NOTES TO THE UNAUDITED INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

CYBEROPTICS CORPORATION

1. INTERIM REPORTING:

The interim condensed consolidated financial statements of CyberOptics Corporation and its wholly-owned subsidiaries ("we", "us" or "our") presented herein as of June 30, 2022, and for the three and six month periods ended June 30, 2022 and 2021, are unaudited but, in the opinion of management, include all adjustments, consisting of normal recurring adjustments necessary, for a fair presentation of financial position, results of operations and cash flows for the periods presented.

The results of operations for the three and six month periods ended June 30, 2022 do not necessarily indicate the results to be expected for the full year. The December 31, 2021 consolidated balance sheet data was derived from audited consolidated financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America ("U.S. GAAP"). The unaudited interim condensed consolidated financial statements should be read in conjunction with our consolidated financial statements and notes thereto contained in our Annual Report on Form 10-K for the year ended December 31, 2021.

2. COVID-19 PANDEMIC:

Effect of Covid-19 Outbreak on Business Operations

The Covid-19 outbreak has not had a significant impact on our business to date. The potential impact of Covid-19 on our business, results of operations, liquidity and prospects in the future is not fully known at this time.  The following factors related to the Covid-19 outbreak may affect our business in the future:

· Sales of some products, mainly our SQ3000 Multi-Function systems and MX memory module inspection products, require customer acceptance due to performance or other criteria that is considered more than a formality. Global travel restrictions and quarantine measures could hinder our ability to obtain customer acceptances in a timely manner in the future, and therefore impact the timing of revenue recognition. In addition, government mandated shelter-in-place orders or quarantine measures could cause delays in our ability to deliver our products to customers, or cause customers to delay purchases of our products, negatively impacting our revenue and profitability.

·
The Covid-19 pandemic has caused disruptions in the global supply chain, including shortages of raw materials, parts and labor, and shipping and logistics issues, including delays in ocean freight and port congestion. The inability to obtain adequate supply of components or labor could result in the inability to meet customer demands and delivery of one or more of our products for a period of several months or longer, negatively impacting our revenue and profitability. Supply chain disruptions are expected to continue for the foreseeable future and may increase if the pandemic worsens or continues for an extended period of time. 

Although we cannot estimate the continuing impact of the Covid-19 outbreak at this time, it may have an adverse effect on our results of future operations, financial position and liquidity. 

3. RECENT ACCOUNTING DEVELOPMENTS: 

In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments, which revises guidance for the accounting for credit losses on financial instruments within its scope, and in November 2018, issued ASU No. 2018-19, which amended the standard. The new standard introduces an approach to estimating credit losses that is based on expected losses (referred to as the current expected credit losses model), and applies to most financial assets measured at amortized cost and certain other instruments, including available-for-sale marketable debt securities, trade and other receivables. The new standard is effective for us on January 1, 2023, with early adoption permitted. We are required to apply the standard's provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. We presently do not believe the new standard will have a material impact on our consolidated financial statements. 

No other new accounting pronouncements are expected to have a significant impact on our consolidated financial statements.

4. REVENUE RECOGNITION:

Our revenue performance obligations are primarily satisfied at a point in time and limited revenue streams are satisfied over time as work progresses.

The following is a summary of our revenue performance obligations:

	Three Months Ended June 30, 2022				Three Months Ended June 30, 2021
(In thousands except percentages)	Revenues		Percent of Revenues		Revenues		Percent of Revenues
Revenue recognized over time	$	748	2.7	%	$	695	2.8	%
Revenue recognized at a point in time		26,821	97.3	%		24,509	97.2	%
	$	27,569	100.0	%	$	25,204	100.0	%

	Six Months Ended June 30, 2022				Six Months Ended June 30, 2021
(In thousands except percentages)	Revenues		Percent of Revenues		Revenues		Percent of Revenues
Revenue recognized over time	$	1,590	3.1	%	$	1,098	2.6	%
Revenue recognized at a point in time		50,225	96.9	%		41,838	97.4	%
	$	51,815	100.0	%	$	42,936	100.0	%

See Note 11 for additional information regarding disaggregation of revenue. 

Contract Balances

Contract assets consist of unbilled amounts from sales where we recognize the revenue over time and the revenue recognized exceeds the amount billed to the customer at a point in time. Accounts and trade notes receivable are recorded when the right to payment becomes unconditional. Contract liabilities consist of payments received in advance of performance under the contract. Contract liabilities are recognized as revenue when we perform under the contract.   

The following summarizes our contract assets and contract liabilities:     

(In thousands)	June 30, 2022		December 31, 2021
Contract assets, included in other current assets	$	171	$	7
Contract liabilities - advance customer payments	$	359	$	289
Contract liabilities - deferred warranty revenue	$	454	$	445

Changes in contract assets in the six months ended June 30, 2022 and the six months ended June 30, 2021 resulted from unbilled amounts under sensor product arrangements and longer duration 3D scanning service projects in which revenue is recognized over time. Changes in contract liabilities primarily resulted from reclassification of beginning contract liabilities to revenue as performance obligations were satisfied or from cash received in advance and not recognized as revenue. See Note 9 for changes in contractual obligations related to deferred warranty revenue. Unsatisfied performance obligations for deferred warranty revenue are generally expected to be recognized as revenue over the next one to three years. There were no impairment losses for contract assets in the six months ended June 30, 2022 or the six months ended June 30, 2021.  

The following summarizes the amounts reclassified from beginning contract liabilities to revenue:  

	Three Months Ended June 30,					Six Months Ended June 30,
(In thousands)	2022		2021			2022		2021
Amounts reclassified from beginning contract liabilities to revenue	$	624	$	120	$	182	$	345
Amounts reclassified from deferred warranty revenue		102		98		198		161
Total	$	726	$	218	$	380	$	506

At June 30, 2022 and December 31, 2021, investments in marketable debt securities in an unrealized loss position were as follows:  

	In Unrealized Loss Position For Less Than 12 Months					In Unrealized Loss Position For Greater Than 12 Months
(In thousands)	Fair Value		Gross Unrealized Losses			Fair Value		Gross Unrealized Losses

Asset backed securities	1,278		(11		)	—		—
Marketable securities	$	15,716	$	(86	)	$	355	$	(2	)

Our long-term investments in marketable debt securities all have maturities of less than five years. Net pre-tax unrealized losses for marketable debt securities of $662,000 at June 30, 2022 and $43,000 at December 31, 2021 have been recorded as a component of accumulated other comprehensive loss in stockholders’ equity. We only invest in highly rated investment grade debt securities. We have determined that the net pre-tax unrealized losses for marketable debt securities at June 30, 2022 and December 31, 2021 were caused by fluctuations in interest rates and are temporary in nature. We review our marketable debt securities to identify and evaluate investments that have indications of possible impairment. Factors considered in determining whether a loss is other-than-temporary include the length of time and extent to which fair value has been less than the cost basis, the investment grade credit quality of our debt securities and our ability and intent to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value. At June 30, 2022 there were 171 marketable debt securities in an unrealized loss position, with the largest loss for any single security being equal to approximately $14,000. No marketable securities were sold in the three and six months ended June 30, 2022. We received proceeds from the sale of marketable securities of $225,000 in the three and six months ended June 30, 2021. The gain recognized on the sale was insignificant. See Note 6 for additional information regarding the fair value of our investments in marketable securities.   

Investments in marketable debt securities classified as cash equivalents of $4.9 million at June 30, 2022 and $8.8 million at December 31, 2021, consist of commercial money market savings accounts, corporate debt securities and certificates of deposit. There were no unrealized gains or losses associated with any of these securities at June 30, 2022 or December 31, 2021.

Cash and marketable securities held by foreign subsidiaries totaled $618,000 at June 30, 2022 and $588,000 at December 31, 2021.

6. FAIR VALUE MEASUREMENTS: 

We determine the fair value of our assets and liabilities based on the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value maximize the use of observable inputs and minimize the use of unobservable inputs. We use a fair value hierarchy with three levels of inputs, of which the first two are considered observable and the last is considered unobservable, to measure fair value. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1). The next highest priority is based on observable inputs other than Level 1 inputs including quoted prices for similar assets or liabilities in active markets or quoted prices for identical or similar assets or liabilities in less active markets or other observable inputs (Level 2). The lowest priority is given to unobservable inputs (Level 3). The following provides information regarding fair value measurements for our marketable securities as of June 30, 2022 and December 31, 2021 according to the three-level fair value hierarchy:

9

	Fair Value Measurements at June 30, 2022 Using
(In thousands)	Balance June 30,  2022		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Marketable securities:
U.S. government and agency obligations	$	14,039	$	—	$	14,039	$	—
Corporate debt securities and certificates of deposit	10,658		—		10,658		—
Asset backed securities	3,147		—		3,147		—
Equity security	31		31		—		—
Total marketable securities	$	27,875	$	31	$	27,844	$	—

	Fair Value Measurements at December 31, 2021 Using
(In thousands)	Balance December 31, 2021		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Marketable securities:
U.S. government and agency obligations	$	12,887	$	—	$	12,887	$	—
Corporate debt securities and certificates of deposit	9,043		—		9,043		—
Asset backed securities	2,635		—		2,635		—
Equity security	43		43		—		—
Total marketable securities	$	24,608	$	43	$	24,565	$	—

During the six months ended June 30, 2022 and the year ended December 31, 2021, we owned no Level 3 securities and there were no transfers within the three level hierarchy. A significant transfer is recognized when the inputs used to value a security have been changed which merit a transfer between the levels of the valuation hierarchy.       

