Rhea-AI Filing Summary

SunOpta Inc. CFO Greg Gaba exercised 9,611 Restricted Stock Units into an equal number of Common Shares on April 11, 2026. Each Restricted Stock Unit represents a right to receive one SunOpta common share.

Insights

Equity compensation analyst

Routine RSU vesting with tax withholding; neutral signal.

CFO Greg Gaba converted 9,611 Restricted Stock Units into Common Shares and settled related taxes via 4,390 shares withheld at $6.48. This is a standard equity-compensation event rather than an open-market trade.

After the transactions, he directly holds 127,908 Common Shares and 19,221 Restricted Stock Units, indicating he maintains a meaningful equity stake. Because the disposition is solely for tax withholding and not a discretionary sale, the filing provides limited insight into his view of SunOpta’s valuation.

Restricted Stock Units financial

"Each Restricted Stock Unit represents a contingent right to receive one share of STKL common stock."

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

tax-withholding disposition financial

"This line item reflects the deemed disposition of shares withheld by the Company to satisfy income tax withholding requirements"

A tax-withholding disposition is an event or transaction—such as selling or transferring securities, exercising options, or receiving compensation—that triggers a requirement to hold back part of the payment and remit it to tax authorities. It matters to investors because it reduces the cash they receive immediately and can change the timing and amount of taxable income, like a cashier taking a portion of your sale proceeds to pay taxes before you get the rest.

derivative security financial

"transaction_code_description": "Exercise or conversion of derivative security""

A derivative security is a financial contract whose value comes from the price or performance of something else, such as a stock, bond, commodity, or market index. For investors it acts like an insurance policy or a wager: it can be used to protect against losses, lock in prices, or amplify gains and losses, so it can change a portfolio’s risk and potential return without owning the underlying asset directly.

vesting financial

"in connection with the vesting of the RSUs."

Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.

contingent right financial

"represents a contingent right to receive one share of STKL common stock."
