Last Updated: Date November 6, 2026

This Cookie Policy (“Cookie Policy”) describes how Monolithic Power Systems, Inc., a Delaware corporation, and its subsidiaries and affiliates (collectively, “MPS,” “we,” “us,” or “our”) use cookies and other similar tracking technologies (collectively, “Cookies”) on the website located at https://www.monolithicpower.com and our related websites and forums, including partner.monolithicpower.com, forum.monolithicpower.com, www.monolithicpower.cn, forum.monolithicpower.cn, and www.axign.com (the website of our subsidiary, Axign B.V.) (collectively, the “Website”). Capitalized terms used but not defined in this Cookie Policy, including “Personal Information,” have the meanings given in our Privacy Policy. We use these technologies to enable Website features, analyze Website usage, deliver and measure advertising, and enhance the security of the Website and the services provided through it.

This Cookie Policy describes what Cookies are and how we use them, the categories of information collected through these technologies, third-party Cookies on our Website and how your data flows to them, options for managing Cookie preferences, your rights by jurisdiction, and how to contact us.

For more information on how MPS handles Personal Information, please see our:

Privacy Policy - which describes how we collect, use, disclose, and protect your Personal Information across all channels, not just Cookies. 1

1. What Are Cookies?

A cookie is a small text file that is stored by your web browser when you visit a website. Almost every website uses cookie technology. Cookies may store certain information such as your IP address, information about the content you view, information about the content you provide so that you do not have to re-enter it each time you visit our Website, and your preferences and settings. Cookies also help us provide you with customized content, speed navigation through our Website, and allow us to learn about your visit and your use of online services.

Our Website may also use other similar tracking technologies, such as web beacons, tracking pixels, and local storage, which function similarly to cookies. They help evaluate marketing effectiveness, load visual elements, and provide personalized content. References to “Cookies” in this Cookie Policy include these similar technologies unless otherwise stated.

2. How Long Do Cookies Last?

Session cookies: These are temporary and are deleted automatically when you close your browser. They are used for essential functions during your browsing session, such as maintaining your login state or remembering items in a shopping cart.

Persistent cookies: These remain on your device for a set period or until you delete them manually. They are used for functions that need to persist across sessions, such as remembering your preferences, recognizing returning visitors, and measuring long-term usage patterns.

3. What Cookies Does MPS Use?

We use four categories of Cookies on our Website. Each serves a different purpose and has a different consent requirement.

Necessary: These cookies are essential for the Website to function and cannot be switched off in our systems. They are usually only set in response to actions you take that amount to a request for services, such as setting your privacy preferences, logging in, or filling in forms. You can block them through your browser settings, but parts of the Website may not work. These cookies are not disabled by opting out of Cookies through our Cookie Preference Center.

Preferences: These cookies enable the Website to provide enhanced functionality and personalization by remembering your choices and preferences. They may be set by us or by third-party providers whose services we have added to our pages. Where required by applicable law, your consent is required. You can disable them through our Cookie Preference Center or your browser settings. The Website will still work, but some features may not remember your preferences.

Statistics: These cookies allow us to count visits and traffic sources so we can measure and improve the performance of our Website. They help us understand which pages are the most and least popular and how visitors navigate the Website. They may also be used, together with some Marketing cookies, to help show more relevant advertising across the web and to measure interactions with the advertisements we display. If you do not allow these cookies, we will not know when you have visited our Website and will not be able to monitor its performance. Where required by applicable law, your consent is required, and you can enable or disable these cookies through our Cookie Preference Center.

Marketing: These cookies may be set through our Website by our third-party advertising partners such as Google Ads, Google Display Network, Meta Pixel, and LinkedIn. They may be used by those companies to build a profile of your interests and show you relevant advertisements on other websites. They do not directly store Personal Information but are based on uniquely identifying your browser and internet device. If you do not allow these cookies, you will experience less targeted advertising. Where required by applicable law, your consent is required, and you can enable or disable these cookies through our Cookie Preference Center.

Cookies typically do not contain information that directly identifies you by name. However, Personal Information that we hold about you, such as your account information or order history, may be linked to the information stored in or obtained from Cookies. Where this linking occurs, we treat the combined data as Personal Information in accordance with our Privacy Policy (Privacy Policy). For a detailed list of each Cookie on our Website, including its name, provider, purpose, category, and duration, click Cookie Settings.

