  25. Compensation Program Objectives and Philosophy

    | • | Pay for Performance. Our compensation model should deliver compensation at or above industry market levels for exceptional performance and deliver compensation below the market levels of our industry for years in which the Company does not perform well. Further, all of the time-based equity awards are granted as stock options, which we believe are also inherently performance based as they only provide value to the executive if stockholders realize a positive return on their investment. |

  26. Core Compensation Principles and Practices

    | ☒ | Pay-for-Performance. A substantial majority of the compensation awarded to our NEOs is either tied to specific company-wide goals or have been made in the form of stock option awards that will only have value if the price of our stock increases after the grant date. There were no full value equity awards that guarantee value if the stock price does not increase, also known as restricted share or restricted stock units, granted to NEOs in 2024. |

  27. Core Compensation Principles and Practices

    | ☒ | Periodic Peer Group Review. The compensation committee periodically reviews the Company’s compensation peer group and uses the market data for context, although it does not target any specific percentile. |

  28. Core Compensation Principles and Practices

    | ☒ | Double Trigger. Our severance policy (the “Severance Policy”) only provides our executive officers with acceleration of unvested equity awards held by them if they are terminated (without cause or constructively) in connection with a change of control transaction or within 18 months following a change of control transaction. We do not provide accelerated vesting of equity awards on a change in control alone. |

  29. Core Compensation Principles and Practices

    | ☒ | Reasonable Post-Employment and Change of Control Severance Arrangements. We believe that our severance arrangements with our executive officers are reasonable and in line with industry practice. |

  30. Core Compensation Principles and Practices

    | ☒ | Regular Review of Share Utilization for Equity Compensation. We regularly evaluate equity spending by reviewing overhang levels (the dilutive impact of equity compensation on stockholders) and annual run rates (the aggregate shares awarded as a percentage of total outstanding shares). |

  31. Core Compensation Principles and Practices

    | ☒ | Mitigate Undue Risk. We have designed our executive compensation program to mitigate undue risk associated with compensation by, among other things, awarding a substantial portion of executive compensation in the form of long-term compensation with multi-year vesting (i.e. stock options with multi-year vesting requirements). |

  32. Core Compensation Principles and Practices

    | ☒ | No Stock Option Repricing Without Stockholder Approval. Our equity incentive plans prohibit us from repricing, exchanging or otherwise providing value for underwater stock options. |

  33. Core Compensation Principles and Practices

    | ☒ | No Inclusion of the Value of Equity Awards in Severance Calculations. Our post-termination and change of control severance arrangements do not include the value of equity awards in annual compensation for purposes of determining cash severance amounts. |

  34. Design and Elements of Our Compensation Program

    | 2. | Short-Term Incentive Compensation. Each NEO was eligible to earn an incentive cash compensation payment for the 2024 performance period based on qualitative assessment of the Company’s progress against its corporate goals and his individual performance and/or contribution to such progress. The purpose is to drive short-term performance as milestones towards the goal of creating long-term value for stockholders. |

  35. Design and Elements of Our Compensation Program

    | 3. | Long-Term Incentive Compensation. Each NEO was awarded a stock option grant during 2024, subject to a time-based vesting schedule. The purpose of the stock option grants is to reward growth in the stock price without a guarantee of value if there is no stock price growth after grant, with a multi-year vesting schedule to support retention of key employees and a long-term value orientation. |

  36. Use of Peer Company Data

    Use of Peer Company Data We periodically review the compensation practices of our peer group companies identified below, and we consider the following factors: geographical region, company stage of development, company size and market capitalization. As a result of the Company having a combination of multiple drug candidates in diverse therapeutic areas, a mix of wholly-owned and partnered drug candidates, and a technology platform with the potential to enable multiple drug candidates in future years, it is very challenging to identify truly comparable companies. The peers from which benchmark compensation information was reviewed were of similar size and commercial stage. The Company’s 2024 compensation decisions were made prior to the start of the year using data from a 2022 study of similar companies with median 2022 market capitalization that was close to our 2022 market capitalization size at the time the peers were chosen. Most peer companies reviewed in 2023 were drug development and vaccine companies, as follows:

