We urge you to review those filings, together with our current SEC filings, because they contain important information.

Now, I will turn the call over to David Demers.

David Demers

Good morning everyone and thank you for joining representatives from Westport and Fuel Systems Solutions on today’s call. I believe this is a watershed event in the industry as we jointly announce that our respective companies have entered into a merger agreement to create a single company.

I will take you through some of the highlights in the context of Westport’s strategic plans and will then pass the call over to Mariano to take you through the strategic rationale of the merger from the perspective of Fuel Systems, followed by Nancy and Andrea to discuss the operational highlights, and then by Pietro and Ashoka to discuss the transaction process and financial details.

Slide 5

Let’s begin on slide 5 where I’ll cover the particulars of the transaction for you:

Slide 6

The press release and other speakers today may provide additional color about the benefits of the merger but I want to spend a moment talking about Westport’s view of this exceptional combination. Moving on to slide 6, the new company is expected to benefit from complementary product solutions and a global footprint, with efficient operations and a core focus in developing next generation technology.

We believe there are several significant benefits of this proposed merger for Westport shareholders including but not limited to:

Now, I’ll turn the call over to Mariano Costamagna to take you through the strategic rationale of the merger from the perspective of Fuel Systems.

Mariano Costamagna

Slide 7

Thank you David. Let’s move to slide 7.

Ten months ago, Fuel Systems Solutions’ board of directors formed a Strategic Oversight Committee whose purpose was to advance the company’s strategic priorities and drive value for all shareholders. This Committee conducted a lengthy strategic evaluation process, and determined that this opportunity creates significant returns for our shareholders. Merging with Westport Innovations accomplishes several objectives:

The exchange ratio of this merger represents a 10.0% percent premium to Fuel Systems shareholders based on the closing trading prices of Westport’s and Fuel Systems’ shares on August 31, 2015.

Let’s move to the next slide.

Slide 8

As you can see on slide 8, Fuel Systems is the 3^rd, and Westport the 7^th, largest alternative fuel systems solutions player based on 2014 revenues. Together, we represent the 2^nd largest. Not only will this merger create scale, it creates a strong platform for growth in all of our addressable markets from which to best serve our customers.

3

Combining our businesses and our brands increases our scale and our relevance around the world in all of our end markets, and positions the resulting company to compete more efficiently and effectively once markets turn healthier.

Westport’s traditional focus on the medium- and heavy-duty, as well as high horsepower arenas, and Fuel Systems’ significant experience in light- and medium-duty products for automotive and industrial applications are highly complementary. Combining them results in a powerful, comprehensive offering across multiple applications, end markets, and geographies.

Fuel Systems is confident that we have found the right partner for our customers, suppliers, employees, and shareholders, and we look forward to working together as we integrate the two companies.

I’ll now turn the call over to Nancy Gougarty and Andrea Alghisi to discuss the operational highlights of the transaction.

Nancy Gougarty

Slide 10

Thank you Mariano. I will focus on providing operational highlights and priorities for the combined Company on slide 10.

As David and Mariano discussed earlier, this complementary industry expertise of Westport and Fuel Systems provides a compelling rationale for the merger, as the combined company’s product development efforts will span passenger car to heavy-duty trucks to locomotive and marine applications to stationary power. The combined company will have a broad global reach, and will be able to serve some of the world’s largest and fastest growing markets through a fortified geographic footprint, greater product diversity, and a leading distribution network spanning 70 countries.

Moving to slide 11…

Slide 11

The merger combines 17 brands in the automotive and industrial space and will allow customers and stakeholders to benefit from the consolidation of technologies, and the expansion of product portfolios, OEM relationships, and global distribution networks.

Fuel Systems brings brands such as BRC Gas Equipment, which designs and manufactures CNG and LPG automative components and systems, as well as reputable IMPCO Automotive, which is dedicated to bi-fuel and mono-fuel systems in the North American market. Other brands in Fuel Systems’ portfolio include Zavoli, GFI Control Systems, TA Gas Technology, amongst others. On the Industrial side, Fuel Systems’ IMPCO brand is recognized around the world.

Westport brings the cutting edge leader in bi-fuel and dedicated CNG and LPG for Ford Trucks, through Westport WiNG, in addition to strength in fuel system components from EMER and OMVL, and Valtek, as well as Westport Parts and Service and Westport iCEPACK. Additionally, Westport’s proprietary HPDI technology will continue to be a strategic focus of the combined company.

I’ll now turn the call over to Andrea Alghisi to further discuss our operational highlights of the merger.

Andrea Alghisi

Slide 12

Thank you, Nancy.

On slide 12:

Both companies bring long standing, vital relationships with several key global OEMs. Fuel Systems brings relationships with automotive companies such as General Motors Company, Ford Motor Company, Nissan Motor Company, Kia Motors Company, Subaru of Fuji Heavy Industries, and Mitsubishi Group, amongst others, as well as relationships with industrial companies such as Caterpillar, Linde, CombiLift, and Clarke, among others.

Wesport has key relationships with complementary global OEMs, including but not limited to Volvo Car Group, Volkswagen, Fiat, Tata Motors, GAZ Group, Chrysler, PACCAR, Daimler AG, Weichai, Cummins, Ford, Volvo AB, amongst others.

