[기재정정]단일판매ㆍ공급계약체결(자율공시)
Capital/Financing Update Classification · 95% confidence The document is a short announcement regarding a single sales and supply contract with details about contract amount, counterpart, contract period, and changes to the contract end date. It includes no financial statements or detailed financial analysis, but rather a disclosure of a contract event. The document length is only 1282 characters, indicating it is a brief announcement rather than a full report. This fits the category of Capital/Financing Update (CAP), which covers updates on company fundraising, financing activities, or capital structure changes, including significant contracts that impact company revenue. It is not an Annual Report, Interim Report, or Earnings Release, nor is it a regulatory filing or report publication announcement. Therefore, the best classification is CAP with high confidence.
