MPWR 8-K Current Reports

Monolithic Power Systems 8-K Report, Corporate Update (Sep 10, 2026)

Monolithic Power Systems (MPWR) filed a brief Form 8-K on September 10, 2026, to disclose that it issued a press release announcing a third-quarter 2026 cash dividend of $2.00 per common share. The dividend is payable to stockholders of record as of the close of business on September 30, 2026, with payment scheduled for October 15, 2026. The filing is routine in nature under Item 8.01 (Other Events) and contains no financial results, guidance, or material operating developments. For investors, the key takeaway is the continued commitment to shareholder returns through a regular quarterly dividend. The filing does not disclose the total cash cost of the dividend, the dividend's yield relative to the share price, or whether the payout is changing from prior quarters. Those details would need to be cross-referenced against the company's prior dividend history, share count, and recent 10-Q disclosures. The 8-K also notes that MPS operates across the U.S., Europe, and Asia without a single headquarters location, and that the Schaffhausen, Switzerland dateline in the press release reflects the issuing location. This is a standard disclosure for the company and does not signal any change in corporate structure or governance.

Monolithic Power Systems 8-K Report, Financial Results (Jul 30, 2026)

Monolithic Power Systems (MPWR) reported record second-quarter 2026 revenue of $980.6 million, up 21.9% sequentially and 47.6% year over year. Every end market grew sequentially, led by Enterprise Data, which rose 44.8% quarter over quarter to $380.6 million and now represents 38.8% of revenue. GAAP net income was $257.3 million ($5.22 per diluted share), and non-GAAP net income was $320.1 million ($6.50 per diluted share). GAAP operating margin expanded to 31.0% from 30.0% in Q1 and 24.8% a year earlier, and non-GAAP operating margin reached 37.5%. Gross margin was essentially flat at 55.2% GAAP and 55.6% non-GAAP. The third-quarter outlook calls for revenue of $1,140 million to $1,160 million, which implies roughly 16% to 18% sequential growth at the midpoint of the range. Guidance also calls for GAAP gross margin of 55.2% to 55.8% and a 15% non-GAAP tax rate for 2026. The Board added $500 million to the stock repurchase authorization, bringing the total to $1 billion. Management highlighted new opportunities, including initial orders for high-speed DDR5 memory components, sampling of high-voltage AC-to-DC products for 800V data center architectures, and more than 1,500 new automotive sockets shipped year to date. Balance sheet liquidity is solid, with $1,413.8 million in cash and short-term investments. Inventory rose to $675.8 million, though days of inventory fell to 140 from 157. Investors should weigh the strong growth against concentration in AI and data center demand, which is highly cyclical and dependent on a few large customers. The filing also notes a material weakness in internal control that management is working to remediate, which is a governance item to monitor. The filing is furnished under Item 2.02 and is not deemed filed under the Exchange Act.

Monolithic Power Systems 8-K Report, Shareholder Vote Results (Jun 12, 2026)

Monolithic Power Systems (MPWR) filed an 8-K on June 12, 2026 covering three routine items: the results of its June 11, 2026 annual meeting, and a second-quarter cash dividend. The filing contains no earnings, guidance, or operational data, so investors should read it mainly as a confirmation of shareholder support and a dividend declaration. Stockholders re-elected two Class I directors, Victor K. Lee and Jeff Zhou, to three-year terms ending at the 2029 annual meeting. Lee received about 89.8% of votes cast for, with about 10.2% withheld. Zhou received about 94.0% for and 6.0% withheld, so Lee drew noticeably more opposition. Stockholders also ratified Ernst & Young LLP as auditor for 2026 with about 99.8% of votes cast in favor, and approved the 2025 named executive officer compensation on an advisory basis with about 96.8% of for-and-against votes in favor. The company declared a $2.00 per share cash dividend, payable July 15, 2026 to stockholders of record at the close of business on June 30, 2026. The filing does not state total shares outstanding or the aggregate payout, and it does not say whether this dividend is a regular recurring payment, so investors should check prior disclosures for those details.

Monolithic Power Systems 8-K Report, Financial Results (Apr 30, 2026)

Monolithic Power Systems (MPS) reported record first-quarter 2026 revenue of $804.2 million, up 7.1% sequentially and 26.1% year over year, driven primarily by Enterprise Data (up 12.6% QoQ and nearly doubled YoY to $262.8 million) and Communications (up 33.1% QoQ to $111.5 million, on optical modules and switches). GAAP operating margin expanded to 30.0% from 26.6% in Q4 2025, with GAAP diluted EPS of $3.92 versus $3.49 a quarter earlier; non-GAAP diluted EPS was $5.10. Gross margin held steady at roughly 55%, while GAAP operating expenses fell 4.9% sequentially on lower stock-based compensation ($48.5 million versus $66.9 million). Balance sheet and cash generation were strong. Operating cash flow rose to $250.3 million from $104.9 million, and cash plus short-term investments reached $1,367.1 million. However, working capital metrics warrant monitoring: accounts receivable days rose to 34 from 31, and internal inventories climbed to $619.2 million (157 days of current-quarter revenue, up from 153). Management stated that days of inventory on next-quarter revenue improved to 140 days. For Q2 2026, management guided revenue of $890 million to $910 million, implying continued sequential growth, with non-GAAP gross margin of 55.3% to 55.9% and non-GAAP operating expenses of $167 million to $171 million. The filing also notes that the company is working to remediate a material weakness in internal controls, and the Form 8-K was signed by Robert Dean as Interim Chief Financial Officer, a leadership detail investors should watch. The results are furnished under Item 2.02 rather than filed, and the company disclosed that it has no single headquarters location.

Monolithic Power Systems 8-K Report, Financial Restatement (Feb 27, 2026)

Monolithic Power Systems, Inc. (MPWR) has filed an 8-K report on February 27, 2026, announcing that its previously issued financial statements for the fiscal year ended December 31, 2024, and interim periods in 2025, should no longer be relied upon. This is due to an unintentional error related to the accounting for deferred income taxes associated with a foreign jurisdiction's tax incentive. The company emphasizes that this is a non-cash error and does not impact key operational metrics such as revenue, non-GAAP gross margin, non-GAAP operating expenses, non-GAAP net income, and non-GAAP diluted net income per share. The restatement primarily affects the "income tax benefit, net" and "deferred income taxes," resulting in a decrease of $195 million for the year ended December 31, 2024. The company will file its 2025 Form 10-K shortly to include these restated financials.

