FAQ

What insider transaction did Solstice (SOLS) director Lee Rose report?

Lee Rose reported receiving two small RSU grants of 2 units each. These restricted stock units are equity-based compensation, not open-market share purchases or sales, and each RSU converts into one share of Solstice Advanced Materials Inc. common stock when it vests.

How many Solstice (SOLS) restricted stock units does Lee Rose now hold?

After the reported grants, Lee Rose holds 2,476 RSUs. These units represent future rights to receive an equal number of Solstice common shares once vesting conditions are met, supplementing Rose’s existing common stock position disclosed in the same Form 4 filing.

When do Lee Rose’s new Solstice (SOLS) RSUs vest?

The new RSUs vest on two different schedules. One set of restricted stock units will vest on the date of Solstice’s next annual meeting of shareowners, while another set is scheduled to vest on April 15, 2026, subject to continued service conditions.

What are dividend equivalent RSUs mentioned in the Solstice (SOLS) filing?

Dividend equivalent RSUs accrue in connection with Solstice’s dividend. They give Lee Rose additional RSUs that mirror cash dividends, and these units vest at the same times as the underlying RSUs, effectively reinvesting dividend value into additional stock units rather than cash payments.

How did Lee Rose acquire 368 Solstice (SOLS) common shares?

The 368 Solstice common shares came from the Honeywell spin-off. The filing notes these shares were received in connection with the separation of Solstice Advanced Materials Inc. from Honeywell International Inc., rather than through market purchases or sales by the director.
