NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

1. Basis of Presentation

The accompanying unaudited consolidated financial statements do not include certain information and footnote disclosures required by United States generally accepted accounting principles, or GAAP. The interim financial statements and notes are presented as permitted by instructions to the Quarterly Report on Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, all adjustments necessary for a fair presentation of the interim financial statements have been included and consist only of normal recurring items. The unaudited quarterly financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Annual Report on Form 10-K of Hornbeck Offshore Services, Inc. (together with its subsidiaries, the “Company”) for the year ended December 31, 2018. The results of operations for the three and nine months ended September 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019.

The consolidated balance sheet at December 31, 2018 has been derived from the audited consolidated financial statements at that date, but does not include all of the information and footnotes required by GAAP for complete financial statements.

2. Going Concern

Since the second half of 2014, the offshore oil service sector has experienced difficult operating conditions due to the reduced price of oil. This low oil price environment caused many of the Company's customers to reduce their budgets for the worldwide exploration or production of oil. This reduced spending has negatively impacted the Company's financial results. As discussed in Note 8, the Company's 2020 senior notes and 2021 senior notes mature in April 2020 and March 2021, respectively. The maturity of the Company’s 2020 senior notes now falls within the twelve-month period following the issuance of these financial statements for which the Company is required to evaluate as part of its assessment of its ability to continue as a going concern. Management of the Company continues to believe it has adequate liquidity to fund its operations up until the maturity of the 2020 senior notes. However, absent the combination of a significant recovery of market conditions such that cash flow from operations were to increase materially from currently projected levels, coupled with the refinancing and/or further management of its funded debt obligations, the Company does not currently expect to have sufficient liquidity to repay the full amount of the 2020 senior notes and the 2021 senior notes as they mature in 2020 and 2021, respectively. Management continues to implement its on-going plan to address its maturities as they become due, including efforts in connection with the refinancing of its 2020 senior notes. The closing of the $100 million senior credit facility in June 2019 was the latest step in that iterative process. Based on continuing discussions with existing and potential lenders, management is cautiously optimistic that it will be able to successfully implement this plan. However, management recognizes that its plan depends on the actions of these third parties, including reaching an agreement with existing senior note holders and/or obtaining new sources of liquidity, and, therefore, the Company is unable at this time to conclude that such plan is reasonably certain of being achieved. Accordingly, given the uncertainty with respect to the Company’s ability to pay its 2020 senior notes in full as they become due, the Company acknowledges that substantial doubt exists regarding its ability to continue as a going concern. There can be no assurance that cash flows from operations will increase materially or that the Company will succeed in reaching agreements with its senior note holders or accessing new capital to pay the 2020 senior notes in full as they become due in April 2020.

The accompanying consolidated financial statements have been prepared assuming the Company will continue as a going concern, which contemplates continuity of operations, realization of assets and the satisfaction of liabilities in the normal course of business for the twelve-month period following the date of these consolidated financial statements. As such, the accompanying consolidated financial statements do not include any adjustments relating to the recoverability and classification of assets and their carrying amounts, or the amount and classification of liabilities that may result should the Company be unable to continue as a going concern.

3. Recent Accounting Pronouncements

Standard	Description	Required Date of Adoption	Effect on the financial statements and other significant matters
Standards that have been adopted
ASU No. 2016-02, "Leases" (Topic 842)	This standard requires lessees to recognize a lease liability and a right-of-use asset for all leases (with the exception of short-term leases) at the commencement date. ASU 2016-02 requires a modified retrospective application. Early adoption is permitted.	January 1, 2019	The Company adopted this ASU effective January 1, 2019. See further discussion below and in footnote 12.
ASU No. 2018-02, "Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income"	This standard allows companies to reclassify items in accumulated other comprehensive income to retained earnings for stranded tax effects resulting from The Tax Cuts and Jobs Act.	January 1, 2019	The Company adopted ASU No. 2018-02 on January 1, 2019. This adoption had no material impact on its consolidated financial statements.
ASU No. 2018-09, "Codification Improvements"	This standard provides clarification, corrects errors in and makes minor improvements to various ASC topics. Many of the amendments in this update have transition guidance with effective dates for annual periods beginning after December 15, 2018, and some amendments do not require transition guidance and are effective upon issuance of this update.	January 1, 2019	The Company adopted ASU No. 2018-09 on January 1, 2019. This adoption had no material impact on its consolidated financial statements.
ASU No. 2018-11, "Leases" (Topic 842): Targeted Improvements	This standard provides for the election of transition methods between the modified retrospective method and the optional transition relief method. The modified retrospective method is applied to all prior reporting periods presented with a cumulative-effect adjustment recorded in the earliest comparative period while the optional transition relief method is applied beginning in the period of adoption with a cumulative-effect adjustment recorded in such period. Also, this standard allows lessors to elect to not separate non-lease components from the associated lease components if certain criteria are met.	January 1, 2019	The Company adopted ASU No. 2018-11 on January 1, 2019. See further discussion below.

Standards that have not been adopted
ASU No. 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments"	This standard requires measurement and recognition of expected credit losses for financial assets held. ASU No. 2016-13 requires modified retrospective application. Early adoption is permitted.	January 1, 2023	The Company believes that the implementation of this new guidance will not have a material impact on its consolidated financial statements.

ASC 842, Leases

Lessee Accounting

In February 2016, the Financial Accounting Standards Board, or FASB, issued ASU 2016-02, Leases, which requires lessees to recognize a right-of-use, or ROU, asset and a lease obligation for all leases. This ASU became effective for the Company for its annual reporting period beginning January 1, 2019, including interim periods within that reporting period. The Company adopted the standard using a modified retrospective approach with the effective date of the standard as the date of initial application.

The Company elected the package of practical expedients permitted under the transition guidance within the standard, which eliminates the reassessment of past leases, classification and initial direct costs. For leases with a term of twelve months or less, the Company has made a policy election in which the ROU asset and lease liability will not be recognized on its balance sheet.

As a result of the Company's adoption of this new standard, it recorded ROU assets of $24.7 million and lease liabilities of $27.7 million. The adoption of the standard did not have an impact on the Company's equity and will not have a material impact on the Company's results of operations and cash flows.

Lessor Accounting

Under ASU 2018-11, a lessor may elect to combine lease and non-lease components provided that the non-lease component(s) otherwise would be accounted for under the new revenue guidance in ASC 606 and both of the following conditions are met:

• The timing and pattern of transfer for the lease component are the same as those for the non-lease components associated with that lease component.

• The lease component, if accounted for separately, would be classified as an operating lease.

When the above conditions are met, the entity will need to assess predominance. If the non-lease components are predominant, the entity accounts for the combined component under ASC 606; otherwise, the entity accounts for the combined component under ASC 842.

After review of its revenue streams, the Company has concluded that the non-lease component of its revenue is predominant, and that both of the criteria above are met. Therefore, the Company has adopted the new transition options and combines lease and non-lease revenues. The Company recognizes revenue based on the non-lease component under ASC 606, as it has concluded that the non-lease component is the predominant component. The adoption of ASU 2018-11 on January 1, 2019 did not change the timing or amounts of revenues recognized by the Company.

4. Revenues from Contracts with Customers

Effective January 1, 2018, the Company adopted ASU 2014-09, Revenue from Contracts with Customers, using the modified retrospective method. The adoption of this standard did not have a material impact on the Company's financial position or results of operations. Accordingly, the Company did not make an adjustment to the opening balance of retained earnings in order to account for the implementation of the new requirements of this standard, and it did not restate prior period information for the effects of the new standard.     

The services that are provided by the Company represent a single performance obligation under our contracts that are satisfied at a point in time or over time. Revenues are earned primarily by (1) chartering the Company's vessels, including the operation of such vessels, (2) providing vessel management services to third party vessel owners, and (3) providing shore-based port facility services, including the rental of land. The services generating these revenue streams are provided to customers based upon contracts that include fixed or determinable prices and do not generally include right of return or other significant post-delivery obligations. The Company's vessel revenues, vessel management revenues and port facility revenues are recognized either at a point in time or over the passage of time when the customer has received or is receiving the benefit from the applicable service. Revenues are recognized when the performance obligations are satisfied in accordance with contractual terms and in an amount that reflects the consideration that the Company expects to be entitled to in exchange for the services rendered or rentals provided. Revenues are recognized net of any taxes collected from customers, which are subsequently remitted to governmental authorities. Invoices are typically billed to our customers on a monthly basis and payment terms on customer invoices typically range 30 to 60 days.

A performance obligation under contracts with the Company's customers to render services is the unit of account under Topic 606. The Company accounts for services rendered separately if they are distinct and the service is separately identifiable from other items provided to a customer and if a customer can benefit from the services rendered provided on its own or with other resources that are readily available to the customer. A contract's transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied.

As of September 30, 2019, the Company has certain remaining performance obligations representing contracted vessel revenues for which work has not been performed and such contracts have an original expected duration of more than one year. As of September 30, 2019, the aggregate amount of the transaction price allocated to remaining performance obligations for such contracts was $5.9 million, of which $1.5 million and $4.4 million are expected to be recognized in 2019 and 2020, respectively. The Company has elected to apply the optional exemption for the disclosure of the remaining performance obligations for any of its revenue streams that are expected to have a duration of one year or less and, therefore, such amounts have not been disclosed.

Disaggregation of Revenues

For the three and nine months endedSeptember 30, 2019 and 2018, the Company recognized revenues as follows (in thousands):

	Three Months Ended September 30,				Nine months ended September 30,
	2019		2018		2019		2018
Vessel revenues	$	43,683	$	49,401	$	136,192	$	132,016

	$	52,830	$	58,468	$	163,711	$	158,486

5. Loss per share

Basic and Diluted loss per common share was calculated by dividing net loss by the weighted average number of common shares outstanding during the period. Weighted average number of common shares outstanding was calculated by using the sum of the shares determined on a daily basis divided by the number of days in the period.

The table below reconciles the Company’s loss per share (in thousands, except for per share data): 

	Three Months Ended    September 30,						Nine Months Ended   September 30,

Diluted loss per common share	$	(1.09	)	$	(0.83	)	$	(2.90	)	$	(2.53	)

(1) Due to a net loss, the Company excluded from the calculation of loss per share the effect of equity awards representing the rights to acquire 4,683 and 3,659 shares of common stock for the three and nine months ended September 30, 2019, respectively and 529 shares and 602 shares of common stock for the three and nine months ended September 30, 2018, respectively.

(2) For the nine months ended September 30, 2019 and 2018 and for the three months ended September 2018, the 2019 convertible senior notes were not dilutive, as the average price of the Company’s stock was less than the effective conversion price of such notes. In September 2019, the Company repaid the remaining balance of the 2019 convertible senior notes in full upon their maturity. See Note 8 for further discussion. It was the Company's stated intention to redeem the principal amount of its 2019 convertible senior notes in cash and the Company used the treasury method for determining potential dilution in the diluted earnings per share computation.

(3) Dilutive unvested restricted stock units are expected to fluctuate from quarter to quarter depending on the Company’s performance compared to a predetermined set of performance criteria. See Note 9 to these financial statements for further information regarding certain of the Company’s restricted stock grants.

Asset Impairment Assessment

In accordance with ASC 360, the Company periodically reviews long-lived asset valuations when events or changes in circumstances indicate that an asset’s carrying value may not be recoverable. If indicators of impairment exist, the Company assesses the recoverability of its long-lived assets by comparing the projected future undiscounted cash flows associated with the related long-lived asset group over their remaining estimated useful lives. If the sum of the estimated undiscounted cash flows are less than the carrying amounts of the asset group, the assets are written down to their estimated fair values based on the expected discounted future cash flows or appraised values attributable to the assets. The future cash flows are subjective and are based on the Company’s current assumptions regarding future dayrates, utilization, operating expense, direct overhead, including G&A expense, and recertification costs that could differ from actual results.

During the second quarter of 2016, the Company determined that it observed indicators of impairment related to its vessels. This resulted from the rapid deterioration of its second quarter 2016 operating results, as well as the uncertainty regarding future market conditions and the related impact on the Company's projected operating results. For the purpose of calculating the undiscounted cash flows, the Company grouped its vessels into two groups, OSVs and MPSVs, and used a probability-weighted undiscounted cash flow projection to test for recoverability. Included in the cash flow projections were assumptions related to the current mix of active and stacked vessels, the timing of stacked vessels returning to active status along with projected dayrates, operating expenses and overhead expenses related to each of the groupings.

While the Company has not observed any new impairment indicators since 2016, it has reviewed and updated, as necessary, the assumptions used in determining its undiscounted cash flow projections for each asset group to reflect current market conditions. After reviewing the results of these projections, which were last updated in 2019, the Company determined that each of its asset groups continue to have sufficient projected undiscounted cash flows to recover the remaining book value of the Company's long-lived assets within such group.

7. Acquisition of Vessels

On May 18, 2018, the Company completed the acquisition of four high-spec Jones Act-qualified OSVs and related equipment from Aries Marine Corporation and certain of its affiliates for $40.9 million in cash, inclusive of $4.0 million related to a non-compete intangible asset that is being amortized over the life of such asset, or two years. Also included in this transaction was the cost of fuel and lube inventory and transactions fees. The acquired vessels were all U.S.-flagged and are comprised of two 300 class OSVs and two 280 class OSVs. Subsequent to the acquisition, these four vessels have been foreign-flagged. The Company determined that substantially all of the fair value of the assets acquired are concentrated in a group of similar identifiable assets and, therefore, has accounted for such transaction as an asset acquisition under ASU 2017-01.

The amount reflected in this table is the monthly amount payable based on the 30-day LIBOR interest rate that was in effect on September 30, 2019. Please see further discussion of the variable interest rate below.

Senior Credit Facility

On June 28, 2019, the Company entered into a $100.0 million senior secured asset-based revolving credit facility, or the senior credit facility. The senior credit facility is guaranteed by certain of the Company's domestic and foreign subsidiaries and contains customary representations and warranties, covenants and events of default. The fully-funded senior credit facility is secured by first-priority liens on receivables, certain restricted and unrestricted cash accounts and related assets. The senior credit facility is comprised of two tranches that will rebalance each month based on the variable receivable-backed borrowing base. The unrestricted receivables-backed tranche will mature in 2022, whereas the restricted cash-backed tranche will mature in 2025. The receivables-backed tranche may be used, subject to the completion of applicable eligibility review procedures, for working capital and general corporate purposes, including the refinancing or repayment of existing debt, subject to, among other things, compliance with certain requirements. The cash-backed tranche may, over time, rebalance to the receivables-backed tranche as eligible receivables increase and may be refinanced over time.

