Financial Report

The majority of revenue for 2012 is comprised of sales from To Go Brands, which Cardium acquired on September 28, 2012. Pro forma revenues for the full year ended December 31, 2012, which includes the nine-month period prior to Cardium’s acquisition of To Go Brands, totaled $2.9 million, compared to revenues of $4.5 million for the year ended December 31, 2011. The decrease in revenue during this period reflects consolidation activities by To Go Brands prior to Cardium’s acquisition of the company in September 2012. This unaudited, pro forma consolidated financial information will be outlined in footnote 3 of Cardium’s annual report on Form 10-K to be filed with the SEC.

For the year ended December 31, 2012, Cardium reported revenue of $0.8 million compared to no revenue reported for the year ended December 31, 2011. Total revenue for the fourth quarter ended December 2012 was $0.7 million, primarily comprised of sales from To Go Brands, compared to no reported revenue for the same period in 2011.

Cardium reported a net loss of $8.3 million, or $(0.07) per share, for the year ended December 31, 2012, compared to a net loss of $7.1 million, or $(0.08) per share for the year ended December 31, 2011. For fourth quarter ended December 31, 2012, the Company reported a net loss of $2.0 million, or $(0.02) per share, compared to a net loss of $2.1 million net loss, or $(0.02 per share), in the fourth quarter in 2011.

For the year ended December 31, 2012, research and development expenses totaled $2.6 million and selling, general and administrative expenses were $6.1 million, compared to $2.6 million and $4.8 million, respectively, for 2011. The increase in expenses was primarily due to expenses associated with the market introduction of Excellagen, initiation of the Company’s Generx ASPIRE clinical study, and for Cardium’s nutraceutical initiative, which served as the catalyst for the acquisition of To Go Brands, Inc. Research and development costs for the three months ended December 31, 2012 totaled $0.5 million and selling, general and administrative expenses were $1.8 million, compared to $0.7 million and $1.2 million, respectively, for the same period last year.

Cardium ended the 2012 year with a total of $2.3 million in cash compared to $4.7 million in the previous year. During the year ended December 31, 2012, the Company raised $4.6 million in net proceeds through the completion of a registered direct equity financing with three institutional and accredited investors with the issuance of 17.9 million shares of Cardium common stock priced at $0.28 per share with no warrant coverage and through the sale of 5.2 million shares of common stock under at-the-market transactions for net proceeds of $1.9 million. In connection with the acquisition of the To Go Brands, Inc., the Company issued 9.6 million unregistered shares of common stock. The total shares of common stock outstanding at December 31, 2012 were 129.2 million compared to 96.6 million shares of common stock outstanding at December 31, 2011.

During the period since December 31, 2012, cash flows from financing activities include the sale of 343,749 shares of common stock in at-the-market transactions for net proceeds of $65,743, and as reported today, Cardium has entered into a definitive agreement with Sabby Management LLC (“Sabby”), the Company’s largest shareholder, for a preferred stock financing of up to $4.0 million in gross proceeds. A more complete description of the terms and conditions of the financing is provided in a press release dated today and will be available in the Form 8-K to be filed by the Company with the Securities and Exchange Commission.

In first quarter 2013, the Company reported that its exchange listing compliance plan submitted on December 6, 2012 had been accepted by the NYSE MKT. As previously reported, a communication from the staff of the Company’s current listing exchange indicated that the Company was considered to be noncompliant with certain listing requirements based on its quarterly report for the period ended September 30, 2012, and provided that the Company should submit a plan to staff of the exchange that would re-establish compliance with the NYSE MKT listing requirement by March 31, 2013. On December 6, 2012, the Company reported that it had submitted a plan designed to reestablish compliance with the exchange’s requirement, and reported on January 16, 2013 that the plan had been accepted by the listing exchange. The Company reports that in view of the proposed preferred stock financing, the NYSE MKT has granted an additional quarterly extension of the listing exchange compliance plan from March 31 to June 30, 2013, although as is normal course, the Company’s exchange compliance would continue to be evaluated on an ongoing basis.

The Company also indicated that similar to 2011, the audit opinion accompanying its consolidated financial statements for the year ended December 31, 2012, will contain a going concern qualification from its independent registered public accounting firm, Marcum LLP. Consistent with its business strategy and as outlined in this press release, Cardium plans to raise additional funds through the strategic sale or monetization of its operating units, entering into strategic licensing agreements, through the future sales of Excellagen and To Go Brand’s products, and/or other financing transactions.

Excellagen Commercialization Plans

Since the introduction of Excellagen, the Company has entered into agreements with selected regional sales distributors and independent sales representatives to market Excellagen into their specific geographic and special markets. These agreements allow for flexible transitions as strategic partnerships are achieved. In January 2013, Cardium announced the distribution agreement with Academy Medical, LLC to market, sell and distribute Excellagen to U.S. government medical providers. Academy Medical has a growing customer base of over 35 Veterans Administration (VA) and military hospitals within the U.S. Cardium also recently announced an agreement with an independent regional distributor group consisting of ten sales

representatives to market, sell and distribute Excellagen to podiatric and orthopedic physicians, plastic surgeons, hospitals and surgical centers. The Company plans to enter into additional agreements designed to support the market introduction of Excellagen into a variety of regional markets and to broaden its potential applications in wound care.