Monolithic Power Systems 8-K Report, Financial Results (Feb 5, 2026)

Monolithic Power Systems (MPWR) reported record fourth-quarter and full-year 2025 results. Q4 revenue rose 20.8% year over year to $751.2 million (up 1.9% sequentially), and full-year revenue grew 26.4% to $2.79 billion, marking the company's 14th consecutive year of revenue growth. GAAP gross margin was steady at 55.2% and non-GAAP gross margin at 55.5%. GAAP operating income was $199.9 million for the quarter, while non-GAAP operating income reached $269.0 million. Diluted GAAP EPS was $3.46 versus $29.88 a year earlier, but that comparison is distorted by a $1.285 billion one-time foreign tax benefit recognized in Q4 2024; on a non-GAAP basis, Q4 diluted EPS rose 17.1% to $4.79. Growth was led by Storage and Computing (+46% for the year) and Automotive (+43%), while Enterprise Data declined 2% for the year, though it rebounded sequentially in Q4. The company guided Q1 2026 revenue to $770–790 million, implying continued sequential growth, with non-GAAP gross margin of 55.2%–55.8% and non-GAAP operating expenses of $156–160 million. It also raised its quarterly cash dividend 28%, from $1.56 to $2.00 per share, payable April 15, 2026. Balance sheet metrics warrant monitoring: inventory rose to $564.6 million (153 days of current-quarter revenue, up 14 days sequentially) and operating cash flow fell to $104.9 million from $239.3 million in Q3. Leadership news also accompanied the release. CFO Bernie Blegen will retire after the 2025 Form 10-K is issued, and Corporate Controller Rob Dean will serve as interim CFO. The transition is orderly, with Blegen staying on to assist, but a permanent successor has not yet been named.

Monolithic Power Systems 8-K Report, Corporate Update (Dec 12, 2025)

Monolithic Power Systems (MPWR) filed a brief Form 8-K on December 12, 2025 under Item 8.01 (Other Events) to announce its fourth quarter 2025 cash dividend of $1.56 per share. The dividend is payable to stockholders of record as of the close of business on December 31, 2025, with payment scheduled for January 15, 2026. The announcement is contained in a press release furnished as Exhibit 99.1. The filing contains no financial results, guidance, or material operational developments. Its significance for investors is primarily a confirmation of the company's ongoing shareholder return policy, since the dividend is a meaningful, regular payment rather than a one-time distribution. Investors should note that the per-share amount is disclosed here without any accompanying commentary on the company's cash position, earnings, or payout outlook. For investors evaluating the stock, the key practical item is the record date: shares must be held as of December 31, 2025 to receive the payment. Because this is a routine quarterly declaration, the filing should be read as a reaffirmation of the existing dividend program rather than a signal of a change in capital allocation. Investors seeking the company's financial performance should refer to its most recent Form 10-K and 10-Q filings.

Monolithic Power Systems 8-K Report, Bylaw Amendment (Nov 21, 2025)

Monolithic Power Systems, Inc. (MPWR) has filed an 8-K report primarily detailing an amendment to its corporate bylaws. Effective November 19, 2025, the Board of Directors has reduced the ownership threshold required for stockholders to call a special meeting from 30% to 25% of outstanding voting shares. This decision was influenced by the outcome of the 2025 annual meeting, where a non-binding proposal to lower the threshold to 10% was approved by stockholders, and feedback from a majority of the company's top ten stockholders who supported a threshold higher than 10% but lower than the previous 30% requirement. This bylaw change reflects the company's responsiveness to shareholder sentiment and a review of corporate governance practices among its peers. While not a financial event, this amendment could impact future corporate actions and shareholder engagement by making it more feasible for a significant block of shareholders to convene special meetings to discuss matters relevant to the company's direction. Investors should monitor any subsequent actions or proposals that may arise from this adjustment to the special meeting threshold.

Monolithic Power Systems 8-K Report, Financial Results (Oct 30, 2025)

Monolithic Power Systems (MPWR) reported record third-quarter 2025 results, with revenue of $737.2 million, up 10.9% sequentially from $664.6 million and up 18.9% year over year from $620.1 million. GAAP gross margin was 55.1% (flat sequentially, down 0.3 points year over year), while non-GAAP gross margin was 55.5%. GAAP operating income rose to $195.2 million (26.5% operating margin), and GAAP diluted EPS was $3.71, up roughly 26% from $2.95 a year earlier. Non-GAAP diluted EPS was $4.73, up 16.5% year over year and 12.4% sequentially. Growth was broad-based, with year-over-year increases in every end market, led by Storage and Computing (+29.6%), Automotive (+36.1%), and Industrial (+25.7%); Enterprise Data rose sharply sequentially (+33%) on AI-related power management demand. The quarter also showed some operating pressure. GAAP operating expenses grew 17.6% year over year to $211.0 million, and non-GAAP operating margin of 35.4% was down 0.2 points year over year despite the higher revenue. Accounts receivable rose to 30 days of sales outstanding from 27 days in Q2, and inventories increased modestly to $505.7 million. Cash and short-term investments reached $1.27 billion, and operating cash flow was $239.3 million. For Q4 2025, management guided revenue to $730–750 million, GAAP gross margin to 54.9%–55.5%, and non-GAAP gross margin to 55.2%–55.8%. Non-GAAP operating expenses are expected at $145.5–149.5 million, with a 15% non-GAAP tax rate and 48.5–48.9 million fully diluted shares. The guidance implies a roughly flat-to-down sequential revenue range at the midpoint, which investors will weigh against the strong Q3 print.

Monolithic Power Systems 8-K Report, Financial Results (Jul 31, 2025)

Monolithic Power Systems (MPWR) reported record second-quarter 2025 results, with revenue of $664.6 million, up 4.2% sequentially from $637.6 million and up 31.0% year over year from $507.4 million. GAAP gross margin was 55.1% (vs. 55.3% a year ago) and non-GAAP gross margin was 55.5% (vs. 55.7%). Growth was led by Storage and Computing (up 70.0% YoY to $195.3 million) and Automotive (up 66.4% YoY to $145.1 million), while Enterprise Data declined 23.1% YoY to $144.0 million. Management noted initial shipments of power solutions for customers' new ASIC-based AI products had begun. Profitability improved on an operating basis. GAAP operating income rose 41% YoY to $164.8 million, though GAAP operating margin compressed sequentially to 24.8% from 26.5% as GAAP operating expenses rose 9.1% QoQ to $201.3 million, driven largely by stock-based compensation of $60.3 million. Non-GAAP operating income was $231.2 million, and non-GAAP diluted EPS was $4.21 (up 32.8% YoY), versus GAAP diluted EPS of $2.78, which was flat sequentially. Cash, cash equivalents and short-term investments reached $1.146 billion, operating cash flow was $237.6 million, and inventory rose to $490.6 million (150 days of current-quarter revenue).

