TWLO director drops $184M and INFQ insiders complete $381M cluster exit
Twilio director Andrew Stafman sold $184M in a near-complete stake exit while Infleqtion's three-insider cluster (Maverick + Singer + CEO) reached $381M total. The AI/semiconductor insider sell wave extended across ASX, MPWR, ARM, DIOD, and VICR for a two-day total exceeding $230M. On the buy side, Gibraltar Industries (ROCK) triggered its first-ever insider cluster buy, TXO's Bob Simpson extended a 6-buy streak, and WW International stretched accumulation to five buyers. Fortune Brands launched a Fiberon strategic review with Ed Garden's $15.66M buy as backdrop; Forager Fund published a public shareholder letter at RPAY after the board rejected its $4.80 offer.
The May 27–28 window delivered the heaviest single-session insider selling of the week. Twilio (TWLO) director Andrew Stafman liquidated $184M in a near-complete exit, while Infleqtion (INFQ) added two more sellers on top of Maverick Capital's $186M move from yesterday — pushing the three-insider cluster total to $381M. The AI/semiconductor insider sell wave kept rolling: ASX, MPWR, ARM, DIOD, and VICR together contributed another leg, extending the two-day semi cluster to more than $230M. On the buy side, Gibraltar Industries (ROCK) triggered a brand-new three-insider cluster, TXO's Bob Simpson added to a 6-buy streak, and WW International stretched its accumulation to five separate buyers.

INFQ: three-insider, three-day, $381M — the cluster is complete
Yesterday covered Maverick Capital's $186M Infleqtion exit. Two more filings landed May 28 to close the loop.
Director David B. Singer sold 11,619,130 shares at $15.63, collecting $181.60M and cutting his stake by 59.12% 1. This was Singer's single largest Form 4 sale out of 44 all-time transactions — a meaningful threshold given his transaction history. On the same day, the CEO sold 769,954 shares at $17.03 for $13.12M (-11.58%) — his first insider sale ever 1.
Combined with Maverick's $186.01M on May 27, the three-day cluster total reaches $380.73M across three insiders 2. All three transactions cut positions by roughly 59–60%. INFQ rose approximately +38% in the week prior to the May 28 sales.
A few observations worth separating from inference: the stake-percentage cuts across all three filers are nearly identical (59–61%), which is consistent with a coordinated partial liquidation rather than independent decisions. The CEO sale being a first-ever makes it harder to attribute to a routine plan. That said, Infleqtion is a private-origin quantum computing company that came to market relatively recently, and pre-IPO holder lockup expirations or secondary windows can produce synchronized selling that doesn't necessarily reflect a change in fundamental view — the available data doesn't confirm either interpretation 3.
TWLO: director Stafman exits $184M — the largest standalone move of the day
Twilio (TWLO — the cloud communications platform for SMS, voice, and email APIs) director Andrew Stafman sold 1,000,000 shares at $184.14 on May 27, taking $184.14M and reducing his position by 61.22% 1. This was the largest of his three all-time Form 4 transactions. TWLO had gained approximately +27.34% in the month prior to the sale.
Three insiders at TWLO completed five separate sales in the past 30 days, so Stafman's transaction isn't isolated. The 61.22% stake cut at the director level, following a strong multi-week rally, fits the distribution pattern seen in the INFQ and MPWR filings in this window.