Consistent with the Company’s long-term business strategy, Cardium is also focused on establishing strategic partnerships that would cover the marketing and sale of Excellagen into U.S. vertical wound healing market channels, including: (1) podiatry, (2) wound care centers, hospitals, and long-term care facilities, (3) government agency providers (such as the U.S. Department of Veterans Affairs, Bureau of Indian Affairs and military hospitals), (4) dermatology and plastic surgery, and (5) orthopedic surgery. The Company’s commercialization strategy is similar to other companies in the advanced wound care space. For example, GraftJacket^® products developed by Wright Medical are now being marketed and sold by Kinetic Concepts Inc.; TEI Biosciences’ products are being sold by Boston Scientific, Medtronic and Stryker; and Cook Medical’s Oasis^® products are currently being marketed and sold by Healthpoint Biotherapeutics.

Cardium is advancing forward with the reimbursement process for Excellagen with Centers for Medicare & Medicaid Services (CMS) and private insurance providers. Already-established standard CPT^® procedure reimbursement codes may apply when Excellagen is used with surgical debridement procedures and through the DRG reimbursement system for in-hospital surgical procedures, as well as in long-term care facilities and through their service providers.

Internationally, Cardium plans to obtain a CE Mark for the potential marketing and sale of Excellagen in the European Union, which consists of 27 member countries. The Company expects to be in a position to obtain a CE Mark for Excellagen in second quarter 2013. Cardium also has a marketing and distribution agreement with BL&H Co. for the marketing and sale of Excellagen in South Korea, which is currently advancing through the regulatory and reimbursement pricing process. In addition, Advanced Biosciences Research, an affiliate of bioRASI, is assisting Cardium for the planned commercialization of Excellagen in Russia and the eight additional member countries comprising the Commonwealth of Independent States (CIS).

Excellagen is a novel syringe-based, professional-use, pharmaceutically-formulated 2.6% fibrillar Type I bovine collagen gel that functions as an acellular biological modulator to activate the wound healing process and significantly accelerate the growth of granulation tissue. Excellagen’s FDA-clearance provides for very broad labeling including partial and full-thickness wounds, pressure ulcers, venous ulcers, diabetic ulcers, chronic vascular ulcers, tunneled/undermined wounds, surgical wounds (donor sites/graft, post-Mohs surgery, post-laser surgery, podiatric, wound dehiscence), trauma wounds (abrasions, lacerations, second-degree burns and skin tears) and draining wounds. Excellagen is intended for professional use following standard debridement procedures in the presence of blood cells and platelets, which are involved with the release of endogenous growth factors. Excellagen’s unique fibrillar Type I bovine collagen gel formulation is topically applied through easy-to-control, pre-filled, sterile, single-use syringes and is designed for application at only one-week intervals. In addition, Excellagen has been engineered to serve as a delivery platform enabling multiple device and therapeutic product extensions to include antimicrobials, small molecule drugs, peptides, conditioned cell media, stem cells and DNA-based biologic products. Additional information about Excellagen can be viewed at www.excellagen.com.

Generx Commercialization Plans

Generx (Ad5FGF-4) is a disease-modifying regenerative medicine biologic that is being developed to offer a one-time, non-surgical option for the treatment of myocardial ischemia in patients with stable angina due to coronary artery disease, who might otherwise require surgical and mechanical interventions, such as coronary artery by-pass surgery or balloon angioplasty and stents. Similar to surgical/mechanical revascularization approaches, the goal of Cardium’s Generx product candidate is to improve blood flow to the heart muscle – but to do so non-surgically, following a single administration from a standard balloon angioplasty catheter.

In March 2012, Cardium announced the initiation of the Generx ASPIRE Phase 3 registration study to evaluate the therapeutic effects of its lead product candidate Generx in patients with myocardial ischemia due to coronary artery disease. The ASPIRE study, a 100-patient, randomized and controlled multi-center study to be conducted at up to nine leading cardiology centers in the Russian Federation, is designed to further evaluate the safety and effectiveness of Cardium’s Generx DNA-based angiogenic product candidate, which has already been tested in clinical studies involving 650 patients at more than one hundred medical centers in the U.S., Europe and elsewhere. The efficacy of Generx will be quantitatively assessed using rest and stress SPECT (Single-Photon Emission Computed Tomography) myocardial imaging to sensitively measure improvements in microvascular cardiac perfusion following a one-time, non-surgical, catheter-based administration of Generx. The Cedars-Sinai Medical Center Nuclear Cardiology Core Laboratory in Los Angeles, California, is the central core lab for the study and is responsible for the analysis of SPECT myocardial imaging data electronically transmitted from the Russian medical centers participating in the ASPIRE study. The Russian Health Authority has assigned Generx the therapeutic drug trade name of Cardionovo^® for marketing and sales in Russia.

