Net income is expected to be between $181.0 million and $185.0 million, or diluted earnings per share between $4.10 and $4.20. This compares to net income of $67.4 million, or $1.51 per diluted share for fiscal 2026.

Non-GAAP net income is expected to be between $97.0 million and $101.0 million, or diluted earnings per share between $2.20 and $2.30. This compares to non-GAAP net income of $116.2 million, or diluted earnings per share of $2.61 for fiscal 2026.

Adjusted EBITDA is expected to be between $174.0 million and $178.0 million compared to adjusted EBITDA of $192.4 million in fiscal 2026.

Net interest income is expected to be approximately $8.0 million for GAAP purposes and $5.0 million for non-GAAP purposes.
