Rhea-AI Filing Summary

Slide Insurance Holdings, Inc. Chief Risk Officer Matthew Paul Larson exercised stock options and sold the resulting shares in pre-planned transactions. On April 27, 2026 and April 29, 2026, he exercised options to acquire a total of 56,002 shares of common stock at an exercise price of $0.79 per share and sold the same 56,002 shares in open-market sales at weighted average prices of $18.77 and $20.02 per share.

After these transactions, the report shows no remaining common shares or related stock options from these grants held directly by Larson.

Insights

Equity compensation and insider-trading analyst

Pre-planned option exercise-and-sell by CRO, leaving no shares from these grants.

The Chief Risk Officer of Slide Insurance Holdings, Inc. exercised fully vested stock options at an exercise price of $0.79 per share and immediately sold all 56,002 resulting common shares in the open market at weighted average prices around $18.77 and $20.02.

The filing classifies this as an exercise-and-sell pattern, rather than an open-market purchase or simple sale of existing shares. A key detail is that the transactions were executed under a Rule 10b5-1 trading plan adopted on December 4, 2025, suggesting they were scheduled in advance and therefore carry less timing signal.

After these trades, the reported holdings show zero common shares and no remaining derivative position related to these options in this filing. Future company disclosures may provide broader context on the officer's overall equity exposure and any additional compensation awards beyond the grants exercised here.

Rule 10b5-1 trading plan regulatory

"Exercised and sold pursuant to a 10b5-1 trading plan adopted by the Reporting Person"

A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.

weighted average price financial

"Represents the weighted average price of the shares sold."

Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.

Stock Option (Right to Buy) financial

"security_title": "Stock Option (Right to Buy)""

derivative security financial

"transaction_code_description": "Exercise or conversion of derivative security""

A derivative security is a financial contract whose value comes from the price or performance of something else, such as a stock, bond, commodity, or market index. For investors it acts like an insurance policy or a wager: it can be used to protect against losses, lock in prices, or amplify gains and losses, so it can change a portfolio’s risk and potential return without owning the underlying asset directly.
