DiBella John Anthony II 4

What Happened
John Anthony DiBella II, Chief Revenue Officer of Simulations Plus, sold 1,000 shares of SLP in an open-market transaction on June 3, 2026. The shares were sold at $16.50 each, for total proceeds of $16,500. This was a sale (not a purchase); sales by insiders can be routine (e.g., for diversification or planned liquidity) and do not necessarily indicate a change in company outlook.

Key Details

• Transaction date and price: June 3, 2026 — 1,000 shares sold at $16.50 per share.
• Total value: $16,500.
• Method: Open market sale (reported as a sale).
• Shares owned after transaction: Not specified in the provided filing.
• Footnotes: F1 — sale was effected automatically under a Rule 10b5-1 trading plan; F2 — all shares sold in a single transaction at $16.50.
• Filing timeliness: Form filed June 4, 2026 (within the standard 2-business-day window), so appears timely.

Context

• The 10b5-1 plan note means the trade was pre-authorized under a formal trading plan, which is commonly used by insiders to schedule trades and reduce concerns about opportunistic timing.
• For retail investors, purchases by insiders often attract more attention as potential positive signals; routine sales under pre-set plans are common and do not by themselves imply negative insider sentiment.