The combined customer base and communities will be served with an outstanding asset base and state-of-the-art facilities strategically located across 5 continents.

Moving to slide 13.

Slide 13

We expect each company’s proven track record of product development will strengthen as a result of the combination, and benefit from capital-efficient and optimized research and development programs. The combined companies will create a stronger innovation platform to invest in developing new products and new technologies, and will be positioned to fuel future growth better than either company on a standalone basis.

The combined company will have filed over 500 patents in CNG/LNG/LPG parts and systems worldwide. This combination of a strong intellectual property position, prolific development and commercialization efforts will help expand the product pipeline for the industry.

Let’s move to slide 14.

Slide 14

From a management standpoint, the company will operate under the name Westport Fuel Systems and will be headquartered in Vancouver, Canada with a new business unit called Fuel Systems Automotive and Industrial Group. This new unit will represent the combination of Fuel Systems with Westport Operations, with its automotive division headquartered in Cherasco, Italy, and its industrial division headquartered in Santa Ana, CA.

Mr. David Demers and the rest of the Westport executive team will lead the combined company.

Mr. Mariano Costamagna, who is retiring as CEO of Fuel Systems, will serve in a senior advisory position of the company’s new business unit with additional titles in the organization to be determined at a later date

Top talent across the combined organization will be evaluated and retained based on the organization’s new structure.

Three individuals selected by Fuel Systems, including Mariano Costamagna, and two directors to be confirmed, will be nominated for addition to the combined company’s Board of Directors. As Westport’s Board of Directors will remain the same size, three current directors of Westport are expected to be replaced by the new Fuel Systems directors.

I’ll now turn the call over to Pietro Bersani and Ashoka Achuthan to dicuss our financial highlights of the merger.

Pietro Bersani

Slide 16

Thank you, Andrea. I’ll be providing you with transaction details and Ashoka will discuss the financial highlights of the merger agreement for the proposed merger of Westport with Fuel Systems. Moving to slide 16.

As David mentioned, under the terms of the merger, Westport and Fuel Systems will merge with Westport acquiring all of the outstanding shares of Fuel Systems common stock in a stock-for-stock transaction. Westport will create a merger subsidiary into which Fuel Systems will be merged. Fuel Systems shareholders will receive 2.129 Westport shares for each share of Fuel Systems common stock they own at closing. Based on closing stock prices on August 31, 2015, the merger will create a combined company with an equity value of $351 million. The transaction has been unanimously approved by the boards of directors of both companies. Following the closing, existing Westport shareholders will hold approximately 64% of the combined company and Fuel Systems shareholders 36% of the combined company.

Moving to slide 17…

Slide 17

The transaction is subject to regulatory approvals, including expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act and other customary closing conditions noted on the slide.

In addition, the transaction will be subject to the required approval of both Fuel Systems and Westport’s shareholders, which each company will seek. The transaction must be approved by simple majority (50% plus one) of votes cast present in person or by proxy by the Westport shareholders and by Fuel Systems stockholders holding a majority of the outstanding shares of fuel systems common stock. Subject to the satisfaction of closing conditions and receipt of required approvals, the companies anticipate closing the transaction in the 4th quarter of 2015. Westport and Fuel Systems will operate as separate companies until that time.

In terms of the timing of next steps, Westport and Fuel Systems will each provide their respective proxies as they relate to the transaction in advance of their respective special Shareholders Meetings. The Westport Shareholder Meeting is being held in order to approve the issuance of Westport Shares in connection with the transaction and to approve the name change of Westport; the Fuel Systems Shareholder Meeting is being held in order to approve the merger. Upon receipt of all approvals, we expect to close the merger in Q4 2015.

Shareholders can vote in person at their respective meeting or by signing and returning their form of proxy by mail in the self-addressed envelope provided or by fax to the number indicated on the form or online at the website indicated on the form.

Now, I’ll turn the call over to Ashoka Achuthan.

Ashoka Achuthan

Slide 19

Thanks Pietro. Good afternoon everyone. On slide 19…

I will walk you through the transaction’s significant financial positive impacts.

We expect the merger to be accretive to Westport’s earnings per share in 2016, excluding one-time costs, and to ramp to a total of approximately $30 million of annual pre-tax savings and merger synergies fully realized by calendar year 2018. The components of these benefits are:

These benefits solidify Westport’s continuing initiatives to reach adjusted EBITDA positive by mid 2016.

For the year ended December 31, 2015, both Westport and Fuel Systems are reiterating their respective revenue outlooks. Westport expects consolidated revenue to be between $110 million and $125 million for the year, while Fuel Systems expects consolidated revenue to be in the range of $270 to $280 million for the year, resulting in a combined revenue outlook for both companies of $380 to $405 for the year ended December 31, 2015.

On a pro forma basis, the combined company had approximately $117 million in cash and short term investments as of June 30, 2015.

Let’s move to slide 20 -

Slide 20

In closing, both Executive Management teams and boards of directors of Fuel Systems and Westport believe the merger we announced today is compelling.

With a strong revenue base to build on, significant synergy opportunities, a strengthened balance sheet and enhanced liquity, and positive effects on adjusted EBITDA, we believe the combined entity will be a premier alternative fuel engine company and as such will be well positioned for continued investment and long-term financial stability.

We have created web pages for the merger on both Westport’s and Fuel Systems’ web sites.
