Who Owns McDermott Company?

Who owns McDermott now?

The 2024 restructuring left McDermott privately owned by a consortium of institutional creditors after a $450,000,000 liquidity recap and nearly $2,000,000,000 debt reduction, ending years of public-market uncertainty.

Control resides with major global credit funds and institutional lenders that converted claims into equity during the restructuring, steering strategy through a board representing creditor interests.

Ralph Thomas McDermott founded the company in 1923 at age 24, building wooden drilling rigs with his father, J. Ray McDermott; ownership remained tightly held within the McDermott family as a private partnership funding growth via reinvested profits and local backers.

Founding duo

Ralph T. McDermott and J. Ray McDermott founded the firm in 1923, focusing on wooden rigs for Texas oil producers.

Family ownership

Initial equity was concentrated in the McDermott family, with Ralph as the primary equity holder and leader.

Private partnership

The company operated as a private partnership, relying on localized capital and reinvested profits rather than modern VC rounds.

Geographic expansion

Growth moved from Eastland to Luling, then into Louisiana marshlands and early offshore work, driven by specialized equipment ownership.

Vertical integration

Founders pursued vertical integration, controlling vessels and equipment to build a technological moat and protect equity value.

Path to public markets

Control remained tight until incorporation and later public offerings to finance the capital-intensive offshore engineering business.

The early ownership model and reinvestment strategy set the stage for mid-century expansion and eventual public listings as the company transitioned from family-held private partnership to a publicly traded entity; see a concise company timeline in the Brief History of McDermott.

The ownership of McDermott shifted from a broadly held public company to private credit control after the 2018 merger with CB&I and the 2020 Chapter 11 filing; a 2024 deleveraging recapitalization provided $450,000,000 in new liquidity and eliminated $2,000,000,000 of debt, creating the current institutional ownership base.

Current ownership emphasizes cash flow, disciplined bidding, and high-margin offshore and subsea work, with roughly 30,000 employees and strategic focus on the Middle East and energy transition markets; management alignment reflects private credit priorities and reduced leverage.

Major institutional owners after 2024 recap

Ownership concentrated among credit investors who converted debt into equity and drove a deleveraging plan that reshaped strategy and governance.

• HPS Investment Partners, LLC — lead role in new credit facilities and largest equity holder
• The Baupost Group — significant converted debt-to-equity stake
• West Street Infrastructure Partners (Goldman Sachs affiliate) — major infrastructure investor and equity holder
• Senior lenders and additional institutional participants from the 2024 transaction

The McDermott Board of Directors aligns with its private institutional owners, combining representatives from major credit funds and industry executives focused on restructuring; Michael McKelvy leads the board as President and CEO, guiding the company through the 2024 restructuring and execution of a roughly $28 billion backlog.

Voting power is governed by a private shareholders agreement among the consortium of lenders, with voting weight proportional to debt‑to‑equity conversion rather than public share classes, creating a closed‑loop governance system focused on creditor confidence and project delivery.

Board and Voting Dynamics

The board prioritizes creditor-aligned governance, analytical decision-making, and strict oversight of capital allocation and divestitures.

• Major decisions require approval from lead investors with significant voting stakes
• No dual-class or golden share structures; voting tied to conversion stakes
• HPS Investment Partners and similar lead funds hold outsized influence
• Governance emphasizes project risk management tied to the $28 billion backlog

Between 2023 and 2025 McDermott’s ownership profile shifted toward institutional credit and private equity oversight, anchored by a 2024 Amended and Restated credit agreement that secured runway for its project pipeline and prompted leadership changes toward restructuring and energy-transition specialists.

Ownership trends in the EPCI sector favor consolidation and private credit due to offshore capital intensity; McDermott pivoted from aggressive M&A to specialized subsea, LNG and low‑carbon offerings while owners assess a potential public return or secondary sale by 2027.

Capital structure

Post-2024 refinancing increased secured credit exposure and reduced near-term equity dilution, aligning incentives for institutional lenders and private equity backers.

Leadership changes

Several legacy executives exited; new hires specialize in financial restructuring and low‑carbon project delivery to boost project execution and cost control.

Strategic focus

Portfolio now emphasizes subsea systems, LNG infrastructure and decarbonization services rather than broad acquisitive growth, improving margin predictability on large EPC projects.

Market outlook

Owners are evaluating a potential return to public markets or strategic sale by 2027, contingent on delivery of backlog and sustained cash‑flow improvements.
