Park-Ohio Reports Increased Revenue and Income in First Quarter 2006

• Sales up 14%

• Pretax Income up 11%

     CLEVELAND, OHIO, May 5, 2006 — Park-Ohio Holdings Corp. (NASDAQ:PKOH) today announced results for its first quarter ended March 31, 2006.

     Park-Ohio reported net sales of $260.2 million for first quarter 2006, a 14% increase on sales of $228.9 million for first quarter 2005.

     Park-Ohio reported income before income taxes of $7.8 million for first quarter 2006, an 11% increase on income before income taxes of $7.0 million for first quarter 2005. Park-Ohio recorded income tax expense of $3.0 million for first quarter 2006, an effective income tax rate of 39%, compared to $.8 million, or an effective income tax rate of 11% for first quarter 2005. No federal income taxes were expensed for first quarter 2005 due to the Company’s tax valuation allowance, which was reversed at the end of 2005. Park-Ohio reported net income of $4.8 million, or $.42 per share dilutive, for first quarter 2006, which included the impact of federal income tax expense. This compared to net income of $6.2 million, or $.54 per share dilutive, for first quarter 2005, which benefited from the absence of federal income tax expense. If federal income taxes had been recorded for first quarter 2005, Park-Ohio would have reported net income fully taxed^(A) of $4.3 million, or $.38 per share dilutive.

     Edward F. Crawford, Chairman and Chief Executive Officer, stated, “We are pleased with our continued trend of significant global growth in revenue and profitability. Our first quarter sales of more than $260 million included strong new business activity at ILS and in our businesses which support the oil and gas industries. We are comfortable in reaffirming our guidance of revenues of $1.0 to $1.05 billion and EPS of $1.65 to $1.75 for 2006.”

     A conference call reviewing Park-Ohio’s first quarter results will be broadcast live over the Internet on Monday, May 8, commencing at 11:00 am Eastern Time. Simply log on to http://www.pkoh.com.

     Park-Ohio is a leading provider of supply chain logistics services and a manufacturer of highly engineered products. Headquartered in Cleveland, Ohio, the Company operates 24 manufacturing sites and 40 supply chain logistics facilities.

     In fourth quarter 2005, the Company reversed $7.3 million of its domestic deferred tax asset valuation allowance, increasing net income. In 2006, the Company began recording a quarterly provision for federal income taxes, which resulted in a total effective income tax rate of approximately 39%. Park-Ohio’s significant net operating loss carryforward should preclude the payment of cash federal income taxes in 2006 and substantially reduce cash payments in 2007. In fourth quarter 2006, if a portion or all of its remaining deferred tax asset will more likely than not be realized, the Company will reverse into income the appropriate portion of its remaining tax valuation allowance of approximately $5.0 million.

Note A—In 2006, the Company began recording a quarterly provision for federal income taxes resulting in a total effective income tax rate of approximately 39 percent. The Company’s significant net operating loss carryforwards should preclude the cash payment of federal income taxes in 2006. In the fourth quarter of 2006, if a portion or all of its remaining deferred tax asset will more likely than not be realized, the Company will reverse into income the appropriate portion of its remaining tax valuation allowance of approximately $5.0 million.

Note B—EBITDA, as defined, reflects earnings before interest and income taxes, and excludes depreciation, amortization, certain non-cash charges and corporate-level expenses as defined in the Company’s revolving credit agreement. EBITDA is not a measure of performance under generally accepted accounting principles (“GAAP”) and should not be considered in isolation or as a substitute for net income, cash flows from operating, investing and financing activities and other income or cash flow statement data prepared in accordance with GAAP or as a measure of profitability or liquidity. The Company presents EBITDA because management believes that EBITDA is useful to investors as an indication of the Company’s satisfaction of its Debt Service Ratio covenant in its revolving credit agreement and because EBITDA is a measure used under the Company’s revolving credit facility to determine whether the Company may incur additional debt under such facility. EBITDA as defined herein may not be comparable to other similarly titled measures of other companies. The following table reconciles net income to EBITDA, as defined:
