Sales don’t cover the costs; the gap drains from the cash pile every year.

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.

In the vault right now:
$235.9M
DEBT: $8.7M
At this pace, that money lasts about 3.1 years.

At this burn rate the cash pile isn’t the pressing question — for now, time is on the company’s side.

A big climb, then a hard fall.

An investor who bought at the very peak is down 85% today. The business is the same; what changed most is the price — and the expectations — the market pins on it.

2
THE RISKS · 2/2

FINALE · THE GRADE
C
47 / 100 · MoonshotScore

On our five-subject report card, SION sits behind the class. A low grade doesn’t mean “doomed” — it means “big claim, small proof.”

The takeaway: SION is a high-risk stock — not yet profitable, and its future rides on its product catching on.

The total grade weighs these five subjects against the sector — it isn’t a simple average of the five.

Analysts’ average target sits above today’s price, yet the valuation grade (45/100) says the stock isn’t cheap.
