Good afternoon. Thank you for attending GCT Semiconductor Holding, Inc.'s second quarter 2026 financial results call. All lines will be muted during the presentation portion of the call with an opportunity for questions and answers at the end. Joining the call today are John Schlaefer, GCT's chief executive officer, and Edmund Chung, CFO, to discuss our second quarter 2026 results. During the call, certain statements we make will be forward-looking. These statements are subject to risks and uncertainties, including those set forth in our Safe Harbor provision for forward-looking statements that can be found at the end of our earnings press release and also in our Form 10-Q that will be filed today, which provide further detail about the risks related to our business. We use non-GAAP measures because we believe they provide useful information about our operating performance that should be considered with investors in conjunction with the GAAP measures. A reconciliation of these non-GAAP measures to comparable GAAP measures is included in our earnings release. I would now like to turn the conference over to John Schlaefer. Please, sir, go ahead.

Thank you, and thanks to everyone for joining us today for our second quarter 2026 earnings call. I'll begin by discussing the operational progress we've made during the second quarter and provide an update on where we stand in the commercialization of our 5G platform. Following my remarks, our Chief Financial Officer, Edmund Cheng, Review our second quarter financial results in more detail. When we spoke with you last quarter, we highlighted that 2026 would be a year of continued commercialization as our customers progress from development and integration into early deployments of our 5G chipset. That progression has continued, and the second quarter demonstrates the importance of working closely with customers as they advance through their respective commercialization milestones. While the broader macro environment of several of our customers has influenced the timing of We have not seen any change in the underlying level of customer engagement or the long-term demand of our technology. Rather than viewing the second quarter through the lens of financial performance, we believe it is more meaningful to view it as another important step forward in building a diversified pipeline for the anticipated 5G commercialization ramp. One of our priorities entering 2026 was to broaden the opportunity at hand beyond any single customer application or end market. Today, we believe we have made meaningful progress toward that objective. Our 5G pipeline now spans three strategic growth pillars, terrestrial broadband, satellite and non-terrestrial connectivity, and industrial IoT and specialized networking applications. We believe this and many more. We've been working closely with GCT for a long time. We've been working closely with GCT for a long time. While several customer deployment schedules shifted modestly, These initiatives are moving forward, and we are encouraged by their progress across our partner ecosystem. As operators invest in next-generation broadband infrastructure, we believe our technology is well positioned to support these deployments and participate in the long-term growth of this market. Next, within satellite and non-terrestrial connectivity, we continue expanding our engagement with partners developing direct-to-device and hybrid satellite cellular solutions. We believe This is one of the most compelling long-term opportunities for our technology as terrestrial and satellite networks increasingly converge. Throughout the quarter, we advance development and certification activities with several partners and remain confident in the role our modem technology can play in enabling seamless connectivity across multiple network environments. Our third strategic growth pillar is IoT and specialized networking applications, where we are expanding our presence across industrial, positioning, Hsueh-Hsueh-Hsueh. During the second quarter, we shipped more than 5,100 5G chipsets, representing approximately 71% sequential growth compared to the first quarter. This growth reflects increasing customer engagement across our targeted markets as programs progress through development, certification, and early deployment phases. While the timing of our individual customer ramps can vary, we believe the momentum behind Our platform and growing adoption of our technology provides a strong foundation as we continue scaling 5G chipset commercialization. Across each of these markets, the common theme remains the same. Customer engagement continues to increase, our pipeline continues to broaden, and the underlying demand environment remains healthy. The primary variable today is deployment timing rather than customer interest. As customers complete certification activities and finalize deployment schedules, the timing of commercial production may shift modestly from quarter to quarter, but we remain confident in the long-term opportunity ahead. Our focus continues to be on execution. We are investing in our manufacturing readiness, strengthening our supply chain, supporting customer deployments, and ensuring we are prepared to scale production as commercialization accelerates. While there will inevitably be quarter-to-quarter variability as customers complete their deployment plans, we believe the work we are doing today positions GCT for sustained long-term growth. Overall, we believe the second quarter represents another meaningful milestone in our transition from development to commercialization. The foundations we have built across our technology, customer relationships, and strategic partnerships continues to strengthen, and we are excited about the opportunity ahead. With that, I'll turn the call over to Edmund to discuss our second quarter results. Edmund?