  37. Use of Peer Company Data

    | AnaptysBio Arbutus BioPharma Cytokinetics Editas Epizyme Geron Heron Therapeutics Inovio Pharmaceuticals Kura Oncology | RegenXBio Sangamo Sorrento Therapeutics Sutro BioPharma Travere Therapeutics Vaxart Viking Therapeutics WaVe Life Sci |

  38. Use of Peer Company Data

    The 2024 equity compensation decisions were made using updated peer group data as context. During 2024, the outside compensation committee and F.W. Cook, facilitated determination of the composition of our 2024 peer group used as market context for 2024 equity compensation decisions. The committee considered generally commercial stage companies with broadly similar market capitalization to recognize the expected commercial sales of ARCT-154 that began in the fourth quarter of 2024. The 2024 peer group of companies reviewed as context when determining 2024 equity compensation decisions and 2025 cash compensation decisions consisted of the following companies:

  39. Use of Peer Company Data

    | ACADIA | Ironwood | | Blueprint | Novavax | | Coherus | PTC | | Collegium | Travere | | Corcept | Ultragenyx | | Dynavax | Vanda | | Heron | Vir Biotechnology | | Insmed | |

  40. Use of Peer Company Data

    We do not set compensation at any specific level or percentile based solely on the peer group data, although we reviewed and discussed the compensation data for the peer group companies to help inform executive compensation decisions. . The peer group data is used by us as only one reference point taken into account in making compensation decisions. We do not use peer group or industry survey data as a standalone tool for setting compensation due to the unique aspects of our business and the need to attract and retain particular highly qualified executives with unique experience, skills and other individual facts and circumstances. However, we generally believe that reviewing and analyzing this information is an important component of our executive compensation decision-making process. The cash compensation of all NEOs in 2024 was at or below the median of the 2024 compensation peer group and equity award values and total compensation values was also set below the median of the 2024 peer group for all of the NEOs in this proxy.

  41. Short-Term Incentive Compensation

    Short-Term Incentive Compensation Incentive Compensation Policy. We believe that our short-term incentive compensation program (“Incentive Compensation Policy”) for the NEOs rewards the achievement of important short-term objectives that advance us toward our long-term strategic objectives. Our Incentive Compensation Policy applies to all executive officers. Consistent with our compensation philosophy of paying for performance and maintaining a flexible approach, we use the Incentive Compensation Policy to incentivize the NEOs to achieve important corporate goals while at the same time encouraging and rewarding excellent individual performance by recognizing and rewarding differences in performance between individual executives. Plan Design. The board of directors establishes important annual corporate goals each year that include clinical development, research, manufacturing, organizational and financial goals which we believe are essential to building long-term stockholder value and are used to assess annual corporate performance. The corporate objectives are not weighted formally nor were they formally tied to a cash bonus plan in 2024, so there is a degree of qualitative judgment in the final score. After 2024 corporate performance was determined, the individual performance and future contribution of NEOs was reviewed by the compensation committee in consultation with Mr. Payne (other than his own performance). Mr. Payne’s individual performance is separately reviewed by the compensation committee. Target Annual Short-Term Incentive Compensation for 2024. The NEOs were each assigned a target annual incentive for 2024 ranging from 40% to 60% of base salary. The table below shows the target annual incentive assigned by us to each NEO for 2024 both as a dollar amount and as a percentage of base salary.

  42. Short-Term Incentive Compensation

    | Name | Target Annual Incentive for 2024 ($) | Target Annual Incentive for 2024 (% of Base Salary) | | Joseph E. Payne | 417,000 | 60 | | Dr. Padmanabh Chivukula | 275,000 | 50 | | Andy Sassine | 275,000 | 50 | | Lance Kurata | 200,000 | 40 |

  45. Actual Annual Incentives Earned for 2024

    Actual Annual Incentives Earned for 2024 The board of directors also recognized certain accomplishments directly related to management efforts including those listed above in Company Performance Highlights. The compensation committee, in consultation with Mr. Payne, determined that the individual contribution of each NEO was critical to the Company’s successful 2024 performance. Given the Company’s corporate objectives, bonuses for 2024 were paid to each of the NEOs as follows: 88% of Mr. Payne’s target bonus, 83% of Dr. Chivukula’s target bonus, 95% of Mr. Sassine’s target bonus, and 90% of Mr. Kurata’s target bonus. The amount of each NEO’s bonus for the 2024 fiscal year is reported in the Summary Compensation Table, and all were higher than the bonuses paid in the year prior.

