Item 1A. Risk Factors

In addition to other information contained in this Annual Report on Form 10-K, the following risks should be considered in evaluating our business and future prospects and an investment in our common stock. The risks and uncertainties described below are not the only ones we face. If any of the following risks and uncertainties develops into actual events, our business, financial condition, results of operations and cash flows could be materially adversely affected. In that case, the price of our common stock could decline and you may lose all or part of your investment.

Risks Related to the Merger with Tvardi

The Merger may not be completed on the terms or timeline currently contemplated, or at all.

The consummation of the Merger is subject to numerous conditions, including (1) the effectiveness of the registration statement on Form S-4 filed in connection with the Merger, or the Registration Statement, (2) the approval

Table of Contents

by Cara’s stockholders of the required stockholder proposals set forth in the proxy statement/prospectus included in the Registration Statement, (3) the requisite approval by Tvardi’s stockholders, and (4) other customary closing conditions and there can be no assurance that the Merger will be consummated.

If the Merger is not completed for any reason, the price of Cara’s common stock may decline to the extent that the market price of Cara’s common stock reflects or previously reflected positive market assumptions that the Merger would be completed and the related benefits would be realized. In addition, Cara and Tvardi have expended and will continue to expend significant management time and resources and have incurred and will continue to incur significant expenses due to legal, advisory, printing and financial services fees related to the Merger. These expenses must be paid regardless of whether the Merger is consummated.

The exchange ratio will not be adjusted based on the market price of Cara common stock, so the consideration at the closing of the Merger may have a greater or lesser value than at the time the Merger Agreement was signed.

Each outstanding share of Tvardi common stock (after giving effect to the conversion of preferred stock and excluding shares held by stockholders who have exercised and perfected appraisal rights and excluding shares held as treasury stock by Cara or held or owned by Cara, Merger Sub or any subsidiary of Cara or Tvardi), will be converted into the right to receive a number of shares of Cara common stock based on an exchange ratio. The exchange ratio will not change based on changes in the trading price of Cara common stock. Therefore, if before the completion of the Merger, the market price of Cara common stock increases from the market price on the date of the Merger Agreement, Tvardi stockholders could then receive merger consideration with substantially higher value for their shares of Tvardi common stock than the parties had negotiated when they established the Exchange Ratio. The Merger Agreement does not include a price-based termination right. Immediately following the Merger, the pre-Merger equity holders of Cara are expected to hold approximately 15.25% of the shares of Cara common stock, the pre-Merger equity holders of Tvardi are expected to hold approximately 72.21% of the shares of Cara common stock, and the holders of the Convertible Notes are expected to hold approximately 12.54% of the shares of Cara common stock, in each case, on a fully diluted basis (subject to further adjustment as further described below), subject to certain adjustments, including based upon Cara net cash at the closing of the Merger. The calculation of Cara’s net cash at closing of the Merger includes, among other things, a credit or reduction for cash proceeds that Cara receives or pays from the Asset Disposition. The Net Cash Condition means that Cara’s net cash must be no less than $18.0 million in order for Tvardi to be required to complete the Merger.

Cara’s net cash may be less than $22.875 million at the closing of the Merger, which would result in Cara’s stockholders owning a smaller percentage of the combined company and, if Cara’s net cash is less than $18.0 million as of June 30, 2025, could even result in the termination of the Merger Agreement.

For purposes of the Merger Agreement, net cash is subject to certain reductions, including, without limitation, for payments made in connection with the sale, transfer, license, assignment or other divestiture of its intellectual property and other assets and technology in existence on the date of the Merger Agreement on or about the anticipated closing of the Merger, accounts payable, accrued expenses (except those related to the Merger), current liabilities payable in cash, unpaid expenses related to the Merger and certain other unpaid obligations. In the event the amount of Cara’s cash is smaller or such reductions are greater than anticipated, Cara stockholders could hold a significantly smaller portion of the combined company.

Failure to complete the Merger may result in Cara or Tvardi paying a termination fee to the other party and could harm the common stock price of Cara.

If the Merger is not completed, each of Cara and Tvardi is subject to the following risks:

Table of Contents

● the price of Cara’s common stock may decline and remain volatile; or

● Cara may be forced to cease its operations, dissolve and liquidate its assets.

In addition, if the Merger Agreement is terminated and the Cara Board or Tvardi Board determines to seek another business combination, there can be no assurance that either Cara or Tvardi will be able to find a partner willing to provide equivalent or more attractive consideration than the consideration to be provided by each party in the Merger or any partner at all.

If the conditions to the closing of the Merger are not met, the Merger may not occur.

Even if the required stockholder proposals set forth in the proxy statement/prospectus included in the Registration Statement are approved by the stockholders of Cara, specified conditions must be satisfied or waived to complete the Merger. Cara and Tvardi cannot assure you that all of the conditions will be satisfied or waived. If the conditions are not satisfied or waived, the Merger may not occur or will be delayed, and Cara and Tvardi each may lose some or all the intended benefits of the Merger.

The Merger may be completed even though material adverse changes may result from the announcement of the Merger, industry-wide changes and/or other causes.

In general, either Cara or Tvardi can refuse to complete the Merger if there is a Tvardi Material Adverse Effect (as defined in the Merger Agreement) or a Cara Material Adverse Effect (as defined in the Merger Agreement), as applicable, between December 17, 2024, the date of the Merger Agreement, and the closing of the Merger. However, certain types of changes do not permit either party to refuse to complete the Merger, even if such change could be said to have a material adverse effect on Cara or Tvardi, including:

● changes in financial, banking or securities markets;

Table of Contents

● the taking of any action required to be taken by the Merger Agreement.

If a material adverse change occurs with respect to either party or both parties and Cara and Tvardi still complete the Merger, the stock price of the combined company following the closing of the Merger may suffer and may reduce the value of the Merger to the stockholders of Cara, Tvardi or both.

Some executive officers and directors of Cara have interests in the Merger that are different from the respective stockholders of Cara and that may influence them to support or approve the Merger without regard to the interests of the stockholders of Cara.

Some officers and directors of Cara are parties to arrangements that provide them with interests in the Merger that are different from the stockholders of Cara, including some or all of service as an officer or director of the combined company following the closing of the Merger, severance and retention benefits, the acceleration of equity award vesting and continued indemnification.

The market price of Cara common stock following the Merger may decline as a result of the Merger.

The market price of Cara common stock may decline as a result of the Merger for a number of reasons, including if:

Cara and Tvardi equity holders will have a materially reduced ownership and voting interest in, and will exercise less influence over the management of, the combined company following the closing of the Merger as compared to their current ownership and voting interest in the respective companies.

Immediately following the Merger, the pre-Merger equity holders of Cara are expected to hold approximately 15.25% of the outstanding shares of Cara common stock, the pre-Merger equity holders of Tvardi are expected to hold approximately 72.21% of the outstanding shares of Cara common stock, and the holders of the Convertible Notes are expected to hold approximately 12.54% of the shares of Cara common stock, in each case, on a fully diluted basis (subject to further adjustment as further described below), subject to certain adjustments, including based upon Cara’s net cash at the closing of the Merger. The calculation of Cara’s net cash at the closing of the Merger includes, among other things, a credit or reduction for cash proceeds that Cara receives or pays from the Asset Disposition. The Net Cash Condition means that Cara’s net cash must be no less than $18.0 million in order for Tvardi to be required to complete the Merger.

Following the Closing, Sujal Shah will serve as Chairman and Imran Alibhai will serve as the Chief Executive Officer of Cara as the combined company. Additionally, following the closing, the combined company board of directors will consist of seven directors, and will be comprised of five members designated by Tvardi (Sujal Shah, Michael Wyzga, Wallace Hall, Shaheen Wirk and Imran Alibhai), one member to be designated by Cara prior to Closing and one vacancy, to be designated by Tvardi if prior to the closing of the Merger or by the combined company if following the consummation of the Merger.

Table of Contents

During the pendency of the Merger Agreement, Cara and Tvardi may not be able to enter into a business combination with another party at a favorable price because of restrictions in the Merger Agreement, which could adversely affect their respective businesses.

Covenants in the Merger Agreement impede the ability of Cara and Tvardi to make acquisitions, subject to specified exceptions relating to fiduciary duties, or complete other mergers, sales of assets or other business combinations pending completion of the Merger. As a result, if the Merger is not completed, the parties may be at a disadvantage to their competitors during that period. In addition, while the Merger Agreement is in effect, each party is generally prohibited from soliciting, initiating, encouraging or entering into specified extraordinary transactions, such as a merger, sale of assets or other business combination, with any third party, subject to specified exceptions, even if any such transaction could be favorable to such party’s stockholders.

Certain provisions of the Merger Agreement may discourage third parties from submitting competing proposals, including proposals that may be superior to the arrangements contemplated by the Merger Agreement.

The terms of the Merger Agreement prohibit each of Cara and Tvardi from soliciting competing proposals or cooperating with persons making unsolicited takeover proposals, except in limited circumstances for Cara when the Cara Board determines in good faith, after consultation with its outside financial advisor and outside legal counsel, that an unsolicited competing proposal constitutes, or is reasonably likely to result in, a superior competing proposal and, after consultation with its outside legal counsel, that failure to take such action is reasonably likely to be inconsistent with the fiduciary duties of the Cara Board. Even in such circumstances, while the Cara Board may change its recommendation to Cara stockholders, Cara will remain obligated to hold a stockholder vote on the Required Cara Closing Stockholder Matters and may not terminate the Merger Agreement in order to enter into an agreement with respect to a Superior Offer. In addition, if Cara or Tvardi terminate the Merger Agreement under specified circumstances, including terminating because of a decision of the Cara Board to recommend a superior competing proposal, Cara may be required to pay Tvardi a termination fee of $2.25 million and/or up to $750,000 in expense reimbursements or Tvardi may be required to pay Cara a termination fee of $2.25 million, and/or up to $750,000 in expense reimbursements. This termination fee may discourage third parties from submitting competing proposals to Cara or its stockholders and may cause the Cara Board or the Tvardi Board, as the case may be, to be less inclined to recommend a competing proposal.

Because the lack of a public market for Tvardi’s common stock makes it difficult to evaluate the fairness of the Merger, the stockholders of Tvardi may receive consideration in the Merger that is less than the fair market value of Tvardi’s common stock or Cara may pay more than the fair market value of Tvardi’s common stock.

The outstanding common stock of Tvardi is privately held and is not traded in any public market. The lack of a public market makes it extremely difficult to determine the fair market value of Tvardi’s common stock. Because the percentage of Cara equity to be issued to Tvardi stockholders was determined based on negotiations between the parties, it is possible that the value of the Cara common stock to be received by Tvardi stockholders will be less than the fair market value of Tvardi’s common stock, or Cara may pay more than the aggregate fair market value for Tvardi’s common stock.

The Piper Sandler Opinion delivered by Piper Sandler to the Cara Board prior to the entry into the Merger Agreement does not reflect changes in circumstances that may occur after the date thereof.

The Cara Board has not obtained an updated opinion either as of the date of the Annual Report on Form 10-K or as of any other date subsequent to the date of the Piper Sandler Opinion from Piper Sandler, Cara’s financial advisor. Changes in circumstances, including without limitation the operations and prospects of Cara or Tvardi, stock prices, general market and economic conditions and other factors, some or all of which may be beyond the control of Cara and Tvardi, are not reflected in the Piper Sandler Opinion. The Piper Sandler Opinion does not speak as of any date other than the date thereof.

Table of Contents

The combined company may become involved in securities litigation that could divert management’s attention and harm the combined company’s business and insurance coverage may not be sufficient to cover all costs and damages.

In the past, securities class action or stockholder derivative litigation often follows certain significant business transactions, such as the sale of a business division or announcement of a merger. The combined company may become involved in this type of litigation in the future in connection with the Merger and the other Contemplated Transactions. As of the date of this Annual Report on Form 10-K, Cara has received five demand letters from purported stockholders relating to the Merger and the other Contemplated Transactions and the disclosures contained in the proxy statement/prospectus related to the Contemplated Transactions. Responding to these demands and litigation often is expensive and diverts management’s attention and resources, which could adversely affect the combined company’s business.

Cara or Tvardi may waive one or more of the conditions to the Merger without recirculation of the proxy statement/prospectus or resoliciting stockholder approval.

