Maritime M&A: The Hidden Liabilities That Can Sink Deal Value

Deferred maintenance on vessels and waterfront infrastructure can function as hidden transaction debt — an obligation that never appears in the purchase price but lands squarely on the buyer after closing. That is the core warning from Sabrina Brigance, managing director of Hylant's marine practice, whose firm has published a Maritime M&A Risk Guide aimed at buyers, sellers and investors pursuing deals across the maritime industry.

Private equity firms, strategic buyers and marine operators chase acquisitions to add assets, enter new markets and expand capabilities. But buying a marine business is not buying a traditional operating company. Vessels, waterfront assets, specialized labor, complex contracts, environmental exposures, regulatory requirements and increasingly connected technology all sit behind the earnings line — and any of them can materially change the economics of an otherwise attractive transaction.

Brigance puts it bluntly: "Financial diligence tells a buyer what a company earns. Marine risk diligence should help determine whether the assets and operations behind those earnings can sustain them."

What does 'Quality of Risk' actually mean?

Two marine companies can post similar earnings yet carry vastly different levels of operational volatility, capital requirements and liability. One runs well-maintained assets backed by disciplined safety and risk-management practices. The other carries deferred maintenance, aging infrastructure, unresolved claims and heavy workforce dependencies. Identifying those differences before closing is the whole point of what Brigance calls the Quality of Risk.

The vessel schedule is where the gap shows up first. A schedule may list ownership, age and value, but it will not necessarily reveal upcoming drydock requirements, machinery reliability, maintenance backlogs, casualty history or outstanding survey issues. The same logic applies shoreside. Shipyard dry docks, cranes, fire protection systems and waterfront infrastructure can create significant operational and capital requirements, and terminals may hinge on individual berths or single pieces of critical equipment.

Does the insurance match the operation?

Insurance diligence should go beyond confirming that policies exist and limits look adequate. Historical losses, open claims, reserves, deductibles, self-insured retentions and coverage gaps all reveal how an organization has managed risk over time.

Brigance pushes the question further: does the insurance architecture actually match the operation? Buyers should test whether vessel values, navigation limits and P&I provisions are appropriate; whether crew, longshore and state workers' compensation exposures are classified correctly; and whether ship repair, terminal, stevedoring, pollution and cargo coverages reflect the services the company actually provides. The question is not whether insurance exists. It is whether the program responds to the marine operation as it is actually performed.

Environmental liabilities and the crew problem

Waterfront facilities, shipyards, terminals, fuel systems and vessel operations create exposures that outlive ownership: historical contamination, tanks, sediment and dredging issues, waste handling, stormwater, spill history, vessel pollution and operating permits all warrant review. A buyer needs to know not just whether a condition exists, but whether it could affect safe operations, vessel movement, dredging, fueling, permitting or continued use of the facility.

The human capital factor is distinctly maritime. Licensed mariners, skilled tradespeople and experienced waterfront personnel are hard to replace, so diligence should probe critical-role dependencies, succession, safety performance and labor considerations. Employee classification matters too. State workers' compensation, USL&H and Jones Act exposures can intersect within the same organization, and understanding what employees actually do — and their connection to vessels — is part of pricing that risk.

Contracts, cyber and the first 100 days

Charters, ship repair contracts, terminal agreements, towing arrangements and customer contracts determine who pays when something goes wrong. A profitable contract can still create significant exposure if the company has accepted liabilities its operating controls or insurance cannot support.

Cyber diligence should weigh operational consequences: what happens if a navigation system, terminal platform, crane or berth becomes unavailable, is substitute capacity on hand, and how fast can the operation recover? For marine buyers, technology risk now belongs alongside business interruption and operational resilience.

Representations and warranties insurance can play a role in certain transactions, but Brigance is clear it does not replace strong marine diligence. Once diligence flags a known exposure, the parties can respond through remediation, contractual risk allocation, insurance or the deal economics themselves.

Nor does risk management end at closing. The first 100 days offer a window to clear outstanding maintenance and safety concerns, review open claims, validate asset schedules, align contractor practices, strengthen cyber controls and integrate insurance programs. Ultimately, the buyer acquires more than financial performance — the buyer acquires the operation behind those earnings, and understanding its risks before ownership changes hands is what protects the value the deal was meant to create.
