MasTec Announces 2003 Results of Operations

April 13, 2004

MIAMI, April 13 /PRNewswire-FirstCall/ -- MasTec, Inc. (NYSE: MTZ) today announced a net loss of $39.7 million ($0.83 per share) on revenue of $873.9 million for the year ended December 31, 2003, compared with a net loss of $128.8 million ($2.15 per share) on revenue of $838.1 million for the prior year. As a result of the continuing evaluation of the issues described below, the 2003 loss may be subject to adjustment; however, the Company does not currently expect any such adjustment to be material.

During its review and analysis of the Company's annual results, MasTec's management identified a number of matters that impacted current and prior period operating results. These included additional reserves for bad debts and inventory, cost overruns and projected losses on certain projects, valuation reserves for state deferred tax assets, revenues recognized on various contracts, work in progress and inventory overstatements at a Canadian subsidiary, the closing of Brazilian operations, the accrual for certain insurance reserves which was complicated by the receivership of a prior insurance carrier, and other items. Management concluded that these matters required a detailed analysis and evaluation to determine the appropriate accounting treatment. Some of these issues may require restatements of amounts previously reported. As a result, final quarterly and annual financial statements are not a part of this release, but will be presented when the evaluation of these items is finalized by management and the Company's auditors. These items will be more fully described in the 2003 10-K, when filed, and the related conference call. The Company also expects to issue new guidance in conjunction with the upcoming 10-K filing and conference call. Currently, MasTec expects to file its 10-K the week of April 19th.

As a result of its 2003 loss, MasTec also announced that it is in the process of obtaining an amendment to its $125 million credit facility which the Company believes will be completed prior to the filing of its 10-K.

Austin J. Shanfelter, MasTec's President and CEO stated, "Our 2003 results are unacceptable. However, regardless of the challenges involved, we are committed to taking whatever actions are necessary in 2004 to return our company to profitability."

Mr. Shanfelter continued, "Certainly, one of our highest priorities in 2004 will be improving our financial controls and reporting. In that regard, I am particularly pleased that David Sasnett will be taking over our CFO role later this month. David has already proven to be an excellent addition to the MasTec team and he has been instrumental in assisting our management team, audit committee, and external auditors with the accounting issues that impacted 2003.

In addition to improving our financial functions, David will assist me and the other members of our team in the development of new strategic initiatives, the pursuit of operational efficiencies and cost savings, and in improving the bottom line.

Although competition remains strong, the outlook for our service offerings is encouraging. We will be a more disciplined company in 2004 and, once we get through the seasonally slow first quarter, you should see marked improvement in our operational performance."

Executives of MasTec will also hold a conference call with the investment community on Tuesday morning, April 13, at 9:00 a.m. ET to discuss year-end results. The call-in number for the conference call is (913) 981-5510 and the replay is (719) 457-0820, with pass code 457205. The replay will run from April 14 until April 28.
