REL's last price increase was 2/2024. That was pre-tariff.
As a manufacturer I can tell you that input costs in the US have radically increased in almost every area of manufacture. Most of the prices went hyperbolic in early 2022. Most were energy input cost and transport cost (also energy sensitive) related. In the last 17 months my material prices are up more than 10% and we are not passing much of them to our customers. Because other costs are down (fuel, petroleum derivatives) our margins are not under enough pressure to raise prices and spook our customers.
I don't think their price increases were excessive, nor do I believe they are exclusively tariff related.