11

HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Borrowings under the senior credit facility accrue interest at a floating-rate LIBOR plus a fixed spread of 5.00% for the life of the facility. The Company may, at its option from time to time, prepay loans under either tranche of the senior credit facility. Fifty percent of such loans available under the senior credit facility is subject to a prepayment premium (i) at 103% of the principal amount repaid if such repayment occurs on or prior to June 28, 2020; (ii) at 102% of the principal amount repaid if such repayment occurs on or prior to June 28, 2021; (iii) at 101% of the principal amount repaid if such repayment occurs on or prior to December 28, 2021 and (iv) at 100% of the principal amount repaid if such repayment occurs after December 28, 2021, with such premiums subject to adjustments downward under certain circumstances. The other fifty percent of such loans may be repaid at any time without prepayment penalty.

On September 30, 2019, the Company's restricted cash balance under the senior credit facility was $56.2 million. The Company classifies cash as restricted when there are legal or contractual restrictions on its withdrawal or usage.

First-Lien Term Loans

On June 15, 2017, the Company entered into the first lien term loan agreement (as amended, amended and restated, supplemented or otherwise modified from time to time, the First Lien Term Loan Agreement), by and among the Company, as Parent Borrower, Hornbeck Offshore Services, LLC, or HOS, as Co-Borrower, certain holders of the Company’s then outstanding notes, or the First-Lien Initial Lenders, and Wilmington Trust, National Association, as Administrative Agent and Collateral Agent for the lenders that initially provided for $300 million of first-lien delayed-draw term loans, or the first-lien term loans. On March 1, 2019, the Company entered into Incremental First Lien Term Loan Joinder Agreements with such parties, including certain existing as well as additional lenders, to borrow an additional $50.0 million of first-lien term loans, or the incremental first-lien term loans, under the First Lien Term Loan Agreement, including approximately $30.1 million in cash of new financing. On March 1, 2019, the Company exchanged approximately $21.0 million in face value of its 2019 convertible senior notes in a privately negotiated debt-for-debt exchange for the remaining approximately $19.9 million of incremental first-lien term loans. In accordance with applicable accounting guidance, this debt-for-debt exchange was accounted for as a debt modification. As a result, the Company recorded a loss on early extinguishment of debt of $1.3 million ($1.1 million or $0.03 per diluted share after-tax) due to deal costs associated with the exchange. The incremental first-lien term loans have the same terms applicable to the first-lien term loans originally issued under the existing First Lien Term Loan Agreement.

The Company can use the amounts under the first-lien term loans for working capital and general corporate purposes, including acquisitions and/or the refinancing of existing debt, subject to, among other things, compliance with certain covenants requiring the Company to maintain access to liquidity (cash and credit availability) of $25.0 million at all times. The minimum liquidity level required for prepayment of the Company’s existing indebtedness and/or certain other restricted payments is $65.0 million.

The first-lien term loans are guaranteed by certain of the Company's domestic and foreign subsidiaries and are collateralized on a first-lien basis by certain deposit and securities accounts, 46 domestic high-spec OSVs and MPSVs and nine foreign high-spec OSVs, including a security interest in two pending MPSV newbuilds, and associated personalty, as well as by second-priority liens on receivables, certain unrestricted cash accounts and related assets that secure the senior credit facility on a first-lien basis.

Borrowings accrue interest, at the Company’s option, at either:

• an adjusted London Interbank Offered Rate (subject to a 1.00% floor) plus (a) 6.00% during the first year of the first-lien term loans, (b) 6.50% during the second year of the first-lien term loans, (c) 7.00% during the third year of the first-lien term loans, (d) 7.25% during the fourth year of the first-lien term loans, and (e) 7.50% thereafter; or

• the greatest of (a) the prime rate announced by The Wall Street Journal, (b) the Federal Funds Effective Rate in effect on such day plus 1/2 of 1%, and (c) the London Interbank Offered Rate plus, 1%, plus, for either (a), (b), or (c), a margin of (i) 5.00% during the first year of the first-lien term loans, (ii) 5.50% during the second year of the first-lien term loans, (iii) 6.00% during the third year of the first-lien term loans, (iv) 6.25% during the fourth year of the first-lien term loans, and (v) 6.50% thereafter.

Second-Lien Term Loans

In February and March 2019, the Company completed two private offers and exchanged an aggregate of $142.6 million in face value of its 2020 senior notes for $121.2 million of second-lien term loans due 2025, or second-lien term loans, of the Company and the Co-Borrower. In accordance with applicable accounting guidance, this debt-for-debt exchange was accounted for as a debt modification. As a result, the Company recorded a loss on early extinguishment of debt of $2.4 million ($1.9 million or $0.05 per diluted share after-tax) primarily related to deal costs associated with the exchange. As contemplated by and provided for under the agreement governing the first-lien term loans, the second-lien term loans were made pursuant to a Second Lien Term Loan Agreement entered into by the Company, the Co-Borrower, the lenders party thereto and the Administrative Agent and Collateral Agent. The second-lien term loans have a maturity date of February 7, 2025 and bear interest at a fixed rate per annum of 9.50%. The second-lien term loans are guaranteed by certain of the Company’s domestic and foreign subsidiaries and are collateralized on a second-lien basis, subject to certain permitted liens, by a second-priority interest in the same collateral securing the Company’s first-lien term loans on a first-lien basis and third priority liens on receivables, certain unrestricted cash accounts and related assets that secure the senior credit facility on a first-lien basis.

Convertible Note Repurchases and Repayment

During the nine months ended September 30, 2019, the Company completed a series of private transactions for the repurchase of $52.9 million in face value of its outstanding 2019 convertible senior notes for an aggregate total of $47.6 million of cash. The Company recorded a gain on early extinguishment of debt of $3.6 million ($2.9 million or $0.08 per diluted share after-tax), which was comprised of a $5.6 million gain on the repurchase, offset in part by the write-off of $2.0 million of original issue discount, deal costs and unamortized financing costs related to the notes repurchased.

On September 3, 2019, the Company repaid the remaining balance of $25.8 million in face value of its 2019 convertible senior notes in full upon their maturity, plus accrued and unpaid interest thereon, in accordance with the terms of the indenture governing such notes. The retirement of this debt was funded with cash on hand.

The agreements governing the first-lien term loans and the second-lien term loans, the senior credit facility and the indentures governing the Company's 2020 senior notes and 2021 senior notes impose certain restrictions on the Company. Such restrictions affect, and in many cases limit or prohibit, among other things, the Company's ability to incur additional indebtedness, make capital expenditures, redeem equity, create liens, sell assets and make dividend or other restricted payments.

The Company estimates the fair value of its 2020 senior notes, 2021 senior notes, the first-lien term loans and the second-lien term loans by primarily using quoted market prices. Given the observability of the inputs to these estimates, the Company has assigned a Level 2 of the three-level valuation hierarchy. The interest rate on the senior credit facility is variable and the Company has concluded that face value approximates fair value of such facility as of September 30, 2019.

Capitalized Interest

During the first quarter of 2018, the Company notified the shipyard that was constructing the remaining two vessels in the Company's fifth OSV newbuild program that it was terminating the construction contracts for such vessels. The Company did not capitalize any of its interest costs during the nine months ended September 30, 2019. Upon recommencement of construction of such vessels, the Company intends to resume capitalization of related interest costs. During the nine months ended September 30, 2018, the Company capitalized approximately $2.3 million of interest costs related to the construction of vessels.

9. Incentive Compensation

Stock-Based Incentive Compensation Plan

On June 20, 2019, the Company received stockholder approval to increase the maximum number of shares available under its long-term compensation plan by 7.0 million. The Company’s stock-based incentive compensation plan now covers a maximum of 11.95 million shares of common stock that allows the Company to grant restricted stock awards, restricted stock unit awards, or collectively restricted stock, stock options, stock appreciation rights and fully-vested common stock to employees and directors. As a result of the approval to increase the number of shares available under this plan, the Company, which has the sole discretion in determining the method of settlement for awards granted under the plan, now has the ability and intent to settle these awards using available shares. Accordingly, the classification of and accounting for 5.1 million outstanding phantom stock units, or PSUs, and 1.6 million stock appreciation rights, or SARs, were modified from cash-settled to stock-settled during the second quarter of 2019. These outstanding awards were granted to Company executives in 2017, 2018 and 2019 and to non-executive employees in 2019. After these settlement modifications were completed, the Company has only 0.2 million awards outstanding that will settle in cash on their respective vesting dates. The remaining vesting provisions of the modified awards were not impacted and, therefore, the Company determined the fair value of the awards on the date of the modification was the same as the date prior to the modification. There was no additional compensation expense recognized at the time of modification. As of September 30, 2019, taking into account the outstanding awards now anticipated to be stock-settled, the Company has 0.7 million shares of common stock available to be granted under such plan.

14

HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Restricted Stock

During the nine months ended September 30, 2019, the Company granted 2.4 million time-based PSUs. The compensation expense related to time-based PSUs is amortized over a vesting period of up to three years and is determined based on the market price of the Company’s stock on the date of grant applied to the total shares that are expected to fully vest. All PSUs that remain cash-settled are re-measured quarterly and classified as a liability, due to the originally intended settlement of these awards in cash. As a result of the stockholder approval to increase the number of shares available under its long-term incentive compensation plan, the Company now has the ability to settle certain previously granted PSUs in shares. As such, the value of these awards was determined on the modification date and such expense will not vary in future periods.

In addition to the PSUs granted in 2019, the Company granted performance-based and time-based restricted stock units and phantom restricted stock units in prior years. The PSUs granted in prior years to non-executive employees were not impacted by the June 2019 modification. During the nine months ended September 30, 2019, the Company issued 292,715 shares of common stock due to vestings of restricted stock units and employee purchases under the Company's Employee Stock Purchase Plan.

Stock Appreciation Rights

During the nine months ended September 30, 2019, the Company granted 1.6 million SARs. The SARs vest and become exercisable in three equal annual installments on each of the 1st, 2nd and 3rd anniversaries of the grant date and have a ten-year life. The SARs represent the right to receive, upon exercise, a number of shares of Company common stock, cash, or a combination thereof, at the election of the Company, equal to the product of the aggregate number of shares of Company common stock with respect to which the SAR is exercised and the excess of the fair market value of a share of Company common stock as of the date of exercise over the grant price of $1.38.

On June 20, 2019, the Company determined that it would settle its outstanding SARs in equity rather than cash and such awards are now accounted for as stock-settled SARs. All of the remaining vesting provisions of the SARs are unchanged. The Company estimated the fair value of each SAR on the modification date using the Black-Scholes option-pricing model. As of the modification date, the fair value for the outstanding SARs was $1.02 per share granted.

The following assumptions were used to value SARs on the modification date:

Expected volatility	89.1	%
Expected life	6.0	years
Risk-free interest rate	1.9	%
Expected dividend yield	—	%

The risk-free interest rate used to value SARs is based on the U.S. Treasury yield curve in effect at the time of grant with maturity dates that coincide with the expected life of the SARs. The Company used the simplified method under GAAP to determine the expected life, since this is the first time the Company issued SARs. The Company's assumption for volatility is based on its historical volatility calculated on the grant date.

10. Commitments and Contingencies

Vessel Construction

During the first quarter of 2018, the Company notified the shipyard that was constructing the remaining two vessels in the Company's fifth OSV newbuild program that it was terminating the construction contracts for such vessels based on the shipyard's statements that it would be more than one year late in the delivery of the vessels, among other reasons. On October 2, 2018, the shipyard filed suit against the Company in the 22nd Judicial District Court for the Parish of St. Tammany in the State of Louisiana, or the Gulf Island Litigation. The shipyard claims that the Company's termination was improper and that the shipyard should be permitted to complete construction of the vessels. Alternatively, the shipyard asserts that if the termination was proper, the Company would owe the shipyard compensation for unpaid work. The Company has responded to the suit and has alleged counter-claims. The Company intends to vigorously defend against the shipyard’s claims and considers them to be without merit. The shipyard has frustrated the Company's ability to complete the vessels at a replacement shipyard by asserting that it has possessory rights over the vessels. The Company disputes these asserted possessory rights and believes that the detention of the vessels, over which the Company has title, is wrongful. On November 5, 2019, the district court denied a preliminary motion for summary judgment to require the shipyard to release its possession of the vessels, which may delay further the ability to complete the vessels at a completion shipyard. Because of the shipyard's detention of the vessels, the timeframe in which the vessels can be completed at a replacement shipyard is also uncertain. The Company received performance bonds from sureties. The sureties have denied the Company's claim under the bonds, but did authorize the Company to select a completion yard and, subject to a reservation of rights, offered to fund the cost to complete the vessels in excess of their contract price of up to the full amount of the performance bond. The Company rejected the sureties' conditional and non-conforming offer.

As of the date of termination of the construction contracts, these two remaining vessels, both of which are domestic 400 class MPSVs, were projected to be delivered in the second and third quarters of 2019, respectively. These projected delivery dates were subsequently amended, for guidance purposes, to be the second and third quarters of 2020. Due to the continued uncertainty of the timing and location of future construction activities, the Company is now updating its forward guidance for the delivery dates related to these vessels to be the second and third quarters of 2021, respectively. However, the timing of the remaining construction draws remains subject to change commensurate with any potential further delays in the delivery dates of such vessels. The cost of this nearly completed 24-vessel newbuild program, before construction period interest, is expected to be approximately $1,335.0 million, of which $22.9 million and $35.8 million are currently expected to be incurred in fiscal 2020 and fiscal 2021, respectively. The foregoing amounts do not reflect any potential additional payments to the shipyard in respect of the aforementioned claim.

Contingencies

In the normal course of its business, the Company becomes involved in various claims and legal proceedings in which monetary damages are sought. It is management's opinion that the Company's liability, if any, under such claims or proceedings would not materially affect the Company's financial position or results of operations. The Company insures against losses relating to its vessels, pollution and third party liabilities, including claims by employees under Section 33 of the Merchant Marine Act of 1920, or the Jones Act. Third party liabilities and pollution claims that relate to vessel operations are covered by the Company’s entry in a mutual protection and indemnity association, or P&I Club, as well as by marine liability policies in excess of the P&I Club’s coverage. The Company provides reserves for any individual claim deductibles for which the Company remains responsible by using an estimation process that considers Company-specific and industry data, as well as management’s experience, assumptions and consultation with outside counsel. As additional information becomes available, the Company will assess the potential liability related to its pending claims and revise its estimates. Although historically revisions to such estimates have not been material, changes in estimates of the potential liability could materially impact the Company’s results of operations, financial position or cash flows.

11. Income Taxes

The effective tax benefit rate for the nine months ended September 30, 2019 and 2018 was 21.9% and 18.9%, respectively. The Company's effective tax rate differs from the federal statutory rate due to the establishment of valuation allowances in 2019 and 2018 for state net operating loss, foreign tax credit carryforwards, and nondeductible interest based upon management's conclusion that it is more likely than not such losses and credits will not be realized by their expiration dates. The Company's income tax benefit rate for the nine months ended September 30, 2019 was higher than the benefit rate from the nine months ended September 30, 2018, because of the reversal of a portion of valuation allowances on state net operating loss carryforwards that the Company now believes will be utilized, due to state law changes in June 2019.

