determine the estimated fair value of our reporting units. Significant judgments and assumptions including forecasted project awards, discount rate, anticipated revenue growth rate, gross margins, operating expenses, working capital needs and capital expenditures are inherent in these fair value estimates, which are based on our operating and capital budgets and on our strategic plan. As a result, actual results may differ from the estimates utilized in our income approach. The use of alternate judgments and/or assumptions could result in a fair value that differs from our estimate and could result in the recognition of an impairment charge in the financial statements. As a result of these uncertainties, we utilize multiple scenarios and assign probabilities to each of the scenarios in the income approach. We also compare the combined carrying values and combined estimated fair values of our reporting units to our market capitalization for reasonableness.

Other Intangible Assets
Intangible assets that have finite useful lives are amortized by the straight-line method over their useful lives ranging from 4 to 15 years. The Company evaluates intangible assets with finite lives for impairment whenever events or circumstances indicate that the carrying value may not be recoverable. The Company did not observe any events or circumstances during the six months ended December 31, 2017 that would indicate that the carrying value of its intangible assets may not be recoverable.
Unapproved Change Orders and Claims
Costs and estimated earnings in excess of billings on uncompleted contracts included revenues for unapproved change orders and claims of $10.5 million at December 31, 2017 and $11.0 million at June 30, 2017. The amounts ultimately realized may be significantly different than the recorded amounts resulting in a material adjustment to future earnings.
Insurance Reserves
We maintain insurance coverage for various aspects of our operations. However, we retain exposure to potential losses through the use of deductibles, self-insured retentions and coverage limits. We establish reserves for claims using a combination of actuarially determined estimates and management judgments on a case-by-case basis and update our evaluations as further information becomes known. Judgments and assumptions, including the assumed losses for claims incurred but not reported, are inherent in our reserve accruals; as a result, changes in assumptions or claims experience could result in changes to these estimates in the future. If actual results of claim settlements are different than the amounts estimated, we may be exposed to gains and losses that could be significant.
Recently Issued Accounting Standards
Accounting Standards Update 2014-09, Revenue from Contracts with Customers (Topic 606)
On May 28, 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09. The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that “an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.” The ASU also requires entities to disclose both quantitative and qualitative information that enables users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The ASU's disclosure requirements are significantly more comprehensive than those in existing revenue standards. The ASU applies to all contracts with customers except those that are within the scope of other topics in the FASB Accounting Standards Codification ("ASC"). The ASU is effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Early adoption is permitted on a limited basis.
The Company is currently evaluating the impact of adopting the ASU on the Company's financial position, results of operations, cash flows and related disclosures. Adoption of this ASU is expected to affect the manner in which the Company determines the unit of account for its projects (i.e., performance obligations). Under existing guidance, the Company may have multiple performance obligations for large, complex projects. Upon adoption, the Company expects that similar projects may have fewer performance obligations, possibly just one in some cases, which will result in a more constant recognition of revenue and profit over the term of the project. In addition, management expects that profit could be recognized earlier for contract amounts related to unapproved change orders and claims. The Company will adopt this standard on July 1, 2018 using the modified retrospective method of application, which may result in a cumulative effect adjustment to retained earnings as of the date of adoption.
The Company has developed its revised accounting policy for revenue recognition and continues to review its contracts in order to validate the new accounting policy and reassess its processes and internal controls. At this time, we cannot reliably estimate the amount of any potential retrospective adjustment.
Accounting Standards Update 2016-02, Leases (Topic 842)
On February 25, 2016, the FASB issued ASU 2016-02. The amendments in this update require, among other things, that lessees recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Lessees and lessors must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted, but we do not plan to do so at this time.
- 21-

Table of Contents
We are currently evaluating the ASU's expected impact on our financial statements. See Note 8 of Item 8. Financial Statements and Supplementary Data in our 2017 Form 10-K for more information about the timing and amount of future operating lease payments, which we believe is indicative of the materiality of adoption of the ASU to our financial statements.
Accounting Standards Update 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments
On June 16, 2016, the FASB issued ASU 2016-13, which will change how the Company accounts for its allowance for uncollectible accounts. The amendments in this update require a financial asset (or a group of financial assets) to be presented at the net amount expected to be collected. The income statement will reflect any increases or decreases of expected credit losses that have taken place during the period. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount.
Current GAAP delays the recognition of the full amount of credit losses until the loss is probable of occurring. The amendments in this update eliminate the probable initial recognition threshold and, instead, reflect the Company's current estimate of all expected credit losses. In addition, current guidance limits the information the Company may consider in measuring a credit loss to its past events and current conditions. The amendments in this update broaden the information the Company may consider in developing its expected credit loss estimate to include forecasted information.
The amendments in this update are effective for the Company on July 1, 2020 and the Company may early adopt on July 1, 2019. The Company must apply the amendments in this update through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. At this time, the Company does not expect this update to have a material impact to its estimate of the allowance for uncollectible accounts.
Accounting Standards Update 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting
In May 2017, the FASB issued ASU 2017-09 which clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as a modification. Entities should apply the modification accounting guidance if the value, vesting conditions or classification of the award changes. ASU 2017-09 is effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted and prospective application is required. The Company does not expect the adoption of ASU 2017-09 to have a material impact on its financial position, results of operations or cash flows.

