MarkedStatusPromise
Q2'26Pendingour goal was 47% plus...That will be our primary objective to continue to stabilize a 47% plus number.
No explicit deadline was attached to this target; Q3 is guided to 47% plus or minus 100 basis points, not clearly a sustained 'plus,' and underlying ex-discrete Q2 margin did not clearly clear 47% plus on an organic basis per management's own comment. Not yet independently resolved as delivered or missed.
Q2'26Deliveredwe are positioned to support higher levels of growth into the future as we prepare to open our new supercenter facility in Malaysia this June.
Management confirmed Malaysia 'has started ramping' and 'the first revenue shipments have occurred there'.
Q2'26Deliveredestimate second quarter gross margin of 47%, plus or minus 100 basis points.
Gross margin of 47.6% was inside the 46%-48% guidance range. About 100bps came from discrete items, implying roughly 46.6% without them as an analytical estimate.
Q2'26Exceededexpect second quarter net earnings per diluted share of $2.90, plus or minus $0.30.
Actual Q2 EPS was $3.30, above the high end of the $2.60-$3.20 range.
