Achieved critical strategic milestone with the execution of its first supply contract for Granular Activated Carbon (“GAC”) product with a new customerAgreement reflects 5 million pounds/year of GAC with delivery commencing in Q1 2025; Arq’s Red River GAC plant is on target to complete commissioning in Q4 2024Encouraging ongoing discussions with additional potential customers for further GAC contracts; Arq expects additional near-term announcementsGREENWOOD VILLAGE, Colo., May 08, 2024 (GLOBE NEWSWIRE) — Arq, Inc. (NASDAQ: ARQ) (the “Company” or “Arq”), a producer of activated carbon and other environmentally efficient carbon products for use in purification and sustainable materials, today announced the execution of its first sales contract for delivery of GAC produced from its unique purified bituminous coal waste derived feedstock at its strategic Red River facility.Under the terms of the agreement, the new Arq customer, a North American solutions provider of water and wastewater treatment and PFAS capture technologies, will purchase a forecasted 5 million pounds of GAC product in 2025, reflecting approximately 20% of the facility’s initial expanded nameplate capacity of 25 million pounds per year.Bob Rasmus, CEO of Arq commented, “Today’s announcement reflects a critical milestone in the ongoing strategic transformation of Arq. Our first GAC supply contract represents third party validation of our strategy and our GAC solutions. The contract demonstrates follow through on our commitment to stakeholders and the hard work of our entire team. The contract pricing is attractive, and represents a multiple of our average PAC pricing. This amplifies our confidence in our strategy while further de-risking the strategic development of Red River. We now have approximately 20% of our nameplate Red River capacity now contracted nearly 9 months ahead of commissioning. We remain in advanced levels of dialogue with a range of potential counterparties. Based on those discussions, we remain in an enviable and exciting position to contract the remainder of our capacity prior to initiation of production at attractive rates.”Garrett Chandler, VP Sales of Arq added, “Securing this strategic partner as our first GAC customer is an exciting development as we aim to deliver successfully into a pipeline of sales growth.

You’re still not doing a proper backup or you’re not completely satisfied with Time Machine? Arq Backup should make your life a lot easier.Which Backup Program for Mac? This one.Arq Backup is a very stable program that works wonderfully. What it can’t do: create bootable images. So it only serves to backup your user folder (or other freely configurable sources). In addition, it costs about 50 dollars, lifetime upgrades 30 dollars more. Fair enough: the license is per user, so you can backup iMac, MacBook and Tinker-Mac with Arq. First of all: the price is very fair for the functions and in case of a data loss it’s a gift anyway.What is the difference to other backup programs (of which we have listed some good ones here)? Basically, Arq is specialized in online backups. Of course local folders also work (also on a NAS), but the intended purpose is an online backup. And here comes a serious advantage: Arq encrypts the backups before they leave your computer. So if you’ve always been afraid to make backups in the cloud, you’ve now found a tool that keeps your data private, no matter where they end up (assuming, of course, that you choose a secure and long password).In addition to the local data options, Arq offers compatibility with almost all online services:Amazon DriveAWS (S3 and GlacierBackblaze B2DropboxGoogle DriveGoogle Cloud StorageOneDriveSharePointWasabiall S3 compatible offersAnd for your own projects alsoSFTPSo if you already make a local backup and are looking for a solution to a good online backup, then we can highly recommend Arq to you.Easy to operate, stable and reliable in operation, indispensable in case of doubt.The setup is simple, the design and structure dry and unobtrusive. This is exactly what you expect from a program that you entrust with your data and whose skills usually work in secrecy.To create your backup, enter the appropriate data for your service, add the folder to be backed up (usually your home folder) and let the program do its magic. Restoring the data is similar: You can browse the directory tree by date and select the appropriate folders or files to find your way back to the hard disk.It should not go unmentioned that Arq uses a different format for storing the data, which is independent of the file system of the storage location. This allows Arq to save all metadata of macOS files such as color labels. Many backup programs simply store the files on file system level and then have to mediate between macOS APFS and others. This is not the case with Arq and is another unique feature that makes the program the first choice when it comes to reliably backing up important data.
