UNITED STATIONERS INITIATES A $0.26 PER SHARE QUARTERLY CASH DIVIDEND

AND ANNOUNCES A TWO-FOR-ONE STOCK SPLIT

DEERFIELD, Ill., March 1, 2011 — United Stationers Inc. (NASDAQ: USTR) announced today that its Board of Directors has approved a two-for-one stock split of the company’s issued common shares, which will be payable in the form of a 100% stock dividend.  All stockholders will receive one additional share for each share owned at the close of business on the record date of May 16, 2011.  The stock dividend will be payable on May 31, 2011.

Additionally, the Board of Directors has approved initiation of a quarterly cash dividend of $0.26 per pre-split share ($0.13 per post-split share).  The first such cash dividend will be payable April 15, 2011 to stockholders of record as of the close of business on March 15, 2011.

“The combination of a regular quarterly dividend and a stock split reflects confidence in our business strategy and in our ability to generate free cash flow,” said Richard W. Gochnauer, chief executive officer. “We plan to deploy our cash flow in a balanced way to maximize long-term shareholder value creation and maintain our target capital structure. Our capital deployment priorities include continued investments in attractive growth strategies and return of capital to shareholders through dividends and share repurchases.  Additionally, we expect that the actions announced today will enhance trading liquidity and help to make our stock more attractive to a broader investor base.”

The additional shares of common stock to be issued as a result of the stock dividend will be issued in book-entry form on or about May 31, 2011.  Stockholders will be entitled to receive physical stock certificates upon request from the company’s transfer agent, Wells Fargo Bank N.A. Stockholders who have existing stock certificates should retain them.
