What Changed
Risk factors · Nov 14, 2024 → Nov 20, 202571 added · 74 removed between the two most recent 10-Ks. The risks a company starts — or stops — disclosing are often the story.
Newly disclosed
- For example, in January 2025, a magnitude 6.4 earthquake struck Tainan, Taiwan, resulting in a temporary suspension of business and services.
- While the BIS rescinded its "Framework for AI Diffusion" in May 2025, there is a possibility of a replacement rule or other similar rules being introduced in the future.
- For example, the imposition of tariffs and export controls have indirectly led to an increase in the cost of our products, which if improperly managed, could in turn materially and adversely affect our ability to sell our products in foreign markets.
- This website reference is provided for convenience only and the content on the referenced website is expressly not incorporated by reference into this Annual Report on Form 10-K. 13 Table of Contents Human Capital Our Employees Our talented employees are critical to our ability to achieve the Company’s vision to be the leading technology and service provider of innovative interconnect solutions enabling a smart future.
- Our HR function also includes centers of excellence in Talent Management, Talent Acquisition, HR Shared Services, and Global Compensation and Benefits, ensuring best practices in these important areas. 14 Table of Contents Employee Development We believe in investing in our employees’ professional growth by encouraging them to continually develop their functional and leadership skills and to gain different experiences across the Company as they progress along their career paths and grow within our organization.
- Dividends On each of August 29, 2025, June 5, 2025, March 6, 2025 and November 13, 2024, the Board of Directors declared a quarterly dividend of $0.205 per share of common stock, resulting in an aggregate dividend of $0.82 per share of common stock for the fiscal year ended October 4, 2025.
- Because of the volatility of customer demand, possibility of customer changes in delivery schedules or cancellations and potential delays in product shipments, our backlog as of any particular date may not be indicative of net revenue for any succeeding period. 11 Table of Contents The following table reflects our backlog as of October 4, 2025 and September 28, 2024: As of (in thousands) October 4, 2025 September 28, 2024 Backlog $ 245,280 $ 148,585 Manufacturing We believe excellence in manufacturing can create a competitive advantage, both by producing at lower costs and by providing superior responsiveness to changes in customer demand.
- In fiscal 2024, we performed an independent, limited external assurance of our direct (Scope 1) and purchased energy indirect (Scope 2) greenhouse gas emissions data, as well as selected sustainability performance data on paper usage, water consumption, and waste generated and disposed, under the operational control boundary of seven of our global operational sites.
- In September 2025, the BIS promulgated the new “ Affiliates Rule ”, which applied restrictions on exports (and reexports and transfers) to any foreign entity that is at least 50% owned, individually or in the aggregate, by one or more entities named on the Entity List, the Military End-User List, or those designated with certain identifiers on the Specially Designated Nationals List of the Office of Foreign Assets Control.
- Sales to our ten largest customers comprised 54.8% and 53.6% of our net revenue for fiscal 2025 and fiscal 2024, respectively. 22 Table of Contents We expect that a small number of customers will continue to account for a high percentage of our net revenue for the foreseeable future.
- The cessation of the EA equipment business is subject to a consultation process with the applicable works council and union representatives, which the Company initiated in the third fiscal quarter of 2025 and, as of October 4, 2025, had substantially completed.
- In fiscal 2024, we performed an independent, limited external assurance of our direct (Scope 1) and purchased energy indirect (Scope 2) greenhouse gas emission data, as well as selected sustainability performance data that included paper usage, water consumption, and waste generated and disposed, under the operational control boundary of seven of our global operational sites, and published such limited external assurance in our sustainability report.
No longer disclosed
- For example, in March 2022, the SEC published a proposed rule that would require companies to provide significantly expanded climate-related disclosures in their Form 10-K, which may require us to incur significant additional costs to comply and impose increased oversight obligations on our management and Board of Directors.
- For example, in April 2024, a magnitude 7.4 earthquake struck Taiwan, resulting in significant injuries and death, leading to a temporary suspension of business and services.
- For example, we are currently investigating a 23 Table of Contents potential unlawful reverse engineering incident and, where necessary, plan to pursue appropriate legal action against parties that may be involved in such unlawful reverse engineering.
- A protectionist trade environment in either the U.S. or those foreign countries in which we do business, such as a change in the current tariff structures, export compliance or other trade policies, may materially and adversely affect our ability to sell our products in foreign markets.
- As of September 28, 2024, our remaining stock repurchase authorization under the Program was approximately $30.3 million. 4 Table of Contents Dividends On August 26, 2024, May 16, 2024, March 14, 2024 and November 15, 2023, the Board of Directors declared a quarterly dividend of $0.20 per share of common stock, resulting in an aggregate dividend of $0.80 per share of common stock for the fiscal year ended September 28, 2024.
- The following table reflects our backlog as of September 28, 2024 and September 30, 2023: As of (in thousands) September 28, 2024 September 30, 2023 Backlog $ 148,585 $ 423,824 Manufacturing We believe excellence in manufacturing can create a competitive advantage, both by producing at lower costs and by providing superior responsiveness to changes in customer demand.
- In fiscal 2022, we embedded our four corporate social responsibility pillars into a wider ESG framework now covering the full spectrum of ESG-related efforts and initiatives, and further integrated these ESG-related considerations, efforts and initiatives into many of our business and operational practices.
- In fiscal 2023, we performed an independent, limited external assurance of our direct (Scope 1) and purchased energy indirect (Scope 2) greenhouse gas emissions data under the operational control boundary of eight of our global operational sites.
- In particular, trade tensions between the U.S. and China have been escalating since 2018, with U.S. tariffs on Chinese goods and retaliatory Chinese tariffs on U.S. goods, and there remains significant uncertainty about the future relationship between the U.S. and China.
- In connection with the cancellation of a project with one of its customers (previously referred to as Project W) (the "Project"), on March 11, 2024, the Company committed to a plan to cease operational activities and commence wind down activities concerning various aspects of the Project.
- In fiscal 2023, we performed an independent, limited external assurance of our direct (Scope 1) and purchased energy indirect (Scope 2) greenhouse gas emission data under the operational control boundary of eight of our global operational sites, and published such limited external assurance in our sustainability report.