RESULTS OF OPERATIONS
Overview
We operate our business through four reportable segments: Electrical Infrastructure, Oil Gas & Chemical, Storage Solutions, and Industrial.
The Electrical Infrastructure segment primarily encompasses high voltage services to investor owned utilities, including construction of new substations, upgrades of existing substations, short-run transmission line installations, distribution upgrades and maintenance, and storm restoration services. We also provide construction and maintenance services to a variety of power generation facilities, such as combined cycle plants, and natural gas fired power stations.
The Oil Gas & Chemical segment includes turnaround activities, plant maintenance, engineering and construction in primarily the downstream and midstream petroleum industries. Our customers in these industries are engaged in refining crude oil and processing, fractionating, and marketing of natural gas and natural gas liquids. Another offering is industrial cleaning services, which include hydroblasting, hydroexcavating, chemical cleaning and vacuum services. We also perform work in the petrochemical, upstream petroleum, and sulfur extraction, recovery and processing markets.
The Storage Solutions segment includes new construction of crude and refined products aboveground storage tanks (“ASTs”), as well as planned and emergency maintenance services. The Storage Solutions segment also includes balance of plant work in storage terminals and tank farms. Also included in the Storage Solutions segment is work related to specialty storage tanks, including liquefied natural gas (“LNG”), liquid nitrogen/liquid oxygen (“LIN/LOX”), liquid petroleum (“LPG”) tanks and other specialty vessels, including spheres. Finally, we offer AST products, including geodesic domes, aluminum internal floating roofs, floating suction and skimmer systems, roof drain systems and floating roof seals.
The Industrial segment primarily includes construction and maintenance work in the iron and steel, mining and minerals, and agricultural industries. Our work in the iron and steel industry is primarily for customers engaged in the production of raw steel. Our work in the mining and minerals industry is primarily for customers engaged in the extraction of copper. Our work in the agricultural industry includes the engineering and design of grain silos, docks and handling systems; the design of control system automation and materials handling for the food industry; and engineering, construction, process design and balance of plant work for fertilizer production facilities. We also perform work in bulk material handling, thermal vacuum chambers, and other industrial markets.
Three Months Ended December 31, 2017 Compared to the Three Months Ended December 31, 2016
Consolidated
Consolidated revenue was $282.9 million for the three months ended December 31, 2017, compared to $312.7 million in the same period in the prior fiscal year. On a segment basis, consolidated revenue decreased in the Storage Solutions and Electrical Infrastructure segments by $58.4 million and $38.3 million, respectively. These decreases were partially offset by increases in consolidated revenue for the Industrial and Oil Gas & Chemical segments of $34.2 million and $32.7 million.
Consolidated gross profit decreased from $28.2 million in the three months ended December 31, 2016 to $26.7 million in the three months ended December 31, 2017. Gross margin increased to 9.4% in the three months ended December 31, 2017 compared to 9.0% in the same period in the prior fiscal year. The increase in gross margin in fiscal 2018 is primarily attributable to improved construction overhead cost recovery.
Consolidated SG&A expenses were $21.5 million in the three months ended December 31, 2017 compared to $20.0 million in the same period a year earlier. The increase in fiscal 2018 is primarily attributable to overhead and amortization on intangible assets associated with the December 2016 acquisition of Houston Interests, LLC ("Houston Interests", see Item 1. Financial Statements, Note 2 - Acquisitions) that expanded the Company's engineering business.
Net interest expense was $0.8 million and $0.5 million in the three months ended December 31, 2017 and 2016, respectively. The higher interest expense in fiscal 2018 is primarily attributable to the higher average debt balance in the current year, which is largely attributable to the borrowings used to fund the Houston Interests acquisition, which was completed in December 2016, and borrowings due to the timing of collections and disbursements on a major project in the Electrical Infrastructure segment.

