Key Highlights

  • Microchip Technology reported June quarter net sales of $1.485 billion, up 13.2 percent sequentially and 38 percent year over year, with non-GAAP EPS of $0.76 beating guidance.
  • Total data center-related net sales across all business units are estimated at approximately $591 million for calendar 2025, expected to grow approximately 69 percent to about $1 billion in calendar 2026.
  • The company's book-to-bill ratio was well above one in the June quarter, the strongest bookings quarter in approximately four years, supporting September quarter guidance of 8 percent sequential growth.
  • Non-GAAP gross margin is guided to 66 to 67 percent for the September quarter, above the company's long-term 65 percent target, aided by a strong licensing quarter and one-time distribution inventory benefits.

Data Center Exposure Spans Far Beyond Switches and Retimers

Microchip Technology (NASDAQ:MCHP) provided its most comprehensive data center disclosure to date, estimating that its Data Center Solutions business unit generated approximately $303 million in calendar 2025 sales, while an additional $288 million came from catalog products across power management, microcontrollers, security, timing, and memory business units that also serve data center customers, for a combined total of approximately $591 million, or 14 percent of calendar 2025 net sales. Management expects this combined figure to grow approximately 69 percent to about $1 billion in calendar 2026, with data center net sales up 97.8 percent year over year in the June quarter alone.

The company's Data Center Solutions unit now has 14 design wins on its PCIe Gen 6 switch and retimer products, up from six as of the prior quarter, spanning both hyperscale and enterprise customers, though management said it remains difficult to quantify design win activity across its much broader catalog product exposure given the sheer number of individual components involved. Management characterized the business as still in early innings following a difficult stretch during the Gen 5 product cycle, when the company was late to market and lost meaningful share before recovering with Gen 6.

Strongest Bookings in Four Years Support Above-Seasonal Guidance

The company said its June quarter was the strongest booking quarter in approximately four years, with a book-to-bill ratio well above one, resulting in higher backlog entering the September quarter. Lead times have begun stretching across many standard products as die and finished goods inventory has been substantially reduced, with constraints emerging in outsourced assembly and test capacity as AI-related demand competes for the same subcontractor capacity, even though the company said its internal fab and assembly capacity remains well below full utilization.

Distribution sell-through grew 17 percent sequentially in the June quarter as distributor customers completed inventory corrections and resumed more normalized buying patterns, with distribution inventory levels at 25 days, near the low end of the company's historical range. Should distributors continue to delay placing longer-term orders despite acknowledging tightening lead times, a dynamic management said is a recurring pattern each cycle as purchasing managers wait until they experience supply disruption before adjusting behavior, near-term revenue visibility could remain more constrained than the strong bookings figures might otherwise suggest.

Gross Margin Guidance Exceeds Long-Term Model on Temporary Factors

Microchip guided September quarter non-GAAP gross margin to 66 to 67 percent, above its long-term 65 percent target, driven by a combination of factors management said are not fully repeatable, including a particularly strong 100 percent-margin licensing quarter, a one-time benefit from a price increase applied to inventory already sitting in the distribution channel, lower new inventory write-offs, and declining underutilization charges as factories continue ramping. Management explicitly cautioned investors not to model gross margin rising further above this level, noting that as these one-time benefits roll off in subsequent quarters, a full quarter of the recently implemented price increase should largely offset the impact and keep margins within a similar range.

Net debt to adjusted EBITDA improved to 2.85 times at quarter end, down from 3.0 times previously, and management expects it to fall below 2.5 times in the September quarter, with all available cash beyond the current dividend continuing to be directed toward debt reduction rather than share buybacks or dividend increases given the company still carries approximately $5.5 billion in gross debt. Aerospace and defense sales grew 45.6 percent year over year in the June quarter, though management cautioned this reflects growth off a depressed prior-year base tied to a broader industry-wide production ramp that primes are still working to size, rather than a rate investors should extrapolate forward.

Conclusion

Microchip's results and unusually detailed data center disclosure suggest the company is positioning its breadth across power, memory, security, and connectivity products as a differentiated advantage relative to peers with narrower AI infrastructure exposure, even as design win visibility across that broad catalog remains difficult to quantify precisely. The strongest bookings quarter in four years, combined with lead times stretching across standard products, points to a demand environment that has shifted from inventory correction to capacity-constrained growth, though management was careful to frame current constraints as limiting upside rather than capping revenue outright. With gross margin guidance already exceeding the company's long-term model on temporary factors and net debt reduction remaining the explicit capital allocation priority, the durability of both the data center growth rate and the elevated margin profile into 2027 are likely to be the key questions investors continue to press on.
