Raymond James sees Charter capex benefiting Harmonic, AAOI shares

Charter Communications’ Q1 2026 cable capex came in at $2.86B, above Raymond James’ $2.68B estimate and up 19% year over year, while Charter reaffirmed full-year 2026 capex guidance at $11.4B and signaled a drop to roughly $7.5B-$8.0B by 2028. The report is constructive for equipment vendors such as Harmonic, Ciena, Nokia, and Applied Optoelectronics, with Harmonic getting extra support from recent analyst upgrades and a consensus target implying about 25% upside. Harmonic also reported strong broadband execution, including record bookings and a 3.5x book-to-bill ratio, while its Video business sale remains on track for completion in 1H 2026.

Analysis

The key signal is not the modest capex guide itself, but the sequencing: broadband infrastructure spend is holding up now while management is explicitly telegraphing a steeper downshift later. That creates a two-stage trade for vendors: near-term order visibility stays intact, but the forward multiples for names exposed to a single cable customer should compress once investors start discounting 2027-2028 air pockets. The market is likely still underpricing how quickly sentiment can rotate from “capex resilient” to “capex cliff” once the Street sees a second consecutive year of flat-to-down operator spending.

HLIT is the cleanest beneficiary because its broadband-only profile removes video dilution and forces the market to focus on the part of the business most leveraged to cable upgrade cycles. The asymmetric setup is that any incremental spend on scalable infrastructure disproportionately flows to a narrower set of incumbents with proven execution, while weaker adjacent suppliers face share loss even if the overall pie is only flat. By contrast, AAOI and CIEN are more exposed to timing risk: if charter-like spend is pulled forward today, their upside is mostly a near-term estimate reset, not a durable growth re-rate.

The contrarian read is that the market may be overreacting to the “down meaningfully beyond 2026” headline and underestimating the optionality from customer churn. Broadband net adds deteriorating this fast can force operators to spend defensively on network quality and retention, which supports vendor orders even in a down-capex environment. The bigger risk is not lower cable capex per se, but a slower-than-expected pass-through from capex to vendor revenue if operators prioritize software, maintenance, or internal productivity over new hardware.

This is a months-long, not days-long, setup: the next catalyst is whether peer operators echo Charter’s tone on 2027 budgets and whether vendors guide conservatively or reaffirm backlog strength. If multiple operators validate the same capex glidepath, the trade shifts from single-name alpha to sector de-rating; if not, HLIT can keep screening as a relative winner on execution and mix.

Key Decisions for Investors

• Long HLIT vs short CIEN as a relative-value pair for the next 1-3 months: HLIT has cleaner broadband leverage and better revision momentum, while CIEN is more vulnerable if cable capex starts to normalize down.
• Use any 5%-8% pullback in HLIT to add exposure, targeting a 2:1 upside/downside over 6-10 weeks if broadband bookings stay strong and the market keeps rewarding post-video simplification.
• Short a basket of cable-exposed equipment names that are most dependent on 2027 capex optimism; pair against XLK or a telecom infrastructure ETF to isolate operator-spend risk from broader tech beta.
• For AAOI, trade it tactically only on order-flow confirmation: buy dips after positive vendor commentary, but treat it as a 1-2 quarter trade because the catalyst is timing, not structural share gain.
