On Monday alone, Celestica Inc.

3. Rambus Inc. (NASDAQ:RMBS)

Rambus dropped for a second day on Tuesday, slashing 21.17 percent to close at $111.27 apiece, as investors took path from an investment firm’s rating downgrade amid the ongoing shortage of memory products.

In a market note, Baird downgraded its rating for Rambus Inc. (NASDAQ:RMBS) to neutral from outperform previously, amid an expected slowdown in Registered Dual Inline Memory Module or RDIMM.

“While the acceleration in x86 demand, notably driven by agentic AI, is positive for Rambus, we are increasingly seeing the potential for a slowdown in RDIMM [year-on-year] growth next year due to increasing DRAM shortages, which we expect will persist throughout 2027,” Baird said.

“Rambus is the classic case of a unit-driven top-line impacted at times of severe memory shortages without the benefit of higher pricing,” it noted.

On Monday, Rambus Inc. (NASDAQ:RMBS) reported a net income of $59.9 million in the first quarter of the year, flat from the $60.3 million in the same period last year. Total revenues, however, grew by 8 percent to $180.2 million from $166.7 million year-on-year.

“Rambus opened 2026 with a solid first quarter, delivering financial results in line with guidance and generating strong cash from operations,” Rambus Inc. (NASDAQ:RMBS) President and CEO Luc Seraphin said.

“The growth of AI inference and agentic workloads in the data center continues to drive demand for higher memory bandwidth, efficient data movement, and scalable connectivity. With expanding offerings across chips and IP, Rambus is well positioned to support next-generation AI platforms and drive profitable long-term growth,” he noted.

2. Erasca Inc. (NASDAQ:ERAS)

Erasca Inc. plunged by 48.30 percent on Tuesday to close at $9.90 apiece, as investors sold off positions following the death of a patient enrolled in the first phase of clinical trial testing the efficacy of its pancreatic and lung cancer treatment candidate, ERAS-0015.

In a call with analysts, Erasca Inc. (NASDAQ:ERAS) confirmed the death of a 66-year-old man who developed Grade 3 pneumonitis on 24 mg. He was said to have elected to withdraw supportive care, which later resulted in his death. Management deemed the case a “rare event.”

Despite the case, Erasca Inc. (NASDAQ:ERAS) maintained ERAS-0015 as potentially the best-in-class amid positive preliminary data from the first phase across all other enrolled patients.

According to the company, ERAS-0015 demonstrated favorable response rates, with more than half of enrolled lung cancer patients seeing their tumors shrink, and around 50 percent of pancreatic cancer patients saw shrinkage.

ERAS-0015 also demonstrated a favorable safety profile and recorded only low-grade adverse events.

“We are thrilled with the robust efficacy results demonstrated so far by our pan-RAS inhibitor ERAS-0015 in patients with lung and pancreatic cancer. The magnitude of clinical benefit seen during dose escalation is particularly striking and compares favorably with other pan-RAS, pan-KRAS, or KRAS-mutant selective inhibitors,” said Erasca Inc. (NASDAQ:ERAS) Chairman and CEO Jonathan Lim.

“Notably, preliminary data support ERAS-0015 may be combined with standard-of-care doses of panitumumab, positioning it as a potential backbone therapy for future combination regimens. Together, we believe these findings support the best-in-class potential of ERAS-0015, and we look forward to continued progress in our Phase 1 monotherapy dose expansion cohorts and combination dose escalation cohorts,” he noted.
