Andrew Brackmann has given his Buy rating due to a combination of factors, starting with Quest’s first-quarter performance coming in ahead of Wall Street expectations on both revenue and earnings. He notes that organic test volume has accelerated for four consecutive quarters, signaling healthy underlying demand and suggesting that structural advantages for large national laboratories remain intact.
Brackmann also highlights that management raised full-year revenue guidance roughly in line with the quarterly beat, reinforcing confidence in earnings visibility and growth durability. While shares trade at a valuation above their long-term average, he believes the premium is warranted given Quest’s solid top-line drivers, defensive business profile, and improving volume trends that helped offset earlier weather-related disruptions.
