Completed session

IEX historical data reflects IEX activity only and is presented as a source-scoped reference point, not as consolidated U.S. market history. Prices are unadjusted. Price returns exclude dividends and are not total returns. Historical statistics appear only when the retained source-session chain is complete and no split-like share-basis discontinuity is detected for that calculation window.

About this market data

IEX historical data reflects IEX activity only and is presented as a source-scoped reference point, not as consolidated U.S. market history.

Screened reference metrics use K9-qualified IEX reference history and only explicitly registered positive split events. They do not assert complete split history, consolidated U.S. market performance, or canonical adjusted prices.

Data provided for free by IEX. By accessing or using IEX Historical Data, you agree to the IEX Historical Data Terms of Use.

The raw chart can show a discontinuity around a stock split because it is intentionally unadjusted. The screened metrics use only explicitly registered positive split events and do not assert complete split history.

Fundamental lens

Four transparent questions from retained financial evidence. Each result stands on its own; Grizzly Bulls does not combine them into a score, ranking, or recommendation.

Profitability
Profitable
Is trailing-twelve-month net income positive?

Trailing-twelve-month net income is positive. As of 2026-06-30.

Net income (TTM): $78.5M
Cash generation
Positive free cash flow
Is trailing-twelve-month free cash flow positive?

Trailing-twelve-month operating cash flow less capital expenditures is positive. As of 2026-06-30.

Free cash flow (TTM): $152.9M
Liquidity
Current assets above liabilities
Do reported current assets cover reported current liabilities?

Reported current assets exceed reported current liabilities on the latest comparable retained balance sheet. As of 2026-06-30.

Current assets: $631M · Current liabilities: $263.2M
Recent operating direction
Unknown
What changed in the latest comparable reported results?

Comparable retained change history is not available through this reader.

How this lens works

Profitability uses only the sign of retained trailing-twelve-month net income. Cash generation uses only the sign of retained trailing-twelve-month free cash flow, defined as operating cash flow less capital expenditures.

Liquidity compares current assets with current liabilities only when both are retained for the same reporting date. It does not infer liquidity from differently dated balance sheets.

Recent operating direction uses the latest supported material financial event when comparable history exists. The existing change methodology requires at least a 10% absolute change or a sign/zero transition and compares quarterly results only with the same fiscal quarter year over year.

Descriptive decision support only. No composite score, hidden weighting, cross-company rank, or investment recommendation is produced.

Statistics

Reproducible trailing, quarterly, and annual statistics from retained SEC financials. Growth and return measures appear only when the required reporting periods align; missing denominators are omitted rather than estimated.