Thank you, John. As John discussed, we view the second quarter as another important step in our commercialization journey. While our reported financial results continue to reflect a business in the early stages of transitioning from development into commercialization, The progress we are making with customers continues to reinforce our confidence in the significant long-term opportunity ahead. One measure of that progress was the continued run in 5G chipset shipments, with more than 5,100 units shipped during the second quarter, representing approximately 71% sequential growth. This growth reflects ongoing advancement of customer programs through integration, certification, and early deployment activities. Before reviewing our financial results, I would like to note that starting from this quarter, we are introducing adjusted EBITDA as an additional supplemental performance metric. Because our reported gap results include significant non-cash fair value adjustments associated with our warring liabilities. We believe Adjust EBITDA provides investors with a more meaningful view of the underlying operating performance of the business as we continue investing in commercialization. With that, I will now review our second quarter 2026 financial results. Further details can be found in the 10Q that will be on file with the SEC. Net revenues decreased by 0.2 million or 18% from 1.2 million for the three months ended June 30th, 2025 to $1 million for the three months ended June 30th, 2026. The change was due to a decrease of 0.2 million in service revenues reflecting the shift to 5G service offerings. Product sales were consistent year over year with growth in 5G product sales. Also our revenue for the first half of this year slightly exceeds the revenue for the full year of 2025. Cost of net revenues increased by 0.4 million or 49% from $0.8 million for the three months ended June 30th, 2025 to $1.2 million for the three months ended June 30th, 2026, largely driven by increased costs from increased unit volume. Our gross margin was 32% for the three months ended June 30th, 2025. Our gross margin for the three months ended June 30th, 2026 was negative. and not representative of our expectations regarding profitability of our products and services in future reporting periods. We expect gross margins to improve as 5G product sales increases and contribute more significantly to the overall revenue. Research and development expenses decreased by $0.2 million from $3.5 million for the three months ended June 30th, 2025 to $3.3 million for the three months ended June 30th, 2026, primarily due to the completion of our 5G chip design project, which results in a $0.5 million reduction in professional services from Alpha, as well as a $0.1 million decrease in stock-based compensation expense. This reduction was partially offset by a $0.4 million increase in payroll-related costs. Sales and marketing expenses remain consistent year-over-year, totaling $1.1 million for the three months ended June 30, 2025, compared to $1 million for the three months ended June 30, 2026. General and administrative expenses decreased by $0.6 million from $3.4 million for the three months end of June 30, 2025, compared to $2.8 million for the three months end of June 30, 2026. The decrease was primarily due to a lower loss resulting from changes in the allowance for credit losses on accounts receivable. Net loss increased by $8.1 million from $13.5 million for the three months ended June 30th, 2025 to $20.4 million for the three months ended June 30th, 2026. Net loss for Q2 2026 also included $12.3 million in losses from change in fair value of common stock warrant liability. driven by increases in our common stock price and the market price of our properly traded warrants during the quarter. Adjusted EBITDA loss decreased by $0.1 million from $6.7 million for the three months ended June 30th, 2025 to $6.6 million for the three months ended June 30th, 2026. While we have not previously reported adjusted EBITDA, we see our stabilized performance here as an important indicator. Shifting to liquidity, we finished the quarter with cash and cash equivalent of $30.2 million. With this improved liquidity, we have the financial flexibility and resources to support the commercial realm of our customer programs. And by now, we have already secured the required production capacity for the remainder of 2026 and through the first quarter of 2027 in anticipation of the expected chip demand. We also have access to our at-the-market equity program, which we initiated in April of 2025. During the quarter, we amended the agreement to increase the maximum aggregated gross proceeds available under the program from $75 million to $120 million, while the total shelf registration maximum capacity remains unchanged at $200 million. These resources provide us with flexibility to support and execute our commercialization strategy as we scale production of our 5G chips. We also have net accounts receivable of 1.1 million and net inventory of 1.5 million. Entering the second half of the year, our financial priorities are changed. While customer deployment timelines can progress at various phases, we continue to expect second half shipments to exceed first half levels as commercialization progresses. Our focus is on disciplined capital allocation, supporting customer production ramps, and converting our growing commercial pipeline into sustainable long-term revenue growth. Although the timing of customer deployments may continue to fluctuate in the near term, We believe the long-term opportunity remains significant, especially in the three strategic pillars which John has mentioned. The investment we have made over the past several years positions GCT well for the next phase of growth. With this, I will turn it back to John.
