The simple version

Guidance is what a company says it expects to earn in the quarter or year directly ahead. A revenue target is what it hopes to be earning several years out. They sound like the same kind of statement, and they are not.

Guidance arrives in a document the company files, carries a stated margin of error, and gets measured against the actual result on a date set in advance. A long-horizon target can arrive in a slide on a webcast, with no margin, no filing, and no day on which anyone has to report how it went.

Both are predictions. Only one of them is scheduled to be graded.

The numbers

• Marvell's guidance for the quarter ending in October 2026: net revenue expected to be $3.150 billion plus or minus 5% (Form 8-K Exhibit 99.1, filed August 27, 2026)
• Non-GAAP diluted earnings per share expected to be $1.10 plus or minus $0.05; GAAP expected to be $0.53 plus or minus $0.05 (same exhibit)
• The prior quarter's result: net revenue of $2.739 billion, which the release states was $39.0 million above the mid-point of the guidance given on May 27, 2026 (same exhibit)
• That exhibit carries a section headed Forward-Looking Statements under the Private Securities Litigation Reform Act of 1995, the statutory safe harbor (same exhibit)
• Marvell held an investor day on October 6, 2026 (Marvell press release, August 3, 2026)
• Marvell issued no press release for that investor day and filed no 8-K in October 2026 (Marvell newsroom and EDGAR, both checked October 7, 2026)

The three things a target does not have

The first is the document. Guidance shows up inside a release the company files, which pulls in the statutory protection of the Private Securities Litigation Reform Act of 1995. That same paragraph lists the words signalling a prediction, and "targets" is one of them, which is the company stating in its own filing which of its own words are forecasts.

The second is the margin. "Plus or minus 5%" is the company declaring how much room it needs around its own estimate. A target with a high end and a low end years out is not that: it is the spread of outcomes the company would be willing to call success.

The third is the checking date. A quarter ends, the real figure prints, and the company has to publish the distance between what it said and what happened. No rule forces that reckoning for a five-year figure.

The actual math on a 5% margin

Take the prior quarter, where both halves exist. Guidance was given on May 27, 2026, and the result came in $39.0 million above the mid-point, which works out to about 1.4% above it on a mid-point of roughly $2.700 billion.

A 5% margin on $2.700 billion is about $135 million in either direction. So the band the company gave itself was roughly three and a half times wider than the gap that actually showed up.

That is not a criticism, it is the point. The margin is a statement of honest doubt one quarter out, and it was generous even then. Now ask what an honest margin would look like on a figure five years out, and notice that nobody is required to publish one.

What this means

When a company announces a long-horizon revenue target, the useful question is not whether the figure is big. It is where the figure was published.

A figure in a filed document comes with statutory safe harbor language, usually a margin, and a date on which it gets checked. A figure in a webcast slide may come with none of those, and there may be no filing to read at all.

That is worth knowing before a headline figure does any work in your thinking.

What this is NOT

This article explains the difference between filed guidance and a long-horizon revenue target, using Marvell's August 27, 2026 quarterly release as the example. It is not a recommendation to buy, sell, or hold Marvell or any security, and it takes no view on the company's prospects, its valuation, or whether any target is achievable. It is not a suggestion that long-horizon targets are dishonest; companies are allowed to describe where they are trying to go, and plenty of them get there. It does not describe what Marvell said at its October 6, 2026 investor day, because the company published no release and filed no document for that event, and the comparison here runs between filed guidance and the general category of unfiled long-horizon targets. It does not predict Marvell's results for any quarter. The percentage conversion, the mid-point back-solve, and the comparison between the stated margin and the realized gap are our arithmetic on figures the filing states. Marvell's release states that its forward-looking statements are not guarantees of results. ClearMoneySchool uses AI tools from Anthropic, and Google is an investor in Anthropic; Google has been reported in the press as a Marvell customer, and this article makes no claim about that relationship. This is not a political endorsement or criticism of anyone.
