Safe Harbor Statement

This document contains “forward-looking” statements, as that term is defined by the federal
securities laws, about our financial condition, results of operations and business. Forward-looking
statements include certain anticipated, believed, planned, forecasted, expected, targeted and
estimated results along with Metaldyne’s outlook concerning future results. These forward-looking
statements are subject to numerous assumptions, risks and uncertainties. Because the statements are
subject to risks and uncertainties, actual results may differ materially from those expressed or implied
by the forward-looking statements. We caution readers not to place undue reliance on the statements,
which speak only as of the date hereof. Risks and uncertainties that could cause actual results to vary
materially from those anticipated in the forward-looking statements included in this report include
general economic conditions in the markets in which we operate and industry-based factors such as:
declines in North American automobile and light truck builds, reductions in outsourcing by our
automotive customers, increases in our raw material and energy costs, labor costs and strikes at our
major direct and indirect customers and at our facilities, dependence on significant automotive
customers, the level of competition in the automotive supply industry and pricing pressures from our
customers, technological developments that could competitively disadvantage us, and risks
associated with conducting business in foreign countries. In addition, factors more specific to us could
cause actual results to vary materially from those anticipated in the forward-looking statements
included in this report such as substantial leverage, limitations imposed by our debt instruments, the
adequacy of our liquidity to meet our capital expenditures and other cash requirements, our ability to
identify attractive and other strategic opportunities and to successfully integrate acquired businesses
including actions we have identified as providing cost-saving opportunities. We do not undertake any
obligation to review or confirm analysts' expectations or estimates or to release publicly any revisions
to any forward-looking statements to reflect events or circumstances after the date of this report or to
reflect the occurrence of unanticipated events.

Approximately $0.6M of Sarbanes Oxley costs

Q4 2005 Outlook as presented in 1/11/06 8K Filing

($ in 000s)

Q3 2004 EBITDA
contains a $4.5
million reduction
of management
incentive
compensation.

Q3 2005 Performance

(1) The Company defines Adjusted EBITDA as net income (loss) before cumulative effect of
accounting change and before interest, taxes, depreciation, amortization, asset impairment,
non-cash losses on sale-leaseback of and equipment and non-cash restricted stock award
expense. See reconcilation of Net Income to Adjusted EBITDA in the appendix.

(2) Note that the Company received approximately $19 million and $84 million in the third
quarter and the YTD third quarter of 2005 respectively in pricing related to material cost
increases for the components it manufactures. However, these cost increases were a direct
pass through to the customers and the Company did not make any margin on this price
increase. Adjusting sales to eliminate this price increase, margin would have been 0.3%
higher in the third quarter and 0.5% higher in the YTD third quarter of 2005.

(3) Restructuring expense mainly due to reduction in headcount in response to 2005 and 2004
economic conditions.
