The effectiveness of this massive resale shelf creates a significant overhang that will likely pressure PRTS shares. Monitor for any selling stockholder notices or Form 144 filings indicating actual sales. The prior S-3 from June 8 (1M shares) plus this one (32.5M shares) represent an enormous potential overhang relative to the $55M market cap — any actual selling could drive material downside.
