IBIS TECHNOLOGY CORPORATION
NOTES TO UNAUDITED INTERIM FINANCIAL STATEMENTS
(1) Interim Financial Statements
The accompanying financial statements are unaudited, except for the Balance Sheet as of December 31, 2002, and have been prepared by the Company in accordance with accounting principles generally accepted in the United States of America.
In the opinion of management, the interim financial statements include all adjustments which consist only of normal and recurring adjustments necessary for a fair presentation of the Company's financial position and results of operations. Results of operations for the interim periods are not necessarily indicative of the results to be expected for the full year. These financial statements should be read in conjunction with the financial statements of the Company as of and for the year ended December 31, 2002 which are included in the Company's Annual Report on Form 10-K.
(2) Summary of Significant Accounting Policies
(a) Revenue Recognition
The Company recognizes revenue from product sales, equipment sales and the sales of spare parts when all of the following criteria have been met: (1) evidence exists that the customer is bound to the transaction; (2) the product has been delivered to the customer; (3) the sales price to the customer has been fixed or is determinable; and (4) collectibility of the sales price is reasonably assured. Provisions for estimated sales returns and allowances are made at the time the products are sold. Revenue derived from services is recognized upon performance. Contract revenue is recognized on the percentage-of-completion method. Provisions for anticipated losses are made in the period in which such losses become determinable. Unbilled revenue under customer contracts represents revenue earned under the percentage-of-completion method but not yet billable under the terms of the contract. These amounts are billable based on the terms of the contract, which can include shipment of the product, achievement of milestones or completion of the contract.
(b) Stock-Based Compensation
The Company accounts for its stock option plans under the recognition and measurement principles of APB Opinion No. 25, "Accounting for Stock Issued to Employees, and Related Interpretations." No stock-based compensation cost is reflected in net income (loss) for these plans, as all options granted under these plans had an exercise price equal to the market value of the underlying common stock on the date of grant. The following table illustrates the effect on net loss and loss per share if we had applied the fair value recognition provisions of FASB Statement No. 123, "Accounting for Stock Based Compensation", to stock based compensation:

| Basic and dilutedas reported | $ | (0.44 | ) | $ | (0.45 | ) | ||
| Basic and dilutedpro-forma | $ | (0.73 | ) | $ | (0.61 | ) | ||
The fair value of each stock option is estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions:

||||||
|---|---|---|---|---|---|---|---|
| |
200 |

| Expected life (years) | 3 | 3 | |||||
| Weighted average fair value of options granted during the quarter | $ | 16.36 | $ | 7.62 | |||
Pro-forma net loss reflects only options granted in 1995 through 2002. Therefore, the full impact of calculating compensation costs for stock options under SFAS No. 123 is not reflected because compensation costs for options granted prior to January 1, 1995, are not considered.
(3) Inventories
Inventories consist of the following:

|---|---|---|---|---|---|---|
| Raw materials | $ | 810,740 | $ | 1,031,204 | ||

| Finished goods | 326,729 | 295,784 | ||||
| Total inventory | $ | 1,231,559 | $ | 1,633,641 | ||
(4) Capitalization
In March 2002, Ibis completed a public offering of 900,000 shares of common stock at $13 per share, and on April 1, 2002, 100,000 shares were exercised as an over allotment option by the underwriter. Net proceeds to the Company were approximately $12,100,000, of which approximately $10,900,000 was received as of March 31, 2002.
(5) Net Loss Per Share
Net loss per share of common stock is computed based upon the weighted average number of shares outstanding during each period and including the dilutive effect, if any, of stock options and warrants. SFAS 128 requires the presentation of basic and diluted earnings (loss) per share for all periods presented. As the Company was in a net loss position for the three months ended March 31,
7
2002 and March 31, 2003, common stock equivalents of 122,935, and 1,449, respectively, were excluded from the diluted loss per share calculation, as they would be antidilutive. As a result, diluted loss per share is the same as basic loss per share for all periods presented.
(6) Industry Segments
The Company's reportable segments are SIMOX Wafer Products, SIMOX Equipment and Other Products or Services. For purposes of segment reporting, equipment, equipment spares and field service revenue are combined and reported as SIMOX Equipment. Government contracts, other services and license revenue are combined and reported as Other Products or Services.
The table below provides unaudited information for the three months ended March 31, 2002 and 2003 pertaining to the Company's three industry segments.

