FISCAL 2006 SECOND QUARTER RESULTS

— Sales increase 12.7% to $305.9 million —

— Earnings per diluted share increase 26% to $0.49 —

Melville, NY, March 30, 2006 - MSC INDUSTRIAL DIRECT CO., INC. (NYSE: MSM), “MSC or the Company” one of the premier distributors of MRO supplies to industrial customers throughout the United States, today reported financial results for its fiscal 2006 second quarter ended February 25, 2006.

Net sales for the second quarter of fiscal 2006 rose 12.7% to $305.9 million from $271.4 million in the fiscal 2005 second quarter. Net income for the fiscal 2006 second quarter rose 21.6% to $33.3 million versus $27.4 million in the year-ago period. Fiscal 2006 second quarter diluted earnings per share increased 25.6% to $0.49, compared with diluted earnings per share of $0.39 in the second quarter of fiscal 2005. The Company’s results for the second quarter of fiscal 2006 include a charge of $0.01 per diluted share for the costs associated with the departure of an executive and a charge of $0.02 per diluted share related to the expensing of stock options as required by SFAS 123R. These charges were not present in the Company’s fiscal 2005 second quarter results.

For the first half of fiscal 2006, the Company’s net sales rose 12.6% to $601.8 million, compared to net sales of $534.7 million a year ago. Net income in the fiscal 2006 six-month period was $65.3 million, or $0.96 per diluted share, compared to $53.4 million, or $0.75 per diluted share, in the year ago period, an increase of 22.2% in net income and 28% in diluted earnings per share. Included in the Company’s results for the first six months of fiscal 2006 are charges totaling $0.05 per diluted share related to the expensing of stock options as required by SFAS 123R, as well as $0.01 per diluted share for costs related to the departure of an executive.

“We are very pleased with the results for the second quarter of fiscal 2006,” stated David Sandler, President and Chief Executive Officer. “Successful execution on our strategy and delivery of our value proposition to customers, allowed us to continue to gain share and grow in all of our markets, resulting in revenue growth of 12.7% in the quarter and financial performance that exceeded our original expectations. We saw balanced growth throughout our geographic regions, as well as between the manufacturing and non-manufacturing sectors of our business. Importantly, we continued to improve our profitability during the second quarter, expanding our income from operations to 17.7% of sales

from 16.2% a year ago and substantially growing our earnings per share. All of these achievements were made while continuing to invest in our market expansion strategy, a clear sign of the leverage we have built into our business model.”

“Financially, the fiscal 2006 second quarter was another strong one for MSC,” said Chuck Boehlke, Executive Vice President and Chief Financial Officer. “Our continued focus on cost management combined with the growth we attained on the top line enabled us to convert 38% of incremental sales into operating income, excluding the additional operating costs related to SFAS 123R and the departure of an executive. We also continued our strong cash flow performance, generating $6.8 million in free cash flow (see Note 1) during the second quarter of fiscal 2006, compared with $1.3 million in free cash flow a year ago. Our excellent financial performance puts MSC in a strong position to continue executing on its strategy and investing in its future.”

As previously announced, the Company has signed a definitive agreement to acquire J & L America, Inc. DBA as J & L Industrial Supply (J & L), a subsidiary of Kennametal Inc., for $349.5 million. J & L is a leading national specialty metalcutting and finishing distributor with over 74,000 customers and an industry-leading offering of many of the top brands in metalworking. The transaction is expected to close during the second calendar quarter of 2006, subject to customary closing conditions.

Mr. Sandler concluded, “Looking forward, we are extremely excited about our future. Market conditions remain solid, and our core business continues to show strength and grow. We look forward to the successful completion of the J & L acquisition, and to realizing the significant benefits built into this strategic transaction, while also continuing our market expansion strategy. Overall, we remain confident in our ability to take market share and create value for our associates, customers, owners, and suppliers. Based on current market conditions, and without taking into account the J & L transaction, we expect net sales for the fiscal 2006 third quarter to be between $323.0 million and $327.0 million, and diluted earnings per share of between $0.52 and $0.54, which includes approximately $0.02 per diluted share related to the expensing of stock options.”

The management of MSC will host a conference call today at 11:00 a.m. Eastern Time to review the second quarter of fiscal 2006 results and to comment on current operations. The call may be accessed via the Internet at: http://www.mscdirect.com.

Note 1 – Free cash flow is defined as net cash provided by operating activities less expenditures for property, plant and equipment. Net cash flow provided by operating activities during the fiscal 2006 second quarter was $12.1 million. Expenditures for property, plant and equipment in the fiscal 2006 second quarter were $5.3 million. Management considers free cash flow to be an important indicator of the Company’s financial strength and the ability to generate liquidity because it reflects cash generated from operations that can be used for strategic initiatives, dividends, and repurchases of the Company’s stock.

MSC distributes more than 500,000 industrial products from approximately 2,100 suppliers to approximately 344,000 customers.
