Report of Independent Registered Public Accounting Firm

To Administrative Committee and Administrator of

The Perficient, Inc. 401(k) Employee Savings Plan

St. Louis, Missouri

Opinion on the Financial Statements

We have audited the accompanying statements of net assets available for benefits of The Perficient, Inc. 401(k) Employee Savings Plan (the “Plan”) as of December 31, 2023 and 2022, and the related statement of changes in net assets available for benefits for the year ended December 31, 2023, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2023 and 2022, and the changes in net assets available for benefits for the year ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on the Plan’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Plan in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Supplemental Information

The supplemental information contained in the Schedule of Assets (Held at End of Year) and the Schedule of Delinquent Participant Contributions as of and for the year ended December 31, 2023, has been subjected to audit procedures performed in conjunction with the audit of the Plan’s financial statements. The supplemental information is the responsibility of the Plan’s management. Our audit procedures included determining whether the supplemental information reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental information. In forming our opinion on the supplemental information, we evaluated whether the supplemental information, including its form and content, is presented in conformity with the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, the supplemental information is fairly stated, in all material respects, in relation to the financial statements as a whole.

The Perficient, Inc. 401(k) Employee Savings Plan

Notes to Financial Statements

1.    Description of Plan

    The following description of The Perficient, Inc. 401(k) Employee Savings Plan (the “Plan”) is provided for general information purposes only. Participants should refer to the Plan Document for a more complete description of the Plan’s provisions.

General

    The Plan is a defined contribution plan covering all full-time United States employees of Perficient, Inc. (the “Company”) who are age 21 years old or older, except any employee that is a non-resident alien with no U.S. source income. Employees may participate in the Plan on the first day of the month on or after they are determined to meet these conditions. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (“ERISA”).

    The Company’s current record keeper is Transamerica Retirement Services (“Transamerica”), which is a part of the Aegon group.

Contributions

    For 2023, participants could contribute from a percentage of their pre-tax or post-tax annual compensation to any of the investment funds up to a maximum of $22,500 (actual dollars), subject to the Internal Revenue Code of 1986, as amended (the “Code”). Participants who had attained age 50 years old before the end of the year were also eligible to make catch-up contributions of an additional $7,500 (actual dollars). Participants could also contribute amounts representing distributions from other qualified defined benefit or contribution plans.

    The Company made matching contributions of 50% (25% in cash and 25% in Company common stock) of the first 6% of eligible compensation deferred by the participant. The Company made matching contributions of $4.6 million in Company common stock during 2023. In the first quarter of 2024, the Company made a discretionary 2023 match true-up contribution of $0.7 million equally comprised of cash and stock, which is included within the employer contribution receivables as of December 31, 2023.

Participant Accounts

    Each participant’s account is credited with the participant’s contribution, the Company’s matching contribution, and an allocation of the Plan earnings and administrative expenses. Allocations are based on participant earnings or account balances, as defined in the Plan. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account.

Vesting

    Participants are vested immediately in their contributions plus actual earnings thereon. The Company contributions plus earnings thereon vest based on years of service as follows: 

Years of Service	Non-Forfeitable Percentage
Less than 1	0
1	33
2	66
3 or more	100

Notes Receivable from Participants

    Upon written application of a participant, the Plan may make a loan to the participant. Generally, participants may borrow no less than $1,000 and no more than the lesser of (i) 50% of the participant’s vested account balance, or (ii) $50,000.

4

The loans are secured by the balance in the participant’s account and bear interest at a rate commensurate with local rates for similar plans. Loans are amortized over a maximum of 60 months. Repayment is made through payroll deductions.

Payment of Benefits

    Participants are entitled to receive benefit payments at the normal retirement age of 59½, participant’s death or disability, in the event of termination, or if the participant reaches age 70½ while still employed. Benefits may be paid in a lump-sum distribution or installment payments.

Forfeitures

    As of December 31, 2023 and 2022, all forfeitures were utilized to offset employer contributions, in accordance with the Plan provisions. During the year ended December 31, 2023, employer contributions were reduced by forfeitures of $0.3 million, which included account balances forfeited during the year. There was an immaterial amount of unallocated forfeitures at December 31, 2023.

Participant-Directed Investments

    All assets of the Plan, with the exception of the Company contribution in stock, are participant-directed investments. Participants have the option of directing their account balance to one or more different investment options. The investment options include various mutual funds, collective trusts and Company common stock. See Note 3 for additional quantitative disclosures.

2.    Summary of Significant Accounting Policies

Basis of Accounting

    The financial statements of the Plan have been prepared on the accrual basis of accounting.

Use of Estimates

    The preparation of the accompanying financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect certain reported amounts and disclosures. Accordingly, actual results could differ from those estimates.

Investment Valuation and Income Recognition

    The Plan’s investments are reported at fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Plan’s administrative committee determines the Plan’s valuation policies utilizing information provided by the investment advisors and custodians. See Note 3 for discussion of fair value measurement.

