[Form 4] OSI Systems Inc Insider Trading Activity

Rhea-AI Filing Summary

OSI Systems, Inc. (OSIS) – Form 4 insider filing

• Insider: Cary M. Okawa, Chief Accounting Officer
• Transaction date: 08/01/2025
• Type: Acquisition of restricted stock units (RSUs), coded “A” (award/compensation)
• Quantity: 615 common shares
• Price indicated: $219.57 per share (reference price in filing)
• Post-transaction holdings: 3,074 shares, held directly
• RSUs were granted under the company’s 2012 Incentive Award Plan and will vest only if performance targets are achieved.

The filing reflects a routine equity incentive grant to a senior officer rather than an open-market purchase. No derivative securities were reported.

Positive

• Equity alignment: Performance-based RSUs tie senior management compensation to shareholder returns.
• Minimal dilution: 615 shares are immaterial relative to OSIS’s total shares outstanding.

Negative

• Non-open-market: Awarded shares do not indicate proactive insider confidence through personal capital deployment.

Insights

Equity Compensation Analyst

TL;DR: Standard RSU grant, modest size, neutral signal.

The 615-share RSU award to CAO Cary Okawa represents ~0.01% of OSIS’s 18 mn share count and brings his direct ownership to just over 3k shares. Because the shares are contingent on future performance, dilution is deferred and aligns management incentives with shareholders. However, the transaction is compensation-related, not a discretionary buy, so it offers limited insight into insider sentiment. Given its small size and routine nature, the market impact should be negligible.
