  • Strike level noted: Option exercise price of $120.69 could be above or below market at vesting, affecting realized value

Insights

TL;DR: Officer received multi-year equity grants aligning compensation with long-term shareholder interests.

The filing shows standard long-term incentive awards: restricted stock units and ten-year-dated options with five-year vesting schedules. These awards formally increase reported beneficial ownership by 4,142 shares (RSUs) and option exposure to 3,914 shares. Vesting in equal annual instalments over five years promotes retention and aligns executive pay with future company performance. The use of RSUs settled in shares means potential dilution occurs when settled; the option exercise price of $120.69 sets the strike level for potential future dilution. The disclosure is routine and complies with Section 16 reporting requirements.

TL;DR: Equity grant structure is typical for mid-to-long-term retention, with balanced RSU and option components.

The mix of 4,142 RSUs and 3,914 options provides both guaranteed equity upside (RSUs deliver shares if vested) and leveraged upside (options at $120.69). Five-year annual vesting smooths expense recognition and reduces short-term turnover risk. The option expiration of 09/02/2035 gives a 10-year exercise window, common in executive packages. All terms disclosed are explicit in the Form 4; there are no additional compensation details or performance conditions included in this filing.

Explanation of Responses:
1. Ms. Hughes was awarded 4,142 restricted stock units. Each restricted stock unit represents a contingent right to receive one share of Repligen Corporation's Common Stock. The restricted stock units vest in equal annual instalments over a five-year period beginning on the first anniversary of the grant date. The restricted stock units may be settled only by delivering shares of Repligen Corporation's Common Stock, and thus, the grant is being reported in Table 1 as allowed per SEC guidance.
2. The shares vest in equal annual instalments over a five-year period with each such vesting date occurring on the anniversary of the grant date.
