If Axogen needs additional capital in the future, it may raise additional funds through public or private equity offerings, debt financings or from other sources. The sale of additional equity would result in dilution to Axogen’s shareholders. There is no assurance that Axogen will be able to secure funding on terms acceptable to it, or at all. The increasing need for capital could also make it more difficult to obtain funding through either equity or debt. Should additional capital not become available to Axogen as needed, Axogen may be required to take certain actions, such as slowing sales and marketing expansion, delaying regulatory approvals or reducing headcount.
The Company’s principal sources and uses of funds are explained below:
Cash used in operating activities
Operating activities for the six months ended June 30, 2019 used $14,678 of cash as compared to using $9,920 of cash for operating activities for the six months ended June 30, 2018. This increase in cash used for operating activities of approximately $4,844 was primarily attributable to higher net losses in 2019 after adjusting for higher non-cash expenses, including stock-based compensation and depreciation, as compared to 2018.
Cash provided by investing activities
Investing activities for the six months ended June 30, 2019 provided $12,764 of cash as compared to using $914 of cash for the six months ended June 30, 2018. This increase in cash provided by investing activities was principally attributable to the redemption of short-term investments, partially offset by ongoing investment in the renovation of the APC in Vandalia Ohio.
Cash provided by financing activities
Financing activities for the six months ended June 30, 2019 provided $2,498 of cash as compared to providing $107,889 of cash for the six months ended June 30, 2018. The decrease in cash provided by financing activities was primarily the result of the net proceeds of $132,706 from the public stock offering, offset by 26,728 of payments on the Company’s debt, including prepayment fees in the prior year period. Proceeds from the exercise of stock options provided $2,515 and $1,911 of cash for the six months ended June 30, 2019 and 2018, respectively.
Operating Cash Requirements
On July 9, 2019, Axogen entered into a Standard Form of Agreement Between Owner and Design-Builder (the “Design-Build Agreement”) with CRB Builders, L.L.C., a Missouri limited liability company (“CRB”), pursuant to which CRB will renovate and retrofit the APC (See Footnote 12 Commitment and Contingencies in the Notes to the Condensed Financial Statements). The Company anticipates spending up to approximately $33,500 for renovations, equipment and furniture over the next twelve months and up to $37,600 over the next 18 months.
As previously disclosed the Company previously entered into an agreement with Heights Union, LLC, a Florida limited liability company (“Heights Union”), for the lease of seventy-five thousand square feet of office space. Pursuant to the Heights Union lease, the Company will use the Heights Union Premises for general office, medical laboratory, training and meeting purposes. The Company anticipates occupying the premises by the second quarter of 2020. Associated with the lease, the Company anticipates spending up to $12,000 for leasehold improvements, equipment and furniture and fixtures over the next twelve months.
As of June 30, 2019, we had cash, cash equivalents and investments totaling $109,063 million and total current liabilities of $16,233. Based on current estimates, we believe that our existing cash, cash equivalents and investments will allow us to fund our operations through at least the next 12 months.
Credit Facilities
On October 25, 2016, the Company entered into Term Loan and a Revolving Loan with MidCap Financial Trust (“MidCap”) maturing on May 1, 2021.
