What Happened
Debra Mallonee Hart, a director of Great Southern Bancorp (GSBC), acquired 11 shares on July 14, 2026 through a dividend reinvestment (DRIP) transaction at $78.01 per share, for a total of about $858. This is an acquisition (small purchase) rather than a sale.

Key Details

• Transaction date and price: 2026-07-14 at $78.01 per share.
• Shares acquired: 11 | Total value: approximately $858.
• Transaction type: DRIP acquisition (reported as "Other acquisition or disposition (J)").
• Shares owned after transaction: not disclosed in this Form 4.
• Footnotes: F1 notes the DRIP acquisition is exempt from Section 16 reporting and was reported voluntarily. Additional footnotes (F2–F11) list various restricted‑stock vesting schedules for other awards (vesting dates range from 2019 through 2030).
• Filing timeliness: Form filed 2026-08-18 for a 2026-07-14 transaction (~35 days later). Because the filing indicates the DRIP was exempt and was reported voluntarily, the late filing is informational but may be less consequential than a late required Section 16 filing.

Context
DRIP purchases are dividend reinvestments that typically result in small, periodic share additions and are common for insiders and shareholders. Such small acquisitions are routine and do not necessarily signal a material change in insider sentiment. The filing lists multiple vesting schedules for other awards, but this particular entry is a simple reinvestment rather than an option exercise, sale, or grant.
