Employee Stock Purchase Plan financial

"These shares were acquired on May 19, 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.

Jim Evans reported receiving 146 Gran Tierra Energy common shares as a stock purchase plan award. The shares were acquired on May 19, 2026 at a price of $9.31 per share under the company’s Employee Stock Purchase Plan, rather than through an open-market trade.

How many GTE shares does Jim Evans hold after this Form 4 filing?

After the May 19, 2026 award, Jim Evans directly holds 48,987 Gran Tierra Energy common shares. The Form 4 also discloses an additional 3,200 shares held indirectly by his spouse, reflecting family-related beneficial ownership separate from his direct personal holdings.

What was the price for the Gran Tierra Energy (GTE) shares acquired by Jim Evans?

Was Jim Evans’ GTE share acquisition an open-market buy or a compensation award?

The acquisition was a compensation-related award through the Gran Tierra Inc. Employee Stock Purchase Plan. The Form 4 uses transaction code A for a grant or other acquisition and notes the transaction was exempt under Rule 16b-3, not a discretionary open-market purchase.

How are Jim Evans’ spouse’s GTE shares reported in this Form 4?
