  5. Executive Compensation Philosophy and Objectives

    | • | compensation programs should motivate executives to manage our business to meet our short- and long-term objectives by rewarding them for meeting those objectives. |

  6. Compensation Practices Summary

    | What We Do | | | ✔ | Total compensation is evaluated against competitive market data as defined by a peer group that is evaluated and adjusted annually and relevant industry-specific and size-appropriate survey data. | | ✔ | Tie majority of compensation to Company performance and creation of long-term value for our shareholders. | | ✔ | We evaluate corporate performance in our annual incentive plan. Performance is compared to our corporate objectives as described under the heading “—Annual Incentive Compensation and Bonuses.” | | ✔ | We allocate our compensation among base salary and short- and long-term incentive compensation target opportunities in such a way as to not encourage excessive risk-taking inclusive of caps on the maximum levels of payout, use of a variety of performance metrics and board approval of the compensation structure. | | ✔ | We apply Company-wide metrics to encourage decision-making that is in the best long-term interests of the Company and our shareholders. | | ✔ | We use a mix of equity award instruments under our long-term incentive program, including both share options and full-value restricted stock units. | | ✔ | Our equity awards vest over multi-year periods. | | ✔ | Our long-term incentive awards require both a change in control and a qualifying termination of employment (a so-called “double-trigger”) to trigger vesting following a change in control. | | ✔ | The compensation committee retains an independent compensation consultant to advise on market practices and specific compensation programs. | | ✔ | We conduct an annual advisory say-on-pay vote and actively review the results as we make program decisions. We solicit feedback regarding our compensation programs from shareholders and proxy advisers and consider any other shareholders comments we receive. | | ✔ | We maintain a clawback policy as described under the heading “Clawback Policy.” | | What We Don’t Do | | | ✘ | We do not provide single-trigger vesting of employee equity awards upon a change in control. | | ✘ | We do not provide tax gross-ups for NEOs to cover excise taxes under Section 4999 of the Internal Revenue Code. | | ✘ | We strictly prohibit officers and directors from engaging in short selling, put, call, or other derivative transactions or hedging or other monetization transactions, including through the use of financial instruments such as prepaid variable forwards, equity swaps, collars and exchange funds, in our common stock. | | ✘ | We do not pay dividends or dividend equivalents on shares or units that are not vested. | | ✘ | No pension benefits provided to NEOs or significant perquisites. |

  7. 2025 Executive Compensation

    | • | We awarded annual cash incentive awards, as discussed in “Annual Incentive Compensation and Bonuses”; and |

  8. 2025 Executive Compensation

    | • | We awarded long-term incentive awards, as discussed in “—Long-Term Incentives—Equity Compensation.” |

  9. Compensation Components

    Compensation Components The three primary components of executive compensation are base salary, annual incentive cash bonus and long-term equity incentive awards. These components are administered with the goal of providing total compensation that is competitive in the marketplace, while recognizing meaningful differences in individual performance and offering the opportunity to earn greater incremental rewards when merited by individual and Company performance. Base Salary. We pay our NEOs a base salary, which our compensation committee reviews and determines annually. Base salaries are used to compensate our NEOs for performing the core responsibilities of their positions and to provide them with a level of security with respect to a portion of their total compensation. Base salaries are set in part based on the NEO’s unique skills, experience and expected contribution to the Company, as well as individual performance, including the impact of such performance on our business results and the length of the NEO’s service at the Company. Decisions regarding base salary increases take into account the NEO’s current base salary, third-party benchmark and survey data, the salary compensation paid to other executive officers within the Company, our overall performance and its success in achieving its operational and strategic goals and objectives, the NEO’s contribution to Company performance and, for our non-CEO NEOs, recommendations made by our CEO. Annual Incentive Cash Bonus. Annual incentive compensation is intended to establish a direct correlation between annual cash awards and our performance. Our Annual Incentive Plan, or “AIP,” is an annual incentive cash bonus plan designed to align the interests of participants with the interests of the Company and our shareholders. The AIP is designed to strengthen the link between a participant’s pay and his or her overall performance and our performance, focus participants on critical corporate objectives, offer a competitive cash incentive and encourage and reward performance and competencies critical to our success. Each NEO is given a target amount under the AIP that is calibrated competitively to our market benchmarks (see more detailed discussion on market benchmarks below). Long-Term Incentive Compensation. In addition to using base salaries and annual incentive cash bonuses, which our compensation committee views as short-term compensation to reward our NEOs for meeting Company performance objectives, a significant portion of our NEOs’ compensation is in the form of long-term equity incentive awards. Our long-term incentive compensation serves to align a significant portion of each executive’s total compensation with our long-term performance and the interests of our shareholders. To that end, each year the compensation committee provides an annual equity-based incentive award to each of our NEOs that is typically composed of restricted share units (“RSUs”). To responsibly manage our share pool and minimize potential dilution to stockholders, the annual equity awards for the past three years were granted entirely in the form of RSUs, other than new hire awards that were granted in the form of stock options. RSUs are linked to stock price performance but expend fewer shares than stock options to deliver the same value. Granting in RSUs allows us to effectively manage our annual share usage while continuing to provide the necessary incentives that continue to drive shareholder alignment. We intend to annually revisit our long-term incentive program to determine which vehicles strike the right balance between shareholder alignment, engagement and performance. The annual equity awards are designed to engage Company leaders to focus on our long-term performance, offer participants competitive and market-based long-term incentive award opportunities and strengthen the link between a participant’s compensation, his or her overall performance and the Company’s performance. We believe that the annual equity awards will further assist us in achieving an appropriate balance between our long- and short-term performance, as well as between the achievement of annual operating objectives and creating long-term value and the delivery of shareholder return by providing compensation commensurate with overall Company performance. For more information regarding our equity compensation plans, please see “—Long-Term Incentives—Equity Compensation.”

