Sierra Wireless (NASDAQ: SWIR) has failed to live up to its massive potential, as its largest business -- original equipment manufacturer (OEM) solutions -- has hit a brick wall. The story was no different when it released its fiscal first-quarter results in early May. The Internet of Things (IoT) specialist saw a tepid annual increase of just 2% in OEM solutions revenue, while gross margin in the segment fell nearly 3 percentage points.But Sierra investors were a satisfied lot as the company showed that it has found new catalysts to offset the weakness in OEM solutions.
