What Longeveron Inc. reports

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.

Where the employee count comes from

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.

Insiders at Longeveron Inc.

Shares is what each person last reported holding here.

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.

Rows are grouped by the role each person reports.

The role comes from the relationship boxes a person ticks on their own insider filings — officer, director, ten per cent owner — not from anything we infer. Somebody who is both an officer and a director appears once, in the combined group, so the row count still matches the figure at the top of this page. Where no filing states a role we say so instead of guessing one.

Recent insider transactions

Of the 82 rows we hold, 6 are open-market purchases (P) and 4 open-market sales (S) — the only codes we count as buying or selling.

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.

What a Form 4 is

The report an officer, director or large shareholder must file after trading their own company’s stock.

Sources and technical notes

Every figure on this page comes from filings to the U.S. SEC via EDGAR. Nothing here is estimated, and nothing is taken from press coverage or company websites.

Share count: weighted average over the reporting period (us-gaap:WeightedAverageNumberOfSharesOutstandingBasic), taken from Longeveron Inc.’s own filings and multiplied by our closing price. Not a single-day figure — treat this market cap and its rank as approximate. Full method.

What that share count means

this company did not tag a cover-page share count we could read, so the figure is the average number of shares outstanding across the whole reporting period rather than a count on any single day. If the company issued or bought back stock during the period, the true count today is higher or lower than this.

We do not take a market cap from a data vendor, and we do not estimate one: the figure is a share count from Longeveron Inc.’s own SEC filings multiplied by the closing price we hold for the same stock.
