GLASS LEWIS RECOMMENDS TDS SHAREHOLDERS VOTE FOR PROPOSED PLAN TO RECLASSIFY SPECIAL COMMON SHARES

Company Strongly Disagrees with Conflicting ISS Recommendation and
Urges Shareholders to Support Plan

CHICAGO — Sept. 27, 2011 — Telephone and Data Systems, Inc. [NYSE: TDS, TDS.S] today issued the following comments in response to the Glass, Lewis & Co., LLC (“Glass Lewis”) and the Institutional Shareholder Services’ (“ISS”) reports regarding the proposed amendments to the TDS certificate of incorporation.  The proposals include a share consolidation amendment to reclassify TDS Special Common Shares as Common Shares on a one-for-one basis, resulting in a single class of publicly-traded common stock, and a vote amendment, which will set the Series A Common Shares voting rights at current levels.

Glass Lewis Report

“We are pleased that Glass Lewis recognized the merits of our proposals,” said Kenneth R. Meyers, TDS Executive Vice President and Chief Financial Officer.  “We strongly believe that the proposed one-for-one exchange ratio is fair and appropriate and that the proposed amendments will simplify our capital structure, provide all shareholders with improved liquidity and visibility, and give TDS greater financial and strategic flexibility.”

In its report, Glass Lewis noted that “…voting structures involving multiple classes of stock are not in the best interest of shareholders” and that, “…investors will benefit from the clarity of having to evaluate only a single class of publicly-traded stock.”

ISS Report

Commenting on the ISS report, Meyers said, “We strongly disagree with ISS’ recommendation that holders of our Common Shares vote against the proposed amendments.  The economic rights of the two share classes are equivalent, the exchange ratio is consistent with precedent transactions, and we believe the proposals will benefit all shareholders significantly.  We also believe the holders of Common shares will benefit from the share consolidation because the newly consolidated share class will have improved liquidity, thus providing potential access to

additional indexes and broader investment appeal.  We believe that by recommending that Common shareholders vote against the proposal, ISS is asking Common shareholders to forego the benefits and accept the risk of losing their liquidity advantage in the future.”

The ISS report concludes, and we agree, that,  “...the board is rightly concerned about the persistent trading discount of TDS.S” and that, “…there are tangible benefits for the company as a whole in simplifying the capital structure, and it is clear why the board is considering such an action.”

Commenting on the ISS recommendation, Meyers said, “We saw three reclassification precedents that had similar structures to ours with Common Shares and Special Common Shares, where the higher vote stock traded at a greater than 10 percent premium to the lower, no-vote stock.  In two of those situations, the reclassification ratio was one-to-one and ISS recommended in favor of each of those transactions.  In the third transaction, a market ratio was used and ISS split its recommendation.  ISS’ current position ignores these precedents.

“ISS also noted that the TDS Common stock declined at announcement, and since announcement, in excess of various market indices.  However, market volatility has been unusually high in the wireless arena.  Looking at stock price performance since one week prior to the announcement, the TDS Common stock is down less than its three primary comparables: Sprint, MetroPCS and Leap.”

The TDS Board of Directors unanimously approved the amendments and unanimously recommends that shareholders vote “FOR” the proposals at its special meeting of shareholders, to be held on October 6, 2011.