AI/semiconductor insider sell wave: two-day total exceeds $230M
A multi-name pattern has now accumulated across two filing days:
| Ticker | Company | Insider(s) | Value | 30-day context |
|---|---|---|---|---|
| ASX | ASE Technology Holding Co. (semiconductor packaging) | Director Jeffrey Chen | $17.13M | 4 sales / 30 days; stock +28.36% prior week 1 |
| MPWR | Monolithic Power Systems (power management ICs) | EVP/GC $7.93M + Director Zhou $816K | $8.75M | 8 insiders / 11 sales in 30 days; stock +45.82% in 3 months 1 |
| ARM | Arm Holdings (chip architecture licensor) | CCO $703K | $703K | 5 insiders / 10 sales in 30 days; stock +44.08% prior week 2 |
| DIOD | Diodes Inc. (analog semiconductors) | CTO $997K + President Diodes Asia $394K | $1.39M | 6 insiders / 11 sales in 30 days; stock +59.94% in 3 months 1 |
| VICR | Vicor Corp. (power conversion) | VP Marketing $1.51M | $1.51M | 13 insiders / 23 sales in 30 days; stock +26.02% prior week 1 |
The common thread is straightforward: stocks up 26–60% over recent periods, and insiders selling into strength. This is consistent with post-rally profit-taking and does not by itself indicate a view on the sector's forward direction. What makes it worth tracking is the breadth — five distinct companies across the semiconductor value chain, all disclosing in the same two-day window.
Cluster buys: ROCK (new), TXO (ongoing), WW (expanding)
The buy side is quieter in dollar terms but shows real conviction clustering.
ROCK — Gibraltar Industries (building products manufacturer — residential solar, ventilation, residential roofing): CEO purchased 19,735 shares at $37.44 for $738,830 on May 27, his single largest Form 4 buy across three all-time transactions 1. Three insiders have made three total purchases in the past 30 days — the first time ROCK has triggered a cluster buy signal. New cluster signals on names without prior insider buy history carry slightly more weight than continuation of an existing pattern; a CEO record buy as the cluster trigger adds to that read.
TXO Partners (oil and gas royalty partnership): Director Bob R. Simpson bought 65,592 shares at $13.20 for $866,050 1. Two insiders have made six total purchases in the last 30 days. Simpson's buy history in TXO is extensive (18 all-time transactions), and the current cadence — six buys in 30 days across two insiders — is elevated relative to typical ongoing accumulation.
WW International (Weight Watchers — the consumer wellness and weight management company): Director Eugene I. Davis bought 21,648 shares at $13.66 for $295,800, his second-largest Form 4 purchase out of three 1. Five insiders have now made five separate purchases in the past 30 days, each buying into a stock that fell approximately -34.90% over the prior three months. The current price of $15.15 vs. the Davis transaction price of $13.66 implies a +10.88% paper gain on that specific buy since execution.
FBIN + Ed Garden: strategic review cross-signal
Fortune Brands Innovations (FBIN — home products, including MasterBrand cabinetry and Moen faucets) announced on May 27 that it is conducting a formal strategic review of its Fiberon composite decking business 4. Interim CEO David Barry stated the review is intended to "sharpen focus on core platforms that drive profitable growth."
The read-across is with Ed Garden (Trian Fund Management co-founder), who bought approximately $15.66M of FBIN stock around its 52-week low on May 21–22, accumulating roughly 466,300 shares at a weighted average near $34.89 5. Garden joined the FBIN board in March 2026 via a cooperation agreement. His current holding of approximately 3.62M shares (about 3.1% of outstanding) sits below the 5% threshold that would require a 13D/G filing.
The portfolio action — a strategic review of a non-core asset — occurred shortly after a Trian-affiliated director made a multi-million dollar purchase near the stock's low. Whether the Fiberon review was influenced by or independent of that board relationship is not stated in the public filing. FBIN has not set a completion timetable for the review, and no transaction outcome is guaranteed.

RPAY: Forager goes public, board has not responded
Forager Fund (a value-oriented activist firm based in New York) filed a fifth 13D amendment on May 27 and simultaneously published a public shareholder letter addressed to Repay Holdings (RPAY — a payment processing company serving consumer finance, healthcare, and government verticals) stockholders 6.
Forager holds 11,106,648 shares, representing 12.4% of RPAY's Class A common stock. Its $4.80 per share all-cash acquisition offer carries roughly a 28% premium over RPAY's May 27 closing price of approximately $3.75. The RPAY board previously rejected the offer, characterizing it as "grossly undervaluing" the company.
Forager's public statement said the firm "continues to believe that a transaction involving the Issuer may be in the best interests of stockholders and remains willing to engage in discussions regarding a potential transaction." 6 As of the close of this window, the RPAY board had not publicly responded.
The standoff structure is now: a 12.4% holder with a $4.80 bid, a board rejection, a public letter, and silence from the company. The next observable step would be either a board response, a proxy move, or a revised bid.
