Exhibit 99.1

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

The following unaudited pro forma condensed combined financial information and the accompanying notes (the “Pro Forma Financial Information”) are presented to illustrate the estimated effects of the Mergers (as defined below), which were completed on September 1, 2026 (the “closing date”), pursuant to the Agreement and Plan of Merger, dated April 22, 2026 (the “merger agreement”), by and among Helix Energy Solutions Group, Inc., a Minnesota corporation (“Legacy Helix”), Odyssey Sub, Inc. (“Parent Sub”), Hercules Sub LLC (“LLC Sub”) and Hornbeck Offshore Services, Inc., a Delaware corporation (“Legacy Hornbeck”). Pursuant to the merger agreement, on the closing date, (i) Legacy Helix converted from a Minnesota corporation to a Delaware corporation (the “Conversion”); (ii) following the Conversion, Parent Sub merged with and into Legacy Hornbeck (the “First Company Merger” and the effective time of such merger, the “Effective Time”), with Legacy Hornbeck surviving the First Company Merger as a wholly owned subsidiary of Legacy Helix (Legacy Hornbeck, as the surviving corporation in the First Company Merger, the “Surviving Corporation”); and (iii) one minute after the Effective Time, the Surviving Corporation merged with and into LLC Sub (the “Second Company Merger” and, together with the First Company Merger, the “Mergers”), with LLC Sub surviving the Second Company Merger as a wholly owned subsidiary of Legacy Helix. The Mergers are accounted for as a reverse acquisition, where Legacy Hornbeck, the legal acquiree, is determined to be the accounting acquirer of Legacy Helix. Refer to Note 1. Following the Mergers, Legacy Helix changed the name of the combined company to Hornbeck Offshore Services, Inc. (the “Company”), and the Company’s common stock continues to trade on the New York Stock Exchange under the new name and ticker symbol “HOS”.

The following transactions occurred in accordance with the merger agreement at the Effective Time of the Mergers:

 

   

Legacy Helix and Legacy Hornbeck securityholders own approximately 45% and 55%, respectively, of the Company, on a fully diluted basis.

 

   

Each issued and outstanding share of Legacy Hornbeck common stock was converted into the right to receive 10.27167 shares (the “exchange ratio”) of the Company’s common stock, par value $0.00001 per share. No fractional shares of the Company’s common stock were issued; instead, stockholders became entitled to receive cash payments for the value of any fractional shares that would otherwise have been payable.

 

   

Outstanding Legacy Hornbeck restricted stock units (“RSUs”) and performance stock units (“PSUs”) generally vested and were settled in shares of the Company’s common stock. The number of shares underlying each award was determined by multiplying the number of shares subject to such award by the exchange ratio. PSUs were rounded up or down to the nearest whole share, while RSUs were rounded down to the nearest whole share. Certain RSUs held by non-employee directors were cash-settled. A subset of executive RSUs and PSUs granted in connection with the closing of the Mergers remain outstanding and continue to be subject to post-closing vesting requirements.

 

   

Each outstanding Legacy Hornbeck option became fully vested and converted into an option of the Company’s common stock, with the number of shares underlying each converted option determined by applying the exchange ratio rounded down to the nearest whole share, and the exercise price adjusted by dividing by the exchange ratio rounded up to the nearest whole cent. Certain of the converted options were exercised at closing in accordance with their terms, in exchange for shares of the Company’s common stock. The other converted options continue to be outstanding and the holders have the option to exercise such option in accordance with their terms for shares of the Company’s common stock.

 

   

All Legacy Hornbeck warrants (each, a “Creditor Warrant”) issued pursuant to the Creditor Warrant Agreement, dated as of September 4, 2020, as amended, were settled in shares of the Company’s common stock.

 

   

Each Legacy Hornbeck warrant (each, a “Jones Act Warrant”) issued pursuant to the Jones Act Warrant Agreement, dated as of September 4, 2020, as amended and restated, was assumed by the Company and became exercisable for a number of shares of the Company’s common stock adjusted to reflect the exchange ratio, with the applicable exercise price remaining unchanged.

 

   

Each outstanding Legacy Helix RSU and PSU became fully vested and, pursuant to the election by the Legacy Helix Board prior to the Effective Time and after consultation with the Legacy Hornbeck Board, was settled in cash based on the closing price of Legacy Helix common stock on the trading day immediately preceding the closing date. Each Legacy Helix non-employee director restricted stock award became fully vested and was settled in shares of the Company’s common stock.

