On November 21, 2019, Alvogen filed an amended answer and counterclaims asserting monopolization, attempted monopolization, and conspiracy to monopolize against us and Indivior under federal and New Jersey antitrust laws.

Reckitt Benckiser Pharmaceuticals, Inc. and MonoSol Rx, LLC v. BioDelivery Sciences International, Inc. and Quintiles Commercials US, Inc. (BDSI 2014 Lawsuit) On September 22, 2014, the Company and RB initiated a lawsuit against BioDelivery Sciences International, Inc. ("BDSI") and Quintiles Commercial US, Inc. (“Quintiles”) asserting infringement of U.S. Patent No. 8,765,167 (the "’167 patent”) in the District of New Jersey (Civil Action No. 3:14-cv-5892). On July 22, 2015, the case was transferred to the Eastern District of North Carolina. BDSI filed requests for inter partes review (“IPR”) of the ’167 patent before the Patent Trial and Appeal Board (“PTAB”), and on May 6, 2016, the Court stayed the case pending the outcome and final determination of the IPR proceedings. On March 24, 2016, the PTAB issued final written decisions finding the ’167 patent was not unpatentable, and the United States Court of Appeals for the Federal Circuit (“Federal Circuit”) remanded those decisions for further proceedings before the PTAB. Following the PTAB’s February 7, 2019 decision on remand denying institution, BDSI appealed that decision to the Federal Circuit. The Federal Circuit granted the Company's motion to dismiss the appeal, and denied BDSI’s request for rehearing en banc. BDSI filed a petition for writ of certiorari to the Supreme Court of the United States (“Supreme Court”), which the Supreme Court denied on October 5, 2020. On April 15, 2021, the Court lifted the stay of the litigation in the Eastern District of North Carolina. On April 29, 2021, BDSI filed a renewed motion to dismiss the complaint. In response, the Company and RB filed an amended complaint on May 18, 2021, which, among other things, removed Quintiles as a defendant. On June 3, 2021, BDSI filed a notice withdrawing its motion to dismiss the original complaint. On July 7, 2021, the Court entered a scheduling order in the case. Under the current scheduling order, the parties have completed their exchange of preliminary infringement and validity contentions, have completed claim construction briefing, and are proceeding with fact discovery. The Court may schedule a claim construction hearing, and the remainder of the schedule is dependent on the timing of the Court’s ruling on claim construction. The Company is not able to determine or predict the ultimate outcome of this proceeding or provide a reasonable estimate or range of estimates of the possible outcome or losses, if any, in this matter. Aquestive Therapeutics, Inc. v. BioDelivery Sciences International, Inc. On November 11, 2019, the Company initiated a lawsuit against BDSI asserting infringement of the ’167 patent in the Eastern District of North Carolina. On April 1, 2020, the Court denied BDSI’s motion to stay and its motion to dismiss the complaint. On April 16, 2020, BDSI filed its Answer and Counterclaims to the complaint, including counterclaims for non-infringement, invalidity, and unenforceability of the ’167 patent. On May 7, 2020, the Company filed a Motion to Dismiss BDSI’s unenforceability counterclaim and a Motion to Strike BDSI’s corresponding affirmative defenses. On May 28, 2020, BDSI amended its counterclaims and filed an Answer and Amended Counterclaims, which included additional allegations in support of BDSI’s unenforceability counterclaim. On June 25, 2020, the Company filed a Motion to Dismiss BDSI’s Amended Counterclaim for unenforceability and a Motion to Strike BDSI’s corresponding affirmative defense of unenforceability, which BDSI opposed. On March 16, 2021, the Court issued an order granting-in-part and denying-in-part Aquestive’s motion to dismiss BDSI’s counterclaims asserting unenforceability of the ’167 patent. Aquestive filed its answer to the remaining portions of BDSI’s counterclaims on April 6, 2021. BDSI also filed on April 6, 2021 a renewed motion to dismiss Aquestive’s complaint, which Aquestive opposed. On August 10, 2021, the Court entered an order denying BDSI’s motion to dismiss. On July 7, 2021, the Court entered a scheduling order in the case, including the same operative dates as the Court included in the scheduling order for the BDSI 2014 Lawsuit described above, and the parties are proceeding under that same schedule. The Company is not able to determine or predict the ultimate outcome of this proceeding or provide a reasonable