MACOM Technology Solutions Holdings, Inc. (MTSI) Up 8.8% — Should I Secure an Entry Before Liftoff?
MACOM Technology Solutions Holdings, Inc. (MTSI) is pushing sharply higher this Wednesday, last trading at $246.30 on the NASDAQ — a $19.82 gain from the prior close of $226.48. The rebound recovers meaningful ground, but MTSI still sits roughly 41.2% below its 52-week high of $418.90, a level reached on May 27, 2026. That gap is the opportunity. A company whose fundamentals have strengthened through the year is trading at a deep discount to where the market valued it six months ago.
Volume stands at roughly 664,579 shares with the session still open, about 43% of the 90-day average of 1,563,380. The advance is coming on measured turnover so far.
Why MACOM Technology Solutions Holdings, Inc. Price is Moving Higher
The move is part of a powerful semiconductor and AI-infrastructure rebound, and MTSI is being carried higher with the group. The Philadelphia Semiconductor Index gained 7.21% during the session. Micron (MU) is up 6.8%, and the gains extend across MACOM's closest peers. Marvell Technology, Inc. (MRVL) jumped 12.81% and Monolithic Power Systems, Inc. (MPWR) climbed 11.20%. MTSI's 8.75% advance tracks that sector-wide move almost exactly, which shows investors bidding up the AI hardware supply chain as a whole.
The spark came from CoreWeave's (CRWV) results on November 10. The AI cloud provider reported Q3 revenue of $3.661 billion, up 168% year over year. It raised its 2026 revenue outlook to $13.0 billion to $13.3 billion and disclosed a backlog of $132.5 billion. Those numbers directly countered worries that AI-computing demand was losing steam. TSMC added to the signal the same day, reporting October sales up 59.7% year over year. For MACOM, whose high-speed connectivity products sit inside the data center build-out, confirmation that hyperscale and neocloud spending remains robust is exactly the demand signal that matters.
MACOM entered this rally with its own results already giving the stock a solid base. On November 5, the company reported fiscal Q4 2026 adjusted EPS of $2.09, beating the $2.00 consensus. Revenue of $424.8 million topped the $420.2 million estimate and grew 62.7% year over year. Net income rose to $139.4 million from $45.1 million a year earlier, a more than threefold increase. Management then guided fiscal Q1 2027 revenue to $450 million to $460 million and adjusted EPS to $2.21 to $2.29, pointing to continued sequential growth. Today's sector rebound is the immediate driver, but those results give investors a concrete reason to believe MACOM can convert AI demand into earnings.
What is the MACOM Technology Solutions Holdings, Inc. Rating - Should I Buy?
Weiss Ratings assigns MTSI a C rating. Current recommendation is Hold. The rating reflects a company with first-class business fundamentals whose stock has been a difficult ride over the past year. That combination makes MTSI a name with real upside for investors willing to manage the swings.
The fundamental case is strong. The Excellent rating on the Growth Index reflects revenue growth of 35.77%, a pace that accelerated to 62.7% year over year in the fiscal fourth quarter. For an analog and mixed-signal semiconductor company, that is exceptional expansion, driven by data center connectivity demand. The Good rating on the Efficiency Index is supported by a 20.69% profit margin and a 17.18% ROE. Both figures show MACOM turning that growth into genuine profitability rather than chasing volume at the expense of returns. The Excellent rating on the Solvency Index adds another layer of confidence. MACOM has the balance sheet to keep investing in next-generation optical and RF products without financial strain as the AI cycle unfolds.
Where the picture becomes more nuanced is in how the stock itself has behaved. The Fair rating on the Total Return Index reflects a share price still about 41% below its May high of $418.90, despite the earnings momentum. The Weak Volatility Index shows up clearly in today's session. An 8.75% one-day jump driven by a sector-wide reaction to CoreWeave's numbers shows how sharply MTSI responds to shifts in AI sentiment, in both directions. With a forward P/E of 72.62, the market is already pricing in substantial growth, which amplifies those swings. These two dimensions are what hold the overall rating at C rather than lifting it into Buy territory.
Within the Information Technology sector, MACOM sits alongside Advanced Micro Devices, Inc. (AMD, C), Marvell Technology, Inc. (MRVL, C), and Astera Labs, Inc. (ALAB, C), all of which share the same AI-infrastructure exposure and the volatility that comes with it. Monolithic Power Systems, Inc. (MPWR, C+) holds a modestly stronger risk/reward profile in the Weiss framework.
About MACOM Technology Solutions Holdings, Inc.
MACOM Technology Solutions Holdings, Inc. (MTSI) is an Information Technology company that designs and manufactures analog, mixed-signal, RF, microwave, millimeter-wave, and optical semiconductor products. Headquartered in Lowell, Massachusetts, the company serves three primary end markets: data center, telecommunications, and industrial and defense. Its products move and convert signals at the physical layer of high-performance networks, in settings where speed, power efficiency, and signal integrity are critical.
In the data center, MACOM supplies transimpedance amplifiers, laser and modulator drivers, linear equalizers, and clock and data recovery devices. These components enable the high-speed optical links connecting servers, switches, and AI accelerators. As cloud operators push toward 800G and 1.6T connectivity, these components become increasingly important to the bandwidth AI clusters require. In telecommunications, the company provides products for optical access networks, metro and long-haul infrastructure, and wireless base stations. Its industrial and defense business includes power amplifiers, gallium nitride technology, and microwave and millimeter-wave components for radar, communications, and test and measurement applications.
MACOM's competitive strength comes from decades of RF and microwave engineering expertise, a broad portfolio spanning both electrical and optical domains, and its own compound semiconductor fabrication capabilities. That breadth lets the company offer customers complete chipset solutions rather than standalone parts. The industrial and defense franchise adds diversification and steady, long-cycle demand that balances the faster-moving data center market.
Investor Outlook
MACOM Technology Solutions Holdings, Inc. (MTSI) carries a Weiss Rating of C (Hold). Today's rally shows how much upside the stock still holds while it trades roughly 41% below its May peak. Investors should watch whether MACOM delivers on its fiscal Q1 2027 guidance of $450 million to $460 million in revenue, and whether the AI spending signals from CoreWeave and TSMC keep flowing through to data center connectivity orders.
