Thanks, Rob, and good morning, everyone. I'll begin with an overview of our second quarter 2026 results, followed by our outlook for the third quarter and full year. We will then open the call for questions. Total revenue for the second quarter increased 11% to $8.1 million compared to $7.3 million in the prior year period. We placed 4 Growth Direct Systems in the quarter. Product revenue, which includes systems and consumables, increased 10% to $5.3 million compared to $4.8 million in Q2 2025. The increase was driven by continued strong consumable growth of more than 20% as new customers move into routine use and existing customers increase the consumable pull-through across their systems. Service revenue increased 13% to $2.8 million compared to $2.5 million in Q2 2025. We completed 9 validations in the second quarter compared to 2 in the prior year period. Validation activity exceeded our expectations and contributed to stronger-than-expected service revenue growth. Recurring revenue increased 14% to $5 million compared to $4.4 million in Q2 2025. Nonrecurring revenue, which is primarily comprised of systems and validation revenue, was $3 million compared to $2.8 million in the prior year period. Turning to margins. Total second quarter gross margin and gross margin percentage were $1.2 million and 15%, compared to $0.3 million and 4%, respectively, in Q2 last year. This was in line with our guidance. Within this, Q2 product margin, which includes systems, software and consumables, improved by 8 percentage points to negative 3% compared to negative 11% in Q2 last year. This was slightly below our expectations due to the timing of some software revenue that we now expect in the second half. Consumable margins improved by 17 percentage points year-over-year, reflecting continued progress on our margin expansion initiatives. Q2 service margin was 49% in the second quarter compared to 32% in Q2 last year, also representing a 17-percentage-point improvement and record quarterly margin for our service business. These results were driven by ongoing cost reduction initiatives, manufacturing efficiencies and service productivity improvements across the business as well as operating leverage from higher volumes. Moving down the P&L. Total operating expenses were $13.5 million in the second quarter compared to $12.4 million in Q2 2025. Within OpEx, R&D expenses were $3.3 million. Sales and marketing expenses were $3.4 million, and G&A expenses were $6.8 million. The increase in OpEx was mainly due to nonrecurring corporate expenses in the period. With respect to non-cash expenses and capital expenditures, depreciation and amortization expense was $0.7 million, and stock-based compensation expense was $1.3 million. Capital expenditures were de minimis in the second quarter. Interest income was $0.1 million and interest expense was $0.6 million in the second quarter. Q2 net loss was $12.9 million compared to a net loss of $11.9 million in the same period last year. Net loss per share was $0.27 in both periods. Starting this quarter, we are reporting adjusted EBITDA loss, a non-GAAP metric that adjusts our GAAP net loss to exclude interest, taxes and non-cash items, such as depreciation, amortization and stock-based compensation. We believe adjusted EBITDA loss provides investors with a clearer view of the actual cash used by our core operations and the underlying performance of the business. Adjusted EBITDA loss for the second quarter was $10.3 million, compared to a loss of $10.1 million in Q2 last year, with the positive impact of higher gross margins offset by higher OpEx in the period. In Q3, we expect adjusted EBITDA loss to improve meaningfully from Q2 as gross margins continue to expand and OpEx returns to lower levels similar to those in Q3 last year. We then expect further sequential improvement in Q4. Now I'll turn to our outlook for the third quarter and full year. For the full year 2026, we are reaffirming our total revenue guidance of $37 million to $41 million, which assumes 30 to 38 system placements. For Q3, we expect revenue of at least $9.5 million, including at least 7 system placements. We continue to expect revenue and system placements to peak in Q4, in line with typical seasonality. Turning to consumables. We expect Q3 revenue to be relatively consistent with Q2 and then increase sequentially in Q4, subject to the timing of customer orders and shipments. Looking at service, we expect service revenue to step up sequentially in Q3 and then again in Q4, based on our current expectations with respect to the timing of installation and validation activities. We now expect to complete at least 27 validations in 2026, with at least 10 in the third quarter. Turning to margin. We expect our Q3 gross margin percentage to be at least 20%. This assumes product margin in the high-single to low-double digits, including slightly positive consumable margin and service margin approaching 50%. We then expect Q4 margin in the mid- to high-20% range, with sequential expansion compared to Q3 across product and service. These expected improvements reflect the continued realization of material cost