In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments necessary to present fairly the financial position as of October 30, 1999, and the results of operations and the cash flows for the periods ended October 30, 1999, and October 24, 1998. Such adjustments are of a normal recurring nature. The results of operations for the quarter ended October 30, 1999, and October 24, 1998, are not necessarily indicative of the results to be expected for the full year. The balance sheet at April 24, 1999, is derived from the audited balance sheet as of that date. These financial statements should be read in conjunction with the financial statements included in the 1999 Annual Report on Form 10-K filed on July 19, 1999. 2. The fiscal year end of the Company is the last Saturday in April. The second quarter of fiscal year 2000 and 1999 represent the 13 weeks ended October 30, 1999 and October 24, 1998, respectively. The first six months of fiscal year 2000 include 27 weeks while the first six months of fiscal year 1999 include 26 weeks. 3. Cash equivalents consist of investments in money market funds, highly rated commercial paper and government securities. The maturities of these securities at the time of purchase is 90 days or less. Short-term investments consist of highly rated commercial paper and government securities with maturities longer than 90 days at the date of purchase. All cash equivalents and short-term investments are classified as available for sale and cost approximates market value. 4. The Company made the following acquisitions that affect the periods covered by these financial statements: Dentaplex, Inc. July 27, 1998 J&S Dental Supply Company, Inc. February 9, 1999 Barr Dental Supply, Inc. June 28, 1999 Kentucky Dental Supply Company, Inc. October 25, 1999 These acquisitions were accounted for as purchases and, accordingly, the net assets and operating results are included in the Company's financial statements from the date of acquisition. The results of operations of these acquisitions individually, and in the aggregate, were not material to the financial statements on a pro forma basis. 5. On February 5, 1999, the Company acquired Professional Business Systems, Inc. in exchange for 214,317 shares of common stock. The acquisition was accounted for as a pooling-of-interests and was not material to the financial statements on a pro forma basis. The financial statements have not been restated to reflect the financial position and results of the operations prior to the date of acquisition based on materiality. 6 7. The following table sets forth the denominator for the computation of basic and diluted earnings per share: Three Months Ended Six Months Ended ------------------ ------------------- Oct. 30, Oct. 24, Oct. 30, Oct. 24, 1999 1998 1999 1998 ------ ------ ------ ------ Denominator: Denominator for basic earnings per share - weighted-average shares 33,676 33,323 33,665 33,307 Effect of dilutive securities: Director Stock Option Plan 69 53 61 55 Employee Stock Purchase Plan 5 5 5 5 Capital Accumulation Plan 58 56 46 45 ------ ------ ------ ------ Dilutive potential common shares 132 114 112 105 ------ ------ ------ ------ Denominator for diluted earnings per share - adjusted weighted-average shares and assumed conversions 33,808 33,437 33,777 33,412 ====== ====== ====== ====== 7 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS RESULTS OF OPERATIONS The following table sets forth, for the periods indicated, the percentage of net sales represented by certain operational data. Three Months Ended Six Months Ended ------------------ ---------------- Oct. 30, Oct. 24, Oct. 30, Oct. 24, 1999 1998 1999 1998 ----- ----- ----- ----- Net sales...................... 100.0% 100.0% 100.0% 100.0% Cost of sales.................. 63.4% 63.0% 63.4% 63.1% ----- ----- ----- ----- Gross profit................... 36.6% 37.0% 36.6% 36.9% Operating expenses............. 27.6% 28.2% 27.8% 28.5% ----- ----- ----- ----- Operating income............... 9.0% 8.8% 8.8% 8.4% Other income and expense, net.. 0.5% 0.1% 0.5% 0.2% ----- ----- ----- ----- Income before income taxes..... 9.5% 8.9% 9.3% 8.6% Income taxes................... 3.5% 3.3% 3.5% 3.2% ----- ----- ----- ----- Net income..................... 6.0% 5.6% 5.8% 5.4% ===== ===== ===== ===== QUARTER ENDED OCTOBER 30, 1999 COMPARED TO QUARTER ENDED OCTOBER 24, 1998. Net Sales. Net sales increased 16.5% to $248.4 million for the three months ended October 30, 1999 ("Current Quarter") from $213.3 million for the three months ended October 24, 1998 ("Prior Quarter"). All product categories contributed to the sales increase. Sales of dental sundry products increased 16.4% due primarily to an increase in the customer base and a 10 percent year-to-year increase in the sales force. Equipment sales increased 14.2%. Sales of Colwell printed office products were up 32.2%, which included the February 1999 acquisition of Professional Business Systems ("PBS"). Excluding the impact of PBS, sales were up 7.6%. EagleSoft software and related product sales were up 37.9% as customers upgraded their systems to be year 2000 compliant. Sales in Canada improved 14.2%, benefiting from an improving economy. Gross Profit. Gross profit margin declined to 36.6% for the Current Quarter from 37.0% for the Prior Quarter. The 40 basis point gross margin decrease was due primarily to the absence of certain buying opportunities that were available last year. Gross profit increased 15.0% to $90.8 million for the Current Quarter from $78.9 million for the Prior Quarter. The majority of the increase in gross profit was due to increased sales. 