The words “believe,” “may,” “will,” “potentially,” “estimate,” “continue,” “anticipate,” “intend,” “could,” “would,” “project,” “plan,” “expect” and similar expressions that convey uncertainty of future events or outcomes are intended to identify forward-looking statements. Forward-looking statements may address the following subjects among others: the status of filter designs under development, the prospects for licensing filter designs upon completion of development, plans for other filter designs not currently in development, potential customers for our designs, the timing and amount of future royalty streams, the expected duration of our capital resources, our hiring plans, the impact of our designs on the mobile device market, and our business strategy. Forward-looking statements are inherently subject to risks and uncertainties which could cause actual results to differ materially from those in the forward-looking statements, including, without limitation, the following: our limited operating history (particularly as a new public company); our ability to complete designs that meet customer specifications; the ability of our customers (or their manufacturers) to fabricate our designs in commercial quantities; our dependence on a small number of customers; the ability of our designs to significantly lower costs as compared to other designs and solutions; the risk that the intense competition and rapid technological change in our industry renders our designs less useful or obsolete; our ability to find, recruit and retain the highly skilled personnel required for our design process in sufficient numbers to support our growth; our ability to manage growth; and general market, economic and business conditions. Additional factors that could cause actual results to differ materially from those anticipated by our forward-looking statements are under the captions “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our most recent Annual Report (Form 10-K) or Quarterly Report (Form 10-Q) filed with the Securities and Exchange Commission.

Resonant ® is a late-stage development company creating innovative filter designs for radio frequency (RF) front-ends for the mobile device industry.

Resonant uses fundamentally new technology called Infinite Synthesized Networks™, or ISN™, to configure and connect acoustic resonators, which are the building blocks of RF filters. Headquarters: Santa Barbara, Calif. Founded: May 2012 IPO: June 2014

Compelling Investment

Ø  Large and Rapidly Growing Market •  20B mobile device filters sold in 2014; Projected to grow to 35B by 2017

Ø  Low Cost Business Model • Licensing business model requires no inventory and low overhead

Ø  Disruptive Technology •  New method of designing RF filters can displace conventional filters and combine multiple

filters into one delivering lower costs, smaller sizes, and improved performance •  Fewer components would dramatically simplify the mobile device supply chain •  Biggest fundamental change to mobile device filter design in more than 80 years

Ø  Unique and Protected Intellectual Property •  Aggressively patenting key elements of the ISN™ system •  More than 70 patents (pending or issued) and growing rapidly

Ø  Significant Barriers to Entry

•  ISN™ technology; Patents; Suite of proprietary software design tools; Highly experienced design team; Multi-year technology lead

Ø  Late Stage Development Company on the Cusp of Commercialization •  Developing commercial designs in collaboration with two Filter Manufacturers (Fabricators or

Fabs) of RF front-end devices

5 NASDAQ: RESN |

Market Challenges and Resonant’s Solution

Ø  The RF front-end industry is undergoing dramatic increases in growth and complexity due to: •  Band proliferation •  Carrier Aggregation (CA) •  Multiple-Input, Multiple-Output (MIMO)

Ø  This significant increase in complexity is resulting in a rise in the number of SKUs, higher costs, and longer time to market

Ø  These trends play to Resonant’s strength in design, modeling and novel approaches to dramatically reduce the size and cost of the RF front-end

Ø  Resonant has created a disruptive circuit design platform that can help alleviate this problem by improving single-band filters, and most importantly, creating highly novel and efficient solutions to more complex filter challenges

Band Proliferation Is Driving the Need for More Filters

One model with eight filters

Three models with 31-35 filters each

RF content increased 35% to $15.50 for “SKU Consolidation”*

As carriers use more data bands, mobile devices need more filters creating a significant market opportunity

9 NASDAQ: RESN |

Two-Pronged Commercialization Strategy

Traditional surface acoustic wave (SAW) filters struggle in “hard bands”

Therefore, manufacturers use more expensive bulk acoustic wave (BAW) filters

ISN™ can improve SAW filters to work in difficult bands and reduce manufacturing cost

A filter that can “tune” to multiple bands could replace several existing filters resulting in significant size and cost savings

Resonant is developing such a tunable filter

ISN technology can also deliver cost-effective designs for complex filter multiplexing

Single Band Designs: Improve Existing Filters

Tunable Designs: From Many Filters to One

10 NASDAQ: RESN |

ISN™ Enables a New Class of Single Band SAW Filters Targeting extremely high volume filter opportunities

Product 1 – Band 3 TC-SAW Duplexer Ø  Completed 1st generation (1.8x1.4mm) and 2nd generation (1.7x1.3mm) designs

for this high-volume, traditionally BAW band with competitive performance to existing products

Ø  Commenced work on 3rd generation product (1.6x1.2mm), which will provide a further cost reduction

Ø  Currently formalizing a business relationship with the Filter Manufacturer (Fab) in order to commence licensing to the Fab for sale to the module market

Product 2 – Also a Major Worldwide Band Ø  Engaged a second filter manufacturer (Fab) in March 2015 Ø  This design is a SAW duplexer for another high-volume, BAW/TC-SAW band Ø  First parts have been received; next steps include a revised design turn

Ø  On track to complete no later than Q1 2016

RF Filter Opportunities continue to grow because of industry

constraints on both supply and design

Resonant’s Tunable Filters Will Reduce the Number Front-end Filters Needed

WW Average Cost Filter Set (2017) $1.85

Cost of Tunable Filter (Projected) < $1.00

Difference (Enabled Margin) > $0.85

Enabled margin could increase even further by reducing the number of power

amplifiers and switches as a result of Resonant technology
