Basis of Presentation The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries after elimination of all significant intercompany accounts and transactions. While the financial information is unaudited, the statements in this report reflect all adjustments, which are normal and recurring, that are necessary for a fair presentation of the results of operations for the interim periods covered and of the financial condition of the Company at the dates of the balance sheets. The operating results for the interim periods presented are not necessarily indicative of performance for the entire year. These financial statements and notes should be read in conjunction with the Company's consolidated financial statements for the fiscal year ended December 31, 1996. 2. Restructuring Charges In the fourth quarter of 1996, senior management reviewed the Company's operational and administrative functions for the purpose of further improving the Company's competitiveness and overall profitability. Based on this review, the Company's Board of Directors approved a strategic restructuring plan to reposition the Company to fully exploit its core strengths in engineering, design, construction, operations and maintenance. The plan included closure or downsizing of underperforming offices, write-offs of employment contracts for former employees no longer participating in the Company's affairs and employee severance. During the six months ended June 30, 1997, $131,000 relating to the restructuring were incurred and charged against the established reserve. At June 30, 1997, $907,000 of accrued restructuring costs, net of a $75,000 reduction due to earlier than anticipated subleasing of abandoned office space, remained and were included in other accrued liabilities. To-date, $250,000 of restructuring costs related to these actions have been incurred. All remaining actions are expected to be substantially completed by the third quarter of 1997. In December 1994, as a result of changes in senior management, the Company's Board of Directors approved a corporate restructuring plan that included the write off of employment contracts with no current or future value, termination of personnel, and the elimination or abandonment of excess and underperforming assets and facilities. During the six months ended June 30, 1997, $27,000 of cash charges related to the restructuring were incurred and charged against the established reserve, bringing the reserve to a zero balance. To date, $1,169,000 of restructuring costs have been incurred with no additional cost anticipated. 6 3. Acquisitions Effective May 1, 1997, Organic Waste Technology, Inc., a wholly owned subsidiary of EMCON, acquired all of the equity interest in National Earth Products, Inc. ("NEP"), a Lancaster, Pennsylvania, based company with significant expertise in civil construction and soils processing around landfills. NEP was acquired for $933,000 in cash and $800,000 in notes payable. The transaction was accounted for as a purchase. Specifically identifiable intangible assets and goodwill of approximately $1,456,000 resulting from this acquisition are included in goodwill and are being amortized over twenty-five years using the straight line method. Accumulated amortization as of June 30, 1997, was approximately $10,000. Additional consideration may be paid for the purchase of NEP subject to the achievement of certain earnout goals over the next three years. This acquisition would not have had a material effect on net revenue, net income, or income per share, had it been effective at January 1, 1997. On February 29, 1996, EMCON acquired all of the outstanding capital stock of Organic Waste Technologies, Inc. ("OWT"), a Cleveland based construction, equipment and operations and maintenance company with significant expertise in solid waste management. The following summarizes the unaudited pro forma net revenue, net income, and income per share for the combined company for the six month period ended June 30, 1997 and 1996 had the acquisition of OWT occurred at the beginning of the period presented. (unaudited) Six months ended June 30, ------------------------------------------ (in thousands) 1997 1996 ------------------------------------------------------------------------- Net revenue $52,048 $58,048 Net income 1,185 83 Income per share $ 0.14 $ 0.02 ------------------------------------------------------------------------- 4. Credit Agreement In conjunction with the acquisition of OWT, the Company entered into a $20,000,000 secured credit agreement with its existing commercial bank, replacing its previous $10,000,000 unsecured line of credit. Under the new agreement, the Company borrowed $10,000,000 on a long term basis with interest at a variable rate, generally not to exceed the prime rate. Principal is to be amortized over seven years, but with any unpaid amount finally due and payable on June 30, 2001. The remaining $10,000,000 under the credit agreement is available on a line of credit basis for working capital purposes (with up to $5,000,000 of this amount available for non-working capital purposes). The line of credit component of the credit agreement expires on May 31, 1998. 7 5. Litigation As a professional services firm engaged in environmental-related matters, the Company encounters potential liability, including claims for significant environmental damage in the normal course of business. The Company is party to lawsuits and is aware of potential exposure related to certain claims, but in the opinion of management the resolution of these matters will not have a material adverse effect on the Company's financial position, results of operations or cash flows. 