  46. Long-Term Incentive Compensation: Equity Awards

    Long-Term Incentive Compensation: Equity Awards In accordance with our objective of aligning executive compensation with our stockholders’ interests, our current long-term incentive program for the NEOs generally consists of an annual award of equity compensation that is subject to a multi-year vesting or earn-out schedule. We believe that equity compensation is an effective tool for aligning the interests of our NEOs with the interests of our stockholders. Stock options are our preferred form of long-term incentive compensation because we believe they are inherently performance-based, with value delivered only if the price of our common stock appreciates following the grant. The value of options reported as long-term incentive compensation awards to the NEOs during 2024 was lower than the value reported in the Summary Compensation Table of the 2023 proxy statement for all NEOs, and the grant values provided to all NEOs was below the median of the 2024 compensation peer data available to the Company at the time awards were made.

  47. Equity Compensation Policy

    Equity Compensation Policy While we do not have a formal written policy in place with regard to the timing of certain equity awards in relation to the disclosure of material nonpublic information, our Board and the compensation committee of the Board do not seek to time equity grants to take advantage of information, either positive or negative, about our Company that has not been publicly disclosed. It has been our practice generally to grant initial equity awards to our officers and non-employee directors in connection with their hiring or appointment to the Board, as applicable. We generally intend to issue equity awards to our officers at approximately the same time each year, typically in close proximity to the end of the fiscal year. In addition, non-employee directors generally receive grants of initial and annual equity awards, at the time of a director’s initial appointment or election to the Board and at the time of each annual meeting of our stockholders, respectively, pursuant to our director compensation policy. Option grants generally are effective on the date the award determination is made by the compensation committee or the Board, as the case may be, and the exercise price of options is typically based upon the Fair Market Value of our common stock as defined in our 2019 Omnibus Equity Incentive Plan, as amended and restated (the “2019 Plan”). During the fiscal year ended December 31, 2024, we did not award any equity awards to a named executive officer in the period beginning four business days before the filing of a periodic report on Form 10-Q or Form 10-K, or the filing or furnishing of a current report on Form 8-K that discloses material nonpublic information, and ending one business day after the filing or furnishing of such report.