Conditions to Cara’s or Tvardi’s obligations to complete the Merger may be waived, in whole or in part, to the extent permitted by law, in certain circumstances unilaterally or by agreement of Cara and Tvardi. In the event of a waiver of a condition, the Cara Board will evaluate the materiality of any such waiver to determine whether amendment of the proxy statement/prospectus and resolicitation of stockholder approval is necessary.

In the event that the Cara Board, in its own reasonable discretion, determines any such waiver is not significant enough to require recirculation of this proxy statement/prospectus and re-solicitation of its stockholders, it will have the discretion to complete the Merger without seeking further stockholder approval, which decision may have a material adverse effect on the Cara stockholders. For example, if Cara and Tvardi agree to waive the requirement that the shares of Cara common stock to be issued in the Merger have been approved for listing (subject to official notice of issuance) on Nasdaq as of the closing of the Merger, and their respective boards of directors elect to proceed with the closing of the Merger, Nasdaq may notify the combined company of its determination to delist the company’s securities based upon the failure to satisfy the initial inclusion criteria in the Nasdaq application. The combined company may appeal the determination to a hearings panel but such appeal will not stay the suspension and delisting action and Nasdaq may notify the combined company that its common stock will be immediately suspended from trading and delisted.

In addition, in order to meet the initial listing requirements of Nasdaq, Cara may release Tvardi stockholders from their Lock-Up Agreements and waive the requirement that such Lock-Up Agreements be in full force and effect immediately following the Effective Time. Such release would increase the number of shares that may be sold in the public market immediately after the Merger and any such sales could cause the combined company’s stock price to decline.

Transfers of the combined company’s securities utilizing Rule 144 of the Securities Act may be limited.

A significant portion of the combined company’s securities will be restricted from immediate resale. Holders should be aware that transfers of Cara’s securities pursuant to Rule 144 under the Securities Act (Rule 144) may be limited as Rule 144 is not available, subject to certain exceptions, for the resale of securities initially issued by shell companies (other than business combination related shell companies) or issuers that have previously been a shell company. Cara’s winddown of its historical operations, the suspension of development activities and the proposed Merger will make Cara subject to the SEC requirements applicable to reporting shell company business combinations. Cara anticipates that following the consummation of the proposed transaction, the combined company will no longer be a shell company. As a result, Cara anticipates that holders will not be able to sell their restricted combined company securities pursuant to Rule 144 without registration until one year after the combined company files the Current Report on Form 8-K following the closing that includes the required Form 10 type information that reflects that the combined company is no longer a shell company.

Table of Contents

Cara’s winddown of its historical operations, the sale of assets, the suspension of development activities and the proposed Merger, resulting in the conversion of Tvardi into a public company, will make Cara subject to the SEC requirements applicable to reporting shell company business combinations. As a result, the combined company will be subject to more stringent reporting requirements, offering limitations and resale restrictions.

According to SEC guidance, the requirements applicable to reporting shell company business combinations apply to any company that sells or otherwise disposes of its historical assets or operations in connection with or as part of a plan to combine with a non-shell private company in order to convert the private company into a public one. Cara has suspended its development activities and, as such, Cara’s plan to merge with Tvardi, resulting in the conversion of Tvardi into a public company, will be subject to the SEC requirements applicable to reporting shell company business combinations, which are as follows:

The foregoing SEC requirements will increase the combined company’s time and cost of raising capital, offering stock under equity plans, and complying with securities laws. Furthermore, such requirements will add burdensome restrictions on the resale of the combined company common stock by affiliates of Tvardi and any holders of “restricted” or “control” securities of the combined company.

Nasdaq may delist the combined company’s securities from trading on its exchange, which could limit investors’ ability to make transactions in its securities and subject the combined company to additional trading restrictions.

Currently, Cara’s common stock is publicly traded on The Nasdaq Capital Market. In connection with the proposed Merger, Tvardi will file an initial listing application with Nasdaq pursuant to Nasdaq’s “reverse merger” rules. The combined company will be required to meet the initial listing requirements for its securities to be listed on Nasdaq.

Table of Contents

If Cara and Tvardi fail to meet the Nasdaq listing requirements and their respective boards choose to close the merger without Nasdaq’s approval, then Nasdaq may notify the combined company of its determination to delist the company’s securities based upon the failure to satisfy the criteria in the Nasdaq application. For more information, refer to the section titled “Risk Factors Related to the Merger—Cara or Tvardi may waive one or more of the conditions to the Merger without recirculation of the proxy statement/prospectus or resoliciting stockholder approval”.

We cannot assure you that the combined company will be able to meet those initial listing requirements. Even if the combined company’s securities are so listed, the combined company may be unable to maintain the listing of its securities in the future. In order to continue listing its securities on Nasdaq following the proposed Merger, the combined company will be required to maintain certain financial, distribution and stock price levels. If Nasdaq delists the combined company’s securities from trading on its exchange at closing of the Merger (or thereafter) and the combined company is not able to list its securities on another national securities exchange or regain compliance with Nasdaq, the combined company’s securities could be quoted on an over-the-counter market. If this were to occur, the combined company could face significant material adverse consequences, including:

● a limited availability of market quotations for its securities;

● reduced liquidity for its securities;

● a limited amount of news and analyst coverage; and

The National Securities Markets Improvement Act of 1996, which is a federal statute, prevents or preempts states from regulating the sale of certain securities, which are referred to as “covered securities.” Since Cara’s common stock is listed on Nasdaq, they are covered securities. Although states are preempted from regulating the sale of covered securities, the federal statute does allow states to investigate companies if there is a suspicion of fraud, and, if there is a finding of fraudulent activity, then states can regulate or bar the sale of covered securities in a particular case. If Cara was no longer listed on Nasdaq, its securities would not be covered securities and it would be subject to regulation in each state in which it offers its securities, including in connection with the Merger.

The financial projections considered by the Cara Board in evaluating the Merger and used by Piper Sandler at the direction of Cara in rendering its Opinion and performing its related financial analyses, reflect numerous variables, estimates and assumptions and are inherently uncertain.

In connection with the Cara Board’s evaluation of the Merger, Cara’s management prepared certain short-term unaudited prospective internal financial projections with respect to Cara that were provided to the Cara Board in connection with its evaluation of the Merger and to Piper Sandler in connection with its financial analysis and Opinion. The financial projections reflect numerous variables, estimates, forecasts and assumptions and these variables, estimates, forecasts and assumptions may prove to be wrong.

Risks Related to Cara’s Strategic Alternative Process and Potential Strategic Transaction

Failure to complete, or delays in completing, the Merger with Tvardi could materially and adversely affect Cara’s results of operations, business, financial results and/or stock price.

In June 2024, Cara announced that it was undertaking a comprehensive exploration of strategic alternatives focused on maximizing stockholder value. After a comprehensive review of strategic alternatives, including identifying and reviewing potential candidates for the merger, on December 17, 2024, Cara entered into the Merger Agreement. The closing is subject to approval by the Cara stockholders and Tvardi stockholders as well as other customary closing

Table of Contents

conditions, including the effectiveness of a registration statement filed with the SEC in connection with the transaction. If the Merger is completed, the business of Tvardi will continue as the business of the combined company. Any failure to satisfy a required condition to closing may prevent, delay or otherwise materially and adversely affect the completion of the transaction, which could materially and adversely affect Cara’s results of operations, business, financial results and/or stock price. Cara cannot predict with certainty whether or when any of the required closing conditions will be satisfied or if another uncertainty may arise and cannot assure you that the Merger will be successfully consummated or that Cara will be able to successfully consummate the proposed merger as currently contemplated under the Merger Agreement or at all.

Cara’s efforts to complete the Merger could cause substantial disruptions in, and create uncertainty surrounding, Cara’s business, which may materially adversely affect Cara’s results of operations and Cara’s business. Uncertainty as to whether the Merger will be completed may affect Cara’s ability to retain and motivate existing employees. Employee retention may be particularly challenging while the transaction is pending because employees may experience uncertainty about their roles during and following the transaction. A substantial amount of Cara management’s and employees’ attention is being directed toward the completion of the transaction and thus is being diverted from Cara’s day-to-day operations. Uncertainty as to Cara’s future could adversely affect Cara’s business and Cara’s relationship with collaborators, suppliers, vendors, regulators and other business partners. For example, vendors, collaborators and other counterparties may defer decisions about working with Cara or seek to change existing business relationships with Cara. Changes to, or termination of, existing business relationships could adversely affect Cara’s results of operations and financial condition, as well as the market price of Cara’s common stock. The adverse effects of the pendency of the transaction could be exacerbated by any delays in completion of the transaction or termination of the Merger Agreement.

Risks related to the failure to consummate, or delay in consummating, the Merger with Tvardi include, but are not limited to, the following:

Table of Contents

The occurrence of any of these events individually or in combination could materially and adversely affect Cara’s results of operations, business, and Cara’s stock price.

Cara cannot be sure if or when the Merger will be completed.

The consummation of the Merger is subject to the satisfaction or waiver of various conditions, including the authorization of the Merger by Cara stockholders and Tvardi stockholders. Cara cannot guarantee that the closing conditions set forth in the Merger Agreement will be satisfied. If Cara is unable to satisfy certain closing conditions or if other mutual closing conditions are not satisfied, Tvardi will not be obligated to complete the Merger.

Under certain circumstances, Cara would be required to pay Tvardi a termination fee of $2.25 million. Additionally, if the Merger Agreement is terminated by Cara or Tvardi due to Cara stockholders voting on and failing to approve certain proposals, Cara will be required to reimburse Tvardi for Merger-related expenses up to $750,000. The expense reimbursement, to the extent paid, will be credited against any termination fee payable by Cara in the transaction. Even if a termination fee is not payable in connection with a termination of the Merger Agreement, Cara will have incurred significant fees and expenses, which must be paid whether or not the Merger is completed. If the Merger is not completed, the Cara Board, in discharging its fiduciary obligations to Cara stockholders, would evaluate other strategic alternatives or financing options that may be available, which alternatives may not be as favorable to Cara stockholders as the Merger, including a liquidation and dissolution. Any future sale or Merger, financing or other transaction, including a liquidation or dissolution, may be subject to further stockholder approval. Cara may also be unable to find, evaluate or complete other strategic alternatives, which may have a materially adverse effect on Cara’s business. Until the Merger is completed, the Merger Agreement restricts Tvardi and Cara from taking specified actions without the consent of the other party, and requires Cara to operate in the ordinary course of business consistent with past practice. These restrictions may prevent Tvardi and Cara from making appropriate changes to Cara respective businesses or pursuing attractive business opportunities that may arise prior to the completion of the Merger. Further, if Cara’s net cash at closing is lower than anticipated, either because expenses exceed current estimates or due to delays prior to closing, then the pre-Merger Cara stockholders will own less of the combined company pursuant to the exchange ratio adjustment set forth in the Merger Agreement. Any delay in completing the Merger may materially and adversely affect the timing and benefits that are expected to be achieved from the Merger.

If Cara does not successfully consummate the Merger or another strategic transaction, Cara’s Board may decide to pursue a dissolution and liquidation of Cara. In such an event, the amount of cash available for distribution to Cara’s stockholders will depend significantly on the timing of such liquidation as well as the amount of cash that will need to be reserved for commitments and contingent liabilities, as to which Cara can give you no assurance.

There can be no assurance that the Merger will be completed. If the Merger is not completed, the Cara Board may decide to pursue a dissolution and liquidation of Cara. In such an event, the amount of cash available for distribution to Cara stockholders will depend heavily on the timing of such decision and, ultimately, such liquidation, since the amount of cash available for distribution continues to decrease as Cara continues to fund its operations while pursuing the Merger. In addition, if Cara’s Board were to approve and recommend, and Cara stockholders were to approve, a dissolution and liquidation, Cara would be required under Delaware corporate law to pay Cara’s outstanding obligations, as well as to make reasonable provision for contingent and unknown obligations, prior to making any distributions in liquidation to stockholders. Cara’s commitments and contingent liabilities may include obligations under Cara’s employment and related agreements with certain employees that provide for severance and other payments following a termination of employment occurring for various reasons, including a change in control of the company, litigation against Cara, and other various claims and legal actions arising in the ordinary course of business, and other unexpected and/or contingent liabilities, As a result of this requirement, a portion of Cara’s assets would need to be reserved pending the resolution of such obligations and the timing of any such resolution is uncertain.