8 Operating Expenses. Operating expenses increased 13.7% to $68.5 million for the Current Quarter from $60.2 million for the Prior Quarter. The increase in operating expenses was principally related to the higher sales volume and increased health care costs. Operating expenses as a percent of sales, however, decreased from 28.2% in the Prior Quarter to 27.6% in the Current Quarter. Operating Income. Operating income increased 19.5% to $22.3 million for the Current Quarter from $18.7 million for the Prior Quarter. Operating income as a percent of net sales increased from 8.8% to 9.0%, due to improved operating leverage. Finance Income. Finance income, net of expenses, was $1.1 million for the Current Quarter compared to $.4 million for the Prior Quarter. Finance income increased $.8 million due primarily to higher average short-term investments of cash. Income Taxes. The effective income tax rate decreased slightly to 37.4% for the Current Quarter from 37.6% for the Prior Quarter. Net Income. Net income was $14.8 million, up $2.9 million or 24.5% from $11.9 million reported in the second quarter of last year due to the factors discussed above. Earnings Per Share. Earnings per share were 44 cents which represents an 8 cent or 22.2% increase over the same quarter a year ago. SIX MONTHS ENDED OCTOBER 30, 1999 COMPARED TO SIX MONTHS ENDED OCTOBER 24, 1998. Net Sales. Net sales increased 21.7% to $503.0 million for the six months ended October 30, 1999 ("Current Period") from $413.4 million for the six months ended October 24, 1998 ("Prior Period"). The Current Period includes 27 weeks versus 26 weeks in the Prior Period. Excluding the impact of the additional week, sales increased approximately 17%. Sales references in parentheses exclude the additional week. Sales of sundries increased 21.0%(17%) due primarily to contributions from an expanded sales force and an increase in number of customers. Equipment sales increased 20.8%(16%) on strong demand across the line. Sales of printed office products through Colwell Systems were up 36.0%. Excluding the impact of the acquisition of PBS and the additional week sales increased 6.6%. An expanded product offering and better account penetration by the dental sales force were the major factors contributing to the increase. EagleSoft software and related services sales increased 64.6%(58%). Gross Profit. Gross profit margin decreased to 36.6% for the Current Period from 36.9% for the Prior Period due primarily to the absence of certain buying opportunities that were available last year. Gross profit increased 20.9% to $184.3 million for the Current Period from $152.5 million for the Prior Period. The increase in gross profit was due primarily to the increase in sales volume. Operating Expenses. Operating expenses increased 18.9% to $139.9 million for the Current Period from $117.6 million for the Prior Period. The majority of the increase in operating expenses was related to greater sales volume, incentive compensation and higher health care costs. Operating expenses as a percent of sales declined from 28.5% to 27.8% due to improved operating leverage. 9 Operating Income. Operating income increased 27.3% to $44.5 million for the Current Period from $34.9 million for the Prior Period. As a percent of net sales, operating income increased from 8.4% to 8.8%, due to better leverage of the Company's infrastructure. Finance Income. Finance income, net of expenses, was $2.0 million for the Current Period compared to $.8 million for the Prior Period. Finance income increased $1.2 million due primarily to increased average short-term investments of cash. Income Taxes. The effective income tax rate decreased to 37.4% for the Current Period from 38.1% for the Prior Period as a result of operating profit in Canada and utilization of tax-loss carryforwards in that country. Net Income. Net income was $29.3 million, up $7.2 million or 32.4 % from $22.1 million reported in the first half of last year due to the factors discussed above. Earnings Per Share. Earnings per share were 87 cents which represents a 21 cent or 31.8% increase over the same period a year ago. LIQUIDITY AND CAPITAL RESOURCES Available liquid resources at October 30, 1999 consisted of $90.8 million of cash and short-term investments and $11.3 million available under existing bank lines at October 30, 1999. Inventory increased $14.9 million from the beginning of the fiscal