Urgent Inquiry Regarding CERO Delisting and Short Data (Zero Availability Reported)

Urgent Inquiry Regarding CERO Delisting and Short Data (Zero Availability Reported)
soo 10-30 US Equity Public
CERO

Hello Fintel Support Team,

I’m currently monitoring CERo Therapeutics Holdings, Inc. (Ticker: CERO) on Fintel, and I noticed that the “Short Shares Availability” for US-CERO has dropped to zero as of October 30, 2025 (UTC).

I would like to confirm the following points urgently, as the stock is reportedly being delisted from Nasdaq today (October 31, 2025, U.S. time):

  1. Is the short share availability of "0" caused by full utilization of lendable shares, or due to a broker-side restriction related to the delisting and upcoming OTC transition?
  2. Once trading is suspended on Nasdaq, will Fintel continue to update short interest, borrow fee rate, and short volume data for CERO (if it moves to the OTC market)?
  3. Is there any recent data or update on the Short Squeeze Score or Market Maker assignment for CERO?
  4. Does Fintel expect that CERO will still have any tradeable volume after delisting, or will data coverage end completely?

The situation seems highly time-sensitive, so I would appreciate your clarification at your earliest convenience.

Thank you for your assistance.

Best regards,

Hi,

Let's see if I can add some thoughts to this:

  1. The number of shares available to short is provided by Interactive Brokers (IB). They unfortunately do not provide any detail around the number. Generally it's because of full utilization of lendable shares but since this is an edge case I unfortunately cannot provide any detail around this.
  2. Yes we will continue to get updates. Short Interest will be provided by FINRA on the regular schedule. IB will continue to provide short shares availability and borrow rates.
  3. Short squeeze scores are updated throughout the day as new borrow rates are available.
  4. Fintel will continue to provide coverage of CERO if it continues to trade on the OTC markets. I cannot speak to what the volume will be but be aware there are a lot of institutional funds that are not allowed to trade OTC so the volume will almost certainly decrease once it's downlisted.

I hope this helps. Wilton
