The following provides an update on the litigation commenced in Federal district court against Michael Davis and the Rudolph Steiner Foundation and supplements the information provided in the Prior Filings.

Background

In May 2016, Meridian changed its filing status with respect to its investment in Cyanotech from passive to active after becoming aware of highly unusual governance and management practices at the company, practices which it believed to be both in conflict with well-established public company governance norms and contrary to the interests of the company's outside shareholders.

On May 6, 2016, Meridian delivered a letter to Cyanotech's board of directors which detailed specific concerns relating to the unusual activities of Michael Davis as a board member and a shareholder of the company.  When Cyanotech's board refused to discuss these issues with Meridian, Meridian filed suit in Federal court in order to address the necessary governance reforms.  Around the same time, Meridian began making filings on Schedule 13D to alert the company and its fellow shareholders to the findings of Meridian's continuing research.

A central item discovered in Meridian's research is the close long-term relationship between Michael Davis and the Rudolph Steiner Foundation ("RSF").  As discussed in Amendment No. 8, Meridian believes the Davis/RSF partnership is based upon their shared appreciation of the "spiritual" teachings of Rudolph Steiner, a German philosopher who died in 1925.  As communicated by RSF on its website and in its literature, central to the teaching of Rudolph Steiner is the belief that mankind threatens to outstrip the resources of our planet and that proper ecological stewardship requires an investment strategy that deemphasizes growth and economic profit.  For nearly a decade prior to their collaboration at Cyanotech, Davis and RSF have been partners in "Filigreen Farm", a property located in Mendocino California.  RSF owns the land, but Davis leases the property and, according to the tax filings of one of the entities he controls, has invested millions of dollars creating a biodynamic demonstration farm that in the future could be used to provide environmental education opportunities.


As discussed in Amendment No. 8, Meridian believes Davis intends Cyanotech to be another Rudolph Steiner-inspired ecology project, and this makes RSF the ideal partner for accumulating and holding a control position in the company.  In RSF, Davis has not only a partner with the highly-unusual characteristic of requiring no economic return, but also someone with whom he can expect loyalty due to Davis' significant ongoing financial support at Filigreen Farm.

In its most recent 13D filing, Amendment No. 11, Meridian reported its identification of the likely reason Davis felt it necessary to find a partner with whom to periodically "park" shares of Cyanotech that he acquired or wished to acquire in excess of a 20% ownership threshold.  Davis conducts much of his business through a network of not-for-profit entities that he controls.  These entities are subject to oversight from the Internal Revenue Service and the restrictions created by Section 4943 of the Internal Revenue Code.  Section 4943 reflects Federal tax policy that not-for-profit entities are not to be used to control business enterprises.  As such, Section 4943 establishes severe financial penalties whenever a not-for profit owns more than 20% of a business enterprise.  By splitting the Cyanotech shares he acquired (or that he caused to be acquired) between entities he controls directly and entities RSF controls, Davis managed to accumulate a combined 33% ownership stake with neither he nor RSF ever directly holding more than 20%.

Davis seems to believe that the penalties created by Section 4943 for one not-for-profit owning more than 20% of a business enterprise can be side-stepped via an ownership structure involving two not-for-profits owning a combined 33% position.  However, Meridian believes that Davis and his counsel may have failed to take into account the "group" ownership rules under the Securities Exchange Act of 1934.  Meridian believes this explains why Davis and RSF have steadfastly refused to acknowledge the existence of a "group", as such acknowledgment might trigger millions of dollars in penalties under Section 4943 of the Internal Revenue Code.

Again, Davis Should Not Be In Control of the Lawyers

One of the issues Meridian raised in its May 6, 2016 letter to Cyanotech's board of directors was the troubling matter of Davis causing the company to change its outside legal counsel from a Hawaii-based corporate law firm to a San Francisco-based law firm (Farella Braun) that describes itself as a litigation specialist, and which also has a large practice representing family foundations and not-for-profits.  When Davis pushed for the change to this new law firm, Cyanotech's management objected noting the conflict-of-interest that would exist because the firm already represented Davis personally.  Meridian understands that promises were made by both Davis and the law firm to end their personal relationship, but in its research, Meridian frequently sees Farella Braun listed as the "contact" on web pages that provide information on Davis' various not-for-profit entities and notes that Farella Braun is still named as agent within the Federal tax returns filed by those entities.

