EXPLANATORY NOTE

In April 2019, our management identified an operational deficiency related to reporting requirements under our Third Amended and Restated Credit Agreement (Credit Agreement). For periods prior to and including December 31, 2018, the definition of “Consolidated Funded Indebtedness” used in our consolidated leverage ratio calculation included “the maximum amount available to be drawn under issued and outstanding letters of credit (including standby and commercial), bankers’ acceptances, bank guarantees, surety bonds and similar instruments” and certain restrictions were in place on the incurrence of such instruments. We identified that in periods beginning at least as early as March 31, 2014, we had incurred and not appropriately included certain surety bonds or other similar instruments in our consolidated leverage ratio calculation. As a result, on May 6, 2019, the Company entered into a Consent and Waiver (Consent) to the Credit AgreementThe registrant filed with the financial institutions party thereto under which we are permitted to exclude certain incurred surety bondsSecurities and other similar instruments from the calculation of Consolidated Funded Indebtedness for the period ended March 31, 2019. In addition, the Consent waived all specified violations for all prior periods.

We continue to work with the financial institutions under our Credit Agreement to ensure that the Credit Agreement does not impede our ordinary-course business operations with respect to surety bonds and other similar instruments.

Assessment of Internal Control Over Financial Reporting

In assessing the severity of this deficiency, management considered several circumstances surrounding the deficiency including (i) the fact that surety bonds do not representExchange Commission an outstanding obligation of the Company, (ii) the fact that these surety bonds do not impact our consolidated balance sheets or the related consolidated statements of comprehensive loss, cash flows, and equity, (iii) the speed and willingness with which the financial institutions waived previous violations and agreed to exclude such surety bonds from our calculation of Consolidated Funded Indebtedness for March 31, 2019, (iv) the high probability that the financial institutions would have waived this violation had it been identified upon first occurrence, (v) the fact that we have never had a claim against a surety bond, and (vi) the very low probability that the financial institutions would have “called” our outstanding debt, or enforced any other rights or remedy under the Credit Agreement.

We acknowledge that we should have disclosed the technical covenant breach when the breach originally occurred and that this omitted disclosure, regardless of circumstances above, could be deemed material. Therefore, our management, including our Chief Executive Officer and Chief Financial Officer, have concluded that, for periods prior to and including December 31, 2018, we had a material weakness in our disclosure controls and procedures.

The material weakness did not result in any misstatement to our consolidated balance sheets or the related consolidated statements of comprehensive loss, cash flows, and equityAnnual Report on Form10-K for the year ended December 31, 2018 or any period prior to this date.

Remediation Efforts

Since identifying this deficiency, we have enhanced our internal controls related to our debt covenant calculations by:

We also believe we have accurately calculated and reported our required debt covenant calculations for the March 31,15, 2019, reporting period and are in compliance with required covenant ratios.

TABLE OF CONTENTS

PART II

Item 7.Management’s Discussion And Analysis Of Financial Condition And Results Of Operations

General

The following discussion should be read together with our consolidated financial statements and the related notes included elsewhere in this Annual Report on Form10-K. This discussion contains forward-looking statements about our business and operations. Our future results may differ materially from those we currently anticipate as a result of the factors we describe under “Risk Factors” and elsewhere in this Annual Report on Form10-K.

Executive Overview

We deliver advanced software, optimized industry solutions, and communications infrastructure that allow our customers to realize the business benefits of digital transformation. With world-class, ultra-secure solutions spanning global IP connectivity, bandwidth-optimized OTT applications, IoT big data enablement, and industry-leading machine learning analytics, RigNet supports the full evolution of digital enablement, empowering businesses to respond faster to high priority issues, mitigate the risk of operational disruption, and maximize their overall financial performance.

Our Operations

We are a global technology company that provides customized data and communications services. Customers use our private networks to manage information flows and execute mission-critical operations primarily in remote areas where conventional telecommunications infrastructure is either unreliable or unavailable. We provide our clients what is often the sole means of communications for their remote operations. On top of and vertically integrated into these networks we provide services ranging from fully-managed voice, data, and video to more advanced services including: cyber security threat detection and prevention; applications to improve crew welfare, safety or workforce productivity; and a real-timeAI-backed data analytics platform to enhance customer decision making and business performance.

MCS and Apps & IoT customers are primarily served under fixed-price contracts, either on a monthly or day rate basis or for equipment sales. Our contracts are generally in the form of Master Service Agreements, or MSAs, with specific services being provided under individual service orders. Offshore contracts generally have a term of up to three years with renewal options. Land-based contracts are generally shorter term or terminable on short notice without a penalty. Service orders are executed under the MSA for individual remote sites or groups of sites, and generally permit early termination on short notice without penalty in the event of force majeure, breach of the MSA or cold stacking of a drilling rig (when a rig is taken out of service and is expected to be idle for a protracted period of time). Systems Integration customers are served primarily under fixed-price, long-term contracts.

Segment information is prepared consistent with the components of the enterprise for which separate financial information is available and regularly evaluated by the chief operating decision-maker for the purpose of allocating resources and assessing performance. Managed Communications was renamed Managed Communications Services (MCS).

Corporate and eliminations primarily represents unallocated executive and support activities, interest expense, income taxes, eliminations, the GX dispute and change in fair value ofearn-out/contingent consideration.

Cost of revenue consists primarily of satellite charges, voice and data termination costs, network operations expenses, internet connectivity fees, equipment purchases for Systems Integration projects and direct service labor. Satellite charges consist of the costs associated with obtaining satellite bandwidth (the measure of capacity) used in the transmission of service to and from contracted satellites. Direct service labor consists of field technicians, our Network Operations Center (NOC) employees, and other employees who directly provide services to customers. Network operations expenses consist primarily of costs associated with the operation of our NOC, which is maintained 24 hours a day, seven days a week. Depreciation and amortization are recognized on all property, plant and equipment either installed at a customer’s site or held at our corporate and regional offices, as well as intangibles arising from acquisitions and internal use software. Selling and marketing expenses consist primarily of salaries and commissions, travel costs and marketing communications. General and administrative expenses consist of expenses associated with our management, finance, contract, support and administrative functions.

Profitability generally increases or decreases at a MCS site as we add or lose customers and value-added services. Assumptions used in developing the rates for a site may not cover cost variances from inherent uncertainties or unforeseen obstacles, including both physical conditions and unexpected problems encountered with third party service providers.

