10. Coupang Inc. (NYSE:CPNG)

Coupang saw its share prices jump by 5.25 percent on Tuesday to close at $18.03 apiece, as investors traded while awaiting updates on its appeal in relation to a $410 million penalty imposed by South Korea’s Personal Information Protection Commission over a data breach.

In a comment last week, Coupang Inc. (NYSE:CPNG) hinted at appealing the commission’s decision, while committing to strengthening its data protection system.

“We regret that our proactive measures to prevent secondary harm from last year’s data leak incident, as well as our explanations based on clear facts, were not sufficiently reflected in the PIPC’s decision,” it said.

“We expect that the facts will be clearly established through legal procedures,” it noted.

PIPC’s penalty marked as the largest imposed penalty against a company so far, exceeding penalties for data breach slapped against SK Telecom and KT previously.

“This incident was caused not by sophisticated hacking techniques, but by Coupang’s inadequate basic security management system and negligence,” PIPC Chairwoman Kyung Hee Song was quoted as saying in an online briefing on the decision.

It is believed that the data breach had occurred as early as June last year, but was only uncovered five months later.

Coupang Inc. (NYSE:CPNG), often referred to as the Amazon of South Korea, is the largest e-commerce operation in the said republic, holding over a third of the country’s e-commerce market share.

9. Keel Infrastructure Corp. (NASDAQ:KEEL)

Keel Infrastructure grew its share prices for a fourth consecutive day on Tuesday,  adding 5.30 percent to close at $5.96 apiece, as investors placed bets on its stock amid renewed optimism for the AI sector.

At intra-day trading, Keel Infrastructure Corp. (NASDAQ:KEEL) traded just 28 cents shy of its 52-week high of $60.60, mirroring the rally among its counterparts, thanks to the rapid growth of the artificial intelligence sector.

The rally followed last week’s news that it successfully raised $458 million in fresh funds from convertible senior notes carrying a yield rate of 1.250 percent through 2032.

Interest rates will be paid semi-annually every 15th of January and July of the year, beginning January 15, 2027, until it matures in 2032.

The notes are convertible to $7.41 per share, which represents an approximately 25 percent premium over the $5.93 closing price on June 4, 2026.

Keel Infrastructure Corp. (NASDAQ:KEEL) said that proceeds from the offer will be used to make value-added investments across its current developments, general corporate purposes, which may include funding deposits for long-lead equipment and/or collateralizing letters of credit related to expanding and/or accelerating data center development projects.

8. Fermi Inc. (NASDAQ:FRMI)

Fermi rallied for a fifth straight session on Tuesday, jumping 5.35 percent to finish at $7.88 apiece, as investors resumed buying positions amid ongoing buzz that OpenAI was planning to lease its Project Matador campus.

Last week, JMP Citizens reported that OpenAI could be among the companies assessing Fermi Inc.’s (NASDAQ:FRMI) capacity at the Project Matador, with the two firms already nearing an agreement.

Fermi Inc. (NASDAQ:FRMI) earlier said that it was on track to deliver approximately 1.1 gigawatts of new power at its Amarillo campus by the end of the year. The entire project is designed to deliver 17 GW of energy by 2030.

Last month, it also hinted at securing a leasing agreement with a new tenant over the next three months, details of which have not been divulged.

In other news, Fermi Inc. (NASDAQ:FRMI) said that it mailed a consent revocation statement to its shareholders enclosing a white consent revocation card in response to the consent solicitation by former CEO Toby Neugebauer seeking to call a special shareholders meeting.

“Fermi is building on its entrepreneurial foundation and scaling the business to support long-term growth and execution. The Company is seeing real results across the business and achieving major construction, regulatory, and financing milestones. Despite this meaningful momentum, Fermi’s former CEO, Toby Neugebauer, is soliciting support to obtain the authority to call a Special Meeting in the hopes of filling the Fermi Board of Directors with his own hand-picked nominees to advance his personal agenda at your expense,” it said.

7. Moderna Inc. (NASDAQ:MRNA)

Moderna extended its winning streak to a fourth consecutive day on Tuesday, surging 6.27 percent to close at $55.40 apiece, as investors cheered the looming launch of three new vaccines over the next two years.

In a statement on the same day, Moderna Inc. (NASDAQ:MRNA) said that it is planning to launch the flu plus COVID, seasonal flu, and norovirus vaccines between 2027 and 2028.

At the same time, it is expecting important clinical milestones this year, including potential pivotal data readouts for its investigational individualized neoantigen therapy (Intismeran autogene) and a therapeutic for the rare genetic disease propionic acidemia, which could support the possible launch of its first oncology and rare disease products.

In other news, Moderna Inc. (NASDAQ:MRNA) appointed Ester Banque as its new chief commercial officer, effective on Monday, June 15. She is tasked to focus on continuing to build out the company’s global commercial organization, leading execution across product launches, and expanding presence in new markets.

6. Eos Energy Enterprises Inc. (NASDAQ:EOSE)

Eos Energy rallied for a second day on Tuesday, climbing 6.74 percent to close at $6.81 apiece, as investors cheered the official start of production at its new facility in Pennsylvania.

In an updated report, Eos Energy Enterprises Inc. (NASDAQ:EOSE) said that its Thorn Hill manufacturing facility in Marshall Township is now in full operation following the successful completion of Site Acceptance Testing for Battery Line 2.

The second unit supports the company’s goal of achieving 4 GWh of annual manufacturing capacity by the end of the year.

Eos Energy Enterprises Inc. (NASDAQ:EOSE) said that demand for its technology continues to build across multiple applications, partly supported by Frontier Power USA’s (FPUSA) 2 GWh capacity reservation agreement.

Last month, FPUSA signed its first transaction to acquire a 480 MWh battery project portfolio in Texas from Bimergen Energy, followed by FPUSA’s strategic framework agreement with Stella Energy Solutions to further advance a 2 GWh pipeline built around Eos technology.

“Battery Line 2 demonstrates our ability to continuously improve as we scale,” Eos Energy Enterprises Inc. (NASDAQ:EOSE) Chief Operating Officer John Mahaz said.

“We took the lessons learned from commissioning and operating Line 1 and incorporated them directly into the design of this facility and production line. The result is a more efficient manufacturing environment with better flow and a stronger foundation for future expansion. Most importantly, it validates that our manufacturing system can be replicated and scaled with discipline,” he noted.
