Evidence signals

  • 1 filing risk check flagged

    Flagged areas: Solvency & liquidity.

    Why this surfaced

    The full financial analysis shows each value, threshold, and sector limitation.

  • Revenue expanded

    Latest reported annual revenue changed +20.3% from the prior reported annual observation.

    Why this surfaced

    Direction threshold: above +2% constructive; below -2% caution; otherwise monitor. This is not labeled one-year growth when filing periods have a gap. Period end 2025-12-31.

  • Operating margin improved

    Operating margin changed +7.3 percentage points from the prior annual period.

    Why this surfaced

    Direction threshold: more than +1 percentage point constructive; below -1 point caution. Period end 2025-12-31.

  • Free cash flow was positive

    Latest reported free cash flow was $116M.

    Why this surfaced

    Free cash flow = operating cash flow minus capital expenditures; positive is supporting evidence, not a valuation conclusion. Period end 2025-12-31.

Each filer's latest fiscal year as stored by the nightly crawl; fiscal year ends differ across the universe. A metric ranks only filers for which it is computable from filed facts. Ties split; a rank reads "better than N% of filers" in the metric's own direction. Descriptive and educational, not a rating.

Per fiscal year from filed facts: cash conversion = operating cash flow / net income (net income > 0); cash-flow accrual ratio = (net income - operating cash flow) / average total assets; balance-sheet accrual ratio = change in net operating assets / average net operating assets, NOA = (assets - cash) - (liabilities - debt). Descriptive; a missing input yields a missing ratio. High accrual ratios and cash conversion well below one are the measures the accruals literature associates with less persistent earnings; they are screens to read the cash-flow statement with, not conclusions. The per-year series is part of Pro risk analysis.

Point-in-time ledger

first-reported vs latest filing · periods since 2020-01-01 · 0 changed periods

No period on file has changed between its first report and the latest filing carrying it.

First filing reporting each period vs the latest filing carrying it (10-K and 10-Q only, periods since 2020, the extractor's winning tag per concept); a change under 0.5% is treated as rounding. A change can be a restatement, a reclassification or a re-tagging in a later comparative column; the two filings are linked so the reader can see which. Descriptive, not a verdict.

Fair value · 2,189 characters as filed

Fair Value Measurements We measure our cash equivalents and marketable securities at fair value on a recurring basis. Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. We utilize the following three-tier value hierarchy, which prioritizes the inputs used in measuring fair value: Level 1 Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 Observable inputs other than quoted prices included in Level 1 for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-driven valuations in which all significant inputs and significant value drivers are observable in active markets. Level 3 Unobservable inputs to the valuation derived from fair valuation techniques in which one or more significant inputs or significant value drivers are unobservable. The fair value hierarchy also requires us to maximize the use of observable inputs, when available, and to minimize the use of unobservable inputs when determining inputs and determining fair value. The following tables sets forth our financial assets measured at fair value on a recurring basis based on the th

"Income Taxes The following table presents income taxes and the effective tax rates for the periods indicated (in thousands, except percentages): Three Months Ended Six Months Ended June 27, 2026 June 28, 2025 June 27, 2026 June 28, 2025 Income (loss) before income taxes $ 23,595 $ 3,427 $ 38,827 $ 437 Income taxes $ 6,484 $ 3,626 $ 10,506 $ 5,423 Effective tax rate 27.5 % 105.8 % 27.1 % 1,241.0 % Our income taxes for the three and six months ended June 27, 2026 were determined using an estimated annual effective tax rate adjusted for discrete items that occurred during that period as required under Accounting Standards Codification (ASC) 740-270, Accounting for Income Taxes in Interim Periods . We have historically recorded interim provision for income taxes by applying ASC 740-270. For the three and six months ended June 28, 2025, due to the level of forecasted provision for income taxes relative to the forecasted pre-tax income used in computing the effective tax rate, the effective tax rate was highly sensitive to fluctuations in pre-tax income and did not provide a reasonable estimate for income taxes in the interim period. As such, we computed the provision for income taxes for the three and six months ended June 28, 2025 using an actual year-to-date tax calculation. Our effective tax rate for the three and six months ended June 27, 2026 is different from the statutory federal corporate tax rate of 21% primarily due to state taxes, the effect of non-deductible stock-bas

Revenue recognition · 2,812 characters as filed

Revenue from Contracts with Customers Contract Asset Contract assets include amounts recognized as revenue prior to our contractual right to bill the customer. Amounts are billed in accordance with the agreed-upon contractual terms. Contract assets were $4.9 million as of June 27, 2026 as compared to $4.8 million as of December 31, 2025, and are included in prepaid expenses and other current assets and long-term other assets on the Condensed Consolidated Balance Sheets. We expect to recognize 38% of the June 27, 2026 balance during 2026. Contract Liability Deferred revenue was $56.0 million, $50.5 million and $50.3 million as of June 27, 2026, March 28, 2026 and December 31, 2025, respectively. The increase in the deferred revenue balance for the three and six months ended June 27, 2026 was driven by cash payments received or due in advance of satisfying our performance obligations offset by $13.3 million and $18.2 million of revenue recognized that was included in the deferred revenue balance at the beginning of each respective period. Remaining performance obligations (RPOs) represent contractual commitments that have not yet been fulfilled, which include deferred revenue and amounts that will be invoiced and recognized as revenue in future periods but exclude variable consideration where the monthly invoicing is based on usage or where actual usage exceeds the minimum commitment. RPOs were $386.4 million as of June 27, 2026, and we expect to recognize as revenue 42% of thi

Segment reporting · 3,372 characters as filed

Segment Information We develop, market and sell an appliance-based broadband platform, cloud and managed services. There are no segment managers who are held accountable for operations, operating results and plans for levels or components below our unit level. Accordingly, we are a single reporting segment and operating unit structure. Our chief operating decision maker (CODM) is our Chief Executive Officer, who reviews financial information presented on a Company-wide basis, for purposes of allocating resources and evaluating financial performance. The CODM assesses the performance of the single segment and allocates resources based on revenue and measures derived from gross margin and operating loss that is reported in the Condensed Consolidated Statements of Comprehensive Income (Loss). In addition, the CODM uses a measure derived from operating expenses in the Condensed Consolidated Statements of Comprehensive Income (Loss) to monitor budget versus actual results to determine the entitys and managements performance. We do not have intra-entity sales or transfers. The measure of the single segment assets is the consolidated assets in the Condensed Consolidated Balance Sheet. The accounting policies of the single segment are the same as described in the significant accounting policies. Geographic Information: A summary of revenue disaggregated by geographic region based upon the location of the customers was as follows (in thousands): Three Months Ended Six Months Ended Jun
