Customer and revenue · Customer concentration and key customer dependence
We have depended, and will continue to depend, upon a small number of customers for a significant percentage of our revenues. During fiscal years 2026, 2025 and 2024, we had four, two and two customers, respectively, that each contributed 10% or more of our revenues. Such customers together accounted for 57.4%, 45.8% and 48.5% of our revenues during the respective periods.
Market position and competition · Industry consolidation and market concentration
Consolidation in the markets we serve has resulted in a reduction in the number of potential customers for our services. For example, Nokia Corporation completed its acquisition of Infinera Corporation in February 2025; Lumentum Holdings Inc. completed its acquisition of NeoPhotonics Corporation in August 2022; Coherent Corp. completed its acquisition of Coherent, Inc. in July 2022; and Cisco Systems, Inc. completed its acquisition of Acacia Communications, Inc. in March 2021.
Customer and revenue · Revenue concentration in specific products or segments
Revenues from data center products represented 47.9% and 46.2% of our revenues for fiscal year 2026 and fiscal year 2025, respectively. Revenues from communications infrastructure products represented 33.3% and 30.7% of our revenues for fiscal year 2026 and fiscal year 2025, respectively.
Market position and competition · Market cyclicality and demand volatility
Our quarterly revenues, gross profit margins, and operating results have fluctuated significantly and may continue to fluctuate significantly in the future. For example, any of the risks described in this 'Risk Factors' section and, in particular, the following factors, could cause our revenues, gross profit margins, and operating results to fluctuate from quarter to quarter: the cyclicality of the optical communications, automotive, industrial lasers, medical, and sensors markets.
Market position and competition · Competitive pressure and market share loss
We face significant competition in our business. Our current and prospective customers tend to evaluate our capabilities against the merits of their internal manufacturing as well as the capabilities of other third-party manufacturers. Many of our customers and potential competitors have longer operating histories, greater name recognition, larger customer bases and significantly greater resources than we have.
Customer and revenue · Customer retention and subscription renewal
Cancellations, delays or reductions of customer orders and the relatively short-term nature of the commitments of our customers could harm our business, financial condition and operating results. We do not typically obtain firm purchase orders or commitments from our customers that extend beyond 13 weeks.
