What it owns and what it owes

Both on one scale, because both are money — the bar that is taller is the one that matters.

Cash and debt

Cash & InvestmentsTotal Debt

Cash counts short-term investments, not just the bank balance — technology companies park most of it in marketable securities, and leaving those out understates it several times over. Debt includes lease obligations.

Where the money goes

Cost of RevenueR&D ExpenseSG&A Expense

Only the three costs filers report consistently. Anything a company does not break out sits outside these bands, so the stack is not the whole cost base.

The rest of the series

Not on the overview because five charts is as much as one decision needs — but here in full, on one period switch. Each bar sums the four quarters ending there — a full year, brought up to today.

Total Revenue

$41KQ4 2025+105.0%

1Y: +105.00%2Y: -90.38%5Y: -99.50%

Everything the company sold, before any costs. Each bar sums the four quarters ending there — a full year, brought up to today.

EBITDA

-$100.13MQ2 2026-3.4%

1Y: -6.24%2Y: +8.95%5Y: -46.45%

Operating profit before depreciation and amortisation — approximated from operating income, because no depreciation tag is reported consistently enough across filers to do better. Treat it as indicative. Each bar sums the four quarters ending there — a full year, brought up to today.

Profit

-$91.76MQ2 2026-0.7%

1Y: -4.57%2Y: +9.46%5Y: -34.78%

What was left after every cost, including tax. Each bar sums the four quarters ending there — a full year, brought up to today.

Profit margin

-214,861.0%Q4 2025+48.8%

How much of every dollar of sales the company keeps as profit. A grocer keeps a few cents; a software company can keep half. Each point covers the four quarters ending there — a full year, brought up to today.

Free Cash Flow

-$76.56MQ2 2026-0.9%

5Y: -4.38%

Cash left over after running and maintaining the business. Each bar sums the four quarters ending there — a full year, brought up to today.

Profit per share

-$0.77Q2 2026+16.3%

1Y: +34.75%2Y: +53.05%5Y: +54.44%

The same profit, split across every share. If this lags the profit chart above, the company is issuing shares and your slice is getting smaller. Restated onto today’s share count, so stock splits do not show as jumps. Each bar sums the four quarters ending there — a full year, brought up to today.

Shares outstanding

126.29MQ2 2026+25.9%

How many shares the profit is divided across. Rising is dilution; falling is the company buying itself back. Restated onto today’s basis, so splits do not show as jumps. Each point covers the four quarters ending there — a full year, brought up to today.

Price to earnings

439.0xQ4 2019-95.3%

Paid per unit of yearly profit. Periods with a loss, or profits too small for the ratio to mean anything, are left out — the line breaks rather than drawing through them. Each point covers the four quarters ending there — a full year, brought up to today.

Dividends paid

$200.25MQ1 2017

No TTM figures — showing Quarterly

Cash handed to shareholders. A flat line at zero means the company pays none. Each quarter on its own, so seasonal highs and lows are visible.

About this data

Everything above comes from Altimmune, Inc.’s own filings with the SEC, as reported. No estimates, no analyst figures, nothing adjusted.

Splits applied: 33:1 on Sep 13, 2018. Per-share history is restated onto today’s basis, so a split does not appear as a cliff.

Share-count jumps we cannot explain: 1.61x around Dec 31, 2021. No split accounts for these, so nothing was adjusted — most often it is real dilution rather than a data problem, which is why it is flagged and not corrected.

Not reported by this filer: Cost of Revenue, Gross Profit, Non-interest Income, Non-interest Expense, Provision for Credit Losses, Deposits, Loans, Inventory, Borrowings (total), Finance Lease (current), Finance Lease Liabilities (total), Finance Lease (noncurrent), Amortization of Intangibles, and Share Repurchases. Companies choose which XBRL tags to use, and anything untagged cannot be recovered — so these are blank rather than guessed.
