Company: Monolithic Power Systems (MPWR)
Bottom line: This report is principally about whether MPWR can convert exceptional AI/server and optical-networking demand into another beat-and-raise quarter—without compromising its roughly mid-55% gross-margin model. The company’s Q2 guide already implies a major step-up in revenue; the more important share-price determinant is likely to be the credibility and magnitude of the second-half outlook, especially for Enterprise Data and Communications.
MPWR guided Q2 revenue to $890–$910 million, versus $804.2 million in Q1 and $664.6 million in Q2 2025. At the $900 million midpoint, that implies roughly 12% sequential growth and 35% year-over-year growth. Management also guided non-GAAP gross margin to 55.3%–55.9% and non-GAAP operating expense to $167–$171 million.
| Metric | Q2 2026 company guide | Midpoint | Q1 2026 actual | Q2 2025 actual |
|---|---|---|---|---|
| Revenue | $890M–$910M | $900M | $804.2M | $664.6M |
| Non-GAAP gross margin | 55.3%–55.9% | 55.6% | 55.5% | 55.5% |
| Non-GAAP opex | $167M–$171M | $169M | $158.3M | $137.6M |
| Non-GAAP tax rate | 15% | 15% | 15% | 15% |
| Diluted shares | 49.1M–49.5M | 49.3M | 49.2M | 48.0M |
Using only the company’s guided assumptions—not a sell-side consensus estimate—the implied non-GAAP EPS range is approximately $5.64–$6.05, with a midpoint near $5.84. That would represent substantial growth from $4.21 in Q2 2025 and $5.10 in Q1 2026.
Enterprise Data was the standout business in Q1: revenue reached $262.8 million, up 12.6% sequentially and 97.7% year over year, to 32.7% of consolidated sales. The segment benefited from AI and server power-management solutions.
More importantly, management raised its 2026 Enterprise Data growth “floor” on the Q1 call to approximately 85% year over year, from the prior 50% floor, citing extended order patterns and improved backlog visibility. This is the fundamental benchmark for the call.
What investors should listen for: - Whether Enterprise Data grew at least in line with, or ahead of, the corporate average in Q2. - Evidence that CPU/server, AI accelerators, and custom ASIC programs are all contributing—not merely one concentrated platform. - Any change to the 85% full-year growth floor. - Commentary on supply availability. Management said it did not view supply constraints as a limitation on its Enterprise Data outlook, which raises the bar for execution.
A maintained or increased floor would support the view that MPWR is taking durable content/share in AI power rather than simply benefiting from a short-lived demand surge.
Communications revenue rose 33.1% sequentially in Q1, driven by power solutions for optical modules and switches. Management indicated that Communications should grow faster than the company average in Q2 and described ordering patterns as extending through the year.
This business matters because it broadens MPWR’s AI infrastructure exposure beyond server-board power. Its products can participate in optical modules, switches, NICs, and other power-intensive rack-level equipment.
Key question: Did the optical and switching ramp continue strongly enough to support an above-corporate growth trajectory into the second half? A positive answer would reduce concerns that MPWR’s AI exposure is overly dependent on one server-power cycle.
MPWR has delivered non-GAAP gross margins around 55.5% for several quarters. The Q2 guide again calls for 55.3%–55.9%, despite very strong revenue growth.
That stability is strategically important. It suggests that higher volumes, a mix shift toward modules, supply-chain costs, and pricing actions are currently balancing out. However, management cautioned in Q1 that it saw possible gross-margin headwinds in the second half.
The key issue is not whether Q2 lands within the 55.3%–55.9% range; it is whether Q3 guidance preserves the mid-55% level.
Watch for: - Module yields and mix effects; - Input-cost or tariff pressure; - Pricing actions intended to protect margin; - Whether higher-value system/module content ultimately becomes accretive to gross margin.
Storage & Computing grew 7.6% sequentially in Q1 but declined 7.5% year over year. The segment contains two very different businesses:
The report should clarify whether robust storage demand is overcoming weaker notebook demand. Investors should not treat segment-level results as a clean read-through to either market.
Automotive was nearly flat sequentially in Q1 at $152.4 million. Management’s framework was for a broadly flat first half followed by a ramp later in 2026 as previously won designs enter production.
Accordingly, Q2 Automotive upside would be welcome, but the more consequential item is confirmation of the expected second-half design-win conversion. Continued delays could pressure confidence in MPWR’s diversification narrative, while an earlier ramp would provide a second growth engine beyond data center.
MPWR is investing in several longer-duration opportunities:
These initiatives reinforce the long-term thesis—expanding from chip-only products toward higher-content power solutions—but investors should be careful not to capitalize immature revenue streams too aggressively in the near-term valuation.
MPWR entered Q2 from a position of financial strength: at March 31 it held $1.37 billion of cash, cash equivalents, and short-term investments, and generated $250.3 million of operating cash flow in Q1.
Inventory is a more nuanced issue. Internal inventory rose to $619.2 million in Q1, or 157 days based on current-quarter revenue. On a next-quarter revenue basis, inventory days fell to 140, suggesting the company was deliberately positioning supply for growth rather than accumulating inventory against weakening demand. Still, investors should monitor:
The company also continues to remediate a previously disclosed material weakness related to controls over deferred-income-tax accounting. Management expects remediation by the end of fiscal 2026. This is not an operating-demand issue, but any delay or accounting revision would be an avoidable overhang.
MPWR closed at $1,286.56 on July 29, down about 15.7% since April 29, while the SOXX semiconductor ETF rose about 6.0% over the same span. MPWR is also roughly 8% below its July 22 close. That relative underperformance suggests the bar may be more manageable than it was immediately after Q1—but it also signals that investors want proof that elevated AI-related growth can persist into the second half.
MPWR’s Q2 report should demonstrate very strong reported growth almost by construction; the company’s own guidance already calls for roughly 34%–37% year-over-year revenue growth. The real debate is whether Q2 establishes a sustainable earnings-power step-up.
For investors, the most valuable evidence would be: continued Enterprise Data momentum, Communications upside, stable mid-55% gross margins, and a Q3 outlook that validates demand beyond the current quarter. If those elements line up, the report would reinforce the case that MPWR is gaining durable share in increasingly power-intensive AI and networking architectures.