  10. Setting Executive Pay (Benchmarking)

    Setting Executive Pay (Benchmarking) Our compensation committee retained an independent compensation advisor to conduct a competitive benchmarking analysis for compensation decisions. As an initial step in that process, our consultant reviewed the prior year’s criteria and, based on changes in our headcount, revenue and market capitalization, recommended changes for determining a peer group of companies. At the compensation committee’s request, our independent compensation advisor reviewed the criteria in September 2024 for use in benchmarking to inform Q1 2025 compensation decisions. Based on our then-current revenue, headcount and market capitalization profile, Pearl Meyer recommended the following criteria to assess the peer group:

  11. Setting Executive Pay (Benchmarking)

    | • | Public, emerging commercial bio pharma companies with a preference for companies in US biotech “hub” locations and those focused in oncology; |

  12. Setting Executive Pay (Benchmarking)

    | • | Market capitalization generally between $100 million and $1 billion; |

  13. Setting Executive Pay (Benchmarking)

    | • | Annual revenue between $50 million and $250 million; and |

  14. Setting Executive Pay (Benchmarking)

    | • | 125 to 500 employees. |

  15. Setting Executive Pay (Benchmarking)

    Former peers that no longer met the above criteria or were otherwise considered a poor business comparator based on the Company’s current size and profile were replaced with more appropriate go-forward comparators. Based on the criteria set forth above, the final group of peer companies approved by our compensation committee in September 2024 for use in benchmarking to inform Q1 2025 compensation decisions was composed of the following companies:

  16. Setting Executive Pay (Benchmarking)

    | • 2seventy bio, Inc. (acquired by Bristol Myers Squibb) • Heron Therapeutics [HRTX] • Pyxis Oncology, Inc. [PYXS] • Adaptimmune Therapeutics plc • Immunome, Inc. [IMNM] • Rigel Pharmaceuticals [RIGL] • Akebia Therapeutics, Inc. [AKBA] • KaryoPharm Therapeutics Inc. [KPTI] • uniQure N.V. [QURE] • Allogene Therapeutics, Inc. [ALLO] | • Urogen Pharma Ltd. [URGN] • Aquestive Therapeutics, Inc. [AQST] • Mersana Therapeutics, Inc. (acquired by Day One Biopharmaceuticals) • X4 Pharmaceuticals [XFOR] • Esperion Therapeutics, Inc. [ESPR] • Nektar Therapeutics [NKTR] • Y-mAbs Therapeutics (acquired by SERB Pharmaceuticals) • Fate Therapeutics, Inc. [FATE] • Puma Biotechnology, Inc. [PBYI] |

  17. Setting Executive Pay (Benchmarking)

    | • MacroGenics [MGNX] | • Zymeworks Inc. [ZYME] |

  18. Setting Executive Pay (Benchmarking)

    Based on our compensation objectives and philosophy and the information provided by our independent compensation advisor, the compensation committee determined that overall compensation for our executive officers is aligned with market practice. The compensation committee does not have a specific target compensation level for the NEOs; rather, the compensation committee reviews a range of market data reference points (generally at the 25th, 50th and 75th percentiles of the market data) with respect to target total direct compensation, target total cash compensation (including both base salary and the target annual cash incentive) and equity compensation. In making compensation determinations, the compensation committee considers peer group data, general market data, and any other factors the compensation committee deems appropriate.

