10-K: annual report of a US domestic issuer. Filings are the original documents hosted on SEC EDGAR — this site neither mirrors nor edits them.

FAQ

Where can I read ASSEMBLY BIOSCIENCES, INC. (ASMB) annual reports?

Every year in the table above links straight to the full text on SEC EDGAR. US annual reports are web pages (HTML) rather than PDFs, so you can read and search them in the browser without downloading anything. 3 filings are currently indexed.

What is the difference between a 10-K and a 20-F?

A 10-K is the annual report of a US domestic issuer, with sections fixed by law: Item 1 Business, Item 1A Risk Factors, Item 7 Management's Discussion and Analysis. A 20-F is filed by foreign private issuers — Taiwanese companies with US ADRs, such as TSMC, file 20-F rather than 10-K. A 40-F applies to Canadian issuers under the MJDS.

Are earnings call materials available here?

No. Earnings calls are not SEC filings, so US pages on this site cover annual reports only. Taiwan has a mandatory investor-conference disclosure regime, and those materials are indexed under Annual Reports.
