Short Hills, NJ —October 20, 2004 — D&B (NYSE: DNB), the leading provider of global business information, tools, and insight today reported results for the third quarter ended September 30, 2004.

“As we continue to transform D&B, this quarter’s progress clearly demonstrates that our Blueprint for Growth strategy is working,” said Allan Loren, chairman and chief executive officer of D&B. “By focusing on improving our leadership, and in particular leading through change, we have been able to continually meet our shareholder commitments. The progress we experienced this quarter was made possible by the dedication of our team members worldwide who are committed to creating value for customers and shareholders alike.”

The Company reported diluted earnings per share for the quarter, before non-core gains and charges, of 65 cents, up 20 percent from 54 cents in the prior year quarter. On a GAAP basis, diluted earnings per share were 65 cents, up 71 percent from 38 cents in the prior year quarter. See attached Schedule 3 for a reconciliation of earnings per share before non-core gains and charges to earnings per share on a GAAP basis.

Core revenuefor the quarter was $333.2 million, a 9 percent increase compared with the prior year quarter. Core revenue was up 8 percent before the effect of foreign exchange with all of the increase due to organic growth.

“Our DUNSRight™ quality process, which powers our portfolio of customer solution sets, provides our customers with unparalleled business insight, so they can make confident business decisions,” said Steve Alesio, president and chief operating officer. “The power of DUNSRight™ combined with our team members’ leadership enabled us to deliver our fifth consecutive quarter of organic revenue growth.”

Core revenue results reflected the following by product line:

• Risk Management Solutions revenue of $226.5 million, up 8 percent
(up 6 percent before the effect of foreign exchange);

• Sales & Marketing Solutions revenue of $84.9 million, up 9 percent

Operating incomefor the third quarter was $75.6 million, up 9 percent from the year ago period, before non-core charges in both years. Both the North America and International segments contributed to the growth in operating income. These increases were partially off-set by investments in both re-engineering and Sarbanes-Oxley requirements.

See attached Schedule 3 for a reconciliation of net income before non-core gains and charges to net income on a GAAP basis.

Free cash flowfor the first nine months of 2004 was $154.7 million, up 13 percent from the first nine months of 2003. Net cash flow provided by operating activities was $174.3 million for the first nine months of 2004, up 12 percent.

The Company ended the quarter with $193.8 million of cash and cash equivalents. See attached Schedule 4 for a reconciliation of free cash flow to net cash provided by operating activities.

D&B 4/10

Total revenuefor the quarter was $85.4 million, a 17 percent decrease from total revenue in the prior year quarter (down 23 percent before the effect of foreign exchange). Third quarter 2003 revenue included $27.9 million of revenue from businesses that were divested over the past year.

Operating incomefor the quarter was $12.1 million, up 13 percent from $10.8 million in the prior year quarter. This improvement in profitability was primarily due to a lower expense base associated with the Company’s Financial Flexibility program.

Financial Flexibility Initiatives

The Company continues to leverage its financially flexible business model to fund investments for growth and to create shareholder value through its process of continuous reengineering.

In April of this year, the Company outlined its financial flexibility initiatives for 2004. At that time, the Company announced that on an annualized basis, the financial flexibility initiatives for 2004 are expected to create approximately $80 million of savings, of which approximately $50 million will be generated this year. To implement these initiatives, the Company expects to incur transition costs of approximately $22 million. In addition, the Company expects to incur non-core charges totaling approximately $30 to $35 million pre-tax, primarily for severance and termination costs in 2004.

In conjunction with these initiatives, the Company announced today plans to outsource certain portions of its data acquisition and delivery, customer service, and financial processes to International Business Machines Corporation (IBM). By establishing this relationship with IBM, the Company expects to:

• Enhance its DUNSRight™ quality process,

• Improve the level of service it provides to customers, and

• Reduce the costs associated with these functions.

As a result of this decision, the Company expects 750 positions globally to be eliminated, of which approximately 220 team members will transfer to IBM and will

D&B 5/10

be placed there for at least one year, with the opportunity to pursue available positions within IBM.

Team members not transferring to IBM will continue in their roles with D&B for a period of approximately three to six months. The Company will provide a severance and benefits package, and professional and personal support through on-site outplacement services as they transition out of the business, or work with them to explore other opportunities within D&B.

"Continuous reengineering is an integral part of our financially flexible business model, which enables us to invest for growth and create shareholder value,” said Loren. “While these initiatives will improve the performance of our business, we recognize this means change for our team members and we are committed to providing them with the help and support they need during the transition.”

For a more detailed discussion of this outsourcing plan, please see the Company’s Form 8K, filed today with the Securities and Exchange Commission.

