Before investing in our securities, you should consider carefully the information contained in this report, including the information in this “Risk Factors” section.
Risks Related to Financial Performance and Strategy Our revenue, gross margin, and operating results can be adversely impacted by a number of factors that would cause our results to fluctuate.
Our results of operations are subject to significant, and often difficult to predict, quarterly fluctuations due to a variety of factors.
A portion of our quarterly revenue is generated from customer orders received during that same quarter (which we refer to as “book to revenue”) and therefore may be less certain.
Additionally, our customer contracts generally do not include minimum or guaranteed purchases and may allow customers to modify or cancel purchase orders.
We must regularly compete for business with existing customers and there is no assurance that we will maintain our incumbency or revenue level with any particular customer in future periods.
Our results can be materially adversely affected by factors set forth in this “Risk Factors” section including: • order timing and volume, including book to revenue and backlog levels; • changes in spending or deployment plans by customers; • the level of competition we face and the impact of unfavorable transactions or commercial terms; • customer, product and geographic mix; • supply chain performance and costs; • the financial stability of our customers; and • consolidation activity involving us, our customers, suppliers, and competitors.
As a result, our historical financial results may not be indicative of future performance.
Quarterly fluctuations in our revenue, gross margin, and results of operations could cause us to fail to meet our guidance or the expectations of financial analysts or investors, which may cause volatility or decreases in our stock price.
Our revenue is concentrated among a small number of customers and reductions in their spending could materially adversely impact our results of operations.
A significant portion of our revenue is concentrated among a small number of customers.
For example, in fiscal 2025, our five largest customers contributed approximately 50% of our revenue, a cloud provider customer accounted for approximately 18% of our revenue, and a service provider accounted for approximately 11% of our revenue.
Consequently, our results of operations could be materially adversely impacted by the loss of or a significant reduction in spending of a large customer.
Moreover, our revenue is concentrated within the cloud provider and service provider customer segments.
Adverse economic, business or regulatory dynamics within these industries or market segments affecting spending levels could materially adversely impact our results of operations.
Our growth is dependent on executing our strategy and expanding our addressable market, and we may not be successful.
Our growth depends on the successful execution of our business strategy and our ability to grow our addressable market, or to expand into new markets, technologies, or customer segments.
A key part of this strategy is to leverage our optical technology leadership and expand our addressable market into complementary and adjacent markets by investing in new technologies, including for applications inside and around the data center, and specifically for AI-driven use cases.
Many of these markets are nascent or dynamic, and it is difficult to predict trends of these markets, including any potential growth.
Moreover, we have a more limited history in commercializing and selling solutions into these markets.
This expansion strategy may require a significant investment of capital and human resources, may disrupt our operations, and could impose substantial demands on management time.
If the markets relating to these solutions do not develop as we anticipate, or if we are unable to commercialize, increase market awareness of, or gain adoption of our solutions within those markets, our business, financial performance, and long-term growth prospects could be adversely affected.
We operate in an intense and evolving competitive landscape and the level of competitive pressure we face may adversely impact our results of operations.
We operate in a highly competitive environment, where we and our competitors aggressively seek to capture market share and displace incumbent vendors.
Many of these competitors have substantially greater resources, broader product offerings and more established customer relationships than we have.
Because of their scale and resources, they may be perceived to be a better fit for the procurement or network strategies of larger network operators.
We also face competition from certain smaller companies for specific products, applications, customer segments, or geographic markets that may be more attractive to customers in a particular opportunity.
Generally, competition in our industry is based on various factors, including: • price and total cost of ownership; • product features and functionality; • incumbency and strength of existing business relationships; • technology roadmap; • financial stability and investment capacity; • ability to address preferred customer consumption models; • delivery lead-times; and • services and support capabilities.
Additionally, as we address evolving customer consumption models or expand into adjacent market segments, we expect to compete with a broader range of suppliers, including existing business partners in our supply chain.
Increases in the intensity of competition we face may adversely impact our business and results of operations.
Acquisitions and other strategic transactions could disrupt our operations and expose us to increased costs and unexpected liabilities.
We may pursue strategic transactions, including mergers, acquisitions, investments and other strategic partnerships, to advance our business strategy.
