Three OneMedNet Corp ($ONMD) insiders collectively purchased roughly $352,000 worth of shares across six open-market transactions between June 12 and June 23, 2026, according to Form 4 filings disclosed to the SEC on June 24. The buyers were Chief Executive Officer Aaron Green, Chief Medical Officer Jeffrey Yu, and director Thomas Kosasa.
Yu was the largest buyer in the cluster, executing two purchases that totaled approximately $200,000. His first transaction, on June 16, was 172,414 shares at $0.58 per share for roughly $100,000. His second, on June 23, was 158,730 shares at $0.63 per share — again near $100,000. Following those transactions, Yu held approximately 8.78 million shares of the health care data company.
Kosasa, a board director, made one purchase on June 12: 158,730 shares at $0.63 per share for approximately $100,000. His holdings after that transaction stood at roughly 17.09 million shares, making him the largest reported holder among the three.
Green, the CEO, spread his activity across three trades spanning the full window. He purchased 36,920 shares at $0.5581 on June 12 ($20,605), followed by 18,702 shares at $0.5396 on June 15 ($10,092), and then 36,650 shares at $0.5733 on June 23 (~$21,011). His combined outlay over the 12 days was approximately $51,708, bringing his position to roughly 1.90 million shares.
All six transactions were flagged as open-market trades, and each Form 4 was filed the day after the corresponding transaction date or within one business day.
The June 2026 activity is not the first time multiple $ONMD insiders have bought shares in close proximity. In June 2025, Yu and Kosasa each made large open-market purchases on the same day — June 20 — with Yu acquiring approximately $700,000 worth and Kosasa approximately $500,000 worth at $0.42 per share. Kosasa has also made consecutive quarterly purchases in April and May 2026, adding roughly $250,000 worth of shares in each month. Yu's April 2026 purchase of 903,614 shares added approximately $750,000 to his position. Green's most recent prior open-market trades on the stock were sales in October and November 2025, making his June 2026 purchases a reversal in direction for the CEO.
OneMedNet Corp operates in the health care sector. The six cluster transactions bring the three insiders' combined open-market purchases in 2026 alone to well over $1 million at the midpoint of reported prices.
