Shares shifted sharply as AeroVironment posted a fiscal fourth-quarter blowout that sent the stock up 6.4% to $173.00, extending a volatile run since earnings landed on June 30. The defense drone maker delivered numbers that crushed Wall Street forecasts on every major line — yet the gap between the headline strength and the accounting reality underneath is the core question shareholders now face.

Revenue More Than Doubled, Powered by Drones and Deals

Quarterly revenue more than doubled to $641.6 million, well ahead of the $556 million analysts had anticipated, compared with $275.1 million in the same period a year ago.

On a pro forma basis, organic growth was 31%, driven primarily by the Autonomous Systems segment — the unit that sells loitering munitions and other battlefield drones. Higher-margin autonomous systems products comprised 77% of quarterly revenue , giving the quarter a favorable profit mix. For shareholders, the sheer scale of top-line acceleration validates the company's aggressive acquisition strategy, including the BlueHalo merger.

A $1.2 Billion Backlog Signals Staying Power

Funded backlog reached $1.2 billion, about 65% higher than the $726.6 million reported a year earlier.

The trailing 12-month book-to-bill ratio stands at 1.4 times , meaning orders are outpacing shipments — a classic indicator of durable demand. A $500 million U.S. Army contract for counter-drone systems through 2029 further strengthens long-term revenue visibility.

The Earnings Beat Is Real — But So Are the Acquisition Costs

Non-GAAP EPS of $1.84 exceeded the $1.48 analyst estimate by 24.3%. However, full fiscal 2026 produced a GAAP net loss of $265.1 million, mainly due to $240.7 million of goodwill impairment and heavy amortization from acquisitions. These are non-cash charges that don't drain the bank account today, but they reflect the premium prices AeroVironment paid for its deals — and could signal overpayment if growth disappoints.

Fiscal 2027 Guidance Lags the Street on Earnings

Management's fiscal 2027 EPS guidance of $3.02 to $3.34 fell substantially below the $4.00 Wall Street consensus.

Revenue guidance of $2.125–$2.225 billion still implies continued growth , but the softer profit outlook means integration costs and amortization will keep weighing on reported earnings. Analysts at Clear Street, KeyBanc, and BTIG cut price targets yet maintained buy-equivalent ratings, stressing that demand is "delayed, not broken."

The bottom line: AeroVironment's demand story is as strong as ever, but investors are betting on future profits from a balance sheet still digesting expensive acquisitions.
