The accompanying notes are an integral part of these unaudited consolidated condensed financial statements. 4 ENZON, INC. AND SUBSIDIARIES Notes To Consolidated Condensed Financial Statements (Unaudited) (1) Organization and Basis of Presentation The unaudited consolidated condensed financial statements have been prepared from the books and records of Enzon, Inc. and subsidiaries in accordance with generally accepted accounting principles for interim financial information. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting only of normal and recurring adjustments) considered necessary for a fair presentation have been included. Interim results are not necessarily indicative of the results that may be expected for the year. Effective July 1, 1998, the Company adopted Statement of Financial Accounting Standards No. 130 ("SFAS 130"), Reporting Comprehensive Income. SFAS 130 establishes new rules for the reporting and display of comprehensive income and its components. The adoption of SFAS 130 had no impact on the Company's results of operations for the three months ended September 30, 1998 and 1997. The net loss of $1,135,000 and the net income of $698,000, recorded for the three months ended September 30, 1998 and 1997, respectively, is equal to the comprehensive income (loss) for those periods. (2) Net Earnings (Loss) Per Common Share Basic and diluted earnings (loss) per common share is based on the net income (loss) for the relevant period, adjusted for cumulative undeclared preferred stock dividends of $54,000 for the three months ended September 30, 1998 and 1997, divided by the weighted average number of shares issued and outstanding during the period. Due to the net loss recorded for the three months ended September 30, 1998, the exercise or conversion of all dilutive potential common shares is not included for purposes of the diluted loss per share calculation. Stock options, warrants and common stock issuable upon conversion of the preferred stock have been included for purposes of the diluted earnings per share computation for the three months ended September 30, 1997. As of September 30, 1998, the Company had 6,750,000 dilutive potential common shares outstanding that could potentially dilute future diluted earnings per share calculations. (3) Inventories The composition of inventories at September 30, 1998 and June 30, 1998 is as follows: September 30, June 30, 1998 1998 ---------- ---------- Raw materials $ 589,000 $ 510,000 Work in process 379,000 398,000 Finished goods 162,000 115,000 ---------- ---------- $1,130,000 $1,023,000 ========== ========== 5 ENZON, INC. AND SUBSIDIARIES Notes To Consolidated Condensed Financial Statements, Continued (Unaudited) (4) Cash Flow Information The Company considers all highly liquid securities with original maturities of three months or less to be cash equivalents. Cash payments for interest were approximately $5,000 and $6,000 for the three months ended September 30, 1998 and 1997, respectively. There were no income tax payments made for the three months ended September 30, 1998 and 1997. There were no conversions of Series A Preferred Stock during the three months ended September 30, 1998. During the three months ended September 30, 1997, 1,000 shares of Series A Cumulative Convertible Preferred Stock ("Series A Preferred Stock") were converted to 2,272 shares of Common Stock. Accrued dividends of $15,000 on the Series A Preferred Stock that was converted during the three months ended September 30, 1997 were settled by issuing 1,358 shares of Common Stock and cash payments totaling $10 for fractional shares. These transactions are non-cash financing activities. (5) Stockholders' Equity In July 1998, the Company sold 3,983,000 shares of Common Stock in a private placement to a small group of investors. The private placement resulted in gross proceeds of approximately $18,919,000 and net proceeds of approximately $17,550,000. During the quarter ended September 30, 1998, 37,500 warrants were exercised to purchase 37,500 shares of the Company's Common Stock at $2.50 per share. These warrants were issued during the year ended June 30, 1996, as part of the commission due to a real estate broker in connection with the termination of the Company's former lease at 40 Kingsbridge Road. (6) Non-Qualified Stock Option Plan During the three months ended September 30, 1998, the Company issued 277,000 stock options at an average exercise price of $6.48 per share under the Company's Non-Qualified Stock Option Plan, as amended, of which 198,000 were granted to executive officers of the Company as part of a bonus plan for the year ended June 30, 1998. None of the options granted during the period are exercisable as of September 30, 1998. All options were granted with exercise prices that equaled or exceeded the fair market