Stocks were lower on Monday, though the three major indexes barely budged as traders approached the start to a busy week with caution. Trade talks, company earnings, and inflation data are all on the horizon.

These stocks made notable moves Monday:

C3.ai sank 26%. The artificial-intelligence software company pre-announced quarterly results late Friday, and guided to revenue of around $70.3 million, or roughly 33% below its previous forecast.

Shares of Monday.com cratered 30%, even after the software company posted earnings that beat expectations. Management guided for current-quarter revenue of $311 million to $313 million, possibly disappointing investors as the lower end of the range came in below estimates.

AMC Entertainment Holdings rose 3.4% after the movie-theater chain reported second-quarter earnings that beat expectations. Adjusted earnings came in at break-even per share on revenue of $1.4 billion, beating analysts’ calls for a loss of 7 cents per share on revenue of $1.3 billion.

Sarepta Therapeutics fell 1.6%. The U.S. Department of Health and Human Services confirmed the return of Food and Drug Administration regulator Dr. Vinay Prasad, just two weeks after his sudden departure. Prasad, who will resume his role as the head of the FDA’s Center for Biologics Evaluation and Research, has advocated for higher standards for drug approvals, and his exit in late July was largely seen as a good sign by biotech investors.

Albemarle shares rose 7% after battery maker Contemporary Amperex Technology said it had closed a major lithium mine in China due to licensing issues. The news drove shares of lithium producers, including Albemarle , higher amid investor speculation that Beijing could move to tackle overproduction.

Avantor jumped 5.2% after activist investor Engine Capital disclosed a 3% stake in the life-sciences company. In a statement to Barron’s, Engine Capital’s Arnaud Ajdler and Brad Favreau called for stricter cost discipline, immediate share repurchases, and “a significant overhaul of the Board,” among other changes. Avantor didn’t respond to a request for comment.

Tegna stock jumped 30% on multiple reports suggesting the TV station operator was in talks to be acquired by larger rival Nexstar Media Group. Reports of a possible deal come as the Federal Communications Commission embarks on a deregulation push that could see the broadcasting industry narrowed to fewer competitors. Nexstar shares rose 3.9%.

Rumble was up 3.1% after rising double-digits earlier in the session. The video-sharing platform unveiled an all-stock bid to buy German data-infrastructure company Northern Data Group for roughly $1.2 billion. Stablecoin issuer Tether, Northern Data’s largest shareholder, has indicated its support. Completion of the offer would make Tether the single largest holder of Rumble common stock.

Coinbase Global rose 2.9%, mirroring a jump in crypto prices over the weekend. Bitcoin was up 0.4% to $188,767 over the past 24 hours, according to CoinDesk data, hovering below its record high of nearly $123,000. Shares of Coinbase, the largest cryptocurrency exchange in the U.S. by trading volume, often rise and fall along with crypto sentiment.

MicroStrategy shares rose 1.3%, likely boosted by the surge in crypto prices. The world’s largest corporate holder of Bitcoin reported its latest purchase of 155 tokens for an average of $116,401 each, bringing its total holdings to 628,946 Bitcoins as of Aug. 10.

Shares of Nvidia was down 0.4% while Advanced Micro Devices shares declined 0.3%. The Wall Street Journal reported Sunday that the chip makers plan to give the Trump administration a 15% cut of the revenue generated by sales of their AI chips in China. The arrangement comes alongside approval for exports of Nvidia’s H20 AI chip and AMD’s MI308 to China, the Journal reported, citing people familiar with the matter.

Earnings reports are expected this week from BigBear.ai, Oklo, Circle, On Holding, Cardinal Health, Cava, Lumentum, CoreWeave, H&R Block, Rigetti Computing, Coherent, Cisco Systems, Advance Auto Parts, Deere, JD.com, NetEase, Tapestry, and Applied Materials.
