This excludes the following: $9.8 million relating to stock-based compensation expense, $0.02 million relating to vessel impairment and loss on disposal of vessels and vessel equipment, $0.2 million related to the closing of the Company’s office in Portugal, $6.0 million in one-time financing costs primarily due to the issuance of common shares as a commitment premium pursuant to a commitment agreement for the purchase and sale of common shares entered into in connection with the merger with Navig8 Crude Tankers and the subsequent termination of such agreement upon the IPO, and $1.0 million relating to non-cash G&A expenses other than stock-based compensation. The Company recorded an adjusted net loss of ($19.9) million or ($0.63) basic and ($0.63) diluted loss per share for the three months ended June 30, 2014. This excludes $1.2 million of goodwill impairment, $0.4 million relating to stock-based compensation expense, $6.9 million relating to vessel impairment and loss on disposal of vessels and vessel equipment, $4.2 million related to the closing of the Company’s office in Portugal, and $0.6 million relating to non-cash G&A expenses other than stock-based compensation. The increase in adjusted net income was primarily due to an increase in the Company’s net voyage revenue, which are voyage revenues minus voyage expenses, resulting from an increase in rates and a decrease in fuel costs compared to the prior year period.  Please see below for a reconciliation of net income / (loss) to adjusted net income / (loss).

Net income for the three months ended June 30, 2015 was $19.9 million or $0.38 basic and diluted earnings per share compared to a net loss of $(33.3) million or $(1.05) basic and diluted loss per share for the prior year period.

Peter Georgiopoulos, Chairman and Chief Executive Officer of Gener8 Maritime, commented, “We are pleased to report solid operating and financial results for Gener8 Maritime’s first quarterly earnings release post-IPO. The second quarter and July 2015 was an extremely exciting time for the Company as we closed the merger between General Maritime and Navig8 to create Gener8 Maritime, consummated a successful public offering resulting in $236 million of gross proceeds, and moved forward in executing our strategic plan to further our position as one of the leading international seaborne crude oil transportation service companies in the world. We are already benefiting from our strategic merger and our relationship with Navig8 Group, having delivered 14 vessels into the Navig8 pools. We expect to receive delivery of our first eco VLCC in September 2015 and are on schedule with our remaining newbuilding program. Upon completion of our newbuilding program, we believe that Gener8 Maritime’s VLCC fleet will be one of the largest in the industry based on current estimated fleet sizes. With our modern, high

quality fleet of crude tankers utilizing Navig8 Group’s strong commercial platform, we are poised to drive future growth through multiple avenues.”

Voyage revenues increased by $33.2 million, or 39.8%, to $116.5 million for the three months ended June 30, 2015 compared to $83.3 million for the three months ended June 30, 2014. The increase in voyage revenues was primarily attributable to the increase in the Company’s spot market revenues by $25.4 million, or 31.4%, to $106.3 million for the three months ended June 30, 2015 compared to $80.9 million for the prior year period. The increase in spot market revenues was driven by the increase in the Company’s spot market hire rate compared to the prior year period. Also contributing to the increase in voyage revenues was an increase in the Company’s time charter revenues by $7.8 million compared to the prior year period primarily due to an increase in charter hire rates as well as the voyage revenues associated with the time chartered-in vessel obtained in connection with the merger with Navig8 Crude, which generated gross revenue of $2.8 million during the period from May 7, 2015 (merger closing date) to June 30, 2015.

Voyage expenses decreased by $21.2 million, or 36.6%, to $36.8 million for the three months ended June 30, 2015 compared to $58.0 million for the prior year period. Substantially all of the Company’s voyage expenses relate to spot charter voyages, under which the vessel owner is responsible for voyage expenses such as fuel and port costs. The decrease in the voyage expenses during the three months ended June 30, 2015 compared to the prior year period was primarily due to the decrease in fuel costs.

Direct vessel operating expenses, which include crew costs, provisions, deck and engine stores, lubricating oil, insurance, maintenance and repairs decreased by $0.2 million, or 0.9%, to $21.1 million for the three months ended June 30, 2015 compared to $21.3 million for the prior year period.

