Summary
Summary of the 8-K filed May 1, 2025. Cited figures are marked; the original filing is the authoritative source.
Monolithic Power Systems (MPWR) reported first-quarter 2025 results on May 1, 2025, with revenue of $637.6 milliona, up 2.6% sequentially and 39.2% year over year, setting a new quarterly record.
GAAP net income was $133.8 millionb ($2.79 per diluted share), versus $92.5 million ($1.89) a year earlier. Non-GAAP net income was $193.8 million ($4.04 per diluted share), down 1.2% from the fourth quarter's $4.09 but up 43.8% year over year. GAAP gross margin was 55.4% (flat sequentially) and non-GAAP gross margin was 55.7%, roughly unchanged year over year.
GAAP operating income reached $168.8 millionc, a 26.5% operating margin. Growth was driven by Storage and Computing, which rose 38% sequentially to $188.5 million on memory and notebook demand, and Automotive, which reached $144.9 million, the third straight quarter of double-digit sequential growth. Enterprise Data declined 31.8% sequentially to $132.9 million, falling from 31.3% to 20.8% of revenue, though management said it continues to win designs across major Enterprise Data customers with ramps expected in the second half of 2025.
Working capital warranted attention: receivables rose to 31 days of sales outstanding from 25, and inventory reached $454.8 milliond, or 146 days of current-quarter revenue, up 8 days sequentially. For Q2 2025, management guided to revenue of $640–660 million, non-GAAP gross margin of 55.2%–55.8%, and non-GAAP operating expenses of $132.6–136.6 million, with a 15% non-GAAP tax rate for 2025.
Cash, cash equivalents and short-term investments totaled $1,026.7 million, and operating cash flow was $256.4 million. The 8-K itself is a furnishing of earnings materials under Item 2.02, so the substance lies in the exhibits.

03—Questions
Frequently Asked Questions
What drove the strong sequential revenue growth in Q1 2025?
Storage and Computing grew 38% QoQ on demand for memory and notebook power solutions, and Automotive grew 12.9% QoQ on ADAS, body electronics and infotainment. Communications (up 12.3%) and Industrial (up 4.3%) also improved, while Consumer declined 0.6% and Enterprise Data fell 31.8%.
Why did Enterprise Data decline so sharply, and when is recovery expected?
The filing does not explain the sequential drop in detail. Management said it continues to win designs across all major Enterprise Data customers, with revenue ramps expected in the second half of 2025. Enterprise Data's share of revenue fell to 20.8% from 31.3% in Q4 2024.
Is the rise in inventory and receivables a concern?
Inventory increased to $454.8M from $419.6M, and days of inventory rose to 146 from 138. Receivables rose to $214.9M, with DSO up to 31 days from 25. Management said it is balancing market uncertainty against readiness for upturns. Investors should watch whether these build-ups convert to revenue or lead to margin pressure.
What is the outlook for Q2 2025 and margins?
Management guided to revenue of $640M–$660M, GAAP gross margin of 54.9%–55.5% (non-GAAP 55.2%–55.8%), and non-GAAP opex of $132.6M–$136.6M. The non-GAAP tax rate is 15% for 2025, and fully diluted shares are expected at 47.9–48.3 million.
Why do GAAP and non-GAAP results differ so much?
The gap is mainly stock-based compensation and related expenses, which were $53.8M in Q1 2025 (about $1.7M in cost of goods sold). Non-GAAP net income of $193.8M compares with GAAP net income of $133.8M, and the difference also reflects a $5.9M tax effect. Investors should review the reconciliation tables, since the company's non-GAAP measures are not comparable to those of other companies.
