Nasdaq Life Science Equipment Stocks Plunge 5%, $700 Million Vanishes in a Day

Bruker Corporation (NASDAQ: BRKR), a U.S. life sciences and diagnostic equipment company, showed weakness on the Nasdaq, falling 5.42% to $59.30. Its current market capitalization stands at approximately $9 billion—around 14 trillion KRW—representing a decrease in enterprise value of about $460 million (roughly 700 billion KRW) from the previous trading session. Trading volume for the day totaled 4.47 million shares.

At ASM Microbe 2026 in Washington, D.C., Bruker unveiled an expanded infection-diagnostics portfolio—including microbial identification, sepsis diagnostics, molecular testing and NGS workflows—strengthening its offerings for hospitals and research institutions.

Earlier this year, Bruker further expanded into the time-of-flight mass-spectrometry application market by acquiring the remaining stake in Swiss mass-spectrometry specialist TOFWERK, making it a wholly owned subsidiary.

Bruker is a leading U.S. scientific-instrument manufacturer, supplying mass spectrometers, NMR systems, microscopes and infection-diagnostics platforms for molecular and materials research as well as industrial and applied analysis. Its primary customers include universities, pharmaceutical companies and research institutes worldwide.

Headquartered in Billerica, Massachusetts, Bruker has broadened its presence in spatial omics and advanced life-science tools under owner-operator Frank Laukien, notably through acquisitions such as NanoString Technologies.
