SCHEDULE TO

     This Amendment No.2 (this “Amendment”) amends and supplements the Tender Offer Statement on Schedule TO (as amended, the “Schedule TO”) initially filed with the Securities and Exchange Commission (the “SEC”) on July 27, 2009. The Schedule TO relates to an offer by WESCO International, Inc., a Delaware corporation (the “Company”). Upon the terms and subject to the conditions set forth in the prospectus dated August 12, 2009 (the “Prospectus”) and the related Letter of Transmittal, the Company is offering to exchange $960 principal amount of its newly issued 6.0% Convertible Senior Debentures due 2029 (the “2029 Debentures”) for each $1,000 principal amount of the Company’s 1.75% Convertible Senior Debentures due 2026 (the “2026 Debentures”) and $1,010 principal amount of the Company’s 2029 Debentures for each $1,000 principal amount of the Company’s 2.625% Convertible Senior Debentures due 2025 (the “2025 Debentures”), provided that the maximum amount of 2029 Debentures that the Company will issue is $345,000,000. We refer to this offer as the “Exchange Offer.”

     The Exchange Offer is subject to the conditions discussed in the Prospectus under “The Exchange Offer — Conditions to the Exchange Offer,” including, among other things, the condition that the Registration Statement to which the Prospectus relates not be subject to a stop order or any proceedings for that purpose and the condition that a minimum aggregate principal amount of 2026 Debentures and 2025 Debentures shall have been tendered such that at least $100.0 million aggregate principal amount of 2029 Debentures will be issued in the Exchange Offer. The Exchange Offer will expire at midnight, New York City time, on August 21, 2009, unless extended or earlier terminated by the Company (such date, as the same may be extended or earlier terminated, the “Expiration Date”).

     This Schedule TO is being filed in satisfaction of the reporting requirements of Rules 13e-4(b)(1) and (c)(2) promulgated under the Securities Exchange Act of 1934, as amended. Except as specifically provided herein, this Amendment does not modify any of the information previously reported on the Schedule TO.
