  • G&A expenses were $4.5 million for Q3 2025, reflecting lower legal, audit, and recruiting costs; for the nine months ended September 30, 2025, G&A expenses decreased 6% year-over-year to $14.3 million.

One of the very few apps you could call perfect. If something was to add to it, maybe the share price of the company when you search for it, but it's already excellent.
