FAQ

What insider transactions did BY executive Nicolas Mando report on this Form 4?

Nicolas Mando reported equity compensation transactions in BY common stock. He received shares through performance-based and time-vested awards and had some shares disposed of to cover tax liabilities associated with these grants, as is common with stock-based compensation.

Did Nicolas Mando buy or sell BYLINE BANCORP (BY) shares on the open market?

The Form 4 shows grant and tax-withholding transactions, not open-market trades. Shares were awarded as compensation, and some were delivered back to cover tax obligations, rather than representing discretionary buying or selling in the market by the executive.

What types of stock awards did BY’s chief technology and operations officer receive?

The filing notes shares earned upon performance-vesting of a prior performance share grant and restricted shares that will vest over three years, subject to continued employment. These awards are typical components of long-term incentive compensation for senior executives at public companies.

Why were some BY common shares disposed of in Nicolas Mando’s Form 4?

Certain shares were disposed of to satisfy tax liabilities tied to the equity awards. The code used indicates payment of exercise price or tax obligations by delivering shares, a standard mechanism that avoids separate cash outlays while meeting required withholding obligations.

How do these Form 4 transactions affect Nicolas Mando’s ownership in BYLINE BANCORP?

Mando’s ownership reflects both newly awarded shares and shares delivered for taxes. The transactions include acquisitions through compensation and disposals for withholding, resulting in updated direct holdings, without indicating a strategic increase or reduction via market trading.

Are the reported BY stock awards to Nicolas Mando subject to vesting conditions?

Yes. Some shares were earned upon meeting performance conditions on a prior award, while other restricted shares will vest over three years, contingent on ongoing employment. These conditions align the executive’s incentives with longer-term company performance and retention.
