Fiscal period ending 2026-07-03 versus 2025-06-27view filing on EDGAR →

Four distinct risk dimensions worsened this period, with no offsetting easing. Geopolitical exposure expanded materially — now encompassing Iran conflict, sanctions, supply chain reconfiguration, and state-sponsored cyber threats — while Pillar Two tax headwinds moved from prospective to realized, confirming an earnings drag already underway. A newly quantified 14% single-customer revenue concentration and a freshly introduced cybersecurity risk factor round out a broad, if not existential, deterioration in the risk profile.

Company-specific changes

Revised

Added specific quantification: one customer represents 14% of revenue. This concrete disclosure of customer concentration escalates the risk from general to measurable, making the impact more tangible to investors.

A limited number of our key customers account for a significant portion of our revenue, and we have been, and may in the future be, adversely affected by reduced, delayed, loss of or canceled…

Geopolitical macro uncertainty Revised

Added Iran conflict, sanctions/tariffs/trade restrictions, supply chain reconfiguration costs, state-sponsored cybersecurity risks, and geographic concentration vulnerability—substantive escalation of geopolitical and supply chain risk.

Tariff exposure has sharpened from general uncertainty to concrete supply chain disruption and retaliation risk, while Pillar Two global minimum tax is now a quantified near-term cost burden beginning FY2026 in Singapore and Thailand. Together, these two changes represent a meaningful step-up in both operational and tax risk with limited mitigation offsets disclosed.

Material year-over-year changes to this company's Risk Factors (Item 1A), found by comparing each annual report to the prior year, judged for materiality, and classified as company-specific or common-mode against the cross-company catalog. Common-mode changes are the macro themes many companies disclose in common; they are collapsed above. A filing marked unchanged had no material change from the prior year; its summary describes the company's standing risks, which remain in force. Fiscal periods are the reporting period ends.