Investors will likely focus on the pace of AI-related ramps, the sequential margin and opex trends, and inventory levels relative to demand.

Monolithic Power Systems 8-K Report, Bylaw Amendment (Jun 16, 2025)

Monolithic Power Systems (MPWR) filed this 8-K to report governance changes and routine shareholder actions following its 2025 annual meeting on June 12, 2025. The most significant change is the stockholder-approved amendment and restatement of the Certificate of Incorporation, along with new Amended and Restated Bylaws, which phase out the classified (staggered) Board over a period running through the 2030 annual meeting. Directors will be elected for three-year terms through 2027, two-year terms in 2028, one-year terms in 2029, and fully annual elections from 2030. Until the Board is fully declassified, directors may be removed only for cause. Shareholders elected three Class III directors (Herbert Chang, Michael Hsing, and Carintia Martinez), ratified Ernst & Young LLP as auditor for 2025, and approved on an advisory basis the 2024 compensation of named executive officers. The meeting also surfaced shareholder dissatisfaction in one area: a non-binding stockholder proposal to allow shareholders to call special meetings passed with 24.6 million votes for versus 17.6 million against, a much narrower margin than the other proposals. Support for the directors was strong overall, though Michael Hsing received notably more support than Herbert Chang and Carintia Martinez. Votes for the executive compensation advisory proposal were solid, with roughly 40.7 million for and 1.4 million against. From a financial standpoint, the filing's only disclosed economic item is a declared second-quarter 2025 cash dividend of $1.56 per share, with a record date of June 30, 2025 and payment on July 15, 2025. This filing does not include new financial results, guidance, or capital allocation changes beyond the dividend.

Monolithic Power Systems 8-K Report, Financial Results (May 1, 2025)

Monolithic Power Systems (MPWR) reported first-quarter 2025 results on May 1, 2025, with revenue of $637.6 million, up 2.6% sequentially and 39.2% year over year, setting a new quarterly record. GAAP net income was $133.8 million ($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 million, 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 million, 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.

Monolithic Power Systems, Inc. (MPWR) has filed an 8-K report on March 26, 2025, announcing an amendment to its corporate governance. The key development is the adoption of Amended and Restated Bylaws, effective immediately, which introduce a mechanism for stockholders to call special meetings. This change empowers shareholders by granting them the right to convene a special meeting if they collectively hold at least 30% of the outstanding common stock entitled to vote, provided they have held these shares for at least one year. The bylaws outline the specific procedural requirements and disclosures necessary for stockholders to exercise this right. This move could increase shareholder engagement and influence on corporate matters.

Regulation FDExhibits & Filings

Monolithic Power Systems 8-K Report, Regulation FD Disclosure (Mar 20, 2025)

On March 20, 2025, Monolithic Power Systems (MPWR) filed an 8-K under Regulation FD (Item 7.01) to disclose two items: an Analyst Day webcast at 9:00 am Pacific Time, where management is expected to discuss corporate strategy, business and product updates, and financial metrics, and a press release updating its first-quarter 2025 financial guidance. The filing states that the Analyst Day materials (Exhibit 99.1) and the guidance release (Exhibit 99.2) are furnished, not filed, so they are not subject to Section 18 liability. The filing contains no financial results and no new long-term targets beyond what the presentation may contain. The key change is a guidance raise. First-quarter revenue guidance moved up to $630.0 million to $640.0 million from $610.0 million to $630.0 million, an increase of $20.0 million at the low end and $10.0 million at the high end, implying a narrower range and a higher midpoint of about $635 million versus $620 million previously. Guidance for GAAP operating expenses rose to $184.9 million to $190.9 million from $180.2 million to $186.2 million, and non-GAAP operating expenses rose to $131.6 million to $135.6 million from $126.9 million to $130.9 million. The company attributes no specific cause to the expense increase in the release, and the stock-based compensation adjustment is unchanged at $53.3 million to $55.3 million. For investors, the revenue raise is the main signal, since it suggests stronger-than-expected demand entering the first quarter. The higher expense outlook partly offsets this, so the net effect on profitability depends on the mix of spending. Full first-quarter results and second-quarter guidance are due at the end of April or beginning of May 2025, and the Analyst Day commentary may provide more context on the company's multi-year strategy.

Monolithic Power Systems 8-K Report, Financial Results (Feb 6, 2025)

Monolithic Power Systems (MPWR) reported record fourth-quarter and full-year 2024 results, with full-year revenue of $2.21 billion, up 21.2% year over year, marking its 13th consecutive year of revenue growth. Q4 revenue reached $621.7 million, essentially flat sequentially (+0.2%) and up 36.9% from Q4 2023. Growth was led by Enterprise Data, which more than doubled for the year (+121.7% to $716.2 million) on demand for AI and server power solutions. Non-GAAP gross margin held at 55.8% in Q4, and non-GAAP operating margin for the quarter was about 35.5%. GAAP operating margin for the full year declined to 24.4% from 26.5%, and GAAP gross margin fell to 55.3% from 56.1%. GAAP net income of $1.79 billion for the year, and $1.45 billion for Q4, is inflated by a one-time, non-cash recognition of a $1.3 billion tax benefit tied to a foreign subsidiary. Excluding that item, non-GAAP net income was $689.8 million for the year ($14.12 per diluted share) and $198.4 million for Q4 ($4.09 per diluted share). Q4 non-GAAP EPS was roughly flat sequentially. Investors should focus on the non-GAAP figures for underlying profitability, while recognizing that the deferred tax asset increase substantially boosts book equity and the balance sheet. Capital return remains a priority. The quarterly dividend rises 25% to $1.56 per share from $1.25, payable April 15, 2025. The board also authorized a new $500 million share repurchase program running through February 4, 2028, following the $640 million program that was fully executed in Q4 2024. Cash, cash equivalents and short-term investments fell to $862.9 million from $1.46 billion in Q3, largely because of Q4 buybacks. For Q1 2025, management guided revenue to $610–$630 million, non-GAAP gross margin to 55.4%–56.0%, and non-GAAP operating expenses to $126.9–$130.9 million, with a 15% non-GAAP tax rate.

