EXPLANATORY NOTE

​ On July 31, 2024, Glaukos Corporation (the “Company”) filed a Current Report on Form 8-K (the “Initial Report”) with the Securities and Exchange Commission (the “SEC”) to furnish its earnings press release (the “Earnings Release”), and quarterly summary (the “Quarterly Summary”), each disclosing financial results for its second quarter ended June 30, 2024. This Current Report on Form 8-K/A amends the Initial Report to correct certain financial information included in the Earnings Release and the Quarterly Summary as further described below. This Current Report on Form 8-K/A. should be read in conjunction with the Initial Report. ​ Item 2.02. Results of Operations and Financial Condition. On July 31, 2024, the Company issued the Earnings Release, a copy of which was furnished as Exhibit 99.1 to the Initial Report. On August 2, 2024, the Company filed with the SEC its Quarterly Report on Form 10-Q for its second quarter ended June 30, 2024 (its “Quarterly Report”). In preparing the final Quarterly Report, the Company, in consultation with its independent registered public accounting firm, concluded that, in connection with the exchange agreements entered into with certain holders of eighty percent of its 2.75% Convertible Senior Notes due 2027 (Exchange Transaction) that occurred in June 2024, the acceleration of approximately $3.3 million of unamortized non-cash debt issuance costs should have been accounted for as a decrease in additional paid-in capital, rather than as an interest expense, as was reflected in the Earnings Release and Quarterly Summary. In the financial statements contained in the Earnings Release and the Quarterly Summary, interest expense, total non-operating expense, loss before taxes, and net loss for the three and six months ended June 30, 2024 each were overstated by $3.3 million, basic and diluted net loss per share was overstated by $0.06 and $0.07 for the three and six months ended June 30, 2024, respectively, and additional paid-in capital and accumulated deficit were overstated by an offsetting, corresponding $3.3 million. Each of these items is correctly reported in the Company’s Quarterly Report. The revised accounting treatment did not impact the non-GAAP financial results as reported in the Earnings Release and the Quarterly Summary. ​ Financial statements reflecting the foregoing revisions to the financial information included in the Earnings Release and Quarterly Summary are attached to this Current Report on Form 8-K/A as Exhibit 99.1. The Earnings Release and Quarterly Summary have also been updated to reflect the foregoing revisions and are available on the Company’s website at investors.glaukos.com. ​ The information contained in this Item 2.02 and in the accompanying Exhibit 99.1shall not be deemed filed for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or incorporated by reference in any filing under the Exchange Act or the Sec
