Biggest stock movers Monday: REPL, BKR, and more

[Stock market chart]
Stock futures fell Monday morning as investors reacted to a breakdown in peace talks between the U.S. and Iran over the weekend. Tensions spiked after President Donald Trump threatened a military blockade of the Strait of Hormuz, a move that quickly pushed oil prices back above the $100-a-barrel mark.

Here are some of Monday's biggest stock movers:

BIGGEST STOCK GAINERS

* BAKER HUGHES (BKR [https://seekingalpha.com/symbol/BKR]) +2% - Shares rose after agreeing to sell its Waygate Technologies unit to Hexagon AB for ~$1.45B in cash as part of a broader effort to streamline its portfolio and enhance earnings stability and cash flow. The divestiture includes key inspection and imaging technologies and aligns with ongoing strategic actions, including prior asset sales and the pending acquisition of Chart Industries, with the deal expected to close in H2 2026.

BIGGEST STOCK LOSERS

* REPLIMUNE GROUP (REPL [https://seekingalpha.com/symbol/REPL]) -60% - Shares plunged after the U.S. Food and Drug Administration issued a Complete Response Letter declining approval of its lead asset, RP1, for advanced melanoma in combination with nivolumab, marketed by Bristol Myers Squibb as Opdivo. The setback raises significant concerns over the company’s pipeline and regulatory outlook, triggering a sharp selloff following a trading halt.
* CHILDREN’S PLACE (PLCE [https://seekingalpha.com/symbol/PLCE]) -16% - Shares tumbled after a weak Q4 marked by a sharp earnings and revenue miss, with sales down 19.4% Y/Y to $329M and comparable sales falling 10.7%, driven by weaker e-commerce traffic, reduced Amazon shipments, and soft consumer demand. Profitability deteriorated significantly as gross margin contracted 500 bps to 23.5% due to tariffs, markdowns, and higher inventory reserves, while operating results swung to a loss, underscoring ongoing execution challenges despite improved cash flow and inventory reduction efforts.
