NOTES TO FINANCIAL STATEMENTS 1. The Company - The consolidated financial statements as of and for the three months ended March 31, 2000 and 1999 have been prepared by DIANON Systems, Inc. (the "Company") without audit. In the opinion of management, all adjustments necessary to present fairly the financial position, results of operations and cash flows for such periods have been made, and the interim accounting policies followed are in conformity with generally accepted accounting principles and are consistent with those applied for annual periods as described in the Company's annual report for the year ended December 31, 1999, previously filed on Form 10-K with the Securities and Exchange Commission (the "Annual Report"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been omitted. It is suggested that these consolidated financial statements be read in conjunction with the financial statements included in the Company's Annual Report for the year ended December 31, 1999. The results of operations for the three months ended March 31, 2000 and 1999 are not necessarily indicative of the operating results for the full years. 2. Acquisitions - Effective May 1, 1999, the Company acquired substantially all the assets of an outpatient OB/GYN laboratory with locations in Woodbury and New City, New York ("Kyto Meridien Diagnostics, L.L.C." or "KMD"). The acquisition price was approximately $13.0 million and was financed through a combination of available cash and drawdowns of the Company's credit line, as well as through the issuance of Common Stock. The purchase price was primarily allocated to customer lists ($7.5 million), goodwill ($5.6 million), lab and office equipment ($400,000), and client receivables ($400,000), partially offset by accrued liabilities ($930,000). The acquisition has been accounted for pursuant to the purchase method of accounting. Pro forma net revenue for the three months ended March 31, 1999, adjusted as if the acquisition of KMD had occurred January 1, 1999 approximates $18.6 million. Pro forma net income and earnings per share would not differ materially from reported amounts. 7 DIANON SYSTEMS, INC. NOTES TO FINANCIAL STATEMENTS 3. Earnings per share - Basic earnings per share have been computed based on the weighted average number of common shares outstanding during each year. Diluted earnings per share have been computed based on the weighted average number of common shares and common equivalent shares outstanding during each year. Common equivalent shares outstanding include the common equivalent shares calculated for warrants and stock options under the treasury stock method. Below is a reconciliation of the numerators and denominators of the basic and diluted earnings per share computations for the first quarter 2000 and 1999. FIRST QUARTER FIRST QUARTER 2000 1999 ------------- ------------- BASIC EARNING PER SHARE: Weighted-average number of common shares outstanding 7,040,376 6,533,757 DILUTIVE EFFECT OF: Stock options 556,633 182,704 ------------- ------------- DILUTED EARNINGS PER SHARE: Weighted-average number of common shares outstanding 7,597,009 6,716,461 ============= ============= NET INCOME $1,259,601 $872,843 ============= ============= BASIC EARNINGS PER SHARE $0.18 $0.13 ============= ============= DILUTED EARNINGS PER SHARE $0.17 $0.13 ============= ============= Options to purchase 1,000 shares of common stock at $18.75 per share were outstanding as of March 31, 2000 but were not included in the computation of diluted earnings per share because the options' exercise price was greater than the average market price of common shares. Options to purchase 297,456 shares of common stock at prices ranging from $8.125 to $12.25 per share were outstanding as of March 31, 1999 but were not included in the computation of diluted earnings per share because the options' exercise price was greater than the average market price of common shares. 8 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS THREE MONTHS ENDED MARCH 31, 2000 AND 1999 (UNAUDITED) The descriptive analysis contained herein compares the financial results of the three months ended March 31, 2000 ("First Quarter 2000") to the three months ended March 31, 1999 ("First Quarter 1999"). The Company's results of operations in the First Quarter 2000 reflect favorable volume and mix increases in certain product lines, continued reductions in selling, general, administrative and other operating expenses, as a percentage of sales, and the acquisition of Kyto Meridien Diagnostics, L.L.C. ("KMD") in May 1999. RESULTS OF OPERATIONS - --------------------- o NET REVENUES Net revenues increased 39% to $22.1 million in the First Quarter 2000 from $15.9 million in the First Quarter 1999. This increase reflects the acquisition of KMD in May of 1999, volume increases in certain product lines, the successful negotiation and introduction in 1999 of several capitated contracts, and the effects of an increase in Medicare reimbursement for certain of the Company's tests. The clinical laboratory industry, which includes both clinical chemistry and anatomic pathology, has seen steady and continuing downward pressure on prices exerted by both government and private third-party payers. Payment for services such as those provided by the Company is and will likely continue to be affected by periodic reevaluations made by payers concerning which services to reimburse or cease reimbursing. Over time, Congress has reduced the national cap on Medicare laboratory fee schedules (under which the Company's clinical chemistry services are reimbursed) to 74% of the national median. In addition, the Balanced Budget Act of 1997 ("BBA") freezes fee schedule payments (i.e., no updates) for the 1998-2002 period. The President's fiscal year 2001 budget proposes to limit the Medicare laboratory fee schedule update to the Consumer Price Index minus 1%. The budget proposal also would reduce lab payments by 30% for four specific lab tests which the Administration claims Medicare pays significantly more for than the private sector. The four tests include two tests that are performed by the Company: prostate-specific antigen and bacterial urine culture. If adopted, this reduction in payments could have an adverse impact on the Company's revenues. In addition, as in past years, the President's budget proposes to reinstate a 20% beneficiary co-payment on Medicare lab tests. It is uncertain whether any or all of the President's proposals regarding laboratory services will be included in the final budget negotiated with Congress. Beginning in 1998, Medicare began covering screening pap smears for certain Medicare beneficiaries, and the Balanced Budget Refinement Act of 1999 ("BBRA") required the Secretary of Health and Human Services ("HHS") to establish a national minimum payment amount equal to $14.60 for diagnostic or screening pap smear laboratory tests furnished on or after January 1, 2000. Previously, the national payment cap for a pap smear was approximately $7.15. The BBRA also encouraged the Health Care Financing Administration ("HCFA") to institute an appropriate increase in the payment rate for new cervical cancer screening technologies that have been approved by the FDA as significantly more effective than a conventional pap smear, such as the technologies used by the Company. The addition of Medicare coverage for these tests and higher reimbursement for certain types of these tests have provided additional revenues for the Company. With respect to the Company's anatomic pathology services, which are not reimbursed under the Medicare laboratory fee schedules, Medicare reimbursement amounts also generally declined with the implementation of the resource-based relative value scale ("RBRVS") system which went into effect in 1992 and was fully phased in by the end of 1996. Beginning with the Medicare physician fee schedule regulation that became effective on January 1, 1999, HCFA recalculated physician practice expenses, a key component of the RBRVS, to reflect resource consumption rather than historical charge data. While the actual impact of this change, when fully implemented, on the pathology revenues of 9 any specific laboratory, including the Company, will depend on the mix of pathology services furnished, HCFA had estimated that the new system would decrease the Medicare revenue for pathologists 13% once it was fully phased in at the end of 2002. However, in the physician fee schedule regulation published on November 2, 1999, and effective January 1, 2000, HCFA increased the conversion factor used to calculate physician payments by approximately 5.5% and made several changes in the payment methodology for physician services, including a modification specific to pathology that had a positive impact. As a result of these changes, HCFA now estimates the impact of the practice expense recalculation will ultimately result in only a 6% decrease for pathology services. In addition, other revisions to payment policies under the physician fee schedule for the year 2000 resulted in increases in the RBRVS fee schedule payment amounts for the pathology codes for some of the most common tests historically performed by the Company. HCFA also has announced that effective January 1, 2001, independent labs may no longer bill Medicare or the patient for the technical component ("TC") of physician pathology services furnished to Medicare beneficiaries who are hospital inpatients. Independent labs would still be able to bill and be paid for the TC of physician pathology services provided to beneficiaries who are in non-hospital settings, but for the TC of services provided to a hospital inpatient, the independent lab will have to make arrangements with the hospital in order to receive payment. Starting July 1, 2000, under new rules for hospital outpatient reimbursement (see following paragraph), independent labs also likely will be limited to billing the hospital for the TC of any pathology services furnished to hospital outpatients. The Balanced Budget Act of 1997 ("BBA") contains measures to establish market-oriented purchasing for Medicare, including prospective payment systems ("PPS") for hospital outpatient services, home health care, and nursing home care. Of these systems, only the skilled nursing facility ("SNF") PPS has been implemented, and since the Company does only minimal clinical laboratory testing for SNF patients, this change is not expected to materially affect the Company's business. On April 7, 2000, HCFA published a final rule to implement the hospital outpatient PPS. This rule, which will be effective July 1, 2000, would segregate clinical laboratory and physician services from the hospital outpatient PPS rates, but would include the technical component of surgical pathology services in the rate. The Company's Form 10-K for the year ended December 31, 1999, previously filed with the Securities and Exchange Commission, contains additional information regarding the complex area of reimbursement. o COST OF SALES Cost of sales, which consists primarily of payroll, laboratory supplies, outside services, logistics and depreciation expense, increased to $12.7 million in the First Quarter 2000 from $9.2 million in the First Quarter 1999. As a percentage of revenues, cost of sales was 58% for both the First Quarter 2000 and the First Quarter 1999. For the First Quarters 2000 and 1999, while percentages were similar, salaries and wages increased to $6.0 million in 2000 from $3.7 million in 1999, primarily reflecting the acquisition of KMD. Overhead expenses (including building rent, utilities, and depreciation) increased to $3.1 million in 2000 from $2.8 million in 1999. Logistics expenses increased to $1.7 million from $1.4 million in 2000 and 1999, respectively and lab supplies increased to $2.0 million from $1.3 million for the corresponding periods. o GROSS PROFIT Gross profit totaled $9.3 million in First Quarter 2000 versus $6.7 million in First Quarter 1999, reflecting a gross profit margin of 42% for both the First Quarter 2000 and the First Quarter 1999. o SELLING, GENERAL AND ADMINISTRATIVE EXPENSES For the First Quarters 2000 and 1999, selling, general and administrative expenses increased to $6.9 million in 2000 from $5.2 million in 1999. While absolute expenses increased, they decreased as a percentage of sales to 31% in the First Quarter 2000 from 33% in the First Quarter 1999. The expense increases were primarily due to higher commissions associated with obtaining new sales; and from increased risk management, medical and other insurance costs due to the acquisition of additional facilities and employees. 