Ford Tamer, Chief Executive Officer, said, "We delivered record first quarter revenue growth, led by increased demand across all of our end markets. As we had committed, we grew non-GAAP earnings faster than revenue, achieving 86% year over year EPS growth. Our Compute and Communications business achieved record revenue, while our Industrial and Embedded business growth exceeded 20% quarter over quarter. When taken together with our strong backlog, continued design win momentum and leadership in small and mid-range FPGAs, we believe we are in the early stages of a multi-year growth cycle and are well positioned to deliver sustained, above-market growth in 2026 and beyond."

Company Overview

A global leader in its category, Lattice Semiconductor (NASDAQ: LSCC) is a semiconductor designer specializing in customer-programmable chips that enhance CPU performance for intensive tasks such as machine learning.

Revenue Growth

A company’s top-line performance can indicate its business quality. Rapid growth can signal it’s benefiting from an innovative new product or burgeoning market trend. Lattice Semiconductor struggled to generate demand over the last two years as its sales dropped by 9% annually, a rough starting point for our analysis. Semiconductors are a cyclical industry, and long-term investors should be prepared for periods of high growth followed by periods of revenue contractions.

We at StockStory place the most emphasis on long-term growth, but within semiconductors, a half-decade historical view may miss new demand cycles or industry trends like AI. Lattice Semiconductor’s performance shows it grew in the past but relinquished its gains over the last two years, as its revenue fell by 9% annually.

This quarter, Lattice Semiconductor reported magnificent year-on-year revenue growth of 42.2%, and its $170.9 million of revenue beat Wall Street’s estimates by 3.6%. Beyond the beat, we believe the company is still in the early days of an upcycle as this was the third consecutive quarter of growth - a typical upcycle tends to last 8-10 quarters. Company management is currently guiding for a 49.2% year-on-year increase in sales next quarter.

Looking further ahead, sell-side analysts expect revenue to grow 25.5% over the next 12 months, an improvement versus the last two years. This projection is commendable and suggests its newer products and services will fuel better top-line performance.

Product Demand & Outstanding Inventory

Days Inventory Outstanding (DIO) is an important metric for chipmakers, as it reflects a business’ capital intensity and the cyclical nature of semiconductor supply and demand. In a tight supply environment, inventories tend to be stable, allowing chipmakers to exert pricing power. Steadily increasing DIO can be a warning sign that demand is weak, and if inventories continue to rise, the company may have to downsize production.

This quarter, Lattice Semiconductor’s DIO came in at 151, which is 28 days below its five-year average. At the moment, these numbers show no indication of an excessive inventory buildup.

Key Takeaways from Lattice Semiconductor’s Q1 Results
