1.	On May 15, 2006, we filed with the Securities and Exchange Commission in Item 7.01 of a current report
	on Form 8-K, which contained the following information:

The Company announced in a press release issued on May 15, 2006 that it has concluded its review of strategic alternatives and has determined to continue to pursue its long-term strategy to maximize shareholder value. On November 18, 2005, Haynes International, Inc. (the "Company") announced that its Board of Directors had appointed a Special Committee of independent directors to explore strategic alternatives, including a potential sale of the Company to a third party, and that the Company had engaged Houlihan Lokey Howard & Zukin to act as the Company’s financial advisor in identifying and exploring its strategic alternatives. As part of the review process, with Houlihan’s assistance, the Special Committee considered various alternatives. During the process, the Company received several non-binding indications of interest to acquire the Company or to engage in other transactions with the Company. The best alternative presented to the Company was a combination of proposals (the “Proposed Transactions”) that, if consummated, was not expected to result in consideration to the Company’s stockholders in excess of $30.00 per fully diluted share. As a pre-condition to finalizing a binding acquisition agreement , the Company was required to contact certain large shareholders to evaluate their support for a transaction. Each of these shareholders separately informed the Company either that it would not support a transaction below the then-current market price or that it would not support a transaction at this level. Therefore, the Company informed the potential acquirer that it would not be able to obtain support from such shareholders, whereupon the potential acquirer declined to increase its offer and withdrew its non-binding offer, thereby eliminating a key component of the Proposed Transactions. The Board of Directors, upon the recommendation of the Special Committee, decided to conclude the review of strategic alternatives and instructed Company management to continue to pursue its long-term growth strategy as described in its Form 10-K, although this would not preclude the Company from considering strategic opportunities should they arise or be developed.

2.On April 6, 2006, we filed with the Securities and Exchange Commission a current report on Form 8-K, which contained the following information:

Item 1.01. Entry into Material Definitive Agreement.

The Options may be exercised with respect to 33-1/3 percent of the total number of shares covered by the Option on March 31, 2007, and with respect to an additional 33-1/3 percent on each of March 31, 2008 and March 31, 2009, respectively. When the Option becomes exercisable with respect to any shares, those shares may be purchased for $31.00 per share, at any time, or from time to time, in whole or in part, for a period of ten years from the date of grant.
