Harmonic (HLIT) GC Timothy Chu Converts RSUs; Shares Withheld for Taxes

What Happened

  • Timothy C. Chu, General Counsel and SVP Human Resources of Harmonic Inc. (HLIT), had restricted stock units convert to common shares on May 15, 2026. The filing shows derivative conversions/exercises totaling 19,752 RSUs into shares (entries of 9,876 acquired and 6,053 and 3,823 listed as disposals), and 3,475 shares were surrendered/withheld to satisfy tax withholding at $12.54 per share (total $43,577). No cash proceeds to Mr. Chu were reported from the disposal entries.

Key Details

  • Transaction date: 2026-05-15; Form 4 filed: 2026-05-19 (filed within the standard two business days after the transaction).
  • Reported prices: tax-withheld shares disposed at $12.54 each (3,475 shares = $43,577); other derivative disposals listed at $0.00 (administrative/net settlement).
  • Footnote: F1 — each restricted stock unit (RSU) represents a contingent right to receive one share of HLIT common stock.
  • Shares owned after the transaction: not specified in the data provided.
  • Filing timeliness: filing appears timely (May 19 filing for a May 15 transaction).

Context

  • This appears to be a routine vesting/conversion of RSUs with company withholding of shares to satisfy tax obligations (a common administrative step), not an open-market sale or purchase. The $43.6K reported is the tax withholding value; there were no reported cash sales proceeds to the insider.