Table of Contents
Our effective tax rate for the three months ended December 31, 2017 was (5.8)% compared to 32.8% in the same period last year. The effective tax rates in fiscal 2018 were positively impacted by a $1.2 million deferred taxes remeasurement adjustment (see Item 1. Financial Statements, Note - 6 Income Taxes) and the use of the lower blended U.S. corporate income tax rate, which resulted in a benefit of $0.7 million, of which $0.5 million related to the remeasurement of the first quarter. We expect our effective tax rate to be 32% for the remainder of fiscal 2018.
For the three months ended December 31, 2017, net income and the related fully diluted earnings per share were $4.5 million and $0.17, respectively, compared to net income and related fully diluted earnings per share of $5.3 million and $0.20, respectively, in the same period a year earlier.
Electrical Infrastructure
Revenue for the Electrical Infrastructure segment decreased $38.3 million to $64.9 million in the three months ended December 31, 2017 compared to $103.2 million in the same period a year earlier. The decrease is due to a combination of a reduction in high voltage revenue and revenue associated with the construction of a large power generating facility in the prior year. The segment gross margin of 8.5% in fiscal 2018 was impacted by increased under recovery of construction overhead costs due to lower volumes in the current fiscal year and increased competition, which led to lower direct margins. The fiscal 2017 segment gross margin was 7.0% during the same period, which was impacted by a settlement adjustment on the power generating facility project.
Oil Gas & Chemical
Revenue for the Oil Gas & Chemical segment was $88.4 million in the three months ended December 31, 2017 compared to $55.7 million in the same period a year earlier. The increase of $32.7 million is primarily attributable to higher turnaround, maintenance and construction volumes. The segment gross margin was 13.3% for the three months ended December 31, 2017 compared to 4.4% in the same period last year. The segment gross margin for fiscal 2018 was positively impacted by strong project execution, project closeouts, higher margin work associated with the Houston Interests acquisition, and improved recovery of construction overhead costs. Fiscal 2017 gross margin was negatively impacted by project execution issues and lower volume which led to higher under recovery of construction overhead costs.
Storage Solutions
Revenue for the Storage Solutions segment was $70.4 million in the three months ended December 31, 2017 compared to $128.8 million in the same period a year earlier, a decrease of $58.4 million. The decrease in segment revenue is primarily a result of delays in project awards which have not allowed the Company to replace higher revenue experienced in the prior year in connection with work on the construction of crude gathering terminals for the Dakota Access pipeline. The segment gross margin was 7.5% in the three months ended December 31, 2017 and 13.3% in the three months ended December 31, 2016. The lower segment gross margin in fiscal 2018 is primarily attributable to higher mix of lower margin work.
Industrial
Revenue for the Industrial segment increased $34.2 million to $59.2 million in the three months ended December 31, 2017 compared to $25.0 million in the same period a year earlier. The increase in revenue is primarily attributable to higher business volumes in the iron and steel industry. The segment gross margin was 6.9% in the three months ended December 31, 2017 compared to 5.9% in the same period a year earlier. The fiscal 2018 segment gross margin was positively impacted by higher volumes, which when combined with previously executed targeted cost reduction, led to improved recovery of construction overhead costs. Additionally, the Company recorded a $0.9 million project settlement with a customer, which reduced gross profit.
Six Months Ended December 31, 2017 Compared to the Six Months Ended December 31, 2016
Consolidated
Consolidated revenue was $552.8 million for the six months ended December 31, 2017, compared to $654.4 million in the same period in the prior fiscal year. On a segment basis, consolidated revenue decreased in the Storage Solutions and Electrical Infrastructure segments by $186.8 million and $46.4 million, respectively. These decreases were partially offset by increases in consolidated revenue for the Oil Gas & Chemical and Industrial segments of $85.8 million and $45.8 million.

Table of Contents
Consolidated gross profit decreased from $60.5 million in the six months ended December 31, 2016 to $55.6 million in the six months ended December 31, 2017. Gross margin increased to 10.1% in the six months ended December 31, 2017 compared to 9.2% in the same period in the prior fiscal year. The increase in gross margin in fiscal 2018 is primarily attributable to strong project execution as well as improved construction overhead cost recovery.
Consolidated SG&A expenses were $43.1 million in the six months ended December 31, 2017 compared to $38.0 million in the same period a year earlier. The increase in fiscal 2018 is primarily attributable to overhead and amortization on intangible assets associated with the December 2016 acquisition of Houston Interests that expanded the Company's engineering business.
Net interest expense was $1.3 million and $0.7 million in the six months ended December 31, 2017 and 2016, respectively. The higher interest expense in fiscal 2018 is primarily attributable to the higher average debt balance in the current year, which is largely attributable to the borrowings used to fund the Houston Interests acquisition, which was completed in December 2016, and borrowings due to the timing of collections and disbursements on a major project in the Electrical Infrastructure segment.
Our effective tax rate for the six months ended December 31, 2017 was 25.2% compared to 33.3% in the same period last year. The effective tax rates in fiscal 2018 were positively impacted by a $1.2 million deferred taxes remeasurement adjustment (see Item 1. Financial Statements, Note - 6 Income Taxes) and the use of the lower blended U.S. corporate income tax rate, which resulted in a benefit of $0.7 million, of which $0.5 million related to the remeasurement of the first quarter. We expect our effective tax rate to be 32% for the remainder of fiscal 2018.
For the six months ended December 31, 2017, net income and the related fully diluted earnings per share were $8.4 million and $0.31, respectively, compared to net income and related fully diluted earnings per share of $14.6 million and $0.54, respectively, in the same period a year earlier.
Electrical Infrastructure
Revenue for the Electrical Infrastructure segment decreased $46.4 million to $144.8 million in the six months ended December 31, 2017 compared to $191.2 million in the same period a year earlier. The decrease is due to a combination of a reduction in high voltage revenue and revenue associated with the construction of a large power generating facility in the prior year. The segment gross margin of 9.5% in fiscal 2018 was impacted by increased under recovery of construction overhead costs due to lower volumes in the current fiscal year and increased competition, which led to lower direct margins. The fiscal 2017 segment gross margin was 6.5% during the same period, which was impacted by a settlement adjustment on the power generating facility project.
Oil Gas & Chemical
Revenue for the Oil Gas & Chemical segment was $174.1 million in the six months ended December 31, 2017 compared to $88.3 million in the same period a year earlier. The increase of $85.8 million is primarily attributable to higher turnaround, maintenance and construction volumes. The segment gross margin was 13.1% for the six months ended December 31, 2017 compared to 2.8% in the same period last year. The segment gross margin for fiscal 2018 was positively impacted by strong project execution, project closeouts, higher margin work associated with the Houston Interests acquisition, and improved recovery of construction overhead costs. Fiscal 2017 gross margin was negatively impacted by project execution issues and lower volume which led to higher under recovery of construction overhead costs.
Storage Solutions
Revenue for the Storage Solutions segment was $141.5 million in the six months ended December 31, 2017 compared to $328.3 million in the same period a year earlier, a decrease of $186.8 million. The decrease in segment revenue is primarily a result of delays in project awards which have not allowed the Company to replace higher revenue experienced in the prior year in connection with work on the construction of crude gathering terminals for the Dakota Access pipeline. The segment gross margin was 9.1% in the six months ended December 31, 2017 and 13.3% in the six months ended December 31, 2016. The lower segment gross margin in fiscal 2018 is primarily attributable to higher mix of lower margin work.

