8. TMC the metals company Inc. (NASDAQ:TMC)

In a post on X, TMC the metals company Inc. (NASDAQ:TMC) Chairman and CEO Gerard Barron said that Monday was going to “be so heavy on disclosure.”

In a statement posted on its website, TMC the metals company Inc. (NASDAQ:TMC) announced that it signed a revised sponsorship agreement with the Kingdom of Tonga for the latter’s support of its deep-sea mining activities within its jurisdiction.

Under the agreement, TMC the metals company Inc. (NASDAQ:TMC), through its subsidiary, Tonga Offshore Mining Ltd (TOML), will continue to provide existing financial benefits to the Tongan government, including training and capacity-building programs and in-country community and social programs being enjoyed by the communities to date.

In exchange, the government committed to sponsor TOML, working with the International Seabed Authority (ISA) and meeting all obligations as a sponsoring State under international law.

“For over a decade, it has been our privilege to work alongside the Government and people of the Kingdom of Tonga—one of the earliest and most committed supporters of this new industry. Tonga’s leadership has been instrumental in advocating for the responsible development of deep-sea minerals,” Barron said.

In relation to the merger, Paramount Global (NASDAQ:PARA) President and CEO Tom Ryan is stepping down from his post, as the joint company will be headed by new CEO David Ellison.

“Tariffs and a stiff currency headwind could not yet be compensated for by our mitigating price, supply chain, and cost actions in the second quarter,” he added.

1. Figma, Inc. (NYSE:FIG)

Figma fell by 27.38 percent on Monday to close at $88.6 apiece as investors resorted to profit-taking to take advantage of the two consecutive days of surge.

Figma, Inc. (NYSE:FIG) is a newly listed company, having debuted on the stock market only last Thursday.

The company initially planned to raise $1.2 billion from its initial public offering through the sale of nearly 37 million shares, comprised of 12.5 million new shares from the company and 24.5 million existing shares owned by certain shareholders.

In addition, some selling stockholders granted the underwriters a 30-day option to purchase up to an additional 5.5 million shares.

The IPO followed a terminated merger deal agreement with Adobe in 2023, under which the latter would have acquired the newly listed company for a mix of stock and cash consideration.

Although both parties believed in the merits and benefits of the merger, Adobe and Figma, Inc. (NYSE:FIG) mutually agreed to terminate the transaction based on a joint assessment that there was no clear path to receive necessary regulatory approvals from the European Commission and the UK Competition and Markets Authority.
