In 2021, our execution resulted in year-over-year sales growth in all five reportable segments, with double-digit percentage increases in four out of the five. Throughout the year, we strengthened strategic partnerships with industry leaders, entered new product categories, and scaled operations to meet growing customer demand. We've entered 2022 with strong momentum and expect to grow core net sales to $15 billion for the full year, with profit growing even faster.
Our company is performing well in a challenging environment, leveraging our fundamental capabilities and our "More Corning" strategy to capture a compelling set of short- and long-term opportunities across our portfolio. Our scientific and manufacturing expertise and our commitment to purposeful invention put Corning at the center of major industry transformations touching almost every facet of human life.
Most importantly, we continue to build a stronger, more resilient company - one that is well positioned to continue creating value for our shareholders while supporting our customers, people, and communities for generations to come.
