$ARQ Arq now has top tier financial leadership. It would not surprise me if Arq doesn’t delay GAC build for 2 years to concentrate on PAC for PFAS and improve gross margins. If can start generating meaningful cash, as I think will happen, I think the cash internal cash generation will allow debt finance of GAC. I’m hopeful that moderate to low equity raise involved. I handicap that at 50 percent or more shot. Any meaningful settlement of engineering litigation will also be help. That or Corbin monetization. Like I said, the CFO will know how to pull levers that the prior bunch did not.

$ARQ Bought a bit more at $2.27. I could hitting below $2.10, but I can take that risk as would be a buyer there. My hesitation is more macro as I have written off GAC for next 2 years or so.

$ARQ I suspect should hold here in $2.20s until GAC expectations and unrestricted cash situation clears. I don’t see more than 10 percent downside absent something macro. However, I would not be upset if continued walk down as I hope to add at some point in September.

$ARQ Considering the magnitude of capital invested in GAC and the subsequent impairment and operational issues, why has the company not disclosed the remaining GAC carrying value, the useful life used in its impairment model, and the impairment-test headroom so shareholders can independently assess the risk of further write-downs?

$ARQ what is ARQ's realistic annual pac production capacity?

1 · Reply

F_Persimmon Aug. 13 at 3:56 PM

$ARQ If PFAS PAC reduces PFAS pollution by 5 ppt, then the number of public water systems that could benefit by ARQ’s new product is about 900. Since PAC is a lot cheaper than GAC or reverse osmosis, the product should get a lot of traction.

$ARQ Best call in a long time. CFO has got it going on. Urge listening to whole call but if only 5 minutes then Rasmus synopsis at end. Pretty confident where this is going and may offer specific thoughts later. Arq team is making lemonade out of lemons for sure though. The only negative was the dumb initial question by WTR.

$ARQ PAC for PFAS. Like the ring of that. Better margins. Hope to hear on call that can add margin and maybe $10M to $20M Multiple parties in discussions on Corbin and proof of asphalt performance enhancement. Me like. If $20M is annual EBITDA run rate, this should comfortably becomes a 3 to $4.50 stock even without Corbin developments. Nice job Rasmus and Arq team.

$ARQ Really solid quarter here. Core business remains very sturdy. Would love clarity on the go forward plans but still in progress it seems. They are flagging a wide range of options which is appropriate. If they manage 20m in ebitda this is massively undervalued especially with close to 4 bucks a share of assets (equipment, factory) on their books.

$ARQ So many positive catalysts coming here. *Highly differentiated asphalt testing. *Regulatory changes are legally forcing thousands of water facilities to buy GAC. Arq is finishing a plant expansion to supply that exact material, and their ongoing filtration testing proves their product is vastly more efficient than what's currently on the market. It places them in a perfect position to capture a massive wave of upcoming municipal water contracts. * Strong core PAC business * Substantial Insider alignment own 20% + of the float *Recent CFO higher indicates massive growth strategy unfolding.

$ARQ Rasmus is setting up lots optionally with facility upgrades. The addition of acid washing or reactivation sets up higher margins and apparently applications for semiconductors. That is not to suggest asphalt and Corbin won’t bring meaningful value consistent with Rasmus stating that the total assets have greater than $500 million in value.
