Explanatory Note

On April 26, 2017, Addus HomeCare Corporation (the “Company”) filed a Current Report on Form 8-K (the “Original Form 8-K”) with the Securities and Exchange Commission (“SEC”) to report that, on April 21, 2017, the Company notified BDO USA, LLP (“BDO”) that, upon the approval of the Audit Committee of the Board of Directors of the Company, BDO would be dismissed as the Company’s principal independent registered public accounting firm effective upon the date of filing for the Company’s Form 10-Q for the three months ended March 31, 2017. The Original Form 8-K also disclosed that the Company had engaged Ernst & Young LLP (“EY”) as its independent registered public accounting firm for the Company’s fiscal year ending December 31, 2017. This Amendment No. 1 to the Original Form 8-K (the “Amendment No. 1”) is being filed to disclose the specific date of BDO’s dismissal and to update the disclosures required by Item 304(a)(3) of Regulation S-K through that date.

On May 9, 2017, the Company filed its Quarterly Report on Form 10-Q for the three months ended March 31, 2017, and BDO’s dismissal as the Company’s independent registered public accounting firm became effective.

The reports of BDO on the audited consolidated financial statements of the Company for the years ended December 31, 2016 and 2015 did not contain any adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles.

During the years ended December 31, 2016 and 2015 and through May 9, 2017, there were no disagreements with BDO on any matter of accounting principles or practices, financial statement disclosures, or auditing scope or procedure, which disagreement(s), if not resolved to the satisfaction of BDO, would have caused it to make reference thereto in its reports on the audited consolidated financial statements of the Company for such years. During the years ended December 31, 2016 and 2015, and through May 9, 2017, there were no “reportable events” as defined under Item 304(a)(1)(v) of Regulation S-K, except for the material weakness reported on the Company’s Annual Report on Form 10-K for the year-ended December 31, 2015 and Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, June 30, and September 30 of 2016 related to (a) the segregation of duties, user access, and monitoring and review controls related to billable and non-billable transactions, (b) validating the completeness and accuracy of underlying data used in the operation of monitoring controls and (c) review of new hires, terminations and payroll changes. The material weaknesses identified in clauses (a) through (c) above were remediated during the quarter ended December 31, 2016.

Pursuant to Item 304(a)(3) of Regulation S-K, the Company provided BDO with a copy of this Amendment No. 1 prior to its filing with the SEC and requested that BDO furnish the Company with a letter addressed to the SEC stating whether or not BDO agrees with the above statements and, if not, stating the respects in which it does not agree. A copy of the letter from BDO is filed as Exhibit 16.1 hereto.
