In June 2026, Harmonic Inc. NASDAQ:HLIT finally cut the cord. By selling its legacy video business for nearly $138 million, the company transformed into a pure-play bet on the guts of the internet. It no longer has to split its focus between media software and cable hardware. Now, it is all about cOS, a software platform that lets cable giants modernize their networks without ripping out every mile of copper. As network traffic grows and shifts upstream, the company stands at the intersection of cable survival and fiber expansion.
Potential Bull Cases
1. The Converged Platform Ends the Civil War Between Cable and Fiber
Operators used to face a binary choice: stick with old cable tech or rip everything out for fiber. This company solved that headache with its cOS software, which lets providers run both architectures simultaneously. Management reported that 161 customers now use the system to reach 48 million devices. Operators love this flexibility because they can test different network upgrades side by side without wasting money on redundant hardware. It turns a risky technology bet into a simple software update. This converged approach makes the platform extremely sticky as customers evolve their networks over several years. The platform is the system of record for these providers.
2. Rest-of-Market Growth Reduces Dependence on the Biggest Customers
For years, the story was dominated by two massive accounts, Comcast and Charter. The narrative is changing as the company wins business elsewhere. In the second quarter of 2026, revenue from the rest of the market jumped 44% to nearly $50 million. This group now represents 37% of total revenue. More importantly, these customers accounted for 60% of new bookings during the quarter. This diversification reduces the risk that a single budget pause at a tier-one provider will crater the business. The company is successfully proving that its technology works for regional providers and global operators, not just the giants.
3. New Fiber Products Are Moving Into the Field
The company is not just a cable play anymore. It recently secured its first multimillion-dollar orders for the Pearl-1XL and Oyster+ fiber products. These devices are designed for the outdoors and include power protection to keep service running during outages. This ruggedized design lets operators skip the expensive street cabinets that typically house fiber equipment. By moving the tech closer to the customer, providers can deploy multi-gigabit speeds faster and at a lower cost. This move into carrier infrastructure for mobile operators and nationwide fiber providers expands the total addressable market beyond traditional residential broadband services.
4. Software Intelligence Creates High-Margin Recurring Revenue
Beyond the hardware nodes and software cores, the company is building an intelligence layer that is becoming a material part of the business. Its Beacon platform is now live with 20 customers. Early results show a 30% reduction in service calls for operators who use it. This software gives providers real-time visibility into their plant and amplifiers. It turns a reactive maintenance model into a proactive one. Because this is high-margin software revenue, it should provide significant operating leverage as it scales. Management expects this intelligence layer to become a material contributor to recurring revenue as more operators instrument their plants.
5. Massive Backlog Provides Clear Visibility Into 2027
The company ended the second quarter of 2026 with a record backlog and deferred revenue of nearly $588 million. This represents a 71% increase compared to the previous year. About 73% of that backlog is expected to convert to revenue within the next 12 months. This visibility gave management the confidence to raise its full-year 2026 revenue guidance to a range of $505 million to $525 million. It also expects non-GAAP earnings per share to land between $0.67 and $0.75 for the year. This level of contracted work suggests that the growth story has a long runway regardless of near-term economic shifts.
Potential Bear Cases
1. High Customer Concentration Still Poses a Major Risk
Despite the growth in other areas, two customers still account for 63% of total revenue. This concentration remains a heavy anchor on the business. If either of these giants decides to slow its capital spending or delay its upgrade cycle, the company has almost no way to offset the loss. We saw this dynamic in previous years when large operators paused deployments to digest inventory. The rest of the market is growing, but it is not yet large enough to carry the company if a primary partner changes strategy. The fate of the stock is still tied to the whims of two boardroom decisions.
2. Rising Memory Costs Act as a Persistent Tax on Profits
Global supply chain issues are hitting the bottom line through higher component prices. Management expects to take a $3 million hit per quarter in the second half of 2026 due to the rising cost of memory. While the team has already secured the supply needed for the rest of the year, it is paying market prices that eat into gross margins. The company cannot always pass these costs through to customers immediately. If component pricing remains elevated into 2027, the operating leverage that investors expect from a software-led transition could fail to materialize. The hardware side of the business still carries real-world inflation risks.
3. Stranded Costs From the Video Sale Weigh on Earnings
The divestiture of the video business was a strategic win, but it left behind $10 million in stranded costs for 2026. These are expenses that used to be shared between the two segments but now fall entirely on the broadband business. Management believes it can eliminate about 30% of these costs within a year of the closing, but the remainder must be absorbed or cut through restructuring. Cleaning up the corporate structure after a major sale is often messier and more expensive than it looks on paper. These costs will act as a drag on profitability while the company navigates its first year as a pure-play operation.
The Moneyball Verdict: 54 out of 100
Our proprietary Moneyball scoring system assigns Harmonic an overall Superscore of 54 out of 100, placing it in the Average category. The Superscore is an AI-powered score that evaluates a company's overall strength by combining financial performance, product market position, technological capabilities, leadership quality, and relative valuation.

The average rating for Harmonic corroborates the bear thesis and highlights a business that hasn't yet escaped its greatest vulnerability. It underscores the threat of customer concentration, a structural risk that outweighs the recent progress in its new fiber and software offerings. While management is adding smaller accounts, the company still relies on two giants for 63% of its revenue.