It is a routine capital return disclosure, and it does not include Item 2.02 results of operations, so the financial performance of the company is not discussed here. Investors should treat the filing primarily as confirmation of a quarterly dividend policy rather than as a signal about business performance.

Monolithic Power Systems 8-K Report, Financial Results (Oct 30, 2024)

Monolithic Power Systems (MPWR) reported record third-quarter 2024 revenue of $620.1 million, up 22.2% sequentially and 30.6% year over year, driven by a sharp rebound in Enterprise Data (up 86.4% YoY to $184.5 million), Communications (up 53.6% YoY) and Automotive (up 17.0% YoY). GAAP gross margin was 55.4% and non-GAAP gross margin 55.8%, both roughly flat year over year. GAAP operating income rose 21% to $164.0 million, but GAAP operating expenses grew 40% YoY to $179.4 million, largely reflecting stock-based compensation of $52.4 million, which is a significant drag on GAAP profitability. GAAP diluted EPS was $2.95 versus $2.48 a year earlier, and non-GAAP diluted EPS was $4.06 versus $3.08. Cash, equivalents and short-term investments reached $1.46 billion, and operating cash flow was $231.7 million, up from $141.0 million in the prior quarter. Days sales outstanding fell to 24 from 28 and days of inventory fell to 140 from 171 on a current-quarter revenue basis, indicating improved working capital efficiency. The company is guiding fourth-quarter revenue to $600-620 million, implying a sequential change roughly flat to modestly down at the midpoint, with GAAP gross margin of 55.2%-55.8% and GAAP operating expenses of $170.7-174.7 million. For investors, the key takeaways are the strong demand recovery in Enterprise Data and Automotive, improved cash generation and working capital metrics, and the continued heavy stock-based compensation burden that widens the gap between GAAP and non-GAAP results. The Q4 outlook suggests revenue may plateau near current record levels, so the sustainability of the Q3 surge is the central question. Note that the Enterprise Data gain is largely attributed to ramps and demand that may be lumpy, and the company's guidance is forward-looking and subject to the risks described in its safe harbor statement.

Monolithic Power Systems 8-K Report, Corporate Update (Sep 13, 2024)

Monolithic Power Systems (Nasdaq: MPWR) filed a Form 8-K on September 13, 2024 to announce its regular third quarter 2024 cash dividend of $1.25 per common share. Stockholders of record as of the close of business on September 30, 2024 are eligible, and payment is scheduled for October 15, 2024. The filing is administrative in nature under Item 8.01 (Other Events), with no new financial results, guidance, or material operational developments disclosed. For investors, the key takeaway is the continuation of MPS's shareholder return program. A $1.25 quarterly dividend represents a consistent, recurring capital return and signals management's confidence in ongoing cash generation. Investors seeking to capture this payment must hold shares in their name or in street name by the September 30 record date. Because the record date is the reference point for eligibility, the ex-dividend date (typically set one business day before the record date under standard Nasdaq/T+1 settlement conventions) is the practical cutoff for purchases. The filing itself contains no information on fundamentals, pipeline, or outlook. Investors should therefore treat it as a routine capital-return notice and refer to the company's most recent Form 10-K and 10-Q filings, along with its earnings materials, for performance context. The press release includes standard forward-looking statement cautions tied to those filings.

Monolithic Power Systems 8-K Report, Financial Results (Aug 1, 2024)

Monolithic Power Systems (MPWR) reported record second-quarter 2024 revenue of $507.4 million, up 10.8% sequentially and 15.0% year over year, exceeding the high end of its own outlook. The growth was driven primarily by Enterprise Data, where revenue more than tripled year over year to $187.2 million (36.9% of revenue) on server AI power demand, offsetting continued weakness in Consumer (down 35.3% YoY), Industrial (down 35.0%), Automotive (down 16.5%) and Storage & Computing (down 7.7%). GAAP gross margin was 55.3% (down 0.8 points YoY), while GAAP operating margin was 23.0%, down 2.5 points YoY because GAAP operating expenses rose 21.2% to $164.0 million, largely due to stock-based compensation that reached $52.3 million in the quarter. GAAP diluted EPS was $2.05 versus $2.04 a year ago; non-GAAP diluted EPS was $3.17, up 12.4%. Cash, equivalents and investments reached $1.31 billion, and accounts receivable days fell to 28 from 39 in the prior quarter. Operating cash flow, however, dropped to $141.0 million from $248.0 million in Q1, and internal inventory rose to $426.8 million. For Q3 2024, management guided to revenue of $590–610 million and GAAP gross margin of 55.2%–55.8%, implying continued sequential growth that depends heavily on the durability of AI-related demand. Separately, the Board, after a majority of stockholders backed a non-binding (advisory) shareholder proposal at the 2024 annual meeting, determined on July 30, 2024 to declassify the board over a six-year phase-in, with all directors standing for annual election beginning at the 2030 annual meeting, subject to a Certificate of Incorporation amendment to be recommended at the 2025 annual meeting. This is a governance change that may be viewed favorably by shareholders advocating for greater accountability.

Monolithic Power Systems 8-K Report, Shareholder Vote Results (Jun 14, 2024)

Monolithic Power Systems (MPWR) filed this 8-K to report the outcomes of its 2024 Annual Meeting of Stockholders, held June 13, 2024, and to announce its second quarter 2024 cash dividend of $1.25 per share. The filing is largely procedural, but it contains a few items investors may weigh: all three Class II director nominees (Eugen Elmiger, Eileen Wynne, Jeff Zhou) were elected to three-year terms ending at the 2027 annual meeting, though Elmiger drew the most withholding votes (about 8.4 million, roughly 20% of votes cast). Stockholders also ratified Ernst & Young LLP as the independent auditor for fiscal 2024 with overwhelming support, approximately 44.8 million votes for against fewer than 19,000 against. The most notable governance signal is the non-binding stockholder proposal to elect all directors annually, which passed with about 35.5 million votes for versus 7.2 million against. Because it was advisory, the board is not legally required to act on it, but majority support for declassifying the board is a signal that shareholders may push for the change. Say-on-pay, the advisory vote on 2023 executive compensation, also passed, with about 41.4 million votes for against roughly 1.1 million against, indicating broad investor support for current pay practices. On the capital return side, the board declared a $1.25 per share quarterly dividend payable July 15, 2024 to holders of record as of June 28, 2024. The filing does not disclose financial results, guidance, or changes to the company's business, so its investment implications rest mainly on the governance votes and the continued dividend.

