As a recent retiree you've been around the block a few times to be sure.
Investor Relations is the branch of a publicly traded company responsible for keeping the investment community abreast of developments ongoing as well as sudden surprises. And, of course, it's IR that issues all press releases as well as info contained in all SEC filings---8-ks. 10-ks, and "sudden onset" matters that do crop up every now and then.
There is only one way to address perceived insufficiencies such as you bring up:
Contact Investor Relations.
Mind you I'm not saying you shouldn't bring the matter up here for I completely understand your motivation/vexation. However, I headed up IR for a couple of companies prior to retiring and I was tasked with the responsibility of addressing share holder concerns. You should not have to go to the well only to walk away still thirsty.
However, It's not within the purview of Avita to remedy the situation.
Now, there are two ways a company can approach Investor Relations:
1. In-house IR.
2. Hire an outside agency.
In-house IR can be in the form of someone brought on board specifically to handle such things. That person is likely a Vice President of IR for the company, specializing in all things specific to trading statistics, press releases (including writing them) and attending regularly held meetings with the CEO, President of the company, and the Chairman. All publicly released papers must gain the aforementioned as well as other BOD approvals and absolutely critical: Company legal counsel.
Now, that's the in-house variety of IR coverage.
Let's take a moment and examine the outside IR:
It's an individual working for a non-associated company often without prior sector-relations affiliation. I headed up IR for a couple of energy companies and would NOT have been suitable to head up a biotech IR department. For the same reason, a company's CFO or accountant--=-in my opinion---would not be a smart pick.
It's often said that you get what you pay for. I'm not in a camp advocating the hiring of an outside IR individual. As I see it, you'd be hiring an out-house head. Bring in the guy from the head to be the head? lol
A good IR person lives and breathes the company he represents. He/she sees to the dissemination of materials describing initiatives, handles all public addressing of critical matters for the company and is the official spokesperson for the company. And the IR head person writes all public communication including PR's and SEC filings. Above all, that individual will always be a capable writer able to incorporate a touch of humor here and there so as to not come across as untouchable or arrogant.
You're wishing for more insight re. ongoing concerns such as the Japanese approval and other things. I suggest contacting the designated Avita IR person. I read between the lines and word-by-word dissect each and every bit of paper coming out from the company as I'm sure you do also. I understand things take time and the pandemic is making things considerably more difficult. But to be perfectly clear---Avita may not even be aware that IR is failing to earn a passing grade. Discussion here won't change it but contacting the BOD---if pursued by enough of us---will likely produce a desired action.
