Ideal Power Reports First Quarter 2017 Financial Results
Management to Host Conference Call at 4:30 p.m. ET
AUSTIN, TX – May 11, 2017 -- Ideal Power Inc. (NASDAQ: IPWR), a developer of innovative power conversion technologies, reported results for its first quarter ended March 31, 2017.
Key First Quarter 2017 and Subsequent Highlights:
Completed a $15 million private placement with institutional and accredited investors. All members of senior management and the Board of Directors participated in the private placement.
Introduced and received UL 1741 certification for SunDial™ and Stabiliti™ series 30kW power conversion systems (PCS).
Shipped next generation 30kW PCS to multiple, new potential volume customers for use in their initial projects incorporating our technology.
Strengthened patent estate: currently have 65 issued patents, including 25 issued patents for B-TRAN™ and approximately 90 patent applications pending.
"In the first quarter of 2017, we transitioned to our third generation of 30kW products, the SunDial and Stabiliti,” said Dan Brdar, Chief Executive Officer. “Because of the strong interest we have already seen in these products, we foresee revenue ramping in the second half of 2017 from existing and new customers for microgrid and solar plus storage installations.”
“We are in advanced discussions with several of these customers, with purchase orders already in hand or in hand pending the arrangement of financing,” Brdar added. “We are also continuing to make progress on a master supply agreement with NEXTracker, which we also expect will drive revenue in the second half of 2017. In addition, we believe we are well positioned to benefit from both the 2016 awards and the first phase of 2017 funding under California’s Self Generation Incentive Program (SGIP).”
“The new solicitation from the California Public Utility Commission (CPUC) of $90 million in incentives commenced on May 1, 2017, and was oversubscribed within two days. For the calendar years 2017 to 2019, the total SGIP incentive budget has been set at $567 million.”
“We have also made significant progress behind the scenes with our business development initiatives in the U.S. and abroad. More specifically, we received certification for our two new 30kW power conversion systems, expanded our

1


product capabilities with the launch of these products, began the certification process for our 30kW product for the Australian market, and shipped our new Stabiliti product to multiple new customers for their initial projects incorporating our advanced power conversion systems.”
Brdar concluded: “As we look forward to the balance of 2017, we remain confident about solidifying second-half revenue opportunities based on our progress with NEXTracker and other strategic partners, the 2016 and first phase of 2017 SGIP incentives in California, and the continued commercial rollout of our new Stabiliti and SunDial series products that address the solar plus storage, standalone storage and microgrid markets.”
First Quarter 2017 Financial Results
Q1 2017 product revenue totalled $0.3 million versus $0.5 million in Q1 2016 with the decrease in revenue primarily attributable to the timing of, and variability in, the early market for energy storage.
Q1 2017 gross margins were negative 158% compared to 0.4% gross margins in Q1 2016, primarily attributable to the non-cash write down of inventory of $349 thousand associated with our 125kW battery converter and end-of-life, first generation IBC-30 battery converter. Margins in the quarter were also negatively impacted by the launch of the SunDial and Stabiliti in the quarter due to initial low volume and thus higher cost pilot builds for these products.
Q1 2017 net loss was $3.1 million compared to $2.8 million in Q1 2016.
Q1 2017 cash used in operating and investing activities was $2.5 million compared to $2.8 million in Q1 2016.
Cash and cash equivalents totalled $15.4 million as of March 31, 2017 with no long-term debt outstanding.
"The first quarter of 2017 featured the $15 million financing that demonstrates continued shareholder confidence in and support for Ideal Power’s disruptive technologies for power conversion systems in the commercial and industrial storage market,” said Tim Burns, Chief Financial Officer. “With this additional funding, we believe our current cash position will support operations while the energy storage market develops. During the first quarter, the expected gross margin contraction from introducing new products was amplified as we recorded a non-cash write down of inventory for our legacy products. We expect gross margins to normalize later this year, particularly as we anticipate revenue ramping in the second half of 2017.”

Safe Harbor Statement
All statements in this release that are not based on historical fact are "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995 and the provisions of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements in this press release include our statements that we expect revenue to ramp in the second half of 2017 as we have seen strong interest in our Stabiliti and SunDial products from existing and new customers for microgrid and solar + storage installations, that we are well positioned to benefit from both the 2016 awards and the first phase of 2017 funding under California’s Self Generation Incentive Program (SGIP), that we remain confident about solidifying second-half revenue opportunities based upon our progress with NEXTracker, the prior year and new SGIP incentives in California, and the continued commercial rollout of our new Stabiliti and SunDial series products, that, with the additional funding from our March 2017 private placement, we believe our current cash position will support operations while the energy storage market develops and that we expect gross margins to normalize later this year, particularly as revenue ramps in the second half of 2017. While management has based any forward-looking statements included in this release on its current expectations,

the information on which such expectations were based may change. These forward-looking statements rely on a number of assumptions concerning future events and are subject to a number of risks, uncertainties and other factors, many of which are outside of our control that could cause actual results to materially differ from such statements. Such risks, uncertainties, and other factors include, but are not limited to, whether the patents for our technology provide adequate protection and whether we can be successful in maintaining, enforcing and defending our patents, the timing and impact of regulatory developments affecting the markets for our products, our inability to predict with precision or certainty the pace of development and commercialization of our advanced technologies, the uncertainty of whether the demand for energy storage products will grow at a pace consistent with our expectations, whether our backlog will translate into revenue in future periods, whether demand for our products, which we believe are disruptive, will develop, and whether we can compete successfully with other manufacturers and suppliers of power conversion products, both now and in the future, as new products are developed and marketed. Furthermore, we operate in a highly competitive and rapidly changing environment where new and unanticipated risks may arise. The availability and amount of government incentive programs affect our customers spending patterns, and adverse changes or developments in such programs - such as the SGIP in California - have materially and adversely affected our orders, net sales, gross profit and net income, and may do so again in the future. Accordingly, investors should not place any reliance on forward-looking statements as a prediction of actual results. Additional information relating to the uncertainty affecting our business are contained in our filings with the Securities and Exchange Commission. These documents are available on the SEC Filings section of the Investors section of our website at http://ir.idealpower.com/. These forward-looking statements represent our expectations as of the date of this press release. We disclaim any intention to, and undertake no obligation to, update or revise forward-looking statements.
