Disclaimer Forward - Looking Statements During the course of this presentation, the Company (International Seaways, Inc. (INSW)) may make forward - looking statements or provide forward - looking information. All statements other than statements of historical facts should be considered forward - looking state ments. Some of these statements include words such as ‘‘outlook,’’ ‘‘believe,’’ ‘‘expect,’’ ‘‘potential,’’ ‘‘continue,’’ ‘‘may,’’ ‘‘will,’’ ‘‘s hould,’’ ‘‘could,’’ ‘‘seek,’’ ‘‘predict,’’ ‘‘intend,’’ ‘‘plan,’’ ‘‘estimate,’’ ‘‘anticipate,’’ ‘‘target,’’ ‘‘project,’’ ‘‘forecast,’’ ‘‘shall,’’ ‘‘contemplate’’ or the neg ative version of those words or other comparable words. Although they reflect INSW’s current expectations, these statements are not guarantees of future performan ce, but involve a number of risks, uncertainties, and assumptions which are difficult to predict. Some of the factors that may cause actual out com es and results to differ materially from those expressed in, or implied by, the forward - looking statements include, but are not necessarily limite d to, vessel acquisitions, general economic conditions, competitive pressures, the nature of the Company’s services and their price moveme nts , and the ability to retain key employees. The Company does not undertake to update any forward - looking statements as a result of future developme nts, new information or otherwise. Non - GAAP Financial Measures Included in this presentation are certain non - GAAP financial measures, including Time Charter Equivalent (“TCE”) revenue, EBITDA , Adjusted EBITDA, and total leverage ratios, designed to complement the financial information presented in accordance with generally ac cep ted accounting principles in the United States of America because management believes such measures are useful to investors. TCE revenues, w hic h represents shipping revenues less voyage expenses, is a measure to compare revenue generated from a voyage charter to revenue generated fro m a time charter. EBITDA represents net (loss)/income before interest expense, income taxes and depreciation and amortization expense. Ad justed EBITDA consists of EBITDA adjusted for the impact of certain items that we do not consider indicative of our ongoing operating perfo rma nce. Total leverage ratios are calculated as total debt divided by Adjusted EBITDA. We present non - GAAP measures when we believe that the additional information is useful and meaningful to investors. Non - GAAP financial measures do not have any standardized meaning and are therefore unlikely to be comparable to similar measures presented by other companies. The presentation of non - GAAP financial measures is not intended to be a substitute for, and should not be considered in isolation from, the financial measures reported in accordance with GAAP. See Appendix fo r a reconciliation of certain non - GAAP measures to the comparable GAAP measures. This presentation also contains estimates and other information concerning our industry that are based on industry publicatio ns, surveys and forecasts. This information involves a number of assumptions and limitations, and we have not independently verified the accu rac y or completeness of the information.

Market Update – Oil Supply, Demand and Implications • Oil Supply and Demand o IEA’s November forecast expects 2020 Q4 demand to be at 94.9 million b/d, down from 96.1 million b/d, and expects demand to be at 99.1 million b/d by end of next year o IEA expects stock drawdowns which are needed to set the stage for tanker recovery o On supply side, OPEC’s current intention of adding 2 million b/d supply in Q1 should increase tanker demand, although extension of cuts also being discussed o IEA expects diesel and gasoline demand to be at 98% of 2019 levels by the end of the year Source: IEA 7

Market Update – Ship Supply • Orderbook Update o Orderbook remains at historical lows: • VLCC 7.7% • Suezmax 9.7% • Aframax/LR2 10.1% • Panamax/LR1 1.8% • MR 6.4% o 31 VLCCs ordered in 2019; 2020 saw only 16 orders through September, although an additional 14 orders are believed to be firm o Ordering tempered by uncertainty surrounding markets, decarbonization, and suitable propulsion systems • Recycling potential o The VLCC fleet is aging – 210 ships out of a fleet of 828 will be 15 years old or older by year end o A further 22 VLCCs will reach age 20 during 2021 o At age 15 and every 2.5 years thereafter significant investment required to continue to trade o As ships reach ballast water treatment deadlines, even greater capital expenditure is required to keep trading o After a record 31 ships recycled in 2018, only four VLCCs were recycled in 2019 and none YTD 2020.