The fair value for our U.S. government and agency obligations, corporate debt securities and certificates of deposit and asset backed securities are determined based on valuations provided by external investment managers who obtain them from a variety of industry standard data providers. The fair value for our equity security is based on a quoted market price obtained from an active market. The carrying amounts of financial instruments included in cash equivalents approximate their related fair values due to the short-term maturities of those instruments. See Note 5 for additional information regarding our investments in marketable securities.

Non-financial assets such as equipment and leasehold improvements, goodwill and intangible assets and right-of-use assets for operating leases are subject to non-recurring fair value measurements if they are deemed impaired. We had no re-measurements of non-financial assets to fair value in the six months ended June 30, 2022 or the six months ended June 30, 2021.

7. SHARE-BASED COMPENSATION:

We have three share-based compensation plans that are administered by the Compensation Committee of the Board of Directors. We have (a) an Employee Stock Incentive Plan for officers, other employees, consultants and independent contractors under which we have granted options and restricted stock units to officers and other employees, (b) an Employee Stock Purchase Plan under which shares of our common stock may be acquired by employees at discounted prices, and (c) a Non-Employee Director Stock Plan that provides for automatic grants of restricted shares of our common stock to non-employee directors. New shares of our common stock are issued upon stock option exercises, vesting of restricted stock units, issuances of shares to board members and issuances of shares under the Employee Stock Purchase Plan. 

Employee Stock Incentive Plan

As of June 30, 2022, there were 387,507 shares of common stock reserved in the aggregate for issuance pursuant to future awards under our Employee Stock Incentive Plan and 383,351 shares of common stock reserved in the aggregate for issuance pursuant to outstanding awards under such plan. Although our Compensation Committee has authority to issue options, restricted stock, restricted stock units, share grants and other share-based benefits under our Employee Stock Incentive Plan, to date only restricted stock units and stock options have been granted under the plan. Options have been granted at an option price per share equal to the market value of our common stock on the date of grant, vest over a four year period and expire seven years after the date of grant. Restricted stock units vest over a four year period and entitle the holders to one share of our common stock for each restricted stock unit. Reserved shares underlying outstanding awards, including options and restricted stock units, that are forfeited are available under the Employee Stock Incentive Plan for future grant.

Non-Employee Director Stock Plan

As of June 30, 2022, there were 28,000 shares of common stock reserved in the aggregate for issuance pursuant to future restricted share grants under our Non-Employee Director Stock Plan and 8,000 shares of common stock reserved in the aggregate for issuance pursuant to outstanding stock option awards under our Non-Employee Director Stock Plan (which previously authorized the granting of stock options to non-employee directors). Under the terms of the plan, each non-employee director receives annual restricted share grants of 2,000 shares of our common stock on the date of each annual meeting at which such director is elected to serve on the board. The annual restricted share grants of common stock vest in four equal quarterly installments during the year after the grant date, provided the non-employee director is still serving as a director on the applicable vesting date. 

On the date of our 2022 annual meeting, we issued 8,000 shares of our common stock to our non-employee directors, which were restricted as specified in the Non-Employee Director Stock Plan. The shares granted at the 2022 annual meeting had an aggregate fair market value on the date of grant equal to $336,000 (grant date fair value of $42.03 per share). As of June 30, 2022, none of these shares were vested. The aggregate fair value of the 8,000 unvested shares based on the closing price of our common stock on June 30, 2022 was $280,000. 

Stock Option Activity

The following is a summary of stock option activity in the six months ended June 30, 2022:

	Options Outstanding		Weighted Average Exercise Price Per Share
Outstanding, December 31, 2021	351,825		$	18.11
Exercised	(14,375	)	17.30
Outstanding, June 30, 2022	337,450		$	18.14
Exercisable, June 30, 2022	242,651		$	14.67

11

The intrinsic value of an option is the amount by which the market price of the underlying common stock exceeds the option's exercise price. For options outstanding at June 30, 2022, the weighted average remaining contractual term of all outstanding options was 2.93 years and their aggregate intrinsic value was $5.9 million. At June 30, 2022, the weighted average remaining contractual term of options that were exercisable was 2.07 years and their aggregate intrinsic value was $4.9 million. The aggregate intrinsic value of stock options exercised was $314,000 in the six months ended June 30, 2022 and $87,000 in the six months ended June 30, 2021. We received proceeds from stock option exercises of $239,000 in the six months ended June 30, 2022 and $67,000 in the six months ended June 30, 2021. No stock options vested in the six months ended June 30, 2022 or the six months ended June 30, 2021. No stock options were granted, forfeited or expired in the six months ended June 30, 2022. 

Restricted Shares and Restricted Stock Units 

There were 8,000 restricted shares granted under our Non-Employee Director Stock Plan in the six months ended June 30, 2022. Restricted stock units are granted under our Employee Stock Incentive Plan. The fair value of restricted shares and restricted stock units is equal to the fair market value of our common stock on the date of grant. The aggregate fair value of outstanding restricted shares and restricted stock units based on the closing share price of our common stock as of June 30, 2022 was $2.2 million. The aggregate fair value of restricted shares and restricted stock units that vested, based on the closing price of our common stock on the vesting date, was $159,000 in the six months ended June 30, 2022 and $115,000 in the six months ended June 30, 2021.  

The following is a summary of activity in restricted shares and restricted stock units in the six months ended June 30, 2022:

Restricted shares and restricted stock units	Shares		Weighted Average Grant Date Fair Value
Non-vested at December 31, 2021	57,901		$	28.21
Granted - restricted shares	8,000		42.03
Vested	(4,000	)	27.96
Non-vested at June 30, 2022	61,901		$	30.02

No restricted stock units were granted or forfeited in the six months ended June 30, 2022. No restricted shares were forfeited in the six months ended June 30, 2022.

Employee Stock Purchase Plan

We have an Employee Stock Purchase Plan available to eligible U.S. employees. Under the terms of the plan, eligible employees may designate from 1% to 10% of their compensation to be withheld through payroll deductions, up to a maximum of $6,500 in each plan year, for the purchase of common stock at 85% of the lower of the market price on the first or last day of the offering period (which begins on August 1st and ends on July 31st of each year). There were no shares purchased under this plan in the six months ended June 30, 2022. As of June 30, 2022, 129,411 shares remain available for future purchase under the Employee Stock Purchase Plan.   

Share-Based Compensation Information 

All share-based payments to employees and non-employee directors, including grants of stock options, restricted stock units and restricted shares, are required to be recognized as an expense in our consolidated statements of income based on the grant date fair value of the award. We utilize the straight-line method of expense recognition over the award's service period for our graded vesting options. The fair value of stock options has been determined using the Black-Scholes model. We account for the impact of forfeitures related to employee share-based payment arrangements when the forfeitures occur. We have classified employee share-based compensation within our consolidated statements of income in the same manner as our cash-based employee compensation costs. 

Pre-tax share-based compensation expense in the three months ended June 30, 2022 totaled $373,000, and included $126,000 for stock options, $34,000 for our Employee Stock Purchase Plan, $141,000 for restricted stock units and $72,000 for restricted shares. Pre-tax share-based compensation expense in the six months ended June 30, 2022 totaled $726,000, and included $249,000 for stock options, $68,000 for our Employee Stock Purchase Plan, $282,000 for restricted stock units and $127,000 for restricted shares. 

Pre-tax share-based compensation expense in the three months ended June 30, 2021 totaled $337,000, and included $125,000 for stock options, $31,000 for our Employee Stock Purchase Plan, $124,000 for restricted stock units and $57,000 for restricted shares. Pre-tax share-based compensation expense in the six months ended June 30, 2021 totaled $671,000, and included $248,000 for stock options, $63,000 for our Employee Stock Purchase Plan, $247,000 for restricted stock units and $113,000 for restricted shares.

