1.2 Key Thematic Highlights

Analysis of the quarter reveals several key achievements that underscore the company's strategic progress and operational strength.

Strategic Highlights & Operational Achievements

• Record Revenue Driven by Core Assets: Net sales reached a record $267.0 million, an increase of 13% year-over-year. Management directly attributed this growth to sustained momentum in the company's high-value Data Center and LoRa® portfolios.
• Margin Expansion and Profitability: Significant operating leverage was evident as Non-GAAP adjusted operating margin expanded 180 basis points sequentially and 230 basis points year-over-year to 20.6%. Adjusted EBITDA margin also improved to 23.5%, up 190 basis points from the prior year.
• Strengthened Financial Profile: Through a combination of debt reduction and strong business performance, Semtech dramatically improved its balance sheet. The net leverage ratio was reduced to 1.5 in Q3 FY26, a substantial improvement from 7.2 in the same quarter of the prior year.
• Portfolio Optimization Progress: The company completed the acquisition of a leading Force Sensing portfolio from Qorvo at the beginning of the fourth quarter. Concurrently, management reports making "solid progress on the divestiture of non-core assets," having engaged a financial advisor and received "multiple indications of interest."

These high-level achievements are the direct result of deliberate strategic decisions aimed at enhancing financial flexibility and concentrating resources on high-growth opportunities.

2.0 Strategic Imperatives and Capital Allocation

Management's stated priorities and capital structure optimization are central to understanding how Semtech is positioning itself for future growth. The following analysis evaluates how the company is de-risking its balance sheet to focus investments on its most promising technologies.

Management's Near-Term Priorities

The CEO has articulated three clear priorities that guide the company's operational focus and investment thesis:

1. Capture Growth in Core Assets: This involves making selective strategic investments to enhance capabilities in its core Data Center, LoRa®, and sensing technologies. The recent acquisition of the Force Sensing portfolio is a key example of this strategy in action, aimed at filling capability gaps and accelerating market penetration.
2. Divestiture of Non-Core Assets: Management is actively pursuing the divestiture of certain assets to address corporate margin disparities and sharpen the company's focus on its core business growth drivers. This process is being managed with the assistance of a financial advisor.
3. Strengthen Winning Culture: A core management focus is on "elevating our company mindset to where great is the new normal," establishing a culture where high performance is the standard.

Analysis of Capital Structure Optimization

Semtech has executed a significant restructuring of its debt, fundamentally altering its financial profile and freeing up capital for strategic investment. The key actions include:

• The successful issuance of a $402.5 million 0.00% convertible senior note due in 2030.
• The use of proceeds to fully retire multiple debt instruments, including the 4.00% notes due 2028, a significant portion of the 1.625% notes due 2027, and the outstanding term loan which carried a cash interest rate of approximately 5.8%.
• This financial engineering has had a profound impact: "Currently, annualized interest expense is under $3 million compared to $75 million for the third quarter of last year," a dramatic decrease that directly impacts cash flow and profitability.

This comprehensive debt restructuring provides Semtech with significant balance sheet flexibility. As articulated by the CFO, the reduced interest burden frees up substantial cash flow, enabling the company to "further accelerate growth in our core portfolio and benefit earnings per share." This strategic shift from debt service to innovation investment is a clear driver of future shareholder value. With its balance sheet fortified and capital now reallocated toward innovation, the focus shifts to the operational performance of Semtech's core end markets.

3.0 End-Market Performance Deep Dive

A granular look at Semtech's end markets reveals a tale of two businesses: record-setting growth propelled by secular trends in Infrastructure, juxtaposed with mix-driven margin challenges in the Industrial segment that underscore the urgency of the company's portfolio optimization strategy.

3.1 Infrastructure Market (55% of Sales)

The Infrastructure market delivered net sales of 77.9 million**, representing strong growth of **6% sequentially and 18% year-over-year**. This performance was overwhelmingly driven by the Data Center business, which achieved record net sales of **56.2 million, up 8% sequentially and 30% year-over-year.

