Harmonic Inc: what insiders have been doing
This page follows insider dealings at Harmonic Inc as filed with SEC (Form 4), a company from the Technology sector based in San Jose, United States. The group dates from 1988. Between 18 October 2025 and 18 October 2026, 9 insiders published 39 filings.
On the market, 1 insider bought (1 purchase totalling €426k) while 1 insider sold (2 sales totalling €415k). Purchases outweigh sales by €12k. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Those buying include 1 senior executive. One trade stands out by size: a purchase of €426k from Krall David, disclosed on 15 December 2025.
Compared with its exchange (5,458 companies, median 22 filings), a count of 39 filings is above the norm. Our records for Harmonic Inc go back to 2021, with 8 purchases and 24 sales on the open market in total. In its latest annual report filed with the SEC (10-K, fiscal year ended 31 December 2025), the company reported revenue of 360.5 m USD and net income of -43.3 m USD.
The latest purchase dates back some time: it was published 307 days ago, on 15 December 2025. Typically, a trade is published a median of 3 days after it takes place. For comparison, the SEC allows two business days to file a Form 4. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning.

About Harmonic Inc
Harmonic Inc. (NASDAQ: HLIT) is a U.S.-listed technology company headquartered in San Jose, California, United States, with operations focused on broadband infrastructure and video delivery. The company has built its business around two main segments: Broadband and Video. Its Broadband unit provides software-based broadband access solutions and related services, anchored by the cOS platform, which helps cable operators and telecom providers virtualize access networks, accelerate DOCSIS 4.0 rollouts, support fiber-deep architectures, and deliver multi-gigabit services. The Video segment offers video processing, production, playout, encoding, and SaaS-based streaming and broadcast solutions for media companies, pay-TV operators, and streaming platforms.
Harmonic was founded in the Silicon Valley technology ecosystem and has evolved from a more hardware-centric networking and video vendor into a company increasingly centered on software, cloud-native architectures, and virtualized network solutions. That strategic shift reflects two durable industry trends: the secular rise in broadband traffic and the ongoing migration of video consumption from traditional broadcast channels to OTT and streaming workflows. In practical terms, Harmonic’s products are designed to help operators modernize legacy infrastructure, simplify operations, improve scalability, and lower the cost of delivering high-bandwidth services.

From a competitive standpoint, Harmonic occupies a specialized but important position. In broadband, it is a well-recognized supplier to cable and telecom operators pursuing next-generation access upgrades and network virtualization. In video, it serves broadcasters, media groups, and service providers that need efficient content processing, live event delivery, and monetization tools, including targeted advertising and cloud-based playout workflows. The company’s customer base is global, with commercial activity across North America, Europe, Latin America, the Middle East, and Asia-Pacific.
Recent developments have been strategically significant. In early 2026, Harmonic announced an agreement to sell its Video business to MediaKind for $145 million in cash, a move that appears designed to sharpen management focus and capital allocation toward the Broadband business. The company also reported strong end-2025 momentum in Broadband, including record quarterly bookings, a 3.5 book-to-bill ratio in the fourth quarter of 2025, and a materially higher backlog, all of which improve visibility into 2026 revenue trends. For investors, Harmonic is best viewed as a U.S. technology infrastructure play exposed to broadband modernization, fiber expansion, and the ongoing reconfiguration of the video distribution market.
