Operating Expenses
Selling, General and Administrative Expenses
Selling, general and administrative expenses (“SG&A”) consist primarily of costs related to our employees, independent contractors and consultants. Other significant general and administrative expenses include accounting and legal services and expenses associated with obtaining and maintaining patents as well as marketing and advertising services and expenses associated with establishing our brand and developing our website, marketing materials and call center.
For the three months ended June 30, 2022 and 2021, we incurred $4,105,066 and $1,613,608, respectively, of SG&A expenses. We attribute the increase of $2,491,458 primarily to offering costs expensed in conjunction with the private placement (approximately $1,300,000) public company costs (an increase of approximately $1,000,000) and costs related to the development of Pūrgo Lift (an increase of approximately $150,000).
For the six months ended June 30, 2022 and 2021, we incurred $6,247,290 and $1,993,610, respectively, of SG&A expenses. We attribute the increase of $4,253,680 primarily to the offering costs associated with the private placement (approximately $1,300,000) and an increase in costs required to be a public company as well as a greater level of business activities being conducted in the six months ended June 30, 2022 as compared to the same period in 2021. Public company costs include: audit and legal fees; costs required to establish investor relations, financial reporting and public relations functions; increased insurance costs; public company filing and registration fees; and related costs. These public company costs drove an increase in SG&A of approximately $1,800,000 for the six months ended June 30, 2022 as compared to the prior year period. The balance of the increase was primarily due to an increase in stock-based compensation expense of approximately $500,000 and increased rent and personnel costs of approximately $550,000.
Research and Development Expenses
Since our inception, we have focused our resources on our research and development activities. We expense research and development costs as they are incurred. Our research and development expenses primarily consist of outsourced engineering, product development and manufacturing design costs. For the three months ended June 30, 2022 and 2021, we incurred $579,061 and $1,070,912 respectively, in research and development costs. For the six months ended June 30, 2022 and 2021, we incurred $1,110,544 and $2,660,602 respectively, in research and development costs. Research and development expenses decreased by $491,851 and $1,550,058 for the three and six months ended June 30, 2022 as compared to the prior year period. Research and development activities were higher in the second quarter and first half of 2021 as compared to the current quarter and first half of 2022 due to product development, engineering, testing and regulatory costs incurred to prepare our Pūrgo device for launch in July 2021.
Change in Fair Value of Warrant Liability
The fair value of the warrant liability was an increase of $650,000 between the initial measurement date of June 24, 2022 and June 30, 2022. The non-cash loss of $650,000 resulting from increase in the fair value of the warrant liability was reported in our statement of operations for the three and six months ended June 30, 2022.
Net Losses
Our net losses were $5,172,277 and $2,684,520 for the three months ended June 30, 2022 and 2021, respectively. Our net losses were $7,750,241 and $4,654,212 for the six months ended June 30, 2022 and 2021, respectively. Losses increased in the second quarter and first half of 2022 as compared to the second quarter and first half of 2021 for the reasons set forth above.