Industrial
Revenue for the Industrial segment increased $45.8 million to $92.5 million in the six months ended December 31, 2017 compared to $46.7 million in the same period a year earlier. The increase in revenue is primarily attributable to higher business volumes in the iron and steel industry. The segment gross margin was 6.6% in the six months ended December 31, 2017 compared to 4.4% in the same period a year earlier. The fiscal 2018 segment gross margin was positively impacted by higher volumes, which when combined with previously executed targeted cost reduction, led to improved recovery of construction overhead costs. Additionally, the Company recorded a $0.9 million project settlement with a customer, which reduced gross profit.
Backlog
We define backlog as the total dollar amount of revenue that we expect to recognize as a result of performing work that has been awarded to us through a signed contract, notice to proceed or other type of assurance that we consider firm. The following arrangements are considered firm:

• | fixed-price awards;

• | minimum customer commitments on cost plus arrangements; and

• | certain time and material arrangements in which the estimated value is firm or can be estimated with a reasonable amount of certainty in both timing and amounts.

For long-term maintenance contracts with no minimum commitments and other established customer arrangements, we include only the amounts that we expect to recognize into revenue over the next 12 months. For all other arrangements, we calculate backlog as the estimated contract amount less revenue recognized as of the reporting date.
The following table provides a summary of changes in our backlog for the three months ended December 31, 2017:

The change in backlog in the Electrical Infrastructure segment during the six months ended December 31, 2017 is mainly attributable to work related to a major power generation project partially offset by high voltage awards.
The change in backlog in the Oil, Gas & Chemical segment during the six months ended December 31, 2017 is mainly attributable to progress on previously announced awards, partially offset by new project awards.
The change in backlog in the Storage Solutions segment during the six months ended December 31, 2017 is attributable to increased project awards, partially offset by progress on previously announced awards. We are seeing an increase in project awards in our Storage Solutions segment as our customers are beginning to respond to an increasingly favorable commodity price environment.
The increase in backlog in the Industrial segment during the six months ended December 31, 2017 is primarily attributable to significant awards for capital projects and maintenance work in the iron and steel industry.
Seasonality and Other Factors
Our operating results can exhibit seasonal fluctuations, especially in our Oil Gas & Chemical segment, for a variety of reasons. Turnarounds and planned outages at customer facilities are typically scheduled in the spring and the fall when the demand for energy is lower. Within the Electrical Infrastructure segment, transmission and distribution work is generally scheduled by the public utilities when the demand for electricity is at its lowest. Therefore, revenue volume in the summer months is typically lower than in other periods throughout the year. Also, we typically see a lower level of operating activity relating to construction projects during the winter months and early in the calendar year because many of our customers’ capital budgets have not been finalized. Our business can also be affected, both positively and negatively, by seasonal factors such as energy demand or weather conditions including hurricanes, snowstorms, and abnormally low or high temperatures. Some of these seasonal factors may cause some of our offices and projects to close or reduce activities temporarily. In addition to the above noted factors, the general timing of project starts and completions could exhibit significant fluctuations. Accordingly, results for any interim period may not necessarily be indicative of operating results for the full year.
Other factors impacting operating results in all segments come from work site permitting delays or customers accelerating or postponing work. The differing types, sizes, and durations of our contracts, combined with their geographic diversity and stages of completion, often results in fluctuations in the Company's operating results.
Impact of Commodity Price Volatility and Market Uncertainty
The prolonged decline in crude oil prices beginning in late 2014 has caused sustained uncertainty in the energy industry, which although improving, continues to negatively impact our results, particularly in the Storage Solutions segment. Since the beginning of fiscal 2018, the price of West Texas Intermediate Crude Oil has increased over 30%, which is a positive development for our customers in both the Storage Solutions and Oil Gas & Chemical segments. With the increasing price of crude oil, we are seeing increased awards, particularly in the Storage Solutions segment. However, our customers' spending tends to lag the price movements of crude oil and other commodities due to budget cycles and the long-term nature of planning for capital projects, especially large capital projects.
In the Industrial segment, our iron and steel customers have increased maintenance spending and resumed major capital projects in response to improving business conditions led by rising steel prices, stronger U.S. economy and a weaker U.S. Dollar. In the mining and minerals markets, copper prices have continued to increase. As a result, we are seeing increased bidding activity, but we have not yet seen a corresponding increase in project awards.
We do not expect fluctuation in commodity prices to have a significant impact on the Electrical Infrastructure segment.
Non-GAAP Financial Measure
EBITDA is a supplemental, non-GAAP financial measure. EBITDA is defined as earnings before interest expense, income taxes, depreciation and amortization. We have presented EBITDA because it is used by the financial community as a method of measuring our performance and of evaluating the market value of companies considered to be in similar businesses. We believe that the line item on our Consolidated Statements of Income entitled “Net Income” is the most directly comparable GAAP measure to EBITDA. Since EBITDA is not a measure of performance calculated in accordance with GAAP, it should not be considered in isolation of, or as a substitute for, net earnings as an indicator of operating performance. EBITDA, as we calculate it, may not be comparable to similarly titled measures employed by other companies. In addition, this measure is not a measure of our ability to fund our cash needs. As EBITDA excludes certain financial information compared with net income, the most directly comparable GAAP financial measure, users of this financial information should consider the type of events and transactions that are excluded. Our non-GAAP performance measure, EBITDA, has certain material limitations as follows:
- 27-

