COMPANY OVERVIEW
BUSINESS BACKGROUND
We are one of the world's leading providers of laser solutions and optics for microelectronics, life sciences, industrial manufacturing, scientific and aerospace and defense markets. More than a provider of lasers, we deliver systems to the world's leading brands, innovators, and researchers, all backed with a global service and support network. Since inception in 1966, we have grown through internal expansion and through strategic acquisitions of complementary businesses, technologies, intellectual property, manufacturing processes and product offerings. We are organized into two reporting segments: OEM Laser Sources ("OLS") and Industrial Lasers & Systems ("ILS"), based on the organizational structure of the company and how the chief operating decision maker ("CODM") receives and utilizes information provided to allocate resources and make decisions. This segmentation reflects the go-to-market strategies and synergies for our broad portfolio of laser technologies and products. While both segments deliver cost-effective, highly reliable photonics solutions, the OLS business segment is focused on high performance laser sources and complex optical sub-systems typically used in microelectronics manufacturing, medical diagnostics and therapeutic applications, as well as in scientific research. Our ILS business segment delivers high performance laser sources, sub-systems and machine tools primarily used for industrial laser materials processing, serving important end markets like automotive, machine tools, consumer goods and medical device manufacturing as well as applications in aerospace and defense. Income (loss) from operations is the measure of profit and loss that our CODM uses to assess performance and make decisions. Income (loss) from operations represents the net sales less the cost of sales and direct operating expenses incurred within the operating segments as well as allocated expenses such as shared sales and manufacturing costs. We do not allocate certain operating expenses to our operating segments and we manage them at the corporate level. These unallocated costs include stock-based compensation and corporate functions (certain management, finance, legal and human resources) and are included in Corporate and other. Management does not consider unallocated Corporate and other costs in its measurement of segment performance.
SIGNIFICANT EVENTS - MERGER
Merger Agreements and Termination Fee
OnJanuary 18, 2021 , we entered into an Agreement and Plan of Merger with Lumentum Holdings Inc. ("Lumentum"),Cheetah Acquisition Sub, Inc. ("Lumentum Merger Sub I") andCheetah Acquisition Sub LLC ("Lumentum Merger Sub II"), pursuant to which we agreed to be acquired for$100.00 in cash per Coherent share and 1.1851 shares of Lumentum common stock per Coherent share. In light of unsolicited proposals received from each of MKS Instruments, Inc. and II-VI Incorporated ("II-VI"), onMarch 9, 2021 , we entered into an Amended and Restated Agreement and Plan of Merger with Lumentum, Lumentum Merger Sub I and Lumentum Merger Sub II (the "Amended Lumentum Agreement"), pursuant to which we agreed to be acquired for$175.00 in cash per Coherent share and 1.0109 shares of Lumentum common stock per Coherent share. OnMarch 25, 2021 , we terminated the Amended Lumentum Agreement and entered into an Agreement and Plan of Merger with II-VI andWatson Merger Sub Inc. ("II-VI Merger Sub") (the "II-VI Merger Agreement"), pursuant to which we agreed to be acquired for$220.00 in cash per Coherent share and 0.91 of a share of II-VI common stock per Coherent share. In connection with terminating the Amended Lumentum Agreement, we paid a termination fee of$217.6 million to Lumentum during our second quarter of fiscal 2021. The termination fee, in addition to other costs related to the merger agreements with Lumentum and II-VI, is included in merger and acquisition costs in our condensed consolidated statements of operations. Pursuant to the terms of the II-VI Merger Agreement, the acquisition of Coherent will be accomplished through a merger of II-VI Merger Sub with and into Coherent (the "Merger"), with Coherent surviving the Merger as a wholly owned subsidiary of II-VI. Pursuant to the terms of the II-VI Merger Agreement, and subject to the terms and conditions set forth therein, at the effective time of the Merger (the "Effective Time"), each share of the common stock of Coherent (the "Coherent Common Stock") issued and outstanding immediately prior to the Effective Time (other than (x) shares of Coherent Common Stock owned by II-VI, Coherent, or any direct or indirect wholly owned subsidiary of II-VI or Coherent or (y) shares of Coherent Common Stock owned by stockholderswho have properly exercised and perfected appraisal rights underDelaware law, in each case, 30 -------------------------------------------------------------------------------- Table of Content s immediately prior to the Effective Time), will be cancelled and extinguished and automatically converted into the right to receive the following consideration:
(A)
(B) 0.91 of a validly issued, fully paid and non-assessable share of the common stock of II-VI.