At June 30, 2022, the total unrecognized compensation cost related to non-vested share-based compensation arrangements was $2.5 million and the related weighted average period over which such cost is expected to be recognized was 2.44 years.

Warranty costs:  

We provide for the estimated cost of product warranties, which cover products for periods ranging from one to three years, at the time revenue is recognized. While we engage in extensive product quality programs and processes, including actively monitoring and evaluating the quality of components provided by suppliers, warranty obligations do arise. These obligations are affected by product failure rates, the costs of materials used in correcting product failures and service delivery expenses incurred to make these corrections. If actual product failure rates and material or service delivery costs differ from our estimates, revisions to the estimated warranty liability are required and could be material. At the end of each reporting period, we revise our estimated warranty liability based on these factors. The current portion of our warranty liability is included as a component of accrued expenses. The long-term portion of our warranty liability is included as a component of other liabilities.

12. NET INCOME PER SHARE: 

Net income per basic share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Net income per diluted share is computed by dividing net income by the weighted average number of common and common equivalent shares outstanding during the period. Common equivalent shares consist of common shares to be issued upon exercise of stock options, vesting of restricted stock units, vesting of restricted shares and from purchases of shares under our Employee Stock Purchase Plan, as calculated using the treasury stock method. Common equivalent shares are excluded from the calculation of net income per diluted share if their effect is anti-dilutive. The components of net income per basic and diluted share were as follows:

(In thousands except per share amounts)	Net Income		Weighted Average Shares Outstanding	Per Share Amount
Three Months Ended June 30, 2022

14. INCOME TAXES:

We recorded income tax expense of $632,000 in the three months ended June 30, 2022, compared to an income tax expense of $590,000 in the three months ended June 30, 2021. We recorded income tax expense of $1.1 million in the six months ended June 30, 2022, compared to income tax expense of $901,000 in the six months ended June 30, 2021. Income tax expense in the six months ended June 30, 2022 reflected an effective tax rate of 12%, compared to an effective tax rate of 17% in the six months ended June 30, 2021. The reduction in the effective income tax rate in the six months ended June 30, 2022, when compared to the six months ended June 30, 2021, was mainly due to enhanced benefits from Foreign Derived Intangible Income (FDII) and Global Intangible Low-Taxed Income (GILTI), resulting from a change in U.S. income tax law requiring capitalization and subsequent amortization of U.S. based R&D expenditures over five years and foreign based R&D expenditures over 15 years. This change increased the income which is eligible for the FDII and GILTI benefits. The change in the treatment of R&D expenditures for income tax purposes is expected to have a favorable impact on our effective tax rate in 2022, but will most likely increase the amount of cash we expend for income taxes in the short term, particularly in 2023 and later years. On a recurring basis, our effective income tax rate is favorably impacted by the U.S. federal R&D tax credit, foreign tax credit, FDII and GILTI. 

We have deferred tax assets as a result of temporary differences between the taxable income on our tax returns and U.S. GAAP income, R&D tax credit carry forwards and state net operating loss carry forwards. A deferred tax asset generally represents future tax benefits to be received when temporary differences previously reported in our consolidated financial statements become deductible for income tax purposes, when net operating loss carry forwards could be applied against future taxable income, or when tax credit carry forwards are utilized on our tax returns. We assess the realizability of our deferred tax assets and the need for a valuation allowance based on the guidance provided in current financial accounting standards.  

Significant judgment is required in determining the realizability of our deferred tax assets. The assessment of whether valuation allowances are required considers, among other matters, the nature, frequency and severity of any current and cumulative losses, forecasts of future profitability, the duration of statutory carry forward periods, our experience with credit and loss carry forwards not expiring unused and tax planning alternatives. In analyzing the need for valuation allowances, we first considered our history of cumulative operating results for income tax purposes over the past three years in each of the tax jurisdictions in which we operate, our financial performance in recent quarters, statutory carry forward periods and tax planning alternatives. In addition, we considered both our near-term and long-term financial outlook. After considering all available evidence (both positive and negative), we concluded that recognition of valuation allowances for substantially all of our U.S. and Singapore based deferred tax assets was not required at June 30, 2022 or December 31, 2021.

The Inland Revenue Authority of Singapore is performing a routine compliance review of our 2018 income tax return. We presently anticipate that the outcome of this audit will not have a significant impact on our financial position or results of operations. 

15. CONTINGENCIES: 

We are periodically a defendant in miscellaneous lawsuits, claims and disputes in the ordinary course of business. While the outcome of these matters cannot be predicted with certainty, management presently believes the disposition of these matters will not have a material effect on our financial position, results of operations or cash flows. 

In the normal course of business to facilitate sales of our products and services, we at times indemnify other parties, including customers, with respect to certain matters. In these instances, we have agreed to hold the other parties harmless against losses arising out of intellectual property infringement or other types of claims. These agreements may limit the time within which an indemnification claim can be made, and almost always limits the amount of the claim. It is not possible to determine the maximum potential amount of exposure under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. Historically, payments made, if any, under these agreements have not had a material impact on our operating results, financial position or cash flows. However, there can be no assurance that intellectual property infringement and other claims against us or parties we have indemnified will not have a greater impact in the future.

RESULTS OF OPERATIONS

General 

We are a leading global developer and manufacturer of high precision 3D sensors and system products for inspection and metrology. We also develop and manufacture our WaferSense® products, which is a family of wireless, wafer-shaped sensors that provide measurements of critical factors in the semiconductor fabrication process. We intend to leverage our sensor technologies in the SMT and semiconductor industries to deliver profitable growth. A key element of our strategy is the continued development and sale of high precision 3D sensors and system products based on our proprietary Multi-Reflection Suppression™ (MRS™) technology. We believe that our MRS technology is a breakthrough 3D optical technology for high-end inspection and metrology with the potential to significantly expand our markets. Another key element in our strategy is the continued development and introduction of new sensor applications for our WaferSense® family of products.

We believe that conditions in the SMT and semiconductor capital equipment markets have been favorable, and we believe market conditions will remain solid for the remainder of 2022. Over the longer-term (i.e. the next several years), we expect a growing number of opportunities in the markets for SMT and semiconductor inspection and metrology. We believe that our 3D MRS sensor and system products and our WaferSense family of products have the potential to expand our presence in the markets for SMT and semiconductor capital equipment.

Manufacturing yield challenges, as electronics and semiconductors become more complex, are driving the need for more precise inspection and metrology. We believe 3D inspection and metrology represent high-growth segments in both the SMT and semiconductor capital equipment markets. We believe our 3D MRS technology platform is well suited for many applications in these markets, particularly with respect to complex circuit boards and semiconductor wafer and advanced packaging inspection and metrology applications. We are taking advantage of current market trends by deploying our 3D MRS sensor technology in the following products: 

· Our SQ3000™ and SQ3000+™ Multi-Function systems for Automated Optical Inspection (AOI), Solder Paste Inspection (SPI) and coordinate measurement (CMM) applications, which are designed to expand our presence in markets requiring high precision inspection and metrology. In these markets, identifying defects has become highly challenging and critical due to smaller semiconductor and electronics packaging and increasing component density on circuit boards. The SQ3000+ Multi-Function system with its higher resolution MRS sensor that inhibits reflection-based distortions caused by shiny components and surfaces is capable of measuring feature sizes down to 50 microns and is specifically designed for high-end inspection and metrology applications including advanced packaging, mini-LED and advanced SMT for high-end electronics. We believe our 3D MRS sensor technology is uniquely suited for many of these applications because of its ability to offer microscopic image quality and superior measurement performance at production line speeds. 

· Our next generation ultra-high resolution three micron pixel 3D NanoResolution MRS™ sensor, which is capable of measuring feature sizes down to 25 microns accurately and at high speeds, and is suitable for many semiconductor wafer and advanced packaging inspection and metrology applications. We have adapted the software used in our SQ3000 Multi-Function systems to work with wafer handling equipment to facilitate sales of our 3D NanoResolution MRS sensor to OEM's and system integrators.

· Our next generation MX3000™ AOI system for 3D inspection of memory modules following the singulation step of the manufacturing process. Two of the world's three largest memory manufacturers and their subcontractors have now purchased our MX3000 system. Additional orders for memory module inspection are expected in future periods, and we believe the potential market opportunity for our MX3000 system and 3D MRS sensors for memory module inspection is significant.

· Our WX3000™ metrology and inspection system for semiconductor wafer and advanced packing applications, which incorporates our next generation ultra-high resolution 3D NanoResolution MRS sensor, performs 100% 3D and 2D inspection and metrology simultaneously at high speeds and delivers through-put of more than 25 wafers per hour. The WX3000 is suitable for many high volume semiconductor wafer and advanced packaging inspection and metrology applications for feature sizes down to 25-microns. We recently received our first purchase order for the WX3000 and anticipate that sales of sensors and systems for semiconductor wafer and advanced packaging inspection and metrology will provide us with long-term growth opportunities. 

