Why Is Analog Devices Stock Moving Today?

Analog Devices edged lower 0.89% to $373.26 after reporting record fiscal third-quarter results and guiding fiscal fourth-quarter earnings above consensus. The session close is the least interesting number here: the stock finished close to where it started. What happened in between is the story.

Measured at the print, ADI moved from $383.0 to $387.01 over the following 15 minutes — +1.047%. The first row a minute earlier measured +0.818%. It then gave all of that back and more, ending -3.55% below the level the results had lifted it to.

The quarter was a record on every line

Revenue of $4.02bn was up 40% year over year, against a $3.91bn consensus. Adjusted diluted EPS of $3.45 beat the $3.34 expected. Gross margin held at 67.3% and operating margin at 40.1%, and free cash flow was $1.458bn for the quarter. The company returned $1.7bn through dividends and share repurchases and declared a quarterly dividend of $1.1 per share payable on 15 September.

Chief executive Vincent Roche said the company exceeded the midpoint of its revenue, margin and earnings outlook on broad-based demand. On the numbers, that is exactly what happened.

And the guidance was above consensus, not merely in line

Fiscal Q4 guidance is revenue of $4.3bn plus or minus $0.1bn, with adjusted EPS of $3.86 plus or minus $0.15 — a range of $3.71 to $4.01. Consensus sat at $3.54.

That detail is worth stating precisely, because it is stronger than the usual "raised guidance" phrasing: the bottom of the guided range is above the consensus number. For the outlook to disappoint, ADI would have to miss its own worst case.

The reversal, measured

This is the shape that separates a bad quarter from a repriced expectation. A genuinely disappointing result shows up immediately — the tape reads the numbers and marks the stock down inside the first minutes. That is not what happened here. The first fifteen minutes were positive, twice.

The selling came later, from $387.01 down to $373.26, -3.55% off the level the market first put on these results. Moves with that shape usually reflect the conference call and the second read rather than the release: what the guidance assumes, what the margin trajectory implies, how much of the 40% growth is durable rather than a build-out that pulls demand forward.

The sector was not helping

Semiconductors had a poor session even though the wider market did not: the Nasdaq Composite managed +0.16% while Broadcom fell sharply on a separate story about Google adding a second custom-silicon supplier, and Texas Instruments and NXP were lower too. So part of ADI's day is simply the group it trades in.

But the group does not explain the shape. ADI rose on its own news and only reversed later, which is a different event from a stock that opens weak alongside its sector. Measured against where its own results had put it, the give-back was -3.55%. That is the part which belongs to this company rather than to semiconductors.

What the next print tests

ADI has now put a precise number on the table: adjusted EPS of $3.71 to $4.01 for fiscal Q4, on revenue of $4.3bn give or take $0.1bn. Landing inside that range would confirm the guidance was as conservative as its low end suggests. Landing below it would validate whatever the market decided during today's reversal.

Either way, the useful record from today is not the -0.89% close. It is that the results themselves measured +1.047%, and everything negative happened after the tape had already read them.