The completion of the proposed Merger is subject to customary closing conditions, including, among others the expiration or termination of the required waiting periods under the HSR Act and regulatory approvals in applicable jurisdictions includingGermany ,China andSouth Korea . As previously disclosed, II-VI and Coherent refiled their respective HSR Notification onMay 2, 2022 . The HSR Notification, which triggers a 30-day review period, was made prior to the one-year expiration of II-VI's and Coherent's initial HSR Notification filed last year. II-VI and Coherent continue cooperative discussions with SAMR. Accordingly, other than the regulatory approval inChina andthe United States , there are no other open regulatory closing conditions to the proposed Merger. We anticipate that the closing of the Merger will occur prior toJune 30, 2022 . MARKET APPLICATIONS

APPLICATION OF CRITICAL ACCOUNTING POLICIES AND ESTIMATES
Our discussion and analysis of financial condition and results of operations are based upon our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted inthe United States of America and pursuant to the rules and regulations of theSEC . The preparation of these condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. We have identified the following as the items that require the most significant judgment and often involve complex estimation: revenue recognition, business combinations, accounting for long-lived assets (including goodwill and intangible assets), inventory valuation, warranty reserves and accounting for income taxes. See Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for our fiscal year endedOctober 2, 2021 . KEY PERFORMANCE INDICATORS
Below is a summary of some of the quantitative performance indicators (as defined below) that are evaluated by management to assess our financial performance. Some of the indicators are non-GAAP measures and should not be considered as an alternative to any other measure for determining operating performance or liquidity that is calculated in accordance with generally accepted accounting principles.

Net sales for the second quarter of fiscal 2022 increased 3.6% in our OLS segment and decreased 7.8% in our ILS segment from the same quarter one year ago. Net sales for the first six months of fiscal 2022 increased 9.2% in our OLS segment and increased 5.6% in our ILS segment from the same period one year ago. For a description of the reasons for changes in net sales refer to the "Results of Operations" section below.
Gross Profit as a Percentage of
Gross profit as a percentage of net sales ("gross profit percentage") is calculated as gross profit for the period divided by net sales for the period. Gross profit percentage in the second quarter of fiscal 2022 increased to 47.9% from 45.2% in our OLS segment and increased to 32.8% from 27.7% in our ILS segment as compared to the same quarter one year ago. Gross profit percentage in the first six months of fiscal 2022 increased to 49.1% from 45.2% in our OLS segment and increased to 33.2% from 25.6% in our ILS segment as compared to the same period one year ago. For a description of the reasons for changes in gross profit refer to the "Results of Operations" section below. 33
--------------------------------------------------------------------------------
Table of Content s
Research and Development as a Percentage of
Research and development as a percentage of net sales ("R&D percentage") is calculated as research and development expense for the period divided by net sales for the period. Management considers R&D percentage to be an important indicator in managing our business as investing in new technologies is a key to future growth. R&D percentage was 8.6% for the second quarter of fiscal 2022 and the same quarter one year ago and decreased to 8.1% for the first six months of fiscal 2022 from 8.6% for the same period one year ago. For a description of the reasons for changes in R&D spending refer to the "Results of Operations" section below.
Net Cash Provided by Operating Activities
Net cash provided by operating activities as reflected on our condensed consolidated statements of cash flows primarily represents the excess of cash collected from billings to our customers and other receipts over cash paid to our vendors for expenses and inventory purchases to run our business. We believe that cash flows from operations is an important performance indicator because cash generation over the long term is essential to maintaining a healthy business and providing funds to help fuel growth. Net cash provided by operating activities in the second quarter and first six months of fiscal 2021 was unfavorably impacted by merger and acquisition costs, including our payment of a termination fee of$217.6 million to Lumentum. For a description of the reasons for changes in net cash provided by operating activities refer to the "Liquidity and Capital Resources" section below.
Free Cash Flow
Free cash flow represents net cash provided by operating activities reduced by purchases of property and equipment, both as reflected on our condensed consolidated statements of cash flows. We believe that free cash flow is an important performance indicator because it is a measure of cash generation after accounting for cash outflows to support operations and maintain capital assets. Cash generation over the long term is essential to maintaining a healthy business and providing funds to help fuel growth. Free cash flow in the second quarter and first six months of fiscal 2021 was unfavorably impacted by merger and acquisition costs, including our payment of a termination fee of$217.6 million to Lumentum. For a description of the reasons for changes in free cash flow refer to the "Liquidity and Capital Resources" section below, where we discuss the reasons for changes in net cash provided by operating and investing activities.
