CFRA, an independent research provider, has providedwith the following research alert. Analysts at CFRA have summarized their opinion as follows:PCAR's Q1 results matched consensus with operating EPS of $1.15 vs. $0.96 in the prior year, supported by the absence of litigation charges that impacted Q1 2025. New truck deliveries fell 7K units to 33.1K globally, with North American Class-8 shipments declining while Europe showed strength. The Parts business managed positive expansion despite truck sales softness, benefiting from strategic investments in distribution infrastructure. Management maintained an upbeat tone on customer demand trends, though their North American outlook for retail Class-8 truck sales remained unchanged from Q4. PCAR generated healthy operating cash flow of $972M vs. $910M and maintained a strong balance sheet, in our view. Management projected full-year capex of ~$750M and R&D expenses of ~$475M for next-generation powertrains. We see the unchanged shipment projections as a signal that management is not entirely confident an inflection is occurring stronger than previously anticipated.
Erasca (ERAS) shares fell 48% Tuesday after the company reported preliminary phase 1 dose-escalation data for its experimental ERAS-0015 in patients with RAS-mutant solid tumors, including colorectal cancer, non-small-cell lung cancer and pancreatic adenocarcinoma.The preliminary data, from ongoing trials in the US and China, suggest ERAS-0015 may be combined with standard-of-care doses of panitumumab, positioning it as a potential backbone therapy for future combination regimens, the company said.The therapy was generally "well tolerated," with no dose-limiting toxicities or treatment discontinuations due to adverse events, according to a statement.Erasca said it selected 24 mg and 32 mg once daily as recommended doses for further study and said the drug showed "promising clinical potential" for combination use with panitumumab.In a regulatory filing, the company said a patient, who was a 66 year-old male with heavily pretreated metastatic pancreatic adenocarcinoma, had died. The company said grade 3 treatment-related adverse events of pneumonitis progressed to grade 5 following withdrawal of supportive care per patient decision.Price: $9.96, Change: $-9.20, Percent Change: -48.02%
