Here are the companies making headlines in pre-market trading:

Nike — Shares of the sportswear giant gained 2% in pre-market activity. The rise follows a regulatory filing revealing that Apple CEO Tim Cook purchased nearly $3 million worth of Nike stock. This notable investment by a leading tech executive has bolstered investor sentiment toward the apparel leader.

Dynavax Technologies — The biopharmaceutical stock skyrocketed 38% after French healthcare giant Sanofi announced an agreement to acquire the company. The deal carries a total equity value of approximately $2.2 billion. Dynavax, known for its adult hepatitis B vaccine and a promising shingles vaccine candidate, represents a strategic biotech acquisition for Sanofi to strengthen its vaccines portfolio.

UiPath — Shares of the robotic process automation company climbed 8%. The surge follows an announcement that UiPath will be added to the S&P MidCap 400 index, a move that often triggers buying from index funds and enhances the stock's visibility among institutional investors.

Intel — The chipmaker's stock declined 3% after a Reuters report, citing sources familiar with the matter, indicated that Nvidia had recently tested manufacturing its chips using Intel's advanced 18A production process but has halted further movement on the plan. This development highlights the ongoing competitive dynamics and execution challenges within the semiconductor foundry sector.
