How it works

What's covered

A curated list of 35 AI-infrastructure stocks in six lanes: semis and compute, networking and optical, power and cooling, data centers, bitcoin miners and neoclouds, and the hyperscalers whose spending drives demand. The calendar shows this week through the next 30 days (or 45, with the range switch); each ticker page adds report history and 90 days of SEC filings.

Announced earnings dates

Confirmed dates are taken from each company's own press release or investor-relations page, and every event links to that source. We don't copy dates from third-party earnings calendars. When a company calls a date tentative, the event says so.

Once results are out, the date gets a check mark (“Reported”) and links to the results filing, which isn't listed a second time as a separate SEC filing.

Estimated earnings dates

Companies usually announce their earnings date only two to four weeks ahead. Until they do, we show an estimate: the same quarter's report date from last year, moved forward 52 weeks so it lands on the same weekday, with a window of ±3 days. Estimates have a dashed outline and a “~” or “est” marker. They can be off by a week or more, and each one disappears as soon as the company announces its date. The likely time of day follows the company's latest report; when that differs from its usual timing, the details say so.

Before the open or after the close

Report timing comes from when each company filed its results with the SEC, usually an 8-K with Item 2.02, “Results of Operations”. Filed before 9:30 a.m. ET counts as before the open; at or after 4:00 p.m. ET counts as after the close. A few companies publish results without that 8-K; for them we use the quarterly report filing instead. When a company releases after the close but files the next morning, its history shows the next day, before the open.

Foreign issuers such as TSMC, Arm and Nebius file a different form (6-K) that doesn't mark results releases, so their history is entered by hand from the releases themselves, each linked to its 6-K. The timing is the one the company published (for example, a webcast at 8:00 a.m. ET means before the open), because a 6-K is often filed hours after the release.

Investor days and conferences

Investor and analyst days, and industry conferences such as the OCP Global Summit, are added by hand. Each one is checked against the company's or organizer's own page, or a participating company's official event page, and links to it.

SEC filings

8-Ks, quarterly and annual reports (10-Q, 10-K, 20-F, 6-K), registration statements (S-1, S-3) and prospectus supplements (424B5) come straight from SEC EDGAR, with the exact time they were accepted, and link to the filing.

Update schedule

Everything refreshes every morning before the US market opens (about 6:30 a.m. ET). The time of the latest refresh is shown on every page; if a refresh is ever missed, the page says so.
