Nippon Steel Corporation

IR Briefing on Acquisition of United States Steel Corporation

Transcript

Presented by:

Takahiro Mori, Representative Director and Executive Vice President

Slide 3 Moving Forward Together as the “Best Steelmaker with World-Leading Capabilities”

Overview of the acquisition: Both United States Steel Corporation (“U. S. Steel”) and Nippon Steel Corporation (“Nippon Steel”) have a rich history of providing excellent products and services to our customers, and we have decided to join hands to move forward together through this acquisition. Nippon Steel’s mission to be the ‘Best Steelmaker with World-Leading Capabilities’ aligns closely to U. S. Steel’s mission of ‘Delivering Best for All.”

Slide 4 Contributions to Stakeholders

We believe this acquisition is beneficial for all stakeholders. U. S. Steel shareholders will benefit from the premium in the merger consideration and Nippon Steel shareholders will benefit from substantial profit contribution upon consolidation of U. S. Steel. Customers will benefit from the higher value proposition and quality to meet their growth needs. Employees will benefit from the growth potential of the company this deal unlocks. Additionally, we will honor all labor agreements of U. S. Steel. For communities, we intend to uphold the strong and positive relations in place.

Slide 5 Subsidiary Structure

The transaction will consist of establishing a shell company that will merge with U. S. Steel. This scheme is adopted to minimize the time where the entity is exposed to the equity market, and is a common scheme adopted in U.S. M&A transactions.

Slide 6 Impact on Nippon Steel’s Financial Statements

In terms of cash flow, we intend to make U. S. Steel a wholly owned subsidiary in Q2 or Q3 of the next calendar year so that is when the payment of the merger consideration would be made. U. S. Steel’s total asset of approx. US$20bn and interest-bearing debt of US$18bn will be consolidated into our balance sheet. As a result, the D/E ratio is expected to deteriorate to 0.9x from the current 0.5x. However, this is a profit accretive investment and we expect the D/E ratio to gradually improve towards 0.5x over a not-too-long timeframe. The combined asset size is likely to reach JPY\13.7 trillion.

For the impact to the P/L, if the deal is closed by mid-August of next year, U. S. Steel will be consolidated starting with our Q3 results. U. S. Steel’s profit before tax for the Jan-Sep. period is JPY\170bn and post-tax profit of \140bn, which annualized is over \200bn, implying a substantial profit contribution.

Slide 7 Rationale

Slide 8 Toward a group with greater global expansion

This acquisition will have a very significant impact to our global strategy. Nippon Steel’s vision is to achieve a “100 Mil. Ton and \1 trillion” scale. Our current global crude steel capacity stands at 66 mil. tons which will increase to 86 mil. tons by the addition of U. S. Steel’s capacity of 20 mil. tons. Furthermore, the capacity expansions underway and planned in India means that achieving this vision is now well within reach.

Slide 9 This acquisition aligns with Nippon Steel’s global strategy

This acquisition is an ideal fit to our global strategy. The key points of our global expansion policy are (a) markets with high visibility of demand growth, (b) markets where we can leverage our technologies and product capabilities, (c) markets where we can expand the integrated steel mill capacity to capture the value-added from upstream and (d) to acquire brownfield capacity through M&As that will not add incremental capacity to that market. All these points are realized in this acquisition. Realizing this deal will bring our global strategy nearer to completion together with the India expansions, the footprint in our home market of the ASEAN region, and through this acquisition in the U.S., a developed economy and the largest consumer of high-grade steel in the world.

Slide 10 Attractiveness of U.S. Steel Market

We can discuss the attractiveness of the U. S. Steel market endlessly, but the U.S. is the largest steel market among developed economies. Globally speaking, it ranks after India and China in terms of steel demand and has the potential for growth for high-grade steel products. In addition, U.S. steel demand is likely to grow further given population growth, availability of cheap energy resources and the revival of U.S.-based manufacturing due to global divisions leading to economic blocs. Furthermore, fiscal spending based on infrastructure investment for infrastructure is likely to increase steel demand. On the other hand, supply side is opportunistic and is not dependent on exports and primarily supplies the country’s domestic steel demand. The U.S. steel market is one of the most attractive markets in the world.

