Positive Impact 3 of 5 earnings Written later

Calix reported unaudited fourth-quarter 2025 revenue of $272.4 million, a record that was up 32% from a year earlier and 3% from the prior quarter, and full-year 2025 revenue of $1.0 billion, up 20%. The company guided first-quarter 2026 revenue to $275 million to $281 million, above the fourth-quarter level, but its non-GAAP gross margin guidance midpoint is 75 basis points below the prior quarter.

Key points

  • Q4 2025 GAAP net income was $7.4 million, or $0.10 per diluted share; non-GAAP net income was $27.3 million, or $0.39 per diluted share.
  • Q1 2026 guidance: revenue $275 million to $281 million; non-GAAP net income per diluted share $0.34 to $0.40.
  • Non-GAAP gross margin for Q4 2025 was a record 58.0%, but Q1 2026 non-GAAP gross margin guidance midpoint is 57.25%, down 75 basis points, due to overlapping cloud costs during platform migration.
  • Calix will hold an Investor Day at the New York Stock Exchange on February 24, 2026, and a conference call is set for January 29, 2026.