The Pro Forma Financial Information has been prepared under the following assumptions:

 

   

The unaudited pro forma condensed combined balance sheet of the Company as of June 30, 2026 assumes that the Mergers had occurred on June 30, 2026.

 

   

The unaudited pro forma condensed combined statements of operations of the Company for the six months ended June 30, 2026 and for the year ended December 31, 2025 assume that the Alliance Disposal (as defined below) and the Mergers had occurred on January 1, 2025, the beginning of the earliest period presented.

The Pro Forma Financial Information has been compiled using, and should be read in conjunction with the following:

 

   

The unaudited condensed consolidated financial statements and notes of Legacy Helix as of and for the six months ended June 30, 2026 included in the Form 10-Q, filed by Legacy Helix with the Securities and Exchange Commission (the “SEC”) on August 6, 2026.

 

   

The audited consolidated financial statements and notes of Legacy Helix as of and for the year ended December 31, 2025, revised and reissued to reflect the presentation of discontinued operations as a result of the sale of its Shallow Water Abandonment reportable segment (the “Alliance Disposal”), which were included in the Form 8-K filed by Legacy Helix with the SEC on August 11, 2026.

 

   

The unaudited condensed consolidated financial statements and notes of Legacy Hornbeck as of and for the six months ended June 30, 2026, included as Exhibit 99.2 to the Company’s Current Report on Form 8-K filed with the SEC on September 1, 2026 (the “Original 8-K”), which is being amended by the accompanying Current Report on Form 8-K/A (“Amendment No. 1”).

 

   

The audited consolidated financial statements and notes of Legacy Hornbeck as of and for the year ended December 31, 2025, included as Exhibit 99.1 to the Original 8-K, which is being amended by the accompanying Amendment No. 1.

The Pro Forma Financial Information is for informational purposes only and is not necessarily indicative of what the actual consolidated results of operations and financial position of the Company would have been had the Mergers taken place on the dates indicated, nor are they indicative of future consolidated results of operations or financial position of the Company. The Pro Forma Financial Information is based on the information available to management at the time of preparation and assumptions that management believes are reasonable and supportable. The pro forma adjustments, which are described in the accompanying notes, may be revised as additional information becomes available and is evaluated. It is likely that the actual adjustments upon the finalization of the purchase price accounting will differ from the pro forma adjustments, and it is possible the differences may be material.

NOTES TO THE UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

 

1.

Basis of Presentation

The Pro Forma Financial Information has been prepared in accordance with Article 11 of Regulation S-X, as amended by the final rule, Release 33-10786 “Amendments to Financial disclosures about Acquired and Disposed Businesses” (“Article 11 of Regulation S-X”), and the assumptions set forth herein. The pro forma adjustments include transaction accounting adjustments, which reflect the application of required accounting for the Mergers and other transactions contemplated by the merger agreement. Article 11 of Regulation S-X permits presentation of reasonably estimable synergies and dis-synergies that have occurred or are reasonably expected to occur (“Management’s Adjustments”). The Company has elected not to present Management’s Adjustments as the specificity of the timing and nature of such items is still under evaluation as of the date of the accompanying Amendment No. 1.

On May 1, 2026, Legacy Helix completed the sale of the Alliance Disposal, which represented a strategic shift and qualified for discontinued operations presentation. Accordingly, the results of operations of the disposed business have been classified as discontinued operations in Legacy Helix’s revised and historical financial statements. The unaudited pro forma condensed combined balance sheet has been prepared as if the Alliance Disposal occurred on June 30, 2026, and the unaudited pro forma condensed combined statements of operations have been prepared as if the Alliance Disposal occurred on January 1, 2025. The balance sheet positions and results of operations attributable to the discontinued operations have been excluded from the “Legacy Helix As Adjusted” amounts, as the disposed business was not a part of the Company as of the closing date.

All dollar figures in this section are presented in thousands, except per share information, unless otherwise stated.

Accounting for the Mergers

The Mergers are accounted for as a business combination and a reverse acquisition pursuant to Accounting Standards Codification Topic 805, Business Combinations (“ASC 805”), where Legacy Hornbeck, the legal acquiree, is determined to be the accounting acquirer of Legacy Helix based upon an evaluation of the following primary factors:

 

   

Legacy Helix and Legacy Hornbeck securityholders own approximately 45% and 55%, respectively, of the Company, on a fully diluted basis.

