Filings also show the steps taken to remove Couchbase from the public markets. A Form 25-NSE filed on September 24, 2025, by the Nasdaq Stock Market LLC provides notification of the removal of Couchbase common stock from listing and/or registration under Section 12(b) of the Securities Exchange Act of 1934. Subsequently, Couchbase filed a Form 15 on October 6, 2025, certifying the termination of registration of its common stock under Section 12(g) and the suspension of its duty to file periodic reports under Sections 13 and 15(d). The Form 15 notes an approximate number of holders of record of one as of the certification date.
