Total return (dividends reinvested) vs the market, from quarter-end prices.
Above 0 = ahead of the S&P 500 since the window start; below 0 = behind. Rising means it's pulling ahead.
How far the stock fell below its prior peak. Deeper, longer drawdowns = a rougher ride to the same return.
Quarter-end, dividend-adjusted (total return). Beta & volatility from quarterly returns (annualized). Benchmark is the S&P 500 (SPY total return). Annual returns compound the quarters ending in each calendar year; the first and last years in a window may be partial. Past performance doesn't predict future results.
A reverse discounted cash flow is not shown for a company with no positive EBITDA.
No positive EBITDA in the recent record, so there is no return on capital to compare against its cost. Equity is negative, so debt/equity and ROE invert their signs and read as the opposite of what they mean.
Classified from the filings: EBITDA negative in each of the last 2 years.
Ranked against 12 sector peers with collected financials. Valuation from latest close × latest fiscal-year fundamentals; 13F conviction as of 2026-09-30.
Percentile is “goodness” within the peer set (100 = best). For valuation and leverage that means cheaper / less-levered ranks higher.

Peers = companies sharing GLTK's sector (Telephone Communications (No Radiotelephone)) with collected SEC financials. Multiples use the most recent end-of-day close and latest fiscal-year fundamentals (trailing, not forward). Missing cells mean the peer never reported that line item, has no collected price, or has a non-positive denominator. Not investment advice.
What the company returns to shareholders — and whether it's covered by cash.
No dividend to cover. Last year: $0 dividends + $0 buybacks = $0 returned on -$1.8M FCF.
Yields use the latest fiscal-year dividends/buybacks over current market cap. Dividends and buybacks from the SEC cash-flow statement; payout coverage vs net income and free cash flow. Educational — not a recommendation.
How management deployed cash over 5 years — and what it earned on reinvestment.
A reinvestment story — most cash went back into growth rather than to shareholders.
Reinvestment has been productive — operating income grew well per dollar put in. Current ROIC on all capital: 53%. Rough measure (includes maintenance capex).
Cash uses aggregated from the SEC cash-flow statement over 5 fiscal years. "Return on reinvestment" is a rough proxy — operating-income change ÷ cumulative CapEx + M&A — and includes maintenance capex. Educational — not a recommendation.

Is the profit real, and how strong is the balance sheet?
FY2025 · every deduction from revenue to net income
DuPont — the three levers
ROE 46% against ROIC 53% — -6% of the return on equity comes from leverage and buybacks rather than from the operating business.

Latest year: profit growth vs revenue growth
Profit and sales moved in opposite directions this year.
Each line as % of revenue — the trend in color
| % of revenue | FY2021 | FY2022 | FY2023 | FY2024 | FY2025 |
|---|---|---|---|---|---|
| Cost of Revenue | 104.1 | 100.8 | 100.6 | 100.5 | — |

| Net Income | -60.6 | -106.9 | -78.4 | -16.1 | -52.3 |
Green = margin-favorable vs the row's own range · red = unfavorable.
The metrics that matter, over time
A 30-second read on GLTK: price, valuation and headline fundamentals from SEC filings. The four questions at the top of the page are where the judgements live.
How much the company owes, how it's trended, and how comfortably it's serviced.
Insufficient EBITDA/debt history.
Green ≤ 1.5× · amber ≤ 3× · red > 3× (leverage relative to cash earnings).
Thin coverage — earnings barely cover interest. Effective rate ~142.9% on $1.5M of debt. Interest last disclosed in FY2023 (no longer broken out).
Cash of $529K is below short-term debt of $2.9M — relies on refinancing/operations.
Mostly short-term debt (balance-sheet current vs non-current split). A year-by-year maturity schedule wasn't disclosed for this issuer.
Debt, cash, interest and equity from the SEC balance sheet & income statement. Effective rate = interest ÷ average debt. Educational — not a recommendation.
No positive operating income in the last three years, so there is no return on capital to compare against its cost.
| Fiscal year | Gross margin | Operating margin | Net margin |
|---|---|---|---|
| FY2021 | -4.1% | -61.4% | -60.6% |
| FY2022 | -0.8% | -95.2% | -106.9% |
| FY2023 | -0.6% | -98.7% | -78.4% |
| FY2024 | -0.5% | -22.2% | -16.1% |
| FY2025 | not reported | -16.9% | -52.3% |
No material counter-signal in the checked set: ROIC vs WACC spread, 5-year spread history, gross margin trend, operating margin trend, net margin against 3 years ago, revenue growth, ROIC ex-goodwill gap.
Missing from our data, so excluded from this answer: tax_rate.
Fewer than three profitable years with a cash flow statement, so cash conversion cannot be judged.
No material counter-signal in the checked set: FCF / net income over 3 and 5 years, Sloan accruals, SBC as a share of revenue, SBC as a share of operating cash flow, SBC-adjusted free cash flow, free cash flow per diluted share, buybacks against SBC issued, capex vs depreciation, free cash flow against revenue, share count since the first year on file, cash conversion cycle (DSO, DIO, DPO), receivables growth against revenue growth.
Missing from our data, so excluded from this answer: 3 years of cash flow.
Debt is present but there is no positive EBITDA or no reported interest expense, so coverage cannot be measured.
Balance sheet at 2025-12-31. Undrawn revolving credit is not shown: the tag is collected but not yet mapped through to the API.
No material counter-signal in the checked set: net debt / EBITDA, interest coverage, stressed coverage, maturity schedule vs cash and one year of FCF, liquidity ratios.
Missing from our data, so excluded from this answer: ebitda, interest_expense.
At $5.00, free cash flow must compound 77.57%/yr for 10 years. It has no positive compounding record to compare against.
The implied rate of 77.57% has not been achieved in any of the last 1 years.

How a revenue dollar becomes profit — FY2025