In its May 6, 2016 letter, Meridian challenged the company, asking to whom does external counsel report, is it to the company's CEO and CFO as would normally be the case, or does counsel report to Davis?  Meridian's belief that external counsel works at the behest of Davis increased upon learning that Cyanotech had terminated payments and other benefits promised under the severance agreement with the company's former CEO.  Cyanotech's action appears to have triggered quick legal action by the former CEO and a dispute resolution process that may result in Cyanotech paying not just what was owed under the severance agreement, but the attorneys' fees for both sides in the dispute.  While the risks and costs associated with this dispute might be in the interests of Davis and his litigation-oriented associates at Farella Braun, Meridian is doubtful that either management or the company's outside shareholders see any benefits accruing from a legal battle with the former CEO.

The continuing harm from the apparent delegation of legal decisions to Davis can be seen in the company's most recent 10-Q disclosure that Cyanotech's legal expenses for the first nine months of the fiscal year had increased by more than $1.3 million over the prior year.  This is a huge sum for a small company, and a spectacular amount considering that neither litigation has advanced beyond the initial pleading stage.  Cyanotech appears to have spent more than $1 million filing motions to dismiss Meridian's litigation, a strategy that Meridian believes suggests a very strong desire to avoid commencement of the legal discovery process.


Meridian Removing Cyanotech from Litigation Against Davis and RSF

Since delivery of its May 6 letter, Meridian has repeatedly been surprised by the lack of fiduciary responsibility taken by Davis' colleagues on Cyanotech's board of directors.  Again and again, they seem willing to look the other way with respect to obvious conflicts of interest.  Recognizing now that Davis is incented to spend heavily on litigation rather than admit that he has formed a "group" with RSF, and that Cyanotech's board is willing to permit the company to assume very significant costs resulting from such litigation, Meridian believes the interests of Cyanotech's shareholders are best served by removing the company from the litigation.

Further, Meridian believes much of the benefit shareholders are likely to receive from the company have already been obtained.  To date, the litigation has caused:

·
Cyanotech to conduct an investigation into Davis' activities
·
Cyanotech to deliver a summary report to shareholders on the findings of the investigation
·
Cyanotech to add disclosure to its corporate filings relating to Davis' unusual relationship with RSF
·
Davis to begin making his ownership reports on the correct form, Schedule 13D
·
Davis to be removed as a member of the company's audit committee

Of course, removing the company from the litigation does not mean that Davis will not try to have Cyanotech continue to bear the costs.  Davis may try to have the company indemnify him under the company's corporate indemnification policy.  However, Meridian believes any such indemnification would violate the terms of the company's indemnification policy and Nevada law, and expose the board to substantial liability.  This because the issue in dispute does not relate to Davis' role as a board member, but rather to his continuing failure as a shareholder to make proper ownership filings under the Securities Exchange Act of 1934.

Unfortunately, Cyanotech's board has repeatedly demonstrated its inability to make sound governance decisions.  Meridian believes this stems largely from the board's seeking advice from litigation-oriented legal counsel that was hand-selected by and that appears to remain loyal to Davis.  Examples of recent poor governance practices/decisions include:

·
Electing not to speak to Meridian following receipt of the May 6, 2016 letter
·
Requiring four months and the assistance of special outside counsel to conclude that Davis is ineligible to report his ownership on short-form Schedule 13G
·
Waiting eight months before reorganizing the company's audit committee to remove Davis, whose presence created risks for the company under Nasdaq rules
·
Renominating Davis to serve on the board while Davis was the subject of an ongoing internal investigation
·
Asking shareholders to vote on director nominations in August 2016 before the company disclosed the results of its investigation into Davis' actions
·
Failing to deliver more than a cursory summary of the findings of the investigation to shareholders and then informing Meridian that the investigation report concerning Cyanotech's governance practices is considered "attorney client privileged" and thus immune from discovery in any litigation
·
Allowing excessive litigation costs to be incurred, which the company disclosed in its most recent 10-Q, has reduced available cash and thereby negatively impacted the company's operations

Meridian does not understand why Cyanotech's other directors continue to shield and protect Davis at the expense of the company's other shareholders.  Hopefully an end to the company's involvement in the litigation will provide Cyanotech's board the opportunity to reconsider where their proper fiduciary duties lie.