Recent Developments

On February 13, 2019, the Company entered into the first amendment to the third amended and restated credit agreement (Updated Credit Agreement) with four participating financial institutions. The Updated Credit Agreement provides for a $15.0 million term loan facility, a $30.0 million term out facility and an $85.0 million revolving credit facility. The revolving credit facility and term out facility mature on April 6, 2021. The term loan facility matures on December 31, 2020.

In January 2019, we announced the appointment of retired Rear Admiral Jamie Barnett as Senior Vice President of Government Services.

We have committed to upgrade our Gulf of Mexico microwave network. In conjunction with a major U.S. carrier, this upgrade will add 4G LTE services and 5G capabilities to the existing network. Additionally, we purchased an office in Lafayette, Louisiana that will consolidate three separate legacy facilities. The Gulf of Mexico LTE network buildout project and the buildout of the Lafayette, Louisiana office will increase capital expenditures into 2019.

In August 2018, we announced the appointment of Lee M. Ahlstrom as Senior Vice President and Chief Financial Officer.

In July 2018, we paid anearn-out of $8.0 million in connection with the March 2016 acquisition of TECNOR. The $2.1 million change in fair value of theearn-out in the year ended December 31, 2018 is primarily related to the second quarter 2018 negotiations with the sellers of TECNOR on the amount of theearn-out. Additionally, we have agreed to pay the sellers of TECNOR up to $1.0 million in either cash or RigNet stock payable in 2019 for the collection of certain accounts receivable balances. As of December 31, 2018, the fair value for the agreement to collect certain accounts receivable was zero.

On April 18, 2018, we completed the separate acquisitions of Automation Communications Engineering Corp. (Auto-Comm) and Safety Controls, Inc. (SAFCON) for an aggregate purchase price of $6.7 million. Of this aggregate purchase price, we paid $2.6 million in cash and $4.1 million in stock. Auto-Comm provides a broad range of communications services, for both onshore and offshore remote locations, to the oil and gas industry. Auto-Comm brings over 30 years of systems integration experience in engineering and design, installation, testing, and maintenance. SAFCON offers a diverse set of safety, security, and maintenance services to the oil and gas industry. Auto-Comm and SAFCON have developed strong relationships with major energy companies that complement the relationships that we have established over the years. Auto-Comm and SAFCON are based in Louisiana.

On March 23, 2018, we completed the acquisition of Intelie Soluções Em Informática S.A (Intelie), for an estimated aggregate purchase price of $18.1 million. Of this aggregate purchase price, we paid R$10.6 million (BRL) (or approximately $3.2 million) in cash, $7.3 million in stock and expect to pay $7.6 million worth of RigNet stock as contingent considerationearn-out, estimated as of the date of acquisition. The initial estimate of theearn-out payable was preliminary and remains subject to change based on the achievement of certain post-closing performance targets under the acquisition agreement. The maximumearn-out is $17.0 million. Intelie is a real-time, predictive analytics company that combines an operational understanding with a machine learning approach. Intelie facilitates innovation via Intelie Pipes, a distributed query language with a complex event processor to aggregate and normalize real-time data from a myriad of data sources. This technology enables the Intelie LIVE platform to solve data integration, data quality, data governance and monitoring problems. Intelie LIVE is an operational intelligence platform that empowers clients to make timely, data-driven decisions in mission-critical real-time operations, including drilling, and longer-term, data-intensive projects, such as well planning. Intelie Live has broad applicability across many industry verticals. Intelie is based in Brazil.

As of December 31, 2018, we have backlog for our percentage of completion projects, which includes our SI projects and our LTE buildout project, of $45.5 million. Our backlog does not extend past 2020.

Known Trends and Uncertainties

Operating Matters

Uncertainties in the oil and gas industry may continue to impact our profitability. The fundamentals of the oil and gas industry we serve remain challenged into 2019, particularly offshore. Although oil prices and U.S. drilling rig counts increased in 2017 and the first three quarters of 2018 since their 2016 lows, the oil and gas environment continues to be challenged with operators focusing on projects with shorterpay-back periods that generally require less capital investment and lower costs from service providers and drilling contractors. The average price of Brent crude, a key indicator of activity for the oil and gas industry, averaged $71.19 per barrel through the year ending December 31, 2018 compared to an average of $54.12 for the year ending December 31, 2017. Brent crude spot prices increased in the first three quarters of 2018 and peaked at $86.07 on October 4, 2018. From the recent October 4, 2018 high, Brent crude oil prices decreased over 40.0% in the fourth quarter of 2018. In the first quarter of 2019 Brent crude oil prices have recovered to over $60 a barrel. As a result, drilling contractors appear cautiously optimistic about a gradual demand recovery. The offshore drilling contracting environment remains challenged, with major offshore drilling contractors having experienced significant pressure on day rates, which in turn has had a negative impact on the rates we are able to charge customers. Generally, a prolonged lower oil price environment decreases exploration and development drilling investment, utilization of drilling rigs and the activity of the global oil and gas industry that we serve.

As of the dates and for the periods referenced below, we were billing on the following sites listed in the table below:

In addition, uncertainties that could impact our profitability and operating cash flows include service responsiveness to remote locations, communication network complexities, political and economic instability in certain regions, export restrictions, licenses and other trade barriers, the availability and cost of satellite bandwidth, timing of collecting our receivables, and our ability to increase our contracted services through sales and marketing efforts while leveraging the contracted satellite and other communication service costs. These uncertainties may result in the delay of service initiation, which may negatively impact our results of operations.

Sales Tax Audit

We are undergoing a routine sales tax audit from a state where we have operations. The audit can cover up to a four-year period. We are in the early stages of the audit and do not have any estimates of further exposure, if any, for the tax years under review.

Global Xpress (GX) Dispute

Inmarsat plc (Inmarsat), a satellite telecommunications company, filed arbitration with the International Centre for Dispute Resolution tribunal (the panel) in October 2016 concerning a January 2014take-or-pay agreement to purchase up to $65.0 million, under certain conditions, of GX capacity from Inmarsat over several years (GX dispute). Phase I of the arbitration, now concluded, concerned only whether our take or pay obligation ever commenced under the agreement. In December 2018, the panel’s Phase I ruling found that atake-or-pay obligation under a January 2014 contract had commenced and that we owed Inmarsat $50.8 million, subject to any offsets from our counterclaims in Phase II of the arbitration. The Phase I ruling is an interim ruling, and we are not required to pay any amounts to Inmarsat until the panel rules on Phase II counterclaims. We currently expect a Phase II ruling in the second half of 2019.