Days Sales Outstanding in Receivables
We calculate days sales outstanding ("DSO") in receivables as net receivables at the end of the period divided by net sales during the period and then multiplied by the number of days in the period, using 90 days for quarters. DSO in receivables indicates how well we are managing our collection of receivables, with lower DSO in receivables resulting in higher working capital availability. The more money we have tied up in receivables, the less money we have available for research and development, acquisitions, expansion, marketing and other activities to grow our business. Our DSO in receivables for the second quarter of fiscal 2022 increased to 64 days from 60 days for the same quarter one year ago. The increase was primarily due to the delay in collections of certain receivables, which slipped toApril 2022 , partially due to the shutdown of all businesses inShanghai by the Chinese government at the end of the second quarter of fiscal 2022. In addition, we experienced a higher concentration of sales in the last month of the quarter endedApril 2, 2022 compared to the last month of the quarter endedApril 3, 2021 as well as a higher concentration of receivables with longer payment terms.
Annualized Second Quarter Inventory Turns
We calculate annualized second quarter inventory turns as the cost of sales during the second quarter annualized and divided by net inventories at the end of the second quarter. This indicates how well we are managing our inventory levels, with higher inventory turns resulting in more working capital availability and a higher return on our investments in inventory. Our annualized inventory turns for the second quarter of fiscal 2022 decreased to 2.1 turns from 2.4 turns for the same quarter a year ago primarily due to the favorable impact of foreign exchange rates and higher inventory levels, primarily in our ILS segment, resulting from higher purchases due to longer lead times and/or anticipated supply constraints. 34 -------------------------------------------------------------------------------- Table of Content s Adjusted EBITDA as a Percentage ofNet Sales We define adjusted EBITDA as operating income adjusted for depreciation, amortization, stock-based compensation expense, restructuring costs and certain other non-operating income and expense items, such as merger and acquisition costs. Key initiatives to reach our goals for EBITDA improvements include utilization of our manufacturing locations inAsia , optimizing our supply chain and continued leveraging of our infrastructure. We utilize a number of different financial measures, both GAAP and non-GAAP, such as free cash flow and adjusted EBITDA as a percentage of net sales, in analyzing and assessing our overall business performance, for making operating decisions and for forecasting and planning future periods. We consider the use of non-GAAP financial measures helpful in assessing our current financial performance and ongoing operations. While we use non-GAAP financial measures as a tool to enhance our understanding of certain aspects of our financial performance, we do not consider these measures to be a substitute for, or superior to, the information provided by GAAP financial measures. We provide free cash flow and adjusted EBITDA as a percentage of sales in order to enhance investors' understanding of our ongoing operations. These measures are used by some investors when assessing our performance.
Below is the reconciliation of our net cash provided by (used in) operating activities to our free cash flow:

The military conflict and the resulting sanctions have caused and are expected to continue to cause significant disruptions in logistics, availability of components and supplies used in the manufacture and services of our products and global markets. The largest source of certain gases which are utilized in the use and servicing of some of our products, including our largest excimer lasers, has historically been located inUkraine . We have accelerated purchases of this gas from other limited sources outside of the conflict and, to date, have avoided any material disruption to our business. Similarly, our end customers for these products are largely located in geographies which have access to these gases from local suppliers. 35 -------------------------------------------------------------------------------- Table of Content s Numerous logistic companies have meaningfully limited their capacity for shipping goods as a result of the closing of certain air and land routes related to the sanctions and conflict zones, which has resulted in significant increases in inbound and outbound shipment costs. As of the date hereof, it has been publicly reported thatRussia has been willing to leverage its supply of gasoline, oil and other fossil fuels in a manner which could greatly limit the availability thereof to the EU, includingGermany . Relatedly,Germany and other countries in the EU have announced their intention to meaningfully limit their importation of fuels which are supplied byRussia at some point in the future. We have managed through these situations and, to date, have not seen materially negative consequences from the foregoing. A material reduction in our access to critical gases, the disruption in the ability to source components and supplies used in the manufacture, service or use of our products and the availability of shipping and the increased costs therefor would likely negatively impact the results of our operations. Additionally, the consequences of the foregoing or other limitation on the availability of fuels to provide electricity in the EU to businesses at the same current levels could have a material adverse effect on our business, particularly with regards to our ability to manufacture and ship products at our manufacturing locations inGermany . We have historically had less than 1% of our revenues derived from customers inRussia orUkraine . Accordingly, compliance with the economic sanctions has not had a material adverse impact on our results of operations through the period reflected herein. As a result, based on available information to date, our estimate of potential future impairments on our businesses inRussia orUkraine related to customer sales would not be material with respect to our consolidated financial position. However, the conflict's continued impact of logistic and supply chain challenges could result in a materially negative impact on our results of operations in future periods.