  48. Severance and Change of Control Benefits

    Severance and Change of Control Benefits If the employment of an NEO is terminated by us without cause or by the NEO for a designated good reason outside of the context of a change of control transaction, the NEO would be entitled to severance benefits under his employment agreement with the Company. These severance benefits include a cash severance payment based on the NEO’s then-current base salary and a pro rata amount of his annual incentive bonus, and payment of COBRA premiums. In order to attract and retain these NEOs in a competitive environment for highly skilled senior executive talent in the biotechnology and pharmaceutical industry and to provide an incentive to obtain a broad release of claims in favor of the Company, we determined it was beneficial to offer each of them severance protection in the case of a termination without cause or constructive termination outside the context of a change of control transaction. These NEOs would also be entitled to certain termination benefits upon a termination of employment because of death or disability. In April 2021, after consulting with the compensation committee’s independent compensation consultant, the Board adopted a written Severance Policy covering all senior executives of the Company. Termination and change of control payments under the Severance Policy are without duplication of any severance payments provided for in an individual employment agreement (such that the higher amount would apply). The primary changes effected by the Severance Policy are to (i) implement new and more internally equitable amounts for cash severance, (ii) make certain clean-up changes to the severance provisions in the NEOs’ employment agreements (the “Employment Agreements”), and (iii) require non-solicitation and non-disparagement restrictive covenants as a condition of receiving severance. Pursuant to the Severance Policy, the NEOs are entitled to certain severance benefits if their employment is terminated in connection with a change of control. Severance benefits under the Severance Policy are structured on a “double-trigger” basis, meaning that the executive must experience a termination without cause or resign for a specifically defined good reason in connection with the change of control in order for severance benefits to become payable under the Severance Policy. Like the severance benefits under the Employment Agreements, we believe that these change of control severance benefits are an important element of a competitive total compensation program. Additionally, we believe that providing change of control benefits should eliminate, or at least reduce, any reluctance of our NEOs and other key employees covered by the Severance Policy to diligently consider and pursue potential change of control opportunities that may be in the best interests of our stockholders. At the same time, by providing change of control benefits only upon the occurrence of an additional triggering event occurring in connection with the change of control transaction resulting in a job loss, we believe that this Severance Policy helps preserve the value of our key personnel for any potential acquiror. Under the Severance Policy, the executive would be entitled to accelerated equity award vesting if their employment is terminated within 18 months of a change of control. The other severance benefits under the Severance Policy are generally similar to the severance benefits described above, provided that (i) the executive is also entitled to a lump sum payment in an amount equal to his target annual bonus for the year of termination, (ii) pro-rata target bonus for the year of termination, and (iii) Company-paid COBRA coverage is extended by several additional months. The “Potential Payments Upon Termination or Change of Control” section below describes and quantifies the severance and other benefits potentially payable to the NEOs.

  56. POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

    POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL See “Current Agreements With Our Named Executive Officers” for a description of the circumstances that would trigger payments or the provision of other benefits to each of our named executive officers in connection with their termination without cause or resignation for good reason in connection with a change in control. See “Termination and Change of Control Potential Payments and Benefits Table” for details on the amounts of such payments. Under the employment agreements with our named executive officers, “good reason” constitutes a resignation from employment with the Company in connection with the occurrence of any of the following without the executive’s prior written consent: (i) a material reduction in the executive’s base salary, unless pursuant to a salary reduction program applicable generally to the Company’s senior executives; (ii) a material reduction in the executive’s duties (including responsibilities and/or authorities), provided that (A) a change in job position (including a change in title) shall not be deemed a “material reduction” in and of itself unless the executive’s new duties are materially reduced from the prior duties, and (B) a reduction in duties which results from the hiring of an individual not previously employed by the Company to serve as its President and/or Chief Executive Officer shall not be deemed a “material reduction” (e.g., where an executive undertakes temporary additional responsibilities until a President and/or Chief Executive Officer is appointed); or (iii) relocation of the executive’s principal place of employment to a place that increases the executive’s one-way commute by more than 50 miles as compared to the executive’s then-current principal place of employment immediately prior to such relocation. In order for an executive to resign for good reason, each of the following requirements must be met: (i) the executive must provide written notice to the Board within 30 days after the first occurrence of the event giving rise to good reason setting forth the basis for the executive’s resignation, (ii) the executive must allow the Company at least 30 days from receipt of such written notice to cure such event, (iii) such event is not reasonably cured by the Company within such 30 day period (the “Cure Period”), and (iv) the executive must resign from all positions the executive then holds with the Company not later than 30 days after the expiration of the Cure Period. Effective May 1, 2021, the Board adopted a written Severance Policy covering all senior executives of the Company. Termination and change of control payments under the Severance Policy will not duplicate any severance payments provided for in an individual employment agreement (such that the higher amount would apply). For a summary of the Severance Policy, see “Severance and Change of Control Benefits.” Pursuant to the Severance Policy, in order to receive any payments upon a termination or change of control, our named executive officers must execute a general release of all known and unknown claims, as drafted in the Company’s discretion, in a severance agreement acceptable to the Company within the applicable deadline set forth therein, but in no event later than twenty-one days following the executive’s termination date, and permit the release to become effective and irrevocable in accordance with its terms. Options granted to our officers and certain of our directors may contain acceleration provisions upon certain merger, acquisition, or change of control transactions. If the relationship between us and an executive officer or a director is terminated, except for cause (as defined in the various option plan agreements), options that are vested will generally remain exercisable for ninety days or thirty-six months after such termination depending on whether the options were granted to an executive officer or director. Generally, any benefits conferred on an executive officer as a result of a change of control require such officer to execute a signed and dated general release of known and unknown claims in a termination agreement acceptable to the Company.