We have an accrued liability of $50.8 million, based on the Phase I interim award amount. While we believe we have strong counterclaims, which will be heard in Phase II and could reduce the ultimate liability, the amount of the final award is not estimable at this time. No assurance can be given as to the ultimate outcome of the GX dispute, and the ultimate outcome may differ from the accrued amount. Based on the information available at this time, the potential final loss could be based on the Phase I ruling less any offsets from our counterclaims in Phase II of the arbitration offset by any potential counterclaims by Inmarsat, including interest and fees. As such, the range of the ultimate liability is currently not estimable.

During the year ended December 31, 2018, we accrued $50.6 million of expense, net of approximately $0.2 million of prior accruals, in the Corporate segment. We have incurred legal expenses of $2.2 million and $1.6 million in connection with the GX dispute for the years ended December 31, 2018 and 2017, respectively. We may continue to incur significant legal fees, related expenses and management time in the future.

Critical Accounting Policies

Certain of our accounting policies require judgment by management in selecting the appropriate assumptions for calculating financial estimates. By their nature, these judgments are subject to an inherent degree of uncertainty. These judgments are based on our historical experience, terms of existing contracts, observance of trends in the industry, information provided by our customers, and information available from other outside sources, as appropriate. Future results may differ from these judgments under different assumptions or conditions. Our accounting policies that require management to apply significant judgment include:

Revenue Recognition—Revenue from Contracts with Customers

Revenue is recognized to depict the transfer of promised goods or services in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services.

Revenue Recognition—MCS and Apps & IoT

MCS and Apps & IoT customers are primarily served under fixed-price contracts, either on a monthly or day rate basis or for equipment sales and consulting services. Our contracts are generally in the form of Master Service Agreements, or MSAs, with specific services being provided under individual service orders. Offshore contracts generally have a term of up to three years with renewal options. Land-based contracts are generally shorter term or terminable on short notice without a penalty. Service orders are executed under the MSA for individual remote sites or groups of sites, and generally permit early termination on short notice without penalty in the event of force majeure, breach of the MSA or cold stacking of a drilling rig (when a rig is taken out of service and is expected to be idle for a protracted period of time).

Performance Obligations Satisfied Over Time—The delivery of service represents the single performance obligation under MCS and Apps & IoT contracts. Revenue for contracts is generally recognized over time as service is transferred to the customer and we expect to be entitled to the agreed monthly or day rate in exchange for those services.

Performance Obligations Satisfied at a Point in Time—The delivery of equipment represents the single performance obligation under equipment sale contracts. Revenue for equipment sales is generally recognized upon delivery of equipment to customers.

Revenue Recognition—Systems Integration

Revenues related to long-term, fixed-price Systems Integration contracts for customized network solutions are recognized based on the percentage of completion for the contract. At any point, RigNet has numerous contracts in progress, all of which are at various stages of completion. Accounting for revenues and profits on long-term contracts requires estimates of total estimated contract costs and estimates of progress toward completion to determine the extent of revenue and profit recognition.

Performance Obligations Satisfied Over Time—The delivery of a Systems Integration solution represents the single performance obligation under Systems Integration contracts. Progress towards completion on fixed-price contracts is measured based on the ratio of costs incurred to total estimated contract costs (thecost-to-cost method). These estimates may be revised as additional information becomes available or as specific project circumstances change.

We review all material contracts on a monthly basis and revise the estimates as appropriate for developments such as providing services, purchasing third-party materials and equipment at costs differing from those previously estimated, and incurring or expecting to incur schedule issues. Changes in estimated final contract revenues and costs can either increase or decrease the final estimated contract profit or loss. Profits are recorded in the period in which a change in estimate is recognized, based on progress achieved through the period of change. Anticipated losses on contracts are recorded in full in the period in which they become evident. Revenue recognized in excess of amounts billed is classified as a current asset under Costs and estimated earnings in excess of billings on uncompleted contracts (CIEB).

Systems Integration contracts are billed in accordance with the terms of the contract which are typically either based on milestones or specified time intervals. As of December 31, 2018 and 2017, the amount of CIEB related to Systems Integration projects was $7.1 million and $2.4 million, respectively. Under long-term contracts, amounts recorded in CIEB may not be realized or paid, respectively, within aone-year period. As of December 31, 2018 and 2017, none and $0.4 million, respectively, of amounts billed to customers in excess of revenue recognized to date are classified as a current liability, under deferred revenue. All of the billings in excess of costs as of December 31, 2017 were recognized as revenue during the year ended December 31, 2018.

Variable Consideration—Systems Integration—We record revenue on contracts relating to certain probable claims and unapproved change orders by including in revenue an amount less than or equal to the amount of costs incurred to date relating to these probable claims and unapproved change orders, thus recognizing no profit until such time as claims are finalized or change orders are approved. The amount of unapproved change orders and claim revenues is included in our Consolidated Balance Sheets as part of CIEB. No material unapproved change orders or claims revenue was included in CIEB as of December 31, 2018 and 2017. As new facts become known, an adjustment to the estimated recovery is made and reflected in the current period.

Revenue related to long-term, fixed-price Systems Integration contracts for customized network solutions are recognized using thepercentage-of-completion method. At any point, RigNet has numerous contracts in progress, all of which are at various stages of completion. Accounting for revenues and profits on long-term contracts requires estimates of total estimated contract costs and estimates of progress toward completion to determine the extent of revenue and profit recognition. Progress towards completion on fixed price contracts is measured based on the ratio of costs incurred to total estimated contract costs (thecost-to-cost method). These estimates may be revised as additional information becomes available or as specific project circumstances change.

Accounts Receivable

Trade accounts receivable are recognized as customers are billed in accordance with customer contracts. We report an allowance for doubtful accounts for probable credit losses existing in accounts receivable. Management determines the allowance based on a review of currently outstanding receivables and our historical collection experience. Individual receivables and balances which have been outstanding greater than 120 days are reviewed individually. Account balances, when determined to be uncollectible, are charged against the allowance.

Property, Plant and Equipment

Property, plant and equipment consists of (i) telecommunication and computer equipment, (ii) furniture and other office equipment, (iii) leasehold improvements, (iv) building and (v) land. All property, plant and equipment, excluding land, is depreciated and stated at acquisition cost net of accumulated depreciation. Depreciation is provided using the straight-line method over the expected useful lives of the respective assets, which range from one to ten years. We assess the value of property, plant and equipment for impairment when we determine that events and circumstances indicate that the recorded carrying value may not be recoverable. An impairment is determined by comparing estimated future net undiscounted cash flows to the carrying value at the time of the assessment. No impairment to property, plant and equipment was recorded in the years ended December 31, 2018, 2017 or 2016.

