Significance 5/10

Director David Krall buys 47,528 shares of HLIT at $10.50; now holds 223,125 shares post-transaction (+27.1%).

Director David Krall purchased 47,528 shares at $10.50 on 2025-12-11, increasing his holdings by 27.1% to 223,125 shares total. The transaction occurred near the lower end of the 52-week range ($8.25–$13.70), with the stock currently trading at $10.46, -23.6% from the 52-week high. His prior buy at HLIT on 2025-02-13 delivered a -1.9% 90-day return, and his cross-ticker track record shows a 0.00% win rate on prior buys at the 90-day mark (2 prior buys, avg 90d return -3.5%), indicating a pattern of purchases that have not appreciated as intended. The company trades at P/E 23.77 with recent quarterly revenue of $142.4M and modest net income of $2.7M, suggesting an elevated valuation relative to current earnings generation. This purchase represents a material open-market accumulation by a director, though his track record of prior buy timing offers limited evidence that it will lead to subsequent gains.

Director Whalen Daniel T buys 2,000 HLIT shares at $8.25; stock down -41.8% from 52-week high.

Whalen acquired 2,000 shares on 2025-08-01 at $8.25, increasing holdings by 16.9% to 13.8K shares.

Whalen's prior trades at HLIT (4 buys since February 2025) show a timing pattern of 0 wins at the 90-day mark, with three completed outcomes ranging from -10.5% to -12.3%, suggesting prior purchases have not preceded price appreciation. The company shows moderate fundamentals with $138.0M revenue, net income of $2.9M, and 11.6% annual revenue growth, though the current P/E of 14.38 suggests the market may reflect recent weakness.

Director Whalen buys 2,000 HLIT shares at $8.99; stock now -38.9% from 52-week high after -10.5% decline post-prior Feb purchase

Whalen Daniel T (Director) purchased 2,000 shares at $8.99 on 2025-05-30, increasing his holdings by 20.3% to 11,840 shares. The current price of $9.05 is -38.9% from the 52-week high of $14.82, reflecting significant downside movement. His prior trade timing at HLIT shows a consistent pattern of underperformance: his three prior buys at this ticker each posted negative 90-day returns (ranging from -10.5% to -12.3%), with a 0.00% win rate at the 90-day mark. This fresh purchase occurs as the stock trades near its 52-week low, and his cross-ticker buy track record shows an identical 0.00% 90-day win rate with an average 90-day return of -11.4%, raising questions about whether this accumulation reflects conviction or follows a pattern of purchasing decisions that have not generated positive forward returns.

Significance 6/10

Director Whalen Daniel T purchases 1,000 shares of HLIT at $9.99; cluster pattern with 3 other insiders buying within 14 days as stock down -12.2% in 30 days.

Director Whalen Daniel T purchased 1,000 shares at $9.99 on 2025-02-25, increasing holdings from 8,840 to 9,840 shares. This transaction is part of a broader cluster pattern: 3 other insiders also bought within the past 14 days, and the FACTS note 2 prior buys at HLIT by this director on 2025-02-24, suggesting coordinated or near-simultaneous accumulation activity. The timing occurs after the stock has declined -12.2% over the past 30 days and -19.2% over 90 days, falling to $10.15 from a 52-week high of $14.82. The company's fundamentals show revenue of $195.8M and net income of $21.7M with annual revenue growth of +11.6%, though valuation remains elevated at a P/E of 29.85. The cluster activity warrants monitoring to assess whether multiple insiders view the recent price decline as a buying opportunity or whether the transactions signal forward-looking expectations about the business trajectory.

HLIT Director Whalen purchased 3,000 shares for $30,458.90 on 2025-02-24; cluster of 3 other insiders buying within 14 days

Daniel T Whalen, a director at Harmonic Inc, completed 2 separate purchases totaling 3,000 shares (3.0K shares) for $30,458.90 at a blended average price of $10.15, expanding his holdings from 5,840 shares to 8,840 shares (a +51.4% increase).

Notably, 3 other insiders filed purchases within the same 14-day window, indicating a coordinated insider accumulation pattern at Harmonic, a company with trailing quarterly revenue of $195.8M and net income of $21.7M. This cluster activity, combined with Whalen's substantial increase in his personal stake, suggests aligned insider perspective on valuation and forward outlook, though the stock has declined 15.1% over the past 30 days and 19.5% over 90 days.

CFO Jankovic buys 12,000 shares at $9.44 across 2 transactions; coincides with cluster of insider buying

Jankovic Walter, Chief Financial Officer of Harmonic Inc, executed 2 separate purchases totaling 12,000 shares for $113,279.50 at $9.44 on 2025-02-12, expanding his holdings from 34,129 shares to 46,129 shares (+35.2% increase). The stock is currently trading at $9.79, down -33.9% from its 52-week high of $14.82 and down -20.8% over the prior 30 days. A cluster pattern is active: 2 other insiders also bought within the past 14 days. The company is modestly profitable with net income of $21,718,000.00 against revenue of $195,756,000.00 (latest quarter) and a P/E of 13.41, but faces headwinds with annual revenue declining -2.7% year-over-year. The contemporaneous buying by multiple insiders during a period of significant recent price weakness and alongside declining revenue growth merits investor monitoring.

CEO Nimrod buys 7,780 shares at $9.65 avg for $75.1K as stock down -20.8% in 30 days

Ben-Natan Nimrod, President and CEO of Harmonic Inc, executed 4 separate purchases totaling 7,780 shares for $75,060.93 on 2025-02-13 at an average price of $9.65, increasing his holdings to 347,797 shares (+2.3%). The timing coincides with material near-term price weakness: the stock has declined -20.8% over the preceding 30 days and trades at $9.79, a discount of -33.9% from its 52-week high of $14.82. Additionally, a cluster pattern shows 2 other insiders bought within the past 14 days, suggesting broader insider appetite at depressed levels. Company fundamentals appear stable with $195.8M in latest quarterly revenue and $21.7M net income, though annual revenue growth stands at -2.7% and the stock trades at a P/E of 13.41, reflecting modest valuation. The CEO's open-market history shows 2 prior sells with a 100% well-timed rate at the 90-day mark, suggesting demonstrated timing acumen, though this buy's ultimate performance cannot be characterized as well-timed or poorly-timed until 90 days elapse.
