International Seaways (INSW) Stock May Be 40% Below Fair Value On Cash Flow

Simply Wall St·08/15/2026 23:27:13
Listen to the news

International Seaways has delivered a very large 5 year return, yet its valuation picture is more measured, with the Discounted Cash Flow (DCF) intrinsic value estimate pointing to a sizeable discount while standard multiples look closer to fair.

  • International Seaways has returned about 9x over the past 5 years, which puts extra focus on whether the current price still leaves room for further upside.
  • Future cash flow generation from its fleet and capital allocation decisions can support the current valuation, while any sustained pressure on shipping rates or operating costs may weigh on what investors are willing to pay.
  • The stock earns a mixed valuation profile with a 4 out of 6 value score, which points to a company that screens undervalued on some checks but not as a straightforward bargain across the board.

The issue now is whether International Seaways' strong share price performance and intrinsic value estimate still justify taking valuation risk at current levels.

International Seaways delivered 162.9% returns over the last year. See how this stacks up to the rest of the Oil and Gas industry.

Is International Seaways Still Cheap on Cash Flow?

The Discounted Cash Flow (DCF) model looks at the cash International Seaways can generate for shareholders over time. International Seaways produced about $320.9 million in free cash flow over the last twelve months, and the DCF framework assumes that this cash flow profile gently adjusts rather than relying on very aggressive long term growth.

On these assumptions, the DCF model points to an intrinsic value of about $161 per share, which is around 39.8% above where the stock is currently trading. Even though free cash flow projections are relatively steady, this gap between the estimate and the market price indicates that investors may not be fully pricing in the cash that the current fleet and capital plans are expected to generate.

On balance, the DCF analysis suggests that International Seaways stock currently appears undervalued on this basis.

Where Does International Seaways Sit on Earnings?

The P/E ratio is a useful way to see what investors are paying for each dollar of International Seaways earnings today. It links directly to the bottom line that ultimately funds dividends, buybacks and reinvestment.

International Seaways currently trades on a P/E of about 6.2x. That is well below the wider oil and gas industry average of roughly 12.5x and also below the peer group average of about 16.6x. A tailored fair P/E ratio for the company sits close to 5.7x, which reflects its sector, profitability profile and risks, and is only slightly under the present market multiple.

The gap between the current 6.2x and the modelled fair 5.7x is relatively small. This points to a stock that no longer screens as an obvious bargain on earnings alone, even if it still trades at a discount to some peers.

Overall, International Seaways appears to be trading at roughly fair value based on its P/E multiple.

The Bottom Line

For International Seaways, the Discounted Cash Flow (DCF) work still points to meaningful intrinsic value upside, while the P/E view now sits closer to about right. That mix is consistent with a stock that no longer looks like a clear-cut bargain but still carries a valuation gap if cash flows materialise as modelled. The crux for investors is whether shipping markets and the company’s capital decisions keep free cash flow resilient enough to justify that intrinsic value estimate, or whether the current multiple shows that the market is already correctly pricing in future volatility.