Any future downturn in our business could adversely impact the key assumptions in our impairment test. While we believe that there appears to be no indication of current or future impairment, historical operating results may not be indicative of future operating results and events and circumstances may occur causing a triggering event in a period as short as three months.

Intangibles

Intangibles consist of customer relationships,covenants-not-to-compete, brand name, licenses, developed technology and backlog acquired as part of our acquisitions. Intangibles also includeinternal-use software. Intangibles have useful lives ranging from 5.0 to 20.0 years and are amortized on a straight-line basis. We assess the value of intangibles for impairment when we determine that events and circumstances indicate that the recorded carrying value may not be recoverable. An impairment is determined by comparing estimated future net undiscounted cash flows to the carrying value at the time of the assessment.

No impairment to intangibles was recorded in the years ended December 31, 2018 or 2017.

In June 2016, we identified a triggering event for a license in Kazakhstan associated with a decline in cash flow projections, which resulted in a $0.4 million impairment of licenses in the Corporate segment, which was the full amount of intangibles within Kazakhstan.

Any future downturn in our business could adversely impact the key assumptions in our impairment test. While we believe that there appears to be no indication of current or future impairment, historical operating results may not be indicative of future operating results and events and circumstances may occur causing a triggering event in a period as short as three months.

Goodwill

Goodwill resulted from prior acquisitions as the consideration paid for the acquired businesses exceeded the fair value of acquired identifiable net tangible and intangible assets. Goodwill is reviewed for impairment at least annually, as of July 31, with additional evaluations being performed when events or circumstances indicate that the carrying value of these assets may not be recoverable.

The goodwill impairment test is used to identify potential impairment by comparing the fair value of each reporting unit to the book value of the reporting unit, including goodwill. Fair value of the reporting unit is determined using a combination of the reporting unit’s expected present value of future cash flows and a market approach. The present value of future cash flows is estimated using our most recent forecast and our weighted average cost of capital. The market approach uses a market multiple on the reporting unit’s cash generated from operations. Significant estimates for each reporting unit included in our impairment analysis are cash flow forecasts, our weighted average cost of capital, projected income tax rates and market multiples. Changes in these estimates could affect the estimated fair value of our reporting units and result in an impairment of goodwill in a future period. If the fair value of a reporting unit is less than its book value, goodwill of the reporting unit is considered to be impaired. If the book value of the reporting unit’s goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess. Any impairment in the value of goodwill is charged to earnings in the period such impairment is determined.

We recorded no goodwill impairments in the years ending December 31, 2018, 2017 or 2016.

MCS had $22.5 million of goodwill as of December 31, 2018, and fair value exceeded carrying value by 34.7% as of the July 31, 2018 annual impairment test. Apps & IoT had $22.8 million of goodwill as of December 31, 2018, and fair

value exceeded carrying value by 48.1% as of the July 31, 2018 annual impairment test. Systems Integration had $1.4 million of goodwill as of December 31, 2018, and fair value exceeded carrying value by 126.5% as of the July 31, 2018 annual impairment test. Any future downturn in our business could adversely impact the key assumptions in our impairment test. While we believe that there appears to be no indication of current or future impairment, historical operating results may not be indicative of future operating results and events and circumstances may occur causing a triggering event in a period as short as three months.

While we believe that there appears to be no indication of current or future impairment, historical operating results may not be indicative of future operating results and events and circumstances may occur causing a triggering event in a period as short as three months.

Stock-Based Compensation

We recognize expense for stock-based compensation based on the fair value of options, restricted stock, restricted stock units and performance share units on the grant date of the awards. Fair value of options on the grant date is determined using the Black-Scholes model, which requires judgment in estimating the expected term of the option, risk-free interest rate, expected volatility and dividend yield of the option. Fair value of restricted stock, restricted stock units and performance share units on the grant date is equal to the market price of RigNet’s common stock on the date of grant. Our policy is to recognize compensation expense for service-based awards on a straight-line basis over the requisite service period of the entire award. Stock-based compensation expense is based on awards ultimately expected to vest.

Taxes

Current income taxes are determined based on the tax laws and rates in effect in the jurisdictions and countries that we operate in and revenue is earned. Deferred income taxes reflect the tax effect of net operating losses, foreign tax credits and the tax effects of temporary differences between the carrying amount of assets and liabilities for financial statement and income tax purposes, as determined under enacted tax laws and rates. Valuation allowances are established when management determines that it is more likely than not that some portion or the entire deferred tax asset will not be realized. The financial effect of changes in tax laws or rates is accounted for in the period of enactment.

From time to time, we engage in transactions in which the tax consequences may be subject to uncertainty. In the normal course of business, we prepare and file tax returns based on interpretation of tax laws and regulations, which are subject to examination by various taxing authorities. Such examinations may result in future tax and interest assessments by these taxing authorities. We evaluate our tax positions and recognize only tax benefits for financial purposes that, more likely than not, will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits of the position.

We have elected to include income tax related interest and penalties as a component of income tax expense.

On December 22, 2017 the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (The Tax Act), making broad and complex changes to the U.S. tax code.

The SEC staff issued SAB 118, which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act.

We have completed the accounting for the income tax effects of the Tax Act based on current regulations and available information. Any additional guidance issued by the IRS could impact our recorded amounts in future periods.

New Accounting Pronouncements

No standard implemented during 2018 or 2017 had a material effect on our financial position, cash flow or results of operations. See our audited consolidated financial statements and the notes thereto included in this Annual Report on Form10-K for more details regarding our implementation and assessment of new accounting standards.

Results of Operations

The following table sets forth selected financial and operating data for the periods indicated.

