### Risk Assessment

- **[METRIC] Communications Equipment Balance Sheet Resilience** (NEGATIVE, Risk: HIGH): The risk is easing as the total principal amount of convertible notes has decreased to $2,514.7 million following the full repayment of the 2024 Notes in March 2024. Additionally, management made irrevocable elections to settle the principal of the 2028 and 2029 notes in cash, reducing potential equity dilution. (2 easing, 3 stable, 1 high-severity)
  > Since the closing price of our stock was at least 130% of the applicable conversion price for each series of Notes for 20 of the last 30 trading days of our second and third quarters of fiscal year 2026, all of our Notes remain convertible at the option of the holders during the fourth quarter of fi
- **[METRIC] Communications Equipment Margin Profile** (POSITIVE, Risk: LOW): The risk is easing as the company has undertaken significant restructuring to consolidate sites and reduce excess capacity. Gross margins improved to 28.0% in FY25 from 18.5% in FY24 as inventory levels normalized and demand for AI products increased. (4 easing)
  > Our revenue fluctuated in response to these changes in demand and our margins were adversely impacted as we were not able to fully recover costs, such as underutilized manufacturing capacity.
- **[METRIC] Communications Equipment Revenue Growth** (NEUTRAL): The risk is stable but active; the company recorded a decrease in net foreign exchange gains due to the strengthening U.S. Dollar against the Yen, which impacts the valuation of the Japan term loans. (1 stable)
  > primarily driven by a decrease in net foreign exchange gains of $6.5 million as the U.S. dollar strengthened against the Japanese Yen, which is the underlying currency for our term loans.
- **[PRINCIPLE] Communications Equipment Regulatory Position** (NEUTRAL, Risk: MODERATE): The risk is stable as the cessation of business with Huawei is now fully reflected in the financials. The company stopped all shipments to Huawei in early 2024, and the regulatory environment remains restrictive with no signs of easing. (3 stable)
  > In August 2024, we received inquiries from the Bureau of Industry and Security of the U.S. Department of Commerce (“BIS”) and Department of Justice (“DOJ”) following our voluntary disclosure to BIS... We are unable to predict the likely outcome of these matters.
- **[PRINCIPLE] Communications Equipment Revenue Quality** (NEGATIVE, Risk: HIGH): Customer concentration remains high but has slightly diversified. The top two customers now account for 31.4% of total revenue (16.0% and 15.4%), down from the previously reported 38%. However, the company still relies on a limited pool for the majority of its sales. (1 easing, 3 intensifying, 1 high-severity)
  > During the three months ended March 28, 2026, two customers individually accounted for 26% and 12% of our total revenue, respectively.
- **[PRINCIPLE] Communications Equipment Unit Economics** (NEUTRAL): The risk is stable but remains a concern as the company entered into a new Mizuho Term Loan in September 2024, maintaining its exposure to Yen-denominated debt. Foreign exchange losses were $4.2 million in FY25. (1 stable)
  > On September 20, 2024, the Company entered into a term loan agreement (the “Mizuho Term Loan”)... provides for borrowings of 4.5 billion JPY... The SMBC Term Loan and the Mizuho Term Loan are collectively referred to as Japan Term Loans.
- **[TREND] Communications Equipment Market Structure** (NEUTRAL, Risk: MODERATE): Lumentum is facing intense pricing pressure and 'commoditization' (where products become so common that price is the only differentiator), especially from competitors in Asia. This forces the company to constantly lower prices, which can shrink profit margins. [COMPETITIVE]
  > The market for optical communications products in particular has matured over time and these products have increasingly become subject to commoditization. Both legacy competitors as well as new entrants, predominantly Asia-based competitors, have intensified market competition in recent years leadin
- **[TREND] Communications Equipment Policy and Regulation** (NEGATIVE, Risk: HIGH): The risk is intensifying as the company received formal administrative subpoenas from both the BIS and DOJ in August 2024, indicating the investigations are active and progressing. (2 intensifying, 1 stable, 1 high-severity)
  > Under the current regulatory policy and rules, our business with Huawei is now completely restricted... This cessation of all business activities with Huawei has resulted in our inability to earn revenue from Huawei and negatively impacted our financial condition
- **[TREND] Communications Equipment Supply Chain Reconfiguration** (POSITIVE, Risk: MODERATE): Concentration with the primary contract manufacturer has intensified. Contract Manufacturer A now accounts for 25.1% of total net inventory purchases, up from the previously reported 19%. (1 intensifying, 1 stable, 2 easing)
  > During the three and nine months ended March 28, 2026, our net inventory purchases from a single contract manufacturer that represented 10% or greater of our total net inventory purchases were concentrated with one contract manufacturer, who accounted for 19% of the total net inventory purchases

### Scenario Analysis

- The surge in hyperscaler capex for AI infrastructure has triggered a massive demand for Lumentum’s 200G optical transceivers and circuit switches, nearly doubling its revenue year-over-year. This first-order demand shift forces a second-order expansion of manufacturing capacity, which Lumentum is funding through strategic equity partnerships with industry leaders like NVIDIA. Ultimately, this positions Lumentum as a third-order 'compute supply moat' provider, where its proprietary optical technology becomes a critical bottleneck for any firm attempting to scale large-scale AI training clusters. (POSITIVE)
  > In August 2024, we received an administrative subpoena from BIS requesting the production of records in connection with our business with Huawei. We also received a related subpoena from the U.S. Department of Justice (“DOJ”) ... Any failure or alleged failure to comply with export controls laws and
- The shift in the US rate cycle first impacts Lumentum through equity valuation shifts, where rapid stock appreciation triggered convertible debt conversion rights, creating a technical liquidity risk. However, this is superseded by the second-order effect of falling capital costs, which accelerates AI/ML infrastructure spending by major cloud providers, Lumentum's primary customers. Ultimately, this leads to a third-order structural shift where Lumentum emerges as a leader in the long-duration growth rotation, as its $2B NVIDIA partnership provides a fundamental growth engine that outweighs macro-driven interest expense concerns. (POSITIVE)
  > Since the closing price of our stock was at least 130% of the applicable conversion price for each series of Notes... all of our Notes remain convertible at the option of the holders... The outstanding Notes are recorded as short-term debt, which is presented as current liabilities
- The imposition of tariffs and export controls has permanently severed Lumentum's access to high-volume Chinese revenue pools like Huawei, while simultaneously inflating the cost of critical mineral inputs like gallium. This creates a second-order demand vacuum in 5G infrastructure as Chinese customers lose access to the broader semiconductor ecosystem, forcing Lumentum to hold more safety stock and manage a less predictable backlog. Ultimately, the company is undergoing a painful structural migration where it must trade high-margin international sales for higher-cost domestic production in facilities like Greensboro to maintain strategic relevance in the US AI buildout. (NEGATIVE)
  > The Company is actively monitoring and assessing the ongoing global trade environment, particularly with respect to recent changes in trade restrictions and tariff regulations... import tariffs and other trade restrictions implemented by the U.S. and other countries, as currently in effect and/or pr
