5. Insmed Incorporated (NASDAQ:INSM)

Insmed climbed by 11.66 percent on Tuesday to close at $116 apiece, as investors resorted to bargain-hunting after touching a 10-month low the day prior.

On Monday, it can be recalled that the stock fell below the $100 territory, touching $98.90 at intra-day trading—its lowest price over the last 10 months, dented by an earnings miss in the first quarter of the year.

In the first quarter of the year, Insmed Incorporated (NASDAQ:INSM) slashed its net loss by 36 percent to $163 million from $256 million in the same period last year, as total revenues soared by 230 percent to $306 million from $92.8 million year-on-year, thanks to strong sales from its lung treatment, Brinsupri.

The therapy alone raked in $207.2 million in sales in the US, and $700,000 internationally.

“The trajectory of the Brinsupri launch continues to exceed our expectations, and we are especially encouraged by the positive topline results from the Encore Phase 3b study, which could enable us to extend our reach to even more patients. We remain focused on improving bronchiectasis diagnosis, expanding the Arikayce label, advancing our Phase 3 programs for TPIP, and progressing our early-stage pipeline, with the ambition of delivering meaningful innovation and improving the lives of patients with serious diseases,” said Insmed Incorporated (NASDAQ:INSM) CEO Will Lewis.

In other news, the company is set to present data from the Phase 3b study for Arikayce at the American Thoracic Society International Conference 2026 on May 17 to 20.

Venture Global rallied for a second day on Tuesday, surging 14.20 percent to close at $13.27 apiece, as investors cheered a double-digit growth in both net income and revenues for the first quarter of the year, while markedly raising its growth outlook for 2026.

In a statement, Venture Global Inc. (NYSE:VG) said that it grew its net income by 23 percent to $488 million from $396 million in the same period last year, primarily driven by higher operating income of $71 million, thanks to higher LNG sales volume from the Plaquemines site.

Revenues climbed 59 percent to $4.599 billion from $2.894 billion year-on-year.

“The first quarter of 2026 was a dynamic, and at times volatile period for the global LNG market, and we are proud that our company has played a critical role in helping maintain supply stability. Venture Global continues to deliver reliable US energy to our customers, while generating strong financial results for our shareholders,” Venture Global Inc. (NYSE:VG) CEO Mike Sabel said.

We are continuing the safe startup and commissioning of Plaquemines LNG and are reaffirming our expectation of achieving Phase I commercial operations later this year.

2. Quantum Computing Inc. (NASDAQ:QUBT)

Quantum Computing climbed by 15.72 percent on Tuesday to finish at $11.78 apiece, as investor sentiment was boosted by the 9,364 percent jump in its revenues in the first quarter of the year, thanks to the share of newly acquired companies.

In an updated report, Quantum Computing Inc. (NASDAQ:QUBT) said that it incurred $3.69 million in revenues during the period, a marked jump from only $39,000 in the same period last year, driven primarily by its acquisition of Luminar Semiconductor Inc., and to a lesser extent, NuCrypt LLC.

On the other hand, Quantum Computing Inc. (NASDAQ:QUBT) swung to a net loss of $4.05 million from a $16.98 million net income in the same comparable period, primarily due to higher operating expenses, coupled with the decrease in non-cash gain on the mark-to-market of the company’s derivative liability, which relates to warrants issued for the merger with Qphoton in June 2022.

Looking ahead, the photonics firm posted an upbeat outlook for its business amid expected demand growth to support faster and more efficient data processing.

“It is becoming increasingly clear that photonics will be a critical component of future technological advancements given its low power consumption and ability to operate at room temperature. During the first quarter we strengthened our position in this space, and made significant progress in advancing our technology roadmap and continued to grow our commercial momentum,” Quantum Computing Inc. (NASDAQ:QUBT) CEO Yuping Huang said.