Slide 11 Creating new value by combining the technologies of both Nippon Steel and U. S. Steel

The areas of synergies are product line-up, operation and equipment technology and decarbonization technologies, where there is scope for mutual complementarity. Areas where Nippon Steel’s technology is advanced can be leveraged to strengthen U. S. Steel’s capabilities and increase demand for its products, which should contribute to the overall U.S. economy as well as growth to Nippon Steel. We intend to provide more details on synergies, post-close.

Share 12 Shared commitment: to decarbonize by 2050

Both companies share the common goal to achieve decarbonization by 2050 although the methods and pathways differ. Nippon Steel is pursuing technology-oriented paths comprised of the 3 breakthrough innovations. U. S. Steel is primarily pursuing CCS to achieve net zero. There is room to leverage the best practices of both pathways to achieve the common commitment that can lead to synergies carbon neutral initiatives.

Slide 14 Overview of U. S. Steel

U. S. Steel’s manufacturing locations within U.S. consists of 4 main business domains of steel sheet, electric arc furnace (EAF) mini-mill, steel pipe production and a Slovakian production site in Europe. Main product categories are steel sheets and pipes and tubes. Raw steel production capacity is 17 mil. short tons or under-16 mil. metric tons in the U.S. plus over-4 mil. metric tons in Europe, bringing total capacity to over-20 mil. tons. U. S. Steel is fully self-sufficient in iron ore supplies with pellet production volume of 20 mil. tons from its in-house mines of Minntac and Keetac that produces iron ores with quality competitiveness.

Slide 15 Strengths of U. S. Steel

U. S. Steel is a powerful brand underpinned by its rich history with long-standing trust built with customers. We will maintain the brand name of U. S. Steel, given the importance of the brand to customers and employees. In addition, the well-balanced production base comprising of mines to blast furnaces (BFs) and EAFs make for a powerful and effective structure – something Nippon Steel has yet to achieve. U. S. Steel’s mines are also competitive on a standalone basis. Other strengths include a highly talented workforce and management that result in high employee retention and strong intellectual property (IP) portfolio. U. S. Steel’s balance sheet has improved significantly, thanks to the numerous reforms carried out by the current CEO, including the decision to acquire the US mini-mill company. Through our due diligence process, we were positively surprised at how much care is taken to maintain facilities, with not a speck of dust at the facilities we visited which is a reflection of the CEO’s strong emphasis on care and maintenance. In addition, they take great care in their people. Safety is strongly emphasized, so much so that conversations almost always start with the topic of safety. I believe this is a testament to the CEO’s deep roots in the manufacturing industry, including his 32-year career at Caterpillar.

Slide 16 Strengths of U. S. Steel – Strategic Investments

U. S. Steel is moving forward with the strategic investments such as its Keetac mine to build a DR-grade pellets facility. The pig iron caster facility at Gary Works investment should help to improve EAF’s cost competitiveness by using the ore from the mines to make pig iron, given that high-quality scrap metal prices are likely to increase in the scramble to secure scrap metal in the future.

Big River’s investment for non-grain oriented electric steel sheet and galvanizing line are both cutting edge facilities that should improve competitiveness. The capacity will nearly double with Big River 2 which is expected to come on stream in 2024.

From an investor’s perspective, U. S. Steel’s attractiveness is these strategic investments that are likely to start contributing from next year onwards and thereby contribute to cash generation.

Slide 17 Strengths of U. S. Steel – State-of-the-art Mini Mill

Both the Big River Steel and Big River 2 are state-of-the-art mini mills even when compared to other North American facilities. What was particularly impressive was that these investments were carried on budget and on schedule, which speaks to the strong discipline of U. S. Steel.

Slide 18 Strengths of U. S. Steel – Flat-rolled Business Profitability

Given the 100% self-sufficiency of ore supplies, U. S. Steel’s profitability of flat-rolled products made from conventional BFs is significant and has high competitiveness. Flat products such as automotive steel sheet are made and supplied to the likes of GM and Toyota, which testifies to the quality of U. S. Steel’s products.

This ends my presentation on the points I wanted to highlight on U. S. Steel. Remaining slides concern Nippon Steel for the purpose of investors and shareholders of U. S. Steel. I am confident that coming together will enable both companies to reach greater heights.

With that I would like to end my presentation. Thank you for your attention.
