Lie Sean, Chief Technology Officer of CBRS, has filed 71 Form 4 transactions, all in a single company, with a total sell value of $193.6 million and zero open-market purchases. The pattern is one-sided: every recent trade with a dollar value attached is a sale, and the only other codes are mechanical or non-cash events such as option exercises (M), gifts (G), and conversions (C). There are no buys under code P, and no shares acquired through grants or awards in the data provided.
The most concentrated selling occurred on September 25, 2026, when Sean executed eight open-market sales totaling roughly $23.8 million, with individual transactions ranging from $106,070 to $6.43 million. That same day also included three option exercises with zero reported value, a gift, and a conversion. Earlier sales in September and August followed the same shape: on September 4, a single sale brought in $11.2 million, and on August 21, another sale added $3.4 million. The August 20 filings show four option exercises with no cash value, which typically precede the sale of the underlying shares.
Across the recent window, the 11 sales with recorded values sum to approximately $48.6 million, all in CBRS. The absence of any purchase activity, combined with the regular cadence of option exercises followed by large sales, points to a consistent disposition of equity rather than accumulation. The data does not indicate any open-market buying at any point in the filing history.