During the nine months ended September 30, 2019, the Company adopted ASU 2018-02 and has elected to reclassify the stranded income tax effects of the Tax Cuts and Jobs Act from accumulated comprehensive income to retained earnings. As a result, a reduction in retained earnings and an increase in accumulated other comprehensive income of $1.9 million was recorded in the nine months ended September 30, 2019.

12. Leases

The Company determines if an agreement is a lease or contains a lease at inception. The lease term may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise the option. ROU assets and the corresponding lease liabilities are recorded at the commencement date based on the present value of lease payments over the expected lease term. The Company uses its incremental borrowing rate, which would be the rate incurred to borrow on a collateralized basis over a similar term in a similar economic environment, to calculate the present value of lease payments.

The Company is obligated under certain operating leases for shore-based facilities, office space and temporary housing. Such leases will often include options to extend the lease and the Company will include option periods that, on commencement date, it is reasonably likely that it will exercise. Some leases may require variable lease payments such as real estate taxes and maintenance expenses. These costs are expensed in the period in which they are incurred. None of the Company's leases contain any residual value guarantees. The Company recorded $3.0 million of expense related to leases in general and administrative and operating expenses during the nine months ended September 30, 2019. The expense recorded for short-term leases was $0.4 million during the nine months ended September 30, 2019.

Item 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read together with our unaudited consolidated financial statements and notes to unaudited consolidated financial statements in this Quarterly Report on Form 10-Q and our audited financial statements and notes thereto included in our Annual Report on Form 10-K as of and for the year ended December 31, 2018. This discussion contains forward-looking statements that reflect our current views with respect to future events and financial performance. Our actual results may differ materially from those anticipated in these forward-looking statements. See “Forward Looking Statements” for additional discussion regarding risks associated with forward-looking statements. In this Quarterly Report on Form 10-Q, “company,” “we,” “us,” “our” or like terms refer to Hornbeck Offshore Services, Inc. and its subsidiaries, except as otherwise indicated. Please refer to Item 5—Other Information for a glossary of terms used throughout this Quarterly Report on Form 10-Q.

In this Quarterly Report on Form 10-Q, we rely on and refer to information regarding our industry from the BOEM, EIA and IHS-Petrodata, Inc. These organizations are not affiliated with us and are not aware of and have not consented to being named in this Quarterly Report on Form 10-Q. We believe this information is reliable. In addition, in many cases we have made statements in this Quarterly Report on Form 10-Q regarding our industry and our position in the industry based on our experience in the industry and our own evaluation of market conditions.

General

During the third quarter of 2019, oil prices remained in a range of $50 to $60 per barrel for WTI and Brent. Crude prices still remain below the average prevailing prices between 2005 and late 2014. The sustained decrease in oil prices since 2014 caused major, international and independent oil companies with deepwater operations to significantly reduce their offshore capital spending budgets for the worldwide exploration or production of oil since 2015. Less spending by our customers combined with a global oversupply of OSVs for current market conditions, including high-spec OSVs in our core markets, have resulted in significant reductions in our dayrates and utilization.

The principal question facing the offshore oilfield-related industry is the duration of the current downturn in offshore activities. Our current view is that market conditions in the Greater GoM Operating Region have begun to rebound, however conditions in the third quarter of 2019 reflected little improvement and have not yet resulted in better utilization or pricing for our active fleet of OSVs. In fact during the third quarter of 2019, utilization and effective dayrates for our OSVs worsened over the sequential and prior year quarters. Oil price improvement appears unlikely in the near-term due to continued slower global demand and sustained over supply. Additionally, global economic uncertainty, driven by events such as a trade-war involving the United States and major trading partners, could negatively impact global economic conditions or oil markets.

Against this backdrop, the primary challenge confronting us has been, and continues to be, the ability to repay our senior notes maturing in 2020 and 2021. The maturity of our 2020 senior notes falls within the twelve-month period following the issuance of our financial statements, which we are required to evaluate as part of our assessment of the Company's ability to continue as a going concern. We continue to believe that we have adequate liquidity to fund our operations through at least March 2020. However, absent the combination of a significant recovery of market conditions such that cash flow from operations were to increase materially from currently projected levels, coupled with the refinancing and/or further management of our funded debt obligations, we do not currently expect to have sufficient liquidity to repay the full amount of the 2020 senior notes and the 2021 senior notes as they mature in 2020 and 2021, respectively. Recently, we have engaged in discussions with advisors to and members of an ad hoc group of holders of our 2020 and 2021 notes. These discussions, while positive, are preliminary and we cannot provide assurance that these discussions will result in an acceptable arrangement. As part of our efforts to negotiate an arrangement with

19

holders of our 2020 and 2021 senior notes, we have established a Special Committee of our Board of Directors.

While third quarter 2019 market conditions remained soft and affected our utilization and pricing for OSVs, we continue to observe leading indicators that signal the potential for improved conditions - including larger offshore capital budget announcements by our customers, a growth in the number of final investment decisions, or FIDs, made public by our customers for offshore projects, recently announced deepwater discoveries, a growing contract backlog announced by several drilling contractors and increased customer inquiries for our services, principally in the Greater GoM Operating Region. During the third quarter of 2019, we did not observe any noticeable change in the anticipated supply of high-spec U.S.-flagged OSVs. In the U.S. GoM, two high-spec OSVs have been delivered into the domestic market so far this year. We expect one additional high-spec OSV to be delivered into domestic service in 2019 and one high-spec OSV to be delivered into domestic service in the first quarter of 2020. We do not anticipate significant growth in the supply of high-spec U.S.-flagged OSVs beyond the currently anticipated level of 179 of such vessels by the first quarter of 2020. We continue to monitor the overhang of the dormant supply of stacked U.S.-flagged high-spec OSVs. There are approximately 75 stacked domestic vessels and all of these vessels will require intermediate or special surveys in order to return to service. We believe that the cost to industry participants to reactivate high-spec OSVs, including survey costs, crewing costs, training costs and unanticipated events, will range between $2 million and $5 million per vessel, on average.

During the third quarter of 2019, there was an average of 26.3 floating rigs working in the Greater GoM Operating Region. We see an additional one to two incremental floaters that will begin working in the Greater GoM Operating Region through the end of 2019. While we do not expect that all of these units will work at the same time or that all units currently working will continue to work; overall we view these developments as favorable for market conditions going forward. We believe that these improved regional demand drivers will create increased opportunities for our fleet of new generation OSVs. Once the current supply and demand fundamentals return to more normal conditions, our results from operations should improve.

Unlike our OSVs, whose utilization is tied principally to drilling activities, demand for our MPSVs is also driven by other offshore activities. These vessels are used for a wide variety of oilfield applications that are not necessarily related to drilling. Because of the need to continuously inspect, repair and maintain offshore infrastructure, our MPSVs have, at times, partially counter-acted weakness in overall drilling activities. However, we have not yet seen a significant pick up in the expansion of offshore infrastructure, such as the installation of new floating and subsea infrastructure and field development that more meaningfully drive MPSV utilization. Consequently, utilization of our MPSVs has been volatile. We expect to continue experiencing seasonal fluctuations, with peak activity occurring in late spring through early fall followed by softer demand during the winter months of each year.

Since October 1, 2014, we stacked OSVs and MPSVs on various dates. As of September 30, 2019, as well as October 30, 2019, we had 35 OSVs and two MPSVs stacked and such stacked vessels represent 50% of our fleetwide vessel headcount, and 37% of our total OSV and MPSV deadweight tonnage. The Company plans to reactivate one 265 class OSV during the fourth quarter of 2019 and one MPSV during the first quarter of 2020. We may consider stacking additional vessels or reactivating vessels as market conditions warrant. By stacking vessels, we have significantly reduced our on-going cash outlays and lowered our risk profile; however, we also have fewer revenue-producing units in service that can contribute to our results and produce cash flows to cover our fixed costs and commitments. While we may choose to stack additional vessels should market conditions warrant, our current expectation is to retain our active fleet in the market to accept contracts at the best available terms even if such contracts are below our breakeven cash cost of operations.

In order to support customer requirements in Mexico, and based on our long-term view that Mexico will continue to invest directly or allow foreign investment in its offshore energy sector, and increasingly in deepwater prospects, we elected to Mexican-flag four HOSMAX 300 class OSVs, two 280 class OSVs, two

20

240 class OSVs and one MPSV since January 1, 2018. At present, our Mexican-flagged fleet is comprised of eight high-spec OSVs, five low-spec OSVs and one MPSV, which is the second largest concentration of vessels we have committed to any single national market. Mexico has undergone significant transformation as a market for offshore energy over the last several years. More recently, Mexico's newly elected president has announced an intention to roll-back some of the energy reforms that have created more opportunities for international oil companies, or IOCs, to operate in Mexico. The current administration appears to favor allowing Pemex, as opposed to IOCs, to unlock Mexico's offshore energy resources. We are monitoring the manner in which these policies develop. We have a long-standing relationship with Pemex as well as with the IOCs that have recently entered Mexico. We expect Mexico to continue to refine energy policies that are appropriate to its national objectives.

In Brazil, we presently own and operate one Brazilian-flagged high-spec OSV. We have flexibility under Brazilian law to import and flag into Brazilian registry an additional vessel of similar DWT. We also own and operate one Vanuatu-flagged MPSV currently working in Brazil as a flotel. Brazil is the single largest deepwater market in the world. Recent measures to expand the role of IOCs in its “pre-salt” prospects are taking hold and we believe Brazilian activity in the offshore energy space will be a significant contributor to the overall recovery in global offshore E&P activities.

Our Vessels

All of our current vessels are qualified under the Jones Act to engage in U.S. coastwise trade, except for 18 foreign-flagged new generation OSVs and two foreign-flagged MPSVs. As of September 30, 2019, our 31 active new generation OSVs, six active MPSVs and four managed OSVs were operating in domestic and international areas as noted in the following table:

Critical Accounting Estimates

This Management’s Discussion and Analysis of Financial Condition and Results of Operations discusses our unaudited consolidated financial statements included in this Quarterly Report on Form 10-Q. In many cases, the accounting treatment of a particular transaction is specifically dictated by GAAP. In other circumstances, we are required to make estimates, judgments and assumptions that we believe are reasonable based on available information. We base our estimates and judgments on historical experience and various other factors that we believe are reasonable based upon the information available. Actual results may differ from these estimates under different assumptions and conditions. We continually assess the carrying value of our vessels as discussed below.

21

Carrying Value of Vessels. We depreciate our OSVs and MPSVs over estimated useful lives of 25 years each. Salvage value for our new generation marine equipment is estimated to be 25% of the originally recorded cost for these asset types. In assigning depreciable lives to these assets, we have considered the effects of both physical deterioration largely caused by wear and tear due to operating use and other economic and regulatory factors that could impact commercial viability. To date, our experience confirms that these policies are reasonable, although there may be events or changes in circumstances in the future that indicate that recovery of the carrying amount of our vessels might not be possible.

We presently review the carrying values of our vessels for impairment using the following asset groups: OSVs and MPSVs. We believe that these two vessel groups are appropriate because our vessels are highly mobile among disparate geographies and are directed centrally from our headquarters. Our OSVs share multiple forms of direct and indirect common costs and are marketed on a portfolio basis as an integrated (multi-vessel) marine solution to our customers primarily supporting drilling and exploration activities in various deepwater and ultra-deepwater markets worldwide to our customers. We manage, market, operate and maintain our vessels in a unified manner because we are performing the same services to the same client group across the same geographic regions - i.e., primarily the transportation of the same fungible types of cargo. We believe that our unified approach to operating the vessels within each group is among the most important factors and strategic advantages that drive our customers to utilize our vessels, irrespective of the type or size of vessel that the customer requires on a given engagement. Therefore, management has concluded that the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities is at the OSV and MPSV groupings.

When analyzing asset groups for impairment, we consider both historical and projected operating cash flows, operating income, and EBITDA based on current operating environment and future conditions that we can reasonably anticipate, such as inflation or prospective wage costs. These projections are based on, but not limited to, job location, current and historical market dayrates included in recent sales proposals, utilization and contract coverage; along with anticipated market drivers, such as drilling rig movements, results of offshore lease sales and discussions with our customers regarding their ongoing drilling plans.

If events or changes in circumstances as set forth above were to indicate that the asset group’s carrying amount may not be recoverable over the vessels' useful lives for such groups, we would then be required to estimate the future undiscounted cash flows expected to result from the use of the asset group and its eventual disposition. If the sum of the expected future undiscounted cash flows was determined to be less than the carrying amount of the vessels, we would be required to reduce the carrying amount to fair value. Examples of events or changes in circumstances that could indicate that the recoverability of the carrying amount of our asset groups should be assessed might include a significant change in regulations such as OPA 90, a significant decrease in the market value of the asset group and current period operating or cash flow losses combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the asset group.

During the second quarter of 2016, we identified indicators of impairment relating to our vessels as a result of operating losses occurring for the first time in the our history due to the rapid decline in market conditions. In accordance with GAAP, we calculated the undiscounted cash flows using a probability weighted forecast for each of our asset groups over their respective remaining useful lives. Included in the cash flow projections were assumptions related to the current mix of active and stacked vessels, the estimated timing of stacked vessels returning to active status along with projected dayrates, operating expenses and overhead expenses related to each of the groupings. We view vessel stackings as a temporary status and a prudent business strategy. Stacking vessels does not imply that we have ceased marketing such vessels or intend to never reactivate such vessels when market conditions improve. In fact, we have unstacked vessels in recent quarters and will continue to do so as warranted. The total of the undiscounted cash flows was greater than the net book values of our asset groups and, therefore, we concluded that we did not have an impairment of

22

our long-lived assets as of June 30, 2016, and in such analysis, noted a significant cushion for each of our asset groups as a result of the long remaining useful lives of our vessels.

While we have not observed any new impairment indicators since the second quarter of 2016, each quarterly period, we assess whether there are any new indicators present and whether there have been any events or developments that would indicate that our most recent undiscounted cash flow analysis warrants being updated to reflect a change in inputs or assumptions. We have reviewed and updated, as necessary, the assumptions used in determining our undiscounted cash flow projections for each asset group to reflect current and projected market conditions, and also prepared and updated our sensitivity analysis relating to such assumptions. After reviewing the result of our most recent undiscounted cash flow projections, which were prepared in mid-2019, we have determined that each of our asset groups continues to have sufficient projected undiscounted cash flows to recover the remaining book value of our long-lived assets within such group. In the development of the undiscounted cash flows, in addition to the previously discussed considerations above and in light of current market conditions, we estimate the length of time it will take for the market to absorb our stacked vessels such that we can return those vessels to active status. Any significant revisions to this estimate would have the greatest impact in the development of the undiscounted cash flows. However, as part of our most recent analysis, we determined that if we extended the downturn (and, thus, the unstacking of vessels) by two years from the most recent estimate, this would reduce our undiscounted cash flows by less than 15%, still providing us with substantial excess undiscounted cash flow coverage of the assets’ net book values given the length of remaining useful lives for the assets. Further, we also perform a look-back analysis each quarter to compare our actual performance to that of our most recently prepared undiscounted cash flow analysis. In each case since June 2016, we have noted that our actual quarterly performance has outperformed the applicable estimated undiscounted cash flow calculations used in completing the latest impairment analysis for such comparable period. See Note 6 of our consolidated financial statements included herein for further discussion. We will continue to closely monitor market conditions and potential impairment indicators as long as this market downturn persists.

