Computed from SEC EDGAR filings and closing prices — not copied from any wealth ranking. Dataset . How we calculate this.
Revenue and net income below are for fiscal period FY2025, the period label carried by this company’s own annual XBRL filings to the SEC. Fiscal years do not line up between companies — one company’s FY2026 can cover much the same months as another’s FY2025 — so compare the periods, not just the numbers.
US GAAP has no one “total revenue” tag that every filer uses. A bank reports interest and dividend income separately from non-interest income; closed-end funds, blank-cheque companies and some property trusts report the same way; and a company that has not sold anything yet — a drug developer still in trials, for instance — files no revenue at all. Adding two differently defined income lines together would produce a number that appears in no filing, so we publish a revenue figure only where the filing tags one annual, US-dollar revenue fact we can point at. A blank here means no such tag, not that we failed to look.
Headcount comes from Yahoo Finance, not from a filing. The date beside it is the day we retrieved the figure — it is not the date the company counted its staff, and Yahoo does not publish that date. Unlike the SEC filings behind the other figures on this page, this one carries no open licence, so we publish the number and nothing else from that source.
Everyone below has filed at least one insider report against this company.
Value is that share count priced at the same closing price used everywhere else on this site. A row priced from only some of a person’s securities says so — we do not quietly present a partial sum as a complete one.
| Insider | Reported role | Shares | Value | Last action |
|---|---|---|---|---|
| Joseph Edelman | Board Member | 5,875,851 | $8.70M | S Open-market sale Apr 3, 2025 position reported |
| Richard Douglas | Board Member | 195,000 | $288.6K | P Open-market purchase Mar 19, 2026 position reported |
The rest — awards, shares withheld to pay tax, option exercises, gifts and so on — follow from an employment contract or a transfer arranged off-market, not from a decision to buy or sell, so counting them would turn this into a pay table.
A price of 0.00 is a real reported figure on gifts (G) and share awards (A) — not a gap in our data.

From SEC Form 4 filings. Every row links to the filing it came from. How we calculate this.
The report an officer, director or large shareholder must file after trading their own company’s stock.
Funds, trusts and other companies file the same ownership forms that executives do. Everything below is taken from those filings, with the position exactly as the filing states it.
Do not add these figures together. 2 of the positions below were reported on filings shared by several filers at once.
On a joint filing every named filer is listed against the whole position, so the same block of stock appears under each name. Those rows are marked joint.
| Owner | Reported role | Shares | Filed |
|---|---|---|---|
| PERCEPTIVE ADVISORS LLC | Director,TenPercentOwner | 5,875,851 joint | |
| PERCEPTIVE LIFE SCIENCES MASTER FUND LTD | Director,TenPercentOwner | 5,875,851 joint |
See the full ownership map — every entity that files as an owner of a US public company.
3 legal entities named in the subsidiary exhibit filed with this company’s most recent 10-K. . Filing on SEC.gov.
This is not the full list. SEC rules only require a company to name its significant subsidiaries.
Smaller entities are left out of the exhibit entirely. A short list here means a short exhibit — it does not mean the company owns nothing else. Nothing on this page is inferred: every name below is copied from the filing.
| Subsidiary | Organised in |
|---|---|
| Aldeyra Securities Corporation | United States of America |
| Helio Vision Germany GmbH | Germany |
| Helio Vision, LLC | United States of America |
A subsidiary is a separate legal entity this company controls; it is not the same thing as a brand, a division or an office. These entities do not file with the SEC in their own right, so there is no separate page to open for them.

Share count: cover page of the latest filing (dei:EntityCommonStockSharesOutstanding), taken from
Aldeyra Therapeutics, Inc.’s own filings and multiplied by our closing price.
Full method.
the share count the company itself prints on the cover of its most recent filing, as of the date it signed that filing.
We do not take a market cap from a data vendor, and we do not estimate one: the figure is a share count from Aldeyra Therapeutics, Inc.’s own SEC filings multiplied by the closing price we hold for the same stock.
