Smart Money Convergence

LAB does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.

13F data as of 2026-06-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.

Standard BioTools (ticker LAB) entered a termination agreement with Illumina on July 24, 2026, receiving about $30 million in cash in exchange for waiving certain earnout rights and terminating royalty and license agreements. Four days later, on July 28, the company agreed to sell its mass cytometry business to Multiplex Bio for $5 million, but the payment will be in the form of a promissory note (no cash upfront), with potential additional $5 million if Multiplex Bio hits a future sale threshold. Standard BioTools might also need to provide up to $10 million in working capital financing to Multiplex Bio. The deal is contingent on shareholder approval and the company's pending merger with Treeline Biosciences.