4. How Do Third-Party Cookies Share Data?

Some cookies on our Website are not set by MPS but by third parties that provide services to MPS, including advertising networks, social media platforms, and analytics providers. When these cookies are active, they may collect data about your browsing activity on our Website and share it with the third party that set them. Please refer to their privacy and cookie policies for more information. Some service providers we use include Google Analytics, Google Ads, Google Display Network, Meta, LinkedIn Ads, Bing Ads, Microsoft Clarity, Demandbase, Marketo, and Magento.

We encourage you to review each third party's privacy policy to understand how they process your data independently of MPS. Monolithic Power Systems, Inc. (“MPS USA”) is the controller of Personal Information collected through Cookies on the Website, including Personal Information collected on its behalf by service providers. Third-party advertising partners that set Marketing cookies may also act as independent controllers of the data they collect. For information about recipients beyond those involved in Cookie-based data collection, such as affiliated companies, distributors, professional advisors, and government authorities, please see our Privacy Policy (https://www.monolithicpower.com/en/privacy-policy).

5. How to Manage Your Cookie Preferences

You can manage, disable, or delete Cookies at any time using any of the following methods:

Our Cookie Preference Center: When you first visit our Website, you may be presented with a cookie banner allowing you to accept all Cookies, use necessary Cookies only, or adjust your preferences. You can update or withdraw your consent to non-essential Cookies at any time by clicking Cookie Settings or the Do Not Sell or Share My Personal Information link in the footer of our Website, which opens our Cookie Preference Center. Necessary Cookies cannot be disabled through the Cookie Preference Center because they are essential for the Website to function. You can block them through your browser settings, but parts of the Website may not work correctly.

Browser settings: Adjust your browser's cookie settings to block third-party cookies. This blocks all third-party cookies across all websites and may affect functionality on some sites.

Third Party Platform opt-outs: You can opt out of tracking by specific third parties using their own opt-out tools. Opting out through a specific platform stops that platform's tracking. Other third-party Cookies on our Website remain active unless you also disable them through our Cookie Preference Center or your browser settings.

Global Privacy Control (GPC): GPC is a browser-level signal that communicates your privacy preferences to every website you visit. You can enable GPC through your browser or a browser extension.

“Do Not Sell or Share My Personal Information”

If you are a California resident, or a resident of any U.S. state with a sale, sharing, or targeted advertising opt-out right, you can exercise your right by clicking the “Do Not Sell or Share My Personal Information” link in the footer of our Website, which opens our Cookie Preference Center, and toggling off Statistics and Marketing cookies; by enabling a Global Privacy Control signal; or by submitting our Privacy Rights Request Form (https://www.monolithicpower.com/contact/privacy-rights-request-form.html).

6. Data Retention

Cookies are stored for varying periods depending on their type and purpose. Session cookies are deleted when you close your browser, while persistent cookies remain on your device until they expire or are deleted by you. Persistent cookies (such as Marketing, Statistics, and Preferences cookies) are generally stored for 12 to 26 months and then automatically deleted.

Note: The retention periods above apply to the Cookies themselves as stored on your device. The retention of any Personal Information collected through Cookies and processed by MPS is described in our Privacy Policy (https://www.monolithicpower.com/en/privacy-policy). Retention by third parties is governed by their own privacy policies.

You can delete Cookies at any time through your browser settings, regardless of their stated retention period.

7. Does MPS Collect Children’s Data?

Our Website is not directed at children. We do not knowingly use Cookies to collect Personal Information from children under the age of 13 (or 16, where applicable by law). If we become aware that we have collected Personal Information from a child through Cookies, we will take steps to delete that data promptly. If you believe a child has provided us with Personal Information through our Website, please contact us at privacy@monolithicpower.com.

8. Updates to This Cookie Policy

We may update this Cookie Policy from time to time to reflect changes in our practices, technologies, legal requirements, or for other operational reasons.

When we make changes, we will:

• Update the "Last Updated" date at the top of this page.
• Where changes are material, such as adding new Cookie categories, new third-party providers, or changing the consent model, we will notify you through a prominent notice on our Website, by re-presenting the Cookie consent banner, or other similar means.
