Power Solutions International (PSIX) reported late Monday lower-than-expected adjusted EPS and revenue in Q1.

Shares sank 40% following a surge in intraday trading volume to over 4.0 million from a daily average of about 675,000.

ZoomInfo Technologies (GTM) shares fell about 33% following its Q1 results in the previous day that led some analysts, including from Stifel and Piper Sandler, to downgrade the stock.

The firm faces execution risk in delivering a material re-acceleration in top-line growth amid job cuts, and a downward revision to its full-year 2026 sales guidance is discouraging, RBC Capital Markets said in a note.

Trading volume jumped to more than 24.6 million shares intra-day from a daily average of about 10.1 million.

Piper Sandler downgraded LENZ Therapeutics (LENZ) to neutral from overweight and cut its price target to $12 from $39, following the company's Q1 results late Monday that showed net loss more than doubled from a year ago.

Shares dropped about 24%, with intraday trading volume of over 1.6 million, versus a daily average of about 910,000.
