1 Nippon Steel Completes $14.1B US Steel Acquisition

Nippon Steel Completes $14.1B US Steel Acquisition

On June 18, 2025, a historic moment arrived for the global steel industry. Nippon Steel Corporation officially completed its acquisition of US Steel, making the American steel giant a wholly-owned subsidiary. This $14.1 billion deal, finalized after 18 months of negotiations and with President Trump’s approval, represents one of the largest Japanese acquisitions of an American company in history.

With this acquisition, Nippon Steel’s global crude steel production capacity reaches 86 million tons per year, positioning it as the world’s second-largest steelmaker after China’s Baowu Steel Group. This marks a significant step toward reclaiming the global leadership position Nippon Steel held from 1970 to 2000.

A Long Journey Through Political Headwinds

This acquisition transcended typical corporate transactions, becoming a complex political battleground. Since the deal’s announcement in December 2023, it faced fierce domestic opposition in the United States.

United Steelworkers’ Strong Opposition

Immediately after the announcement, the United Steelworkers (USW) union strongly opposed the deal, citing concerns about “employment impacts” and “national security.” The USW, representing American steel workers’ interests, is a powerful organization whose influence significantly affected political decisions.

The union’s concerns centered on potential job cuts and production facility relocations overseas after the Japanese acquisition. There was also deep-seated resistance to foreign control over America’s foundational steel industry.

President Biden’s Blocking Order

Responding to union opposition, former President Biden moved to issue an executive order blocking the acquisition, citing national security concerns. Nippon Steel challenged this decision, filing multiple lawsuits in federal court arguing that the order “distorted procedures for political purposes” and lacked legitimate grounds.

Nippon Steel and US Steel sought to invalidate President Biden’s order and the Committee on Foreign Investment in the United States (CFIUS) review, continuing their legal battle to assert the acquisition’s legitimacy.

Presidential Election Battleground

Notably, US Steel’s headquarters in Pennsylvania became a crucial factor, as the state was a key battleground in the presidential election. This geographic element elevated the acquisition to a political flashpoint.

As a presidential candidate, Trump claimed he would prevent Japanese companies from “taking over” important American companies, appealing to working-class voters. President Biden, avoiding criticism from Trump, emphasized the importance of maintaining “a strong American steel company run by American steelworkers” and showed caution toward the acquisition.

Vice President Harris, upon becoming a presidential candidate, also declared opposition to the acquisition, stating that “domestic control of steel production is paramount.” The acquisition thus became a major campaign issue regarding American industrial and employment policies.

Historical Anti-Japanese Sentiment

Opposition to the acquisition had deeper roots. Analysis suggests that America’s historical perception of Japan as “unfair” since the Pearl Harbor attack still influences public sentiment. Additionally, memories of Japanese companies’ extensive acquisitions of American real estate and entertainment companies in the late 1980s and early 1990s, termed an “invasion,” affected political judgment.

Some analysts suggest that if the acquisition had been proposed by British or Dutch companies, it might not have become such a significant political issue. The fact that it was a Japanese company triggered particular wariness.

President Trump’s “Historic Decision”

However, the situation changed dramatically when Trump assumed the presidency in January 2025. President Trump shifted to welcoming increased investment in America and directed CFIUS to re-examine the deal. Finally, on June 13, 2025, he signed an executive order approving the acquisition.

Nippon Steel Chairman and CEO Eiji Hashimoto praised this as a “historic decision” and expressed deep gratitude to President Trump. Hashimoto stated, “This acquisition benefits both Japan and America and could represent a new era of development for Japanese manufacturing.”

National Security Agreement and the “Golden Share”: Unprecedented Compromise

As a condition for approval, Nippon Steel and US Steel signed a National Security Agreement (NSA) with the US government. This agreement includes strict conditions to protect American steel industry independence and employment.

Introduction and Implications of the Golden Share

The most symbolic element of the NSA is the US government’s “golden share.” While carrying no voting rights, this golden share holds powerful veto authority over US Steel’s major management decisions.

Matters requiring US government consent include:

Changes to US Steel’s headquarters location (Pittsburgh, Pennsylvania)
Changes to US Steel’s company name
Transfer of production or employment outside the United States
Reduction of capital investments promised in the NSA
Significant acquisitions of competing businesses within the United States
Closure or suspension of existing manufacturing facilities
Certain matters related to trade and labor

Interestingly, Nippon Steel proposed this golden share arrangement. Chairman Hashimoto emphasized that since the golden share’s scope is limited to certain key matters, “management freedom and profitability are secured, and this agreement is fully satisfactory for our company.”

