PAID ADVERTISEMENT NIPPON STEEL SS United States Steel Corporation Nippon Steel is Committed to Pennsylvania Dear Pennsylvanians, Nippon Steel is excited to grow U. S. Steel into the best steelmaker in America, making it more technologically advanced, more environmentally sustainable, and better able to manufacture high-quality American-made steel products. This partnership will protect and grow jobs. It will ensure that plants stay in Pennsylvania and it will increase the supplier base across the state. We know you've had questions about our plans for this iconic company. Over the past few months, we've met with union leaders, elected officials, and community members to listen and share our story. I want to take this opportunity to tell you how our partnership will benefit U.S. Steel, its workers, the American steel industry, and communities across Pennsylvania. The United States is currently the world's fastest growing market for high-grade steel. We see a massive opportunity to support U.S. Steel's focus on manufacturing high-quality products to meet the increasing global demand for steel and strengthen America's supply chain for critical domestic industries. Nippon Steel's global footprint and leading-edge advanced technologies combined with U. S. Steel's trusted brand and exceptional workforce will create America's best steelmaker-with significant benefits for suppliers and vendors throughout Pennsylvania. We're excited to build on our 40+ years of successfully managing steel facilities in America, including the legendary Standard Steel in Burnham, Pennsylvania and Wheeling Nippon Steel in West Virginia - a major customer of U. S. Steel's Mon Valley Works. We have also been importing metallurgical coal to Japan from Pennsylvania and other states for the past 70 years. We want to invest in all of U. S. Steel. .There is great value to be realized across the company's iron ore, blast furnace, and electric arc furnace facilities. Every corner of the company will benefit from our sizable R&D budget and our world-leading technologies related to product, operational, and decarbonization. Our partnership will serve U. S. Steel's customers more efficiently and sustainably across automotive, renewable energy, infrastructure, and other key industries. We look forward to supporting Pennsylvania's best-in-class research institutions, and we are already in discussions with Carnegie Mellon University to advance green technology in steelmaking. We want U. S. Steel's employees to share in its future success - including its unionized workforce. We will continue to honor all agreements currently in place between the United Steelworkers (USW) and U. S. Steel. As we are three times larger than U. S. Steel and enjoy an investment-grade credit rating, Nippon Steel has the financial wherewithal to uphold these agreements. We remain engaged with the USW, and have offered a number of specific commitments related to job security. investment in facilities, and technology sharing. The best of U. S. Steel is here to stay. We will not cut jobs, close facilities, or move production overseas as a result of this transaction. U. S. Steel's powerful name and brand will not change. Not only are we keeping the Pittsburgh headquarters which other bidders would not be able to do - but we are planning to move Nippon Steel's existing U.S. headquarters from Houston to Pittsburgh. We're confident that Nippon Steel's financial and technological strength make us the right partner to ensure that Pennsylvania will be home to a world-leading steelmaker- and we look forward to a long and prosperous partnership with Keystone State.
