Coupang, Inc. 8-K/A

What Happened
Coupang, Inc. filed an 8‑K/A on December 29, 2025 updating a cybersecurity incident previously disclosed on December 16, 2025. Coupang Corp. (its Korean subsidiary) issued updates on December 24 and December 28, 2025 stating the perpetrator has been identified, is cooperating, and turned over the devices used. The investigation indicates roughly 33 million accounts were accessed, but the perpetrator only saved limited data from about 3,000 customer accounts; that saved data has been deleted and not shared with any third party. Coupang also announced a customer compensation program of approximately ₩1.685 trillion (≈ $1.2 billion) in vouchers starting January 15, 2026.

Key Details

• Date of updates: December 24 and December 28, 2025 (PST); 8‑K/A filed December 29, 2025.
• Accounts impacted: ~33 million accounts accessed; limited data saved from ~3,000 accounts and deleted.
• Customer compensation: ₩1.685 trillion (~$1.2B) in vouchers to affected customers, usable on future Coupang purchases beginning Jan 15, 2026.
• Accounting effect: Vouchers will be recorded as reductions to selling price and revenue recognized on the related transactions. Investigation is ongoing; copies of the updates were furnished as Exhibit 99.1.

Why It Matters
This is a material cybersecurity disclosure that can affect revenue recognition and customer trust. The voucher program is large (≈ $1.2B) and will reduce reported revenue on future transactions where vouchers are used, so investors should watch for how Coupang records and quantifies the financial impact in upcoming filings. Ongoing investigation updates and any regulatory or legal developments could further affect operations, costs, or future disclosures.