value of the underlying stock on the date of grant. (7) Commitments and Contingencies The Company is being sued by a former financial advisor, LBC Capital Resources, Inc. ("LBC"), which is asserting that under a May 2, 1995, letter agreement ("Letter Agreement") between Enzon and LBC Capital Resources, Inc. ("LBC"), LBC was entitled to a commission in connection with the Company's January and March 1996 private placements, comprised of $500,000 and warrants to purchase 1,000,000 shares of Enzon common stock at an exercise price of $2.50 per share. LBC has also asserted that it is entitled to an additional fee of $175,000 and warrants to purchase 250,000 shares of Enzon common stock when and if any of the warrants obtained pursuant to the private placements are exercised. LBC has claimed $3,000,000 in compensatory damages, plus punitive damages, counsel fees and costs for the alleged breach of the Letter Agreement. The Company believes that no such commission was due under the Letter Agreement and denies any liability under the Letter Agreement. The Company intends to defend this lawsuit vigorously. In the course of normal operations, the Company is subject to the marketing and manufacturing regulations as established by the Food and Drug Administration ("FDA"). The Company's quality assurance department has observed increased levels of particulates in certain batches of ONCASPAR, which were manufactured by the Company. These batches were not shipped and the Company's recent rejection rate for the manufacture of this product is significantly higher than it has been historically. Accordingly, such batches were written-off to cost of sales in the period of their occurence. The Company is currently engaged in an extensive review of its manufacturing procedures for this product and believes that the problem may be related to certain materials which are used in the filling process, although this has not yet been determined. The Company has been in discussions with the FDA regarding this problem. The Company and the FDA have agreed to temporary labeling and distribution modifications for ONCASPAR, until the current manufacturing problem is resolved. The Company, rather than Rhone-Poulene Rorer Pharmaceuticals, Inc. ("RPR") will temporarily distribute ONCASPAR directly to patients, on an as needed basis, in order to institute the additional inspection and labeling procedures prior to distribution. Upon resolution of the existing manufacturing problem, it is expected that RPR will resume the normal distribution of ONCASPAR. This manufacturing problem is isolated to ONCASPAR only. 6 Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations Information contained herein contains "forward-looking statements" which can be identified by the use of forward-looking terminology such as "believes," "expects," "may," "will," "should," or "anticipates" or the negative thereof or other variations thereon or comparable terminology, or by discussions of strategy. No assurance can be given that the future results covered by the forward-looking statements will be achieved. The matters set forth in Exhibit 99.0 to the Company's Annual Report on Form 10-K for the fiscal year ended June 30, 1998, which is incorporated herein by reference, constitute cautionary statements identifying important factors with respect to such forward-looking statements, including certain risks and uncertainties, that could cause actual results to vary materially from the future results indicated in such forward-looking statements. Other factors could also cause actual results to vary materially from the future results indicated in such forward-looking statements. Results of Operations Three months ended September 30, 1998 vs. Three months ended September 30, 1997 Revenues. Revenues for the three months ended September 30, 1998 decreased by 36% to $2,988,000 as compared to $4,670,000 for the same period in 1998, due primarily to a decrease in contract revenue. The components of revenues are sales, which consist of sales of the Company's two Food and Drug Administration ("FDA") approved products and royalties on the sales of the Company's products by others, and contract revenues. Sales increased by 19% to $2,936,000 for the three months ended September 30, 1998, as compared to $2,465,000 for the same period in the prior year. The increase was primarily due to an increase in ADAGEN(R) sales of approximately 14%, resulting from an increase in patients receiving ADAGEN treatment from the prior year. Sales of ADAGEN for the three months ended September 30, 1998 and 1997 were $2,493,000 and $2,193,000, respectively. ONCASPAR revenues are comprised of manufacturing revenues, as well as royalties on sales of ONCASPAR by the Company's marketing partner, Rhone-Poulenc Rorer Pharmaceuticals, Inc. ("RPR"). ONCASPAR