Why Monolithic Power Systems Stock Is Up 54% Over the Past Year
Monolithic Power Systems (MPWR) stock has gained 54% over the past year, closing at $1,268 on August 31, 2026, up from $824 a year earlier. That run was not a straight line. Shares roughly doubled between February and June before pulling back from a June 30 quarterly close of $1,382 to where they sit now, a reminder that even a strong AI power-chip story gets repriced along the way.
The clearest driver sits in the Q2 2026 results MPS posted on July 30. Revenue hit a record $980.6 million, up 22% sequentially and 48% year over year, beating the $902.5 million analyst estimate. Adjusted EPS came in at $6.50 against a $5.87 estimate. Enterprise Data revenue, the segment covering AI servers and data center power, jumped 45% sequentially. Shares rose 9.7% the next trading day as the company also guided Q3 revenue to $1.14 billion-$1.16 billion, well above the Street’s $981.9 million consensus.
CFO Tony Balow tied that growth directly to the AI buildout on the earnings call, telling analysts in Q2 earnings call that CPU power “has been one of the growth drivers for us in Enterprise Data” and that “to the extent that agentic AI drives further CPU growth, that will continue to be a tailwind for us.” Management also disclosed book-to-bill running above 1 and low channel inventory, evidence the demand is orders-driven rather than a restock.
The board backed that confidence with capital: it added $500 million to the buyback program in July, lifting total authorization to $1 billion. Between record bookings, a guidance beat that outran estimates by 16%, and a growing repurchase pool, Monolithic Power Systems stock’s 54% year looks less like momentum and more like the market catching up to what AI infrastructure spending is doing to its order book.
Monolithic Power Systems Stock’s Target Keeps Climbing Faster Than the Price
Analysts currently carry 12 buys, 3 outperforms, 1 hold, and 1 underperform on Monolithic Power Systems stock, and their mean target sits at $1,843 against the $1,268 close, a 45% gap.
The trend matters as much as the current snapshot. The mean target has climbed from $763 in June 2025 to $1,843 now, a 142% increase, while the stock itself rose 73% over the identical window. Analysts raised the target sharply after the December 2025 and June 2026 quarters, each time the Target/Close ratio pushing back above 120%.
That ratio now reads 145%, the highest of the six quarters shown, meaning the Street has widened the gap even as the stock cooled off its June peak. Coverage held steady in the 13-to-14 range throughout, so this is a repricing story, not a story of analysts abandoning or piling into the name.
The multiple backs up the estimate story. MPWR stock traded at 42x forward earnings a year ago and peaked near 54x on June 30, 2026, right alongside the stock’s high for the period. By August 31, that multiple had compressed to 40x, cheaper than where it started the year even after the 54% gain, which means forward earnings estimates grew faster than the stock did and the pullback off the June peak was a multiple correction, not a demand scare.
TIKR Values Monolithic Power Systems Stock at $2,549, More Than Doubling the Street Target’s Runway
TIKR’s mid-case model values Monolithic Power Systems at $2,549 by December 2030, implying 101% total return from the current price of $1,268, or 17.5% annualized over 4.3 years.
That puts the model’s target 38% above where the Street’s mean target already sits, a wide spread for a chipmaker most of the sell side already rates a buy. The model’s confidence traces back to the same Enterprise Data engine driving the past year’s move: revenue growing 47.6% year over year, a Q3 guide that beat consensus by double digits, and management describing order visibility that now extends beyond a single quarter.
Where the Street is underwriting the AI power cycle already in the numbers, TIKR’s model is underwriting several more years of the same trajectory continuing to compound.
