Research Alert: CFRA Lowers View On Bio-rad Laboratories To Sell From Hold
CFRA, an independent research provider, has providedwith the following research alert. Analysts at CFRA have summarized their opinion as follows:We lower our 12-month price target by $45 to $235, reflecting a 25.6x multiple of our 2026 EPS estimate (down to $9.17 from $10.15; we cut our 2027 EPS estimate to $9.97 from $10.68), a discount to BIO's three-year historical forward average of 29.5x. Rather than a dramatic cut to National Institutes of Health (NIH) funding, Congress approved a modest increase for 2026 funding, helping reduce research budget concerns that loomed during 2025. However, BIO and peers anticipate that research spending growth from academic and early-stage biotech could remain muted over the near term as academic institutions adjust. The outlook for 2026 anticipates ongoing pressure, with BIO cutting sales and margin expectations during the Q1 earnings report, citing headwinds arising from the U.S.-Iran conflict in the Middle East such as weaker diagnostics sales and higher freight and fuel costs.