revenues increased due to an increase in manufacturing revenue resulting from the timing of shipments made to the Company's marketing partner RPR. The increase in manufacturing revenue was partially offset by an increase in the Company's reserve for returns resulting from difficulties encountered in the Company's manufacturing process, described below. The Company's quality assurance department has observed increased levels of particulates in certain batches of ONCASPAR, which were manufactured by the Company. These batches were not shipped and the Company's recent rejection rate for the manufacture of this product is significantly higher than it has been historically. The Company is currently engaged in an extensive review of its manufacturing procedures for this product and believes that the problem may be related to certain materials which are used in the filling process, although this has not yet been determined. The Company has been in discussions with the FDA regarding this problem. The Company and the FDA have agreed to temporary labeling and distribution modifications for ONCASPAR, until the current manufacturing problem is resolved. The Company, rather than RPR, will temporarily distribute ONCASPAR directly to patients, on an as needed basis, in order to institute the additional inspection and labeling procedures prior to distribution. Upon resolution of the existing manufacturing problem, it is expected that RPR will resume the normal distribution of ONCASPAR. This manufacturing problem is isolated to only ONCASPAR. The Company expects sales of ADAGEN to increase at comparable rates to those achieved during the last two years as additional patients are treated. The Company also anticipates that sales of ONCASPAR may decline slightly until the manufacturing issue, discussed in the preceding paragraph, is resolved. There can be no assurance that any particular sales levels of ONCASPAR or ADAGEN will be achieved or maintained. Contract revenue for the three months ended September 30, 1998 decreased by $2,153,000 to $52,000, as compared to $2,205,000 for the same period in 1997. The change was principally due to milestone payments received under the Company's licensing agreement with Schering-Plough Corporation ("Schering-Plough") during 7 the quarter ended September 30, 1997. During the previous year, the Company recognized $2,200,000 in milestone payments received from Schering-Plough related to the advancement of PEG-Intron A into a Phase III clinical trial. During the three months ended September 30, 1998 and 1997, the Company had export sales of $754,000 and $486,000, respectively. Sales in Europe were $600,000 and $359,000 for the quarters ended September 30, 1998 and September 30, 1997, respectively. Cost of Sales. Cost of sales, as a percentage of sales, increased to 45% for the three months ended September 30, 1998 as compared to 25% for the same period in 1997. The increase was primarily due to a charge for ONCASPAR finished goods on hand and in the distribution pipeline, as well as increased ONCASPAR production costs. The increased write-off of ONCASPAR finished goods was attributable to the recently encountered manufacturing problems, as previously discussed. Research and Development. Research and development expenses for the three months ended September 30, 1998 decreased by 27% to $1,575,000 from $2,147,000 for the same period in 1997. The decrease in research and development expenses resulted from (i) the completion of preclinical activities related to PEG-camptothecin and (ii) the reduction in clinical trial costs as a result of the completion of a Phase Ib clinical trial for PEG-hemoglobin. Due to the significant costs associated with the development of this product, the Company is currently looking for a medical institution or commercial partner to bring this product into Phase II clinical trials. Clinical costs are anticipated to increase in future quarters as PEG-camptothecin enters clinical trials. Selling, General and Administrative Expenses. Selling, general and administrative expenses for the three months ended September 30, 1998, increased by 16% to $1,535,000, as compared to $1,328,000 for the same period in 1997. The increase was due to increased investor and public relations activities. Other Income/Expense. Other income/expense increased by $190,000 to $298,000 for the three months ended September 30, 1998, as compared to $108,000 for the same period last year. The increase in other income/expense for the three months ended September 30, 1998 was attributable to an increase in interest income due to an increase in interest bearing investments. Liquidity and Capital Resources Enzon had $23,033,000 in cash and cash equivalents as of September 30, 1998. The Company invests its excess cash in a portfolio of high-grade marketable