year. However, inventory turnover increased from 6.0 at the beginning of fiscal year 2000 to 6.2 turns at October 30, 1999. Accounts receivable increased $1.9 million to $106.6 million from the beginning of the year, while days sales outstanding declined to 41 days from 43 days. Capital expenditures increased $3.8 million in the Current Period versus the Prior Period as the Company invested in a new distribution center that is expected to come on line in February 2000. The Company believes that cash and short-term investments and the remainder of its credit lines are sufficient to meet any existing and presently anticipated cash needs. In addition, because of its low debt to equity ratio, the Company believes it has sufficient debt capacity to replace its existing revolver and provide the necessary funds to achieve its corporate objectives. IMPACT OF YEAR 2000 The Year 2000 issue is the result of the widespread use of computer programs which were written using two digits rather than four to define the applicable year in performing computations or decision-making functions. The Company has completed its assessment of its major information technology and technology reliant operating systems, including its internal accounting, general ledger, billing, inventory and accounts payable systems. Necessary modifications or replacements of existing systems, including testing of these systems, have been completed. The Company has also assessed the need for modifications or replacements of existing hardware, particularly personal computers, and has completed this assessment phase. The remediation and testing of existing hardware has been completed. As a result, the Company believes that substantially all critical business systems and hardware are Year 2000 compliant. The Company has been implementing the necessary modifications and replacements of its operating systems in the ordinary course of its business over 10 the last four years and believes the incremental costs to complete this program were less than $200,000. Over the past four years the Company has invested approximately $500,000 in new systems. The Company is also dependent on its vendors to supply the products it sells and on service providers, including transportation providers and utilities. The Company has sought assurances from its significant suppliers of products and services to determine the impact on the Company if such suppliers fail to convert their computer systems. While the vast majority of the Company's significant suppliers have assured the Company that their systems are currently Year 2000 compliant, or will be made Year 2000 compliant prior to December 31, 1999, there can be no assurance that there will not be a material adverse impact on the Company if a substantial number of significant suppliers fail to convert their systems. The Year 2000 efforts of third parties are ultimately beyond the Company's control. The risk to the Company if significant product vendors fail to convert their computer systems and, as a result, are unable to ship products to the Company in a timely manner after the year 2000 is that the Company may not be able to offer such products to its customers and will be able to offer only replacement products, if available. The Company generally has more than one source of supply for almost all categories of products it sells. The risks to the Company if significant service providers fail to timely convert their computer systems may include, in the case of vital utility services, the inability of a branch office or distribution center to operate. In such an event, the Company does have the ability to shift its distribution and branch office operations to other distribution centers and branches within its system. However, notwithstanding the Company's efforts to substitute products or shift distribution or branch operations, the inability of significant suppliers of products and services to complete their Year 2000 resolution process in a timely fashion could materially adversely affect the Company. The amount of lost revenue and the impact on the Company can not be reasonably estimated at this time. The Company has developed contingency plans in the event significant suppliers of products or services fail to complete their Year 2000 resolution process. These plans include identifying alternate sources of products, increasing the inventory of certain products, testing the operation of critical systems at each location during the holiday week-end, preparing to shift operations from any branch or distribution center location which fails to operate to other branches or distribution centers which are operational, and temporarily redirecting staff to certain customer service functions to help resolve Year 2000 issues which may arise. The Company believes it has an effective program in place to resolve the Year 2000 issue in a timely manner. As noted above, the failure of significant suppliers of products and services to the Company to resolve their own Year 2000 issues could