estimate or range of estimates of the possible outcome or losses, if any, in this matter. Antitrust Litigation State of Wisconsin, et al. v. Indivior Inc., Reckitt Benckiser Healthcare (UK) Ltd., Indivior PLC, and MonoSol Rx, LLC, On September 22, 2016, forty-one states and the District of Columbia, or the States, brought a lawsuit against Indivior and us in the U.S. District Court for the Eastern District of Pennsylvania alleging violations of federal and state antitrust statutes and state unfair trade and consumer protection laws relating to Indivior’s launch of Suboxone Sublingual Film in 2010 and seeking an injunction, civil penalties, and disgorgement. After filing the lawsuit, the case was consolidated for pre-trial purposes with the In re Suboxone (Buprenorphine Hydrochloride and Naloxone) Antitrust Litigation, MDL No. 2445, or the Suboxone MDL, a multidistrict litigation relating to putative class actions on behalf of various private plaintiffs against Indivior relating to its launch of Suboxone Sublingual Film. While the Company was not named as a defendant in the original Suboxone MDL cases, the action brought by the States alleges that the Company participated in an antitrust conspiracy with Indivior in connection with Indivior’s launch of Suboxone Sublingual Film and engaged in related conduct in violation of federal and state antitrust law. The Company moved to dismiss the States’ conspiracy claims, but by order dated October 30, 2017, the Court denied the Company's motion to dismiss. The Company filed an answer denying the States’ claims on November 20, 2017. Daubert motions were filed on September 28, 2020, and oppositions were filed on October 19, 2020. On February 19, 2021, the Court issued an order denying all Daubert motions. On March 8, 2021, Aquestive filed a motion for summary judgment, and briefing on summary judgment motions was completed on May 28, 2021. The hearing on Aquestive’s motion for summary judgment was held on May 18, 2022 and, on October 19, 2022, the Court entered an order dismissing all claims against the Company in the lawsuit. The order dismissing all claims against the Company could be appealed by the plaintiffs in this case. The Company is not able to determine or predict whether the plaintiffs will appeal the order or the ultimate outcome of this proceeding or provide a reasonable estimate or range of estimates of the possible outcome or loss, if any, in this matter.

Centene Corporation, Wellcare Health Plans, Inc., New York Quality Healthcare Corporation d/b/a Fidelis Care, and Health Net, LLC v. Indivior Inc, Indivior Solutions Inc., Indivior PLC, Reckitt Benckiser Healthcare (UK) Ltd., and Aquestive Therapeutics, Inc. On September 18, 2020, Humana, Inc. (“Humana”), a health insurance payor, filed a lawsuit against the Company and Indivior in the Eastern District of Pennsylvania alleging facts similar to those at issue in the Antitrust Case and the Suboxone MDL described above, which lawsuit was assigned to the same judge that is presiding over Antitrust Case and Suboxone MDL. Humana’s Complaint alleges five causes of action against the Company, including conspiracy to violate the RICO Act, fraud under state law, unfair and deceptive trade practices under state law, insurance fraud, and unjust enrichment. On September 21, 2020, Centene Corporation (“Centene”) and other related insurance payors filed a similar lawsuit against the Company and Indivior in the Eastern District of Missouri. The counsel representing Humana is also representing Centene in this matter. On September 21, 2020, the Centene action was provisionally transferred to the Eastern District of Pennsylvania by the United States Judicial Panel on Multidistrict Litigation. On January 15, 2021, the Company filed a motion to dismiss the Centene and Humana complaints. The Court in the Eastern District of Pennsylvania dismissed all complaints against the defendants in these matters on July 22, 2021. On August 20, 2021, Centene and Humana appealed the decision to the U.S. Appeals Court for the Third Circuit (“Third Circuit”). Also, on August 20, 2021, Humana filed a complaint in state court in Kentucky, alleging the same causes of action previously filed in the federal case in the Eastern District of Pennsylvania. That state court action is stayed pending resolution of the federal appeal in the Third Circuit. The Third Circuit appeal is fully briefed and oral argument was held on March 31, 2022. The parties are awaiting a ruling from the Third Circuit on the appeal. The Company is not able to determine or predict the