The Myth of the Pure-Play Shipping Company

Shipping companies are encouraged to remain simple, while being valued at a discount to the market value of their own vessels. But some nontraditional companies escape this paradoxical framework.

Shipping investors often say they prefer “pure-play” companies—simple fleets, single vessel classes, no distractions.

Yet the market almost never rewards those companies with valuations above their liquidation value.

The result is a paradox: shipping companies are encouraged to remain simple, while being valued at a discount to the market value of their own vessels.

Unlike most industries—where companies are valued on earnings—public shipping companies are valued on price-to-net-asset-value (P/NAV). In practice, this means investors focus less on what the business can earn and more on what its ships could be sold for.

That framework works when shipping companies are interchangeable owners of interchangeable assets operating in a highly competitive market. It begins to break down as companies differentiate themselves or embed more deeply into their customers’ supply chains.

The companies that escape this paradoxical framework will not look like traditional shipping companies—and that is precisely the point.

Navigator Gas (“Navigator”; NYSE: NVGS) is a useful example of what a more robust and value-add shipping company can look like in practice.

At first glance, Navigator resembles a conventional shipping company. It operates a fleet of 48 liquefied gas carriers, primarily transporting LPG and petrochemical gases. Through a pure-play lens, Navigator would be valued like its peers: ships in the water, earnings tied to freight rates, and a share price anchored to P/NAV.

But Navigator is not just a shipowner.

Navigator owns a 50% stake in the world’s largest ethylene export terminal in Texas, alongside U.S. energy infrastructure heavyweight Enterprise Products Partners (“Enterprise”; NYSE: EPD). Its investment places Navigator upstream in the petrochemical export chain, giving it exposure to infrastructure-like cash flows and privileged insight into the molecules its vessels are designed to move.

To understand why Navigator has made the strategic decision to take a stake upstream in this value chain—and why that matters for valuation—it helps to briefly understand the molecules it transports.

Plastic is everywhere. The device you are reading this on is likely encased in it.

Before becoming packaging, piping, or phone cases, plastics begin as molecules extracted from natural gas production—chiefly ethane. That ethane is “cracked” into ethylene, the world’s most widely produced organic chemical and the starting point for most plastic products.

The United States is the world’s largest producer of ethane and ethylene, a byproduct of the shale gas boom. Much of that production is exported to Asia, where it is further processed into finished plastics.

This trade requires specialized infrastructure (like Navigator & Enterprise’s jointly-owned export facility) and vessels (like those in the Navigator fleet) capable of safely handling one of the most technically demanding cargoes in the gas shipping market.

So what does this mean for Navigator’s valuation? Has the company escaped the gravitational pull of P/NAV?

Not quite.

The estimated P/NAV of Navigator’s fleet of vessels excluding the terminal investment is ~$21/share. The share price as of March 16, 2026 is ~$18/share.

Which means, an investor could buy Navigator’s stock today and get exposure to their fleet at a 15% discount to its market value and their 50% interest in the export terminal for free.

This begs the question as to what the stake in the export terminal could be worth and this requires utilizing one of the valuation metrics that we discussed earlier: EV/EBITDA.

Enterprise—Navigator’s co-owner of the export terminal—currently trades at an enterprise value of 10x their EBITDA (earnings before interest, taxes, depreciation, and amortization). The export terminal stands to generate $35 million of EBITDA for Navigator when fully utilized. Applying the 10x valuation metric, means NVGS’ stake in the terminal could be worth $350 million. If we add that on top of the NAV fleet that represents an incremental ~$5 per share.

If we add this to ~$21/share valuation of Navigator’s fleet of vessels, that brings a total valuation of ~$26/share.

Navigator Gas may not yet trade like an earnings business—but it is increasingly structured like one, and the company stands to be rewarded as investor valuation frameworks evolve beyond P/NAV.