Revenue from our MRS-based products, including 3D AOI systems and high precision 3D MRS sensors, increased by $5.5 million or 26% to $26.8 million in the six months ended June 30, 2022, from $21.3 million in the six months ended June 30, 2021. Over the long term, we anticipate continued increases in sales of products based on our MRS technology in the SMT and semiconductor capital equipment markets. In particular, we believe inspection and metrology for mini LED, memory modules and semiconductor wafer and advanced packaging applications represent significant long-term growth opportunities. We anticipate increasing sales of MRS-based products by selling them to new OEM customers and system integrators, and by expanding direct sales of inspection and metrology system products to end-user customers. 

We have continued to invest in our WaferSense family of products, because fabricators of semiconductors and other customers view these products as valuable tools for improving yields and productivity. We have recently introduced several new WaferSense products to further increase our revenue growth, and additional WaferSense applications are currently under development, including Automatic Teaching Sensors (ATS) in both wafer and reticle formats and products for wafer edge detection. Over the long-term, strong future sales growth is anticipated for our WaferSense family of products. 

21

Our order backlog was $55.5 million at June 30, 2022, compared to $47.3 million at December 31, 2021 and $45.3 million at June 30, 2021. We believe that conditions in the SMT and semiconductor capital equipment markets have been favorable, and we believe market conditions will remain solid for the remainder of 2022. However, an increase in the severity of the current Covid-19 pandemic, an escalation in the Ukraine conflict or an economic recession or depression, could cause a slow-down in demand for SMT and semiconductor capital equipment. Over the long term, we believe anticipated sales growth of our products based on 3D MRS technology and WaferSense sensors should increase revenues and net income. We believe that we have the resources required to attain our growth objectives, given our available cash and marketable securities balances totaling $36.8 million at June 30, 2022.

Impact from Covid-19

Effect of Covid-19 Outbreak on Business Operations 

The Covid-19 outbreak has not had a significant impact on our business to date. Our revenues increased by 21% to $51.8 million in the first six months of 2022, from $42.9 million in the six months of 2021. The potential impact of Covid-19 on our business, results of operations, liquidity and prospects in the future is not fully known at this time. The following factors related to the Covid-19 outbreak may affect our business in the future:  

· Sales of some products, mainly our SQ3000 Multi-Function systems and MX memory module inspection products, require customer acceptance due to performance or other criteria that is considered more than a formality. Global travel restrictions and quarantine measures could hinder our ability to obtain customer acceptances in a timely manner in the future, and therefore impact the timing of revenue recognition. In addition, government mandated shelter-in-place orders or quarantine measures could cause delays in our ability to deliver our products to customers, or cause customers to delay purchases of our products, negatively impacting our revenue and profitability.

· Certain operating expenses were reduced in 2021 due to the Covid-19 pandemic. Travel, trade show expenses and other costs were reduced due to changes in employee travel patterns and trade show cancellations. Travel, trade show expenses and other costs have started to increase in those parts of the world where the Covid-19 pandemic is easing. 

·
The Covid-19 pandemic has caused disruptions in the global supply chain, including shortages of raw materials, parts and labor, and shipping and logistics issues, including delays in ocean freight and port congestion.  Increases in the cost of components, labor and freight could negatively impact our profitability in the future if we are unable to recover these costs by charging more for the products we sell. The inability to obtain adequate supply of components or labor could result in the inability to meet customer demands and delivery of one or more of our products for a period of several months or longer, negatively impacting our revenue and profitability. Supply chain disruptions are expected to continue for the foreseeable future and may increase if the pandemic worsens or continues for an extended period of time.   

Although we cannot estimate the continuing impact of the Covid-19 outbreak at this time, it may have an adverse effect on our results of future operations, financial position and liquidity. We believe that we have the resources required to meet any unforeseen difficulties resulting from the Covid-19 pandemic. We will continue to closely monitor the Covid-19 pandemic and its impact on our business in the coming months. 

Revenues

Our revenues increased by 9% to $27.6 million in the three months ended June 30, 2022, from $25.2 million in the three months ended June 30, 2021. Our revenues increased by 21% to $51.8 million in the six months ended June 30, 2022, from $42.9 million in the six months ended June 30, 2021. The following table sets forth revenues by product line for the three and six months ended June 30, 2022 and 2021:

	Three Months Ended June 30,							Six Months Ended June 30,
(In thousands)	2022		2021		% Change			2022		2021		% Change
High Precision 3D and 2D Sensors	$	6,826	$	7,131		(4	)%	$	14,887	$	13,488		10	%
Inspection and Metrology Systems		13,331		12,581		6	%		22,759		18,920		20	%
Semiconductor Sensors		7,412		5,492		35	%		14,169		10,528		35	%
Total	$	27,569	$	25,204		9	%	$	51,815	$	42,936		21	%

22

Revenues from sales of high precision 3D and 2D sensors decreased by $305,000 or 4% to $6.8 million in the three months ended June 30, 2022, and increased by $1.4 million or 10% to $14.9 million in the six months ended June 30, 2022 The decrease in the three months ended June 30, 2022 reflects normal fluctuations in demand from OEM customers for legacy 2D sensors. The increase in the six months ended June 30, 2022 was due to higher sales of both 3D MRS sensors and legacy 2D sensors resulting from favorable conditions in the global semiconductor and SMT capital equipment markets. Sales of high precision 3D MRS sensors increased by $459,000 or 11% to $4.8 million in the three months ended June 30, 2022, and increased by $1.1 million or 13% to $9.7 million in the six months ended June 30, 2022.

Sales of high precision 3D and 2D sensors are dependent on the success of our OEM customers and system integrators selling products that incorporate our sensors. We believe sales of our 3D MRS sensors, including our next generation ultra-high resolution three micron pixel 3D NanoResolution MRS sensor, will represent an increasing percentage of our total high precision 3D and 2D sensor sales in the future. Sales of high precision 3D and 2D sensors, including 3D MRS sensors, are prone to significant quarterly fluctuations due to variations in market demand and customer inventory levels.  

Revenues from sales of inspection and metrology systems increased by $750,000 or 6% to $13.3 million in the three months ended June 30, 2022, and increased by $3.8 million or 20% to $22.8 million in the six months ended June 30, 2022. The increases were due to record sales of SQ3000™ Multi-Function systems resulting from favorable conditions in the global semiconductor and SMT capital equipment markets, the competitive advantages offered by our 3D MRS sensor technology and companies transitioning away from 2D to 3D AOI systems to meet the increasingly demanding product inspection and metrology requirements in the SMT and semiconductor markets. Sales of SQ3000™ Multi-Function systems increased by $2.0 million or 33% to $8.3 million in the three months ended June 30, 2022, and increased by $3.9 million or 38% to $14.2 million in the six months ended June 30, 2022. Sales of memory module inspection systems decreased by $663,000 or 28% to $1.7 million in the three months ended June 30, 2022, and increased by $364,000 or 15% to $2.8 million in the six months ended June 30, 2022.  Sales of memory module inspection systems are prone to significant fluctuations on a quarterly basis.

The market transition away from 2D AOI systems is expected to result in an industry-wide compound annual rate of growth in global sales of 3D AOI systems of almost 20% through 2025. Given these market dynamics and because of the competitive advantages of our 3D MRS sensor technology, we anticipate sales of SQ3000 Multi-Function systems will represent an increasing percentage of our total inspection and metrology system sales in the future.

We believe memory manufacturers have determined that post singulation automated optical inspection of memory modules is an important step in their manufacturing process to improve yields and product quality. Two of the world’s three largest memory manufacturers and their subcontractors have now purchased the MX3000 system. At June 30, 2022, our backlog of orders for memory module inspection systems totaled $9.3 million, and we expect to recognize these orders as revenue over the balance of 2022. Additional orders for memory module inspection are expected in future periods, and we believe the potential market opportunity for our MX3000 system and 3D MRS sensors for memory module inspection is significant.

Revenues from sales of semiconductor sensors, principally our WaferSense line of products, increased by $1.9 million or 35% to $7.4 million in the three months ended June 30, 2022, and increased by $3.6 million or 35% to $14.2 million in the six months ended June 30, 2022. The revenue increase was due to construction of new semiconductor fabs, favorable market conditions for semiconductor capital equipment spending, and growing acceptance of our WaferSense products as important productivity enhancement tools by semiconductor manufacturers and capital equipment suppliers. Over the long term, we anticipate that the benefits from growing market awareness of our WaferSense products, improved account penetration at major semiconductor manufacturers and capital equipment suppliers and new product introductions will lead to additional WaferSense product sales. 

