Rule 144 regulatory

"See the definition of "person" in paragraph (a) of Rule 144."

Rule 144 is a U.S. securities regulation that sets conditions under which restricted or insider-held shares can be legally resold to the public, such as required holding periods, availability of public information, limits on how much can be sold at once, and certain filing requirements. For investors it matters because it determines when previously locked-up shares can enter the market — like a release valve that can increase supply, affect share price, and signal insider intent.

"Common Stock | 02/21/2019 | Performance-based restricted stock unit vesting"

net exercise financial

"Common Stock | 05/01/2020 | Employee stock option exercise | ... | Net exercise"

A net exercise is a way to convert stock options into shares without paying cash up front: instead of handing over money to buy the optioned shares, the holder receives only the number of shares equal to the option’s value after the company withholds a portion of shares to cover the exercise price and taxes. It matters to investors because it changes how many new shares are issued, affects dilution of existing shareholders, and alters company cash flow compared with a cash exercise.

Attorney-in-Fact regulatory

"Signature | Corinne Lawson, as Attorney-in-Fact for Christophe Beck"

An attorney-in-fact is the person or entity given legal authority through a power of attorney to act on behalf of another for specific tasks, such as signing documents, voting shares, or handling transactions. For investors, this matters because it lets a trusted representative make timely decisions or complete paperwork when the owner cannot, much like handing keys to someone to run errands on your behalf—so checks on scope and limits of that authority are important.

FAQ

AI-generated questions and answers. How Rhea-AI works. Not financial advice.

What does the Form 144 filed for ECOL (Ecolab Inc.) by Christophe Beck mean?

The Form 144 for ECOL is a notice that officer Christophe Beck may sell Ecolab common stock under Rule 144. It discloses his intent to resell shares obtained through prior equity compensation, but it does not guarantee that any actual sales will occur.

Whose shares are covered by the ECOL Form 144 filing?

The filing covers shares held for the account of Christophe Beck, an officer of Ecolab Inc. It aggregates securities attributable to him under Rule 144’s definition of “person,” including shares from restricted stock unit vesting and stock option exercises.

How were the ECOL shares in this Form 144 originally acquired?

The shares tied to this ECOL Form 144 were acquired through performance-based restricted stock unit vesting in 2019 and employee stock option exercises in 2020 and 2021. These are equity compensation transactions rather than open-market purchases.

Which broker is listed for the potential ECOL stock sale in the Form 144?

The Form 144 lists U.S. Bank N.A., based in Milwaukee, as the broker for the potential sale of Ecolab common stock. Any sales under this notice are expected to be executed through that broker on the NYSE.

Does the ECOL Form 144 filing confirm that Christophe Beck has sold his shares?

No. A Form 144 is a notice of proposed sale, not proof of completed transactions. It indicates an intention to sell Ecolab shares under Rule 144’s conditions; actual sales, sizes, and prices would appear separately if executed.

What types of transactions are referenced in the ECOL Form 144 securities history?

The filing references performance-based restricted stock unit vesting, an employee stock option exercise with net exercise, and a broker-assisted cashless exercise. These describe how the insider originally acquired the shares that may now be resold under Rule 144.
