Following the extensive analysis and evaluation, we made a clear decision, move to a single national distributor partner while strengthening the model with high-performing regional distributors. As part of this transition, we are exiting Boise Cascade as a national distributor for decking and railing. I personally want to thank them for their years of trusted distribution partnership with Trex. This isn't about the past. It's about where the market is going and how we best position Trex for the future.
Going forward, our structure is simpler and more focused. SBP is our sole national distributor and a select group of strong regional distributors in target markets, including WS Building Materials, Coastal Forest Products and International Wood Products, Weyerhaeuser, BlueLinx, Taiga, Nicholson & Cates, Stella-Jones, and Manufacturers Reserve Supply. Both Trex and SBP share a common vision of growth through continuous innovation and bold decision-making.
SBP is exactly the right distribution partner to help Trex execute our strategy and accelerate our return to rapid growth and market share gains. Similarly, we chose regional distribution partners very intentionally for their service, local market strength, and willingness to invest in growing the Trex category. Together, this network of distributors fully replaces Boise's footprint with no loss of coverage and maintains coast-to-coast availability.
At its core, this move is about building a distribution network that's simpler, faster, and more effective. We have approached this transition with a high level of rigor to ensure a smooth and seamless execution. In preparation, we have coordinated so that our new distributor partners will begin receiving material within the coming week. At the same time, onboarding and training with these new distributor partners is now underway, supported by dedicated teams specifically assigned to manage and oversee execution.
With these measures in place, we expect the transition to be largely complete within 30 days with no material disruption to supply. This positions us more strongly to capture incremental share in an evolving channel and to outperform the broader Repair and Remodel market over time. It also creates an opportunity to realize near-term volume upside as demand transitions to Trex. With that, I'll turn it over to Prith to walk through the financial implications.

Thank you, Adam. I'll cover three areas. First, our preliminary Q2 results, which are subject to change upon completion of review by our auditing firm. Second, the financial impact of the distribution transition and third our outlook for the full year. Please note that the preliminary second quarter results and our revised 2026 guidance are provided in the financial section of today's press release.
Starting with our performance in the second quarter. As Adam mentioned, we are very pleased to report that we had a strong quarter with preliminary net sales of approximately $418 million, coming in well above our expected range of $388 million to $403 million and adjusted EBITDA of approximately $112 million.
This performance was driven by strong customer demand even in a continued challenging macroeconomic environment. Importantly, this demand was also broad-based across both our distribution channels and product lines with no benefit from load-in purchases by new or expanded distribution partners. We will provide further details when we report Q2 results on August 4, 2026.
Turning to the distribution transition. At a high level, we view the financial impact as limited, manageable, and primarily timing related. In the near term, we may see modest shipment timing