Export revenues totaled $21.8 million or 79% of our revenues in the three months ended June 30, 2022, compared to $21.2 million or 84% of our revenues in the three months ended June 30, 2021. Export revenues totaled $42.3 million or 82% of our revenues in the six months ended June 30, 2022, compared to $35.7 million or 83% of our revenues in the six months ended June 30, 2021. Export revenues as a percentage of total revenues decreased in the three and six months ended June 30, 2022 due to higher sales of SQ3000™ Multi-Function systems in the United States. 

Cost of Revenues and Gross Margin 

Cost of revenues increased only slightly in the three months ended June 30, 2022, and increased by $3.4 million or 14% to $26.8 million in the six months ended June 30, 2022. The increase in cost of revenues in the six months ended June 30, 2022 was mainly due to higher revenues, which increased on a year-over-year basis by 21%. Total gross margin as a percentage of revenues was 49% in the three months ended June 30, 2022, compared to 44% in the three months ended June 30, 2021. Total gross margin as a percentage of revenues was 48% in the six months ended June 30, 2022, compared to 45% in the six months ended June 30, 2021. Higher margin WaferSense sensors represented a larger percentage of our total revenues in the three and six months ended June 30, 2022 when compared to the three and six months ended June 30, 2021. 

23

Our markets are highly price competitive, particularly in the electronics assembly and SMT markets. As a result, we have experienced continual pressure on our gross margins. We compensate for the pressure to reduce the price of our products by introducing new products with more features and improved performance and through manufacturing cost reduction programs. Sales of many products that we have recently introduced or are about to introduce, including our SQ3000+ Multi-Function system, WX3000 system for semiconductor wafer and advanced packaging inspection and metrology, next generation 3D MRS sensors and semiconductor sensors (consisting primarily of our WaferSense line of products) have, or are expected to have, more favorable gross margins than many of our existing products. Our next generation 3D MRS sensor and system products are being designed for more complex and demanding inspection and metrology applications in the SMT and semiconductor markets. Sales prices and gross profit margins for these applications tend to be higher than margins for products sold in the general purpose SMT market. However, the gross margin percentage for our 3D MX3000 system for inspection of memory modules is lower than our current total gross margin percentage due to the significant costs for material handling and automation required for this product.  Our total gross margin percentage would most likely be negatively impacted in the future if sales of our 3D MX3000 become a larger share of our total revenue mix.

The Covid-19 pandemic has caused disruptions in the global supply chain, including shortages of raw materials, parts and labor, and shipping and logistics issues, including delays in ocean freight and port congestion. Increases in the cost of components, labor and freight could negatively impact our gross margins in the future if we are unable to recover these costs by charging more for the products we sell. 

Operating Expenses

R&D expenses were $3.1 million or 11% of revenues in the three months ended June 30, 2022, compared to $2.8 million or 11% of revenues in the three months ended June 30, 2021. R&D expenses were $6.0 million or 12% of revenues in the six months ended June 30, 2022, compared to $5.5 million or 13% of revenues in the six months ended June 30, 2021. The increase in R&D expenses in the three and six months ended June 30, 2022 was mainly due to higher compensation costs for new and existing R&D employees, and consulting services for ongoing R&D projects. Current R&D expenditures are primarily focused on development of a new 2D sensor, 3D MRS sensors and systems and WaferSense sensors, including enhancements to existing products and development of next generation products.  

Selling, general and administrative ("S,G&A") expenses were $5.4 million or 19% of revenues in the three months ended June 30, 2022, compared to $4.7 million or 19% of revenues in the three months ended June 30, 2021. Selling, general and administrative expenses were $10.1 million or 19% of revenues in the six months ended June 30, 2022, compared to $8.6 million or 20% of revenues in the six months ended June 30, 2021. The increase in S,G&A expenses in the three and six months ended June 30, 2022 was mainly due to higher compensation costs for new and existing S,G&A employees, higher third party channel commissions resulting from the 21% year-over-year increase in our revenues, and higher spending for trade shows.

Interest Income and Other

Interest income and other includes interest earned on investments and gains and losses associated with foreign currency transactions, primarily intercompany financing transactions associated with our international subsidiaries. We recognized gains from foreign currency transactions of $59,000 in the three months ended June 30, 2022, compared to losses from foreign currency transactions of $1,000 in the three months ended June 30, 2021. We recognized gains from foreign currency transactions of $113,000 in the six months ended June 30, 2022, compared to losses from foreign currency transactions of $53,000 in the six months ended June 30, 2021.

Income Taxes

We recorded income tax expense of $632,000 in the three months ended June 30, 2022, compared to income tax expense of $590,000 in the three months ended June 30, 2021. We recorded income tax expense of $1.1 million in the six months ended June 30, 2022, compared to income tax expense of $901,000 in the six months ended June 30, 2021. Income tax expense in the six months ended June 30, 2022 reflected an effective tax rate of 12%, compared to an effective tax rate of 17% in the six months ended June 30, 2021. The reduction in the effective income tax rate in both the three and six months ended June 30, 2022, when compared to the three and six months ended June 30, 2021, was mainly due to enhanced benefits from Foreign Derived Intangible Income (FDII) and Global Intangible Low-Taxed Income (GILTI), resulting from a change in U.S. income tax law requiring capitalization and subsequent amortization of U.S. based R&D expenditures over five years and foreign based R&D expenditures over 15 years. This change increased the income which is eligible for the FDII and GILTI benefits. The change in the treatment of R&D expenditures for income tax purposes is expected to have a favorable impact on our effective tax rate in 2022, but will most likely increase the amount of cash we expend for income taxes in the short term, particularly in 2023 and later years. On a recurring basis, our effective income tax rate is favorably impacted by the U.S. federal R&D tax credit, foreign tax credit, FDII and GILTI.

Liquidity and Capital Resources

Our cash and cash equivalents decreased by $4.8 million in the six months ended June 30, 2022. Cash used in operating activities totaled $110,000. Investing activities had purchases of marketable securities totaling $9.1 million and purchases of fixed assets and capitalized patent costs totaling $980,000, which were partially offset by proceeds of $5.1 million from maturities of marketable securities. Financing activities had proceeds of $238,000 from stock option exercises. Our cash and cash equivalents fluctuate in part because of sales and maturities of marketable securities and investment of cash balances in marketable securities, and from other sources of cash. Accordingly, we believe the combined balances of cash and marketable securities provide a more reliable indication of our available liquidity than cash balances alone. Combined balances of cash and marketable securities decreased by approximately $1.5 million to $36.8 million as of June 30, 2022, from $38.3 million as of December 31, 2021.

Operating activities used $110,000 of cash in the six months ended June 30, 2022. The amount of cash provided by operations was favorably impacted by our net income of $8.0 million. Net income was affected favorably by non-cash items totaling $2.4 million for depreciation and amortization, non-cash operating lease expense, provision for doubtful accounts, deferred taxes, non-cash gains from foreign currency transactions, share-based compensation costs and an unrealized loss on our available-for-sale equity security. Changes in operating assets and liabilities providing cash included an increase in accounts payable of $2.7 million and an increase in advance customer payments of $79,000. Changes in operating assets and liabilities using cash included an increase in accounts receivable of $8.4 million, an increase in inventories of $2.7 million, an increase in prepaid expenses and other assets of $1.2 million, a decrease in accrued expenses of $597,000 and a decrease in operating lease liabilities of $429,000. Increases in accounts payable and inventories at June 30, 2022 were due to planned purchases of raw materials to meet anticipated customer demand and new product introductions. Advance customer payments were up due to an increase in deposits for equipment prior to transfer of control. The increase in accounts receivable was mainly due to higher sales in the second quarter of 2022 when compared to the fourth quarter of 2021. The increase in prepaid expenses and other assets was due to higher balances of refundable goods and services tax and deposits paid for inventory. The decrease in accrued expenses was mainly due to payment of 2021 bonus accruals in the first quarter of 2022. The decrease in operating lease liabilities was due to monthly rental payments for facility leases. 

Investing activities used $5.0 million of cash in the six months ended June 30, 2022. Changes in the level of investment in marketable securities, resulting from purchases and maturities of those securities, used $4.0 million of cash in the six months ended June 30, 2022. We used $980,000 of cash in the six months ended June 30, 2022 for the purchase of fixed assets and capitalized patent costs.    

Financing activities provided $238,000 of cash in the six months ended June 30, 2022 from the exercise of employee stock options. 

At June 30, 2022, we did not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities. These entities are established by some companies for the purpose of establishing off-balance sheet arrangements or for other contractually narrow or limited purposes.

We believe that on-hand cash, cash equivalents and marketable securities, coupled with anticipated future cash flow from operations, will be adequate to fund our cash flow needs for the foreseeable future.