Our other significant accounting policies and estimates are discussed in Item 7 - Management's Discussion and Analysis of Financial Condition and Results of Operations and in Note 2 to our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2018.

Results of Operations

The tables below set forth the average dayrates, utilization rates and effective dayrates for our owned new generation OSVs and the average number and size of vessels owned during the periods indicated. These vessels generate a substantial portion of our revenues and operating profit. Excluded from the OSV information below are the results of operations for our MPSVs, our shore-based port facility and vessel management services, including the four non-owned vessels managed for the U.S. Navy. The Company does not provide average or effective dayrates for its MPSVs. MPSV dayrates are impacted by highly variable customer-required cost-of-sales associated with ancillary equipment and services, such as ROVs, accommodation units and cranes, which are typically recovered through higher dayrates charged to the customer. Due to the fact that each of our MPSVs have a workload capacity and significantly higher income generating potential than each of the Company’s new generation OSVs, the utilization and dayrate levels of our MPSVs can have a very large impact on our results of operations. For this reason, our consolidated operating results, on a period-to-period basis, are disproportionately impacted by the level of dayrates and utilization achieved by our six active MPSVs.

(1) We owned 66 new generation OSVs as of September 30, 2019. Excluded from this data are eight MPSVs owned and operated by the Company, four non-owned vessels managed for the U.S. Navy. and two MPSV newbuilds currently under construction.

(2) In response to weak market conditions, we elected to stack certain new generation OSVs on various dates since October 1, 2014. Active new generation OSVs represent vessels that are immediately available for service during each respective period.

(3) Utilization rates are average rates based on a 365-day year. Vessels are considered utilized when they are generating revenues.

(4) Effective utilization rate is based on a denominator comprised only of vessel-days available for service by the active fleet, which excludes the impact of stacked vessel days.

(5) Average new generation OSV dayrates represent average revenue per day, which includes charter hire, crewing services, and net brokerage revenues, based on the number of days during the period that the OSVs generated revenues.

(6) Effective dayrate represents the average dayrate multiplied by the average utilization rate.

Non-GAAP Financial Measures

We disclose and discuss EBITDA as a non-GAAP financial measure in our public releases, including quarterly earnings releases, investor conference calls and other filings with the Securities and Exchange Commission. We define EBITDA as earnings (net income) before interest, income taxes, depreciation and amortization. Our measure of EBITDA may not be comparable to similarly titled measures presented by other companies. Other companies may calculate EBITDA differently than we do, which may limit its usefulness as a comparative measure.

We view EBITDA primarily as a liquidity measure and, as such, we believe that the GAAP financial measure most directly comparable to this measure is cash flows provided by operating activities. Because EBITDA is not a measure of financial performance calculated in accordance with GAAP, it should not be considered in isolation or as a substitute for operating income, net income or loss, cash flows provided by operating, investing and financing activities, or other income or cash flow statement data prepared in accordance with GAAP.

EBITDA is widely used by investors and other users of our financial statements as a supplemental financial measure that, when viewed with our GAAP results and the accompanying reconciliations, we believe EBITDA provides additional information that is useful to gain an understanding of the factors and trends affecting our ability to service debt, pay deferred taxes and fund drydocking charges and other maintenance capital expenditures. We also believe the disclosure of EBITDA helps investors meaningfully evaluate and compare our cash flow generating capacity from quarter to quarter and year to year.

EBITDA is also a financial metric used by management as a supplemental internal measure for planning and forecasting overall expectations and for evaluating actual results against such expectations; to compare to the EBITDA of other companies when evaluating potential acquisitions; and to assess our ability to service existing fixed charges and incur additional indebtedness.

The following table reconciles cash flows used in operating activities to EBITDA for the three and nine months ended September 30, 2019 and 2018, respectively (in thousands):

EBITDA	$	(1,924	)	$	5,179		$	3,231		$	9,215

In addition, we have also historically made certain adjustments, as applicable, to EBITDA for losses on early extinguishment of debt, stock-based compensation expense and interest income, to internally evaluate our performance based on the computation of ratios used in certain financial covenants of our credit agreements with various lenders, whenever applicable. We believe that such ratios can, at times, be material components of financial covenants and, when applicable, failure to comply with such covenants could result in the acceleration of indebtedness or the imposition of restrictions on our financial flexibility.

The following table provides certain detailed adjustments to EBITDA, as we define that term, for the three and nine months ended September 30, 2019 and 2018, respectively (in thousands):

	Three Months Ended    September 30,				Nine Months Ended   September 30,
	2019		2018		2019		2018
Loss on early extinguishment of debt, net	$	—	$	—	$	71	$	—
Stock-based compensation expense	876		4,169		2,535		8,922
Interest income	1,314		531		3,349		1,693

25

Set forth below are the material limitations associated with using EBITDA as a non-GAAP financial measure compared to cash flows provided by operating activities.

• EBITDA does not reflect the future capital expenditure requirements that may be necessary to replace our existing vessels as a result of normal wear and tear,

• EBITDA does not reflect the interest, future principal payments and other financing-related charges necessary to service the debt that we have incurred in acquiring and constructing our vessels,

• EBITDA does not reflect the deferred income taxes that we will eventually have to pay once we are no longer in an overall tax net operating loss carryforward position, as applicable, and

• EBITDA does not reflect changes in our net working capital position.

Management compensates for the above-described limitations in using EBITDA as a non-GAAP financial measure by only using EBITDA to supplement our GAAP results.

Three Months Ended September 30, 2019 Compared to Three Months Ended September 30, 2018

Revenues. Revenues for the three months ended September 30, 2019decreased by $5.6 million, or 9.6%, to $52.8 million compared to the same period in 2018. Our weighted-average active operating fleet for the three months ended September 30, 2019 and 2018 was 37.0 and 33.3 vessels, respectively.

Vessel revenues decreased$5.7 million, or 11.6%, to $43.7 million for the three months ended September 30, 2019 compared to $49.4 million for the same period in 2018. The decrease in vessel revenues was primarily due to soft market conditions for our vessels. Revenues from our MPSV fleet decreased $3.0 million, or 16.3%, for the three months ended September 30, 2019 compared to the prior-year period. For the three months ended September 30, 2019, we had an average of 37.0 vessels stacked compared to 40.7 vessels stacked in the prior-year quarter. Average new generation OSV dayrates were $19,750 for the third quarter of 2019 compared to $19,446 for the same period in 2018. Our new generation OSV utilization was 23.4% for the third quarter of 2019 compared to 26.1% for the same period in 2018. Our new generation OSVs were stacked for an aggregate of 3,220 days during the third quarter of 2019 compared to 3,650 days for the same period in 2018. Excluding stacked vessel days, our new generation OSV effective utilization was 49.9% and 65.4% for the same periods, respectively. Domestic vessel revenues decreased $11.3 million from the year-ago quarter primarily due to soft market conditions for our vessels during the three months ended September 30, 2019. Foreign vessel revenues increased $5.6 million due to an additional MPSV operating in a foreign market during the three months ended September 30, 2019. Foreign vessel revenues for the third quarter of 2019 comprised 42.8% of our total vessel revenues compared to 26.6% for the year-ago period.

Non-vessel revenues increased $0.1 million, or 0.9%, to $9.2 million for the three months ended September 30, 2019 compared to $9.1 million for the same period in 2018. This increase is primarily attributable to higher revenues earned from vessel management services during 2019 compared to the year-ago period.

27

Operating Expenses. Operating expenses were $41.1 million, an increase of $2.9 million, or 7.7%, for the three months ended September 30, 2019 compared to $38.2 million for the same period in 2018. Operating expenses increased primarily due to a higher number of active vessels in our fleet during the three months ended September 30, 2019. Aggregate cash operating expenses are projected to be in the approximate annual range of $161.7 million to $166.7 million for the year ending December 31, 2019. Such cash operating expense estimate is exclusive of any additional repositioning expenses we may incur in connection with the potential relocation of more of our vessels into international markets or back to the GoM and any customer-required cost-of-sales related to future contract fixtures that are typically recovered through higher dayrates.

Depreciation and Amortization. Depreciation and amortization expense of $28.6 million was $1.0 million, or 3.7%, higher for the three months ended September 30, 2019 compared to the same period in 2018. Depreciation was in-line with the prior-year period. The increase in amortization expense of $1.3 million was primarily due to costs associated with the initial special surveys for vessels that were placed in service under the Company's fifth OSV newbuild program and costs associated with the drydocking of two vessels that were acquired in the second quarter of 2018. Depreciation expense is expected to increase from current levels when the two remaining vessels under our current newbuild program are placed in service. We expect amortization expense to increase temporarily whenever market conditions warrant reactivation of currently stacked vessels, which will then require us to drydock such vessels, and thereafter to revert back to historical levels.

General and Administrative Expense. G&A expense of $13.4 million was $1.8 millionlower during the three months ended September 30, 2019 compared to the same period in 2018. The decrease was due to lower long-term incentive compensation expense during the three months ended September 30, 2019. Long-term incentive compensation expense was higher in the prior-year quarter primarily due to a "mark to market" adjustment on cash-settled stock-based awards to reflect the increase in our stock price during such quarter. The majority of these cash-settled stock-based awards were modified to settle in stock during the second quarter of 2019 at a price that was lower than such awards were valued during the three months ended September 30, 2018. This favorable variance was partially offset by higher bad debt reserves.

Operating Loss. Operating loss increased by $7.8 million to $30.2 million during the three months ended September 30, 2019 compared to the same period in 2018 for the reasons discussed above. Operating loss as a percentage of revenues was 57.3% for the three months ended September 30, 2019 compared to 38.3% for the same period in 2018.

Interest Expense. Interest expense of $22.2 millionincreased$5.7 million during the three months ended September 30, 2019 compared to the same period in 2018 due to additional interest expense associated with the issuance of additional first-lien and the second-lien term loans as well as the senior credit facility since the third quarter of 2018.

Interest Income. Interest income was $1.3 million during the three months ended September 30, 2019, which was $0.8 millionhigher than the same period in 2018. Our average cash balance increased to $211.0 million for the three months ended September 30, 2019 compared to $115.9 million for the same period in 2018. The average interest rate earned on our invested cash balances was 2.5% and 1.8% during the three months ended September 30, 2019 and 2018, respectively. The increase in average cash balance was primarily due to cash inflows associated with draws under our initial $300 million first-lien term loans, the $50 million expansion of such term loans and the senior credit facility since September 30, 2018. These inflows were partially offset by the repurchases of our 2019 convertible senior notes for cash during September 2019.

Income Tax Benefit. Our effective tax benefit rate was 19.5% and 18.8% for the three months ended September 30, 2019 and 2018, respectively. Our income tax benefit rate for the third quarter of 2019 was higher than the benefit rate from the third quarter of 2018 due to a reduction of net operating loss carryforward valuation allowances due to state tax law changes enacted during the second quarter of 2019. Our income tax benefit primarily consisted of deferred taxes. Our income tax rate differs from the federal statutory rate primarily due to expected state tax liabilities and items not deductible for federal income tax purposes.

Net Loss. Net loss increased by $10.2 million for a reported net loss of $41.4 million for the three months ended September 30, 2019 compared to a net loss of $31.2 million for the same period during 2018. This

28

unfavorable variance in net loss was primarily driven by higher operating loss and interest expense partially offset by a higher tax benefit rate in the three months ended September 30, 2019.

Nine Months Ended September 30, 2019 Compared to Nine Months Ended September 30, 2018

Revenues. Revenues for the nine months ended September 30, 2019increased by $5.2 million, or 3.3%, to $163.7 million compared to the same period in 2018. Our weighted-average active operating fleet for the nine months ended September 30, 2019 and 2018 was 36.2 and 29.8 vessels, respectively.

Vessel revenues increased$4.2 million, or 3.2%, to $136.2 million for the nine months ended September 30, 2019 compared to $132.0 million for the same period in 2018. The increase in vessel revenues primarily resulted from improved market conditions for our OSVs and the addition of four OSVs to our operating fleet during the second quarter of 2018 partially offset by soft market conditions for our MPSVs. Revenues from our MPSV fleet decreased $11.9 million, or 23.9%, for the nine months ended September 30, 2019 compared to the prior-year period. For the nine months endedSeptember 30, 2019, we had an average of 37.8 vessels stacked compared to an average of 42.2 vessels stacked in the prior-year period. Average new generation OSV dayrates were $18,600 for the first nine months of 2019 compared to $19,097 for the same period in 2018, a decrease of $497, or 2.6%. Our new generation OSV utilization was 29.4% for the first nine months of 2019 compared to 24.7% for the same period in 2018. Our new generation OSVs incurred 408 days of aggregate downtime for regulatory drydockings and were stacked for an aggregate of 9,738 days during the first nine months of 2019. Excluding stacked vessel days, our new generation OSV effective utilization was 63.9% and 70.5% during the nine months ended September 30, 2019 and 2018, respectively. Domestic vessel revenues decreased $26.4 million from the year-ago period primarily due to lower revenue earned by our MPSVs operating domestically during the nine months endedSeptember 30, 2019. Foreign vessel revenues increased $30.6 million. The increase in foreign revenues is attributable to an average of 4.7 additional vessels working in foreign locations during the current-year period. Foreign vessel revenues for the first nine months of 2019 comprised 42.3% of our total vessel revenues compared to 20.5% for the year-ago period.

30

Non-vessel revenues increased$1.0 million, or 4.0%, from the prior-year period. This increase is primarily attributable to higher revenues earned from vessel management services during the nine months ended September 30, 2019 compared to the year-ago period.

Operating Expenses. Operating expenses were $121.7 million, an increase of $12.7 million, or 11.7%, for the nine months ended September 30, 2019 compared to $109.0 million for the same period in 2018. Operating expenses were higher due to an increased number of active vessels in our fleet during the nine months ended September 30, 2019.

Depreciation and Amortization. Depreciation and amortization expense of $85.4 million was $4.3 million, or 5.3%, higher for the nine months ended September 30, 2019 compared to the same period in 2018. Depreciation was in-line with the prior-year period. Amortization expense increased$4.4 million, which was driven higher mainly by costs associated with the initial special surveys for vessels that were placed in service under the Company's fifth OSV newbuild program, costs associated with the drydocking of two vessels that were acquired in the second quarter of 2018 and the amortization of an intangible asset that was included with the acquisition of four OSVs in the second quarter of 2018.

