Market Conditions and Investment Strategies

For first quarter 2023 transactions, we trimmed Enphase Energy early in the quarter due to a stretched valuation, and deployed
the assets into SolarEdge Technologies, increasing the portfolio weight to 3.5%. Enphase and SolarEdge are in the same markets,
and we believe SolarEdge to be more attractively valued currently with greater exposure to faster growing markets like Europe and
commercial solar. We purchased Zurn Elkay Water Solutions, and trimmed Watts Water Technologies on January stock strength to
fund the new holding in the GEOS water theme. Zurn Elkay is the result of two significant corporate transactions in the past three
years. First, Zurn was spun out from Rexnord Corporation to separate Rexnord’s industrial assets from its water related assets.
And second, Zurn merged with Elkay Water Solutions in July 2022, expanding the geographical footprint and product offerings.
The combined company produces gears, seals and other components that are critical to water and wastewater infrastructure. We
believe the company can grow revenues while expanding company margins with merger efficiencies. In March, we increased our
position in Wolfspeed, the leader in silicon carbide production, utilized in power semiconductors for use in electric vehicles and
renewable energy inverters. Wolfspeed is expanding its manufacturing presence, and announced its second fabrication plant in
Saarland, Germany in February. Plant construction will begin in the second half of this year. We increased Strategy weights in
SunOpta, the alternative milk manufacturer, and Kornit Digital, the garment digital screen printing leader. SunOpta was trimmed
last October, and we added back to the position given strong guidance on fundamentals from management. Kornit stock has been
under pressure for a year, given growth concerns. We believe all the bad news and then some is reflected in the stock share price,
as the $940 million market cap company has a sound balance sheet with over $600 million in cash. The source of funds for the
adds were the sales of solar companies SMA Solar Technology and Sunrun. SMA was sold on valuation, and Sunrun due to our
concerns about the future path for business financing amidst the tighter credit market. Stationary energy storage firm Stem was
sold late in the quarter given financing pressures and a lack of execution, to make room for new renewable energy holding Cadeler.
Cadeler transports and installs offshore wind foundations and turbines using their fleet of jack-up installation vessels. Cadeler will
have the largest fleet of next generation wind turbine installation vessels, amidst a global fleet that is insufficient to meet offshore
wind growth and incapable of installing larger 15+ MW offshore turbines. We believe the high barriers to entry will enable Cadeler
to generate EBITDA margins greater than 60%.

Social Impact Management Update

The Intergovernmental Panel on Climate Change (IPCC) released the AR6 Synthesis Report in March, summarizing the main
findings of the previous six reports in this IPCC cycle. The IPCC reiterated that society needs to rapidly reduce global emissions
to avoid breaching 1.5- or 2-degrees Celsius warming. Immediate action on climate mitigation also has important implications
for the effectiveness of adaptation. Adaptation is critical to help society manage the impacts of climate change, but it is more
effective at lower levels of temperature warming. Finally, the IPCC explained that even if society were to overshoot 1.5 degrees or 2
degrees Celsius of warming, sustaining net negative global emissions for an extended period could return warming to below 1.5- or
2-degrees C. This would require a rapid scale up of carbon dioxide removal technology in addition to the deployment of existing low
carbon technologies.

While the final IPCC report from the Sixth Assessment cycle is a sobering portrayal of the reality of climate change, we believe
it showcases the benefits of near-term action using the commercial low carbon technologies available today. The time value of
carbon states that emissions abated now are more valuable than emissions abated in the future since temperature warming and
other negative climate impacts will continue as long as global emissions are net positive. Therefore, near term decarbonization is
most valuable. Thankfully, most of the technologies needed to reach net-zero emissions are cost competitive and viable today, but
for a select few technologies needed to decarbonize hard to abate sectors, such as heavy industry and long-haul transportation, and
facilitate carbon dioxide removal. Rapid deployment of solar, onshore and offshore wind, battery storage, smart grid technology,
electric vehicles, heat pumps, and other existing commercial low carbon technologies can catalyze society’s path to net-zero
emissions starting today. GEOS recognizes the urgency of the situation and invests in existing commercially viable technologies that
can be scaled today to enable a net-zero world.

The GEOS team recently engaged with Zurn Elkay Water Solutions to discuss their ESG progress. Zurn is a leading provider of water
management solutions and has significant growth opportunities associated with clean drinking water products. After closing the
acquisition of Elkay Manufacturing that brought more drinking water filtration products into their portfolio, the company made all
employees shareholders and eligible for an annual bonus to boost engagement and retention. Zurn’s management has also held
several town hall meetings to gain feedback from employees and boost employee satisfaction. Moving forward, we plan to track
Zurn’s product roadmap around PFAS filtration given the need to ensure drinking water is free from harmful contaminants.


Despite the fits and starts of clean technology stock performance over the past year, the fundamentals of the companies behind
those stocks – the businesses are progressing. Certainly there are hurdles, from continued labor and supply chain stresses to
higher capital costs. We have emphasized the importance of financial discipline and look to a firm’s returns on investment. A
company which is struggling to scale may have to constantly find capital in the form of loans or equity offerings which dilute
shareholders. Ineffective capital discipline could cause excessive cash “burn”, which, when coupled with a technology which is
struggling to scale commercially will cause an excessive debt burden and leverage. Effective discipline leads to optimal allocations
of capital – a balance between investing for growth, such as research and development, or hiring, versus capital retention for
periods of uncertainty, such as longer sales cycles. Discipline can take the form of capital and financial discipline, but also strong
operational governance – knowing how to bring a new offering to the right market is key and avoids expensive missteps. Discipline
is all important at this time of tight capital.

Despite the many headwinds for our economy, our philosophy is well intact – certainly given all the commitments to net zero, SDGs,
and water conservation, players need solutions.

Renewables growth in the U.S. is apolitical – states are scaling renewables because of the economic vitality – costs are cheaper for
green electrons versus fossil fuels, with less risks and greater functionality. By 2027, we believe Texas could surpass California for
net new utility scale solar, and Texas is already the top state for wind production. Subsidies are catalysts for some industries within
our GEOS themes, but our primary criterium for GEOS is commercial and financial viability before we consider any incentives – that
is gravy.
