Thanks, John. As a reminder, unless otherwise noted, the financial metrics I'll be discussing today are on a non-GAAP basis. Reconciliations from GAAP to non-GAAP results can be found in today's earnings release as well as on the Investor Center portion of our website. Please note that 2025 sales and margins in the U.S. are no longer impacted by the Tandem Choice program, which ended in 2024. We started the year strong, delivering year-to-date worldwide sales of $475 million or growth of 15%. The majority of this growth was driven by pump and supply volumes with 4% pricing improvement year-over-year, which also contributed to gross margin expansion. For more than a year, we have been setting new quarterly records each and every quarter, both in the U.S. and internationally. Second quarter worldwide sales of $241 million set another record for highest second quarter sales in both the U.S. and OUS markets. U.S. sales in the second quarter were $170 million, representing a 9% increase over the prior year, which was the first full quarter of Mobi availability. The demand for our portfolio of products remains high from new customers and loyalty from our existing customers is evident both in growing renewal and pump supply sales. Our focus on channel management and expansion also drove a meaningful year-over-year increase in average selling price, primarily through our DME channel efforts. Pharmacy volumes remain small relative to our overall pump sales, but we continue to enhance our operational capabilities and validate our assumptions for this opportunity. Our entry into the pharmacy channel was predicated on 2 objectives: to lower out-of-pocket costs for our patients and to drive sales and margins more in line with industry comps. We are still in the early stages but are already seeing examples of patients paying 0 upfront out-of-pocket under our current agreements. The pharmacy contracts we have signed are similar reimbursement structure and revenue recognition to our DME contracts, but we also continue to discuss pay-as-you-go models, which we are confident in our ability to support. Our experience to date underscores our confidence in meeting our business goals for pharmacy expansion. We are working aggressively to build on this opportunity in multiple ways. Our team is making great progress in our conversations with PBMs and payers to expand insurance coverage under the pharmacy benefit. We currently have approximately 30% of U.S. lives under coverage and anticipate signing additional meaningful contracts in the upcoming weeks that will be available immediately. We are also expanding our pharmacy distribution network to maximize the patient access we currently have, which provided incremental benefit this quarter through initial stocking orders. Last, we are advancing our strategy by beginning the contracting process to offer patient access for t:slim supplies in the pharmacy channel. Considering we have an installed base of several hundred thousand t:slim users in the U.S., this could provide meaningful benefit as we build on our pharmacy coverage for t:slim beginning in the fourth quarter of this year. Recently, CMS issued a proposed rule that updates Medicare payment policies and rates for DME providers, including 2 changes for insulin pumps. The first is a proposal to alter the reimbursement structure for pumps from a 13-month rental to a pay-as-you-go model. Similar to my pharmacy comment, we are confident in our ability to support pay-as-you-go. The second proposal is to include pumps in competitive bidding, which is a Medicare initiative designed to reduce costs and improve access. Overall, traditional Medicare represents a small portion of our business at less than 10% of our U.S. sales. Should CMS move forward with the proposals as written, it's an opportunity to bring Tandem's technology to more people living with diabetes and the structural changes may ultimately provide benefit to our business. We plan to participate in the current comment period and anticipate final rulings in November. Now I will turn to our performance outside the United States. As a reminder, last quarter, we noted a $5 million shift in timing of sales from the second quarter into the first quarter. In the second quarter, we also experienced slight headwinds from distributor inventory adjustments in preparation for our transition to direct operations in 2026, yet we were still able to deliver record second quarter sales of $70 million. We saw a benefit in the quarter from early traction in renewals as well as favorable currency dynamics. Moving to our company's margin performance. A key objective for our business is demonstrating improvement in profit margins. Our plans for driving gross margin expansion and operating leverage this year are on track as evidenced by our second quarter results. Our second quarter gross margin was 52%, reflecting an increase both year-over-year and compared to the first quarter. Pricing was the primary driver, offset partially by product mix and non-manufacturing costs. Importantly, the Mobi platform is a key driver to our long-term gross margin expansion and its benefits are beginning to materialize as we gain more manufacturing experience and scale volumes. The Mobi cost per pump has already improved meaningfully year-over- year, and the platform margins are expected to continue improving over the course of the year as pump and cartridge volumes grow. From an operating expense perspective, I'm particularly impressed by the execution of our teams to deliver on our profitability targets while making meaningful progress to prepare our people, process and technology for our next wave of growth. We are taking action to both modernize how we go to market through a combination of efforts within the sales force, channel, technology and process redesign with the goals of offering an elevated customer experience while scaling headcount more efficiently. These changes position us to compete in a highly competitive market while also delivering profitable growth. As a result, operating expenses grew 10% year-over-year, driven by SG&A investments. Going forward, we expect these investments to be offset by savings, which will begin to provide benefit in the second half of the year. R&D expenses were essentially flat year-over-year, a result of our continued focus on efficient delivery of new innovations. We ended the quarter with $315 million in total cash and investments. The quarter had 2 noteworthy uses of cash. First, our 2025 convertible notes matured in May, and we settled the balance of $41 million using existing cash. Second, we paid $8 million as the first of 5 annual installments towards a $36 million settlement agreement that includes a 10-year worldwide nonexclusive patent license and a covenant not to suit. We view this as a positive development that will allow us to focus on innovation in our business and for our customers. Looking at 2025 overall, we are on a path to achieving double-digit growth of $1 billion in 2025 worldwide sales and have updated our guidance accordingly. In the U.S., we anticipate more moderate growth in the back half of the year, which reflects the U.S. dynamics between our commercial evolution and the competitive environment, partially offset by benefit from the pharmacy channel opportunity. Outside the United States, our sales performance confidence has increased as we continue to drive our international strategy. In particular, we had assumed a $15 million to $20 million headwind associated with going direct. We now believe the headwind will be reduced to approximately $10 million, and we expect continued strength in growing the market overall. With these updated assumptions, the expected geographic mix will be sales of approximately $700 million in the U.S. and $300 million outside the U.S. Turning to margin expectations. We are executing to both our manufacturing and operational goals. We anticipate achievement of gross margin in the range of 53% to 54% as a reflection of the change in geographic mix of sales and expect to see margins expand across the quarters as pump sales increase and additional Mobi efficiencies are gained. Impact from tariffs has been negligible, and we expect that to continue. Importantly, we remain on track to reach the quarterly milestone of 60% gross margin as we exit 2026. From an adjusted EBITDA perspective, we are no longer excluding expenses for in-process research and development in our non-GAAP results in order to align with views recently expressed by the SEC. Therefore, our adjusted EBITDA guidance for 2025 is now being recast from positive 3% to negative 5%. This change is solely driven by negative 8 points of margin for the $75 million IP R&D charge associated with AMF Medical that occurred in the first quarter. In support of our operational EBITDA margin goals, even with our growth investments, initiatives to deliver efficiencies are expected to begin materializing in the back half of 2025 with increasing benefit in future years. We also anticipate returning to positive free cash flow in the second half of 2025. I'll now turn the call back to John.