Merger Agreement and related fees
See "Significant Events - Merger" above in this Item 2 for a description of the Agreement and Plan of Merger we entered into onJanuary 18, 2021 , and the Amended Lumentum Agreement we entered into onMarch 9, 2021 with Lumentum, Lumentum Merger Sub I and Lumentum Merger Sub II, the termination of the Amended Lumentum Agreement and the payment of a termination fee to Lumentum in the second quarter of fiscal 2021, as well as the II-VI Merger Agreement we entered into with II-VI and II-VI Merger Sub onMarch 25, 2021 .
The termination fee, in addition to other costs related to the merger agreements is included in merger and acquisition costs in our condensed consolidated statements of operations.
Coronavirus pandemic (COVID-19)
InDecember 2019 , COVID-19 cases were reported, and inJanuary 2020 , theWorld Health Organization ("WHO") declared it a Public Health Emergency of International Concern. OnFebruary 28, 2020 , theWHO raised its assessment of the COVID-19 threat from high to very high at a global level due to the continued increase in the number of cases and affected countries, and onMarch 11, 2020 , theWHO characterized COVID-19 as a pandemic. In an effort to contain COVID-19 or slow its spread, governments around the world have enacted various measures from time to time, including orders to close all businesses not deemed "essential," isolate residents in their homes or places of residence, and practice social distancing at and away from work. These actions and the global health crisis caused by COVID-19 will continue to negatively impact global business activity, which could negatively affect our revenue and results of operations. Each of the regions where we generate a majority of our revenue includingAsia ,Europe andNorth America have been and may continue to be impacted by COVID-19. The timing and extent of impact related to COVID-19 varies by country and region. Although we estimated that our sales for fiscal 2020 were negatively impacted by the COVID-19 pandemic, we believe the impact on sales in fiscal 2021 and the first two quarters of fiscal 2022 was immaterial. However, prolonged lockdowns inShanghai or any other major region inChina may impact portions of our supply chain and limit our ability to logistically fulfill customer commitments in future quarters, which would negatively impact our sales and margins. During fiscal 2020 and 2021, the global demand environment was uncertain at times given the effects of COVID-19 on many businesses, including manufacturing facilities and customer confidence around the world. In fiscal 2021, and continuing into fiscal 2022, we saw global demand recover in all regions and begin to return to a more normalized demand trend. However, we cannot predict future resurgences of COVID-19, particularly in light of the Delta and Omicron variants, and the impact that it 36 -------------------------------------------------------------------------------- Table of Content s may have on future demand for our products and services, particularly given the recent shutdown measures taken in certain countries inEurope andAsia , particularly inShanghai and other regions inChina . Currently, our major production facilities inEurope ,Asia , andthe United States remain open. At all of our locations, we have transitioned from business continuity plans to return-to-operations plans while continuing to maintain high standards of employee safety and sanitization protocols. Our Return to Operations Plans have a phased approach with the primary focus on employee safety, with a continuing requirement for "working from home" for other members of our workforce wherever possible. We have vertically integrated manufacturing, and many of the components produced at certain of our facilities supply other company facilities, are single sourced internally and are not available from third-party suppliers (for example our semiconductor diodes are manufactured inSunnyvale, California ). While we do maintain a safety stock of critical components at our various locations, the scope, timing, and duration of various government restrictions to address the COVID-19 pandemic could impact our internal supply chain. We have implemented certain policy changes to help support our employees impacted by COVID-19. These measures have and will continue to increase the cost of our operations but the magnitude and length of time of this impact is difficult to quantify at this time and may continue to be difficult to estimate in the future. If our sales are reduced for an extended period or if our production output falls because of government restrictions, we may be required to reduce payroll-related costs and other expenses in the future through layoffs or furloughs, even though we have not done so to date. We continue to experience various supply disruptions throughout the supply chain and are working closely with our supply base to mitigate or remove constraints as they become known. Supply constraints due to COVID-19 may impact the speed with which we are able to ramp up production if we experience strong demand for certain products. We also continue to face supply chain constraints primarily related to electronic components and freight cargo capacity limitations, including available air cargo space and higher freight rates. Available cargo space on flights between theU.S. andEurope , andEurope andAsia has been and remains limited as a result of the impact from COVID-19 and government and business responses to it, and this has increased shipping time and costs. As noted above, these logistical challenges have been exacerbated by theRussia /Ukraine conflict. In