In addition, Cara may be subject to litigation or other claims related to a dissolution and liquidation. If a dissolution and liquidation were pursued, Cara’s Board, in consultation with its advisors, would need to evaluate these matters and make a determination about a reasonable amount to reserve. Accordingly, holders of Cara’s common stock could lose all or a significant portion of their investment in the event of a liquidation, dissolution or winding up of the

Table of Contents

company. A liquidation would be a lengthy and uncertain process with no assurance of any value ever being returned to Cara stockholders.

The value to stockholders in the event of a strategic transaction or dissolution may depend on the extent to which Cara will be able to successfully satisfy its existing contractual obligations to third parties and regulatory commitments on favorable terms, which may include the outcome of Cara’s negotiations to reduce or terminate such commitments.

Cara is currently subject to certain contractual and regulatory obligations and commitments. In connection with its comprehensive exploration of strategic alternatives, Cara may seek to negotiate with third parties in order to reduce or eliminate such obligations and commitments. For example, on December 17, 2024, Cara and its subsidiary, Cara Royalty Sub, LLC (Cara Royalty Sub, and together with Cara, each, a Seller and together, the Sellers), entered into the APA with CSL Vifor, pursuant to which, at the consummation of the transaction, Sellers will sell to CSL Vifor and CSL Vifor will acquire from Sellers certain assets and rights for the development, manufacture and commercialization of difelikefalin as well as certain associated liabilities, or the Asset Disposition. Pursuant to the APA, in connection with the consummation of the Asset Disposition, CSL Vifor and HCR have entered into a letter agreement with Cara providing that CSL Vifor and HCR will, subject to the satisfaction of conditions to closing under the APA, enter into an amended and restated purchase agreement to amend and replace the Original HCR Agreement, by and among Cara Royalty Sub, HCRX Investments HoldCo, L.P. and HCR. Upon entering into the amended and restated purchase agreement, effective as of the closing of the Asset Disposition: (i) CSL Vifor will be obligated to make certain payments to HCR from and after the date thereof relating to certain revenue and/or royalties from difelikefalin, (ii) each of the Contribution Agreement, the License Agreement and the Pledge Agreement (each as defined in the Original HCR Agreement) shall be terminated, and (iii) Sellers shall have no further payment or other obligations to HCR under the Original HCR Agreement. Additionally, pursuant to the APA, at the consummation of the Asset Disposition, Cara has agreed to pay CSL Vifor $3.0 million to compensate CSL Vifor for the estimated incremental future expenses to be incurred by CSL Vifor as a result of the transfer of the assets to be acquired and the liabilities to be assumed by it in connection with the Asset Disposition.

The Asset Disposition is subject to certain conditions to closing, including either (i) the consummation of the Merger concurrently with the Asset Disposition or (ii) the receipt of the requisite stockholder approval needed to approve the Asset Disposition in the event that the Merger is terminated. The APA provides for certain termination rights of Sellers and CSL Vifor, including the right of either CSL Vifor or Cara to terminate the APA if (a) there is a permanent and nonappealable prohibition on the consummation of the Asset Disposition, (b) the Asset Disposition has not occurred by June 30, 2025 (which date shall be automatically extended in one-month increments until October 30, 2025 in certain instances if the Merger is not closed by June 30, 2025) or (c) if a meeting of Cara’s stockholders has been held for the stockholders to consider and vote upon the APA and the Asset Disposition and the stockholders have not voted in favor of adopting the APA and approving the Asset Disposition at such stockholder meeting. Either party may also terminate the APA if the other party breaches its obligations under the APA in certain instances and subject to customary cure protections. The APA contains representations, warranties, and covenants of the parties, including, among others, a covenant that requires (i) Sellers to operate their business in the ordinary course during the period between the execution of the APA and consummation of the Asset Disposition and to not engage in certain kinds of activities or transactions during such period (subject to either prior consent of CSL Vifor or customary limited exceptions), (ii) the parties to use their reasonable best efforts to complete certain transition steps in connection with the consummation of the Asset Disposition, and (iii) Sellers to use their commercially reasonable efforts to obtain any needed consents and provide any needed notices in connection with the Asset Disposition. Cara currently has license agreements with Maruishi Pharmaceutical Co., Ltd. (Maruishi), and Chong Kun Dang Pharmaceutical Corporation (CKDP), for the intravenous and oral formulations of difelikefalin, and manufacturing agreements with Polypeptide Laboratories S.A. (PPL) and Patheon UK Limited (Patheon) for the difelikefalin injection. Cara expects to assign these agreements with each of Maruishi, CKDP, PPL and Patheon to CSL Vifor in connection with the Merger and Asset Disposition.

Cara’s ability to successfully negotiate such obligations or commitments on favorable terms, or at all, or Cara’s ability to satisfy any such obligations may impact Cara’s ability to pursue or implement a strategic transaction on terms favorable to Cara, the resulting value to stockholders in a strategic transaction or the cash available for distribution to

Table of Contents

Cara’s stockholders in the event of its dissolution. Cara may also incur substantial costs in connection with or as a result of such negotiations or termination of any of its commitments. There can be no assurance that Cara will be successful in negotiating to reduce or eliminate any of its existing contractual or regulatory obligations and commitments, or that Cara will be able to satisfy any such obligations on a timetable that will allow Cara to maximize potential value to its stockholders.

Lawsuits may be filed against Cara and the members of the Cara Board arising out of the Merger, which may delay or prevent the proposed merger.

Putative stockholder complaints, including stockholder class action complaints, and other complaints may be filed against Cara, the Cara Board, Tvardi, the Tvardi Board and others in connection with the transactions contemplated by the Merger Agreement. As of the date of this Annual Report on Form 10-K, Cara has received five demand letters from purported stockholders relating to the proposed Merger and the Contemplated Transactions and the disclosures contained in the proxy statement/prospectus related to the Contemplated Transactions. The outcome of litigation is uncertain, and Cara may not be successful in defending against any such future claims. Lawsuits that may be filed against Cara, the Cara Board, Tvardi or the Tvardi Board could delay or prevent the merger, divert the attention of Cara’s management and employees from Cara’s day-to-day business and otherwise adversely affect Cara’s financial condition. Litigation may also impact Cara’s ability to consummate a potential strategic transaction or the ultimate value its stockholders receive in any such transaction.

Cara is substantially dependent on its remaining employees to facilitate the consummation of the Merger.

Cara’s ability to consummate a strategic transaction depends upon its ability to retain its employees required to consummate such a transaction, the loss of whose services may adversely impact the ability to consummate such transaction. In January 2024 and June 2024, Cara implemented reductions in force that significantly reduced its workforce in order to conserve its capital resources. As of March 6, 2025, Cara had only ten full-time employees. Cara’s ability to successfully complete the merger depends in large part on Cara’s ability to retain certain remaining personnel. Despite Cara’s efforts to retain these employees, one or more may terminate their employment with Cara on short notice. Cara’s cash conservation activities may yield other unintended consequences, such as attrition beyond its planned reduction in workforce and reduced employee morale, which may cause remaining employees to seek alternative employment. The loss of the services of certain employees could potentially harm Cara’s ability to consummate the merger, to run Cara’s day-to-day business operations and to fulfill Cara’s reporting obligations as a public company.

Cara may not be successful in completing the Merger, and any strategic transactions that it may consummate in the future could have negative consequences.

There can be no assurance that Cara will be able to successfully consummate the Merger or that the Merger will be completed on attractive terms, within the anticipated timing, or at all. The process of continuing to evaluate these strategic options may be very costly, time-consuming and complex and Cara has incurred, and may in the future incur, significant costs related to this continued evaluation, such as legal and accounting fees and expenses and other related charges. Cara may also incur additional unanticipated expenses in connection with this process. A considerable portion of these costs will be incurred regardless of whether any such course of action is implemented or transaction is completed. Any such expenses will decrease the remaining cash available for use in its business.

In addition, any strategic business combination or other transactions that Cara may consummate in the future could have a variety of negative consequences and Cara may implement a course of action or consummate a transaction that yields unexpected results that adversely affects its business and decreases the remaining cash available for use in its business or the execution of its strategic plan. There can be no assurances that any particular course of action, business arrangement or transaction, or series of transactions, will be pursued, successfully consummated, lead to increased stockholder value or achieve the anticipated results. Any potential transaction would be dependent on a number of factors that may be beyond its control, including, among other things, market conditions, industry trends, the interest of third parties in a potential transaction with Cara, obtaining stockholder approval and the availability of financing to third parties in a potential transaction with Cara on reasonable terms. Any failure of such a potential transaction to achieve the

Table of Contents

anticipated results could significantly impair Cara’s ability to enter into any future strategic transactions and may significantly diminish or delay any future distributions to its stockholders.

If Cara is not successful in setting forth a new strategic path for Cara, or if its plans are not executed in a timely fashion, this may cause reputational harm with Cara’s stockholders and the value of its securities may be adversely impacted. In addition, speculation regarding any developments related to the review of strategic alternatives and perceived uncertainties related to the future of Cara could cause its stock price to fluctuate significantly.

If Cara is successful in completing the Merger, it may be exposed to other operational and financial risks.

Although there can be no assurance that the Merger will be completed, the negotiation and consummation of the Merger has required and will continue to require significant time on the part of its management, and the diversion of management’s attention may disrupt its business. The negotiation and consummation of the Merger may also require more time or greater cash resources than Cara anticipates and exposes Cara to other operational and financial risks, including:

● increased near-term and long-term expenditures;

● exposure to unknown liabilities;

● higher than expected acquisition or integration costs;

● increased amortization expenses;

● inability to retain key employees of Cara or any acquired business; and

● possibility of future litigation.

Any of the foregoing risks could have a material adverse effect on Cara’s business, financial condition and prospects.

Cara’s corporate restructuring and the associated reduction in workforce may not result in anticipated savings, could result in total costs and expenses that are greater than expected and could disrupt its business.

In January 2024 and June 2024, Cara implemented reductions in force that significantly reduced its workforce in order to conserve its capital resources. Cara may not realize, in full or in part, the anticipated benefits, savings and improvements in its cost structure from its restructuring efforts due to unforeseen difficulties, delays or unexpected costs. If Cara is unable to realize the expected operational efficiencies and cost savings from the restructuring, its operating results and financial condition will be adversely affected. Furthermore, its restructuring plan may be disruptive to its operations. For example, Cara’s headcount reductions could yield unanticipated consequences, such as increased difficulties in implementing its business strategy, including retention of its remaining employees. Employee litigation related to the headcount reduction could be costly and prevent management from fully concentrating on the business. Any future growth of Cara’s business would impose significant added responsibilities on members of management,

Table of Contents

including the need to identify, recruit, maintain and integrate additional employees. Due to its limited resources, Cara may not be able to effectively manage its operations or recruit and retain qualified personnel, which may result in weaknesses in its infrastructure and operations, risks that Cara may not be able to comply with legal and regulatory requirements, loss of employees and reduced productivity among remaining employees.

The impact and results of Cara’s ongoing strategic process are uncertain and may not be successful.

The Cara Board remains dedicated to diligent deliberations and the making of informed decisions that the directors believe are in the best interests of the company and its stockholders. There can be no assurance, however, that the company’s current strategic direction, or the Cara’s Board’s evaluation of strategic alternatives, will result in any initiatives, agreements, transactions or plans that will further enhance stockholder value. In addition, given the substantial restructuring of Cara’s operations over the past several years, it may be difficult to evaluate its current business and future prospects on the basis of historical operating performance.

Risks Related to Cara’s Financial Condition and Capital Requirements

Cara has incurred significant losses from Cara’s inception, and Cara anticipates that it may incur losses in the foreseeable future.