Monolithic Power Systems 8-K Report, Financial Results (May 1, 2024)

Monolithic Power Systems (MPWR) reported first-quarter 2024 results that were essentially flat sequentially and modestly up year over year on the top line. Revenue was $457.9 million, up 0.9% from Q4 2023 and 1.5% from Q1 2023, driven by a sharp rebound in Enterprise Data (up 217% year over year to $149.7 million, now 32.7% of revenue) that offset steep declines in Automotive, Communications, Consumer, Industrial and Storage & Computing. GAAP gross margin was 55.1% (down 2.3 points year over year) and GAAP operating margin fell to 20.9% from 27.6%, as GAAP operating expenses rose 16.7% year over year to $157.0 million, largely due to stock-based compensation of $51.8 million. GAAP diluted EPS was $1.89 versus $2.26 a year earlier, while non-GAAP diluted EPS was $2.81 versus $3.00. Management's tone was cautiously constructive. CEO Michael Hsing said results improved consistently through the quarter but that the company remains cautious about second-half 2024 business conditions, and the company noted that customer engagement and its design-win pipeline remain strong. Operating cash flow improved to approximately $248.0 million from $153.3 million in Q4 2023, and cash, cash equivalents and investments rose to about $1.29 billion. Inventory was $396.0 million, with days of inventory at 175 days on current-quarter revenue (down to 165 days on next-quarter projected revenue), which management highlighted as disciplined inventory management ahead of potential market upturns. For Q2 2024, MPS guided to revenue of $480 million to $500 million, GAAP gross margin of 55.1% to 55.7%, non-GAAP gross margin of 55.4% to 56.0%, GAAP operating expenses of $147.9 million to $151.9 million, and a fully diluted share count of 48.8 to 49.2 million. The revenue guidance implies roughly 5% to 9% sequential growth at the midpoint-to-high end, signaling expected near-term momentum, though the lack of visibility into the second half of 2024 remains the key uncertainty for investors.

Monolithic Power Systems 8-K Report, Financial Results (Feb 7, 2024)

Monolithic Power Systems (MPWR) reported fourth-quarter 2023 revenue of $454.0 million, down 4.4% sequentially from $474.9 million and down 1.3% year over year from $460.0 million. GAAP gross margin fell to 55.3% from 58.2% a year earlier, and GAAP net income was $96.9 million, or $1.98 per diluted share, versus $2.45 a year earlier. For full-year 2023, revenue grew 1.5% to $1,821.1 million, but GAAP net income declined to $427.4 million ($8.76 per diluted share) from $437.7 million ($9.05), and GAAP gross margin compressed to 56.1% from 58.4%. Non-GAAP operating income for the year was $641.1 million versus $680.9 million in 2022, reflecting margin pressure and lower operating leverage. Management stated it remains cautious about near-term business conditions while maintaining its long-term growth strategy. The mix shifted meaningfully during 2023. Enterprise Data (up about 28% for the year, and more than 88% year over year in Q4) and Automotive (up about 32% for the year) grew strongly, offsetting declines in Consumer (down about 27%), Communications (down about 19%), and Industrial (down about 21%). Storage and Computing also grew about 9% for the year. The balance sheet remains strong, with cash and short-term investments totaling roughly $1.1 billion at year end, up from about $738 million, and total stockholders' equity of $2.05 billion. The company also raised its quarterly cash dividend 25%, from $1.00 to $1.25 per share, payable April 15, 2024 to holders of record on March 29, 2024. For Q1 2024, guidance calls for revenue of $437.0 million to $457.0 million and non-GAAP gross margin of 55.4% to 56.0%, with non-GAAP operating expenses of $101.8 million to $103.8 million. The guidance midpoint implies flat to modestly lower sequential revenue, so investors will likely focus on whether demand in Enterprise Data and Automotive can sustain growth while other end markets stabilize.

Monolithic Power Systems 8-K Report, Corporate Update (Dec 15, 2023)

Monolithic Power Systems (MPWR) filed a Form 8-K on December 15, 2023 to announce its fourth quarter 2023 cash dividend of $1.00 per common share. Stockholders of record as of the close of business on December 29, 2023 will be eligible to receive the dividend, which is scheduled to be paid on January 15, 2024. The filing was furnished under Item 8.01 (Other Events), with the full press release attached as Exhibit 99.1. The filing contains no financial results, guidance, or operational updates. From an investor standpoint, the key data points are the per-share amount, the record date, and the payment date. A $1.00 quarterly dividend is a routine capital return action and reflects management's continued commitment to returning cash to shareholders. Investors seeking to capture this dividend must own the stock by the record date; under standard T+1 settlement, that generally means purchasing shares at least one business day before December 29, 2023 (ex-dividend date typically falls on the same day as the record date under T+1 rules). The 8-K itself does not disclose the company's financial performance, outlook, or any changes to its capital return policy. Investors should refer to the company's Form 10-K and Form 10-Q filings, as well as earnings releases, for information on profitability, cash flow, and forward-looking business trends.

Monolithic Power Systems 8-K Report, Financial Results (Oct 30, 2023)

Monolithic Power Systems (MPWR) reported third-quarter 2023 revenue of $474.9 million, up 7.6% sequentially from $441.1 million but down 4.1% year over year from $495.4 million. GAAP gross margin compressed to 55.5% from 58.7% a year earlier, and GAAP diluted EPS was $2.48 versus $2.57. Non-GAAP diluted EPS was $3.08 versus $3.53. For the nine months, revenue grew 2.5% to $1,367.1 million, driven by strong Automotive growth (up roughly 50%), while Consumer, Communications, and Industrial declined. Management said short-term visibility remains limited, consistent with the prior quarter. Fourth-quarter 2023 guidance calls for revenue of $442.0 million to $462.0 million, implying a sequential change of roughly -3% to +5% and a year-over-year decline at the midpoint. GAAP gross margin is guided to 55.2% to 55.8%, and total stock-based compensation to $32.2 million to $34.2 million. Diluted shares are expected at 48.7 to 49.1 million. Alongside results, the Board approved a new $640 million share repurchase program expiring October 29, 2026. Repurchases will be funded from working capital and cash repatriated from the Bermuda subsidiary. As of September 30, 2023, the company held roughly $1.0 billion in cash, equivalents, and investments. The program does not obligate purchases and can be suspended at any time. Investors should weigh the buyback against the margin compression and limited near-term visibility.