Americanization of Management Structure

The NSA also established strict requirements for US Steel’s management structure:

A majority of the board of directors must be US citizens
At least three independent directors must be US citizens
Core management positions, including the CEO, must be held by US citizens

However, Nippon Steel Vice Chairman Hiroki Mori will serve as US Steel’s chairman, and approximately 40 technical staff will be dispatched to facilitate local exchange. This balance allows Nippon Steel to leverage its technical expertise while maintaining American management autonomy.

Non-interference in Trade Issues

Nippon Steel and its US subsidiary, Nippon Steel North America, Inc. (NSNA), have committed not to interfere with US Steel’s trade-related decisions or requests for trade measures under US law against unfair trade practices. This guarantees the independence of American trade policy.

Industrial Policy Aspects

Chairman Hashimoto views the NSA content as “more industrial and employment policy than security policy.” The US government expects Nippon Steel to fully contribute its technology to regenerate and develop US Steel, which aligns with “American manufacturing revival” and “US regeneration.”

Indeed, multiple Japanese government officials view this positively, noting that “achieving 100% subsidiary status and the unlikely activation of the golden share means Nippon Steel gained more than it conceded.” Similar arrangements exist in overseas operations in India and elsewhere, ensuring management freedom.

Nippon Steel’s Strategic Vision: Path to “World No.1 Comprehensive Steelmaker”

For Nippon Steel, the US Steel acquisition is not merely about expansion but a strategic move to realize its grand vision of becoming the “world’s No.1 comprehensive steelmaker.”

Returning to Lost Global Leadership

Nippon Steel, as the former Nippon Steel Corporation, was the world’s largest steelmaker by crude steel production from 1970 to 2000. However, with the rise of emerging economies, particularly China, it had fallen to fourth place globally by 2023. This acquisition is positioned as a “necessary strategy” to reclaim the top position.

The acquisition brings Nippon Steel’s global crude steel production capacity to 86 million tons per year, making it the world’s second-largest steelmaker after China’s Baowu Steel Group. This represents significant progress toward the company’s strategic goal of “100 million tons of global crude steel production capacity.”

Strategic Importance of the US Market

The US market holds special significance for Nippon Steel. It’s the only developed country with long-term population growth expectations and anticipated high domestic steel demand. Particularly, it’s the largest market for high-grade steel products like automotive steel, where Nippon Steel excels, and tariff protection provides a stable market environment.

By establishing production facilities within the US, Nippon Steel can avoid protectionist policies like the Trump administration’s proposed “50% steel tariffs.” The company will significantly expand its production and sales channels in the US market, enhancing competitiveness in automotive and construction sectors.

Stabilizing Resource Procurement

US Steel’s iron ore mines in Minnesota are valuable assets for Nippon Steel. With US Steel’s 100% iron ore self-sufficiency rate, these mines will contribute to stabilizing raw material procurement and enhancing cost competitiveness. Reducing raw material price volatility risk ensures long-term competitive advantages.

Nippon Steel aims to evolve its raw materials business from “procurement” to “business operations,” seeking stable procurement and mitigation of market fluctuation impacts. US Steel’s mining assets are crucial elements of this strategy.

Technological Innovation and Sustainability: Challenge Toward 2050 Carbon Neutrality

Nippon Steel has established its “Carbon Neutral Vision 2050,” positioning climate change response as a core management priority. The US Steel acquisition is also an important step toward achieving this ambitious goal.

Development of Innovative Steelmaking Processes

Aiming for carbon-neutral society realization by 2050, Nippon Steel is focusing development on two technological options:

Blast furnace decarbonization: Using hydrogen as a reducing agent instead of traditional coke through blast furnace hydrogen reduction technology
Electric furnace melting of pre-reduced iron: New process melting direct reduced iron (DRI) in electric furnaces

Blast furnace hydrogen reduction technology is particularly innovative, with Nippon Steel leading global development. The company is also considering early implementation of electric furnaces to reliably achieve 2030 CO₂ reduction targets.

Utilizing US Steel’s Electric Furnace Assets

US Steel’s advanced electric arc furnace minimill, Big River Steel, is a valuable asset for strengthening decarbonization efforts. Electric furnaces emit less CO₂ than blast furnaces and contribute to a circular economy by using scrap steel as raw material.

