Memo

TSAKOS ENERGY NAVIGATION LIMITED (TEN). Latest full fiscal year: 2025; data up to 2025-12-31.

Figures computed from the financial statements: revenue 798.7 m USD in 2025; YoY growth -0.7%; net margin 20.1%; ROE 9.1%; net debt/EBITDA 3.5x.

The estimated value range is 14.23–89.24 USD per share (median of 2 methods, agreement: same basis (multiples on one peer group, not independent confirmations)); assumptions are illustrative. Against the central value of 46.49 USD, the price of 44.10 USD leaves a potential of 5.4% (value / price − 1) and a margin of safety of 5.1% (1 − price / value). The range is the median of the methods' low, central and high values, not a probability interval.

olivLaw score 32/100, methodological classification: unattractive profile (score, margin of safety and method agreement together; not a judgement of the right price). Groups assessed only in part: returns. Not investment advice.

Text generated deterministically from the figures shown; no language model. Not investment advice.

What supports the thesis

No signal among the computed factors. That is not an absence of risk: factors without data were not assessed, and business risks (margins, inventory, demand) are in the source-based analysis.

What contradicts it

  • ROIC: 6.6%
  • Revenue CAGR 3Y: -2.5%
  • EPS CAGR 3Y: -9.5%
  • Net debt / EBITDA: 3.5x
  • Interest coverage: 2.7x
  • Current ratio: 0.9x

Not assessed (insufficient data or a ratio without meaning): FCF conversion, FCF yield, Payout ratio (FCF).

AI-generatedAI-generated analysis (Claude) from cited public sources; it may contain errors. Not investment advice. As of 27 Oct 2026 · Model: claude-haiku-5-5.

Possibly outdated: the newest document it read is from 06 Apr 2026; since then the company filed 6-K (17 Sept 2026), 6-K (22 May 2026), 6-K (17 Apr 2026).

In brief

Tsakos Energy Navigation is an international operator of tankers for seaborne transport of crude oil, petroleum products and LNG, with a fleet of 64 vessels in operation at the end of March 2026 1. The company operates in a period when geopolitical tensions and rerouting of trade flows support demand for ships, and its fleet has a large share of long-term contracts.

SWOT

Strengths

  • A relatively modern, diversified fleet with long-term contracts for much of it.
  • Long relationships with major oil companies and refiners that support high utilization.
  • Technical management delegated to an entity holding quality and environmental certifications.

Weaknesses

  • Dependence on a relatively small number of ships, where each unit weighs heavily on results.
  • A management structure through affiliated entities may raise governance questions for investors.
  • Rising operating costs reduced margins in fiscal 2025.

Opportunities

  • Long-term contracts for DP2 shuttle tankers could expand the offshore segment.
  • A limited orderbook could support vessel values and rates over the medium term.
  • Demand for LNG transport could grow if use of this fuel expands.

Threats

  • Falling oil demand, if geopolitical tensions cause demand destruction, could reduce rates.
  • Environmental rules and the energy transition could lower the value of older ships over the long term.
  • New ships entering the fleet could reduce rates if the orderbook grows.

Risks

  • Tanker rate volatilityhigh

    Revenues depend on a competitive charter market that can fall quickly if demand shifts.

  • Geopolitical riskshigh

    Conflicts and closures of sea routes can abruptly change transport flows and costs.

  • Debt and financing costsmedium

    Financing new ships involves debt, and changes in interest rates can affect profitability.

  • Operating and maintenance costsmedium

    Rising operating costs and dry-docking work can reduce operating margins.

  • Environmental regulationlow

    Stricter rules on emissions and fuels could require additional ship investment.

Investment thesis

What would need to be true (bull case)

  • If geopolitical tensions and rerouting of trade persist, spot rates could stay high and the fleet could generate higher revenues.
  • A limited orderbook and a relatively new fleet could support vessel values over the medium term.
  • Long-term contracts for DP2 shuttle tankers could provide more predictable revenues in the coming years.

What would break the thesis

  • If oil demand falls because of high prices, tanker rates could quickly return to lower levels.
  • The energy transition could reduce long-term demand, especially for older vessels.
  • High debt and rising costs could limit the company's capacity to pay dividends.

The business

The company provides international seaborne transport of crude oil and petroleum products and, since 2007, of liquefied natural gas 1. The operating fleet includes VLCC, suezmax, aframax, panamax, handysize, MR tankers, LNG carriers and DP2 shuttle tankers for offshore operations 1. Technical and operational management is subcontracted to Tsakos Shipping and Trading S.A., based in Athens 1.

The company has built a reputation as a safe and cost-efficient operator with modern ships and an average fleet age below the industry average 1. Customers include major oil companies, refiners and traders, among them Equinor, BP, Exxonmobil, Shell and Vitol 1. The share of ships on fixed-rate charters makes revenues more predictable, but limits gains from rising spot rates.

A Bermuda company listed in New York under the symbol TEN since July 1, 2024, it reports annual and quarterly results in filings with regulators 1. For fiscal 2025, voyage revenues were 798.7 mn USD and net income attributable to the company was 160.9 mn USD 1.

Segments

Conventional crude and product tankers

The VLCC, suezmax, aframax and panamax fleet carries crude oil and products, especially on long-haul routes 1. In 2025, revenues in this segment were shaped by market rates, which fell slightly from the prior year 1.

DP2 shuttle tankers for offshore

Six DP2 suezmax shuttle tankers are in operation, and ten more are under construction with long-term contracts on delivery 1. The company regards this segment as a strategic advantage because it links offshore installations to onshore terminals 1.

LNG transport

The company operates two LNG carriers, and a third is under construction with planned delivery in 2028 1. The LNG segment is smaller in the fleet but diversifies exposure away from the oil market 1.

Market context

Global oil demand reached a record level in 2025, and the International Energy Agency expects a rise for 2026, provided Middle East tensions do not strongly affect demand 1. The tanker orderbook is a relatively small share of the existing fleet, which could limit supply growth over the next two to three years 1.

The market is cyclical and sensitive to sanctions, route disruptions and vessel availability, factors that can change spot rates and asset values 1. The company believes that if these conditions persist, they could support a healthy tanker market 1.

Trends

  • Reorientation of trade flowstailwind

    Sanctions on Russian oil have led to longer routes, which increases demand for ships and supports rates 1. The effect could fade if trade flows stabilize.

  • Middle East disruptionsmixed

    Attacks on ships and closures of routes led to rerouting around the Cape of Good Hope and longer distances 1. If tensions persist, spot rates could stay high, but the risk of demand destruction rises.

  • Limited tanker orderbooktailwind

    The tanker orderbook is relatively small against the existing fleet, and shipyard capacity is limited until 2028 1. This factor could limit supply growth and support vessel values.

  • Ageing global fleet and energy transitionmixed

    Part of the global fleet is old, and discussions on alternative fuels could change future vessel designs 1. The energy transition could reduce long-term demand, although the company expects oil and LNG to remain important for longer than previously thought 1.

Competitive position

The company competes in the global tanker market with other public and private operators, and charter rates are set in a highly competitive environment 1. The advantages the company cites are its younger fleet, the diversity of vessel types and long-standing customer relationships 1.

  • US-listed tanker operators

    The source does not name competitors, so no ticker can be reliably given.

  • Private tanker operators

    Competition also comes from private fleets operating on similar routes that may offer competitive rates.

  • Shadow fleet of sanctioned vessels

    Ships carrying sanctioned oil compete indirectly by shaping the routes and rates available to others.

  • LNG carrier operators

    In the LNG segment, competition comes from specialized operators that manage larger fleets.