Table of Contents

• | It does not include interest expense. Because we have borrowed money to finance our operations and acquisitions, pay commitment fees to maintain our credit facility, and incur fees to issue letters of credit under the credit facility, interest expense is a necessary and ongoing part of our costs and has assisted us in generating revenue. Therefore, any measure that excludes interest expense has material limitations.

• | It does not include income taxes. Because the payment of income taxes is a necessary and ongoing part of our operations, any measure that excludes income taxes has material limitations.

• | It does not include depreciation or amortization expense. Because we use capital and intangible assets to generate revenue, depreciation and amortization expense is a necessary element of our cost structure. Therefore, any measure that excludes depreciation or amortization expense has material limitations.

A reconciliation of EBITDA to net income follows:

FINANCIAL CONDITION AND LIQUIDITY
Overview
We define liquidity as the ongoing ability to pay our liabilities as they become due, fund business operations and meet all monetary contractual obligations. Our primary sources of liquidity for the six months ended December 31, 2017 were cash on hand, capacity under our senior secured revolving credit facility and cash generated from operations before consideration of changes in working capital. Cash on hand at December 31, 2017 totaled $74.1 million and availability under the senior secured revolving credit facility totaled $25.6 million resulting in available liquidity of $99.7 million as of December 31, 2017 compared to $122.2 million as of June 30, 2017. The decrease in liquidity is primarily attributable to an increase in the capacity constraint relating to the leverage ratio financial covenant under the senior secured revolving credit facility triggered by the Company's financial performance during the last four quarters along with an increase in project related letters of credit.
The Company's liquidity continues to be adequate to support its long-term strategic growth plans. The Company expects liquidity to begin to improve as we work through the third and fourth quarters of fiscal 2018. Since December 31, 2017, the Company's liquidity has strengthened as the Company repaid $35.0 million of borrowings under the senior secured revolving credit facility while maintaining a cash balance in excess of $60.0 million. A complete discussion of our credit agreement is provided under the caption "Senior Secured Revolving Credit Facility" included in this Financial Condition and Liquidity section of the Form 10-Q.
Factors that routinely impact our short-term liquidity and may impact our long-term liquidity include, but are not limited to:

• | Changes in costs and estimated earnings in excess of billings on uncompleted contracts and billings on uncompleted contracts in excess of costs due to contract terms that determine the timing of billings to customers and the collection of those billings

• | Some cost plus and fixed price customer contracts are billed based on milestones which may require us to incur significant expenditures prior to collections from our customers.

• | Time and material contracts are normally billed in arrears. Therefore, we are routinely required to carry these costs until they can be billed and collected.

• | Some of our large construction projects may require security in the form of letters of credit or significant retentions. The timing of collection of retentions is often uncertain.

• | Other changes in working capital

Table of Contents

• | Capital expenditures

Other factors that may impact both short and long-term liquidity include:

• | Acquisitions of new businesses

• | Strategic investments in new operations

• | Purchases of shares under our stock buyback program

• | Contract disputes which can be significant

• | Collection issues, including those caused by weak commodity prices or other factors which can lead to credit deterioration of our customers

• | Capacity constraints under our credit facility and remaining in compliance with all covenants contained in the credit agreement

• | A default by one of the major financial institutions for which our deposits exceed insured deposit limits

• | Cash on hand outside of the United States that cannot be repatriated without incremental taxation.

