Diamond Hill Mid Cap Strategy stated the following regarding Teledyne Technologies Incorporated (NYSE:TDY) in its Q4 2024 investor letter:

"As valuations have continued rising and the economic cycle has gotten relatively long in the tooth, we’ve thought carefully about where and how we are exposed to more cyclical stocks. As such, we initiated a number of new positions in Q4, including ICON, Informatica, Teledyne Technologies Incorporated (NYSE:TDY), LPL Financial Holdings, Teleflex Incorporated and Solventum Corporation.

Teledyne Technologies is a diversified industrial technology provider focused on specialty sensors and instrumentation products. The company has a long history of creating shareholder value via margin improvement and M&A activity. However, some lingering investor skepticism around Teledyne’s acquisition of FLIR Systems, its largest and priciest acquisition to date, has weighed on the valuation some, making it attractive relative to its high-quality industrials peers. Though the acquisition has taken longer than some anticipated to generate synergies, we believe this is partly attributable to near-term macroeconomic related weakness and find the FLIR deal a successful one. Given our confidence in the long-term outlook for Teledyne, we capitalized on the attractive valuation to initiate a position."
