NOTE

ORGANIZATION

NovaBay Pharmaceuticals, Inc. is a biopharmaceutical company focusing on commercializing and developing its non-antibiotic anti-infective products to address the unmet therapeutic needs of the global, topical anti-infective market with its

two

distinct product categories: the NEUTROX

family of products and the AGANOCIDE

compounds. The Neutrox family of products includes AVENOVA

for the eye care market, NEUTROPHASE

for the wound care market, and CELLERX

for the aesthetic dermatology market. The Aganocide compounds, still under development, have target applications in the dermatology and urology markets.

The Company was incorporated under the laws of the State of California on

January

19,

2000,

as NovaCal Pharmaceuticals, Inc. It had

operations until

July

2002,

on which date it acquired all of the operating assets of NovaCal Pharmaceuticals, LLC, a California limited liability company. In

February 2007,

it changed its name from NovaCal Pharmaceuticals, Inc. to NovaBay Pharmaceuticals, Inc. In

June 2010,

the Company changed the state in which it was incorporated (the “Reincorporation”) and is now incorporated under the laws of the State of Delaware. All references to “the Company” herein refer to the California corporation prior to the date of the Reincorporation and to the Delaware corporation on and after the date of the Reincorporation. Historically, the Company operated as

four

business segments. In

April 2016,

the Company dissolved DermaBay, a wholly-owned U.S. subsidiary that was formed to explore dermatological opportunities. At the direction of its Board of Directors, the Company is now focused primarily on commercializing Avenova for managing hygiene of the eyelids and lashes in the United States and is managed as a single segment.

Effective

December 18, 2015,

the Company effected a

-for-

reverse split of its outstanding common stock (the “Reverse Stock Split”). The accompanying financial statements and related notes give retroactive effect to the Reverse Stock Split.

Liquidity

Based primarily on the funds available at

June 30, 2019,

the Company believes these resources will be sufficient to fund its operations through the

third

quarter of

2019.

The Company has sustained operating losses for the majority of its corporate history and expects that its

2019

expenses will exceed its

2019

revenues, as the Company continues to re-invest in its Avenova commercialization efforts. The Company expects to continue incurring operating losses and negative cash flows until revenues reach a level sufficient to support ongoing growth and operations. Accordingly, the Company's planned operations raise substantial doubt about its ability to continue as a going concern. The Company's liquidity needs will be largely determined by the success of operations in regard to the commercialization of Avenova. The Company also

may

consider other plans to fund operations including: (

) out-licensing rights to certain of its products or product candidates, pursuant to which the Company would receive cash milestones or an upfront fee; and (

) raising additional capital through debt and equity financings or from other sources. The Company

may

issue securities, including common stock and warrants, through private placement transactions or registered public offerings, which would require the filing of a Form S-

or Form S-

registration statement with the Securities and Exchange Commission (the “SEC”). In the absence of the Company's completion of

one

or more of such transactions, there will be substantial doubt about the Company's ability to continue as a going concern within

one

year after the date these financial statements are issued, and the Company will be required to scale back or terminate operations and/or seek protection under applicable bankruptcy laws. The accompanying financial statements have been prepared assuming the Company will continue to operate as a going concern, which contemplates the realization of assets and the settlement of liabilities in the normal course of business. The consolidated financial statements do

not

include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts of liabilities that

may

result from uncertainty related to its ability to continue as a going concern.