Critical Accounting Policies and Estimates

Our discussion and analysis of financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles for interim financial statements. The preparation of these consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate these estimates, including estimates related to revenue recognition, bad debts, warranty obligations, inventory valuation, intangible assets, and income taxes. We base these estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Our actual results may differ from these estimates under different assumptions or conditions. See our Annual Report on Form 10-K for the year December 31, 2021 for additional discussion regarding critical accounting policies and estimates, and the judgements we believe have the most effect on our reported financial position and results of operations.

ITEM 3 – QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Not applicable.

ITEM 4 – CONTROLS AND PROCEDURES

a.          Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”)). Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective in ensuring that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in applicable rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, in a manner that allows timely decisions regarding required disclosure. 

b.         There was no change in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during the period covered by this quarterly report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1 – LEGAL PROCEEDINGS

None.

ITEM 1A – RISK FACTORS

In addition to the other information set forth in this report, you should carefully consider the risk factors discussed in Part I “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2021. The risks identified in these risk factors could materially affect our business, financial condition or future results.  The risks described in our Annual Report on Form 10-K are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently believe are immaterial could have a material adverse effect on our business, financial condition and/or operating results. Other than as noted below, there were no material changes to the risk factors disclosed in “Part I, Item 1A Risk Factors” of our Form 10-K for the year ended December 31, 2021.

RISKS RELATED TO MERGER

Our proposed Merger may not be completed on a timely basis, or at all, and the failure to complete or delays in completing the Merger could adversely affect our business, financial results or stock price.

On August 8, 2022, we announced that we entered into the Merger Agreement with Nordson and Merger Sub, which provided that Nordson will acquire all of our outstanding shares of no par value stock at a price of $54.00 per share in cash. Subject to the terms and conditions of the Merger Agreement, Merger Sub will be merged with and into the Company with the Company surviving the Merger as a wholly-owned subsidiary of Nordson. The Merger is subject to a number of customary conditions set forth in the Merger Agreement, including the approval of our shareholders and receipt of regulatory approval, which are not within our control.  We can provide no assurance as to when, or if, the conditions to the closing of the Merger will be satisfied or waived, that other events will not intervene to delay or result in the termination of the Merger, or that the Merger will be consummated or consummated in the timeframe or manner currently anticipated.

The Merger, including any delay in closing or failure to close, could have a negative impact on our business and financial results as well as our relationships with our customers, suppliers or employees, and could have a negative impact on our ability to pursue alternative strategic transactions and/or our ability to implement our business plans.

Any delay in closing or failure to close the Merger could have a negative impact on our stock price.

ITEM 2 – UNREGISTERED SALES OF EQUITY SECURITIES, USE OF PROCEEDS AND ISSUER PURCHASES OF EQUITY SECURITIES 

We withhold common shares to cover employee tax withholding obligations from the exercise of stock options. In the six months ended June 30, 2022, we withheld 29 shares to satisfy employee tax withholding requirements of $1,100.

ITEM 3 – DEFAULTS UPON SENIOR SECURITIES

None.

ITEM 4 – MINE SAFETY DISCLOSURES 

None.

ITEM 5 – OTHER INFORMATION

None.

Interim Reporting

1. INTERIM REPORTING:

The interim condensed consolidated financial statements of CyberOptics Corporation and its wholly-owned subsidiaries ("we", "us" or "our") presented herein as of June 30, 2022, and for the three and six month periods ended June 30, 2022 and 2021, are unaudited but, in the opinion of management, include all adjustments, consisting of normal recurring adjustments necessary, for a fair presentation of financial position, results of operations and cash flows for the periods presented.

The results of operations for the three and six month periods ended June 30, 2022 do not necessarily indicate the results to be expected for the full year. The December 31, 2021 consolidated balance sheet data was derived from audited consolidated financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America ("U.S. GAAP"). The unaudited interim condensed consolidated financial statements should be read in conjunction with our consolidated financial statements and notes thereto contained in our Annual Report on Form 10-K for the year ended December 31, 2021.

Covid-19 Pandemic

2. COVID-19 PANDEMIC:

Effect of Covid-19 Outbreak on Business Operations

The Covid-19 outbreak has not had a significant impact on our business to date. The potential impact of Covid-19 on our business, results of operations, liquidity and prospects in the future is not fully known at this time.  The following factors related to the Covid-19 outbreak may affect our business in the future:

· Sales of some products, mainly our SQ3000 Multi-Function systems and MX memory module inspection products, require customer acceptance due to performance or other criteria that is considered more than a formality. Global travel restrictions and quarantine measures could hinder our ability to obtain customer acceptances in a timely manner in the future, and therefore impact the timing of revenue recognition. In addition, government mandated shelter-in-place orders or quarantine measures could cause delays in our ability to deliver our products to customers, or cause customers to delay purchases of our products, negatively impacting our revenue and profitability.

·
The Covid-19 pandemic has caused disruptions in the global supply chain, including shortages of raw materials, parts and labor, and shipping and logistics issues, including delays in ocean freight and port congestion. The inability to obtain adequate supply of components or labor could result in the inability to meet customer demands and delivery of one or more of our products for a period of several months or longer, negatively impacting our revenue and profitability. Supply chain disruptions are expected to continue for the foreseeable future and may increase if the pandemic worsens or continues for an extended period of time. 

Although we cannot estimate the continuing impact of the Covid-19 outbreak at this time, it may have an adverse effect on our results of future operations, financial position and liquidity.

Recent Accounting Developments

3. RECENT ACCOUNTING DEVELOPMENTS: 

In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments, which revises guidance for the accounting for credit losses on financial instruments within its scope, and in November 2018, issued ASU No. 2018-19, which amended the standard. The new standard introduces an approach to estimating credit losses that is based on expected losses (referred to as the current expected credit losses model), and applies to most financial assets measured at amortized cost and certain other instruments, including available-for-sale marketable debt securities, trade and other receivables. The new standard is effective for us on January 1, 2023, with early adoption permitted. We are required to apply the standard's provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. We presently do not believe the new standard will have a material impact on our consolidated financial statements. 

No other new accounting pronouncements are expected to have a significant impact on our consolidated financial statements.

See Note 11 for additional information regarding disaggregation of revenue. 

Contract Balances

Contract assets consist of unbilled amounts from sales where we recognize the revenue over time and the revenue recognized exceeds the amount billed to the customer at a point in time. Accounts and trade notes receivable are recorded when the right to payment becomes unconditional. Contract liabilities consist of payments received in advance of performance under the contract. Contract liabilities are recognized as revenue when we perform under the contract.   

The following summarizes our contract assets and contract liabilities:     

(In thousands)	June 30, 2022		December 31, 2021
Contract assets, included in other current assets	$	171	$	7
Contract liabilities - advance customer payments	$	359	$	289
Contract liabilities - deferred warranty revenue	$	454	$	445

Changes in contract assets in the six months ended June 30, 2022 and the six months ended June 30, 2021 resulted from unbilled amounts under sensor product arrangements and longer duration 3D scanning service projects in which revenue is recognized over time. Changes in contract liabilities primarily resulted from reclassification of beginning contract liabilities to revenue as performance obligations were satisfied or from cash received in advance and not recognized as revenue. See Note 9 for changes in contractual obligations related to deferred warranty revenue. Unsatisfied performance obligations for deferred warranty revenue are generally expected to be recognized as revenue over the next one to three years. There were no impairment losses for contract assets in the six months ended June 30, 2022 or the six months ended June 30, 2021.  

The following summarizes the amounts reclassified from beginning contract liabilities to revenue:  

	Three Months Ended June 30,					Six Months Ended June 30,

Our long-term investments in marketable debt securities all have maturities of less than five years. Net pre-tax unrealized losses for marketable debt securities of $662,000 at June 30, 2022 and $43,000 at December 31, 2021 have been recorded as a component of accumulated other comprehensive loss in stockholders’ equity. We only invest in highly rated investment grade debt securities. We have determined that the net pre-tax unrealized losses for marketable debt securities at June 30, 2022 and December 31, 2021 were caused by fluctuations in interest rates and are temporary in nature. We review our marketable debt securities to identify and evaluate investments that have indications of possible impairment. Factors considered in determining whether a loss is other-than-temporary include the length of time and extent to which fair value has been less than the cost basis, the investment grade credit quality of our debt securities and our ability and intent to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value. At June 30, 2022 there were 171 marketable debt securities in an unrealized loss position, with the largest loss for any single security being equal to approximately $14,000. No marketable securities were sold in the three and six months ended June 30, 2022. We received proceeds from the sale of marketable securities of $225,000 in the three and six months ended June 30, 2021. The gain recognized on the sale was insignificant. See Note 6 for additional information regarding the fair value of our investments in marketable securities.   

