10. Voyager Technologies Inc. (NYSE:VOYG)

Voyager Technologies surged by 29.6 percent week-on-week after its joint venture firm secured the backing of 1789 Capital to support its expansion into the low-Earth orbit (LEO) market.

In a statement on Thursday, Voyager Technologies Inc. (NYSE:VOYG) said that Starlab Space Stations, a company it jointly ventures with Airbus, Mitsubishi Corporation, MDA Space, Palantir Technologies, and Space Applications Services, secured funding support from 1789 Capital in line with the latter’s expanded investments in critical infrastructure, such as digital and orbital, among others.

“As the ISS (International Space Station) approaches retirement, we cannot afford a gap in American presence in low-Earth orbit while the Tiangong is expanding and competing for dominance in the orbital economy,” Voyager Technologies Inc. (NYSE:VOYG) President Matt Kuta said.

“Starlab is how the United States answers that challenge, not just for the commercial market, but for every national security and scientific mission that depends on assured access to LEO,” he noted.

9. RXO Inc. (NYSE:RXO)

RXO Inc. saw its share prices jump by 30.4 percent week-on-week as investors positioned portfolios after the company turned optimistic about its business, thanks to the rapid increase in truckload spot rates and better gross profits last month.

In an updated report earlier in the week, RXO Inc. (NYSE:RXO) said that its proprietary Curve truckload market forecast has shown rapidly rising truckload spot rates, excluding the impacts of fuel.

Spot rates in the first quarter of the year rose by 16.5 percent year-on-year, the highest reading since the third quarter of 2021 and markedly faster than the 5.2 percent in the fourth quarter of 2025.

As of May 15, RXO Inc. (NYSE:RXO) said that the Curve is on pace to finish the second quarter at an even higher mark, on the back of continued attrition of carrier capacity, and federal regulation enforcement, which has led to a supply imbalance relative to demand.

“We’re seeing significant linehaul and contract rate increases, despite muted shipper demand. Carriers remain under immense cost pressure, driven by increasing labor expenses, a higher cost of capital, insurance premiums, and, of course, diesel prices. The recent surge in rates, primarily due to continued capacity exits, has allowed carriers to begin to offset these inflationary pressures. If there is any uptick in shipping volumes, rates will rise at an even faster pace,” RXO Inc. (NYSE:RXO) Chief Strategy Officer Jared Weisfeld said.

Also last week, the company reported improved truckload gross profit per load in May. While still flat from April levels, the figures would finish better than the decline it projected earlier this year.

Similarly, it was able to outperform the market, with its April full-truckload volume declining by only 2 percent, as compared with the industry’s 4 percent overall dip, as measured by the Cass Freight Index.

8. Infleqtion Inc. (NYSE:INFQ)

(NYSE:INFQ) CEO Matt Kinsella said.

6. Birkenstock Holding Plc (NYSE:BIRK)

Birkenstock climbed by 32.7 percent week-on-week, after executing a $250-million accelerated share buyback program, amid the company’s belief that it remains undervalued.

In a report earlier in the week, Birkenstock Holding Plc (NYSE:BIRK) said that it entered into an accelerated share repurchase agreement with Goldman Sachs, under which the latter would initially deliver 6 million shares, or 80 percent of the total.

The final number of shares has yet to be determined, but based on the set purchase price of $33.21 apiece, Birkenstock Holding plc (NYSE:BIRK) is set to receive over 7.5 million shares from the transaction.

The listed shoemaker said that it intends to fund the buyback through a combination of cash on hand and a revolving credit facility. It expects to close the transaction before June 30, 2026.

“Short-term market dynamics have resulted in what we believe is a strong disconnect between our share price and the strength of our underlying fundamentals,” Birkenstock Holding plc (NYSE:BIRK) CEO Oliver Reichert said.

”We believe deploying our substantial cash position toward repurchasing our own shares represents the most attractive use of capital in the current environment. Given the volatile environment of the capital markets, we will continue evaluating market conditions to take advantage of further opportunities for share repurchases in the future,” he noted.

The agreement is not guaranteed and is subject to certain customary adjustments and termination provisions.