Cash Flow for the Six Months Ended December 31, 2017
Cash Flows Provided by Operating Activities
Cash provided by operating activities for the six months ended December 31, 2017 totaled $29.6 million. The various components are as follows:
Net Cash Provided by Operating Activities
(In thousands)

Net income | $ | 8,356 |
Non-cash expenses | 15,168 |
Deferred income tax | 1,657 |
Cash effect of changes in working capital | 4,205 |
Other | 194 |
Net cash provided by operating activities | $ | 29,580 |

Working capital changes at December 31, 2017 in comparison to June 30, 2017 include the following:

• | Accounts receivable, net of bad debt expense recognized during the period and the settlement of $2.0 million of accounts receivable in exchange for backlog (see Item 1. Financial Statements, Note 4 - Intangible Assets Including Goodwill), decreased by $25.5 million during the six months ended December 31, 2017, which increased cash flows from operating activities. The variance is attributable to the timing of billing and collections.

• | Accounts payable decreased by $34.0 million during the six months ended December 31, 2017, which reduced cash flows from operating activities. The variance is primarily attributable to the timing of vendor payments.

• | Costs and estimated earnings in excess of billings on uncompleted contracts ("CIE") decreased $27.0 million, which increased cash flows from operating activities. Billings on uncompleted contracts in excess of costs and estimated earnings ("BIE") decreased $8.8 million, which reduced cash flows from operating activities. The net change in CIE and BIE increased cash $18.2 million for the six months ended December 31, 2017. CIE and BIE balances can experience significant fluctuations based on the timing of when job costs are incurred and the invoicing of those job costs to the customer.

Cash Flows Used for Investing Activities
Investing activities used $5.3 million of cash in the six months ended December 31, 2017 primarily due to $4.1 million of capital expenditures and a $1.7 million working capital payment in connection with the Houston Interests acquisition. Capital expenditures consisted of: $1.8 million for software and office equipment, $0.9 million for transportation and fabrication equipment, $0.8 million for construction equipment, and $0.6 million for buildings. Proceeds from asset sales provided $0.4 million of cash.
Cash Flows Provided by Financing Activities
Financing activities provided $5.4 million of cash in the six months ended December 31, 2017 primarily due to net borrowings of $6.2 million under our credit facility partially offset by the repurchase of $0.6 million of Company stock for payment of withholding taxes due on equity-based compensation, and the payment of $0.4 million for debt amendment fees.
Senior Secured Revolving Credit Facility
As noted previously in Note 5 of the Notes to Condensed Consolidated Financial Statements included in Part 1, Item 1 of this Quarterly Report on Form 10-Q, on February 8, 2017, the Company entered into the Fourth Amended and Restated Credit Agreement (the "Credit Agreement"), by and among the Company and certain foreign subsidiaries, as Borrowers, various subsidiaries of the Company, as Guarantors, JPMorgan Chase Bank, N.A., as Administrative Agent, Sole Lead Arranger and Sole Bookrunner, and the other Lenders party thereto.
The Credit Agreement provides for a five-year senior secured revolving credit facility of $300.0 million that expires February 8, 2022. The credit facility may be used for working capital, acquisitions, capital expenditures, issuances of letters of credit and other lawful purposes.
Except as described in the paragraph below for the August 31, 2017 amendment, the Credit Agreement includes the following covenants and borrowing limitations:

• | Our Leverage Ratio, determined as of the end of each fiscal quarter, may not exceed 3.00 to 1.00.

• | We are required to maintain a Fixed Charge Coverage Ratio, determined as of the end of each fiscal quarter, greater than or equal to 1.25 to 1.00.

• | Asset dispositions (other than dispositions in which all of the net cash proceeds therefrom are reinvested into the Company and dispositions of inventory and obsolete or unneeded equipment in the ordinary course of business) are limited to $20.0 million per 12-month period.

The credit facility includes a sub-facility for revolving loans denominated in Australian Dollars, Canadian Dollars, Euros and Pounds Sterling in an aggregate amount not to exceed the U.S. Dollar equivalent of $75.0 million and a $200.0 million sublimit for letters of credit.
Each revolving borrowing under the Credit Agreement will bear interest at a rate per annum equal to:

• | The ABR or the Adjusted LIBO Rate, in the case of revolving loans denominated in U.S. Dollars;

• | The Canadian Prime Rate or the CDOR rate, in the case of revolving loans denominated in Canadian Dollars;

• | The Adjusted LIBO Rate, in the case of revolving loans denominated in Pounds Sterling or Australian Dollars; or

• | The EURIBO Rate, in the case of revolving loans denominated in Euros,

in each case, plus the Applicable Margin, which is based on the Company's Leverage Ratio. The Applicable Margin on ABR loans ranges between 0.625% and 1.625%. The Applicable Margin for Adjusted LIBO, EURIBO and CDOR loans ranges between 1.625% and 2.625% and the Applicable Margin for Canadian Prime Rate loans ranges between 2.125% and 3.125%.
The unused credit facility fee is between 0.25% and 0.45% based on the Leverage Ratio.
The Credit Agreement includes a Leverage Ratio covenant, which provides that Consolidated Funded Indebtedness, as of the end of any fiscal quarter, may not exceed 3.0 times Consolidated EBITDA, as defined in the Credit Agreement, over the previous four quarters. For the four quarters ended December 31, 2017, Consolidated EBITDA was $25.9 million. Consolidated Funded Indebtedness at December 31, 2017 was $77.9 million.
- 30-

Table of Contents
Consolidated EBITDA, as defined in the Credit Agreement, differs from EBITDA, as reported under "Results of Operations - Non-GAAP Financial Measure," in Item 7 primarily because it permits the Company to:

• | exclude non-cash stock-based compensation expense,

• | include pro forma EBITDA of acquired businesses as if the acquisition occurred at the beginning of the previous four quarters, and

• | exclude certain other extraordinary items, as defined in the Credit Agreement. The Company excluded as extraordinary items the acquisition and integration costs incurred during the previous four quarters.

