BioAtla shares fall 24.12% after-hours after Nasdaq delisting notice over bid price and equity failures.

BioAtla Inc. (NASDAQ:BCAB) fell 24.12% in after-hours trading following Nasdaq’s decision to delist the company for failing to meet the $1.00 bid price rule and insufficient $2.5 million in stockholders’ equity. The delisting, effective February 10, 2026 unless stayed, triggers an appeal to the Nasdaq Listing Council. The move to over-the-counter (OTC) trading under the ticker BCAB is expected if suspended, likely reducing liquidity and investor confidence. This regulatory action overshadowed earlier news from December 31, 2025, regarding a share issuance and delayed reverse split, as the immediate delisting threat dominated market sentiment. The sharp decline reflects investor concerns over the company’s compliance status and potential market fragmentation.
