Backlog

Backlog represents the future sales the Company expects to recognize on firm orders it receives and is equivalent to the Company’s remaining performance obligations at the end of each period. It comprises both funded backlog (firm orders for which funding is authorized and appropriated) and unfunded backlog. The Company's backlog excludes unexercised contract options. As of June 30, 2023, the Company had $262.5 million of backlog, which represents the transaction price of executed contracts less inception to date revenue recognized. The Company expects to recognize revenue relating to its backlog, of which a portion is recorded in deferred revenue in the unaudited condensed consolidated balance sheets, of $40.1 million, $43.9 million, and $178.5 million in the six months ending December 31, 2023, fiscal year 2024, and thereafter, respectively.
