Cliffs Corporate Announcement

Message from Gary B. Halverson Shareholder Engagement Dear Colleague, Earlier today, one of our shareholders, Casablanca Capital, made a filing with the Securities and Exchange Commission and issued a press release expressing its views regarding our Company. We welcome open communications with all of our shareholders and value their input toward the collective goal shared by Cliffs’ Board and management, which is to enhance long-term shareholder value. Cliffs has held productive preliminary conversations with Casablanca Capital and looks forward to continuing the dialogue to better understand their assumptions, projections and overall views. As part of the our goal to enhance shareholder value, over the last year, we made significant changes to strengthen the Board of Directors and management team, including the addition of four new board members and a new chairman. Since these changes were made, management has taken steps to improve its financial and operating performance across all of its businesses. Looking ahead, we expect to continue to make progress on reducing costs, strengthening our balance sheet with cash flows from operations, and taking a disciplined approach to capital spending. We will continue to evaluate the strategic fit and value creation potential of all the Company’s assets as part of that process. As we focus on executing our strategy to improve financial and operating performance, the management team is open to constructive dialogue with all shareholders. As a result, Cliffs will continue to review and consider ideas that may create additional value. Our focus remains on providing the world’s largest and fastest growing steel markets with world-class iron ore and coal products. The most important thing that you can do is stay focused on your day-to-day responsibilities, and continue to provide our customers with the outstanding service that they have come to expect from us. I understand you may have some further questions. For your convenience, FAQs have been developed to address your concerns. You can download the document from our intranet, OneCliffs. As always, it is important for us to speak with one voice.