The following represents selected financial operating results for our segments:

Years Ended December 31, 2018 and 2017

Revenue.Revenue increased by $34.0 million, or 16.6%, to $238.9 million for the year ended December 31, 2018 from $204.9 million for the year ended December 31, 2017. Revenue increased in all segments. The 2018 acquisitions of Auto-Comm, SAFCON and Intelie contributed revenue of $17.7 million for the year ended December 31, 2018. The Systems Integration segment increased $16.5 million, or 66.1%, primarily due to $13.0 million from the acquisition of Auto-Comm and SAFCON and increased activity against a growing backlog of Systems Integration projects. The Apps & IoT segment increased $10.1 million, or 64.6%, due to our focus on growth of the application layer and IoT space including $2.2 million from the acquisition of Intelie, $1.1 million from the acquisition of Auto-Comm and SAFCON and $4.7 million from owning ESS for the full year ended December 31, 2018 compared to five months in 2017. The MCS segment increased $7.3 million, or 4.5%, due to increased average site count coupled with $1.4 million from the acquisition of Auto-Comm and SAFCON and $2.3 million from owning DTS for the full year ended December 31, 2018 compared to two months in 2017.

Cost of Revenue (excluding depreciation and amortization).Cost of revenue (excluding depreciation and amortization) increased by $15.4 million, or 11.8%, to $146.6 million for the year ended December 31, 2017 from $131.2 million for the year ended December 31, 2018. Cost of revenue (excluding depreciation and amortization) increased in the Systems Integration segment by $9.4 million due to the acquisition of Auto-Comm and SAFCON and increased activity of Systems Integration projects. Cost of revenue (excluding depreciation and amortization) increased in the MCS segment by $3.4 million due to serving an increased site count. Cost of revenue (excluding depreciation and amortization) increased in the Apps & IoT segment by $2.6 million as we invested in our strategy of expanding of the application layer and IoT space including the acquisition of Intelie and ESS.

Depreciation and Amortization.Depreciation and amortization expenses increased by $2.3 million to $33.2 million for the year ended December 31, 2018 from $30.8 million for the year ended December 31, 2017. The increase is primarily attributable to additions to property, plant and equipment and intangibles from acquisitions and capital expenditures.

Selling and Marketing.Selling and marketing expenses increased by $4.5 million to $12.8 million for the year ended December 31, 2018 from $8.3 million for the year ended December 31, 2017. This increase was due to investments made towards our growth strategy including increased sales personnel costs, marketing strategy costs and our sales incentive plan (SIP), which increased with revenue.

Change in fair value ofearn-out/contingent consideration.The $3.5 million of expense and $0.3 million of gain, in the years ended December 31, 2018 and 2017, respectively, for change in fair value ofearn-out/contingent consideration is detailed in Note 8 of the Notes to Consolidated Financial Statements of this Annual Report on Form10-K.

GX dispute.The net $50.6 million of expense for the GX dispute in the year ended December 31, 2018 is detailed in in Note 9 of the Notes to Consolidated Financial Statements and in Item 3, Legal Proceedings of this Annual Report on Form 10-K.

General and Administrative.General and administrative expenses increased by $8.4 million to $53.2 million for the year ended December 31, 2018 from $44.8 million for the year ended December 31, 2017. The increase in general and administrative expenses included $4.3 million from acquired business, $2.4 million from bad debt expense, along with other increases from personnel costs and legal expenses.

Income Tax Expense.Our effective income tax rate was 4.2% and (27.3)% for the years ended December 31, 2018 and 2017, respectively. Our effective tax rate is affected by factors including changes in valuation allowances, fluctuations in income across jurisdictions with varying tax rates, and changes in income tax reserves, including related penalties and interest. See Note 13—“Income Taxes,” to our consolidated financial statements included in this Annual Report on Form10-K for more information regarding the items comprising our effective tax rates.

Years Ended December 31, 2017 and 2016

Revenue.Revenue decreased by $15.7 million, or 7.1%, to $204.9 million for the year ended December 31, 2017 from $220.6 million for the year ended December 31, 2016. This decrease was driven by lower MCS revenues, partially offset by an increase in the Apps & IoT and Systems Integration segments. MCS segment revenue decreased $28.3 million, or 14.7%, which was primarily due to decreasedrevenue-per-site from offshore drilling rigs and decreased average offshore sites served partially offset by $1.9 million from the acquisition of DTS. The decreasedrevenue-per-site from offshore drilling rigs is primarily due to decreased multi-tenancy ratios from operators on offshore drilling rigs. Decreased multi-tenancy ratios from operators reduces the opportunity to serve the operator and earn additional revenue until drilling rigs are subsequently contracted for service. Although we were encouraged by the recent increase in offshore drilling rig site count from 175 as of December 31, 2016 to 182 as of December 31, 2017, the average site count decreased from 203 for the year ended December 31, 2016 to 178 for the year ended December 31, 2017. The decrease of 25 average offshore drilling sites served during the year was primarily due to offshore drilling rigs we previously served being cold-stacked or scrapped, partially offset by new sales wins. Revenue continues to be impacted by previously announced reductions in offshore drilling. Apps & IoT segment revenue increased $9.1 million, or 140.6%, due to our growth strategy which focuses on growth into the application layer and IoT space including the acquisition of ESS, which contributed $3.2 million. Systems Integration segment revenue increased $3.4 million, or 15.9%, due to increased activity of Systems Integration projects.

Cost of Revenue (excluding depreciation and amortization).Cost of revenue (excluding depreciation and amortization) increased by $1.4 million, or 1.1%, to $131.2 million for the year ended December 31, 2017 from $129.8 million for the year ended December 31, 2016. Cost of revenue (excluding depreciation and amortization) decreased in the MCS segment by $10.4 million primarily due to reductions in ongoing expenses partially offset by the acquisition of DTS. Cost of revenue increased in the Systems Integration segment by $3.7 million due to increased activity of Systems Integration projects. Cost of revenue increased in the Apps & IoT segment by $8.0 million as we invested in our strategy of expanding into the application layer andinternet-of-things space including the acquisition of ESS and Cyphre.

Depreciation and Amortization.Depreciation and amortization expenses decreased by $2.7 million to $30.8 million for the year ended December 31, 2017 from $33.6 million for the year ended December 31, 2016. The decrease was primarily attributable to lower levels of capital expenditures in recent years, partially offset by additions to property, plant and equipment and intangibles from acquisitions.

Selling and Marketing.Selling and marketing expenses increased by $1.2 million to $8.3 million for the year ended December 31, 2017 from $7.2 million for the year ended December 31, 2016. This increase was due to investing in our growth strategy including more sales and marketing personnel costs.

Change in fair value ofearn-out/contingent consideration.The $0.3 million and $1.3 million of gain, in the years ended December 31, 2017 and 2016, respectively, for change in fair value ofearn-out/contingent consideration is detailed in Note 8 of the Notes to Consolidated Financial Statements of this Annual Report on Form10-K.