  57. TERMINATION AND CHANGE OF CONTROL POTENTIAL PAYMENTS AND BENEFITS TABLE

    TERMINATION AND CHANGE OF CONTROL POTENTIAL PAYMENTS AND BENEFITS TABLE The amounts disclosed in the table below are based on the payments and benefit costs that would have been incurred by the Company if the named executive officer's employment had terminated as of the last business day of the fiscal year ended December 31, 2024. The amounts included below do not include payments and benefits to the extent they are provided on a non-discriminatory basis to salaried employees generally upon termination of employment.

  59. TERMINATION AND CHANGE OF CONTROL POTENTIAL PAYMENTS AND BENEFITS TABLE

    (1) See above in “Potential Payments Upon Termination or Change in Control” for the definition of "good reason" under the employment agreements with our NEOs. (2) Under the Severance Policy, the NEOs are entitled to accelerated equity award vesting if their employment is terminated or they resign for good reason within 18 months of a change of control. (3) For Cash Severance, amount represents the payment of an amount equal to 12 months of the employee’s annual base salary, as well as (i) for involuntary termination without cause or resignation for good reason not in connection with a change of control, a lump sum payment of the pro rata portion of the executive’s annual bonus for the year of termination or resignation based actual performance (a “Performance Bonus”), and (ii) for involuntary termination without cause or resignation with good reason in connection with a change of control, a Performance Bonus and a lump sum payment in an amount equal to the executive’s target annual bonus for the year of termination or resignation (a “Target Bonus”). For Health and Welfare, amount represents the estimated value of providing the employee and their dependents with health benefits for 12 months following the date of termination or resignation for good reason. This amount is calculated based on the current market rate of COBRA premiums in California. (4) For Cash Severance, amount represents the payment of an amount equal to 18 months of the employee’s annual base salary, as well as (i) for involuntary termination without cause or resignation for good reason not in connection with a change of control, a Performance Bonus, and (ii) for involuntary termination without cause or resignation with good reason in connection with a change of control, a Performance Bonus and a Target Bonus. For Health and Welfare, amount represents the estimated value of providing the employee and their dependents with health benefits for 18 months following the date of termination or resignation for good reason. This amount is calculated based on the current market rate of COBRA premiums in California. (5) For Equity Treatment, amount represents the estimated value of accelerated vesting of stock options subject to outstanding stock options upon a termination or resignation for good reason prior to December 31, 2024.

  60. CEO PAY RATIO

    CEO PAY RATIO For 2024, Mr. Payne’s total annual compensation as disclosed in the Summary Compensation Table was $3,697,000, and the total annual compensation for our median employee was $269,150, resulting in a pay ratio of 13.7 (the “Pay Ratio”). To identify the median employee and calculate the annual total compensation of the median-paid employee, we determined (i) the total number of part-time and full-time individuals employed at any point during fiscal year 2024, and (ii) the sum of the salary, bonus, and share-based compensation incurred for each employee. We believe the pay ratio reported above is a reasonable estimate calculated in a manner consistent with SEC rules based on our internal records and the methodology described above. Because the SEC rules for identifying the median compensated employee and calculating pay ratio allow companies to adopt a variety of methodologies, apply certain exclusions, and make reasonable estimates and assumptions that reflect their employee populations and compensation practices, our pay ratio may not be comparable to the pay ratios reported by other companies.

  61. Pay Versus Performance Disclosure

    Pay Versus Performance Disclosure In accordance with rules adopted by the Securities and Exchange Commission pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, we provide the following disclosure regarding executive compensation for our principal executive officer (“PEO”) and Non-PEO NEOs and Company performance for the fiscal years listed below.
