What comes next for SPS Commerce?

For the first quarter, SPS is guiding for sales of $145.9 million to $146.7 million. Meanwhile, adjusted earnings per share are projected to be between $0.72 and $0.73.

For the full year, management is targeting sales between $616.5 million and $619 million, which would equal growth of 15% at the midpoint of the guidance range.

SPS stock is now up roughly 56% over the past year, and it is valued at roughly 12.7 times average sales expectations and 67.7 times average earnings expectations for 2024. That's a heavily growth-dependent valuation -- particularly in light of management's earnings growth target for the year. On the other hand, SPS appears to have a foundation in place that will help it capitalize on much larger long-term opportunities in the expanding supply chain software industry.
