Thank you. As Melissa highlighted, our strategic expansion into clinical services is running well ahead of schedule after our accelerated progress on both organic growth and M&A execution in Q2. Year-to-date, we've completed 3 acquisitions that have significantly expanded our footprint and operational efficiency while adding more than $20 million of revenue and $6.3 million of projected annualized adjusted EBITDA at our targeted mid-single-digit acquisition multiples. We're well ahead of the capital deployment pace we targeted in our value creation plan, and we have even more great opportunities in the pipeline, though we do expect the pace of acquisition activity to slow in the second half of the year. We expect our cash balance to build into year-end, driven by free cash flow generation and the Joby performance earn-out of $17.5 million that we believe we are on track to receive in full by year-end. On the industry front, we've seen a continued recovery in DCD donors versus the low point in Q3 2025, with a low single-digit sequential increase in Q2 2026. While still down year-over-year due to a tough comp, we should start to see year-over-year industry donor growth in the second half of the year. Heart, liver and lung transplants continue to grow, thanks in large part to rising penetration rates of NRP, which, as a reminder, has been shown to result in approximately 50% more usable organs per DCD donor on average. In fact, NRP penetration continued its march forward this quarter, rising to approximately 59% of DCD donors in Q2 2026 versus 57% in Q1 2026. I'll now turn to the second quarter financial results, starting with Logistics, where year-over-year revenue growth moderated to 6.9% as we lapped 2 new large customer wins that started in Q2 2025. Logistics revenue increased approximately 1% sequentially versus Q1 2026, which was somewhat below our expectations. The dynamic of shorter trips that we called out last quarter continued into Q2 2026, driven by strength in our organ procurement organization customers, along with some softness in transplant centers. As Melissa highlighted earlier, we're expecting a roughly 3% Logistics revenue headwind driven by a nonexclusive customer that significantly reduced their flying with us for one organ type starting in June. We believe that the circumstances around this situation are unique and that the high customer retention rate we've experienced historically will persist moving forward. Our pipeline of new logistics customers remains strong, and we expect contributions from new customers as well as growth from existing customers to largely bridge the gap by the end of the year. On the profit front, Logistics gross margin fell to 18.4% in Q2 '26 versus 19.3% in Q1 2026 and our expectation of approximately 20%. There were several factors driving the lower-than-expected logistics gross margin, including a higher fuel surcharge. As a reminder, our Logistics contracts typically contain a fuel surcharge provision where we pass through fuel costs above an agreed-upon threshold, usually in the low $4 per gallon range. The fuel surcharge increases our revenue, but has no impact on our gross profit dollars, reducing our gross margin. Our gross margin, excluding fuel surcharge revenue and cost was 19% in Q2 2026. While we have fuel surcharge provisions in all of our logistics contracts, we have a small number of contracts, too, where the pass-through mechanism either kicks in at a higher price above current levels or is capped. This lowered gross margin by approximately 30 basis points. Lastly, customer mix shift remained unfavorable with a larger concentration of short lower-margin trips this quarter. We also experienced lower profitability on our owned fleet, driven in part by higher-than-average unscheduled maintenance expenses and lower ground margins compared to the year ago period due to a mix shift to lower-margin third-party vehicles, which we expect to correct in the coming quarters. We now expect gross margin to be in the 18.5% to 20% range in the second half of the year, but we are confident in our ability to restore Logistics gross margin solidly to our 20% target for 2027. We'll always see some volatility in Logistics margin, particularly given the inherently unpredictable nature of unscheduled maintenance. However, we have several initiatives underway to structurally increase Logistics gross margins back to our target, largely driven by the elimination of less efficient, higher cost operators and favorable changes to our supply contracts as we allocate more hours to better performing providers. I'll now turn to the Clinical segment and the company's overall performance. Total revenue increased 60.7% to $72.5 million in Q2 2026 versus $45.1 million in the prior year period, driven by organic growth in logistics, the addition of our clinical business through the acquisition of Keystone in Q3 2025 and the contribution from Clinical acquisitions completed during Q2 2026. Clinical revenue rose 22.6% sequentially to $24.3 million in Q2 2026 versus $19.8 million in Q1 2026. Excluding clinical acquisitions completed during the quarter, clinical revenue rose 15.1% sequentially in Q2 '26 versus Q1 '26, driven primarily by Transplant Clinical revenue, which rose 23.8% and other clinical revenue that rose 6.5%. Gross profit increased 68.9% to $15.2 million in Q2 2026 versus $9 million in the prior year period, driven by the addition of our Clinical business and the contribution from Clinical acquisitions completed during Q2 2026. This was partially offset by a modest decline in Logistics gross profit, as previously discussed. Gross