addition, shipments between countries have been more severely impacted by COVID-19 and we are experiencing delays due to additional checks at border crossings, including withinEurope andAsia . For example, we have seen significant delays for the importation of goods intoChina as a result of checks on containers for the presence of COVID-19. Government actions related to COVID-19 come on the heels of trade tensions betweenthe United States andChina , which may continue. We believe we have the ability to meet the near-term demand for our products, but the situation is fluid and subject to change. We continue to monitor the rapidly evolving conditions and circumstances as well as guidance from international and domestic authorities, including public health authorities, and we may need to take additional actions based on their recommendations. There is considerable uncertainty regarding the impact on our business stemming from current measures and potential future measures that could restrict access to our facilities, limit our manufacturing and support operations, and place restrictions on our workforce, customers, and suppliers. The measures implemented by various authorities related to the COVID-19 outbreak have caused us to change our business practices including those related to where employees work, the distance between employees in our facilities, limitations on in-person meetings between employees and with customers, suppliers, service providers, and stakeholders as well as restrictions on some shipping activities, business travel to domestic and international locations or to attend trade shows, investor conferences and other events. In March of 2020, we formed aCOVID Steering Committee to, among other things, propose, discuss, and implement best practices in response to COVID-19.The COVID Steering Committee meets weekly and more often if required. All of our executive officers and many of our key senior-level employees are members of theCOVID Steering Committee . The COVID-19 pandemic has significantly increased worldwide and regional economic uncertainty and, at times, decreased demand for our products in many markets we serve, which could continue for an unknown period of time. In these circumstances, there may be developments outside of our control, including the length and extent of the COVID-19 outbreak, government-imposed measures and our ability to ship as well as install products and/or service installed products that may require us to adjust our operating plans. As such, given the dynamic nature of this situation, we cannot estimate with certainty the future impacts of COVID-19 on our financial condition, results of operations or cash flows. However, we do expect that it could have an adverse impact on our revenue as well as our overall profitability and could lead to an increase in inventory provisions, allowances for credit losses, and a volatile effective tax rate driven by changes in the mix of earnings across our markets. In the second quarter of fiscal 2022, product material shortages and the lockdown of business and other activity in regions ofChina , includingShanghai , caused an unfavorable revenue impact of approximately$19 million spread across all markets, with our ILS segment impacted by$11 million and our OLS segment impacted by$8 million . 37 -------------------------------------------------------------------------------- Table of Content s See "Risks Related to COVID-19 Pandemic" in Part II, Item 1A of this quarterly report regarding the impact of COVID-19.
Restructuring
In the fourth quarter of fiscal 2020, we began a restructuring program in our ILS segment which included management reorganizations, the planned closure of certain manufacturing sites, and the right-sizing of global sales, service, order admin, marketing communication and certain administrative functions, among others. In the first and second quarters of fiscal 2022, we incurred benefits of$0.0 million and$2.3 million , respectively, primarily related to a gain from the sale of assets and other cost reimbursements partially offset by estimated severance, which is primarily recorded in selling, general and administrative expenses. In the first and second quarters of fiscal 2021, we incurred costs of$5.4 million and$3.6 million , respectively, primarily related to write-offs of excess inventory and accruals for vendor commitments, which are recorded in cost of sales, estimated severance and accelerated depreciation. The project is substantially complete as ofApril 2, 2022 .
See Note 19, "Restructuring Charges" in the Notes to Condensed Consolidated Financial Statements.

The following tables set forth, for the periods indicated, the amount of net sales and their relative percentages of total net sales by market application (dollars in thousands): Three Months Ended April 2, 2022 April 3, 2021 Percentage Percentage of total of total Amount net sales Amount net sales Consolidated: Microelectronics$ 160,360 43.3 %$ 168,277 45.0 % Precision manufacturing 104,407 28.2 % 107,398 28.7 % Instrumentation 90,239 24.4 % 88,333 23.6 % Aerospace and defense 15,198 4.1 % 9,974 2.7 % Total$ 370,204 100.0 %$ 373,982 100.0 % Six Months Ended April 2, 2022 April 3, 2021 Percentage Percentage of total of total Amount net sales Amount net sales Consolidated: Microelectronics$ 333,382 44.2 %$ 317,125 45.3 % Precision manufacturing 208,961 27.7 % 188,848 27.0 % Instrumentation 184,182 24.4 % 173,560 24.8 % Aerospace and defense 28,186 3.7 % 20,502 2.9 % Total$ 754,711 100.0 %$ 700,035 100.0 % Quarterly Net sales for the second quarter of fiscal 2022 decreased by$3.8 million , or 1%, compared to the second quarter of