General and Administrative.General and administrative expenses decreased by $8.6 million to $44.8 million for the year ended December 31, 2017 from $53.5 million for the year ended December 31, 2016. General and administrative costs decreased in the MCS and Systems Integration segments due to reductions in ongoing expenses partially offset by the acquisition of DTS. General and administrative costs increased in the Apps & IoT segment due to the acquisition of Cyphre and ESS.

Income Tax Expense.Our effective income tax rate was (27.3)% and (106.5)% for the years ended December 31, 2017 and 2016, respectively. Our effective tax rates are affected by factors including changes in the valuation allowance related to operating in loss jurisdictions for which a benefit cannot be claimed, fluctuations in income across international jurisdictions with varying tax rates, and changes in income tax reserves. See Note 13 — “Income Taxes,” to our consolidated financial statements included in this Annual Report on Form10-K for more information regarding the items comprising our effective tax rates.

Liquidity and Capital Resources

At December 31, 2018, we had working capital, including cash, of $2.2 million.

Over the past three years, annual capital expenditures have ranged from $13.6 million to $30.1 million. Based on our current expectations, we believe our liquidity and capital resources will be sufficient for the conduct of our business and operations for the foreseeable future. We may also use a portion of our available cash to finance growth through the acquisition of, or investment in, businesses, products, services or technologies complementary to our current business, through selective mergers, acquisitions, joint ventureshas not been amended, updated or otherwise or to pay down outstanding debt.

After settlement of intercompany payables and notes at December 31, 2018, there is no available cash in foreign subsidiaries available for repatriation to our domestic parent. No deferred tax liability has been recognized as of December 31, 2018 for those earnings that are not considered permanently reinvested.

During the next twelve months, we expect our principal sources of liquidity to be cash flows from operating activities, cash and cash equivalents, availability under our credit agreement and additional financing activities we may pursue, which may include debt or equity offerings. In forecasting our cash flows we have considered factors including contracted and expected services for customers, and contracted and available satellite bandwidth.

While we believe we have sufficient liquidity and capital resources to meet our current operating requirements, the GX dispute and expansion plans, we may elect to pursue additional expansion opportunities within the next year which could require additional financing, either debt or equity.

Beyond the next twelve months, we expect our principal sources of liquidity to be cash flows provided by operating activities, cash and cash equivalents on hand, availability under our credit agreement and additional financing activities we may pursue, which may include debt or equity offerings.

Currently, the Norwegian kroner, the British pound sterling and the Brazilian real are the foreign currencies that could materially impact our liquidity. We presently do not hedge these risks, but evaluate financial risks on a regular basis and may utilize financial instruments in place in the future if deemed necessary. During the years ended December 31, 2018, 2017 and 2016, 91.6%, 90.7% and 85.4% of our revenue was denominated in U.S. dollars, respectively.

Operating Activities

Net cash provided by operating activities was $7.7 million for the year ended December 31, 2018 compared to $29.2 million for the year ended December 31, 2017. The decrease in cash provided by operating activities during 2018 of $21.6 million was primarily due to the timing of collecting receivables coupled with increased operating loss partially offset by the timing of the payment of accounts payable.

Net cash provided by operating activities was $29.2 million for the year ended December 31, 2017 compared to $39.2 million for the year ended December 31, 2016. The decrease in cash provided by operating activities during 2017 of $9.9 million was primarily due to decreased operating activity partially offset by the timing of the payment of accounts payable.

Our cash provided by operations is subject to many variables including the volatility of the oil and gas industry and the demand for our services. Other factors impacting operating cash flows include the availability and cost of satellite bandwidth, as well as the timing of collecting our receivables. Our future cash flow from operations will depend on our ability to increase our contracted services through our sales and marketing efforts while leveraging our contracted satellite and other communication service costs and the outcome of the GX dispute.

Investing Activities

Net cash used in investing activities was $34.2 million, $50.0 million and $18.3 million in the years ended December 31, 2018, 2017 and 2016, respectively. Of these amounts $30.1 million, $18.3 million, and $13.6 million, respectively, were for capital expenditures, an increase of $11.8 million and $4.6 million for the years ended December 31, 2018 and 2017, respectively, compared to each of the respective prior periods. We expect our 2019 capital expenditures to be focused on success-based growth, the buildout of our LTE network in the Gulf of Mexico and the buildout of our Lafayette, Louisiana office, which will consolidate multiple Louisiana facilities into one facility.

Net cash used in investing activities during the year ended December 31, 2018 included $5.2 million paid net of cash acquired in connection with acquisitions consisting of $1.8 million for Auto-Comm and SAFCON net of cash acquired and $3.2 million for Intelie. Net cash used in investing activities during the year ended December 31, 2017 included $32.2 million paid in connection with acquisitions consisting of $4.9 million for Cyphre, $5.1 million for DTS and $22.2 million for ESS.

Financing Activities

Net cash provided by financing activities was $11.9 million in the year ended December 31, 2018. Net cash used in financing activities was $2.8 million and $15.4 million in the years ended December 31, 2017 and 2016 respectively.

Net cash provided by financing activities for the year ended December 31, 2018 included draws of $23.8 million on our revolving credit facility partially offset by $5.1 million in principal payments on our long-term debt. Additionally, we paid the $8.0 million TECNOR earnout in July 2018, of which $6.4 million is recorded as cash used in financing activities and $1.6 million is recorded as cash used in operating activities. The Company received proceeds from the issuance of common stock upon the exercise of stock options of $1.0 million offset by $1.2 million for stock withheld to cover employee taxes on stock-based compensation.

Cash used in financing activities for the year ended December 31, 2017 included $18.2 million in principal payments on our long-term debt partially offset by draws of $15.0 million on our revolving credit facility. This was partially offset by $0.8 million in proceeds from the issuance of common stock upon the exercise of stock options.

Cash used in financing activities for the year ended December 31, 2016 includes $16.6 million in principal payments on our long-term debt consisting of $8.6 million of principal payments on the Term Loan and $8.0 million on the revolving credit facility. This was partially offset by $1.7 million in proceeds from the issuance of common stock upon the exercise of stock options.

Credit Agreement

We have a $15.0 million term loan facility (Term Loan) and an $85.0 million revolving credit facility (RCF), which includes a $25.0 million sublimit for the issuance of commercial and standby letters of credit and performance bonds issued by the parties under the Credit Agreement.