ultimate outcome of this proceeding or provide a reasonable estimate or range of estimates of the possible outcome or loss, if any, in this matter. California Litigation Neurelis, Inc. v. Aquestive Therapeutics, Inc. On December 5, 2019, Neurelis Inc. filed a lawsuit against us in the Superior Court of California, County of San Diego alleging the following three causes of action: (1) Unfair Competition under California Business and Professional Code § 17200 (“UCL”); (2) Defamation; and (3) Malicious Prosecution. Neurelis filed a First Amended Complaint on December 9, 2019, alleging the same three causes of action. The Company filed a Motion to Strike Neurelis’s Complaint under California’s anti-SLAPP (“strategic lawsuit against public participation”) statute on January 31, 2020, which Neurelis opposed. On August 6, 2020, the Court issued an order granting in part and denying in part the Company's anti-SLAPP motion. The Company filed a notice of appeal to the California Court of Appeal on September 1, 2020, and Neurelis filed a notice of cross-appeal on October 5, 2020. The Company filed its opening appeal brief on January 27, 2021, and briefing on the appeal ended on July 6, 2021. The Appeals Court held oral argument on the appeal on October 14, 2021, and issued its ruling on November 17, 2021. Under the ruling, the Court struck the entirety of the malicious prosecution claim and struck portions of the UCL and defamation claims. Aquestive filed a motion for attorney fees related to the anti-SLAPP motion on February 11, 2022. On April 12, 2022, Neurelis filed a Second Amended Complaint in response to the Court of Appeal's decision. The Second Amended Complaint also added a cause of action for Trade Libel. On May 3, 2022, Aquestive filed a "demurer" challenge to the sufficiency of the allegations of the Second Amended Complaint. Oral argument on Aquestive's motion for attorney fees related to the anti-SLAPP motion and on the Second Amended Complaint and demurer challenge was held on June 17, 2022. The Court entered an order granting Aquestive’s motion for attorney fees, awarding $156 and ordering Neurelis to pay the fees within 60 days of June 17, 2022. The Court denied Aquestive’s demurrer and the parties are proceeding with discovery on the claims in the Second Amended Complaint. No trial date has been set. Company is not able to determine or predict the ultimate outcome of this proceeding or provide a reasonable estimate or range of estimates of the possible outcome or loss, if any, in this matter. Neurelis IPR Litigation In the first quarter of 2019, Aquestive requested institution of three Inter Partes Reviews (“IPRs”) against Neurelis’ Orange Book method of treatment patent, US Patent No. 9,763,876 (‘876 Patent) for nasal administration of benzodiazepines (diazepam). The PTAB denied two of the requests and instituted the third request, which challenged all claims of the Neurelis ‘876 Patent. On August 6, 2020, the PTAB issued its final written decision finding all challenged claims of the ’876 Patent to be unpatentable. Neurelis appealed the decision to the U.S. Court of the Federal Circuit. On October 7, 2021, the Federal Circuit Court issued a per curium decision affirming the PTAB's final decision that the '876 Patent was unpatentable. The Federal Circuit Court issued a mandate closing the appeal period and an IPR Certificate was subsequently issued by the United States Patent and Trademark Office on January 21, 2022. No further appeals are available on this matter. Federal Securities Class Action Deanna Lewakowski v. Aquestive Therapeutics, Inc., et al.

Following the court’s appointment of a lead plaintiff, an amended complaint was filed by the plaintiffs on June 25, 2021.

Shareholder Derivative Litigation Loreen Niewenhuis v. Keith Kendall, et al. On December 15, 2021, a purported Aquestive shareholder instituted a derivative action captioned Loreen Niewenhuis v. Keith Kendall, et al. in the United States District Court for the District of New Jersey, purportedly on behalf of the Company, against certain current and former officers and directors of the Company. The case was designated as related to the pending federal securities class action Deanna Lewakowski v. Aquestive Therapeutics, Inc., referenced above, and accepted by the same judge presiding over the securities class action. The complaint in this matter alleges claims for breach of fiduciary duty and contribution. The factual allegations that form the basis of these claims are similar to the disclosure-related allegations asserted in the class action.
