Illumina, Inc. announced its financial results for the first quarter of fiscal year 2025 on May 8, 2025. The company reported Core Illumina revenue of $1.041 billion, a 3.3% decline year-over-year, but this figure topped Wall Street's expectations. Non-GAAP diluted EPS was $0.97, also beating consensus estimates. Despite the EPS beat, Illumina lowered its full-year 2025 guidance, now expecting Core Illumina constant currency revenue to decline in the range of 0.5% to 2.5%, translating to reported revenue between $4.23 billion and $4.31 billion. This adjustment primarily reflects the impact of new tariffs on its business, particularly affecting operations in China. The company's non-GAAP operating margin is now projected to be approximately 22% to 22.5%, with non-GAAP diluted EPS expected in the range of $4.45 to $4.55. Positively, the U.S. Securities and Exchange Commission (SEC) concluded its investigation into Illumina's acquisition of GRAIL on May 9, 2025, removing a significant regulatory overhang for the company.
