Fair value

our estimate · not analyst forecast

Not enough cash-flow history to estimate a fair value for AAOI yet.

What does this show?

Our estimate of what one share is worth based on the cash the business is expected to generate (a discounted-cash-flow model), next to today's price. Below fair value hints undervalued, above hints expensive — it's an estimate, not a guarantee.

Revenue & expenses

Q1 2026

What does this show?

How a company turns sales into profit. Revenue splits into the direct cost of sales and the gross profit left over; from that gross profit come operating costs (R&D, SG&A), tax and interest — what survives is net income. Every figure is also shown as a share of revenue, so you can compare periods and companies of different sizes.

Future

trend, not analyst forecast

Revenue · extended at 6.4%/yr

2016 · 260.7M 2028 · 549.0M projected

Dashed bars just extend the historical trend (capped at ±15%/yr) — the same growth our DCF uses. It's arithmetic on the past, not an analyst forecast; real futures bend.

What does this show?

Solid bars are history; dashed bars simply extend the past growth trend a few years forward — capped so it stays sane. It's a trend line, not an analyst forecast.

Dividend

from cash actually paid, not promises

Applied doesn't pay a dividend — Otto leaves this axis blank rather than guessing.

What does this show?

The share of profit paid back to shareholders as cash. Yield is that cash as a % of the price; the payout gauge shows how much of earnings is paid out (over ~75% can be hard to sustain).

Insiders must report within two business days. Sales are often pre-planned (10b5-1) rather than a signal — buys tend to say more.

What does this show?

Buys and sells by the company's own directors and officers, from their SEC filings. Insiders sell for many reasons, but clusters of open-market buying can signal confidence.
