Overview

We are a leader in the design, engineering, and manufacturing of critical fluid delivery subsystems and components for semiconductor capital equipment. Our product offerings include gas and chemical delivery systems and subsystems, collectively known as fluid delivery systems and subsystems, which are key elements of the process tools used in the manufacturing of semiconductor devices. Our gas delivery subsystems deliver, monitor, and control precise quantities of the specialized gases used in semiconductor manufacturing processes such as etch and deposition. Our chemical delivery systems and subsystems precisely blend and dispense the reactive liquid chemistries used in semiconductor manufacturing processes such as chemical-mechanical planarization, electroplating, and cleaning. We also provide precision-machined components, weldments, e­beam and laser-welded components, precision vacuum and hydrogen brazing and surface treatment technologies, and other proprietary products. This vertically integrated portion of our business is primarily focused on metal and plastic parts that are used in gas and chemical systems, respectively.

Fluid delivery subsystems ensure accurate measurement and uniform delivery of specialty gases and chemicals at critical steps in the semiconductor manufacturing processes. Any malfunction or material degradation in fluid delivery reduces yields and increases the likelihood of manufacturing defects in these processes. Most OEMs outsource all or a portion of the design, engineering, and manufacturing of their gas delivery subsystems to a few specialized suppliers, including us. Additionally, many OEMs are outsourcing the design, engineering, and manufacturing of their chemical delivery subsystems due to the increased fluid expertise required to manufacture these subsystems. Outsourcing these subsystems has allowed OEMs to leverage the suppliers' highly specialized engineering, design, and production skills while focusing their internal resources on their own value-added processes. We believe that this outsourcing trend has enabled OEMs to reduce their costs and development time, as well as provide growth opportunities for specialized subsystems suppliers like us.

We have a global footprint with production facilities in California, Minnesota, Oregon, Texas, Singapore, Malaysia, the United Kingdom, Korea, and Mexico.

COVID-19 Pandemic and Market Conditions Update

The COVID­19 pandemic and associated macroeconomic impacts, including supply chain disruptions, tightened labor markets, and overall increased inflation have created, and are expected to continue to create significant volatility, uncertainty, and turmoil in our industry. While our facilities are currently not subject to any site-wide government shutdowns, and restrictions have eased around social, business, travel, and governmental activities, we have experienced increases in direct costs and inefficiencies within our factories associated with logistics, employee labor, and certain component shortages. These factors have resulted in, and may continue to result in, lower revenues and operating margins. The extent and duration of these impacts cannot be specifically quantified given the dynamic nature and breadth of the pandemic's impact on our operations and that of our customers and suppliers.

Comparison of the three months ended April 1, 2022 and March 26, 2021

Net Sales



               Three Months Ended              Change
            April 1,      March 26,
              2022           2021         Amount        %
                         (dollars in thousands)
Net sales   $ 293,146     $  264,566     $ 28,580       10.8 %

The increase in net sales from the first quarter of 2021 to the first quarter of 2022 was primarily due to strong demand from our customers as a result of continued growth in the global wafer fabrication equipment market as well as incremental revenues from our acquisition of IMG Companies, LLC ("IMG") in November 2021, partially offset by production constraints as a result of challenges in our supply chain.

Net sales to U.S. customers increased by $3.3 million in the first quarter of 2022 to $142.5 million. On a relative basis, net sales to U.S. customers as a percent of total net sales decreased from 52.6% in the first quarter of 2021 to 48.6% in the first quarter of 2022.

Net sales to international customers increased by $25.2 million in the first quarter of 2022 to $150.7 million. On a relative basis, net sales to international customers as a percent of total net sales increased from 47.4% in the first quarter of 2021 to 51.4% in the first quarter of 2022.

Cost of Sales, Gross Profit, and Gross Margin



                   Three Months Ended                Change
                April 1,      March 26,

                               (dollars in thousands)
Cost of sales   $ 249,214     $  225,054     $ 24,160           10.7 %
Gross profit    $  43,932     $   39,512     $  4,420           11.2 %
Gross margin         15.0 %         14.9 %                  + 10 bps

The increase in the gross amounts of cost of sales and gross profit from the first quarter of 2021 to the first quarter of 2022 were primarily due to the factors mentioned in the commentary above under the heading, "Net Sales."

