Stocks reacted to various developments on Thursday, July 10, 2025. Kellogg's stock, WK Kellogg, surged 3.49% to $17.50 following reports that Italian chocolate maker Ferrero is nearing a deal to acquire the breakfast food company for about $3 billion [1]. The acquisition could close as early as this week, according to The Wall Street Journal. Ferrero's offer represents a 31% premium over WK Kellogg's current share price.

Meanwhile, NVIDIA's shares rose 1.80% to $162.88 after OpenAI reaffirmed its preference for NVIDIA GPUs, boosting investor confidence in the company's AI compute leadership [3]. NVIDIA's market capitalization surpassed $4 trillion, making it the largest public company globally.

Costco's shares dipped 0.38% to $982.09 despite an 8% year-over-year increase in net sales for June, reaching $26.44 billion. The company reported a 8% increase in net sales for the first 44 weeks of the year, totaling $227.46 billion [4]. The decline in Costco's stock price may be attributed to ongoing inflation and supply chain challenges.

Plug Power's stock surged 25.35% to $1.78 after announcing a renewal of its hydrogen supply agreement, signaling continued growth in the clean energy sector [5]. The agreement renewal strengthens Plug Power's position as a leading provider of hydrogen fuel cell turnkey solutions.