INSW Metrics Based on Clarksons Estimates • The view from the tanker bridge is somewhat foggy – Research views on remainder of 2020 and full year 2021 rates vary widely, given differing views on the pace, extent and effect of the global oil and refined product de - stocking period. • To assist analysts and potential investors with modeling and valuation assessment, we provide estimates of key INSW earnings metrics for 2021 from host Clarksons. 14

Industry Leading ESG Footprint • Environmental o Commitment to minimizing risk of all forms of pollution o Sustainability - linked pricing feature of INSW’s new debt facility o Active compliance programs for IMO 2020, ballast water treatment o CEO on the board of ITOPF o NAMEPA Marine Environment Protection award, 2019 • Social o International Seaways meets, and when possible, exceeds compliance with all applicable rules and regulations governing the maritime industry o Safe, healthy and secure working conditions for all employees on land and at sea o Member of the Marine Anti - Corruption Network • Governance o Six of eight members of Board of Directors fully independent o Split non - Executive Chairman and CEO o Commitment to diversity exemplified by two female directors (including CEO) o Webber Research / Wells Fargo ESG Ranking: o #1 among tanker shipping companies o #2 of 56 shipping companies overall o Three years in a row: 2018, 2019, 2020 16

Transparency in CO 2 Emissions Reporting • In 2018, the IMO adopted an initial strategy for reducing greenhouse gas (“GHG”) emissions from vessels, and calling for a 70% reduction in carbon emissions from 2008 levels by 2050 o IMO established trajectories and targets for each ship type and size, considering their emissions, trading patterns, and othe r factors • INSW currently reports total CO2 produced and its Annual Efficiency Ratio as part of its efforts to help the shipping industry move forward towards a low - carbon future • INSW has also contractually committed in its credit facility to reporting its annual achievement against the IMO GHG target trajectories on a fleet - wide basis • For 2019, International Seaways’ fleet achieved a Poseidon Principles Fleet Sustainability Score of 1.06, indicating that, for 2019, the carbon emissions for the fleet was 6% over the IMO trajectories for the year (on a deadweight ton average basis) 17 Vessel Data Fuel Use and CO 2 Emissions Data Fleet Annual Emissions Rate (AER) 1 # of Vessels in Fleet Jan. 1, 2019: 38 HFO Consumed: 324,723 MT 3.56 # of Vessels in Fleet Dec. 31, 2019: 36 LSFO Consumed: 3,039 MT # of Vessel Days: 13,486 Gas Oil Consumed: 53,807 MT Distance travelled: 2,117,087 NM CO 2 Produced: 1,193,271 MT

We Will Achieve Decarbonization Using the Technology of Today … • “Get To Green” Initiative o Working in conjunction with our third - party technical managers, in 2018 we initiated a “Get to Green” initiative, where we encourage our crews to continually monitor and report equipment performance metrics in order to improve our vessel efficiencies. o We have seen significant improvements as a result – for example, between October 2018 and September 2019, our fleet’s propulsion efficiency improved 5.8%, meaning that we reduced fuel consumption by 8,500 MT, or approximately 26,500 MT of CO2 o This propulsion efficiency metric is one of our Key Performance Indicators, which is reported to our Board and is used as a criteria in calculating annual employee bonuses • Fleet Renewal o Upgrading our fleet has improved our emissions profile, because newer vessels (like our six new VLCCs (5x2016, 1x2015) and our two new Suezmax (2018) are ECO efficient and more environmentally sound o Efforts around the biggest vessels offer the biggest opportunities for improvements • Other initiatives under evaluation: o Technical Efficiencies • Better hull paints • Improvement devices (e.g. Mewis ducts) • More efficient hull cleanings o Commercial Efficiencies • Less idle time • Fewer slack tanks • Slower steaming 18
