This letter is in regard to the above referenced comment letter (the “Comment Letter”), addressed to Mr. C. Robert Campbell, Chief Financial Officer of MasTec, Inc. (the “Company”). On behalf of the Company, I confirm receipt of the Comment Letter. In addition, per the telephonic conversation between the Company’s counsel, Ira N.

Your accommodation in this regard is greatly appreciated.