Cara is a biopharmaceutical company. Until recently, Cara had focused its efforts primarily on developing KORSUVA injection, Kapruvia and oral difelikefalin for a number of indications with the goal of achieving regulatory approval and, more recently, commercializing KORSUVA injection and Kapruvia. However, the commercial launches of KORSUVA injection and Kapruvia did not achieve meaningful success and, in January 2024, Cara made the strategic decision to focus its efforts on developing oral difelikefalin for the treatment of pruritus associated with NP. In June 2024, Cara discontinued the clinical program in NP following the outcome from the dose-finding Part A of the KOURAGE-1 study evaluating the efficacy and safety of oral difelikefalin for moderate-to-severe pruritus in adult patients with NP in which oral difelikefalin did not demonstrate a meaningful clinical benefit at any dose compared to placebo. At that time, Cara announced it would conduct a comprehensive exploration of strategic alternatives focused on maximizing stockholder value and in December 2024 Cara announced its proposed merger with Tvardi. Since inception, Cara has incurred significant operating and net losses. Cara incurred net losses of $70.9 million, $118.5 million and $85.5 million for the years ended December 31, 2024, 2023 and 2022, respectively. As of December 31, 2024, Cara had an accumulated deficit of $755.6 million. In connection with the termination of all ongoing clinical programs noted above, Cara’s research and development expenses have decreased. Cara expects to continue to incur costs and expenditures in connection with the merger process. There can be no assurance that the proposed merger with Tvardi, or any other course of action, business arrangement or transaction, or series of transactions, will be pursued, successfully consummated or lead to increased stockholder value. Further, if Cara does not obtain additional funding and/or if a strategic transaction is not completed and Cara is unable to continue as a going concern, Cara may have to liquidate its assets and the values Cara receives for the assets in liquidation or dissolution could be significantly lower than the values reflected in Cara’s consolidated financial statements.

Should Cara resume development activities in the future, Cara expects that research and development costs would increase significantly and Cara would continue to incur significant expenses and operating and net losses, as Cara develops and seeks regulatory approval for such product candidates.

Cara’s financial results may fluctuate significantly from year to year, depending on whether Cara resumes development of its product candidate or any future product candidates, the timing of any clinical trials, the receipt of payments under any future agreements Cara may enter into, and its expenditures on other R&D activities as well as any payments owed under the License Agreement with Enteris and any future similar agreements.

Should Cara resume development activities in the future, Cara expects it would continue to incur significant losses for the foreseeable future as it:

● continues the development of any product candidate;

Table of Contents

● maintains, expands and protects its global intellectual property portfolio;

● hires additional clinical, quality control and scientific personnel; and

Revenues from KORSUVA injection will not be sufficient to enable Cara to reach profitability. To become and remain profitable from product sales, Cara must succeed in developing and eventually commercializing one or more products that generate significant revenue. In order to commercialize any product candidate, Cara will need to be successful in a range of challenging activities, including, should Cara resume the development of its product candidate or any future product candidate, successful registration of oral difelikefalin, discovering, developing, licensing or acquiring additional product candidates and completing preclinical testing and clinical trials for those product candidates, potentially entering into collaboration and license agreements, obtaining regulatory approval for product candidates and manufacturing, marketing and selling approved products and product candidates for which Cara may obtain regulatory approval. Cara may never succeed in these activities and, even if Cara does, may never achieve profitability.

Because of the numerous risks and uncertainties associated with pharmaceutical product development, Cara is unable to accurately predict the timing or amount of increased expenses or when, or if, should Cara resume development activities in the future, Cara will be able to achieve profitability. If Cara is required by the FDA or foreign regulatory authorities, to perform studies in addition to those expected, or if there are any delays in completing Cara’s clinical trials or the development of Cara’s product candidate, Cara’s expenses could increase.

Even if Cara does achieve profitability from product sales, Cara may not be able to sustain or increase profitability on a quarterly or annual basis. Cara’s failure to become and remain profitable would depress the value of the company and could impair Cara’s ability to raise capital, expand its business, should Cara resume the development of its product candidate or any future product candidate, maintain its R&D efforts and diversify its product offerings, or even continue its operations. A decline in the value of the company could also cause you to lose all or part of your investment.

If Cara decides to resume development of Cara’s product candidate or any future product candidate, Cara will need additional funding and may be unable to raise capital when needed, which would force Cara to delay, reduce or eliminate its product development programs.

Conducting clinical trials, pursuing regulatory approvals, establishing outsourced manufacturing relationships, and successfully manufacturing and commercializing products and product candidates is expensive. If Cara resumes development of its product candidate or any future product candidate, Cara will need to raise additional capital to resume the development of oral difelikefalin and potentially in-license or acquire other product candidates.

In January 2024, Cara announced a prioritization of its pipeline to focus its resources on its late-stage clinical program evaluating oral difelikefalin in chronic pruritus associated with NP and terminate Cara’s Phase 3 clinical program evaluating oral difelikefalin in pruritus associated with advanced chronic kidney disease, including its KICK 1 and KICK 2 Phase 3 clinical trials. As part of this strategic update, in the first quarter of 2024, Cara reduced its global workforce by approximately 50%. In June 2024, Cara discontinued the clinical program in NP following the outcome from the dose-finding Part A of the KOURAGE-1 study evaluating the efficacy and safety of oral difelikefalin for moderate-to-severe pruritus in adult patients with NP in which oral difelikefalin did not demonstrate a meaningful clinical benefit at any dose compared to placebo. Following the discontinuation of the clinical program in NP, Cara announced that it was undertaking a comprehensive exploration of strategic alternatives focused on maximizing stockholder value. In connection with its streamlined operating plan, Cara further reduced its headcount by approximately 70%. Cara has incurred, and expects to continue to incur, significant costs in connection with this process.

Table of Contents

After taking into account the discontinuation of Cara’s clinical development programs, reduction in workforce and comprehensive exploration of strategic alternatives, Cara expects that its current unrestricted cash and cash equivalents and available-for-sale marketable securities will be sufficient to fund its currently anticipated operating plan for at least the next 12 months. In connection with the termination of all ongoing clinical programs, Cara’s research and development expenses have decreased. Should Cara resume development activities in the future, Cara expects that research and development costs would increase significantly. It is possible that the assumptions upon which Cara has based this estimate may prove to be wrong, and Cara could use its capital resources sooner than it presently expects.

Cara’s future funding requirements will depend on many factors, including, but not limited to:

● the effect of competing technological and market developments; and

Future capital requirements will also depend on the extent to which Cara acquires or invests in additional complementary businesses, products and technologies. Until Cara can generate a sufficient amount of product revenue, if ever, Cara may seek to finance future cash needs through public or private equity offerings, debt financings, milestone and royalty payments from corporate collaboration and licensing arrangements, as well as through interest income earned on cash and investment balances. Cara cannot be certain that additional funding will be available on acceptable terms, or at all, and Cara’s ability to raise additional capital may be adversely impacted by potential worsening global economic conditions, including fluctuations in inflation and interest rates, the continuing disruptions to and volatility in the credit and financial markets in the United States and worldwide, including resulting from the ongoing conflicts between Russia and the Ukraine, conflicts in the Middle East, and increasing tensions between China and Taiwan.

Risks Related to Cara’s Business and the Development and Commercialization of Its Product and Potential Product Candidates

Should Cara resume development of its product candidate or future product candidates, if Cara is unable to successfully complete clinical development, obtain regulatory approvals and commercialize its product candidate or future product candidates, or experience significant delays in doing so, its business will be materially harmed.

Should Cara resume development of its product candidate or any future product candidates, its business will depend on the successful development, regulatory approval, and commercialization of such product candidates. In January 2024, Cara announced a prioritization of its pipeline to focus its resources on its late-stage clinical program evaluating oral difelikefalin in chronic pruritus associated with NP and terminate its Phase 3 clinical program evaluating oral difelikefalin in pruritus associated with advanced chronic kidney disease, including the KICK 1 and KICK 2 Phase 3

clinical trials. In June 2024, Cara discontinued the clinical program in NP following the outcome from the dose-finding Part A of the KOURAGE-1 study evaluating the efficacy and safety of oral difelikefalin for moderate-to-severe pruritus in adult patients with NP in which oral difelikefalin did not demonstrate a meaningful clinical benefit at any dose compared to placebo. Should Cara resume development activities in the future, Cara cannot be certain that any such product candidates will be successful in clinical trials or receive regulatory approval. Regulatory authorities may interpret Cara’s data differently than Cara does. Cara is not permitted to market or promote any of its product candidates before it receives regulatory approval from the FDA or comparable foreign regulatory authorities, and, should Cara resume development activities in the future it may never receive such regulatory approval for oral difelikefalin or any future product candidates.

Should Cara resume development of its product candidate or any future product candidates, the success of such product candidates will depend on many factors, including but not limited to:

● receipt of additional regulatory approvals;

● competition with other products;

● continued acceptable safety profile following regulatory approval; and

If Cara does not achieve and maintain one or more of these factors in a timely manner or at all, Cara could experience significant delays in its ability to, or be unable to obtain regulatory approvals for, and/or to successfully commercialize any products or product candidates, should Cara resume development of its product candidate or any

Table of Contents

future product candidate, which would materially harm Cara’s business and Cara may not be able to generate sufficient revenues and cash flows to continue its operations.

Clinical and preclinical drug development involves a lengthy and expensive process with uncertain timelines and outcomes, and the results of preclinical studies and early clinical trials are not necessarily predictive of future results. Should Cara resume development of its product candidate or any potential future product candidate, such product candidate may not achieve favorable results in clinical trials or preclinical studies or receive regulatory approval on a timely basis, if at all.

Drug development is expensive and can take many years to complete, and its outcome is inherently uncertain. Should Cara resume development of its product candidate or any future product candidate, Cara cannot guarantee that any clinical trials or preclinical studies will be conducted as planned, including whether Cara is able to meet expected timeframes for data readouts, or complete on schedule, if at all, and failure can occur at any time during the trial or study process, including due to factors that are beyond Cara’s control.

Should Cara resume development activities in the future, the results from preclinical studies or clinical trials of oral difelikefalin, any potential future product candidates, or a competitor’s product candidate in the same class may not predict the results of later clinical trials, and interim, topline or preliminary results of a clinical trial are not necessarily indicative of final results. Oral difelikefalin or any future product candidate in later stages of clinical trials may fail to show the desired characteristics despite having progressed through preclinical studies and initial clinical trials. It is not uncommon to observe results in clinical trials that are unexpected based on preclinical studies and early clinical trials, and many product candidates fail in clinical trials despite very promising early results. For example, in December 2023, Cara announced the outcome from the dose-finding Part A of the KIND 1 study evaluating the efficacy and safety of oral difelikefalin in moderate-to-severe pruritus associated with atopic dermatitis as an adjunct to topical corticosteroids. In the study, oral difelikefalin did not demonstrate a meaningful clinical benefit, which resulted in Cara’s decision to discontinue the clinical program in atopic dermatitis. Further, in June 2024, Cara discontinued the clinical program in NP following the outcome from the dose-finding Part A of the KOURAGE-1 study evaluating the efficacy and safety of oral difelikefalin for moderate-to-severe pruritus in adult patients with NP in which oral difelikefalin did not demonstrate a meaningful clinical benefit at any dose compared to placebo.

Moreover, preclinical and clinical data may be susceptible to varying interpretations and analyses. A number of companies in the biopharmaceutical and biotechnology industries have suffered significant setbacks in clinical development even after achieving promising results in earlier studies. Such setbacks have occurred and may occur for many reasons, including, but not limited to: clinical sites and investigators may deviate from clinical trial protocols, whether due to lack of training or otherwise, and Cara may fail to detect any such deviations in a timely manner; patients may fail to adhere to any required clinical trial procedures, including any requirements for post-treatment follow-up; product candidates may fail to demonstrate safety, potency (or efficacy) in certain patient subpopulations, which has not been observed in earlier trials due to limited sample size, lack of analysis or otherwise; or, should Cara resume development of its product candidate or any future product candidate, its clinical trials may not adequately represent the patient populations Cara intends to treat, whether due to limitations in Cara’s trial designs or otherwise, such as where one patient subgroup is overrepresented in the clinical trial. There can be no assurance that Cara will not suffer similar setbacks despite the data Cara may observe in earlier studies. Based upon negative or inconclusive results, Cara or any current or any future collaborator may decide, or regulators may require, Cara to conduct additional preclinical studies or clinical trials, which would cause Cara to incur additional operating expenses and delays and may not be sufficient to support regulatory approval on a timely basis or at all.

As a result, Cara cannot be certain that, should Cara resume development of its product candidate or any future product candidate, any clinical trials or preclinical studies will be successful. Any safety concerns observed in any clinical trials, should Cara resume development of its product candidate or any future product candidate, could limit the prospects for regulatory approval of such product candidate, which could have a material adverse effect on Cara’s business, financial condition, results of operations and prospects.