These transactions inherently involve significant risks and uncertainties, including: • failure to achieve the intended benefits or anticipated return on investment, including operational synergies; • significant use of cash, assumption of debt, or dilution of stockholders; • exposure to unexpected costs or liabilities; • challenges integrating technology, operations and personnel, and loss of key employees; • disruption of relationships with customers, suppliers, or other business partners; • diversion of management attention; • challenges obtaining required regulatory or third-party approvals; and • adverse tax, internal control or financial reporting impacts.
If we are unable to successfully execute acquisitions and other strategic transactions our business, results of operations, and financial condition could be negatively impacted.
Risks Related to Technology Development and Intellectual Property Misaligned or delayed technology investments may adversely impact our return on innovation, impair our strategy and weaken our competitive position.
The success of our business depends on our ability to develop and deliver products that align with customer needs and demands, technological advancements, and market trends.
We continually invest in research and development to enhance our solutions and to develop new technologies.
There is often a lengthy period between commencing development and bringing these solutions to market.
Accordingly, there is no guarantee of market acceptance, and some of our development decisions will be unprofitable.
There is also a possibility that we may miss a market opportunity because we failed to invest or invested too late.

In addition to the other information contained in this annual report, you should consider the following risk factors before investing in our securities.
Risks Related to Our Business and Industry Our revenue, gross margin, and operating results can fluctuate significantly from quarter to quarter and, if we are not able to secure order growth, our revenue may not reach the levels we anticipate.
Our revenue, gross margin, and results of operations can fluctuate significantly from quarter to quarter.
Our budgeted expense levels are based on our intent to invest to maintain or increase our technology advantage, our visibility into customer spending plans, and our projections of future revenue and gross margin.
Visibility into customer spending levels can be uncertain, spending patterns are subject to change, and reductions in our expense levels can take significant time to implement.
Historically, a significant portion of our quarterly revenue was generated from customer orders received during that same quarter (which we refer to as “book to revenue”) and was therefore less predictable and subject to fluctuation due to a quarterly shortfall in orders from expectations.
During fiscal 2022, however, we generated a significant backlog of customer orders as a result of supply chain constraints and, during fiscal 2023, our revenue grew as we consumed a significant portion of this backlog.
Customer order volumes began to moderate in the fourth quarter of fiscal 2022, and we experienced order levels below revenue during fiscal 2023 and the first half of fiscal 2024 and, as a result, our backlog decreased.
We expect our backlog to continue to reduce in fiscal 2025.
As that happens, we expect our reliance upon securing quarterly book to revenue orders to grow and those orders to represent a more typical composition of our quarterly revenue over time.
Our future revenue growth will depend, in part, on securing increased orders, particularly book to revenue orders.
Within these dynamics, our results for a particular period can be difficult to predict and a range of factors, including those set forth below, can materially adversely affect quarterly revenue, gross margin, and operating results: • changes in spending levels or network deployment plans by customers, particularly with respect to our service provider and cloud provider customers; • order timing and volume, including book to revenue orders; • the timing of revenue recognition on sales, particularly relating to large orders; • availability of components and manufacturing capacity; • shipment and delivery timing, including any deferral of delivery; • backlog levels; • the level of competition and pricing pressure in our industry; • the pace and impact of price erosion that we regularly encounter in our markets; • the impact of commercial concessions or unfavorable commercial terms required to maintain incumbency or secure new opportunities with key customers; • the mix of revenue by product segment, geography, and customer in any particular quarter; • our level of success in achieving targeted cost reductions and improved efficiencies in our supply chain; • our incurrence of start-up costs, including lower margin phases of projects required to support initial deployments, to gain new customers, or to enter new markets; • our level of success in accessing new markets and obtaining new customers; • long- and short-term changing behaviors or customer needs that impact demand for our products and services, or the products and services of our customers; • technology-based price compression and our introduction of new platforms with improved price for performance; • changing market, economic, and political conditions, including the impact of tariffs and other trade restrictions or efforts to withdraw from or materially modify international trade agreements; • factors beyond our control such as natural disasters, climate change, acts of war or terrorism, and public health emergencies, such as epidemics and pandemics like the COVID-19 pandemic; • the financial stability of our customers and suppliers; • consolidation activity among our customers, suppliers, and competitors; • installation service availability and readiness of customer sites; • adverse impact of foreign exchange; and • any potential seasonal effects in our business.
As a result of these factors and other conditions affecting our business and operating results, we believe that quarterly comparisons of our operating results are not necessarily a good indication of future performance.
