ADTRAN Holdings reports preliminary Q2 2026 results

ADTRAN Holdings announced preliminary, unaudited revenue, preliminary GAAP and non-GAAP operating margin, and preliminary GAAP and non-GAAP basic and diluted earnings per share for the fiscal quarter ended June 30, 2026, officials said. Reaction in equities markets was pending at the time of the announcement.

Preliminary second-quarter details

Officials said the notice provided a topline preview rather than final figures: the company described revenue, margins and EPS as preliminary and unaudited. The statement was issued on July 22, 2026, and was provided to meet German ad hoc disclosure rules tied to the company’s performance relative to prior guidance, officials said.

Officials did not publish exact dollar or per-share numbers in the preliminary release. The company noted GAAP and non-GAAP measures would be reported; officials cautioned the figures remain subject to closing adjustments and audit review.

Investors should expect the company’s full second-quarter disclosures to appear in its formal filings. Under standard SEC filing timelines, non-accelerated filers may have up to 45 days after quarter end to file quarterly reports; that 45-day window ends on August 14, 2026, which is the latest practical date to watch for the company’s complete 10-Q filing and audited quarter figures.
