WHERE DOES THE MONEY COME FROM?
90%Grant
GrantLicense 8%Collaboration Revenue 2%
90% of all revenue comes from a single line: Grant.

That much dependence is a risk in itself: if this one line weakens, the whole company feels it directly.

Revenue last year:
$1.3M
The loss that same year:
$138.5M
For every $1 it earns, the company spends $105.

The company is still in the product-building phase: its spending runs far above its sales. That only changes once the product starts selling at scale.

THE SALES TREND
Sales have been shrinking.

An average decline of 26% a year over the last 4 years — the most striking risk in this picture. Red columns mark years that ended in a loss.

In the vault right now:
$81.6M
DEBT: $104.8M
At this pace, that money lasts less than a year.

Before the clock runs out, either sales must climb sharply or new money must come in. This is the most critical line in the whole picture.

THE PRICE TAG
MARKET VALUE / ANNUAL SALES
2.9×

This company is not turning a profit, so the market is pricing its sales instead: 2.9× for every dollar of annual revenue.

Analysts' average target sits 14,403% above today's price.

What executives did with their own stock over the last 12 months:
38 buy9 sell

Executives buying with their own money is usually read as confidence in the company’s future.

THE FIVE-YEAR JOURNEY
A long and steep decline.

An investor who bought at the very peak is down 100% today. The business is the same; what changed most is the price — and the expectations — the market pins on it.

1
THE BRIGHT SIDE · 1/2
The product is selling

Sales run at $1.3M a year. A small number, but proof the product has real buyers.

2
THE BRIGHT SIDE · 2/2
Executives are buying their own stock

Over the last 12 months, company executives reported 38 buys and 9 sells. Management buying with its own money is usually read as a good sign.

1
THE RISKS · 1/3
Small sales, big loss

A loss of $138.5M against $1.3M in annual sales. And on top of that, sales fell from the year before.

2
THE RISKS · 2/3
Trading under $1

The stock sits at $0.03. Under exchange rules, stocks that stay below $1 for too long risk being removed from the market.

3
THE RISKS · 3/3
The cash has a countdown

At the current pace of spending, the cash lasts less than a year. After that, the company needs to find new money.

FINALE · THE GRADE
grade pending

We don’t have a report card for this stock yet — the data isn’t mature enough to grade. No grade is information too: it means the evidence is thin.
