Timothy P. Santo
Thank you, Tom, and thank you for joining us this morning. As I shared last quarter, my focus remains on 3 key priorities: strengthening our capital structure, enhancing the capabilities of the finance organization and deepening our engagement with stakeholders. These are fundamental to delivering long-term sustainable value for our stockholders. We are making solid progress across each of these areas. First, we are taking meaningful steps to improve our capital structure. We generated $32.2 million in operating cash and $18.3 million in free cash flow this quarter with $106 million of cash available on our balance sheet. We are advancing efforts to raise capital through the sale of noncore assets, including our Huntsville campus, which I will speak further shortly. Meanwhile, availability on our revolving credit facility has more than doubled and will continue to expand as we grow non-GAAP EBIT and accelerate our free cash flow. Second, we've strengthened our financial organization through strategic additions to my senior leadership team. These hires improve our ability to manage the complexities of our current structure and support execution. We will continue investing in talent to ensure finance remains a strategic asset of our business. Finally, we've deepened our engagement with external stakeholders. We've expanded participation in investor and industry conferences and are pursuing broader research coverage. We remain committed to transparency, listening and increased accessibility as we execute our strategy, and we will continue to expand over the coming quarters. With that, let's take a look at the financial results for the second quarter of 2025. ADTRAN's second quarter performance reflects an improving industry environment and our ability to deliver strong operating results. We are adding new customers and expanding our presence with existing ones, driving market share gains, and we are continuing to scale our business. ADTRAN delivered second quarter revenue of $265.1 million, up 17% year-over-year and 7% sequentially, exceeding the high end of our original guidance range and reinforcing strong execution and momentum. Our Network Solutions segment contributed revenue of $219.5 million, accounting for approximately 83% of total revenue in Q2 compared to 79% in the prior year. Our Services & Support segment generated $45.6 million of revenue, representing 17% of revenue in Q2 2025 compared to 21% in Q2 2024, largely resulting from the significant growth and outperformance in Network Solutions. Moving on to product categories. Our Optical Networking Solutions revenue was $90.1 million or 34% of total revenue. As predicted, Optical Networking Solutions revenue was higher, growing by 22% year-over-year. Access and Aggregation delivered revenue of $91.2 million or approximately 34% of total revenue and increased 30% year-over-year. Subscriber Solutions was $83.8 million or 32% of total revenue, increasing 2% year-over-year. Geographically, non-U.S. revenue accounted for 55% of the total, while U.S. revenue comprised 45%. Additionally, one customer represented more than 10% of our Q2 revenue. This quarter's non-GAAP gross margin was 41.4%. While gross margin was in line with previous trends, the quarter-over-quarter decline was primarily driven by product and customer mix, higher transportation costs as we strategically reposition products to mitigate tariff exposure. We maintain our longer-term target ratio of 42% to 43%. Non-GAAP operating expenses were $101.7 million, up from $95.5 million in Q1 and $93 million in Q2 last year, mainly due to currency fluctuations and higher sales commissions. Non-GAAP operating profit was $8 million or 3% of revenue, above the midpoint of our 0% to 4% outlook. This compares to $9.8 million or 3.9% of revenue in Q1 2025 and $1.4 million or 0.6% of revenue 1 year ago. The year-over-year operating margin and profitability improvement was primarily driven by higher revenue. Although we tightly manage our costs, OpEx increased due to fluctuations in European currencies and higher sales-related expenses. Currency fluctuations were a meaningful factor this quarter. While we are generally well positioned from a natural hedging standpoint on profitability, we believe that looking ahead, currency will continue to play a role in our financial results. Since joining ADTRAN in March, I've prioritized strengthening FX management, taking early steps to build a more robust hedging strategy. These efforts support our broader goal of enhancing transparency and resilience in a more complex global environment. Non-GAAP tax expense in Q2 2025 was $628,000, reflecting higher taxable income in the U.S. We reported a non-GAAP net loss of $256,000 or $0.00 on an earnings per share basis. This compares to non-GAAP net income of $0.03 per share in Q1 2025 and a net loss of $0.13 per share in Q2 2024. Turning to the balance sheet and cash flow statement. In the second quarter, we continued to make meaningful progress in strengthening our financial position. Net working capital improved by $21.7 million sequentially, reaching $226.6 million, supported by a continued reduction in inventories and stronger collections. Trade accounts receivable was $164.8 million at quarter end, resulting in DSO of 57 days, an improvement from 60 days in the prior quarter. Inventory levels declined to $240.1 million at the end of the quarter, a decrease of $13.6 million sequentially. Correspondingly, days inventory outstanding significantly decreased by 17 days to 135 days in Q2 2025. Accounts payable were $178.3 million with days payable outstanding of 70 days. Strengthening our balance sheet remains a key strategic priority. As mentioned before, operating cash flow was $32.2 million, and we had free cash flow of $18.3 million for Q2 2025. This is compared to $24.5 million in Q1 2025 and $3.9 million during Q2 2024. We ended Q2 with $106.3 million in cash and cash equivalents, a $5 million sequential increase, reflecting solid improvement in our liquidity. It is worth noting that this increase was achieved net of certain ADTRAN Networks SE share repurchases under our DPLTA agreement, underscoring our disciplined cash management and strong operational execution. We remain focused on materially strengthening our financial position in 2025 with the ultimate goal of achieving a positive net cash position. As mentioned earlier, we continue to evaluate opportunities to monetize certain noncore assets, including some of our Huntsville properties. Although we were close to closing a deal this past quarter, that deal is not yet finalized, and we continue to work on finding additional purchases for this unique property. Further, with our improved credit positioning, we are evaluating a sale-leaseback transaction on our East Tower. We are approaching these decisions thoughtfully and increasingly from a position of strength. We are pleased with our second quarter performance and encouraged by the signs of continued improvement across the industry. We are beginning to experience the benefits of scale and expect that momentum to build in the second half as revenue growth continues. Foreign exchange has generally had a positive impact on our business in Q2, although it contributed to slightly higher operating expenses, largely due to the weaker U.S. dollar relative to the euro. On a constant currency basis, we expect OpEx to remain consistent with prior quarter levels. As I mentioned since joining in March, I prioritized building stronger FX management and reporting capabilities. Our capital allocation remains focused on deleveraging and continuing to evaluate opportunities to streamline the portfolio. Before turning to our outlook for the third quarter, I want to briefly address our approach to guidance. A few weeks ago, we issued a press release preannouncing that Q2 revenue would exceed our prior guidance range. While that intraday disclosure update may have seemed atypical, it was required under German disclosure rules we inherited through the ADVA merger. These regulations mandate rapid public disclosure of any material deviation, positive or negative from previously issued guidance. As such, we provide quarterly guidance rather than annual guidance to remain compliant and avoid unnecessary disclosure burdens. Looking ahead to the third quarter of 2025, we expect revenue between $270 million and $280 million and anticipate a non-GAAP operating margin of 3% to 7%. This outlook excludes potential tariff impacts due to ongoing uncertainty surrounding global trade policy and broader macroeconomic conditions.