6. Income Per Share Income per share for the three months and six months ended June 30, 1997 is based on the weighted common and dilutive common equivalent shares outstanding using the treasury stock method. Common equivalent shares include shares issuable under the Company's stock option plans. Primary and fully diluted earnings per share are substantially the same. Income per share for the three months and six months ended June 30, 1996 is based on the weighted average number of common and dilutive common equivalent share outstanding using the modified treasury stock method. In February 1997, the Financial Accounting Standards Board issued Statement No. 128, "Earnings per Share," which is required to be adopted on December 31, 1997. At that time, the Company will be required to change the method currently used to compute earnings per share and to restate all prior periods. Under the new requirements for calculating primary earnings per share, the dilutive effect of stock options will be excluded. The impact is expected to result in no change to the primary earnings per share for the three months and six months ended June 30, 1997 and a $0.01 decrease and a $0.02 decrease to the primary earnings per share for the three month and six months ended June 30, 1996, respectively. The impact of Statement 128 on the calculation of the fully diluted earnings per share for these periods is not expected to be material. 7. Other In 1994, the Company converted to a fifty-two/fifty-three week fiscal year which will result in a fifty-two week year in 1997. The Company's year end falls on the Friday closest to the last day of the calendar year. The Company also follows a five-four-four week quarterly cycle. For convenience, the accompanying financial statements have been shown as ending on the last day of the calendar period. 8 EMCON ITEM 2. Management's Discussion and Analysis of Financial Condition and Results of Operations. RESULTS OF OPERATIONS Current Year-to-Date versus Prior Year-to-Date. Net Revenue: Net revenue for the first six months of 1997 totaled $52,048,000, a 5.6% decrease from $55,149,000 for the first six months of 1996. The decrease was due in part to the divestiture of the Company's laboratory subsidiary, Columbia Analytical Services, Inc. ("CAS"), at the end of the first quarter of 1997 (CAS contributed net revenue of $4,904,000 in the first six months of 1997 and $8,979,000 in the first six months of 1996 ), as well as lower demand for the Company's professional services in the Company's South and Southwest areas. The decrease in net revenue was offset in part by the growth of the Company's Operations and Construction ("EOC") Division from net revenue of $8,174,000 for the first six months of 1996 (following the acquisition of OWT on February 29, 1996) to $15,086,000 for the first six months of 1997. Direct Expenses: Direct expenses include compensation for billable hours for technical and professional staff and other project related expenses. Direct expenses for the first six months of 1997 totaled $24,812,000, a 9.2% increase compared to direct expenses of $22,719,000 for the first six months of 1996. Direct expenses as a percent of net revenue increased to 47.7% in the first six months of 1997 from 41.2% for the comparable period in 1996. The increase was due in large part to the shift in business mix resulting from the divestiture of CAS and the continued expansion of the EOC Division combined with higher utilization of professional staff. Indirect Expenses: Indirect expenses include compensation for nonbillable hours of professional, technical and administrative staff and general administrative expenses such as rent, bonuses, benefits, insurance, legal, depreciation and amortization. Indirect expenses for the first six months of 1997 totaled $25,403,000, a 19.4% decrease compared to indirect expenses of $31,521,000 for the first six months of 1996. Indirect expenses as a percent of net revenue decreased to 48.8% in the first six months of 1997 from 57.2% for the comparable period in 1996. The decrease was due in part to the above-noted shift in business mix following the divestiture of CAS, the expansion of the EOC Division and the planned contraction of the Professional Services Division combined with the positive impact of cost containment and restructuring measures put in place at the end of 1996. Adjustment of Restructuring Accrual: During the first quarter of 1997, the Company reversed an accrual of $75,000 made as part of the restructuring actions taken in the fourth quarter of 1996. The year end accrual was revised to reflect lower than anticipated costs associated with the abandonment and subsequent sublease of certain office space. 