Fluctuations in price prior to the DA announcement (whether good or bad) are entirely irrelevant. $PASO could drop to .005 and it would make zero difference (assuming it didn't drop due to leaked bad news) because if the DA gets signed, $PASO will be taking on the value of CLX Health, period. The PPS in the meantime is inconsequential.
In my opinion the deal is still on and CLX and PASO cannot discuss it while it is being finalized, but CLX is providing clear hints in order to maintain stability for all players involved while keeping the PPS from plummeting prior to their announcement.
If I remember correctly, they tweeted out "Roadmap is still intact!", then deleted the tweet, then immediately afterward posted the same message, but this time while retweeting an old tweet that detailed their roadmap (which explicitly includes an RM with PubCo). This was an obvious method of communicating the status of the RM without defying their NDA, or whatever other gag-order they have in place.
Keep in mind that CLX has been wildly transforming over these last several months and laying a foundation for the future growth of Health Pass. Additionally, it is much easier for private companies to finalize partnerships that public companies, so it would make sense that they are waiting to get everything in order prior to going public. Until we hear otherwise, we have no reason to believe that the deal has been terminated.
