Ongoing Business Conditions

In the second quarter of 2026, MPS achieved record quarterly revenue of $980.6 million, 21.9% higher than the first quarter of 2026 and 47.6% higher than revenue in the second quarter of 2025.

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

Q2 2026 highlights include:

•All end markets grew sequentially with Enterprise Data growing 45% as we continued to see strong, broad-based ordering patterns.

•We extended our capacity goal significantly beyond $6B to support future revenue growth and our transformation into a full solution provider.

•We received initial orders for high-speed DDR5 memory components which we expect to grow our SAM into next year.

•We began sampling High Voltage AC to DC products for 800V data center architectures as we expand beyond our current AI and server core power solutions.

•In our Automotive market, so far this year, we have shipped products for over 1500 new sockets as we increase our footprint in both ADAS and other applications within the vehicle.

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 open new end markets and applications.

•We continuously 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 solutions provider,” said Michael Hsing, CEO and founder of MPS.

Q2 2026 Revenue Results

MPS reported second quarter revenue of $980.6 million, 21.9% higher than the first quarter of 2026 and 47.6% higher than revenue in the second quarter of 2025. Compared with the first quarter of 2026, sales improved sequentially across all end markets.

In our Enterprise Data market, second quarter 2026 revenue of $380.6 million increased 44.8% from the first quarter of 2026. The sequential increase was driven by higher sales of our power management solutions for AI and server applications. Second quarter 2026 Enterprise Data revenue was up 164.3% year over year. Enterprise Data revenue represented 38.8% of our total second quarter 2026 revenue compared with 32.7% in the first quarter of 2026.

Second quarter 2026 Communications revenue of $131.5 million was up 18.0% from the first quarter of 2026 primarily as a result of higher sales of power solutions for optical modules and switches. Second quarter 2026 Communications revenue was up 78.3% year over year. Communications sales represented 13.4% of our total second quarter 2026 revenue compared with 13.9% the first quarter of 2026.

Second quarter 2026 Storage and Computing revenue of $199.8 million increased 14.6% from the first quarter of 2026 on higher sales for memory and storage power management solutions. Second quarter 2026 S

Item 2.02 Results of Operations and Financial Condition.

On August 1, 2024, Monolithic Power Systems, Inc. (the “Company”) issued a press release regarding its financial results for the quarter ended June 30, 2024. The press release is attached hereto as Exhibit 99.1 and is incorporated by reference herein.

Attached hereto as Exhibit 99.2 and incorporated by reference herein is financial information and commentary regarding results of the quarter ended June 30, 2024.

The information under Item 2.02 of this Current Report on Form 8-K and Exhibits 99.1 and 99.2 attached hereto are being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “1934 Act”), nor shall they be deemed incorporated by reference in any filing with the Securities and Exchange Commission under the 1934 Act or the Securities Act of 1933, as amended, except as shall be expressly set forth by specific reference in such filing.

Item 8.01 Other Events.

The Company has maintained a classified board of directors (the “Board”) since its initial public offering in 2004. At the Company’s 2024 annual meeting of stockholders (the “2024 Annual Meeting”), a majority of the Company’s stockholders voted, on an advisory basis, in favor of a stockholder proposal to declassify the Company’s Board (the “Proposal”).

The Board has extensively discussed the merits of a classified Board, as well as the results of the stockholder vote on the Proposal. As part of the 2024 Annual Meeting, the Company also conducted significant outreach and engagement with its major stockholders and discussed various matters, including the Proposal. While the Board believes that the Company’s stockholders have benefited from having a classified Board, the Board determined on July 30, 2024 that, given the results of the Proposal, it is advisable to declassify the Board over a period of time.

The Board intends to approve and recommend to the Company’s stockholders at the 2025 annual meeting of stockholders an amendment to the Company’s Certificate of Incorporation to declassify the Board such that: (i) each class of directors will have one more election in which it is elected for a three-year term; (ii) at the Company’s 2028 annual meeting of stockholders, the Class III directors will be elected to a two-year term; (iii) at the Company’s 2029 annual meeting of stockholders, the Class I directors will be elected to a one-year term; and (iv) commencing with the Company’s 2030 annual meeting of stockholders, all directors will be elected to one-year terms at each annual meeting of stockholders.

The Board believes the six-year plan outlined above is optimal for the following reasons:

●

Continuity and Stability: The Company takes a long-term view of its business strategy and maximization of stockholder value.  A six-year plan will offer each class of directors one final three-year