Both the Term Loan and RCF bears an interest rate of LIBOR plus a margin ranging from 1.75% to 2.75%, based on a consolidated leverage ratio defined in the credit agreement. Interest is payable monthly and principal installments of $1.25 million under the Term Loan are due quarterly, with the balance due November 6, 2020.

The weighted average interest rate for the years ended December 31, 2018 and 2017 was 4.8% and 3.3%, respectively, with an interest rate of 5.3% at December 31, 2018. As of December 31, 2018, the outstanding principal amount of the Term Loan was $10.0 million, excluding the impact of unamortized deferred financing costs. As of December 31, 2018, $67.2 million in draws on the RCF remain outstanding.

The credit agreement contains certain covenants and restrictions, including restricting the payment of cash dividends when under default and maintaining certain financial covenants such as a consolidated leverage ratio, defined in the credit agreement, of less than or equal to 2.75 to 1.00 and a consolidated fixed charge coverage ratio of not less than 1.25 to 1.00. If any default occurs related to these covenants that was not cured or waived, the unpaid principal and any accrued interest can be declared immediately due and payable. The facilities under the credit agreement are secured by substantially all our assets.

In April 2019, we determined that in periods beginning at least as early as March 31, 2014, we had incurred and not appropriately included certain surety bonds or other similar instruments in our consolidated leverage ratio calculation as defined by the credit agreement. As a result, on May 6, 2019, we entered into a Consent and Waiver (Consent) to the credit agreement with the financial institutions party thereto under which we are permitted to exclude certain incurred surety bonds and other similar instruments from the calculation of Consolidated Funded Indebtedness, as defined in the credit agreement, for the period ended March 31, 2019. In addition, the Consent waived all specified violations for all prior periods.

We continue to work with the financial institutions under our Credit Agreement to ensure that the Credit Agreement does not impede our ordinary-course business operations with respect to surety bonds and other similar instruments.

Updated Credit Agreement

On February 13, 2019, we entered into the first amendment to the third amended and restated credit agreement (Updated Credit Agreement) with four participating financial institutions. We refinanced $30.0 million of outstanding draws under the existing $85.0 million RCF with a new $30.0 million term out facility. The Updated Credit Agreement requires a $45.0 million reserve (Specified Reserve) under the RCF that will be released and made available for borrowing for payment of monetary damages from the GX dispute. The Updated Credit Agreement provides for a $15.0 million term

loan facility, a $30.0 million term out facility and an $85.0 million revolving credit facility. The revolving credit facility and term out facility mature on April 6, 2021. The term loan facility matures on December 31, 2020.

As of March 1, 2019, and after giving effect to the First Amendment, the outstanding principal amount of the Term Loan was $10.0 million, the outstanding principal amount of the Term Out Loan was $30.0 million, and the outstanding draws on the RCF were $37.2 million with available amounts under the RCF subject to the Specified Reserve.

Under the Updated Credit Agreement, the term loan facility, the term out facility and the revolving credit facility bear interest at a rate of LIBOR plus a margin ranging from 1.75% to 3.00% based on a consolidated leverage ratio defined in the Updated Credit Agreement. Interest is payable monthly and principal installments of $1.25 million under the term loan facility are due quarterly. Principal installments of $1.5 million are due quarterly under the term out facility beginning June 30, 2019. The revolving credit facility contains asub-limit of up to $25.0 million for commercial andstand-by letters of credit issued by parties under the credit agreement.

Our Updated Credit Agreement contains certain covenants and restrictions, including restricting the payment of cash dividends under default, and maintaining certain financial covenants such as a consolidated fixed charge coverage ratio of not less than 1.25 to 1.00 as of December 31, 2018. Additionally, the Updated Credit Agreement requires a consolidated leverage ratio, as defined in the Updated Credit Agreement, of less than or equal to 2.75 to 1.00 as of December 31, 2018. The consolidated leverage ratio increases to 3.25 to 1.00 for four quarters starting in the quarter that we make a final irrevocable payment of all monetary damages from the GX dispute. The consolidated leverage ratio then decreases to 3.00 to 1.00 for three quarters, and then decreases to 2.75 to 1.00 for all remaining quarters. If any default occurs related to these covenants that is not cured or waived, the unpaid principal and any accrued interest can be declared immediately due and payable. The facilities under the Updated Credit Agreement are secured by substantially all our assets.

Off-Balance Sheet Arrangements

We have not engaged in anyoff-balance sheet arrangements.

Contractual Obligations and Commercial Commitments

At December 31, 2018, we had contractual obligations and commercial commitments as follows:

As of December 31, 2018, we have accrued the GX dispute ($50.8 million). This is subject to change in Phase II of the arbitration; therefore, such amounts are not included in the above contractual obligations table. As of December 31, 2018, our other noncurrent liabilities in the Consolidated Balance Sheet consist primarily of the, deferred tax liabilities ($0.7 million), gross unrecognized tax benefits ($16.1 million) and the related gross interest and penalties. At this time, we are unable to make a reasonably reliable estimate of the timing of payments in individual years in connection with these liabilities; therefore, such amounts are not included in the above contractual obligations table.

On September 14, 2012, NesscoInvsat Limited, a subsidiary of RigNet, secured a performance bond facility. On November 6, 2017, this facility became a part of the third amended and restated credit agreement and falls under the $25.0 million sub-limit of the RCF for commercial and standby letters of credit and performance bonds issued by the parties under the Credit Agreement.

As of December 31, 2018, there were no outstanding standby letters of credit and there were $30.5 million of performance bonds outstanding of which $1.7 million is issued by the parties under the Credit Agreement. We have a performance bond facility with a lender in the amount of $1.5 million for our MCS segment. This facility has a maturity date of June 2021. We maintain restricted cash on a dollar for dollar basis to secure this facility.

Non-GAAP Measures

The following table presents a reconciliation of our net loss to Adjusted EBITDA.

We evaluate Adjusted EBITDA generated from our operations to assess the potential recovery of historical capital expenditures, determine timing and investment levels for growth opportunities, extend commitments of satellite bandwidth cost, invest in new products and services, expand or open new offices and service centers, and assess purchasing synergies.

During the year ended December 31, 2018, Adjusted EBITDA increased by $5.1 million from $29.7 million in 2017 to $34.8 million in 2017.

During the year ended December 31, 2017, Adjusted EBITDA decreased by $7.5 million from $37.2 million in 2016 to $29.7 million in 2017.modified.

Our consolidated financial statements, together with the related notes and report of independent registered public accounting firm, are set forth on the pages indicated in Item 15.

