PROSPECTUS SUPPLEMENT
 

This prospectus supplement filed pursuant to Rule 424(b)(3)
Registration No. 333-120246
PROSPECTUS SUPPLEMENT
     This is a supplement, dated November 3, 2005, to the prospectus which forms a part of Amendment No. 1 to the Form S-3 Registration Statement (No. 333-120246) filed on January 14, 2005, by Henry Schein, Inc.
     We originally issued the notes to which this supplement relates in a private placement on August 9, 2004. The notes were resold by the initial purchasers to qualified institutional buyers, as such term is defined by Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), in transactions exempt from registration under the Securities Act. The notes and the shares of common stock issuable upon conversion of the notes that may be offered pursuant to the prospectus and this supplement are being offered by the selling securityholders, which includes their transferees, distributees, pledgees or donees or their successors.
     The following table sets forth information with respect to the selling securityholders and the principal amount of notes beneficially owned by each selling securityholder that may be offered pursuant to the prospectus and this supplement. The information contained in this supplement is based on information provided by or on behalf of the selling securityholders on or prior to November 2, 2005. The selling securityholders may offer all, some or none of the notes or the common stock into which the notes are convertible. Because the selling securityholders may offer all or some portion of the notes or the common stock, we cannot estimate the amount of the notes or the common stock that will be held by the selling securityholders upon termination of any of these sales. In addition, the selling securityholders identified below may have sold, transferred or otherwise disposed of all or a portion of their notes, or acquired additional notes, since the date on which they provided the information regarding their notes in transactions exempt from the registration requirements of the Securities Act. Accordingly, the information provided here for any particular securityholder may understate or overstate, as the case may be, such securityholder’s current ownership. The aggregate principal amount of notes outstanding as of the date of this supplement is $240.0 million, which is the aggregate principal amount of notes registered pursuant to the Registration Statement of which this prospectus is a part. The percentage of notes outstanding beneficially owned by each selling securityholder is based on $240.0 million aggregate principal amount of notes outstanding.
     The number of shares of common stock issuable upon conversion of the notes shown in the table below assumes conversion of the full amount of notes held by each selling securityholder at the current conversion rate of 10.7898 shares per $1,000 principal amount of notes and a cash payment in lieu of any fractional shares. This conversion price is subject to adjustment in certain events. Accordingly, the number of conversion shares may increase or decrease from time to time. No selling securityholder named in the table below beneficially owns one percent or more of our common stock, based on 87,166,433 shares of common stock outstanding on October 26, 2005. Information concerning other selling securityholders will be set

 


 

forth in supplements to the prospectus, or if appropriate, post-effective amendments to the Registration Statement of which the prospectus is a part, from time to time, if required. The number of shares of common stock owned by the other selling securityholders or any future transfers from any such holder assumes that they do not beneficially own any common stock other than common stock into which the notes are convertible.
