Competition

The EMS industry is highly competitive and subject to rapid change. Furthermore, both large and small companies compete in the industry, and many have significantly greater financial resources, more extensive business experience and greater marketing and production capabilities than the Company. The significant competitive factors in this industry include price, quality, service, timeliness, reliability, the ability to source raw components, and manufacturing and technological capabilities. The Company believes it can compete on all of these factors.

Consolidation

As a result of consolidation and other transactions involving competitors and other companies in the Company’s markets, the Company occasionally reviews potential transactions relating to its business, products and technologies. Such transactions could include mergers, acquisitions, strategic alliances, joint ventures, licensing agreements, co-promotion agreements, financing arrangements or other types of transactions. In the future, the Company may choose to enter into these types of or other transactions at any time depending on available sources of financing, and such transactions could have a material impact on the Company’s business, financial condition or operations.

Governmental Regulations

The Company’s operations are subject to certain foreign government, U.S. federal, state and local regulatory requirements relating to, among others, environmental, waste management, consumer, labor and health and safety matters. Management believes that the Company’s business is operated in compliance with all such regulations, which include European regulations known as Restriction of Hazardous Substances (“RoHS”) and Registration, Evaluation, Authorization and Restriction of Chemicals (“REACH”). From time-to-time the Company's customers request REACH required information and certifications on the assemblies the Company manufactures for them. These requests require the Company to gather information from component suppliers to verify the presence and level of mass of any substances of very high concerns (“SVHCs”) greater than 0.1% in the assemblies the Company manufactures based on customer specifications. If any SVHCs are present at more than 0.1% of the mass of the item, the specific concentration and mass of the SVHC must be reported to proper authorities by the Company's customer.

Backlog

The Company relies on binding forecasted orders and purchase orders (firm orders) from its customers to estimate backlog. The Company’s backlog of firm orders as of April 30, 2024, and April 30, 2023, was approximately $289,900,000 and $387,350,000, respectively. The Company believes a significant portion of the backlog at April 30, 2024, will ship in fiscal year 2025. Because customers may cancel or reschedule deliveries, backlog may not be a meaningful indicator of future revenue. Variations in the magnitude and duration of contracts, forecasts and purchase orders received by the Company and delivery requirements generally may result in substantial fluctuations in backlog from period to period. The Company believes the

decrease in backlog is largely the result of customers shortening the forecasting period as market conditions and lead times for components have improved.

Human Capital Resources

The Company employed approximately 2,750 full-time employees of which approximately 490 were located in the U.S. as of April 30, 2024. There were approximately 240 engaged in engineering or engineering-related services, 2,090 in manufacturing and 420 in administrative functions, including supply chain, accounting, management and sales and marketing.

The Company makes a considerable effort to maintain a qualified and engaged work force. The Company makes a concerted effort to engage its employees and provide opportunities for growth and the Company believes that its employee relations are good. The Company considers the health and safety of its employees a key priority. The Company considers the health and safety of its employees a key priority, and even more during the COVID-19 pandemic.

ITEM 1A. RISK FACTORS

The following risk factors should be read carefully in connection with evaluating our business and the forward-looking information contained in this Annual Report on Form 10-K. Any of the following risks could materially adversely affect our business, operations, industry or financial position or our future financial performance. While the Company believes it has identified and discussed below the key risk factors affecting its business, there may be additional risks and uncertainties that are not presently known or that are not currently believed to be significant that may adversely affect its business, operations, industry, financial position and financial performance in the future.

Business and Operational Risks

Raw material price increases and supply shortages could adversely affect results.

The supply of raw materials to the Company and to its component parts suppliers could be interrupted for a variety of reasons, including availability and pricing. In particular, inflation, changes in trade policies, the imposition of duties and tariffs, potential retaliatory countermeasures, public health crises (such as the COVID-19 pandemic), and geopolitical conflicts (including involving Russia, Belarus, or Ukraine, which supply raw materials, such as neon, palladium and nickel, to the semiconductor industry) could adversely impact the price or availability of raw materials. Prices for raw materials necessary for production have fluctuated significantly in the past and the Company is currently experiencing upward pricing pressure on raw materials. Historically, it has been difficult to pass increased prices for components and raw materials through to our customers in the form of price increases. The Company may not be able to pass along increased raw material and components parts prices to its customers in the form of price increases or its ability to do so could be delayed. Significant price increases for components and raw materials could adversely affect the Company’s results of operations and operating margins. Consequently, its results of operations and financial condition may be adversely affected.

The Company experiences variable operating results.

The Company’s results of operations have varied and may continue to fluctuate significantly from period to period, including on a quarterly basis. Consequently, results of operations in any period should not be considered indicative of the results for any future period, and fluctuations in operating results may also result in fluctuations in the price of the Company’s common stock.

The Company’s quarterly and annual results may vary significantly depending on numerous factors, many of which are beyond the Company’s control. Some of these factors include:

- changes in availability and rising component costs

- changes in sales mix to customers

- volume of customer orders relative to capacity

- market demand and acceptance of our customers’ products

- price erosion within the EMS marketplace

- capital equipment requirements needed to remain technologically competitive

- volatility in the U.S. and international economic and financial markets

The volume and timing of sales to the Company’s customers may vary due to:

- component availability

- variation in demand for the Company’s customers’ products

- customers’ attempts to manage their inventory

- design changes

- acquisitions of or consolidation among customers

Most of the Company’s customers’ production schedules are volatile, which makes it difficult to schedule production and achieve maximum efficiency at the Company’s manufacturing facilities and manage inventory levels.

The Company’s inability to forecast the level of customer orders with certainty can make it difficult to schedule production and maximize utilization of manufacturing capacity and manage inventory levels. The Company could be required to increase or decrease staffing and more closely manage other expenses in order to meet the anticipated demand of its customers. Orders from the Company’s customers could be cancelled or delivery schedules could be deferred or accelerated as a result of changes in our customers’ demand, which can put added stress on resources. Sudden decreases in production can lead to excess inventory on hand which may or may not be reimbursed by our customers even when under contract. These and other factors could harm our ability to achieve anticipated levels of profitability and thereby adversely affecting the Company’s results of operations in any given period.

The Company’s inventory levels have been adversely impacted by the global supply chain crisis, with an unprecedented impact on working capital requirements.

The impact of component shortages on sales of finished goods and the resulting increase in inventory levels in prior fiscal years had been unprecedented although inventory levels have decreased significantly during fiscal year 2024. The supply chain uncertainty has significantly lessened during the fiscal year, however there are still certain components that are difficult to obtain on a timely basis. The continued impact of increased inventory levels on working capital requirements materially increases our operating costs and if it continues unabated, could materially and adversely affect our business and results of operations.

If our manufacturing processes and services do not comply with applicable statutory and regulatory requirements, or if we manufacture products containing design or manufacturing defects, demand for our services may decline and we may be subject to liability claims.