Investments in marketable debt securities classified as cash equivalents of $4.9 million at June 30, 2022 and $8.8 million at December 31, 2021, consist of commercial money market savings accounts, corporate debt securities and certificates of deposit. There were no unrealized gains or losses associated with any of these securities at June 30, 2022 or December 31, 2021.

Cash and marketable securities held by foreign subsidiaries totaled $618,000 at June 30, 2022 and $588,000 at December 31, 2021.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

6. FAIR VALUE MEASUREMENTS: 

We determine the fair value of our assets and liabilities based on the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value maximize the use of observable inputs and minimize the use of unobservable inputs. We use a fair value hierarchy with three levels of inputs, of which the first two are considered observable and the last is considered unobservable, to measure fair value. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1). The next highest priority is based on observable inputs other than Level 1 inputs including quoted prices for similar assets or liabilities in active markets or quoted prices for identical or similar assets or liabilities in less active markets or other observable inputs (Level 2). The lowest priority is given to unobservable inputs (Level 3). The following provides information regarding fair value measurements for our marketable securities as of June 30, 2022 and December 31, 2021 according to the three-level fair value hierarchy:

	Fair Value Measurements at June 30, 2022 Using
(In thousands)	Balance June 30,  2022		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Marketable securities:
U.S. government and agency obligations	$	14,039	$	—	$	14,039	$	—
Corporate debt securities and certificates of deposit	10,658		—		10,658		—

Equity security	31		31		—		—
Total marketable securities	$	27,875	$	31	$	27,844	$	—

	Fair Value Measurements at December 31, 2021 Using
(In thousands)	Balance December 31, 2021		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Marketable securities:
U.S. government and agency obligations	$	12,887	$	—	$	12,887	$	—
Corporate debt securities and certificates of deposit	9,043		—		9,043		—
Asset backed securities	2,635		—		2,635		—
Equity security	43		43		—		—
Total marketable securities	$	24,608	$	43	$	24,565	$	—

During the six months ended June 30, 2022 and the year ended December 31, 2021, we owned no Level 3 securities and there were no transfers within the three level hierarchy. A significant transfer is recognized when the inputs used to value a security have been changed which merit a transfer between the levels of the valuation hierarchy.       

The fair value for our U.S. government and agency obligations, corporate debt securities and certificates of deposit and asset backed securities are determined based on valuations provided by external investment managers who obtain them from a variety of industry standard data providers. The fair value for our equity security is based on a quoted market price obtained from an active market. The carrying amounts of financial instruments included in cash equivalents approximate their related fair values due to the short-term maturities of those instruments. See Note 5 for additional information regarding our investments in marketable securities.

Non-financial assets such as equipment and leasehold improvements, goodwill and intangible assets and right-of-use assets for operating leases are subject to non-recurring fair value measurements if they are deemed impaired. We had no re-measurements of non-financial assets to fair value in the six months ended June 30, 2022 or the six months ended June 30, 2021.

Share-Based Compensation

Share-based Compensation [Abstract]

Share-Based Compensation

7. SHARE-BASED COMPENSATION:

We have three share-based compensation plans that are administered by the Compensation Committee of the Board of Directors. We have (a) an Employee Stock Incentive Plan for officers, other employees, consultants and independent contractors under which we have granted options and restricted stock units to officers and other employees, (b) an Employee Stock Purchase Plan under which shares of our common stock may be acquired by employees at discounted prices, and (c) a Non-Employee Director Stock Plan that provides for automatic grants of restricted shares of our common stock to non-employee directors. New shares of our common stock are issued upon stock option exercises, vesting of restricted stock units, issuances of shares to board members and issuances of shares under the Employee Stock Purchase Plan. 

Employee Stock Incentive Plan

As of June 30, 2022, there were 387,507 shares of common stock reserved in the aggregate for issuance pursuant to future awards under our Employee Stock Incentive Plan and 383,351 shares of common stock reserved in the aggregate for issuance pursuant to outstanding awards under such plan. Although our Compensation Committee has authority to issue options, restricted stock, restricted stock units, share grants and other share-based benefits under our Employee Stock Incentive Plan, to date only restricted stock units and stock options have been granted under the plan. Options have been granted at an option price per share equal to the market value of our common stock on the date of grant, vest over a four year period and expire seven years after the date of grant. Restricted stock units vest over a four year period and entitle the holders to one share of our common stock for each restricted stock unit. Reserved shares underlying outstanding awards, including options and restricted stock units, that are forfeited are available under the Employee Stock Incentive Plan for future grant.

Non-Employee Director Stock Plan

As of June 30, 2022, there were 28,000 shares of common stock reserved in the aggregate for issuance pursuant to future restricted share grants under our Non-Employee Director Stock Plan and 8,000 shares of common stock reserved in the aggregate for issuance pursuant to outstanding stock option awards under our Non-Employee Director Stock Plan (which previously authorized the granting of stock options to non-employee directors). Under the terms of the plan, each non-employee director receives annual restricted share grants of 2,000 shares of our common stock on the date of each annual meeting at which such director is elected to serve on the board. The annual restricted share grants of common stock vest in four equal quarterly installments during the year after the grant date, provided the non-employee director is still serving as a director on the applicable vesting date. 

On the date of our 2022 annual meeting, we issued 8,000 shares of our common stock to our non-employee directors, which were restricted as specified in the Non-Employee Director Stock Plan. The shares granted at the 2022 annual meeting had an aggregate fair market value on the date of grant equal to $336,000 (grant date fair value of $42.03 per share). As of June 30, 2022, none of these shares were vested. The aggregate fair value of the 8,000 unvested shares based on the closing price of our common stock on June 30, 2022 was $280,000. 

Stock Option Activity

The following is a summary of stock option activity in the six months ended June 30, 2022:

	Options Outstanding		Weighted Average Exercise Price Per Share
Outstanding, December 31, 2021	351,825		$	18.11
Exercised	(14,375	)	17.30
Outstanding, June 30, 2022	337,450		$	18.14
Exercisable, June 30, 2022	242,651		$	14.67

Restricted Shares and Restricted Stock Units 

There were 8,000 restricted shares granted under our Non-Employee Director Stock Plan in the six months ended June 30, 2022. Restricted stock units are granted under our Employee Stock Incentive Plan. The fair value of restricted shares and restricted stock units is equal to the fair market value of our common stock on the date of grant. The aggregate fair value of outstanding restricted shares and restricted stock units based on the closing share price of our common stock as of June 30, 2022 was $2.2 million. The aggregate fair value of restricted shares and restricted stock units that vested, based on the closing price of our common stock on the vesting date, was $159,000 in the six months ended June 30, 2022 and $115,000 in the six months ended June 30, 2021.  

The following is a summary of activity in restricted shares and restricted stock units in the six months ended June 30, 2022:

Restricted shares and restricted stock units	Shares		Weighted Average Grant Date Fair Value
Non-vested at December 31, 2021	57,901		$	28.21
Granted - restricted shares	8,000		42.03
Vested	(4,000	)	27.96
Non-vested at June 30, 2022	61,901		$	30.02

No restricted stock units were granted or forfeited in the six months ended June 30, 2022. No restricted shares were forfeited in the six months ended June 30, 2022.

Employee Stock Purchase Plan

We have an Employee Stock Purchase Plan available to eligible U.S. employees. Under the terms of the plan, eligible employees may designate from 1% to 10% of their compensation to be withheld through payroll deductions, up to a maximum of $6,500 in each plan year, for the purchase of common stock at 85% of the lower of the market price on the first or last day of the offering period (which begins on August 1st and ends on July 31st of each year). There were no shares purchased under this plan in the six months ended June 30, 2022. As of June 30, 2022, 129,411 shares remain available for future purchase under the Employee Stock Purchase Plan.   

Share-Based Compensation Information 

All share-based payments to employees and non-employee directors, including grants of stock options, restricted stock units and restricted shares, are required to be recognized as an expense in our consolidated statements of income based on the grant date fair value of the award. We utilize the straight-line method of expense recognition over the award's service period for our graded vesting options. The fair value of stock options has been determined using the Black-Scholes model. We account for the impact of forfeitures related to employee share-based payment arrangements when the forfeitures occur. We have classified employee share-based compensation within our consolidated statements of income in the same manner as our cash-based employee compensation costs. 

Pre-tax share-based compensation expense in the three months ended June 30, 2022 totaled $373,000, and included $126,000 for stock options, $34,000 for our Employee Stock Purchase Plan, $141,000 for restricted stock units and $72,000 for restricted shares. Pre-tax share-based compensation expense in the six months ended June 30, 2022 totaled $726,000, and included $249,000 for stock options, $68,000 for our Employee Stock Purchase Plan, $282,000 for restricted stock units and $127,000 for restricted shares. 

