St. Paul, Minn. — Deluxe Corporation (NYSE: DLX), the nation’s leading check printing company, reported third quarter diluted earnings per share (EPS) of $1.09 on net income of $58.2 million. Diluted earnings per share and net income for the third quarter in 2002 were $.83 and $52.7 million, respectively.

“As expected, new business gains resulted in improved unit volume in the third quarter as compared to the first half of 2003,” said Lawrence J. Mosner, chairman and CEO of Deluxe Corporation. “At the same time, increased competitive pricing negatively impacted our revenue per unit. We did, however, continue to manage costs aggressively which resulted in an improvement in operating income for the third quarter.”

Third Quarter Performance
Deluxe’s third quarter net income was $58.2 million, compared to $52.7 million during the same quarter in 2002. EPS was $1.09 per diluted share compared to $.83 for the same period a year ago. EPS was positively impacted $.02 due to share repurchase activity since June 30, 2003, and $.17 due to the net impact of share repurchases made during the past 12 months. Additionally, third quarter results were positively impacted by $7.3 million due to the expiration of certain income tax periods and completion of tax audits.

Revenue decreased 1.5 percent to $314.9 million in the third quarter, from $319.8 million during the same quarter a year ago. The decrease in revenue was due to a 0.9 percent decline in revenue per unit and a 0.6 percent decline in unit volume.

Gross margin was 66.3 percent of revenue for the quarter, the same as in 2002. The lower unit volume and revenue per unit were offset by productivity improvements and cost management.

Selling, general and administrative expense (SG&A) as a percentage of revenue was 38.4 percent, compared to 39.0 percent in 2002. SG&A declined $3.9 million for the quarter, primarily due to lower employee costs and discretionary spending in response to the challenging business and economic environments.

As a result, operating income increased 1.4 percent to $87.7 million in the third quarter, from $86.5 million last year. Operating margin improved to 27.9 percent of revenue, compared to 27.1 percent last year.

Interest expense increased to $4.9 million for the quarter, compared to $1.2 million in 2002, due to higher interest rates and debt levels. The majority of the increase in interest expense was due to the December 2002 issuance of $300.0 million of 10-year senior, unsecured notes with an interest rate of 5.0 percent. Also, in September 2003, the Company issued $50.0 million of medium-term notes that will mature in September 2006 at an interest rate of 2.75 percent.

Year-to-Date Performance
For the first nine months of 2003, net income decreased 5.4 percent to $153.1 million, compared to net income of $161.9 million during the same period a year ago. Earnings per share for the first nine months of 2003 increased to $2.71 diluted per share, compared to $2.53 diluted per share in 2002, due primarily to fewer shares outstanding.

Revenue was $941.6 million for the first nine months of the year, compared to $977.1 million a year ago. The 3.6 percent decrease in revenue was due to a unit decline of 4.7 percent, partially offset by an increase in revenue per unit of 1.1 percent.

Gross margin decreased to 65.7 percent of revenue for the first nine months of 2003, compared to 66.1 percent in 2002. The change was due to lower unit volume, partially offset by the increase in revenue per unit.

SG&A for the first nine months of 2003 was 39.1 percent of revenue, the same as the first nine months of 2002. SG&A declined $12.9 million, however, due to lower employee costs and discretionary spending in response to the current business environment and reduced advertising expense in our Direct Checks segment.

As a result, operating margin was 26.6 percent of revenue for the first nine months of the year, compared to 27.0 percent of revenue a year ago.

Interest expense increased to $14.2 million for the first nine months of the year, compared to $3.3 million in 2002 due to higher interest rates and debt levels.

Business Outlook
Deluxe indicated that it now anticipates fourth quarter diluted EPS to be in the range of $.72 to $.76 per share, and full-year results to reach approximately $3.45 per share. The fourth quarter estimate includes approximately $5 million of severance expense, but excludes the impact of additional share repurchases subsequent to September 30, 2003. This compares to EPS of $.84 and $3.36 for the fourth quarter and full year 2002, respectively.

“Our previous guidance was based on our intent to not only retain existing clients, but also aggressively acquire new business in our Financial Services segment by providing financial institutions with greater value,” said Mosner. “This desire to increase our share, along with the very successful introduction of DeluxeSelect^SM, caused competitors to defend their positions with aggressive pricing offers. As a result, product discounts have been rising, pressuring revenue per unit across the industry. Discounting accelerated as many accounts came up for

bid in a compressed timeframe, and suppliers began to renew contracts early to reduce potential future losses.” Mosner added, “The bidding process seemed to take on a momentum of its own.

“Therefore, we will increase our focus on what we do best—offer value-added products and services through customer-centric relationships, and pursue those clients who find value in this approach. Having the lowest price has never been what Deluxe is about. After all, we have the highest quality, broadest product offerings, and the best check management programs in the industry.”

Mosner concluded, “To better align our cost structure to the realities of the marketplace, we will continue to manage our costs aggressively. In fact, we will be consolidating two additional manufacturing plants and further reducing SG&A expense.”

Third Quarter Segment Performance
Deluxe operates three business segments: Financial Services, which sells checks, related products and check merchandising services to financial institutions; Direct Checks, which sells checks and related products directly to consumers through direct mail and the Internet; and Business Services, which sells checks, forms and related products to small businesses and home offices through financial institution referrals, business alliances and via direct mail and the Internet.

Financial Services’ revenue decreased 6.8 percent to $176.3 million for the quarter, from $189.2 million in 2002. Operating income for the quarter decreased 11.8 percent to $41.0 million, from $46.5 million in 2002. The decreases were primarily the result of the heightened pricing pressure discussed above.

Direct Checks’ revenue decreased 1.1 percent to $75.1 million for the quarter, from $75.9 million in 2002. Operating income for the quarter increased 12.1 percent to $24.1 million, from $21.5 million in 2002. Revenue decreased due to lower unit volume and operating income increased as a result of higher revenue per unit and productivity improvements.

Business Services’ revenue increased 16.1 percent to $63.5 million for the quarter, from $54.7 million in 2002. Operating income for the quarter increased 22.2 percent to $22.6 million, from $18.5 million in 2002. Revenue and operating income were favorably impacted by new business and increased revenue per unit.
