Key Terms

non-gaap, stock-based compensation, operating cash flow, days of sales outstanding, +3 more
7 terms
non-gaap financial
"Non-GAAP gross margin for the first quarter of 2026 was 55.5%"
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
"The differences between non-GAAP operating expenses and GAAP operating expenses... are primarily stock-based compensation"
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.
operating cash flow financial
"For the first quarter of 2026, MPS generated operating cash flow of $250.3 million"
Operating cash flow is the amount of money a company earns from its main business activities, like selling products or services. It shows how well the company can generate cash to pay bills, invest in growth, or return money to shareholders. This figure helps investors understand if the company’s core operations are healthy and sustainable.
days of sales outstanding financial
"Accounts receivable... were $302.1 million, representing 34 days of sales outstanding"
Days of sales outstanding (DSO) measures the average number of days a company takes to collect payment after making a sale, calculated from outstanding customer invoices. Investors care because a higher DSO can signal slow cash flow or weak collection practices—like a business waiting longer to get paid—while a lower DSO shows faster cash conversion and healthier short-term liquidity, which affects a company’s ability to pay bills, invest, or return money to shareholders.
days of inventory financial
"Days of inventory of 157 days at the end of the first quarter of 2026"
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.
fully diluted shares outstanding financial
"There were 49.2 million fully diluted shares outstanding at the end of the first quarter of 2026"
Total number of shares that would exist if every outstanding option, warrant, convertible security and other instrument that can become stock were exercised or converted; it combines current shares with all potential shares. Investors use this figure to see the true size of the ownership pie and to judge per-share metrics like earnings or value per share, because potential extra shares can dilute each existing investor’s claim much like adding more slices reduces the size of each slice of a pie.
ddr5 technical
"We sampled our first high speed interface products for DDR5 at major customers"
DDR5 is the latest generation of high-speed volatile memory used as the short-term workspace for computers and servers, like a faster, larger desk where a processor keeps information it’s actively using. It matters to investors because upgrades to DDR5 drive demand across chip makers, computer builders and data-centre operators, affecting sales, pricing power and product cycles; companies that lead in DDR5 production or adoption can gain a competitive and financial edge.

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.

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.

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.