    Purchases and sales of investments and realized gains and losses are accounted for on the trade date. Interest income is recorded as earned and dividend income is recorded on the ex-dividend date. Net appreciation includes the Plan’s gains and losses on investments bought and sold as well as held during the year.

Notes Receivable from Participants

    Participant loans are measured at the unpaid principal balance plus any accrued but unpaid interest. Related fees are recorded as administrative expenses and are expensed when they are incurred.

Payment of Benefits

    Benefits are recorded when paid.

5

Expenses

    Administrative expenses for participant-directed transactions, record-keeping fees and audit fees are paid by the Plan. Investment related expenses are included in net appreciation (depreciation) of fair value of investments.

3.    Fair Value Measurements

    Accounting standards provide the framework for measuring fair value. That framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described as follows:

•Level 1 – Quoted prices in active markets for identical assets or liabilities.

•Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

•Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques maximize the use of relevant observable inputs and minimize the use of unobservable inputs.

    The following is a description of the valuation methodologies used for assets measured at fair value. There have been no changes in the methodologies used at December 31, 2023 and 2022.

Cash and Temporary Investments

    The carrying value of cash equivalents approximates fair value as maturities are less than three months and measured at fair value using observable inputs in an active market and therefore are classified as Level 1.

Mutual Funds

    Mutual funds available for investment in the Plan are valued at the daily closing price as reported by the fund. Mutual funds held by the Plan are open-ended mutual funds that are registered with the Securities and Exchange Commission. These funds are required to publish their daily net asset value (“NAV”) and to transact at that price. The mutual funds held by the Plan are deemed to be actively traded.

Collective Trusts

    The Plan’s investment options are valued at the NAV of the units of the individual collective trust. The NAV, as provided by the trustee, is used as a practical expedient to estimate fair value. The NAV is based on the fair value of the underlying investments held by the fund less its liabilities. This practical expedient is not used when it is determined to be probable that the fund will sell the investment for an amount different than the reported NAV. The Plan’s collective trust investments may be redeemed on a daily basis. Irrespective of the underlying securities that comprise these collective funds, the funds themselves lack a formal listed market or publicly available quotes.

Common Stock

    Company common stock is valued at the closing price reported on the Nasdaq Global Select Market and is classified within Level 1 of the valuation hierarchy.

The following table sets forth by level, within the fair value hierarchy, the Plan’s assets at fair value (in thousands):

6

	As of December 31, 2023
	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total Fair Value

(a)    Certain investments that were measured at NAV per share (or its equivalent) have not been classified in the fair value hierarchy. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the line items presented in the Statements of Net Assets Available for Benefits.

Investments Measured at Fair Value Using Net Asset Value per Share

    The following table summarizes investments valued at fair value based on NAV per unit as of December 31, 2023 and 2022 (in thousands):

	Fair Value				Unfunded Commitments	Redemption Frequency	Redemption Notice Period
Investment Type	2023		2022
Collective Trusts	$	175,660	$	144,236	—	Daily	None

4.    Related Party Transactions

    During the year ended December 31, 2023, the Plan had the following transactions involving Company common stock (in thousands, except share information):

	Year Ended December 31, 2023
Shares purchased	79,770
Shares sold	67,621
Cost of shares purchased	$	5,394
Cost of shares sold	$	2,413
Net gain from shares sold	$	2,191

5.    Plan Termination

    Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants will become 100% vested in their employer contributions.

6.    Income Tax Status

    The Plan administrator has concluded that as of December 31, 2023, there are no uncertain positions taken or expected to be taken that would require recognition of a liability or disclosure in the financial statements. The Plan is subject to routine audits by taxing jurisdictions.

    The Internal Revenue Service has determined and informed the Company by an opinion letter dated June 30, 2020, that the Plan is established in accordance with applicable sections of the Code, and therefore, the Plan qualifies as tax-exempt under Section 401(a) of the Code. Although the Plan has been amended since receiving the opinion letter, the Plan administrator believes that the Plan is designed and operating in compliance with applicable Code requirements and, therefore, believes the Plan is qualified, and the related trust is tax-exempt.

7.    Risks and Uncertainties

    The Plan invests in various investment securities. Investment securities are exposed to various risks such as interest rate, market and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in values of investment securities will occur in the near term and that such changes could materially affect participants’ account balances and the amounts reported in the Statements of Net Assets Available for Benefits.

8.    Subsequent Events

    The Plan sponsor, Perficient, Inc., announced in May 2024 that it has entered into a definitive agreement to be acquired by an affiliate of BPEA Private Equity Fund VIII (“EQT Asia”) in an all cash transaction that values the Company at an enterprise value of approximately $3 billion. As of December 29, 2023 (the last trading day of 2023), the closing price for the Company’s common stock on The Nasdaq Global Select Market was $65.82 per share. Under the terms of the agreement, Perficient stockholders will receive $76.00 per share in cash for each share of common stock owned as of the closing of the transaction. The transaction is expected to close in 2024 and is subject to normal closing conditions including the approval by the Company shareholders and receipt of regulatory approval.
