STOCK-BASED COMPENSATION
On November 30, 2017, the Company’s stockholders approved the adoption of the 2017 Employee, Director and Consultant Equity Incentive Plan (as amended, the “2017 Plan”). The 2017 Plan allows the Company, under the direction of the Compensation and Human Capital Committee (the "CHCC") of the Board of Directors, to make grants of restricted and unrestricted stock and stock unit awards to employees, consultants and directors. Stockholders have subsequently approved amendments to the 2017 Plan increasing the shares available to grant thereunder, including most recently at the Company's annual meeting of stockholders held on June 5, 2025, when stockholders approved an amendment to the 2017 Plan to increase the aggregate number of shares of common stock available thereunder for the granting of awards by an additional 6.5 million shares. As of December 31, 2025, the Company had 5.3 million shares of common stock available for grant under the 2017 Plan. If an RSU awarded under the 2017 Plan is cancelled or forfeited without the issuance of shares of common stock, the unissued shares that were subject to the RSU will again be available for issuance pursuant to the 2017 Plan.
The number of shares, terms, and vesting periods are generally determined by the Company’s Board of Directors or the CHCC on an award-by-award basis. RSUs granted to employees generally vest either ratably over three or four years or as cliff vesting after three years either on the anniversary of the date on which the RSUs were granted or during the month in which such anniversary dates occur. The number of PSUs awarded to certain employees may be increased or reduced based on certain additional performance and market metrics. RSUs granted to non-employee directors generally vest in full upon the earlier of the completion of one year of service following the date of the grant or the date of the next annual meeting of stockholders following such grant.
The performance and market conditions associated with PSU awards granted during the year ended December 31, 2025 include vesting that is based on revenue targets (34% weighting), adjusted earnings per share targets (33% weighting), and relative total stockholder return (33% weighting) measured against the Nasdaq Health Care Index (IXHC) using the 20-trading day averages at the beginning and end of the measurement period. The measurement period for the relative total stockholder return metric is January 1, 2025 through December 31, 2027, and the revenue and adjusted earnings per share metrics will be measured based on fiscal year 2027 results. The Company estimates the likelihood of achievement of performance conditions for all PSU awards at the end of each period. To the extent those awards or portions thereof are considered probable of being achieved, such awards or portions thereof are expensed over the performance period. The portion of the awards pertaining to relative total stockholder return represent market conditions and, accordingly, the estimated fair value of such awards is recognized over the performance period.
During the year ended December 31, 2025, the Company granted stock-based awards to the Company's new Chief Commercial Officer as an inducement material to his commencement of employment and entry into an employment agreement with the Company. The inducement awards were made in accordance with Nasdaq Stock Market rules and were not made under the 2017 Plan. The inducement awards are included in the tables below.

Employee Stock Purchase Plan
The Company also has an Employee Stock Purchase Plan that was initially approved by stockholders in 2012 and was amended and approved by the Board of Directors of the Company on September 23, 2021 and the stockholders on June 2, 2022 (the “Amended and Restated 2012 Purchase Plan”), under which 4.0 million shares of common stock were authorized for issuance. Shares are issued under the Amended and Restated 2012 Purchase Plan twice yearly at the end of each offering period and the number of shares that may be purchased by any participant during an offering period is limited to 5,000 shares. The first offering period of 2025 started on December 1, 2024 and ended on May 31, 2025. The second offering period of 2025 began on June 1, 2025 and ended on November 30, 2025. As of December 31, 2025, no shares of common stock were available for issuance under the Amended and Restated 2012 Purchase Plan. Shares purchased under, and compensation expense associated with, the Amended and Restated 2012 Purchase Plan for the periods reported are as follows:

The fair value of shares issued under the Amended and Restated 2012 Purchase Plan that was in effect for each period reported was calculated using the Black‑Scholes option-pricing model using the weighted-average assumptions below. Each of these inputs is subjective and its determination generally requires significant judgment.

About Stock Compensation Disclosures

Stock-based compensation disclosures detail the equity awards granted to employees and executives — including stock options, restricted stock units (RSUs), and performance shares — along with the valuation methods and assumptions used to expense them. This section reveals the true cost of talent retention and the alignment between management incentives and shareholder interests.

Key signals: total unrecognized compensation expense and its expected recognition period signal future earnings headwinds from already-granted awards. For stock options, examine Black-Scholes assumptions — expected volatility, risk-free rate, and expected term — as understating any of these reduces reported compensation expense. Compare stock compensation expense as a percentage of revenue against peers to assess dilution cost. Watch vesting schedules for acceleration clauses tied to change-of-control events. Performance-based awards with undemanding targets may indicate weak governance. Add back stock compensation to operating cash flow to calculate a more conservative free cash flow figure.
