115年4月背書保證與資金貸與
Regulatory Filings Classification · 85% confidence The document is a regulatory disclosure of the company’s loans to others and endorsements/guarantees for the month of April (ROC Year 115). It does not present a full financial report (Annual or Interim), earnings release, or board changes. Instead, it provides mandatory monthly compliance data under the market observation system.

115年4月營業收入
Regulatory Filings Classification · 87% confidence The document is a monthly consolidated revenue summary filed on Taiwan’s Market Observation Post System (MOPS). It provides net operating revenue figures for April and year-to-date, with explanatory footnotes on IFRS adoption, but contains no full financial statements or management analysis typical of an interim/quarterly (IR) or annual report (10-K). It is essentially a mandatory regulatory submission of monthly revenue data, fitting the fallback category for miscellaneous regulatory disclosures. Therefore, it is classified as a Regulatory Filing.

Report Publication Announcement Classification · 90% confidence The document is a brief announcement from a listed company via the public information observatory that the 115-year first quarter consolidated financial report is expected to be submitted to the board of directors on a specified date. It contains no actual financial data or analysis—only the timing of the board meeting and report submission. Under the “menu vs meal” rule, this is an announcement about the timing/publication of a report rather than the report itself, matching the definition of a Report Publication Announcement (RPA).
