MANAGEMENT REPRESENTATION The consolidated financial statements at March 31, 2000 and 1999 and for the three month periods then ended have not been examined by independent accountants, but in the opinion of the management of Keithley Instruments, Inc., all adjustments necessary to a fair statement of the consolidated balance sheet, consolidated statement of income and consolidated statement of cash flows for those periods have been included. All adjustments included are of a normal, recurring nature. B. EARNINGS PER SHARE DENOMINATOR The weighted average number of shares and share equivalents used in determining basic earnings per share and diluted earnings per share was 7,172,929 and 7,915,608 for the quarter ended March 31, 2000, respectively, and 7,504,111 and 7,695,322 for the quarter ended March 31, 1999, respectively. The weighted average number of shares and share equivalents used to determine basic earnings per share and diluted earnings per share was 7,146,043 and 7,838,725, for the six months ended March 31, 2000, respectively, and 7,664,545 and 7,819,524 for the six months ended March 31, 1999, respectively. Both Common Shares and Class B Common Shares are included in calculating the weighted average number of shares outstanding. C. SALE OF ASSETS On November 9, 1998, the company sold certain assets used in the operation of its Quantox product line to KLA-Tencor Corporation for $9,147 in cash. The agreement, which was effective October 31, 1998, included the sale of the Quantox inventory, certain machinery, equipment and other tangible personal property. The company retained the accounts receivable. The sale resulted in a pretax gain of $4,808, or $0.39 per share after taxes, recorded in the first quarter of fiscal 1999. Additional pretax gains of $345, or $0.03 per share after taxes, and of $477 pretax, or $0.04 per share after taxes, were recorded in the fourth quarter of fiscal 1999 and the first quarter of fiscal 2000, respectively, for businesses previously sold. At the time of the sales of these businesses, the company established liabilities for certain items that were to be settled at future dates. The additional adjustments represent the settlement of certain of these issues. D. DUTCH AUCTION AND STOCK REPURCHASE PROGRAM On November 11, 1998, the company commenced a tender offer to repurchase up to 2,000,000 of its Common Shares, or approximately 25 percent of the outstanding Common Shares and Class B Common Shares combined. The offer was conducted through a procedure commonly known as a "Dutch Auction" in which shareholders could tender their shares at prices not in excess of $7.00 nor less than $5.75 per share. The offer expired on December 10, 1998, and resulted in the purchase of 405,733 Common Shares at $7.00 per share plus expenses of approximately $1.00 per share. 5 6 At the conclusion of the Dutch Auction, the company's Board of Directors approved a program to repurchase up to 1,000,000 Common Shares on the open market over a two-year period. The shares repurchased under both the Dutch Auction and the stock repurchase program will be held as treasury stock, and from time to time, may be reissued in settlement of stock options and the company's employee stock purchase plan. The company did not repurchase any Common Shares during the second quarter of fiscal 2000. Since the start of the repurchase programs, the company has repurchased a total of 1,095,203 Common Shares, or approximately 14 percent of the combined Common and Class B Common Shares, at an average cost of $10.39 per share including commissions. The program, as authorized by the company's Board of Directors, allows for the repurchase of an additional 310,530 shares through December 2000. During the second quarter of fiscal 2000, the company reissued 207,496 shares (399,019 total since the start of the repurchase program) in settlement of shares purchased through the company's employee stock option and employee stock purchase plans. E. COMPREHENSIVE INCOME On October 1, 1998, the company adopted Financial Accounting Standards Board (FASB) Statement of Financial Accounting Standards No. 130, "Reporting Comprehensive Income" (SFAS 130), which establishes rules for reporting comprehensive income and its components. The adoption of SFAS 130 did not impact the company's net income or total shareholders' equity. Comprehensive income for the three and six months ended March 31, 2000 and 1999 is as follows: FOR THE THREE MONTHS FOR THE SIX MONTHS ENDED MARCH 31, ENDED MARCH 31, 2000 1999 2000 1999 ---- ---- ---- ---- Net income $4,826 $1,984 $8,336 $5,767 Foreign currency translation adjustments (250) (263) (537) (317) ------ ------ ------ ------ Comprehensive income $4,576 $1,721 $7,799 $5,450 ===== ===== ===== ===== F. SEGMENT AND GEOGRAPHIC INFORMATION The company adopted FASB Statement of Financial Accounting Standards No. 131, "Disclosures about Segments of an Enterprise and Related Information," for the fiscal year ended September 30, 1999. This statement designated the internal organization, that is used by management, for making operating decisions and assessing performance as the source of the Company's reportable segments. It also required disclosures about products and service, geographic areas and major customers. The Company's business is to develop measurement-based solutions to verify customers' product performance. All the Company's products are computer based (multi-point) systems operating under software control. The Company's customers are engineers, technicians and scientists in manufacturing, product development and research functions within a range of industries. Keithley's advanced hardware and software is used for 6 7 process monitoring, production test and basic research. Although the Company's products vary in capability, sophistication, use, size and price, they basically test, measure and analyze electrical and physical properties. As such, the Company's management determined the Company operates in a single industry segment. The operations by geographic area are presented below. The basis for attributing revenues from external customers to a geographic area is the location of the customer.