The increase in our gross margin from the first quarter of 2021 to the first quarter of 2022 was primarily due to accretive margins from our recent acquisition of IMG in November 2021, partially offset by increased materials, logistics, and labor costs, as we invest in our capacity to service present levels of strong customer demand in future quarters, and the impacts of component and material shortages, due to supply chain challenges, reducing factory utilization.

Research and development   $    4,851      $     3,515     $ 1,336       38.0 %

The increase in research and development expenses from the first quarter of 2021 to the first quarter of 2022 was primarily due to increased employee-related expense, as we expand our engineering team to design and engineer next generation, high performance solutions for our customers.

Selling, General, and Administrative



                                           Three Months Ended               Change
                                        April 1,       March 26,
                                          2022           2021         Amount        %
                                                    (dollars in thousands)

Selling, general, and administrative $ 23,267 $ 14,349 $ 8,918 62.2 %

The increase in selling, general, and administrative expense from the first quarter of 2021 to the first quarter of 2022 was primarily due to a non-recurring loss accrual of $3.1 million related to a probable settlement of an employment-related legal matter; $3.0 million in incremental selling, general, and administrative expense from our acquisition of IMG in November 2021, $1.7 million in increased employee-related costs, inclusive of increased share-based compensation expense; $0.8 million in increased professional, consulting, and audit fees; and $0.3 million in transaction-related fees costs associated with our acquisition of IMG.

Amortization of Intangible Assets

                                                   (dollars in thousands)

Amortization of intangibles assets $ 5,349 $ 3,391 $ 1,958 57.7 %

The increase in amortization expense from the first quarter of 2021 to the first quarter of 2022 was primarily due to incremental amortization expense from intangible assets acquired in connection with our acquisition of IMG in November 2021, partially offset by reduced amortization expense due to an older customer relationship asset reaching full amortization in the fourth quarter of 2021.



Interest Expense, Net

                            Three Months Ended                Change
                         April 1,        March 26,
                           2022            2021         Amount         %
                                      (dollars in thousands)
Interest expense, net   $    1,532      $     1,919     $  (387 )     -20.2 %

The decrease in interest expense, net from the first quarter of 2021 to the first quarter of 2022 was primarily due to a 147­basis point decrease in our weighted average interest rate, from 3.30 % to 1.83%, respectively, and a decrease in debt issuance cost amortization expense, partially offset by a $105.0 million increase in average debt outstanding during the first quarter of 2022 compared to the first quarter of 2021 as a result of drawing $130.0 million on our revolving credit facility in November 2021 to partially fund our acquisition of IMG. The decrease in our weighted average interest rate from the first quarter of 2021 to the first quarter of 2022 was primarily due to a decrease in our leverage ratio, which reduces the applicable margin component of our all-in borrowing rate, as well as lower overall applicable margins under our October 2021 amended and restated credit agreement.

Other expense, net   $       84       $      185     $  (101 )     -54.6 %

The change in other expense, net from the first quarter of 2021 to the first quarter of 2022 was primarily due to currency exchange rate fluctuations during the quarter as a result of transactions denominated in the local currencies of our foreign operations.



Income Tax Expense

                         Three Months Ended                Change
                     April 1,         March 26,
                       2022             2021         Amount         %
                                   (dollars in thousands)
Income tax expense   $     810       $     1,515     $  (705 )     -46.5 %

The decrease in income tax expense from the first quarter of 2021 to the first quarter of 2022 was primarily due to decreased taxable income in the U.S. in the first quarter of 2022 and reduced benefits from share-based compensation activity during the quarter.

