RMBS RAMBUS INC Insider Trading

Director Emiko Higashi sold 10,000 RMBS shares (2 transactions) for $1,605,000.00, reducing stake 16.8% amid 53.1% 30-day rally

Director Emiko Higashi executed 2 separate sales totaling 10,000 shares for $1,605,000.00 on June 2, 2026, at prices of $163.00 and $158.00, reducing her post-transaction holdings to 49,519 shares from 59,519 shares (a 16.8% reduction in her stake). The sales occurred during a period of significant momentum: the stock has risen 53.1% over the prior 30 days and 85.7% over the prior 90 days, currently trading at $170.66—near the 52-week high of $167.71. The transactions were executed below the current price, but the company's fundamentals show strong operational performance with quarterly revenue of $180,189,000.00 and net income of $59,858,000.00, though the elevated 80.12 P/E ratio reflects significant market pricing. The scale of the reduction (16.8% of holdings) in a rising market context warrants investor attention to director positioning and conviction levels.

Xianzhi Sean Fan (EVP, COO) sells 37,914 shares at $151.69 avg for $5.8M; holds 168,358 shares post-trade

EVP and COO Xianzhi Sean Fan executed 2 separate sales totaling 37,914 shares for $5,751,225.53, reducing his holdings by 18.4% from 206,272 to 168,358 shares. His cross-ticker track record shows a 100.00% well-timed rate across 7 prior sells (average 90d return -14.2%), and at RMBS specifically, 3 of 3 prior measurable sells were well-timed, with the most recent sale on 2025-02-19 realizing a 90d return of -18.2%. The current share price of $157.23 sits 2.8% below the 52-week high of $161.80, and the stock has gained 55.5% over the past 90 days. His substantial reduction in stake amid strong recent performance and consistent prior sell timing warrants investor attention to whether this represents a shift in executive conviction at a company trading at a P/E of 73.82.

Director Sayiner Necip sold nearly 10,000 shares of RMBS for $1.28M, his 7th open-market sale in three years.

Sayiner Necip, a director at Rambus, sold a meaningful stake totaling approximately $1.28 million, representing nearly 30% of his holdings. This is his seventh open-market sale over the past three years—a consistent pattern of disposition with no countervailing open-market purchases during that window. The sale occurred while the stock trades noticeably below its 52-week high and in the midst of a strong recent rally that accelerated over both the past three months and past month. The company itself presents healthy fundamentals: it is profitable with meaningful annual net income and has demonstrated strong revenue growth, though the stock trades at a stretched valuation multiple. The timing of the sale during a period of strength, combined with Necip's established pattern of regular selling, suggests a director maintaining a gradual reduction in holdings rather than a response to recent weakness or operational concern.
