<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">On May&nbsp;22, 2013, Wesco Aircraft Holdings,&nbsp;Inc. (the &#147;Company&#148;) announced the pricing of the previously announced public offering of 15,000,000 shares of the Company&#146;s common stock by affiliates of The Carlyle Group (&#147;Carlyle&#148;), at a price to the public of $16.00 per share. Upon completion of the offering, Carlyle will beneficially own approximately 41.0% of the outstanding common stock of the Company. In addition, the underwriters have an option to purchase up to 2,250,000 additional shares from Carlyle. The offering is expected to close and settle on May&nbsp;29, 2013. Carlyle and the directors and officers of the Company have entered into lock-up agreements placing certain restrictions on their sale or transfer of shares of the Company&#146;s common stock for a period of 75 days or, in certain cases, 60 days from the date of the offering. The Company is not selling any shares of common stock in the offering and will not receive any of the proceeds from the offering of shares by Carlyle.</font></p>

Item 7.01
Regulation FD Disclosure.
On May 22, 2013, Wesco Aircraft Holdings, Inc. (the "Company") announced the pricing of the previously announced public offering of 15,000,000 shares of the Company's common stock by affiliates of The Carlyle Group ("Carlyle"), at a price to the public of $16.00 per share. Upon completion of the offering, Carlyle will beneficially own approximately 41.0% of the outstanding common stock of the Company. In addition, the underwriters have an option to purchase up to 2,250,000 additional shares from Carlyle. The offering is expected to close and settle on May 29, 2013. Carlyle and the directors and officers of the Company have entered into lock-up agreements placing certain restrictions on their sale or transfer of shares of the Company's common stock for a period of 75 days or, in certain cases, 60 days from the date of the offering. The Company is not selling any shares of common stock in the offering and will not receive any of the proceeds from the offering of shares by Carlyle.
The Company's press release issued in connection with the offering is furnished as Exhibit 99.1 to this report.
The information in this item (including exhibits) shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, or otherwise subject to the liabilities of Section 18, nor shall it be deemed incorporated by reference into any disclosure document relating to the Company, except to the extent, if any, expressly set forth by specific reference in such filing.
Cautionary Note Regarding Forward-Looking Statements
Certain information in this Current Report contains forward-looking statements with respect to the Company's expectations or beliefs concerning future events. In some cases, you can identify forward-looking statements by terminology such as "guidance," "may," "will," "could," "should," "forecasts," "expects," "intends," "plans," "anticipates," "projects," "outlook," "believes," "estimates," "predicts," "potential," "continue," "preliminary," or the negative of these terms or other comparable terminology. Although the Company believes that such forward-looking statements are reasonable, it cannot assure you that any forward-looking statements will prove to be correct. Such forward-looking statements involve risks, uncertainties, estimates and assumptions that may cause the Company's actual results, performance or achievements to be materially different than those set forth in this news release. In particular, there can be no assurances that the offering by Carlyle will be consummated. Additional information relating to factors that may cause actual results to differ from the Company's forward-looking statements can be found in the Company's filings with the Securities and Exchange Commission, including the Company's Annual Report on Form 10-K for the fiscal year ended September 30, 2012, as supplemented by the Company's Quarterly Reports on Form 10-Q for the quarterly periods ended December 31, 2012 and March 31, 2013.