fiscal 2021, with decreases in the microelectronics and precision manufacturing markets partially offset by increases in the aerospace and defense and instrumentation markets. We finished fiscal 2021 with a positive book-to-bill ratio in all four end-markets, as well as increased backlog levels compared to fiscal 2020 across all end-markets. We also had a positive book-to-bill ratio in the first and second quarters of fiscal 2022. We believe that we are well-positioned with our laser-based technology to benefit from technology proliferation in rapid growth areas such as 5G, flexible OLED and MicroLED. In addition, we believe the market for laser-based medical instrumentation, devices and procedures will continue to grow with the increase of an aging population around the globe. Furthermore, we believe that technology advances will result in increased laser-based defense spending globally. The decrease in the microelectronics market of$7.9 million , or 5%, was primarily due to decreased shipments for flat panel display (primarily lower revenues from systems) and advanced packaging applications partially offset by higher shipments for semiconductor applications. In microelectronics, we expect future increases in ELA tool shipments as Asian manufacturers 39 -------------------------------------------------------------------------------- Table of Content s improve yields and ramp manufacturing as indicated by the fact that we received new orders for these products in both fiscal 2021 and the first two quarters of fiscal 2022. In addition, it is expected that the handset market will continue to transition to 5G and newer technologies over time. This technology requires more power from the battery which we expect will result in the handset manufacturers having to decide between shorter talk times or placement of larger batteries in existing form factors. Since OLED displays are much thinner than liquid crystal displays (LCD), we believe 5G will increase demand for OLED displays to accommodate larger batteries. In addition, we are seeing demand for laser solutions for MicroLED pilot production. We believe that these technological demands will allow us to continue to maintain a leadership position in flat panel display applications. We are also seeing strong demand for semiconductor applications, somewhat tempered by constraints in the supply chain for semiconductor chips. Demand is being driven by continuous strength in cloud computing and data centers as well as in advanced packaging applications driven by 5G demand for smaller geometry, better power management and next generation printed circuit boards. The decrease in the precision manufacturing market of$3.0 million , or 3%, was due to lower sales in machine tools and automotive applications partially offset by higher sales in medical and materials processing applications. The Purchasing Managers Index ("PMI") is a measure of the prevailing economic trends in manufacturing, and often correlates to materials processing sales. In the second quarter of fiscal 2022 compared to the prior quarter, decreases in the manufacturing PMI forChina andEurope were partially offset by increases in theU.S. Supply chain constraints continued in all regions due to both the shutdowns inChina and the Russian invasion ofUkraine . Although unfavorably impacted by the global semiconductor chip shortage, we expect continued strong demand for laser based welding products, especially for battery applications in EVs (Electronic Vehicles). Medical device manufacturing orders continued to be strong in the first two quarters of fiscal 2022 after record orders in fiscal 2021, particularly in theU.S. The increase in the instrumentation market of$1.9 million , or 2%, was due primarily to higher shipments for biomedical instrumentation applications partially offset by lower shipments for medical applications. We supply lasers and optical systems for biomedical instrumentation applications and our lasers have been used in diagnostic instruments in applications including gene sequencing, biomarker identification and vaccine development. We expect demand in scientific and government program applications to continue to fluctuate from quarter to quarter. Sales in the aerospace and defense ("A&D") market increased$5.2 million , or 52%, primarily due to higher shipments in aerospace and defense applications. We anticipate the A&D market, especially amplifiers for directed energy and specialty optics for aerospace, to be a multi-year growth opportunity for us.
Year-to-date
Net sales for the first six months of fiscal 2022 increased by$54.7 million , or 8%, compared to the first six months of fiscal 2021, with significant increases in the precision manufacturing and microelectronics markets and smaller increases in the instrumentation and aerospace and defense markets.

The increase in our OLS segment sales was primarily due to higher shipments for semiconductor and advanced packaging applications in the microelectronics market as well as biomedical instrumentation applications in the instrumentation market, medical applications in the precision manufacturing market and aerospace applications in the aerospace and defense market, partially offset by lower shipments for flat panel display systems in the microelectronics market. The sales increase in our ILS segment was primarily due to higher sales to the precision manufacturing market, primarily for materials processing, consumer goods and medical applications as well as higher sales for applications in the aerospace and defense market, partially offset by lower sales for advanced packaging applications within the microelectronics market.