Table of Contents

Should Cara resume development of its product candidate or any future product candidate, if Cara experiences delays or difficulties in the enrollment of patients in clinical trials, Cara’s receipt of necessary regulatory approvals could be delayed or prevented.

Should Cara resume development of Cara’s product candidate or any future product candidate, Cara may not be able to initiate or continue conducting clinical trials for any such product candidate if Cara is unable to locate and enroll a sufficient number of eligible patients to participate in these trials as required by the FDA or similar regulatory authorities outside the United States. Cara’s competitors may have ongoing clinical trials for product candidates that treat the same indications as its future product candidates, should Cara resume development activities in the future, and patients who would otherwise be eligible for Cara’s clinical trials may instead enroll in clinical trials of its competitors’ product candidates. Patient enrollment is affected by other factors including:

● the size and nature of the patient population;

● the severity of the disease under investigation;

● the eligibility criteria for, and design of, the trial in question;

● the perceived risks and benefits of the product candidate under study;

● competition in recruiting and enrolling patients in clinical trials;

● the efforts to facilitate timely enrollment in clinical trials;

● the patient referral practices of physicians;

● the ability to monitor patients adequately during and after treatment;

For example, Cara experienced a delay in patient enrollment for its Phase 2 clinical trial of oral difelikefalin for the treatment of pruritus in patients with hepatic impairment due to primary biliary cholangitis that led to Cara’s decision to discontinue and unblind this trial. Should Cara resume development of its product candidate or any future product candidate, Cara could in the future experience similar delays in programs for such product candidates.

Should Cara resume development of its product candidate or any future product candidate, Cara’s inability to enroll a sufficient number of patients for Cara’s clinical trials would result in significant delays and could require Cara to abandon one or more clinical trials altogether. Cara may encounter difficulties and/or delays in completing any future enrollments, should Cara resume development activities in the future. Enrollment delays in Cara’s clinical trials may result in increased development costs for Cara’s product candidate, or the inability to complete development of its product candidate, which would cause the value of Cara to decline, limit Cara’s ability to obtain additional financing, and materially impair Cara’s ability to generate revenues.

Should Cara resume development of its product candidate or any future product candidate, Cara expects to continue to rely on third parties to conduct its preclinical studies and clinical trials, and those third parties may not perform satisfactorily, including failing to meet deadlines for the completion of such trials.

Should Cara resume development of its product candidate or any future product candidate, Cara expects to continue to rely on third parties, such as CROs, clinical data management organizations, medical institutions and clinical investigators, to conduct its preclinical studies and clinical trials. Any agreements Cara may enter into might terminate for a variety of reasons, including a failure to perform by the third parties. If Cara needs to enter into alternative

Table of Contents

arrangements that would delay its product development activities, should Cara resume development of its product candidate or any future product candidate, and adversely affect its business.

Cara’s reliance on these third parties for development activities will reduce its control over these activities. Nevertheless, Cara is responsible for ensuring that each of its studies is conducted in accordance with the applicable protocol, legal, regulatory and scientific standards and its reliance on the CROs does not relieve Cara of its regulatory responsibilities. For example, should Cara resume development activities in the future, Cara will remain responsible for ensuring that each of its clinical trials is conducted in accordance with the general investigational plan and protocols for the trial and for ensuring that Cara’s preclinical trials are conducted in accordance with FDA’s good laboratory practice, or GLP, as appropriate. Moreover, the FDA and comparable foreign regulatory authorities require Cara to comply with standards, commonly referred to as good clinical practices, or GCPs, for conducting, recording and reporting the results of clinical trials to assure that data and reported results are credible and accurate and that the rights, integrity and confidentiality of trial participants are protected. Regulatory authorities enforce these requirements through periodic inspections of trial sponsors, clinical investigators and trial sites. If Cara or any of its CROs fail to comply with applicable GCPs, the clinical data generated in Cara’s clinical trials may be deemed unreliable and the FDA or comparable foreign regulatory authorities may require Cara to perform additional clinical trials before approving its marketing applications. Cara cannot assure you that upon inspection by a given regulatory authority, such regulatory authority will determine that any of Cara’s clinical trials complies with GCP regulations. In addition, Cara’s clinical trials must be conducted with product produced, under current good manufacturing practices, or cGMP, regulations. Cara’s failure to comply with these regulations should Cara resume development activities in the future, may require Cara to repeat clinical trials, which would delay the regulatory approval process. Cara also is required to register certain clinical trials and post the results of certain completed clinical trials on a government-sponsored database, ClinicalTrials.gov, within specified timeframes. Failure to do so can result in fines, adverse publicity and civil and criminal sanctions.

Should Cara resume development activities in the future, CROs Cara engages may also have relationships with other entities, some of which may be Cara’s competitors. In addition, Cara’s CROs would not be its employees, and except for remedies available to Cara under its agreements with such CROs, Cara would not be able to control whether or not they devote sufficient time and resources to its clinical, non-clinical and preclinical programs. If these third parties do not successfully carry out their contractual duties, meet expected deadlines or conduct any future preclinical studies or clinical trials in accordance with regulatory requirements or Cara’s stated protocols, if they need to be replaced or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to any future clinical protocols, regulatory requirements or for other reasons, Cara’s clinical trials, should Cara resume development activities in the future, may be extended, delayed or terminated and Cara may not be able to obtain, or may be delayed in obtaining, marketing approvals for any such product candidate and will not be able to, or may be delayed in its efforts to, successfully commercialize its products and product candidates. As a result, Cara’s results of operations and the commercial prospects for Cara’s products and product candidates would be harmed, Cara’s costs could increase and its ability to generate revenues could be delayed.

If any of Cara’s relationships with a third-party CRO that Cara engages terminates, Cara may not be able to enter into arrangements with alternative CROs or to do so on commercially reasonable terms. Switching or adding additional CROs involves additional cost and requires management time and focus. In addition, there is a natural transition period when a new CRO commences work. As a result, delays could occur, which could compromise Cara’s ability to meet its desired development timelines. Though Cara carefully manages its relationships with its CROs, should Cara resume development activities in the future, there can be no assurance that Cara will not encounter challenges or delays in the future or that these delays or challenges will not have a material adverse impact on Cara’s business, financial condition and prospects.

Table of Contents

Should Cara resume development of its product candidate or any future product candidate, manufacturers upon whom Cara may rely could fail to produce a product candidate in the volumes that Cara may require on a timely basis, or to comply with stringent regulations applicable to pharmaceutical drug manufacturers, and Cara could face delays in the development of a product candidate.

Should Cara resume development of its product candidate or any future product candidate, Cara expects to continue to rely on third parties for the manufacture of any such product candidate for preclinical and clinical testing. If Cara were to experience an unexpected loss of supply of a product candidate for any reason, whether as a result of manufacturing, supply or storage issues or otherwise, Cara could experience delays, disruptions, suspensions or terminations of, or be required to restart or repeat, any clinical studies.

Should Cara resume development of its product candidate or any future product candidate, any problems or delays Cara experiences in preparing for commercial-scale manufacturing of a product or product candidate may result in a delay in FDA approval of the product or product candidate or may impair Cara’s ability to manufacture commercial quantities, which would adversely affect Cara’s business. For example, Cara’s manufacturers would need to produce specific batches of a product or product candidate to demonstrate acceptable stability under various conditions and for commercially viable lengths of time. Cara and its contract manufacturers would need to demonstrate to the FDA and other regulatory authorities acceptable stability data for any product candidate, as well as validate methods and manufacturing processes, in order to receive and maintain regulatory approval to commercialize any approved product candidates. Furthermore, if Cara’s commercial manufacturers fail to deliver the required commercial quantities of bulk drug substance or finished product on a timely basis and at commercially reasonable prices, Cara would likely be unable to meet demand for its product and Cara would lose potential revenues.

The manufacture of pharmaceutical products requires significant expertise and capital investment, including the development of advanced manufacturing techniques and process controls. Manufacturers of pharmaceutical products often encounter difficulties in production, particularly in scaling up initial production. These problems include difficulties with production costs and yields, quality control, including stability of the products and product candidates and quality assurance testing, shortages of qualified personnel, as well as compliance with strictly enforced federal, state and foreign regulations. Manufacturers that Cara engages may not perform as agreed. If manufacturers Cara engages were to encounter any of these difficulties, Cara’s ability to provide products for commercialization and product candidates to patients in any future clinical trials, should Cara resume development activities in the future, would be jeopardized. This could, among other things, lead to increased costs, lost revenue, damage to customer relationships, time and expense spent investigating the cause and, depending on the cause, similar losses with respect to other batches or products. If problems are not discovered before the product is released to the market, recall and product liability costs may also be incurred.

Further, should Cara resume development of its product candidate or any future product candidate, Cara may rely on proprietary technology developed by contract manufacturers for purposes of manufacturing certain of its products and product candidates and Cara’s failure to negotiate or maintain the long-term use of any such proprietary technology or the inability for its contract manufacturers to produce any products and product candidates or components of any products and product candidates in the volumes that Cara requires on a timely basis, may lead to delays or interruptions in the regulatory approval or commercialization process, as well as increased costs. For example, in August 2019, Cara entered into the Enteris License Agreement and intended to use Enteris’s Peptelligence® technology to develop, manufacture and commercialize oral difelikefalin. In light of Cara’s decision to discontinue the development of oral difelikefalin, it is possible that the Enteris License Agreement will be terminated. If Cara decides to resume development of oral difelikefalin in the future, if the Enteris License Agreement has been terminated or, for any other reason, Cara experiences any interruptions in the manufacture, delivery or scale-up of the Enteris formulation technology, Cara may experience delays in the development and commercialization of oral difelikefalin. Further, if Cara is unable to maintain its relationship with Enteris, Cara may be forced to reformulate oral difelikefalin which could significantly delay commercializing oral difelikefalin and require Cara to incur additional costs in connection with such reformulation and potentially needed to seek additional approvals from the FDA. The operations of Cara’s third-party manufacturers have been and, should Cara resume development of its product candidate or any future product candidate, may in the future be constrained or disrupted and their operating capacity may be reduced by public health crises, such

Table of Contents

as pandemics or other similar outbreaks, which could negatively impact Cara’s clinical development and commercialization timelines.

In addition, should Cara resume development of its product candidate or any future product candidate, any manufacturers must comply with cGMP requirements enforced by the FDA through its facilities inspection program. These requirements include quality control, quality assurance and the maintenance of records and documentation. Manufacturers of Cara’s products and product candidates may be unable to comply with these cGMP requirements and with other FDA, state and foreign regulatory requirements. If Cara’s contract manufacturers cannot successfully manufacture material that conforms to Cara’s specifications and the strict regulatory requirements of the FDA or other regulatory authorities, they will not be able to secure and/or maintain regulatory approval for their manufacturing facilities. In addition, regulatory agencies subject an approved product, its manufacturer and the manufacturer’s facilities to continual review and inspections, including periodic unannounced inspections. The subsequent discovery of previously unknown problems with Cara’s current or any future approved products, including adverse events of unanticipated severity or frequency, or problems with the facilities where Cara’s current or any future approved products are manufactured, may result in restrictions on the marketing of Cara’s current or any such future approved products, up to and including withdrawal of the affected product from the market. Cara has little control over its manufacturers’ compliance with these regulations and standards. If the FDA or a comparable foreign regulatory authority does not approve these facilities for the manufacture of its products and product candidate or if it withdraws any such approval in the future, Cara may need to find alternative manufacturing facilities, which would significantly impact Cara’s ability to develop, obtain regulatory approval for or market its products and any product candidate, should Cara resume development of its product candidate or any future product candidate, if approved. A failure to comply with these requirements may result in fines and civil penalties, suspension of production, suspension, delay or denial of product approval, product seizure or recall, or withdrawal of product approval. If the safety of any quantities supplied is compromised due to Cara’s manufacturers’ failure to adhere to applicable laws or for other reasons, Cara may not be able to obtain regulatory approval for or successfully commercialize its products and any potential future product candidates.

Should Cara resume development of its product candidate or any future product candidate, even if Cara obtains regulatory approvals for such product candidate, they may never be successfully launched or become profitable, in which case Cara’s business, prospects, operating results and financial condition may be materially harmed.

