FY2026
ADTRAN Holdings generated first-half fiscal 2026 revenue of $567.2 million, with Q1 growing 15.5% year-over-year to $286.1 million and Q2 growing 6.1% year-over-year to $281.1 million, both periods supported by broadband expansion and ongoing vendor consolidation activity 34 37. Q1 returned to GAAP operating profitability at 2.2% of revenue compared to a -1.6% operating loss in Q1 2025, while Q2 GAAP operating margin remained negative at -3.6% and non-GAAP operating margin reached 3.8%, below prior guidance of 5.0%-9.0%, driven by a single customer project delay and elevated component and freight costs 34 36 38. Optical Networking Solutions contributed materially in both quarters, supported by high-risk vendor displacement in Europe, while U.S. revenue grew 41.6% in Q1 and 11.7% in Q2 year-over-year 34 37. During the period the company issued $201.3 million of convertible senior notes and entered into a new $350.0 million credit facility with JPMorgan Chase Bank maturing July 2031, with net debt increasing from $105.2 million at end of Q1 to $114.6 million at end of Q2 37 138. The company introduced the LiteWave800 product targeting intra-data center AI infrastructure and reported BEAD deployment funds beginning to reach operators in a growing number of U.S. states 35.
FY2025
ADTRAN Holdings reported full-year 2025 revenue of $1,083.8 million, a 17.4% increase from $922.7 million in 2024, driven by normalized customer spending, fiber expansion, vendor consolidation, and growing demand for infrastructure modernization 32, 33. Revenue expanded each quarter from $247.7 million in Q1 to $291.6 million in Q4, while the full-year GAAP operating loss was $15.6 million and adjusted operating income reached $51.7 million 133. Gross profit margin expanded to 38.3% from 35.1% in 2024, supported by the completion of the Business Efficiency Program at the end of 2024 32. Full-year operating cash flow was $129.8 million and free cash flow $98.0 million; in September 2025 the company issued $201.3 million of 3.75% convertible senior notes due 2030, using proceeds to repay revolving credit borrowings and ending the year with $95.7 million in cash and net debt of $97.3 million 32, 133, 135. Material weaknesses in internal control over financial reporting, arising from restatements in 2023, 2024, and 2025, remained unremediated as of December 31, 2025 32.
FY2024
ADTRAN Holdings reported full-year 2024 revenue of $922.7 million, down 19.7% from $1,149.1 million in 2023, as customers across the Network Solutions and Services & Support segments prioritized reducing elevated inventory levels amid persistent macroeconomic uncertainty 22. A $292.6 million non-cash goodwill impairment charge was recorded in Q1 2024 for the Network Solutions reporting unit, triggered by decreased market capitalization and reduced future cash flow projections, and was the primary driver of a full-year GAAP operating loss of $427.6 million and net loss of $459.9 million 14 133. GAAP gross margin improved from 29.0% in 2023 to 35.8% in 2024, in part reflecting the step-down of amortization of intangible assets and acquisition-related costs from the Adtran Networks business combination rather than purely operational improvement 22. Operating cash flow swung from negative $45.6 million in 2023 to positive $103.1 million in 2024, aided by a 25.7% reduction in inventory to $269.3 million 22. The Business Efficiency Program, initiated in late 2023, was substantially completed by December 2024, encompassing workforce reductions, facility closures, and discontinuation of copper-based DSL, fixed wireless access, and IoT gateway product lines 22.
FY2023
ADTRAN Holdings reported FY 2023 revenue of $1,149.1 million, up 12.0% year-over-year, with approximately $379.0 million in incremental revenue from the Business Combination with Adtran Networks SE partially offset by a $255.4 million decline driven by customer inventory reduction efforts concentrated in the Subscriber Solutions category 12. GAAP gross margin contracted to 29.0% from 31.9% in 2022, primarily attributable to $89.6 million in acquisition-related adjustments and inventory write-downs, not operational deterioration in the underlying cost structure 12. The GAAP operating loss widened to $221.9 million (19.3% of revenue) from $72.8 million in 2022, including a $37.9 million non-cash goodwill impairment charge on the Services & Support reporting unit and $24.3 million in inventory write-downs related to product line discontinuations 12 13. Net loss attributable to ADTRAN Holdings reached $267.7 million ($3.41 per diluted share) versus $2.0 million in 2022; free cash flow was negative $79.4 million and cash on hand declined to $87.2 million at year-end 11 125. In November 2023, the company launched a Business Efficiency Program targeting $90 million in non-GAAP operating expense reductions for 2024, suspended its quarterly dividend, and initiated site consolidations and a workforce reduction of approximately 5% 9 12.