GROSS PROFIT
Consolidated
Our gross profit percentage increased by 4.0% to 41.7% in the second quarter of fiscal 2022 from 37.7% in the second quarter of fiscal 2021 and increased by 5.4% to 42.7% in the first six months of fiscal 2022 from 37.3% in the first six months of fiscal 2021. 41
--------------------------------------------------------------------------------
Table of Content s
The 4.0% increase in gross profit percentage during the second quarter of fiscal 2022 included a 0.6% favorable impact of lower restructuring costs, primarily related to lower severance costs, lower write-offs of inventories and lower accelerated depreciation due to our closure of certain manufacturing sites and 0.4% lower amortization of intangibles. Additionally, gross profit percentage increased 3.0% compared to the second quarter of fiscal 2021 primarily due to favorable product margins (4.7%) partially offset by higher other costs (1.0%) and higher warranty costs (0.7%). Product margins were favorable in both OLS and ILS due to the impact of favorable absorption of manufacturing costs from higher sales volumes, higher capitalized variances, and the favorable impact of the weaker Euro against theU.S. Dollar. Additionally, the favorable impact of selective price increases for certain products and services and favorable mix in both OLS and ILS favorably impacted product margins, which was partially offset by increased pricing for electronic components due to global supply chain and logistical constraints, and fuel and expedited order surcharges. Other costs, excluding restructuring provisions, were higher primarily due to increased freight costs resulting from shipping constraints and fuel surcharges in both segments and higher inventory provisions in ILS. The higher warranty and installation costs as a percentage of sales were due to increased warranty events for fiber components and CO2 and global tools products in ILS and lower tube salvage in OLS. The 5.4% increase in gross profit percentage during the first six months of fiscal 2022 included a 1.0% favorable impact of lower restructuring costs, primarily related to lower severance costs due to our closure of certain manufacturing sites and 0.4% lower amortization of intangibles. Additionally, gross profit percentage increased 4.0% compared to the first quarter of fiscal 2021 primarily due to favorable product margins (4.8%) partially offset by higher other costs (0.6%) and higher warranty costs (0.2%). Product margins were favorable in both OLS and ILS due to the impact of favorable absorption of manufacturing costs from higher sales volumes, higher capitalized variances, and the favorable impact of the weaker Euro against theU.S. Dollar. Additionally, the favorable impact of selective price increases for certain products and services and favorable mix in both OLS and ILS, partially offset by increased pricing for electronic components due to global supply chain and logistical constraints, and fuel and expedited order surcharges, favorably impacted product margins. Other costs, excluding restructuring provisions, were higher primarily due to higher freight costs resulting from shipping constraints and fuel surcharges in both segments. The higher warranty and installation costs as a percentage of sales were due to increased warranty events in both ILS and OLS. Our gross profit percentage has been and will continue to be affected by a variety of factors including the impact of shipping volumes, product mix, pricing on volume orders, our ability to manufacture advanced and more complex products, manufacturing efficiencies, excess and obsolete inventory write-downs, warranty costs, amortization of intangibles, pricing by competitors or suppliers (including the impact of increased pricing on some of our critical supplies due to global supply chain and logistical constraints, and fuel and expedited order surcharges), new product introductions, production volume, customization and reconfiguration of systems, commodity prices and foreign currency fluctuations against theU.S. Dollar, particularly the recent volatility of the Euro and to a lesser extent, the Japanese Yen and South Korean Won.

INCOME TAXES
Our effective tax rates on income before income taxes for the three and six months endedApril 2, 2022 of 31.3% and 25.0%, respectively, were higher than theU.S. federal tax rate of 21% primarily due to the impact of income subject to foreign tax rates that are higher than theU.S. tax rates, limitations on the deductibility of compensation under Internal Revenue Code Section 162(m), stock-based compensation not deductible for tax purposes and the deferred taxes on foreign earnings not considered permanently reinvested. These amounts are partially offset by the benefit of federal research and development tax credits, the benefit of a foreign-derived intangible income deduction and ourSingapore tax exemption. Our effective tax rate for the six months endedApril 2, 2022 also reflected the excess tax benefits from restricted stock unit vesting. Our effective tax rates on loss before income taxes for the three and six months endedApril 3, 2021 of 20.4% and 14.1%, respectively, were lower than theU.S. federal tax rate of 21.0% primarily due to the benefit of federal research and development tax credits and ourSingapore tax exemption, partially offset by the establishment of valuation allowances for certain foreign deferred tax assets, the impact of income subject to foreign tax rates that are higher than theU.S. tax rates, the deferred taxes on foreign earnings not considered permanently reinvested, stock-based compensation not deductible for tax purposes and limitations on the deductibility of compensation under Internal Revenue Code Section 162(m).

Our current business plans do not demonstrate a need for additional foreign funds to support our domestic operations and it is our intention to repay our borrowings to our foreign subsidiaries. If, however, a portion of our foreign funds are needed for and distributed to our operations inthe United States via a dividend, we may be subject to additional foreign withholding taxes and 46 -------------------------------------------------------------------------------- Table of Content s certain state taxes. The amount of theU.S. and foreign taxes due would depend on the amount and manner of repatriation, as well as the location from where the funds are repatriated. We actively monitor the third-party depository institutions that hold these assets, primarily focusing on the safety of principal and secondarily maximizing yield on these assets. We diversify our cash and cash equivalents and investments among various financial institutions, money market funds and other securities in order to reduce our exposure should any one of these financial institutions or financial instruments fail or encounter difficulties. To date, we have not experienced any material loss or lack of access to our invested cash, cash equivalents or short-term investments. However, we can provide no assurances that access to our invested cash, cash equivalents or short-term investments will not be impacted by adverse conditions in the financial markets. To date, we have had sufficient liquidity to manage the financial impact of COVID-19. However, we can provide no assurance that this will continue to be the case if the impact of COVID-19 is prolonged or if there is an extended impact on us or the economy in general. Further, COVID-19 has caused significant uncertainty and volatility in the credit markets. If our liquidity or access to capital becomes significantly constrained, or if costs of capital increase significantly due to the impact of COVID-19 as result of a volatility in the capital markets, a reduction in our creditworthiness or other factors, then our financial condition, results of operations and cash flows could be materially adversely affected.

