Can MPS keep converting AI data center design wins into revenue at strong margins, or will module costs and uneven demand keep profitability at the low end?

Last 4 earnings calls · through Q2 FY2026

Bull case

  • Data center socket wins

    The bull case is that MPS has won power sockets across many AI and server customers, so data center growth depends on design wins rather than one buyer's budget.

  • Chips to modules and systems

    Moving from chips to modules and full power systems raises the value of each socket and lets the company sell more into designs it has already won.

  • Growth outside data centers

    Automotive, communications and industrial design wins give MPS growth outside data centers, which management argues smooths the cycle and protects revenue.

  • Cash returns and margins

    Operating margin is expanding and the company returns much of its free cash flow through dividends and buybacks while keeping its share count roughly flat.

Bear case

  • Gross margin at low end

    The bear case is that gross margin stays near the bottom of the target range because modules and systems cost more to build and order visibility limits mix management.

  • Data center demand dependence

    A growing share of revenue depends on data center spending that management says it cannot forecast and that has swung sharply in past cycles.

  • Consumer and PC weakness

    Consumer and notebook demand remain weak, and memory shortages could shrink the personal computer market that MPS supplies power chips into.

  • Capacity spending ahead of demand

    Capacity, test and module assembly must keep expanding ahead of demand, which raises capital spending and has already pulled free cash flow below the prior year.

Bull and bear points

Growth & Execution

In short: Data center wins drive rapid growth, while consumer and notebook demand stay soft and hard to predict.

Bull · 2

  • Data center growth floor raised to 130% for 2026

    Management now expects enterprise data revenue to grow about 130% in 2026, up from a 30% to 40% range given two quarters earlier, after backlog extended.

  • All end markets grew sequentially in the June quarter

    Revenue grew 47.6% from a year earlier to a record, with every end market up sequentially, so growth is broader than the AI server build-out alone.

Bear · 2

  • Consumer and notebook demand remain the weak spots

    Management stays cautious on consumer and notebook, where memory shortages could shrink the market and MPS sells only into the higher-margin parts of it.

  • Order visibility still stretches only a few quarters

    Even with book-to-bill above one, management says it cannot see past the next few quarters, so guidance rests on customer ramps it does not control.

Profitability & Financial Strength

In short: Operating margin is expanding and cash returns are steady, but gross margin sits at the low end of its range.

Bull · 2

  • Operating margin expanded 6.2 points from a year ago

    Operating margin reached 31.0% in the June 2026 quarter as spending grew more slowly than revenue, and management expects that leverage to continue as sales rise.

  • Dividend raised 28% and buyback pool increased to $1 billion

    MPS returned 72% of free cash flow over three years through dividends and buybacks and kept its diluted share count flat, so per-share profit is not diluted.

Bear · 1

  • Free cash flow fell as capital spending rose

    Free cash flow was $586 million over the last 12 months, down from $706 million a year earlier, as spending on capacity and automated test equipment increased.

Market Position

In short: Power-density leadership wins sockets, while large rivals and a cyclical chip market pressure pricing.

Bull · 2

  • Single-chip integration gives the highest power density

    MPS builds a full power stage on one piece of silicon, which management says packs more current into small spaces and wins optical module and server sockets.

    Q1 FY2026 call

  • Management reversed its stance on gallium nitride

    The CEO once said gallium nitride was only being evaluated; MPS now develops its own devices while keeping silicon carbide for 800-volt data center power.

Bear · 2

  • A past downturn halved the operating margin

    In the fiscal 2011 downturn revenue fell 10.2% and operating margin dropped from 13.9% to 6.8%, showing how quickly a chip cycle compresses profit.

    Filed financials

  • Management will not raise prices in tight supply

    MPS says it does not gouge customers when supply is tight and passes through only specific input-cost increases, which limits how much scarcity lifts margin.