General and Administrative Expense. G&A expense of $38.4 million was $1.9 millionlower during the nine months ended September 30, 2019 compared to the same period in 2018. The decrease in G&A expense was primarily attributable to lower long-term incentive compensation expense and legal fees. Long-term incentive compensation expense was lower primarily due to a "mark to market" adjustment on cash-settled stock-based awards to reflect the increase in our stock price during the nine months ended September 30, 2018. The majority of these cash-settled stock-based awards were modified to settle in stock during the second quarter of 2019 at a price that was lower than such awards were valued during the prior-year period. These favorable variances were partially offset by higher short-term incentive compensation expense and higher bad debt reserves.

Operating Loss. Operating loss increased by $9.9 million to an operating loss of $81.7 million during the nine months ended September 30, 2019 compared to the same period in 2018 for the reasons discussed above. Operating loss as a percentage of revenues was 49.9% for the nine months ended September 30, 2019 compared to 45.3% for the same period in 2018.

Loss on Early Extinguishment of Debt, Net. During the nine months ended September 30, 2019, we exchanged $142.6 million in face value of 2020 senior notes for $121.2 million of second-lien term loans and we exchanged $21.0 million in face value of our 2019 convertible senior notes for $19.9 million of first-lien term loans. In accordance with applicable accounting guidance, these debt-for-debt exchanges were accounted for as debt modifications, requiring the Company to defer the gains on such exchanges and record a loss on early extinguishment of debt of $3.7 million related to deal costs for the exchanges. During the nine months ended September 30, 2019, we arranged for the repurchase of $52.9 million of our outstanding 2019 convertible senior notes for an aggregate total of $47.6 million of cash. We recorded a net gain on early extinguishment of debt of $3.6 million ($2.9 million or $0.08 per diluted share after-tax) related to these repurchases.

Interest Expense. Interest expense of $62.0 million was $15.1 millionhigher than the same period in 2018 due to incremental interest expense associated with the issuance of additional first-lien and the second-lien term loans as well as the senior credit facility since the third quarter of 2018.

Interest Income. Interest income was $3.3 million during the nine months ended September 30, 2019, which was $1.7 millionhigher than the same period in 2018. Our average cash balance increased to $191.9 million for the nine months ended September 30, 2019 compared to $153.7 million for the same period in 2018. The average interest rate earned on our invested cash balances was 2.3% and 1.5% during the nine months ended September 30, 2019 and 2018, respectively. The increase in average cash balance was primarily due to cash inflows associated with draws under our initial $300 million first-lien term loans and the $50 million expansion of such term loans as well as the senior credit facility since September 30, 2018. These inflows were partially offset by the repurchases of our 2019 convertible senior notes for cash during the nine months ended September 30, 2019.

31

Income Tax Benefit. Our effective tax benefit rate was 21.9% and 18.9% for the nine months ended September 30, 2019 and 2018, respectively. Our income tax benefit for the nine months ended September 30, 2019 was higher than the benefit rate from the nine months ended September 30, 2018 due to a reduction of net operating loss carryforward valuation allowances due to state tax law changes enacted during the second quarter of 2019. Our income tax benefit primarily consisted of deferred taxes. Our income tax rate differs from the federal statutory rate primarily due to expected state tax liabilities and items not deductible for federal income tax purposes.

Net Loss. Net loss increased by $15.0 million for a reported net loss of $110.0 million for the nine months ended September 30, 2019 compared to a net loss of $94.9 million for the same period during 2018. This unfavorable variance in net loss was primarily driven by increased operating expenses for our vessels and interest expense, partially offset by increased revenue earned by such OSVs during the nine months ended September 30, 2019.

Liquidity and Capital Resources

As of September 30, 2019, we had total cash and cash equivalents of $136.4 million and restricted cash of $56.5 million. We are currently in compliance with all applicable covenants under our senior credit facility, our term loan agreements and the indentures governing our senior notes.

We have $350 million of first-lien term loans that mature in June 2023 and have $121 million in second-lien term loans that mature in February 2025, which are all guaranteed by our significant domestic subsidiaries other than Hornbeck Offshore Services, LLC, which is the Co-Borrower under the term loan agreements, and certain of our foreign subsidiaries. The term loan agreements contain customary representations and warranties, covenants and events of default, but only one maintenance covenant, which is a $25 million minimum liquidity requirement. On June 28, 2019, we entered into a $100.0 million senior credit facility. The senior credit facility is guaranteed by certain of our domestic and foreign subsidiaries and contains customary representations and warranties, covenants and events of default. See Note 8 of the Notes to Consolidated Financial Statements for further discussion of the first-lien term loans, second-lien term loans and the senior credit facility.

Our capital requirements have historically been financed with cash flows from operations, proceeds from issuances of our debt and common equity securities, borrowings under our revolving and term loan agreements and cash received from the sale of assets. We require capital to fund on-going operations, remaining obligations under our fifth OSV newbuild program, vessel recertifications, discretionary capital expenditures, debt service and debt repayment and may require capital to fund potential future vessel construction, retrofit or conversion projects, acquisitions, stock repurchases or the retirement of debt. The nature of our capital requirements and the types of our financing sources are not expected to change significantly for the balance of 2019.

We regularly review all of our debt agreements, including the agreements governing the senior credit facility, first-lien term loans and second-lien term loans, as well as our liquidity position and projected future cash needs. Despite volatility in commodity prices, we remain confident in the long-term viability of our business model upon improvement in market conditions. Since the fall of 2014, our liquidity has been impacted by low oil and natural gas prices, which together with oil and natural gas being produced in greater volumes onshore, has impacted the extent of offshore exploration and development activities, resulting in lower than normal cash flow from operations. However, we project that, even with the current depressed operating levels, cash generated from operations together with cash on-hand should be sufficient to fund our operations and commitments through at least March 31, 2020. We also believe that we will be able to fund all of the deferred maintenance capital expenditures that will be required upon reactivation of our stacked vessels when market conditions improve with existing sources of liquidity. We have two tranches of funded senior unsecured debt outstanding that mature in fiscal years 2020 and 2021, respectively. However, absent the combination of a significant recovery of market conditions such that cash flow from operations were to increase materially from currently projected levels coupled with the refinancing and/or further management of our funded debt obligations, we do not currently expect to have sufficient liquidity to repay the full amount of our 2020 senior notes and 2021 senior notes as they mature in fiscal years 2020 and 2021, respectively. We continue to

32

implement our on-going plan to address these maturities as they become due, including efforts in connection with the refinancing of our 2020 and 2021 senior notes. The issuance of first-lien term loans and second-lien term loans were significant measures that enabled us to be in a position to repay the remaining balance of our 2019 convertible notes in full at maturity and significantly reduce the amount of face value outstanding of our 2020 senior notes from $367 million to $224 million. Our $100 million senior credit facility entered into in June 2019 was the latest step in that iterative process. Based on continuing discussions with existing and potential lenders, we are optimistic that we will be able to successfully implement this plan. However, we recognize that our plan depends on the actions of these third parties, including reaching an agreement with existing senior note holders and/or obtaining new sources of liquidity, and, therefore, we are unable at this time to conclude that such plan is reasonably certain of being achieved. Moreover, refinancing in the current climate is not likely to be achievable on terms that are in-line with our pre-downturn cost of debt capital. We remain fully cognizant of the challenges currently facing the offshore oil and gas industry and are proactively taking steps to protect the business enterprise.

We may, subject to market conditions and our other strategic options, from time to time amend, extinguish or repurchase part or all of our outstanding debt securities or exchange them for other debt or equity securities or loans. While we have an authorized share repurchase program, we currently intend, subject to market conditions, to prioritize our cash usage appropriate to the current market cycle, our longer term commitments and our strategic objectives.

Events beyond our control, such as sustained low prices for oil and natural gas, a further significant decline in such commodity prices, renewed regulatory-driven delays in the issuance of drilling plans and permits in the Greater GoM Operating Region, declines in expenditures for offshore exploration, development and production activity, any extended reduction in domestic consumption of refined petroleum products and other reasons discussed under the "Forward Looking Statements" on page ii and "Item 1A—Risk Factors" of our Annual Report on Form 10-K, may affect our financial condition, results of operations or cash flows in the future. Should the need for additional financing arise, we may not be able to access the capital markets on attractive terms at that time or otherwise obtain sufficient capital to meet our maturing debt obligations or finance growth opportunities that may arise. We will continue to closely monitor our liquidity position, as well as the state of the global capital and credit markets. See further discussion in the Contractual Obligations section below.

Cash Flows

Operating Activities. Historically, we have relied primarily on cash flows from operations to provide working capital for current and future operations. Cash flows used in operating activities were $72.3 million for the nine months ended September 30, 2019 compared to cash flows used in operating activities of $25.8 million for the same period in 2018. Operating cash flows for the first nine months of 2019 were unfavorably affected by weak market conditions for our vessels operating worldwide and higher cash outflows associated with the regulatory recertifications for our active vessels.

Investing Activities. Net cash used in investing activities was $3.9 million for the nine months ended September 30, 2019 compared to $51.9 million for the same period in 2018. Cash used during the first nine months of 2019 consisted primarily of construction costs paid for our fifth OSV newbuild program, as well as capital improvements to our operating fleet. Cash used during the first nine months of 2018 consisted primarily of the purchase of four high-spec Jones Act-qualified OSVs and related equipment from Aries Marine Corporation.

Financing Activities. Net cash provided by financing activities was $44.3 million for the nine months ended September 30, 2019 compared to $0.3 million of net cash used in financing activities for the same period in 2018. Net cash provided by financing activities for the nine months ended September 30, 2019 resulted from

33

net proceeds from the senior credit facility and the incremental first-lien term loans, partially offset by the repurchase of the remainder of the 2019 convertible senior notes on their due date.

Contractual Obligations

Debt

As of September 30, 2019, the Company had the following outstanding debt (in thousands, except effective interest rate):

	Total Debt		Effective Interest Rate		Cash Interest Payment		Payment Dates

5.000% senior notes due 2021, net of deferred financing costs of $1,446 (1)	448,554		5.21	%	11,250		March 1 and September 1
First-lien term loans due 2023, plus deferred gain of $13,913, net of original issue discount of $3,310 and deferred financing costs of $3,491 (2)	357,112		9.05	%	2,728		Variable
Second-lien term loans due 2025, including deferred gain of $19,460	140,695		9.50	%	2,879		January 31, April 30, July 31, and October 31
Senior credit facility, net of deferred financing costs of $5,969 (3)	94,031		7.10	%	611		Monthly
	$	1,264,218

(1) The senior notes do not require any payments of principal prior to their stated maturity dates, but pursuant to the indentures under which the 2020 and 2021 senior notes were issued, we would be required to make offers to purchase such senior notes upon the occurrence of specified events, such as certain asset sales or a change in control.

(2) The interest rate on the first-lien term loan is variable based on a base rate at the Company's election, plus an applicable margin, which is currently 7.00%. The amount reflected in this table is the monthly amount payable based on the 30-day LIBOR interest rate that was elected and in effect on September 30, 2019. Please see Note 8 for further discussion of the variable interest rate applicable to the first-lien term loans.

(3) The interest rate on the senior credit facility is variable based on 30-day LIBOR plus a fixed margin of 5.00%. The amount reflected in this table is the monthly amount payable based on the 30-day LIBOR interest rate that was in effect on September 30, 2019. Please see Note 8 for further discussion of the variable interest rate applicable to the senior credit facility.

The credit agreements governing our senior credit facility, our first-lien term loans and second-lien term loans and the indentures governing our 2020 and 2021 senior notes impose certain operating and financial restrictions on us. Such restrictions affect, and in many cases limit or prohibit, among other things, our ability to incur additional indebtedness, make capital expenditures, redeem equity, create liens, sell assets and pay dividends or make other restricted payments. For the nine months ended September 30, 2019, we were in compliance with all applicable financial covenants. We continuously review our debt covenants and report to the agents for the lenders of our first-lien term loans and second-lien term loans our compliance with all applicable covenants on a quarterly basis and we report to the agent of our senior credit facility our compliance with the applicable covenants on a monthly basis. We also consider such covenants in evaluating transactions that will have an effect on our financial ratios.

During the first quarter of 2018, the Company notified the shipyard that was constructing the remaining two vessels in the Company's fifth OSV newbuild program that it was terminating the construction contracts for such vessels. See additional discussion in Note 10 of our consolidated financial statements included herein for further discussion and in Legal Proceedings.

The cost of this nearly completed 24-vessel newbuild program, before construction period interest, is expected to be approximately $1,335.0 million, of which $22.9 million and $35.8 million are currently expected to be incurred in fiscal 2020 and fiscal 2021, respectively. As of the date of termination, these two remaining vessels, both of which are domestic 400 class MPSVs, were projected to be delivered in the second and third quarters of 2019, respectively. These projected delivery dates were subsequently amended, for guidance purposes, to be the second and third quarters of 2020. Due to the continued uncertainty of the timing and location of future construction activities, the Company is now updating its forward guidance for the delivery dates related to these vessels to be the second and third quarters of 2021, respectively. The Company has not revised its estimate of the cost to complete the vessels to reflect the disputed claims asserted by the shipyard.

34

In addition, the Company has not included any potential costs to complete the vessels in excess of the original contract price that may not be covered by surety bonds due to the sureties' denial of claims or for any other reasons. The timing of remaining construction draws remains subject to change commensurate with any potential further delays in the delivery dates of such vessels. From the inception of this program through September 30, 2019, the Company had incurred $1,276.3 million, or 95.6%, of total expected project costs. During the nine months ended September 30, 2019, the Company incurred $2.2 million related to the construction of these vessels.