Sources and Uses of Cash
Historically, our primary source of cash has been provided by operations. Other sources of cash in the past few fiscal years include proceeds from our Euro Term Loan used to finance our acquisition of Rofin, proceeds received from the sale of our stock through our employee stock purchase plan as well as borrowings under our Revolving Credit Facility and for the construction of a facility inGermany . Our historical uses of cash have primarily been for acquisitions of businesses and technologies, the repurchase of our common stock, merger and acquisition costs, the purchases of property and equipment and debt issuance costs. Supplemental information pertaining to our historical sources and uses of cash is presented as follows and should be read in conjunction with our condensed consolidated statements of cash flows and the notes to condensed consolidated financial statements: Six Months EndedApril 2, 2022 April 3, 2021 (in thousands)
Net cash provided by (used in) operating activities
(68,319)
Issuance of shares under employee stock plans 6,566
5,896
Net settlement of restricted common stock (39,364)
(9,251)
Borrowings (repayments), net (14,692)
(5,160)
Purchases of property and equipment (35,002)
(37,045)
Net cash provided by operating activities increased by$107.1 million for the first six months of fiscal 2022 compared to the same period one year ago. The increase in cash provided by operating activities was primarily due to higher net income including non-cash adjustments and higher cash flows from deferred income taxes, partially offset by lower cash flows from accrued payroll, inventories, accounts payable, income taxes payable and other current liabilities. In order to support our liquidity during the pandemic, we have and will continue to take measures to increase available cash on hand, including, but not limited to, reducing discretionary spending for operating and capital expenses. To further support our liquidity, we elected to defer the payment of our employer portion of social security taxes beginning inApril 2020 and through the end of calendar 2020, which we have paid or expect to pay in equal installments in the first quarters of fiscal 2022 (paid) and 2023, as provided for under the CARES Act. We believe that our existing cash, cash equivalents and short term investments combined with cash to be provided by operating activities will be adequate to cover our working capital needs and planned capital expenditures for at least the next 12 months to the extent such items are known or are reasonably determinable based on current business and market conditions, including consideration of the impact of COVID-19, and will be adequate to support our long-term liquidity needs. However, we may elect to finance certain of our capital expenditure requirements through other sources of capital. We continue to follow our strategy to further strengthen our financial position by using available cash flow to fund operations. We intend to continue to consider acquisition opportunities at valuations we believe are reasonable based upon market conditions. However, we cannot accurately predict the timing, size and success of our acquisition efforts or our associated potential capital commitments. Furthermore, we cannot assure you that we will be able to acquire businesses on terms 47 -------------------------------------------------------------------------------- Table of Content s acceptable to us. We expect to fund future acquisitions, if any, through existing cash balances and cash flows from operations (as in our acquisition of EOT) and additional borrowings (as in our acquisition of Rofin). If required, we will consider the issuance of securities. The extent to which we will be willing or able to use our common stock to make acquisitions will depend on its market value at the time and the willingness of potential sellers to accept it as full or partial payment. OnApril 19, 2021 , we acquired EOT for approximately$29.3 million in cash.

OnOctober 29, 2021 , we entered into a10.0 million Euro letter of credit facility, rolled our existing letter of credit into that facility and deposited10.5 million Euros with Barclays as cash collateral to secure the payment obligations under such facility. We then terminated that facility onMarch 1, 2022 . No cash was restricted under this facility as ofApril 2, 2022 . Additional sources of cash available to us were international currency lines of credit and bank credit facilities totaling$13.8 million as ofApril 2, 2022 , of which$12.3 million was unused and available. These unsecured international credit facilities were used inEurope during the first six months of fiscal 2022. As ofApril 2, 2022 , we had utilized$1.5 million of the international credit facilities as guarantees inEurope . Our ratio of current assets to current liabilities increased to 3.3:1 atApril 2, 2022 compared to 3.1:1 atOctober 2, 2021 . The increase in our ratio was primarily due to lower other current liabilities, lower short-term borrowings and higher inventories partially offset by lower cash and cash-equivalents and higher income taxes payable.