10 o AMORTIZATION OF INTANGIBLE ASSETS Amortization of intangible assets increased to $203,000 in the First Quarter 2000 from $48,000 in the First Quarter 1999. This increase was associated with the acquisition of KMD. o RESEARCH AND DEVELOPMENT EXPENSES Research and development expenses increased to $172,000 in the First Quarter 2000 from $119,000 in the First Quarter 1999. This increase is primarily the result of the development of the Carepath program, a disease management information service for patients, physicians and managed care organizations. o INCOME FROM OPERATIONS Income from operations increased to $2.1 million in the First Quarter 2000 from $1.3 million in the First Quarter 1999. The increase in operating income reflects the increase in sales. Earnings before interest, taxes, depreciation and amortization ("EBITDA") for the first quarter 2000 and 1999 are as follows: First Quarter First Quarter 2000 1999 ------------- ------------- EBITDA 3,015,601 2,023,155 EBITDA as a percentage of sales 13.7% 12.8% o NET INTEREST INCOME Net interest income decreased to $44,000 in the First Quarter 2000 from $161,000 in the First Quarter 1999, due to lower income received on less cash invested, and the interest expense related to borrowings drawn from the Company's line of credit which began in April 1999. o PROVISION FOR INCOME TAXES The provision for income taxes reflects a 40.5% and 41.5% effective tax rate in First Quarter 2000 and First Quarter 1999, respectively, totaling $857,000 and $619,000, respectively. The lower effective tax rate is due primarily to state rate changes. o NET INCOME For the first quarters 2000 and 1999, net income increased 44% to $1.3 million in 2000 from $873,000 in 1999. Basic earnings per share increased to $0.18 per share in 2000 from $0.13 per share in 1999, while diluted earnings per share increased to $0.17 per share in 2000 from $0.13 per share in 1999. LIQUIDITY AND CAPITAL RESOURCES - ------------------------------- At March 31, 2000, the Company had total cash and cash equivalents of $10.3 million, substantially all of which was invested in a fund holding U.S. Treasury securities with maturities of less than three months. Working capital was $26.8 million and $25.2 million as of March 31, 2000 and December 31, 1999, respectively, and the current ratios were 4.8:1 and 4.6:1, respectively. Accounts receivable totaled $20.6 million as of March 31, 2000 representing approximately 84 days of sales outstanding, compared to $19.5 million or 86 days as of December 31, 1999. Capital expenditures for the first quarter 2000 and 1999 totaled $440,000 and $398,000, respectively. Effective February 17, 1998, the Company entered into a three-year, $15 million line of credit agreement with a bank. 11 The agreement includes various provisions regarding borrowings under the facility, including those related to financial covenants. As of March 31, 2000, $5.5 million had been drawn down against this line for the acquisition of KMD. The Company's Board of Directors authorized the repurchase of approximately 1.7 million shares of the Company's Common Stock, on the open market or in private transaction. Total expenditures for share repurchases is limited to $12.0 million. The remaining authorized repurchases as of March 31, 2000 is approximately 1.4 million shares and $9.2 million in total expenditures. The Company believes that cash flows from operations and available cash and cash equivalents are adequate to fund the Company's operations for the foreseeable future. RISK FACTORS; FORWARD LOOKING STATEMENTS - ---------------------------------------- The Management's Discussion and Analysis contains forward looking statements regarding the Company's future plans, objectives, and expected performance. These statements are based on assumptions that the Company believes are reasonable, but are subject to a wide range of risks and uncertainties, and a number of factors could cause the Company's actual results to differ materially from those expressed in the forward-looking statements referred to above. These factors include, among others, the uncertainties in reimbursement rates and reimbursement coverage of various tests sold by the Company to beneficiaries of the Medicare program; the possibility of being deemed to be not in compliance with Federal or state regulatory requirements; the uncertainties relating to the ability of the Company to convince physicians and/or managed care organizations to use the Company as a provider of anatomic pathology testing services; the ability of the Company to maintain superior quality relative to its competitors; the ability of the Company to maintain its hospital-based business in light of the competitive pressures and changes occurring in hospital healthcare delivery; the uncertainties relating to states erecting barriers to the performance of national anatomic national laboratories, together with the competitive pressures from small specialized laboratories and well established local pathologists; and the uncertainties which would arise if integrated delivery systems closed to outside providers emerged as the dominant form of health care delivery. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK The Company is not subject to market risk with respect to its cash and cash equivalents since substantially all amounts are invested in a fund holding U.S. Treasury securities with maturities of less than three months. 12 PART II OTHER INFORMATION Item 6 Exhibits and Reports on Form 8-K -------------------------------- (a) Exhibits: (11.1) Statement regarding computation of per share earnings is not required because the relevant computation can be determined from the material contained in the Financial Statements included herein.
