American Power Group Corporation Reports First Quarter Results
Quarterly Revenue Increases 111 Percent; Gross Profit Triples; Positive EBITDA Quarter

Lynnfield, MA - February 13, 2014 - American Power Group Corporation (OTCQB: APGI)today announced results for the three months ending December 31, 2013. Several areas of notable progress are as follows:

Financial Highlights:

• Q1 quarterly revenue of $1.84 million which increased 111 percent over the prior year quarter.

• Q1 oil and gas conversion revenue was almost 4 times the same quarter last year with strong Canadian demand accounting for a majority of the increase. Over 280 units in the field as of December 31^st with several customers running over 50 dual fuel engines each.

• Q1 North American vehicular shipments of 51 units was over half of all North American shipments during fiscal 2013. Over 350 vehicular conversion kits sold since 2011 with a majority sold in North America.

• Q1 gross profit margin was 49 percent or $902,000 as compared to 34 percent or $301,000 last year.

• Q1 net loss decreased 74 percent to $164,000 as compared to $639,000 last year. We were EBITDA (Earnings before Interest, Taxes, Depreciation and Amortization) positive for Q1 2014.

Lyle Jensen, American Power Group Corporation’s Chief Executive Officer, stated “Q1 stationary oil and gas conversion revenue of $1.3 million was almost 4 times higher than the same period a year ago, and approximately half of the stationary revenue growth during the quarter was generated from our new Canadian market. At the recent World LNG Fuels 2014 Conference in Houston, several leaders in the oil and gas exploration area were projecting a steady growth in the use of dual fuel natural gas systems in North America - potentially reaching 50% penetration by 2020 which would equate to 3,000 to 4,000 engines. This industry projection would create an APG addressable market just for drilling and fracturing of $100 million to $150 million so our best days are clearly ahead of us.”

Mr. Jensen added, “The North American Class 8 heavy-duty vehicular market is our largest addressed market for natural gas conversions with over 3.5 million vehicles on the road today. North American vehicular conversion revenue for Q1 was a record quarter at $520,000. Early-adopter vehicular evaluations from fiscal 2013 are beginning to generate follow-on production orders. We have approximately 10 customers who have ordered an additional 5 to 14 systems during the past several months.”

“In addition to APG’s conversion of existing fleets, our glider product provides us with a clear path to put APG’s dual fuel system on new 2014 Freightliner Columbia or Coronado cabs and a rebuilt engine. The current glider industry produces approximately 3,000+ diesel gliders per year. With the benefits of adding APG’s dual fuel solution to a glider, several of the larger glider players believe they can double their glider volumes over the next several years. During fiscal 2014, we expect to sell several hundred glider conversions with the potential for that number to grow very quickly as customers continue to validate the significant cost savings associated with APG’s dual fuel glider conversion.”

Mr. Jensen concluded, “Our WheelTime Dealer Network relationship continues to develop with strong early adopter representation in over 30 states. In the last 90 days, WheelTime has presented APG’s technology to 106 new prospective customers. Seventy-

five percent of those visits created early-adopter quotations for one or two evaluation vehicles. WheelTime is now working to turn those quotes into orders which should eventually lead into follow-on conversions.”