Item 9A.Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer (our principal executive officer) and our Chief Financial Officer (our principal financial officer), evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2018. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the Exchange Act), means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Based on their evaluation of our disclosure controls and procedures as of the end of the period covered by this Annual Report, our Chief Executive Officer and Chief Financial Officer concluded that the disclosure controls and procedures were not effective as of December 31, 2018, due to a material weakness in internal control over financial reporting as discussed below.

Changes in Internal Control over Financial Reporting

Except for the material weakness noted below, there were no changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) of the Exchange Act that occurred during the quarter ended December 31, 2018 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Management included in its assessment of internal control over financial reporting all consolidated entities, but excluded certain acquiree processes related to operations from Auto-Comm and SAFCON acquired by the company on April 18, 2018, and Intelie acquired by the Company on March 23, 2018.

Limitations of the Effectiveness of Internal Control

A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the internal control system are met. Because of the inherent limitations of any internal control system, internal control over financial reporting may not detect or prevent misstatements. Projections of any evaluation of the effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies and procedures may deteriorate.

Management’s Annual Report on Internal Control over Financial Reporting (as revised)

The management report called for by Item 308(a) ofRegulation S-K is provided below.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING (as revised)

The management of RigNet, Inc. and its subsidiaries (the Company) is responsible for establishing and maintaining adequate internal control over financial reporting. The Company’s internal control system was designed to provide reasonable assurance to management and the Board of Directors regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

All internal control systems, no matter how well designed, have inherent limitations. Even those systems determined to be effective can provide only reasonable assurance with respect to financial statement presentation and preparation. Further, because of changes in conditions, the effectiveness of internal control may vary over time.

As of December 31, 2018, our management assessed the effectiveness of our internal control over financial reporting based on the criteria for effective internal control over financial reporting established inInternal Control – Integrated Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Management included in its assessment of internal control over financial reporting all consolidated entities, but excluded certain acquiree processes related to operations from Intelie, Auto-Comm and SAFCON acquired by the Company on March 23, 2018, and April 18, 2018, respectively. Intelie, Auto-Comm and SAFCON represents 43% and 11% of net and total assets, respectively, 7% of revenues and 3% of net loss of the consolidated financial statement amounts as of and for the year ended December 31, 2018. Management determined that the internal controls of Intelie, Auto-Comm and SAFCON would be excluded from the internal control assessment as of December 31, 2018, due to the timing of the closing of the acquisitions in March 2018 and April 2018 and as permitted by the rules and regulations of the Securities and Exchange Commission.

Deloitte & Touche LLP, the independent registered public accounting firm that audited our consolidated financial statements included in this Annual Report on Form 10-K, has issued an attestation report on the effectiveness of internal control over financial reporting as of December 31, 2018 which is included in Item 8. Financial Statements and Supplementary Data.

Description of Material Weakness

In evaluating the effectiveness of our disclosure controls and procedures, management identified an operational deficiency related to reporting requirements under our Third Amended and Restated Credit Agreement (Credit Agreement). For periods prior to and including December 31, 2018, the definition of “Consolidated Funded Indebtedness” used in our consolidated leverage ratio calculation included “the maximum amount available to be drawn under issued and outstanding letters of credit (including standby and commercial), bankers’ acceptances, bank guarantees, surety bonds and similar instruments” and certain restrictions were in place on the incurrance of such instruments. In April 2019, we identified that in periods beginning at least as early as March 31, 2014, we had incurred and not appropriately included certain surety bonds or other similar instruments in our consolidated leverage ratio calculation. As a result, on May 6, 2019, the Company entered into a Consent and Waiver (Consent) to the Credit Agreement with the financial institutions party thereto under which we are permitted to exclude certain incurred surety bonds and other similar instruments from the calculation of Consolidated Funded Indebtedness for the period ended March 31, 2019. In addition, the Consent waived all specified violations for all prior periods.

We continue to work with the financial institutions under our credit agreement to ensure that the credit agreement does not impede our ordinary-course business operations with respect to surety bonds and other similar instruments.

We have concluded that we did not properly design and operate adequate internal control over monitoring compliance with financial covenants stipulated by our Third-Amended and Restated Credit Agreement. As a result, the technical violation in our leverage ratio calculation could have resulted in the outstanding amounts under our credit agreement being accelerated under the terms of the arrangement.Therefore, our management, including our Chief Executive Officer and Chief Financial Officer, have concluded that, for periods prior to and including December 31, 2018, we had a material weakness in our internal controls over financial reporting.

The material weakness did not result in any misstatement to our consolidated balance sheets or the related consolidated statements of comprehensive loss, cash flows, and equity for the year ended December 31, 2018, or any period prior to this date.

REMEDIATION EFFORTS TO ADDRESS THE MATERIAL WEAKNESS

Since identifying this deficiency, we have begun to consider the scope of our remediation efforts, including the enhancement of our internal controls related to our debt covenant calculations by:

We have audited the internal control over financial reporting of RigNet, Inc. and subsidiaries (the “Company”) as of December 31, 2018, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, because of the effect of the material weakness identified below on the achievement of the objectives of the control criteria, the Company has not maintained effective internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2018, of the Company and our report dated March 15, 2019 (May 9, 2019, as to the matter described in Note 6 to the consolidated financial statements), expressed an unqualified opinion on those financial statements.

As described in Management’s Report on Internal Control over Financial Reporting (as revised), management excluded from its assessment the internal control over financial reporting at Intelie Soluções Em Informática S.A (“Intelie”) and Automation Communications Engineering Corp. and Safety Controls, Inc. (collectively known as “AutoComm/SAFCON”), which was acquired on March 23, 2018 and April 18, 2018, respectively, and whose financial statements constitute 40% and 10% of net and total assets, respectively, 7% of revenues, and 3% of net loss of the consolidated financial statement amounts of the Company as of and for the year ended December 31, 2018. Accordingly, our audit did not include the internal control over financial reporting at Intelie or AutoComm/SAFCON.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting (as revised). Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Material Weakness

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis. The following material weakness has been identified and included in management’s assessment:

The Company did not properly design and operate adequate internal control over monitoring compliance with financial covenants stipulated by the Company’s Third Amended and Restated Credit Agreement.

This material weakness was considered in determining the nature, timing, and extent of audit tests applied in our audit of the consolidated financial statements as of and for the year ended December 31, 2018, of the Company, and this report does not affect our report on such financial statements.