 

   

The Ares Investor Group, the largest pre-combination stockholder of Legacy Hornbeck, holds the largest minority voting interest of approximately 12% in the Company after the closing date, whereas Legacy Helix’s pre-combination ownership was broadly dispersed among its stockholders.

 

   

The Company’s board of directors consists of seven directors, four of whom were designated by Legacy Hornbeck, including the Chief Executive Officer and President of the Company, and three of whom were designated by Legacy Helix.

 

   

Legacy Hornbeck’s senior management team comprises the majority of the senior management of the Company, including the Chief Executive Officer and President, Chief Financial Officer, General Counsel, and Chief Operating Officer – Marine Transportation and Specialty; and

 

   

The Company operates under the name Hornbeck Offshore Services, Inc., and the ticker symbol of the Company is “HOS.”

Under the reverse acquisition method of accounting, the Company recognized the assets and liabilities of Legacy Helix as of the closing date at their respective fair values, and the excess of the purchase price consideration over the fair value of Legacy Helix’s net assets was recognized as goodwill. Fair value is defined in Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosures (“ASC 820”) as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” Fair value measurements can be highly subjective, and it is possible the application of reasonable judgment could develop different assumptions resulting in a range of alternative estimates using the same facts and circumstances.

Preliminary purchase price consideration

The stock price of Legacy Helix, as an accounting acquiree, is used to measure the consideration transferred in this reverse acquisition, as Legacy Helix’s stock price is more reliably measurable than the value of the equity interest of Legacy Hornbeck, which is a privately held entity. The following table presents the calculation of preliminary purchase price consideration (in thousands, except stock price):

Accounting Policies

Management is in the process of performing a comprehensive review of the two entities’ accounting policies. As a result of the review, management may identify differences between the accounting policies of the two entities which, when confirmed, could have a material impact on the combined financial statements of the Company. Based on an initial analysis, management did not identify differences that would have a material impact on the Pro Forma Financial Information, except for the presentation reclassifications further discussed in Note 3.

Transaction Accounting Adjustments

Explanations of the adjustments to the unaudited condensed combined pro forma financial statements are as follows:

Unaudited Pro Forma Condensed Combined Balance Sheet

 

(A)

Represents the cash payment at closing and settlement of historical accruals related to the long-term cash-based incentive compensation programs at both Legacy Helix and Legacy Hornbeck, Legacy Helix RSUs and PSUs, certain Legacy Hornbeck RSUs held by non-employee directors, Legacy Helix executive severance, and retention bonuses in connection with the Mergers.

 

(B)

Represents preliminary fair value adjustments to Legacy Helix’s historical financial position, including Property, plant and equipment, net; U.S. Maritime Administration (“MARAD”) Debt; Senior Notes due 2029; Operating lease right-of-use assets; asset retirement obligations; oil and gas reserves; and Goodwill, as well as the write-off of certain balances, including unamortized debt issuance costs, RSU liabilities and prepaid or deferred amounts without future benefit to the Company, in connection with the application of the acquisition method of accounting and the preliminary purchase price allocation described in Note 1. Further, the adjustment reflects the cash settlement of Legacy Helix RSU and PSU awards for the portion of such settlement attributed to the purchase price and the establishment of accrued liabilities for special bonuses related to Legacy Helix executives.

 

(C)

Represents the pro forma adjustments to income tax related accounts on the balance sheet as a result of the Mergers. The net decrease in Deferred tax liabilities is primarily driven by the tax effect from the fair value adjustments resulting from the preliminary purchase price allocation discussed in Note (B). The tax impact of the transaction and compensation costs payable at closing are recorded to the tax receivables included in Other current assets.

 

(D)

Reflects the removal of the remaining unamortized deferred financing costs associated with Legacy Helix’s asset-based lending (“ABL”) Credit Facility, which is terminated in connection with the Mergers.

 

(E)

Represents the accrual of additional transaction costs directly attributable to the Mergers that are expected to be incurred by Legacy Hornbeck subsequent to June 30, 2026.

(1)

To remove the historical equity of Legacy Helix, the accounting acquiree, as a result of the reverse acquisition.