Monolithic Power Systems 8-K Report, Financial Results (Jul 31, 2023)

Monolithic Power Systems (MPWR) reported second-quarter 2023 revenue of $441.1 million, down 2.2% sequentially and 4.3% year over year, as weakness in consumer and enterprise data offset a strong rebound in automotive. GAAP gross margin fell to 56.1% from 58.8% a year earlier, and GAAP operating income declined about 21% to $112.3 million. GAAP diluted EPS was $2.04 versus $2.37, and non-GAAP diluted EPS was $2.82 versus $3.25. For the first half, revenue grew 6.4% to $892.2 million, driven by automotive, which nearly doubled to $209.7 million. The quarter's mix shift is the central story. Automotive revenue rose 71% year over year to $104.4 million, while consumer fell 33% to $65.2 million and enterprise data fell 26% to $48.0 million. Industrial and communications were also down year over year. Management guided third-quarter revenue to $464.0–484.0 million, a midpoint of $474 million that implies roughly 7.5% sequential growth. Guided GAAP gross margin of 55.5–56.1% and GAAP operating expenses of $129.4–133.4 million point to continued margin pressure, though it is not yet clear how much of the revenue recovery will be sustained. The balance sheet remains strong, with $940.5 million in cash and short-term investments against total liabilities of $381.5 million and stockholders' equity of $1.84 billion. Inventory declined to $427.4 million from $447.3 million at year-end 2022, and accounts receivable fell modestly. Investors will likely focus on whether automotive growth can offset cyclical softness in consumer and enterprise data, and on the trajectory of gross margins as utilization and pricing evolve.

Monolithic Power Systems 8-K Report, Executive Changes (Jun 15, 2023)

Monolithic Power Systems (MPWR) filed this 8-K on June 15, 2023, to report results from its 2023 Annual Meeting of Stockholders, to disclose an amended employee stock purchase plan, and to announce a $1.00 per share quarterly dividend. The most notable item for investors is the advisory say-on-pay vote on 2022 executive compensation. Roughly 43% of votes cast (18.5 million against versus 24.5 million for) opposed the pay package, a meaningful level of shareholder dissent. The company said it will hold annual advisory pay votes going forward, reflecting strong support for that frequency (about 42.8 million votes for annual). The amended 2004 Employee Stock Purchase Plan (Amended 2004 ESPP) was approved by stockholders and takes effect August 16, 2023, after the current plan's final purchase period ends on August 15, 2023. It has a 15-year term through August 16, 2038, and removes the evergreen share-replenishment provision in favor of a fixed authorization of 4.4 million shares. It also broadens eligibility to include part-time and seasonal common-law employees of the company and participating subsidiaries. Investors should monitor future share issuance and dilution, since a fixed pool is more predictable than an evergreen structure. Shareholders re-elected Class I directors Victor K. Lee and James C. Moyer for three-year terms, with Lee receiving about 22% of votes withheld. Ernst & Young LLP was ratified as auditor with near-unanimous support. The $1.00 quarterly dividend is payable July 14, 2023, to holders of record on June 30, 2023. The filing contains no changes to financial guidance or reported financial results.

Monolithic Power Systems (MPWR) reported first-quarter 2023 results (quarter ended March 31, 2023) with revenue of $451.1 million, down 1.9% sequentially from $460.0 million in Q4 2022 but up 19.4% year over year from $377.7 million. Growth was driven by Automotive, which rose to $105.3 million from $54.5 million a year earlier, and Storage and Computing, Communications, and Lighting Control. Consumer revenue fell sharply to $63.4 million from $80.0 million. GAAP gross margin was 57.4% versus 57.9% a year ago, and non-GAAP gross margin was 57.7%. GAAP net income was $109.8 million, or $2.26 per diluted share, compared with $1.65 a year earlier, and non-GAAP diluted EPS was $3.00 versus $2.45. Management struck a cautious tone. CEO Michael Hsing said the company remains cautious about near-term business conditions while continuing to invest in business development and infrastructure. The balance sheet strengthened over the quarter, with cash and equivalents rising to $489.0 million from $288.6 million and total stockholders' equity reaching $1.78 billion. Inventory declined modestly to $430.8 million, and total liabilities were $450.4 million. For the second quarter ending June 30, 2023, MPS guided to revenue of $430.0 million to $450.0 million, a GAAP gross margin of 55.9% to 56.5%, and GAAP R&D plus SG&A expenses of $132.5 million to $136.5 million. The guidance implies a sequential revenue decline at the midpoint, reflecting softness in the broader semiconductor and macroeconomic environment. Investors will likely focus on whether the Automotive and Storage and Computing strength can offset Consumer weakness and whether gross margins hold in the mid-50s range.

Monolithic Power Systems (MPWR) reported a strong close to 2022. Q4 revenue was $460.0 million, down 7.1% sequentially from $495.4 million but up 36.7% year over year. Full-year 2022 revenue reached $1,794.1 million, a 48.5% increase over 2021. GAAP gross margin was 58.2% for the quarter and 58.4% for the year, both up from 2021. GAAP operating income rose to $136.9 million in Q4 (vs. $78.6 million a year earlier) and $526.8 million for the full year (vs. $262.4 million). Diluted GAAP EPS was $2.45 for Q4 and $9.05 for the full year. Non-GAAP diluted EPS was $3.17 for Q4 and $12.41 for the year. Growth was led by Storage and Computing and Enterprise Data, while Consumer declined year over year in Q4. Management guided Q1 2023 revenue to $440 million to $460 million, implying a sequential decline at the midpoint. GAAP gross margin is expected at 57.4% to 58.0%, and total stock-based compensation at $40.2 million to $42.2 million. CEO Michael Hsing said the company remains cautious about near-term conditions while investing in infrastructure and business development for long-term growth. The Q1 outlook drops the separate litigation expense forecast, so investors should watch how litigation costs are reported going forward. The board also raised the quarterly cash dividend by 33%, from $0.75 to $1.00 per share, payable April 14, 2023 to holders of record on March 31, 2023. The company added Eileen Wynne, a former Analog Devices Chief Accounting Officer, as a Class II director with no committee assignments. Her initial equity award and $75,000 annual retainer are standard for non-employee directors and do not indicate a material change in governance.