  19. Annual Incentive Compensation and Bonuses

    Annual Incentive Compensation and Bonuses The performance goals of the AIP vary year to year, as approved by the compensation committee and our Board. The CEO proposes goals which are reviewed with the compensation committee and then the Board. The compensation committee and the Board provide comments which are incorporated into the goals. The compensation committee and Board determine the final weighting of each goal. The final version of the goals are then presented to the compensation committee and the Board for approval. Metrics are selected with a focus on a demonstrable link to long-term valuation creation and the growth of the Company. Goals are calibrated to be sufficiently robust and build on prior year accomplishments and our pipeline. Our principal objective in providing annual incentive compensation and bonuses is to reward strong Company performance. While we target our opportunities for annual incentive compensation to be market competitive, this guideline is based on target award levels and actual payouts to the NEOs, including our CEO can vary significantly based on actual performance. We set target award levels for our executives based on a percentage of their base salary, as reflected in each NEO’s employment agreement or as otherwise determined by the compensation committee. For Mr. Mallik, the target annual incentive award was 60% of base salary, and for Mr. Carmona and Dr. Zaki, their target annual incentive awards were 50% of base salary. The compensation committee and Board reviewed and approved the Company performance goals for the NEOs at its February 2025 meeting. In setting the goals for 2025, the compensation committee determined the weight that any particular Company performance goal carried within the applicable category. For the CEO and all other NEOs, the achievement of the foregoing Company performance goals account for 100% of their annual incentive compensation. Payout is capped at 150% of target for Company performance goals. With respect to the 2025 AIP, our compensation committee had discretion to increase or reduce any payment amount, including down to zero, that would otherwise be earned or payable to any executive and to take into account assessment of any other additional factors. The following table sets forth our 2025 corporate performance goals, the relative weighting of each goal and the year-end results.

  20. Annual Incentive Compensation and Bonuses

    | Performance Goals | Weighting | Actual | | Achieved | | Zynlonta Revenue | 29% | • Achieved $73.6 million in net sales | • Above target | 43.5% | | Advance Clinical Trials | 18% | • LOTIS 7: Enrolled 40 patients by April 2025 and disclosed positive data on 41 patients in June 2025 at EHA/ICLM | • Above target | 27% | | Advance ADCT-241 to IND enabling activities | 11.5% | • ADCT-241(PSMA): IND enabling activities successfully completed by year-end | • At target | 11.5% | | Implement restructuring and re-organization plan | 11.5% | • Successfully completed restructuring plan to eliminate early research, close UK facility and focus on Zynlonta | • Above target | 16% | | Extend Cash Runway, Complete Business Development Transaction and Drive Employee Engagement | 30% | • Completed two follow-on offerings and extended expected cash runway into at least mid-2028 | • Above target | 27% | | | | • Business Development transaction not yet completed | • Below target | | | | | • Employee turnover and engagement | • Above target | | | TOTAL | | | | 125% |

  21. Annual Incentive Compensation and Bonuses

    At the February 2026 meeting, the compensation committee assessed whether and to what extent the applicable performance goals were achieved for 2025. As discussed above, the compensation committee and our board of directors determined that our performance goals were achieved at a level of 125% as a result of the accomplishments during 2025. Following their annual review, the Committee determined to not apply any additional discretion to final 2025 bonus payouts. Based on this level of achievement for 2025, Mr. Mallik received a bonus payout of $582,063, Mr. Carmona received a bonus payout of $328,255 and Dr. Zaki received a bonus payout of $431,325.