9 Loss on Disposition of Laboratory: During the first quarter of 1997, the Company completed the sale of CAS to the employees of CAS for $4,000,000 in cash, CAS' promissory notes for $3,219,000 and a continuing preferred stock interest in CAS valued at $500,000. The Company paid $206,000 in cash to CAS for retired employee contracts and for accelerated vesting of stock options and other non vested stock rights. In anticipation of completing the sale, the Company recognized impairment in the value of its investment in CAS of $3,327,000 at the end of 1996. As a result of several pre closing adjustments, the Company recognized an additional loss on disposition of CAS in the first quarter of 1997 of $333,000. Gain on Sale of Assets: During the quarter ended March 31, 1997, the Company completed the sale of one of its landfill gas-to-energy projects, including the related leasehold production rights and associated machinery and equipment. The Company recognized a gain on disposition of the project of $826,000. Income From Operations: Income from operations for the first six months of 1997 totaled $2,401,000, a 164.1% increase compared to $909,000 for the comparable period in 1996. Income from operations, as a percent of net revenue increased to 4.6% for the first six months of 1997 from 1.6% in the comparable period in 1996. Interest Income (Expense) Net: The Company recorded interest expense, net of interest income of $429,000 and $299,000 for the first six months of 1997 and 1996, respectively. The increase was due primarily to the increase in long-term debt incurred for purposes of financing the acquisition of OWT in February of 1996 and the subsequent expansion of one of OWT's landfill gas-to-energy projects, as well as the acquisition of NEP which was effective on May 1, 1997. Quarters Ended June 30, 1997 and 1996. Net Revenue: For the quarter ended June 30, 1997, net revenue totaled $24,467,000, a 19.9% decrease from net revenue of $30,542,000 in the second quarter of 1996. The decrease in net revenue was attributable to the divestiture of CAS at the end of the first quarter of 1997 (CAS contributed net revenue of $5,269,000 in the second quarter of 1996), as well as lower demand for the Company's professional services in all but the Company's North area. The decrease in net revenue was offset in part by the continued growth of the EOC Division. Direct Expenses: Direct expenses for the quarter ended June 30, 1997 totaled $12,206,000, a 6.3% decrease from direct expenses of $13,030,000 in the comparable period in 1996. Direct expenses as a percent of net revenue increased to 49.9% in the second quarter of 1997 from 42.7% in the comparable period in 1996. The increase was due to the shift in business mix resulting from the divestiture of CAS and the expansion of the EOC Division combined with higher utilization of professional staff. Indirect Expenses: Indirect expenses for the quarter ended June 30, 1997 totaled $11,177,000, a 33.2% decrease from indirect expenses of $16,722,000 in the comparable period in 1996. Indirect expenses as a percent of net revenue decreased to 45.7% in the second quarter of 1997 from 54.8% in the comparable period in 1996. The decrease was largely due to the above-noted change in business mix following the divestiture of CAS, the expansion of the EOC Division and the planned contraction of the Professional Services Division combined with the positive impact of cost containment and restructuring measures put in place at the end of 1996. 10 Income from Operations: Income from operations for the quarter ended June 30, 1997 totaled $1,084,000, a 37.2% increase compared to income from operations of $790,000 in the comparable period in 1996. Income from operations as a percent of net revenue increased to 4.4% in the second quarter of 1997 from 2.6% in the comparable period in 1996. Interest Income (Expense) Net: The Company recorded interest expense net of interest income of $192,000 and $277,000 for the quarters ended June 30, 1997 and 1996, respectively. The net decrease was primarily attributable to a decrease in interest expense associated with a net decrease in the Company's long-term indebtedness and an increase in interest income earned on the note receivable from the CAS divestiture at the end of the first quarter of 1997. LIQUIDITY AND CAPITAL RESOURCES During the first six months of 1997 the Company financed its operations principally from cash on hand, cash generated from the disposition of assets, and from the return on investment of its cash and cash equivalents. Net cash provided by operating activities during the first six months of 1997 was $474,000. In conjunction with the acquisition of OWT, the Company entered into a $20,000,000 secured credit agreement with its existing commercial bank, replacing its previous $10,000,000 unsecured line of credit. Under the new agreement, the Company borrowed $10,000,000 on a term loan basis with interest at a variable rate, generally not to exceed the prime rate. Principal is to be amortized over seven years, but with any unpaid amount finally due and payable on June 30, 2001. In April 1997, following the infusion of cash upon the sale of CAS, the Company prepaid, on an accelerated basis, $3,000,000 of the then outstanding principal balance of the term loan. The remaining $10,000,000 under the credit agreement is available on a line of credit basis for working capital purposes (with up to $5,000,000 of this amount also being available for non-working capital purposes). The line of credit component of the credit agreement expires on May 31, 1998. The credit agreement contains provisions with respect to the payment of dividends and the level of capital expenditures and requires the maintenance of specific levels of working capital, tangible net worth and continued quarterly profitability. The Company invested $2,341,000 in the first six months of 1997 in additions to property and equipment; mainly computers, field equipment and the expansion of its equipment fabrication facilities. The Company believes that its cash on hand and cash generated from operations, together with its available bank financing will be sufficient to meet the Company's capital needs for at least the next twelve months. 11 EMCON PART II OTHER INFORMATION Items 1. - 3.
