What could break the thesis?
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”
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.”
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 fiscal year 2026. The outstanding Notes are recorded as short-term debt, which is presented as current liabilities”
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 leading to pricing pressure.”
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.”
