Third Quarter 2015 Results Summary

The Company recorded adjusted net income of $36.5 million or $0.45 basic and $0.44 diluted earnings per share for the three months ended September 30, 2015. This excludes the following: $1.5 million relating to stock-based compensation expense, $1.4 million relating to transaction-based professional fees unable to be capitalized, $0.1 million relating to loss on disposal of vessels and vessel equipment, $0.1 million related to the closing of the Company’s office in Portugal, and $0.1 million relating to non-cash G&A expenses other than stock-based compensation. The Company recorded an adjusted net loss of ($13.3) million or ($0.40) basic and diluted loss per share for the three months ended September 30, 2014. This excludes $0.2 million relating to stock-based compensation expense, $0.3 million relating to vessel impairment and loss on disposal of vessels and vessel equipment, $0.5 million related to the closing of the Company’s office in Portugal, and a gain of $0.1 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 September 30, 2015 was $33.2 million or $0.41 basic and $0.40 diluted earnings per share compared to a net loss of $(14.3) million or $(0.43) 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 with our operating and financial results for the third quarter of 2015, as we delivered a strong financial performance. During the quarter, we took delivery of our first “eco” VLCC vessel in our newbuilding program, the Gener8 Neptune, which entered the Navig8 VL8 Pool. In addition, as of November 1, 2015, we took delivery of both the Gener8 Strength and the Gener8 Athena, which also have entered the Navig8 VL8 Pool. We continue to deliver on our growth plan as stated during our IPO. With our modern, high quality fleet of crude tankers utilizing Navig8 Group’s strong commercial platform, we remain poised to drive future growth through multiple avenues.”

On July 17, 2015, following the exercise by the underwriters of the IPO of their over-allotment option to purchase 1,882,223 shares of common stock at the public offering price of $14.00 per share, the Company closed the issuance and sale of such shares, resulting in additional gross proceeds of $26.4 million and net proceeds of $24.6 million after underwriting commissions and other registration expenses.

Net Voyage Revenue increased by $47.0 million, or 147.8%, to $78.8 million for the three months ended September 30, 2015, compared to $31.8 million from the prior year period. The increase was primarily attributable to the increase in hire rates during the three months ended September 30, 2015 compared to the prior year period, as well as lower fuel prices during the period compared to the prior year period. Offsetting the increase in Net Voyage Revenue was a decrease in utilization to 92.5% for the three months ended September 30, 2015, compared to 95.6% for the prior year period. This decrease was primarily due to scheduled drydocking of two of our Suezmax vessels that were unexpectedly extended due to a typhoon that hit in the area of the shipyard.

The Company evaluates its performance using net voyage revenues. Net voyage revenues are voyage revenues minus voyage expenses. The Company believes that presenting voyage revenues, net of voyage expenses, neutralizes the variability created by unique costs associated with particular voyages or deployment of vessels on time charter, on the spot market, or through vessel pools and presents a more accurate representation of the revenues generated by its vessels.

Direct vessel operating expenses, which include crew costs, provisions, deck and engine stores, lubricating oil, insurance, maintenance and repairs decreased by $0.3 million, or 1.6%, to $20.5 million for the three months ended September 30, 2015 compared to $20.9 million for the prior year period.

General and administrative expenses increased by $3.2 million, to $8.2 million during the three months ended September 30, 2015 compared to the prior year period, primarily due to an increase in the compensation costs of restricted stock units of $1.5 million for the three months ended September 30, 2015 as compared to the prior year period. The restricted stock units were granted in connection with the pricing of our initial public offering and we recognized compensation expense upon the immediate vesting of a portion of the restricted stock units upon grant and the vesting of an additional portion upon the consummation of our initial public offering.

Adjusted EBITDA (which the Company calculated in accordance with the methodology set forth in the reconciliation tables below), for the three months ended September 30, 2015 increased by $42.2 million to $48.3 million compared to $6.1 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 $0.1 million, or 0.6%, to $11.6 million during the three months ended September 30, 2015 compared to $11.7 million for the prior year period.

