IMPP vs INSW: Which Is the Better Buy in 2026?
Last updated August 2026
Short answer
INSW is the larger of the two ($4.76B market cap): the incumbent the market prices for continued execution (15.45x forward earnings, beta -0.09). IMPP is the smaller challenger ($212.50M), cheaper on forward earnings (2.53x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.
IMPP vs INSW: the tie-breaker metrics
Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | IMPP | INSW | What it tells you |
|---|---|---|---|
| Market cap | $212.50M | $4.76B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 2.53 | 15.45 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Trailing P/E | 3.01 | 8.76 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Beta | 1.18 | -0.09 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 49% of range | 98% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 0.38 | 2.17 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Reading it: IMPP is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.
Before you buy: how IMPP and INSW affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. IMPP and INSW share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

What does Imperial Petroleum (IMPP) do?
Imperial Petroleum Inc. is a ship-owning company headquartered in Athens, Greece, that provides seaborne transportation of petroleum products, crude oil, and dry cargo. It was spun off from StealthGas in December 2021 and trades on the Nasdaq Capital Market, with its common stock under IMPP and an 8.75% Series A Cumulative Redeemable Perpetual Preferred under IMPPP. Its fleet mixes MR product tankers, a suezmax, and handysize, supramax and kamsarmax drybulk carriers, and management has been growing the fleet toward roughly 26 vessels on the water in 2026 with additional deliveries agreed. Because much of the fleet operates in the spot market, revenue and profit track daily charter rates closely, which makes results swing sharply quarter to quarter with the strength of tanker and drybulk markets.
What does International Seaways (INSW) do?
International Seaways owns and operates a fleet of roughly 70 oceangoing vessels that transport crude oil and refined petroleum products in international trade. The business runs across two segments, Crude Tankers (VLCCs, Suezmaxes, and Aframaxes) and Product Carriers (MRs, LR1s, and LR2s), and also provides ship-to-ship lightering support services. Revenue is driven almost entirely by daily spot charter rates, which swing sharply with global oil demand, ton-mile trade patterns, and geopolitical disruption.
IMPP vs INSW: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- IMPP drivers: Debt-free balance sheet and asset backing; Fleet growth into a strong shipping cycle.
- INSW drivers: Strong tanker spot rates; Diversified fleet mix.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: The dominant risk is charter-rate cyclicality: with heavy spot exposure, Imperial's profits can fall as fast as they rose if tanker or drybulk rates weaken, so recent record quarters should not be extrapolated. For INSW, iNSW's earnings are highly cyclical and depend on spot charter rates that can fall sharply and unpredictably.
IMPP or INSW: which should you pick?
Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick IMPP if you believe its drivers more; INSW if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the IMPP and INSW guides.
IMPP vs INSW: the full fundamentals
IMPP. All figures are approximate, tied to the asOf date, and should be verified against the latest company filings before acting. As a foreign private issuer, Imperial reports on Form 6-K and 20-F, so the cadence and format differ from US domestic filers. For a spot-exposed shipping company, trailing earnings reflect where charter rates recently sat in the cycle and may not repeat, so the durability of cash flows and the pace of capital returns matter more than any point-in-time P/E. The recurring question for this stock is whether management narrows the gap to asset value through buybacks and returns, or issues more equity and widens it again.
INSW. INSW posted record Q1 2026 results, with revenue up roughly 78% year over year and adjusted EPS of about $3.90 beating consensus. Tanker operators typically trade at low single-digit to high single-digit forward earnings multiples to reflect the cyclicality of spot rates. Reported earnings can swing widely quarter to quarter with the rate environment.
Headline figures (approximate, Jul 2026): IMPP shows revenue trend Grew year over year in 2025 (reported around the low $160 millions), with 2026 quarters described by the company as among its best ever; figures are approximate, verify live, profitability Solidly profitable through the strong 2024-2026 tanker cycle, with meaningful net income and EBITDA; earnings are highly sensitive to charter rates and can swing sharply, balance sheet Debt-free with a large cash and time-deposit position (reported around the high $100 millions at year-end 2025); unusually strong for a company this size, verify current figures, market cap tier Micro-cap; the equity value has at times sat below reported cash plus fleet value, the basis of the deep-value thesis; INSW shows revenue (q1 2026) ~$325M, revenue (fy2025) ~$1.0B, net income (q1 2026) ~$286M, diluted eps (fy2025) ~$6.23.

FAQ
What is the difference between IMPP and INSW?
+
Imperial Petroleum Inc. International Seaways owns and operates a fleet of roughly 70 oceangoing vessels that transport crude oil and refined petroleum products in international trade. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is IMPP or INSW the better stock?
+
Neither is universally better. INSW is the larger incumbent; IMPP is the smaller challenger and looks cheaper on forward earnings. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, IMPP or INSW?
+
On forward P/E (as of August 2026), IMPP trades at 2.53x and INSW at 15.45x, so IMPP is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both IMPP and INSW?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of IMPP vs INSW?
+
IMPP: The dominant risk is charter-rate cyclicality: with heavy spot exposure, Imperial's profits can fall as fast as they rose if tanker or drybulk rates weaken, so recent record quarters should not be extrapolated. Dilution is the other defining risk. The company has repeatedly raised equity and issued warrants to fund fleet growth, sharply increasing the share count in the past, and the market prices in the possibility that it does so again, which is a big reason the stock trades below net asset value. As a Marshall Islands foreign private issuer that reports on Form 6-K/20-F rather than standard domestic filings, disclosure cadence differs from US companies. Vessel values, fuel costs, geopolitical disruption to trade routes, and concentration in a small fleet all add volatility. Finally, being a low-priced micro-cap, the shares can be thinly traded and prone to sharp swings. INSW: INSW's earnings are highly cyclical and depend on spot charter rates that can fall sharply and unpredictably. A downturn in oil demand, a wave of newbuild vessel deliveries, or a normalization of trade routes could compress rates and cut cash flow quickly. The variable dividend can shrink dramatically in weak quarters because most of the payout is supplemental rather than base. Geopolitical shocks cut both ways, boosting rates in some scenarios and disrupting operations in others. Long-term demand for seaborne oil transport also faces uncertainty from the energy transition.