Management's commentary highlights how Semtech's low-power solutions directly address the primary constraint facing hyperscalers. As the CEO stated, "As power constraints intensify for our customers... every incremental watt saved in networking connectivity, multiplied by tens of millions of ports, will enable a meaningful increase in compute capacity." This strategic positioning underpins the demand for the following key technologies:

• FiberEdge™ TIAs: Semtech reported record sales for its market-leading TIAs (Transimpedance Amplifiers), noting broad-based demand for 800G products. Management expects volume ramps for 1.6T solutions to commence in early calendar year 2026.
• Linear Pluggable Optics (LPO): The company has secured LPO design wins with "several leading U.S. hyperscalers" for its TIAs and drivers. Management anticipates a "meaningful revenue contribution" from LPO solutions beginning in Q4 FY26.
• CopperEdge™ Active Copper Cables (ACC): A key design win with a "major hyperscaler" is expected to ramp starting in the mid of 2026. Management highlights ACC's key differentiators, including up to 90% lower power consumption than competing DSP-based solutions, lower latency, and excellent signal integrity.

3.2 Industrial Market (29% of Sales)

The Industrial market posted Q3 net sales of $147.2 million, growing 3% sequentially and 12% year-over-year. Performance within the segment was led by strong growth in its flagship LoRa® technology.

• LoRa®-enabled Solutions: This business delivered robust net sales of $40.0 million, representing impressive growth of 10% sequentially and 40% year-over-year. This growth is supported by continued expansion in smart utilities, smart buildings, smart cities, and asset management applications.
• IoT Systems and Connectivity: This business recorded net sales of $88.3 million, which was flat sequentially (-1% Q/Q) but showed solid growth of 7% year-over-year. Management noted strong design win momentum as the IoT market transitions from 4G to 5G technologies.

3.3 High-End Consumer Market (16% of Sales)

The High-End Consumer market generated net sales of $41.9 million, up 2% sequentially and 5% year-over-year.

High-End Consumer year-to-date sales growth of 6% significantly outpaces market metrics, indicating successful market share gains driven by "customer adoptions of our differentiated solutions, and a strong supply chain execution." In an execution of its top priority to Capture Growth in Core Assets, the portfolio was expanded at the start of Q4 with the acquisition of a leading Force Sensing portfolio from Qorvo. This acquisition is strategically designed to combine with existing PerSe® technology to create a "robust set of touch and gesture detection capabilities" for next-generation devices. This detailed look at segment performance provides essential context for evaluating the company's forward-looking guidance.

4.0 Q4 FY2026 Guidance and Forward-Looking Analysis

This section deconstructs management's official outlook for the upcoming quarter, providing context for near-term expectations and identifying key trends to monitor.

Q4 FY2026 Non-GAAP Guidance | Metric | Guidance Range | | :--- | :--- | | Net Sales ($M) | $273.0 +/- 5.0 | | Adjusted Gross Margin (%) | 51.2% +/- 50 bps | | Total Semiconductor Products Gross Margin (%) | 60.5% +/- 50 bps | | Adjusted Operating Expenses, Net (M) | $91.2 +/- 1.0 | | Adjusted Diluted EPS () | $0.43 +/- 0.03 | | Adjusted EBITDA (M) | $56.0 +/- $3.0 |

Management's guidance points to a sequential decline in consolidated adjusted gross margin, revealing a central tension in the current investment story. This near-term pressure is explicitly attributed to a product mix shift within the Industrial end market, with strong projected growth from dilutive "lower-margin cellular modules" paired with a sequential decrease in sales from higher-margin LoRa® products. This highlights the "margin disparities" management aims to solve through its second strategic priority: the Divestiture of Non-Core Assets.

To signal the robust profitability of its strategic growth engines, management provided separate guidance for its Total Semiconductor Products Gross Margin, forecasting a strong 60.5% (+/- 50 bps). This metric underscores the underlying health of the core Data Center, LoRa®, and sensing portfolios, whose strength is currently being obscured by mix effects from the legacy IoT Systems business.

The Q4 net sales outlook by end market is projected as follows:

• Infrastructure: Expected to increase sequentially, with Data Center growth projected at approximately 10%.
• High-End Consumer: Expected to decrease by approximately 3% sequentially, reflecting typical seasonality partially offset by market share gains.
• Industrial: Expected to be about flat, as a decrease in LoRa® sales is anticipated to be offset by growth in IoT Systems and Connectivity.

This guidance sets clear expectations and highlights the key variables that will shape the company's performance as it closes out the fiscal year.