In order to successfully launch a product and have it become profitable, should Cara resume development of its product candidate or any future product candidate, Cara anticipates that it will have to dedicate substantial time and resources. Cara’s ability to generate revenues from any commercialized products will depend on a number of factors, including, but not limited to:

● the efficacy and safety of Cara’s product; and

Table of Contents

Because of the numerous risks and uncertainties associated with Cara’s commercialization efforts, Cara may not be able to achieve profitability. For example, Cara previously successfully developed KORSUVA injection through regulatory approval, for the treatment of moderate-to-severe pruritus associated with chronic kidney disease in adults undergoing hemodialysis. However, this product failed to achieve meaningful commercial success.

Even if Cara does achieve profitability, Cara may not be able to sustain or increase profitability on a quarterly or annual basis. A failure to become and remain profitable would depress the value of the company and could impair Cara’s ability to raise capital, expand its business, diversify its product offerings or continue its operations. A decline in the value of the company could also cause you to lose all or part of your investment.

If Cara or its collaborators are unable to establish effective marketing and sales capabilities, or if Cara is unable to enter into or maintain agreements with third parties to market and sell its product and, should Cara resume development of its product candidate or any future product candidate, any product candidate, if they are approved, Cara may be unable to generate product revenues.

Cara currently does not have an internal commercial infrastructure for the marketing, sale, and distribution of pharmaceutical products. Should Cara resume development of its product candidate or any future product candidate, in order to commercialize any such product candidate (if approved) in the United States, Cara will need to build its marketing, sales and distribution capabilities. Cara has no prior experience in the marketing, sale and distribution of pharmaceutical products, and there are significant risks involved in the building and managing of a commercial infrastructure to the extent Cara chooses to do so in the future. The establishment and development of Cara’s own sales force and related plans to market any products in the United States Cara may develop will be expensive and time-consuming and could delay any product launch, and Cara may not be able to successfully develop this capability. Should Cara resume development activities in the future, if oral difelikefalin or any future product candidate is approved for marketing outside of the United States, Cara intends to make and maintain arrangements with third parties to perform these services.

Cara, or its partners or collaborators, will have to compete with other pharmaceutical and biotechnology companies to recruit, hire, train, manage and retain marketing and sales personnel. In the event that Cara or its partners or collaborators are unable to develop a marketing and sales infrastructure, Cara may not be able to commercialize any potential future product candidate, which would limit Cara’s ability to generate product revenues. Factors that may inhibit Cara’s or Cara’s partners’ or collaborators’ efforts to commercialize any potential future product candidate, if approved, include:

Cara’s or Cara’s partners’ or collaborators’ sales force and marketing teams may not be successful in commercializing any approved product candidate that may receive regulatory approval. For example, Cara previously partnered with CSL Vifor for the commercialization of KORSUVA injection, but that product has not achieved meaningful commercial success.

In the event that Cara is unable to successfully collaborate with a third-party marketing and sales organization to commercialize any approved product candidate outside the United States, Cara’s ability to generate product revenues may be limited. To the extent that Cara relies on third parties to commercialize products for which Cara obtains

Table of Contents

regulatory approval, Cara may receive less revenues than if Cara commercialized these products itself. In addition, Cara would have less control over the sales efforts of any other third parties involved in Cara’s commercialization efforts.

Cara faces significant competition from other pharmaceutical and biotechnology companies, academic institutions, government agencies and other research organizations. Cara’s operating results will suffer if it fails to compete effectively.

The development and commercialization of new drug products is highly competitive. Cara faces competition with respect to its current product, KORSUVA injection and, should Cara resume development of its product candidate or any future product candidate, Cara will face competition with respect to any product candidates that it may seek to develop or commercialize in the future, from major pharmaceutical companies, specialty pharmaceutical companies and biotechnology companies worldwide. There are a number of large pharmaceutical and biotechnology companies that currently market and sell products or are pursuing the development of products for the treatment of pruritus. Potential competitors also include academic institutions, government agencies and other public and private research organizations that conduct research, seek patent protection and establish collaborative arrangements for research, development, manufacturing and commercialization.

Among the companies that currently market or are developing therapies in the pruritus space that, if approved, Cara’s oral difelikefalin would potentially compete with include: Pfizer, AbbVie, Eli Lilly, Amgen, Regeneron, Leo Pharma, Galderma, Chugai, Incyte and others.

Cara’s commercial opportunity could be reduced or eliminated if its competitors develop and commercialize products that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than Cara’s product or any future product candidates. Cara’s competitors also may obtain FDA or other regulatory approval for their products more rapidly than Cara may obtain approval for Cara’s, which could result in Cara’s competitors establishing a strong market position before Cara is able to enter the market. In addition, Cara’s ability to compete may be affected in many cases by insurers or other third-party payers seeking to encourage the use of generic products. Should Cara resume development of its product candidate or any future product candidate, generic products may be approved or used in clinical practice in some markets for the indication that such product candidate is intended to treat. Cara expects that any potential future product candidates, if approved, would be priced at a significant premium over competitive generic products, if any.

Many of the companies against which Cara is competing or against which Cara may compete in the future have significantly greater financial resources and expertise in R&D, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved products than Cara does. Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of Cara’s competitors. Early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These third parties compete with Cara in recruiting and retaining qualified scientific and management personnel, establishing clinical trial sites and patient recruitment for clinical trials, as well as in acquiring technologies complementary to, or necessary for, Cara’s programs.

Table of Contents

Cara faces potential product liability exposure, and if successful claims are brought against Cara, Cara may incur substantial liability and, should Cara resume development of Cara’s product candidate or any future product candidate, may have to limit commercialization of a product candidate.

Cara faces an inherent risk of product liability lawsuits related to the sale of its products to, use of its products by, and testing of any product candidate in, seriously ill patients. For example, product liability claims might be brought against Cara by consumers, healthcare providers or others using, administering or selling its products. Cara may be sued if any product it develops allegedly causes injury or is found to be otherwise unsuitable during clinical testing, manufacturing, marketing or sale. Any such product liability claims may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the product, negligence, strict liability or a breach of warranties. If Cara cannot successfully defend itself against these claims, Cara will incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in:

● impairment of Cara’s business reputation or financial stability;

● costs of related litigation;

● substantial monetary awards to patients or other claimants;

● significant negative media attention;

● initiation of investigations by regulators or increased regulatory scrutiny;

● the inability to commercialize any potential product candidate.

Should Cara resume development of its product candidate or any future product candidate, for any product candidate that is approved for commercial sale, Cara will be highly dependent upon healthcare provider and patient perceptions of Cara and the safety and quality of Cara’s products. Cara could be adversely affected if it is subject to negative publicity. Cara could also be adversely affected if any of its products or any similar products distributed by other companies prove to be, or are asserted to be, harmful to patients. Because of Cara’s dependence upon consumer perceptions, any adverse publicity associated with illness or other adverse effects resulting from patients’ use or misuse of Cara’s products or any similar products distributed by other companies could have a material adverse impact on Cara’s financial condition or results of operations.

Cara has obtained limited product liability insurance coverage for its products and its clinical trials with a $5.0 million annual aggregate coverage limit in the United States and various other coverage limits outside of the United States. However, Cara’s insurance coverage may not reimburse it or may not be sufficient to reimburse it for any expenses or losses Cara may suffer. Moreover, insurance coverage is becoming increasingly expensive, and, in the future, Cara may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts to protect it against losses due to liability. Should Cara resume development of its product candidate or any future product candidate, Cara would attempt to expand its insurance coverage to include the sale of commercial products for such product candidate, but may be unable to obtain commercially reasonable product liability insurance for any products approved

Table of Contents

for marketing, or at all. On occasion, large judgments have been awarded in class action lawsuits based on drugs that had unanticipated side effects. A successful product liability claim or series of claims brought against Cara could cause its stock price to fall and, if judgments exceed its insurance coverage, could decrease its cash and adversely affect its business.

Cara may expend its limited resources to pursue a particular product candidate or indication and fail to capitalize on its product candidate or indications that may be more profitable or for which there is a greater likelihood of success.

Because Cara has limited financial and managerial resources, it has focused on developing product candidates for specific indications that Cara believed to be most likely to succeed, in terms of both regulatory approval and commercialization. As a result, Cara may have foregone or delayed, or, should Cara resume development activities in the future, may in the future forgo or delay, pursuit of opportunities with other product candidates or for other indications that may prove to have greater commercial potential. For example, in 2023, Cara terminated the atopic dermatitis program as part of its strategy to focus on its advanced chronic kidney disease and NP programs. Further, in January 2024, Cara announced a prioritization of its pipeline to focus its resources on its late-stage clinical program evaluating oral difelikefalin in chronic pruritus associated with NP and terminated its Phase 3 clinical program evaluating oral difelikefalin in pruritus associated with advanced chronic kidney disease. In June 2024, Cara discontinued the clinical program in NP following the outcome from the dose-finding Part A of the KOURAGE-1 study evaluating the efficacy and safety of oral difelikefalin for moderate-to-severe pruritus in adult patients with NP in which oral difelikefalin did not demonstrate a meaningful clinical benefit at any dose compared to placebo. Cara’s resource allocation decisions may cause it to fail to capitalize on viable commercial products or profitable market opportunities. Should Cara resume development activities in the future, its spending on future R&D programs and product candidates for specific indications may not yield any commercially viable products. If Cara does not accurately evaluate the commercial potential or target market for a particular product candidate, Cara may relinquish valuable rights to that product candidate through collaboration, licensing, or other royalty arrangements in cases in which it would have been more advantageous for Cara to retain sole development and commercialization rights to such product candidate.

Cara’s future growth may depend on its ability to identify and develop products and, should Cara resume development activities in the future, if Cara does not successfully identify and develop product candidates or integrate them into its operations, Cara may have limited growth opportunities.

Should Cara resume development activities in the future, its business strategy may require that it develop a product that it believes is a strategic fit with its focus on pruritus therapeutics. However, these business activities may entail numerous operational and financial risks, including:

● higher than expected development costs;

● exposure to unknown liabilities;

● difficulty in managing multiple clinical trials; and

● inability to successfully develop new products or clinical failure.

Cara has limited resources to identify and execute the development of products. Moreover, Cara may devote resources to potential developments that are never completed, or Cara may fail to realize the anticipated benefits of such efforts. If Cara does not successfully develop and commercialize product candidates, Cara may not be able to obtain product revenues in future periods.

Table of Contents

The regulatory approval processes of the FDA and comparable foreign authorities are lengthy, time consuming and inherently unpredictable. Should Cara resume development activities in the future, if Cara is not able to obtain, or if there are delays in obtaining, required additional regulatory approvals, Cara will not be able to commercialize any product candidates as expected, and Cara’s ability to generate revenue will be materially impaired.

The time required to obtain approval by the FDA and comparable foreign authorities is unpredictable but typically takes many years following the commencement of clinical trials and depends upon numerous factors, including the substantial discretion of the regulatory authorities. In addition, approval policies, regulations, or the type and amount of clinical data necessary to gain approval may change during the course of a product candidate’s clinical development and may vary among jurisdictions. Should Cara resume development of its product candidate or any future product candidate, it is possible that none of such potential product candidates Cara may seek to develop in the future will ever obtain regulatory approval.

Product candidates and the activities associated with their development and commercialization, including their design, testing, manufacture, safety, efficacy, recordkeeping, labeling, storage, approval, advertising, promotion, sale and distribution, are subject to comprehensive regulation by the FDA and other regulatory agencies in the United States and by the EMA, and similar regulatory authorities in other countries. Should Cara resume development of its product candidate or any future product candidate, failure to obtain marketing approval for a product candidate will prevent Cara from commercializing that product candidate. Should Cara resume development activities in the future, Cara expects it would continue to rely on third-party CROs, other vendors, and consultants to assist Cara in filing and supporting the applications necessary to gain marketing approvals. Securing marketing approval requires the submission of extensive preclinical and clinical data and supporting information to regulatory authorities for each therapeutic indication to establish the product candidate’s safety and efficacy for that indication. Securing marketing approval also requires the submission of information about the product manufacturing process to, and inspection of manufacturing facilities by, the regulatory authorities.

Clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain. Failure can occur at any time during the clinical trial process. The results of preclinical studies and early clinical trials of any product candidates, should Cara resume development of its product candidate or any future product candidate, may not be predictive of the results of later-stage clinical trials. Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy traits despite having progressed through preclinical studies and initial clinical trials. A number of companies in the biopharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy or adverse safety profiles, notwithstanding promising results in earlier trials. Should Cara resume development activities in the future, future clinical trial results may not be successful. Cara may also experience numerous unforeseen events during, or as a result of, clinical trials that could delay or prevent Cara’s ability to receive marketing approval or commercialize any product candidates, including:

Table of Contents

● changes in marketing approval policies during the development period;

● changes in or the enactment of additional statutes or regulations;

● changes in regulatory review for each submitted product application;

In addition, unfavorable changes in Cara’s industry or the global economy, including as a result of macroeconomic factors related to fluctuations in inflation and interest rates, political turmoil, or public health crises such as pandemics or other similar outbreaks, could contribute to some of the events listed above and should Cara resume development activities in the future further impact Cara’s ability to progress any future clinical trials, submit for marketing approval or commercialize any product candidates, if approved, as planned. Further, if and to the extent, global health concerns prevent the FDA or other regulatory authorities from conducting their regular inspections, reviews, or other regulatory activities, it could significantly impact the ability of the FDA or other regulatory authorities to timely review and process any additional regulatory submissions Cara may make, which could affect Cara’s ability to obtain marketing approval for any potential product candidate.

Should Cara resume development of its product candidate or any future product candidate, if Cara is unable to successfully complete clinical trials of a product candidate or other testing, if the results of these trials or tests are not positive or are only modestly positive or if there are safety concerns, Cara may:

● not obtain marketing approval at all;

● be subject to additional post-marketing testing requirements; or

● have the product removed from the market after obtaining marketing approval.

Furthermore, regulatory authorities have substantial discretion in the approval process and may refuse to accept any application or may decide that Cara’s data is insufficient for approval and require additional preclinical, clinical or other studies, including with respect to third-party technology used in any potential product candidates. In addition, varying interpretations of the data obtained from preclinical and clinical testing could delay, limit or prevent marketing

Table of Contents

approval of a product candidate. Any marketing approval Cara ultimately obtains may be limited or subject to restrictions or post-approval commitments that render the approved product not commercially viable.

Finally, even if Cara were to obtain approval, regulatory authorities may approve a product candidate for fewer or more limited indications than Cara requests, may grant approval contingent on the performance of costly post-marketing clinical trials, or may approve a product candidate with a label that does not include the labeling claims necessary or desirable for the successful commercialization of that product candidate. Any of these scenarios could compromise the commercial prospects for a product candidate to assure safe use of the product candidate, either as a condition of product candidate approval or on the basis of new safety information.

Should Cara resume development activities in the future, if Cara experiences delays in obtaining approval, if Cara fails to obtain approval of a product candidate or if the label for a product candidate does not include the labeling claims necessary or desirable for the successful commercialization of that product candidate, the commercial prospects for such product candidate may be harmed and Cara’s ability to generate revenues will be materially impaired.

Should Cara resume development of its product candidate or any future product candidate, such product candidate, if approved, could be subject to labeling and other restrictions and market withdrawal and Cara may be subject to penalties if it fails to comply with regulatory requirements or experiences unanticipated problems with its product.

Should Cara resume development of its product candidate or any future product candidate, even if marketing approval of a product candidate is granted, the approval may be subject to limitations on the indicated uses for which the product may be marketed or to the conditions of approval, including any requirement to implement a Risk Evaluation and Mitigation Strategies, or REMS. If a product candidate receives marketing approval, the accompanying label may limit the approved use of Cara’s drug, which could limit sales of the product.

The FDA or other regulatory authorities may also impose requirements for costly post-marketing studies or clinical trials and surveillance to monitor the safety or efficacy of the product. The FDA and other regulatory authorities closely regulate the post-approval marketing and promotion of drugs to ensure drugs are marketed only for the approved indications and in accordance with the provisions of the approved labeling. The FDA and other regulatory authorities impose stringent restrictions on manufacturers’ communications regarding off-label use and if Cara does not market its products for their approved indications, Cara may be subject to enforcement action for off-label marketing. Violations of the Federal Food, Drug, and Cosmetic Act or equivalent regulations outside the United States relating to the promotion of prescription drugs may lead to investigations alleging violations of federal and state health care fraud and abuse laws, as well as state consumer protection laws.

In addition, later discovery of previously unknown AEs or other problems with its products, manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may yield various results, including:

● restrictions on the labeling or marketing of a product;

● restrictions on product distribution or use;

● requirements to conduct post-marketing studies or clinical trials;

● warning letters;

● withdrawal of the products from the market;

Table of Contents

● recall of products and publicity requirements;

● fines, restitution or disgorgement of profits or revenues;

● suspension or withdrawal of marketing or regulatory approvals;

● refusal to permit the import or export of Cara’s products;

● product seizure, detentions or import bans; or

● injunctions or the imposition of civil or criminal penalties.

The FDA’s or other regulatory authorities’ policies may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of any product candidates should Cara resume development of its product candidate or any future product candidate. If Cara is slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if Cara is not able to maintain regulatory compliance, Cara may lose any marketing approval that it may have obtained.

Regulatory approval is limited by the FDA and other regulatory authorities to those specific indications and conditions for which clinical safety and efficacy have been demonstrated, and Cara may be subject to fines, penalties or injunctions if Cara is determined to be promoting the use of its products for unapproved or “off-label” uses, resulting in damage to Cara’s reputation and business.

When the FDA or comparable foreign regulatory authorities issue regulatory approval for a product candidate, the regulatory approval is limited to those specific indications for which a product is approved. If Cara is not able to obtain FDA approval for any desired future indications for its products and product candidates, should Cara resume development of its product candidate or any future product candidate, Cara’s ability to effectively market and sell its products may be reduced and its business may be adversely affected.

While physicians may choose to prescribe drugs for uses that are not described in the product’s labeling and for uses that differ from those tested in clinical studies and approved by the regulatory authorities, Cara is prohibited from marketing and promoting the products for indications that are not specifically approved by the FDA or other regulatory authorities. These “off-label” uses are common across medical specialties and may constitute an appropriate treatment for some patients in varied circumstances. Regulatory authorities in the United States and other countries generally do not restrict or regulate the behavior of physicians in their choice of treatment within the practice of medicine. Regulatory authorities do, however, restrict communications by pharmaceutical companies on off-label use. If the FDA or other regulatory authorities determine that Cara or Cara’s commercial partners’ promotional activities constitute promotion of an off-label use, it could request that Cara modify its promotional materials. Further, off-label promotion could subject Cara to regulatory or enforcement actions by the FDA and other authorities, including issuance of warning letters or untitled letters, suspension or withdraw an approved product from the market, mandatory or voluntary recalls, civil fines, disgorgement of money, operating restrictions, additional reporting requirements and/or oversight if Cara becomes subject to a corporate integrity agreement or similar agreement, injunctions or criminal prosecution, any of which could significantly harm Cara’s business.

Should Cara resume development of its product candidate or any future product candidate, failure to obtain marketing approval in international jurisdictions would prevent a product candidate from being marketed abroad.

In order to market and sell products in the EU and many other jurisdictions, Cara or its collaborators or partners must obtain separate marketing approvals and comply with numerous and varying regulatory requirements. Even if Cara obtains FDA approval of a product candidate, the regulatory approval procedure varies among countries and can involve additional testing. The time required to obtain approval may differ substantially from that required to obtain FDA approval. The regulatory approval process outside the United States generally includes all of the risks associated with obtaining FDA approval. In addition, in many countries outside the United States, it is required that the product be

Table of Contents

approved for reimbursement before the product can be approved for sale in that country. Cara or these third parties may not obtain approvals from regulatory authorities outside the United States on a timely basis, if at all. Approval by the FDA does not ensure approval by regulatory authorities in other countries or jurisdictions, and approval by one regulatory authority outside the United States does not ensure approval by regulatory authorities in other countries or jurisdictions or by the FDA. However, the failure to obtain approval in one jurisdiction may compromise Cara or its collaborators’ or partners’ ability to obtain approval elsewhere. Cara or its collaborators or partners may not be able to file for marketing approvals and may not receive necessary approvals to commercialize its products in any market.

Cara’s agreements with HCR contain various covenants and other provisions, which, if violated, could materially adversely affect Cara’s financial condition.

During the fourth quarter of 2023, Cara, through Cara Royalty Sub, entered into the Original HCR Agreement with HCR, pursuant to which Cara Royalty Sub sold, or agreed to sell, to HCR the Royalties under the Covered License Agreements, in exchange for up to $40.0 million. Cara has retained all of its rights, title and interest in, to and under the Covered License Agreements that relate to any non-intravenous formulation of difelikefalin.

Under the terms of the Original HCR Agreement, Cara received an initial payment of $17.5 million less certain transaction costs in November 2023. In December 2023, Cara received an additional $20.0 million less certain advisory fees, upon satisfying the milestone event for pricing for Kapruvia® (difelikefalin) in Germany being approved above a certain threshold amount per dose. The terms of the Original HCR Agreement also provide for an additional $2.5 million milestone payment to Cara Royalty Sub upon achievement of a 2024 sales milestone of KORSUVA in Japan, which was achieved in the fourth quarter of 2024 and is expected to be paid in the first quarter of 2025.

On December 17, 2024, the Sellers entered into the APA with CSL Vifor, pursuant to which, at the consummation of the transaction, Sellers will sell to CSL Vifor and CSL Vifor will acquire from Sellers certain assets and rights for the development, manufacture and commercialization of difelikefalin as well as certain associated liabilities, or the Asset Disposition, for a purchase price of $900,000 (subject to certain adjustments with respect to inventory). Pursuant to the APA, in connection with the consummation of the Asset Disposition, CSL Vifor and HCR have entered into a letter agreement with Cara providing that CSL Vifor and HCR will, subject to the satisfaction of conditions to closing under the APA, enter into an amended and restated purchase agreement to amend and replace the Original HCR Agreement. Upon entering into the amended and restated purchase agreement, effective as of the closing of the Asset Disposition: (i) CSL Vifor will be obligated to make certain payments to HCR from and after the date thereof relating to certain revenue and/or royalties from difelikefalin, (ii) each of the Contribution Agreement, the License Agreement and the Pledge Agreement (each as defined in the Original HCR Agreement) shall be terminated, and (iii) Sellers shall have no further payment or other obligations to HCR under the Original HCR Agreement. Additionally, pursuant to the APA, at the consummation of the Asset Disposition, Cara has agreed to pay CSL Vifor $3.0 million to compensate CSL Vifor for the estimated incremental future expenses to be incurred by CSL Vifor as a result of the transfer of the assets to be acquired and the liabilities to be assumed by it in connection with the Asset Disposition.

Table of Contents

consummation of the Asset Disposition, and (iii) Sellers to use their commercially reasonable efforts to obtain any needed consents and provide any needed notices in connection with the Asset Disposition.

If the above transactions are not approved/consummated, the Original HCR Agreement will automatically expire, and the payment of Royalties to HCR will cease, when HCR has received payments of Royalties equal to two times the aggregate amount of payments made by HCR under the Original HCR Agreement if achieved on or prior to December 31, 2029, or 2.8 times the aggregate amount of payments made by HCR under the Original HCR Agreement, if the 2029 Threshold is not achieved on or prior to December 31, 2029. In the event of a change of control, Cara Royalty Sub will pay to HCR an amount equal to 2.8 times the aggregate amount of payments made by HCR less the total net amounts paid by Cara Royalty Sub to HCR as of the effective date of control. In certain situations, Cara Royalty Sub would not be obligated to pay the change of control payment to HCR. After the Original HCR Agreement expires, all rights to receive the Royalties return to Cara Royalty Sub.

In connection with the HCR Agreement, Cara entered into a Contribution and Servicing Agreement which contains various representations and warranties, covenants, indemnification obligations and other provisions related to the contribution of the Covered License Agreement to Cara Royalty Sub and its maintenance and servicing obligations with respect to the Royalties and the Covered License Agreements. In the event Cara violates these covenants or provisions, Cara may lose the right to act as the servicer of Cara Royalty Sub and a third-party servicer may be appointed at Cara Royalty Sub’s expense. Cara’s replacement as servicer, if it were to occur, could have a material adverse effect on Cara’s financial condition as HCR, by virtue of owning Cara Royalty Sub, would own the Royalties.

