In December 2017, the Company adopted the Inari Medical, Inc. 401(k) Plan which allows eligible employees after one month of service to contribute pre-tax and Roth contributions to the plan, as allowed by law. The plan assets are held by Vanguard and the plan administrator is Ascensus Trust Company. Beginning in January 2021, the Company contributes a $1.00 match for every $1.00 contributed by a participating employee up to the greater of $3,000 or 4% of eligible compensation under the plan, with such Company's contributions becoming fully vested immediately. For the years ended December 31, 2022 and 2021, the Company recognized $7.5 million and $3.3 million, respectively, in matching contributions expense. During the year ended December 31, 2022, the Company recorded an out-of-period adjustment resulting in additional matching contribution expense of $0.8

million. The out-of-period adjustment was not considered material to the fiscal 2021 or fiscal 2022 annual consolidated financial statements.