Nippon Steel plans to introduce advanced technologies including blast furnace CO₂ reduction technology to US Steel, promoting efforts toward 2050 carbon neutrality through technological fusion between the companies.

Converting Environmental Value to Economic Value

Decarbonized steelmaking involves three major cost increases:

Increased R&D expenses
Expanded capital investment
Rising operating costs

For steel products subject to international competition, converting CO₂ reduction “environmental value” into product “economic value” (sales price) is a major challenge. Nippon Steel is advancing initiatives to form green steel markets:

Promoting international standardization of green steel
Creating purchasing incentives and support mechanisms
Strengthening cooperation with governments, industry associations, standardization organizations, and academics

Strengthening Environmental Management

Nippon Steel implements comprehensive measures against environmental risks at steel plants:

Organizational structure: Systematic promotion through Environmental Policy Planning Committee and Green Transformation Promotion Committee

Financial Impact and Funding Strategy

This $36 billion acquisition and investment will significantly impact Nippon Steel’s finances. However, the company plans to maintain financial health through careful financial strategy.

Funding Methods

Acquisition funding will primarily come from bridge loans from major banks. This will change the debt-to-equity (D/E) ratio as follows:

Pre-acquisition: 0.5
Immediately post-acquisition: Approximately 0.8-0.9
FY2024 target: 0.7 range

The company aims for early recovery of financial health through optimal funding methods.

Regarding Equity Financing Possibilities

While markets have speculated about potential equity financing to cover the massive acquisition and investment costs, Vice Chairman Mori stated clearly, “We are not considering equity financing that would cause dilution.” This demonstrates the policy to minimize impact on existing shareholders.

However, Jefferies has downgraded Nippon Steel’s investment rating, viewing the US Steel acquisition as a burden on stock price due to concerns about:

Earnings forecast downgrade risk
Possibility of equity financing
Funding for additional investment
Post-merger integration (PMI) issues

US Steel’s Challenges and Path to Regeneration

While US Steel is an iconic American steel company, it has faced challenging business conditions in recent years. Nippon Steel plans to overcome these challenges and regenerate US Steel.

Long-term Performance Decline

Despite its large scale, US Steel recorded losses in seven of the past ten years, suffering from long-term performance decline. Main factors include:

Nippon Steel’s US Steel acquisition could significantly impact the global steel industry. This strategic move comes amid major environmental changes including US-China trade friction, rising protectionism, and decarbonization demands.

Model for Responding to Protectionism

Unless the Trump administration significantly revises tariff policies, there are indications that Japanese and global companies may increasingly avoid US business. However, Nippon Steel has adopted a strategy to capture the market by expanding US investment.

This represents a management strategy premised on increasing government involvement in economics and business, demonstrating the importance of public-private partnerships. Nippon Steel’s approach could become a reference model for other Japanese companies.

Completion of International Supply Network

The acquisition completion is seen as a step toward “international supply network completion.” Nippon Steel is building a system to reliably capture local demand growth through integrated manufacturing base expansion in “regions where demand growth is certain” and “fields where our technical and product capabilities can be utilized.”

Priority bases include:

United States: Established as the most important base through this acquisition
ASEAN: Expansion into the rapidly growing Southeast Asian market
India: Early investment in a future mega-market

Catalyst for Industry Reorganization

This acquisition may accelerate global steel industry reorganization. As the global steel industry struggles with Chinese oversupply, combining economies of scale with technological capabilities has become key to survival.

Nippon Steel’s successful US Steel acquisition may encourage other steelmakers to pursue cross-border integration or partnerships. Particularly for companies unable to independently fund massive decarbonization investments required by stricter environmental regulations, integration becomes a viable option.

Conclusion: Dawn of a New Era for Japanese Manufacturing

Nippon Steel’s US Steel acquisition has historical significance beyond a mere corporate acquisition. This challenge, involving political compromise while attempting US Steel’s regeneration through technological prowess and massive investment, could become a model for future overseas expansion by Japanese companies.

As Chairman Hashimoto stated, this acquisition “benefits both Japan and America and could represent a new era of development for Japanese manufacturing.” How Nippon Steel, starting anew as the world’s second-largest steelmaker, will enhance global market competitiveness and achieve its ambitious 2050 carbon neutrality goal remains to be seen.

Its success or failure could determine not just Nippon Steel’s future but the entire Japanese manufacturing industry’s trajectory. Facing multifaceted challenges in politics, economics, technology, and environment, Nippon Steel’s challenge to become the “world’s No.1 comprehensive steelmaker” has truly entered a new chapter.
