Is It Too Late To Consider International Seaways After Its 350% Five Year Surge?

  • If you are wondering whether International Seaways is still a smart buy after its big multiyear run, or if most of the upside is already priced in, this article will walk through whether the current share price looks compelling or stretched.
  • Even after a recent pullback of 5.0% over the last week and 10.1% over the past month, the stock is still up 33.9% year to date and 49.0% over the last year, with a 350.1% gain over five years that naturally raises questions about future returns and risk.
  • Those moves sit against a backdrop of tight global tanker capacity, elevated crude and product trade flows, and shipping markets that continue to benefit from reshaped trade routes, especially as Russian oil and refined products are redirected and longer haul voyages support strong day rates. In addition, industry wide commentary has highlighted robust charter markets and disciplined fleet growth, giving investors a structural story to match the recent price action.
  • Right now, International Seaways scores a 4 out of 6 on our valuation checks. You can explore this in more detail via our valuation score. Next we will unpack what different valuation approaches say about that number, before closing with a more practical way to think about what this stock may be worth.

International Seaways delivered 49.0% returns over the last year. See how this stacks up to the rest of the Oil and Gas industry.

Approach 1: International Seaways Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model estimates what a business is worth by projecting its future cash flows and discounting them back to today using a required rate of return. For International Seaways, the model starts with last twelve month Free Cash Flow of about $143 Million and then projects how that cash flow might evolve over time.

Analysts directly forecast Free Cash Flow of roughly $277 Million in 2026, and Simply Wall St extrapolates beyond that, with projected annual FCF staying in a similar $250 Million to $285 Million range over the following decade. These future cash flows are then discounted to reflect risk and the time value of money, using a 2 Stage Free Cash Flow to Equity framework.

On this basis, the DCF model arrives at an estimated intrinsic value of about $120.19 per share. That implies the stock is trading at roughly a 59.6% discount to this estimated fair value, which indicates the market may be pricing in much weaker long term cash flows or higher risk than the model assumes.

Result: UNDERVALUED (based on this DCF model)

Our Discounted Cash Flow (DCF) analysis suggests International Seaways is undervalued by 59.6%. Track this in your watchlist or portfolio, or discover 908 more undervalued stocks based on cash flows.

Approach 2: International Seaways Price vs Earnings

For profitable companies like International Seaways, the Price to Earnings (PE) ratio is a practical way to judge valuation because it links what investors pay today to the profits the business is generating right now. In broad terms, faster and more reliable earnings growth, as well as lower perceived risk, usually justify a higher PE ratio, while cyclical or riskier earnings tend to warrant a lower one.

International Seaways currently trades on a PE of about 11.0x. That is slightly above the tanker peer average of roughly 9.8x, but below the wider Oil and Gas industry average of around 13.3x. This comparison suggests the stock is not obviously expensive within its broader sector. To refine this view, Simply Wall St uses a proprietary Fair Ratio of 13.0x, which estimates the PE the company should trade on after adjusting for its earnings growth outlook, profitability, risk profile, industry positioning and market capitalization.

This Fair Ratio is more informative than a simple peer or industry comparison because it explicitly incorporates company specific fundamentals rather than assuming all firms deserve similar multiples. Since the Fair Ratio of 13.0x is higher than the current 11.0x, the PE based lens points to International Seaways being undervalued on earnings.

Result: UNDERVALUED

Upgrade Your Decision Making: Choose your International Seaways Narrative

Earlier we mentioned that there is an even better way to understand valuation. Let us introduce you to Narratives, a simple framework on Simply Wall St's Community page where you connect your view of a company’s story to your own forecast for its future revenue, earnings and margins. This then links to a Fair Value that you can compare with today’s share price to help decide whether to buy, hold or sell. That Fair Value automatically updates as new news or earnings arrive so your view never goes stale. For International Seaways, for example, one investor might build a bullish narrative around tightening vessel supply, modern fleet upgrades and resilient dividend support that justifies a Fair Value closer to the high analyst target of about $64. Another may stress long term decarbonization risks, volatile spot exposure and regulatory costs and land nearer the low target around $47. Narratives makes these differing perspectives transparent, quantified and easy to track over time.
