Harmonic (NASDAQ:HLIT) reported Q2 non-GAAP gross margin of 53%, operating profit of $31.3M, and EPS of $0.21, including $2.3M stranded costs from the video business sale. CFO Walter Jankovic said two customers each exceeded 10% of revenue and together were 63%. Q3 broadband revenue guidance is $125M-$135M; full-year broadband $505M-$525M.
How this was made

The 30-second read
Why it matters
Key trading inputs are the updated Q3 and full-year guidance ranges, Q2 margin and operating profit including stranded costs, and cash-flow drivers from inventory and memory procurement.
Market read
Guidance ranges and cost/cash-flow explanations create actionable near-term positioning for HLIT around margin durability and broadband growth investment.
What to watch
Customer concentration remains high (two customers >10% each, 63% combined), so any churn or timing shifts in those accounts could outweigh the diversification narrative.
Background
Harmonic’s Q2 call focused on cOS platform flexibility across DOCSIS 3.1/4.0 and fiber, plus early traction in network intelligence products.
Ticker impact
Harmonic guided Q3 broadband revenue to $125M-$135M and full-year EPS to $0.67-$0.75, alongside Q2 margin and cash-flow details.
Likely choppy reaction risk around guidance range and margin/cash-flow implications, with upside if investors focus on fiber bookings and DOCSIS 4.0 ramp.
The article provides concrete guidance ranges, gross margin and operating profit, and explains free cash flow pressure from inventory build and memory costs not passed through to customers.
Market effects
DOCSIS 4.0 interoperability milestone and fiber bookings reinforce broadband infrastructure capex demand signals for cable and access-network vendors.
Named live deployments (Finland, Venezuela) suggest ongoing international rollout momentum, though scale is not quantified.
Network-architecture flexibility (DOCSIS 4.0, extended DOCSIS 3.1, fiber) supports broader global broadband modernization narratives.
Counterpoint
Investors may discount early intelligence-product adoption and treat negative free cash flow and memory-cost drag as a recurring pattern rather than a temporary working-capital issue.
