Continued weakness in the automotive and industrial segments acted as a headwind, but the company sees conditions improving a bit going forward.

What management had to say

Littelfuse CEO Dave Heinzmann discussed the good and the bad in the first quarter:

We're off to a strong start to 2017, with sales and adjusted earnings per share at the high end of our guidance range. We saw strong order rates continue through the first quarter in our electronics segment. Our automotive sales growth was negatively impacted by planned sensor product exits and challenging prior year comparisons from related last-time buys, as well as higher customer inventories. We were encouraged by sequential sales growth in both our commercial vehicle business and industrial segment, as end market weakness moderated.

Heinzmann also added some detail to the company's second-quarter guidance: "Our positive momentum has carried into the second quarter as we continue to see strong order rates across our electronics segment. With more stable trends in some heavy industrial markets, we expect stronger revenue growth to drive margin expansion for the second quarter."

Looking forward

The electronics segment continues to be the strongest performer on an adjusted basis, more than offsetting tepid sales in the automotive and industrial segments. The company does see weakness in those two segments moderating going forward, but the electronics business looks like it will be the main growth driver for the time being.

Littelfuse expects double-digit revenue growth during the second quarter, along with a significant increase in adjusted EPS. The company reported adjusted EPS of $1.44 during the second quarter of last year.
