„Preliminary Q4 revenue came in as expected with non-GAAP profitability at the upper end of our guidance driven by continued gross margin improvements and lower operating expenses. Although revenues continued to remain challenging due to the macroeconomic environment and elevated customer inventories. we believe the fundamental demand landscape remains unchanged. Service providers continue to pursue the same objectives of expanding their fiber footprint and enhancing bandwidth, necessitating global infrastructure buildouts. With the ongoing implementation of our cost improvement measures, we believe that we are transforming into a more streamlined and efficient company.

„We anticipate that the ongoing uncertainty affecting customer spending will extend into 2024. We are actively addressing the challenges in our industry and have implemented a business efficiency program to ensure improvement in long-term shareholder return. Through this program, we are aiming to lower our costs by $90 million by the end of 2024 as compared to 2023. Although the environment has proven to be very challenging, interest in our products continues to grow as we gained market share and added new customers during the quarter. We expect the combination of our continued growth in market share with our new operating model to substantially improve returns to all our stakeholders.“ – Tom Stanton, Chairman and Chief Executive Officer 9
„While revenue and GAAP operating margin continue to be challenging as customers remain focused on reducing inventory levels and managing capital expenses, our Q3 non-GAAP operating margin was at the upper end of our guidance, helped by the planned reduction in our operating expenses and improved non-GAAP gross margins. Additionally, the strengthened U.S. dollar had a negative impact on revenue generated outside of the U.S. Moving forward through the end of this year, we will continue to focus on aligning our operating model to reflect the current environment. Finally, during the third quarter, ADTRAN continued to add new customers in both Europe and the U.S., further strengthening our market share position and, with our broad portfolio and geographic reach, uniquely positioning us to benefit from what we anticipate to be a return to normalized spending.“ – Tom Stanton, Chairman and Chief Executive Officer 8

„As mentioned in our pre-release, the results of the quarter were impacted by slowing sales predominately in our Subscriber Solutions category. Although we expect customer inventory management efforts to continue to affect our near-term results, the underlying demand to upgrade and deploy fiber networks is at an unprecedented high and we are ideally positioned to capitalize on this opportunity.“ – Tom Stanton, Chairman and Chief Executive Officer 4
„Growing customer concerns over inventory stocking levels affected our first quarter Subscriber Solutions category. We believe that this over-supply condition in CPE products will continue into the second quarter. Revenue for our Access and Optical Networking products grew sequentially. Supply constraints, however, limited our flexibility to clear past-due backlog across all product categories. We believe that the inventory impact is transitory, and we expect to see some improvement during the second quarter. We plan to adjust expenses in the near term to reflect current conditions, however we do not see any material changes to our near-term opportunities and our long-term growth catalysts as carriers around the world race to upgrade their networks to fiber.“ – Tom Stanton, Chief Executive Officer 3

Balance Sheet & Cash Flow ($m)#

Point-in-time balance sheet items (e.g. cash, financial debt) and cash flow items (operating cash flow, investments/capex) per fiscal year, half-year and quarter. Balance sheet values are as of the period end, flow items cover the period. Derived values are marked and are calculated, for example, as: net debt = financial debt − cash; free cash flow = operating cash flow − capex; the click popover shows formula and inputs. All values are extracted automatically from the filings; errors are possible; please verify decision-relevant figures yourself by clicking through to the linked original.

Revenue by Type (as of 2026-Q2 · USDm · 4/7)#

Revenue split by segment or product type, exactly as the company itself reports it. The basis is stated next to each value (3, 6 or 12 months); segment totals can deviate from group revenue (reconciliation/consolidation items). If the company changes its segment structure, older structures are kept in the expandable part. Rows in grey are no longer reported separately by the company; they show the last available figures and are never extrapolated.

Reported KPIs (as disclosed) (314)#

Figures the company discloses itself in addition to the standard financials; order intake, recurring revenue, user or unit counts, adjusted measures. These “story KPIs” usually slip through standard databases; here they are collected as reported, with no calculation of our own. Important: the definition comes from the company itself and can differ from firm to firm; period and source are stated next to every value.

Company-specific KPIs verbatim from the filings (English, as disclosed; not normalised). Balance-sheet and boilerplate items filtered.

Development#

A condensed summary per reporting period as running text: what changed operationally, which drivers management names, how earnings and cash flow developed. Most recent period first, grouped by year; each text is written from the original report of that period, superscript numbers lead to the source.

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.