margin increased 100 basis points to 21% in Q2 2026 versus 20% in the prior year period, driven primarily by the positive mix impact from the addition of our Clinical business and the contribution from Clinical acquisitions completed during the quarter, partially offset by the decline in Logistics gross margin. Clinical gross profit increased 27.8% sequentially to $6.3 million in Q2 2026 versus $5 million in Q1 2026. Clinical gross margin increased to 26.1% in Q2 2026 versus 25% in Q1 2026. As we noted in recent quarters, given the noise associated with last year's transactions, year-over-year comparisons of SG&A and adjusted EBITDA are not particularly meaningful. So we'll discuss those results on a sequential basis. Adjusted SG&A decreased approximately $100,000 to $9.1 million in Q2 2026 versus $9.2 million in Q1 2026, primarily driven by the timing of expenses in each period. Adjusted EBITDA was $7.9 million in Q2 2026 versus $6.4 million in Q1 2026. Adjusted EBITDA margin rose to 10.9% in Q2 2026 versus 9.5% in Q1 '26. The 140 basis point sequential increase in adjusted EBITDA margin was driven by the increase in Clinical gross margin and the mix shift to Clinical, partially offset by the reduction in Logistics gross margin. Operating cash flow was $5.7 million in Q2 '26. The $2.2 million difference between adjusted EBITDA and operating cash flow was driven primarily by a $1.7 million increase in working capital, given the accelerated growth in Clinical and nonrecurring transaction-related cash costs. Capital expenditures of $2.8 million in Q2 2026 were driven primarily by aircraft capitalized maintenance, which was elevated this quarter given the completion of 2 sets of engine overhauls, the only scheduled engine overhauls for 2026. Free cash flow was $2.9 million in Q2 2026, and there were no aircraft or engine acquisitions this quarter. As mentioned, we're encouraged by the second consecutive quarter of cash generation, especially considering the timing of expenses and nonrecurring transaction-related cash costs that burdened cash flow. Moving to the outlook. We are increasing our 2026 revenue guidance to a range of $285 million to $295 million, up from $260 million to $275 million previously. We are also increasing our 2026 adjusted EBITDA guidance to a range of $33 million to $35 million, up from $29 million to $33 million previously. At a high level, we're seeing the benefit of accelerated clinical growth and our acquisitions and a significantly increased revenue guide, while given the timing of the short-term margin headwinds we're seeing in Logistics, the profit benefits of the same are partially offset in our EBITDA guide for 2026. As discussed, the Logistics gross margin is expected to improve in the second half of the year and return to our 20% target in 2027, restoring the full underlying earnings power of the business moving into next year. Assuming the recent Clinical acquisitions closed on January 1, 2026, our 2026 revenue range would be $295 million to $305 million, and our adjusted EBITDA range would be $36 million to $38 million. We continue to expect free cash flow before aircraft acquisitions of $15 million to $22 million in 2026 as the increase in adjusted EBITDA is offset by higher nonrecurring cash costs related to the accelerated pace of acquisition activity during the year as well as anticipated working capital build associated with the faster pace of growth in Transplant Clinical. In Logistics, we expect revenue to decrease high single digits sequentially in Q3 versus Q2, driven by the 3% revenue headwind we discussed earlier as well as the expected summer seasonality that is typical in Q3. Over the last 3 years, heart, liver and lung industry transplant volumes fell between 3% and 6% between Q2 and Q3. As we've said before, our customer base could perform better or worse than the industry in any given quarter. From July to date, we have seen fewer organs being accepted for transplant at several of our centers. By Q4, we expect Logistics revenue to recover to near Q2 2026 levels. As discussed, Logistics gross margin is expected to gradually improve to the 18.5% to 20% range over the balance of the year. As we mentioned earlier, we've already put in place several initiatives to structurally drive Logistics gross margins back to our 20% target for 2027. Clinical revenue is expected to grow approximately 20% sequentially from Q2 to Q3, driven by continued growth in the base business, along with a full quarter contribution from the recent clinical acquisitions that closed during Q2 2026. In Q4, we expect mid-single-digit clinical sequential revenue growth versus Q3. We expect clinical gross margins to increase to the 27% to 28% range in the second half of the year, driven by mix shift to the higher-margin Transplant Clinical business. Our adjusted SG&A is expected to remain in the low $9 million range for the balance of the year. In summary, we're excited about the growth potential of our integrated service offering in Transplant, the performance of our Clinical business and the increasing cash generation that has started to come through in the first half of the year despite some short-term headwinds in Logistics that we're proactively addressing. The best is yet to come, and we look forward to seeing more and more of the financial benefits of our strategic plan shine through in the coming quarters. We're participating in several investor conferences over the next few weeks, including Needham's Healthcare Conference and the Lake Street Investor Conference. We hope to see many of you there. With that, I'll turn it back to the operator for Q&A.