Quarterly fluctuations from the above and other factors may cause our revenue, gross margin, and results of operations to underperform in relation to our guidance, long-term financial targets or the expectations of financial analysts or investors, which may cause volatility or decreases in our stock price.
A small number of customers account for a significant portion of our revenue.
The loss of one or more of these customers, or a significant reduction in their spending, could have a material adverse effect on our business and results of operations.
A significant portion of our revenue is concentrated among a small number of communications service provider and cloud provider customers.
For example, our ten largest customers contributed 57.9% of our revenue for fiscal 2024 and 53.7% of our revenue for fiscal 2023.
A cloud provider customer accounted for approximately 13.3% of our total revenue for fiscal 2024 and 12.8% of our total revenue for fiscal 2023, and AT&T accounted for approximately 11.8% of our total revenue for fiscal 2024 and 10.6% of our total revenue for fiscal 2023.
As a result of efforts in recent years to diversify our business, the customer segments and geographies that comprise our customer base and top customers by revenue have changed.
During fiscal 2024, four cloud providers were among our top ten customers.
Cloud provider customers have been important contributors to our revenue through both our direct sales to them, including for data center interconnection, and their indirect impact on purchases by other network operators.
Because of our concentration of revenue with communications service providers and cloud providers, our business and results of operations can be significantly affected by market, industry, regulatory, consolidation or competitive dynamics adversely affecting these customer segments.
These dynamics have in the past had an adverse effect on network spending levels by certain of our largest customers and they could materially adversely affect our business and results of operations.
Consequently, our financial results and our ability to grow our business are closely correlated with the spending of a relatively small number of customers.
Our business and results of operations could be materially adversely impacted by the loss of a large customer within or outside of these customer segments as well as by reductions in spending or capital expenditure budgets, changes in network deployment plans, or changes in consumption models for acquiring networking solutions by our largest customers.
We face intense competition that could impact our sales and results of operations.
We expect our competitive landscape to continue to broaden as we seek to expand our addressable market and solutions portfolio.
We face intense global competition on a global basis, as we and our competitors aggressively seek to capture market share and displace incumbent equipment vendors.
Our industry has historically been dominated by a small number of very large vendors, some of which have substantially greater financial, marketing and research and development resources, broader product offerings and more established relationships with service providers and other customer segments than we do.
Moreover, acquisition activity among our competitors and peers has increased.
For example, in 2024 Nokia announced its proposed acquisition of Infinera.
Consolidation in our industry may result in competitors with greater resources, pricing flexibility, or other competitive benefits.
We also compete with a number of smaller companies that provide significant competition for specific products, applications, customer segments or geographic markets.
Due to the narrower focus of their efforts, these competitors may be more attractive to customers in a particular product niche or commercial opportunity.
Generally, competition in our markets is based on any one or a combination of the following factors: • functionality, speed, capacity, scalability and performance of network solutions; • the ability to meet business needs and drive successful outcomes, including meeting customer delivery time requirements; • price for performance, cost per bit and total cost of ownership of network solutions; • incumbency and strength of existing business relationships; • technology roadmap and forward innovation capacity, including the ability to invest significant sums in research and development; • time-to-market in delivering products and features; • company stability and financial health; • ability to offer comprehensive networking solutions, consisting of hardware, software and services; • flexibility and openness of platforms, including ease of integration, interoperability and integrated management; • ability to offer solutions that accommodate a range of different consumption models; • operating costs and total cost of ownership; • software and network automation capabilities; • ability to manage challenging supply chain environments, including manufacturing and lead-time capability; • services and support capabilities; • security of enterprise, product development, support processes, and products; • space requirements and power consumption of network solutions; and • ability to offer solutions that help customers manage the lifecycle impacts of their networks and achieve their sustainability goals.
We expect the competition in our industry to continue to broaden and to intensify, particularly as we seek to expand our addressable market opportunities, and as network operators pursue a diverse range of network strategies, sourcing practices and consumption models.
An increase in the breadth or intensity of competition we face may adversely impact our business and results of operations.
Our failure to invest in the right technologies or to get an adequate return on such research and development investment could adversely affect our revenue and profitability.
The market for communications networking hardware and software solutions is characterized by rapidly evolving technologies, changes in market demand and increasing adoption of software-based networking solutions.