Net interest expense decreased by $7.6 million, or 97.5%, to $0.2 million for the three months ended September 30, 2015 compared to $7.8 million for the prior year period. Such decrease was primarily attributable to the increase in the capitalization of interest expense associated with vessel construction of $9.2 million, to $12.4 million for the three months ended September 30, 2015 compared to $3.2 million for the prior year period as a result of the Company’s acquisition of the 14 VLCC newbuildings acquired in connection with the 2015 merger.

As of September 30, 2015, the Company’s cash balance was $244.6 million, compared to $147.3 million as of December 31, 2014.

As of September 30, 2015, the Company’s net debt (calculated as total debt less cash) was $546.1 million.

As of September 30, 2015, there were 82,105,376 shares of the Company’s common stock outstanding.

Nine Months Ended September 30, 2015 Results Summary

The Company recorded adjusted net income of $104.8 million or $1.86 basic and diluted earnings per share for the nine months ended September 30, 2015. This excludes the following: $11.6 million relating to stock-based compensation, $0.2 million relating to vessel impairment and loss on disposal of vessels and vessel equipment, $0.5 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, $1.0 million relating to non-cash G&A expenses other than stock-based compensation, and $1.3 million in transaction-based professional fees unable to be capitalized. The Company recorded an adjusted net loss of $(24.5) million or $(0.83) basic and diluted loss per share for the nine months ended September 30, 2014. This excludes the following: $1.2 million of goodwill impairment, $1.0 million

relating to stock-based compensation expense, $8.3 million relating to vessel impairment and loss on disposal of vessels and vessel equipment, $4.8 million related to the closing of the Company’s office in Portugal, and $0.4 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 due to increased rates and lower 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 nine months ended September 30, 2015 was $84.0 million or $1.50 basic and $1.49 diluted earnings per share compared to a net loss of $(40.1) million or $(1.36) basic and diluted loss per share for the prior year period.

Net Voyage Revenue increased by $122.5 million, or 109.8%, to $234.0 million for the nine months ended September 30, 2015 compared to $111.5 million for the prior year period. The increase was primarily attributable to the increase in hire rates during the nine months ended September 30, 2015 compared to the prior year period, as well as lower fuel prices for the nine months ended September 30, 2015 compared to the prior year period.

Direct vessel operating expenses decreased by $1.5 million, or 2.3%, to $62.6 million for the nine months ended September 30, 2015 compared to $64.1 million for the prior year period.

General and administrative expenses increased by $11.3 million, or 67.4%, to $28.1 million for the nine months ended September 30, 2015 compared to $16.8 million for the prior year period. The primary factors contributing to this increase were an increase in the compensation costs of restricted stock units of $10.4 million during the nine months ended September 30, 2015 compared to the prior year period.

Adjusted EBITDA (which the Company calculates in accordance with the methodology set forth in the reconciliation tables below), for the nine months ended September 30, 2015 increased $83.9 million to $116.0 million compared to $32.0 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 $0.7 million, or 2.1%, to $33.6 million during the nine months ended September 30, 2015 compared to $34.3 million for the prior year period. This decrease was primarily due to the change in our scrap rate to $325/ton from $265/ton, which more accurately reflects market prices.

Net interest expense decreased by $11.0 million, or 49.6%, to $11.1 million for the nine months ended September 30, 2015 compared to $22.1 million for the prior year period. Such decrease was primarily attributable to the increase in capitalization of interest expense associated with vessel construction of $18.3 million, or by 326.1%, to $23.9 million for the nine months ended September 30, 2015 compared to $5.6 million for the prior year period as a result of the Company’s acquisition of the 14 VLCC newbuildings in connection with the 2015 merger.

Other financing costs increased by $6.0 million, to $6.0 million during the nine months ended September 30, 2015 compared to $0 for the prior year period, 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, resulting in financing costs of approximately $6.0 million.

Leo Vrondissis, Chief Financial Officer, commented, “We continue to take advantage of what we believe to be a tightly balanced tanker market resulting in strong spot rates. We are excited to have closed over $1.6 billion in financing, encompassing a refinanced facility for our fleet on the water, a Korean ECA facility for the Korean newbuildings, and a bilateral loan for the first Chinese newbuilding. We look forward to utilizing our dynamic platform and balance sheet to grow our Company and maximize shareholder value in the future.”