On August 31, 2017, the Company entered in to an amendment to its Credit Agreement, which provided the following:

• | The maximum permitted Leverage Ratio was temporarily increased to 4.00 to 1.00 for the quarters ending September 30, 2017, and December 31, 2017. The maximum Leverage Ratio will revert back to 3.00 to 1.00 beginning with the quarter ending March 31, 2018.

• | The Fixed Charge Coverage Ratio will not be tested for the quarters ending September 30, 2017 and December 31, 2017, but will be in effect and tested quarterly thereafter beginning with the quarter ending March 31, 2018.

• | A new minimum Consolidated EBITDA covenant was added solely for the four-quarter period ending December 31, 2017. For this period, the Company is required to achieve Consolidated EBITDA of $15.0 million.

• | The Restricted Payments covenant was amended to restrict cash dividends and share repurchases during the period beginning August 31, 2017 and ending December 31, 2017 to an aggregate basket of $5.0 million. In addition, during such period, both cash dividends and share repurchases are prohibited unless the pro forma Leverage Ratio is less than or equal to 2.50 to 1.00. Thereafter, the restriction reverts back to limiting cash dividends to 50% of net income for each fiscal year, and limiting share repurchases to $30.0 million per calendar year.

• | An additional increased pricing tier was added for the "Covenant Relief Period" beginning on August 31, 2017 and ending on the date we deliver our financial statements and compliance certificate for the fiscal quarter ending December 31, 2017. If our Leverage Ratio as of any quarterly calculation date during the Covenant Relief Period exceeds 3.00 to 1.00: (1) the Applicable Margin on ABR loans will be 1.875%; (2) the Applicable Margin for Adjusted LIBO, EURIBO and CDOR will be 2.875%; (3) the Applicable Margin for Canadian Prime Rate loans will be 3.375%; and (4) the unused credit facility fee will be 0.50%.

Availability under the senior secured revolving credit facility at December 31, 2017 was as follows:

| December 31, 2017 |  | June 30, 2017
| (In thousands)
Senior secured revolving credit facility | $ | 300,000 |  |  | $ | 300,000 |
Capacity constraint due to the Senior Leverage Ratio | 196,484 |  |  | 169,092 |
Capacity under the credit facility | 103,516 |  |  | 130,908 |
Borrowings outstanding | 50,908 |  |  | 44,682 |
Letters of credit | 27,026 |  |  | 7,825 |
Availability under the senior secured revolving credit facility | $ | 25,582 |  |  | $ | 78,401 |

Outstanding borrowings at December 31, 2017 under our Credit Agreement were primarily used to fund the acquisition of Houston Interests (See Part 1, Item 1, Note 2 - Acquisitions) and working capital needs in our Canadian business due to the timing of collections and disbursements on a major project in the Electrical Infrastructure segment.
At December 31, 2017, the Company was in compliance with all affirmative, negative, and financial covenants under the Credit Agreement.

Dividend Policy
We have never paid cash dividends on our common stock, and the terms of our Credit Agreement limit the amount of cash dividends we can pay. Under our Credit Agreement, we may declare and pay cash dividends on our capital stock during any fiscal year up to an amount which, when added to all other cash dividends paid during such fiscal year, does not exceed 50% of our cumulative net income for such fiscal year to date, except that, pursuant to an amendment to our Credit Agreement, from August 31, 2017 through December 31, 2017, the total of cash dividend payments, along with share repurchases, may not exceed $5.0 million. In addition, during this time we are prohibited from paying cash dividends or repurchasing stock unless the pro forma Leverage Ratio, as defined in the Credit Agreement, is less than or equal to 2.50 to 1.00. While we currently do not intend to pay cash dividends, any future dividend payments will depend on our financial condition, capital requirements and earnings as well as other relevant factors.
Stock Repurchase Program and Treasury Shares
Treasury Shares
On December 12, 2016, the Board of Directors approved a new stock buyback program (the "December 2016 Program"), which replaced the previous program that had been in place since November 2014. Under the December 2016 Program, the Company may repurchase common stock of the Company in any calendar year commencing with calendar year 2016 and continuing through calendar year 2018, up to a maximum of $25.0 million per calendar year.
The Company may repurchase its stock from time to time in the open market at prevailing market prices or in privately negotiated transactions, except during the period from August 31, 2017 until December 31, 2017, when share repurchases, along with cash dividend payments, are restricted to an aggregate basket of $5.0 million under our Credit Agreement. In addition, during this time share repurchases may only be made if the pro forma Leverage Ratio is less than or equal to 2.50 to 1.00. The December 2016 Program will continue through December 31, 2018 unless and until it is modified or revoked by the Board of Directors. No shares have been repurchased under the December 2016 Program as of December 31, 2017.
The Company has 1,076,541 treasury shares as of December 31, 2017 and intends to utilize these treasury shares in connection with equity awards under the Company’s stock incentive plans and for sales to the Employee Stock Purchase Plan.
FORWARD-LOOKING STATEMENTS
This Form 10-Q includes “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements, other than statements of historical facts, included in this Form 10-Q which address activities, events or developments which we expect, believe or anticipate will or may occur in the future are forward-looking statements. The words “believes,” “intends,” “expects,” “anticipates,” “projects,” “estimates,” “predicts” and similar expressions are also intended to identify forward-looking statements.
These forward-looking statements include, among others, such things as:

