Preliminary Financial Information The preliminary financial results included in this press release are based on management’s initial analysis of operations for the fourth quarter and year ended December 31, 2025, and are subject to completion of Phathom’s financial closing procedures and audit. Actual results may differ materially from these preliminary estimates. Phathom’s independent registered public accounting firm has not audited, reviewed, examined, compiled, nor applied agreed-upon procedures with respect to the preliminary financial data.
Non-GAAP Financial Measures This press release includes financial results prepared in accordance with accounting principles generally accepted in the United States (GAAP) and also certain non-GAAP financial measures. In particular, we have provided non-GAAP operating expenses, adjusted to exclude stock-based compensation, which is substantially dependent on changes in the market price of our common stock. Non-GAAP financial measures are not an alternative for financial measures prepared in accordance with GAAP. However, we believe the presentation of non-GAAP operating expenses, when viewed in conjunction with GAAP results, provides investors with a more meaningful understanding of ongoing operating performance. In addition, this non-GAAP financial measure is among those indicators we use as a basis for evaluating performance, and planning and forecasting future periods. This non-GAAP financial measure is not intended to be considered in isolation or as a substitute for its most directly comparable GAAP financial measure. The difference between GAAP and non-GAAP operating expenses is included in the results presented above.