Non-Core Gains and Charges

During the quarter, the Company recorded net pre-tax, non-core charges of $1.9 million as compared to net pre-tax non-core charges of $15.4 million in the third quarter of 2003.

The net, non-core charges in the third quarter of 2004 included a pre-tax, non-core charge of $2.7 million related to its financial flexibility initiatives in the third quarter of 2004, which was recorded within operating income as Corporate and other expense, and a pre-tax, non-core gain of $0.8 million, within Non-Operating Income (Expense)-Net, to reduce the second quarter of 2004 impairment charge, reflecting the fair market value of the Company’s Iberian operations at the end of the third quarter.

In the third quarter of 2003, the Company recorded pre-tax, non-core charges of $1.6 million related to the fourth phase of its financial flexibility initiatives and a $13.8 million non-core charge related to the monetization of real estate. The charges were recorded within operating income as corporate and other expense.

D&B’s restructuring charges may be viewed as recurring as they are part of each phase of its financial flexibility initiatives. In addition to reporting GAAP results, the

D&B 6/10

Company reports results before restructuring charges and other non-core gains and charges because they are not a component of its ongoing income or expense and may have a disproportional positive or negative impact on the results of its ongoing underlying business operations. See section entitled “Use of Non-GAAP Financial Measures”.

Confirms Full Year 2004 Outlook

The Company confirmed the following guidance:

• Full year diluted EPS of $2.81 to $2.91 on a GAAP basis, up 22 percent-27 percent,

• Full year diluted EPS of $2.94 to $2.99, up 16 percent -18 percent before non-core gains and charges of $0.08 to $0.13,

• Core revenue growth of 6 percent-8 percent, before the effect of foreign exchange,

• The Company does not provide revenue growth guidance on a GAAP basis because D&B is unable to predict the future movement of foreign exchange rates,

• Free cash flow of $230 to $245 million, before any final settlement of tax matters discussed in the Company’s second quarter Form 10Q.

Use of Non-GAAP Financial Measures

D&B reports non-GAAP financial measures in this press release and the Schedules attached. D&B reports core revenue and core revenue growth before the effects of foreign exchange, organic revenue growth and each of operating income, net income and diluted earnings per share before non-core gains and charges, and free cash flow. Please see the Company’s Form 8-K filed July 19, 2004 with the Securities and Exchange Commission for a discussion of how the Company defines these measures, why it uses them and why it believes they provide useful information to investors.

Forward-Looking and Cautionary Statements

The section entitled “Full Year 2004 Outlook” of this press release contains projections of future results and other forward-looking statements that involve a number of trends, risks and uncertainties and are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. The following important factors could cause actual results to differ materially from those projected in such forward-looking statements.

D&B 8/10

Demand for D&B’s products is subject to intense competition, changes in customer preferences and, to a lesser extent, economic conditions which impact customer behavior. The Company’s results are also dependent upon its continued ability to:

• reallocate expenses to invest for growth through its financial flexibility program;

• accurately forecast cost increases associated with increasing revenue growth;

• accurately forecast the cost of increasing regulatory requirements, such as Sarbanes-Oxley requirements;

• invest in its database and maintain its reputation for providing reliable data;

• execute on its plan to improve the business model of its International segment and thereby improve its global data quality while realizing improved financial performance in that segment;

• rely on its customers’ belief in the value of the DUNSRightTM quality process as a key driver of revenue growth;

• manage employee satisfaction and maintain its global expertise as it implements its financial flexibility program;

• protect against damage or interruptions affecting its database or its data centers; and

• develop new products or enhance existing ones to meet customer needs.

The Company is also subject to the effects of foreign economies, exchange rate fluctuations and U.S. and foreign legislative or regulatory requirements. Its results are also dependent upon the availability of data from its database and the ability of its strategic partners to fulfill their contractual obligations to satisfy the Company’s customers and promote and protect the D&B brand. In addition, the Company’s ability to repurchase shares is subject to market conditions, including trading volume in the Company’s stock. Developments in any of these areas could cause actual results to differ materially from those that have been or may be projected. The Company’s projection for free cash flow in 2004 is dependent upon the Company’s ability to generate revenue, the Company’s collection processes, customer payment patterns and the amount and timing of payments related to tax matters and legal proceedings involving the Company as more fully described in the Company’s filings with the SEC.

D&B 9/10

For a more detailed discussion of the trends, risks and uncertainties that may affect D&B’s operating and financial results and its ability to achieve the financial objectives discussed in this press release, readers should review the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2003, including the section entitled “Item 7.
