Today's biggest winners and losers in the stock market, a look at the notable movers:
On this episode of Stock Movers:

- Workday (WDAY) shares jumped after a Reuters report that private equity firm Silver Lake is in talks to purchase the software provider. The private equity firm has been in discussions for several months about a takeover of Workday, which makes software for business tasks such as human resources, Reuters reported Thursday citing unidentified people familiar with the talks. There is no guarantee a deal will occur, the newswire said. The shares jumped 26% to $220.50 before they were halted for volatility. Workday has been one of the software companies whose business has been threatened by artificial intelligence startups. The stock had dropped 18% through Wednesday’s close.

- Cisco Systems (CSCO) shares fell after the company projected $7.5 billion in AI data center sales this fiscal year, which disappointed investors. AI sales will make up about 10% of Cisco's projected total revenue of $72.2 billion to $73.4 billion in fiscal 2027, according to a company statement. Cisco Chief Executive Officer Chuck Robbins described the AI sales guidance as "a good, prudent guide for the year", despite analysts questioning how it lined up with AI-related orders.

- Birkenstock (BIRK) is rallying after the footwear maker boosted its adjusted Ebitda forecast for the full year. The German company also reported better-than-expected sales for the second quarter. The German company now expects revenue growth of 15% on a constant-currency basis for the fiscal year that ends in September, according to a statement Thursday, implying revenue of as much as €2.35 billion ($2.7 billion). It also sees adjusted earnings before interest, taxes, depreciation and amortization of at least €710 million. Both targets are broadly in line with analyst estimates