Pre-tax share-based compensation expense in the three months ended June 30, 2021 totaled $337,000, and included $125,000 for stock options, $31,000 for our Employee Stock Purchase Plan, $124,000 for restricted stock units and $57,000 for restricted shares. Pre-tax share-based compensation expense in the six months ended June 30, 2021 totaled $671,000, and included $248,000 for stock options, $63,000 for our Employee Stock Purchase Plan, $247,000 for restricted stock units and $113,000 for restricted shares.

At June 30, 2022, the total unrecognized compensation cost related to non-vested share-based compensation arrangements was $2.5 million and the related weighted average period over which such cost is expected to be recognized was 2.44 years.

Warranty costs:  

We provide for the estimated cost of product warranties, which cover products for periods ranging from one to three years, at the time revenue is recognized. While we engage in extensive product quality programs and processes, including actively monitoring and evaluating the quality of components provided by suppliers, warranty obligations do arise. These obligations are affected by product failure rates, the costs of materials used in correcting product failures and service delivery expenses incurred to make these corrections. If actual product failure rates and material or service delivery costs differ from our estimates, revisions to the estimated warranty liability are required and could be material. At the end of each reporting period, we revise our estimated warranty liability based on these factors. The current portion of our warranty liability is included as a component of accrued expenses. The long-term portion of our warranty liability is included as a component of other liabilities.    

A reconciliation of the changes in our estimated warranty liability is as follows:

Earnings Per Share [Abstract]

Net Income Per Share

12. NET INCOME PER SHARE: 

Net income per basic share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Net income per diluted share is computed by dividing net income by the weighted average number of common and common equivalent shares outstanding during the period. Common equivalent shares consist of common shares to be issued upon exercise of stock options, vesting of restricted stock units, vesting of restricted shares and from purchases of shares under our Employee Stock Purchase Plan, as calculated using the treasury stock method. Common equivalent shares are excluded from the calculation of net income per diluted share if their effect is anti-dilutive. The components of net income per basic and diluted share were as follows:

(In thousands except per share amounts)	Net Income		Weighted Average Shares Outstanding	Per Share Amount
Three Months Ended June 30, 2022
Basic	$	4,389	7,404	$	0.59
Dilutive effect of common equivalent shares	—		199	(0.01		)

Dilutive effect of common equivalent shares	—		194	(0.01		)
Dilutive	$	4,550	7,490	$	0.61

Potentially dilutive shares consist of stock options, restricted stock units, restricted shares and purchases of shares under our Employee Stock Purchase Plan. Potentially dilutive shares excluded from the calculations of net income per diluted share due to their anti-dilutive effect were as follows: 24,000 shares in the three months ended June 30, 2022; 47,000 shares in the six months ended June 30, 2022; 47,000 shares in the three months ended June 30, 2021; 72,000 shares in the six months ended June 30, 2021.

Income Tax Disclosure [Abstract]

Income Taxes

14. INCOME TAXES:

We recorded income tax expense of $632,000 in the three months ended June 30, 2022, compared to an income tax expense of $590,000 in the three months ended June 30, 2021. We recorded income tax expense of $1.1 million in the six months ended June 30, 2022, compared to income tax expense of $901,000 in the six months ended June 30, 2021. Income tax expense in the six months ended June 30, 2022 reflected an effective tax rate of 12%, compared to an effective tax rate of 17% in the six months ended June 30, 2021. The reduction in the effective income tax rate in the six months ended June 30, 2022, when compared to the six months ended June 30, 2021, was mainly due to enhanced benefits from Foreign Derived Intangible Income (FDII) and Global Intangible Low-Taxed Income (GILTI), resulting from a change in U.S. income tax law requiring capitalization and subsequent amortization of U.S. based R&D expenditures over five years and foreign based R&D expenditures over 15 years. This change increased the income which is eligible for the FDII and GILTI benefits. The change in the treatment of R&D expenditures for income tax purposes is expected to have a favorable impact on our effective tax rate in 2022, but will most likely increase the amount of cash we expend for income taxes in the short term, particularly in 2023 and later years. On a recurring basis, our effective income tax rate is favorably impacted by the U.S. federal R&D tax credit, foreign tax credit, FDII and GILTI. 

We have deferred tax assets as a result of temporary differences between the taxable income on our tax returns and U.S. GAAP income, R&D tax credit carry forwards and state net operating loss carry forwards. A deferred tax asset generally represents future tax benefits to be received when temporary differences previously reported in our consolidated financial statements become deductible for income tax purposes, when net operating loss carry forwards could be applied against future taxable income, or when tax credit carry forwards are utilized on our tax returns. We assess the realizability of our deferred tax assets and the need for a valuation allowance based on the guidance provided in current financial accounting standards.  

Significant judgment is required in determining the realizability of our deferred tax assets. The assessment of whether valuation allowances are required considers, among other matters, the nature, frequency and severity of any current and cumulative losses, forecasts of future profitability, the duration of statutory carry forward periods, our experience with credit and loss carry forwards not expiring unused and tax planning alternatives. In analyzing the need for valuation allowances, we first considered our history of cumulative operating results for income tax purposes over the past three years in each of the tax jurisdictions in which we operate, our financial performance in recent quarters, statutory carry forward periods and tax planning alternatives. In addition, we considered both our near-term and long-term financial outlook. After considering all available evidence (both positive and negative), we concluded that recognition of valuation allowances for substantially all of our U.S. and Singapore based deferred tax assets was not required at June 30, 2022 or December 31, 2021.

The Inland Revenue Authority of Singapore is performing a routine compliance review of our 2018 income tax return. We presently anticipate that the outcome of this audit will not have a significant impact on our financial position or results of operations.

Contingencies

15. CONTINGENCIES: 

We are periodically a defendant in miscellaneous lawsuits, claims and disputes in the ordinary course of business. While the outcome of these matters cannot be predicted with certainty, management presently believes the disposition of these matters will not have a material effect on our financial position, results of operations or cash flows. 

In the normal course of business to facilitate sales of our products and services, we at times indemnify other parties, including customers, with respect to certain matters. In these instances, we have agreed to hold the other parties harmless against losses arising out of intellectual property infringement or other types of claims. These agreements may limit the time within which an indemnification claim can be made, and almost always limits the amount of the claim. It is not possible to determine the maximum potential amount of exposure under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. Historically, payments made, if any, under these agreements have not had a material impact on our operating results, financial position or cash flows. However, there can be no assurance that intellectual property infringement and other claims against us or parties we have indemnified will not have a greater impact in the future.

16. SUBSEQUENT EVENT:

On August 7, 2022, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Nordson Corporation (“Nordson”) and Meta Merger Company, a wholly owned subsidiary of Nordson (“Merger Sub”), pursuant to which, subject to the satisfaction or waiver of certain conditions, Merger Sub will merge with and into the Company (the ”Merger”). As a result of the Merger, Merger Sub will cease to exist and the Company will survive as a wholly owned subsidiary of Nordson. The Merger is presently expected to close not later than the fourth quarter of calendar year 2022, subject to customary closing conditions, including, without limitation, (i) the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”) and (ii) the requisite shareholder approval being received.

Pursuant to the Merger Agreement, upon the consummation of the Merger (the “Effective Time”), each share of the Company’s no par value common stock issued and outstanding immediately prior to the Effective Time, other than dissenting shares, will be converted into the right to receive $54.00 in cash.  The Merger Agreement contains customary representations and covenants that we must observe, including certain interim operating covenants that may restrict our operations during the pendency of the Merger, subject to certain exceptions. If the Merger is completed, certain change of control and severance provisions of our compensation arrangements will be triggered at the Effective Time. In addition, the Merger Agreement also contains certain termination rights that may require us to pay Nordson a $12.5 million termination fee. For additional details of the Merger and the terms thereof, refer to the Merger Agreement, a copy of which is included as Exhibit 2.1 to our Current Report on Form 8-K filed with the Securities and Exchange Commission on August 8, 2022.

Accounting Policies [Abstract]

Recent Accounting Developments

In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments, which revises guidance for the accounting for credit losses on financial instruments within its scope, and in November 2018, issued ASU No. 2018-19, which amended the standard. The new standard introduces an approach to estimating credit losses that is based on expected losses (referred to as the current expected credit losses model), and applies to most financial assets measured at amortized cost and certain other instruments, including available-for-sale marketable debt securities, trade and other receivables. The new standard is effective for us on January 1, 2023, with early adoption permitted. We are required to apply the standard's provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. We presently do not believe the new standard will have a material impact on our consolidated financial statements. 

No other new accounting pronouncements are expected to have a significant impact on our consolidated financial statements.