Maintenance and Other Capital Expenditures

The following table summarizes the costs incurred, prior to the allocation of construction period interest, for the purposes set forth below for the three and nine months ended September 30, 2019 and 2018, respectively, and a forecast for the fiscal year ending December 31, 2019 (in millions):

Forward Looking Statements

This Quarterly Report on Form 10-Q contains “forward-looking statements,” as contemplated by the Private Securities Litigation Reform Act of 1995, in which the Company discusses factors it believes may affect its performance in the future. Forward-looking statements are all statements other than historical facts, such as statements regarding assumptions, expectations, beliefs and projections about future events or conditions. You can generally identify forward-looking statements by the appearance in such a statement of words like “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “forecast,” “intend,” “may,” “might,” “plan,” “potential,” “predict,” “project,” “remain,” “should,” “will,” or other comparable words or the negative of such words. The accuracy of the Company’s assumptions, expectations, beliefs and projections depends on events or conditions that change over time and are thus susceptible to change based on actual experience, new developments and known and unknown risks. The Company gives no assurance that the forward-looking statements will prove to be correct and does not undertake any duty to update them. The Company’s actual future results might differ from the forward-looking statements made in this Quarterly Report on Form 10-Q for a variety of reasons, including impacts from changes in oil and natural gas prices in the U.S. and worldwide; continued weakness in demand and/or pricing for the Company’s services through and beyond the maturity of any of the Company's long-term debt; unplanned customer suspensions, cancellations, rate reductions or non-renewals of vessel charters, or vessel management contracts, or failures to finalize commitments to charter or manage vessels; continued weakness in capital spending by customers on offshore exploration and development; the inability to accurately predict vessel utilization levels and dayrates; sustained weakness in the number of deepwater and ultra-deepwater drilling units operating in the GoM or other regions where the Company operates; the Company’s inability to successfully complete the final two vessels of its current vessel newbuild program on-budget, including any failure or refusal by the issuer of performance bonds to honor the bond contract or to cover cost overruns that may result at a completion shipyard; the inability to successfully market the vessels that the Company owns, is constructing or might acquire; the U.S. government's cancellation or non-renewal of the management, operations and maintenance contracts for non-owned vessels; an oil spill or other significant event in the United States or another offshore drilling region that could have a broad impact on deepwater and other offshore energy exploration and production activities, such as the suspension of activities or significant regulatory responses; the imposition of laws or regulations that result in reduced exploration and production activities or that increase the Company’s operating costs or operating requirements; environmental litigation that impacts customer plans or projects; disputes with customers; disputes with vendors; bureaucratic, administrative, operating or court-imposed barriers that prevent or delay vessels in foreign markets from going or remaining on-hire; administrative, judicial or political barriers to exploration and production activities in Mexico, Brazil or other foreign locations; disruption in the timing and/or extent of Mexican offshore activities or changes in law or governmental policy in Mexico that restricts or slows the pace of further development of its offshore oilfields; changes in law or governmental policy or judicial action in Mexico affecting the Company's Mexican registration of vessels; administrative or other legal changes in Mexican cabotage laws; other legal or administrative changes in Mexico that adversely impact planned or expected offshore energy development; unanticipated difficulty in effectively competing in or operating in international markets; less than anticipated subsea infrastructure and field development demand in the Greater GoM Operating Region and other markets affecting the Company's MPSVs; sustained vessel over capacity for existing demand levels in the markets in which the Company competes; economic and geopolitical risks; weather-related risks; upon a return to improved operating conditions, the shortage of or the inability to attract and retain qualified personnel, when needed, including vessel personnel for active vessels or vessels the Company may reactivate or acquire; any success in unionizing any of the Company's U.S. fleet personnel; regulatory risks; the repeal or administrative weakening of the Jones Act or adverse changes in the interpretation of the Jones Act; drydocking delays and cost overruns and related risks; vessel accidents, pollution incidents or other events resulting in lost revenue, fines,

36

penalties or other expenses that are unrecoverable from insurance policies or other third parties; unexpected litigation and insurance expenses; other industry risks; fluctuations in foreign currency valuations compared to the U.S. dollar and risks associated with expanded foreign operations, such as non-compliance with or the unanticipated effect of tax laws, customs laws, immigration laws, or other legislation that result in higher than anticipated tax rates or other costs; the inability to repatriate foreign-sourced earnings and profits; the possible loss or material limitation of the Company's tax net operating loss carryforwards and other attributes due to a change in control, as defined in Section 382 of the Internal Revenue Code; or the inability of the Company to refinance or otherwise retire certain funded debt obligations that come due in 2020 and 2021; the potential for any impairment charges that could arise in the future and that would reduce the Company’s consolidated net tangible assets which, in turn, would further limit the Company’s ability to grant certain liens, make certain investments, and incur certain debt permitted under the Company’s senior notes indentures and term loan agreements; or an adverse decision in any potential dispute involving the permissibility of the exchange of 2020 senior notes for second-lien term loans due February 2025. In addition, the Company’s future results may be impacted by adverse economic conditions, such as inflation, deflation, lack of liquidity in the capital markets or an increase in interest rates, that may negatively affect it or parties with whom it does business resulting in their non-payment or inability to perform obligations owed to the Company, such as the failure of customers to fulfill their contractual obligations, if and when required. Should one or more of the foregoing risks or uncertainties materialize in a way that negatively impacts the Company, or should the Company’s underlying assumptions prove incorrect, the Company’s actual results may vary materially from those anticipated in its forward-looking statements, and its business, financial condition and results of operations could be materially and adversely affected and, if sufficiently severe, could result in noncompliance with certain covenants of the Company's existing indebtedness. Additional factors that you should consider are set forth in detail in the “Risk Factors” section of the Company's most recent Annual Report on Form 10-K as well as other filings the Company has made and will make with the Securities and Exchange Commission which, after their filing, can be found on the Company’s website, www.hornbeckoffshore.com.

PART II—OTHER INFORMATION

Item 1—Legal Proceedings

On January 22, 2016, the Company initiated an arbitration demand in accordance with the vessel construction agreement dated November 14, 2011 with VT Halter Marine, Inc., or Halter, to construct ten 300 class OSVs as part of the Company’s fifth OSV newbuild program. On October 21, 2019, the arbitration panel awarded damages in the amount of $18.0 million related to the Company’s claims, offset by $2.1 million awarded to Halter for its counterclaims. Terms for the award require payment to be made within 60 days to avoid interest charges. Limited appeal rights are available to the parties.

During the first quarter of 2018, the Company notified Gulf Island Shipyards, LLC, or Gulf Island, the shipyard that was constructing the remaining two vessels in the Company's fifth OSV newbuild program, that it was terminating the construction contracts for such vessels based on the shipyard's statements that it would be more than one year late in the delivery of the vessels, among other reasons. On October 2, 2018, the shipyard filed suit against the Company in the 22nd Judicial District Court for the Parish of St. Tammany in the State of Louisiana. Gulf Island claims that it has the right to complete the vessels or, alternatively, the Company owes Gulf Island compensation for unpaid work. The Company disputes these claims and has asserted counter-claims against Gulf Island seeking to recover liquidated and other damages. The Company has also sued for conversion, claiming that Gulf Island has wrongfully detained the vessels in its possession, which has delayed the Company's ability to contract for their completion at a replacement shipyard. On November 5, 2019, the district court denied a preliminary motion for summary judgment to require the shipyard to release its possession of the vessels. The Company has also sued the sureties that issued performance bonds in respect of the shipbuilding contracts. The Company claims that the sureties wrongfully denied the Company's claims under the bonds and have refused to perform their obligations under the bonds. The Company has also claimed that the sureties' conduct has been in bad faith.

Item 1A—Risk Factors

The Company conducts business with the United States government. The sustainability and growth of this non-oilfield service-offering is affected by the continued employment of certain personnel by the Company. Given the uncertainty surrounding the Company's financial condition, there is a possibility that the Company's government customers may perceive a risk that personnel considered by such customers to be critical may no longer remain employed by the Company. Any action by the government in response to this perceived risk could adversely impact the Company's future business with the government, the growth of such business and any earnings and cash flows generated by such business.

Item 2—Unregistered Sales of Equity Securities and Use of Proceeds

Exhibit 3.5

Amendment No. 2

to the

Fourth Restated Bylaws

of

Hornbeck Offshore Services, Inc.

This Amendment No. 2 (the “Amendment”) to the Fourth Restated Bylaws, as amended by that certain Amendment No. 1 (the “Bylaws”) of Hornbeck Offshore Services, Inc. (the “Company”) effective as of November 7, 2019 (the “Effective Date”), is hereby adopted pursuant to the provisions of Article VII and Article XII, Section 2 of the Company’s Certificate of Incorporation.

1.Article IV, Section 4.13 is hereby added to the Bylaws and shall read as follows:

Section 4.13. Citizenship Determinations. The Board of Directors shall have the power to determine, in the exercise of its good faith judgment, the citizenship of the holders or beneficial owners (or prospective holders or prospective beneficial owners) of any class or series of the Corporation’s capital stock for the purposes of Article Twelve of the Second Restated Certificate of Incorporation of the Corporation. In determining the citizenship of holders or beneficial owners (or prospective holders or prospective beneficial owners) of any class or series of the Corporation’s capital stock, the Board of Directors may rely on the stock transfer records of the Corporation, reports issued by the Depository Trust Company of Segregation Account System 100 holdings, reports filed with the Securities and Exchange Commission, any citizenship certifications required under this Section 4.13 and the written statements and affidavits provided to the Board of Directors by any stockholder (or prospective stockholder) or person acting as fiduciary, agent, nominee or broker for such stockholder (or prospective stockholder). The determination of the citizenship of such stockholder or beneficial owner (or prospective holder or prospective beneficial owner) may also be subject to proof in such other manner as the Board of Directors may deem appropriate pursuant to this Section 4.13 and Article Twelve of the Second Restated Certificate of Incorporation of the Corporation. The determination of the Board of Directors at any time as to the citizenship of such stockholders (or prospective stockholders) shall be conclusive and binding upon the stockholder and beneficial owner (or prospective stockholder or prospective beneficial owner).

In furtherance of the policy set forth in Article Twelve of the Second Restated Certificate of Incorporation of the Corporation, the Board of Directors may require the holder or beneficial owner (or prospective holder or prospective beneficial owner) of shares of any class or series of the Corporation’s capital stock to confirm their citizenship status from time to time in accordance with the provisions of this Section 4.13, and, as a condition to acquiring and having ownership of shares of any class or series of capital stock of the Corporation, every holder or beneficial owner (or prospective holder or prospective beneficial owner) of any such shares must comply with the following provisions:

(a)promptly upon a holder’s or beneficial owner’s acquisition of ownership of five percent or more of the outstanding shares of any class or series of capital stock of the Corporation or upon request by the Board of Directors, a holder must provide to the Corporation a written statement or an affidavit, as specified by the Board of Directors, duly signed, stating the name and address of such holder, the number of shares of each class or series of capital stock of the Corporation owned by such holder as of a recent date, the legal structure of such holder and any beneficial owner, the beneficial owner of the stock if that person is not the holder, a statement as to whether such holder or beneficial owner is an Alien (as defined in the Second Restated Certificate of Incorporation of the Corporation), and such other information required by 46 C.F.R. Part 355 or as required by the Board of Directors; and

(b)every holder of any shares of the Corporation and any beneficial owner of such shares (or prospective holder or prospective beneficial owner) which has provided a statement or affidavit to the Corporation upon, or in anticipation of acquiring ownership of five percent or more of the outstanding shares of any class or series of capital stock of the Corporation or upon request of the Board of Directors, must provide to the Corporation, at any time such holder or beneficial owner (or prospective holder or prospective beneficial owner) becomes an Alien, as promptly as practicable but in no event less than two business days after the date such holder or beneficial owner (or prospective holder or prospective beneficial owner) becomes an Alien, a written statement, duly signed, stating the name and address of holder and beneficial owner (or prospective

holder or prospective beneficial owner), the number of shares of each class or series of capital stock of the Corporation beneficially owned (or anticipated to be owned) by such holder and beneficial owner (or prospective holder or prospective beneficial owner) as of a recent date, the legal structure of such holder and any beneficial owner (or prospective holder or prospective beneficial owner), and a statement as to such change in status of such holder or beneficial owner (or prospective holder or prospective beneficial owner) to an Alien.

The Board of Directors may at any time require reasonable proof, in addition to the citizenship certifications required under this Section 4.13 of the citizenship of a holder or beneficial owner (or prospective holder or prospective beneficial owner) of stock of the Corporation.

In the event that (i) the Board of Directors requests in writing from a holder or beneficial owner of shares of any class or series of the Corporation’s capital stock a statement or affidavit required under this Section 4.13, and (ii) such holder or beneficial owner fails to provide the Corporation with the requested documentation by the date set forth in such written request, then (x) the voting rights of such holder’s and beneficial owner’s shares of the Corporation’s capital stock shall be suspended, and (y) any dividends or other distributions (upon liquidation or otherwise) with respect to such shares shall be paid into an escrow account, until such requested documentation is submitted in form and substance satisfactory to the Board of Directors in its good faith judgment; provided, however, that the Board of Directors, shall have the power, in its sole discretion, to extend the date by which such requested documentation must be provided and/or to waive the application of sub−clauses (x) and/or (y) of this paragraph to any of the shares of such holder or beneficial owner in any particular instance.

In furtherance of the Policy set forth in Article Twelve of the Second Amended Restated Certificate of Incorporation, the Board of Directors, in the exercise of its discretion, may deem any stock as being acquired by an Alien prior to subsequently acquired Alien-owned shares even though the stock was not marked as “Foreign” in the stock records of the Corporation when it was acquired.

Nothing in this Section 4.13 shall preclude the settlement of any transaction entered into through the facilities of the New York Stock Exchange or any other National Securities Exchange or automated inter−dealer quotation system for so long as any class or series of the capital stock of the Corporation is listed on the New York Stock Exchange. The fact that the settlement of any transaction occurs shall not negate the effect of any provision of this Section 4.13 or of Article Twelve of the Second Restated Certificate of Incorporation of the Corporation.

2.Except as expressly amended herein, the Bylaws remain unmodified and in full force and effect.

Asset Impairment Assessment

In accordance with ASC 360, the Company periodically reviews long-lived asset valuations when events or changes in circumstances indicate that an asset’s carrying value may not be recoverable. If indicators of impairment exist, the Company assesses the recoverability of its long-lived assets by comparing the projected future undiscounted cash flows associated with the related long-lived asset group over their remaining estimated useful lives. If the sum of the estimated undiscounted cash flows are less than the carrying amounts of the asset group, the assets are written down to their estimated fair values based on the expected discounted future cash flows or appraised values attributable to the assets. The future cash flows are subjective and are based on the Company’s current assumptions regarding future dayrates, utilization, operating expense, direct overhead, including G&A expense, and recertification costs that could differ from actual results.

During the second quarter of 2016, the Company determined that it observed indicators of impairment related to its vessels. This resulted from the rapid deterioration of its second quarter 2016 operating results, as well as the uncertainty regarding future market conditions and the related impact on the Company's projected operating results. For the purpose of calculating the undiscounted cash flows, the Company grouped its vessels into two groups, OSVs and MPSVs, and used a probability-weighted undiscounted cash flow projection to test for recoverability. Included in the cash flow projections were assumptions related to the current mix of active and stacked vessels, the timing of stacked vessels returning to active status along with projected dayrates, operating expenses and overhead expenses related to each of the groupings.

While the Company has not observed any new impairment indicators since 2016, it has reviewed and updated, as necessary, the assumptions used in determining its undiscounted cash flow projections for each asset group to reflect current market conditions. After reviewing the results of these projections, which were last updated in 2019, the Company determined that each of its asset groups continue to have sufficient projected undiscounted cash flows to recover the remaining book value of the Company's long-lived assets within such group.