• | our ability to generate sufficient cash from operations, access our credit facility, or raise cash in order to meet our short and long-term capital requirements;

• | the impact to our business of crude oil, natural gas and other commodity prices;

• | amounts and nature of future revenues and margins from each of our segments;

• | trends in the industries we serve;

• | the likely impact of new or existing regulations or market forces on the demand for our services;

• | expansion and other trends of the industries we serve;

• | our expectations with respect to the likelihood of a future impairment; and

• | our ability to comply with the covenants in our credit agreement.

- 32-

Table of Contents
These statements are based on certain assumptions and analyses we made in light of our experience and our historical trends, current conditions and expected future developments as well as other factors we believe are appropriate. However, whether actual results and developments will conform to our expectations and predictions is subject to a number of risks and uncertainties which could cause actual results to differ materially from our expectations, including:

• | the risk factors discussed in our Form 10-K for the fiscal year ended June 30, 2017 and listed from time to time in our filings with the Securities and Exchange Commission;

• | economic, market or business conditions in general and in the oil, gas, power, iron and steel, agricultural and mining industries in particular;

• | reduced creditworthiness of our customer base and the higher risk of non-payment of receivables due to low prevailing crude oil and other commodity prices;

• | the inherently uncertain outcome of current and future litigation;

• | the adequacy of our reserves for contingencies;

• | changes in laws or regulations; and

• | other factors, many of which are beyond our control.

Consequently, all of the forward-looking statements made in this Form 10-Q are qualified by these cautionary statements and there can be no assurance that the actual results or developments anticipated by us will be realized or, even if substantially realized, that they will have the expected consequences or effects on our business operations. We assume no obligation to update publicly, except as required by law, any such forward-looking statements, whether as a result of new information, future events or otherwise.
Item 3. Quantitative and Qualitative Disclosures about Market Risk
There have been no material changes in market risk faced by us from those reported in our Annual Report on Form 10-K for the fiscal year ended June 30, 2017, filed with the Securities and Exchange Commission. For more information on market risk, see Part II, Item 7A in our fiscal 2017 Annual Report on Form 10-K.
Item 4. Controls and Procedures
We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Securities Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure based on the definition of “disclosure controls and procedures” in Rule 13a-15(e).
The disclosure controls and procedures are designed to provide reasonable, not absolute, assurance of achieving the desired control objectives. The Company’s management, including the Chief Executive Officer and Chief Financial Officer, does not expect that the disclosure controls and procedures or our internal controls over financial reporting will prevent or detect all errors or fraud. The design of our internal control system takes into account the fact that there are resource constraints and the benefits of controls must be weighed against the costs. Additionally, controls can be circumvented by the acts of key individuals, collusion or management override.
We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of December 31, 2017. Based on the foregoing, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level at December 31, 2017.
We completed the acquisition of Houston Interests, LLC ("Houston Interests") effective December 12, 2016. We are in the process of assessing and, to the extent necessary, making changes to the internal control over financial reporting of Houston Interests to conform such internal control to that used on our other operations. However, we are not yet required to evaluate, and have not yet fully evaluated, changes in Houston Interest's internal control over financial reporting. Subject to the foregoing, there have been no changes in our internal controls over financial reporting that have materially affected, or are reasonably likely to materially affect our internal controls over financial reporting during the quarter ended December 31, 2017.

Dividend Policy
We have never paid cash dividends on our common stock, and the terms of our Credit Agreement limit the amount of cash dividends we can pay. Under our Credit Agreement, we may declare and pay cash dividends on our capital stock during any fiscal year up to an amount which, when added to all other cash dividends paid during such fiscal year, does not exceed 50% of our cumulative net income for such fiscal year to date, except that, pursuant to an amendment to our Credit Agreement, from August 31, 2017 through December 31, 2017, the total of cash dividend payments, along with share repurchases, may not exceed $5.0 million. In addition, during this time we are prohibited from paying cash dividends or repurchasing stock unless the pro forma Leverage Ratio, as defined in the Credit Agreement, is less than or equal to 2.50 to 1.00. While we currently do not intend to pay cash dividends, any future dividend payments will depend on our financial condition, capital requirements and earnings as well as other relevant factors.
