How to Read a 10-Q

The SEC's investor guidance is explicit: a Form 10-Q is filed after the first three fiscal quarters, includes unaudited financial statements, and gives you a continuing view of the company's financial position during the year.

That phrasing matters. A 10-K is the annual map. A 10-Q is the update to the map. If customer concentration spikes in April, a tax obligation becomes real in August, or regulators open a new case in January, you will usually see it in the next 10-Q long before the next annual report.

This is why investors who care about what is true now need the latest filing, not the most recent annual summary sitting in a screener. The useful question is not, “What does this company look like in general?” It is, “What changed since the last clean baseline?”

NVIDIA's first-quarter fiscal 2025 10-Q already showed unusual concentration: one direct customer was 13% of revenue, a second was 11%, and two indirect customers each represented 10% or more of revenue.

One quarter later, in NVIDIA's second-quarter fiscal 2025 10-Q, that concentration got tighter. Four direct customers crossed the 10% threshold: 14%, 11%, 11%, and 10%. NVIDIA also said two indirect customers were each above 10%.

A screener will happily show you exploding quarterly revenue. The 10-Q shows the more important question underneath: how much of that revenue is leaning on a small set of counterparties right now?

Apple's third-quarter 2024 10-Q said a European Court of Justice decision on the State Aid case was still expected later in 2024. That same filing also said management did not believe there was a reasonable possibility of a material loss above recorded accruals for asserted legal claims.

By Apple's first-quarter 2025 10-Q, the picture was different. Apple said contractual cash requirements had changed materially because of commercial paper, manufacturing purchase obligations, and the State Aid Decision tax payable. The filing also expanded its legal proceedings and risk factor updates around the EU Digital Markets Act, the U.S. Department of Justice antitrust lawsuit, and the risk to Google search distribution payments if proposed remedies were imposed.

None of that requires a new annual report. That is the point of the 10-Q. It is where a company updates the market when the risk, liability, or operating constraint becomes current enough that it can no longer wait for the next 10-K.

At DeepFundamental, the 10-Q is not filler between annual reports. It is often the first place a material change becomes visible in a structured, traceable form.

That is why we parse the filing itself instead of relying on stale annual data or condensed vendor summaries. If a company just added a new dependency, new lawsuit, new cash obligation, or new concentration risk, the latest 10-Q is usually where that fact first becomes usable.