Vessel Construction

During the first quarter of 2018, the Company notified the shipyard that was constructing the remaining two vessels in the Company's fifth OSV newbuild program that it was terminating the construction contracts for such vessels based on the shipyard's statements that it would be more than one year late in the delivery of the vessels, among other reasons. On October 2, 2018, the shipyard filed suit against the Company in the 22nd Judicial District Court for the Parish of St. Tammany in the State of Louisiana, or the Gulf Island Litigation. The shipyard claims that the Company's termination was improper and that the shipyard should be permitted to complete construction of the vessels. Alternatively, the shipyard asserts that if the termination was proper, the Company would owe the shipyard compensation for unpaid work. The Company has responded to the suit and has alleged counter-claims. The Company intends to vigorously defend against the shipyard’s claims and considers them to be without merit. The shipyard has frustrated the Company's ability to complete the vessels at a replacement shipyard by asserting that it has possessory rights over the vessels. The Company disputes these asserted possessory rights and believes that the detention of the vessels, over which the Company has title, is wrongful. On November 5, 2019, the district court denied a preliminary motion for summary judgment to require the shipyard to release its possession of the vessels, which may delay further the ability to complete the vessels at a completion shipyard. Because of the shipyard's detention of the vessels, the timeframe in which the vessels can be completed at a replacement shipyard is also uncertain. The Company received performance bonds from sureties. The sureties have denied the Company's claim under the bonds, but did authorize the Company to select a completion yard and, subject to a reservation of rights, offered to fund the cost to complete the vessels in excess of their contract price of up to the full amount of the performance bond. The Company rejected the sureties' conditional and non-conforming offer.

As of the date of termination of the construction contracts, these two remaining vessels, both of which are domestic 400 class MPSVs, were projected to be delivered in the second and third quarters of 2019, respectively. These projected delivery dates were subsequently amended, for guidance purposes, to be the second and third quarters of 2020. Due to the continued uncertainty of the timing and location of future construction activities, the Company is now updating its forward guidance for the delivery dates related to these vessels to be the second and third quarters of 2021, respectively. However, the timing of the remaining construction draws remains subject to change commensurate with any potential further delays in the delivery dates of such vessels. The cost of this nearly completed 24-vessel newbuild program, before construction period interest, is expected to be approximately $1,335.0 million, of which $22.9 million and $35.8 million are currently expected to be incurred in fiscal 2020 and fiscal 2021, respectively. The foregoing amounts do not reflect any potential additional payments to the shipyard in respect of the aforementioned claim. From the inception of this program through September 30, 2019, the Company had incurred $1,276.3 million, or 95.6%, of total expected project costs.

Contingencies

In the normal course of its business, the Company becomes involved in various claims and legal proceedings in which monetary damages are sought. It is management's opinion that the Company's liability, if any, under such claims or proceedings would not materially affect the Company's financial position or results of operations. The Company insures against losses relating to its vessels, pollution and third party liabilities, including claims by employees under Section 33 of the Merchant Marine Act of 1920, or the Jones Act. Third party liabilities and pollution claims that relate to vessel operations are covered by the Company’s entry in a mutual protection and indemnity association, or P&I Club, as well as by marine liability policies in excess of the P&I Club’s coverage. The Company provides reserves for any individual claim deductibles for which the Company remains responsible by using an estimation process that considers Company-specific and industry data, as well as management’s experience, assumptions and consultation with outside counsel. As additional information becomes available, the Company will assess the potential liability related to its pending claims and revise its estimates. Although historically revisions to such estimates have not been material, changes in estimates of the potential liability could materially impact the Company’s results of operations, financial position or cash flows.

Going Concern

Going Concern

Since the second half of 2014, the offshore oil service sector has experienced difficult operating conditions due to the reduced price of oil. This low oil price environment caused many of the Company's customers to reduce their budgets for the worldwide exploration or production of oil. This reduced spending has negatively impacted the Company's financial results. As discussed in Note 8, the Company's 2020 senior notes and 2021 senior notes mature in April 2020 and March 2021, respectively. The maturity of the Company’s 2020 senior notes now falls within the twelve-month period following the issuance of these financial statements for which the Company is required to evaluate as part of its assessment of its ability to continue as a going concern. Management of the Company continues to believe it has adequate liquidity to fund its operations up until the maturity of the 2020 senior notes. However, absent the combination of a significant recovery of market conditions such that cash flow from operations were to increase materially from currently projected levels, coupled with the refinancing and/or further management of its funded debt obligations, the Company does not currently expect to have sufficient liquidity to repay the full amount of the 2020 senior notes and the 2021 senior notes as they mature in 2020 and 2021, respectively. Management continues to implement its on-going plan to address its maturities as they become due, including efforts in connection with the refinancing of its 2020 senior notes. The closing of the $100 million senior credit facility in June 2019 was the latest step in that iterative process. Based on continuing discussions with existing and potential lenders, management is cautiously optimistic that it will be able to successfully implement this plan. However, management recognizes that its plan depends on the actions of these third parties, including reaching an agreement with existing senior note holders and/or obtaining new sources of liquidity, and, therefore, the Company is unable at this time to conclude that such plan is reasonably certain of being achieved. Accordingly, given the uncertainty with respect to the Company’s ability to pay its 2020 senior notes in full as they become due, the Company acknowledges that substantial doubt exists regarding its ability to continue as a going concern. There can be no assurance that cash flows from operations will increase materially or that the Company will succeed in reaching agreements with its senior note holders or accessing new capital to pay the 2020 senior notes in full as they become due in April 2020.

The accompanying consolidated financial statements have been prepared assuming the Company will continue as a going concern, which contemplates continuity of operations, realization of assets and the satisfaction of liabilities in the normal course of business for the twelve-month period following the date of these consolidated financial statements. As such, the accompanying consolidated financial statements do not include any adjustments relating to the recoverability and classification of assets and their carrying amounts, or the amount and classification of liabilities that may result should the Company be unable to continue as a going concern.

Earnings Per Share [Abstract]

Loss Per Share

Loss per share

Basic and Diluted loss per common share was calculated by dividing net loss by the weighted average number of common shares outstanding during the period. Weighted average number of common shares outstanding was calculated by using the sum of the shares determined on a daily basis divided by the number of days in the period.

The table below reconciles the Company’s loss per share (in thousands, except for per share data): 

	Three Months Ended    September 30,						Nine Months Ended   September 30,

Diluted loss per common share	$	(1.09	)	$	(0.83	)	$	(2.90	)	$	(2.53	)

(1) Due to a net loss, the Company excluded from the calculation of loss per share the effect of equity awards representing the rights to acquire 4,683 and 3,659 shares of common stock for the three and nine months ended September 30, 2019, respectively and 529 shares and 602 shares of common stock for the three and nine months ended September 30, 2018, respectively.

(2) For the nine months ended September 30, 2019 and 2018 and for the three months ended September 2018, the 2019 convertible senior notes were not dilutive, as the average price of the Company’s stock was less than the effective conversion price of such notes. In September 2019, the Company repaid the remaining balance of the 2019 convertible senior notes in full upon their maturity. See Note 8 for further discussion. It was the Company's stated intention to redeem the principal amount of its 2019 convertible senior notes in cash and the Company used the treasury method for determining potential dilution in the diluted earnings per share computation.

(3) Dilutive unvested restricted stock units are expected to fluctuate from quarter to quarter depending on the Company’s performance compared to a predetermined set of performance criteria. See Note 9 to these financial statements for further information regarding certain of the Company’s restricted stock grants.

The Company’s stock-based incentive compensation plan now covers a maximum of 11.95 million shares of common stock that allows the Company to grant restricted stock awards, restricted stock unit awards, or collectively restricted stock, stock options, stock appreciation rights and fully-vested common stock to employees and directors. As a result of the approval to increase the number of shares available under this plan, the Company, which has the sole discretion in determining the method of settlement for awards granted under the plan, now has the ability and intent to settle these awards using available shares. Accordingly, the classification of and accounting for 5.1 million outstanding phantom stock units, or PSUs, and 1.6 million stock appreciation rights, or SARs, were modified from cash-settled to stock-settled during the second quarter of 2019. These outstanding awards were granted to Company executives in 2017, 2018 and 2019 and to non-executive employees in 2019. After these settlement modifications were completed, the Company has only 0.2 million awards outstanding that will settle in cash on their respective vesting dates. The remaining vesting provisions of the modified awards were not impacted and, therefore, the Company determined the fair value of the awards on the date of the modification was the same as the date prior to the modification. There was no additional compensation expense recognized at the time of modification. As of September 30, 2019, taking into account the outstanding awards now anticipated to be stock-settled, the Company has 0.7 million shares of common stock available to be granted under such plan.

Restricted Stock

During the nine months ended September 30, 2019, the Company granted 2.4 million time-based PSUs. The compensation expense related to time-based PSUs is amortized over a vesting period of up to three years and is determined based on the market price of the Company’s stock on the date of grant applied to the total shares that are expected to fully vest. All PSUs that remain cash-settled are re-measured quarterly and classified as a liability, due to the originally intended settlement of these awards in cash. As a result of the stockholder approval to increase the number of shares available under its long-term incentive compensation plan, the Company now has the ability to settle certain previously granted PSUs in shares. As such, the value of these awards was determined on the modification date and such expense will not vary in future periods.

In addition to the PSUs granted in 2019, the Company granted performance-based and time-based restricted stock units and phantom restricted stock units in prior years. The PSUs granted in prior years to non-executive employees were not impacted by the June 2019 modification. During the nine months ended September 30, 2019, the Company issued 292,715 shares of common stock due to vestings of restricted stock units and employee purchases under the Company's Employee Stock Purchase Plan.

Stock Appreciation Rights

During the nine months ended September 30, 2019, the Company granted 1.6 million SARs. The SARs vest and become exercisable in three equal annual installments on each of the 1st, 2nd and 3rd anniversaries of the grant date and have a ten-year life. The SARs represent the right to receive, upon exercise, a number of shares of Company common stock, cash, or a combination thereof, at the election of the Company, equal to the product of the aggregate number of shares of Company common stock with respect to which the SAR is exercised and the excess of the fair market value of a share of Company common stock as of the date of exercise over the grant price of $1.38.

On June 20, 2019, the Company determined that it would settle its outstanding SARs in equity rather than cash and such awards are now accounted for as stock-settled SARs. All of the remaining vesting provisions of the SARs are unchanged. The Company estimated the fair value of each SAR on the modification date using the Black-Scholes option-pricing model. As of the modification date, the fair value for the outstanding SARs was $1.02 per share granted.

The following assumptions were used to value SARs on the modification date:

Expected volatility	89.1	%
Expected life	6.0	years
Risk-free interest rate	1.9	%
Expected dividend yield	—	%

The risk-free interest rate used to value SARs is based on the U.S. Treasury yield curve in effect at the time of grant with maturity dates that coincide with the expected life of the SARs. The Company used the simplified method under GAAP to determine the expected life, since this is the first time the Company issued SARs. The Company's assumption for volatility is based on its historical volatility calculated on the grant date.

The impact of stock-based compensation expense charges on the Company’s operating results are reflected in the table below (in thousands, except for per share data):

Recent Accounting Pronouncements

Recent Accounting Pronouncements

Standard	Description	Required Date of Adoption	Effect on the financial statements and other significant matters
Standards that have been adopted
ASU No. 2016-02, "Leases" (Topic 842)	This standard requires lessees to recognize a lease liability and a right-of-use asset for all leases (with the exception of short-term leases) at the commencement date. ASU 2016-02 requires a modified retrospective application. Early adoption is permitted.	January 1, 2019	The Company adopted this ASU effective January 1, 2019. See further discussion below and in footnote 12.
ASU No. 2018-02, "Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income"	This standard allows companies to reclassify items in accumulated other comprehensive income to retained earnings for stranded tax effects resulting from The Tax Cuts and Jobs Act.	January 1, 2019	The Company adopted ASU No. 2018-02 on January 1, 2019. This adoption had no material impact on its consolidated financial statements.
ASU No. 2018-09, "Codification Improvements"	This standard provides clarification, corrects errors in and makes minor improvements to various ASC topics. Many of the amendments in this update have transition guidance with effective dates for annual periods beginning after December 15, 2018, and some amendments do not require transition guidance and are effective upon issuance of this update.	January 1, 2019	The Company adopted ASU No. 2018-09 on January 1, 2019. This adoption had no material impact on its consolidated financial statements.
ASU No. 2018-11, "Leases" (Topic 842): Targeted Improvements	This standard provides for the election of transition methods between the modified retrospective method and the optional transition relief method. The modified retrospective method is applied to all prior reporting periods presented with a cumulative-effect adjustment recorded in the earliest comparative period while the optional transition relief method is applied beginning in the period of adoption with a cumulative-effect adjustment recorded in such period. Also, this standard allows lessors to elect to not separate non-lease components from the associated lease components if certain criteria are met.	January 1, 2019	The Company adopted ASU No. 2018-11 on January 1, 2019. See further discussion below.

Standards that have not been adopted
ASU No. 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments"	This standard requires measurement and recognition of expected credit losses for financial assets held. ASU No. 2016-13 requires modified retrospective application. Early adoption is permitted.	January 1, 2023	The Company believes that the implementation of this new guidance will not have a material impact on its consolidated financial statements.

ASC 842, Leases

Lessee Accounting

In February 2016, the Financial Accounting Standards Board, or FASB, issued ASU 2016-02, Leases, which requires lessees to recognize a right-of-use, or ROU, asset and a lease obligation for all leases. This ASU became effective for the Company for its annual reporting period beginning January 1, 2019, including interim periods within that reporting period. The Company adopted the standard using a modified retrospective approach with the effective date of the standard as the date of initial application.

The Company elected the package of practical expedients permitted under the transition guidance within the standard, which eliminates the reassessment of past leases, classification and initial direct costs. For leases with a term of twelve months or less, the Company has made a policy election in which the ROU asset and lease liability will not be recognized on its balance sheet.

As a result of the Company's adoption of this new standard, it recorded ROU assets of $24.7 million and lease liabilities of $27.7 million. The adoption of the standard did not have an impact on the Company's equity and will not have a material impact on the Company's results of operations and cash flows.

Lessor Accounting

Under ASU 2018-11, a lessor may elect to combine lease and non-lease components provided that the non-lease component(s) otherwise would be accounted for under the new revenue guidance in ASC 606 and both of the following conditions are met:

• The timing and pattern of transfer for the lease component are the same as those for the non-lease components associated with that lease component.

• The lease component, if accounted for separately, would be classified as an operating lease.

When the above conditions are met, the entity will need to assess predominance. If the non-lease components are predominant, the entity accounts for the combined component under ASC 606; otherwise, the entity accounts for the combined component under ASC 842.

After review of its revenue streams, the Company has concluded that the non-lease component of its revenue is predominant, and that both of the criteria above are met. Therefore, the Company has adopted the new transition options and combines lease and non-lease revenues. The Company recognizes revenue based on the non-lease component under ASC 606, as it has concluded that the non-lease component is the predominant component. The adoption of ASU 2018-11 on January 1, 2019 did not change the timing or amounts of revenues recognized by the Company.