Monolithic Power Systems 8-K Report, Corporate Update (Dec 15, 2022)

Monolithic Power Systems (MPWR) filed a Form 8-K on December 15, 2022 under Item 8.01 (Other Events) to announce its fourth quarter cash dividend of $0.75 per share, payable to stockholders of record as of the close of business on December 30, 2022, with payment scheduled for January 13, 2023. The filing is routine in nature: it discloses no earnings results, guidance, financial statement changes, or material transactions. The announcement is furnished via a press release attached as Exhibit 99.1, with the Inline XBRL cover page (Exhibit 104) included. For investors, the key takeaway is the dividend itself. A $0.75 quarterly payment reflects the company's ongoing commitment to returning capital to shareholders and its confidence in near-term cash generation. Investors seeking to receive this payment must hold shares by the record date, and because of standard market settlement conventions, the ex-dividend date is typically set one business day before the record date, so purchases would need to settle before that date to qualify. The filing contains no forward-looking financial metrics beyond the standard safe harbor language. Investors should review the company's most recent Form 10-K and 10-Q filings for operating performance, margins, and balance sheet strength, which are the more meaningful indicators of the sustainability of the dividend.

Monolithic Power Systems 8-K Report, Financial Results (Oct 27, 2022)

Monolithic Power Systems (MPWR) reported third-quarter 2022 results that beat the prior-year period by a wide margin. Revenue reached $495.4 million, up 53.1% year over year and 7.5% sequentially from $461.0 million in Q2. GAAP gross margin expanded to 58.7% from 57.6%, and GAAP operating income more than doubled to $151.9 million from $77.1 million. GAAP diluted EPS was $2.57 versus $1.44, and non-GAAP diluted EPS was $3.53 versus $2.06. Growth was broad-based across end markets, led by Storage and Computing and Enterprise Data, which grew roughly 64% and 153% year over year, respectively. The outlook is more cautious. Management guided Q4 2022 revenue to $450.0 million to $470.0 million, which implies a sequential decline at the midpoint versus Q3's $495.4 million. CEO Michael Hsing framed the period as one in which "business conditions are softening," while arguing that market share continues to expand on design wins and customer engagement. The guidance implies that investors are weighing near-term demand softness against the company's share gains and strong profitability. The balance sheet remained strong, with $736 million in cash and short-term investments and total stockholders' equity of $1.53 billion. Inventories rose to $397 million from $259 million at year-end 2021, which bears watching given the expected Q4 revenue decline. Stock-based compensation was $43.0 million in the quarter, and the company's non-GAAP metrics exclude it.

GAAP diluted EPS was $2.37 versus $1.16, and non-GAAP diluted EPS was $3.25 versus $1.81.

For the six months, revenue reached $838.7 million, up 53.1%, and GAAP net income was $194.2 million.

The guidance implies continued sequential growth, though the company cited risks including export controls on China, supply constraints, Russia-Ukraine effects, and cyclicality in the semiconductor industry. This 8-K is furnished under Item 2.02, so the press release and webinar materials are not deemed filed under the Exchange Act.

Monolithic Power Systems 8-K Report, Shareholder Vote Results (Jun 21, 2022)

Monolithic Power Systems (MPWR) reported the results of its June 16, 2022 Annual Meeting of Stockholders and declared a second-quarter cash dividend of $0.75 per share. The dividend is payable July 15, 2022 to holders of record at the close of business on June 30, 2022. The filing is largely procedural, but the vote tallies offer some signals on shareholder sentiment. Stockholders re-elected three Class III directors (Michael Hsing, Herbert Chang, and Carintia Martinez) to terms ending in 2025. Hsing and Martinez each received roughly 39.6 million votes for, with about 1.9 million withheld. Herbert Chang drew about 22.1 million votes for and about 19.4 million withheld, meaning roughly 47% of votes cast for him were withheld. That is an unusually high level of opposition for a director and is the most notable item in the filing. Stockholders also ratified Ernst & Young LLP as auditor for 2022 with overwhelming support (about 43.1 million for versus about 44,000 against or abstaining). The advisory say-on-pay vote on 2021 named executive officer compensation passed, but with materially less support: about 29.8 million for, 11.4 million against, and 0.4 million abstaining. Excluding abstentions and broker non-votes, roughly 72% of votes cast supported the pay program, and about 28% opposed it. Investors may want to review the proxy statement for the reasons behind this dissent. The $0.75 quarterly dividend, if sustained, would equal $3.00 annualized.

Monolithic Power Systems 8-K Report, Financial Results (May 2, 2022)

Monolithic Power Systems (MPWR) reported first-quarter 2022 results that beat on the top and bottom lines, with revenue of $377.7 million, up 12.2% sequentially from $336.5 million and 48.4% year over year from $254.5 million. GAAP gross margin expanded to 57.9% from 55.4% a year earlier, and GAAP diluted EPS rose to $1.65 from $0.95. Non-GAAP diluted EPS was $2.45 versus $1.46, with the gap driven mainly by stock-based compensation of $39.8 million, up from $28.6 million. Growth was broad-based, led by DC-to-DC products and the newly reorganized Storage and Computing and Enterprise Data end markets, which rose sharply year over year, while Automotive, Industrial, Communications and Consumer also grew. The balance sheet remains strong, with cash and short-term investments of roughly $773.5 million and stockholders' equity of $1.33 billion. Inventory increased to $311.0 million from $259.4 million at year-end, roughly 20% higher, which investors should monitor against the strong sequential revenue growth. Operating expenses rose faster than revenue on a GAAP basis, reflecting higher R&D and SG&A. For Q2 2022, management guided revenue to $420 million to $440 million, implying further sequential growth, with GAAP gross margin of 58.4% to 59.0% and GAAP R&D plus SG&A of $132.7 million to $136.7 million. The company also disclosed a litigation expense outlook of $2.3 million to $2.7 million. Management's risk factors highlight the Russia-Ukraine conflict, COVID-19 restrictions in China and Taiwan, semiconductor cyclicality, and export controls affecting China.