To Go Brands^® Nutraceutical Brand Platform

On September 28, 2012, Cardium acquired the business assets and product portfolio of To Go Brands^® to support the expansion of Cardium’s health sciences nutraceutical platform and to provide a revenue platform for the potential growth of the business. With a portfolio of over 25 products, To Go Brands’ nutraceutical powder mixes, supplements and chews are being sold through mass, food and drug channel retailers and To Go Brands’ web-based store. To Go Brands’ experienced management team has key contacts and a track record of developing and placing new and innovative health and nutraceutical products into retail channels. To Go Brands has now assumed operational responsibility for Cardium’s nutraceutical initiative, which includes the Company’s strategic investment in SourceOne Global Partners, a leading supplier of science-based ingredients and proprietary formulas, and the MedPodium Nutra-Apps^® product line.

The Company recently announced the expansion of its To Go Brands VitaRocks^® Kids vitamin product line and the broadened retail distribution of the newly-designed products into select Target stores nationwide. VitaRocks are inspired by a popping pellet candy that is popular with kids and represents a next-generation, easy-use delivery platform for multivitamins and nutrients, dietary supplements, and potentially over-the-counter (OTC) medicines for children, as well as adults.

The Company’s 2013 plans for To Go Brands include (1) completing new packaging and message re-design to update the look of current products; (2) increasing online customer acquisition and retention by introducing super affiliate programs and social media-based coupon offerings (e.g. LivingSocial); (3) expanding and leveraging the VitaRocks children’s vitamin product line; and (4) expanding U.S. retail distribution and establishing international distributors to leverage on the success of To Go Brands’ lead product, Trim Green Coffee Bean™ dietary supplement.

Since 2007, To Go Brands has been making healthy, great tasting and anti-oxidant-rich phytonutrients and nutraceutical supplements in an array of easy use formats, including drink mixes, chews, powders and capsules, to empower busy lifestyles in today’s fast-paced, tech-driven world. The Go Active! product line includes High Octane^®, Green Tea Energy Fusion™, Acai Natural Energy Boost™, and Neo-Energy^®. The Go Healthy! product line includes Greens to Go^®, Extreme Berries to Go^®, Healthy Belly^®, VitaRocks^®, and Neo-Chill™. Go Trim! products include Smoothie Complete^®, Trim Energy Green Coffee Bean™, Trim Energy^®, and Neo-Carb Bloc^®. To Go Brands products are sold through mass, food and drug channels at retailers including Whole Foods, Sprouts, Kroger, GNC, RiteAid, Jewel-Osco, Ralph’s Supermarkets, Vitamin World, Meijer, Fred Meyer, King Soopers, and the Vitamin Shoppe as well as directly from the company’s web-based store.

Cardium’s In-House Initiatives

The Company recently announced its partner-enabled internal product development, LifeAgain™, a medical analytics and e-commerce platform that is focused on the development, marketing and direct sales of new and innovative survivable risk, multi-year, non-convertible level term life insurance programs and other insurance products, that are currently non-accessible and unaffordable for certain sub-groups of highly motivated buyers considered “uninsurable” based on traditional underwriting standards by U.S. life insurance companies. Traditional life insurance has become an over-optimized web-marketed, undifferentiated, low priced commodity largely marketed to healthy people. LifeAgain is being developed based on improvements in relative mortality in certain sub-group populations, including cancer patients and patients with chronic medical diseases, as a result of the success of early diagnostic screening, public education, the introduction of advanced drugs and biologics, improved and optimized therapies, and expanded access to healthcare.

In addition, the Company will seek to initiate a partner-enabled pilot Phase 2b/3 clinical study for Genedexa™ (Ad5PDGF-B), formerly referred to as the Company’s Excellarate product candidate. Genedexa’s initial clinical development focus will be for the treatment of chronic, non-healing diabetic foot ulcers. The Company has completed the MATRIX-1 (Phase 1/2) and MATRIX-2 (Phase 2b) clinical studies and the planned Genedexa pilot study represents an important next step forward towards FDA registration of Cardium’s advanced DNA biologic wound care product. Genedexa represents the first product candidate based on the Company’s Excellagen product platform and is comprised of the FDA-cleared Excellagen collagen topical gel and an adenovector gene therapy with DNA encoding for PDGF-B protein. PDGF-B is believed to promote wound healing by directly stimulating cells involved in wound repair and also by eliciting the production of other growth factors. The Genedexa product candidate, a DNA-based biologic, requires data from clinical studies demonstrating patient safety and efficacy prior to filing for a Biologic License Application (BLA). The Company may use alternative independent private financings and strategic partners to finance the clinical development of Genedexa and commercialize its LifeAgain platform.