  22. Long-Term Incentives – Equity Compensation

    Long-Term Incentives – Equity Compensation We maintain the 2019 Equity Incentive Plan, the Conditional Share Capital Plan and the Inducement Plan, all of which are broad-based omnibus equity compensation programs that permit the compensation committee to award various types of equity-based awards. Following a review of the benchmark data as provided by our committee’s independent compensation adviser, the compensation committee determined the targeted number of shares to grant for our 2025 annual grant based on a review of market grant levels as measured as a percent of common shares outstanding. The targeted positioning versus market aligns our long-term incentive philosophy to norms within our industry. Grants for 2025 were issued as 100% time-vested restricted stock units. Granting in RSUs allows us to effectively manage our annual share usage while continuing to provide the necessary incentives that continue to drive shareholder alignment. We intend to annually revisit our long-term incentive program to determine which vehicles strike the right balance between shareholder alignment, engagement and performance. In February 2025, we granted 650,000 RSUs to Mr. Mallik, 240,000 RSUs to Mr. Carmona and 230,000 RSUs to Dr. Zaki under the Conditional Share Capital Plan. These RSUs vest in three equal installments on the first, second and third anniversary of the grant date. We utilize double-trigger vesting. Accordingly, unless the compensation committee determines otherwise with respect to a particular grant, to the extent a change in control of the Company occurs and the Company is not the surviving corporation (or survives only as a subsidiary of another corporation) and if the awards are assumed by, or replaced with awards with comparable terms by, the surviving corporation (or parent or subsidiary of the surviving corporation), the awards will vest or become fully exercisable, as applicable on the date that the grantee is terminated by the Company without cause or the executive terminates his or her employment with good reason if such termination is upon or within 12 months following the change in control. The compensation committee recommends and the Board approves compensation for our NEOs. The compensation committee may make off-cycle grants for newly hired or newly promoted officers, and otherwise makes other grants only in special circumstances. We strictly refrain from retroactively granting share options, RSUs or other share-based awards and avoid aligning grant timing with the disclosure of material nonpublic information about our Company. We believe that our grant practices are appropriate and minimize questions regarding timing of grants in anticipation of material events, since grants become effective in accordance with standard grant procedures.

  26. Inducement Plan

    Inducement Plan Plan Administration. The Inducement Plan is administered by the compensation committee of our board of directors, subject to the board of directors’ discretion to administer or appoint another committee to administer it. Awards. Equity incentive awards under the Inducement Plan may be granted in the form of options, share appreciation rights, restricted shares, restricted share units, performance awards or other share-based awards but not “incentive stock options” for purposes of U.S. tax laws. Options and share appreciation rights will have an exercise price determined by the administrator but will not be less than fair market value of the underlying common shares on the date of grant. Vesting. The vesting conditions for grants under the equity incentive awards under the Inducement Plan are set forth in the applicable award documentation. Termination of Service and Change in Control. In the event of a participant’s termination of employment, the compensation committee may, in its discretion, determine the extent to which an equity incentive award may be exercised, settled, vested, paid or forfeited. In the event of our termination of a participant’s employment without Cause or a participant’s resignation for Good Reason (as defined in the Inducement Plan) upon or within 18 months following a change in control of the company (as defined in the Inducement Plan), any awards outstanding to the participant (unless otherwise provided in the award agreement) will immediately vest and settle, and options and share appreciation rights will become fully exercisable. In the event of a change in control that involves a merger, acquisition or other corporate transaction, any outstanding award not assumed, substituted, replaced or continued in connection with the transaction will immediately vest and settle, and options and share appreciation rights will become fully exercisable. In connection with a change of control, the compensation committee may, in its discretion, take any one or more of the following actions with respect to outstanding awards: (i) cancel any such award, in exchange for a payment in cash, securities or other property or any combination thereof with a value equal to the value of such award based on the per share value of common shares received or to be received by other shareholders in the event (or without payment of consideration if the committee determines that no amount would have been realized upon the exercise of the award or other realization of the participant’s rights); (ii) require the exercise of any outstanding option; (iii) provide for the assumption, substitution, replacement or continuation of any award by the successor or surviving corporation, along with appropriate adjustments with respect to the number and type of securities (or other consideration) of the successor or surviving corporation, subject to any replacement awards, the terms and conditions of the replacement awards (including performance targets) and the grant, exercise or purchase price per share for the replacement awards; (iv) make any other adjustments in the number and type of securities (or other consideration) subject to (a) such awards and in the terms and conditions of such awards in order to prevent the dilution or enlargement of benefits intended to be made available under the Inducement Plan and (b) awards that may be granted in the future; (v) provide that any such award shall be accelerated and become exercisable, payable and/or fully vested with respect to all shares covered thereby or (vi) provide that any award shall not vest, be exercised or become payable as a result of such event. Termination and Amendment. Unless terminated earlier, the Inducement Plan will continue for a term of ten years. Our board of directors has the authority to amend or terminate the Inducement Plan. However, no such action may impair the rights of the recipient of any options unless agreed to by the recipient.
