non-GAAP financial
"Non-GAAP net income, non-GAAP net income per share, non-GAAP gross margin, non-GAAP operating expenses"
Non-GAAP refers to financial measures that companies use to show their earnings or performance without including certain expenses or income that are often added back to give a different picture. It matters because it can make a company's results look better or more favorable, but it may also hide important costs, so investors need to look at both GAAP (official rules) and non-GAAP numbers to get a full understanding.
stock-based compensation financial
"Total stock-based compensation and related expenses, including approximately $1.7 million charged to cost of goods sold, was $48.5 million"
Stock-based compensation is when a company pays employees, directors or consultants with shares or the right to buy shares instead of or in addition to cash. It matters to investors because issuing stock or options spreads ownership thinner (like cutting a pie into more slices), which can reduce each existing share’s claim on profits and can also change reported earnings; investors watch it to assess true cost of running the business and how management is incentivized.
Enterprise Data financial
"In our Enterprise Data market, first quarter 2026 revenue of $262.8 million increased 12.6% from the fourth quarter of 2025"
Days of Inventory financial
"Days of inventory of 157 days at the end of the first quarter of 2026 was 4 days higher than at the end of the fourth quarter of 2025"
Days of inventory measures how many days, on average, a company holds goods before selling them — think of it as how long items sit on a store shelf or in a pantry. Investors use it to judge operational efficiency and risk: a lower number suggests faster sales and healthier cash flow, while a higher number can signal slow demand, excess stock or potential write-downs.
forward-looking statements regulatory
"This earnings commentary contains, and statements that will be made during the accompanying webinar will contain, forward-looking statements"
Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.
Deferred compensation plan income financial

Ongoing Business Conditions

 

In the first quarter of 2026, MPS achieved record quarterly revenue of $804.2 million, 7.1% higher than the fourth quarter of 2025 and 26.1% higher than revenue in the first quarter of 2025.

 

Our quarterly performance was the result of our continued innovation, our consistent execution and the resilience of our diversified market strategy.

 

Q1 2026 highlights include:

 

 

Our Communications end market grew 33% sequentially on the strength of our power solutions for optical modules and switches.

 

  The pipeline for our Automotive and Enterprise Data end markets, including server, continued to accelerate as we won multiple new projects across customers and regions.

 

  We sampled our first high speed interface products for DDR5 at major customers.

 

  MPS continued to grow our capacity past our original $4B plan, with a new goal of reaching $6B in the near future.

 

We continue to adjust to the fluid geopolitical and macro-economic environment, but our diversified market strategy remains unchanged:

 

  MPS focuses on innovation and solving our customers’ most challenging problems.

 

  We consistently invest in new technologies that allow us to expand into new end markets and applications.

 

  We continue to expand and diversify our global supply chain allowing us to capture future growth opportunities, maintain supply stability, and rapidly adapt to market changes as they occur. 

 

“Our results demonstrate the strength of our diversified model and our continued success in transforming from a chip-only, semiconductor supplier to a full service, silicon-based solutions provider,” said Michael Hsing, CEO and founder of MPS.

Non-GAAP Financial Measures

 

This earnings commentary contains references to certain non-GAAP financial measures. Non-GAAP net income, non-GAAP net income per share, non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating income, non-GAAP other income, net, and non-GAAP income before income taxes differ from net income, net income per share, gross margin, operating expenses, operating income, other income, net, and income before income taxes determined in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”). Non-GAAP net income and non-GAAP net income per share exclude the effect of stock-based compensation and related expenses, which include stock-based compensation expense and employer payroll taxes in relation to the stock-based compensation, amortization of acquisition-related intangible assets, net deferred compensation plan income, and related tax effects. Non-GAAP gross margin excludes the effect of stock-based compensation and related expenses, amortization of acquisition-related intangible assets and deferred compensation plan income.

Non-GAAP operating expenses exclude the effect of stock-based compensation and related expenses, amortization of acquisition-related intangible assets and deferred compensation plan income. Non-GAAP operating income excludes the effect of stock-based compensation and related expenses, amortization of acquisition-related intangible assets and deferred compensation plan income. Non-GAAP other income, net excludes the effect of deferred compensation plan expense. Non-GAAP income before income taxes excludes the effect of stock-based compensation and related expenses, amortization of acquisition-related intangible assets and net deferred compensation plan income. Projected non-GAAP gross margin excludes the effect of stock-based compensation and related expenses, and amortization of acquisition-related intangible assets. Projected non-GAAP operating expenses exclude the effect of stock-based compensation and related expenses. These non-GAAP financial measures are not prepared in accordance with GAAP and should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. A schedule reconciling non-GAAP financial measures is included at the end of this press release. MPS utilizes both GAAP and non-GAAP financial measures to assess what it believes to be its core operating performance and to evaluate and manage its internal business and assist in making financial operating decisions. MPS believes that the inclusion of non-GAAP financial measures, together with GAAP measures, provides investors with an alternative presentation useful to investors’ understanding of MPS’s core operating results and trends. Additionally, MPS believes that the inclusion of non-GAAP measures, together with GAAP measures, provides investors with an additional dimension of comparability to similar companies. However, investors should be aware that non-GAAP financial measures utilized by other companies are not likely to be comparable in most cases to the non-GAAP financial measures used by MPS. See the GAAP to Non-GAAP reconciliations in the tables set forth below.
