Item 3.02    Unregistered Sales of Equity Securities

On August 1, 2016, United States Steel Corporation (the “Corporation”) contributed (the “Pension Contribution”) 3,763,643 shares of its common stock, par value $1.00 per share (the “Shares”), to the U. S. Steel Retirement Plan Trust (the “Trust”) which is the funding vehicle for the United States Steel Corporation Plan for Employee Pension Benefits (Revision of 2003) (the “Plan”). The Shares were contributed by the Corporation to the Trust as a voluntary contribution to fund certain of the Corporation’s obligations to the Plan in a private placement transaction made in reliance upon the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended. The Shares were valued by an independent valuation firm for purposes of the contribution at $26.57 per share, or approximately $100 million in the aggregate, which was the closing price of the Corporation’s common stock on the New York Stock Exchange on August 1, 2016.

Item 8.01    Other Events

In connection with the Pension Contribution, the Corporation entered into an agreement with United States Steel and Carnegie Pension Fund, the named fiduciary of the Plan, and Gallagher Fiduciary Advisors, LLC, an independent fiduciary appointed to make investment decisions with respect to the Shares, which provides, among other things, that the Corporation will use its best efforts to cause a registration statement covering the Shares to be declared effective and to maintain its effectiveness until the date on which the Trust no longer holds any of the Shares.
On August 1, 2016, the Corporation filed a prospectus supplement to its registration statement on Form S-3 Registration No. 333-209914 relating to the resale of the Shares.