GAAP net income was $72.7 million ($1.51 diluted EPS) for the quarter and $242.0 million ($5.05 diluted EPS) for the year. Non-GAAP diluted EPS, which excludes stock-based compensation and deferred compensation plan effects, was $2.12 for Q4 and $7.45 for the year. Growth was led by computing and storage, which nearly doubled in Q4 to $118.5 million, and by automotive, which rose 43% to $56.4 million. Management attributed the performance largely to a 40% increase in fab and assembly capacity supporting a ramp of high-value, greenfield products. The Board approved a 25% increase in the quarterly cash dividend, from $0.60 to $0.75 per share, payable April 15, 2022 to holders of record on March 31, 2022. At year-end 2021, the company held $725 million in cash, cash equivalents and short-term investments, against total liabilities of $342 million. Management guided Q1 2022 revenue to $354–366 million, with GAAP gross margin of 57.4–58.0% and GAAP R&D plus SG&A of $119.2–123.2 million, including $35.8–37.8 million of stock-based compensation.

The press release and webinar materials are furnished under Item 2.02 and are not deemed filed for purposes of Section 18 of the Exchange Act. Investors should weigh the strong growth against the forward-looking risks flagged in the safe harbor statement, including semiconductor cyclicality, supply constraints from third-party manufacturers, export controls affecting China, and COVID-19.

Monolithic Power Systems 8-K Report, Shareholder Vote Results (Jun 11, 2021)

Monolithic Power Systems (MPWR) filed this 8-K to report the results of its June 10, 2021 Annual Meeting of Stockholders and to announce its second-quarter 2021 cash dividend. The filing contains no financial results, guidance, or operating metrics. Its substance is governance and capital return. Stockholders re-elected Eugen Elmiger and Jeff Zhou as Class II directors for three-year terms ending at the 2024 annual meeting. Ernst & Young LLP was ratified as the independent registered public accounting firm for fiscal 2021, with about 42.3 million votes for and fewer than 17,000 against. Stockholders also approved the 2020 compensation of the named executive officers on an advisory basis. That say-on-pay proposal passed with roughly 88% of votes cast in favor, though about 4.7 million votes were against, which is a meaningful minority dissent. The company declared a $0.60 per share dividend payable July 15, 2021 to holders of record at the close of business on June 30, 2021. For income-oriented investors, the filing confirms the dividend is continuing. It does not state whether the dividend is a permanent quarterly policy or a one-time distribution.

Monolithic Power Systems 8-K Report, Executive Changes (May 28, 2021)

Monolithic Power Systems (MPWR) filed an 8-K on May 28, 2021 reporting a board change rather than a financial event. On May 27, 2021, the Board appointed Carintia Martinez as a director, effective immediately, filling a Class III seat whose term expires at the 2022 annual meeting. She was not assigned to any committees at appointment. The filing contains no financial results, guidance, or operational updates. Ms. Martinez, 55, has been Vice President and Chief Information Officer of Thales Alenia Space since January 2018, and previously held senior information systems and quality roles at Renault Group and Nissan. Her background is primarily in large-scale IT and enterprise operations, which may add technology and operational oversight to the Board. Compensation is standard for a new non-employee director: an initial grant of 583 RSUs vesting 50% at one year and 50% at two years, plus a prorated 2021 annual retainer of $70,000. Full single-trigger acceleration applies on a change of control only if the successor fails to assume the awards. For investors, this is a routine governance update. The appointment is modest in scale and does not signal a change in strategy or financial condition. The company also reported no related-party transactions involving Ms. Martinez and no arrangements under which she was selected.

Monolithic Power Systems 8-K Report, Financial Results (May 4, 2021)

Monolithic Power Systems (MPWR) reported first-quarter 2021 results that beat its prior-quarter levels by a wide margin. Revenue reached $254.5 million, up 9.2% sequentially from $233.0 million and up 53.5% year over year from $165.8 million. GAAP gross margin was 55.4% (non-GAAP 55.8%), roughly flat year over year, while GAAP operating expenses rose sharply to $95.0 million from $60.5 million, largely due to a $28.6 million stock-based compensation charge. GAAP operating income rose 49% to $46.1 million, and GAAP diluted EPS was $0.95 versus $0.77 a year earlier. Non-GAAP diluted EPS was $1.46 versus $0.95. Growth was broad-based across end markets. Automotive revenue nearly doubled to $44.9 million from $23.3 million, consumer rose to $66.2 million from $37.4 million, industrial grew to $39.8 million from $25.2 million, and computing and storage reached $67.5 million from $52.0 million. DC-to-DC products, which made up $241.4 million of revenue, drove most of the increase. The balance sheet remains strong, with cash and short-term investments totaling about $639 million and stockholders' equity of $1.02 billion, against modest total liabilities of $287 million. For the second quarter of 2021, management guided revenue to $274 million to $286 million, GAAP gross margin to 55.1% to 55.7%, and fully diluted shares to 47.3 million to 48.3 million. The company also cited a strong CEO quote about reaching a path to multi-billion-dollar revenue. Investors will likely focus on whether the guided sequential growth of roughly 8% to 12% can be sustained given supply constraints and the cyclical semiconductor backdrop, as well as on the step-up in stock-based compensation.

Monolithic Power Systems 8-K Report, Financial Results (Feb 4, 2021)

Monolithic Power Systems (MPWR) reported strong fourth-quarter and full-year 2020 results, capping a year of rapid growth. Q4 2020 revenue was $233.0 million, up 39.8% year over year but down 10.2% sequentially from $259.4 million in Q3. GAAP gross margin was 55.3%, GAAP operating income rose to $40.0 million from $30.7 million, and GAAP diluted EPS was $0.90 versus $0.70 a year earlier. For full-year 2020, revenue grew 34.5% to $844.5 million, GAAP net income reached $164.4 million ($3.50 per diluted share), and GAAP operating expenses rose to $307.1 million from $243.8 million, driven largely by stock-based compensation and litigation expense of $7.8 million. Growth was broad-based across end markets. Consumer (+$26.7 million YoY in Q4), Automotive (+63% YoY), Communications (+36% YoY), Industrial and Computing and storage all grew. Communications showed the largest full-year gain, up 68% to $142.3 million.

Investors should note that the guidance midpoint implies modest sequential growth despite the strong Q4 exit, and that GAAP results carry meaningful stock-based compensation (about $23 million per quarter). Non-GAAP metrics are presented alongside GAAP figures, and the filing notes the cautionary forward-looking statements, including COVID-19 and semiconductor cyclicality risks.