RECENT ACCOUNTING STANDARDS CHANGES In December 1999, the Securities and Exchange Commission ("SEC") issued Staff Accounting Bulletin ("SAB") 101, Revenue Recognition in Financial Statements which provides guidance related to revenue recognition based on interpretations and practices followed by the SEC. SAB 101 is effective the first quarter of the company's fiscal year 2001, and requires the reporting of any changes in revenue recognition as a cumulative change in accounting principle at the time of implementation in accordance with Accounting Principles Board Opinion 20, Accounting Changes. The Company will adopt SAB 101 and is currently in the process of evaluating what impact, if any, SAB 101 will have on the financial position or results of operations of the Company. H. SUBSEQUENT EVENT On May 8, 2000, the company announced its Board of Directors had approved a two-for-one stock split of the company's Common Shares and Class B Common Shares. New shares will be issued on June 1 to shareholders of record on May 18. Following the stock split, the company will have approximately 14.7 million Common Shares and Class B Common Shares outstanding. 7 8 ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS. (In Thousands of Dollars) RESULTS OF OPERATIONS SECOND QUARTER 2000 COMPARED WITH SECOND QUARTER 1999 Net income was a record high for the second quarter of fiscal 2000 at $4,826, or $0.61 per share, compared to $1,984, or $0.26 per share, in fiscal 1999's second quarter, a 143 percent increase. The 2000 quarter's results represent the fifth consecutive quarter of record earnings before gains on sales of businesses and a one-time favorable income tax adjustment. Net sales of $37,271 increased 53 percent from $24,387 in the prior year's second quarter. This was principally due to strong sales for the company's products serving the telecommunications, semiconductor and optoelectronic industries. Sales were up significantly in all major geographies. Sequentially, sales grew 25 percent from the first quarter record sales. Orders for the second quarter of fiscal 2000 of $41,743 were a record high and up 52 percent from the prior year's quarter. Orders for the company's products serving the telecommunications and optoelectronics industries were record highs, and orders for the semiconductor industry remained strong. Compared to the prior year, orders were up substantially in all major geographies with the Pacific Basin and Europe particularly strong; up 93 percent and 79 percent, respectively. Additionally, new products introduced during the first half of fiscal 2000 have been well received. The Model 2510 TEC Source Meter designed for the optoelectronics industry was introduced in February and orders during the quarter exceeded the company's expectations. Orders for the Model 2700 Multimeter/Data Acquisition System introduced during the first quarter for broader test and measurement use have also been strong. Order backlog increased $5,659 for the quarter to a record $30,318 at March 31, 2000. Cost of goods sold as a percentage of net sales decreased 1.2 percentage points to 38.8 percent from 40.0 percent. Improved manufacturing efficiencies as a result of higher sales, and favorable product and geographic mix offset the unfavorable impact of a 9 percent stronger dollar resulting in improved gross margins. The effect of foreign exchange hedging on cost of goods sold was immaterial in both periods. Selling, general and administrative expenses of $12,411 increased 36 percent from $9,118 in last year's second quarter, but decreased as a percentage of net sales to 33.3 percent versus 37.4 percent, a 4.1 point improvement. The increase in dollars was due to higher expenses related to increased sales, increased promotion and E-business initiatives, and marketing expenses related to the company's target industry focus. Product development expenses of $2,923 increased $127, or 5 percent, from $2,796 in the prior year's quarter. As a percentage of net sales, product development for the second quarter of fiscal 2000 was 7.8 compared to 11.4 percent in last year's quarter. 8 9 SIX MONTHS ENDED MARCH 31, 2000 COMPARED WITH SIX MONTHS ENDED MARCH 31, 1999 Net income excluding gains on the sale of a previously disposed business was $8,033, or $1.02 per share, for the six months ending March 31, 2000, compared with $2,677, or $0.35 per share, last year on a comparable basis. Net income as reported including the gains was $8,336, or $1.06 per share, in the 2000 first half, compared with $5,767, or $0.74 per share, last year. Net sales of $67,031 increased 48 percent from $45,268 reported for the six month period last year. Excluding sales from Quantox in last year's period, net sales increased 50 percent. The sales increase was principally due to strong sales for the company's products serving the semiconductor, telecommunications and optoelectronics industries. Sales were up significantly in all major geographies. Orders for the six month period, excluding Quantox in the prior year, were up 56 percent versus last year. Strong orders for the company's products serving the semiconductor, telecommunications and optoelectronics industries accounted for the increase. Orders were up significantly in all major geographies. Cost of goods sold as a percentage of net sales decreased to 39.1 percent from 41.0 percent for the six month period last year. Improved manufacturing efficiencies as a result of higher sales, and favorable product and geographic mix offset the unfavorable impact of a 9 percent stronger dollar. The effect of foreign exchange hedging on cost of goods sold was immaterial in both periods. Selling, general and administrative expenses of $22,750 increased 26 percent from $17,986 in the same period last year, but decreased as a percentage of net sales to 33.9 from 39.7. The majority of the increase in dollars was due to higher expenses related to increased sales, increased promotion and E-business initiatives, and marketing expenses related to the company's target industry focus. Product development expenses of $5,751, or 8.6 percent of sales, increased 13 percent from $5,078, or 11.2 percent of sales, in the prior year. The increase is primarily due to development costs for new products introduced during the first and second quarters including the Model 2700 Multimeter/Data Acquisition System, PCI Data Acquisition boards and the Model 2510 TEC Source Meter, as