Exhibit 99.1

Slide Announces New Stock Repurchase Program of $125 Million

TAMPA, Fla., March 23, 2026 – Slide Insurance Holdings, Inc. (“Slide” or the “Company”) (Nasdaq: SLDE) today announced that it has completed its initial $120 million common stock repurchase program and that its Board of Directors has authorized a new common stock repurchase program of $125 million. The authorization is effective immediately, has no time limit, and may be modified, suspended or discontinued at any time.

“We are pleased that the Board has authorized a new $125 million stock repurchase program, reflecting confidence in our long-term growth strategy, superior underwriting capabilities and robust capital position,” said Bruce Lucas, Chairman and Chief Executive Officer of Slide. “Given the abundant capital we maintain to successfully execute on our diversified growth strategy and the ability of our business model to generate significant free cash flow, we will opportunistically repurchase common stock when we believe it is below fair value and further create long-term value for our shareholders. At current levels, we believe it is very accretive for Slide to repurchase common stock.”

Under the prior completed program, Slide repurchased 7,109,417 common shares at a weighted average share price of $16.88.

Share repurchases under the stock repurchase program may be made in the open market at prevailing market prices, through privately negotiated transactions, or through other structures in accordance with applicable federal securities laws, at times and in amounts as management deems appropriate. The timing and the amount of any common stock repurchases will be determined by the Company’s management based on its evaluation of market conditions, the company’s liquidity needs, corporate and regulatory requirements and restrictions, share price, trading volume and other factors. Repurchases of common stock may be made under a Rule 10b5-1 plan, which would permit common stock to be repurchased when the company might otherwise be precluded from doing so under insider trading laws. The repurchase program does not obligate the company to purchase any particular number of shares and may be suspended, modified, or discontinued at any time without prior notice.