General and administrative expenses increased by $9.0 million, to $15.3 million during the three months ended June 30, 2015 compared to the prior year period, primarily due to an increase of $8.9 million in non-cash compensation associated with the granting of restricted stock units (“RSUs”) in connection with the Company’s IPO.

Adjusted EBITDA (which the Company calculated in accordance with the methodology set forth in the reconciliation tables below), for the three months ended June 30, 2015 increased by $52.9 million to $51.5 million compared to a loss of ($1.4) million for the prior year period. Please see below for a reconciliation of net income / (loss) to adjusted EBITDA.

Depreciation and amortization expenses decreased by $0.5 million, or 4.3%, to $11.0 million during the three months ended June 30, 2015 compared to $11.5 million for the prior year period.

Net interest expense decreased by $3.5 million, or 49.9%, to $3.5 million for the three months ended June 30, 2015 compared to $7.0 million for the prior year period. Such decrease was primarily attributable to an increase in the amount of capitalized interest that the Company recorded in the three months ended June 30, 2015 due to the additional 14 VLCC’s under construction owned by the Company following the merger with Navig8 Crude Tankers Inc.

Other financing costs increased by $6.0 million, to $6.0 million during the three months ended June 30, 2015 compared to $0 for the prior year period, due to the issuance of common shares as a commitment premium pursuant to a commitment agreement for the purchase and sale of common shares entered into in connection with the merger with Navig8 Crude Tankers and the subsequent termination of such agreement upon the IPO, resulting in financing costs of approximately $6.0 million.

As of June 30, 2015, the Company’s cash balance was $356.9 million, compared to $147.3 million as of December 31, 2014.

As of June 30, 2015, the Company’s net debt (calculated as total debt less cash) was $441.9 million.

As of June 30, 2015, there were 79,990,334 shares of the Company’s common stock outstanding.

We look forward to utilizing our dynamic platform and balance sheet to grow our Company and maximize shareholder value.”

Gener8 Fleet

As of July 31, 2015, Gener8 Maritime’s fleet was comprised of 47 tankers, including one time chartered-in VLCC and 46 owned vessels comprised of 25 vessels on the water, consisting of 7 VLCC’s 11 Suezmax vessels, 4 Aframax vessels, 2 Panamax vessels and 1 Handymax product carrier, with an aggregate carrying capacity of 4.8 million deadweight tons (“DWT”), and 21 “eco” VLCC newbuildings with expected deliveries from September 2015 through February 2017. These newbuildings are expected to more than double the Company’s owned fleet capacity to 10.8 million DWT, based on the contractually-guaranteed minimum DWT of newbuild vessels. As of July 31, 2015, six of the Company’s VLCC vessels (including a time chartered-in vessel) were deployed in Navig8 Group’s VL8 Pool, four of the Company’s Suezmax vessels were deployed in Navig8 Group’s Suez8 pool and all four of the Company’s Aframax vessels were deployed in the Navig8 Group’s V8 Pool.

The Company expects to deliver five of its remaining Suezmax vessels to the Suez8 pool in August 2015, an additional two Suezmax vessels to the Suez8 Pool in September 2015 (after they complete scheduled drydocking), and each of the newbuilding VLCC’s into the VL8 Pool as they deliver.

The vessels TCE earnings are outlined the chart below:

The average daily spot TCE rates obtained by the Company’s VLCC fleet was $40,900 for the three months ended June 30, 2015 and $42,677 for the six months ended June 30, 2015. During the three months ended June 30, 2015, the Company completed its planned reduction in the number of third-party technical managers utilized by the Company. As is customary in connection with technical manager transitions, the Company was required to reestablish previously obtained vetting approvals for 5 of its 6 spot VLCCs, and took voyages for these vessels at unfavorable rates during this process. These voyages allowed the Company to obtain new approvals after the completion of the required SIRE discharge inspection under the new technical manager. Excluding these voyages, our spot VLCC fleet would have earned an average daily spot TCE rate of $58,691 for the three months ended June 30, 2015 and $49,456 for the six months ended June 30, 2015.

During the three months ended June 30, 2015, we had three vessels on time charter contracts, two VLCCs and one Suezmax, as outlined in the Fleet Profile table below.