securities and United States government-backed securities. The Company's cash reserves as of September 30, 1998 increased by $16,554,000 from June 30, 1998. The increase in cash reserves was principally due to net proceeds of approximately $17,550,000 received upon completion of a private placement during July 1998 in which the Company sold 3,983,000 shares of Common Stock to a small group of investors. The Company's exclusive U.S. marketing rights license with RPR for ONCASPAR, as amended, (the "Amended RPR License Agreement") provides for a payment of $3,500,000 in advance royalties, which was received in January 1995. Royalties due under the Amended RPR License Agreement will be offset against an original credit of $5,970,000, which represents the royalty advance plus reimbursement of certain amounts due RPR under the original agreement and interest expense, before cash payments will be made under the agreement. The royalty advance is included in accrued expenses on the consolidated condensed balance sheets and will be reduced as royalties are recognized under the agreement. Through September 30, 1998, an aggregate of $4,690,000 in royalties payable by RPR has been offset against the original credit. As of September 30, 1998, 942,808 shares of Series A Cumulative Convertible Preferred Stock ("Series A Preferred Stock") had been converted into 3,097,955 shares of Common Stock. Accrued dividends on the converted Series A Preferred Stock in the aggregate of $1,824,000 were settled by the issuance of 235,231 shares of Common 8 Stock. The Company does not presently intend to pay cash dividends on the Series A Preferred Stock. As of September 30, 1998, there were $1,824,000 of accrued and unpaid dividends on the Series A Preferred Stock. Dividends accrue on the outstanding Series A Preferred Stock at the rate of $214,000 per year. To date, the Company's sources of cash have been the proceeds from the sale of its stock through public and private placements, sales of ADAGEN, sales of ONCASPAR, sales of its products for research purposes, contract research and development fees, technology transfer and license fees and royalty advances. The Company's current sources of liquidity are its cash, cash equivalents and interest earned on such cash reserves, sales of ADAGEN, sales of ONCASPAR, sales of its products for research purposes and license fees. Based upon its currently planned research and development activities and related costs and its current sources of liquidity, the Company anticipates its current cash reserves will be sufficient to meet its capital and operational requirements for the foreseeable future. Upon exhaustion of the Company's current cash reserves, the Company's continued operations will depend on its ability to realize significant revenues from the commercial sale of its products, raise additional funds through equity or debt financing, or obtain significant licensing, technology transfer or contract research and development fees. There can be no assurance that these sales, financings or revenue generating activities will be successful. Year 2000 The Company has completed a review of its business systems, including its computer systems and manufacturing equipment, and has queried its customers and vendors as to their progress in identifying and addressing problems that their systems may face in correctly interpreting and processing date information as the year 2000 approaches and is reached. Based on this review, the Company has implemented a plan to achieve year 2000 compliance. The Company believes that it will achieve year 2000 compliance no later than September 1999 in a manner which will be non-disruptive to its operations. In addition, the Company has commenced work on various types of contingency planning to address potential problem areas with internal systems and with suppliers and other third parties, although such plans have not yet been determined. Year 2000 compliance should not have a material adverse effect on the Company, including the Company's financial condition, results of operations or cash flow. The Company estimates the cost (including historical costs to date) of its year 2000 efforts to be approximately $400,000. The total cost estimate is based on management's current assessment and is subject to change. However, the Company may encounter problems with suppliers and or revenue sources which could adversely affect the Company's financial condition, results of operations or cash flow. The Company cannot accurately predict the occurence and or outcome of any such problems, nor can the dollar amount of any such problem be estimated. In addition, there can be no assurance that the failure to ensure year 2000 compliance by a third party would not have a material adverse effect on the Company. 9 PART II OTHER INFORMATION Item 2.