(2)

To record the accelerated vesting of Legacy Hornbeck’s stock-based compensation that was settled in shares as well as the recognition of incremental expense related to cash settlement RSUs held by non-employee directors.

(3)

To recognize the fair value of the preliminary purchase price consideration paid in the reverse acquisition of Legacy Helix. Refer to Note 1 for the components of the preliminary purchase price consideration.

Unaudited Pro Forma Condensed Combined Statements of Operations

(AA) Represents the elimination of Net revenues and Operating expense from the transactions between Legacy Hornbeck and Legacy Helix as if the entities had been consolidated affiliates.

(BB) Reflects the removal of amortization for dry docking costs and amortization of deferred mobilization costs associated with capitalizable balances as of January 1, 2025 as such costs were written off in connection with the application of the acquisition method of accounting and the preliminary purchase price allocation described in Note 1. Any remaining amortization relates solely to capitalizable costs incurred after January 1, 2025.

(CC) Reflects the increase in lease expense resulting from the application of preliminary purchase price accounting and alignment with accounting acquirer’s accounting policies.

(DD) Reflects the decrease to Depreciation expense based on the preliminary fair value adjustment and the estimated weighted average useful lives of the acquired Property, plant and equipment, net.

(EE) Reflects the recognition of employee compensation expense associated with cash-based retention and continuity awards granted in connection with the Mergers. The awards have an aggregate value of approximately $4.1 million and are subject to the occurrence of a service condition of two years after the grant date on May 18, 2026. For pro forma purposes, the associated compensation cost is recognized ratably over the requisite service period of two years, resulting in estimated compensation expense of $1.0 million and $2.0 million for the six months ended June 30, 2026 and the year ended December 31, 2025, respectively.

(FF) Reflects the accelerated vesting and settlement of RSUs, PSUs, Legacy Helix director restricted stock and certain option awards of Legacy Hornbeck in connection with the consummation of the Mergers.

(GG) Reflects (1) the removal of the historical amortization of deferred financing costs associated with Legacy Helix’s ABL Credit Facility, which is terminated in connection with the Mergers; (2) the removal of historical amortization of deferred financing costs related to the Legacy Helix’s MARAD debt and Senior Notes due 2029 which are assumed by the Company with remaining unamortized deferred financing costs written-off, in connection with the application of the acquisition method of accounting and the preliminary purchase price allocation described in Note 1; and (3) the amortization of the premium related to the MARAD debt and Senior Notes due 2029.

(HH) Represents the pro forma income tax effect of the adjustments related to the Mergers calculated by applying an estimated 26% overall global effective tax rate for the Company, adjusted for permanent non-deductible transaction and compensation differences, where applicable. Management believes this approach provides a reasonable basis for the pro forma income tax adjustments; however, the effective tax rate of the Company could be significantly different depending on the mix of activities. This preliminary estimate is subject to further assessment and adjustments as additional information becomes available.

 

Page 11 of 12


(II) Reflects the recognition of compensation expense associated with the settlement of long-term incentive programs at both Legacy Helix and Legacy Hornbeck, executive severance payments of Legacy Helix, as well as retention bonuses in connection with the Mergers.

(JJ) Represents the estimated transaction costs of $45.9 million to be incurred by Legacy Hornbeck subsequent to June 30, 2026, primarily consisting of investment banking, legal, and accounting advisory fees directly attributable to the Mergers. These transaction costs are nonrecurring and will not affect the Company’s statements of operations beyond twelve months after the closing of the Mergers. Transaction costs of $12.4 million are included in the historical statements of operations of Legacy Hornbeck for the six months ended June 30, 2026. Legacy Hornbeck incurred minimal transaction costs for the year ended December 31, 2025. Transaction costs of $8.3 million related to the Mergers are included in the historical statements of operations of Legacy Helix for the six months ended June 30, 2026. Legacy Helix did not incur transaction costs for the year ended December 31, 2025.

Earnings per Share

As the unaudited pro forma condensed combined statements of operations assumes that the Mergers had occurred on January 1, 2025, the beginning of the earliest period presented, the calculation of weighted average shares outstanding for basic and diluted earnings per share assumes that the shares issuable relating to the Mergers have been outstanding for the entirety of the periods presented. Diluted earnings per share assumes (i) converted options that remain eligible for exercise post-close remain outstanding and (ii) performance stock units are achieved at target.
