Why MACOM Technology Solutions Holdings, Inc. (MTSI) Stock Rose 14.5% on Aug 6, 2026
The clearest new catalyst: A fiscal Q4 guide roughly 35% above consensus.
Why did MTSI stock rise?
MACOM Technology Solutions rose 14.49% on August 6, from $263.46 to $301.64, after reporting fiscal Q3 2026 results before the open that morning, with the call at 8:30 a.m. ET. The quarter was a record — revenue of $342.2 million, up 35.8% year over year and 18.4% sequentially, adjusted EPS of $1.40 against $1.35 consensus — but the guidance did the work: MACOM guided fiscal Q4 revenue to $415-425 million against roughly $365 million consensus and adjusted EPS to $1.97-2.03, a midpoint about 35% above the roughly $1.48 FactSet consensus.
- A fiscal Q4 guide roughly 35% above consensus: Guidance of $1.97-2.03 adjusted EPS carries a $2.00 midpoint against a FactSet consensus near $1.48, with revenue guided to $415-425 million versus roughly $365 million expected. This is the cleanest identifiable driver of the move — stronger than simply calling it an earnings beat.
- Record Q3 on data-center demand: Revenue of $342.2 million rose 35.8% from $252.1 million a year earlier and 18.4% from $289.0 million in the prior quarter. Adjusted EPS of $1.40 beat the $1.35 consensus on revenue expectations near $335.5 million — a genuine adjusted, non-GAAP beat. GAAP net income was $100.7 million, or $1.28 per diluted share.
- Record book-to-bill and data-center revenue: Book-to-bill reached a record 1.6:1 and data-center revenue rose roughly 40% sequentially to a record $137.6 million from about $98.2 million.
- A rally that had to fight the tape first: MACOM opened at $270.00, up only 2.5%, and actually traded below the prior close at $261.95 before running to close at $301.64. The broader semiconductor index fell as much as 2.5% early that morning before reversing, so the initial fade fits the session dynamics rather than contradicting the guidance.

What it could mean for MTSI investors
The constructive case
- Fiscal Q4 guidance of $415-425 million revenue and $1.97-2.03 adjusted EPS sits far above consensus on both lines.
- A record 1.6:1 book-to-bill points to booking momentum well ahead of shipments.
- Data-center revenue rose roughly 40% sequentially to a record $137.6 million, broadening the growth base alongside industrial, defense and telecom.
The cautious case & what could invalidate it
- A guide about 35% above consensus resets the bar sharply; the next quarter has to clear the new expectation, not the old one.
- The stock entered the print already up about 54% year to date and closed the session up roughly 76% for 2026, so a great deal of good news is now in the price.
- Book-to-bill above 1 reflects orders, not revenue — watch whether the backlog converts on the guided schedule.
- Data-center concentration cuts both ways: the segment driving the beat is also the one most exposed to any AI-infrastructure digestion.
