Named Executive Officers, Footnote The PEO (CEO) for all reporting years is Marcio Souza. The non-PEO NEOs in the 2025, 2024 and 2023 reporting years are Timothy Kelly and Alex Nemiroff. The non-PEO NEOs in the 2022 reporting year are Timothy Kelly, Nicole Sweeny and Bernard Ravina. The non-PEO NEOs in the 2021 reporting year are Nicole Sweeny and Bernard Ravina.        
Peer Group Issuers, Footnote Peer Group Total Shareholder Return represents the cumulative return on a fixed investment of $100 in the Nasdaq Biotechnology (Total Return) Index (“XNBI”) for the period beginning on the last trading day of fiscal year 2020 through the end of the applicable fiscal year, assuming reinvestment of dividends. The peer group index was updated from the S&P Biotechnology Select Industry Total Return Index (“SPSIBITR”) to better reflect our industry alignment. In comparison, the value of the $100 invested in the S&P Biotechnology Select Industry Total Return Index would be the following: 2025: $87.80; 2024: $64.57; 2023: $63.82; 2022: $59.22; 2021: $79.62.

Adjustment To PEO Compensation, Footnote CAP has been calculated based on the requirements and methodology set forth in the applicable SEC rules (Item 402(v) of Regulation S-K). The CAP calculation includes the end-of-year value of awards granted within the fiscal year, the change in fair value from prior year end of vested awards and the change in the fair value of unvested awards granted in prior years, regardless of if, when, or at which intrinsic value they will actually vest. To calculate CAP for 2025, the following amounts were deducted from and added to the total compensation number shown in the SCT:

(4)The fair value of stock options reported for CAP purposes is estimated using a Black-Scholes option pricing model for the purposes of this PVP calculation in accordance with FASB ASC Topic 718 and SEC rules. This model uses both historical data and current market data to estimate the fair value of options and requires several assumptions. The assumptions used in estimating fair value for awards outstanding during 2025 are as follows:
2025
Volatility
78.01% - 106.04%
Expected life (in years)
0.5 - 8.0 years
Expected dividend yield0.00%
Risk-free rate

Additional 402(v) Disclosure
In accordance with the SEC’s disclosure requirements regarding pay versus performance (“PVP”) this section presents the SEC-defined Compensation Actually Paid (“CAP”). Also required by the SEC, this section compares CAP to various measures used to gauge performance at Praxis.
Compensation decisions at Praxis are made independently of disclosure requirements. CAP is a supplemental measure to be viewed alongside performance measures as an addition to the philosophy and strategy of compensation-setting discussed elsewhere in the overview of the executive compensation program, not in replacement.
Pay versus Performance Table - Compensation Definitions
Salary, Bonus, Non-Equity Incentive Plan Compensation, and All Other Compensation are each calculated in the same manner for purposes of both CAP and Summary Compensation Table (“SCT”) values. The primary difference between the calculation of CAP and SCT total compensation is “Stock Awards” and “Option Awards.”
SCT TotalCAP
Stock and Option AwardsGrant date fair value of stock and option awards granted during the yearChange in the fair value of stock and option awards that are unvested as of the end of the year, or vested or were forfeited during the year, as compared to the value of such awards as of the end of the prior year
Amounts reflect SCT total pay for our NEOs for each corresponding year.Total Shareholder Return (“TSR”) represents the cumulative return on a fixed investment of $100 in the Company’s common stock, for the period beginning on the last trading day of fiscal year 2020 through the end of the applicable fiscal year, assuming reinvestment of dividends.Values shown are in millions.The Company does not use any financial performance measures in setting or determining the compensation of its PEO or NEOs.
The graphs below reflect the relationship between the PEO and Average Non-PEO NEO CAP and the Company’s cumulative indexed TSR, as well as the relationship between our TSR and the TSR of our Peer Group for the fiscal years ended December 31, 2021, 2022, 2023, 2024 and 2025:
We do not currently use any financial performance measures to link executive compensation actually paid to our performance and therefore, no tabular list is reported. The metrics that we use for incentive awards instead focus on clinical, research and development and general business-related objectives.