In connection with the Original HCR Agreement, Cara also entered into a Pledge and Security Agreement containing various representations, warranties and covenants, and a limited recourse guaranty of Cara Royalty Sub’s obligations under the Purchase and Sale Agreement which is secured by the pledge in favor of HCR all of the capital stock of Cara Royalty Sub. HCR is entitled to foreclose on the capital stock of Cara Royalty Sub following the occurrence of certain remedies events, including, without limitation, a bankruptcy of Cara or the failure of Cara to perform its obligations under the Contribution and Servicing Agreement. Such foreclosure, if it were to occur, could have a material adverse effect on Cara’s financial condition as HCR, by virtue of owning Cara Royalty Sub, would own the Royalties.

Cara’s information systems, or those of others upon whom Cara relies (such as Cara’s CROs, contract manufacturers, contractors, consultants, service providers, collaborators and others) may fail or suffer cybersecurity breaches, loss or leakage of data or other disruptions, which could result in a material disruption of Cara’s development programs, compromise sensitive information related to Cara’s business, or prevent Cara from accessing critical information, potentially exposing Cara to liability that could adversely affect Cara’s business.

Cara is increasingly dependent upon information systems, infrastructure and data to operate its business. In the ordinary course of business, Cara collects, stores, transmits and otherwise processes confidential information (including but not limited to intellectual property, proprietary business information and personal data). Cara also has outsourced elements of its operations to third parties, and as a result Cara manages a number of service providers who have access to its data and information systems and infrastructure. Cara’s reliance on service providers could introduce new cybersecurity risks and vulnerabilities, including supply-chain attacks, and other threats to Cara’s business operations.Cara relies on service providers and technologies to operate critical business systems to process sensitive data in a variety of contexts, including, without limitation, cloud-based infrastructure, data center facilities, encryption and authentication technology, personnel email, and other functions. Cara also relies on third-party service providers to provide other products, services, parts, or otherwise to operate its business. Cara’s ability to monitor these third parties’ information security practices is limited, and these third parties may not have adequate information security measures in place. If Cara’s third-party service providers experience a security incident or other interruption, Cara could experience adverse consequences. While Cara may be entitled to damages if its third-party service providers fail to satisfy their privacy or security-related obligations to Cara, any award may be insufficient to cover Cara’s damages, or Cara may be unable to recover such award.In addition, supply-chain attacks have increased in frequency and severity, and Cara cannot guarantee that third parties’ infrastructure in Cara’s supply chain or its third-party partners’ supply chains have not been compromised.

Table of Contents

Cybersecurity risks have significantly increased in recent years in part because of the proliferation of new technologies, the use of the internet and telecommunication technologies to conduct financial transactions, especially as personnel are working remotely, and the increased sophistication and activities of organized crime, hackers, terrorists, nation-states and other external parties. To the extent that any disruption or cybersecurity breach were to result in a loss of, or damage to, Cara’s data or information systems, or inappropriate disclosure of confidential or proprietary information, Cara could incur liability and reputational damage and, should Cara resume development of its product candidate or any future product candidate, the further development of such product candidates could be delayed.

Some actors now engage and are expected to continue to engage in cyberattacks, including without limitation nation-state actors for geopolitical reasons and in conjunction with military conflicts and defense activities. During times of war and other major conflicts, Cara, and the third parties upon which Cara relies, may be vulnerable to a heightened risk of these attacks, including retaliatory cyberattacks, that could materially disrupt its systems and operations, supply chain, and ability to produce, sell and distribute Cara’s goods and services. In particular, severe ransomware attacks are becoming increasingly prevalent and can lead to significant interruptions in Cara’s operations, ability to provide its products or services, loss of sensitive data and income, reputational harm, and diversion of funds. Extortion payments may alleviate the negative impact of a ransomware attack, but Cara may be unwilling or unable to make such payments due to, for example, applicable laws or regulations prohibiting such payments.

Cara and the third parties upon which Cara relies are subject to a variety of evolving threats, including but not limited to social-engineering attacks (including through deep fakes, which may be increasingly more difficult to identify as fake, and phishing attacks), malicious code (such as viruses and worms), malware (including as a result of advanced persistent threat intrusions), denial-of-service attacks, credential stuffing, credential harvesting, personnel misconduct or error, ransomware attacks, supply-chain attacks, software bugs, server malfunctions, software or hardware failures, loss of data or other information technology assets, adware, attacks enhanced or facilitated by AI, telecommunications failures, earthquakes, fires, floods, and other similar threats. Additionally, future or past business transactions (such as acquisitions or integrations) could expose Cara to additional cybersecurity risks and vulnerabilities, as Cara’s systems could be negatively affected by vulnerabilities present in acquired or integrated entities’ systems and technologies. Furthermore, Cara may discover security issues that were not found during due diligence of such acquired or integrated entities, and it may be difficult to integrate companies into Cara’s information technology environment and security program.

While Cara has implemented security measures designed to protect against security incidents, there can be no assurance that these measures will be effective. Cara takes steps designed to detect, mitigate, and remediate vulnerabilities in its information systems (such as its hardware and/or software, including that of third parties upon which Cara relies). Cara may not, however, detect and remediate all such vulnerabilities including on a timely basis. Further, Cara may experience delays in developing and deploying remedial measures and patches designed to address identified vulnerabilities. Vulnerabilities could be exploited and result in a security incident.

Any of the previously identified or similar threats could cause a security incident or other interruption that could result in unauthorized, unlawful, or accidental acquisition, modification, destruction, loss, alteration, encryption, disclosure of, or access to Cara’s sensitive data or Cara’s information technology systems, or those of the third parties upon whom Cara relies. A security incident or other interruption could disrupt Cara’s ability (and that of third parties upon whom Cara relies) to provide its services.

Cara may expend significant resources or modify its business activities to try to protect against security incidents. Additionally, certain data privacy and security obligations may require Cara to implement and maintain specific security measures or industry-standard or reasonable security measures to protect its information technology systems and sensitive data.

Applicable data privacy and security obligations may require Cara to notify relevant stakeholders, including affected individuals, customers, regulators, and investors, of security incidents. Such disclosures are costly, and the disclosure or the failure to comply with such requirements could lead to adverse consequences.

Table of Contents

If Cara (or a third party upon whom Cara relies) experiences a security incident or is perceived to have experienced a security incident, it may experience material adverse consequences, such as government enforcement actions (for example, investigations, fines, penalties, audits, and inspections); additional reporting requirements and/or oversight; restrictions on processing sensitive data (including personal data); litigation (including class claims); indemnification obligations; negative publicity; reputational harm; monetary fund diversions; diversion of management attention; interruptions in Cara’s operations (including development and commercialization of any product candidate, should Cara resume development activities in the future, if approved, and availability of data); financial loss; and other similar harms. Security incidents and attendant material consequences may prevent or cause customers to stop using Cara’s services, deter new customers from using Cara’s services, and negatively impact Cara’s ability to grow and operate its business.

Cara’s contracts may not contain limitations of liability, and even where they do, there can be no assurance that limitations of liability in its contracts are sufficient to protect Cara from liabilities, damages, or claims related to Cara’s data privacy and security obligations. Cara cannot be sure that its insurance coverage will be adequate or sufficient to protect it from or to mitigate liabilities arising out of Cara’s privacy and security practices, that such coverage will continue to be available on commercially reasonable terms or at all, or that such coverage will pay future claims.

Risks Related to Cara’s Dependence on Third Parties

Any collaboration arrangements that Cara is a party to or may enter into in the future may not be successful, which, should Cara resume development activities, could adversely affect Cara’s ability to develop and ultimately commercialize its product candidate or any potential future product candidate.

Cara’s business model in the past has been to develop and commercialize product candidates in the United States and generally to seek collaboration arrangements with pharmaceutical or biotechnology companies for the development or commercialization of product candidates in the rest of the world. Cara currently has license agreements with Maruishi and CKDP for the intravenous and oral formulations of difelikefalin, as well as license agreements with respect to its commercially approved products, KORSUVA Injection and Kapruvia with CSL Vifor. Should Cara resume development activities, in addition to its existing agreements, Cara may enter into additional collaboration arrangements in the future on a selective basis. Cara’s existing collaborations and future collaboration arrangements may not be successful. The success of Cara’s existing and future collaboration arrangements will depend heavily on the efforts and activities of its collaborators.

Collaborators generally have significant discretion in determining the efforts and resources that they will apply to these collaboration arrangements. Disagreements between parties to a collaboration arrangement regarding clinical development and commercialization matters can lead to delays in the development process or commercializing the applicable product candidate and, in some cases, termination of the collaboration arrangement. These disagreements can be difficult to resolve if neither of the parties has final decision-making authority.

Collaborations with pharmaceutical companies and other third parties often are terminated or allowed to expire by the other party. Maruishi may terminate its agreement with Cara at will, and CKDP may terminate its agreement with Cara in certain circumstances relating to patent invalidity or unenforceability or generic entry by a third party, as further described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Collaboration and License Agreements.” Any such termination or expiration could adversely affect Cara financially and could harm Cara’s business reputation. Cara’s current collaborations and any future collaborations Cara might enter into, including related to development of Cara’s product candidate or any future product candidate should Cara resume development activities in the future, may pose a number of risks, including the following:

● collaborators may not perform their obligations as expected;

If Cara’s current collaborations or any other collaborations Cara might enter into in the future, including related to development of its product candidate or any future product candidate should Cara resume development activities in the future, do not result in the successful development and commercialization of products or if one of Cara’s collaborators terminates its agreement with Cara, Cara may not receive any future research funding or milestone or royalty payments under the collaboration. If Cara does not receive the funding it expects under these agreements, Cara’s development of potential product candidates could be delayed and Cara may need additional resources to develop a product candidate and product platform. All of the risks relating to Cara’s product development, regulatory approval and commercialization described in this Annual Report on Form 10-K also apply to the activities of Cara’s collaborators in their respective jurisdictions.

Additionally, if any current or future collaborator of Cara, including related to development of Cara’s product candidate or any future product candidate should Cara resume development activities in the future, is involved in a business combination, the collaborator might deemphasize or terminate development or commercialization of any

product candidate licensed to it by Cara. If one of Cara’s collaborators terminates its agreement with Cara, Cara may find it more difficult to attract new collaborators and Cara’s reputation in the business and financial communities could be adversely affected.

If Cara determines to collaborate in the future with additional pharmaceutical or biotechnology companies for the development and potential commercialization of oral difelikefalin or any potential future product candidate, should Cara resume development activities in the future, Cara would face significant competition in seeking appropriate collaborators. Cara’s ability to reach a definitive agreement for collaboration will depend, among other things, upon Cara’s assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration and the proposed collaborator’s evaluation of a number of factors. If Cara is unable to reach agreements with suitable collaborators on a timely basis, on acceptable terms, or at all, Cara may have to curtail the development of a product candidate, reduce or delay its development program or one or more of Cara’s other development programs, delay its potential commercialization or reduce the scope of any sales or marketing activities, or increase Cara’s expenditures and undertake development or commercialization activities at Cara’s own expense. If Cara elects to fund and undertake development or commercialization activities on its own, Cara may need to obtain additional expertise and additional capital, which may not be available to Cara on acceptable terms or at all. If Cara fails to enter into collaborations and does not have sufficient funds or expertise to undertake the necessary development and commercialization activities, Cara may not be able to further develop product candidates or bring them to market or to develop a product platform or successfully commercialize Cara’s products and business may be materially and adversely affected.

Risks Related to Legal and Compliance Matters

If Cara fails to comply with federal and state healthcare laws, including fraud and abuse, and transparency laws, Cara could face substantial penalties and its business, results of operations, financial condition and prospects could be adversely affected.

As a pharmaceutical company, even though Cara does not and will not control referrals of healthcare services or bill directly to Medicare, Medicaid or other third-party payers, certain federal and state healthcare laws and regulations pertaining to fraud and abuse, transparency and patients’ rights may be applicable to Cara’s business. The healthcare laws and regulations that may affect Cara’s ability, and its partners’ and collaborators’ ability, to operate include, but are not limited to:
