(the “Company”) was incorporated in the state of Delaware on March 18, 2008 and is headquartered in Santa Clara, California. The Company is a medical device company that has pioneered a proprietary minimally invasive surgical implant system to fuse the sacroiliac joint for treatment of the most common types of sacroiliac joint disorders that cause lower back pain. The Company introduced its primary product, the iFuse Implant System, or iFuse, in 2009 in the U.S., in 2010 in certain countries in the European Union, and in 2015 in certain countries in the rest of the world.</font></div><div style="line-height:120%;padding-top:12px;text-align:left;padding-left:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Reverse Stock Split</font></div><div style="line-height:120%;padding-top:12px;text-align:justify;text-indent:33px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In October 2018, the Company's board of directors and stockholders approved a 1-for-18 reverse stock split of the Company's common stock and redeemable convertible preferred stock, which was effected on October 4, 2018. The par value of the common stock and redeemable convertible preferred stock was not adjusted as a result of the reverse split. All issued and outstanding share and per share amounts of common stock, redeemable convertible preferred stock, stock options, and warrants included in the accompanying consolidated financial statements have been adjusted to reflect this reverse stock split for all periods presented.</font></div><div style="line-height:120%;padding-top:12px;text-align:left;padding-left:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Initial Public Offering </font></div><div style="line-height:120%;padding-top:8px;text-align:justify;text-indent:33px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">On October 16, 2018, the Company’s Registration Statement on Form S-1 (File No. 333-227445) relating to the initial public offering ("IPO") of its common stock was declared effective by the Securities and Exchange Commission ("SEC"). Pursuant to such Registration Statement, the Company sold </font><font style="font-family:inherit;font-size:10pt;">8,280,000</font><font style="font-family:inherit;font-size:10pt;"> shares at an initial public offering price of </font><font style="font-family:inherit;font-size:10pt;">$15.00</font><font style="font-family:inherit;font-size:10pt;"> per share for net proceeds of </font><font style="font-family:inherit;font-size:10pt;">$113.4 million</font><font style="font-family:inherit;font-size:10pt;"> to the Company, net of underwriting discounts and commissions and offering costs.

Significant accounting estimates and management judgments reflected in the consolidated financial statements include: fair value of assets and liabilities; analysis of the allowance for doubtful accounts; inventory valuation; valuation of deferred tax assets, including related valuation allowances; fair value of common stock and redeemable convertible preferred stock warrants; stock-based compensation; and useful lives of long-lived assets. Estimates are based on historical experience, where applicable and other assumptions believed to be reasonable by the management. Actual results could differ from those estimates.</font></div></div>