reductions, manufacturing and service productivity improvements and operating leverage from higher volumes. For the full year, we expect total gross margin of approximately 20%, product margin in the mid- to high-single digits, and service margin between 45% and 50%. Importantly, this margin expansion is a key driver of our expectation for significantly lower cash usage in the second half of the year. Continuing down the P&L. For the full year, we now expect operating expenses of between $51 million to $53 million, and $8 million in non-cash expenses, including depreciation and amortization expense of $3 million and stock compensation expense of $5 million. Of the $8 million in non-cash expenses, approximately $7 million is expected to be recorded in OpEx and approximately $1 million in cost of revenue. We also expect CapEx of $1 million, interest income of $1 million and interest expense of $2 million for the full year. With our 2026 guidance as a starting point, I'd now like to discuss the operating assumptions that support our objective of achieving positive cash flow by the end of 2028. From a revenue perspective, we see multiple growth drivers that should position us to deliver average annual revenue growth of greater than 20% over the next several years. These include continued expansion within our existing top 20 pharma customers, new customer adoption across both top-tier and core pharma accounts, growing recurring revenue driven by higher system utilization and an expanding installed base, increasing contributions from our collaboration with MilliporeSigma across both core and adjacent markets, and favorable industry trends, including accelerating use of full automation, U.S. reshoring and biomanufacturing capacity expansion. Turning to gross margin. We continue to target gross margin of 50% or more exiting 2028, driven by ongoing material cost reductions, manufacturing efficiencies, service productivity improvements and operating leverage from higher volumes. While we expect normal quarterly variability and seasonality to continue, we believe our execution to date, visibility into the business, and progress we are making against our growth and margin initiatives support these long-term objectives. Turning to our balance sheet and liquidity. We ended the second quarter with approximately $20 million in cash, cash equivalents and short-term investments. As we discussed in May, we expect cash usage in the second half of the year to decline meaningfully, assuming revenue increases as anticipated, margin continues to expand and working capital trends improve. As a reminder, cash usage is typically higher in the first half of each year due to normal revenue seasonality and margin improvement trends as well as inventory stocking to support increasing production. In the first half of this year, these factors were exacerbated by 2 temporary working capital headwinds related to the record 16 system placements we made in Q4 2025. First, we collected 100% of the cash from those placements within the fourth quarter last year rather than in Q1 this year as we normally expect. And second, we used more cash than usual to replenish systems inventory in the first half of this year to support our 2026 manufacturing plan. We don't expect these factors to have a meaningful impact on cash usage in the second half of 2026. Separately, this week, we executed a focused efficiency program designed to streamline certain functions and processes that will reduce employee and other expenses as well as cash usage. We expect these actions to reduce expenses and cash usage by around $1 million over the remainder of this year and approximately $3 million annually beginning in 2027. These actions do not impact our plans to continue to invest in key initiatives that are expected to drive future revenue growth and gross margin expansion, including customer sales and support, product development and product cost reduction programs. Combined with our revenue growth and margin expansion initiatives, these actions further support our expectation for meaningfully lower cash usage in the second half of 2026 and beyond. Looking forward, based on our current operating performance and outlook, we believe we are on track to achieve the milestones necessary to access the next $10 million tranche under our debt facility with Trinity Capital later this year, with another $10 million tranche potentially available to us in mid-2027, subject to achievement of the applicable milestones. In addition, the warrants issued in connection with our May financing would provide incremental capital if exercised. Based on our outlook for continued revenue growth, margin expansion and meaningfully declining cash usage, we believe our existing liquidity and access to additional capital sources supports a pathway to positive cash flow. Looking ahead, we plan to maintain our proactive approach to balance sheet management and disciplined capital allocation while also evaluating opportunities to enhance financial flexibility and maximize long-term shareholder value. That concludes my remarks. So at this point, we'll open the call up for questions. Operator?
