#### WESCO Distribution, Inc.

#### Retirement Savings Plan

#### Notes to Financial Statements
The Company matches contributions made by employees into the Plan at an amount equal to 100% of a participant's eligible elective deferrals up to 3% of the participant's eligible compensation and 50% of the next 4% of eligible compensation. The Company performs a true-up calculation at the end of each plan year so that the full employer matching contribution is made for all participants of the Plan. Any necessary additional matching contribution is made in the subsequent year. The true-up contributions for the years ended December 31, 2024 and 2023 were approximately $3.1 million and $3.9 million, respectively, and are recorded as employer contributions receivable in the accompanying Statements of Net Assets Available for Benefits.

Participants may rollover into the Plan amounts representing distributions from other qualified retirement plans, an individual retirement account or an annuity. For the years ended December 31, 2024 and 2023, the Plan accepted employee rollover contributions of approximately $14.6 million and $28.2 million, respectively. Of the $28.2 million employee rollover contributions for the year ended December 31, 2023, approximately $17.2 million relates to employee rollovers from the Anixter Inc. Pension Plan, which has been terminated.

In 2024, excess plan assets of $8.9 million from the termination of the Anixter Inc. Pension Plan were transferred to the Plan as a transfer to a qualified replacement plan. The transfer was used to fund certain of the Company’s matching contributions to the Plan during 2024 and is included in employer contributions in the accompanying Statement of Changes in Net Assets Available for Benefits.

Under the Plan's annual increase program, participant contributions automatically increase at a rate of 1% annually each April 1 until the deferral rate equals 7%. Participants may opt-out of automatic annual increases, elect to continue automatic deferral rate increases after reaching the
