See "Item 2.01 -  Completion  of  Acquisition  or  Disposition  of  Assets"  for
description of material definitive agreement entered into.

Item 2.01 - Completion of Acquisition or Disposition of Assets

On August 23, 2004,  Amcast Industrial  Corporation  ("Amcast" or the "Company")
completed  the  sale  of the  assets  of its  Aluminum  Components  business  to
Park-Ohio  Holdings  Corp.  (Nasdaq:  PKOH).  The  sale of  Aluminum  Components
includes the operations of the Company's  Wapakoneta,  Ohio, Richmond,  Indiana,
and Cedarburg, Wisconsin plants.

The Aluminum Components business produces cast metal products for sale to global
original  equipment  manufacturers  and  tier-one  suppliers  in the  automotive
industry.  Products  manufactured  include aluminum  castings for suspension and
brake systems for use on automobiles and light trucks.

The Company received $9.5 million for the assets sold, of which $8.8 million was
used to reduce the Company's outstanding debt.

There is no material  relationship  between the Purchaser and the Company or any
affiliate, director, officer, or associate of the Company.

A copy of the Purchase Agreement is Exhibit 2.1 to this Report.

   Notes to Pro Forma Condensed Consolidated Financial Statements (Unaudited)

(1)  As  reported  on a Form 8-K filed on  August  2, 2004 by Amcast  Industrial
     Corporation ("Amcast"),  Amcast sold most of the assets of its Flow Control
     segment to a U.S.  subsidiary of the Dutch group Aalberts  Industries  N.V.
     (Amsterdam: AALB) on August 2, 2004. The "Flow Control Divestiture" section
     of the pro forma consolidated condensed financial statements (unaudited) is
     presented to give effect for this sale.

(2)  Variance of $3,088  between total assets of Amcast  Industrial  Corporation
     Historical and Amcast Industrial  Corporation Flow Control  Divestiture Pro
     Forma balance sheets is due to the Flow Control Divested Companies share of
     long-term  deferred  taxes.  The Flow Control  Divested  Companies share of
     Amcast's long-term  deferred taxes are recorded in deferred  liabilities on
     the Flow Control Divested  Companies balance sheet,  however this amount is
     part of a total deferred tax asset, recorded in other assets, on the Amcast
     Industrial Corporation Historical balance sheet.

(3)  The "Aluminum Components Divestiture" section of the pro forma consolidated
     condensed financial statements  (unaudited) is presented to give effect for
     the  sale  that is  being  reported  in  this  8-K  filing,  as well as the
     Company's previous sale of its Flow Control segment described in Note (1).

(4)  Variance of $6,120  between total assets of Amcast  Industrial  Corporation
     Flow  Control  Divestiture  Pro Forma  and  Amcast  Industrial  Corporation
     Aluminum  Components  Divestiture  Pro Forma  balance  sheets is due to the
     Aluminum  Components  Divested Companies share of long-term deferred taxes.
     The Aluminum  Components  Divested  Companies  share of Amcast's  long-term
     deferred  taxes  are  recorded  in  deferred  liabilities  on the  Aluminum
     Components Divested Companies balance sheet, however this amount is part of
     a total  deferred  tax  asset,  recorded  in other  assets,  on the  Amcast
     Industrial Corporation Historical balance sheet.