well as products that will be introduced during the remainder of fiscal 2000. On November 9, 1998, the company sold certain assets used in the operation of its Quantox product line to KLA-Tencor Corporation. The sale was effective October 31, 1998, and resulted in a gain of $4,808 pretax, or $0.39 per share after taxes, recorded in the first quarter of fiscal 1999. During the first quarter of fiscal 2000, an additional pretax gain of $477, or $0.04 per share after taxes, was recorded for the sale. At the time of the sale of this business, the company established liabilities for certain items that were to be settled at future dates. The additional adjustment recorded in the first quarter of fiscal 2000 represents the settlement of certain of these issues. (See Note C.) The company generated net financing income during the first half of fiscal 2000 of $137 versus $74 in the prior year. Lower average debt levels resulting in lower interest expense combined with increased interest income earned on cash and cash equivalents accounted for the improvement. 9 10 The effective tax rate was 35.5 percent for the current six month period compared to 32.4 percent last year. The tax rate for the prior year period on earnings excluding the gain on the sale of Quantox was 28.0 percent. The increase in the rate was due to higher earnings and the utilization of tax credits in the prior year, which are not available in the current year. LIQUIDITY AND CAPITAL RESOURCES Cash generated from operations was $1,978 for the second quarter and $4,444 for the six months ended March 31, 2000. Cash used to fund working capital needs totaled $4,852 and $6,431, and capital expenditures totaled $1,505 and $2,051 for the second quarter and first half of fiscal 2000, respectively. At March 31, 2000, cash and cash equivalents totaled $14,246, total debt was $3,147, and the debt-to-capital ratio was 5.9 percent. The company expects to finance debt service, capital spending, the stock repurchase program and working capital requirements with cash on hand and cash provided by operations. At March 31, 2000, the Company had available unused lines of credit with domestic and foreign banks aggregating $26,852, of which $4,852 were short term and $22,000 were long term. OUTLOOK The company plans to add development and applications engineering resources over the next several quarters to take advantage of the growth opportunities that exist in its targeted industries, including the telecommunications, optoelectronics and semiconductor industries. The company's goal is for product development efforts to total 10 to 11 percent of net sales. The company was below that goal due to the rapid increase in sales during the second quarter. Due to the record backlog level along with current business activity in the telecommunications, optoelectronics and semiconductor industries, management believes that the third quarter's sales and earnings should be better than those of the second quarter, however, continued success will depend on further investment by customers in these key electronic industries. FACTORS THAT MAY AFFECT FUTURE RESULTS Information included above in the Outlook section of Management's Discussion and Analysis of Financial Condition and Results of Operations relating to expectations as to the company's cost structure, sales and earnings growth for the third quarter and future financial results, constitute "forward-looking" statements, as that term is defined in the Private Securities Litigation Reform Act of 1995. Such statements are subject to certain risks and uncertainties that could cause actual results to differ materially from those projected. Some of the factors that may affect future results are discussed below. Although the company operates in a single industry segment, certain of its products and product lines are targeted for specific industries including the semiconductor, telecommunications, 10 11 optoelectronics, and other electronic industries. Industry forecasts over the next few years look strong; however, these industries, particularly the semiconductor industry, can be cyclical in nature. Growth in demand for semiconductors, new technology and pricing drive the demand for new semiconductor capital equipment. Historically, sales and order levels for this business have been volatile which can affect revenue and earnings for the company. The company's business relies on the development of new high technology products and services to provide solutions to customers' complex measurement needs. This requires anticipation of customers' changing needs and emerging technology trends. The company must make long-term investments and commit significant resources before knowing whether its expectations will eventually result in products that achieve market acceptance. The company incurs significant expenses developing new products that may or may not result in significant sources of revenue and earnings in the future. In many cases the company's products compete directly with those offered by other manufacturers. If any of the company's competitors were to develop products or services that are more cost-effective or technically superior, demand for the company's product offerings could slow. The company's cost structure is comprised of costs that are directly related to the level of sales, as well as costs that are fixed and do not fluctuate based on quarterly sales levels. The company's quality of earnings depends on its ability to control those costs that are fixed or semi-variable. The company currently has ten subsidiaries or sales offices located outside the United States, and non-U.S. sales made up half of the company's revenue in the first half of fiscal 2000. The company's future results could be adversely affected by several factors, including changes in foreign currency exchange rates, changes in a country's or region's political or economic conditions, trade protection measures, import or export licensing requirements, unexpected changes in regulatory requirements and natural disasters. The company has modified its systems to accommodate the Euro. The cost of these modifications was immaterial to the company's results of operations. Although difficult to predict, any competitive implications and any impact on existing financial instruments are expected to be immaterial to the company's results of operations, financial condition or cash flows of future periods. 11 12 PART II.
