Adtran Holdings Announces Preliminary Q2 2026 Financial Results Below Expectations

Adtran Holdings, Inc. has announced that its preliminary financial results for the second quarter of 2026 indicate revenue and non-GAAP operating margin falling below its previous guidance range. Revenue is estimated between $280.0 million and $282.0 million, shy of the projected $283.0 million to $303.0 million. Additionally, the non-GAAP operating margin is expected to be between 3.5% and 4.0%, underperforming the 5.0% to 9.0% guidance.

The company's estimated non-GAAP earnings per share range from $0.03 to $0.05, which is below the analyst consensus of $0.13. Factors contributing to these deviations include project timing from a customer and higher component and freight costs.

The company notes that these preliminary results are based on unaudited figures and subject to final financial procedures. The final quarterly results will be published after the market closes on August 3, 2026, or before the market opens on August 4, 2026.
