A newly filed Form 4 shows Paul Glavine, Chief Growth Officer of Cybin Inc. (CYBN), purchased 100,000 shares of company stock on the open market on September 3, 2026, at a price of $11.78 per share. The transaction, funded with Glavine’s own money rather than through options or other compensation mechanisms, totaled $1,178,280.00. Following the purchase, Glavine’s directly held stake stands at 4,171,252 shares.
This filing is not an isolated event. It is the latest in a short string of open-market purchases by Glavine, who has now bought shares on two separate occasions between August 31, 2026 and September 3, 2026. Combined, these two transactions add up to $2,220,957 in personal capital deployed into Cybin stock over just a few trading days. Our internal tracking flags this kind of repeated, closely timed buying activity from the same insider as a ‘cluster buy,’ a category we watch closely because it reflects sustained conviction rather than a single, potentially one-off decision.
Why Clustered Buying Gets Attention
A single insider purchase can be driven by any number of personal factors and does not necessarily signal anything about a company’s prospects. But when an executive returns to the market multiple times in a short window to buy more shares, it suggests a more deliberate pattern of accumulation. Academic research on insider trading has found that clustered buying activity, where several purchases occur close together in time, tends to correlate with above-average future stock performance more reliably than isolated purchases. That said, this correlation is a historical pattern observed across large datasets and is not a forecast or endorsement of any individual stock.
Glavine’s role as Chief Growth Officer places him in a position with direct visibility into Cybin’s commercial strategy and growth trajectory, which can add weight to insider purchases from that seat relative to more passive board-level holdings. The size of this particular purchase, over $1.1 million at a per-share price of $11.78, is also notable on its own, independent of the broader pattern.
Cybin Inc. trades under the ticker CYBN. This report is based solely on information disclosed in a Form 4 filing with the Securities and Exchange Commission and reflects the transaction details as reported. No additional information about the insider’s motivations or future trading plans was included in the filing, and readers should treat this as a record of disclosed activity rather than a signal to act on.