Non­GAAP Financial Results

Management uses non-GAAP metrics to evaluate our operating and financial results. We believe the presentation of non-GAAP results is useful to investors for analyzing business trends and comparing performance to prior periods, along with enhancing investors' ability to view our results from management's perspective. Non-GAAP gross margin is defined as non-GAAP gross profit divided by net sales. Non-GAAP gross profit and non-GAAP net income are defined as: gross profit or net income excluding, as applicable, (1) amortization of intangible assets, share-based compensation expense, and non-recurring expenses, including settlement losses, facility shutdown costs, and acquisition-related costs and charges, to the extent they are present in gross profit or net income; and (2) the tax impacts associated with our non-GAAP adjustments, as well as non-recurring discrete tax items. Non-GAAP diluted earnings per share ("EPS") is defined as non-GAAP net income divided by weighted average diluted ordinary shares outstanding during the period.

Non-GAAP results have limitations as an analytical tool, and you should not consider them in isolation or as a substitute for our results reported under GAAP. Other companies may calculate non-GAAP results differently or may use other measures to evaluate their performance, both of which could reduce the usefulness of our non-GAAP results as a tool for comparison.

Because of these limitations, you should consider non-GAAP results alongside other financial performance measures and results presented in accordance with GAAP. In addition, in evaluating non-GAAP results, you should be aware that in the future we will incur expenses such as those that are the subject of adjustments in deriving non-GAAP results and you should not infer from our presentation of non-GAAP results that our future results will not be affected by these expenses or any unusual or non-recurring items.

The following table presents our unaudited non­GAAP gross profit and non-GAAP gross margin and a reconciliation from gross profit, the most comparable GAAP measure, for the periods indicated:

  (2)  As part of the purchase price allocations of our acquisitions of IMG in
       November 2021 and a precision machining operation in Mexico in
       December 2020, we recorded acquired-inventories at fair value, resulting in
       a fair value step-up of $3.9 million and $0.2 million, respectively. These
       amounts were subsequently released to cost of sales as acquired-inventories
       were sold.


  (3)  Included in this amount for the first quarter of 2021 is primarily a
       non-recurring settlement charge.

  (2)  During the first quarter of 2022, we recorded a non-recurring loss accrual
       of $3.1 million relating to an expected settlement of an employment-related
       legal matter. We expect the settlement to be finalized and paid within the
       next 12 months.


  (3)  As part of the purchase price allocations of our acquisitions of IMG in
       November 2021 and a precision machining operation in Mexico in
       December 2020, we recorded acquired-inventories at fair value, resulting in

  (4)  Included in this amount are incremental transaction-related costs incurred
       in connection with our acquisition of IMG in November 2021.


  (5)  Included in this amount for the first quarter of 2021 are primarily
       (i) non-capitalized costs incurred in connection with our implementation of
       a new ERP system and a Sarbanes-Oxley compliance program and (ii) a
       non-recurring settlement charge.


  (6)  Adjusts U.S. GAAP income tax expense (benefit) for impact of our non-GAAP
       adjustments, as defined, including the impacts of excluding share-based
       compensation, amortization of intangible assets, and other non-recurring
       expenses. This adjustment also excludes the impact of non-recurring
       discrete tax items.

Liquidity and Capital Resources

The following section discusses our liquidity and capital resources, including our primary sources of liquidity and our material cash requirements. Our cash and cash equivalents are maintained in highly liquid and accessible accounts with no significant restrictions.

Material Cash Requirements

Our primary liquidity requirements arise from: (i) working capital requirements, including procurement of raw materials inventory for use in our factories and employee-related costs, (ii) business acquisitions, (iii) interest and principal payments under our credit facilities, (iv) research and development investments and capital expenditures, and (v) payment of income taxes. We have no significant long-term purchase commitments related to procuring raw materials inventory. Our ability to fund these requirements will depend, in part, on our future cash flows, which are determined by our future operating performance and are therefore subject to prevailing global macroeconomic conditions and financial, business, and other factors, some of which are beyond our control.

We believe that our cash and cash equivalents, the amounts available under our credit facilities, and our operating cash flow will be sufficient to fund our business and our current obligations for at least the next 12 months and beyond.

Sources and Conditions of Liquidity

Our ongoing sources of liquidity to fund our material cash requirements are primarily derived from: (i) sales to our customers and the related changes in our net operating assets and liabilities and (ii) proceeds from our credit facilities and equity offerings, when applicable.
