| BDO leads in slow quarter for new SEC audit clients |
The fourth quarter of 2025 marked a slowdown in new SEC audit engagements, closing out a volatile year shaped by major accounting firm mergers. Auditors added just 128 new SEC clients in the quarter, the lowest total since the first quarter of 2022. The decline follows a surge earlier in the year driven by mega-mergers between CBIZ and Marcum, and Baker Tilly and Moss Adams, which had significantly boosted second-quarter figures. Despite the slower market, BDO USA delivered a strong performance, posting 10 net new SEC audit engagements during the quarter. Those new clients represented more than $2.5bn in audited market capitalization, $823.5m in revenue, and over $21bn in assets, generating approximately $2.18m in audit fees. CBIZ CPAs recorded the highest net gain in engagements at 11, though its audited market capitalization and asset totals were lower than BDO’s. KPMG added four new engagements but led in total audited market cap ($11.5bn), revenue ($5.3bn), and audit fees ($11.1m). Other firms reporting new SEC audit wins included Assentsure, BDMP Assurance, HTL International, M&K CPAs, and LJ Soldinger Associates, each adding between three and five engagements.