IBIS TECHNOLOGY CORPORATION
MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS
OVERVIEW
Ibis Technology Corporation ("Ibis") was formed in October 1987 and commenced operations in January 1988. Ibis' initial activities consisted of producing and selling SIMOX-SOI wafers and conducting research and development activities. This research led to the development of proprietary next generation oxygen implanters, the Ibis 1000, which we began selling in 1996, and the i2000, and also to other proprietary process technology.
Initially, much of our revenue was derived from research and development contracts and sales of wafers for military applications. Over the years, there was a shift in revenue to sales of SIMOX-SOI wafers for commercial applications and the nature of our business has evolved through stages where sometimes our revenues primarily resulted from selling wafers for evaluation purposes, and sometimes our revenue was generated primarily from equipment sales. This is a normal path to follow while developing and promoting a fundamental new technology, especially when it relates to the semiconductor industry embracing any change that affects fabrication operations. This trend is expected to continue in the near-term as our customers continue to sample SOI and the early adopters work to achieve stable production processes and enter pilot production. We believe that we are in the technology rollout stage of our corporate life cycle. Our fundamental SIMOX-SOI technology has been developed, refined, and proven over the last dozen years. In 2002, Ibis introduced the next generation production-worthy SIMOX-SOI, which includes both the modified low dose ("MLD") wafer process licensed to Ibis by IBM and the i2000, our next-generation oxygen implanter, which is capable of producing eight and twelve inch (or 200 and 300 mm) SIMOX-SOI wafers. In 1999, we commenced a program to design and develop the i2000, introduced it in March 2002 and began shipping 300 mm wafers implanted from this machine shortly thereafter. In September 2002, we received an order valued at approximately $8 million for an i2000 oxygen implanter from a major semiconductor manufacturer. The implanter was shipped to this customer in the last quarter of 2002 and is undergoing factory acceptance.
Wafer product sales this quarter were down, as expected, mainly because wafer production was delayed while our largest wafer customer was evaluating multiple types of MLD wafers for 300 mm production. During the quarter, we also applied several reliability upgrades to our internal i2000 implanter. Although these events took somewhat longer than anticipated and limited our ability to ship 300 mm wafers, we achieved a significant number of goals that position us for near-term growth:
11
Commercial shipments of our wafers have been used principally for evaluation purposes or pilot production in products, including microprocessors, gate arrays, ASICs (application specific integrated circuits), memories (DRAMs, SRAMs, etc.), and cellular and mobile radio components. From our customers' perspective, the pathway to SOI adoption is complex and time consuming. Typically, a customer will go through three major stages:
Each of these stages has many steps, and customers must evaluate each new wafer technology that essentially lays a new foundation for substantially all other processes they have spent billions of dollars and decades of time developing. Accordingly, it takes anywhere from 12 to 36 months for a customer to proceed from initial sampling through R&D to initial production, which is not unlike the standard process for qualifying any new wafer material. These steps apply each time there is a change in the customer's fabrication process, such as a feature-size change or new material. To date, most of our customers have purchased wafers for the purpose of characterizing and evaluating the wafers, developing prototype products or for pilot production, consequently historical sales are not necessarily an indication of future operations.
At March 31, 2003, Ibis had eight Ibis 1000 implanters, two of which are owned by a customer, available to produce up to 200 mm SIMOX wafers and two i2000's available to produce 300 mm SIMOX wafers. One more Ibis 1000 implanter is available for sale and an additional one is dedicated as a research and development tool. We also have one additional i2000 implanter under construction that will be available for sale or utilized internally for wafer production. Although our 200 mm and smaller wafer size production line is currently underutilized, considering our future plans, current potential business prospects and alternatives, Management believes that we do not have an impairment issue at this time. However, if our future plans and potential business prospects do not materialize, if semiconductor manufacturers fail to adopt SIMOX technology during the current process cycle (which typically last two to three years) or our customers transition to the 300 mm wafer size sooner than we anticipate, our 200 mm and smaller wafer size production line may become obsolete and we would be required to reduce our income by an impairment loss which could be material.
We will continue to review our assumptions about our long-lived assets on a periodic basis for potential impairment in future quarters. We cannot be sure that our implanters or other long-lived assets will not become impaired in the future. In addition, the impairment factors evaluated by Management may change in subsequent periods, given the current trends of the business environment.
Ibis has experienced quarterly and annual fluctuations in revenue and results of operations due to the timing of receipt of equipment orders and dependence on a limited number of customers. We expect to continue to experience fluctuations in revenue due to equipment sales and shifts in customer demands during various stages of the SIMOX-SOI sales cycle. We recognize implanter revenue in accordance with SAB 101, which includes among other criteria, the shipment and factory installation of the implanter at the customer's location. As a result, deferral of revenue may extend longer due to meeting these criteria.
Critical Accounting Policies
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that have a
12
significant impact on the results we report in our financial statements. Some of our accounting policies require us to make difficult and subjective judgments, often as a result of the need to make estimates of matters that are inherently uncertain. Our most critical accounting policies include: revenue recognition, inventory valuation and reserves, accounts receivable reserves and the assessment of long-lived asset impairment. Actual results may differ from these estimates under different assumptions or conditions. Below, we discuss these policies further, as well as the estimates and judgments involved.
Revenue Recognition. We recognize revenue from product sales, equipment sales and the sales of spare parts when all of the following criteria have been met: (1) evidence exists that the customer is bound to the transaction; (2) the product has been delivered to the customer and, when applicable, the product has been installed and accepted by the customer; (3) the sales price to the customer has been fixed or is determinable; and (4) collectibility of the sale price is reasonably assured. Provisions for estimated sales returns and allowances are made at the time the products are sold. Revenue derived from contracts and services is recognized upon performance. Significant management judgments and estimates must be made and used in connection with revenue recognized in any period. Management analyzes various factors, including a review of specific transactions, historical experience, credit worthiness of customers and current market and economic conditions. Changes in judgments based upon these factors could impact the timing and amount of revenue and cost recognized.
Inventory Valuation and Reserves. Our policy for the valuation of inventory, including the determination of obsolete or excess inventory, requires us to estimate the future demand for our products within specific time horizons, generally twelve months or less. If our estimated demand for specific products is greater than actual demand and we fail to reduce manufacturing output accordingly, we could be required to record additional inventory reserves, which would have a negative impact on our gross margin. We reserve for a possible over supply of wafers utilizing inventory aging records and for obsolescence when engineering changes or other technological advances indicate that obsolescence has occurred. We also adjust the valuation of inventory when estimated actual cost is significantly different than standard cost and value inventory at the lower of cost or market. Once established, any write-downs of inventory are considered permanent adjustments to the cost basis of the inventory.
Accounts Receivable Reserves. Accounts receivable are reduced by an allowance for amounts that may become uncollectible in the future. The estimated allowance for uncollectible amounts is based primarily on a specific analysis of accounts in the receivable portfolio and a general reserve based on the aging of receivables and historical write-off experience. While management believes the allowance to be adequate, if the financial condition of our customers were to deteriorate, resulting in impairment of their ability to make payments, additional allowances may be required and could materially impact our financial position and results of operations.