materially adversely affect the Company. In addition, disruptions in the economy generally as a result of Year 2000 issues also could materially adversely affect the Company. The foregoing discussion regarding Year 2000, including the discussion of the timing and effectiveness of the Company's Year 2000 remediation efforts, contains forward-looking statements which are based on management's best estimates derived using assumptions and information considered reasonable. These forward-looking statements involve inherent risks and uncertainties, and actual results could differ materially from those contemplated by such statements. Factors that might cause material differences include, but are not limited to, the Company's ability to locate and correct all relevant Year 2000 computer code and the ability of significant suppliers of products and services to effectively address the Year 2000 issue. Such material differences could result in business disruption, operational problems, and similar risks. 11 FACTORS THAT MAY AFFECT FUTURE OPERATING RESULTS Certain information of a non-historical nature contain forward-looking statements. Words such as "believes", "expects", "plans", "estimates" and variations of such words are intended to identify such forward-looking statements. The statements are not guaranties of future performance and are subject to certain risks, uncertainties or assumptions that are difficult to predict: therefore, the Company cautions shareholders and prospective investors that the following important factors, among others, could in the future affect the Company's actual operating results which could differ materially from those expressed in any forward-looking statements. The statements under this caption are intended to serve as cautionary statements within the meaning of the Private Securities Litigation Reform Act of 1995. The following information is not intended to limit in any way the characterization of other statements or information under other captions as cautionary statements for such purpose. The order in which such factors appear below should not be construed to indicate their relative importance or priority. o Reduced growth in expenditures for dental services by private dental insurance plans. o Accuracy of the Company's assumptions concerning future per capita expenditures for dental services, including assumptions as to population growth and the demand for preventive dental services such as periodontic, endodontic and orthodontic procedures. o The rate of growth in demand for infection control products currently used for prevention of the spread of communicable diseases such as AIDS, hepatitis and herpes. o The effects of health care reform, increasing emphasis on controlling health care costs and legislation or regulation of health care pricing, all of which may affect the ability of dentists to obtain reimbursement for use of new and state-of-the-art procedures and technologies. o The amount and growth of the Company's selling, general and administrative expenses. o The effects of, and changes in, U.S. and world social and economic conditions, monetary and fiscal conditions, laws and regulations, other activities of governments, agencies and similar organizations, trade policies and taxes, import and other charges, inflation and monetary fluctuations; the ability or inability of the Company to obtain or hedge against foreign currencies, foreign exchange rates and fluctuations in those rates. o Ability of the Company to retain its base of customers and to increase its market share. o The ability of the Company to maintain satisfactory relationships with qualified and motivated sales personnel. o Changes in economics of dentistry affecting dental practice growth and the demand for dental products, including the ability and willingness of dentists to invest in high-technology diagnostic and therapeutic products. o The Company's ability to meet increased competition from national, regional and local full-service distributors and mail-order distributors of dental products, while maintaining current or improved profit margins. 12 o Continued ability of the Company to maintain satisfactory relationships with key vendors and the ability of the Company to create relationships with additional manufacturers of quality, innovative products. o The ability of the Company and its suppliers to upgrade their computer systems to adequately address the Year 2000 issue. o Future operating results of the Company's printed office products group depends upon its ability to attract and retain customers by offering quick response time and innovative products that meet industry reporting standards. Because the cost of paper stock represents over half the cost of its paper and printed products, future operating results may be subject to fluctuations in paper prices. In addition, the introduction of computer-based technologies into the management of health care practices may affect future demand for printed products. 13 PART II OTHER INFORMATION Item 4.
