What's Driving ATEX's Business? Latest 10-Q Breakdown

AI-extracted from the 10-Q filed 2026-08-11 — Q1 FY2027 (quarter ended June 30, 2026). Every figure is machine-verified against the filing text on SEC EDGAR.

Biggest Revenue Drivers

Largest Expense Items

General and administrative$9,624K-8% YoY

Lower stock compensation expense and reduced headcount costs, partially offset by higher travel and entertainment.

Sales and support$1,911K+28% YoY

Higher headcount and stock compensation costs, plus increased marketing expense.

Product development$1,220K+9% YoY

Technology and product development functions supporting spectrum offerings.

Depreciation and amortization$101K-19% YoY

Depreciation of property, equipment and right-of-use assets.

Margins: Operating loss of $0.2M in Q1 FY2027 vs. operating income of $22.5M in Q1 FY2026, driven by non-recurring gains on narrowband-to-broadband license exchanges ($10.7M in Q1 FY2027 vs. $33.9M in Q1 FY2026) rather than core margin deterioration. Spectrum revenue growth was offset by reduced one-time exchange gains.

Watch Items from the Filing

Customer concentration: Xcel Energy, Evergy, and TECO each represent >10% of quarterly revenue; any delivery delays or contract terminations could materially impact revenue.
Maximum potential liability under Xcel Energy guaranty is $66.5M (reflecting performed obligations through June 2026); delivery of broadband licenses must continue through 2029 or refunds required.
Deferred revenue of $174.9M as of June 30, 2026 represents $197.8M in remaining performance obligations over up to 30 years; cash collection contingent on timely spectrum clearing and license delivery.
Spectrum acquisition and retuning costs of $39.0M in committed future payments to incumbents; timing and success of FCC approvals could impact cash flow.
Cash and equivalents increased to $116.0M from $98.5M; $226.7M remaining authorization under share repurchase program (expires September 21, 2026) provides capital flexibility.