Acquisition of Vessels [Abstract]

Acquisition of Vessels

Acquisition of Vessels

On May 18, 2018, the Company completed the acquisition of four high-spec Jones Act-qualified OSVs and related equipment from Aries Marine Corporation and certain of its affiliates for $40.9 million in cash, inclusive of $4.0 million related to a non-compete intangible asset that is being amortized over the life of such asset, or two years. Also included in this transaction was the cost of fuel and lube inventory and transactions fees. The acquired vessels were all U.S.-flagged and are comprised of two 300 class OSVs and two 280 class OSVs. Subsequent to the acquisition, these four vessels have been foreign-flagged. The Company determined that substantially all of the fair value of the assets acquired are concentrated in a group of similar identifiable assets and, therefore, has accounted for such transaction as an asset acquisition under ASU 2017-01.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

The effective tax benefit rate for the nine months ended September 30, 2019 and 2018 was 21.9% and 18.9%, respectively. The Company's effective tax rate differs from the federal statutory rate due to the establishment of valuation allowances in 2019 and 2018 for state net operating loss, foreign tax credit carryforwards, and nondeductible interest based upon management's conclusion that it is more likely than not such losses and credits will not be realized by their expiration dates. The Company's income tax benefit rate for the nine months ended September 30, 2019 was higher than the benefit rate from the nine months ended September 30, 2018, because of the reversal of a portion of valuation allowances on state net operating loss carryforwards that the Company now believes will be utilized, due to state law changes in June 2019.

During the nine months ended September 30, 2019, the Company adopted ASU 2018-02 and has elected to reclassify the stranded income tax effects of the Tax Cuts and Jobs Act from accumulated comprehensive income to retained earnings. As a result, a reduction in retained earnings and an increase in accumulated other comprehensive income of $1.9 million was recorded in the nine months ended September 30, 2019.

Diluted loss per common share	$	(1.09	)	$	(0.83	)	$	(2.90	)	$	(2.53	)

(1) Due to a net loss, the Company excluded from the calculation of loss per share the effect of equity awards representing the rights to acquire 4,683 and 3,659 shares of common stock for the three and nine months ended September 30, 2019, respectively and 529 shares and 602 shares of common stock for the three and nine months ended September 30, 2018, respectively.

(2) For the nine months ended September 30, 2019 and 2018 and for the three months ended September 2018, the 2019 convertible senior notes were not dilutive, as the average price of the Company’s stock was less than the effective conversion price of such notes. In September 2019, the Company repaid the remaining balance of the 2019 convertible senior notes in full upon their maturity. See Note 8 for further discussion. It was the Company's stated intention to redeem the principal amount of its 2019 convertible senior notes in cash and the Company used the treasury method for determining potential dilution in the diluted earnings per share computation.

(3) Dilutive unvested restricted stock units are expected to fluctuate from quarter to quarter depending on the Company’s performance compared to a predetermined set of performance criteria. See Note 9 to these financial statements for further information regarding certain of the Company’s restricted stock grants.

Leases [Abstract]

Leases

Leases

The Company determines if an agreement is a lease or contains a lease at inception. The lease term may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise the option. ROU assets and the corresponding lease liabilities are recorded at the commencement date based on the present value of lease payments over the expected lease term. The Company uses its incremental borrowing rate, which would be the rate incurred to borrow on a collateralized basis over a similar term in a similar economic environment, to calculate the present value of lease payments.

The Company is obligated under certain operating leases for shore-based facilities, office space and temporary housing. Such leases will often include options to extend the lease and the Company will include option periods that, on commencement date, it is reasonably likely that it will exercise. Some leases may require variable lease payments such as real estate taxes and maintenance expenses. These costs are expensed in the period in which they are incurred. None of the Company's leases contain any residual value guarantees. The Company recorded $3.0 million of expense related to leases in general and administrative and operating expenses during the nine months ended September 30, 2019. The expense recorded for short-term leases was $0.4 million during the nine months ended September 30, 2019.

During the nine months ended September 30, 2019, the Company recorded operating cash outflows from operating leases of $2.7 million.

Annual maturities of operating lease liabilities under non-cancelable leases with terms in excess of one year, as of September 30, 2019, are as follows (in thousands):

Revenue from Contract with Customer [Abstract]

Revenues from Contracts with Customers

Revenues from Contracts with Customers

Effective January 1, 2018, the Company adopted ASU 2014-09, Revenue from Contracts with Customers, using the modified retrospective method. The adoption of this standard did not have a material impact on the Company's financial position or results of operations. Accordingly, the Company did not make an adjustment to the opening balance of retained earnings in order to account for the implementation of the new requirements of this standard, and it did not restate prior period information for the effects of the new standard.     

The services that are provided by the Company represent a single performance obligation under our contracts that are satisfied at a point in time or over time. Revenues are earned primarily by (1) chartering the Company's vessels, including the operation of such vessels, (2) providing vessel management services to third party vessel owners, and (3) providing shore-based port facility services, including the rental of land. The services generating these revenue streams are provided to customers based upon contracts that include fixed or determinable prices and do not generally include right of return or other significant post-delivery obligations. The Company's vessel revenues, vessel management revenues and port facility revenues are recognized either at a point in time or over the passage of time when the customer has received or is receiving the benefit from the applicable service. Revenues are recognized when the performance obligations are satisfied in accordance with contractual terms and in an amount that reflects the consideration that the Company expects to be entitled to in exchange for the services rendered or rentals provided. Revenues are recognized net of any taxes collected from customers, which are subsequently remitted to governmental authorities. Invoices are typically billed to our customers on a monthly basis and payment terms on customer invoices typically range 30 to 60 days.

A performance obligation under contracts with the Company's customers to render services is the unit of account under Topic 606. The Company accounts for services rendered separately if they are distinct and the service is separately identifiable from other items provided to a customer and if a customer can benefit from the services rendered provided on its own or with other resources that are readily available to the customer. A contract's transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied.

As of September 30, 2019, the Company has certain remaining performance obligations representing contracted vessel revenues for which work has not been performed and such contracts have an original expected duration of more than one year. As of September 30, 2019, the aggregate amount of the transaction price allocated to remaining performance obligations for such contracts was $5.9 million, of which $1.5 million and $4.4 million are expected to be recognized in 2019 and 2020, respectively. The Company has elected to apply the optional exemption for the disclosure of the remaining performance obligations for any of its revenue streams that are expected to have a duration of one year or less and, therefore, such amounts have not been disclosed.

Senior Credit Facility

On June 28, 2019, the Company entered into a $100.0 million senior secured asset-based revolving credit facility, or the senior credit facility. The senior credit facility is guaranteed by certain of the Company's domestic and foreign subsidiaries and contains customary representations and warranties, covenants and events of default. The fully-funded senior credit facility is secured by first-priority liens on receivables, certain restricted and unrestricted cash accounts and related assets. The senior credit facility is comprised of two tranches that will rebalance each month based on the variable receivable-backed borrowing base. The unrestricted receivables-backed tranche will mature in 2022, whereas the restricted cash-backed tranche will mature in 2025. The receivables-backed tranche may be used, subject to the completion of applicable eligibility review procedures, for working capital and general corporate purposes, including the refinancing or repayment of existing debt, subject to, among other things, compliance with certain requirements. The cash-backed tranche may, over time, rebalance to the receivables-backed tranche as eligible receivables increase and may be refinanced over time.

Borrowings under the senior credit facility accrue interest at a floating-rate LIBOR plus a fixed spread of 5.00% for the life of the facility. The Company may, at its option from time to time, prepay loans under either tranche of the senior credit facility. Fifty percent of such loans available under the senior credit facility is subject to a prepayment premium (i) at 103% of the principal amount repaid if such repayment occurs on or prior to June 28, 2020; (ii) at 102% of the principal amount repaid if such repayment occurs on or prior to June 28, 2021; (iii) at 101% of the principal amount repaid if such repayment occurs on or prior to December 28, 2021 and (iv) at 100% of the principal amount repaid if such repayment occurs after December 28, 2021, with such premiums subject to adjustments downward under certain circumstances. The other fifty percent of such loans may be repaid at any time without prepayment penalty.

On September 30, 2019, the Company's restricted cash balance under the senior credit facility was $56.2 million. The Company classifies cash as restricted when there are legal or contractual restrictions on its withdrawal or usage.

First-Lien Term Loans

On June 15, 2017, the Company entered into the first lien term loan agreement (as amended, amended and restated, supplemented or otherwise modified from time to time, the First Lien Term Loan Agreement), by and among the Company, as Parent Borrower, Hornbeck Offshore Services, LLC, or HOS, as Co-Borrower, certain holders of the Company’s then outstanding notes, or the First-Lien Initial Lenders, and Wilmington Trust, National Association, as Administrative Agent and Collateral Agent for the lenders that initially provided for $300 million of first-lien delayed-draw term loans, or the first-lien term loans. On March 1, 2019, the Company entered into Incremental First Lien Term Loan Joinder Agreements with such parties, including certain existing as well as additional lenders, to borrow an additional $50.0 million of first-lien term loans, or the incremental first-lien term loans, under the First Lien Term Loan Agreement, including approximately $30.1 million in cash of new financing. On March 1, 2019, the Company exchanged approximately $21.0 million in face value of its 2019 convertible senior notes in a privately negotiated debt-for-debt exchange for the remaining approximately $19.9 million of incremental first-lien term loans. In accordance with applicable accounting guidance, this debt-for-debt exchange was accounted for as a debt modification. As a result, the Company recorded a loss on early extinguishment of debt of $1.3 million ($1.1 million or $0.03 per diluted share after-tax) due to deal costs associated with the exchange. The incremental first-lien term loans have the same terms applicable to the first-lien term loans originally issued under the existing First Lien Term Loan Agreement.

The Company can use the amounts under the first-lien term loans for working capital and general corporate purposes, including acquisitions and/or the refinancing of existing debt, subject to, among other things, compliance with certain covenants requiring the Company to maintain access to liquidity (cash and credit availability) of $25.0 million at all times. The minimum liquidity level required for prepayment of the Company’s existing indebtedness and/or certain other restricted payments is $65.0 million.

The first-lien term loans are guaranteed by certain of the Company's domestic and foreign subsidiaries and are collateralized on a first-lien basis by certain deposit and securities accounts, 46 domestic high-spec OSVs and MPSVs and nine foreign high-spec OSVs, including a security interest in two pending MPSV newbuilds, and associated personalty, as well as by second-priority liens on receivables, certain unrestricted cash accounts and related assets that secure the senior credit facility on a first-lien basis.

Borrowings accrue interest, at the Company’s option, at either:

• an adjusted London Interbank Offered Rate (subject to a 1.00% floor) plus (a) 6.00% during the first year of the first-lien term loans, (b) 6.50% during the second year of the first-lien term loans, (c) 7.00% during the third year of the first-lien term loans, (d) 7.25% during the fourth year of the first-lien term loans, and (e) 7.50% thereafter; or

• the greatest of (a) the prime rate announced by The Wall Street Journal, (b) the Federal Funds Effective Rate in effect on such day plus 1/2 of 1%, and (c) the London Interbank Offered Rate plus, 1%, plus, for either (a), (b), or (c), a margin of (i) 5.00% during the first year of the first-lien term loans, (ii) 5.50% during the second year of the first-lien term loans, (iii) 6.00% during the third year of the first-lien term loans, (iv) 6.25% during the fourth year of the first-lien term loans, and (v) 6.50% thereafter.

Second-Lien Term Loans

In February and March 2019, the Company completed two private offers and exchanged an aggregate of $142.6 million in face value of its 2020 senior notes for $121.2 million of second-lien term loans due 2025, or second-lien term loans, of the Company and the Co-Borrower. In accordance with applicable accounting guidance, this debt-for-debt exchange was accounted for as a debt modification. As a result, the Company recorded a loss on early extinguishment of debt of $2.4 million ($1.9 million or $0.05 per diluted share after-tax) primarily related to deal costs associated with the exchange. As contemplated by and provided for under the agreement governing the first-lien term loans, the second-lien term loans were made pursuant to a Second Lien Term Loan Agreement entered into by the Company, the Co-Borrower, the lenders party thereto and the Administrative Agent and Collateral Agent. The second-lien term loans have a maturity date of February 7, 2025 and bear interest at a fixed rate per annum of 9.50%. The second-lien term loans are guaranteed by certain of the Company’s domestic and foreign subsidiaries and are collateralized on a second-lien basis, subject to certain permitted liens, by a second-priority interest in the same collateral securing the Company’s first-lien term loans on a first-lien basis and third priority liens on receivables, certain unrestricted cash accounts and related assets that secure the senior credit facility on a first-lien basis.

Convertible Note Repurchases and Repayment

During the nine months ended September 30, 2019, the Company completed a series of private transactions for the repurchase of $52.9 million in face value of its outstanding 2019 convertible senior notes for an aggregate total of $47.6 million of cash. The Company recorded a gain on early extinguishment of debt of $3.6 million ($2.9 million or $0.08 per diluted share after-tax), which was comprised of a $5.6 million gain on the repurchase, offset in part by the write-off of $2.0 million of original issue discount, deal costs and unamortized financing costs related to the notes repurchased.

On September 3, 2019, the Company repaid the remaining balance of $25.8 million in face value of its 2019 convertible senior notes in full upon their maturity, plus accrued and unpaid interest thereon, in accordance with the terms of the indenture governing such notes. The retirement of this debt was funded with cash on hand.

The agreements governing the first-lien term loans and the second-lien term loans, the senior credit facility and the indentures governing the Company's 2020 senior notes and 2021 senior notes impose certain restrictions on the Company. Such restrictions affect, and in many cases limit or prohibit, among other things, the Company's ability to incur additional indebtedness, make capital expenditures, redeem equity, create liens, sell assets and make dividend or other restricted payments.

The Company estimates the fair value of its 2020 senior notes, 2021 senior notes, the first-lien term loans and the second-lien term loans by primarily using quoted market prices. Given the observability of the inputs to these estimates, the Company has assigned a Level 2 of the three-level valuation hierarchy. The interest rate on the senior credit facility is variable and the Company has concluded that face value approximates fair value of such facility as of September 30, 2019.

As of the dates indicated below, the Company had the following face values, carrying values and fair values (in thousands):

Capitalized Interest

During the first quarter of 2018, the Company notified the shipyard that was constructing the remaining two vessels in the Company's fifth OSV newbuild program that it was terminating the construction contracts for such vessels. The Company did not capitalize any of its interest costs during the nine months ended September 30, 2019. Upon recommencement of construction of such vessels, the Company intends to resume capitalization of related interest costs. During the nine months ended September 30, 2018, the Company capitalized approximately $2.3 million of interest costs related to the construction of vessels.
