Employee Stock Purchase Plan financial

"These shares were acquired on September 3, 2026 through the Gran Tierra Inc. Employee Stock Purchase Plan"

An employee stock purchase plan is a company program that lets workers buy shares through small payroll deductions, often at a discount to the market price and after a set offering period. Think of it like a workplace savings plan that turns into ownership: it encourages employees to share in the company’s success and can create predictable buying or selling of stock that investors watch because it affects supply, demand and employee incentives.

Rule 16b-3(d) regulatory

"in a transaction that was exempt under both Rule 16b-3(d) and Rule 16b-3(c)"

Rule 16b-3(d) is a narrow SEC safe-harbor that shields company insiders (officers, directors and large shareholders) from liability for short‑swing profits when their buys or sells of company stock are made under a pre-established, written plan or contract that removes the insider’s ability to time trades. For investors, this matters because it permits predictable, automated insider transactions — like scheduled sales for diversification or payroll withholding — without triggering forced disgorgement, so such planned trades are treated differently from opportunistic insider trading.

Rule 16b-3(c) regulatory

"in a transaction that was exempt under both Rule 16b-3(d) and Rule 16b-3(c)"

An SEC rule that lets corporate insiders avoid automatic "short‑swing" profit recovery when they buy or sell their company’s stock under a pre‑approved, written plan that meets specific conditions. For investors, it matters because it clarifies when insider trades are treated as routine, reducing legal uncertainty and helping distinguish trades made for ordinary compensation or pre‑planned reasons from those that might signal opportunistic or timely insider advantage.
